Embodiment two
The embodiment of the present invention two provides a kind of method that packet is split, and described method includes following step
Suddenly：
When UE has accessed PCC or Pcell and has SCC or Scell to be also activated, eNB is true
Determine the ratio of speed of the current UE within last moment or period on different districts/carrier wave, Ran Hougen
According to the ratio of speed of the current UE within last moment or period on different districts/carrier wave to the UE
In subsequent time or packet to be scheduled is split in the period.It is determined that current UE is in last moment
Or the eNB can ought with fixed proportion before the ratio of speed on different districts/carrier wave in the period
Preceding UE packets to be scheduled are split.
Wherein, the ratio of described speed can be the ratio of the speed after correction.
For there is not scheduled surplus resources in the cell or carrier wave that are polymerize after fractionation, eNB is then by these
Surplus resources distribute to the UE being aggregated on this cell or carrier wave.
Described eNB determines that current UE is flat on different districts/carrier wave within last moment or period
The ratio of equal speed, is specifically included：ENB first determines dispatchings of the UE on each cell/carrier,
The scheduling resource that described dispatching includes UE channel quality and taken, and scheduling times；eNB
The scheduling resource of channel quality and occupancy further according to UE, and scheduling times determine the UE in the cell
Speed on/carrier wave, determines UE on different districts/carrier wave finally according to the speed on each cell/carrier
Speed ratio.
If the UE channel qualities that last moment dispatches on some cell/carrier are M, the resource of occupancy
For N, then it is X that can obtain the last bit numbers dispatched of the UE according to agreement, in conjunction with the UE
The scheduling times Y counted on the cell/carrier in nearest 1s, it may be determined that go out the UE the cell/
Speed on carrier wave is Z=X*Y bit/s, can similarly determine speed of the UE on other cell/carriers
Zn bit/s, n represent the numbering of cell/carrier.Finally according to speed of the UE on different districts/carrier wave

If UE on some cell/carrier on average channel quality in a period be M, it is average
The resource of occupancy is N, then according to being averaged that agreement can obtain dispatching every time in a UE upper period
Bit number is X, in conjunction with the UE on the cell/carrier on the scheduling times that count in a period
Y, it may be determined that go out speed of the UE on the cell/carrier, needs exist for count in the time cycle
Scheduling times Y conversions are the scheduling times Y ' of UE in 1s, then determine the UE in the cell/carrier again
On Mean Speed be Z=X*Y ' bit/s.UE being averaged on other cell/carriers can similarly be calculated
Speed Zn bit/s, n represent the numbering of cell/carrier.Finally according to the UE on different districts/carrier wave
Mean Speed determines the ratio of Mean Speed.
If there are not scheduled surplus resources on some cell/carrier, these surplus resources are distributed to
The UE of scheduling.
Technical scheme is described further with reference to example.
Example 1, UE Index=10 UE is initially accessed, and activates two carrier waves：
Step 1, eNB carries out UE packets to be scheduled balanced fractionation between 2 carrier waves；
Step 2, eNB determines Mean Speed of the current UE in last moment on different districts/carrier wave
Ratio；
The channel quality of Ue last moments on carrier 1 is 22, and the resource of occupancy is 32, then according to association
The bit number that view can obtain UE the last time scheduling is 14688bit, and the UE is nearest on the carrier wave
Scheduling times 2 in 1s, it may be determined that go out the speed of the UE on carrier 1 for 14688*2=29376
bit/s。
The channel quality of Ue last moments on carrier 2 is 16, and the resource of occupancy is 40, then according to association
The bit number that view can obtain UE the last time scheduling is 12216bit, and the UE is nearest on the carrier wave
Scheduling times 3 in 1s, it may be determined that go out the speed of the UE on carrier 2 for 12216*3=36648
bits/s。
Then the ratio of speed of the UE on carrier wave 1 and carrier wave 2 is 29376：36648=1：1.25.
