Wherein, the information carried in resource request include but is not limited to the cell ID of GSM cell, service call type, Request multiplex distance etc. between broadband size, GSM cell.Specifically, multiplex distance is to use two of identical frequency between GSM cell GSM cell meets the minimum distance of interference index, i.e. two GSM cells can use the minimum distance of same frequency spectrum simultaneously.Example Such as, if the minimum distance that identical frequency can be used in GSM cell 1 and GSM cell 2 is 10Km (km), GSM cell 1 and GSM 2 multiplex distances of cell are 10Km.

It include but is not limited to connect about the mode for receiving the resource request for requesting shared frequency spectrum that GSM cell is sent Receive the resource request for being used to request shared frequency spectrum that GSM cell is sent in a manner of message, notice etc..

The resource request for being used to request shared frequency spectrum received is sent to SRC by 302:BSC.

Since BSC does not have the distribution power of shared frequency spectrum in the present embodiment, BSC is receiving GSM cell transmission The resource request for requesting shared frequency spectrum after, in order to make the GSM cell for sending resource request be able to use shared frequency spectrum, The resource request that the GSM cell received is sent is sent to the SRC (Single with shared frequency spectrum distribution power by BSC Rescource Controller, pooling of resources controller).Wherein, SRC is pooling of resources controller, for controlling for the SRC Under each BSC distribute shared frequency spectrum.

It is used to request the resource request of shared frequency spectrum to be sent to the mode of SRC for what is received about BSC, the present embodiment is not Make it is specific limit, including but not limited to by the GSM cell received send be used to request the resource request of shared frequency spectrum with The modes such as notice, message are sent to SRC.

303:SRC receives the resource request for being used to request shared frequency spectrum that BSC is sent, and according to resource request according to shared The determination from unappropriated shared frequency spectrum of sequence of the frequency spectrum at a distance from the dedicated frequency spectrum of GSM from the near to the distant meets GSM cell to money The shared frequency spectrum of the requirement of source interference.

It include but is not limited to meet GSM cell to interfere first resource about requirement of the GSM cell to resource interference is met Requirement, Secondary resource interference requirement and information resources interference requirement at least one resource interference requirement.Its In, first resource interference is the interference in GSM cell, and the requirement of Secondary resource interference is GSM cell and the multiplexing in GSM cell Adjacent frequency interference between other GSM cells in distance, the requirement of information resources interference are GSM cell to shared LTE cell Interference.Specifically, due to there is interference between shared frequency spectrum used in GSM cell, when used total in GSM cell When enjoying frequency spectrum and being closer in frequency spectrum, stronger interference will be generated inside GSM cell, causes GSM cell to shared frequency spectrum Service efficiency is lower；And the adjacent frequency interference due to GSM cell and between other GSM cells in the multiplex distance of GSM cell, When sharing frequency spectrum used in two adjacent GSM cells and being closer in frequency spectrum, also will between two adjacent GSM cells Stronger interference is generated, causes two adjacent GSM cells all very low to the service efficiency of shared frequency spectrum；Again due to existing GSM and LTE share frequency spectrum scene under, be likely to work as GSM cell there are LTE cell in each GSM cell coverage area When the frequency spectrum used with shared LTE cell is closer in shared spectrum domain, the two cells will generate interference, same to drop Therefore the low service efficiency of shared frequency spectrum in order to improve the service efficiency of shared frequency spectrum, is using shared frequency for each needs When the GSM cell of spectrum distributes shared frequency spectrum, it is dry using there are resources between each GSM cell for sharing frequency spectrum that needs should be avoided It disturbs.

Further, since each GSM cell has cell ID, and the cell ID of each GSM cell is only One, the longitude on each GSM cell position can be oriented on geographical location by the cell ID of each GSM cell And latitude, to know within the scope of multiplexing belonging to the GSM cell it according to the longitude of each GSM cell position and latitude Spread spectrum scenarios are shared used in his GSM cell and LTE cell, therefore, according to the cell ID of GSM cell for each needs Just can avoid when distributing shared frequency spectrum using the GSM cell of shared frequency spectrum in GSM cell, between GSM cell and with it is shared Interference is generated between LTE cell.Wherein, multiplexing range is centered on GSM cell, and the multiplex distance of the GSM cell is radius Circumference in range.And include in the resource request sent using the GSM cell of shared frequency spectrum to BSC due to each needs Send the cell ID of the GSM cell, therefore, SRC the resource request for requesting shared frequency spectrum for receiving BSC transmission it Afterwards, requirement of the GSM cell to resource interference can be met according to the resource request received is determining from unappropriated shared frequency spectrum Shared frequency spectrum.Again by by each only shared frequency spectrum of the shared frequency spectrum for needing to distribute using the GSM cell of shared frequency spectrum In a part share frequency spectrum, therefore, for the ease of subsequent analysis, method provided in this embodiment is according to the money that receives Source request can incite somebody to action before determination meets the shared frequency spectrum of requirement of the GSM cell to resource interference in unappropriated shared frequency spectrum Shared frequency spectrum is divided into continuously shared frequency spectrum.Specifically, the method for shared frequency spectrum being divided into continuous shared frequency spectrum, including But it is not limited in the following way:

