The upper line frequency selection scheduling efficiency of big data packet service-user, and uplink interference is reduced, it realizes and is reducing uplink interference
Meanwhile while improving the upper line frequency selection scheduling efficiency of all users.
Further, in order to reduce influence of the upper line frequency selection scheduling to big data packet service-user, current base is being detected
Reserved scheduling corresponding with uplink big data packet business can be arranged there are when big data packet service-user in station in upstream bandwidth
RB sections, RB sections of the reserved scheduling is RB sections used in big data packet service-user, i.e., other UE for entering frequency selection scheduling cannot
It is enough to use reserved RB sections of scheduling.Below to how to confirmly detect current base station there are uplink big data packet business and how really
Determine to be specifically introduced in upstream bandwidth with reserved scheduling RB sections corresponding to uplink big data packet business.
Wherein, in the step of detecting current base station there are uplink big data packet business, following a variety of sides can be passed through
Formula determines current base station, and there are uplink big data packet business:
First, being greater than first every in the collected uplink data volume to be dispatched of preset duration institute in statistics predetermined period
The data amount check of the uplink of preset threshold data volume to be dispatched, and work as and detect that the data amount check is greater than uplink in predetermined period
Wait dispatch data volume total times of collection and the first preset ratio threshold value product when, determining current base station, there are uplink big datas
Packet business.
Specifically, the predetermined period can be 1s, total times of collection can be 20 times, every time lasting 50ms, at this time can be with
One of them time point data volume to be dispatched to uplink in 50ms lasting every time counts, this time every it is default when
Length is similarly 50ms.
In addition, specifically, it should be noted that the first preset threshold and the first preset ratio threshold value can bases
Actual demand is set, and is not limited specifically first preset threshold and the first preset ratio threshold value herein.Below
Above situation is illustrated in citing.
For example, carrying out one acquisition at interval of 50ms data volume to be dispatched to uplink in 1s, i.e., total times of collection is 20 times,
Collect 20 uplink data volumes to be dispatched.It is assumed that being shared on A in institute's collected 20 uplinks data volume to be dispatched
Row data volume to be dispatched is greater than the first preset threshold, and the product of total times of collection and the first preset ratio threshold value is B, if at this time
A is greater than B, it is determined that there are uplink big data packet business for current base station.
In this way, that is, collected is more than preset threshold since uplink data volume to be dispatched is capable of the size of response data packet
Uplink data volume to be dispatched number it is more, illustrate that data packet is bigger, be enable to by being acquired in predetermined period
To the data amount check greater than the uplink data volume to be dispatched of the first preset threshold come determine current base station with the presence or absence of uplink it is big
Data packet traffic ensure that the accuracy of the identified result with the presence or absence of uplink big data packet business.
Second, when the uplink scheduling total degree for detecting UE in predetermined period is greater than the total number of sub frames of uplink and the second default ratio
When the product of example threshold value, determining current base station, there are uplink big data packet business.
Specifically, predetermined period can be 1s.The total number of sub frames of uplink is the total number of sub frames of uplink in predetermined period.
In addition, specifically, it should be noted that the second preset ratio threshold value can be set according to actual needs
It is fixed, do not limit the specific value of the second preset ratio threshold value specifically herein.
In this way, the uplink scheduling total degree due to UE in predetermined period is capable of the size of response data packet, i.e. data packet is got over
Greatly, required uplink scheduling total degree is more, is enable to through the uplink total activation number of UE in predetermined period come really
Current base station is determined with the presence or absence of uplink big data packet business, ensure that the identified knot with the presence or absence of uplink big data packet business
The accuracy of fruit.
Third, when the flow value for detecting uplink radio link control (abbreviation RLC) layer is greater than the second preset threshold, really
Determining current base station, there are uplink big data packet business.
Specifically, it should be noted that the second preset threshold can be set according to actual needs, herein not
The specific specific value for limiting the second preset threshold.
In this way, the flow value due to rlc layer is capable of the size of response data packet, i.e. flow value is bigger, illustrates that data packet is got over
Greatly, it is enable to determine that current base station with the presence or absence of uplink big data packet business, ensure that by the flow value of rlc layer
The accuracy of the identified result with the presence or absence of uplink big data packet business.
