After step S1601, cell set receive the measurement report that UE sends, or cell set is from the angle of RRM, judges that UE needs changing cells;
Step S1602, cell set send resource reconfiguration message by cell-of-origin to UE. The information comprised in resource reallocation message has: Target Cell Identifier (physical label or high level identify or both), UE identifies, frequency point information etc.
After step S1603, cell set send resource reconfiguration message, continuing from cell-of-origin is that UE sends control information on a control channel;
Step S1604, after UE receives resource reallocation message, carrying out resource and heavily join, after UE resource has heavily been joined, UE sends resource to cell set and has heavily joined message.
Step S1605, when cell set receive UE send resource heavily joined message after, cell set stop transmit control message from cell-of-origin to UE;
Step S1606, when cell set receive UE send resource heavily joined message after, start transmit control message on a control channel from target community to UE. On UE is on the control channel of target community, have received control information, automatically interrupts the reception controlling channel on anchor point community, source.
Embodiments provide the mobility management scheme between a kind of cell set, solve the problem not having the switching between cell set at present so that UE can choose in target cell set, it is possible to better support the business of UE, especially high speed business. In mobility management scheme between the cell set of the embodiment of the present invention, it is also possible to carry out switching control by the anchor point community of select target cell set, avoid the complicacy that multiple community participates in switching simultaneously.
The embodiment of the present invention additionally provides the mobility management scheme of a kind of cell set inside, achieve the switching of anchor point community, simplify the movability process complicacy of cell set inside, reduce the interruption time of UE switching, and improve the reliability that signaling receives, thus improve the performance of communication system.
