Description
Technical field
The present invention relates to the communications field, particularly a kind of method of distributing system resource, Apparatus and system.
Background technology
At TD SDMA (Time Division-Synchronous Code Division MultipleAccess, TD-SCDMA) in the system, network side is carrying out resource allocation (resource changing that comprises new access/switching/other algorithm triggers) before at subscriber equipment (UE), need carry out the ordering of priority according to certain criterion to alternative resource (comprising carrier resource and time interval resource), and begin to attempt one by one resource allocation from the highest alternative resource of priority.
Under the prior art, when carrying out resource allocation, travel through and attempt to insert at carrier wave priority query and time slot priority query usually.The account form of carrier wave priority query and time slot priority query has following three kinds:
1, according to default configuration parameter fixing carrier wave priority orders and time slot priority orders are set.
2, according to the power resource ordering, comprising:
At up: side joint Network Based is received broadband gross power (RTWP) or slot interfering signal of time power (ISCP);
At descending: side emission carrier power (TCP) Network Based or many coordinating district interferences algorithm;
Calculate the priority query of carrier wave, the time slot priority query that draws each carrier wave afterwards more earlier by the up-downgoing weighting.For example:
The power factor of supposing carrier wave 1 each time slot is P11, P12, P13, P14, P15, P16, the power factor of carrier wave 2 each time slot is P21, P22, P23, P24, P25, P26, and time slot 1 and 2 is up, and 3-6 is descending, and the more little priority of power factor is high more, suppose that simultaneously the up weighted factor of carrier wave is configured to Beta, then
Carrier wave 1 priority weighting:
P1＝((P11+P12)/2)*Beta+((P13+P14+P15+P16)/4)*(1-Beta)；
Carrier wave 2 priority weightings:
P2＝((P21+P22)/2)*Beta+((P23+P24+P25+P26)/4)*(1-Beta)；
Carrier wave priority is arranged from low to high according to P1 and P2;
Time slot priority in each carrier wave then according to the power factor value of each time slot, is arranged from low to high, does not need to be weighted.
3, sort according to the sign indicating number resource occupation.Wherein, it is high more to take the few more carrier wave priority of yard resource, and simultaneously, it is also high more to take the few more time slot priority of yard resource.
From aforesaid way as can be seen, network side need to consider that the actual loading situation of uplink and downlink is made a strategic decision when UE is carried out resource allocation, no matter but adopt which kind of strategy, all need be based on following two basic principles:
At first, the priority of carrier wave and the priority of time slot are calculated and separate, promptly determine the definite again time interval resource of carrier resource during distributing system resource earlier;
Secondly, when calculating carrier wave priority, be weighted at time slots all in the carrier wave.
Like this, just, can cause the unreasonable of system resource allocation in some cases.For example, most of time slot quality is all fine in certain carrier wave, only has a time slot interference bigger, at time slots all in the carrier wave all the weighting meeting cause the carrier wave priority after the weighting lower; But the real resource demand of UE business may be very little, can be carried on a few fully and disturb on the very little time slot, so, adopt the existing resources method of salary distribution will cause UE can't being assigned on best carrier wave/time slot, thereby the business that influences UE is used, and reduces the service quality of system.

Embodiment
In the existing SDCA algorithm, the system resource ordering was divided into for two steps, promptly carried out the ordering of carrier wave ordering carrying out again time slot earlier.Wherein, carry out in the process of carrier wave ordering, all time slots that comprise at this carrier wave are weighted, thereby obtain the carrier wave priority sequence.A problem of Cun Zaiing is exactly like this, may influence the priority of whole carrier wave, but other time slot interference of this carrier wave be less, and enough admits new business because certain time slot of carrier wave is relatively poor.
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated.
Consult shown in Figure 1, in the embodiment of the invention, be used for distributing system resource system (as, the TD-SCDMA system) comprises several base stations 10 and UE 11, base station 10 is used for the business to be accessed according to UE 11 requests, at each carrier wave, selects disturbance state to meet pre-conditioned N respectively
1Individual time slot, wherein, N
1Carry the required total number of time slot of described business to be accessed in order to characterize, and according to the N that selects at each carrier wave
1Individual time slot is weighted processing to corresponding carrier wave respectively, generates first carrier priority query, and according to described first carrier priority query described business to be accessed is carried access.
