Abstract

The invention discloses a system and method for mixing a program-controlled switch dispatching desk and a soft switch dispatching desk and relates to the next generation of network technology. The system for mixing dispatching desks comprises a program-controlled exchange, a soft switch and a gateway, wherein the program-controlled exchange and the gateway are connected through an E1 channel and communicate with each other through a private protocol based on PRI (primary rate interface) protocol; the gateway and the soft switch are connected through an IP (Internet protocol) network and communicate with each other through an expanded SIP (session initiation protocol); and the gateway performs conversion between the private protocol based on PRI protocol and the expanded SIP. The system and the method provided by the invention have the beneficial effect that seamless fusion between the soft switch and the circuit program-controlled switch is finished with a very low cost, and the functions of a dispatching system can be enriched and the steady operation of the original dispatching system can be ensured. Moreover, no modification is performed on the program-controlled exchange, the waste of the dispatching resources is avoided, the deployment cost of the dispatching system is lowered, and smooth transition from a program-controlled dispatching system to a soft switch dispatching system is realized.

Description

technical field

[0001] The invention relates to the next-generation network technology, in particular to a system and method for realizing mixed grouping of a circuit program-controlled dispatching station and a soft-switching dispatching station. Background technique

[0002] In communication applications in various industries, digital program-controlled switches based on circuit program-controlled switching technology have been deployed on a large scale, especially in the field of dispatch communication, where functions such as forced insertion, forced removal, group call, and roll call of dispatching consoles have been widely used. However, with the continuous development of communication technology, especially IP technology, some new functional requirements, such as video conferencing and instant messaging, cannot be realized in traditional circuit program-controlled switching technology.

[0003] Next Generation Network (NGN) technology has gradually replaced circuit ...
