The method of a kind of resource distribution that the embodiment of the present invention provides, with the carrier frequency point of the network equipment as foundation,
Community is divided, obtains at least two region, and determine that each region may be allocated target resource
Probability, the resource allocation probability in the most each region, determine according to the resource allocation probability of regional afterwards
Current time needs the target area of allocated target resource, and is the terminal distribution target money in target area
Source.It is compared in prior art the user channel quality because being in cell edge poor, and makes user wait
Long period could obtain higher priority, thus obtains the chance that the network equipment is its Resources allocation, this
Invention by carrying out region division to community, and determines the resource allocation probability in each region, makes each region
Interior terminal is owned by the chance being scheduled within a certain period of time.Also imply that, be in the use of cell edge
Family can be according to the resource allocation probability in this region by network equipment Resources allocation.So, it is to avoid place
User in MPS process edge cannot be assigned to the situation of resource for a long time.Therefore, above-mentioned distribution is used
The method of resource can be effectively improved the fairness of scheduling of resource, thus improves the use being in MPS process edge
Family is assigned to the probability of resource, also ensures that the proper communication of the user being in MPS process edge.
In order to ensure in resource allocation process, it is possible to be that the terminal being in diverse location provides the most liberally
Source is distributed, and in an implementation of the embodiment of the present invention, according to certain rule, community can be carried out district
Territory divides.Therefore, on the basis of implementation as shown in Figure 1, it is also possible to be embodied as shown in Figure 2
Implementation.Wherein, step 101 is according to the carrier frequency point of the network equipment, by little zoning corresponding for the network equipment
It is divided at least two region, step 1011 can be implemented as to step 1013:
1011, carrier frequency point is arranged in order according to order from big to small, obtains f1 to fn.
Wherein, f is used for representing carrier frequency point, and n is the positive integer more than 1 and less than or equal to 6.
The carrier frequency point of the network equipment is sorted from high to low, it is thus achieved that carrier frequency point set A, A={f1 > f2 ...
fn-1>fn}.Wherein, due at LTE (English: Long Term Evolution, Chinese: Long Term Evolution)
In Rel-10 agreement, a network equipment is at best able to be polymerized 6 member carriers, including a main carrier and 1
To 5 auxiliary carrier waves, therefore, n is the positive integer more than 1 and less than or equal to 6.
1012, with the network equipment as the center of circle, the covering radius of each carrier frequency point is determined.
Due to the corresponding coverage of each carrier frequency point, therefore, it is possible to the network equipment as the center of circle, really
The covering radius of fixed each carrier frequency point correspondence coverage, the covering radius of the most each carrier frequency point.Wherein,
Covering radius can represent with set R, specially R={R1 < R2 ... Rn-1 < Rn}, n is more than 1 and to be less than
Or the positive integer equal to 6.
1013, according to covering radius, community is divided into a border circular areas and at least one annular region.
With the network equipment as the center of circle, R is radius, can obtain n concentric circular.According to this n concentric circular by little
Zoning is divided into a border circular areas and border circular areas corresponding to n-1 annular region, specially f1, and f1 with
The annular region formed between the covering edge of f2 correspondence overlay area, in like manner can obtain, fn-1 with fn is corresponding to be covered
The annular region formed between the covering edge in cover region territory.
The method of a kind of resource distribution that the embodiment of the present invention provides, is being divided at least two region by community
During, it is possible to the network equipment as the center of circle, according to carrier frequency point order from big to small, determine successively
The covering radius of each carrier frequency point, covering radius determined by basis, is divided into a circle by community afterwards
Shape region and at least one annular region.It is compared in prior art the subscriber channel because being in cell edge
Second-rate, and the long period could obtain higher priority to make user wait, thus obtain the network equipment
For the chance of its Resources allocation, the present invention can be effectively improved the fairness of scheduling of resource, and raising is in little
The user at covering edge, district is assigned to the probability of resource, it is ensured that be in user normal at MPS process edge
In the case of communication, by the basis of carrier frequency point, community is carried out the classifying rationally in region, makes difference
Carrier frequency point involved between region is different, thus is guaranteed at the data transmission matter of the terminal of same area
Measure similar.Namely by region is divided, it can be ensured that during resource is distributed, it is contemplated that
Terminal for unlike signal transmission quality carries out resource distribution, also avoid to transmit second-rate be positioned at little
The terminal at covering edge, district cannot get resource for a long time, thus promotes resource distributional equity further.
In order to ensure in resource allocation process, each region can be more fair for other regions
Be assigned to resource, in an implementation of the embodiment of the present invention, can be big according to the area in region
The little resource allocation probability determining each region.Therefore, on the basis of implementation as shown in Figure 1,
It is also implemented as implementation as shown in Figure 3.Wherein, step 102 determines the resource distribution in each region
Probability, can be implemented as step 1021 and step 1022:
1021, the area in each region, and the area of community are determined.
The region obtained is divided, it may be determined that the area in each region and the area of community according to step 101.
On the basis of region division result obtained by according to step 1011 to 1013, it may be determined that each region
Area S.Such as: the area of f1 correspondence border circular areas is S1, S1=π R12；The corresponding overlay area of f1 with f2
The area covering the annular region formed between edge is S2, S2=π (R22-R12)；Fn-1 with fn is corresponding to be covered
The area covering the annular region formed between edge in region is Sn, Sn=π (Rn2-Rn-12).Wherein, little
The gross area in district can be expressed as π Rn2。
1022, the ratio of the area in each region Yu the area of community is defined as resource allocation probability.
