Description

A Method for Realizing Short Message Function of SIP Terminal

technical field

The invention relates to the field of softswitch value-added services, in particular to a method for realizing the short message function of a SIP (Session Initiation Protocol) terminal on an NGN (Next generation network) network.

Background technique

Softswitch is a technical system that provides carrier-class services to users by separating service from call control, and call control from bearer. An open service system for users and multimedia. At present, the service development capability of softswitch has expanded from simple telephone service and intelligent network service to an application-driven softswitch system with multimedia service capability and customized according to requirements.

The realization of the softswitch value-added service usually depends on the application server to complete. The application server is responsible for the logic generation and management of various value-added services, and also provides various open APIs (Application Programming Interface), providing a creative platform for the development of third-party services. The application server is an independent entity and has nothing to do with the softswitch of the control layer, thus realizing the separation of service and call control, which is conducive to the introduction of new services. At present, although the service capability provided by the application server is very powerful, it not only supports the traditional calling telecommunication services, but also provides value-added services such as SMS, MMS and positioning. Therefore, the application server has become one of the core devices in the NGN (Next generation network) network.

However, for SIP terminals (including soft terminals and hard terminals) registered on softswitches, their basic telecommunication service capabilities are mainly focused on call-type telecommunication services. At present, no relevant SIP terminal short message function has been retrieved. Technical solutions.
