FIG. 2 is a flowchart of a method for updating a notification area according to an exemplary embodiment. As shown in FIG. 2, the method is used in a base station, and includes the following steps.

In step 201, the first notification area update request sent by the user equipment UE is received, where the first notification area update request carries the first cell identifier and the access base when the notification area update is last performed. The base station identifier of the station, where the first cell identifier is a cell identifier that is currently updated by the notification area.

When the cell corresponding to the first cell identifier does not currently allow access by the UE, it is determined that the update notification is rejected to the UE.

Optionally, the method further includes:

When the UE is in an inactive state, and the data packet is currently transmitted between the UE and the UE, the specified signaling is sent to the UE, where the designated signaling carries the fourth cell identifier of the current notification area. The specified signaling is used to indicate that the UE updates the notification area to the cell corresponding to the fourth cell identifier.

FIG. 3 is a flowchart of a method for updating a notification area according to an exemplary embodiment. As shown in FIG. 3, the method includes the following steps.

In step 301, when the UE is in an inactive state, it determines, according to the stored cell identifier list, a first cell identifier that is currently updated by the notification area, where the cell identifier list stores multiple cell identifiers and corresponding to each cell identifier. The current signal strength of the cell.

The operation of determining, by the UE, the first cell identifier that is currently performing the notification area update may include the following two manners.

In the first mode, when the UE detects the second cell identifier, and the second cell identifier is different from the area identifier of the currently located notification area, it is determined whether the second cell identifier exists in the cell identifier list; When the second cell identifier exists, the cell identifier with the highest signal strength is selected from the cell identifier list; and the selected cell identifier is determined as the first cell identifier that is currently performing the notification region update.

It should be noted that the cell involved in the embodiment of the present disclosure is obtained by dividing a coverage area of a base station network. A base station may include one or several cells, and each cell is assigned an identifier for uniquely identifying a corresponding cell.

In addition, the cell identifier list is obtained by the UE from the base station, that is, the UE may receive the cell identifier list broadcast by the base station in the currently located cell, where the multiple cell identifiers stored in the cell identifier list are The identifier of all the cells in the base station; or the UE receives the cell identifier list configured by the base station for the UE, and the multiple cell identifiers stored in the cell identifier list are identifiers of the cells selected by the base station from all the cells.

It should be noted that when the base station configures the cell identifier list for the UE, the base station may configure the same cell identifier list for each UE in the coverage area, or may configure different cell identifier lists, and the base station may page to one. The UE configures a cell identity list for the UE, and sends the cell identity list to the UE.

Further, when the second cell identifier does not exist in the cell identifier list, the UE may determine whether the signal strength of the cell corresponding to the second cell identifier is greater than or equal to a preset strength threshold, and determine a signal of the cell corresponding to the second cell identifier. Whether the strength is greater than each cell mark in the cell identifier list Know the signal strength of the corresponding cell. When the signal strength of the cell corresponding to the second cell identifier is greater than or equal to the preset strength threshold, and the signal strength of the cell corresponding to the second cell identifier is greater than the signal strength of the cell corresponding to each cell identifier in the cell identifier list. And determining, by the second cell identifier, a first cell identifier that is currently performing the notification area update.

It should be noted that the preset intensity threshold may be set in advance. For example, the preset intensity threshold may be 60 db (decibel), 70 db, or the like.

In addition, when the signal strength of the cell corresponding to the second cell identifier is less than the preset strength threshold, or the signal strength of the cell corresponding to the second cell identifier is smaller than the signal strength of the cell corresponding to any cell identifier in the cell identifier list, The UE may abandon the update operation of the current notification area, and delete the context, and switch from the inactive state to the idle state.

In the second mode, when the update time of the periodic update notification area configured by the UE arrives, the cell identifier with the highest signal strength is selected from the cell identifier list; and the selected cell identifier is determined as the first cell currently performing the notification area update. Logo.

It should be noted that the base station may configure an update period of the notification area for the UE, and the update period may be 1 day, 2 days, and the like.

It should be noted that when the cell identifier with the highest signal strength selected by the UE is the same as the area identifier of the notification area currently located, the UE will not initiate an operation of notifying the area update.

In step 302, the UE sends a first notification area update request to the base station, where the first notification area update request carries the first cell identifier and the base station identifier of the visited base station when the notification area update was last performed.

It should be noted that the base station identifier is used to uniquely identify the base station that is accessed when the UE performs the notification area update last time, and the base station identifier may be the IP (Internet Protocol, MAC) of the base station (Media Access Control). , media access control) and more.

