Step 101, obtain the actual use of all users Channel Elements quantity information in the base station according to the described actual Channel Elements quantity information that uses, and, the Channel Elements quantity allotted of each scheduling entity is carried out dynamic adjustments according to the actual Channel Elements licensed number information of using Channel Elements quantity information and predefined base station of all users in the described base station;

The base station comprises in receiving the scheduling entity Channel Elements use statistical information of each scheduling entity transmission

After the information, each scheduling entity is sent The actual use of all users Channel Elements quantity information is first statistical information in this base station to obtain to carry out read group total, and the size of " LICENSE CE " information of comparison first statistical information and predefined base station, judge which kind of dynamic adjustments mode of selection realizes that " LICENSE CE " carries out dynamic assignment between a plurality of scheduling entity, to reach the actual use of all users Channel Elements restricted number in the base station in reasonable range.

According to the Channel Elements licensed number information of first statistical information and predefined base station the Channel Elements quantity allotted of each scheduling entity is carried out dynamic adjustments and can comprise following several situation:

First kind of situation, obtain first statistical information according to the described actual Channel Elements quantity information that uses, if surpassing described Channel Elements licensed number information, described first statistical information reaches default thresholding, then to the adjusting that dynamically descends of the Channel Elements quantity allotted of each scheduling entity, be in particular that the actual use of all users Channel Elements quantity information is that first statistical information is above " LICENSE CE " in the base station, and when having reached predetermined threshold value, for example first statistical information has reached 110% o'clock of Channel Elements licensed number information, the Channel Elements resource that the declaratives scheduling entity provides for the user has surpassed budget and has made the Channel Elements sum that all users use in the base station exceed tolerance band, the Channel Elements quantity allotted that the reply scheduling entity the is distributed adjusting that dynamically descends.

Second kind of situation, obtain first statistical information according to the described actual Channel Elements quantity information that uses, if surpassing described first statistical information, described Channel Elements licensed number information reaches default thresholding, then to the adjusting of dynamically rising of the Channel Elements quantity allotted of each scheduling entity, be in particular that the actual use of all users Channel Elements quantity information is that first statistical information is lower than " LICENSE CE " in the base station, and when being lower than predetermined threshold value, for example first statistical information has reached 90% o'clock of Channel Elements licensed number information, the adjusting of will dynamically rising to the Channel Elements quantity allotted of distributing for scheduling entity.

The third situation, obtain first statistical information according to the described actual Channel Elements quantity information that uses, if the default thresholding of the difference no show of described first statistical information and described Channel Elements licensed number information, then the Channel Elements quantity allotted of each scheduling entity being carried out dynamic fairness regulates, can not reach for the difference of first statistical information and " LICENSE CE " particularly in the time of can dynamically descending adjusting or dynamically rise adjusting, if the Channel Elements quantity allotted of distributing for scheduling entity is not regulated and to produce the inequitable phenomenon generation of Channel Elements quantity that each scheduling entity is distributed, for example the user that priority is high is positioned on the scheduling entity, the user that priority is low is positioned on another scheduling entity, if the LICENSE CE that the user place scheduling entity that priority is high is distributed is few, the LICENSE CE that distributes on the low user place scheduling entity of priority is many, like this, if do not adjust, can keep this state all the time, cause the high user rate of priority not increase.Can carry out dynamic fairness to the Channel Elements quantity allotted of each scheduling entity this moment and regulate, make the Channel Elements resource allocation have more fairness.

Step 102 is to the Channel Elements quantity allotted information of the corresponding described dynamic adjustments gained of each scheduling entity transmission.

Finish the dynamic rising adjusting or dynamic descend adjusting or dynamic fairness adjusting of Channel Elements distribution in the base station after, the quantity of the up-to-date Channel Elements that once distributes for each scheduling entity to be informed each scheduling entity, make each scheduling entity provide the Channel Elements resource service for the user who belongs to this scheduling entity according to Channel Elements quantity allotted information for its distribution.

