Description

The control method and the device of licence sign indicating number during high speed downlink packet inserts

Technical field

The present invention relates to high speed downlink packet and insert (HSDPA) technology, relate in particular to the control method and the device of licence among the HSDPA (License) sign indicating number.

Background technology

HSDPA is that of introducing of third generation communication partner tissue (3GPP) R5 release protocol has breakthrough technology, be on satisfying/the asymmetric demand of downstream data traffic and a kind of new technology of proposing.The HSDPA technology can be under the situation that does not change the WCDMA network configuration of having built, the highest 14Mbps that brings up to of downstream data traffic speed, therefore it is an important technology that the WCDMA networking later stage improves downlink capacity and data service rate, is the enhancing and the evolution of WCDMA at wireless portion.

HSDPA has increased by three new channels on original physical channel: high speed down sharing physical channel (HS-PDSCH), High-Speed Shared Control Channel (HS-SCCH) and High-Speed Dedicated Physical Control Channel (HS-DPCCH).Wherein, the HS-PDSCH channel is used to carry the business datum of HSDPA descending transmission channel, its spreading factor is fixed as 16, adopt four to advance phase-shift keying (QPSK) or 16 quadrature amplitude modulation (QAM) modulation system, each sub-district is configurable 15 HS-PDSCH at most, and the channel code of HS-PDSCH must be continuously; The HS-SCCH channel is used to carry the required control information of downlink data on the demodulation HS-PDSCH channel, and the spreading factor of this channel is fixed as 128, adopts the QPSK modulation system; HS-DPCCH is used to carry the uplink feedback information relevant with descending HS-PDSCH, comprises affirmation (ACK)/non-affirmation (NACK) and channel quality indication information such as (CQI), and the spreading factor of HS-DPCCH channel is fixed as 256.

In the application of reality, the equipment that each communication apparatus production firm provides is supported the ability difference of HSDPA, and each operator is also different about the processing capability requirements of HSDPA to equipment.With regard to operator, the demand difference in each stage to capacity of equipment is promptly at the networking initial stage, little to the demand of the disposal ability of equipment; And As time goes on, because the client is on the increase, business demand is also increasing, and is at this moment also increasing to the processing capability requirements of equipment.For the cost of investment at the initial stage of reducing, operator normally comes the part of purchase of equipment ability according to initial business demand when purchase of equipment, buy other parts according to real needs more later on.Like this, in order to clearly define the disposal ability scope of the equipment that operator buys, the disposal ability that device fabrication manufacturer adopts License to come control appliance to provide is so that to carrier charge.

In the License that device fabrication manufacturer is issued, include the HS-PDSCH number of codewords that the base station can legally have.The angle of (NodeB) from the base station, the HS-PDSCH code word that is had is many more, and the ability of base station interface transmission aloft data is strong more.Usually the HS-PDSCH code word that is comprised among the License is called the License sign indicating number.According to 3GPP TS 25.433 agreements regulation, in a sub-district, all users share the License sign indicating number of distributing to the sub-district, place.Because the License number of codewords among the License is at whole base station.So just need control, it is distributed to each sub-district in this base station a limited number of License sign indicating number that the base station had.

The method of existing control License code word is: the network network planning is based on the License sign indicating number among service in base station model and the License, License sign indicating number for each cell allocation fixed number of this base station. this method is commonly called the static control method of License code word among the HSDPA. use the static control method of this kind, the number of the License sign indicating number of each sub-district is fixed, the professional ability that is had also is also to be limited. under the situation that the HSDPA business demand in the sub-district increases, if the License number of codewords of being distributed can't satisfy the demand of this sub-district, and when operator did not buy more License sign indicating numbers, the business of this sub-district will can't be carried out owing to lacking the License sign indicating number; Do not exist in the sub-district under HSDPA user's the situation, the License sign indicating number in this sub-district has remaining again. and as seen, the shortcoming of existing License code word control method is: the utilance of base station License sign indicating number is lower.

Embodiment

For making purpose of the present invention, technical scheme clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.

Basic thought of the present invention is: base station remaining License code word number is distributed to the sub-district that needs to increase License code word number in this base station.

Base station among the present invention comprises:

Fig. 1 shows the flow chart of the control method of License sign indicating number of the present invention.As shown in Figure 1, the control method of license sign indicating number of the present invention may further comprise the steps:

The License code word that all sub-districts take in License code word number that step 101. has according to the base station and the base station is counted summation, determines base station remaining License code word number.