Firstly, determining division mode；

Wherein, it when shared frequency spectrum being divided into continuously shared frequency spectrum, can be used shared frequency spectrum from close to the dedicated frequency of GSM Spectrum side is the division mode that is divided of starting point, also be can be used shared frequency spectrum from being starting point close to the dedicated frequency spectrum side LTE The division mode divided, for the ease of subsequent analysis, using shared frequency spectrum is dedicated from close GSM in the present embodiment It is illustrated for the division mode that frequency spectrum side is divided for starting point.

Secondly, shared frequency spectrum is divided into continuously shared frequency spectrum according to preset step-length according to determining division mode.

Wherein, preset step-length can be 200kHz (kHz), 300kHz, 500kHz etc., and the present embodiment is not to default step Long size makees specific limit.If the spectral range where shared frequency spectrum is 1000kHz~2000kHz, preset step-length size For 200kHz, it is that starting point is divided that the division mode for sharing frequency spectrum, which is from the side close to the dedicated frequency spectrum of GSM, then can will share Frequency spectrum is divided into 1000kHz~1200kHz, 1200kHz~1400kHz, 1400kHz~1600kHz, 1600kHz~1800kHz And the continuous shared frequency spectrum of 1800kHz~2000kHz.After adopting the above method, shared frequency spectrum will be divided into a series of continuous Shared frequency spectrum, obtained shared frequency spectrum is analyzed for the ease of subsequent, in the present embodiment by the shared frequency spectrum of division from It is that starting point is successively sequentially numbered close to the side of the dedicated frequency spectrum of GSM, respectively shared frequency spectrum f1, f2, f3 ..., fn. Wherein, f1 is the shared frequency spectrum near the dedicated frequency spectrum of GSM, and fn is the shared frequency spectrum near the dedicated frequency spectrum of LTE.

After being divided in the manner described above to shared frequency spectrum, due to carrying the cell of GSM cell in resource request Mark, SRC can know the GSM needed using shared frequency spectrum after receiving resource request according to the resource request received Spread spectrum scenarios are shared used in each GSM cell and LTE cell within the scope of multiplexing belonging to cell, and are needed using shared Spread spectrum scenarios are shared used in each GSM cell and shared LTE cell within the scope of multiplexing belonging to the GSM cell of frequency spectrum Difference, therefore, in order to avoid the adjacent frequency interference and GSM cell and shared LTE cell between GSM cell and other GSM cells Interference, SRC according to the resource request received from unappropriated shared frequency spectrum determination meets GSM cell to resource interference It is required that shared frequency spectrum when, can be according to sequence of the shared frequency spectrum at a distance from the dedicated frequency spectrum of GSM from the near to the distant from unappropriated total It enjoys in frequency spectrum and being determined.When it is implemented, sequence of the SRC according to shared frequency spectrum at a distance from the dedicated frequency spectrum of GSM from the near to the distant Determine that the shared frequency spectrum for meeting requirement of the GSM cell to resource interference is also different from unappropriated shared frequency spectrum, therefore, SRC is according to the resource request received according to sequence of the shared frequency spectrum at a distance from the dedicated frequency spectrum of GSM from the near to the distant from unallocated Shared frequency spectrum in determine when meeting shared frequency spectrum of the GSM cell to the requirement of resource interference, it is including but not limited to following several Situation:

The first situation: SRC is determined according to the resource request received sends multiplexing belonging to the GSM cell of resource request Each GSM cell is not all using shared frequency spectrum in range；

For the first situation, sent belonging to the GSM cell of resource request if SRC is determined according to the resource request received Multiplexing within the scope of each GSM cell and shared LTE cell all not using shared frequency spectrum, then no matter SRC is the GSM at this time Which section that cell is distributed in shared frequency spectrum, which shares frequency spectrum, all will not generate interference to adjacent area, but be existed by SRC in this present embodiment When determining the shared frequency spectrum for the requirement for meeting resource interference for the GSM cell according to shared frequency spectrum at a distance from the dedicated frequency spectrum of GSM Sequence from the near to the distant is selected, therefore, at this time will be small as GSM is met near the shared frequency spectrum f1 of the dedicated frequency spectrum of GSM The shared frequency spectrum of requirement of the area to resource interference.

