Step S102, the scheduler of base station obtains data volume to be sent corresponding with terminal in the fixed time, and wherein, terminal is two carrier terminals;
Wherein, the length of fixed time can rule of thumb set, and such as set the fixed time as specifying the dispatching cycle of number (500), the dispatching cycle of usual scheduler is 2ms.Based on this, the process that scheduler obtains data volume can be: this scheduler statistics specifies the number of times having data to be sent in buffer area corresponding with terminal in the dispatching cycle of number; Determine that the to be sent data volume corresponding with terminal accounts for whole ratio of adding up dispatching cycle according to this number of times.
Preferably, the statistic processes of above-mentioned number of times is as follows:
Scheduler determines that the buffer area of the to be sent data corresponding with terminal is N number of, wherein, N be more than or equal to 1 integer; Scheduler is that each buffer area arranges number of times St, t=1,2 ..., N; Wherein, the initial value of St is 0; Within each dispatching cycle of dispatching cycle of specifying number, scheduler travels through each buffer area, determines whether each buffer area has data, if had, the number of times St of correspondence is added 1, if do not had, St is constant.
And the determination of data volume can have two kinds of modes, mode one is: when the number of dispatching cycle reaches appointment number T, base station calculates the non-NULL corresponding with terminal and compares γ
t=St/T, by γ
tin maximum as the non-NULL ratio that have to be sent data volume number of times corresponding with terminal.
Mode two is: when the number of dispatching cycle reaches appointment number T, scheduler calculates the non-NULL corresponding with terminal and compares γ

Embodiment 2
Present embodiments provide a kind of auxiliary carrier wave to two carrier wave and carry out control method, the method can be realized by following module, and these modules can be arranged on base station, and the module be specifically related to is as follows:
1) scheduler module of HSDPA scheduler;
2) the HSDPCCH demodulation module of HSDPA scheduler;
3) algoritic module of HSDPA scheduler;
When 2ms scheduling, first the scheduler module of scheduler can judge whether the HSSCCHorder cycle sending the auxiliary carrier activation/deexcitation of DC arrives, if send the HSSCCHorder cycle to meet, the respective algorithms provided is judged this DCUE is the need of the auxiliary carrier wave of deexcitation according to algoritic module; If the condition sending the auxiliary carrier wave of HSSCCHorder deexcitation meets, then the scheduler module of scheduler can send the corresponding auxiliary carrier wave of HSSCCHorder order notice UE deexcitation to this UE and receive data.
After UE receives mentioned order, whether can receive HSSCCHorder order to scheduler feedback, and stop the data receiver of auxiliary carrier wave in the corresponding moment.
After the HSDPCCH demodulation module of scheduler receives the feedback information of UE, if UE response is positive feedback information, then scheduler can stop the data of auxiliary carrier wave to send; If what UE responded is negative-feedback information, show that UE side does not correctly receive HSSCCHorder, then scheduler can resend this HSSCCHorder order at next Transmission Time Interval (TransmissionTimeInterval, referred to as TTI).The auxiliary serving cell of corresponding activation UE is also corresponding handling process.
See Fig. 2, following step is mainly comprised to the method that the auxiliary carrier wave of two carrier wave controls:
Step S202, scheduler is the number of times that each queue of UE arranges that a variable St has data for recording this queue.
Step S204, every 2ms dispatching cycle, judge whether have data in each queue of UE, if there is no data, perform step S206; If there are data, perform step S208; Repeat step S204, until all queues complete the calculating of St; After statistics St completes, perform step S210;
Step S206, St value remains unchanged, i.e. St=St;
Step S208, has data in current queue, St=St+1;
Step S210, scheduler judges whether the number of times of dispatching cycle reaches T time, if, perform step S212, if not, then do not need to produce HS-SCCHorder for auxiliary carrier activation and deexcitation to UE, after next dispatching cycle arrives, return step S204;
Step S212, calculates the statistic MaxRp of UE, and is set to 0 by St;
Step S214, judges whether to meet MaxRp < k
l, and the auxiliary carrier activation of UE, if so, perform step S216; If not, step S218 is performed;
Step S216, sends the auxiliary carrier commands of deexcitation UE, such as, send the HS-SCCHorder being used for the auxiliary carrier wave of deexcitation;
Step S218, judges whether to meet MaxRp > kp, and the auxiliary carrier wave deexcitation of UE, if so, perform step S220; If not, step S204 is returned;
Step S220, sends and activates the auxiliary carrier commands of UE, such as, send the HS-SCCHorder for activating auxiliary carrier wave;

