Embodiment Construction

[0043] The present invention obtains the method flow chart of proxy call session control function IP address as shown in Figure 1, comprises the following steps:

[0044] Step s101, judging whether the terminal adopts the dynamic host configuration protocol to configure the terminal IP address, if yes, go to step s102; otherwise, go to step s103. Among them, the premise of obtaining the IP address of the P-CSCF is that the IP-CAN bearer is established. As a kind of IP-CAN, WiMAX should use the preset service flow to obtain the IP address of the P-CSCF after the preset service flow is established. address.

[0045]Step s102, while configuring the IP address of the terminal with the Dynamic Host Configuration Protocol, obtain the proxy call session control function IP address through the option of the Dynamic Host Configuration Protocol in conjunction with the Domain Name System Protocol.

[0046] Wherein, when configuring the IP address of the terminal with the dynamic host co...

Abstract

This invention provides a method for getting proxy call session control function IP address including: judging if a terminal applies a dynamic host collocation protocol to collocate its own IP address, if so, it gets the IP address by the selection of the dynamic host collocation protocol combining with domain name system protocol, otherwise, the terminal collocates its own IP address by the non-dynamic host collocation protocol then uses the selection combining with domain name system protocol to get the proxy call session control function IP address.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and system for acquiring an IP address of an agent call session control function. Background technique [0002] IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) is an open, standard, flexible and access-independent core network architecture first proposed by 3GPP (The 3rd Generation Partnership Project, 3rd Generation Partnership Project). Based on SIP (SessionInitiation Protocol, Session Initiation Protocol), IMS is applicable to both mobile and fixed IP services, and is widely recognized in the field as the core architecture of next-generation networks. Therefore, it is necessary to implement IMS access in various IP networks. For example, networks such as WiMAX (Worldwide Interoperability Microwave Access, Worldwide Interoperability for Microwave Access). [0003] WiMAX is a wireless metropolitan area network technology based on 802.16d / e. The IEEE802.16 st...
