Method for providing service to circuit field user via group field

Abstract

A method of utilizing packet domain to provide service of circuit domain user includes expanding network node function of MGCF, S-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...

Problems solved by technology

[0018] In practical applications, the above solutions have the following problems: the solution to directly provide services to fixed network users through network nodes in the circuit domain is expensive, slow to deploy, and the user interface is single, which is not conducive to promotion; The solution for network users to provide services requires repeated business development, and cannot directly allow fixed network users to access IMS services, resulting in high operating costs

[0019] The main reason for this situation is that the existing fixed network circuit switching mode is not flexible enough, and the cost of network facilities is high; and the IMS network does not provide a session protocol for direct access to fixed network users, and fixed network users cannot directly use the services provided by IMS
