Embodiment
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, and obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Shown in Figure 1, the embodiment of the present invention provides a kind of resource regulating method schematic flow sheet, and the method is performed by base station, and implementation method comprises particularly:
Step S101, determines the initial schedule priority of described terminal according to dispatching algorithm.
Step S102, determines according to the information of terminal the configuration scheduling priority that described terminal is corresponding, the dispatching sequence of described configuration scheduling priority reflection different terminals.
Step S103, determines the final dispatching priority of described terminal, carries out scheduling of resource according to described final dispatching priority according to the initial schedule priority of described terminal and described configuration scheduling priority.
In step S101, existing dispatching algorithm at least comprises following several: the service quality scheduling algorithm of polling algorithm, max carrier to interference scheduling algorithm, business and proportional fair scheduling.
Wherein, the basic thought of polling algorithm thinks that the dispatching priority of all users is all equal in community, and all users are periodically scheduled, and ensures that each user probability that is scheduled is identical.Such as, there are 3 users in community, adopt the situation that the scheduler of polling algorithm can not be considered position residing for each user and be scheduled before, just simply according to certain fixing dispatching sequence, as terminal 1, terminal 2, terminal 3, terminal 1, terminal 2, terminal 3 ... periodically dispatch each user.Therefore polling algorithm is the fair maximized dispatching algorithm of a kind of typical pursuit, implements fairly simple.
The basic thought of max carrier to interference algorithm is at each scheduling instance, scheduler can carry out the sequence of carrier/interface ratio to needed dispatched users, then scheduler can the top-quality user of selective channel be dispatched, such guarantee system always can be dispatched to best user, ensure the maximization of systematic function, resource utilization is the highest.Visible, max carrier to interference algorithm is a kind of dispatching algorithm pursuing maximizes system performance, within dispatching cycle all Resourse Distribute to the best terminal of signal quality, ensure that throughput of system can reach maximum.
Consider that polling algorithm ensure that the fairness between user, but loss system throughput; Max carrier to interference algorithm obtains maximum throughput of system, but loses fairness.Therefore, in order to obtain certain trading off between these two kinds of algorithms, prior art also teaches a kind of proportional fair algorithm.The method while the high-speed data service demand as far as possible meeting the good terminal of channel quality, the also experience of the terminal that giving consideration to channel quality condition is bad.The basic thought of this algorithm is the ratio considering momentary rate and long-term Mean Speed when selecting user, and exploitation right weight values adjusts different user simultaneously, reaches the object simultaneously taking into account systematic function and Consumer's Experience.
Based on above dispatching algorithm, therefrom select one, in order to determine the initial schedule priority of described terminal.Such as, LTE proportional fair dispatching method is selected, according to following steps determination initial schedule priority:
Step one, the information reported according to bottom obtains the total signal power ratio of customer service, and utilizes shannon formula to calculate the instantaneous spectrum efficiency of user;
Step 2, calculates user's QOS (QoS) weight according to type of service;
Step 3, calculates the throughput weight of user according to average throughput;
Step 4, calculates the initial schedule priority of user according to above-mentioned steps one, two and three acquired results.
In order to meet the problem of carrying out scheduling of resource according to the peculiar information of user terminal, the embodiment of the present invention proposes a kind of configuration scheduling priority, and described configuration scheduling priority comprises:
The configuration scheduling priority that described terminal is corresponding is determined according to the mark in the information of described terminal; Or,
According to the corresponding relation of the time period in the information of described terminal and configuration scheduling priority, determine the configuration scheduling priority that time period belonging to current time is corresponding; Or,
According to the corresponding relation of the position in the information of described terminal and configuration scheduling priority, determine the configuration scheduling priority that the position at the current place of described terminal is corresponding.
Particularly, first the mark of terminal is obtained, it can be such as IMSI (international mobile subscriber identity) number etc., the network connecting request information that base station receiving terminal sends, and therefrom obtain terminal iidentification, then find out the priority factor of terminal corresponding to the identification information of terminal in the special dispatch list pre-set from base station, or base station arranges higher priority factor to the specific identifier obtained according to demand, described priority factor constitutes configuration scheduling priority.
Further, in order to reach at Different periods, the object that the up-downgoing scheduling of resource situation of terminal is different, can consider to carry out distinguishing the process arranging priority factor for different time sections.The priority factor that such as can pre-set 9:00 ~ 11:00 corresponding is during this period of time higher, when base station to obtain in this community after the end message connected during this period of time, the unified priority factor arranging terminal corresponding to 9:00 ~ 11:00, described priority factor constitutes configuration scheduling priority.
Consider in practical application the occasion that there is the such as high-level meeting Room, at this moment just need to give the higher priority factor in the high-level meeting Room to obtain data processing rate faster.Particularly, the position that locating terminal is current, finds corresponding base station or radio frequency remoto module (RRU) according to the position of terminal, and for this base station or RRU arrange corresponding priority factor, described priority factor is configuration scheduling priority.
Certainly to be above combined based on can combine use or three of any two kinds of methods in the configuration scheduling priority method to set up of terminal identification information, temporal information or positional information simultaneously, will the priority factor that draws to be combined as configuration scheduling priority.
Such as, 6 users are had to be terminal 0 respectively under supposing current area, terminal 1, terminal 2, terminal 3, terminal 4, terminal 5, wherein terminal 5 belongs to advanced level user, therefore arranging priority factor corresponding to each terminal is 1.0, 1.0, 1.0, 1.0, 1.0, 1.5, because terminal 3 is in the high-level meeting Room, therefore again arranging priority factor corresponding to each terminal according to position difference is 1.0, 1.0, 1.0, 1.2, 1.0, 1.0, consider the time period of 9:00 ~ 11:00, terminal 1 and terminal 2 is only had to carry out data access, now arranging priority factor corresponding to each terminal according to the time period is again 2.0, 2.0, 1.0, 1.0, 1.0, 1.0, the most all priority factor correspondences are multiplied, show that configuration scheduling priority corresponding to each terminal is 2.0, 2.0, 1.0, 1.2, 1.0, 1.5.
It should be noted that, the information of described terminal includes but not limited to the above-mentioned information such as position, time, mark provided, and the peculiar information of other terminal is also included, and will not enumerate at this.
After determining initial schedule priority and configuration scheduling priority, initial schedule priority is multiplied with configuration scheduling priority and obtains the final dispatching priority of described terminal, then according to described final dispatching priority, determine the sequencing that terminal is scheduled, with the terminal making terminal that final dispatching priority is high lower than final dispatching priority by priority allocation resource; And/or,
According to described final dispatching priority, determine that the resource that terminal is assigned with is how many, be assigned with more resource to make the high terminal of the final dispatching priority terminal lower than final dispatching priority.
The effect done like this is, the high terminal of final dispatching priority, by priority allocation resource, thus can complete data processing as early as possible, preferably, the terminal that final dispatching priority is high both by priority allocation resource, also can be assigned with more resource, thus complete data processing fast.
