Background technology
TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, the CDMA (Code Division Multiple Access) that time-division is synchronous) adopts OVSF (Orthogonal Variable Spreading Factorcodes, orthogonal variable frequency extension factor code) spreading code, wherein, TD-SCDMA is as the 3G (Third Generation) Moblie standard, with smart antenna, synchronization CDMA (Code Division Multiple Access, code division multiple access) and technology such as software radio be melted in TD-SCDMA, the advantage of TD-SCDMA comprises availability of frequency spectrum height, business support had flexibility, frequency flexibility etc.
Concrete, TD-SCDMA is owing to adopt the OVSF spreading code, thereby the spreading code that guarantees different spreading factors on same time slot is a quadrature, and the effect of OVSF spreading code is the different terminals user who is used for distinguishing in the same time slot, promptly by using the OVSF spreading code to guarantee the orthogonality of down link different terminals subscriber channel or same terminal use's different business channel, can adapt to the requirement of multiple business, the definition mode of a kind of OVSF spreading code as shown in Figure 1, this mode defines the OVSF spreading code for the mode that adopts code tree.When a specific channel code is assigned to a terminal use, this terminal use can use the channel resource of this channel code correspondence, simultaneously, because between the different channels sign indicating number is quadrature, therefore by distributing different channel code to give different terminal uses, make between the terminal use and just can distinguish.
From the code tree of Fig. 1 as can be seen, each of code tree grade has all defined the sign indicating number resource of spreading factor SF, wherein, the size of channel code is the size of spreading factor, this spreading factor SF has determined the bandwidth of the channel resource that the terminal use can use, i.e. what of terminal use's data volume that can send in the unit interval.Wherein, each yard resource all has a requirement in use, promptly when a sign indicating number adopts in a time slot, then sign indicating number resource and the sign indicating number resource on the subordinate code tree path (above-mentioned two kinds of sign indicating numbers are the sign indicating number that gets clogged) fastened of his father just can not be used in same time slot, promptly the number of a spendable sign indicating number of time slot is unfixed, relevant with the data rate and the spreading factor of each physical channel, in the TD-SCDMA system, available spreading factor SF scope is 1～16.For example, when SF selected 4, available sign indicating number resource was C 4,1, C 4,2, C 4,3, C 4,4, C 2,1, C 2,2, C 1,1, when the terminal use has taken C 4,1Resource the time, the sign indicating number resource (C on the paternal line 2,1And C 1,1) can not in same time slot, adopt, same, when SF selected 8, the terminal use had taken C 4,1Resource the time, C 8,1And C 8,2Can not in same time slot, adopt, wherein, when SF is 4, C 4,1, C 4,2, C 4,3, C 4,4Can abbreviate C as 4
In the prior art, for distribution and the service efficiency that improves yard resource, under the situation that satisfies terminal use's demand, need make the terminal use take still less sign indicating number resource as far as possible, avoid the generation of yard fragment, under the enough situation of systematic code resource, take into full account terminal use's Capability Requirement, satisfy terminal use's QoS (Quality of Service as far as possible, service quality), make the sign indicating number resource have higher execution efficient.Wherein, in assigning process, reduce the generation of sign indicating number fragment as far as possible, avoiding under the enough situation of sub-district or carrier wave total resources (promptly can satisfy terminal use's demand), but the situation that the terminal use can't insert.
In realizing process of the present invention, the inventor finds to exist at least in the prior art following problem:
The specific implementation of code resource management is not taken all factors into consideration in the prior art, there is not assigned code resource efficiently, when using different distribution method to solve different problems, the implementation procedure complexity, execution efficient is low, in case when new demand is arranged then need to revise allocation strategy, various distribution methods are not integrated consideration.And the resource consolidation process of handling at the sign indicating number fragment in the prior art carries out and can influence systematic function, do not provide factors such as concrete implementation method and triggering opportunity.

