Description

Method and system for migrating UE state

The present invention relates to the field of wireless network communication, and in particular, to a method and system for migrating the state of a user equipment (User Equipment, UE for short). BACKGROUND With the development of mobile communication technologies, wireless Internet is exploding, and wireless network load is becoming heavier. Operators are eager to reduce network load and improve utilization of wireless network resources while ensuring user experience. In addition, the competition among wireless network operators is becoming more and more fierce. Wireless network operators need to improve the user experience of wireless Internet services as much as possible, and reduce the off-network rate. The Universal Mobile Telecommunications System (UMTS) network supports Cell Dedicated Channel (CELL_DCH), Cell Forward Access Channel (CELL_FACH), and Cell Paging Channel. (Cell Paging Channel is abbreviated as CELL_PCH), UTRAN Registration Area Paging Channel (URA_PCH for short) and Idle. After the UE completes the Packet Switch (PS) service, the current state transition policy of the wireless network operator is to directly migrate the state of the UE from the CELL_DCH state to the Idle state. The advantage of this state migration strategy is that it is simple to implement, but it also exposes its shortcomings from the current operational situation. First, the user's service experience is not very good. When the user initiates the PS service again, the UE needs to be migrated from the idle (Idle) state to the CELL_FACH state and then migrated to the CELL_DCH state. This process will generate more signaling interaction processes. For a long time, users must wait for a while to enjoy the wireless Internet, and the user experience will be poor. Secondly, as more and more users access the mobile Internet, the policy will lead to serious consumption of controller resources of the wireless network. Each time the state of the UE moves from the CELL_DCH state to the Idle state or the UE migrates from the Idle state to the CELL_FACH state. When migrating to the CELL_DCH state, the radio network controller and the Serving GPRS support node (SGSN) generate a lot of signaling interactions, consuming the processing resources of the radio network controller and the SGSN. The frequent migration of such a large number of users may result in the exhaustion of the resources of the wireless network controller and the SGSN, and even in the extreme case, the network is paralyzed, and the consequences are very serious. In order to circumvent the above two problems, there are two technical solutions to be solved. First, it is considered that the UE UE is not migrated to the Idle state after completing the PS service, but stays in the CELL_DCH state or migrates to the CEIX-FACH state. However, in the process of inventing, the inventor found that the strategy also has serious problems. First, the UE in the CELL_DCH state will cause interference of the cell, consume wireless resources, and cause unnecessary consumption of the cell resources, which affects the service experience of other users. Secondly, the UE in the CELL_DCH state consumes a very large amount of power, which is about 10 to 20 times that of the UE in the Idle state. This strategy will seriously affect the standby time of the UE. Second, the UE may be migrated from the CELL_DCH state to the CELL_PCH state or the URA_PCH state after the user completes the PS service. Under the premise of not considering the mobility problem, the UE power consumption of the CELL_PCH state and the URA_PCH state and the UE power consumption of the Idle state can be basically equal. Moreover, the UE needs to exchange less signaling from the CELL_PCH state or the URA_PCH state to the CELL_DCH state, the migration process time is shorter, and the user's service experience is better. However, the radio network controller needs to be in the CELL_PCH state or the URA_PCH state. The UE saves its user context information. Therefore, if a large number of UEs are configured in the CELL_PCH state or the URA PCH state, the capacity of the radio network controller will be greatly reduced.

