Third embodiment of the invention provides a kind of sharing method of frequency spectrum resource, in the present embodiment, the reality of this method Now exist with frequency spectrum share form server, the frequency spectrum share server by utilizing tidal effect, occupied according to region frequency spectrum uneven The situation of weighing apparatus, GSM are dynamically distributed by own spectrum utilization power and release frequency spectrum resource are used to LTE, it will be able to save frequency Spectrum resource improves the availability of frequency spectrum.The frequency spectrum share server according to GSM and LTE respectively the regionality of frequency spectrum characteristic and business, Temporal correlation, dynamic divides and adjustment shared region, realizes and partial frequency spectrum resource is shared between GSM and LTE, effectively carry The high availability of frequency spectrum.

The frequency spectrum share server of the present embodiment relates generally to the region division of the frequency spectrum scheduling of GSM and LTE and shares Frequency spectrum distribution and scheduling in area, GSM is because of main carry voice traffic, the main bearing data services of LTE, this system frequency spectrum share Principle is recycled, GSM and LTE respectively distributes certain static resource;Remaining is preferential to main carrying voice as dynamic spectrum resource The GSM of business is used, and during the GSM frequency spectrum resource free time, shares to LTE use.Frequency spectrum share process needs BSC, frequency spectrum share service Device, eNB cooperation complete, system group network figure as shown in figure 5, including:

1st, initial configuration management module:Frequency spectrum share server is operated in, major function has:Believe with the interface of BSC, eNB Breath management, obtains GSM, LTE and other initial configuration informations.

2nd, shared region division module (function of being equivalent to the sharing means of the frequency spectrum resource in second embodiment):It operates in Frequency spectrum share server, according to the GSM cell availability of frequency spectrum, the interference for the cell that transfinites to the GSM availability of frequency spectrums and (be more than thresholding 1) Adjacent area is analyzed, and divides shared region, and periodically (Timer 1) carries out shared region adjustment.

3rd, Message forwarding module (effect of messaging):Frequency spectrum share server is operated in, pair between GSM/LTE Transparent transmission message is forwarded.

5th, shared region bandwidth adjustment module (function module interacted with frequency spectrum share server):Operation and eNB, management The shared region and bandwidth allocation of LTE cells.

Above system networking diagram each section workflow is as shown in fig. 6, in figure 6, the present embodiment services frequency spectrum share The dynamic spectrum resource allocation function that device is realized has been arranged on BSC sides, it can be seen that, which can be real inside BSC It is existing, frequency spectrum share server can also be sent data to, to be realized in frequency spectrum share server.The process of system operation is such as Under, including the first step to the 4th step:

The first step:The interference adjacent area of each cell is planned and is configured in BSC, in frequency spectrum share server, configuring spectrum is shared Range and the stage.

Open frequency spectrum share function after, frequency spectrum share server is interacted with BSC and eNB, so as to frequency spectrum share server from GSM and radio configuration data needed for two side draws of LTE.

Second step:BSC is after configuration data has been reported, periodic statistics and the spectrum utilization situation for reporting each cell.Frequently Spectrum shared server according to thresholding 1 (availability of frequency spectrum transfinite thresholding) screening high load capacity cell, then pass through each cell interference it is adjacent The shared region of area, analysis and output GSM and LTE.

Third walks:Frequency spectrum share server issues shared region information to GSM and LTE.In each shared region, according to The stage is initially shared in the frequency spectrum resource demand analysis of GSM, and periodically (Timer1) analyzes GSM frequency spectrum resource demands, adjustment later The shared stage.Dynamic frequency point is distributed higher than 1 cell of thresholding, less than (spectrum utilization the crosses low threshold) cell of thresholding 2 release dynamics frequency Point.If encountering accident, GSM frequency spectrum resource demands promptly rise and (are more than thresholding 3), can share the stage with emergency adjustment.

4th step:BSC periodically (Timer2) reports spectrum utilization situation to frequency spectrum share server, frequency spectrum share service Device periodicity analysis and shared region is planned again.Wherein, Timer1>Timer2, Timer1 generally as unit of hour, Timer2 is generally as unit of minute.

In above process, interacting message schematic diagram can be with as shown in fig. 7, wherein present disappearing for each stage progress Breath interaction.

The operation in above-mentioned steps is described in detail below.