Step 102. is distributed to the sub-district that needs to increase License code word number in this base station with base station remaining License code word number.

Below by three specific embodiments, the solution of the present invention is elaborated.Below alleged code word be the License code word; And following alleged sub-district is the sub-district of supporting HSDPA.

Embodiment 1

The core concept of present embodiment is and will does not exist the License code assignment of HSDPA user's sub-district to give the sub-district that has HSDPA user and can increase the code word number.Fig. 2 shows the flow chart of the control method of License sign indicating number in the embodiment of the invention 1; Fig. 3 and Fig. 4 are the method flow diagram that distributes the remaining License sign indicating number in base station in the embodiment of the invention 1.

Referring to Fig. 2, the control method of License sign indicating number may further comprise the steps in the present embodiment:

In step 201～202, when the measurement period that sets in advance expires, determine current all have the summation of the code word number that HSDPA user's sub-district takies; Judge whether the License code word number of base station counts summation greater than all code words that exist HSDPA user's sub-district to take, if, then continue execution in step 203, otherwise, execution in step 201 returned.

Here, dynamically control in order to carry out regular License sign indicating number each sub-district in the base station, system sets in advance measurement period, for example, when measurement period is 2ms, the then every just sub-district that has HSDPA user the execution once through 2ms added up. in addition, the shared code word number in sub-district is meant the number of the License code word of the actual use in this sub-district herein, when system's initial launch, the code word number average that each sub-district takies equals the backstage, base station and disposes License code word number to this sub-district, i.e. configuration code number of words H_cfg.

In step 203～204, deduct the code word that all sub-districts that have HSDPA user take by License code word number and count summation the base station, obtain the remaining code word in base station and count H_delta; And the maximum available codes number of words H_sig of the sub-district by each being existed HSDPA user deducts the code word number that takies, and the maximum that obtains this sub-district increases code word and counts H_add.

Maximum available codes number of words H_sig herein represents the number of the maximum operable License code words in sub-district, and to be radio network controller (RNC) reshuffle (Physical SharedChannel Reconfiguration) signaling by Physical Shared Channel is transferred to NodeB Application Part (NBAP) in the base station for it.As seen, even be that the License code word number of cell configuration surpasses its maximum available codes number of words H_sig, that part of License code word that exceeds maximum available codes number of words H_sig also can't be used in this sub-district.

In step 205, will not exist the code word number of HSDPA user's sub-district to reduce to 0, the remaining License code assignment in base station is given exist HSDPA user and the maximum code word that increases to count H_add greater than 0 sub-district.

Because not having the License code word of HSDPA user's sub-district is on the shelf in this measurement period, to not exist the License code word of HSDPA user's sub-district to lend the sub-district that has HSDPA user and can increase the License code word in this step, to reduce service needed can't be satisfied in these sub-districts because of the restricted number of License code word probability.

For the distribution of License code word, both can adopt mode according to the sub-district sequencing, also can adopt the mode of dividing equally.

The method of Fig. 3 for distributing the remaining License sign indicating number in base station in sub-district sequencing mode in the present embodiment.Referring to Fig. 3, this distribution method comprises:

In step 301, with first the sub-district in the base station with HSDPA user as current area.

Since each sub-district in the record of base station all to cell ID should be arranged, so in this step from sub-district that cell ID makes number one with HSDPA user.

In step 302, judge that whether the maximum increase code word of current area counts H_add greater than 0, if then execution in step 303; Otherwise, execution in step 309.

Maximum increase code word in current area in this step was counted H_add greater than 0 o'clock, showed that current area can increase the License code word again; Otherwise then expression needn't increase License code word number for current area.

In step 303～305, judge that the remaining code word of current base station counts H_delta and whether increase code word greater than the maximum of current area and count H_add, if then the code word number of current area is configured to equal the maximum available codes number of words H_sig of this sub-district, and continues execution in step 306; Otherwise the remaining code word of code word number and base station that takies that the code word number of current area is configured to equal this sub-district is counted the H_delta sum, and finishes this code assignment flow process.

