Problems solved by technology

[0003] The transmission of these new high-bandwidth services also brings about a problem. When the cluster responds to hundreds of calls, if these responding terminals are all within the coverage of the same base station, the same media data, such as video data streams, will be transmitted for each terminal. (Video Streaming) will waste a lot of transmission resources, especially the relatively tight backhaul (Backhaul) resources and particularly scarce wireless air interface resources

Abstract

The invention discloses a method for cluster communication. A packet data network gateway establishes a first shared transmission channel from a cluster server to a packet data network gateway; and the packet data network gateway receives a transmission from the cluster server from the first shared transmission channel. The packet data network gateway sends the received data to the cluster terminal through the second shared transmission channel, the third shared transmission channel and the fourth shared transmission channel, so that the same data received by all cluster terminals is The common path of the shared transmission channel established between the cluster server and the cluster terminal is only transmitted once; wherein, the second shared transmission channel is the shared transmission channel from the packet data network gateway to the service gateway; the third shared transmission channel is A shared transmission channel from the serving gateway to the base station; the fourth shared transmission channel is a shared transmission channel from the base station to the cell where the cluster terminal is located.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for trunking communication. Background technique [0002] The trunking communication system is an important branch of the mobile communication system. It is a command and mobilization system in a dedicated mobile communication with dual functions of switching and control. The trunking communication system provides basic business functions such as group calling, speaking right preemption, and dynamic reorganization. Trunking communication system has become an important part of mobile communication [0003] The transmission of these new high-bandwidth services also brings about a problem. When the cluster responds to hundreds of calls, if these responding terminals are all within the coverage of the same base station, the same media data, such as video data streams, will be transmitted for each terminal. (Video Streaming) will waste a lot...
