A private communication method and device for group call service

Abstract

The invention discloses a private communication method and device for a group call service, which are used to realize the private communication among members in the group in the group call service. A private communication method for a group call service provided by the present invention includes: the group call server receives a speaking right application message sent by at least one calling UE that needs to conduct a private call with a target UE in a group of user equipment UEs, wherein, in each The speaking right application message carries the member identifier of the target UE corresponding to the calling UE that sends the speaking right application message in the group to which it belongs; the group call server determines from the at least one calling UE that can talk calling UE, and notify the calling UE that can talk to send a voice stream, after receiving the voice stream sent by the calling UE that can talk, according to the target UE corresponding to the calling UE that can talk to in the group Member ID, which is sent after encrypting the voice stream.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a private communication method and device for a group call service. Background technique [0002] Currently, the group call service carried out in the market is mainly based on the IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) service architecture, and realizes the PTT (Push-To-Talk over Cellular, trunking intercom) function. [0003] The concept of PTT service comes from the walkie-talkie, which is simple and quick for users to use. Similar to the walkie-talkie, it uses half-duplex communication. The call process adopts a half-duplex method, that is to say, when one member of the group is speaking, other members can only answer and cannot speak, similar to broadcasting services. Even if the dispatcher participates in the group call service, other members in the group can only answer when the dispatcher speaks. If the dispatcher wants to talk to a certain...

AI Technical Summary

Problems solved by technology

If the dispatcher wants to talk to a member in the group alone, and does not want others in the group to hear the conversation between them, the current PTT mechanism cannot be realized

The general method is that the two parties who are speaking alone need to withdraw from the group call service, and then initiate a single call, which makes the operation process more complicated and inconvenient for users to use

[0004] To sum up, in the group call service, if one member of the group wants to have a private conversation with another member of the group, the existing PTT mechanism cannot realize it.
