Abstract: A method and an apparatus for implementing a group call service. A user equipment of the trunking group call service receives group configuration information and a downlink assignment message and/or an uplink grant message from an evolved cell. The user equipment saves the group configuration information and the downlink assignment message and/or the uplink grant message. If the user equipment is in a group receive state at different points of time, trunking group call service data is saved by sharing a downlink resource, indicated by the downlink assignment message, with another user equipment in the group in a semi-persistent scheduling manner according to the group configuration information.

Abstract: The present invention provides user equipment and a method for ensuring continuous service reception in a wireless network. User equipment (UE) obtains configuration information of a neighboring cell; the UE determines that at least two cells of all cells including the serving cell and the neighboring cell belong to a same area to which a same multimedia broadcast multicast service belongs; and during measurement of a reference signal, the UE combines reference signal measurement values of at least two cells that belong to the area of the same multimedia broadcast multicast service to obtain a combined measurement value, and compares the combined measurement value with a measurement value of another cell, so as to determine whether to perform reselection. Therefore, in a handover determining process, radio signal quality of a single cell is prevented from being underestimated, so that an unnecessary handover procedure is avoided, thereby ensuring quality of a radio signal obtained by UE.
