Problems solved by technology

However, currently some UEs do not support the load migration function
For a UE that does not support the load migration function, if the method described in the above protocol is used, it cannot recognize that the monitored LAI is different from the newly allocated Non Broadcast LAI, and cannot re-initiate the location update process, which will cause the load of the pool area Migration does not work properly
It can be seen that in the prior art, for some UEs that do not support the load migration function, normal pool area load migration cannot be completed

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] The embodiment of the present invention proposes a method for pool area load migration, see figure 1 , figure 1 It is a flowchart of a method for implementing pool area load migration in an embodiment of the present invention. This embodiment takes the NNSF node as an example, and the initial message is an initial non-access stratum (initial NAS) message as an example, but it is not limited thereto, and the following embodiments will not repeat them. The method includes:

[0021] Step 101: After receiving the initial NAS message sent by the UE, the NNSF node selects the destination CN node of the initial NAS message from CN nodes that do not perform load migration;

[0022] Step 102: Route the initial NAS message to the selected ...

Abstract

The invention relates to a method for realizing the load transfer of a pool area. The method of the invention comprises the steps that: after an initial message sent by subscriber equipment (UE) is received, a target CN node of the initial message is selected from CN nodes which carry out no load transfer and the initial message is routed to the selected target CN node. The invention also provides a system for realizing the load transfer of the pool area and the system can realize the load transfer of the pool area without the support from UE.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method and system for realizing pool area load migration. Background technique [0002] In the field of mobile communication, since the fifth version of the third generation partnership (3GPP R5, Third Generation Partnership Projects R5), the multi-Iu interface (Iu-Flex) technology has been introduced, which supports a radio access network (RAN, Radio Access Network) node to the intra-domain connection routing function between multiple core network (CN, Core Network) nodes, wherein the radio access network (RAN, Radio Access Network) node can be a radio network controller (RNC, Radio Network Controller ) or a base station controller (BSC, base station controller), the CN node may be a mobile switching center (MSC, Mobile Switching Centre) or a serving general packet radio service support node (SGSN, Serving GPRS Supporting Node). The RAN node has a non-access stratum ...
