Step 605:UE connects the pairing sub-district of the cell ID that carries in the reallocation message as newly-increased particular cell with RRC.
If the initial condition of newly-increased particular cell is activated state, then end step.If the initial condition of newly-increased particular cell is a deactivated state, the step below then continuing.
Step 606: network side sends the activation command that is used to activate particular cell to UE.This activation command can be MAC CE (MAC Control Element, medium Access Layer control unit) order.
Step 607:UE activates particular cell according to activation command.
Referring to Fig. 7, when UE deleted particular cell and Serving cell and delete command simultaneously and increases order and be connected reallocation message for RRC in the present embodiment, the method flow of changing particular cell was as follows:
Step 701: network side sends to UE and is used to indicate the RRC of UE deletion particular cell to connect reallocation message.RRC connects reallocation message and also comprises deletion Serving cell indication information, is used to indicate the Serving cell of the identical TDD configuration with particular cell of UE deletion.
Step 702:UE connects reallocation message deletion particular cell according to RRC.
Step 703:UE is according to the Serving cell of the identical TDD configuration with particular cell of deletion Serving cell indication information deletion.
Step 704: network side sends the RRC that is used to indicate UE to increase particular cell to UE and connects reallocation message.RRC connects reallocation message and also comprises increase Serving cell indication information, and indication UE increases Serving cell.
Step 705:UE connects the pairing sub-district of the cell ID that carries in the reallocation message as newly-increased particular cell with RRC.
Step 706:UE increases Serving cell according to increasing the Serving cell indication information.The initial condition of the Serving cell that increases is deactivated state, and is if desired follow-up, and network side can activate newly-increased Serving cell by activation command.
If the initial condition of newly-increased particular cell is activated state, then end step.If the initial condition of newly-increased particular cell is a deactivated state, the step below then continuing.
Step 707: network side sends the activation command that is used to activate particular cell to UE.This activation command can be MAC CE (MAC Control Element, medium Access Layer control unit) order.
Step 708:UE activates particular cell according to activation command.
For example, UE when pre-polymerization sub-district 1, sub-district 2, sub-district 3 and sub-district 4, wherein sub-district 1 is that Pcell, sub-district 3 are Ecell, sub-district 2 and sub-district 4 are Scell, wherein sub-district 1 has identical TDD ascending-descending subframes configuration (as being TDD configuration set 1) with sub-district 2, sub-district 3 has identical TDD ascending-descending subframes configuration (as being TDD configuration set 2) with sub-district 4, and four sub-districts all are in state of activation.Along with moving of UE, UE leaves the coverage of sub-district 3 gradually, perhaps sub-district 3 is owing to be interfered, channel quality descends, the channel quality variation of UE on sub-district 3 then, network side can be known the channel quality variation of sub-district 3 by measuring reported result, and then network side can be adjudicated and be carried out the particular cell change.Network side connects reallocation message by RRC, deletion sub-district 3 and sub-district 4, and with sub-district 5 as new particular cell, sub-district 4 is as new Scell, increase and give UE, wherein, sub-district 5 has identical TDD ascending-descending subframes configuration (TDD configuration set 2) with sub-district 3, sub-district 4.UE receives that this RRC connects after the reallocation message, and deletion sub-district 3 and sub-district 4 increase sub-district 5 then and be new particular cell, and increasing sub-district 4 is new Scell, finishes the particular cell change procedure.And the initial condition of sub-district 5 after increasing newly can activate.If the initial condition of sub-district 5 is deexcitations, then network side can follow-uply activate sub-district 5 by MAC CE signaling.Sub-district 4 newly-increased initial conditions afterwards are deexcitation.It also can be same message that deletion sub-district 3 is connected reallocation message with the RRC that increases sub-district 5.