When the remaining code word of current base station is counted H_delta and is increased code word and count H_add greater than the maximum of current area, show that the base station can farthest provide License code word for this sub-district, therefore the code word number of this sub-district is configured to and equals its maximum available codes number of words H_sig, the maximum that the code word number that is its increase equals this sub-district increases code word and counts H_add.Count maximum that H_delta is less than or equal to current area when increasing code word and counting H_add in the remaining code word of current base station, show that the remaining License code word in base station is few, whole remaining code words all can only be offered this sub-district, therefore the code word number that increases for this sub-district is that the remaining code word in base station is counted H_delta.

In step 306～307, to count the maximum increase code word that deducts this sub-district the H_delta by the remaining code word in base station from increase code word for current area before and count H_add, the remaining License code word in base station is counted H_delta under the acquisition present case; And judge that whether the remaining code word in base station obtained count H_delta greater than 0, if then execution in step 308, otherwise, finish this code assignment flow process.

Here the numerical value that performed reducing is exactly the remaining code word in base station is counted H_delta in fact upgrades, so that count H_delta according to the remaining code word in up-to-date base station, determine whether to continue to carry out this code assignment flow process, and the result who upgraded also is the foundation and the resource of postorder code assignment.

In step 308, judge whether to exist the sub-district that has HSDPA user that is not increased code word, if then execution in step 309; Otherwise, finish this code assignment flow process.

In step 309, turn to the next one to have HSDPA user's sub-district, and return execution in step 302.

The transfer of this step exists HSDPA user's sub-district promptly to mean this next sub-district as current area, after this with the operation of execution in step 302 to 309 once more, so that finish the License code assignment to the next one.

So far, finished the flow process of carrying out code assignment in the present embodiment with the sub-district sequencing.

Under this mode of Fig. 3, be preferably the cell ID arrangement sub-district that has HSDPA user formerly and increase License code word number, thereby realize the dynamic control of License code word, avoided not existing the waste of License code source in HSDPA user's the sub-district, reduce sub-district License code word and cause the possibility that can't satisfy business demand for want of, improved the reasonable usage degree of License code source in the base station effectively.

Fig. 4 shows the embodiment that carries out code assignment in the present embodiment according to the mode of dividing equally.In this manner, be the sub-district that has HSDPA user in the base station increases a License code word at every turn, exists HSDPA user's sub-district can't increase all that the remaining License code word in base station is exhausted in code word or this measurement period up to all again.As shown in Figure 4, this distribution method comprises:

In step 401, judge that whether the maximum increase code word of current area counts H_add greater than 0, if then be that current area increases a License code word, and continue execution in step 403; Otherwise, execution in step 407.

In step 403～405, the maximum increase code word from increase code word for current area before is counted and is deducted 1 the H_add, and the maximum that obtains this sub-district under the present case increases code word and counts H_add; The remaining code word in base station from increase code word for current area before is counted and is deducted 1 the H_delta, and the remaining License code word in base station is counted H_delta under the acquisition present case; Whether the remaining code word in base station that judgement is obtained counts H_delta greater than 0, if then execution in step 407, otherwise, finish this code assignment flow process.

In step 406, judge whether that all sub-districts that have HSDPA user all can't increase the License code word, if then finish this code assignment flow process; Otherwise, execution in step 407.

Judge whether in this step that all sub-districts that have HSDPA user all can't increase the License code word and be: exist the maximum of HSDPA user's sub-district to increase code word at all and count H_add and be equal under 0 the situation, judge that then all sub-districts that have HSDPA user all can't increase the License code word.

In step 407, turn to the next one to have HSDPA user's sub-district, and return execution in step 401.

So far, finished the flow process of carrying out code assignment in the present embodiment in the mode of dividing equally.

Under this mode of Fig. 4, each exists HSDPA user's sub-district all to have an opportunity to increase the License code word. like this, the remaining License code word in base station can farthest be distributed in the sub-district that has HSDPA user in this base station in the current measurement period, make the sub-district of One's name is legion to improve traffic handing capacity because of increasing License code word number, and reduced sub-district License code word and cause the possibility that can't satisfy business demand for want of, avoid not existing the waste of License code source in HSDPA user's the sub-district, also improved the reasonable usage degree of License code source in the base station effectively.

Embodiment 2

The core concept of present embodiment is that the residue License code assignment in the sub-district that the code word utilance is lower gives the code word utilance higher and can increase the sub-district of code word number.Fig. 5 shows the flow chart of the control method of License sign indicating number in the embodiment of the invention 2; Fig. 6 and Fig. 7 are the method flow diagram that distributes the remaining License sign indicating number in base station in the present embodiment.

