Abstract
The invention relates to a method and device to quit network in wireless communication network. The invention includes: when the identification authorized charging sever decides that it accords with condition of quit network, then build the require messages for quit network, and sends it to network unit which can execute the operation of quit network; and the network unit receives require messages for quit network from identification authorized charging sever, and executes the operation of quit network according to the messages. It can be seen that, in invention the identification authorized charging sever replaces the mobile terminal to inform the local agent to delete the registration of mobile IP, and the identification authorized charging sever can initiate the quit network, so, the invention can realize the operation of quit network in various applied scenes to improve the efficiency of quit network.
Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of scheme of quit network in wireless communication network.
Background technology
Along with the fast development of the communication technology, IP-based mobile communications network, promptly the application of mobile IP network is increasingly extensive.
In mobile IP network, the processing procedure that relates to registration and go to register.Wherein, move in the process of going to register of IP in existing standard, the registration of going of mobile IP is normally initiated by mobile node.
The concrete location registration process process of going comprises: at first send and go register requirement to foreign agent entity, and go accordingly after the location registration process by Foreign Agent, send to home proxy entity again and go register requirement, go the registration operation with the notice home agent, thereby finish the whole location registration process process of going.
In the time of in being applied to wireless network, the process business of the signaling of mobile IP between portable terminal and base station is connected transmission, if professional the connection when existing then can successfully adopt the above-mentioned registration process of going to go location registration process accordingly.
Yet the business that is used to transmit mobile IP signaling connects and can not guarantee to be bound to exist.If being used to transmit the business of mobile IP signaling connects and does not exist, then, present home agent goes register requirement because only trusting by what mobile node sent, and can not trust the register requirement of going that Foreign Agent sends, therefore, in order to be implemented in the location registration process of going of the mobile IP that moves back when net, also need to rebuild the professional connection of air interface, afterwards, utilize the business that rebulids to connect the location registration process of going of carrying out mobile IP again.
Be not difficult to find out that present mobile IP removes to register implementation under some applicable cases, will at first bigger negative effect to the net efficient of moving back of wireless network, make that moving back net efficient reduces greatly.
Summary of the invention
The purpose of this invention is to provide a kind of method and device of quit network in wireless communication network, thereby make and to realize the net operation that moves back under the various application scenarioss in the wireless network neatly, effectively improve the efficient of moving back net operation.
The objective of the invention is to be achieved through the following technical solutions:
The invention provides a kind of method of quit network in wireless communication network, comprising:
