具体实施方式detailed description
下面结合附图和具体实施方式对本申请进行详细阐述。应当注意，本申请不应局限于下文所述的具体实施方式。另外，为了简便起见，省略了对与本申请没有直接关联的公知技术的详细描述，以防止对本申请的理解造成混淆。The present application is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the application should not be limited to the specific embodiments described below. In addition, detailed descriptions of well-known techniques that are not directly related to the present application are omitted for the sake of brevity to prevent confusion of the understanding of the present application.
本公开的内容可以应用于NB-IoT系统中，也可以应用到MTC系统中。The content of the present disclosure can be applied to the NB-IoT system, and can also be applied to the MTC system.
在本公开中，在无明确说明的前提下，接入控制(Access Control)和接入禁止(Access Barring)是可以替换的；覆盖增强等级(Coverage enhancement level)也可以描述为增强覆盖等级(Enhanced Coverage level)。本公开中的基站可以是任何类型基站，包含Node B、增强基站eNB，也可以是5G通信系统基站gNB、或者微基站、微微基站、宏基站、家庭基站等；所述小区也可以是上述任何类型基站下的小区。In the present disclosure, Access Control and Access Barring are replaceable without explicit explanation; Coverage enhancement level can also be described as enhanced coverage level (Enhanced) Coverage level). The base station in the present disclosure may be any type of base station, including a Node B, an enhanced base station eNB, or a 5G communication system base station gNB, or a micro base station, a pico base station, a macro base station, a home base station, etc.; the cell may also be any of the above. A cell under a type of base station.
首先明确下述概念：First, the following concepts are clarified:
增强覆盖用户(User Equipment，UE)：指的是增强覆盖内的UE，即UE需要通过增强覆盖功能/机制来接入到小区或网络。User Equipment (UE): refers to the UE within the enhanced coverage, that is, the UE needs to access the cell or network through the enhanced coverage function/mechanism.
增强覆盖等级：增强覆盖技术中将需要增强覆盖的程度分为多个增强覆盖等级。在一些增强覆盖方法中，每一个增强覆盖等级可以对应一套不同的无线参数配置，如随机接入配置(如PRACH(Physical Random Access CHannel)资源)。Enhanced coverage level: The degree of enhancement coverage that will require enhanced coverage is divided into multiple enhanced coverage levels. In some enhanced coverage methods, each enhanced coverage level may correspond to a different set of wireless parameter configurations, such as a random access configuration (such as a PRACH (Physical Random Access CHannel) resource).
不同的实施例之间也可以结合工作。Work can also be combined between different embodiments.
接入禁止参数配置-UE侧Access prohibition parameter configuration - UE side
图1示出了根据本公开实施例的在用户设备UE处执行的方法100的流程图。如图所示，方法100包括以下步骤。FIG. 1 illustrates a flow diagram of a method 100 performed at a user equipment UE, in accordance with an embodiment of the disclosure. As shown, the method 100 includes the following steps.
步骤S110：从基站接收针对一个或多个增强覆盖等级的接入禁止配置。换句话说，该接入禁止配置包含增强覆盖等级信息。该接入禁止配置可以包含与不同增强覆盖等级对应的接入禁止配置参数。Step S110: Receive an access barring configuration for one or more enhanced coverage levels from the base station. In other words, the access barring configuration includes enhanced coverage level information. The access barring configuration may include access barring configuration parameters corresponding to different enhanced coverage levels.
在该步骤中，包含覆盖增强等级信息的接入禁止配置可以承载在系统信息中，可以是系统信息块类型14 SystemInformationBlockType14-NB，也可以是系统信息块类型1 SystemInformationBlockType1-NB，或者主系统信息块MasterInformationBlock-NB，也可以是新引入的系统信息块类型。In this step, the access barring configuration including the coverage enhancement level information may be carried in the system information, which may be the system information block type 14 SystemInformationBlockType14-NB, or the system information block type 1 SystemInformationBlockType1-NB, or the main system information block. MasterInformationBlock-NB can also be a newly introduced system information block type.
步骤S120：根据所接收的接入禁止配置选择与所述UE的增强覆盖等级相对应的接入禁止配置参数。Step S120: Select an access prohibition configuration parameter corresponding to the enhanced coverage level of the UE according to the received access prohibition configuration.
可选地，方法100还可以包括应用所选择的接入禁止配置参数。Optionally, the method 100 may further include applying the selected access barring configuration parameter.
UE的增强覆盖等级为系统定义的增强覆盖等级范围中的一个。例如，系统中支持的增强覆盖等级范围为0，1，2～N，N为增强覆盖等级的最大值，R14中定义的N为3，UE的增强覆盖等级可以为2。The UE's enhanced coverage level is one of the system-defined enhanced coverage level ranges. For example, the enhanced coverage level supported in the system ranges from 0, 1, 2 to N, where N is the maximum value of the enhanced coverage level, N defined in R14 is 3, and the enhanced coverage level of the UE can be 2.
步骤S130：根据所选择的接入禁止配置参数执行接入禁止检查，以确定UE是否被禁止接入所述基站下的小区。Step S130: Perform an access barring check according to the selected access barring configuration parameter to determine whether the UE is prohibited from accessing the cell under the base station.
在该步骤中，UE执行接入禁止检查的过程包括UE根据UE的增强覆盖等级和所选择的接入禁止配置参数，认为接入到该基站下的小区是不被禁止的，或者认为接入到该小区是被禁止的并通知上层建立无线资源控制(Radio Resource Control，RRC)连接失败或者恢复RRC连接失败、挂起 指示(suspend indication)以及应用的接入禁止，并结束该RRC流程。In this step, the process of performing the access barring check by the UE includes that the UE considers that the cell accessing the cell under the base station is not forbidden according to the enhanced coverage level of the UE and the selected access barring configuration parameter, or considers the access The cell is forbidden and the upper layer is notified to establish a Radio Resource Control (RRC) connection failure or restore the RRC connection failure, the suspend indication, and the application access prohibition, and the RRC procedure ends.
可选地，该方法100还包括UE发起RRC连接建立流程或RRC连接恢复流程。这个步骤可以发生在步骤S110之后。Optionally, the method 100 further includes the UE initiating an RRC connection setup procedure or an RRC connection recovery procedure. This step can occur after step S110.
