Embodiment 1

[0189] This embodiment describes a VBS call initiated by a dispatcher, where the "dispatcher" and "listener" are matched, and there is no "speaker", that is, the first bearer model of the dispatcher and the first bearer model of the listener are adopted. .

[0190] 1. Establish dispatcher bearer

[0191] Such as Figure 4 As shown, when MSC Server receives a VBS / VGCS call, it finds that the group in which the call belongs has defined dispatchers, so it needs to initiate a normal call process to each dispatcher. Therefore, a bearer channel must be established for each dispatcher. Assuming that there are two dispatchers in this VBS / VGCS call, and the call is initiated by dispatcher 1, the MSC Server needs to establish the dispatcher’s access endpoint on the media gateway (it may be the ground circuit connected to the wireless access of the BSC, or It may be the inter-office trunk circuit connected to the PLMN / ISDN network, or the intra-office bearer of other MGWs connected to ...

Embodiment 2

[0207] This embodiment describes another collocation situation of "dispatcher", "speaker" and "listener", that is, adopting the second bearing model of the dispatcher, the third bearing model of the speaker and the second bearing model of the listener , in this embodiment, it is assumed that the speaker initiates a VBS / VGCS call.

[0208] 1. Establish a speaker bearer

[0209] Figure 12 The speaker bearer model of this embodiment is shown. In this speaker bearer model, the access endpoint of the speaker and the conference bridge use different contexts, and the two are connected by two unidirectional internal connections.

[0210] When MSC Server receives a VBS / VGCS call initiated by a VBS / VGCS subscriber, it needs to establish the speaker access endpoint of the VBS / VGCS subscriber and the speaker context including the speaker access endpoint on the media gateway, and In the speaker context, a connection is established to the speaker uplink endpoint and the speaker downlink ...

Abstract

The invention discloses a method for realizing cluster communication services, which reduces the number of endpoints in the conference bridge context. When a caller initiates a cluster call, it includes: establishing the caller's bearer and the conference bridge context, and transferring the caller's terminal through the caller's bearer Connect with the conference bridge context; establish a listener proxy endpoint in the conference bridge context, and the listener proxy endpoint is used to send the voice of the caller to the listener terminal; establish a listener bearer, and pass the listener bearer The endpoint connects to the listener proxy endpoint of the conference bridge context. The invention also discloses a system for realizing cluster communication services, a cluster communication method and a cluster communication system. By adopting the listener proxy in the context of the conference bridge, the number of endpoints in the context of the conference bridge can be reduced, thereby greatly reducing the number of conference mixing resources used in the trunking service.

Description

technical field [0001] The invention relates to a cluster technology, in particular to a method and system for realizing cluster communication services. Background technique [0002] In the trunking communication system based on GSM (Global System for Mobile Communications, Global System for Mobile Communications), VBS (Voice broadcast service, voice broadcast service) and VGCS (Voice group call service, voice group call service) are supported. These services have been widely used in fields such as railways, public security, and firefighting, where large-scale resource scheduling exists. [0003] VBS is a service that transmits the voice (or other signals that can be transmitted through voice coding) sent by service users to all or a group of service users in a geographical area in the GSM mobile network. VGCS is a service that provides a half-duplex call function to a predefined group of users in the GSM mobile network. [0004] The service function of VBS is similar to t...
