The certain customers' equipment for calculating the resource requirement ratio is determined as edge customer equipment.In this manner it is possible to make it possible to edge use
Equipment ratio shared in all user equipmenies in family is in preset proportional region, and then can control being capable of edge customer
The quantity of equipment also would not be side as being only determined user equipment according to the geographical location of user equipment in the prior art
Edge user equipment or central user equipment, and then there is the excessive situation of edge customer equipment.Meanwhile the embodiment of the present invention
In, it is corresponding due to can control the quantity of edge customer equipment, also can control centre's user equipment quantity, make
Obtaining center frequency-band resource can also obtain more adequately utilizing, and improve the utilization rate of resource, and then guarantee user equipment communication
Process is carried out in time, so that the usage experience of user is more preferably.
Technical solution provided in an embodiment of the present invention is introduced with reference to the accompanying drawing.During following introduction, it incite somebody to action this
The technical solution that inventive embodiments provide is using for scene shown in Fig. 1, and the application scenarios of certain embodiment of the present invention are not
It is limited to this.
Fig. 2 is referred to, one embodiment of the invention provides a kind of method for distributing resource for user equipment, and this method can lead to
The device provided in an embodiment of the present invention for user equipment distribution resource is crossed to execute, the device of resource should be distributed for user equipment
It such as can be base station.The process of this method is described as follows:
Step 201: all user equipmenies base station covered by the signal quality sequence from low to high of user equipment into
Row sequence.
Step 202: since all user equipmenies the minimum user equipment of signal quality, successively add up user equipment pair
The resource requirement answered, and the corresponding resource requirement of cumulative user equipment is successively calculated in the resource requirement of all user equipmenies
Shared ratio.
Step 203: if the cumulative corresponding resource requirement of M user equipment institute in the resource requirement of all user equipmenies
The ratio accounted for is less than or equal to preset ratio threshold value, it is determined that the corresponding M user equipment of cumulative resource requirement is edge use
Family equipment, wherein M is positive integer.
Step 204: for edge customer equipment allocations of edge band resource.
In the embodiment of the present invention, although only showing a base station in Fig. 2, but it should being appreciated that, which be can be together
One or more base station in frequency networking；And in Fig. 2 being one of user equipment in the base station range,
The user equipment can be one of them in above-mentioned M user equipment, be also possible to the other users in addition to M user equipment
One of them in equipment.
Base station in the embodiment of the present invention can be any one base station, user equipment shown in Fig. 1 and be also possible to Fig. 1
In any one user equipment.Certainly, the quantity of base station and position etc. are only used for illustrating in Fig. 1, in practical applications for
The quantity of the base station of identical networking and position are not limited.Likewise, the quantity of user equipment and position etc. is also only in Fig. 1
For illustrating, in practical applications also with no restrictions for the quantity of user equipment and position etc..
By being able to use by the user equipment of user equipment and adjacent cell in serving cell in ICIC
Edge band resource difference come the interference that inhibits identical networking to generate, therefore in embodiments of the present invention, in order to inhibit with frequency
The interference that networking generates, it is also desirable to be preferably the user equipment allocations of edge band resource farthest from base station.Therefore, base station is first
All user equipmenies in the base station range can be ranked up according to signal quality descending sequence.Wherein,
Signal quality can reflect out distance of the user equipment at a distance from base station.Signal quality can be by being used to indicate user equipment
The parameter of communication quality determine, RSRP of these parameters for example including user equipment, or may include the letter of user equipment
Road quality instruction (Channel Quality Indicator, CQI) perhaps may include the SINR of user equipment or may be used also
To include the Block Error Rate (Block Error Ratio, BLER) of user equipment, it is, of course, also possible to include other possible parameters,
The embodiment of the present invention is without limitation.Wherein, if signal quality determines that base station can by the RSRP or CQI of user equipment
To require user equipment to report RSRP or CQI, such as user equipment RSRP or CQI etc. can be sent to base by dedicated signaling
It stands, or RSRP or CQI can also be sent together when sending other information to base station, such as RSRP can follow measurement report
(Measurement Report, MR) is reported together, and CQI can pass through Physical Uplink Control Channel (Physical Uplink
Control Channel, PUCCH) it reports.If signal quality is determined by the SINR or BLER of user equipment, base station can be with
SINR or BLER is determined according to the data sent in the communication process before user equipment.
