Problems solved by technology

[0003] In the existing PoC service, the PoC control server can only control the data flow of one session, that is, only allows the client to speak or answer in one session, and the control method for the concurrent data flow of multiple sessions has not been disclosed , that is, the client is not allowed to be in multiple sessions at the same time

Embodiment Construction

[0019] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0020] The data flow control mechanism in the PoC service session is divided into two parts: uplink data flow control and downlink data flow control. The downlink data flow is the voice data flow sent to the PoC client, and its control function is implemented on the PoC control server. The upstream data flow is the voice data flow sent by the PoC client to other PoC clients through the PoC control server, and its control function is implemented on the PoC client.

[0021] The downlink data flow control is based on the user-defined session priority of the PoC client, and the level identifies the session priority of the user. For example, there are two types of priority defined for the session, primary and secondary, and the priority of the primary is higher than that of the secondary. Then when two sessions have incomi...

Abstract

The invention relates to a multi-conversation control method, which comprises: receiving downstream data flow of the multiple conversations; and extracting a downstream data flow of conversation with highest priority from the multiple ones to transmit. The invention further relates to a control server, which comprises: a first reception module for receiving the downstream data flows of conversation; a selection module for extracting a downstream data flow of conversation with highest priority from the multiple ones, when the first reception module receives downstream data flows of the multiple conversations; and a transmission module for transmitting the selected downstream data flow of conversation. The invention realizes extracting one conversation data flow from the concurrent multiple ones to transmit, and improves data flow control mechanism in multiple concurrent conversations.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a multi-session control method and a control server based on Push to Talk over Cellular (Push to Talk over Cellular, hereinafter referred to as PoC) based on a cellular network. Background technique [0002] The PoC service is a half-duplex group communication method carried under the General Packet Radio Service (GPRS) network. It is a two-way, instant, multi-party communication method that allows users to communicate with one or more users. . This service is similar to the mobile intercom service, that is, the end user presses a button to talk to a certain end user or broadcast to other end users in a group. After the initial speech is complete, other end users can respond to the speech message. PoC communication is half-duplex, at most one person can speak at a time, and others can answer. [0003] In the existing PoC service, the PoC control server can only cont...
