Multiple operators, owing to user is at zones of different, skewness on the time, causes the load accessing network of different operators in the time, spatially there are differences, thus the demand of frequency spectrum be there are differences. Static spectrum allocation strategy makes the access network of different operators can not adjust the frequency spectrum resource taken dynamically according to the change of offered load, can not be fully utilized and frequency spectrum supersaturation utilization thus causing frequency spectrum resource.

In the prior art, not yet not for the scheme of multi-operator frequency spectrum share. And for the multisystem (many RAT (RadioAccessType in such as operator, wireless access type)) between frequency spectrum share, and the frequency spectrum share of cognitive radio system and other main system, it is substantially based on access data base or physical layer frequency spectrum perception technology, realize idle frequency spectrum resource between system sharing use, it is impossible to meet multi-operator frequency spectrum share.

Detailed description of the invention

Embodiment of the present invention frequency spectrum distributing equipment is according to the distance between target BS and each described adjacent base station, determine each described adjacent base station usable spectrum relative to described target BS, and the usable spectrum according to each described adjacent base station, determine each described adjacent base station predistribution frequency spectrum relative to described target BS, it is that each adjacent base station carries out frequency spectrum distribution according to predistribution frequency spectrum, it is achieved thereby that carry out frequency spectrum distribution for multi-operator frequency spectrum share scene; Further increase systematic function. And the embodiment of the present invention adopts centralized management mode, efficient frequency spectrum distribution is carried out between the base station of different operators belonging to, the frequency spectrum distributed is for sharing resource, mode compared to existing operator separate spectrum licence plate, the more efficient lifting frequency spectrum service efficiency of energy, is conducive to meeting the following 5G demand for spectral efficient and two-forty.

In force, the frequency spectrum distributing equipment of the embodiment of the present invention can be the advanced spectrum management unit in centralized architecture, or being central manage-ment unit, or be called database facility, this equipment possesses and is connected on operator's existing equipment the function of (such as Network Management Equipment).

Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.

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

Frequency spectrum distributing equipment 10, for determining each distance needing to carry out between the adjacent base station of frequency spectrum distribution of the target BS carrying out frequency spectrum distribution and described target BS; According to the distance between target BS and each described adjacent base station, determine each described adjacent base station usable spectrum relative to described target BS, and the usable spectrum according to each described adjacent base station, it is determined that each described adjacent base station is relative to the predistribution frequency spectrum of described target BS; For a described adjacent base station, if target BS described in only one of which in the adjacent base station of described adjacent base station, described adjacent base station is distributed to described adjacent base station relative to the predistribution frequency spectrum of described target BS; If the adjacent base station of described adjacent base station has multiple described target BS, according to the described adjacent base station predistribution frequency spectrum relative to each described target BS, carry out frequency spectrum distribution for described adjacent base station.

Base station 20, for determining the frequency spectrum that frequency spectrum distributing equipment is the distribution of described base station; The frequency spectrum of described frequency spectrum distributing equipment distribution is transmitted.

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

The mode that frequency spectrum distributing equipment can pass through to be pre-configured with at the initial stage of building a station obtains each operator site location information, or is reported the geographical location information of administrative base station during runing by operator.

Frequency spectrum distributing equipment is when distributing frequency spectrum for adjacent base station, it is possible to signaling message, frequency spectrum allocation result is sent to each base station of operator.

Embodiment of the present invention target BS is the base station having carried out frequency spectrum distribution, for a target BS, determine the adjacent base station needing to carry out frequency spectrum distribution in the base station around this target BS, it is then determined that each described adjacent base station is relative to the predistribution frequency spectrum of described target BS.

For adjacent base station, it is possible to around have multiple target BS, this adjacent base station predistribution frequency spectrum relative to target BS can be determined for each base station.

