Abstract

The method comprises: packing the speak-right control information into the expansion region of RTP (real-time transmission protocol) frame; b) user end makes the interaction of speak-right control information with the PTT server through RTP; c) according to the speak-right control information, the speak-right is transferred between user ends. By the invention, a transmission port occupied by RTCP (real-time transmission control protocol) for transmitting the speak-right control information can be reduced.

Description

technical field [0001] The invention relates to the field of digital trunking communication, in particular to a speaking right control method and a communication method of a digital trunking system. Background technique [0002] The digital trunking system is an important branch of the mobile communication system. It is a dedicated mobile communication system in which multiple users share a group of wireless channels and use these channels dynamically. At present, the main methods for realizing digital trunking services in TD-SCDMA (Time Division Synchronous Code Division Multiple Access) system are group calls and individual calls, where an individual call is to establish a separate data channel between the user terminal and the media server , each data packet sent from the media server can only be transmitted to one user terminal. Group call is on a network built with multicast technology, which allows routers to copy data packets to multiple channels at one time and send...
