System and method for realizing intercommunication of IP telephone and interphone system through multicast

Abstract

The invention discloses a system and method for realizing intercommunication of an IP telephone and an interphone system through multicast. The system for realizing the intercommunication of an IP telephone and an interphone system through the multicast comprises a intercom application server, a intercom connection server and an interphone. The intercom application server comprises a configurationmanagement module, a soft switch communication module, a media stream multicast module and a control protocol module. The intercom connection server comprises a media stream multicast transmit-receive module and a control module. The method for realizing the intercommunication of the IP telephone and the interphone system through the multicast comprises the following steps that step1, a user dials in an off-hook mode; step2, a telephone terminal is connected to soft switch; step3, the soft switch is communicated with the intercom application server; and step4, applying the intercom application server, a waiting telephone user button and the like. In the invention, long distance intercom and seamless communication can be realized.

Description

technical field [0001] The present invention relates to a system and method for realizing intercommunication between IP phone and walkie-talkie system through multicast, in particular to a system and method for realizing intercommunication between IP phone and walkie-talkie system through multicast. Background technique [0002] The walkie-talkie system is widely used in all walks of life and various places: airports, bars, construction sites, KTV, dispatching and other noisy places. It should be said that walkie-talkies in these places are more practical and more effective. [0003] But the defect of the walkie-talkie is also obvious: the call distance is short, and everyone must be within the radiation range of the walkie-talkie to communicate. Now simulate a scenario. For example, a company has two branches in Beijing and Shanghai. When the Beijing company has an emergency and needs to be notified immediately to the walkie-talkie personnel of a certain department in the ...

Problems solved by technology

[0005] As we all know, the dispatching system plays a very important role in some industries. Dispatchers use the dispatching console to contact and allocate telephone users, mobile phone users, and intercom crew resources. The current traditional method is that there are dispatching telephones and intercoms on the dispatching console. When the telephone user needs to be notified, the dispatching telephone is used, and if the intercom group needs to be notified, the intercom call is used. The disadvantages are obvious: there are many dispatching equipment, the operation process is cumbersome, and the interconnection between the telephone user and the intercom group cannot be realized
