Problems solved by technology

In the ISPAGE2 scheme, when the inter-system paging is successful, it indicates that the true location of the mobile station is within the coverage of the edge MSC, but the mobile station has not initiated registration at the edge MSC, and there is no profile information, so it is impossible to perform mobility restriction checks at the edge MSC; According to the message structure of intersystem paging defined by the existing ANSI41D protocol, the location information of the edge MSC cannot be transmitted to the serving MSC, so the mobility restriction check cannot be performed on the serving MSC.

Embodiment 1

[0024] Embodiment 1. This embodiment occurs in a CDMA mobile communication system, and the intersystem paging adopts the ISPAGE2 scheme. In this embodiment, the serving MSC has an edge MSC, and there is an adjacent location area in the registered location area for illustration. figure 1 The corresponding relationship between the serving MSC, the edge MSC and adjacent location areas in this embodiment is shown. In practical applications, there may be but not limited to one edge MSC and adjacent location area.

[0025] In the serving MSC, configure the corresponding relationship between the serving MSC and the edge MSC, the registration location area and the adjacent location area. In practical applications, one location area under the serving MSC may be configured with multiple adjacent location areas of the same or different edge MSCs.

[0026] At the same time, configure the mapping relationship between adjacent location areas and virtual cells under the serving MSC, and ma...

Abstract

Characters are that the method includes following steps: mapping location area of each peripheral MSC into a virtual sector; (2) collocating service area corresponding to the virtual sector in the configuration table; (3) after successful seeking between systems, based on the location area from the returned seeking response, service MSC has queried corresponding virtual sector, and further looks up the configuration table to obtain the service area the mobile station locates on currently; using service list of the service area, the service MSC carries out controlling current services of the mobile station. When there is no information of sector of the mobile station after seeking between systems, the invention uses current flow to implement function of restricting mobility under conditionwithout changing network architecture of current CDMA communication system and current protocol. Thus, the scheme in the invention is simple and feasible.

Description

technical field [0001] The invention relates to a switching subsystem in a CDMA (Code Division Multiple Access) mobile communication system, in particular to a method for realizing the mobility restriction function after inter-system paging. Background technique [0002] The CDMA mobile communication system includes network entities such as MSC / VLR (Mobile Switching Center / Visitor Location Register), HLR (Home Location Register), BSC (Base Station Controller), and mobile stations. [0003] Inter-system paging means that when the serving MSC (the MSC registered by the mobile station) issues paging to the location area under this MSC, it simultaneously sends an inter-system paging request to the edge MSC (an MSC adjacent to the serving MSC), requiring the edge MSC to The mobile station is also paged simultaneously in the corresponding adjacent location areas. After the mobile station is successfully paged at the edge MSC, the call is established to the edge MSC. The 3GPP2ANS...