Provide a kind of method for managing resource under a kind of application scenarios of the present invention, this method is applicable in the TD-SCDMA system, adopting wireless code (is that example describes with OVSF resource sign indicating number) is that UE provides a yard resource, when yard resource is provided for UE, can use single time slot to provide a yard resource, also can use a plurality of time slots to provide a yard resource, wherein as UE as UE, (for example, 3 C of UE service needed when the surplus resources of single time slot satisfies the professional required sign indicating number resource of UE 4, and C in the single time slot 4,1, C 4, 2, C 4,3, C 4,4When all not using, 4 C are arranged then 4, satisfy the professional required sign indicating number resource of UE), selecting single time slot is described user equipment allocation resource; (for example, 3 C of UE service needed when the surplus resources of single time slot does not satisfy the professional required sign indicating number resource of UE 4, and C in the single time slot 4,1, C 4,2When not using, then have only 2 C 4, can not satisfy the professional required sign indicating number resource of UE), at this moment, needing to select a plurality of time slots is that described user equipment allocation resource (for example, is selected C from above-mentioned time slot 4,1And C 4,2, and from the another one time slot, select a C 4), in the present embodiment with by using single time slot to provide a yard resource to describe as example as UE.
Among the present invention, when yard resource is provided for UE, also need to consider Midamble sign indicating number (training sequence), this Midamble is used for channel estimating, power control, adjustment synchronously etc., the method of salary distribution of Midamble sign indicating number comprises Default (acquiescence) method of salary distribution, Common (public) method of salary distribution and the specific method of salary distribution, be that example describes with the Default method of salary distribution among the present invention, this public distributing mode and the specific method of salary distribution are other methods of salary distribution.When the Midamble sign indicating number adopted the Default method of salary distribution, the Key value of Midamble sign indicating number had different spans, and promptly K=(2,4,6,8,10,12,14,16), at the different values of Key, the code tree of OVSF is divided into K group, channelizing code character (for example, above-mentioned C 4,1) independent Midamble sign indicating number of use, promptly all channel codes in channelizing code character can only be assigned to same terminal use, wherein, the corresponding relation of this channelizing code character and independent Midamble sign indicating number will describe in detail in the following description, not repeat them here.
As shown in Figure 3, this method for managing resource may further comprise the steps:
Step S301, UE sends service request to RNC.
Wherein, the type of service of carrying in this service request (for example comprises the transplantation type business, note, USSD (Unstructured Supplementary Service Data, non-structural supplementary data), CRBT, intelligent network etc.), enhanced services (for example, WAP (Wireless Application Protocol, WAP (wireless application protocol)), multimedia message, Java downloads, get online without being tethered to a cable etc.), difference type business (for example, video telephone, streaming media service), characteristic type business (for example, single base station location technology of utilizing smart antenna to realize, PoC (Push to talk on Cellular, Cellular Networks Push-to-Talk) etc.).Certainly, type of service is not limited to above-mentioned mode classification, also is not limited to above-mentioned business, does not repeat them here.
Among the present invention, the information of carrying in this service request (information of service request) includes but not limited to: the request directional information of service request (for example, being up service request or descending service request); The resource information of service request (for example, requested resource is the ovsf code resource); SF information when the resource of service request is the ovsf code resource (for example, SF be 4 or 8 etc.); Resource quantity information (for example, 3 C of service needed that service request is required 4, promptly in ovsf code resource tree shown in Figure 1, needing SF is 3 ovsf code resources of 4, from C 4,1, C 4,2, C 4,3, C 4,4Middle 3 of selecting wherein); The allocation model information of the Midamble sign indicating number of service request (for example, Default mode); Midamble Key value information when described Midamble sign indicating number allocation model is Default (for example, K is 4, or 8).
Step S302, whether RNC is this UE assigned code resource according to this service request judgement.Wherein, this yard resource is the ovsf code resource.
Need to prove that sign indicating number resource judging process is the only way which must be passed that each UE inserts, promptly each UE (needs to use the ovsf code resource) when inserting, RNC all needs the business of this UE is adjudicated, have only after adjudicating successfully, just allow this UE to insert, be this UE and distribute the ovsf code resource.
