Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of resource regulating method and device thereof based on HSDPA.
Background technology
In order to improve the downloading rate of TD (time-division) network (as TD-SCDMA Time Division-Synchronous Code Division Multiple Access Radio Access Network), introduce HSDPA (High Speed Downlink Packet Access among the R5, high speed downlink packet inserts) technology, single carrier can be realized the peak rate of 2.8Mbps.The channel that the TD-SCDMAHSDPA system relates to comprises 5, is respectively:
HS-PDSCH:High-Speed Physical Downlink Shared Channel, High-Speed Physical Downlink Shared Channel is the HSDPA Traffic Channel, is used to carry each UE (subscriber equipment) high level data;
The shared information channel of HS-SICH:High-Speed Shared Information Channel for HS-DSCH high speed descending sharing channel, it is the HSDPA ascending control channel, be used to carry and HS-DSCH (high speed descending sharing channel, the corresponding physical channel is HS-PDSCH) relevant signaling information, these signaling informations can comprise that HARQ confirms/deny to reply the channel quality indication (CQI) of (ACK/NACK), down link;
HS-SCCH:High-Speed Shared Control Channel, High-Speed Shared Control Channel, it is the HSDPA down control channel, the signaling information that is used for carries downlink, these signaling informations can comprise channelization code set, gap information, modulation system, transmission block size, HARQ process number (HARQ Process ID), redundancy versions, new data flag, HS-SCCH cyclic sequence number and UE ID (UE sign) etc.;
The up channel of following of ULA-DPCH:HSDPA is used to carry each UE (subscriber equipment) high level data and the up signaling of following;
The descending channel of following of DL A-DPCH:HSDPA is used for bearing downlink and follows signaling, is used for the physical layer control (comprising synchronously and power control) of up DPCH simultaneously.
As can be seen, the Traffic Channel HS-PDSCH of HSDPA is a shared channel, and promptly this channel resource need be distributed jointly by a plurality of users, and this just needs to consider to adopt which kind of strategy to come the more efficient use channel resource, better meets user's request simultaneously.
Classical resource scheduling algorithm mainly contains in the TD network at present: Max C/I algorithm, RR (poll) algorithm and PF (equitable proportion) algorithm.
Max C/I algorithm is with the channel quality of the UE primary criterion as Resources allocation.Scheduler is at first pressed channel quality to the UE that waits for service, promptly, carrier/interface ratio (C/I between corresponding frame transmission period, or title signal interference ratio) value sorts, the scheduler transmission has the data of the UE of the highest C/I value, up to this UE data queue is empty, perhaps arrives up to the user data that higher C/I value is arranged, perhaps up to there being other re-transmission of higher priority to be scheduled.Such dispatching algorithm is always given the best UE of channel condition with the resource priority allocation, to reach the data throughout that improves the sub-district to greatest extent.Therefore this algorithm does not use in existing network substantially because the fairness of resource allocation is poor.
The RR algorithm is not considered the channel quality of each UE, but adopts the method for Round Robin, is about to all UE and lines up sequence, and for each UE distributes identical sheet service time, current serviced UE will retreat to the sequence end and wait for service next time after this timeslice finishes.The target of this algorithm is to ensure that each user can both obtain certain service time and satisfy the minimum-time lag requirement.This algorithm is better than MaxC/I aspect fairness and algorithm realizes simply at existing network certain application value being arranged.
The PF algorithm is the priority that obtains its resource allocation according to the correlated channels Mass Calculation of each UE, supposes that the throughput of (as a TTI (Transmission Time Interval)) k user in a service time window is T
k, suppose that simultaneously the present channel condition of k user is: (C/I)
kSo, its fairness index is:
As can be seen, have reasonable channel condition and the user's that the service that obtains is less relatively comprehensive priority obtains higherly from formula [1], user's service priority is by fairness index a
kDecision, will at first obtain scheduling so have the user of maximum fairness index.The PF dispatching algorithm has solved contradiction between cell throughout and the service fairness.The advantage that this dispatching algorithm also have to realize easily, response speed is fast etc., be in all packet scheduling algorithms relatively preferably.