Present embodiment sets in advance code word utilance Lower Threshold η _LWith code word utilance Upper threshold η _H

Referring to Fig. 5, the control method of License sign indicating number may further comprise the steps in the present embodiment:

In step 501, when the measurement period that sets in advance expires, determine the code word utilance of current all sub-districts.

For each sub-district of using the License sign indicating number, code word utilance η is: η=F/R.Wherein, F represents the actual License code word number that takies in sub-district in the current measurement period, and R represents to be in the current measurement period License code word number of this cell allocation.At the initial stage of system's operation, assigned code number of words R equals configuration code number of words H_cfg.

In step 502, according to the code word utilance and the code word utilance Lower Threshold η of each sub-district _LWith code word utilance Upper threshold η _H, determine the nervous set of cells Cell_H of low code word utilance set of cells Cell_L and code word, and sorted in the sub-district among the nervous set of cells Cell_H of code word according to the code word utilance.

In this step with code word utilance η and the code word utilance Lower Threshold η L and the code word utilance Upper threshold η of each sub-district _HCompare, if less than code word utilance Lower Threshold η _L, then this sub-district is put into low code word utilance set of cells Cell_L; If greater than code word utilance Upper threshold η _H, then this sub-district is put into the nervous set of cells Cell_H of code word.After all sub-districts are sorted out, to be sorted in the sub-district among the nervous set of cells Cell_H of code word, the sub-district that the code word utilance is high comes the front.

In step 503, reduce the code word number of each sub-district among the low code word utilance set of cells Cell_L, the code word number that reduces equals R (1-η) and rounds, and the remaining code word in base station in the current measurement period is counted H_delta is defined as equaling the code word that all sub-districts are reduced and counts sum.

In current measurement period, all there is remaining License code word in each sub-district among the low code word utilance set of cells Cell_L, the remaining code word number in each sub-district is the numerical value that R (1-η) rounds, therefore in this step these remaining License code words are taken out, so that in subsequent step, these remaining code assignment are given sub-district among the nervous set of cells Cell_H of code word.

In step 504, the remaining code word in base station is counted H_delta distribute to sub-district among the nervous set of cells Cell_H of code word.

Because the code word utilance of the sub-district among the nervous sub-district Cell_H of code word is higher, the situation that the code word number does not satisfy business demand appears easily, therefore give these sub-districts with License code assignment idle in the base station in this step, to reduce service needed can't be satisfied in these sub-districts because of the restricted number of License code word probability.

For the distribution of License code word, both can adopt the preferential mode of the high person of code word utilance, also can adopt the mode of dividing equally.

The method of Fig. 6 for distributing the remaining License sign indicating number in base station in the preferential mode of the high person of code word utilance in the present embodiment.Referring to Fig. 6, this distribution method comprises:

In step 601, with first sub-district among the nervous set of cells Cell_H of code word as current area.

Owing in above-mentioned step 502, sorted in the sub-district among the nervous sub-district Cell_H of code word, so the current area in this step is the highest sub-district of code word utilance according to the code word utilance.

In step 602～603, by the maximum available codes number of words H_sig of current area being deducted the assigned code number of words R of this sub-district, the maximum that obtains current area increases code word and counts H_add; The maximum of judging current area increases code word and whether counts H_add greater than 0, if, then continue execution in step 604, otherwise, execution in step 610.

Count H_add greater than 0 if the maximum of current area increases code word, show that then current area can increase the License code word; Otherwise, represent that then the assigned code number of words R of current area has reached its maximum available codes number of words H_sig, therefore can't increase License code word number again.

In step 604～605, judge that the remaining code word in base station counts H_delta and whether increase code word greater than the maximum of current area and count H_add, if then execution in step 606; Otherwise, count H_delta code word for current area increases the remaining code word in base station, and finish this code assignment flow process.

Counting maximum that H_delta is less than or equal to current area in the remaining code word in base station increases code word and counts under the situation of H_add, it is less to show that the remaining code word in present base station is counted H_delta, only can increase the License code word for current area, therefore, the remaining code word in base station is counted H_delta and all distribute to current area.At this moment, the assigned code number of words R of current area becomes the assigned code number of words R that increases before the code word and adds that the remaining code word in base station counts H_delta.