Wherein, RNC process that this service request is adjudicated is specially:
RNC obtains the required resource information of described service request according to this service request, for example, the required resource quantity information of service request in the information of carrying in the above-mentioned service request is that to need SF be 3 ovsf code resources of 4, and then the required resource information of this service request is 3 ovsf code resources (SF is 4); Resource information in the sub-district that this RNC is controlled by the required resource information of service request relatively and this RNC; When having enough resource allocations to give this service request in the sub-district, RNC need provide the ovsf code resource for this UE.For example, have in the time slot untapped ovsf code resource surpass 3 ovsf code resources (SF is 4) in the sub-district that RNC controlled, then RNC is this UE distribution ovsf code resource by using this time slot.
Step S303, when needs distributed the ovsf code resource for UE, RNC obtained the optimum method of salary distribution according to the information inquiry policy library of this service request.
The court verdict of RNC is for distributing the ovsf code resource for UE, and RNC takes all factors into consideration the information of service request by the query strategy storehouse, obtains the optimum method of salary distribution from policy library.Wherein, pre-configured plurality of distribution mode in policy library, it is that UE distributes the ovsf code resource that RNC selects one or more methods of salary distribution wherein according to the actual needs.Concrete, the pre-configured method of salary distribution includes but not limited to the historical method of salary distribution, order and/or the inverted order method of salary distribution, the compact method of salary distribution in policy library.
Need to prove, policy library is the set that the corresponding method of salary distribution is provided for various different demands, and OVSF resource sign indicating number has the characteristics of self, can dispose the method for salary distribution according to OVSF resource sign indicating number own characteristic in advance at policy library, be the above-mentioned historical method of salary distribution, order and/or the inverted order method of salary distribution, the compact method of salary distribution etc., and the explanation of OVSF resource sign indicating number own characteristic will be described in detail in the process below, do not repeat them here.
Among the present invention, when distributing the ovsf code resource, need take all factors into consideration the requesting party to information such as the allocation model of ovsf code resource, the SF information of, request, Midamble sign indicating number, Midamble Key values, inquire about this policy library, to consider that in minute timing the requesting party is to being that example describes, when the requesting party when being down direction, select the historical method of salary distribution to be the optimum method of salary distribution; Or when the requesting party when being up direction, the selected compact method of salary distribution is the optimum method of salary distribution.Certainly; can not guarantee only to use a kind of method of salary distribution to finish all ovsf code resource allocations; promptly need to select according to the actual needs one or more methods of salary distribution; when taking all factors into consideration the information of service request; be not limited to only consider the requesting party to; among the present invention with the requesting party to being that example describes, the method for all Information Selection methods of salary distribution by using above-mentioned service request all within protection range of the present invention, does not repeat them here.
