2,1, C
2,2, C
1,1, when terminal use has taken C
4,1resource time, the code resource (C in paternal line
2,1and C
1,1) can not in same time slot, adopt, same, when SF selects 8, terminal use has taken C
4,1resource 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 be referred to as C

In 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, the resource of request is ovsf code resource); SF information when the resource of service request is 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, in the ovsf code resource tree shown in Fig. 1, needing SF is 3 ovsf code resources of 4, from C
4,1, C
4,2, C
4,3, C
4,4wherein 3 of middle selection); The allocation model information of the Midamble code of service request (for example, Default mode); Midamble Key value information when described Midamble code 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 of resource is ovsf code resource.
It should be noted that, code resource judging process is the only way which must be passed of each UE access, and each UE is when access (need to use ovsf code resource), RNC all needs the business of this UE to adjudicate, only have after adjudicating successfully, just allow this UE access, be this UE and distribute ovsf code resource.
Wherein, the process that RNC adjudicates this service request 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 above-mentioned service request is that to need SF be 3 ovsf code resources of 4, and the required resource information of this service request is 3 ovsf code resources (SF is 4); Resource information in the community that this RNC controls by the required resource information of comparison service request and this RNC; While having enough resources to distribute to this service request in community, RNC need to provide ovsf code resource for this UE.For example, have untapped ovsf code resource in time slot to surpass 3 ovsf code resources (SF is 4) in the community that RNC controls, RNC is by being used this time slot for this UE distribution ovsf code resource.
Step S303, when needs distribute ovsf code resource for UE, RNC, according to the information inquiry policy library of this service request, obtains the optimum method of salary distribution.
The court verdict of RNC is for distributing ovsf code resource for UE, and RNC, by query strategy storehouse, considers the information of service request, 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 ovsf code resource that RNC selects one or more methods of salary distribution wherein according to the actual needs.Concrete, in policy library, 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.
It should be noted that, policy library is that the set of the corresponding method of salary distribution is provided for various different demands, and OVSF resource code has the feature of self, according to OVSF resource code own characteristic, at policy library, can configure in advance the method for salary distribution, 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 code own characteristic will be described in detail in process below, do not repeat them here.
In the present invention, when distributing ovsf code resource, need to consider requesting party to, ovsf code resource, the SF information of request is, information such as the allocation model of Midamble code, Midamble Key values, inquire about this policy library, take and consider that in minute timing requesting party is to describing as example, when requesting party is when being down direction, selecting the historical method of salary distribution is the optimum method of salary distribution; Or when requesting party is 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 complete all ovsf code resources distributes; need to select according to the actual needs one or more methods of salary distribution; when considering the information of service request; be not limited to only consider requesting party to; in the present invention, take requesting party to describing as example, and the method for all Information Selection methods of salary distribution by the above-mentioned service request of use 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, according to the feature of this ovsf code, can be chosen in the historical method of salary distribution of main employing on down direction, make the utilance of OVSF resource code the highest.For example, for the same number of OVSF resource of needs code requirement, value for different Midamble Key, can to reach resource maximum, utilize by flexible configuration strategy, wherein, in agreement, stipulated Midamble code and channelizing code character under Default mode (above-mentioned OVSF resource code, 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, the time slot to Midamble Key=6, Midamble code be take m as example describes, and at the Midamble code of agreement regulation and the corresponding relation of channelizing code character, is specially C

6, in the process of using in reality, each Midamble code can only be distributed to a UE, for example, and when UE is used C
16,1time, be equivalent to m
1used, i.e. C
16,2can not use distributing to other UE.In summary it can be seen, for saving resource, (C in second code tree of SF=2
16,9to C
16,16) with historical principle, select 4 code channel (C
16,9to C
16,12or C
16,13to C
16,16), then with historical principle SF=2 first branch (C
16,1to C
16,8) select 1 code channel, make the OVSF resource of use minimum.And for the time slot of Midamble Key=8, at the Midamble code of agreement regulation and the corresponding relation of channelizing code character, be specially C

16,1to C
16,16) use historical principle select 5 code channels (need to use the right OVSF resource of two compositions, for example, C
16,1and C
16,2for a pair of).Wherein, use historical principle to select the process of code channel in step, to describe in detail below, do not repeat them here.