Fig. 2 regulates Channel Elements quantity embodiment flow chart for dynamically descending in the channel unit distribution method of the present invention, and this method comprises as shown in Figure 2:

Step 200 receives the scheduling entity Channel Elements use statistical information that a plurality of scheduling entity send, and gathers;

The actual use CE quantity that scheduling entity is added up all users in this scheduling entity by the cycle is

Scheduling entity can be expressed as for the CE quantity information that the user distributes

Non-service link can be seized CE quantity can be expressed as NonServiceCE _m, select the interior preempting priority of this scheduling entity simultaneously and count PRI _mA highest service link and the seized CE quantity of this service link can be expressed as ServiceCE _m, use statistical information to report base station system as the scheduling entity Channel Elements in the lump, base station system gathers each scheduling entity reported data:

A, obtain first statistical information, promptly calculate the current actual CE of use of all users and count summation according to the described actual Channel Elements quantity information that uses: ${\mathrm{CE}}^{\mathrm{Used}}=\mathrm{\Σ}{\mathrm{CE}}_m^{\mathrm{Used}}(m=1...M);$

The seized CE number of all non-service links in b, the calculation base station:

NonServiceCE _total＝∑NonServiceCE _m，(m＝1...M)；

According to the above data that gather, judge whether the current actual CE of use quantity summation surpasses " LICENSE CE " restriction, is to need rise CE, still need fall CE, and at the concrete number of each scheduling entity rising or decline CE.In the present embodiment, because current reality uses CE quantity summation to surpass " LICENSE CE ", therefore to carry out the dynamic decline of Channel Elements quantity and regulate processing.

Step 201 according to the Channel Elements licensed number information of described first statistical information and predefined base station, obtains the Channel Elements decline quantity information of base station;

If CE ^UsedSurpass " LICENSE CE " and reach default thresholding, for example CE ^UsedReach " LICENSE CE " 110% o'clock, write down the current value CE that exceeds ^ExceedEqual CE ^UsedAnd the difference between " LICENSECE ", and start the algorithm that falls CE, the Channel Elements decline quantity information CE of calculation base station ^Dec=CE ^Exceed

Step 202 according to Channel Elements decline quantity information and each scheduling entity Channel Elements use statistical information of described base station, obtains the Channel Elements decline quantity information of each scheduling entity correspondence;

When each scheduling entity decline CE of calculating counts, there is NonServiceCE if use the Channel Elements the seized quantity of the non-service link that comprises in the statistical information to learn according to the scheduling entity Channel Elements _mScheduling entity greater than 0, the CE number of the non-service link place scheduling entity that then descends, the Channel Elements decline quantity information of this scheduling entity correspondence can use the Channel Elements the seized quantity information of the non-service link that comprises in the statistical information to obtain according to Channel Elements decline quantity information and each scheduling entity Channel Elements of base station, such as, can be calculated as follows: ${\mathrm{CE}}_m^{\mathrm{Dec}}=\mathrm{MIN}[{\mathrm{NonServeceCE}}_m,(\mathrm{NonService}{\mathrm{CE}}_m/\mathrm{NonService}{\mathrm{CE}}_{\mathrm{total}})*{\mathrm{CE}}^{\mathrm{Dec}}],$ Decimal point rounds up, wherein NonServiceCE _TotalThe Channel Elements seized quantity information sum for the non-service link of all scheduling entity correspondences.