在一个实施例中，包含增强覆盖等级信息的接入禁止配置包含一个比特位图bitmap，其中每一个bit对应于一个或多个增强覆盖等级中的一个增强覆盖等级，用于指示该增强覆盖等级的接入禁止信息。例如，所述bit位的值为“1”，则UE认为所述bit位对应的增强覆盖等级接入到该小区是不被禁止的；所述bit位的值为“0”，则UE认为所述bit位对应的增强覆盖等级接入到该小区是禁止的。上述“1”可以用“TURE”表述；“0”可以用“FALSE”表述，反之亦然。可选地，所述包含增强覆盖等级的接入禁止配置还包括现有版本14系统中已定义的接入禁止配置(对NB＝IoT系统，参见3GPP技术规范36.331章节6.7.3.1SystemInformationBlockType14-NB，对MTC系统，参见3GPP技术规范36.331章节6.3.1SystemInformationBlockType2和SystemInformationBlockType14)，例如，如下所列，在版本14的NB-IoT系统中包含接入禁止种类ab-Category、接入禁止分类位图ab-BarringBitmap、接入禁止异常数据ab-BarringExceptionData、特殊接入分类的接入禁止ab-BarringForSpecialAC等，本公开中称上述每一项为一个接入禁止项目。此时，执行接入禁止检查需要针对包含上述项目在内的接入禁止配置进行接入禁止检查，以得到接入该小区是否被禁止的结论，即接入禁止检查结合包含增强覆盖等级的接入禁止信息和现有系统中的接入禁止项目，也可以理解为增强覆盖等级的接入禁止作为一个接入禁止项目，和其他接入禁止项目并列进行判断。对MTC系统也是如此，现有MTC系统和NB-IoT系统的接入禁止配置不同，但是上述原则同样使用，所以此处不赘述。In one embodiment, the access barring configuration including enhanced coverage level information includes a bit bitmap bitmap, wherein each bit corresponds to one of the one or more enhanced coverage levels for indicating the enhanced coverage level. Access prohibition information. For example, if the value of the bit is "1", the UE considers that the enhanced coverage level corresponding to the bit is not forbidden to access the cell; if the value of the bit is "0", the UE considers It is forbidden to access the enhanced coverage level corresponding to the bit to the cell. The above "1" can be expressed by "TURE"; "0" can be expressed by "FALSE" and vice versa. Optionally, the access barring configuration including the enhanced coverage level further includes an access barring configuration defined in the existing version 14 system (for the NB=IoT system, see 3GPP technical specification 36.331 chapter 6.7.3.1 SystemInformationBlockType14-NB, For the MTC system, see 3GPP Technical Specification 36.331 Section 6.3.1 SystemInformationBlockType2 and SystemInformationBlockType14), for example, as listed below, the access prohibition category ab-Category, access prohibition classification bitmap ab-BarringBitmap is included in the version 14 NB-IoT system. Access prohibition abnormal data ab-BarringExceptionData, special access classification access prohibition ab-BarringForSpecialAC, etc., in the present disclosure, each of the above items is an access prohibition item. At this time, performing the access prohibition check needs to perform an access prohibition check for the access prohibition configuration including the above items, to obtain a conclusion that access to the cell is prohibited, that is, the access prohibition check is combined with the enhanced coverage level. The entry prohibition information and the access prohibition item in the existing system can also be understood as the access prohibition of the enhanced coverage level as an access prohibition item, and judging in parallel with other access prohibition items. The same is true for the MTC system. The existing MTC system and the NB-IoT system have different access prohibition configurations, but the above principles are also used, so they are not described here.

该bitmap可以包含在主系统信息块，或者系统信息块1，系统信息块14，或其他系统信息块中。举例来说，在NB-IoT系统中，该实施例在3GPP技术规范协议中表示如下：The bitmap may be included in the main system information block, or system information block 1, system information block 14, or other system information block. For example, in the NB-IoT system, this embodiment is expressed in the 3GPP Technical Specification Protocol as follows:

Figure PCTCN2018082493-appb-000003
在一个实施例中，包含增强覆盖等级信息的接入禁止配置包含每个增强覆盖等级对应的接入禁止配置信息(也称为接入禁止配置参数)。每个增强覆盖等级对应的接入禁止配置信息包含现有系统版本中已定义的接入禁止配置项目，如前所述。可以理解为，接入禁止配置中包含一个接入禁止信息列表，列表中的每一组配置包含现有系统版本中已定义的接入禁止项目，并对应一个增强覆盖等级。In one embodiment, the access barring configuration including enhanced coverage level information includes access barring configuration information (also referred to as an access barring configuration parameter) corresponding to each enhanced coverage level. The access barring configuration information corresponding to each enhanced coverage level includes an access barring configuration item that has been defined in the existing system version, as previously described. It can be understood that the access prohibition configuration includes an access prohibition information list, and each group configuration in the list includes an access prohibition item defined in the existing system version, and corresponds to an enhanced coverage level.
举例来说，在NB-IoT系统中，该实施例在3GPP技术规范协议中表示如下：For example, in the NB-IoT system, this embodiment is expressed in the 3GPP Technical Specification Protocol as follows:
Figure PCTCN2018082493-appb-000004
Figure PCTCN2018082493-appb-000004
可选地，在该实施例中，若一个增强覆盖等级对应的接入禁止配置不存在，在认为该增强覆盖等级采用与另一个增强覆盖等级相同的接入禁止配置(例如，另一个增强覆盖等级指的是最小索引值的增强覆盖等级，或者是最大索引值的增强覆盖等级，或者是前一个索引值的增强覆盖等级)。Optionally, in this embodiment, if an access prohibition configuration corresponding to an enhanced coverage level does not exist, the enhanced coverage level is considered to be the same as the other enhanced coverage level (for example, another enhanced coverage). The level refers to the enhanced coverage level of the minimum index value, or the enhanced coverage level of the largest index value, or the enhanced coverage level of the previous index value).
例如，在MTC系统中，若获取的接入禁止配置中包含每增强覆盖等级接入禁止信息列表(Ac-barringinfo-perCElevel-list)，UE根据其增强覆盖等级在该列表中选择相对应的每增强覆盖等级接入禁止信息条目(Ac-barringinfo-perCElevel entry)，用于接入禁止检查。若获取的接入禁止配置中包含每增强覆盖等级接入禁止配置信息元素(Ac-barringconfig-per CElevel-list)，UE根据其增强覆盖等级在该列表中选择相对应的每增强覆盖等级接入截止配置条目(Ac-barringconfig-per CElevel-list entry)。若获取的接入禁止配置中包含每增强覆盖等级接入禁止忽略(Ac-barringskipforMMTELvoice-perCElevelList或Ac-barringskipforMMTELvedio-perCElevelList或Ac-barringskipforSMS-perCElevelList)，则UE根据其增强覆盖等级在该列表中选择相对应的接入禁止忽略条目(Ac-barringskipforMMTELvoice或Ac-barringskipforMMTELvedio或Ac-barringskipforSMS)。若获取的接入禁止配置中包含一个或多个每增强覆盖等级每类型接入禁止列表(barringper-categorylist-perCElevel-list)，则UE根据其增强覆盖等级在一个或多个每增强覆盖等级每类型接入禁止列表中选择一个相对应的列表(barringper-categorylist)。若获取的接入禁止配置中包含每增强覆盖等级每ACDC(Application specific Congestion control for Data Communication)类型接入禁止列表(barringperACDC-category-perCElevel-List)，则UE根据其增强覆盖等级在该列表中选择相对应的每增强覆盖等级每ACDC类型每接入禁止条目(barringperACDC-category)。对于EAB(Extended Access barring)机制，若系统信息块14中包含每增强覆盖等级扩展接入禁止配置列表(EAB-config-perCElevelList)；则UE根据其增强覆盖等级在该列表中选择相对应的扩展接入禁止配置条目(EAB-config)。For example, in the MTC system, if the obtained access prohibition configuration includes an per-enhanced coverage level access prohibition information list (Ac-barringinfo-perCElevel-list), the UE selects a corresponding one in the list according to its enhanced coverage level. An enhanced coverage level access prohibition information entry (Ac-barringinfo-perCElevel entry) is used to access the prohibition check. If the acquired access barring configuration includes an en-barring configure-per CE level-list, the UE selects a corresponding per-enhanced coverage level in the list according to the enhanced coverage level. The cut-off configuration entry (Ac-barringconfig-per CElevel-list entry). If the obtained access barring configuration includes an access-level exclusion prohibition (Ac-barringskipfor MMTELvoice-perCElevelList or Ac-barringskipfor MMTELvedio-perCElevelList or Ac-barringskipforSMS-perCElevelList), the UE selects a phase in the list according to its enhanced coverage level. The corresponding access prohibition ignores the entry (Ac-barringskipforMMTELvoice or Ac-barringskipforMMTELvedio or Ac-barringskipforSMS). If the acquired access barring configuration includes one or more per-enhanced coverage level per-type access barring list (barringper-categorylist-perCElevel-list), the UE is in each of the enhanced coverage levels according to its enhanced coverage level. Select a corresponding list (barringper-categorylist) in the type access barring list. If the obtained access prohibition configuration includes an application specific congestion control for Data Communication type access prohibition list (barringperACDC-category-perCElevel-List), the UE is in the list according to its enhanced coverage level. Select each corresponding enhanced coverage level per ACDC type per access barring entry (barringperACDC-category). For the EAB (Extended Access Barring) mechanism, if the system information block 14 includes an enhanced coverage level extended access prohibition configuration list (EAB-config-perCElevelList), the UE selects a corresponding extension in the list according to its enhanced coverage level. Access prohibited configuration entry (EAB-config).
