Specific embodiment

Frequency spectrum of embodiment of the present invention distributing equipment is determined according to the distance between target BS and each adjacent base station Usable spectrum of each adjacent base station relative to the target BS, and according to the available frequency of each adjacent base station Spectrum, determines predistribution frequency spectrum of each adjacent base station relative to the target BS, is each phase according to predistribution frequency spectrum Adjacent base station carries out frequency spectrum distribution, carries out frequency spectrum distribution for multi-operator frequency spectrum share scene to realize;It further increases System performance.And the embodiment of the present invention uses centralized management mode, carries out between the base station for belonging to different operators Efficient frequency spectrum distribution, the frequency spectrum distributed is shared resource, compared to the mode of existing operator's separate spectrum licence plate, energy More efficient promotion frequency spectrum service efficiency is conducive to meet the needs of following 5G is for spectral efficient and high-speed.

In an implementation, the frequency spectrum distributing equipment of the embodiment of the present invention can be the advanced spectrum management list in centralized architecture Member is perhaps central manage-ment unit or is called database facility, which, which has, is connected to (example on operator's existing equipment Such as Network Management Equipment) function.

The embodiment of the present invention is described in further detail with reference to the accompanying drawings of the specification.

As shown in Figure 1A, the system that the embodiment of the present invention one distributes frequency spectrum includes: frequency spectrum distributing equipment 10 and base station 20.

Frequency spectrum distributing equipment 10, for determining each need of the target BS and the target BS that have carried out frequency spectrum distribution Carry out the distance between the adjacent base station of frequency spectrum distribution;According to the distance between target BS and each adjacent base station, Determine usable spectrum of each adjacent base station relative to the target BS, and according to the available of each adjacent base station Frequency spectrum determines predistribution frequency spectrum of each adjacent base station relative to the target BS;For an adjacent base station, If the target BS of only one in the adjacent base station of the adjacent base station, by the adjacent base station relative to the target base The predistribution frequency spectrum stood distributes to the adjacent base station;If there is multiple target bases in the adjacent base station of the adjacent base station It stands, the predistribution frequency spectrum according to the adjacent base station relative to each target BS carries out frequency spectrum for the adjacent base station Distribution.

Base station 20, for determining that frequency spectrum distributing equipment is the frequency spectrum of base station distribution;In the frequency spectrum distributing equipment point It is transmitted on the frequency spectrum matched.

Wherein, each adjacent base station and target BS of the embodiment of the present invention can belong to different operators.

Frequency spectrum distributing equipment can obtain each operator's site location information at the initial stage of building a station by preconfigured mode, Or the geographical location information of administrative base station is reported by operator during operation.

Frequency spectrum allocation result can be sent to by frequency spectrum distributing equipment when distributing frequency spectrum for adjacent base station with signaling message Each base station of operator.

Target BS of the embodiment of the present invention is the base station for having carried out frequency spectrum distribution, for a target BS, determines the mesh The adjacent base station for needing to carry out frequency spectrum distribution in base station around mark base station, then determines each adjacent base station relative to institute State the predistribution frequency spectrum of target BS.

For adjacent base station, it is possible to around have multiple target BS, can determine that this is adjacent for each base station Predistribution frequency spectrum of the base station relative to target BS.

If only one predistribution frequency spectrum relative to target BS is only needed pre- point relative to target BS The adjacent base station is distributed to frequency spectrum;

If there is multiple predistribution frequency spectrums relative to target BS, by the adjacent base station relative to each target The intersection frequency spectrum of the predistribution frequency spectrum of base station distributes to the adjacent base station.

For example having target BS A and target BS B around adjacent base station 1, then frequency spectrum distributing equipment can determine whether adjacent base station 1 Relative to the predistribution frequency spectrum A of target BS A, and determine predistribution frequency spectrum B of the adjacent base station 1 relative to target BS B, so The intersection frequency spectrum for pre-allocating frequency spectrum A and predistribution frequency spectrum B is distributed into the adjacent base station 1 afterwards.

