Problems solved by technology

However, some UEs currently on the market cannot actively initiate location updates after receiving Non-Broadcast LAI
For this type of UE, if the load migration is performed according to the existing method, it is easy to cause some user services to fail, resulting in a decline in service quality and affecting user experience

Embodiment 1

[0036] see figure 1 As shown, the load migration process in this embodiment mainly includes the following steps:

[0037] Step 101: the UE initiates a location update request to the source MSC through the BSC / RNC.

[0038] Step 102: After the source MSC receives the location update request initiated by the UE, it first judges whether the UE meets the relocation conditions, such as judging whether the UE belongs to the user to be relocated according to the IMSI number segment of the UE and whether the UE is located in the RAN where Iu / A-Flex is enabled, If yes, query the "NRI Number" table according to the destination NRI indicated by the O&M to determine the destination MSC, and send a redirection request (Redir Req) message to the destination MSC.

[0039] If the table lookup is unsuccessful, the source MSC will directly update the location in the local office without migrating the user.

[0040] Wherein, the redirection request message generally carries user information su...

Embodiment 2

[0059] see figure 2 As shown, the load migration process in this embodiment mainly includes the following steps:

[0060] Step 201: UE initiates a service request or paging response to the source MSC.

[0061] Step 202: If the UE meets the relocation conditions and is located in the Iu / A-Flex-enabled RAN, the source MSC will query the "NRI Number" table according to the NRI indicated by the O&M to determine the destination MSC before the call ends and the RR connection is released. The destination MSC sends a redirection request message.

[0062] If the table lookup is unsuccessful, the source MSC sends a CLR_CMD to the BSC / RNC where the UE is located to release the RR connection, does not migrate the user, and ends the current processing.

[0063] Wherein, the user information carried in the redirection request message includes: IMSI and new LAI. Optionally, authentication encryption information may also be carried in the message. In the case of non-location update, the ...

Embodiment 3

[0072] see image 3 As shown, the load migration process in this embodiment mainly includes the following steps:

[0073] Step 301: UE initiates a routing domain update request to the source SGSN.

[0074] Step 302: If the UE meets the relocation conditions and is located in the Iu / A-Flex-enabled RAN, the source SGSN queries the "NRI Number" table according to the NRI indicated by the O&M to determine the destination SGSN, and sends a redirection request message to the destination SGSN.

[0075] If the table lookup is unsuccessful, the source SGSN directly completes the routing domain update at the local office, and ends the processing of this flow.

[0076] The difference from Embodiment 1 and Embodiment 2 is that at this time, the redirection request message carries IMSI, packet domain temporary mobile subscriber identity (P-TMSI), new routing domain identity (RAI), old RAI, authentication encryption information, user status and other user information.

[0077] Step 303: Af...

Abstract

The invention relates to a method for implementing the load migration in a pool area, comprising the following steps that: a target core network CN node receives migrated user identification; and the target CN node enables a migrated user to migrate to the target CN node and allocates local identification to the migrated user. At the same time, the invention also provides a system for implementing the load migration in the pool area and a CN node.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method, a system and a core network (CN, Core Network) node for realizing load migration in a pool area (Pool Area). Background technique [0002] In the traditional mobile communication network architecture, a base station controller (BSC, Base Station Controller) or a radio network controller (RNC, Radio Network Controller) can only connect to one CN node. This networking method is not flexible enough, and network planning is more complicated , It is easy to cause an increase in the investment cost of network equipment. In order to solve this problem, since the fifth version of the third generation partnership (3GPP R5, Third Generation Partnership Projects R5), Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access), Time Division Synchronous Code Division Multiple Access (TD-SCDMA , Time-DivisionSynchronization Code Division-Multiple-Access)...