在一个实施例中，包含增强覆盖等级信息的接入禁止配置包含一个增强覆盖等级数值X1。可选地，所述接入禁止配置还包含现有系统版本中的接入禁止项目。若UE的增强覆盖等级小于或小于等于X1，则UE认为接入到该小区为禁止的，若UE的增强覆盖等级大于或大于等于X1，则UE认为接入到该小区为不被禁止的；反之亦然，若UE的增强覆盖等级小于或小于等于X1，则UE认为接入到该小区为不被禁止的，若UE的增强覆盖等级大于或大于等于X1，则UE认为接入到该小区为被禁止的。可选地， X1可以理解为最大的接入禁止增强覆盖等级，或最小的接入禁止增强覆盖等级，或最大的不被接入禁止增强覆盖等级，或最小的不被接入禁止增强覆盖等级。此外，如前述实施例所述，执行接入禁止检查需要针对包含现有系统接入禁止项目在内进行接入禁止检查，以得到接入该小区是否被禁止的结论，即接入禁止检查结合包含增强覆盖等级的接入禁止检查和现有系统中的接入禁止项目的检查，以最终得带一个接入小区是否被禁止的判断；也可以理解为增强覆盖等级的接入禁止作为一个接入禁止项目，和其他接入禁止项目并列进行判断。In one embodiment, the access barring configuration including enhanced coverage level information includes an enhanced coverage level value X1. Optionally, the access barring configuration further includes an access barring item in an existing system version. If the enhanced coverage level of the UE is less than or equal to X1, the UE considers that access to the cell is prohibited. If the enhanced coverage level of the UE is greater than or equal to X1, the UE considers that access to the cell is not prohibited; If the enhanced coverage level of the UE is less than or equal to X1, the UE considers that access to the cell is not forbidden. If the enhanced coverage level of the UE is greater than or equal to X1, the UE considers that the UE is connected to the cell. Forbidden. Optionally, X1 can be understood as the maximum access prohibition enhanced coverage level, or the minimum access prohibition enhanced coverage level, or the largest non-access prohibition enhanced coverage level, or the smallest non-access prohibition enhanced coverage level. . In addition, as described in the foregoing embodiment, performing an access barring check needs to perform an access barring check for including an existing system access barring item to obtain a conclusion that access to the cell is prohibited, that is, the access prohibition check is combined. The access prohibition check including the enhanced coverage level and the check of the access prohibition item in the existing system are performed to finally determine whether an access cell is prohibited. It can also be understood as an access restriction of the enhanced coverage level as a connection. Enter prohibited items and judge alongside other access prohibited items.

The other access barring configuration includes an access barring configuration parameter that has been defined in an existing system. The UE determines its enhanced coverage level in accordance with methods described in other embodiments of the present disclosure. If the enhanced coverage level of the UE is less than or equal to X2, the UE considers that access to the cell is not prohibited. If the enhanced coverage level of the UE is greater than or equal to X2, the UE performs configuration based on the other access prohibition configuration. Access prohibition check. In another mode, if the enhanced coverage level of the UE is less than or equal to X2, the UE performs an access prohibition check based on the other access prohibition configuration. If the enhanced coverage level of the UE is greater than or equal to X2, the UE considers Access to the cell is not prohibited. In another mode, if the enhanced coverage level of the UE is less than or equal to X2, the UE considers that access to the cell is prohibited. If the enhanced coverage level of the UE is greater than or equal to X2, the UE is based on the other connection. Inhibit configuration, perform access prohibition check. In another mode, if the enhanced coverage level of the UE is less than or equal to X2, the UE performs an access prohibition check based on the other access prohibition configuration. If the enhanced coverage level of the UE is greater than or equal to X2, the UE considers Access to the cell is prohibited. Optionally, X2 can be understood as the maximum access prohibition enhanced coverage level, or the minimum access prohibition enhanced coverage level, or the largest non-access prohibition enhanced coverage level, or the smallest non-access prohibition enhanced coverage level. .

在上述示例中，本实施例的另一种方法可以阐述为：若UE的增强覆盖等级小于或小于等于X2，则UE认为所述接入禁止配置中的参数配置适用，并依据所述接入禁止配置中的参数配置进行接入禁止检查，若UE的增强覆盖等级大于或大于等于X2，则UE认为接入到该小区为不被禁止的，或者说认为所述接入禁止配置中的参数配置不使用，不需要继续进行接入禁止检查；反之亦然，若UE的增强覆盖等级小于或小于等于X2，则UE认为接入到该小区为不被禁止的，或者说认为所述接入禁止配置中的参数配置不使用，不需要继续进行接入禁止检查，若UE的增强覆盖等级大于或大于等于X2，则UE认为所述接入禁止配置中的参数配置适用，并依据所述接入禁止配置中的参数配置进行接入禁止检查。可选地，X2可以理解为最大的接入禁止增强覆盖等级，或最小的接入禁止增强覆盖等级，或最大的不被接入禁止增强覆盖等级，或最小的不被接入禁止增强覆盖等级。In the above example, another method in this embodiment may be as follows: if the enhanced coverage level of the UE is less than or equal to X2, the UE considers that the parameter configuration in the access prohibition configuration is applicable, and according to the access The parameter configuration in the configuration is prohibited from performing the access prohibition check. If the enhanced coverage level of the UE is greater than or equal to X2, the UE considers that access to the cell is not prohibited, or considers the parameter in the access prohibition configuration. If the configuration is not used, the access prohibition check does not need to be continued. If the enhanced coverage level of the UE is less than or equal to X2, the UE considers that access to the cell is not prohibited, or considers the access. The parameter configuration in the configuration is not used, and the access prohibition check is not required. If the enhanced coverage level of the UE is greater than or equal to X2, the UE considers that the parameter configuration in the access prohibition configuration is applicable, and according to the connection. Enter the parameter configuration in the forbidden configuration to perform the access prohibition check. Optionally, X2 can be understood as the maximum access prohibition enhanced coverage level, or the minimum access prohibition enhanced coverage level, or the largest non-access prohibition enhanced coverage level, or the smallest non-access prohibition enhanced coverage level. .
图2示出了根据本公开实施例的一种在基站处执行的方法200的流程图。如图所示，方法200包括以下步骤。2 shows a flow diagram of a method 200 performed at a base station in accordance with an embodiment of the disclosure. As shown, method 200 includes the following steps.
步骤S210：向用户设备UE发送针对一个或多个增强覆盖等级的接入禁止配置。换句话说，该接入禁止配置包含增强覆盖等级信息。Step S210: Send an access barring configuration for one or more enhanced coverage levels to the user equipment UE. In other words, the access barring configuration includes enhanced coverage level information.
所述接入禁止配置可以包含在系统信息中。可选地，基站还可以根据网络负载状况和网络中增强覆盖等级用户的分布状况，决定是否下发所述包含增强覆盖等级信息的接入禁止配置。The access barring configuration may be included in system information. Optionally, the base station may further determine, according to the network load status and the distribution status of the enhanced coverage level user in the network, whether to send the access prohibition configuration that includes the enhanced coverage level information.
所述包含增强覆盖等级信息的接入禁止配置，可以是下述几种方法。The access prohibition configuration including the enhanced coverage level information may be the following methods.