When determining predistribution frequency spectrum of the adjacent base station relative to target BS due to frequency spectrum distributing equipment, for each target The mode for the predistribution frequency spectrum that base station determines is all identical, so be no longer introduced respectively for different target BS, below It is introduced just for some target BS.

The frequency spectrum distributing equipment of the embodiment of the present invention receives the spectrum requirement information of operator base station, and determines multi-operator Base station between relationship;Each base station reports the information such as self geographical position and spectrum bandwidth requirements, itself RF capabilities.Frequency spectrum Distributing equipment is counted and is analyzed whole base station locations (including having disposed base station and having proposed the base station of spectrum requirement), divides each base The type stood.

Specifically, frequency spectrum distributing equipment determines each according to the distance between target BS and each adjacent base station When usable spectrum of the adjacent base station relative to the target BS, for an adjacent base station, the frequency spectrum distribution Equipment according to distance range and for indicate with the corresponding relationship of the type of target BS distance, determine target BS and the phase The corresponding type of range belonging to the distance between adjacent base station, and using determining type as the type of the adjacent base station;

The frequency spectrum distributing equipment determines each adjacent base station relative to described according to the type of each adjacent base station The usable spectrum of target BS.

Frequency spectrum of embodiment of the present invention distributing equipment preset condition according to needed for dividing base station classification, determines each adjacent base The type stood.

Wherein, preset condition is distance range, and specific distance range can be set according to emulation, experience etc..Such as it can To set first distance and second distance, base station type can be divided into three kinds in this way:

It indicates the remote first kind (referring to Figure 1B) of distance between target BS: meeting distance between website and be more than or equal to the Two base stations of one distance, it is believed that be typically much deeper than the sum of two website covering radius, identical work at this moment can be used Frequency, the power density interfered with each other between base station is approximately equal to noise at this time.

Indicate the farther away Second Type of distance (referring to Fig. 1 C) between target BS: distance is less than first between meeting website Distance and two base stations for being more than or equal to second distance, i.e. always slightly greater than the sum of two website covering radius, it is believed that make It is worked near by frequency, is leaked in another base station operation frequency band from a Base Transmitter signal at this time, form interference, it should The power density of interference is approximately equal to noise.

Indicate the close third type (referring to Fig. 1 D) of distance between target BS: meet between website distance less than second away from From two base stations, i.e., be usually less than equal to the sum of two website covering radius, it is believed that worked using frequency farther out so that Leakage jamming power density between base station is approximately equal to noise.

For first kind base station, it is believed that it is spaced far between adjacent base station and target BS, it is non-overlapping mutually, it is believed that meet With frequency coverage condition, so all frequency spectrums are available;

For Second Type base station, it is believed that the geographical location between adjacent base station and target BS is adjacent, according to each other Isolated instances are managed, when meeting certain frequency isolation, adjacent frequency coexistence is carried out, then counts each Second Type base station and target BS Geographic isolation distance, then determine each Second Type base station minimal geographical isolation distance (the multiple target BS in periphery with The distance of the Second Type base station is different, and selects the smallest distance, then corresponds to the isolation of maximum frequency spectrum) in the case of it is corresponding Frequency isolation degree, then the frequency spectrum for meeting frequency spectrum isolation is usable spectrum.It should be noted that because the second class of periphery Type base station may include macro station and small station, although macro station and the geographic isolation that ought be set out in advance to make arrangements are farther out, the transmission power of macro station is big, because This may also need biggish frequency spectrum to be isolated.So to distinguish macro station and small station to periphery station to handle.

For third type of base station base station, it is believed that adjacent base station and target BS are located at partly overlapping region, then frequency spectrum The adjacent area interference measurement that distributing equipment receives third type of base station reports, and counts total disturbed condition on each frequency spectrum, then It selects to interfere lesser frequency spectrum as usable spectrum always for third type of base station.Each frequency spectrum can be equal to third type of base station Radio frequency bandwidth ability.

Based on above content, the frequency spectrum distributing equipment determines each described adjacent according to the type of each adjacent base station Usable spectrum of the base station relative to the target BS, specific:

If one, the type of the adjacent base station is the first kind that distance is remote between expression and target BS, for one The adjacent base station of the first kind, the frequency spectrum distributing equipment is using all usable spectrums as the adjacent base station relative to the mesh Mark the usable spectrum of base station.

