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

[0046] See figure 1 As shown, the load migration process in this embodiment mainly includes the following steps:

[0047] Step 101: The UE initiates a location update request to the source MSC through the BSC / RNC.

[0048] Step 102: After receiving the location update request initiated by the UE, the source MSC first determines whether the UE meets the relocation conditions, such as judging whether the UE belongs to the user to be relocated and whether the UE is located in an Iu / A-Flex-enabled RAN according to the IMSI number segment of the UE. If it is, it will query the "NRI Number" table according to the destination NRI indicated by the O&M to determine the destination MSC, and send a redirect request (Redir Req) message to the destination MSC.

[0049] If the table lookup is unsuccessful, the source MSC directly completes the location update in the local office, and does not migrate the user.

[0050] Among them, the redirection request message generally carries user information ...

Embodiment 2

[0069] See figure 2 As shown, the load migration process in this embodiment mainly includes the following steps:

[0070] Step 201: The UE initiates a service request or paging response to the source MSC.

[0071] 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 RR connection is released at the end of the call and The destination MSC sends a redirection request message.

[0072] If the table lookup is unsuccessful, the source MSC sends CLR_CMD to the BSC / RNC where the UE is located to release the RR connection, does not relocate the user, and ends the current process.

[0073] Among them, the user information carried in the redirection request message includes: IMSI and new LAI. Optionally, authentication and encryption information can also be carried in the message. In the case of non-location update,...

Embodiment 3

[0082] See image 3 As shown, the load migration process in this embodiment mainly includes the following steps:

[0083] Step 301: The UE initiates a routing domain update request to the source SGSN.

[0084] 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.

[0085] If the table lookup is unsuccessful, the source SGSN will directly complete the routing domain update in the local office and end the processing of this flow.

[0086] Different from Embodiment 1 and Embodiment 2, at this time, the redirection request message carries IMSI, packet domain temporary mobile user identity (P-TMSI), new routing domain identity (RAI), old RAI, authentication encryption User information such as information and user status.

[0087] Step 303: After receiving the red...

Abstract

A method for implementing load migration in a pool area is disclosed. The method includes that: the destination CN node receives an identifier of a subscriber ready for migration; and the destination CN node migrates the subscriber ready for migration to the destination CN node, and allocates a local office identifier to the migrated subscriber. In addition, a system for implementing load migration in a pool area and a CN node are disclosed.

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 difficult. Complicated, it is easy to increase 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-Division Synchronization Code Division-Multiple-Access), Glo...
