Abstract
The invention discloses a group call service restoration method used for a broadband trunking communication system, which comprises the following steps. Firstly, a scheduling control center transmits a downlink data packet of a group call to an xGW (Extendable Gateway. Secondly, when the xGW cannot match a group call context corresponding to the downlink data packet in group call contexts being maintained currently, the scheduling control center is informed of abnormity of the group call in the xGW. Thirdly, the scheduling control center transmits a group call restoration message to a mobile management entity (MME) according to the notice. And lastly, the MME executes a reconstruction process of the group call in a core network based on the group call restoration message. With the adoption of the method, a group call service can be quickly restored when errors of the group call context being maintained by the xGW occur..