That is, for the first kind adjacent base station can consider it is spaced far between adjacent base station and target BS, mutually It is mutually non-overlapping, it is believed that meet with frequency coverage condition.

If two, the type of the adjacent base station is to indicate the farther away Second Type of distance between target BS, for one The adjacent base station of a Second Type, the frequency spectrum distributing equipment determine the adjacent base station and adjacent each specific objective base station The distance between, and determine the corresponding frequency isolation degree of the shortest distance, the frequency spectrum of determining frequency isolation degree will be met as institute Usable spectrum of the adjacent base station relative to the target BS is stated, wherein the specific objective base station is and the adjacent base station phase The type of the adjacent base station can be made as the target BS of Second Type in the adjacent target BS.

That is, the adjacent base station for Second Type can consider the geographical location between adjacent base station and target BS It is adjacent, adjacent frequency coexistence is carried out when meeting certain frequency isolation according to mutual geographic isolation situation.

Such as have target BS A, target BS B and target BS C around adjacent base station 1, wherein according to target BS B and The distance between adjacent base station 1 can determine that the type of adjacent base station 1 is Second Type, according to target BS C and adjacent base station 1 The distance between can determine adjacent base station 1 type be Second Type, then target BS B and target BS C be exactly relative to The specific objective base station of adjacent base station 1.

When determining the shortest distance, from the distance between target BS B and adjacent base station 1 and target BS C and adjacent In the distance between base station 1.Select the shortest distance.

When determining that the corresponding frequency isolation of the shortest distance is spent, can previously according to emulation or experience set distance range and Then the corresponding relationship of frequency isolation degree determines belonging to the shortest distance according to the corresponding relationship of distance range and frequency isolation degree The corresponding frequency isolation degree of distance range.

Preferably, the transmission power due to macro station is greater than small station, for identical distance, macro station with it is adjacent Interference between base station can be bigger, so required frequency isolation degree is also greater than small station.Based on this, in set distance range and When the corresponding relationship of frequency isolation degree, it can be directed to the site type of different target base station, set respectively.

Frequency spectrum distributing equipment first judges that adjacent base station is macro station or small station, described if the adjacent base station is macro base station Frequency spectrum distributing equipment determines distance belonging to the shortest distance according to the distance range of macro base station and the corresponding relationship of frequency isolation degree The corresponding frequency isolation degree of range;If the adjacent base station is small station, the frequency spectrum distributing equipment is according to the distance range in small station With the corresponding relationship of frequency isolation degree, the corresponding frequency isolation degree of distance range belonging to the shortest distance is determined.

If three, the type of the adjacent base station is the third type that distance is close between expression and target BS, for one The adjacent base station of third type, the frequency spectrum distributing equipment determines total interference of the adjacent base station on each frequency spectrum, and selects Select the usable spectrum for interfering the smallest frequency spectrum as the adjacent base station relative to the target BS.

It partly overlaps that is, the adjacent base station for being directed to third type can consider that adjacent base station and target BS are located at Region, contain here approximate with covering and neighbouring covering.

In an implementation, it can be set as needed the width of each frequency spectrum, i.e., entire frequency spectrum be divided into multiple frequency spectrum benchmark Unit, split-phase adjacent base station distribute frequency spectrum reference cell.The size of frequency spectrum reference cell can be according to the radio frequency bandwidth of adjacent base station Ability setting.For example the frequency spectrum reference cell can be equal to the radio frequency bandwidth ability of adjacent base station.

In an implementation, when frequency spectrum distributing equipment carries out frequency spectrum distribution to the base station of each operator, its three classes base can be integrated The usable spectrum stood.It may include in result for the base station distribution frequency spectrum of each operator identical or neighbouring as other operators Frequency spectrum.

Specifically, primarily meeting base station classification institute when distributing frequency spectrum for each of each operator base station to be allocated Corresponding usable spectrum range, wherein the usable spectrum range of all kinds of base stations is the first kind > Second Type > third type.