For the above process, in order to make it easy to understand, with a specific example will carry out that explanation is explained in detail below.

As shown in figure 4, at a certain moment, share frequency spectrum since a certain GSM cell of the demand of business needs to use, then the needs Resource request will be sent to BSC using the GSM cell of shared frequency spectrum, BSC the resource request for receiving GSM cell transmission it Afterwards, the resource request that the GSM cell received is sent is sent to SRC, SRC is determined according to the resource request received sends money Each GSM cell within the scope of multiplexing belonging to the GSM cell of source request, then will be near GSM all without using shared frequency spectrum The shared frequency spectrum f1 of dedicated frequency spectrum is determined as meeting the shared frequency spectrum of requirement of the GSM cell to resource interference.

Second situation: SRC is determined according to the resource request received sends multiplexing belonging to the GSM cell of resource request Other GSM cells in range are used for partial sharing frequency spectrum.

For second situation, if other within the scope of the multiplexing according to belonging to the GSM cell for sending resource request of SRC GSM cell is used for partial sharing frequency spectrum, then at this time SRC by according to the shared frequency spectrum that has used according to shared frequency spectrum with The determination from unappropriated shared frequency spectrum of the sequence of the distance of the dedicated frequency spectrum of GSM from the near to the distant meets GSM cell to resource interference Requirement shared frequency spectrum.

Frequency spectrum is shared used in other GSM cells within the scope of the multiplexing as belonging to the GSM cell for sending resource request The case where there are many, in the case of SRC needed by GSM cell using shared frequency spectrum from unappropriated shared frequency spectrum The shared frequency spectrum of the determining requirement for meeting resource interference is different, therefore, in order to make it easy to understand, below for resource is sent The different situations that frequency spectrum is shared used in other GSM cells in multiplex distance belonging to the GSM cell of request will combine Fig. 5 It is introduced respectively to Fig. 7.

As shown in figure 5, being answered belonging to the GSM cell of resource request if SRC determines to send according to the resource request received Frequency spectrum f1 is shared with there is a GSM cell to use in range, and the GSM cell faces with the GSM cell for using shared frequency spectrum is needed Closely, then SRC is determined from unappropriated shared frequency spectrum according to sequence of the shared frequency spectrum at a distance from the dedicated frequency spectrum of GSM from the near to the distant Shared frequency spectrum near the dedicated frequency spectrum of GSM is f2, but due to needing the GSM cell using shared frequency spectrum to use shared frequency spectrum f2 When, adjacent frequency will be generated using the GSM cell of shared frequency spectrum and the GSM cell by, which needing, interferes, and therefore, SRC will continue from unallocated Shared frequency spectrum in select, if SRC is according to sequence of the shared frequency spectrum at a distance from the dedicated frequency spectrum of GSM from the near to the distant from unappropriated When selecting shared frequency spectrum f3 in shared frequency spectrum, and needing using the GSM cell of shared frequency spectrum using shared frequency spectrum f3, meet Therefore shared frequency spectrum f3 can be determined as the GSM cell and wanted to resource interference is met by the requirement that GSM cell interferes adjacent frequency The shared frequency spectrum asked.

As shown in fig. 6, being answered belonging to the GSM cell of resource request if SRC determines to send according to the resource request received With in range with there are two GSM cells on the position of one cell in GSM cell interval is pressed using shared frequency spectrum f1 and f3, SRC It is determined from unappropriated shared frequency spectrum near GSM according to sequence of the shared frequency spectrum at a distance from the dedicated frequency spectrum of GSM from the near to the distant The shared frequency spectrum of dedicated frequency spectrum is f2, since shared frequency spectrum f2 meets requirement of the GSM cell to resource interference, can will be total to Enjoy the shared frequency spectrum that frequency spectrum f2 is determined as the GSM cell to the requirement for meeting resource interference.

As shown in fig. 7, if sending outside multiplexing range belonging to the GSM cell of resource request has a GSM cell to use altogether Frequency spectrum f1 is enjoyed, while SRC is determined according to the resource request received and sent within the scope of multiplexing belonging to the GSM cell of resource request Frequency spectrum f2 and f3 are shared with using on the position of one cell in GSM cell interval there are two GSM cell, SRC is according to shared frequency The sequence at a distance from the dedicated frequency spectrum of GSM from the near to the distant is composed to determine from unappropriated shared frequency spectrum near the dedicated frequency spectrum of GSM Shared frequency spectrum be f1, since shared frequency spectrum f1 meets requirement of the GSM cell to resource interference, although and shared frequency spectrum f1 by It uses, but as using the GSM cell of shared frequency spectrum f1 outside the multiplexing range belonging to the GSM cell, it can be by shared frequency Spectrum f1 is determined as the GSM cell to the shared frequency spectrum for the requirement for meeting resource interference.

