A method for realizing media stream in multicast based on open cluster architecture

Abstract

The invention discloses an implementation method of media stream in global open trunking architecture (GOTA), which comprises: 1) the BSC sets up a forward primary channel and a reverse talk user primary channel on the channel board of each cell in the dispatching zone, distributes a talk user selector progress to connect the two channels of individual cells; 2) the MS of the talk user initiates a group call, after the negotiation between BSS and MS is successful, if the talk user selector progress receives a reverse frame in the reverse talk user primary channel, the talk user selector progress stores the frame in the buffer area after demultiplexing and then performs packet treatment and transfers to the PDS via the PDC, returning the frontward frame; 3) the talk user selector progress receives the frontward frame and then multiplexes with the forward signaling, sends to individual cells in the dispatching zone via the forward primary channel, allowing the listen user to receive. Based on the new resource allocation mode and the new media stream implementation method, the invention efficiently implements the actual share of channel and module resource and increases the system capacity.

Description

A Realization Method of Media Flow in Multicast of Open Cluster Architecture technical field The present invention relates to a professional trunking system GOTA (Global Open Trunking Architecture, open trunking architecture) in a CDMA (Code Division Multiple Access, Code Division Multiple Access) system, and in particular to a method for realizing media flow in GOTA multicast. Background technique Based on the CDMA2000 professional trunking GOTA system, the PTT (PushToTalk) group call service is also called "push to talk" service, which refers to the "point-to-point" and "point-to-multipoint" that uses half-duplex communication to achieve real-time direct connection voice communication. The calling party only needs to press a key, without dialing and waiting for the other party to pick up the phone, the call can be connected immediately, initiate a call to one person or a group of people, and quickly establish a talking group, and only one person can speak at the same tim...

Problems solved by technology

The present invention provides a method for realizing media streams in multicasting with an open cluster architecture to solve the problem that the architecture design of ordinary group calls cannot realize the real sharing of resources such as channels and waste resources