Based on this, when being allocated, frequency spectrum resource C first is distributed for third type all to be allocated;It is again the second class Type distributes frequency spectrum resource (B-C).Frequency spectrum resource (A-B) finally is distributed for first kind base station, specifically may refer to Fig. 1 E.Specifically :

The frequency spectrum distributing equipment determines each adjacent base station phase according to the usable spectrum of each adjacent base station For the predistribution frequency spectrum of the target BS, comprising:

The frequency spectrum distributing equipment is according to the demand bandwidth and each third type of the adjacent base station of each third type Usable spectrum of the adjacent base station relative to the target BS, determine the adjacent base station of each third type relative to the mesh Mark the predistribution frequency spectrum of base station;

Usable spectrum of the frequency spectrum distributing equipment from the adjacent base station of each Second Type relative to the target BS In, predistribution frequency spectrum of the adjacent base station of third type relative to the target BS is removed, according to second each of after removal The adjacent base station of type is relative to the usable spectrum of the target BS and the demand band of the adjacent base station of each Second Type Width determines predistribution frequency spectrum of the adjacent base station relative to the target BS of each Second Type;

The frequency spectrum distributing equipment removes the adjacent base station of third type relative to the target from all usable spectrums The predistribution frequency spectrum of the predistribution frequency spectrum of base station and the adjacent base station of Second Type relative to the target BS, according to removal The demand bandwidth of the adjacent base station of usable spectrum and each first kind afterwards, determines the adjacent base station phase of each first kind For the predistribution frequency spectrum of the target BS.

The adjacent area interference measurement results that above specific method of salary distribution is reported according to each base station, in usable spectrum resource with The bandwidth demand that base station reports is unit, counts interference strength on the frequency spectrum of constituent parts length, and base station selected have to be each The usable spectrum for meeting bandwidth demand of least interference intensity.

If be unable to satisfy, frequency spectrum distributing equipment reduces the bandwidth that base station reports demand, such as base station radio-frequency ability can With support { B1, B2, B3 }, and B1 > B2 > B3, this reports demand B1 to be unable to satisfy, and frequency spectrum distributing equipment will be the base according to B2 It stands and selects idle frequency spectrum again, when the bandwidth that final all RF capabilities are supported all is unable to satisfy, then refuse asking for base station It asks.

The scheme of the embodiment of the present invention is illustrated by taking Fig. 1 F as an example below.

For reporting the operator base station of demand, the set of three classes base station: first kind base station, Second Type has been marked off Base station, third type of base station.If macro cell (macrocell) website home-operator 1, small cell (cell) website Home-operator 2.It is reference with marco cell website, and the spacing for setting macro cell website and small cell a meets More than or equal to first distance, the spacing of macro cell website and small cell b, which meet, to be less than first distance and is greater than etc. In second distance, the spacing of macro cell website and small cell c, which meet, is less than second distance.

So at this point it is possible to obtained base station category division result are as follows: when being reference with marco cell website, Small cell a is first kind base station, and small cell b is Second Type base station, and small cell c is third type Base station.

The spectrum bandwidth requirements that each website reports are set again are as follows: marco cell website is Ma Hz, and small cell a is Sa Hz, small cell b are Sb Hz, and small cell c is Sc Hz.And total available bandwidth resources B Hz meets above-mentioned each website Bandwidth demand.

In total available bandwidth B, adjacent area interference measurement is carried out by type 2 site small cell c, in available resources In B Hz as unit of Sc Hz, interference strength on the frequency spectrum of constituent parts bandwidth length is counted, selects that there is least interference intensity Bandwidth Sc Hz, and using this bandwidth as frequency spectrum resource C, distribute to small cell c.

Adjacent area interference measurement is carried out by type 2 site small cell b again, removes Sc in available resources B Hz On frequency spectrum except Hz, using (Sb-Sc) Hz as unit, interference strength on the frequency spectrum of constituent parts bandwidth length is counted, selection has Bandwidth (Sb-Sc) Hz of least interference intensity is distributed using this bandwidth as frequency spectrum resource (B-C) together with frequency spectrum resource C together Give B class website small cell b.
