System and method for realizing intercommunication between ip phone and walkie-talkie system through multicast

Abstract

The invention discloses a system and method for realizing intercommunication between an IP phone and an intercom system through multicasting. The system for realizing intercommunication between an IP phone and an intercom system through multicast includes an intercom application server, an intercom connection server, and an intercom; the intercom application server includes Configuration management module, softswitch communication module, media stream multicast module, control protocol module; Interphone connection server includes media stream multicast transceiver module, control module; The method for realizing IP telephone and intercom system intercommunication by multicast comprises the following steps: Step 1. The user goes off-hook and dials. Step 2. The telephone terminal connects to the soft switch. Step 3. The soft switch communicates with the intercom application server. Step 4. The intercom application server waits for the telephone user to press a button. The invention can realize long-distance intercom and realize seamless communication.

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 ...

[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