p;
As Max γ
pbe less than k
l, and when the auxiliary carrier wave of UE is in state of activation, now illustrate that the data volume of UE is fewer within a period of time, now auxiliary carrier wave deexcitation can be fallen, scheduler needs to produce the HS-SCCHorder being used for the auxiliary carrier wave of deexcitation, otherwise proceeds to step G;
As Max γ
pbe greater than or equal to k
h, and when the auxiliary carrier wave of UE is in unactivated state, illustrate that the data volume of UE is larger in cycle T, can activate auxiliary carrier wave by sending order order, scheduler needs to produce the HS-SCCHorder for activating auxiliary carrier wave, otherwise proceeds to step H;
As Max γ
pwhen not satisfying condition above-mentioned, auxiliary carrier wave keeps original state constant, and generation HS-SCCHorder is not used for activating or deexcitation auxiliary carrier wave by scheduler.
According to above judgement, send the order of activation or the auxiliary carrier wave of deexcitation, notice UE processes accordingly.When UE receives HSSCCHorder and can correctly solve, UE can produce positive feedback information to scheduler, and stops in certain moment or start the data receiver of auxiliary carrier wave; When UE correctly can not solve HSSCCHorder, at this moment can produce negative-feedback information to scheduler, at this moment UE does not carry out any process.
After scheduler dispatches HSSCCHorder, the feedback information of UE can be received at 6 TTI.If what base station solved UE response is positive feedback information, then scheduler can stop the scheduling of auxiliary carrier wave simultaneously, the auxiliary carrier wave deexcitation of UE; If what base station solved UE response is negative-feedback information, then scheduler can retransmit this HSSCCHorder order, and maximum retransmission is 3, and after more than 3 times, scheduler can lose this bag.
Now complete a complete handling process.

K
l=15%, k
h=60% (k
l, k
hwhat all arrange is lower, UE can be made more easily to be in two carrier activation state, thus ensure that UE can have higher speed).
Be described with the next two carrier wave UE scheduling in a community below: parameters T=500, k
l=15%, k
h=60%;
The first step: because the scheduler schedules cycle is 2ms, so record the number of times St having data in this pair of carrier wave UEQue buffer area, i.e. St=St+1 when each 2ms;
Second step: judge when every 2ms whether the T cycle arrives, arrives if meet the T cycle, now enters function DPAALGO_SecondCellActiveOrNot and judges whether two carrier wave UE meets the condition sending the auxiliary carrier wave of HSSCCHorder activation deexcitation;
Concrete operations: all communities under traveling through this scheduler, and under finding each community, each couple of carrier wave UE is cached with the number of times St of data in cycle T in Que, the non-NULL obtaining each priority query of UE compares γ
t=S
t/ T, the non-NULL after level and smooth compares γ
p=(1-α) γ
p+ α γ
t(α value is 0.1), γ
pinitial value be that 1, St is re-set as 0, make even sliding after the maximum Max γ of duty ratio
p;
3rd step: as Max γ
pbe less than k
l, and when the auxiliary carrier wave of two carrier wave UE is in state of activation, now illustrate that the data volume of two carrier wave UE within a period of time is fewer, now auxiliary carrier wave deexcitation can be fallen, scheduler needs to produce the HS-SCCHorder being used for the auxiliary carrier wave of deexcitation;
4th step: as Max γ
pbe greater than or equal to k
h, and when the auxiliary carrier wave of two carrier wave UE is in unactivated state, illustrate that the data volume of two carrier wave UE in cycle T is larger, can activate auxiliary carrier wave by sending order order, scheduler needs to produce the HS-SCCHorder for activating auxiliary carrier wave;
5th step: as Max γ
pwhen not satisfying condition with λ, auxiliary carrier wave keeps original state constant, and generation HS-SCCHorder is not used for activating or deexcitation auxiliary carrier wave by scheduler;
6th step: according to above judgement, sends the order order of activation or the auxiliary carrier wave of deexcitation, and the two carrier wave UE of notice processes accordingly.When two carrier wave UE receives HSSCCHorder and can correctly solve, two carrier wave UE can produce positive feedback information to base station, and after 4 TTI, stop or starting the data receiver of auxiliary carrier wave; When UE correctly can not solve HSSCCHorder, at this moment can produce negative-feedback information to base station, at this moment two carrier wave UE does not carry out any process.
7th step: after scheduler dispatches HSSCCHorder, can receive the feedback information of UE at 6 TTI.If what base station solved two carrier wave UE response is positive feedback information, scheduler can stop the scheduling of auxiliary carrier wave simultaneously, the auxiliary carrier wave deexcitation of two carrier wave UE; If what base station solved two carrier wave UE response is negative-feedback information, then scheduler can retransmit this HSSCCHorder order, and maximum retransmission is 3.After more than 3 times, scheduler can lose this order bag.
8th step: after keeping 1s end cycle, returns the first step and starts iterative cycles execution.
Adopt the method for the present embodiment, the auxiliary carrier dispatching of the two carrier wave UE of deexcitation can be activated by HSSCCHorder, achieve the progress that CPC technology is applied in the DC-HSDPA of 3-G (Generation Three mobile communication system), base station can adopt the data of two carrier wave or single carrier to send according to the size of data volume, the down transmitting power of base station can be saved like this and save the battery power consumption of UE, improve HSPA systematic function.
