Method, system and device for mobility management The application is submitted to the Chinese Patent Office on November 10, 2011, the application number is 201110355805.4, and the invention name is

The priority of the Chinese Patent Application, which is incorporated herein by reference. Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a method, system and device for mobility management. Background technique

Mobility management refers to a series of operations in which a user equipment switches to a resident or working cell during the mobile process, including the operation of the network and the user equipment. These operations ensure that the user equipment is in a better wireless signal coverage, ensuring continuity of the service and enabling the user to have a better experience. Common mobility management operations include cell reselection and cell handover. The cell reselection is a resident cell change of the user equipment in an idle state, and the cell handover is a work cell change in which the user equipment operates in a connected state. For cell reselection, the network side does not participate, and the user equipment measures the neighboring cell signal and has certain criteria to determine whether to reselect the cell with better signal. For cell handover, it is mainly dominated by the network side. After the user equipment measures the neighboring cell signal, it reports it according to the regulations. The network determines whether to switch and which cell to switch to.

Machine-to-machine (M2M) communication is a new communication concept. Its purpose is to combine many different types of communication technologies, such as: machine-to-machine communication, machine control communication, human-computer interaction communication, Mobile internet communication to promote social production and lifestyle development. It is expected that the business of human-to-human communication in the future may only account for 1/3 of the entire user equipment market, and a larger amount of communication is the inter-machine communication service.

In the LTE (Long Term Evolution) system, a neighboring cell refers to a cell that is geographically adjacent. It is assumed that the base station 1 manages a large number of cells (cell 1, cell 2, cell 3, cell 4, etc.), and the base station 2 also manages some cells (cell 5, cell 6, cell 7, etc.), and cell 1 and cell 2 are neighboring cells, and belong to the same base station. 1 management; cell4 and cell 5 are also neighbors, but cell 4 belongs to base station 1 management, and cell 5 belongs to base station 2 management.

For the configuration of the neighboring area, there are currently two methods: One is configured by the OM (operating maintenance) module. The OM module obtains the neighboring area information of a certain cell by manual measurement or according to the cell plan, and then allocates the information to the base station; the other is measured by the user equipment and reported to the base station, and the base station obtains the cell through the measurement information of many user equipments in a certain cell. Neighborhood information.

In the standard evolution process, with the introduction of new features in later versions, the previous version of the device obviously does not support these new features introduced later. For some features, if the previous network device does not support it, then support for new features. The device may not work in the cell managed by the network device.

For example, for MTC (Machine Type Communications) devices that support small bandwidth, it is not possible to work in a network that does not support small bandwidth. When the user equipment works in an idle (free) state or a connected state in a small bandwidth-supported network, it is always in accordance with SIB (System Information Block) or dedicated RRC (Radio Resource Control) signaling. The configured neighbor list is used for the evaluation of cell reselection and the measurement of cell handover. According to the current protocol, the base station cannot know whether the cell managed by the neighboring base station supports small bandwidth, and therefore cannot provide such information when configuring the neighbor list. In this way, the small-bandwidth user equipment cannot know which neighboring cells are cells supporting small bandwidth/cells that do not support small bandwidth, which may cause blind measurement, resulting in power consumption, and even causing cell reselection failure. In the scenario of the connection state, in the scenario of handover between the base stations, the source base station does not know which cells of the target base station are cells supporting small bandwidth/cells that do not support small bandwidth, and may cause a problem that the source base station determines the handover target cell. When the small bandwidth user equipment is switched to a network that does not support small bandwidth, the user equipment cannot work.

In summary, in the current M2M communication, the base station cannot know whether the cell managed by the neighboring base station supports the new feature for the neighboring cell under the jurisdiction of different base stations. In the scenario of the connection state, the source base station does not know whether the cell of the target base station supports the new feature. Summary of the invention

In the embodiment of the present invention, the network side device can notify each other of the capability of the cell managed by the network, so that the base station can know whether the target cell supports the new feature in the M2M communication. . Further, the base station can know which cells support the new feature, so that after the user equipment reports the handover candidate cell, the cell supporting the new feature can be preferentially switched.

The capability of the cell in the embodiment of the present invention is used to indicate whether the cell supports some or some characteristics, including but not limited to one of the following capabilities:

Whether to support MIMO (multple input multiple output), whether to support high-order modulation, whether to support multi-carrier data transmission, whether to support carrier aggregation, whether to support data transmission with a maximum bandwidth smaller than the maximum bandwidth supported by user equipment, and whether it supports The MTC device access with the maximum bandwidth smaller than the maximum bandwidth supported by the user equipment.