304:SRC sends the GSM cell that meets for being used to indicate and determining from unappropriated shared frequency spectrum to BSC and does to resource The instruction information of the shared frequency spectrum for the requirement disturbed.

Due in above-mentioned steps SRC according to resource request according to shared frequency spectrum at a distance from the dedicated frequency spectrum of GSM by close and Remote sequence determines the shared frequency spectrum for meeting requirement of the GSM cell to resource interference from unappropriated shared frequency spectrum, therefore, this SRC will send the instruction information for being used to indicate the shared frequency spectrum for meeting requirement of the GSM cell to resource interference to BSC in step.

What 305:BSC received that SRC returns is used to indicate the finger for meeting the shared frequency spectrum for the requirement that GSM cell interferes adjacent frequency Show information, and will indicate that the shared frequency spectrum indicated in information is determined as unallocated and meets the requirement that GSM cell interferes adjacent frequency Shared frequency spectrum.

Since the SRC shared frequency spectrum determined meets requirement of the GSM cell to resource interference, BSC is receiving SRC What is returned is used to indicate after the instruction information for meeting the shared frequency spectrum for the requirement that GSM cell interferes adjacent frequency, by what is received Indicate that the shared frequency spectrum indicated in information is determined as shared frequency spectrum that is unallocated and meeting requirement of the GSM cell to resource interference, And the instruction information is sent to the GSM cell for sending resource request in subsequent step 306.

306:BSC is used to indicate according to the cell ID for the GSM cell for including in resource request to GSM cell transmission shared The instruction information of frequency spectrum.

It include the cell mark of GSM cell in the resource request sent using the GSM cell of shared frequency spectrum to BSC due to needs Know, and the cell of the GSM cell be it is unique, therefore, BSC meets GSM cell to money receiving being used to indicate for SRC return Source interference requirement shared frequency spectrum instruction information after, BSC can be asked according to resource in include GSM cell cell ID The GSM cell for sending resource request is accurately found in the numerous GSM cells controlled from it, and instruction information will be received and sent Give the GSM cell.

In order to more intuitively show scheduling after share frequency spectrum service condition, be with the cell for using shared frequency spectrum below For LTE cell and GSM cell carry out that explanation is explained in detail.

As shown in figure 8, a certain moment, GSM cell is needed using shared frequency spectrum, which will send resource to BSC and ask It asks, after the resource request that the GSM cell that BSC is received is sent, the resource request that GSM cell is sent is sent to SRC, After SRC receives resource request, request have a LTE within the scope of the multiplexing for determining GSM cell according to the resource-area received Cell is shared shown in spread spectrum scenarios such as Fig. 8 (b) used in the LTE cell using frequency spectrum is shared.In order to avoid GSM cell Resource interference is generated between LTE cell, SRC will avoid sharing frequency spectrum used in LTE cell, from remaining shared frequency spectrum It determines and meets the shared frequency spectrum that GSM cell requires resource interference, and then send the instruction letter for being used to indicate shared frequency spectrum to BSC This is used to indicate the finger of shared frequency spectrum after BSC receives the instruction information for being used to indicate shared frequency spectrum of SRC transmission by breath Show that information is sent to GSM cell.By above-mentioned scheduling process, shared shown in frequency spectrum such as Fig. 8 (a) used in GSM cell.

So far, the scheduling of shared frequency spectrum is realized through the above steps, in this process, when some GSM cell is due to industry The demand of business needs to discharge occupied shared frequency spectrum, and method provided in this embodiment also supports the release of shared frequency spectrum.Specifically Ground can be achieved by the steps of about the release process of shared frequency spectrum:

The first step, the GSM cell for needing to discharge occupied shared frequency spectrum send the release request of shared frequency spectrum to BSC；

Wherein, the release request for sharing frequency spectrum includes but is not limited to the spectrum information of the cell ID of GSM cell, release Deng.

Second step, BSC will receive shared frequency after receiving the release request of the shared frequency spectrum of GSM cell transmission The release request of spectrum is sent to SRC；

Third step, SRC return to shared frequency spectrum release message to BSC, shared frequency spectrum release message are sent to this by BSC GSM cell makes the GSM cell discharge occupied shared frequency spectrum according to the shared frequency spectrum release message received；

4th step, GSM cell send to BSC after discharging occupied shared frequency spectrum and successfully discharge disappearing for shared frequency spectrum Breath, the message that this is successfully discharged to shared frequency spectrum by BSC are sent to SRC.

