Third embodiment of the invention, on the basis of above-mentioned two embodiments, the present embodiment for by each LTE delineation of activities for group service and this two type of common LTE business, introduce two methods example, technical scheme be described in more detail.
This two methods example all can at use scheduling collection of illustrative plates, realize on the basis of group service and LTE traffic scheduling, by dynamic conditioning scheduling collection of illustrative plates index, i.e. dynamic conditioning LTE and colony dispatching subframe ratio, utilize interface-free resources to greatest extent, improve power system capacity.
Application example one:
The dynamic adjustment process of the scheduling collection of illustrative plates of this application example, as shown in Figure 3, as follows:
Step 1, configuration dynamic dispatching collection of illustrative plates.In the system of group service and common LTE business common network, when allocating cell, whether configuration dynamic dispatching collection of illustrative plates is enable, and configures initial atlas index.
In scheduling collection of illustrative plates, to dispatch collection of illustrative plates according to 10 subframes to define different scheduling collection of illustrative plates indexes, for FDD standard, the collection of illustrative plates of scheduling collection of illustrative plates index 1 correspondence is defined as: { 0,0,1,0,0,0,0,0,0,0}, if first subframe is the 0th work song frame, the 2nd work song frame be designated 1, represent the 2nd work song frame scheduling group service, all the other subframes be designated 0, represent the common LTE business of all the other subframe schedulings.The subframe of scheduling group service is called cluster subframe, and the subframe of dispatching common LTE is called common LTE subframe, and in scheduling collection of illustrative plates index 1, the proportioning of cluster subframe and common LTE subframe is 1:9.The collection of illustrative plates of scheduling collection of illustrative plates index 2 correspondence is defined as: { 0,0,1,0,1,0,0,0,0,0}, the proportioning of so dispatching cluster subframe and common LTE subframe in collection of illustrative plates index 2 is 2:8, and scheduling collection of illustrative plates index 2, relative to scheduling collection of illustrative plates index 1, adds a cluster subframe.For the scheduling collection of illustrative plates definition under each service subframe proportioning of TDD standard roughly the same.
Step 2, dynamic collection of illustrative plates adjustment judgement.First, judge that whether district dynamic collection of illustrative plates is enable, if not enable, the scheduling collection of illustrative plates corresponding according to initial atlas index is dispatched; If enable, then enter step 3;
Step 3, the business satisfaction statistics of common LTE business and group service is carried out in base station, and according in dynamic collection of illustrative plates adjustment cycle, the business satisfaction of group service and the business satisfaction of common LTE business are adjudicated, determine whether to increase or reduce cluster subframe, thus adjustment scheduling collection of illustrative plates index, base station, in next adjustment cycle, is dispatched according to new scheduling collection of illustrative plates index.
Concrete, if cluster GBR traffic satisfaction is Trunk_GBR_Satisfy, cluster NGBR business satisfaction is Trunk_NGBR_Satisfy; Common LTE GBR traffic satisfaction is LTE_GBR_Satisfy, and common LTE NGBR business satisfaction is LTE_NGBR_Satisfy.Business satisfaction=business throughput/business demand amount.
If court verdict is Flag, 01 represents increase cluster subframe, and 10 represent reduction cluster subframes, and 00 expression remains unchanged.
Dynamic collection of illustrative plates adjustment cycle arrives, then carry out adjustment judgement in accordance with the following steps:
If a is Trunk_GBR_Satisfy>=100%, LTE_GBR_Satisfy<100%, then putting Flag is 10, otherwise enters b;
If b is Trunk_GBR_Satisfy<100%, LTE_GBR_Satisfy>=100%, then putting Flag is 01, otherwise enters c;
If c is Trunk_GBR_Satisfy>=100%, LTE_GBR_Satisfy>=100%, then enter d, otherwise to put Flag be 00;
If d is Trunk_NGBR_Satisfy>=100%, LTE_NGBR_Satisfy<100%, then putting Flag is 10, otherwise enters e;
If e is Trunk_NGBR_Satisfy<100%, LTE_NGBR_Satisfy>=100%, then putting Flag is 01, otherwise enters f;
If f is Trunk_NGBR_Satisfy>=100%, LTE_NGBR_Satisfy>=100%, then enter g, otherwise to put Flag be 00;
If g has group service, and do not have common LTE business, then putting Flag is 01, otherwise enters h;
If h has common LTE business, and does not have group service, then putting Flag is 10, otherwise enters i;
If i colony dispatching residue RB sum is more than 1 subframe, then putting Flag is 10, otherwise to put Flag be 00;
Step 4, after collection of illustrative plates index changes, if increase cluster subframe, the common LTE business of SPS scheduling in the cluster subframe needing deexcitation to increase; If reduce cluster subframe, the group service of SPS scheduling in the cluster subframe needing deexcitation to reduce.Such as: if collection of illustrative plates is by { 0,0,0,0,0,0,0,0,0,0} is adjusted to, and { 0,0,1,0,0,0,0,0,0,0} then needs the common LTE business of SPS scheduling on deexcitation 2 work song frame.