The dividing mode of shared region is specific as follows in above-mentioned second step:

Shared region is judged with systematic parameter cycle T imer1, it is assumed that total GSM cell number is C={ C1,C2, ...Cn, wherein, m cell reports within the T periods to transfinite cell for frequency spectrum interest rate:Ch={ Ch1,Ch2,...Chm, transfinite cell i(1<=i<=m) GSM and LTE interference adjacent area be respectively h and l.The GSM interference adjacent area of cell Ci is Gi, Gi={ Gi1, Gi2...Gih}。

Taking frequency spectrum interest rate transfinites cell ChCorresponding GSM interferes adjacent area Gh, judge whether intersection, there are drawing for intersection Enter same shared region, i.e., first setting shared region S1=Gh1IfThen update shared region S1=Gh1∪ Ghi.And so on, shared region S1 is obtained in cycle, then takes S1With ChAnti- collection, is continued to seek shared region S2, be recycled with this until transfiniting Cell is all until distribution.

The selection of GSM frequency points and distribution and residing shared stage confirm that process is specific as follows in above-mentioned third step:

For reasonable distribution frequency point resource, the multistage can be divided to be shared according to actual spectrum situation, such as Step1, Step2 ... Stepn shares, and priority is successively from high to low.

Shared region initially issue after the initially shared stage, the cell that need to be transfinited according to each shared region frequency spectrum enables dynamic frequency Points are calculated.Rudimentary algorithm is:It is transfinited just by the availability of frequency spectrum, successively increases frequency point quantity.Assuming that CiThe frequency of cell Spectrum utilization rate is Load_Ci, then

Load_Cplus=Max { Load_Ch1, Load_Ch2,...Load_Chm, CplusIncrease by 1 dynamic carrier frequency.

Dynamic frequency point basis for selecting interferes minimum principle, that is, calculates each dynamic frequency point and CplusCell and Qi Ge interference adjacent area Interference value, it is target frequency point to take interference value minimum.The interference value of frequency point i, for some interference adjacent area Cj, interference value packet It is interfered containing same frequency and upper and lower adjacent frequency:

Interference value total frequency point i:

For example the stage is shared at certain, l frequency point is shared, then dynamic frequency point least interference value fmin=min { f(1),f(2) ....f(l), if fmin<Interference-tolerant thresholding, then choose fminCorresponding frequency point adds in CplusCell.

Again the availability of frequency spectrum after adding in dynamic frequency point is estimated, is recycled to whole cell spectrum utilization rates less than thresholding Value.When each cell spectrum utilization rate less than thresholding or reaches greatest physical carrier frequency number, then frequency spectrum distribution terminates.If distribution frequency During point, this stage GSM transfinites region fmin>During=interference-tolerant thresholding, startup next stage shares frequency point.With final frequency spectrum point At the end of matching, the shared stage residing for GSM, to originate the shared stage.

For using the network of frequency-hopping system, dynamic MA List can be used, Frequency Hopping Processing Gain are kept, for example, original MAList { T1, T2 } after dynamic frequency point T3 is issued, extends MAList { T1, T2, T3 }, enables corresponding carrier frequency, quote frequency hop sequences.It is next After stage dynamic frequency point T4 is issued, continue to extend MA List { f1, f2, f3, f4 }, enable corresponding carrier frequency, vice versa.

By taking certain network as an example, the frequency spectrum resource of 18MHz 1800M can plan the proprietary frequency points of 3M GSM and the proprietary bands of 3M LTE Width can use shared range 12MHz.LTE bandwidth is with " 3M-5M-10M-15M " 3 ladder extension/releases;GSM bandwidth is with " 5M- 3M, 5M-10M, 10M-15M " points of 3 ladder release/extensions.The GSM frequency spectrums in certain period one of shared region, starting stage Resource utilization is higher, occupies whole dynamic resources, is used as load reduction gradually discharges partial dynamic frequency spectrum resource for LTE. Fig. 8 is the frequency spectrum distribution schematic diagram of some network.

The embodiment of the present invention distributes frequency spectrum resource by regional dynamics, effectively improves the availability of frequency spectrum;The frequency point and occupancy of GSM And the bandwidth of LTE increases or decreases mode using ladder, ensures the continuity of business during shared occur, effectively avoid GSM with Interference between LTE.

Although for example purpose, the preferred embodiment of the present invention is had been disclosed for, those skilled in the art will recognize Various improvement, increase and substitution are also possible, and therefore, the scope of the present invention should be not limited to the above embodiments.