Consult shown in Figure 2ly, in the embodiment of the invention, the device (as, base station 10) that is used for distributing system resource comprises screening unit 100, generation unit 101 and load bearing unit 102, wherein,
Screening unit 100 is used for the business to be accessed according to the end side request, at each carrier wave, selects disturbance state to meet pre-conditioned N respectively
1Individual time slot, wherein, N
1In order to characterize the required total number of time slot of the described business to be accessed of carrying;
Generation unit 101 is used for the N that selects according at each carrier wave
1Individual time slot is weighted processing to corresponding carrier wave respectively, generates first carrier priority query;
Load bearing unit 102 is used for according to described first carrier priority query described business to be accessed being carried access.
Based on the said system framework, to consult shown in Figure 3ly, in the embodiment of the invention, the detailed process of the business to be accessed of base station 10 carrying UE 11 requests is as follows:
Step 300: according to the business to be accessed of end side request,, select disturbance state to meet a pre-conditioned N time slot respectively, be designated as N at each carrier wave
1, in order to characterize the required total number of time slot of the described business to be accessed of carrying.
In the present embodiment,, adopt slow dynamic channel allocation (SDCA) algorithm policy, from some time interval resources, filter out satisfactory time interval resource, for example, adopt NB public-measurement mode to filter out the highest N of priority at any carrier wave
1Individual time slot.
On the other hand, in the present embodiment, at any carrier wave, before execution in step 300, in order to reduce follow-up complicated operation degree, can determine the required unit time-slot code channel number of business to be accessed of end side request earlier, and in this any carrier wave time slot corresponding resource, get rid of the time slot that unit time-slot code channel number does not satisfy business demand to be accessed, further, also need to get rid of congested time slot or/and other reserve time slot, wherein, the so-called time slot of reserving can be " a handoff reservation time slot ", if current UE 11 is to switch, then pay the utmost attention to selection " handoff reservation time slot ",, then get rid of " handoff reservation time slot " if current UE 11 is not being switched.
Step 310: according to the N that selects at each carrier wave
1Individual time slot is weighted processing to corresponding carrier wave respectively, obtains carrier wave priority query, in the present embodiment, is called carrier wave priority query 1.
In the present embodiment, when execution in step 310, the N of each carrier wave that base station 10 only filters out in the step 300 of base area
1Individual time slot (comprising uplink and downlink timeslot), adopt the SDCA algorithm respectively corresponding carriers available in the system to be weighted processing, obtain the priority of each carrier wave, again with each carrier wave according to priority sequence arrangement from high to low, and the corresponding timeslot number that participates in weighting of record, thereby generate corresponding carrier wave priority query 1.
On the other hand, after obtaining carrier wave priority query 1, can be optimized adjustment to priority query 1.For example, get rid of congested carrier wave, again for example, according to professional R4/HSPA type, shared channel throughput, FODCA algorithm etc. are revised the carrier wave priority orders; But the weighting time slot of each carrier wave correspondence of record is constant.
Step 320: the business to be accessed according to 1 pair of end side request of carrier wave priority query is carried access.
When execution in step 320, need to carry out resource allocation one by one and attempt according to each carrier wave that carrier wave priority query 1 comprises, the time slot of each carrier wave is only considered the time slot of the corresponding weighting of writing down, with the business to be accessed of carrying end side request; Then finish current flow process if be allocated successfully, if the equal access failure of all alternative resources in the carrier wave priority query 1 (because resource fragmentation causes available code channel to satisfy the demands but actual can't the distribution), then at each carrier wave get rid of respectively cause distributing the time slot of failure after, re-execute step 300-step 320, promptly reselect N respectively at each carrier wave
2Individual time slot, N
1=N
2, and with reference to the N that reselects at each carrier wave
2Individual time slot is weighted processing to corresponding carrier wave respectively, generates carrier wave priority query, is called carrier wave priority query 2, carries access according to the business to be accessed of 2 pairs of end side requests of carrier wave priority query again.