Further, in order to improve the utilization rate of shared frequency spectrum, SRC receive successfully discharge shared frequency spectrum message it Afterwards, occupied shared Frequency spectrum ratio will be judged whether there is within the scope of the multiplexing belonging to the GSM cell for discharging shared frequency spectrum to release The shared frequency spectrum put is from the farther GSM cell of the dedicated spectral distance of GSM:

1) the step of frequency spectrum that will be discharged is replaced if it does not exist, is not then executed；

2) if it exists, then continue to judge the shared frequency spectrum of occupied shared Frequency spectrum ratio release from the dedicated spectral distance of GSM Whether farther GSM cell supports the replacement of frequency spectrum；

Specifically, when judging, can according to used shared frequency spectrum with a distance from the shared frequency spectrum discharged by remote and Close sequence is judged, if there is the GSM cell for supporting replacement frequency spectrum replacement, will be supported shared by the GSM cell of frequency spectrum replacement Shared frequency spectrum is substituted for the shared frequency spectrum of release.

For the above process, in order to make it easy to understand, carrying out that explanation is explained in detail below in conjunction with Fig. 9.

As shown in figure 9, a certain GSM cell using shared frequency spectrum f1 of a certain moment needs to occupy due to the demand of business Shared frequency spectrum f1 release, which will send the release request of shared frequency spectrum to BSC, and BSC is receiving shared frequency spectrum After release request, the release for receiving shared frequency spectrum request is sent to SRC, SRC is asked in the release for receiving shared frequency spectrum After asking, the release message of shared frequency spectrum is generated, and the release message of shared frequency spectrum is returned into BSC, by BSC by shared frequency spectrum The release message GSM cell, so that the GSM cell is discharged occupied shared frequency spectrum f1.After shared frequency spectrum f1 is released, SRC judges to meet within the scope of the multiplexing belonging to the GSM cell there are two the GSM cells of frequency spectrum replacement condition, the two GSM are small It is respectively f2 and f3 that frequency spectrum is shared used in area, since f3 is opposite and f2 is farther from f1, from using shared frequency spectrum f3's GSM cell starts the replacement for judging whether to support frequency spectrum, if supporting the replacement of frequency spectrum using the GSM cell of shared frequency spectrum f3, F1 is substituted for by f3 by frequency spectrum is shared used in the GSM cell, if not supporting frequency spectrum using the GSM cell of shared frequency spectrum f3 Replacement, then judge whether the GSM cell using shared frequency spectrum f2 supports the replacement of frequency spectrum, if small using the GSM of shared frequency spectrum f2 Area supports the replacement of frequency spectrum, then will share frequency spectrum used in the GSM cell and be substituted for f1 by f2, if using shared frequency spectrum f2's GSM cell does not support the replacement of frequency spectrum, then does not execute the step of frequency spectrum that will be discharged is replaced.

Example IV

The embodiment of the present invention provides a kind of method for dispatching shared frequency spectrum, in order to make it easy to understand, now in conjunction with above-described embodiment One content is illustrated method provided in this embodiment so that BSC dispatches shared frequency spectrum as an example.Referring to Figure 11, this reality Applying the method flow that example provides includes:

1101:BSC receives the resource request for being used to indicate shared frequency spectrum that GSM cell is sent.

1102:BSC, which selects to meet GSM cell from unappropriated shared frequency spectrum according to resource request, wants resource interference The shared frequency spectrum asked, and the shared frequency spectrum selected is determined as unallocated and meets requirement of the GSM cell to resource interference Shared frequency spectrum.

It include but is not limited to meet GSM cell to interfere first resource about requirement of the GSM cell to resource interference is met Requirement, Secondary resource interference requirement and information resources interference requirement at least one resource interference requirement.Its In, first resource interference is the interference in GSM cell, and the requirement of Secondary resource interference is GSM cell and the multiplexing in GSM cell Adjacent frequency interference between other GSM cells in distance, the requirement of information resources interference are GSM cell to shared LTE cell Interference.

