METHOD AND SYSTEM OF ACQUIRING LISTENER MS INFORMATION AT NETWORK SIDE DURING VGCS/VBS PROCEDURE

摘要

A method for obtaining information of listener mobile' stations in a group call/multicast process in a trunking communication system based on a public network, comprises: designating a dedicated control channel in a multiframe sequence for listener mobile stations reporting information; allocating a sub-channel in the dedicated control channel for a group call/multicast in response to the group call/multicast being established; sending description information of the sub-channel allocated to the mobile stations in the group call/multicast; determining, a position of the sub-channel in the dedicated control channel according to the description information of the sub-channel; determining an access burst (AB) position in the sub-channel corresponding to a listener mobile station based on a mapping relationship between listener mobile stations in the group call/multicast and AB positions in the sub-channel; reporting an AB to a network side via the determined AB position; and obtaining information of the listener mobile station based on the reported AB. With the embodiments of the present invention, the network side is enabled to obtain the information of a listener mobile station at any moment in the group call/multicast process in a trunking communication system based on a public network, which is favorable for the commanding and scheduling in the trunking communication system.