Based on the foregoing description, with any carrier wave is example, if carry access failure according to the business to be accessed of 2 pairs of end side requests of carrier wave priority query, and this carrier wave direction (as, up) all time slots all be excluded, can't find qualified time slot again, then enlarge the number of time slot of carrying business to be accessed on this direction, reduce the code channel number (guaranteeing that total code channel occupancy is constant) of demand on every time slot, and other direction (as, descending) the time slot strategy and the time slot strategy of other carrier waves temporarily do not change, and execution in step 300-step 320 again, certainly, if all do not have in the time of to get rid of time slot in the ascending time slot of above-mentioned any carrier wave correspondence and the descending time slot, also can expand the number of time slot that is used to carry business to be accessed in ascending time slot and the descending time slot simultaneously, be specially: determine ascending time slot in any carrier wave or/and all do not have in descending and can get rid of time slot, the number of time slot that ascending time slot that then will this any carrier wave or/and be used in the descending time slot carries business to be accessed is expanded, and makes the required total number of time slot of the described business to be accessed of this any carriers carry extend to N
3, reduce ascending time slot after the expansion or/and the code channel number that comprises in the descending time slot, and guarantee that total code channel occupancy is constant; Select disturbance state to meet pre-conditioned N at described any carrier wave
3Individual time slot then, selects disturbance state to meet pre-conditioned N respectively at other each carrier waves
2Individual time slot is again according to the N that selects at a certain carrier wave
3Individual time slot, and the N that selects at other each carrier waves
2Individual time slot is weighted processing to corresponding carrier wave respectively, generates carrier wave priority query, is called carrier wave priority query 3, and treats access service according to carrier wave priority query 3 and carry access.For example, before carrier wave A expansion, carry service needed N to be accessed
2=3 time slots (ascending time slot, two descending time slots), and after the ascending time slot expansion to carrier wave A, carry service needed N to be accessed
3=4 time slot (two ascending time slots, two descending time slots), wherein, the code channel number that each time slot comprises in two ascending time slots after the expansion is transferred now, and total code channel invariable number (expanding to the ascending time slot of two 2 code channels as the ascending time slot by one 4 original code channel), then, in carrier wave A, select N
3Individual time slot is weighted, and still selects N2 time slot weighting in other each carrier waves respectively, thereby obtains corresponding carrier wave priority query.
Further, expanded to maximum if can be used for carrying the number of time slot of business to be accessed in above-mentioned any carrier wave in ascending time slot and the descending time slot, still can't find and satisfy the required resource of business to be accessed, then triggered the reduction of speed access process, promptly reduce business to be accessed the resource occupation demand (as, by 2 time slots, 8 code channels of every time slot are reduced to 2 time slots, 4 code channels of every time slot), and restart execution in step step 300-step 320, until successfully inserting, do not repeat them here.In the practical application,, then determine access failure, ending resource allocation flow if the resource occupation demand of business to be accessed has been reduced to and minimumly still can't have been found suitable resource.
With a concrete example above-mentioned flow process is described in detail below.
Consult shown in Figure 4ly, current in the supposing the system have two carrier waves, is called carrier wave 1 and carrier wave 2; Each carrier wave has 6 time slots respectively, is called TS1, TS2, TS3, TS4, TS5 and TS6; The default configuration of supposing R4 business to be accessed is: up 1TS*1SF2, descending 2TS*8SF16, a promptly up time slot, SF2 code channel of every time slot; Descending two time slots, 8 SF16 code channels of every time slot, wherein, so-called SFn code channel is meant that spread spectrum system is the code channel of n.