In order to make the GSM cell for sending resource request be able to use shared frequency spectrum, BSC is receiving GSM cell transmission After resource request, by according to the resource request received determine GSM cell belonging to each GSM cell within the scope of multiplexing be total to The service condition of frequency spectrum is enjoyed, and then determines the shared frequency spectrum for meeting the requirement of resource interference from unappropriated shared frequency spectrum, and The shared frequency spectrum selected is determined as shared frequency spectrum that is unallocated and meeting requirement of the GSM cell to resource interference.Wherein, will Shared frequency spectrum is divided into shared frequency spectrum in the specific implementation and above-described embodiment two of continuous shared frequency spectrum in step 303 The implementation for being divided into continuous shared frequency spectrum is identical, referring specifically to the content of step 302 in above-described embodiment two, herein not It repeats again.

About being selected to meet requirement of the GSM cell to resource interference from unappropriated shared frequency spectrum according to resource request Shared frequency spectrum, including but not limited to:

Further, since the priority for sharing frequency spectrum is that selection meets GSM to resource from unappropriated shared frequency spectrum The key of interference requirement therefore, can be according to resource request according to shared frequency spectrum in order to make BSC after receiving resource request Priority the shared frequency spectrum for meeting requirement of the GSM cell to resource interference, this implementation are selected from unappropriated shared frequency spectrum The method that example provides is selecting to meet requirement of the GSM cell to resource interference from unappropriated shared frequency spectrum according to resource request Shared frequency spectrum before, will also determine the priority of shared frequency spectrum.About the priority of all shared frequency spectrums of determination, including but not It is limited to determine the priority of shared frequency spectrum at a distance from the dedicated frequency spectrum of GSM according to shared frequency spectrum.Specifically, according to shared frequency spectrum with When the distance of the dedicated frequency spectrum of GSM determines the priority of shared frequency spectrum, including but not limited to the following two kinds situation:

The first situation: according to shared frequency spectrum from the near to the distant by the priority of shared frequency spectrum at a distance from the dedicated frequency spectrum of GSM It is set as from high to low；

For the first situation, if shared frequency spectrum is drawn from the near to the distant at a distance from the dedicated frequency spectrum of GSM according to shared frequency spectrum It is divided into a series of shared frequency spectrum, is respectively as follows: f1, f2, f3.......fn, then shares priority from high to low suitable of frequency spectrum Sequence are as follows: f1, f2, f3.......fn.

Second situation: it will be shared from the near to the distant at a distance from the dedicated frequency spectrum of GSM and the dedicated frequency spectrum of LTE according to shared frequency spectrum The priority level initializing of frequency spectrum is from high to low.

For second situation, if shared frequency spectrum is drawn from the near to the distant at a distance from the dedicated frequency spectrum of GSM according to shared frequency spectrum It is divided into a series of shared frequency spectrum, is respectively as follows: f1, f2, f3.......fn, then shares priority from high to low suitable of frequency spectrum Sequence are as follows: f1, fn, f2, fn-1 ....

In order to avoid resource interference, BSC is selecting to meet GSM cell from unappropriated shared frequency spectrum according to resource request Before the shared frequency spectrum of requirement to resource interference, other base station controllers in multiplexing range belonging to GSM cell will be also received The second shared frequency spectrum that BSC is sent occupies message so that in subsequent step BSC can be occupied according to the second shared frequency spectrum message and The resource request that GSM cell is sent selects to meet GSM from unappropriated shared frequency spectrum according to the priority of all shared frequency spectrums The shared frequency spectrum of requirement of the cell to resource interference.Wherein, multiplexing range belonging to GSM cell is centered on GSM cell, GSM The multiplex distance of cell is the circumference range of radius.Second shared frequency spectrum, which occupies, carries the shared of each BSC distribution in message Occupied information and cell ID of frequency spectrum etc., the content that the present embodiment does not occupy message to the second frequency spectrum make specific limit.

For the above process, in order to make it easy to understand, below by with share frequency spectrum priority according to the dedicated frequency of GSM cell The distance of spectrum carries out that explanation is explained in detail for being set as from the near to the distant from high to low.

For example, if BSC according to the second frequency spectrum for receiving occupy message determine it is each within the scope of multiplexing belonging to GSM cell A GSM cell is all without occupying shared frequency spectrum, then BSC, will be according to shared after the resource request for receiving GSM cell transmission Sequence of the frequency spectrum at a distance from the dedicated frequency spectrum of GSM cell from the near to the distant is selected from unappropriated shared frequency spectrum from the dedicated frequency of GSM The nearest shared frequency spectrum f1 of spectrum, and the shared frequency spectrum f1 selected is determined as unallocated and meets GSM cell to resource interference Requirement shared frequency spectrum；If BSC occupies message according to the second frequency spectrum received and determines within the scope of multiplexing belonging to GSM cell There is a GSM cell to occupy shared frequency spectrum f1, then BSC, will be according to shared after the resource request for receiving GSM cell transmission Sequence of the frequency spectrum at a distance from the dedicated frequency spectrum of GSM cell from the near to the distant is selected from unappropriated shared frequency spectrum from the dedicated frequency of GSM The nearest shared frequency spectrum f2 of spectrum, and the shared frequency spectrum f2 selected is determined as unallocated and meets GSM cell to resource interference Requirement shared frequency spectrum.

