specific Embodiment approach

[0053] FIG. 5 is a diagram of the correspondence relationship between RA and TA according to the embodiment of the present invention. Referring to FIG. 5 , the routing area RA1 of the UMTS intersects with the tracking areas TA1 and TA2 in the SAE; the tracking area TA1 in the SAE intersects with the routing areas RA1 and RA2 in the UMTS. The control plane functional entity MME needs to save the TA list intersecting with RA1: TA1 and TA2, and save the RA list intersecting with TA1: RA1 and RA2.

[0054] After the user powers on and registers in the RA1 of the UMTS, the registration in the SAE is triggered by a PDP (Packet Data Protocol, packet data protocol) context activation message. The MME of the SAE selects TA1 from the TA list intersecting with RA1, takes TA1 as the tracking area where the user is currently located, allocates the SAE temporary mobile subscriber identity S-TMSI, and returns the TA1 to the terminal through UMTS. The MME saves the RA1 and the TA1.

Abstract

The invention is used for initiating call to the client terminal in an area covered by both global mobile communication system and the system architecture evolution (SAE) network; after the control plane entity in said communication system receives a paging request for paging said client terminal, it decides if the client terminal is at the coverage range of the SAE access system; if yes, then only initiating a paging in said SAE access system; otherwise, initiating the paging request in both global mobile communication system access system and SAE access system. Said mobile communication system at least comprises a control plane function entity used for deciding if the client terminal is at the coverage range of the SAE access system after receiving the paging request from said client terminal.

Description

technical field [0001] The invention relates to a mobile communication paging technology, in particular to a method for performing paging when the third generation mobile communication system packet domain and the next generation packet domain cover each other in the mobile communication system. Background technique [0002] Since the invention of the cellular communication system, wireless transmission technology has made great progress, from the first generation of analog wireless technology to the second generation of digital wireless technology, and invented the digital mobile communication system GSM (Global system for Mobile communications) , The GSM system mainly provides voice services, and the highest data rate is 9.6kb / s. [0003] GPRS (General Packet Radio Service) is a GSM-based mobile packet data service that provides users with IP or X.25 connections for mobile packets. The GPRS system is based on packet switching technology, and users can use various high-spe...