Such as the user equipment for including in Fig. 1, if the sequence that base station is descending according to the RSRP of user equipment
It is ranked up, then the sequence after the user equipment sequence in Fig. 1 are as follows: 6 < user equipment of user equipment, 4 < user equipment 3 <
5 < user equipment of user equipment, 2 < user equipment 1.
After to the sequence of all user equipmenies, base station the minimum user of signal quality can be set from all user equipmenies
Standby to start, successively add up the corresponding resource requirement of user equipment, and successively calculates the corresponding resource requirement of cumulative user equipment
The shared ratio in the resource requirement of all user equipmenies.
Specifically, requirement of the different user equipmenies to resource is different.Such as the non-guaranteed bit speed in LTE system
Rate (Non-Guaranteed Bit Rate, N-GBR) user equipment only requires to require to minimum guaranteed rate；And guarantee ratio
The indexs such as time delay, rate, Block Error Rate are had high standard by special rate (Guaranteed Bit Rate, GBR) user equipment,
The resource that the user equipmenies of requirements at the higher level needs is then more, that is to say, that its resource requirement of the user equipment of requirements at the higher level is
It is higher.For example, in cell 0 shown in Fig. 1, the quantity of the resource of the request of 1~user equipment of user equipment 6 successively can be with
It is 25,10,15,20,15,15, then the quantity of the resource to be requested of all user equipmenies is 25+10+15+20+15+15=
100。
In embodiments of the present invention, in order to enable the use of resource reaches maximization, optimal situation is exactly so that edge
The resource requirement of user equipment ratio shared in the resource requirement of all user equipmenies and edge band resource are in the base station
It can be that ratio shared in the frequency domain resource of user equipment distribution is identical.Therefore, preset ratio threshold value for example can be set to
Edge band resource ratio shared in the summation of edge band resource and center frequency-band resource, i.e. edge band resource is at this
Base station can be ratio shared in the frequency domain resource of user equipment distribution.Since ICIC includes dynamic I CIC and static state ICIC two
Kind mode, wherein when ICIC is specially static state ICIC mode, preset ratio threshold value can be a fixed value, for example,
40%；Alternatively, when ICIC is specially dynamic I CIC mode, because edge band resource is in the base station when dynamic I CIC mode
It can be dynamic change for ratio shared in the frequency domain resource of user equipment distribution, then preset ratio threshold value is also possible to move
State variation.
In embodiments of the present invention, certainly, in practical applications, ratio shared by general edge band resource all will not be too
Greatly, so needing edge customer equipment too many, it is more nervous otherwise to will cause edge band resource.And it can be optimal
A possibility that situation is very little, it is therefore desirable to so that the resource requirement of edge customer equipment is needed in the resource of all user equipmenies
Shared ratio is closer to preset ratio threshold value in asking, and cannot be greater than preset ratio threshold value.It base station can be from signal matter
It measures minimum user equipment to start, that is, the user equipment to make number one in above-mentioned sequence starts, successively add up selected
User equipment requested resource, to calculate the resource requirement ratio of selected user equipment requested resource.If base
It stands and determines that the resource requirement ratio of M cumulative user equipment is less than or equal to preset ratio threshold value, and determine cumulative M+1
The resource requirement ratio of user equipment is greater than preset ratio threshold value, then base station can then determine this M user equipment for edge use
Family equipment, and determine that the other users equipment in all user equipmenies in addition to this M user equipment is center user equipment.Its
In, M+1 user equipment includes M user equipment and the newly cumulative corresponding user equipment of a resource requirement.