If use the Channel Elements the seized quantity of the non-service link that comprises in the statistical information to learn that the Channel Elements the seized quantity information of the non-service link that does not have correspondence is greater than zero scheduling entity, the i.e. NonServiceCE of all scheduling entity according to the scheduling entity Channel Elements _mAll equal 0, then press PRI _mEach scheduling entity is sorted, select a scheduling entity that numerical value is the highest to calculate the CE number that descends, if the highest PRI _mScheduling entity have a plurality ofly, then can adopt at random selection mode to select one of them, it all is same can avoiding each scheduling entity of selecting to descend.The CE decline quantity information of this scheduling entity correspondence can be counted PRI according to selected preempting priority in the scheduling entity _mThe Channel Elements decline quantity information of seized CE quantity of one of the highest service link and base station obtains, such as, can be calculated as follows: ${\mathrm{CE}}_m^{\mathrm{Dec}}=\mathrm{MIN}[{\mathrm{ServiceCE}}_m,{\mathrm{CE}}^{\mathrm{Dec}}].$

Step 203 is used the Channel Elements quantity information as user's distribution that comprises in the statistical information according to the Channel Elements decline quantity information of each scheduling entity and the scheduling entity Channel Elements of correspondence, obtains the Channel Elements quantity allotted information of each scheduling entity correspondence;

After obtaining the CE decline quantity information of selected scheduling entity correspondence, and be the Channel Elements quantity information that the user distributes, obtain the Channel Elements quantity allotted information of each scheduling entity correspondence, calculate acquisition such as using following formula in conjunction with scheduling entity: ${\mathrm{CE}}_m^{\mathrm{License}}={\mathrm{CE}}_m^{\mathrm{Alloc}}-{\mathrm{CE}}_m^{\mathrm{Dec}},$ For other scheduling entity of regulating that dynamically do not descend, can still keep the Channel Elements quantity allotted information in last cycle.Because the CE quantity of distributing for each scheduling entity may change each time, just current period is that the last CE quantity for this scheduling entity distribution of CE quantity contrast that scheduling entity is distributed may be different, and the described last cycle just is meant with respect to a last CE quantity assignment period with regard to the current period.

Step 204 sends the Channel Elements quantity allotted information that gained is regulated in corresponding dynamic decline to each scheduling entity.

Because the Channel Elements quantity allotted information of this cycle degree of exchanging entity has been done dynamic decline and has been regulated, therefore will be with up-to-date each scheduling entity of Channel Elements quantity allotted information notification of once distributing of this cycle for each scheduling entity, can be the scheduling entity transmitting channel unit quantity allotted information of regulating to dynamically descending particularly, described Channel Elements quantity allotted information is this scheduling entity poor for the Channel Elements decline quantity information of the Channel Elements quantity information of user distribution and this scheduling entity; The scheduling entity transmitting channel unit quantity allotted information of regulating to dynamically not descending, the Channel Elements quantity allotted information in described Channel Elements quantity allotted information and last cycle is identical.

The Channel Elements quantity allotted of scheduling entity dynamically descends to regulating can also several different methods, for example can report by scheduling entity

The CE number that pro rata distribution descends; Can also allow scheduling entity can seize the CE summarizing and reporting to all service links, then according to the value of summarizing and reporting, pro rata distribution decline CE number etc. between each scheduling entity.

In the channel unit distribution method that present embodiment provides; all users' actual use Channel Elements quantity information surpasses the default Channel Elements licensed number information in base station and satisfies and carry out the Channel Elements quantity allotted when dynamically descending the condition of regulating in the base station; select the scheduling entity at non-service link place or the object that the highest scheduling entity of preempting priority is regulated as dynamic decline; and the Channel Elements quantity allotted after will descending is informed the decline object; the Channel Elements quantity allotted of other scheduling entity remains unchanged; the CE number that makes interior all users of current base station system use is limited in the zone of reasonableness of " LICENSE CE " permission, with protection equipment supplier's interests.