In step 606, the assigned code number of words R of current area is configured to equal the maximum available codes number of words of this sub-district.

Counting H_delta in the remaining code word in base station counts under the situation of H_add greater than the maximum increase code word of current area, showing has code word to be allocated to be enough to the code word number of current area is increased to its maximum available codes number of words H_sig in the present base station, therefore, the code word number that increases for current area in this step equals the maximum available codes number of words H_add of this sub-district.

In step 607～608, to count the maximum increase code word that deducts this sub-district the H_delta by the remaining code word in base station from increase code word for current area before and count H_add, the remaining Lisence code word in base station is counted H_delta under the acquisition present case; And judge that whether the remaining code word in base station obtained count H_delta greater than 0, if then execution in step 609, otherwise, finish this code assignment flow process.

In step 609, judge that whether current area is last sub-district among the nervous set of cells Cell_H of code word, if then finish this code assignment flow process; Otherwise, execution in step 610.

When current area came end among the nervous set of cells Cell_H of code word, the operation that code word increases had been carried out in the sub-district that can increase code word among the nervous set of cells Cell_H of code word all, has therefore finished this code assignment.

In step 610, turn to the next sub-district among the nervous set of cells Cell_H of code word, and return execution in step 602.

Turn to the next sub-district among the nervous set of cells Cell_H of code word promptly to mean this next sub-district in this step as current area, after this with the operation of execution in step 602 to 609 once more, so that finish the License code assignment.

So far, finished the flow process of carrying out code assignment in the present embodiment in the preferential mode of the high person of code word utilance.

Under this mode of Fig. 6, because the License code source is comparatively nervous in the higher sub-district of code word utilance, therefore be preferably the higher sub-district of code word utilance and increase License code word number, thereby realize the dynamic control of License code word, avoided the waste of code source in the lower sub-district of code word utilance, reduce the higher sub-district of code word utilance License code word and cause the possibility that can't satisfy business demand for want of, improved the reasonable usage degree of License code source in the base station effectively.

Fig. 6 shows the embodiment that carries out code assignment in the present embodiment according to the mode of dividing equally. in this manner, the sub-district that at every turn is among the nervous set of cells Cell_H of code word increases a License code word, all sub-districts in this set can't increase all that the remaining License code word in base station is exhausted in code word or this measurement period, as shown in Figure 7, this distribution method comprises:

In step 701, with first sub-district among the nervous set of cells Cell_H of code word as current area.

In step 702～704, deduct its assigned code number of words R by maximum available codes number of words H_sig with current area, the maximum of obtaining this sub-district increases code word and counts H_add; The maximum of judging current area increases code word and whether counts H_add greater than 0, if then execution in step 705, otherwise, current area is deleted from the nervous set of cells Cell_H of code word, and execution in step 709.

Increasing code word in the maximum of current area counts H_add and equals under 0 the situation, show that this sub-district can't increase the License code word again, therefore in follow-up cyclic process, unnecessary judgement is carried out in this sub-district, then it is deleted from the nervous set of cells Cell_H of code word.

In step 705～707, for current area increases a License code word, and deduct 1 among the H_add the maximum increase code word number from increase code word for current area before, the maximum that obtains this sub-district under the present case increases code word and counts H_add; The remaining code word in base station from increase code word for current area before is counted and is deducted 1 the H_delta, and the remaining License code word in base station is counted H_delta under the acquisition present case; Whether the remaining code word in base station that judgement is obtained counts H_delta greater than 0, if then execution in step 708, otherwise, finish this code assignment flow process.

For the real-time update that can realize that sub-district maximum increase code word is counted H_add and base station residue code number of words H_delta, after the sub-district is increased the code word number, all calculate the up-to-date value of above-mentioned two amounts at every turn.

In step 708, judge that whether current area is last sub-district among the nervous set of cells Cell_H of code word, if then return execution in step 701; Otherwise, execution in step 709.

When current area comes the end of the nervous set of cells Cell_H of code word,, be followed successively by the operation that carry out each sub-district increases by 1 code word then once more from first sub-district of this set.

In step 709, turn to the next sub-district among the nervous set of cells Cell_H of code word, and return execution in step 702.