在一个实施例中，包含增强覆盖等级信息的接入禁止配置包含一个比特位图bitmap，其中每一个bit对应于一个增强覆盖等级，用于指示该增强覆盖等级的接入禁止信息。例如，所述bit位的值为“1”，则所述bit位对应的增强覆盖等级接入到该小区是不被禁止的；所述bit位的值为“0”，则所述bit位对应的增强覆盖等级接入到该小区是禁止的。上述“1”可以用“TURE”表述；“0”可以用“FALSE”表述，反之亦然。可选地，所述包含增强覆盖等级的接入禁止配置还包括现有版本14系统中已定义的接入禁止配置(对NB＝IoT系统，参见3GPP技术规范36.331章节6.7.3.1SystemInformationBlockType14-NB，对MTC系统，参见3GPP技术规范 36.331章节6.3.1SystemInformationBlockType2和SystemInformationBlockType14)，例如，如下列，在版本14的NB-IoT系统中包含接入禁止种类ab-Category、接入禁止分类位图ab-BarringBitmap、接入禁止异常数据ab-BarringExceptionData、特殊接入分类的接入禁止ab-BarringForSpecialAC等，本公开中称上述每一项为一个接入禁止项目。此时，执行接入禁止检查需要针对包含上述项目在内的接入禁止配置进行接入禁止检查，以得到接入该小区是否被禁止的结论，即接入禁止检查结合包含增强覆盖等级的接入禁止信息和现有系统中的接入禁止项目，也可以理解为增强覆盖等级的接入禁止作为一个接入禁止项目，和其他接入禁止项目并列进行判断。对MTC系统也是如此，现有MTC系统和NB-IoT系统的接入禁止配置不同，但是上述原则同样使用，所以此处不赘述。In one embodiment, the access barring configuration including enhanced coverage level information includes a bit bitmap bitmap, wherein each bit corresponds to an enhanced coverage level for indicating access barring information for the enhanced coverage level. For example, if the value of the bit is "1", the enhanced coverage level corresponding to the bit is not forbidden to access the cell; if the value of the bit is "0", the bit is It is forbidden to access the corresponding enhanced coverage level to the cell. The above "1" can be expressed by "TURE"; "0" can be expressed by "FALSE" and vice versa. Optionally, the access barring configuration including the enhanced coverage level further includes an access barring configuration defined in the existing version 14 system (for the NB=IoT system, see 3GPP technical specification 36.331 chapter 6.7.3.1 SystemInformationBlockType14-NB, For the MTC system, see 3GPP Technical Specification 36.331 Section 6.3.1 SystemInformationBlockType2 and SystemInformationBlockType14). For example, as shown below, the version 14 NB-IoT system includes an access barring type ab-Category, an access barring class bitmap ab-BarringBitmap, The access prohibition abnormal data ab-BarringExceptionData, the special access classification access prohibition ab-BarringForSpecialAC, etc., in the present disclosure, each of the above items is an access prohibition item. At this time, performing the access prohibition check needs to perform an access prohibition check for the access prohibition configuration including the above items, to obtain a conclusion that access to the cell is prohibited, that is, the access prohibition check is combined with the enhanced coverage level. The entry prohibition information and the access prohibition item in the existing system can also be understood as the access prohibition of the enhanced coverage level as an access prohibition item, and judging in parallel with other access prohibition items. The same is true for the MTC system. The existing MTC system and the NB-IoT system have different access prohibition configurations, but the above principles are also used, so they are not described here.

The method 500 is for performing access barring at the UE RRC layer at the UE. As shown, method 500 includes the following steps.
步骤S510：根据测量的参考信号接收功率RSRP确定UE的增强覆盖等级。Step S510: Determine an enhanced coverage level of the UE according to the measured reference signal received power RSRP.
在一个实施例中，步骤S510可以包括：UE RRC层根据测量的RSRP与预定RSRP门限的比较结果来确定UE的增强覆盖等级。In an embodiment, step S510 may include: the UE RRC layer determines an enhanced coverage level of the UE according to a comparison result of the measured RSRP and the predetermined RSRP threshold.
UE RRC层根据测量的RSRP确定UE的增强覆盖等级。例如，如果系统支持增强覆盖等级的范围为0～N，则如果配置了增强覆盖等级N的RSRP 门限th_N且所测量的RSRP小于该门限值th_N且UE支持增强覆盖等级N，则UE或UE RRC层认为其处于增强覆盖等级N；否则若配置了增强覆盖等级N-1的RSRP门限th_N-1且所测量的RSRP小于该门限值th_N-1且UE支持增强覆盖等级N-1，则UE或UE RRC层认为其处于增强覆盖等级N-1；否则若配置了增强覆盖等级N-2的RSRP门限th_N且所测量的RSRP小于该门限值th_N-2且UE支持增强覆盖等级N-2，则UE或UE RRC层认为其处于增强覆盖等级N-2；以此类推，否则若配置了增强覆盖等级1的RSRP门限th_1且所测量的RSRP小于该门限值th_1，则UE或UE RRC层认为其处于增强覆盖等级1；否则认为其处于增强覆盖等级0。The UE RRC layer determines an enhanced coverage level of the UE according to the measured RSRP. For example, if the system supports an enhanced coverage level ranging from 0 to N, if the RSRP threshold th_N of the enhanced coverage level N is configured and the measured RSRP is less than the threshold value th_N and the UE supports the enhanced coverage level N, the UE or UE The RRC layer considers that it is in the enhanced coverage level N; otherwise, if the RSRP threshold th_N-1 of the enhanced coverage level N-1 is configured and the measured RSRP is less than the threshold value th_N-1 and the UE supports the enhanced coverage level N-1, then The UE or the UE RRC layer considers that it is in the enhanced coverage level N-1; otherwise, if the RSRP threshold th_N of the enhanced coverage level N-2 is configured and the measured RSRP is less than the threshold value th_N-2 and the UE supports the enhanced coverage level N- 2, the UE or the UE RRC layer considers that it is in the enhanced coverage level N-2; and so on, otherwise if the RSRP threshold th_1 of the enhanced coverage level 1 is configured and the measured RSRP is less than the threshold value th_1, the UE or the UE The RRC layer considers it to be at an enhanced coverage level of 1; otherwise it is considered to be at an enhanced coverage level of zero.
在该实施例中，UE从基站获取所述增强覆盖等级的RSRP门限值配置。该配置可以是包含在系统信息中，如系统信息块14。In this embodiment, the UE acquires the RSRP threshold configuration of the enhanced coverage level from the base station. This configuration may be included in system information, such as system information block 14.
可选地，在该实施例中，所述测量也可以是测量的参考信号接收质量(Reference Signal Received Quality，RSRQ)；或者RSRP和RSRQ。Optionally, in this embodiment, the measurement may also be a measured Reference Signal Received Quality (RSRQ); or RSRP and RSRQ.
在另一个实施例中，步骤S510可以包括：UE媒体访问控制(MAC)层根据测量的RSRP与预定RSRP门限的比较结果来确定UE的增强覆盖等级，并向UE RRC层指示所确定的增强覆盖等级。In another embodiment, step S510 may include: the UE medium access control (MAC) layer determines an enhanced coverage level of the UE according to the comparison result of the measured RSRP and the predetermined RSRP threshold, and indicates the determined enhanced coverage to the UE RRC layer. grade.
在该步骤中，UE MAC层根据测量的RSRP决定UE的增强覆盖等级，采用现有技术中随机接入中的配置参数。例如：若上层在rsrp-ThresholdsPrachInfoList中配置了增强覆盖等级3的RSRP门限且所测量的RSRP小于该增强覆盖等级3的门限值且UE支持增强覆盖等级3，则MAC实体认为其处于增强覆盖等级3；否则若上层在rsrp-ThresholdsPrachInfoList中配置了增强覆盖等级2的RSRP门限且所测量的RSRP小于该增强覆盖等级2的门限值且UE支持增强覆盖等级2，则MAC实体认为其处于增强覆盖等级2；否则若上层在rsrp-ThresholdsPrachInfoList中配置了增强覆盖等级1的RSRP门限且所测量的RSRP小于该覆盖增强等级的门限值，则MAC实体认为其处于增强覆盖等级1；否则MAC实体认为其处于增强覆盖等级0。In this step, the UE MAC layer determines the enhanced coverage level of the UE according to the measured RSRP, and adopts the configuration parameters in the random access in the prior art. For example, if the upper layer configures the RSRP threshold of the enhanced coverage level 3 in the rsrp-ThresholdsPrachInfoList and the measured RSRP is smaller than the threshold of the enhanced coverage level 3 and the UE supports the enhanced coverage level 3, the MAC entity considers that it is in the enhanced coverage level. 3; otherwise, if the upper layer configures the RSRP threshold of the enhanced coverage level 2 in the rsrp-ThresholdsPrachInfoList and the measured RSRP is smaller than the threshold of the enhanced coverage level 2 and the UE supports the enhanced coverage level 2, the MAC entity considers that it is in the enhanced coverage. Level 2; otherwise, if the upper layer configures the RSRP threshold of the enhanced coverage level 1 in the rsrp-ThresholdsPrachInfoList and the measured RSRP is smaller than the threshold of the coverage enhancement level, the MAC entity considers that it is in the enhanced coverage level 1; otherwise the MAC entity considers It is at an enhanced coverage level of zero.