Fig. 3 regulates Channel Elements quantity embodiment flow chart for dynamically rising in the channel unit distribution method of the present invention, and this method comprises as shown in Figure 3:

Step 300 receives the scheduling entity Channel Elements use statistical information that a plurality of scheduling entity send, and gathers;

The actual use CE quantity that scheduling entity is added up all users in this scheduling entity by the cycle is

Scheduling entity can be expressed as for the CE quantity information that the user distributes

Non-service link can be seized CE quantity can be expressed as NonServiceCE _m, select the interior preempting priority of this scheduling entity simultaneously and count PRI _mA highest service link and the seized CE quantity of this service link can be expressed as ServiceCE _m, use statistical information to report base station system as the scheduling entity Channel Elements in the lump, base station system gathers each scheduling entity reported data:

A, obtain first statistical information, promptly calculate the current actual CE of use of all users and count summation according to the described actual Channel Elements quantity information that uses: ${\mathrm{CE}}^{\mathrm{Used}}=\mathrm{\Σ}{\mathrm{CE}}_m^{\mathrm{Used}}(m=1...M);$

The seized CE number of all non-service links in b, the calculation base station:

NonServiceCE _total＝∑NonServiceCE _m，(m＝1...M)；

Base station system finds that Channel Elements licensed number information surpasses first statistical information and reaches default thresholding, i.e. CE after gathering each scheduling entity reported data ^UsedReach certain default thresholding, for example CE less than " LICENSE CE " ^UsedOnly be 90% o'clock of License Value, start the algorithm that rises CE.

Step 301 according to the Channel Elements licensed number information of described first statistical information and predefined base station, obtains the Channel Elements rising percent information of base station;

Calculate this earlier and need rise the ratio of CE, target is to make actual use CE number reach " LICENSECE " allowed values CE ^Total, can be according to the Channel Elements licensed number information of first statistical information and predefined base station, obtain the Channel Elements rising percent information of base station, such as can application of formula SchAddCERatio=(CE ^Total-CE ^Used)/CE ^UsedObtain.

Step 302, according to the Channel Elements quantity allotted information in described last cycle of the Channel Elements quantity allotted information in the last cycle scheduling entity different and the Channel Elements rising percent information of described base station, obtain the Channel Elements rising quantity information of described scheduling entity correspondence with original allocation quantity;

Behind the Channel Elements rising percent information SchAddCERatio that obtains the base station, determine the adjusting of dynamically rising of Channel Elements quantity allotted at which scheduling entity, selecting base station in the last cycle in the present embodiment be that Channel Elements quantity allotted and the base station of its distribution is that the inconsistent scheduling entity of original allocation quantity of its distribution is as the adjustment object, described original allocation quantity is the CE quantity that the base station is distributed for this scheduling entity under initial condition, the base station is after adopting dynamic assignment CE resource in subsequent process, the CE quantity of distributing for scheduling entity may change, so present embodiment is to select scheduling entity that the CE quantity allotted changes as controlled plant.Determining behind the controlled plant to determine that again this need rise the number of CE, can be according to the Channel Elements rising percent information of base station and wait to regulate the Channel Elements quantity allotted information in the last cycle of scheduling entity correspondence and obtain, such as by formula: ${\mathrm{CE}}_m^{\mathrm{Add}}={\mathrm{CE}}_m^{\mathrm{License}\′}*\mathrm{SchAddCERatio},$ SchAddCERatio, and round up, wherein

Channel Elements quantity allotted information for last cycle of this scheduling entity correspondence.Certainly owing to the CE allotment and the original allocation number that have a plurality of scheduling entity are inconsistent, therefore determined controlled plant might exist a plurality of.

Step 303 according to the Channel Elements quantity allotted information and the original allocation quantity in the Channel Elements rising quantity information of described scheduling entity correspondence, last cycle, obtains the Channel Elements quantity allotted information of described scheduling entity correspondence;

In above-mentioned steps, acquire after needing to rise the quantity of CE on the scheduling entity, determine interim Channel Elements quantity allotted information of distributing this week for this scheduling entity, can according to the Channel Elements quantity allotted information in original allocation quantity, last cycle of scheduling entity, and the Channel Elements rising quantity information of scheduling entity correspondence obtain, such as passing through formula ${\mathrm{CE}}_m^{\mathrm{License}}=\mathrm{MIN}[{\mathrm{CE}}_m^{\mathrm{Init}},{\mathrm{CE}}_m^{\mathrm{License}\′}+{\mathrm{CE}}_m^{\mathrm{Add}}]$ Obtain the Channel Elements quantity allotted information of scheduling entity correspondence, wherein

Be original allocation quantity,

Be the Channel Elements quantity allotted information in last cycle of scheduling entity, Channel Elements rising quantity information for the scheduling entity correspondence.From formula as can be seen, if the Channel Elements quantity allotted information in last cycle and Channel Elements rising quantity information sum if be higher than original allocation quantity, then select the less original allocation quantity of numerical value as interim Channel Elements quantity allotted information for scheduling entity distribution this week.

