For the specific implementation in long term evolution (LTE) system eNB, the business statistics rule of downlink LCH is analyzed, Statistics, to obtain the current down load situation of eNB, and according to the scheduling interval of down load situation adjustment LCH.Preferably, Some LCH only need to be serviced in a certain time interval, it will be able to the QoS for meeting protocol requirement, for this kind of LCH Priority calculating is carried out without each TTI or carries out the processing for the resource that other occupy eNB.Accordingly, it is considered to can basis The LCH historic load situation of each UE, determines this kind of LCH, and take suitable scheduling strategy, it will be able to reach and promote eNB Downlink processing ability, to expand the downlink capacity of eNB.

Based on above-mentioned inventive concept, the present embodiment proposes a kind of mobile Long Term Evolution (LTE) System of raising) system eNB downlink The method of processing capacity operates the certain type of downlink LCH determined in eNB descending scheduling level, can It does not violate the agreement on the basis of QoS, is not scheduled any data to it or its any state is updated, to make it It is not take up the process resource of eNB.

The raising move Long Term Evolution (LTE) System) system eNB downlink processing ability method, as shown in fig. 6, include following step It is rapid:

Step S602: classify to all LCH established under eNB.It specifically includes:

S1: within certain continuous scheduling interval T, the downlink transmitted connection is needed to be defined as no any data I class LCH(is that is, above the second class LCH).

S2: all connections except I class LCH are removed and are defined as B class LCH(that is, above first kind LCH).

S3: I class LCH and B class LCH is respectively put into a scheduling queue, is marked as I queue and B queue.

Step S604: the scheduling interval T of the LCH in eNB is calculated.It specifically includes:

S1: one downlink LCH of scheduling, the difference between frame number when minute book frame frame number and last scheduled, and this is poor Value is added in a variable Tshcd.

S2: in a measurement period, scheduling average value Tavg=Tshcd/ connection for all downlink LCH is calculated Number.

S3: scheduling interval T=Tavg/ Configuration Values K, wherein scheduling interval T is for identifying the current loading condition of system.

Step S606:eNB carries out descending scheduling.It specifically includes:

S1: configuring certain dispatching algorithm according to eNB, and in B queue downlink LCH is chosen to be scheduled.

S2: if current downlink LCH does not have data to need to transmit, Cempty++, otherwise Cempty=0.Cempty is for remembering Record the chance that the LCH is dispatched, however the number that continuous no data is transmitted.Above-mentioned parameter is when connection is established It is initialized as 0.

S3: if Cempty > scheduling interval T, it is deleted from B queue, is put into I queue.After the completion again from B queue A downlink LCH is chosen to be scheduled.

S4: current downlink LCH is dispatched.It completes to the scheduling of current LCH and then from being chosen in B queue under one Row LCH is scheduled, until the bandwidth of current TTI uses until exhausted.

Step S608: downlink LCH switches to B queue from I queue.It specifically includes:

S1: downlink LCH receives data sending request.

S2: if the LCH is currently in I queue, it is deleted from I queue, is put into B queue.

S3: downlink LCH queue finishing switching.

For above-mentioned single downlink LCH processing the step of, suitable for accessing all downlink LCH of eNB.In moving long In the typical commercial environment of phase evolution (LTE) system eNB, even if all downlink LCH have data to need to pass in all TTI When defeated, it can also be handled by above-mentioned scheduling strategy.Some LCH are not when having data frame transfer, so that it may be put into one The i.e. I queue of special queue does not need to waste any processing money for the LCH in I queue when carrying out descending scheduling to eNB Source, so that the downlink processing ability of eNB be effectively promoted.Through the above way in the case where not changing eNB hardware configuration, While all UE offer QoS guarantees to access eNB are provided, the downlink processing ability of eNB can be increased substantially, to mention Rise the power system capacity of eNB.

Step S702, eNB start the scheduling of a frame.

Step S704 goes to step S714 if B queue is sky；Otherwise according to certain preconfigured dispatching algorithm, from A downlink LCH is selected to be scheduled in B queue.

Step S706, if no data needs are scheduled on downlink LCH, Cempty++, otherwise Cempty=0.Its In, Cempty is for recording the chance that the LCH is dispatched, however the number that continuous no data is transmitted, can be with Cempty=0 is initialized as when connection is established.

Step S708, if Cempty > scheduling interval T on downlink LCH, which is taken out from B queue, is put into I team Then column execute step S704.

Step S710 is scheduled the downlink LCH chosen.

Step S712 records Tint=Fcur-Fpre on downlink LCH, accumulates it to overall scheduling discontinuous variable Tshcd+=Tint, while updating Fpre=Fcur on downlink business TC, wherein Fcur is this frame frame number, and Fpre is last time tune The frame number of degree.

Step S714 executes step if the scheduling of current TTI also not up to needs to calculate the calculating cycle P of scheduling interval T Rapid S724.The calculating cycle P of scheduling interval T can be specified the calculating cycle to determine statistics scheduling interval T by system configuration, be used The levels of precision of intervals T calculation is scheduled to eNB in mark.

Step S716 indicates the average scheduling interval of all LCH with Tavg, then in the calculating cycle P of scheduling interval T There is Tavg=Tshcd/Ncon.Wherein, Ncon is the number for being currently accessed all LCH in eNB.

Scheduling interval T=Tavg/ configurable value K can be obtained according to above step in step S718.Wherein, K is eNB configuration Parameter can be used to identify the acceptable loading level of system, if being configured to the larger value, then it is assumed that eNB needs to reinforce descending scheduling Optimization amplitude, to promote downlink processing ability.

Step S720 empties overall scheduling discontinuous variable Tshcd=0.Statistics is re-started to eNB loading condition, with accurate Ground reflects the case where system load.

Step S722 thens follow the steps S704 if that there are also remaining bandwidths is available by current TTI, eNB will continue to it is remaining The downlink LCH of B queue is scheduled.

A frame scheduling of step S724, eNB terminate.