The inventor finds in realizing process of the present invention:
Max C/I algorithm has only been considered throughput, though this dispatching algorithm can reach maximum cell throughout, owing to do not consider the fairness problem of resource allocation, thereby causes the bad UE of channel condition can be by long-term blockage;
The RR algorithm can guarantee that each user obtains same scheduling probability, but owing to do not consider user's channel quality in the scheduling process, caused the user of current scheduling might not make full use of shared channel resource, though thereby guaranteed user's fairness, but the sub-district goodput but has been subjected to influence, is difficult to make full use of system resource to reach the higher system capacity;
The PF algorithm is by balanced two factors of throughput of considering channel quality and the current accumulative total of user, reached to take into account in the process of scheduling aspect two of cell throughout and the user fairness.But, because user's fairness mainly is by this factor decision of throughput of the current accumulative total of user, therefore this algorithm only can guarantee from long-term justice (promptly in one long period, each user's Mean Speed is suitable substantially), but can't guarantee the user fairness in the short relatively time, particularly when the user asked higher professional of delay requirement, the existing resources dispatching method can not satisfy these users' business demand.
In sum, the existing resources dispatching method can not be when taking into account throughput, user fairness, satisfies the demand of user to the business that has different delay and require.

Embodiment
Problem at the existence of existing resource scheduling mechanism, the embodiment of the invention is primarily aimed at the multiple services demand of multi-user, foundation to scheduling of resource is expanded, promptly, UE channel quality, UE in existing PF resource scheduling algorithm institute foundation add up on the basis of throughput factor, in the scheduling of resource process, introduce two factors of QoS (service quality) grade and scheduling times, thereby when taking into account user fairness, throughput, guarantee professional QoS demand.
Because the embodiment of the invention has been introduced QoS grade and two factors of scheduling times in the process of scheduling, then corresponding, a kind of computational methods of scheduling priority factor are provided.
If with Q represent UE the QoS grade, represent the number of times that UE is scheduled with Δ t, then in window service time (as a TTI), k user (is expressed as UE
k) aggregated throughput be T
k, UE
kThe number of times that is scheduled is Δ t
k, UE
kThe QoS grade be Q
k, UE
kCurrent channel quality parameter is expressed as (C/I)
k, UE then
kThe scheduling priority factor computing formula be:
Consider the primary and secondary relation of each factor in the scheduling priority factor computing formula (the accumulative total throughput, the scheduling times of UE, the QoS grade that comprise channel quality parameter, UE), promptly, each factor can be revised formula [1] determining the significance level of dispatching priority, obtains
Wherein, α is the weight factor of channel quality parameter, and β is the weight factor of user's aggregated throughput, and γ is the weight factor of scheduling times, δ is the weight factor of QoS grade, can adjust each factor shared proportion in scheduling priority factor according to actual conditions.Formula [3] also can be used as the general formula that calculates scheduling priority factor in the embodiment of the invention, and when the weight factor value in the formula [3] was all identical, formula [3] was identical with formula [2] form of expression.
Consider that carrier/interface ratio (C/I) can use CQI (CQI) to characterize, can revise, that is, wherein carrier/interface ratio (C/I) is replaced with CQI, after formula [3] is revised, obtain formula [2] or formula [3]
According to above-mentioned formula, dispatching priority is directly proportional with the QoS grade, i.e. user's QoS grade high more (higher) as the QoS grade that can set real time business, and dispatching priority is high more, and the possibility that obtains scheduling is high more; Dispatching priority also is inversely proportional to the scheduling times of UE, and promptly the number of times that is scheduled of user is many more, and the possibility that then obtains scheduling is low more.Like this, guaranteed to have in the customer group of identical QoS grade on the one hand, each user can have in throughput under the situation of certain assurance according to scheduling times, channel quality, this three aspect factor of aggregated throughput, can obtain comparatively balanced dispatcher meeting; On the other hand, because the introducing of this factor of scheduling times also will obtain certain dispatcher meeting even can guarantee the junior user of QoS.The QoS of so, then can be comparatively fair assurance customer service.
