Abstract

The invention discloses a transmission method and a device of a media stream. The method comprises the following steps: determining a plurality of calling terminals with voice rights and a plurality of called terminals without voice rights through a cluster control function TCF module; acquiring an uplink media stream of each of a plurality of calling terminals having voice rights; according to apredetermined mixing rule, mixing the uplink media streams of each calling terminal to obtain a plurality of mixed media streams; transmitting a plurality of mixed media streams to a plurality of calling terminals having voice rights and a plurality of called terminals not having voice rights. The invention solves the problem that broadband trunking communication B-TrunC does not support multi-user speech at the same time in each call, resulting in inefficient communication technical problems.

Description

technical field [0001] The present invention relates to the technical field of trunking communication, in particular, to a method and device for transmitting media streams. Background technique [0002] The broadband trunking communication (B-TrunC) system based on LTE technology defines a broadband trunking enhancement technology based on TD-LTE technology, and supports various trunking services such as single call and group call. figure 1 It is a structural diagram of a broadband trunking communication system according to the prior art, such as figure 1 As shown, the system composition of broadband trunking communication B-TrunC is as shown in the figure below, including: DC, broadband trunking core network TCN (wherein, broadband trunking core network TCN includes: eHSS and xGW, TCF / TMF, eMME), the following also includes: eNB And T-eNB, eNB is wirelessly connected with LTE data terminal, T-eNB is wirelessly connected with cluster terminal, among them, TCF is responsible...
