Abstract: Disclosed are a method, device and system for maintaining the continuity of a group communication service, for solving the problem in the prior art that the service continuity requirement of group communication may not be satisfied due to the switching of network service from multicast transmission to unicast transmission in an MBSFN domain. The method comprises: when determining that group communication service needs to be switched from multicast transmission to unicast transmission, a GCSE-AS notifies a terminal served by the GCSE-AS that the GCSE-AS is going to switch the group communication service from multicast transmission to unicast transmission; and after receiving a first notification message transmitted by the terminal, the GCSE-AS transmits the group communication service over a unicast carrier established by the terminal for unicast transmission, and stops transmitting the communication service in multicast mode. The terminal has already established a unicast carrier for unicast transmission before the GCSE-AS switches the group communication service from multicast transmission to unicast transmission, thus ensuring the continuity of the group communication service.

Abstract: Embodiments of the present application relate to the technical field of wireless communications, and in particular to a method for configuring uplink semi-persistent scheduling (SPS), a terminal, and a network side device, for use in solving the problem in the prior art of increased service delay caused by long waiting time after the arrival of a service data packet due to the fact that current uplink SPS may not match the arrival time of the service data packet. In the embodiments of the present application, a terminal sends SPS configuration auxiliary information to a network side device, so that the network side device configures uplink SPS information for the terminal according to the received SPS configuration auxiliary information. Because the terminal can send the SPS configuration auxiliary information to the network side device for the network side device to refer when performing uplink SPS configuration, the possibility of occurrence of mismatching between uplink SPS and the arrival time of a service data packet is reduced, so that the waiting time after the arrival of the service data packet is shortened, and the service delay is reduced.
