Embodiment Construction

[0098] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0099] According to the framework of the interconnection between the circuit domain of the fixed network and the IMS and the IMS session processing specification, the invention provides the session flow and the related processing method for the fixed network user to access the IMS. First of all, fixed network users can be identified by a SIP Universal Resource Locator (Universal Resource Locator, "URL" for short) in the IMS domain or by a Public Service Identity (Public Service Identity, "PSI" for short) through their IMS service subscription information, then The subscription information of the corresponding user or PSI is maintained and managed by the HSS for query and download by other functional entities. Secondly, whether the fixed network user subscribes to ...

Abstract

A method of utilizing packet domain to provide service of circuit domain user includes expanding network node function of MGCF, S ¿C CSCF and AS to make IMS not only support interworking call of firm network circuit domain but also provide service for firm network domain user, furthermore expanding HSS function to store and manage IMS contracted service data related to firm network circuit domain user.

Description

technical field [0001] The invention relates to a method for integrating a packet domain network and a circuit domain network, in particular to a method for providing services to circuit domain users through the packet domain. Background technique [0002] The rapid development of optical communication technology and broadband Internet Protocol (Internet Protocol, referred to as "IP") technology has enabled the communication backbone network to have a strong application support capability, and bandwidth is no longer the main difficulty for operators to develop services. However, from the perspective of the development of the global telecom market, the voice and data service markets are becoming increasingly saturated, causing operators to face the dilemma of decreasing business growth year by year and increasingly difficult customer development. Therefore, both emerging operators and traditional operators are looking for new market opportunities and business models, so as to...
