Two-way call multi-terminal remote video communication method and system under 4G/5G conditions

Abstract

The invention discloses a two-way calling multi-terminal remote video communication method and system under 4G / 5G conditions. Each communication terminal is connected to a signaling server; the signaling server judges the status of the communication terminal; the online and idle communication terminal is added to the answering sequence to establish Communication connection; when a call is initiated, the signaling server connects to the corresponding communication terminal in the answering sequence according to the service setting, and initiates an information exchange. When connecting to a third party, an access request is sent, signaling completes the three-way handshake, and the third party sends streaming data to the other two parties, obtains the streaming data, and establishes a three-way call; multi-party calls and so on. The invention accesses the communication terminal through the signaling server, reduces service steps; can determine the online / offline and busy / idle status of the communication terminal, and the communication status can be controlled by the signaling server, and at the same time realizes the storage of the media stream server.

Description

technical field [0001] The present invention relates to the field of video communication, in particular to a two-way call multi-terminal remote video communication method and system under 4G / 5G conditions. Background technique [0002] Vision is the main way for humans to obtain information, and images and videos play an important role in the interaction between humans and computers. The use of computers and mobile phones for video communication to achieve face-to-face communication experience has been accepted by the majority of people. Therefore, when solving problems and communicating situations, a video platform with video technology as the main technical means is necessary. With the technological level With the development of the development, the interactive mode of data form will be replaced by the full video mode, which will greatly improve the mode and speed of interaction, save the time cost of interaction in an all-round way, and truly return to the original ecolog...

AI Technical Summary

Problems solved by technology

[0005] The existing technology cannot determine whether it is in the online state; secondly, there is only a call mode similar to making a phone call, one party calls one party, and one party calls multiple parties, all of which need to be answered by the called end before the call can be made. In the process of multi-party video communication, there is no concept of management personnel , to control the access status function of one end of video communication; thirdly, the called end must be human-centered, and it is impossible to access and control other IoT devices during a person-to-person call. Finally, the current technical solution, the original data of video communication The storage and playback mechanism is imperfect and cannot meet the needs of different users