In this way, the present embodiment passes through the uplink data volume to be dispatched greater than the first preset threshold of acquisition in predetermined period
The flow value of the uplink scheduling total degree of UE or uplink rlc layer in data amount check, predetermined period, whether to determine current base station
There are uplink big data packet business, ensure that the accuracy of the identified result with the presence or absence of uplink big data packet business.
Furthermore, wherein in determining upstream bandwidth and reserved scheduling RB sections corresponding to the uplink big data packet business
When, available current base station is dry every the uplink of RB each in the preset time period that preset duration is counted in predetermined period
Disturb noise figure；Then it according to the uplink interference noise figure of each RB, obtains uplink interference noise figure and is less than the default threshold of third
The target RB of value；Then when there are successive objective RB, and the number of successive objective RB is greater than four preset thresholds, by the company
Continuous target RB is determined as described RB sections of reserved scheduling.
Specifically, predetermined period can be 1s, the preset duration being spaced can be 40ms, and preset time period can be
10ms radio frames, i.e. current base station can sample 20 times in predetermined period 1s, at interval of every in 40ms statistics 10ms radio frames
The uplink interference noise figure of a RB.At this point it is possible to detect whether that there are the uplink interference noise figures of RB to be less than third predetermined threshold value,
The uplink interference noise figure of RB is less than third predetermined threshold value if it exists, it is determined that obtains interference noise value and is lower than third predetermined threshold value
Target RB.In this way, after determining target RB, if detecting the presence of successive objective RB, and the number of successive objective RB is greater than
4th preset threshold, then by successive objective RB be determined as with reserved scheduling RB sections corresponding to uplink big data packet business.
In addition, specifically, it should be noted that preset duration and preset time period can carry out according to the actual situation
Setting does not limit the specific value of preset duration and preset time period specifically herein, and third predetermined threshold value and the 4th is preset
The setting of threshold value can equally be set according to the actual situation, do not limited third predetermined threshold value and the 4th specifically herein and preset
The specific value of threshold value.
In this way, by RB that uplink interference noise figure is less than to third predetermined threshold value as target RB, and will be greater than the
The successive objective RB of the number of four preset thresholds is determined as reserved RB sections of scheduling, so that each of reserved RB sections of scheduling RB is equal
Meet uplink interference noise requirements, and the length of reserved RB sections of scheduling can satisfy uplink big data packet business demand, ensure that
Reserved scheduling RB sections of availability corresponding to identified and uplink big data packet business, to ensure that uplink big data packet
The dispatching efficiency of business.
In addition, specifically, in determining upstream bandwidth with reserved scheduling RB section corresponding to uplink big data packet business
It afterwards, can be by the RB sections of progress uplink schedulings of reserved scheduling, to guarantee that uplink is big if UE corresponds to uplink big data packet business
The dispatching efficiency of data packet user.Certainly, it if UE is not corresponding uplink big data packet business, needs through the reserved scheduling RB
Other RB except section carry out uplink scheduling transmission, to avoid the influence to uplink big data packet service-user.
In addition, further, according to required distribution RB number, at least one continuously available frequency is obtained from upstream bandwidth
Before selecting RB sections, the upper of distribution needed for UE can also be determined according to the Physical Cell Identifier (abbreviation PCI) of serving cell where UE
The initial position row RB, wherein the upstream frequency starting distribution position of the cell with different PCI is different.
In this way, determining the initial position uplink RB distributed needed for UE, and have by the PCI according to serving cell where UE
There is the upstream frequency initial position of the cell of different PCI different, i.e. the upstream frequency initial position of the cell with different PCI is wrong
It opens, makes it possible to reduce the co-channel interference between user, and make it possible to be different small since the initial position uplink RB being staggered
Area user distributes RB, the probability that distributed RB is continuous RB is increased, to increase uplink scheduling efficiency.
Specifically, the PCI of serving cell can when determining the uplink initial position RB distributed needed for UE where according to UE
To include the following steps:
The first step is determined and is calculated according to the default corresponding relationship between three value of mould and upstream bandwidth number of segment of PCI
The PCI three value of mould corresponding to target upstream bandwidth number of segment, wherein upstream bandwidth is divided into three sections in advance.
