Description

Method, server and client for PoC user self-selecting call object

technical field

The invention relates to telephone communication technology, in particular to a method, a server and a client for PoC users to self-select a call object.

Background technique

Significant developments in mobile communication technology and the expansion of mobile communication networks have led to a dramatic increase in the number of services and applications that utilize cellular phones. At present, since mobile phones can support IP multimedia, this makes it easy to implement the PoC (Push to talk over Cellular) function on mobile phones. PoC refers to the half-duplex voice service realized by VoIP (Voice over Internet Protocol) technology based on the packet domain bearer of the mobile cellular network.

The half-duplex voice service originated from the trunking communication technology. It was first used on the walkie-talkie. The user initiates a half-duplex voice session or applies for the right to speak in the session by pressing the button. After obtaining the right to speak, the user can start talking. When one party speaks, Other members can only answer.

Based on IP technology, when PoC services are implemented, network resources are occupied only when PoC users are speaking, instead of occupying network resources during the entire session, which can use mobile communication network resources more effectively than circuit-switched voice services. At present, the basic PoC service functions only include simple intercom, group and user information, etc. As hundreds of millions of mobile users use telecommunication services, people's demand for PoC services is also increasing.