Wherein, in carrier wave 1 and the carrier wave 2, uplink and downlink timeslot ratio 3: 3, and carrier case is as follows:
All have 2 SF4 to take on carrier wave 1:TS1 and the TS2, TS3 has not had code channel resource; TS1-TS3 disturbs successively and reduces, and TS4-TS6 disturbs successively and raises;
All there are 2 SF4 to take on the carrier wave 2:TS1/TS2, have a SF2 to take on the TS3; TS1-TS3 disturbs successively and raises, and TS4-TS6 disturbs successively and reduces;
Based on above-mentioned resource configuration state, the flow process of then carrying R4 business to be accessed is as follows:
The first round: in carrier wave 1, select TS2+TS4/TS5 weighting (TS3 is excluded owing to the code channel number deficiency), in carrier wave 2, select the TS1+TS5/TS6 weighting; Carrier wave 1 priority is higher after supposing weighting, and then the carrier wave priority query 1 of Sheng Chenging is:
Carrier wave 1 TS2+TS4/TS5
Carrier wave 2 TS1+TS5/TS6
Attempt R4 business to be accessed is carried access according to comprising carrier wave 1 and carrier wave 2 in the carrier wave priority query 1, but because the TS2 of carrier wave 1 and the TS1 of carrier wave 2 all can't insert SF2, epicycle resource allocation failure, beginning second is taken turns;
Second takes turns: the TS2/TS3 that gets rid of in carrier wave 1 (because last round of TS2 resource allocation failure, the TS3 code channel is all occupied), in carrier wave 2, get rid of TS1 (because last round of TS1 resource allocation failure), again after selecting, in carrier wave 1, select TS 1+TS4/TS5 weighting, in carrier wave 2, select the TS2+TS5/TS6 weighting; Carrier wave 2 priority are higher after supposing weighting, and then the carrier wave priority query 2 of Sheng Chenging is:
Carrier wave 2 TS2+TS5/TS6
Carrier wave 1 TS1+TS4/TS5
Attempt R4 business to be accessed is carried access according to comprising carrier wave 1 and carrier wave 2 in the carrier wave priority query 1, but because the ascending time slot of two carrier waves still can't insert SF2, epicycle resource allocation failure, beginning third round;
Third round: because all ascending time slots of carrier wave 1 all distribute failure, then the resource requirement that changes UE at carrier wave 1 is 2TS*1SF4, and carrier wave 2 is constant, after then reselecting, in carrier wave 1, select the TS1/TS2+TS4/TS5 weighting, in carrier wave 2, select the TS3+TS5/TS6 weighting; Carrier wave 2 priority are higher after supposing weighting, and then the carrier wave priority query 3 of Sheng Chenging is:
Carrier wave 2 TS3+TS5/TS6
Carrier wave 1 TS1/TS2+TS4/TS5
Attempt R4 business to be accessed is carried access according to comprising carrier wave 1 and carrier wave 2 in the carrier wave priority query 1, insert successfully at carrier wave 2, then access slot is TS3+TS5/TS6.
The carrier wave priority list and the time slot priority list of prior art separate, and be as follows:
Carrier wave priority list: carrier wave 2, carrier wave 1
The time slot priority list of carrier wave 1: up (TS1, TS2), descending (TS6, TS3, TS4, TS5)
The time slot priority list of carrier wave 2: up (TS2, TS1), descending (TS3, TS5, TS6, TS4)
And in the embodiment of the invention, the priority list of carrier wave and time slot is unified, as,
The resource prioritization tabulation: carrier wave 2 (up TS3, descending TS5 and TS6), carrier wave 1 (up TS1 and TS2, descending TS4 and TS5) like this, has just been determined the priority query of alternative carrier wave and time slot simultaneously after weighting, improved operation efficiency.
In sum, in the embodiment of the invention, the number of time slot that the base station is required according to the business to be accessed of end side request, when carrier weighting, alternative time interval resource is screened, pick out disturbed condition and meet a pre-conditioned N carrier wave, and after weighting, determine the priority query of alternative carrier wave and time slot simultaneously, treat access service according to this priority query again and carry access, like this, just combine the real resource demand of the business to be accessed of end side request, optimized the resource allocation of system side, can provide end side with best in theory resource, thereby promote quality of service.
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.