Concrete, for down direction, in agreement, specified the ovsf code that only uses SF=16, or the ovsf code of SF=1, promptly the characteristics according to this ovsf code can be chosen in the historical method of salary distribution of main employing on the down direction, make the utilance of OVSF resource sign indicating number the highest.For example, for the same number of OVSF resource of needs code requirement, at the value of different Midamble Key, resource is maximum to be utilized but the flexible configuration strategy is to reach, and wherein, has stipulated Midamble sign indicating number and channelizing code character (above-mentioned OVSF resource sign indicating number under the Default mode in agreement, for example, C 4,1, C 4,2, C 4,3, C 4,4) between corresponding relation, this corresponding relation does not repeat them here, and for convenience of description, only describes accordingly when in use.For example, if the code channel of 5 SF=16 of demand, to the time slot of Midamble Key=6, the Midamble sign indicating number is that example describes with m, is specially C at the Midamble sign indicating number of agreement regulation and the corresponding relation of channelizing code character 16,1Corresponding m 1, C 16,2Corresponding m 1, C 16,3Corresponding m 2, C 16,4Corresponding m 2, C 16,5Corresponding m 3, C 16,6Corresponding m 3, C 16,7Corresponding m 4, C 16,8Corresponding m 4, C 16,9Corresponding m 5, C 16,10Corresponding m 5, C 16,11Corresponding m 5, C 16,12Corresponding m 5, C 16,13Corresponding m 6, C 16,14Corresponding m 6, C 16,15Corresponding m 6, C 16,16Corresponding m 6, in the process that reality is used, each Midamble sign indicating number can only be distributed to a UE, for example, and when UE uses C 16,1The time, then be equivalent to m 1Be used, i.e. C 16,2Can not use distributing to other UE.In summary it can be seen, in order to save resource, (C on second code tree of SF=2 16,9To C 16,16) select 4 code channel (C with historical principle 16,9To C 16,12Or C 16,13To C 16,16), again with first branch (C of historical principle at SF=2 16,1To C 16,8) select 1 code channel, make that the OVSF resource of using is minimum.And, be specially C at the Midamble sign indicating number of agreement regulation and the corresponding relation of channelizing code character for the time slot of Midamble Key=8 16,1Corresponding m 1, C 16,2Corresponding m 1, C 16,3Corresponding m 2, C 16,4Corresponding m 2, C 16,5Corresponding m 3, C 16,6Corresponding m 3, C 16,7Corresponding m 4, C 16,8Corresponding m 4, C 16,9Corresponding m 5, C 16,10Corresponding m 5, C 16, 11Corresponding m 6, C 16,12Corresponding m 6, C 16,13Corresponding m 7, C 16,14Corresponding m 7, C 16,15Corresponding m 8, C 16,16Corresponding m 8, as can be seen, can be directly on the whole code tree of SF=1 (C 16,1To C 16,16) 5 code channels of the historical principle selection of use (need to use two to form right OVSF resource, for example, C 16,1And C 16,2For a pair of).Wherein, use historical principle to select the process of code channel to describe in detail in the step below, do not repeat them here.
For up direction, having specified in agreement and can having used SF is 1 to SF to be 16 spreading code, can be chosen in up direction according to the characteristics of this ovsf code and mainly adopt the compact method of salary distribution, makes the utilance of OVSF resource sign indicating number the highest.For the code requirement that needs different types of SF simultaneously, at the value of different MidambleKey, resource is maximum to be utilized but the flexible configuration strategy is to reach.Wherein, this uses the compact method of salary distribution to select the process of code channel to describe in detail in the step below, does not repeat them here.
Need to prove, only be the collocation method that has provided a kind of policy library for example more than, can need any selection in actual applications, three kinds of methods of salary distribution can be disposed neatly, to reach the peak use rate of yard resource.
Step S304, RNC distributes the ovsf code resource according to this optimum method of salary distribution for this UE.
When the method for salary distribution of optimum is the order and/or the inverted order method of salary distribution, this RNC in resources bank in order or the mode of inverted order select spendable resource; Be specially: when the Midamble sign indicating number adopted the Default method of salary distribution, RNC was according to the value of different K ey in the described Midamble sign indicating number, and the mode of selecting sequence or inverted order is described user equipment allocation resource; When the Midamble sign indicating number adopted other methods of salary distribution, the mode of RNC selecting sequence was described user equipment allocation ovsf code resource, and for the Midamble sign indicating number under other method of salary distribution, then specified the Midamble sign indicating number of an idle mode to give UE by high level.
Concrete, radio network controller is according to the value of different K ey in the described Midamble sign indicating number, the mode of selecting sequence or inverted order is that described user equipment allocation resource specifically comprises: the value of Key is 2,4,8,16 o'clock in the described Midamble sign indicating number, and n RU all adopts the order assignment mode; Wherein, described RU is unit resource (for example, C 16,1Be a RU), described n is the quantity of RU; The value of Key is 10,12,14 o'clock in the described Midamble sign indicating number, adopts the order assignment mode to distribute m1 RU, adopts the inverted order method of salary distribution to distribute remaining (n-m1) individual RU; Wherein, m1 is the numerical value of n mould 2; The value of Key is 6 o'clock in the described Midamble sign indicating number, adopts the order assignment mode to distribute m2 RU, adopts the inverted order method of salary distribution to distribute remaining (n-m2) individual RU; Wherein, m2 is the numerical value of n mould 4.