步骤S520：UE RRC层根据与所确定的增强覆盖等级相对应的接入禁止配置执行接入禁止检查。Step S520: The UE RRC layer performs an access prohibition check according to the access prohibition configuration corresponding to the determined enhanced coverage level.
图6示出了根据本公开实施例的在用户设备UE处执行的方法600的流程图。方法600用于在UE处在UE RRC层执行接入禁止。如图所示，方 法600包括以下步骤。FIG. 6 shows a flow diagram of a method 600 performed at a user equipment UE, in accordance with an embodiment of the disclosure. The method 600 is for performing access barring at the UE RRC layer at the UE. As shown, the method 600 includes the following steps.
步骤S610：UE RRC层根据成功接收寻呼消息后所确定的重复等级来确定UE的增强覆盖等级。Step S610: The UE RRC layer determines an enhanced coverage level of the UE according to the repetition level determined after successfully receiving the paging message.
在现有系统中，UE根据3GPP技术规范36.213中表9.1.5.4来确定UE的重复等级r1、r2、r3、r4，其中rmax的值以上层配置的参数mPDCCH-NumRepetition-Paging来替换。In the existing system, the UE determines the repetition level r1, r2, r3, r4 of the UE according to Table 9.1.5.4 in the 3GPP technical specification 36.213, where the value of rmax is replaced by the parameter mPDCCH-NumRepetition-Paging configured above the layer.

1616 11 44 88 1616
88 11 22 44 88
在该实施例中，所述重复等级与用于接入禁止判断的增强覆盖等级一一对应，UE以此来根据获得的重复等级确定其用于接入禁止判断的增强覆盖等级。举例来说，如果所述重复等级确定为r1，则UE确定其增强覆盖等级为3；如果所述重复等级确定为r2，则UE确定其增强覆盖等级为2；如果所述重复等级确定为r3，则UE确定其增强覆盖等级为1；如果所述重复等级确定为r4，则UE确定其增强覆盖等级为0。In this embodiment, the repetition level is in one-to-one correspondence with the enhanced coverage level for the access inhibition determination, and the UE determines the enhanced coverage level for the access inhibition determination according to the obtained repetition level. For example, if the repetition level is determined to be r1, the UE determines that its enhanced coverage level is 3; if the repetition level is determined to be r2, the UE determines that its enhanced coverage level is 2; if the repetition level is determined to be r3 Then, the UE determines that its enhanced coverage level is 1; if the repetition level is determined to be r4, the UE determines that its enhanced coverage level is 0.
步骤S620：UE RRC层根据与所确定的增强覆盖等级相对应的接入禁止配置执行接入禁止检查。Step S620: The UE RRC layer performs an access prohibition check according to the access prohibition configuration corresponding to the determined enhanced coverage level.
图7示出了根据本公开实施例的在UE侧实现接入禁止的一个方法示意图，具体包括以下步骤：FIG. 7 is a schematic diagram of a method for implementing access barring on a UE side according to an embodiment of the present disclosure, specifically including the following steps:
步骤S710：UE或UE RRC层发起无线资源控制连接建立或恢复流程。Step S710: The UE or the UE RRC layer initiates a radio resource control connection establishment or recovery procedure.
步骤S720：确定UE的增强覆盖等级，或者获得UE的增强覆盖等级。UE RRC层根据测量的RSRP确定UE的增强覆盖等级。Step S720: Determine an enhanced coverage level of the UE, or obtain an enhanced coverage level of the UE. The UE RRC layer determines an enhanced coverage level of the UE according to the measured RSRP.
可选地，步骤S720可以发生在步骤S730触发后执行，如在步骤S730A之前；或者步骤S720可以在步骤S710之前执行。Alternatively, step S720 may occur after the triggering of step S730, as before step S730A; or step S720 may be performed before step S710.
步骤S730：UE RRC层执行接入禁止检查。步骤S730可以具体包括步骤S730A和S730B。Step S730: The UE RRC layer performs an access prohibition check. Step S730 may specifically include steps S730A and S730B.
步骤S730A：UE RRC层根据现有系统版本中的接入禁止项目执行接入禁止检查；Step S730A: The UE RRC layer performs an access prohibition check according to the access prohibition item in the existing system version.
步骤S730B：UE RRC层根据UE的增强覆盖等级和所获取的包含增强覆盖等级的接入禁止配置执行接入禁止检查。Step S730B: The UE RRC layer performs an access prohibition check according to the enhanced coverage level of the UE and the acquired access prohibition configuration including the enhanced coverage level.
若接入禁止检查结果为认为接入该小区是禁止的，则执行步骤S740；若接入禁止检查结果认为接入该小区是不被禁止的，则执行步骤S750。If the access prohibition check result is that the access to the cell is prohibited, step S740 is performed; if the access prohibition check result is that the access to the cell is not prohibited, step S750 is performed.
步骤S740：若接入禁止检查结果为认为接入该小区是禁止的，通知上层建立RRC连接失败或者恢复RRC连接失败、挂起指示(suspend indication)以及应用的接入禁止，并结束该RRC流程。Step S740: If the access prohibition check result is that the access to the cell is prohibited, notify the upper layer to establish an RRC connection failure or restore the RRC connection failure, suspend indication, and application access prohibition, and end the RRC procedure. .
步骤S750：继续无线资源控制连接建立或恢复流程，如应用默认的物理信道配置，应用默认的MAC主配置，应用公共控制信道(Common Control CHannel，CCCH)配置，开启定时器T300等。在该实施例中，步骤S730A和步骤S730B的次序可以交换。或者步骤S730B可以在步骤S730A过程中执行。即步骤S730A中包含对现有系统接入禁止检查中多个接入禁止项目的检查，那么步骤S730B中基于增强覆盖等级的接入禁止检查可以看做一个独立的检查项目，该检查项目的次序可以置于步骤S730A过程中多个检查项目的任何两个检查项目之间。Step S750: Continue the RRC connection establishment or recovery process, such as applying the default physical channel configuration, applying the default MAC master configuration, applying a Common Control CHannel (CCCH) configuration, and starting the timer T300. In this embodiment, the order of step S730A and step S730B can be exchanged. Or step S730B may be performed in the process of step S730A. That is, in step S730A, the check of the plurality of access prohibition items in the existing system access prohibition check is included, and then the access prohibition check based on the enhanced coverage level in step S730B can be regarded as an independent check item, the order of the check items. It may be placed between any two inspection items of a plurality of inspection items in the process of step S730A.