Under this mode of Fig. 7, it is higher and can increase in the sub-district of code word that the remaining code word number in base station in the current measurement period farthest is distributed in the code word utilance, make the sub-district of One's name is legion to improve traffic handing capacity because of increasing License code word number, and reduced sub-district License code word and cause the possibility that can't satisfy business demand for want of, avoid the waste of License code source in the lower sub-district of code word utilance, also improved the reasonable usage degree of License code source in the base station effectively.

Embodiment 3

The core concept of present embodiment is the sub-district that the residue License code assignment in the sub-district that the code word utilance is lower is higher to the code word utilance, can increase the code word number and once the code word of self be lent out.Fig. 8 shows the flow chart of the control method of License sign indicating number in the embodiment of the invention 2; Fig. 9 is the method flow diagram that distributes the remaining License sign indicating number in base station in the present embodiment.

Identical with embodiment 2, present embodiment also sets in advance code word utilance Lower Threshold η _LWith code word utilance Upper threshold η _H

Referring to Fig. 8, the control method of License sign indicating number may further comprise the steps in the present embodiment:

In step 801, when the measurement period that sets in advance expires, determine the code word utilance of current all sub-districts.

In this step, code word utilance η equals current area actual code word that takies in current measurement period and counts F divided by the initial stage of the assigned code number of words R. of this sub-district in current measurement period in system's operation, and assigned code number of words R equals configuration code number of words H_cfg.

In step 802, according to the code word utilance and the code word utilance Lower Threshold η of each sub-district _LWith code word utilance Upper threshold η _HDetermine low code word utilance set of cells Cell_L, the nervous set of cells Cell_H of code word, the nervous set of cells Cell_U of high priority code word and middle code word utilance set of cells Cell_M, and, sorted in the sub-district among the nervous set of cells Cell_U of high priority code word, the nervous set of cells Cell_H of code word and the middle code word utilance set of cells Cell_M according to code word utilance order from high to low.

This step is sorted out all sub-districts in the base station, is about to the code word utilance η and the code word utilance Upper threshold η of each sub-district _HWith code word utilance Lower Threshold η _LCompare.If code word utilance η is less than code word utilance Lower Threshold η _L, then this sub-district is put into low code word utilance set of cells Cell_L; If code word utilance η is at code word utilance Upper threshold η _HWith code word utilance Lower Threshold η _LBetween, then this sub-district is put into code word utilance set of cells Cell_M; If code word utilance η is greater than code word utilance Upper threshold η _HAnd the assigned code number of words R of this sub-district is less than its configuration code number of words, show that this sub-district once lent the License code word of self other sub-districts and use, because this moment, the code word utilance of this sub-district was higher, therefore should preferentially fetch the License code word of once lending, then this sub-district be put into the nervous set of cells Cell_U of high priority code word; If code word utilance η is greater than code word utilance Upper threshold η _H, and the assigned code number of words R of this sub-district then puts into this sub-district the nervous set of cells Cell_H of code word more than or equal to its configuration code number of words.

After each sub-district all having been carried out classification, to be sorted in the sub-district among the nervous set of cells Cell_U of high priority code word, the nervous set of cells Cell_H of code word and the middle code word utilance set of cells Cell_M, the sub-district that the code word utilance is high comes the front.

In step 803, reduce the code word number of each sub-district among the low code word utilance set of cells Cell_L, the code word number that reduces equals R (1-η) and rounds, and the remaining code word in base station in the current measurement period is counted H_delta is defined as equaling the code word that all sub-districts are reduced and counts sum.

Each sub-district in this step from low code word utilance set of cells Cell_L is taken out R (1-η) and is rounded a code word, the numerical value that is about to the assigned code number of words R of these sub-districts reduces R (1-η) and rounds, so that the code assignment that in subsequent step these is removed is given the sub-district that needs to increase the code word number.

In step 804, counting the assigned code number of words of sub-district among H_delta and the middle code word utilance set of cells Cell_M according to the remaining code word in base station, is that the sub-district among nervous set of cells Cell_U of high priority code word and the nervous set of cells Cell_H of code word increases License code word number.

As shown in Figure 9, the method for code assignment comprises following operation in this step:

In step 901～902, judge that the remaining code word in base station counts H_delta and whether equal sub-district number among the nervous set of cells Cell_U of high priority code word, if, then for each sub-district among the nervous set of cells Cell_U of high priority code word all increases a License code word, and finish the flow process of this code assignment; Otherwise, execution in step 903.