Further, if a certain moment BSC receives the resource request of at least two GSM cells transmission simultaneously, due to BSC The resource request of GSM cell transmission can only be handled every time, and therefore, BSC is needed according to each of transmission resource request at this time The cell ID of GSM cell selects a resource request from the resource request that at least two GSM cells are sent, and then according to quilt Select resource request that the GSM cell for meeting the selected resource request of transmission is selected to want resource interference from unappropriated shared frequency spectrum The shared frequency spectrum asked.

It is sent according to the cell ID for each GSM cell for sending resource request from least two GSM cells about BSC The mode of a resource request is selected in resource request, including but not limited to:

Embodiment five

The embodiment of the present invention provides a kind of method for dispatching shared frequency spectrum, in order to make it easy to understand, now in conjunction with above-described embodiment One content is illustrated method provided in this embodiment so that BSC dispatches shared frequency spectrum as an example.Referring to Figure 13, this reality Applying the method flow that example provides includes:

1301:BSC receives the resource request for being used to request shared frequency spectrum that GSM cell is sent.

1302:BSC is selected unallocated and is met GSM cell to money according to resource request from corresponding shared subset of spectrum The shared frequency spectrum of the requirement of source interference.

In order to avoid the resource interference between GSM cell, method provided in this embodiment also by by the way of spectrum reuse, Shared frequency spectrum is divided into multiple shared subset of spectrum by the spectrum reuse factor, and is drawn shared frequency spectrum according to shared subset of spectrum number It is divided into shared subset of spectrum several shared frequency spectrums again, and then the shared frequency spectrum after division is assigned to each shared subset of spectrum In.Wherein, it shares subset of spectrum to be divided according to the corresponding relationship with GSM cell, each shared subset of spectrum and each GSM Cell corresponds, and the shared subset of spectrum number divided is identical as multiplexing factor number.Wherein, shared frequency spectrum is divided into continuously Shared frequency spectrum specific implementation and above-described embodiment two in shared frequency spectrum is divided into continuous shared frequency in step 303 The implementation of spectrum is identical, and referring specifically to the content of step 302 in above-described embodiment two, details are not described herein again.

Further, it in order to guarantee to generate resource interference between GSM cell, is assigned to respectively by the shared frequency spectrum after dividing When in a shared subset of spectrum, need to guarantee that the shared frequency spectrum in each shared subset of spectrum will not generate resource interference.In order to Guarantee that the shared frequency spectrum in each shared subset of spectrum will not generate resource interference, is assigned to respectively by the shared frequency spectrum after dividing When in a shared subset of spectrum, the dedicated shared frequency spectrum composed again and again of distance GSM can be successively divided into each shared subset of spectrum In.For example, shared subset of spectrum number is 3, it is respectively as follows: A1, A2, A3, the shared spectrum number of division is 9, respectively f1, F2 ... f1 can then be assigned in A1, f2 is assigned in A2, f3 is assigned in A3, then f4 is assigned to A1 by .f9 In ... ..., until f9 is assigned in A3, shared subset of spectrum each at this time are as follows: A1 { f1, f4, f7 }, A2 f2, f5, F8 }, A3 { f3, f6, f9 }.

For example, the multiplex mode that Figure 14 is 3 × 3.Wherein, 3 × 3 multi-meters are shown with 3 base stations, and each base station has 3 small Area.By the way of 3 × 3 multiplexings, same frequency spectrum is multiplexed after being spaced two cells.Due to the number of subsets and multiplexing factor of division Number is identical, therefore, shared frequency spectrum can be divided into 9 shared subset of spectrum according to 3 × 3 multiplex mode.If shared frequency spectrum divides Shared spectrum number be 27, that is, the shared frequency spectrum divided be f1, f2 ... .f27, then by after division shared frequency spectrum distribute It include each 3 shared frequency spectrums in shared subset of spectrum when into each shared subset of spectrum.Specifically, if by shared frequency spectrum Subset indicates that the shared subset of spectrum then comprising the shared frequency spectrum after dividing can with A1, A2, A3, B1, B2, B3, C1, C2 and C3 To be expressed as A1 { f1, f10, f19 }, A2 { f2, f11,20 }, A3 { f3, f12, f21 }, B1 { f4, f13, f22 }, B2 f5, f14, F23 }, B3 { f6, f15, f24 }；C1 { f7, f16, f15 }, C2 { f8, f17, f26 }, C3 { f9, f18,27 }.