Owing in agreement, stipulated the corresponding relation between the Midamble sign indicating number and channelizing code character under the Default mode, obtained the value of different K ey in the above-mentioned Midamble sign indicating number according to the corresponding corresponding relation of regulation in the agreement, the mode of selecting sequence or inverted order is the concrete condition of UE Resources allocation, with Key=6 is that example describes, and needs the code channel of a SF=16, as can be known, n is 5, m2 is 5 moulds 4, and promptly m2 is 1, and n-m2 is 4.Known the corresponding relation of Midamble sign indicating number and channelizing code character in the superincumbent description, adopted the order assignment mode to distribute m2 RU, promptly adopted the order assignment mode to distribute 1 RU, when all channelizing code characters are when being used selection C 16,1Be a RU; Adopt the inverted order method of salary distribution to distribute remaining (n-m2) individual RU, promptly adopt the inverted order method of salary distribution to distribute 4 RU, promptly select C 16,16, C 16,15, C 16,14, C 16, 13, from top corresponding relation as can be seen, C 16,16, C 16,15, C 16,14, C 16,13All corresponding same m 6, in summary it can be seen that above-mentioned distribution method is optimum distribution method, the resource that takies is minimum.
Wherein, the process flow process as shown in Figure 4 in the time of should carrying out resource allocation by the use order and/or the inverted order method of salary distribution does not repeat them here.
When the method for salary distribution of optimum was the historical method of salary distribution, this RNC was by searching the historical record of this UE in time slot, and preferentially to use the OVSF resource in this historical record be that this UE distributes the OVSF resource.Wherein, this historical record comprises: the historical resource that this UE is shared; (for example, the historical resource that takies of UE is C to the occupied obstruction resource of the shared historical resource of this UE 16,1The time, then corresponding occupied obstruction resource is C 8,1, C 4,1, C 2,1Deng); Described subscriber equipment took all resources of resource place resource group (for example, the historical resource that takies of UE is C when the Midamble sign indicating number adopted the Default method of salary distribution 16,1The time, corresponding Midamble sign indicating number is m1, then all resources of place resource group are historical record) etc.When the historical method of salary distribution can not be finished the distribution of ovsf code resource of whole UE or UE and not have corresponding historical record, can also the employing order and/or the inverted order method of salary distribution finish the distribution of remainder.
Wherein, process flow process as shown in Figure 5 that should be when using the historical method of salary distribution and binding sequence and/or the inverted order method of salary distribution to carry out resource allocation does not repeat them here.
When the method for salary distribution of optimum was the compact method of salary distribution, RNC was by searching the surplus resources in the resources bank; In resources bank, seek the resource that satisfies the UE demand on few one of surplus resources; And preferentially use the resource on few one of surplus resources to be the UE Resources allocation.
Concrete, RNC preferentially seeks satisfactory sign indicating number on fewer one of residue code resource, make the sign indicating number that has distributed concentrate on one so as far as possible, and the number of available codes is maximum on the whole code tree.When two stalks tree all can not satisfy the demands, then be regardless of subtree, the historical method of salary distribution of unified employing.If it is identical and can both satisfy the demands that two stalks are set compact degree, preferentially choose that this UE historical record is arranged.
Wherein, process flow process as shown in Figure 6 that should be when using the compact method of salary distribution and carrying out resource allocation in conjunction with the historical method of salary distribution does not repeat them here.
