Abstract
The invention provides a method for simultaneously performing a semi-persistent schedule (SPS) service and a dynamic schedule (DS) service. The method comprises the following steps: (A), if only a present data radio bearer (DRB) bears the SPS service, executing step (B), otherwise, turning to step (C); (B), if only the present time slot is at an SPS repetition period moment and the present time slot has SPS service data to be transmitted, setting the priority of the present DRB to be as SPS to be scheduled, otherwise, executing the step (C); (C), if only the scheduling priority of the present DRB bearer service is higher than the highest scheduling priority of a scheduled user, taking the scheduling priority of the present DRB bearer service as the highest scheduling priority of the scheduled user, otherwise, executing step (D); and (D), scheduling the service of the highest scheduling priority of the scheduled user, and distributing time frequency resources.
Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of method that semi-persistent scheduling (Semi-Persistent Schedule, SPS) is professional and dynamic dispatching (Dynamic Schedule, DS) is professional of carrying out simultaneously.
Background technology
Professional scheduling mode common among the LTE comprises semi-persistent scheduling and dynamic dispatching.The semi-persistent scheduling mode refers in the scheduled transmission process of LTE, the current schedule information of Physical Downlink Control Channel (PDCCH) equipment for indicating user (UE) is passed through in initial schedule in base station (eNB), UE identification is semi-persistent scheduling, then preserve current schedule information, carry out transmission or the reception of this business datum in identical running time-frequency resource position every the fixing cycle.Dynamic dispatching then is to send before the business datum at every turn, and the base station sends the scheduling indication information to subscriber equipment, and subscriber equipment receives business datum at the indicated running time-frequency resource of this scheduling indication information.
At present, in the LTE system, there is the existing semi-persistent scheduling services of same subscriber equipment, the scene of dynamic dispatching business is arranged again.Therefore, divide timing in that the user is carried out resource, need to consider design in semi-persistent scheduling repetition period interval, or when the semi-persistent scheduling repetition period, moment point did not but have data to be transferred, can transmit dynamic service, to reach taking full advantage of resource.
Summary of the invention
The invention provides a kind of method of carrying out simultaneously SPS business and DS business, can improve resource utilization, satisfy these two kinds of business upper line number separately and pass requirement.
The embodiment of the invention proposes a kind of method of carrying out simultaneously SPS business and DS business, and the dispatching priority of SPS business is higher than the dispatching priority of DS business, and the method comprises the steps:
A, judge whether current DRB carries the SPS business, if it is execution in step B; Otherwise, go to step C;
B, judge whether current time slots is on the SPS repetition period moment point and current time slots has the SPS business datum to be transmitted, if, the dispatching priority of current DRB is set to SPS waits to dispatch, otherwise direct execution in step C;
C, judge whether the dispatching priority of current DRB bearer service is higher than this scheduled user's the highest dispatching priority, if, with the dispatching priority of the current DRB bearer service the highest dispatching priority as the scheduled user; Otherwise direct execution in step D;
D, to the scheduled user the business of high dispatching priority dispatch, distribute running time-frequency resource.
Preferably, before the steps A, further comprise: scheduled user's the highest dispatching priority is initialized as 0.
Preferably, before the steps A, further comprise:
A1, traversal are treated scheduled user's Data Radio Bearer DRB, select one as current DRB from the DRB that treats the scheduled user.
Preferably, before the step D, further comprise:
Judge whether current DRB is last DRB of scheduled user, if, execution in step D, otherwise return steps A 1.
Preferably, after the described step D, further comprise:
F, judge whether the business of scheduled user's the highest dispatching priority is that SPS is professional, if the professional corresponding DRB service priority of SPS is set to 0.
As can be seen from the above technical solutions, because the business of DRB carrying is not that SPS is exactly DS, and the priority of SPS will be higher than DS, and when traveling through DRB one by one, that DRB that will priority is high finds out, and is recorded in user's limit priority so.If not in the SPS repetition period, although perhaps the SPS repetition period without the SPS data to be transferred, then the priority of SPS business is turned down, directly process the DS business according to service priority; If enter the SPS repetition period, then again the priority of SPS business is heightened, priority treatment SPS is professional.By with upper type, can realize that the professional and DS business of SPS carries out simultaneously.
Description of drawings
Fig. 1 carries out the handling process schematic diagram of SPS business and DS business when being embodiment of the invention proposition.
Embodiment
Core concept of the present invention is: a user has a plurality of Data Radio Bearer (Data Radio Bearer, DRB), the business of DRB carrying is not that SPS is exactly DS, and the priority of SPS will be higher than DS, so when traveling through DRB one by one, that DRB that will priority is high finds out, and is recorded in user's limit priority.
The dispatching priority of system default SPS business is higher than the dispatching priority of DS business, and the dispatching priority of the dispatching priority of SPS business and DS business is all greater than 0.
Carry out the handling process of SPS business and DS business when the embodiment of the invention proposes as shown in Figure 1, comprise the steps:
Beginning.
Step 101: initialization scheduled user's limit priority is 0.
Step 102: traversal scheduled user's DRB, select one as current DRB from the DRB that treats the scheduled user.
Step 103: judge whether current DRB carries the SPS business, and if it is execution in step 104; Otherwise what current DRB carried is that DS is professional, goes to step 107.
Step 104: judge whether current time slots is on the SPS repetition period moment point, and if it is execution in step 105; Otherwise execution in step 107.
Step 105: judge whether current time slots has the SPS business datum to be transmitted, and if it is execution in step 106; Otherwise execution in step 107.
Step 106: the service priority of current DRB is set to SPS and waits to dispatch.
Step 107: judge whether the service priority of this DRB is higher than user's limit priority of current record, and if it is execution in step 108; Otherwise execution in step 109.
Step 108: the limit priority that this DRB service priority is assigned to the user.
Step 109: judge that whether current DRB is last DRB of this user, if it is carries out 110; Otherwise return execution in step 102.
Step 110: the business that described scheduled user's priority is the highest is dispatched, distribute running time-frequency resource.
Step 111: whether the highest priority traffic of judging the scheduled user is that SPS is professional, and if it is execution in step 112; Otherwise process ends.
Step 112: the professional corresponding DRB service priority of SPS is set to 0.
In the processing procedure of above-mentioned flow process, if not in the SPS repetition period, although perhaps the SPS repetition period without the SPS data to be transferred, then the priority of SPS business is turned down, directly process the DS business according to service priority; If enter the SPS repetition period, then again the priority of SPS business is heightened, priority treatment SPS is professional.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, is equal to replacement, improvement etc., all should be included within the scope of protection of the invention.