In addition, in order to facilitate the subsequent UE to continue the update operation of the notification area, the first notification area update request may not only carry the first cell identifier and the base station identifier of the visited base station when the notification area update was last performed, the first notification The area update request may further include an identifier detection list, where the identifier detection list includes a cell identifier and a corresponding signal strength of all the cells detected by the UE, and in the actual application, the identifier detection list may also include the UE detecting The cell identity of the partial cell with strong signal strength and the corresponding signal strength.

It should be noted that, in order to ensure that the UE can successfully send the first notification area update request to the base station to avoid the influence of other data, the UE may hang when sending the first notification area update request. Signaling bearer and data bearer.

In step 303, the base station receives a first notification area update request sent by the UE.

In step 304, when the identifier of the base station is different from the identifier of the base station, the base station acquires the context of the UE from the base station corresponding to the base station identifier.

Since the context of the UE includes information such as network capability, authentication information, negotiated security algorithm, generated key, created connection information, UE's IP, and the like. The information is an important basis for the base station to process the UE. When the base station cannot know the context of the UE, the base station cannot know the PGW (PDN Gate Way) connected by the UE, the bearer created by the UE, and the like. The base station cannot process the request sent by the UE. Therefore, in order to ensure that the base station can process the notification area update request sent by the UE, the base station needs to acquire the context of the UE from the base station corresponding to the base station identifier.

After obtaining the context of the UE, the base station may determine whether the number of UEs currently accessed by the cell corresponding to the first cell identifier is greater than or equal to a preset number, and the number of UEs currently accessed by the cell corresponding to the first cell identifier. When it is greater than or equal to the preset number, it is determined to send a reject update notification to the UE; or, when the cell corresponding to the first cell identifier does not currently allow access by the UE, it is determined to send a reject update notification to the UE.

It should be noted that the preset number may be set in advance, for example, the preset number may be 100, 200, and the like.

In addition, when the cell corresponding to the first cell identifier currently allows the access of the UE, and the number of UEs currently accessed by the cell corresponding to the first cell identifier is less than a preset number, determining to send the reject update notification to the UE and The operation of allowing the update notification is sent in step 305 described below. The permission notification update is used to indicate that the UE performs the update of the notification area based on the first cell identifier, and the permission notification update may carry information such as a new UE status identifier, a new security key, and the like allocated to the UE.

In a possible implementation, after the base station acquires the context of the UE from the base station corresponding to the base station identifier, the base station may send a reject update notification to the UE based on the context of the UE and the first cell identifier, and reject the update notification carrying the rejection. And a recommendation identifier list, where the recommendation identifier list stores a cell identifier that is recommended for the UE to perform the notification area update; the UE receives the rejection update notification sent by the base station, and selects from the recommended identifier list according to the preset reselection rule. a cell identifier, the selected cell identifier is determined as a third cell identifier; and the second notification area update request is sent to the base station, where the second notification area update request carries the third cell identifier and the visited base station when the notification area update is performed last time Base station identity; the base station receives a second notification area update request sent by the UE; when the base station When the identifier is different from the identifier of the UE, the context of the UE is obtained from the base station corresponding to the identifier of the base station; and the reject update notification is sent to the UE based on the context of the UE and the third cell identifier. When the UE receives the rejection update notification sent by the base station again, the UE returns to perform the step of selecting a cell identifier from the recommended identifier list according to the preset reselection rule, and determining the selected cell identifier as the third cell identifier. The base station returns to perform the step of receiving the second notification area update request sent by the UE.

The information about the IP of the UE may be included in the context of the UE. Therefore, the base station may send a rejection update notification to the UE based on the IP of the UE carried in the context of the UE.

It should be noted that the preset reselection rule is used to select a cell identifier from the recommended identifier list, and the preset reselection rule may be set in advance. For example, the preset reselection rule may be as large as the signal strength. Selecting a cell identifier in a small order may also select a cell identifier or the like in order from the top to the bottom of the cell identifier in the suggested identifier list.

It is to be noted that, when the UE sends the first notification area update request to the base station, the first area update request may further carry the identifier detection list. Therefore, the recommended identifier list sent by the base station to the UE may include the base station from the identifier. Detecting all cell identifiers and corresponding signal strengths obtained in the list, or including partial cell identifiers and corresponding signal strengths obtained from the identifier detection list.

