Registrating roaming custom IP address in evolution network and service using method

Abstract

The present invention is appropriate for the wireless communication field, and provides a roaming user IP address register and service use method in an evolution network. Said method includes the following steps: A, a UE originating register to a visited network; B, the visited network feeding back Local Breakout route optimizing strategy information of the UE to the UE; and C, in proceeding service originating IMS register, the UE, according to said Local Breakout route optimizing strategy information, judging whether the service uses the route optimization function to register the allocated IP addresses of home network or visit network to the IMS system. In the invention, the UE acquires the Local Breakout route optimizing strategy information when the UE is registered to the visited network, registers or uses the IP address allocated by the home network and the IP address allocated by the visit network according to whether the route optimization function can be used by the service when initiating service register or performing service register, which solves the register and use problem of the two IP addresses.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a method for registering an IP address of a roaming user in an evolutionary network, a method for using a service, and a method for obtaining route optimization policy information. Background technique [0002] The network structure of the existing General Package Radio Service (General Package Radio Service, GPRS) / Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, UMTS) is as follows: figure 1 As shown, a structure similar to that of the second generation mobile communication system is adopted, including UMTS Territorial Radio Access Network (UTRAN), GSM / EDGE Radio Access Network (GSM / EDGE Radio Access Network, GERAN) , a core network (Core Network, CN) and a user terminal (User Equipment, UE). Among them, GERAN / UTRAN is used to implement all wireless-related functions, while CN handles all voice calls and data connections i...

Problems solved by technology

[0010] The purpose of the present invention is to provide a method for registering and using the IP address of a roaming user in an evolved network, aiming to solve the problem of how the UE registers with the IMS the two IP addresses assigned by the home network and the visited network in the evolved network

[0011] Another object of the present invention is to provide a method for using IP addresses of roaming users in an evolved network, aiming to solve the problem of how to use the two IP addresses assigned by the home network and the visited network when the UE performs services in the evolved network