For up direction, in agreement, having specified and can having used SF is 1 to SF to be 16 spreading code, can be chosen in up direction mainly adopt the compact method of salary distribution according to the feature of this ovsf code, makes the utilance of OVSF resource code the highest.For the code requirement that needs different types of SF simultaneously, for the value of different MidambleKey, can to reach resource maximum, utilize by flexible configuration strategy.Wherein, this uses the compact method of salary distribution to select the process of code channel in step, to describe in detail below, does not repeat them here.
It should be noted that, be more than only the collocation method that has provided a kind of policy library for example, can need any selection in actual applications, three kinds of methods of salary distribution can be configured neatly, to reach the peak use rate of yard resource.
Step S304, RNC is this UE distribution ovsf code resource according to this optimum method of salary distribution.
When the optimum method of salary distribution is order and/or during 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 Midamble code adopts the Default method of salary distribution, RNC is according to the value of different K ey in described Midamble code, and the mode of selecting sequence or inverted order is described user equipment allocation resource; When Midamble code adopts other methods of salary distribution, the mode of RNC selecting sequence is described user equipment allocation ovsf code resource, and for the Midamble code under other method of salary distribution, by high level, specifies the Midamble code of an idle mode to UE.
Concrete, radio network controller is according to the value of different K ey in described Midamble code, the mode of selecting sequence or inverted order is that described user equipment allocation resource specifically comprises: in described Midamble code, the value of Key is 2,4,8,16 o'clock, and n RU all adopts order-assigned mode; Wherein, described RU is unit resource (for example, C
16,1be a RU), the quantity that described n is RU; In described Midamble code, the value of Key is 10,12,14 o'clock, adopts order-assigned 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; In described Midamble code, the value of Key is 6 o'clock, adopts order-assigned 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 to having stipulated the corresponding relation between Midamble code and channelizing code character under Default mode in agreement, according to stipulating in agreement that corresponding corresponding relation has obtained the value of different K ey in above-mentioned Midamble code, the mode of selecting sequence or inverted order is the concrete condition of UE Resources allocation, take Key=6 as example describes, need the code channel of a SF=16, known, n is 5, m2 is 5 moulds 4, and m2 is that 1, n-m2 is 4.In superincumbent description, know the corresponding relation of Midamble code and channelizing code character, adopted order-assigned mode to distribute m2 RU, adopted order-assigned mode to distribute 1 RU, when all channelizing code characters are by use, selected C
16, 1 is a RU; Adopt the inverted order method of salary distribution to distribute remaining (n-m2) individual RU, adopt the inverted order method of salary distribution to distribute 4 RU, select C
16,16, C
16,15, C
16,14, C
16, 13, from corresponding relation above, can find out C
16,16, C
16,15, C
16,14, C
16,13equal corresponding same m
6, in summary it can be seen, above-mentioned distribution method is optimum distribution method, the resource taking is minimum.
Wherein, should carry out process that resource divides timing flow process as shown in Figure 4 by use order and/or the inverted order method of salary distribution, not repeat them here.
When the optimum method of salary distribution is the historical method of salary distribution, this RNC is 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 OVSF resource.Wherein, this historical record comprises: the historical resource that this UE is shared; (the historical resource that for example, UE takies is C to the occupied obstruction resource of the shared historical resource of this UE
16,1time, corresponding occupied obstruction resource is C
8,1, C
4,1, C
2,1deng); Described in when Midamble code adopts the Default method of salary distribution, subscriber equipment takies all resources of resource place resource group (the historical resource that for example, UE takies is C
16,1time, corresponding Midamble code is m
1, all resources of place resource group are historical record) etc.When the historical method of salary distribution can not complete the distribution of ovsf code resource of whole UE or UE and there is no corresponding historical record, can also employing order and/or the inverted order method of salary distribution complete the distribution of remainder.