The embodiments of the present invention provide a method and a system for migrating a UE state, which are used to solve the problem that only one state transition policy can be selected for all users in the prior art, and different user states cannot be implemented differently for different users. The technical problem of the migration strategy is to implement different user state migration strategies for different users. The above technical solutions will be described in detail below with reference to the drawings and embodiments of the specification. As shown in FIG. 1 , a first embodiment of the present application provides a method for migrating a UE state, which specifically includes: Step 101: Obtain service usage information of a UE in a specific time period; Step 102, analyze service usage information, from M Determining a user group as a home subscriber group of the UE in the user group; Step 103: Obtain a user state migration policy of the home subscriber group based on an index relationship between the M user groups and the defined N user state transition policies, The user state migration policy of the home subscriber group includes a first state before migration and a second state after migration; wherein, the M and the N are equal or unequal integers, and each of the M user groups The user group only corresponds to one of the N user state transition policies. Step 104: migrating the state of the UE from the first state according to a user state migration policy of the home user group. Second state. For the step 101, all the service usage information of the UE in a certain period of time is obtained, which is: collecting the service usage information of the UE in a certain period of time by using the IMEI, IMSI of the UE. The service usage information specifically includes: a time when the service is initiated, a time when the service ends, a service type used, and a total flow of the generated PS service. For example, the number of PS services performed in any consecutive 8 hours, the time interval of each PS service, and the like. Of course, a specific time period here can be selected according to the actual situation, and will not be stated here. The operator defines the M user groups that are softly and softly defined by the network device. The embodiment of the present application defines three user groups, which specifically include: a user group that rarely performs PS services; and a user group that frequently performs PS services; The default user group. In the actual application process, different user groups can be defined according to actual conditions, and will not be enumerated here. Similarly, the operator maintains the N user state migration policies defined by the system through the network device. The embodiment of the present application defines three user state policies corresponding to the user group according to the corresponding three user groups, which specifically includes: User state migration policy for PS services; User state migration policy for frequent PS services; Default user state migration policy. As above, in the actual application process, different user state migration policies can be defined according to actual conditions. The method as described above, in step 102, analyzing the service usage information, and determining a user group as the home user group of the UE from the M user groups, specifically: analyzing the service usage information of a certain UE, and determining The number of times that the UE user performs the PS service is less than the first threshold in a certain period of time, and each time the time interval of the PS service is greater than the second threshold, the "user group that rarely performs the PS service" is taken as The home subscriber group of the UE; for example, after analyzing the service usage information of the UE (A) for 8 consecutive hours, it is found that the number of times the UE (A) performs the PS service is 10 times, and the time of each PS service is performed. If the interval is greater than 30 minutes, the UE user is attributed to the "user group with little PS service" and stored in the database; or determined by analyzing the service usage information of a certain UE, at a specific time period. The number of times the UE performs the PS service is greater than or equal to the third threshold, and each time the time interval for performing the PS service is less than the second threshold, the "user group that frequently performs the PS service" is used as the home of the UE. a user group; wherein, the first threshold and the third threshold are equal or unequal integers; for example, after analyzing service usage information of the UE (B) for 8 consecutive hours, the UE(B) is found. The number of times the PS service is performed is 50 times, and the time interval of each PS service is less than 30 minutes. Then, the UE user is assigned to the "user group that frequently performs PS service", and is stored in the database, or is analyzed. The service usage information determines that the "default user group" is used as the home user group of the UE when the UE has not initiated the PS service. For example, if the UE (C) is a new user and has not recorded in the database before, the UE user is attributed to the "default user group". Of course, when the UE (C) performs the PS service next time, if the service usage information of the UE is found to satisfy the conditions of any user group of the "user group that rarely performs PS service" or "user group that frequently performs PS service" Then, the UE user is added to the user group that satisfies the condition. I won't go into details here. The index relationship between the M user groups and the defined N user state transition policies is based on the relationship between the three user groups and the index in the embodiment of the present application: The user status migration policy of the user group performing the PS service is indexed to the "user state migration policy for performing the PS service very rarely"; or The user state migration policy of the "user group that frequently performs PS service" is indexed to "user state migration policy of frequent PS service"; or the user state migration policy of the "default user group" is indexed to "default user state" Migration strategy". Through the foregoing index relationship, when a UE user belongs to a user group of the three user groups, the user status migration policy corresponding to the user group can be known by the index relationship, so that the user status corresponding to the UE user is known. Migration strategy. The specific content of the three user state transition policies defined in the embodiments of the present application is as follows: The user state migration policy for performing the PS service is rarely to migrate the state of the UE from the CELL-DCH state to the Idle state; for the user who rarely performs the PS service. , the state is migrated to the Idle state, so that even when the user performs the PS service again, since the time interval is long, the delay when returning from the Idle state to the CELL-DCH state is negligible and does not affect the user. Experience. The user state migration policy for frequent PS services is to migrate the UE state from the CELL-DCH state to the URA-PCH state. For users who frequently perform PS services, if they migrate to the Idle state, they return to the CELL- from the Idle state. In the DCH state, this process will generate more signaling interaction processes. The time is longer. The user must wait for a period of time to enjoy the wireless Internet. The user experience will be poor. Therefore, the state of the user who frequently performs the PS service is migrated to the URA. In the -PCH state, when the user performs the PS service again, the process of returning from the URA-PCH state to the CELL-DCH state is more efficient than the process of returning from the Idle state to the CELL-DCH state. Less, the migration process is shorter, and the user experience will be better. The default user state migration policy is to migrate the state of the UE from the CELL-DCH state to the Idle state. Because such users have not recorded before, so it is not known whether it is very rare to carry out PS services or PS services frequently, so the default is to migrate to the Idle state. After that, when it is found that the service usage information of a certain user of such a user satisfies the condition of one of the above-mentioned few and frequent users, the user is attributed to the user group that satisfies the condition. Therefore, in step 104, according to the user state migration policy of the home subscriber group, the state of the UE is migrated from the first state to the second state, specifically, when it is determined that the home subscriber group of the UE user is "pole" When the user group of the PS service is less, the state of the UE is migrated from the CELL-DCH state to the Idle state; or when it is determined that the user group to which the UE user belongs is the "user group that frequently performs the PS service", The state of the UE migrates from a CELL-DCH state to a URA-PCH state; or When it is determined that the UE user group of the UE is a "default user group", the state of the UE is migrated from the CELL-DCH state to the Idle state. As shown in FIG. 2, the second embodiment of the present application provides a system for migrating a UE state, which specifically includes: an obtaining unit 201, configured to obtain service usage information of a UE in a specific time period; and an analyzing unit 202, configured to analyze Determining, by the service usage information, a user group as a home subscriber group of the UE from the M user groups; the user state transition policy obtaining unit 203 is configured to set the N user states based on the M user groups and the defined N user states. The user relationship migration policy of the home subscriber group is obtained by the index relationship between the migration policies, and the user state migration policy of the home subscriber group includes a first state before migration and a second state after migration; And the N is equal or unequal integer, each user group of the M user groups only corresponds to one of the N user state transition policies; the migration unit 204 is set to follow The user state transition policy of the home subscriber group moves the state of the UE from the first state to the second state. The operator defines the M user groups that are softly and softly defined by the network device. The embodiment of the present application defines three user groups, which specifically include: a user group that rarely performs PS services; and a user group that frequently performs PS services; The default user group. In the actual application process, different user groups can be defined according to actual conditions, and will not be enumerated here. Similarly, the operator maintains the N user state migration policies defined by the system through the network device. The embodiment of the present application defines three user state policies corresponding to the user group according to the corresponding three user groups, which specifically includes: User state migration policy for PS services; User state migration policy for frequent PS services; Default user state migration policy. As above, in the actual application process, different user state migration policies can be defined according to actual conditions.

When the time interval is less than the second threshold, the user group that frequently performs the PS service is used as the home user group of the UE; wherein, the first threshold and the third threshold are equal or unequal integers; or The home subscriber group determining unit three 202C is configured to determine, by analyzing the service usage information,

When the UE has not initiated the PS service before, the default user group is used as the home subscriber group of the UE.
