Description
Technical field
The present invention relates to the communications field, particularly relate to a kind of for the handoff technique to subscriber equipment under CoMP pattern.
Background technology
In LTE system, CoMP(Coordinated Multi PointTransmission/Reception, coordinate multipoint send/receive) often occur in the edge of Liang Ge community, and from anchor community and cooperation cell Received signal strength, more easily switching in such a case, may be even reciprocating switching (ping-pong).But the switching under CoMP is very complicated.
First, need to determine whether to be applicable to switching, in the handover, user will exit CoMP pattern, then eNodeB(Evolved Node B, i.e. evolved Node B, the base station name in LTE) again will judge whether described user is applicable to CoMP, and reconfigure the user CoMP information of anchor community and cooperation cell.When reciprocating switching, handoff procedure is more complicated, and this Complicated Flow for CoMP user switching will lower efficiency, and consumes more as the ENodeB resource of lead code (preamble) etc.
The current method switched for solving CoMP user is that user starts normal switching flow when measurement report display meets switching threshold.After switching completes, user promptly changes anchor community and cooperation cell, and then it will switch to use CoMP to dispatch.
Fig. 1 shows to the schematic flow sheet that subscriber equipment under CoMP pattern switches in a kind of prior art, and concrete steps are as follows:
Step 1: if meet switching condition, then cell-of-origin sends switching command to Target cell;
Step 2: after Target cell receives switching command, Target cell will arrange user's context and assigning lead codes (preamble) and interim-CRNTI(temp-CRNTI) etc.;
Step 3: after Resourse Distribute completes, Target cell will prepare to complete by notification source cell merge.Meanwhile, Target cell will notify that its needs of CoMP manager carry out switching scheduling;
Step 4: when subscriber equipment (UE) receives handover information RRCReconfiguration, UE sends with the msg1 of lead code distributed with linking objective community;
Step 5: when Target cell detects msg1, Target cell starts TA and detects and TPC flow process, and the msg2 comprising TA and TPC information is sent to UE;
Step 6:UE is from Target cell receiving random access response (RAR, i.e. above-mentioned msg2), and it is synchronous with Target cell and send msg3 message RRCReconfigurationComplete to Target cell;
Step 7: Target cell receives msg3, and has switched.Notification source community, Target cell and CoMP manager are to carry out the switching of anchor community and cooperation cell;
Step 8:CoMP manager performs switching, and reshuffling anchor community is cooperation cell, and to reshuffle cooperation cell be anchor community;
Step 9: after the switching of anchor community and cooperation cell completes, CoMP manager will perform the normal consistency under CoMP pattern.
The problem of the program is when switching between cell-of-origin and Target cell, and the switching between anchor community (and cooperation cell) is also in generation.Therefore, the complicated and poor efficiency of these two flow processs is performed.But in fact, because cooperation cell coordinates with served user equipment with anchor community, the cooperation cell therefore as Target cell also can be synchronous with described subscriber equipment even without msg1 and msg2.