Step 304 sends the Channel Elements quantity allotted information that gained is regulated in corresponding dynamic rising to each scheduling entity.

Because the Channel Elements quantity allotted information of this cycle degree of exchanging entity has been done dynamic rising and has been regulated, therefore will be with up-to-date each scheduling entity of Channel Elements quantity allotted information notification of once distributing of this cycle for each scheduling entity, can send the described Channel Elements quantity allotted information that obtains according to the Channel Elements quantity allotted information and the original allocation quantity in the Channel Elements rising quantity information of described scheduling entity correspondence, last cycle, i.e. determined number in the step 304 for the scheduling entity of regulating particularly to dynamically rising; The scheduling entity of regulating to dynamically not rising sends the Channel Elements quantity allotted information identical with the Channel Elements quantity allotted information in last cycle.

The Channel Elements quantity allotted of scheduling entity dynamically rises to regulate can also several different methods, for example can select one or several

Less scheduling entity rises CE etc.

In the channel unit distribution method that present embodiment provides; all users' actual use Channel Elements quantity information surpasses the default Channel Elements licensed number information in base station and satisfies and carry out the Channel Elements quantity allotted when dynamically rising the condition of regulating in the base station; select CE quantity allotted and the dynamic object that rises and regulate of the inconsistent scheduling entity conduct of original allocation quantity in the last cycle; and the Channel Elements quantity allotted after will rising is informed the rising object; the Channel Elements quantity allotted of other scheduling entity remains unchanged; the CE number that makes interior all users of current base station system use is limited in the zone of reasonableness of " LICENSE CE " permission, with protection equipment supplier's interests.

Fig. 4 regulates Channel Elements quantity embodiment flow chart for dynamic fairness in the channel unit distribution method of the present invention, and this method comprises as shown in Figure 4:

Step 400 receives the scheduling entity Channel Elements use statistical information that a plurality of scheduling entity send, and gathers;

The actual use CE quantity that scheduling entity is added up all users in this scheduling entity by the cycle is

Scheduling entity can be expressed as for the CE quantity information that the user distributes

Non-service link can be seized CE quantity can be expressed as NonServiceCE _m, select the interior preempting priority of this scheduling entity simultaneously and count PRI _mA highest service link and the seized CE quantity of this service link can be expressed as ServiceCE _m, use statistical information to report base station system as the scheduling entity Channel Elements in the lump, base station system gathers each scheduling entity reported data:

A, obtain first statistical information, promptly calculate the current actual CE of use of all users and count summation according to the described actual Channel Elements quantity information that uses: ${\mathrm{CE}}^{\mathrm{Used}}=\mathrm{\Σ}{\mathrm{CE}}_m^{\mathrm{Used}}(m=1...M);$

The seized CE number of all non-service links in b, the calculation base station:

NonServiceCE _Total=∑ NonServiceCE _m, (m=1...M); The system of station finds that first statistical information had not both exceeded the default thresholding of Channel Elements licensed number information arrival of base station after gathering each scheduling entity reported data, the Channel Elements licensed number information that also is not lower than the base station arrives default thresholding, promptly first statistical information is in the scope of regulating that need not descend or rise, if but the current lifting CE that do not carry out handles, on certain scheduling entity Add User or original user's speed such as increases at the fairness that is difficult under the situation to guarantee between each scheduling entity, the fairness that therefore also needs to carry out between scheduling entity is handled.

