Method and apparatus for implementing cluster communication

Abstract

The invention discloses a method and device for implementing group communication. And the method comprises the steps of: A. establishing multicast group according to a mapping relationship between group and multicast group and adding all in-group users in the multicast group; B. initiating calling terminal to send group communication packet; C. group communication implementing device-group communication service node converts the group communication packet into multicast packet, and sends the multicast packet to all the in-group users. And the invention can implement group communication in different networks and between different networks and besides, provide multiple service functions, making in-group users in multiple communication networks able to intercommunicate, and besides, able to conveniently implement multimedia group communication.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for realizing group communication. Background technique [0002] There are many technologies that can support group communication, such as the current group communication, voice chat technology in the network, video conference and so on. [0003] The trunking communication system is a dedicated dispatching communication system, including dedicated command and dispatching communications, which is a communication method that appeared very early. It has developed from one-to-one walkie-talkie, same-frequency simplex networking, different-frequency single (duplex) networking to single-channel one-call-all-response system and further system with selective calling to multi-channel automatic dialing system. In the past ten years, the dedicated dispatching system has developed to a higher level and has become a dispatching system shared by multi-channel...

Problems solved by technology

The problem with the common trunking communication system is that it only provides voice group communication, and it is difficult to provide multimedia group communication. In addition, it can only provide communication for users within the network, and group communication cannot be performed with users using other technologies.

[0004] Conference TV is another group communication technology, which provides image and voice group communication. Its application range is relatively narrow, and it is generally used in special occasions, such as professional users such as finance, police, and companies. The network, the terminal equipment is relatively large in size, there are few mobile-based applications, it takes a long time to establish communication, the real-time performance is poor, and group communication cannot be performed with users using other technologies

[0005] Now in the network, voice and video chat technologies also appear and are widely used, but the disadvantages of these technologies are that there is no dedicated network, and there is no unified and perfect protocol and specification using the existing Internet and existing technologies, which the system can support The business is very simple, and cannot support some professional cluster functions such as scheduling and late access; users are peer-to-peer, and there is no user management function; users and systems are exposed to the public communication network, and the authentication method adopted is relatively simple, which may cause Various unsafe events such as user eavesdropping and user information theft have poor security performance; users of multiple similar technologies cannot communicate with each other, and group communication with users using other technologies is even more impossible
