Description

Tracking area update method and device

technical field

The present application relates to the technical field of communications, and in particular to a method and device for updating a tracking area.

Background technique

In order to manage the location of a user equipment (User Equipment, UE), a long term evolution (Long Term Evolution, LTE) system introduces a new concept—tracking area (Tracking Area, TA). Each tracking area has a unique tracking area identifier (Tracking Area Identifier, TAI), and each tracking area may be composed of cells under one or more evolved base stations (evolved Node B, eNB).

Since the coverage of each tracking area is limited, when the UE moves out of the coverage of the currently configured tracking area, the UE needs to initiate a tracking area update (Tracking Area Update, TAU) request to notify the MME (Mobility Management Entity, Mobile management entity) to update the tracking area of the UE. Frequent tracking area update process will increase the signaling load of the network, resulting in waste of wireless side and core network resources. Therefore, in order to optimize UE mobility management, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) introduces the concept of Tracking Area list (TA list), when UE moves from the coverage area of a tracking area list When the coverage of another tracking area list is reached, the tracking area update process needs to be executed. Since a tracking area list includes at least one tracking area, the coverage of the tracking area list is larger than the tracking area, thereby reducing the tracking area update frequency of the UE.

However, when the MME configures the tracking area list for the UE, the MME needs to calculate a tracking area list suitable for the UE, and the above calculation process will occupy computing resources of the MME. In a scenario with a large number of users, the calculation process of configuring the tracking area list for each UE will occupy a large amount of computing resources of the MME, affecting the normal operation of the MME.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

In order to solve the problem that the calculation process of configuring the tracking area list for each UE occupies a large amount of computing resources of the MME and affects the normal operation of the MME in a scenario with a large number of users, an embodiment of the present application provides a tracking area update method. As shown in Figure 1, the method includes:

101. The MME receives a tracking area update request sent by the UE.

Specifically, when the UE moves out of the coverage of the current tracking area or tracking area list, the UE sends a tracking area update request to the eNB, and the eNB forwards the tracking area update request to the MME.

102. The MME detects whether the calculation load is less than or equal to a first preset value.

Wherein, the computing load is a ratio of computing resources currently used by the MME to total computing resources.

It should be noted that if the calculation load is less than or equal to the first preset value, it means that the remaining available computing resources of the MME are relatively sufficient, even if the MME will occupy a part of the computing resources when configuring the tracking area list for the UE, it will not affect the normal operation of the MME . If the calculation load is greater than the first preset value, it indicates that the remaining available calculation resources of the MME are insufficient. In this case, configuring the tracking area list for the UE by the MME may cause the MME to fail to work normally. Therefore, if the calculation load is less than or equal to the first preset value, step 103 is directly performed. If the calculation load is greater than the first preset value, step 104 is directly performed.

103. The MME configures a tracking area list for the UE.

In a specific implementation process, the MME acquires the tracking area corresponding to the current location of the UE from the tracking area update request. The MME counts the frequency of occurrence of the UE in different tracking areas, selects a tracking area whose occurrence frequency is greater than a preset threshold, and generates a new tracking area list from the selected tracking area corresponding to the current location of the UE. The MME sends tracking area update request response information to the UE, and the tracking area update request response information carries a new tracking area list.

It should be noted that, the tracking area list generation method involved in the embodiment of the present application may also refer to the tracking area list generation method in the prior art, which will not be repeated here.

104. The MME configures a tracking area for the UE.

In the specific implementation process, the MME obtains the tracking area corresponding to the current location of the UE from the tracking area update request, and the MME sends the tracking area update request response information to the UE, and the tracking area update request response information carries the corresponding tracking area corresponding to the current location of the UE. tracking area

In the tracking area update method provided by the embodiment of the present application, after receiving the tracking area update request from the UE, the MME detects whether the calculation load is less than or equal to the first preset value, and the calculation load is the calculation resources currently used by the MME and the total calculation resources ratio. If the calculation load is less than or equal to the first preset value, it means that the remaining available computing resources of the MME are relatively sufficient. Even if the MME will occupy a part of the computing resources when configuring the tracking area list for the UE, it will not affect the normal work of the MME. Therefore, the MME can provide The UE configures a tracking area list. If the calculation load is greater than the first preset value, it indicates that the remaining available calculation resources of the MME are insufficient. In order to avoid affecting the normal operation of the MME, the MME configures a tracking area for the UE. The tracking area update method provided by this application adaptively configures the tracking area list or tracking area for the UE according to the actual situation of MME computing resources, so as to avoid the occupation of the calculation process of configuring the tracking area list for all UEs in the scenario of large users The massive computing resources of the MME affect the normal work of the MME.