Step 401, the scheduling entity Channel Elements that scheduling entity is reported uses the PRI that comprises in the statistical information _mSort;

Select maximum PRI _mBe designated as

If

Greater than 0, then execution in step 402; Otherwise, think to reach the CE stable state, do not carry out fairness and handle.Because this moment

Therefore be not more than 0 and so only equal 0 situation, at the PRI of all scheduling entity _mUnder=0 the situation, can illustrate that CE quantity is distributed in and be in a comparatively fair state between each scheduling entity, can no longer carry out dynamic fairness and regulate.

Step 402, obtain the Channel Elements quantity allotted information in last cycle of the pairing scheduling entity of described preempting priority information peak and described scheduling entity sends in it all users' actual use Channel Elements quantity information between difference, select that the Channel Elements quantity allotted of the scheduling entity of difference minimum is carried out dynamic fairness and regulate;

Calculate

The CE quantity allotted in corresponding last cycle of scheduling entity

With Difference, the scheduling entity of difference minimum is carried out rising CE handles.Can application of formula ${\mathrm{CE}}_m^{\mathrm{License}}=\mathrm{MIN}[{\mathrm{CE}}_m^{\mathrm{Init}},{\mathrm{CE}}_m^{\mathrm{License}\′}+{\mathrm{CE}}_m^{\mathrm{License}\′}*a\%],$ Decimal point rounds up, and guarantees to rise at least 1 CE, the Channel Elements quantity allotted of the scheduling entity of difference minimum is carried out rising CE handle, wherein

Be the Channel Elements quantity allotted information of described scheduling entity correspondence,

Be original allocation quantity,

Be the Channel Elements quantity allotted information in described last cycle of scheduling entity, a% is that fairness is regulated ratio, and a% is that empirical value for example can be 10%.

Step 403 sends the Channel Elements quantity allotted information that corresponding dynamic fairness is regulated gained to each scheduling entity.

Because the Channel Elements quantity allotted information of this cycle degree of exchanging entity has been done dynamic fairness and has been regulated, therefore up-to-date each scheduling entity of Channel Elements quantity allotted information notification of once distributing for each scheduling entity of this cycle can be the Channel Elements quantity allotted information after sending described adjusting to the scheduling entity of carrying out dynamic fairness adjusting particularly; To not carrying out the scheduling entity transmission Channel Elements quantity allotted information identical that dynamic fairness is regulated with the Channel Elements quantity allotted information in last cycle.

Dynamically fairness is regulated can also several different methods, for example CE is fallen in the scheduling entity of difference maximum and handles; Also can select Minimum scheduling entity carries out rising the CE processing, can also select CE processing etc. falls in maximum scheduling entity.

In the channel unit distribution method that present embodiment provides; all users' actual use Channel Elements quantity information is in and does not need dynamically to descend or when dynamically rising the number range of regulating in the base station; in order to guarantee the fairness between each scheduling entity; can select specific scheduling entity to carry out fairness as controlled plant regulates; and the Channel Elements quantity allotted after will regulating is informed controlled plant; the Channel Elements quantity allotted of other scheduling entity remains unchanged; the CE number that makes interior all users of current base station system use is limited in the zone of reasonableness of " LICENSE CE " permission; interests with the protection equipment supplier; can guarantee simultaneously the fairness between different user; differentiation meets benefits of operators.

When adopting dynamic CE dispatching algorithm, change the access principle of HSUPA base station (NodeB), no longer be professional as R99, based on " Min UL channelisation code length " minimal frequency spreading factor, it corresponds to by maximum rate and distributes CE to carry out access, as long as have enough CE resources to guarantee that the minimum CE number that needs of this HSUPA user can carry out the access principle of access but adopt, need access principle and the NodeB of RNC to be consistent so equally, this can use user's access principle indication information to report RNC by NodeB and finish, such as increasing following field and finish by in the audit response message " AUDIT RESPONSE " of NBAP signaling:
