Bidirectional call multi-terminal remote video communication method and system under 4G/5G condition

Abstract

The invention discloses a bidirectional call multi-terminal remote video communication method and system under a 4G / 5G condition. Each communication terminal is connected with a signaling server; the signaling server judges the state of the communication end; an online communication end in an idle state is added into an answering sequence, and communication connection is established; when a call is initiated, the signaling server is connected with a corresponding communication end in the answering sequence according to service setting, information exchange and signaling are initiated to complete handshake of the two parties, video streams of the two parties are obtained and sent to the opposite party, and communication of the two parties is established; when a third party wants to be accessed, an access request and a signaling are sent to complete three-party handshake, and the third party sends stream pushing data to the other two parties, stream pulling data is obtained and a three-party call isestablished, and and call among multiple parties performs the above operation. The signaling server is accessed to the communication end, so that service steps are reduced; on-line / off-line and busy / idle states of the communication end can be determined, and the communication state can be controlled by a signaling server, and media stream server storage is realized at the same time.

Description

Technical field [0001] The present invention relates to the field of video communications, and more particularly to two-way call multi-end remote video communication methods and systems under 4G / 5g conditions. Background technique [0002] Vision is the main way for human acquisition information, and images play an important role in the interaction of people with computers. With computer and mobile phones to communicate with mobile phone to meet the face-to-face communication experience has been accepted by the people, it is necessary to solve problems and communication situations, video platform with video technology is necessary, with technology level The development, the interaction mode of the data form will be replaced by the full video, will greatly improve the interaction mode and rate, and save the time cost of interacting interaction, truly return to the original interaction. [0003] Most of the existing video communications focuses on all kinds of problems in video c...

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
