A key customer system based on IP multimedia core network

Abstract

The invention relates to a major client system based on IP multimedia core network. The major client system is divided into a server and a client end. The server is used to realize application and business functions. The client end is used for providing user interface; the server and client end conduct communication through SIP (Session Initiation Protocol), TCP (Transmission Control Protocol) orUDP (User Data Protocol). The server and the client end are built by functional modules which can be extended conveniently. Compared with prior art, the invention is based on IMS core network, the major client system interacts with the application server in the network using SIP protocol; the system itself adopts server and client mode, capable of configuring various functions of relevant applications to meet different user needs. Compared with the framework of major client system in conventional exchangers, the invention is more flexible and more conducive to business operation.

Description

technical field [0001] The invention relates to a VIP client system, specifically a VIP client system implemented on an IMS (IP Multimedia CoreNetwork Subsystem, IP Multimedia Subsystem) network. Background technique [0002] The key customer system is a communication system that serves enterprises and institutions such as hotels, companies, and government agencies. It is the main source of income for telecom operators and is of unparalleled importance to telecom operators. The large customer system of the demand is very important. [0003] The key customer system of the traditional switch network has no clear system architecture, poor service expansion capability, and cannot well meet the new needs constantly raised by key customers, so it cannot be transplanted to the IMS network for use at all. All the functions provided by the traditional switch network for large customers are realized in the switch software. The division of labor between the front and back is not clear...

Problems solved by technology

[0003] The large customer system of the traditional switch network has no clear system architecture, poor business expansion capability, cannot meet the new needs of large customers, and cannot be transplanted to the IMS network at all.

All the functions provided by the traditional switch network for large customers are implemented in the switch software. The division of labor between the front and back is not clear, and there is no obvious hierarchy. Moreover, these functions can only be provided at the same time, and there is no corresponding configuration to control the use of functions. Inability to flexibly choose the desired function