在一个实施例中，UE RRC层根据测量的RSRP确定UE的增强覆盖等级。例如，如果系统支持增强覆盖等级的范围为0～N，则如果配置了增强覆盖等级N的RSRP门限th_N且所测量的RSRP小于该门限值th_N且UE支持增强覆盖等级N，则UE或UE RRC层认为其处于增强覆盖等级N；否则若配置了增强覆盖等级N-1的RSRP门限th_N-1且所测量的RSRP小于该门限值th_N-1且UE支持增强覆盖等级N-1，则UE或UE RRC层认为其处于增强覆盖等级N-1；否则若配置了增强覆盖等级N-2的RSRP门限th_N且所测量的RSRP小于该门限值th_N-2且UE支持增强覆盖等级N-2，则UE或UE RRC层认为其处于增强覆盖等级N-2；以此类推，否则若配置了增强覆盖等级1的RSRP门限th_1且所测量的RSRP小于该门限值th_1，则UE或UE RRC层认为其处于增强覆盖等级1；否则认为其处于增强覆盖等级0。In one embodiment, the UE RRC layer determines an enhanced coverage level of the UE based on the measured RSRP. For example, if the system supports an enhanced coverage level ranging from 0 to N, if the RSRP threshold th_N of the enhanced coverage level N is configured and the measured RSRP is less than the threshold value th_N and the UE supports the enhanced coverage level N, the UE or UE The RRC layer considers that it is in the enhanced coverage level N; otherwise, if the RSRP threshold th_N-1 of the enhanced coverage level N-1 is configured and the measured RSRP is less than the threshold value th_N-1 and the UE supports the enhanced coverage level N-1, then The UE or the UE RRC layer considers that it is in the enhanced coverage level N-1; otherwise, if the RSRP threshold th_N of the enhanced coverage level N-2 is configured and the measured RSRP is less than the threshold value th_N-2 and the UE supports the enhanced coverage level N- 2, the UE or the UE RRC layer considers that it is in the enhanced coverage level N-2; and so on, otherwise if the RSRP threshold th_1 of the enhanced coverage level 1 is configured and the measured RSRP is less than the threshold value th_1, the UE or the UE The RRC layer considers it to be at an enhanced coverage level of 1; otherwise it is considered to be at an enhanced coverage level of zero.
在该实施例中，UE从基站获取所述增强覆盖等级的RSRP门限值配置。该配置可以是包含在系统信息中，如系统信息块14。In this embodiment, the UE acquires the RSRP threshold configuration of the enhanced coverage level from the base station. This configuration may be included in system information, such as system information block 14.
可选地，在该实施例中，所述测量也可以是测量的参考信号接收质量(Reference Signal Received Quality，RSRQ)；或者RSRP和RSRQ。Optionally, in this embodiment, the measurement may also be a measured Reference Signal Received Quality (RSRQ); or RSRP and RSRQ.
在一个实施例中，UE RRC层从UE MAC层获取UE的增强覆盖等级。具体地，UE RRC层向UE MAC层指示获取UE的增强覆盖等级，UE MAC层确定UE的增强覆盖等级，并将所确定的增强覆盖等级通知给UE RRC层。In one embodiment, the UE RRC layer acquires an enhanced coverage level of the UE from the UE MAC layer. Specifically, the UE RRC layer indicates to the UE MAC layer to acquire an enhanced coverage level of the UE, and the UE MAC layer determines an enhanced coverage level of the UE, and notifies the UE RRC layer of the determined enhanced coverage level.
UE MAC层根据测量的RSRP确定UE的增强覆盖等级，这可以采用现有技术中随机接入中的配置参数来实现。例如：若上层在rsrp-ThresholdsPrachInfoList中配置了增强覆盖等级3的RSRP门限且所测量的RSRP小于该增强覆盖等级3的门限值且支持增强覆盖等级3，则MAC实体认为其处于增强覆盖等级3；否则若上层在rsrp-ThresholdsPrachInfoList中配置了增强覆盖等级2的RSRP门限且所测量的RSPR小于该增强覆盖等级2的门限值且支持增强覆盖等级2，则MAC实体认为其处于增强覆盖等级2；否则若上层在rsrp-ThresholdsPrachInfoList中配置了增强覆盖等级1的RSRP门限且所测量的RSRP小于该覆盖增强等级的门限值，则实体认为其处于增强覆盖等级1；否则MAC实体认为其处于增强覆盖等级0。The UE MAC layer determines the enhanced coverage level of the UE according to the measured RSRP, which can be implemented by using configuration parameters in the random access in the prior art. For example, if the upper layer configures the RSRP threshold of the enhanced coverage level 3 in the rsrp-ThresholdsPrachInfoList and the measured RSRP is smaller than the threshold of the enhanced coverage level 3 and supports the enhanced coverage level 3, the MAC entity considers that it is in the enhanced coverage level 3 Otherwise, if the upper layer configures the RSRP threshold of the enhanced coverage level 2 in the rsrp-ThresholdsPrachInfoList and the measured RSPR is less than the threshold of the enhanced coverage level 2 and supports the enhanced coverage level 2, the MAC entity considers that it is in the enhanced coverage level 2 Otherwise, if the upper layer configures the RSRP threshold of the enhanced coverage level 1 in the rsrp-ThresholdsPrachInfoList and the measured RSRP is less than the threshold of the coverage enhancement level, the entity considers that it is at the enhanced coverage level 1; otherwise the MAC entity considers that it is in the enhanced Cover level 0.
在一个实施例中，UE RRC层根据成功接收寻呼消息后所确定的重复等级来确定其用于接入禁止判断的增强覆盖等级，如以上结合图6的描述所述。In one embodiment, the UE RRC layer determines its enhanced coverage level for access barring determination based on the level of repetition determined after successfully receiving the paging message, as described above in connection with FIG.
在一个实施例中，在RRC连接建立流程中或RRC连接恢复流程中，或者说在RRC连接建立流程结束之前或RRC连接恢复流程结束之前，继续增强覆盖等级评估/确定。若所确定的增强覆盖等级与用于上次接入禁止检查的增强覆盖等级不同，则UE将基于确定的其增强覆盖等级执行接入禁止检查，若接入到所述小区是被禁止的，则若低层有正在进行的随机接入流程，指示低层放弃正在进行的随机接入流程；向上层告知建立RRC连接失败后恢复RRC连接失败及挂起指示和应用了接入禁止，结束该RRC流程。In one embodiment, the enhanced coverage level assessment/determination continues in the RRC connection setup procedure or the RRC connection recovery procedure, or before the end of the RRC connection setup procedure or before the RRC connection recovery procedure ends. If the determined enhanced coverage level is different from the enhanced coverage level used for the last access barring check, the UE will perform an access barring check based on the determined enhanced coverage level, if access to the cell is prohibited, If the lower layer has an ongoing random access procedure, the lower layer is instructed to abandon the ongoing random access procedure; the upper layer is notified that the RRC connection failure is failed, the RRC connection failure and the suspension indication are restored, and the access prohibition is applied, and the RRC procedure is terminated. .

图8示出了根据本公开实施例的在基站处执行的方法800的流程图。方法800用于在基站处实施在RRC层的接入禁止。如图所示，方法800包括以下步骤。FIG. 8 shows a flow diagram of a method 800 performed at a base station in accordance with an embodiment of the disclosure. Method 800 is for implementing access barring at the RRC layer at the base station. As shown, method 800 includes the following steps.
步骤S810：向用户设备UE发送增强覆盖等级门限值配置，所述增强覆盖等级门限值配置包含一个或多个增强覆盖等级门限值，每一个增强覆盖等级门限值对应于一个增强覆盖等级。Step S810: Send an enhanced coverage level threshold configuration to the user equipment UE, where the enhanced coverage level threshold configuration includes one or more enhanced coverage level thresholds, and each enhanced coverage level threshold corresponds to an enhanced coverage. grade.
例如，基站可以通过广播信息向UE发送增强覆盖等级门限值配置。该配置信息可以包含在系统信息中。For example, the base station may send an enhanced coverage level threshold configuration to the UE through the broadcast information. This configuration information can be included in the system information.
所述增强覆盖等级门限值配置可以是一个门限值列表，包含N个门限 值配置，每个门限值对应一个增强覆盖等级，N为系统支持的最大覆盖等级索引值。例如，若系统支持的最大覆盖等级索引值为3，则基站配置的门限值列表包含3个门限值配置，其中门限值3对应增强覆盖等级3的门限值，门限值2对应增强覆盖等级2的门限值；门限值1对应增强覆盖等级1的门限值。The enhanced coverage level threshold value configuration may be a threshold value list, including N threshold value configurations, each threshold value corresponding to an enhanced coverage level, and N is a maximum coverage level index value supported by the system. For example, if the maximum coverage level index value supported by the system is 3, the threshold value list configured by the base station includes three threshold value configurations, wherein the threshold value 3 corresponds to the threshold value of the enhanced coverage level 3, and the threshold value 2 corresponds to The threshold of the coverage level 2 is enhanced; the threshold value 1 corresponds to the threshold value of the enhanced coverage level 1.