The allocation probability P of the target resource in each region, is specifically as follows circle intra domain user corresponding for f1
Resource allocation probability is P1, P1=R12/Rn2；Formed between the covering edge of the corresponding overlay area of f1 with f2
The resource allocation probability of annulus intra domain user is P2, P2=(R22-R12)/Rn2；By that analogy, fn-1 and fn
The resource allocation probability covering the annulus intra domain user formed between edge of corresponding overlay area is Pn,
Pn=(Rn2-Rn-12)/Rn2。
The method of a kind of resource distribution that the embodiment of the present invention provides, it is possible to dividing a cell at least two
Behind region, determine the resource allocation probability of each community according to the area in each region and the ratio of plot area.
It is compared in prior art the user channel quality because being in cell edge poor, and it is longer to make user wait
Time could obtain higher priority, thus obtains the chance that the network equipment is its Resources allocation, the present invention
Be that each region determines a resource allocation probability according to area ratio so that the size of resource allocation probability with
The size of each region occupied area is directly proportional, say, that the user in the region that area is big is assigned to
The probability of resource is relatively large, and the probability that the user in the region that area is little is assigned to resource is relatively small,
Improve user in regional with this and be allocated the fairness of resource.Therefore, above-mentioned Resources allocation is used
Method can be that the user being in MPS process edge determines a resource allocation probability, it is to avoid is in community and covers
The user at lid edge cannot obtain resource for a long time, thus the user that raising is in MPS process edge is allocated
To the probability of resource, further increase resource distributional equity.
In order to ensure in resource allocation process, target area has preferable fairness and bigger handling capacity simultaneously,
In an implementation of the embodiment of the present invention, can be according to the priority of target area internal object terminal
It distributes target resource.Therefore, on the basis of implementation as shown in Figure 2, it is also possible to be embodied as such as figure
Implementation shown in 4.Wherein, perform step 104 be target area in terminal distribution target resource it
Before, it is also possible to first carrying out step 105, step 104 can be implemented as step 1041:
105, the priority of target area internal object terminal is determined.
Divide the region obtained according to step 101, MPS process marginal area and non-MPS process limit can be divided into
Edge region.According to region division result, can cover corresponding with fn for the covering edge of fn-1 correspondence overlay area
The annular region formed between edge that covers in cover region territory is defined as MPS process marginal area, by other districts
Territory is defined as non-MPS process marginal area.
It is in the terminal in MPS process marginal area, owing to jitter may can migrate to other at any time
Community.Therefore, during performing step 105, to the terminal being in MPS process marginal area, if
Cannot ensure that this terminal has certain stability, then need not determine the priority of this terminal, the most not for being somebody's turn to do
Terminal distribution target resource.For being in the terminal in MPS process marginal area, this end can be determined by
End RSRP on each carrier frequency point (English: Reference Signal Receiving Power, in
Literary composition: Reference Signal Received Power), and by each RSRP of this terminal respectively compared with the handoff threshold of base station,
If all RSRP that this terminal is corresponding and the difference of base station handoff threshold, it is satisfied by threshold requirement, i.e. this difference
More than or equal to this threshold value, it is determined that this terminal is target terminal；If this terminal exist at least one RSRP with
The difference of base station handoff threshold, is unsatisfactory for threshold requirement, it is determined that this terminal is not target terminal, i.e. this end
End does not possess can be for the condition of its distribution target resource.For being in the end in non-MPS process marginal area
End, is all defined as target terminal.
The process of the distribution priority of target resource is determined for target terminal each in current target region
In, priority can be determined according to equation below:
P (t)=ri (n, s)/Ri (s)
Wherein, moment t is used for representing current time, and (n, when being s) slot s, i-th user is at carrier frequency for ri
Instantaneous transmission speed on some fn, Ri (s) is the average biography of i-th user in the certain time before slot s
Defeated speed.
1041, for the highest terminal of target terminal medium priority or priority more than the terminal distribution target of threshold value
Resource.
In embodiments of the present invention, threshold value can be preset according to historical experience value by staff,
Not limiting at this, concrete set-up mode is not limited only to above-mentioned setting means.

It is also implemented as implementation as shown in Figure 5.Wherein, perform step 1041 be in target terminal preferentially
After the highest terminal of level or priority are more than the terminal distribution target resource of threshold value, step 106 can be performed:
106, according to target terminal in the transfer rate of current time, and average transmission within a certain period of time
Speed, updates the priority of target terminal.
Wherein, the cut-off time of certain time is current time.
Moment t be that priority is the highest or priority more than the target terminal distribution target resource of threshold value after, update
The priority of target terminal.Wherein, update principle can be such that
Ri (s+1)=(1-1/Tc) * Ri (s)+(1/Tc) * ri (n, s) * [α (i)+β (i)]/2
Wherein, Tc is a TTI (English: Transport Time Interval, Chinese: transmission time
Interval) time window length, α (i) is that service rate ensures the factor, and β (i) is the grade of service factor.
In embodiments of the present invention, GBR (English: Guaranteed Bit Rate, Chinese: ensure bit rate)
