There is the scene of 2 serving cells with target UE below, i.e., carrier wave polymerization is separated with carrying does not coexist, to this
The scheme of invention is illustrated.In a practical situation, it is not excluded that target UE has the scene of 2 or more cells.?
After energy target UE carrying separation, carrier wave aggregation transfer is also used to isolated carrying.The embodiment of the present invention is equally also fitted
The scene coexisted is separated with carrying with to carrier wave polymerization.
As shown in figure 4, the method that the embodiment of the present invention five switches over includes:
There are 2 cells in base station, and each cell has respective PDCP and RLC entity, and each cell has the end IP
Mouthful.Target UE current transmission mode is carrier wave polymerization, and having rate requirement is 2 DRB of H bps.Target UE
It is S bps in the handling capacity of secondary cell (cell 1).
Step 401: the signal quality value that base station receives secondary cell (cell 1) is higher than the signal quality of main plot (cell 0)
Value not less than the first threshold value time be more than the first duration test report, determine target UE need from carrier wave polymerization
Mode is switched to carrying separate mode.
That is the signal quality value A of cell 1 be greater than cell 0 signal quality value B, and A-B not less than the first threshold value when
Between more than the first duration.
Step 402: base station determines the portfolio that cell 0 and cell 1 need to cut.
Wherein, it includes the portfolio (H- that target UE needs to cut out in cell 0 that cell 1, which needs the portfolio cut,
S)bps。
Step 403: the portfolio and cell 0 and cell 1 that base station needs to cut according to cell 0 and cell 1 are current to be born
Situation is carried, admission control is carried out to cell 0 and cell 1, determines the portfolio that cell 0 and cell 1 allow to cut.
Step 404: base station to the user equipment for needing to cut cell 0 and needs to cut respectively according to the QoS of user equipment
The user equipment of cell 1 carries out priority ranking, determines carrier mode switching priority.Assuming that target UE belongs to cell
The user equipment to sort in 1.
Step 405: base station judgement needs to cut all user equipmenies that priority in cell 1 is higher than target UE
The industry whether portfolio and target UE for needing to cut need the sum of portfolio cut to allow to cut no more than cell 1
Business amount if it is, allowing target UE to carry DRB switches to cell 1, and executes step 406；Otherwise, do not allow
DRB carrying is switched to cell 1 by target UE, and jumps out this process.
Step 406: base station sends carrying separation instruction to target UE, and instruction target UE carries DRB
It is switched to target secondary cell；And it indicates to delete the SCell in carrier wave polymerization to target UE.
Step 407: because the current PDCP and RLC entity of target UE is built upon in cell 0,0 He of cell
The PDCP and RLC module of cell 1 cannot be shared, so PDCP and RLC that target UE is established in base station in cell 1 are real
Body, and delete PDCP the and RLC entity of target UE in cell 0.
Step 408: for optimization system performance, reducing data transmission delay, base station is by the service link of target UE
It is switched to cell 1 from cell 0, to core net transmitting path transition request message, wherein the DRB of target UE carries target
IP address is set as the port IP of 1 processing unit of cell offer.
It should be noted that the sequential relationship that step 406~step 408 is not inevitable, can execute together, can also divide
It does not execute, specific timing can according to need determination.
As shown in figure 5, the method that the embodiment of the present invention six switches over includes:
There are 2 cells in base station, and each cell has respective PDCP and RLC entity, and each cell has the end IP
Mouthful.Target UE current transmission mode is carrying separation, and main coverage cell is cell 0, and secondary cell is cell 1, there is rate
It is required that being 2 DRB of H bps.The data of target UE are sent directly to cell 1 by core net.
Step 501: the signal quality value that base station receives cell 0 is higher than the signal quality value of cell 1 not less than the second thresholding
The time of value is more than the test report of the second duration, and cell 1 meets the condition of the SCell as target UE, really
The user equipment that sets the goal needs to be switched to carrier wave polymerization methods from carrying separate mode.
That is the signal quality value A of cell 0 be greater than cell 1 signal quality value B, and A-B not less than the second threshold value when
Between more than the second duration.
Step 502: base station determines the portfolio that cell 0 and cell 1 need to cut.
Wherein, 2 DRB that the rate of target UE is H are included in the portfolio that cell 0 needs to cut.
Step 503: the portfolio and cell 0 and cell 1 that base station needs to cut according to cell 0 and cell 1 are current to be born
Situation is carried, admission control is carried out to cell 0 and cell 1, determines the portfolio that cell 0 and cell 1 allow to cut.
Step 504: base station to the user equipment for needing to cut cell 0 and needs to cut respectively according to the QoS of user equipment
The user equipment of cell 1 carries out priority ranking, determines carrier mode switching priority.Assuming that target UE belongs to cell
The user equipment to sort in 0.
Step 505: base station judgement needs to cut all user equipmenies that priority in cell 0 is higher than target UE
The industry whether portfolio and target UE for needing to cut need the sum of portfolio cut to allow to cut no more than cell 0
Business amount if it is, allowing target UE to carry DRB switches to cell 0, and executes step 506；Otherwise, do not allow
DRB carrying is switched to cell 0 by target UE, and jumps out this process.
Step 506: base station is sent to target UE increases carrier wave instruction, and instruction increases cell 1 and sets for target user
Standby secondary cell；And the binding relationship of 2 DRB and from cell 0 to target UE instruction delete target user equipment.
Step 507: because the current PDCP and RLC entity of target UE is built upon in cell 1,0 He of cell
The PDCP and RLC module of cell 1 cannot be shared, so PDCP and RLC that target UE is established in base station in cell 0 are real
Body, and delete PDCP the and RLC entity of target UE in cell 1.
Step 508: for optimization system performance, reducing data transmission delay, base station is determined the business of target UE
Link is switched to cell 0 from cell 1.Base station is converted to core net transmitting path and is indicated, wherein the DRB carrying of target UE
Target ip address is set as the IP address of 0 processing unit of cell.
It should be noted that the sequential relationship that step 506~step 508 is not inevitable, can execute together, can also divide
It does not execute, specific timing can according to need determination.