Step 3, eNB is when a next packet to be scheduled arrives, according to 1：1.25 ratio will be treated
The packet of scheduling is split between carrier wave 1 and carrier wave 2.
Example 2, UE Index=10 UE is initially accessed, and activates two carrier waves：
Step 1, eNB is split UE packets to be scheduled between 2 carrier waves；
Step 2, eNB determined average speed of the current UE within a upper period on different districts/carrier wave
The ratio of rate；
Average channel qualities of the Ue in carrier wave 1 within a upper period is 24, and the resource averagely taken is
40, then the average number of bits that can obtain dispatching every time in a UE nearest period according to agreement is
The scheduling times 10 that 21384bits, the UE are counted on the carrier wave in a nearest period, by the time
The scheduling times conversion of statistics is the scheduling times 10*2=20 of UE in 1s in section, finally obtains the UE
Mean Speed on the carrier wave is 21384*20=427680bits/s.
Average channel qualities of the Ue in carrier wave 2 within a upper period is 10, and the resource averagely taken is
20, then the average number of bits that can obtain dispatching every time in a UE nearest period according to agreement is
The scheduling times 30 that 3112bits, the UE are counted on the carrier wave in a nearest period, by the period
The scheduling times conversion of interior statistics is the scheduling times 30*2=60 of UE in 1s, finally obtains the UE at this
Mean Speed on carrier wave is 3112*60=186720bits/s.
Then the ratio of speed of the UE on carrier wave 1 and carrier wave 2 is 427680：186720=2.29：1.
Step 3, eNB is when once, dispatching cycle arrives, according to 1：1.25 ratio is by number to be scheduled
Split according to bag between carrier wave 1 and carrier wave 2.
Example 3, UE Index=10 UE is initially accessed, and activates two carrier waves, as shown in Figure 3,
Comprise the steps of：
Step 1, eNB by UE packets to be scheduled between 2 carrier waves with 1：2 ratio is entered
Row is split；
Step 2, eNB determined average speed of the current UE within a upper period on different districts/carrier wave
The ratio of rate；
The average channel qualities of Ue on carrier 1 in the nearest speed fractionation cycle are 10, average to take
Resource be 40, then can be obtained dispatching every time in the UE nearest speed fractionation cycles according to agreement
Average number of bits be 6200bits, what the UE was counted on the carrier wave in the nearest speed fractionation cycle
Scheduling times 10, the scheduling times counted in the speed fractionation cycle are converted as the scheduling times of UE in 1s
10*5=50, finally obtains Mean Speeds of the UE on the carrier wave for 6200*50=310000bits/s.
The average channel qualities of Ue on carrier 2 in the nearest speed fractionation cycle are 10, average to take
Resource be 20, the resources left for averagely having 10RB in measurement period on the carrier wave should in measurement period
There are 5 scheduling UE on carrier wave, then update the Ue and averagely take resource and be：20+10/5=22, then basis
The average number of bits that agreement can obtain dispatching every time in the UE nearest speed fractionation cycles is
The scheduling times 40 that 3496bits, the UE are counted on the carrier wave in the nearest speed fractionation cycle, will
Speed splits scheduling times 40*5=200 of the scheduling times conversion of statistics in the cycle for UE in 1s, finally
Mean Speeds of the UE on the carrier wave is obtained for 3496*200=699200bits/s.
Then the ratio of speed of the UE on carrier wave 1 and carrier wave 2 is 310000：699200=1：2.26.
Step 3, eNB is corrected to carrier wave 1 and the ratio of the speed on carrier wave 2, because initial
State eNB by UE packets to be scheduled between 2 carrier waves with 1：2 ratio is split,
So the carrier wave 1 and the ratio of the speed on carrier wave 2 after correction are (1+1)：(2+2.26)=2:4.26；
Step 4, eNB is when once, dispatching cycle arrives, according to the ratio of the Mean Speed after correction
2:4.26 are split packet to be scheduled between carrier wave 1 and carrier wave 2.