Specifically, since mould three (abbreviation MOD3) value that the range of PCI is 0 to 503, PCI includes 3 different numbers
Value.At this point it is possible to which the number of the first different numerical value according to included by three value of mould of PCI, divides upstream bandwidth, i.e., in advance
Upstream bandwidth is divided into three sections in advance, then establishes the default correspondence between three sections of upstream bandwidths and three value of mould of different PCI
Relationship.For example, can establish the corresponding relationship between three value 0 of mould of PCI and first segment upstream bandwidth 00, the mould three of PCI is established
Corresponding relationship between value 1 and second segment upstream bandwidth 01 is established between three value 2 of mould of PCI and third section upstream bandwidth 03
Corresponding relationship.In this way, by pre-establishing the default corresponding relationship between three value of mould of PCI and upstream bandwidth number of segment, so that
UE is calculated in three value of mould of the PCI of serving cell, corresponding relationship can be preset according to this, determine used needed for UE it is upper
Row bandwidth number of segment.
For example, it is assumed that the PCI of serving cell where UE is 502, then three value of mould of PCI is 1, at this time can be according to PCI's
Corresponding relationship between three value 1 of mould and second segment upstream bandwidth 01 determines target corresponding to three value of mould for the PCI being calculated
Upstream bandwidth number of segment is second segment upstream bandwidth 01, that is, determines that the target upstream bandwidth number of segment distributed needed for UE is second segment uplink
Bandwidth 01.
In addition, specifically, three sections of upstream bandwidths distinguish included RB number when being divided into three sections in advance to upstream bandwidth
Between difference be less than preset value, which can be set according to demand, but should be ensured that three sections of upstream bandwidths difference
The balance of included RB number, so that each section of upstream bandwidth can guarantee uplink scheduling demand.
Second step obtains the whole value after being rounded to the quotient of the PCI and 3, and described in the whole value is determined as
Bias of the initial position uplink RB relative to the initial position of target upstream bandwidth section, wherein the target upstream bandwidth section is
With bandwidth segments corresponding to the target upstream bandwidth number of segment.
Specifically, in this step it needs to be determined that the initial position uplink RB distributed needed for UE is in identified target uplink
Specific location in bandwidth segments.
Specifically, the quotient of PCI and 3 can be calculated, then the quotient is rounded, and obtains the whole value after being rounded,
The whole value can be determined as to start bit of the initial position uplink RB of distribution needed for UE relative to target upstream bandwidth section at this time
The bias set.In this way, opposite by the initial position uplink RB distributed needed for determining target upstream bandwidth number of segment and UE
Bias in the initial position of target upstream bandwidth section can accurately determine that the initial position uplink RB distributed needed for UE exists
Specific location in upstream bandwidth.
Third step calculates RB number and institute included by all upstream bandwidth sections before being located at the target upstream bandwidth section
State bias and value, and the position RB corresponding to described and value is determined as to the uplink RB of UE required distribution in upstream bandwidth
Initial position.
Specifically, the initial position uplink RB of the distribution needed for determining target upstream bandwidth section and UE is relative to target uplink
After the bias of the initial position of bandwidth segments, all upstream bandwidths before target upstream bandwidth section can be directly calculated
RB number included by section and bias and value, and will be corresponding with value the position RB be determined as UE in upstream bandwidth needed for divide
The initial position uplink RB matched.
For example, it is assumed that the PCI of serving cell where UE is 97, RB number included by first segment upstream bandwidth 00 is 33,
RB number included by second segment upstream bandwidth 01 is 34, and RB number included by third section upstream bandwidth 02 is 33, is calculated
It is 32 that quotient that three value of mould to PCI is 1, PCI and 3, which carries out the value after value, at this time can be according to three value 1 of mould of PCI and the
Corresponding relationship between two sections of upstream bandwidths 01 determines that target upstream bandwidth number of segment corresponding to three value of mould of PCI is second segment
Upstream bandwidth 01, and the initial position uplink RB is 32, i.e. uplink relative to the bias of the initial position of target upstream bandwidth section
The initial position RB is the 32nd position RB on second segment upstream bandwidth 01.At this point, before due to second segment upstream bandwidth 01
First segment upstream bandwidth 00 includes 33 RB, therefore the uplink RB starting of UE required distribution in upstream bandwidth can be calculated
Position is the 55th position RB in entire upstream bandwidth.