In this application example, by setting steps g, h, the situation of interface-free resources waste can be there is for the method for prior art, such as: when only there is single business, subframe so for group service or LTE traffic scheduling can not be used for LTE traffic scheduling or group service scheduling, sub-frame allocation as much as possible, by the flexible adjustment to scheduling collection of illustrative plates index, uses to the business of the single type existed by this application example.
Application example two:
This application example is except business satisfaction, also introduce RB utilance and carry out the demand size of evaluation assignment to interface-free resources, whether the cluster subframe that business satisfaction and RB utilance can reflect or LTE subframe can meet current traffic scheduling situation, are all to utilize interface-free resources to greatest extent.
If court verdict is Flag, 01 represents that cluster subframe increases, and 00 represents constant, and 10 represent the reduction of cluster subframe.
If RBRatio_T is cluster subframe RB utilance, RBRatio_L is LTE subframe RB utilance;
GBR_Satisfy_T is cluster GBR traffic satisfaction, and GBR_Satisfy_L is LTE GBR traffic satisfaction;
NGBR_Satisfy_T is cluster NGBR business satisfaction, and NGBR_Satisfy_L is LTE NGBR business satisfaction;
RBRatio_Tlow is cluster subframe RB utilance low threshold, and RBRatio_Thigh is cluster subframe RB utilance high threshold; RBRatio_Llow is LTE subframe RB utilance low threshold, and RBRatio_Lhigh is LTE subframe RB utilance high threshold;
Thr_NGBR_High is the thresholding of the ratio of cluster and LTE NGBR business satisfaction;
The dynamic adjustment process of the scheduling collection of illustrative plates of this application example, namely the adjustment judging process of cluster subframe is as follows:
If step S1 RBRatio_T<=RBRatio_Tlow and RBRatio_L>=RBRatio_Lhigh, then reduce cluster subframe, putting Flag is 10, otherwise enters step S2.
If step S2 RBRatio_T>RBRatio_Thigh and RBRatio_L<RBRatio_Lhigh, then increase cluster subframe, putting Flag is 01, otherwise enters step S3.
If step S3 RBRatio_T>RBRatio_Thigh and RBRatio_L>RBRatio_Lhigh, then judge the business satisfaction of cluster and common LTE business, otherwise do not adjust.
Judge that the process of the GBR traffic satisfaction of cluster and common LTE business is as follows:
If GBR_Satisfy_T<Thr_GBR and GBR_Satisfy_L>=Thr_GBR, then increase cluster subframe, putting Flag is 01;
If GBR_Satisfy_T>=Thr_GBR and GBR_Satisfy_L<Thr_GBR, then reduce cluster subframe, putting Flag is 10;
If step S4 GBR_Satisfy_T>=Thr_GBR and GBR_Satisfy_L>=Thr_GBR, then judge the NGBR business satisfaction of cluster and common LTE business further, otherwise do not adjust.
Judge that the process of the NGBR business satisfaction of cluster and common LTE business is as follows:
If NGBR_Satisfy_T/NGBR_Satisfy_L<Thr_NGBR_Low, then increase cluster subframe, putting Flag is 01;
If NGBR_Satisfy_T/NGBR_Satisfy_L>Thr_NGBR_Hig is h, then reduce cluster subframe, putting Flag is 10.