The MME configures the tracking area list for the UE to prevent the UE from frequently triggering the tracking area update request due to location movement, but some UEs do not move frequently, so the tracking area update request is rarely triggered. The MME configures the tracking area list for the UE whose location does not move frequently, which is actually a waste of computing resources of the MME. In order to avoid this situation, the embodiment of the present application provides another method for updating the tracking area. As shown in Figure 2, the method includes:

201. The MME receives a tracking area update request sent by the UE.

202. The MME detects whether the calculation load is less than or equal to a first preset value.

In a specific implementation process, if the calculation load is less than or equal to the first preset value, step 203 to step 205 are directly executed. If the calculation load is greater than the first preset value, step 207 is directly performed.

203. The MME obtains the historical tracking area update request of the UE.

Wherein, the historical tracking area update request is a tracking area update request sent by the UE within the first preset time. The first preset time can be adjusted according to actual conditions, for example, the first preset time can be one hour, four hours or twenty-four hours before the current moment.

In the specific implementation process, a tracking area database is established on the MME or other network equipment. The tracking area database is used to store the tracking area update requests sent by all UEs. The MME retrieves the UE from the tracking area database according to the identifier of the UE. History tracking area update requests for .

204. The MME determines the mobility characteristic parameter of the UE according to the historical tracking area update request of the UE.

Wherein, the mobility characteristic parameter is used to indicate the frequency at which the UE triggers a tracking area update request due to location movement.

In the specific implementation process, the tracking area database involved in step 203 is also used to store the time corresponding to each time the UE sends a tracking area update request. Therefore, the MME determines that the UE is at the first preset time according to the historical tracking area update request of the UE. The time corresponding to each tracking area update request sent. The MME determines the average time interval for the UE to send the tracking area update request for the previous N times according to the time corresponding to each time the UE sends the tracking area update request within the first preset time in, Indicates the average time interval for the UE to send the tracking area update request for the first N-1 times, and n represents Occupied weight, U[N] represents the time interval between the Nth tracking area update request and the N-1th tracking area update request, and N represents the total number of times the UE sends the tracking area update request within the first preset time . at this time, The unit is minutes. The average time interval for the MME to send the tracking area update request according to the previous N times of the UE determining the mobility characteristic parameter U _M of the UE, At this time, the unit of U _M is: times/hour.

Exemplarily, the UE sends a total of 5 tracking area update requests, n=1/3, the average time interval between the first 4 sending tracking area update requests is 20 minutes, and the time between the fifth and fourth tracking area update requests interval is 30 minutes, so Minutes, the mobility characteristic parameters of the UE

Or, the MME determines the time T1 corresponding to the first tracking area update request sent by the UE within the _first preset time and the time T corresponding to the last tracking area update request sent by the UE according to the historical tracking area update request of the UE _N , and count the total number N of tracking area update requests sent by the UE within the first preset time, through the formula Determine the mobility characteristic parameter U _M of the UE.

205. The MME detects whether the mobility characteristic parameter of the UE is greater than or equal to a second preset value.

Wherein, the second preset value may be an average value of mobility characteristic parameters of all UEs managed by the MME.

It should be noted that if the mobility characteristic parameter of the UE is greater than or equal to the second preset value, it means that the tracking area update request frequency triggered by the UE due to location movement is relatively high. In order to avoid frequent tracking area update procedures from increasing the signaling load of the network, the MME A tracking area list should be configured for the UE. If the mobility characteristic parameter of the UE is less than the second preset value, it means that the tracking area update request frequency triggered by the UE's location movement is low. In order to avoid wasting computing resources of the MME, the MME should configure a tracking area for the UE. Through the above analysis, if the mobility characteristic parameter of the UE is greater than or equal to the second preset value, step 206 is directly executed; if the mobility characteristic parameter of the UE is smaller than the second preset value, step 207 is directly executed.