If the remaining code word in base station is counted H_delta and just can mean allocation be given all sub-districts among the nervous set of cells Cell_U of high priority code word in the current measurement period, then after increasing code word, no longer there is remaining License code word in the base station for these sub-districts.

In step 903～904, judge that the remaining code word in base station counts H_delta whether greater than the sub-district number among the nervous set of cells Cell_U of high priority code word, if, then according to the sequencing of sub-district, be the code word of sub-district increase among nervous set of cells Cell_U of high priority code word and the nervous set of cells Cell_H of code word, counting H_delta until the remaining code word in base station is 0 at every turn; Otherwise, execution in step 905.

In step 905,, and this H_delta sub-district is deleted from the nervous set of cells of high priority code word for preceding H_delta sub-district among the nervous set of cells Cell_U of high priority code word all increases a code word.

Be not enough to the equal timesharing in sub-district in the nervous set of cells Cell_U of high priority code word at the remaining code word number in base station, be preferably the higher sub-district increase code word number of code word utilance in this set.

In step 906, therefrom take out code word among the nervous sub-district Cell_H of code word utilance sub-district Cell_M or code word, for the residue sub-district among the nervous set of cells Cell_U of high priority code word all increases a code word.

Owing to have the sub-district that does not increase the code word number among the nervous set of cells Cell_U of high priority code word, and do not have remaining code word in the base station at present, consider and still have idle code word in the sub-district among the code word utilance set of cells Cell_M, therefore this step is by the code word number of the sub-district among the code word utilance set of cells Cell_M in reducing, and coming all increases by 1 code word for the sub-district that does not increase the code word number among the nervous set of cells Cell_U of high priority code word.Under the situation that the code word of taking out uses up, from the nervous set of cells Cell_H of code word, take out code word again in the sub-district among the code word utilance set of cells Cell_M therefrom.

Figure 10 when count the sub-district among the nervous set of cells Cell_U greater than the high priority code word, distributes to the remaining code word number in base station the method flow diagram of nervous sub-district Cell_U of high priority code word and the nervous sub-district Cell_H of code word at the remaining code word number in base station in the step 904 of present embodiment.

As shown in figure 10, the code assignment in the step 904 comprises following operation:

In step 1001, code word is put into according to code word utilance order from high to low in sub-district among the nervous set of cells Cell_U of high priority code word increases set of cells Cell_N, and again code word being put into successively according to code word utilance order from high to low in the sub-district among the nervous set of cells Cell_H of code word increases set of cells Cell_N.

In order to guarantee that each sub-district is in the priority that increases on the code word among the nervous set of cells Cell_U of high priority code word, increase among the set of cells Cell_N in code word, at first being the sub-district among the nervous set of cells Cell_U of high priority code word that arranges from high to low according to the code word utilance, then is the sub-district among the nervous set of cells Cell_H of code word that arranges from high to low according to the code word utilance.

In step 1002, code word is increased first sub-district among the set of cells Cell_N as current area.

In step 1003～1005, by the maximum available codes number of words H_sig of current area being deducted the assigned code number of words R of this sub-district, the maximum that obtains current area increases code word and counts H_add; And the maximum of judging current area increases code word and whether counts H_add greater than 0, if, then continue execution in step 1006, otherwise, current area increased the set of cells Cell_N from code word delete, and execution in step 1010.

Increasing code word in the maximum of current area counts H_add and equals can't increase the License code word again under 0 the situation.In follow-up circulation, unnecessary judgement is carried out in this sub-district, therefore this sub-district is increased the set of cells Cell_N from code word and delete.

In step 1006～1008, be License code word of current area increase, and deduct 1 the H_add that the maximum increase code word that obtains this sub-district under the present case is counted H_add from counting for the maximum increase code word before the current area increase code word; The remaining code word in base station from increase code word for current area before is counted and is deducted 1 the H_delta, and the remaining code word in base station is counted H_delta under the acquisition present case; Whether the remaining code word in base station that judgement is obtained counts H_delta greater than 0, if then execution in step 1009, otherwise, finish this code assignment flow process.

In step 1009, judge that whether current area is last sub-district among the nervous set of cells Cell_H of code word, if then return execution in step 1002; Otherwise, execution in step 1010.

When current area is in the end of the nervous set of cells Cell_H of code word,, be followed successively by the operation that carry out each sub-district increases by 1 code word then once more from first sub-district of this set.