The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 , the method for performing mobility management between network-side devices in the embodiment of the present invention includes the following steps: Step 101: The first network-side device determines a capability for indicating a cell managed by the first network-side device or is used for First notification information indicating capabilities of the first network side device;

Step 102: The first network side device sends the first notification information.

Step 103: The second network side device receives the first notification information.

Step 104: The second network side device resides in the first notification information to determine the capability of the cell managed by the first network side device. If the first network side device and the second network side device both have a station, in step 102, the first network side is set. The first notification information is sent through the X2 interface. Correspondingly, in step 103, the second network side device receives the first notification information through the X2 interface.

The X2 interface is an interface between base stations, and performs user data transmission, user data, and signaling processing between base stations. If the first network side device and the second network side device are RNCs (Radio Network Controllers), the first network side device sends the first notification information through the Iur interface in step 102;

In 103, the second network side device receives the first notification information by using an Iur interface.

The Iur interface is an interface between RNCs, which performs user data transmission between RNCs, processing of user data and signaling, and the like.

Correspondingly, in step 103, the second network side device receives the first notification information through the 0M interface.

In step 101, if the first notification information determined by the first network side device is the first notification information indicating the capability of the first network side device, in step 104, the second network side device determines the first network side device. By being able to support a certain capability, it can be determined that all cells managed by the first network side device support the capability.

Preferably, the first notification information may be any information capable of representing capabilities, and three types of information are listed below.

1. The first notification information is a capability configuration parameter (the capability configuration parameter is other configuration parameters related to supporting the capability). For example, it may be a parameter of a physical layer or a high-level parameter necessary to support the capability. It is assumed that the notification supports the data transmission whose maximum bandwidth is smaller than the standard maximum bandwidth. If supported, the information transmitted may be the corresponding special control channel parameter configuration; correspondingly, after receiving the receiver, the sender knows that the sender supports the capability. .

Specifically, the first network side device determines a capability configuration parameter corresponding to the capability that the cell managed by the first device can support, or a capability configuration parameter corresponding to the capability that can be supported by the device.

Correspondingly, the second network side device can determine the corresponding capability according to the capability configuration parameter.

Second, the first notification information is the version number corresponding to the capability.

Specifically, the first network side device receives the correspondence between the version number and the capability according to a preset (for example, if the capability is specified in a protocol whose protocol version number is R11, and if the protocol version number is R11, the receiving The end determines the capability specified by the sender to support the R11 protocol, and determines the version corresponding to the capability that the managed cell can support. Number or the version number corresponding to the capability that it can support;

Correspondingly, the second network side device determines the capability corresponding to the received version number according to the preset relationship between the version number and the capability.

The first notification information is capability indication information (ie, an indication of whether the capability is supported, and may be an enumeration value, for example, if supported, the enumeration value is set to "supported"; or a boolean value For example, if it is supported, set the corresponding capability indication information to TRUE, otherwise set to FALSE).

Specifically, the first network side device is capable of supporting the capability that the self-managed cell can support or the capability that can be supported by itself, and generating the capability indication information;

Correspondingly, the second network side device is in the capability indication information, and determines the capability of the cell managed by the first network side device. Preferably, the capability of the cell in the embodiment of the present invention includes whether the MTC device access with the maximum bandwidth less than the maximum bandwidth supported by the user equipment is supported.

Preferably, the maximum bandwidth supported by the user equipment is 20 MHz.

The second notification information is specific content of the capability indication information. For reference, the first notification information is specific content of the capability indication information.

The network side device can notify the user equipment of the neighboring cell, so that the user equipment can only detect the neighboring cell that can support the new feature, so that the user equipment supporting the new feature can perform the cell reselection and handover of the mobility process normally, and the data transmission is performed. It will not be interrupted; it can also reduce the workload of user equipment measurement and achieve power saving.

In the implementation, if the neighboring cell is a cell managed by the network side device, the network side device can directly determine the capability of the neighboring cell; if the neighboring cell is a cell managed by another network side device, the network side device needs to first cooperate with other networks. The side device interacts to obtain the capability of the neighboring cell, and the specific interaction mode may use the interaction mode of the embodiment of the present invention in FIG. The same, you can also use other interaction methods.

Preferably, the capability of the cell in the embodiment of the present invention includes whether the MTC device access with the maximum bandwidth less than the maximum bandwidth supported by the user equipment is supported.

Preferably, the maximum bandwidth supported by the user equipment is 20 ΜΗζ.

As shown in FIG. 3, the method for the user equipment to receive the notification of the network side device in the embodiment of the present invention includes the following steps: Step 301: The user equipment receives a second notification message from the network side device for indicating the capability of the neighboring cell of the user equipment. ;