Since each shared subset of spectrum and each GSM cell correspond, and each sharing in subset of spectrum has correspondence Pre-assigned shared frequency spectrum, and the shared frequency spectrum in each shared subset of spectrum will not generate resource interference each other, Therefore, BSC can be selected from corresponding shared subset of spectrum after receiving according to resource request according to the resource request received Unappropriated shared frequency spectrum.Specifically, it is selected from corresponding shared subset of spectrum according to the resource request received unallocated Shared frequency spectrum, including but not limited to:

According to resource request according in corresponding shared subset of spectrum share frequency spectrum priority from shared subset of spectrum It selects unallocated and meets the shared frequency spectrum that GSM cell requires resource interference.

According to resource request according in corresponding shared subset of spectrum share frequency spectrum priority from shared subset of spectrum Before selecting shared frequency spectrum that is unallocated and meeting requirement of the GSM cell to resource interference, further includes:

Wherein, each shared frequency in subset of spectrum is shared about according to shared frequency spectrum is determining at a distance from the dedicated frequency spectrum of GSM The mode of the priority of spectrum, including but not limited to the following two kinds situation:

For the first situation, BSC is asked after the resource request for receiving GSM cell transmission according to the resource received Ask preferentially selected from corresponding subset it is unappropriated and from the closer shared frequency spectrum of the dedicated spectral distance of GSM, and by selection Frequency spectrum is shared as the shared frequency spectrum for meeting requirement of the GSM cell to resource interference.

For the above process, in order to make it easy to understand, below carrying out that explanation is explained in detail still by taking Figure 13 as an example.

Shared subset of spectrum is A1 { f1, f10, f19 }, A2 { f2, f11,20 }, A3 { f3, f12, f21 }, B1 f4, f13, F22 }, B2 { f5, f14, f23 }, B3 { f6, f15, f24 }；C1 { f7, f16, f15 }, C2 { f8, f17, f26 }, C3 f9, f18, 27}.When a certain moment BSC receives the resource request that the corresponding GSM cell of shared subset A1 is sent, if unappropriated total in A1 Enjoying frequency spectrum is f1, f10 and f19, then can be using the shared frequency spectrum f1 nearest from the dedicated frequency spectrum of GSM as meeting GSM cell to resource The shared frequency spectrum of the requirement of interference；It, can will be nearest from the dedicated frequency spectrum of GSM if unappropriated shared frequency spectrum is f10 and f19 in A1 Shared frequency spectrum f10 as the shared frequency spectrum for meeting requirement of the GSM cell to resource interference；If unappropriated shared frequency spectrum in A1 It, then can be using the shared frequency spectrum f19 nearest from the dedicated frequency spectrum of GSM as meeting being total to for requirement of the GSM cell to resource interference for f19 Enjoy frequency spectrum.

For second situation, BSC is asked after the resource request for receiving GSM cell transmission according to the resource received It asks and preferentially selects unallocated and nearest from the dedicated frequency spectrum of GSM and the dedicated frequency spectrum of LTE shared frequency spectrum from corresponding subset, and will The shared frequency spectrum selected is as the shared frequency spectrum for meeting requirement of the GSM cell to resource interference.

For the above process, in order to make it easy to understand, below carrying out that explanation is explained in detail still by taking Figure 14 as an example.

Shared subset of spectrum is A1 { f1, f10, f19 }, A2 { f2, f11,20 }, A3 { f3, f12, f21 }, B1 f4, f13, F22 }, B2 { f5, f14, f23 }, B3 { f6, f15, f24 }；C1 { f7, f16, f15 }, C2 { f8, f17, f26 }, C3 f9, f18, 27}.When a certain moment BSC receives the resource request that the corresponding GSM cell of shared subset A1 is sent, if unappropriated total in A1 Enjoying frequency spectrum is f1, f10 and f19, then can be using the shared frequency spectrum f1 nearest from the dedicated frequency spectrum of GSM as meeting GSM cell to resource The shared frequency spectrum of the requirement of interference, can also be using the shared frequency spectrum f19 nearest from the dedicated frequency spectrum of LTE as meeting GSM cell to money The shared frequency spectrum of the requirement of source interference；It, can will be from the dedicated frequency spectrum of LTE most if unappropriated shared frequency spectrum is f10 and f19 in A1 Close shared frequency spectrum f19 is as the shared frequency spectrum for meeting requirement of the GSM cell to resource interference.
