The when that the channel quality of other communities of person being better than the channel quality of Liao Zhe community, can survey to the base station reporting channel of this Serving cell
Amount report.After this cell base station receives measurement report, it may be judged whether need that this UE is switched to other communities and service.As
Really this cell base station determines switching, then need first to send handover request with target handover cell, obtaining target cell base station
After confirmation, this UE to this community sends switching command.After receiving switching command, this UE then disconnects the number with current area
According to communication, starting to initiate connection request to Target cell, wherein connection request includes uplink synchronous process, sends rrc layer connection
Demand signalling processes etc., if connection request is accepted, then UE accesses Target cell success.
Although the connection of UE interface aloft has built up successfully, but in order to ensure the seriality of call, two switched little
The base station in district and the network element of core-network side also need to carry out a series of operation, and this generic operation includes being notified mesh by former Serving cell
Mark Serving cell receives, sends the situation of this UE packet at present, and former base station in service sector has forwarded to base station, target serving district
Be received successful packet, target serving district to core network element mobile management unit (Mobility Management Entity,
Referred to as MME) send data packet transmission path handover request, mobile management unit is to another one core network element gateway
Send bearing modification request etc..Main reason is that more of the communication process of target BS described here and core-network side network element
Having changed the path of the core-network side data transmission to air interface side, main purpose is to ensure after user has switched, permissible
Continue the transmission of legacy data without re-establishing new communication connection, do not result in broken words, the problem such as go offline.
In this alternative embodiment, mobile communication access network network equipment sends community to the mobile communication subscriber terminal in the first community