In another possible implementation manner, when the base station cannot obtain the context of the UE from the base station corresponding to the base station identifier, the base station may directly send a reject update notification to the UE.

In another possible implementation, the base station may obtain not only the context of the UE but also the historical cell list in which the UE resides, and the base station may be in the historical cell list in which the UE resides. The cell identifier is determined, and the historical trajectory of the UE is determined, and the next mobile cell of the UE is predicted according to the historical trajectory of the UE. When the base station predicts the cell identity of the next mobile cell and the area identifier of the currently notified area is not At the same time, the rejection update notification sent to the UE.

In another possible implementation manner, when the refusal update notification sent by the base station to the UE carries the refusal update reason, but does not carry the recommended identifier list, the UE may abandon the current notification area when receiving the refusal update notification. Update and delete the context of the UE, switching from the inactive state to the idle state.

Furthermore, in order to prevent the UE from repeatedly transmitting the same notification area update request to the base station, the UE wastes the resource, and after the UE sends the second notification area update request to the base station, the UE may also count the number of times the second notification area update request is sent; When the number of transmissions is greater than or equal to the preset number of times threshold, the context of the UE is deleted, and the inactive state is switched to the idle state.

It should be noted that the preset number threshold may be set in advance, for example, the preset number threshold may be Thought 5 times, 6 times, and so on.

In step 305, the base station sends an allow update notification to the UE based on the context of the UE and the first cell identity.

The base station may include the connection information created by the UE, the IP address of the UE, and the like, and the base station may send an allow update notification to the UE based on the IP of the UE carried in the context.

In step 306, the UE receives the permission update notification sent by the base station, and updates the notification area to the cell corresponding to the first cell identifier.

After the UE updates the notification area to the cell corresponding to the first cell identifier, the UE may further send an update completion notification to the base station. When the base station receives the update completion notification sent by the UE, the UE determines that the UE notification area update is complete. It should be noted that when the new security key is carried in the allowed update notification received by the UE, the UE may send an update completion notification to the base station by using the new security key to ensure the security of communication between the UE and the base station. .

In addition, when the UE is a periodic update notification area, after the UE updates the notification area to the cell corresponding to the first cell identifier, the UE may restart the timer of the periodic update notification area.

Further, after the UE updates the notification area to the cell corresponding to the first cell identifier, and detects that the update of the notification area is not performed within the specified duration after the update of the notification area, the UE deletes the context of the UE, and is inactive. Switch to the idle state. The specified duration can be set in advance, for example, the specified duration can be 1 day, 2 days, and the like.

In addition, since the UE is inactive for a long time or wastes power consumption of the UE, the UE may delete the context of the UE when detecting that the update of the notification area is not performed within a specified duration after the update of the notification area, and Switch from inactive to idle.

It is to be noted that the UE may perform the update of the notification area not only when determining the identity of the first cell, but also the update of the notification area when the UE receives the specified signaling. That is, when the UE is in an inactive state, and the base station is currently transmitting the data packet with the UE, the base station may send the specified signaling to the UE, where the designated signaling carries the fourth cell identifier of the current notification area. The specified signaling is used to indicate that the UE updates the notification area to the cell corresponding to the fourth cell identifier. The UE receives the specified signaling, and updates the notification area to the cell corresponding to the fourth cell identifier.

In the embodiment of the present disclosure, when the UE is in an inactive state, the data packets transmitted between the UE and the base station are small data packets, that is, data packets whose transmission size is smaller than a preset size. The preset size may be set in advance. For example, the preset size may be 5 MB (megabytes), 10 MB, or the like.

In the embodiment of the present disclosure, the UE may determine the first cell identifier by using the stored cell identifier list, and perform update of the notification area according to the first cell identifier, thereby implementing a change of the notification area where the UE is in an inactive state. At the time, the update operation of the notification area can be performed. In addition, when the base station refuses to update the UE by using the first cell identifier, if the refusal update notification carries the recommended identifier list, the UE may further update the notification area according to the cell identifier in the suggested identifier list, thereby improving the notification. The reliability of the area update. In addition, when the UE detects the second cell identifier in the inactive state, if the signal strength of the corresponding cell is less than the preset strength threshold, or the signal strength of the cell corresponding to the second cell identifier is smaller than the cell identifier list. When any cell identifies the signal strength of the corresponding cell, the UE may abandon the update operation of the current notification area, thereby avoiding unnecessary notification area update, and improving the efficiency of updating the notification area.