If only one of which is relative to the predistribution frequency spectrum of target BS, then have only to the predistribution frequency spectrum relative to target BS is distributed to described adjacent base station;

If there being multiple predistribution frequency spectrum relative to target BS, described adjacent base station is distributed to described adjacent base station relative to the common factor frequency spectrum of the predistribution frequency spectrum of each described target BS.

Target BS A and target BS B is had around such as adjacent base station 1, then frequency spectrum distributing equipment can determine whether the adjacent base station 1 predistribution frequency spectrum A relative to target BS A, and determine the adjacent base station 1 predistribution frequency spectrum B relative to target BS B, then the common factor frequency spectrum of predistribution frequency spectrum A and predistribution frequency spectrum B is distributed to described adjacent base station 1.

When determining adjacent base station relative to the predistribution frequency spectrum of target BS due to frequency spectrum distributing equipment, the mode of the predistribution frequency spectrum determined for each target BS is identical, so being no longer introduced respectively for different target BS, it is introduced just for some target BS below.

The frequency spectrum distributing equipment of the embodiment of the present invention receives the spectrum requirement information of operator base station, and determines relation between the base station of multi-operator; Each base station reports self geographical position and the information such as spectrum bandwidth requirements, self RF capabilities. Whole base station location (including disposing base station and proposing the base station of spectrum requirement) is added up and analyzed to frequency spectrum distributing equipment, divides the type of each base station.

Concrete, frequency spectrum distributing equipment is according to the distance between target BS and each described adjacent base station, when determining each described adjacent base station relative to the usable spectrum of described target BS, for a described adjacent base station, described frequency spectrum distributing equipment is according to distance range with for representing the corresponding relation of the type with target BS distance, determine the type that the scope belonging to the distance between target BS with described adjacent base station is corresponding, and using type as described adjacent base station of the type determined;

Embodiment of the present invention frequency spectrum distributing equipment is pre-conditioned according to what divide needed for base station classification, it is determined that the type of each adjacent base station.

Wherein, pre-conditioned is distance range, and concrete distance range can set according to emulation, experience etc. Such as can set that the first distance and second distance, so base station type can be divided into three kinds:

Represent the first kind (referring to Figure 1B) remote with the spacing of target BS: meet site distance from two base stations be more than or equal to the first distance, it is believed that be typically much deeper than two website covering radius sums, at this moment can using identical operating frequency, now the power density interfered between base station approximates noise.

Represent Second Type (referring to Fig. 1 C) distant between target BS: meet site distance from less than the first distance and two base stations be more than or equal to second distance, namely always slightly greater than two website covering radius sums, it is believed that use near by frequency work, now it is leaked in another base station operation frequency band from a Base Transmitter signal, forming interference, the power density of this interference approximates noise.

Represent threeth type (referring to Fig. 1 D) near with the spacing of target BS: meet site distance from two base stations less than second distance, namely it is typically smaller than equal to two website covering radius sums, it is believed that use frequency work farther out so that the leakage jamming power density between base station approximates noise.

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

For Second Type base station, think that the geographical position between adjacent base station and target BS is adjacent, according to mutual geographical isolation situation, when meeting certain frequency isolation, carry out adjacent frequency coexistence, then add up the geographical isolation distance of each Second Type base station and target BS, it is then determined that each Second Type base station is at minimal geographical isolation distance, (the multiple target BS of periphery is different from the distance of this Second Type base station, select minimum distance, then corresponding maximum frequency spectrum isolation) frequency isolation degree corresponding in situation, the frequency spectrum so meeting frequency spectrum isolation is usable spectrum. it should be noted that because periphery Second Type base station potentially includes macro station and small station, although macro station with when the geographical isolation set out in advance to make arrangements farther out, but the transmitting power of macro station is big, is therefore likely to and needs bigger frequency spectrum isolation. so, macro station is distinguished at periphery station and small station processes.