Among the present invention, RNC can also use the combination in any of three kinds of methods of salary distribution according to preset strategy, specifically comprise: when using the compact method of salary distribution, two resources that all can not satisfy described subscriber equipment demand of resources bank, RNC is by using the historical method of salary distribution to be the UE Resources allocation; Or the identical and equal resource that can satisfy the UE demand of two compact degree of resources bank, the preferential resource of using on subscriber equipment historical record of RNC;
When using the historical method of salary distribution, can not finish all resource allocations of UE when the historical method of salary distribution, the surplus resources that RNC finishes UE by the use order and/or the inverted order method of salary distribution distributes; Or UE do not have historical record, and RNC finishes the resource allocation of UE by the use order and/or the inverted order method of salary distribution.
Certainly, the combination among the present invention is not limited thereto, and the mode of all any combinations is all within protection scope of the present invention.
Among the present invention, when using the optimum allocation mode can't finish all resource requirement of described subscriber equipment, RNC can carry out equivalent resources and distribute, with the resource requirement equivalence of UE on a plurality of resources with same effect.For example, the resource requirement as UE is to need 3 C 8The time, and using the optimum allocation mode to carry out the branch timing, can only distribute 2 C 8, at this moment, can be with 2 C 16Equivalence 1 C wherein 8Thereby, finish the assigning process of resource, be about to resource requirement (1 above-mentioned C of UE 8) equivalence is to (2 above-mentioned C on a plurality of resources with same effect 16).
Step S305, UE realizes corresponding business according to the ovsf code resource information of this distribution.
After RNC distributes the ovsf code resource to finish for this UE, this ovsf code resource information can be sent to this UE, promptly this UE can use this ovsf code resource to realize corresponding business, and for example, RNC is C for this UE distributes the ovsf code resource 8,1And C 4,1The time, when the business of this UE was MMS, promptly UE was by using C 8,1And C 4,1Realize corresponding MMS.
Step S306, UE discharge this ovsf code resource information, and trigger the process of carrying out defragmentation, to improve professional access success rate.
When UE no longer needs to use this ovsf code resource information, discharge this ovsf code resource, for example, when the MMS of UE finishes, UE will discharge corresponding ovsf code resource (C 8,1And C 4,1), this ovsf code resource can continue as other business (business of this terminal or the business of other-end) and use.
Need to prove that the purpose of resource consolidation is in order to put the ovsf code resource fragmentation in order, thereby improve big professional access success rate, avoid because the entire system resource enough but because the sign indicating number fragment too much causes the failure of service access.In addition, resource consolidation process waste system carries out efficient, and can influence systematic function, startup resource consolidation process that promptly will be few as far as possible, but can finish defragmentation, carry out fragment when discharging the ovsf code resource among the present invention, effectively realized, but can finish the process of defragmentation at the startup integration process of trying one's best few at UE.
Among the present invention, when the surplus resources of single time slot can't satisfy the required resource of service request, it was the UE Resources allocation that RNC selects a plurality of time slots according to the ability of UE; The ability of this UE comprises the ability in single UL time slot support dicode road of striding time slot ability, UE of UE.At down direction, when the surplus resources of single time slot is not enough to satisfy the demand of UE, may be thought of as the resource that UE distributes a plurality of time slots, for example, two time slots provide 4 RU and 6 RU respectively, satisfy 10 required RU of UE; At up direction, also may be thought of as the demand that resource that UE distributes a plurality of time slots satisfies the surplus resources deficiency of user's single time slot, for example, two time slots provide 2 RU and 8 RU respectively, satisfy 10 required BRU of UE.In addition,, can not have the code channel of demand configuration yet, for example, satisfy 1 required SF8 of UE with 2 SF 16 by distributing different SF to satisfy at same time slot.Promptly when inserting, big speed is not subjected to the restriction of fragment, as long as the available RU in the carrier wave satisfies the demands (even RU is dispersed in the different time-gap), and satisfy user's demand (promptly pay the utmost attention to maximum rate, have only when maximum rate is admitted failure, just will consider the reduction of speed access) as far as possible.
Need to prove that it is the UE Resources allocation that RNC selects single time slot, or RNC to select a plurality of time slots be the UE Resources allocation, when being the UE Resources allocation in each time slot, all can use above-mentioned resource management flow process as the UE Resources allocation, do not repeat them here.