In step 1010, turn to the next sub-district among the nervous set of cells Cell_H of code word, and return execution in step 1003.

So far, finished in the present embodiment at the remaining code word number in base station when count the sub-district among the nervous set of cells Cell_U greater than the high priority code word, base station remaining code word number has been distributed to the flow process of nervous sub-district Cell_U of high priority code word and the nervous sub-district Cell_H of code word.

Figure 11 illustrates in the step 906 of present embodiment at the remaining code word number in base station when count the sub-district among the nervous set of cells Cell_U smaller or equal to the high priority code word, base station remaining Licnese code word number is distributed to the method flow diagram of the nervous sub-district of high priority code word in the mode of dividing equally.

As shown in figure 11, the code assignment in the step 906 comprises following operation:

In step 1101～1103, with first sub-district among the nervous set of cells Cell_U of high priority code word as current area; By the maximum available codes number of words H_sig of current area being deducted the assigned code number of words R of this sub-district, the maximum that obtains current area increases code word and counts H_add; And, judge that whether the maximum increase code word of current area counts H_add greater than 0, if, then continue execution in step 1104, otherwise, execution in step 1108.

In step 1104, whether code word utilance set of cells Cell_M is empty in the judgement, if then execution in step 1105; Otherwise, execution in step 1107.

In step 1105～1106, judge whether the nervous set of cells Cell_H of code word is empty, if then finish this code assignment flow process; Otherwise, the assigned code number of words of last sub-district among the nervous set of cells Cell_H of code word is subtracted 1, the sub-district that is reduced code word is deleted from the nervous set of cells Cell_H of code word, and for current area increases a code word, then execution in step 1108.

In middle code word utilance set of cells Cell_M, do not exist under the situation of sub-district, in order to alleviate the code word pressure of sub-district among the nervous set of cells Cell_U of high priority code word, take out a code word in the sub-district that the code word utilance is minimum from the nervous set of cells Cell_H of code word, distribute to current area.In addition, because the code word of each sub-district is also comparatively nervous among the nervous set of cells Cell_H of code word, only from each sub-district of this set, extract a code word in the present embodiment, therefore, delete from the nervous set of cells Cell_H of code word extracting code word sub-district afterwards, in order to avoid from same sub-district, extract unnecessary one code word.

In step 1107, the assigned code number of words of last sub-district among the middle code word utilance set of cells Cell_M is subtracted 1, the sub-district that is reduced code word is therefrom deleted among the code word utilance set of cells Cell_M, and for current area increases a code word, then execution in step 1108.

In step 1108, current area is deleted from the nervous set of cells Cell_U of high priority code word, and judge whether the nervous set of cells Cell_H of high priority code word is empty, if then finish this code assignment flow process; Otherwise, return execution in step 1101.

After increasing code word, all it is deleted from the nervous set of cells Cell_U of high priority code word at every turn, promptly only keep the sub-district that had not increased code word in the nervous sub-district of high priority code word for current area.

So far, finished in the present embodiment at the remaining code word number in base station when count the sub-district among the nervous set of cells Cell_U smaller or equal to the high priority code word, base station remaining License code word number has been distributed to the flow process of the nervous sub-district of high priority code word in the mode of dividing equally.

In the present embodiment, all sub-districts all increase under the situation of a code word in the remaining code word number in base station is enough to for high priority code word anxiety set of cells, then give sub-district among nervous set of cells Cell_U of high priority code word and the nervous set of cells Cell_H of code word with code assignment in the mode of dividing equally. concrete allocation order is: according to code word utilance order from high to low earlier be sub-district increase code word among the nervous set of cells Cell_U of high priority code word, when still having remainder codewords, be that sub-district among the nervous set of cells Cell_H of code word increases code word according to code word utilance order from high to low again. in addition, can't all increase under the situation of a code word all sub-districts among the nervous set of cells Cell_U for the high priority code word at the remaining code word number in base station, begin to take out successively a code word by the minimum sub-district of code word utilance among middle code word utilance set of cells Cell_M or the nervous set of cells Cell_H of code word, increase and give the sub-district that does not increase code word among the nervous set of cells Cell_U of high priority code word. as seen, present embodiment can be alleviated the higher and nervous situation of code word sub-district that once the code word of self is lent out of code word utilance effectively.