For the 3rd type of base station base station, think that adjacent base station and target BS are positioned at partly overlapping region, then the adjacent area interferometry of frequency spectrum distributing equipment reception the 3rd type of base station reports, the statistics total disturbed condition on each frequency spectrum, is then that the 3rd type of base station selects always to disturb less frequency spectrum as usable spectrum. Each frequency spectrum can be equal to the radio frequency bandwidth ability of the 3rd type of base station.

Based on foregoing, the described frequency spectrum distributing equipment type according to each adjacent base station, it is determined that each described adjacent base station is relative to the usable spectrum of described target BS, concrete:

If the type of a described adjacent base station is the first kind that expression is remote with the spacing of target BS, for the adjacent base station of a first kind, described frequency spectrum distributing equipment using all usable spectrums as the described adjacent base station usable spectrum relative to described target BS.

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

Two, if the type of described adjacent base station is Second Type distant between expression and target BS, adjacent base station for a Second Type, described frequency spectrum distributing equipment determines the distance between described adjacent base station and adjacent each specific objective base station, and determine the frequency isolation degree that beeline is corresponding, the frequency spectrum of frequency isolation degree determined will be met as the described adjacent base station usable spectrum relative to described target BS, wherein said specific objective base station is the type target BS as Second Type that can make described adjacent base station in the described target BS adjacent with described adjacent base station.

It is to say, for the adjacent base station of Second Type it is believed that the geographical position between adjacent base station and target BS is adjacent, according to mutual geographical isolation situation, when meeting certain frequency isolation, carry out adjacent frequency coexistence.

Target BS A, target BS B and target BS C is had around such as adjacent base station 1, wherein may determine that the type of adjacent base station 1 is Second Type according to the distance between target BS B and adjacent base station 1, may determine that according to the distance between target BS C and adjacent base station 1 type of adjacent base station 1 is Second Type, then target BS B and target BS C is exactly the specific objective base station relative to adjacent base station 1.

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

When determining that frequency isolation corresponding to beeline is spent, previously according to emulation or the corresponding relation of experience set distance range and frequency isolation degree, then can determine, according to distance range, the frequency isolation degree that the distance range belonging to beeline is corresponding with the corresponding relation of frequency isolation degree.

It is preferred that owing to the transmitting power of macro station is greater than small station, therefore for identical distance, the interference between macro station and adjacent base station can be relatively larger, so required frequency isolation degree is also greater than small station. Based on this, when the corresponding relation of set distance range and frequency isolation degree, it is possible to for the site type of different target base station, be set respectively.

Frequency spectrum distributing equipment first judges that adjacent base station is macro station or small station, if described adjacent base station is macro base station, the corresponding relation of the described frequency spectrum distributing equipment distance range according to macro base station and frequency isolation degree, it is determined that the frequency isolation degree that distance range belonging to beeline is corresponding; If described adjacent base station is small station, the corresponding relation of the described frequency spectrum distributing equipment distance range according to small station and frequency isolation degree, it is determined that the frequency isolation degree that distance range belonging to beeline is corresponding.

If the type of three described adjacent base stations is the 3rd type that expression is near with the spacing of target BS, adjacent base station for the 3rd type, described frequency spectrum distributing equipment determines the total interference on each frequency spectrum of the described adjacent base station, and selects the minimum frequency spectrum of interference as the described adjacent base station usable spectrum relative to described target BS.

It is to say, for the adjacent base station of the 3rd type it is believed that adjacent base station and target BS are positioned at partly overlapping region, contain approximate with covering and contiguous covering here.

In force, it is possible to set the width of each frequency spectrum as required, it is divided into multiple frequency spectrum reference cell by whole frequency spectrum, point adjacent base station distribution frequency spectrum reference cell. The size of frequency spectrum reference cell can set according to the radio frequency bandwidth ability of adjacent base station. Such as described frequency spectrum reference cell can be equal to the radio frequency bandwidth ability of adjacent base station.

In force, when the base station of each operator is carried out frequency spectrum distribution by frequency spectrum distributing equipment, it is possible to the comprehensively usable spectrum of its three classes base station. For the result of the base station distribution frequency spectrum of each operator can comprise identical with other operator or contiguous frequency spectrum.