In this way, the initial position uplink RB distributed needed for UE is obtained by calculation, so that when carrying out RB distribution, Neng Gouzhi
Connect and be allocated since the initial position uplink RB being calculated, so as to avoid when uplink RB distribution in sequence from the
One RB starts the process distributed backward, thereby reduces inter-user interference, and it is excessively discrete to avoid uplink RB resource allocation,
The problem of influencing uplink scheduling efficiency, while reducing inter-user interference, improve uplink scheduling efficiency.
In addition, further, according to required distribution RB number, at least one continuously available frequency is obtained from upstream bandwidth
, can be long as window using the required distribution RB number when selecting RB sections, after the initial position uplink RB of distribution needed for the UE
All positions RB carry out sliding window search, obtain at least one continuously available frequency and select RB sections；Wherein, when sliding window searches a window
When long included RB is all satisfied the uplink interference noise requirements of the UE, the long included RB of the window is recorded as frequency and selects RB
Section.
Specifically, after determining the initial position uplink RB of distribution needed for UE, can according to the required distribution RB number of UE,
Sliding window search directly is carried out to all positions RB after the initial position uplink RB, if the long included equal energy of RB of a window at this time
Enough meet the uplink interference noise requirements of UE, then the long included RB of window is recorded as frequency and selects RB sections, originated with this in uplink RB
Search obtains at least one and selects RB sections frequently in all positions RB after position.
In this way, passing through the sliding window search at least one from all positions RB after the initial position uplink RB of distribution needed for UE
A continuously available frequency selects RB sections, rather than directly searches for backward since first RB in sequence, between reducing user
While co-channel interference, the probability that the continuously available frequency searched selects RB sections is improved, uplink RB resource allocation is avoided
It is excessively discrete, the problem of influencing uplink scheduling efficiency, improve uplink scheduling efficiency.
In this way, the embodiment of the present invention obtains the required distribution RB number of UE first, and there are uplinks detecting current base station
When big data packet business, determine in upstream bandwidth and reserved scheduling RB sections corresponding to uplink big data packet business, then basis
Required distribution RB number obtains at least one continuously available frequency from upstream bandwidth and selects RB sections, finally continuously may be used from least one
Frequency selects in RB sections, chooses and selects RB sections apart from farthest target frequency with RB section of reserved scheduling, and selected frequently by target RB sections into
Line frequency selection scheduling on row is realized in current base station there are when uplink big data packet business, UE can by with uplink big data
The target frequency of the corresponding reserved RB sections of lie farthest aways of scheduling of packet business selects RB sections to carry out line frequency selection scheduling, enables UE maximum
Limit avoids reserved RB sections of scheduling, by RB sections of progress uplink schedulings of target, so that improving the same of UE dispatching efficiency
When, the influence to big data business user rate can be reduced to greatest extent, to ensure that big data packet service-user
Upper line frequency selection scheduling efficiency, and uplink interference is reduced, it realizes while reducing uplink interference, while it is useful to improve institute
The upper line frequency selection scheduling efficiency at family.
In addition, as shown in Fig. 2, being a kind of module frame chart of upper line frequency selection scheduling device in the embodiment of the present invention, the dress
It sets and includes:
First determining module 201 is worked as obtaining the required distribution resource block RB number of user equipment (UE), and that ought detect
There are when uplink big data packet business, determine in upstream bandwidth to reserve with corresponding to the uplink big data packet business for preceding base station
RB sections of scheduling；
First obtains module 202, continuous for according to required distribution RB number, obtaining at least one from the upstream bandwidth
Available frequency selects RB sections, wherein the frequency select RB sections included by RB number be it is described needed for distribute RB number；
Second obtains module 203, for selecting in RB sections from least one described continuously available frequency, chooses and reserves with described
