摘要： A method and system for providing group call service in trunking communication technology are provided. The method includes: allocating an SDCCH by a BSC for an MS; accessing the network and initiating a group call request by the MS; establishing a group call control connection and establishing a group call channel for every cell in group call area; assigning the MS to the group call channel from the SDCCH, and releasing the SDCCH. According to the above solution, only one TCH which is used as group channel, is needed to initiate group call service, no extra TCH is needed for the initiator. In this way, the channel waste in the standard VGCS initiation process is solved.

摘要： A method and system for implementing group call service in network cluster communication technical art, which method comprises: firstly, the base station controller (BSC) allocating a dedicated physical control channel (SDCCH) for a call-initiated mobile station (MS); the call-initiated MS accessing the network and making a request for group call; establishing the control connection of the group call and establishing a group call channel for each cell within the group call area; then, assigning the call-initiated MS to the group call channel from the SDCCH, and releasing the resource on the SDCCH occupied by the call-initiated MS. With the invention, the group call service could be initiated by means of a single channel, and there only needs one TCH channel acting as the group call channel during the call initiation, without the need of any additional TCH available to the initiator, therefore the problem of channel wasting in the standard VGCS initiation mode could be solved.