Concrete, when distributing frequency spectrum for the base station each to be allocated in each operator, primarily meet the usable spectrum scope corresponding to the classification of base station, wherein the usable spectrum scope of all kinds of base stations is the first kind > Second Type > the 3rd type.

Based on this, when being allocated, it is first the 3rd type distribution frequency spectrum resource C all to be allocated; Frequency spectrum resource (B-C) is distributed again for Second Type. Finally distribute frequency spectrum resource (A-B) for first kind base station, specifically may refer to Fig. 1 E. Concrete:

The described frequency spectrum distributing equipment usable spectrum according to each described adjacent base station, it is determined that each described adjacent base station relative to the predistribution frequency spectrum of described target BS, including:

The adjacent area interference measurement results that the above concrete method of salary distribution reports according to each base station, on available spectrum resources in units of the bandwidth demand that base station reports, interference strength on the frequency spectrum of statistics constituent parts length, and be each base station selected usable spectrum meeting bandwidth demand with least interference intensity.

If cannot meet, then frequency spectrum distributing equipment reduction base station reports the bandwidth of demand, such as base station radio-frequency ability can support { B1, B2, B3}, and B1 > B2 > B3, this reports demand B1 to meet, frequency spectrum distributing equipment will select idle frequency spectrum according to B2 for this base station again, when the bandwidth that final all RF capabilities are supported all cannot meet, then refuse the request of base station.

For Fig. 1 F, the scheme of the embodiment of the present invention is illustrated below.

For reporting the operator base station of demand, mark off the set of three class base stations: first kind base station, Second Type base station, the 3rd type of base station. If macrocell (macrocell) website home-operator 1, smallcell (small-cell) website home-operator 2. With marcocell website for reference, and it is satisfied with the first distance with the spacing of smallcella to set macrocell website, macrocell website and the spacing of smallcellb meet satisfied with less than the first distance and the spacing be more than or equal to second distance, macrocell website and smallcellc second distance.

So at this point it is possible to the base station category division result obtained is: when with marcocell website for reference, smallcella is first kind base station, and smallcellb is Second Type base station, and smallcellc is the 3rd type of base station.

Set again spectrum bandwidth requirements that each website reports as: marcocell website is MaHz, smallcella be SaHz, smallcellb be SbHz, smallcellc is ScHz. And always available bandwidth resources BHz meets above-mentioned each website bandwidth demand.

In total available bandwidth B, adjacent area interferometry is carried out by Second Type website smallcellc, in available resources BHz in units of ScHz, interference strength on the frequency spectrum of statistics constituent parts bandwidth length, select the bandwidth ScHz with least interference intensity, and using this bandwidth as frequency spectrum resource C, distribute to smallcellc.

Adjacent area interferometry is carried out again by Second Type website smallcellb, remove on the frequency spectrum outside ScHz in available resources BHz, with (Sb-Sc) Hz for unit, interference strength on the frequency spectrum of statistics constituent parts bandwidth length, select bandwidth (Sb-Sc) Hz with least interference intensity, using this bandwidth as frequency spectrum resource (B-C), together distribute to B class website smallcellb together with frequency spectrum resource C.

Finally, owing to can work with frequency between first kind website, therefore remove on remainder (B-Sb) Hz outside frequency spectrum resource (B-C) and frequency spectrum resource C in available bandwidth, do not need to measure, arbitrarily bandwidth is selected to be (Sa-Sb) Hz for smallcella, as frequency spectrum resource (A-B), together distribute to A class website smallcella together with frequency spectrum resource (B-C) and frequency spectrum resource C.

Through above-mentioned distribution, it is achieved that the optimum use of frequency spectrum resource, i.e. at utmost Reusespectrum resource between each smallcell website, the interference between each website can be avoided by identical networking in same operator simultaneously. It addition, coexisting between another operator website macrocell can also be met.
