Embodiment Construction

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] Common voice and data services in the BSS system and PTT single call services can only use unicast to forward media streams, while PTT group call forward media streams need to be distributed in a multi-level multicast manner in order to improve The capacity of the BSS system. The SDU supports the soft handover function of the mobile terminal, so the SDU actually has the multicast function to the BSC media plane gateway. A kind of forward media flow sending method provided by the present invention preferably adds multicast table on BSC media plane gateway, BTS media plane gateway, is used for saving multicast group member address, so that BSC media plane gateway, BTS media plane gateway also Possess the multicast function, so as to realize the three-level multicast function of the forward media flow of the BSS system (three-le...

Abstract

The invention discloses a method for sending a forward media stream. The method comprises the following steps of: establishing a base station controller media interface gateway multicast table on a selection/distribution unit when a group call is established, adding a base station controller media interface gateway address related to cells in a group call dispatching cell into the multicast table, searching the base station controller media interface gateway multicast table by the selection/distribution unit after the selection/distribution unit receives the forward media stream, and sending the forward media stream to all base station controller media interface gateways listed in the multicast table. The invention also discloses a system for sending the forward media stream. By the multistage multicast method, link resources among the media interface gateways and of the Abis are saved, and the problem of the capacitance of a base station system (BSS) caused by the limited media interface resources of the BSS is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and system for sending forward media streams. Background technique [0002] Trunking communication refers to a dedicated dispatching communication method, including dedicated command and dispatching communication. During use, trunking users can join calls at the same time, and calls are made in simplex or half-duplex mode. [0003] For example, the CDMA trunking communication system is developed based on CDMA 2000, which combines CDMA technology with a dedicated dispatch communication system. In addition to all the business functions of the CDMA 2000 system, the system also has the function of cluster dispatching, which can realize fast connection, adopts half-duplex communication mode, and realizes "point-to-point" and "point-to-many" direct connection in real time. "Point" voice communication, supports one-to-many group call service, and also supports one-to-one sin...