206. The MME configures a tracking area list for the UE.

207. The MME configures a tracking area for the UE.

In the tracking area update method provided in the embodiment of the present application, when the calculation load is less than the first preset value, the MME determines the mobility characteristic parameters of the UE according to the historical tracking area update request of the UE. When the mobility characteristic parameter is greater than or equal to the second preset value, it indicates that the location of the UE moves frequently, so the MME configures a tracking area list for the UE. When the mobility characteristic parameter is smaller than the second preset value, it means that the UE does not move frequently, so the MME configures a tracking area for the UE, thereby saving computing resources of the MME.

When the MME initiates paging to the UE, all eNBs in the tracking area/tracking area list corresponding to the UE will send a paging request to establish a connection with the UE. Therefore, the tracking area/tracking area list corresponding to the UE determines the paging scope initiated by the MME. The larger the range, the heavier the signaling load on the network. Therefore, when the MME updates the tracking area for the UE, it needs to take into account the paging characteristics of the UE, so as to avoid excessive signaling load affecting the normal operation of the communication network. Considering this situation, this embodiment of the present application provides another tracking area update method. As shown in Figure 3, the method includes:

301. The MME receives a tracking area update request sent by the UE.

302. The MME detects whether the calculation load is less than or equal to a first preset value.

Specifically, if the calculation load is greater than the first preset value, step 303 is directly performed; if the calculation load is less than or equal to the first preset value, steps 304 to 308 are directly performed.

303. The MME configures a tracking area for the UE.

304. The MME acquires the historical tracking area update request of the UE.

305. The MME determines the mobility characteristic parameter of the UE according to the historical tracking area update request of the UE.

306. The MME acquires the number of times the UE is paged within a second preset time.

Wherein, the second preset time can be adjusted according to actual conditions, for example, the second preset time can be one hour, four hours or twenty-four hours before the current moment.

Specifically, a paging database is established on the MME or other network equipment, and the paging database is used to store data of all UEs being paged. According to the identifier of the UE, the MME retrieves the paged data of the UE from the paging database. The MME counts the number of times the UE is paged within the second preset time according to the paged data of the UE.

307. The MME determines the paging characteristic parameter of the UE according to the number of times the UE is paged within the second preset time.

Wherein, the paging characteristic parameter is used to indicate the frequency at which the UE is paged.

Specifically, the calculation formula of the paging characteristic parameter is: Wherein, UP represents a paging characteristic parameter, M represents the number of times of being paged, and _T represents the time length of the second preset time. For example, if the UE is paged 12 times within 2 hours, the paging characteristic parameter of the UE is 6 times/hour.

In addition, steps 304, 305 and steps 306, 307 do not have a difference in execution steps, that is, in the specific implementation process, steps 304, 305 can be executed first, and then steps 306, 307 can be executed; or, steps 306, 307 can be executed first. 307, execute steps 304 and 305 again.

308. The MME determines an update mode according to the paging characteristic parameter and mobility characteristic parameter of the UE.

Wherein, the update mode includes a tracking area mode and a tracking area list mode; the tracking area mode indicates that the MME configures a tracking area for the UE; the tracking area list mode indicates that the MME configures a tracking area list for the UE.

In the specific implementation process, _UM represents the mobility characteristic parameter of the UE, _UP represents the paging characteristic parameter of the UE, α represents the adjustment factor of the mobility characteristic parameter, and β represents the adjustment factor of the paging characteristic parameter, and E( U _M ) represents the average value of the mobility characteristic parameters of all UEs managed by the MME, and E( _UP ) represents the average value of the paging characteristic parameters of all UEs managed by the MME. If _{αU M -βUP} ≥ αE(UM ) _-βE (UP ), it means that compared with the signaling load caused during the paging process, the signaling load caused by the UE in the tracking area update process is heavier. Therefore, the MME selects a tracking area list mode, and configures a tracking area list for the UE. If _{αU M -βUP} <αE(UM ) _-βE (UP ), it means that the signaling load caused by the UE during the paging process is heavier than the signaling load caused during the tracking area update process. Therefore, the MME selects a tracking area mode, and configures a tracking area for the UE.

In the tracking area update method provided by the embodiment of the present application, when the calculation load is less than the first preset value, the MME determines the paging characteristic parameter and the mobility characteristic parameter of the UE, and according to the paging characteristic parameter and the mobility characteristic parameter of the UE, The mobility characteristic parameter determines to configure a tracking area or a tracking area list for the UE. In the process of configuring the tracking area or tracking area list for the UE, the MME takes into account the UE's mobility characteristics and paging characteristics, thereby reducing the signaling load of the network.
