Updating method of routing area/location area

Abstract

This invention discloses one router area and position update method, which comprises the following steps: a, mobile bench sends router label RAI with original route to set area business supportive point to update require information by label RAI, new RAI and update parts; b, SGSN requires new visit position register VLR for position updating after receiving router area requires message to expresscross router area and position update.

Description

technical field [0001] The invention relates to mobility management technology in a mobile communication system, in particular to a routing area (RA) / location area (LA) updating method. Background technique [0002] In Global System for Mobile Communications (GSM) / General Packet Radio Service (GPRS) and Universal Mobile Network (UMTS) systems, a mobile station (MS) as a terminal can enjoy the circuit domain (CS) and packet domain (PS) provided by the network. business. There are multiple location areas in the CS domain, and each location area is represented by a unique location area identifier (LAI), so that the visitor location register (VLR) can determine the location of the MS; there are multiple routing areas in the PS, and each routing area The area is also represented by a unique routing area identifier (RAI), so that the packet domain service support node (SGSN) can determine the location of the MS. A location area may include multiple routing areas, and a routing a...

Problems solved by technology

However, in situations such as the MS moving back and forth rapidly between the two communication systems, the RAI may not be updated in time

In this way, when the MS moves back to the area corresponding to the original RAI, the joint routing area / location area update is performed, so that the SGSN will not initiate a location update to the VLR because the SGSN misjudges that the LAI has not changed, thereby causing the circuit domain service to fail.
