Public/private network interconnection and intercommunication system and method based on private network clusters and 3G/4G public network

Abstract

The invention discloses a public / private network interconnection and intercommunication method based on private network clusters and a 3G / 4G public network, faces different types of private network clusters and public network users, implements audio / video bidirectional transmission between the private network clusters and the public network users, and solves the problem of audio / video format uniformity from the public network to private networks. The public / private network interconnection and intercommunication method based on the private network clusters and the 3G / 4G public network implements audio / video transmission and display from the private network clusters to public network mobile phone users on one aspect, and achieves functions of transmitting audio / video data into the private networks from different public network users and displaying the audio / video data on a private network wireless handheld terminal on the other aspect.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a method and system for supporting two-way transmission of voice and video between private network clusters and public network mobile phones. Background technique [0002] The trunking communication service refers to the trunking communication network composed of the trunking communication system with technical characteristics such as channel sharing and dynamic allocation, and provides dedicated command and dispatching and other communication services for group users such as multiple departments and units. The trunking is divided into analog trunking and digital trunking, and is currently developing from analog trunking to digital trunking. The current digital trunking mainly includes: TETRA (terrestrial trunking radio system), iDEN (integrated digital enhanced network), GOTA (open trunking architecture), Huawei GT800. [0003] At present, the interconnection and...

AI Technical Summary

Problems solved by technology

[0004] The current public / private network interconnection often has the following shortcomings: (1) Private network clusters usually use a set of custom communication protocols, public network users cannot directly access the private network, and users in the private network cannot obtain public network data

(2) The audio and video data transmitted in the private network usually has a unified format, while the audio and video data formats of the public network are complex and diverse, and cannot directly communicate with the private network