For the TD-SCDMA network, 3GPP has defined 4 kinds of types of service, and is as shown in table 1:
Table 1, type of service and feature
In the embodiment of the invention, corresponding QoS grade is set, and according to the order of C＞S＞I＞B, corresponding QoS grade reduces successively for the type of service shown in the table 1.Consider that data service is mainly S, I, B three classes in the TD-SCDMA network, so the embodiment of the invention is only considered this three classes business.Because this three classes business is set QoS grade with it according to S＞I＞B mode for the demand difference of time delay, the high more expression of QoS grade point needs priority scheduling more, as the QoS grade is made as 3,2,1 respectively.
Scheduling of resource is undertaken by the equipment (as base station equipment) that network side is responsible for scheduling of resource usually, is the executive agent of scheduling of resource below with the base station equipment in the TD-SCDMAHSDPA network, and the flow process of scheduling of resource is described.
In the scheduling of resource mechanism based on HSDPA, when needs carry out scheduling of resource (as the arrival of scheduling of resource cycle), base station equipment starts HSDPA scheduling of resource flow process, and as shown in Figure 1, this flow process mainly comprises:
When choosing the UE that is scheduled,, choose the quantity UE identical with HS-SCCH quantity from the highest UE of dispatching priority.If the quantity of the UE that current scheduling priority is the highest surpasses HS-SCCH quantity, the UE that then can choose from the highest UE of current scheduling priority with the HS-SCCH equal number dispatches; If the quantity of the UE that current scheduling priority is the highest does not surpass HS-SCCH quantity, then can choose and all have the user of high dispatching priority, treat to choose UE according to dispatching priority order from high to low the dispatched users from remaining again, identical up to the UE total quantity of choosing with HS-SCCH.
In HSDPA mechanism, because base station equipment sends the indication information of down link by HS-SCCH to the UE that is scheduled, therefore, the quantity of the UE that is scheduled can not surpass the quantity of HS-SCCH.
Consider in the practical application that the quantity of each scheduling of resource cycle UE to be scheduled is huge usually, the quantity of the UE that dispatching priority is the highest can surpass HS-SCCH quantity usually, and therefore at this situation, Fig. 2 has provided the flow process of choosing of a kind of UE.
Referring to Fig. 2, in the step 103 for flow process shown in Figure 1, the UE quantity of high dispatching priority surpasses under the situation of HS-SCCH quantity having, and base station equipment is chosen the flow process of the UE that is scheduled, comprising:
Step 203, base station equipment are chosen for the highest UE of current scheduling priority the UE of this scheduling.
In the step 101 of flow process shown in Figure 1, base station equipment can be determined the carrier/interface ratio (C/I) of UE according to the CQI that is used to represent channel quality (Channel Quality Indicator, the CQI) information that each UE reports.In HSDPA mechanism, the CQI feedback of UE side is what to realize by the mode of tabling look-up, be a pre-defined CQI dial gauge (CQI Table), wherein comprise several CQI numberings (CQI Index), the corresponding cover CQI parameter (comprising carrier/interface ratio parameter etc.) of each CQI Index.Like this, UE only need feed back a CQI Index, and base station equipment just can be obtained corresponding C QI parameter (comprising carrier/interface ratio parameter etc.) by this predefined CQI Table of inquiry.
In the step 101 of flow process shown in Figure 1, base station equipment can be added up the scheduling times of each UE ID correspondence according to the UE ID that carries in the downlink signaling information by the HS-SCCH transmission.In HSDPA mechanism, base station equipment use HS-SCCH comes the indication information (comprising channelization code set, gap information, modulation system, transmission block size, UE ID etc.) for the current UE communicating downlink that is scheduled for, therefore, the UE ID that carries in the downlink signaling information of base station equipment by statistics HS-SCCH transmission can count the number of times that is scheduled of UE.