Wherein, the inventive method can be adjusted each sequence of steps according to actual needs.
Process when the use order as shown in Figure 4 and/or the inverted order method of salary distribution are carried out resource allocation may further comprise the steps:
Step S401, RNC judge whether the Midamble sign indicating number adopts the Default method of salary distribution, when judged result when being, forward step S403 to, otherwise, forward step S402 to.Among the present invention, be 16 to describe with spreading factor SF.
Step S402, the method for salary distribution of RNC selecting sequence is the UE Resources allocation.
Need to prove, when the Midamble sign indicating number adopts other methods of salary distribution, the mode of RNC selecting sequence is described user equipment allocation ovsf code resource, and for the Midamble sign indicating number under other method of salary distribution, then specifies the Midamble sign indicating number of an idle mode to give UE by high level.
Step S403, RNC obtain the value of Key under the Default method of salary distribution, when the value of this Key is 6, forward step S404 to, when the value of this Key is, forward step S402 at 2,4,8,16 o'clock, when the value of this Key is, forward step S405 at 10,12,14 o'clock.
Step S404, RNC adopt the order assignment mode to distribute m2 RU, adopt the inverted order method of salary distribution to distribute remaining (n-m2) individual RU; Wherein, m2 is the numerical value of n mould 4.
Step S405, RNC adopt the order assignment mode to distribute m1 RU, adopt the inverted order method of salary distribution to distribute remaining (n-m1) individual RU; Wherein, m1 is the numerical value of n mould 2.
Process when the historical method of salary distribution of use as shown in Figure 5 and binding sequence and/or the inverted order method of salary distribution are carried out resource allocation may further comprise the steps:
Step S501, RNC search the historical record of this UE in time slot, and preferentially use the OVSF resource in this historical record to distribute the OVSF resource for this UE.Wherein, this historical record comprises: the historical resource that this UE is shared; The occupied obstruction resource of the shared historical resource of this UE; Described subscriber equipment took all resources of resource place resource group etc. when the Midamble sign indicating number adopted the Default method of salary distribution.
Step S502, RNC judge whether to finish the distribution of the ovsf code resource of whole UE, when judged result for not the time, forward step S503 to.
Step S503, the RNC employing order and/or the inverted order method of salary distribution are carried out the ovsf code resource allocation for this UE.Wherein, the flow process that this is assigned as between the above-mentioned step S401-step S405 does not repeat them here.
Process when the compact method of salary distribution of use as shown in Figure 6 and the historical method of salary distribution are carried out resource allocation may further comprise the steps:
Step S601, RNC obtain the number of the available ovsf code of two stalks tree respectively.
Step S602, RNC judge whether the situation of two stalks tree is that first stalk tree can meet the demands, and second can not meet the demands.When judged result when being, forward step S603 to, otherwise, forward step S604 to.
Step S603, RNC distributes with compact way on first stalk tree.
Step S604, RNC judge whether the situation of two stalks tree is that second stalk tree can meet the demands, and first can not meet the demands.When judged result when being, forward step S605 to, otherwise, forward step S606 to.
Step S605, RNC distributes with compact way on second stalk tree.
Step S606, RNC judge whether the situation of two stalks trees is whether two stalks tree can both meet the demands, when judged result when being, forward step S608 to, otherwise, forward step S607 to.
Step S607, RNC is regardless of subtree, and unification distributes by historical mode.
Step S608, RNC judge two stalks tree residue code resource situation, when first stalk is set the residue code resource more after a little while, forward step S609 to, set the residue code resource more after a little while, forward step S610 to when second stalk, when two stalks tree residue code resource is identical, forward step S611 to.
Step S609, RNC distributes with compact way on first stalk tree.
Step S610, RNC distributes with compact way on second stalk tree.
Step S611, RNC chooses subtree with historical principle.
Step S612, RNC distributes with compact way on selected subtree.
