Alternatively, base station passes through system message for the measurement GAP parameter configuration of cell-level to UE.
Step 33, UE receive group service and unicast service according to measurement GAP parameter, and switch in cell reselection or cellWhen according to measurement GAP parameter carry out different-frequency measure.
Colony terminal UE in connected state or IDLE state is configured according to the measurement GAP in GroupCallConfig messageMeasGapConfig message determines the current measurement GAP parameter for receiving cluster user, specifically, the measurement GAP phase may include moreA measurement GAP subframe, the measurement GAP subframe for meeting formula (2) belong to the survey of the currently received multicast service of UE or unicast serviceGAP subframe is measured, the colony terminal UE in connected state or IDLE state, which can choose, does not receive data in measurement GAP subframe.
GapOffset (GroupID)≤(RFN*10+SFN) MOD GapPeriod (GroupID) &&
GapOffset(GroupID)+6>(RFN*10+SFN)MOD GapPeriod(GroupID)(2)
Wherein, RFN indicates current radio frame number, and SFN indicates current subframe number.
When the colony terminal UE in connected state or IDLE state is when cell reselection or cell switch, need to carry out alien frequencies surveyAmount, the measurement GAP phase that colony terminal UE can be determined at (GapOffset (GroupID), GapOffset (GroupID)+6)Interior carry out different-frequency measure.
