Problems solved by technology

This kind of processing fails to achieve the purpose of load redistribution to MSC, and cannot guarantee the dynamic balance of MSC load.
[0043] According to the current agreement, the SGSN cannot obtain the current load status information of the MSC, so the SGSN cannot select the MSC according to the load, nor can it redistribute the load
Even if the SGSN can obtain the load information of the MSC, the selection of the MSC by the SGSN also violates the idea that the RAN node is an LCDN, resulting in multiple LCDNs, that is, two LCDNs including the RNC and the SGSN at this time, making the decision points inconsistent. And the decision-making mechanism will become very complicated

Embodiment Construction

[0067] The core idea of ​​the present invention is: when the mobile terminal initiates a joint RA / LA update process to the wireless access network node, and there is a Gs interface, the present invention performs the simultaneous update on the SGSN and the MSC at the wireless access network node specified in the protocol. Load redistribution selects the MSC with the best current load status, which ensures the dynamic balance of MSC load and the unity of load control decision nodes.

[0068] 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 with reference to the accompanying drawings and preferred embodiments.

[0069] figure 2 It is a flow chart of joint RA / LA update processing in the case where the Gs interface exists in the present invention, and specifically includes the following steps:

[0070] Steps 200 to 201: the RAN node receives the routing area update req...

Abstract

The invention relates to a method for realizing load redistribution when coupling route / refreshing position, when there is Gs interface exists. Wherein, at the wireless access network node, the invention processes load redistribution on service GPRS support node (SGSN) and MSC at the same time; selects right SGSN and MSC as target SGSN and target MSC; and transmits selected target MSC mark to target SGSN; and the target SGSN, only according to target MSC mark, sends the position refreshing request to target MSC, to confirm the dynamic balance of MSC load, and make the load control decision node (LCDN) uniform.

Description

technical field [0001] The invention relates to load redistribution technology, in particular to a method for realizing core network (CN) node load redistribution in joint routing / location (RA / LA) update under the condition of Gs interface. Background technique [0002] The 3rd Generation Partnership Project (3GPP) standard TS23.236 proposes the concept of pool area, that is, the area covered by several radio access network (RAN) nodes, such as radio network controller (RNC) or base station controller (BSC) Form a pool area. A pool area is usually served by several CN nodes in parallel, and can also be served by one CN node. When a pool area is served by several CN nodes in parallel, these CN nodes form a CN node pool, that is, an MSC pool or a Serving GPRS Support Node (SGSN) pool. [0003] In order to identify a CN node in a CN node pool, each CN node is assigned one or several Network Resource Identifiers (NRIs), and the assigned NRIs are configured in the CN node throu...