Wherein, should, by using the historical method of salary distribution binding sequence and/or the inverted order method of salary distribution to carry out process that resource divides timing flow process as shown in Figure 5, not repeat them here.
When the optimum method of salary distribution is the compact method of salary distribution, RNC is by searching the surplus resources in resources bank; In resources bank, on few one of surplus resources, find the resource that meets UE demand; And preferentially to use the resource on few one of surplus resources be UE Resources allocation.
Concrete, RNC preferentially finds satisfactory code on fewer one of residue code resource, makes like this code having distributed concentrate on one as far as possible, and in whole code tree, the number of available codes is maximum.When two stalk trees all can not satisfy the demands, regardless of subtree, the historical method of salary distribution of unified employing.If it is identical and can satisfy the demands that two stalks are set compact degree, preferentially choose that has this UE historical record.
Wherein, should, by using the compact method of salary distribution and carrying out process that resource divides timing flow process as shown in Figure 6 in conjunction with the historical method of salary distribution, not repeat them here.
In the present invention, RNC can also be used according to preset strategy the combination in any of three kinds of methods of salary distribution, specifically comprise: when using the compact method of salary distribution, two resources that all can not meet described subscriber equipment demand of resources bank, RNC is UE Resources allocation by using the historical method of salary distribution; Or two compact degree of resources bank are identical and the equal resource that can meet UE demand, RNC is preferential uses the resource having on of subscriber equipment historical record;
When using the historical method of salary distribution, all resources that can not complete UE when the historical method of salary distribution are distributed, and the surplus resources that RNC completes UE by use order and/or the inverted order method of salary distribution distributes; Or UE do not have historical record, the resource that RNC completes UE by use order and/or the inverted order method of salary distribution is distributed.
Certainly, the combination in the present invention is not limited to this, and the mode of all any combinations is all within protection scope of the present invention.
In the present invention, when using optimum allocation mode cannot complete all resource requirement of described subscriber equipment, RNC can carry out equivalent resources distribution, by 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
8time, and using optimum allocation mode to divide timing, can only distribute 2 C
8, now, can be with 2 C
16equivalence 1 C wherein
8thereby, complete the assigning process of resource, be about to resource requirement (1 above-mentioned C of UE
8) equivalence is to (2 above-mentioned C in 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 ovsf code resource to complete for this UE, this ovsf code resource information can be sent to this UE, this UE can be used this ovsf code resource to realize corresponding business, and for example, RNC is C for this UE distributes ovsf code resource
8,1and C
4,1time, when the business of this UE is MMS, UE is by being used C
8,1and C
4,1realize corresponding MMS.
Step S306, UE discharges this ovsf code resource information, and triggers the process of carrying out defragmentation, to improve the access success rate of business.
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.
It should be noted that, the object of resource consolidation is in order to arrange ovsf code resource fragmentation, thereby improves the access success rate of large business, avoid because entire system resource enough but because code fragment too much causes the failure of service access.In addition, resource consolidation process waste system execution efficiency, and can affect systematic function, startup resource consolidation process that will be as far as possible few, but can complete defragmentation, in the present invention, carry out fragment when discharging ovsf code resource at UE, effectively realized at the startup integration process of trying one's best few, but can complete the process of defragmentation.
In the present invention, when the surplus resources of single time slot cannot meet the required resource of service request, it is 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 the single UL time slot support dicode road across time slot ability, UE of UE.At down direction, when the surplus resources of single time slot is not enough to meet 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 respectively 4 RU and 6 RU, meet 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 meets the surplus resources deficiency of user's single time slot, for example, two time slots provide respectively 2 RU and 8 RU, meet 10 required BRU of UE.In addition, at same time slot, can by distributing different SF to meet, there is no the code channel of demand configuration yet, for example, with 2 SF16, meet 1 required SF8 of UE.When large speed access, be not subject to the restriction of fragment, as long as the available RU in carrier wave satisfies the demands (even if RU is dispersed in different time-gap), and the demand that as far as possible meets user (is paid the utmost attention to maximum rate, only have when maximum rate is received unsuccessfully, just can consider reduction of speed access).