所述增强覆盖门限值配置可以是基于RSRP的，可选地，其取值范围与系统所支持的RSRP范围一样；此外，所述增强覆盖门限值配置也可以是基于RSRQ的，可选地，其取值范围与系统所支持的RSRQ范围一样。The enhanced coverage threshold value configuration may be based on RSRP. Optionally, the value range is the same as the RSRP range supported by the system. In addition, the enhanced coverage threshold value configuration may also be based on RSRQ. The range of values is the same as the range of RSRQ supported by the system.
图9示出了根据本公开实施例的在用户设备UE处执行的方法900的流程图。方法900用于在UE MAC层执行接入禁止。如图所示，方法900包括以下步骤。FIG. 9 illustrates a flow diagram of a method 900 performed at a user equipment UE, in accordance with an embodiment of the disclosure. Method 900 is for performing access barring at the UE MAC layer. As shown, method 900 includes the following steps.
步骤S910：UE RRC层触发RRC连接建立流程或RRC连接恢复流程，并根据现有标准技术规范(参见技术规范36.331中5.3.3.14章节)执行接入禁止检查。Step S910: The UE RRC layer triggers an RRC connection establishment procedure or an RRC connection recovery procedure, and performs an access prohibition check according to an existing standard technical specification (see section 5.3.3.14 of the technical specification 36.331).
步骤S920：UE RRC层发起RRC连接恢复请求或RRC连接建立请求。Step S920: The UE RRC layer initiates an RRC connection recovery request or an RRC connection establishment request.
上述步骤S910和S920可以认为是可选的。The above steps S910 and S920 can be considered as optional.
步骤S930：当触发了随机接入流程，UE MAC层确定UE的增强覆盖等级。这可以重用现有技术规范(参见标准技术规范TS36.321中5.1.1章节)，也可以采用本公开其他实施例中的UE增强覆盖等级确定方法。Step S930: When the random access procedure is triggered, the UE MAC layer determines the enhanced coverage level of the UE. This can reuse existing technical specifications (see section 5.1.1 of the standard technical specification TS 36.321), and can also employ the UE enhanced coverage level determination method in other embodiments of the present disclosure.
步骤S940：UE MAC层根据与所确定的增强覆盖等级相对应的接入禁止配置执行接入禁止检查。可选地，若接入禁止检查结果为认为接入到该小区是被禁止的，则执行步骤S950。可选地，若接入禁止检查结果不是认为接入到该小区是被禁止的，则执行步骤S960。Step S940: The UE MAC layer performs an access prohibition check according to the access prohibition configuration corresponding to the determined enhanced coverage level. Optionally, if the access prohibition check result is that the access to the cell is prohibited, step S950 is performed. Optionally, if the access prohibition check result is not that the access to the cell is prohibited, step S960 is performed.
步骤S950：UE MAC层通知上层(例如，UE RRC层)接入到该小区是被禁止的。可选地，这个步骤还可以包括停止或放弃正在进行的随机接入过程。Step S950: The UE MAC layer notifies the upper layer (for example, the UE RRC layer) that access to the cell is prohibited. Optionally, this step may also include stopping or abandoning the ongoing random access procedure.
当收到UE MAC层的小区被禁止指示时，UE RRC层认为接入到该小区是被禁止的，或停止/放弃正在进行的RRC流程，并向上层告知本次RRC流程失败。所述RRC流程可以是RRC连接建立流程或RRC连接恢复流程。When receiving the cell prohibition indication of the UE MAC layer, the UE RRC layer considers that access to the cell is prohibited, or stops/abandons the ongoing RRC procedure, and informs the upper layer that the RRC procedure fails. The RRC procedure may be an RRC connection setup procedure or an RRC connection recovery procedure.
步骤S960：如果接入禁止检查的结果指示UE接入到小区不被禁止， 则在随机接入前导码发送次数达到与UE的增强覆盖等级相对应的最大随机接入前导码发送次数的情况下，UE MAC层调整UE的增强覆盖等级，并根据调整后的增强覆盖等级执行另外的接入禁止检查。这个步骤发生在UE增强覆盖等级发生变化时。例如，如果随机接入前导发送次数达到当前UE的增强覆盖等级相对应的最大随机接入前导发送次数，UE MAC层认为UE处于下一个增强覆盖等级；则基于该新确定的UE增强覆盖等级执行步骤S940。Step S960: If the result of the access prohibition check indicates that the UE accesses the cell is not prohibited, if the number of random access preamble transmissions reaches the maximum random access preamble transmission number corresponding to the enhanced coverage level of the UE, The UE MAC layer adjusts the enhanced coverage level of the UE, and performs an additional access barring check according to the adjusted enhanced coverage level. This step occurs when the UE's enhanced coverage level changes. For example, if the number of random access preamble transmissions reaches the maximum random access preamble transmission number corresponding to the current UE's enhanced coverage level, the UE MAC layer considers that the UE is in the next enhanced coverage level; and then performs the UE based on the newly determined UE enhanced coverage level. Step S940.
可选地，需要明确，因为接入禁止检查仅在初始接入时执行，但UE是否处于初始接入，仅能在UE RRC层得知，UE MAC层在执行随机接入过程时并不知道当前随机接入过程是否是处于初始接入。所以，本公开中的一种方法是，UE MAC层从UE RRC层获取需要获知当前随机接入过程是否处于初始接入，即若随机接入流程是由UE RRC层触发的，则UE RRC层会通知通知UE MAC层该随机接入过程是否处于初始接入(即上层是否处于RRC连接建立或RRC连接恢复流程中)，或者该随机接入过程是否需要执行接入禁止检查。在该方法中，只有当UE RRC层指示了该随机接入过程处于初始接入或该随机接入过程需要执行接入禁止检查，UE MAC层才会执行S940。另一种方法是，UE MAC层不需要知道当前随机接入过程是否处于初始接入，当UE RRC层接收到接入该小区被禁止的指示时，若不处于初始接入(即UE RRC层不处于RRC连接建立或RRC连接恢复流程中)，则UE RRC层忽略该指示。Optionally, it needs to be clarified, because the access barring check is only performed during the initial access, but whether the UE is in the initial access, only at the UE RRC layer, the UE MAC layer does not know when performing the random access procedure. Whether the current random access procedure is in initial access. Therefore, a method in the present disclosure is that the UE MAC layer acquires from the UE RRC layer and needs to know whether the current random access procedure is in initial access, that is, if the random access procedure is triggered by the UE RRC layer, the UE RRC layer The UE is notified to inform the UE whether the random access procedure is in the initial access (that is, whether the upper layer is in the RRC connection establishment or the RRC connection recovery procedure), or whether the random access procedure needs to perform the access prohibition check. In this method, the UE MAC layer performs S940 only when the UE RRC layer indicates that the random access procedure is in initial access or the random access procedure needs to perform an access barring check. In another method, the UE MAC layer does not need to know whether the current random access procedure is in initial access. When the UE RRC layer receives the indication that the access to the cell is forbidden, if it is not in the initial access (ie, the UE RRC layer) If not in the RRC connection setup or RRC connection recovery procedure, the UE RRC layer ignores the indication.
下述实施例结合标准技术规范格式对上述步骤中的一些内容进行描述。The following embodiments describe some of the above steps in conjunction with standard technical specification formats.
