Embodiment Construction

[0035] The HA is the home agent in the mobile IP technology, and acts as a gateway device in the WiMAX system to connect to the Internet or other systems (such as IMS), and is the egress of the WiMAX network. The invention provides a method for acquiring P-CSCF address from HA. The main idea of ​​the present invention is to configure the IP address of the P-CSCF on the HA, or the IP address of the P-CSCF domain name and the DNS server, and register the address of the P-CSCF or the P-CSCF domain name and the DNS server through the mobile IP registration response message. The address of the ASN-GW is notified to the functional entity DHCP agent of the ASN-GW, and the DHCP agent stores relevant information. After the mobile IP registration is completed, the terminal initiates a DHCP query to obtain the address of the P-CSCF or the domain name of the P-CSCF and the address of the DNS from the DHCP agent. If the domain name of the P-CSCF is obtained, the terminal needs to query th...

Abstract

The method includes steps: (1) when terminal initiates logging on Internet protocol, i.e. mobile IP registration, home agent HA informs address information of proxy call session control function P-CSCF to access gateway ASN-GW; ASN-GW saves the address information of P-CSCF; (2) the terminal obtains the address information of P-CSCF from ASN-GW. The invention makes user obtain address of P-CSCF from HA so as to let user access IMS network and use IMS service.

Description

technical field [0001] The present invention relates to obtaining an access point of an IP multimedia network to act as a proxy call session control when a user accesses an Internet Protocol (IP) multimedia network (IP Multimedia Subsystem, IMS) through a World Interoperability for Microwave Access (WiMAX, World Interoperability for Microwave Access) network Method of function (P-CSCF) address. Background technique [0002] WiMAX is a broadband wireless access technology based on the IEEE 802.16 standard, which can effectively use limited wireless spectrum resources to provide a larger air interface bandwidth (up to 70Mbps data transmission capability). Its network reference model is shown in Figure 1. It consists of three logical entities: registered terminal / mobile terminal (SS / MS), access service network (ASN) and connection service network (CSN). Each logical entity represents a group of Functional entity, each function can be implemented in a single physical device or ...