It should be noted that, it is UE Resources allocation that RNC selects single time slot, or RNC to select a plurality of time slots be UE Resources allocation, while being UE Resources allocation in each time slot, all can use above-mentioned resource management flow process for UE Resources allocation, do not repeat them here.
Wherein, the inventive method can be adjusted each step order according to actual needs.
Use order and/or the inverted order method of salary distribution are as shown in Figure 4 carried out the process that resource is divided timing, comprise the following steps:
Step S401, RNC judges whether Midamble code adopts the Default method of salary distribution, when judgment result is that while being, forwards step S403 to, otherwise, forward step S402 to.In the present invention, the spreading factor SF of take describes as 16.
Step S402, the method for salary distribution of RNC selecting sequence is UE Resources allocation.
It should be noted that, when Midamble code adopts other methods of salary distribution, the mode of RNC selecting sequence is described user equipment allocation ovsf code resource, and for the Midamble code under other method of salary distribution, by high level, specifies the Midamble code of an idle mode to UE.
Step S403, RNC obtains the value of Key under the Default method of salary distribution, when the value of this Key is 6, forwards step S404 to, when the value of this Key is, forwards step S402 at 2,4,8,16 o'clock, when the value of this Key is, forwards step S405 at 10,12,14 o'clock.
Step S404, RNC adopts order-assigned 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.
Step S405, RNC adopts order-assigned 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 historical method of salary distribution of use as shown in Figure 5 binding sequence and/or the inverted order method of salary distribution are carried out the process that resource is divided timing, comprise the following steps:
Step S501, RNC searches the historical record of this UE in time slot, and preferentially to use OVSF resource in this historical record be that this UE distributes OVSF resource.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 in when Midamble code adopts the Default method of salary distribution, subscriber equipment takies all resources of resource place resource group etc.
Step S502, RNC has judged whether the distribution of the ovsf code resource of whole UE, when the determination result is NO, forwards step S503 to.
Step S503, RNC employing order and/or the inverted order method of salary distribution are carried out the distribution of ovsf code resource for this UE.Wherein, the flow process that this is assigned as between above-mentioned step S401-step S405, does not repeat them here.
The compact method of salary distribution of use the historical method of salary distribution are as shown in Figure 6 carried out the process that resource is divided timing, comprise the following steps:
Step S601, RNC obtains respectively the number of the available ovsf code of two stalk trees.
Step S602, RNC judges whether the situation of two stalk trees is that the first stalk tree can meet the demands, and second can not meet the demands.When judgment result is that while being, forward step S603 to, otherwise, forward step S604 to.
Step S603, RNC distributes with compact way on the first stalk tree.
Step S604, RNC judges whether the situation of two stalk trees is that the second stalk tree can meet the demands, and first can not meet the demands.When judgment result is that while being, forward step S605 to, otherwise, forward step S606 to.
Step S605, RNC distributes with compact way on the second stalk tree.
Step S606, RNC judges whether the situation of two stalks trees is whether two stalks trees can meet the demands, and when judgment result is that while being, forwards step S608 to, otherwise, forward step S607 to.
Step S607, RNC is regardless of subtree, and unification distributes by historical mode.
Step S608, RNC judges two stalks trees residue code resource situation, when the first stalk tree residue code resource is when less, forward step S609 to, when the second stalk tree residue code resource is when less, forward step S610 to, when two stalks trees residue code resources are when identical, forward step S611 to.
Step S609, RNC distributes with compact way on the first stalk tree.
Step S610, RNC distributes with compact way on the second stalk tree.
Step S611, RNC chooses subtree with historical principle.
Step S612, RNC distributes with compact way in selected subtree.
