Problems solved by technology

[0011] It can be seen that the current method for establishing a shared link in a digital trunking system is likely to cause a large number of call losses or repeated establishment of a shared link when multiple trunking calls are centralized, which seriously affects the quality of trunking services and cannot effectively utilize system resources.

Embodiment Construction

[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] The method for establishing a shared link in a digital trunking system disclosed by the present invention can be applied to the establishment process of a shared A8 link and / or a shared GMP link, wherein the shared A8 link is established for calls of the same trunking group under the same BSC , to establish a shared GMP link for calls of the same cluster group under the same PCF. The A8 and / or GMP shared link establishment process of the method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0049] figure 1 It is a schematic diagram of a processing flow of a preferred embodiment of establishing a shared A8 link in the method of the present invention. Among them, the A8 link is the service link between the BSC and the PCF, and the BSC mainly includes a call control un...

Abstract

The method includes following steps: a) after radio access network (RAN) receives the request for building call connection, decides if the current call is the first call in current trunking group; if yes, then builds the link for current call, and ends the current process; otherwise, goes to step b; b) decides if the trunking group has built link; if yes, the current call message is added into link message, and ends the current process; otherwise, buffers the current call; c) decides if establishment of current link is successful; if yes, the buffered link message is added into the message of link successfully built; if not, then releases the current buffered call.

Description

technical field [0001] The invention relates to the realization technology of the service link in the digital trunking system, in particular to the establishment method of the shared link in the digital trunking system. Background technique [0002] At present, the push-to-talk (PTT, Push-to-Talk) service applied to collaborative work and communication among teams, working groups, and groups refers to real-time point-to-point and point-to-multipoint voice communication. This service adopts half-duplex mode, that is, only one person can speak at the same time, and the calling party can initiate a call to one person or a group by pressing a special key, without dialing and waiting for the other party to pick up the phone, and the call is connected immediately. Thus quickly establishing a conversation group. [0003] When implementing digital trunking services in CDMA, CDMA 2000 or CDMA 1X systems, the trunking service data is transmitted through the packet network, and the mo...