In the step 101 of flow process shown in Figure 1, base station equipment can be according to the type of service shown in Traffic class (type of service) the field indication in RAB (RAB) parameter of UE, and, determine the QoS grade of UE further according to the corresponding relation of defined type of service of the embodiment of the invention and QoS grade.
Preferably, base station equipment is after selecting the UE of this scheduling, and the renewable UE number of times that is scheduled is as each self-correspondingly is used to write down the be scheduled counter of number of times and adds 1 with these UE.Each base station equipment is all carried out aforesaid operations after selecting the UE of current scheduling, when base station equipment need be carried out scheduling of resource, and being used to write down the be scheduled counter values of number of times and just can learning the number of times that each UE is scheduled according to each UE correspondence.
Based on identical technical conceive, the embodiment of the invention also provides a kind of resource allocation device.This resource allocation device is provided with and base station equipment usually.
Referring to Fig. 3, the structural representation of the resource allocation device that provides for the embodiment of the invention, this device comprises: acquisition module 301, dispatching priority determination module 302, resource distribution module 303, wherein:
Dispatching priority determination module 302 is used for dispatching UE channel quality parameter, the number of times that is scheduled, accumulative total throughput, service quality QoS grade separately according to respectively waiting of getting access to of acquisition module 301, determines respectively to wait to dispatch the dispatching priority of UE; In channel quality parameter is under the situation of carrier/interface ratio (C/I), and dispatching priority determination module 302 can calculate the dispatching priority of each UE to be scheduled according to formula [2] or formula [3] or formula [4];
In the said apparatus, acquisition module 301 is obtaining when waiting to dispatch the QoS grade of UE, for each UE to be dispatched that respectively waits to dispatch among the UE, obtain this and wait to dispatch the traffic type information of carrying in the RAB parameter of UE, and determine that according to the traffic type information that gets access to this waits to dispatch the type of service of UE, according to the corresponding relation of predefined type of service and QoS grade, determine to wait to dispatch the corresponding QoS grade of type of service of UE with this.
In the said apparatus, resource distribution module 303 is after choosing scheduling UE, the number of times that is scheduled of the also renewable UE that is selected, obtain respectively waiting to dispatch after this time scheduling of resource the number of times record that is scheduled of UE, so that acquisition module 301 is when scheduling of resource next time, obtain the current number of times record that is scheduled of respectively waiting to dispatch UE, respectively waited to dispatch the number of times that is scheduled of UE.
In the said apparatus, be the order of interactive, Streaming Media type, interactive, back bench-type according to type of service, the QoS grade corresponding with type of service successively decreased successively.In such cases, resource distribution module 303 according to dispatching priority order from high to low, is chosen the to be dispatched UE identical with HS-SCCH quantity when choosing scheduling UE.If what have the highest dispatching priority waits that dispatching UE quantity surpasses HS-SCCH quantity, then resource distribution module 303 is from having waiting to dispatch and choosing the to be dispatched UE identical with HS-SCCH quantity the UE of the highest dispatching priority.
In sum, the embodiment of the invention is introduced and is considered QoS grade and two factors of scheduling times, and can pass through weight factor when determining dispatching priority of users, according to the network operation situation, adjusts each factor shared proportion in priority factors.Based on above thought, embodiment of the invention final body is determined professional QoS grade with the type of service of RAB parameter characterization now; According to user profile contained among the HS-SCCH, add up the number of times that each user is scheduled simultaneously, QoS grade and scheduling times are brought in the computing formula of dispatching priority in attainable mode.Can not guarantee this shortcoming of QoS of survice with respect to the PF algorithm, because the embodiment of the invention is introduced QoS of survice grade and scheduling times in scheduling process, make the user in the process of scheduling, can take into account professional QoS demand, make the high user of QoS can preferentially obtain the chance of dispatching, simultaneously, introduce the number of times of scheduling, also take into account each user's who has considered similar/inhomogeneity business fairness.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
