[0071] Figure 4 Shown is the first embodiment of the present invention, which is a method for a new GGSN to obtain terminal context information, which mainly includes the following steps:

[0072] Step 401: The new GGSN sends a context request (ContextRequest) message to the original GGSN, requesting the original GGSN for context information about a certain terminal, including the PDP context (PDPContext) information of the terminal.

[0073] The context request message at least carries the identifier of the terminal. Preferably, the terminal identifier is an IMSI (International Mobile Subscriber Identification, International Mobile Subscriber Identification) or an identity identifier (AID) of the terminal, and the AID can uniquely mark the terminal as the identifier of the terminal in the network. Preferably, if context information of multiple terminals needs to be requested, the message may carry identifiers of multiple terminals.

[0074] Preferably, the message can also...

Embodiment 2

[0084] Figure 5 Shown is the second embodiment of the present invention, which is another method for the GGSN to acquire terminal context information. In this embodiment, when the new SGSN selects a new GGSN, a trigger message is sent to the new GGSN, and the new GGSN terminal is notified of the identity of the GGSN (original GGSN) to which the terminal is currently attached, and the new GGSN is triggered to request the original GGSN for the context information of the terminal, specifically Contains the following steps:

[0085] Step 501: During the process of performing location management (such as redirection and routing area update) for the terminal, when the new SGSN selects a new GGSN for the terminal (for example, according to the local configuration policy of the new SGSN), the new SGSN sends the new GGSN to the new SGSN. The GGSN sends a trigger message, which at least needs to carry the identifier of the terminal and the identifier of the GGSN (ie, the original GGSN...

Embodiment 3

[0108] In order to solve the problems existing in the prior art, that is, there are roundabout routes due to the existence of fixed anchor points, resulting in a series of adverse consequences, the present invention provides a method for location management, which solves the problem of prior art by eliminating fixed anchor points. Existing problems. exist figure 1 On the basis of the network architecture shown, the present invention adds a new logical network element called "mapping server", or "Identity Location Register (ILR)". The network element may exist in the form of an independent physical entity, or may exist in the form of logical functions in other physical entities (for example, in an AAA server, HLR, etc.). Corresponding to the above two forms, it is necessary to establish a new interface between the GGSN and the network element, or to reuse and expand the existing interface.

[0109] The present invention also needs to assign an identity mark and a location mar...

Abstract

The present invention relates to a method for acquiring terminal context, a method for position management, a system, and a network element. The method for acquiring terminal context includes: a new gateway GPRS support node (GGSN) sends a message to the original GGSN to request context information of a mobile terminal , which carries the identifier of the terminal; the old GGSN provides context information of the terminal to the new GGSN, and the context information includes the PDP context of the terminal. The invention solves the problem that the new GGSN cannot serve normally, and at the same time solves the problem of the circuitous path through the triggering of the new SGSN.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for acquiring terminal context, a method for location management, a system and network elements (including SGSN and GGSN). Background technique [0002] Existing Wideband Code Division Multiple Access (WCDMA) system\Time Division Code Division Multiple Access (TimeDivision-Code Division Multiple Access, TDCDMA) is an important system and method for realizing service access based on wireless WCDMA / TDCDMA technology at present, and its network architecture is as follows: figure 1 shown. Including radio access network, and network elements such as serving GRPS (General Packet Radio Service, General Radio Packet Service) support node (ServingGPRSSupportNode, SGSN), gateway GPRS support node (GatewayGPRSSupportNode, GGSN) and terminals. Wherein, the radio access network mainly includes a base station and a radio network controller (Radio Network Controller, RNC). ...
