Embodiment 1

[0022] Embodiment 1: Realize the system in which the circuit program-controlled exchange dispatching station and the softswitch dispatching station are mixed in the same group

[0023] A system for realizing the mixing and grouping of circuit program-controlled switch dispatching consoles and softswitch dispatching consoles, including a program-controlled switch based on the PRI protocol and a soft switch based on an internal private protocol, characterized in that the system also includes a PRI protocol-based and extended A gateway for SIP protocol conversion; the soft switch is provided with a module for bidirectional conversion between an internal private protocol and an expanded SIP protocol; the program-controlled switch and the gateway are bidirectionally connected through an E1 channel; the gateway and the soft switch are bidirectionally connected through an IP network.

Embodiment 2

[0024] Embodiment 2: Realize the method of mixing the circuit program-controlled switching dispatching station and the softswitch dispatching station in the same group

[0025] A method for realizing circuit program-controlled exchange dispatcher and softswitch dispatcher mixed in the same group is characterized in that it comprises the following steps:

[0026] A. On the program-controlled exchange, increase dispatcher group number and dispatcher group members A and B, wherein A is a local dispatcher, and B is a remote dispatcher;

[0027] B. When the user under the program-controlled exchange calls the group number of the dispatcher, the program-controlled exchange performs call analysis; when the purpose of the user's call is the local dispatcher A, the program-controlled exchange sends the PRI protocol to the local dispatcher SETUP message; when the user call purpose is the remote dispatcher B, the program-controlled exchange sends the USR TO USR message of the ringing m...

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 ...