在一个实施例中，随机接入流程按照下述执行：In one embodiment, the random access procedure is performed as follows:
-清空消息3缓存；- clear the message 3 cache;
-设置随机接入前导发送计数器为1；- Set the random access preamble sending counter to 1;
此处与现有标准技术规范相同，不赘述，可参见标准技术规范TS36.321中5.1.1章节This is the same as the existing standard technical specifications. For details, refer to section 5.1.1 of the standard technical specification TS36.321.
-若上层配置了接入禁止检查配置/参数，执行接入禁止检查；- If the upper layer is configured with the access prohibition check configuration/parameter, the access prohibition check is performed;
-若接入到该小区是被禁止的，- If access to the cell is forbidden,
-告知上层接入到该小区是禁止的，放弃当前随机接入流程。- It is forbidden to inform the upper layer to access the cell, and the current random access procedure is abandoned.
-继续进行随机接入资源的选择。- Continue with the selection of random access resources.
在该实施例中，MAC在选择随机接入资源之前，或者说MAC在发送随机接入前导之前执行基于增强覆盖等级的接入禁止检查。In this embodiment, the MAC performs an enhanced coverage level based access barring check before the random access resource is selected, or the MAC sends a random access preamble.
在一个实施例中，随机接入过程中，MAC层包含下述操作：In one embodiment, during the random access procedure, the MAC layer includes the following operations:
若对于相应的UE增强覆盖等级，If the coverage level is enhanced for the corresponding UE,
PREAMBLE_TRANSMISSION_COUNTER_CE＝PREAMBLE_TRANSMISSION_COUNTER_CE=
maxNumPreambleAttemptCE+1，则重置maxNumPreambleAttemptCE+1, reset
PREAMBLE_TRANSMISSION_COUNTER_CE；若服务小区和UE都支持下一个增强覆盖等级，则认为处于下一个增强覆盖等级，否则，留在当前增强覆盖等级；若认为处于下一个增强覆盖等级，可选地且上层配置了接入禁止检查配置/参数，则执行接入禁止检查。UE MAC层执行接入禁止检查的过程如前面实施例中所述。PREAMBLE_TRANSMISSION_COUNTER_CE; if both the serving cell and the UE support the next enhanced coverage level, it is considered to be in the next enhanced coverage level, otherwise, it remains in the current enhanced coverage level; if it is considered to be in the next enhanced coverage level, optionally and the upper layer is configured If the check-in configuration/parameter is disabled, the access prohibition check is performed. The process in which the UE MAC layer performs an access barring check is as described in the previous embodiment.
在一个实施例中，UE MAC层执行接入禁止检查流程中，UE将：In one embodiment, the UE MAC layer performs an access barring check procedure, and the UE will:
若上层配置了基于增强覆盖等级的接入禁止配置/参数ab-barringCElevel，则若对于UE的增强覆盖等级，其在ab-barringCElevel中对应的bit置为1(或0)，认为接入到该小区是被禁止。另一种描述方式是若上层配置了基于增强覆盖等级的接入禁止配置/参数ab-barringCElevel，则若对于UE的增强覆盖等级，其在ab-barringCElevel中对应的bit置为1(或0)，认为接入到该小区是不被禁止的；否则，认为接入到该小区是被禁止的。If the upper layer is configured with the enhanced coverage level-based access prohibition configuration/parameter ab-barringCElevel, if the enhanced coverage level for the UE is set to 1 (or 0) in the ab-barringCElevel, the access is considered to be The cell is forbidden. Another description is that if the upper layer is configured with an enhanced coverage level-based access prohibition configuration/parameter ab-barringCElevel, if the enhanced coverage level for the UE is set to 1 (or 0) in the ab-barringCElevel corresponding bit. It is considered that access to the cell is not prohibited; otherwise, access to the cell is considered to be prohibited.
在一个实施例中，UE MAC层执行接入禁止检查流程中，UE将：若上层配置了基于增强覆盖等级的接入禁止配置/参数X3，则若UE的增强覆盖等级小于或小于等于X3，则UE认为接入到该小区为禁止的，和/或若UE的增强覆盖等级大于或大于等于X，则UE认为接入到该小区为不被禁止的；反之亦然，若UE的增强覆盖等级小于或小于等于X，则UE认为接入到该小区为不被禁止的，和/或若UE的增强覆盖等级大于或大于等于X，则UE认为接入到该小区为被禁止的。可选地，X3可以理解为最大的接入禁止增强覆盖等级，或最小的接入禁止增强覆盖等级，或最大的不被接入禁止增强覆盖等级，或最小的不被接入禁止增强覆盖等级。In an embodiment, the UE MAC layer performs an access barring check process, and the UE: if the upper layer is configured with an enhanced coverage level-based access barring configuration/parameter X3, if the enhanced coverage level of the UE is less than or equal to X3, The UE considers that access to the cell is prohibited, and/or if the enhanced coverage level of the UE is greater than or equal to X, the UE considers that access to the cell is not prohibited; and vice versa, if the enhanced coverage of the UE If the level is less than or less than or equal to X, the UE considers that access to the cell is not prohibited, and/or if the enhanced coverage level of the UE is greater than or equal to X, the UE considers that access to the cell is prohibited. Optionally, X3 can be understood as the maximum access prohibition enhanced coverage level, or the minimum access prohibition enhanced coverage level, or the largest non-access prohibition enhanced coverage level, or the smallest non-access prohibition enhanced coverage level. .
本公开还提供了一种UE RRC层基于由UE MAC层指示的增强覆盖等 级来执行接入禁止的方法。该方法与在UE RRC层执行的接入禁止方法类似，并且还可以包括下述实施例。The present disclosure also provides a method in which a UE RRC layer performs access barring based on an enhanced coverage level indicated by a UE MAC layer. The method is similar to the access barring method performed at the UE RRC layer, and may also include the following embodiments.
在一个实施例中，若在随机接入过程中，UE MAC层认为UE处于下一个增强覆盖等级，UE MAC层向上层指示所确定的增强覆盖等级。UE RRC层若收到UE MAC层所指示的UE增强覆盖等级，则UE RRC层根据该增强覆盖等级执行基于增强覆盖等级的接入禁止检查。若检查结果为接入该小区不被通过，则告知UE MAC层放弃正在进行的随机接入流程，并结束正在进行的RRC连接建立流程或RRC连接恢复流程。在接收到UE RRC层的放弃指示之后，UE MAC层放弃正在进行的随机接入流程。In an embodiment, if the UE MAC layer considers the UE to be in the next enhanced coverage level during the random access procedure, the UE MAC layer indicates the determined enhanced coverage level to the upper layer. If the UE RRC layer receives the UE enhanced coverage level indicated by the UE MAC layer, the UE RRC layer performs an access prohibition check based on the enhanced coverage level according to the enhanced coverage level. If the result of the check is that the access to the cell is not passed, the UE is notified to the MAC layer to abandon the ongoing random access procedure, and the ongoing RRC connection establishment procedure or the RRC connection recovery procedure is ended. After receiving the abandonment indication of the UE RRC layer, the UE MAC layer relinquishes the ongoing random access procedure.
可选地，在该实施例中，UE MAC层可以在向上层指示所确定的增强覆盖等级后，停止当前正在进行随机接入过程，直到收到上层的确认指示。该确认指示用于告知UE MAC层继续进行随机接入流程。同理，UE RRC层在接收到UE MAC层上报的所确定的增强覆盖等级后，若基于增强覆盖等级的接入禁止检查结果为接入到本小区不被禁止，则UE RRC层向下层发送确认指示，指示下层继续挡墙正在进行的随机接入流程。Optionally, in this embodiment, after the upper layer indicates the determined enhanced coverage level, the UE MAC layer may stop the random access procedure currently being performed until an upper layer confirmation indication is received. The acknowledgment indication is used to inform the UE that the MAC layer continues the random access procedure. Similarly, after receiving the determined enhanced coverage level reported by the UE MAC layer, the UE RRC layer sends the UE RRC layer to the lower layer if the access restriction check result based on the enhanced coverage level is that the access to the local cell is not prohibited. A confirmation indication instructs the lower layer to continue the random access process in progress of the retaining wall.