It is to be described in detail by taking cell 0 shown in FIG. 1 as an example further below.Wherein, from low to high according to signal quality
Ranking results are 5 < user equipment of user equipment 6 < user equipment, 4 < user equipment, 3 < user equipment, 2 < user equipmenies 1, and
And the quantity of the resource of the request of 1~user equipment of user equipment 6 is followed successively by 25,10,15,20,15,15, preset ratio threshold value
For example, 40%.Then base station computational resource requirements ratio, money of user equipment 6 since the minimum user equipment 6 of signal quality
Source demand is 15, then the resource requirement ratio acquired for the first time is 15/100, this ratio value is less than 40%.Continue base station
The lower user equipment 6 of selection signal quality and user equipment 5 come computational resource requirements ratio, user equipment 6 and user equipment 5
Resource requirement summation be 25+10=35, then the resource requirement ratio acquired for the second time be 35/100, this ratio value again smaller than
40%.Continue the lower user equipment 6 of selection signal quality, user equipment 5 and user equipment 3 and carry out computational resource requirements ratio in base station
Example, the resource requirement summation of user equipment 6, user equipment 5 and user equipment 3 is 25+10+15=50, then acquires for the third time
Resource requirement ratio is 50/100, this ratio value is greater than 40%, then base station is corresponding by the preceding resource requirement ratio once acquired
User equipment be determined as edge customer equipment, that is, it is true that the corresponding user equipment of resource requirement ratio 35% will be acquired for the second time
It is set to edge customer equipment, here, M equipment refers to the first two user equipment after sorting by signal quality, i.e. user sets
Standby 6, user equipment 5.It is corresponding, base station covering in the other users equipment in addition to edge user equipment then all centered on use
Family equipment.Wherein, can be identical with above-mentioned cumulative mode when being added up, i.e., the resource of a cumulative user equipment needs every time
It asks；In addition, in practical applications, since there are many number of user equipment in base station range, if only increasing by one every time
The resource requirement of user equipment adds up, then need calculate many times, therefore base station can increase when often accumulating once it is more
The resource requirement of a user equipment adds up, such as increased number of user equipment can be 2 or 4 etc., so as to
The time calculated is saved, calculation amount is reduced.
It is to be understood that requesting the quantity of resource herein only for more clearly illustrating the technology of the embodiment of the present invention
Scheme, thus the quantity of the resource of request is simplified, and in practical applications, request resource quantity may not be on
State the quantity enumerated, but it is more increasingly complex than the above-mentioned quantity enumerated more.
In embodiments of the present invention, after determining edge customer equipment, base station then can be these edge customer equipment
Allocations of edge band resource, and be center user equipment distributing center band resource, edge customer equipment is passed through
Edge band resource is communicated with base station and central user equipment can be led to by center frequency-band resource with base station
Letter.For example, the first resource demand percentage that base station determines is 35%, then base station then can be for for being calculated M of 35%
The user equipment allocations of edge resource of frequency range, that is, be the 5 allocations of edge resource of frequency range of user equipment 6 and user equipment, in addition, base
Standing also is the remaining user equipment distributing center resource of frequency range, that is, is 1~user equipment of user equipment, 4 distributing center frequency range
Resource.
In addition, determining that user equipment is edge customer in the embodiment of the present invention after determining the attribute of user equipment
After equipment or central user equipment, in addition to that can give as these edge customer equipment allocations of edge band resources, Yi Jiwei
Except central user equipment distributing center band resource, other scenes, such as the category according to user equipment can also be applied to
Property it is different, cell also has different modes etc. when switching, and the embodiment of the present invention is without limitation.
It is the distribution of edge customer equipment in base station to guarantee that frequency domain resource more fully utilizes in the embodiment of the present invention
After edge band resource, base station also can determine whether edge band resource, and whether there are also remaining.Specifically, being edge customer in base station
After the edge band resource of equipment distribution meets the resource requirement of edge customer equipment, base station then can determine whether edge band resource
Whether there are also residues, if can also give remaining edge band resource allocation to central user equipment there are also remaining.
In conclusion base station can determine a money smaller than preset ratio threshold value according to the resource requirement of user equipment
Source demand percentage, and be determined as being determined as edge customer equipment for the certain customers' equipment for calculating the resource requirement ratio.This
Sample, so that it may make it possible to edge customer equipment ratio shared in all user equipmenies and is in preset proportional region,
And then can control the quantity for capableing of edge customer equipment, it also would not be as in the prior art only according to the geographical position of user equipment
Set be determined user equipment be edge customer equipment or central user equipment, and then occur edge customer equipment excessively
Situation.It is corresponding due to can control the quantity of edge customer equipment meanwhile in the embodiment of the present invention, it can also control
The quantity of central user equipment improves the utilization rate of resource so that center frequency-band resource can also obtain more adequately utilizing.
Also, it is also possible that ratio shared by the ratio and the edge resource of frequency range of edge customer equipment is roughly equal, and makes
