Detailed description of the invention

For making object of the present invention, technological means and advantage clearer, below in conjunction with accompanying drawing to thisInvention is described in further details.

General resource pool is all to adopt resource queue, preferentially uses the strategy of prostatitis resource. For example, currentUsed 10 resources, if front 3 resources discharge, seven resources can once be advanced to so belowQueue front, if need to augment resource time, carry out Resources allocation from tail of the queue. This strategy is at resource poolIn resource send while variation and can cause the variation of other resources in pond, be synchronously bringing and asking between systemTopic.

Basic thought of the present invention is optimized the dynamic assignment of above-mentioned resource pool and adjustment strategy, protectsStay the mechanism of dynamic assignment, abandon the strategy of dynamic adjustment. That is to say, allow all money in resource poolSource all becomes static, and complete deleting of resource by dynamic distribution mechanism and build, and by carrying of having distributedStaticization of ripple, thus ensure that the change of indivedual resources can not have influence on other resource.

In the Base-Band Processing of BBU, all taking carrier antenna (AXC) as minimum unit, soAXC is exactly the least resource in resource pool. At the chain of processing unit, BBP and the BBI of BBPRoad, all processes taking AXC as minimum unit in the transmission link of BBI and RRU or transmits, like thisJust can ensure that AXC processing demands and the ability of etching system is all static when any. Simultaneously by eachAXC element number also adds effective mark, like this when certain carrier resource need to be deleted or set up to systemTime, only need to notify corresponding subsystem (BBP, BBI or RRU) to use the AXC of system assignment. The AXC using due to other original carrier resources does not need to change, so can be to not originalCarrier wave has any impact, thereby has avoided the strict synchronous requirement between subsystem.

Next, by specific embodiment, specific implementation of the present invention is described.

Fig. 2 is the particular flow sheet of dynamic resource pond management method in the present invention. The method can be at Fig. 3In shown dynamic resource management system, implement. Method flow shown in Fig. 2 is with the data place to carrier wave iReason describes for example. In actual applications, need to carry out identical processing to all carrier waves. As Fig. 2Shown in Fig. 3, concrete management method comprises:

Step 201 is when newly-built carrier wave i, relevant to carrier wave i with foundation in RRU at BBP, BBICorresponding relation.

Particularly, first, be the AXC allocation identification in system. Interface profit between BBP and BBICarrying data with AXC, on the each Ir light mouth between BBI and RRU, is also to carry by AXCData. Wherein, the AXC between the AXC between BBP and BBI and BBI and RRU is separate,And, between BBI and RRU, between the AXC of different I r light mouth, be also separate, therefore carrying outWhen AXC mark, can be by carrying out distinguishing identifier between each AXC between BBP and BBI, by BBIAnd between each AXC of same Ir light mouth, carry out distinguishing identifier between RRU.

Then,, in the time of a newly-built carrier wave, set up following corresponding relation: in BBP, set up carrier wave iAnd point be used in the corresponding relation between each AXC of this carrier wave of carrying i data. As previously mentioned, AXCFor the least resource of resource pool in BBP, therefore, common point of AXC that is used in carrying one carrier wave is manyIndividual, so just at carrier wave i with set up the relation of one-to-many between for the multiple AXC that carry, for example, useBe AXC0～7 in the AXC of bearing carrier wave i, the corresponding relation of setting up is: carrier wave i corresponding A XC0～7;Certainly,, if the carrier occupancy resource of setting up is very little, also can only distribute 1 AXC, for carrying thisThe data of carrier wave, now, carrier wave i and what set up for the single carrier wave carrying is exactly man-to-man relation.

In BBI, each AXC for bearing carrier wave i data and and RRU between foundation and BBPCorresponding relation in the Ir light mouth A of interface between part or all of AXC. Between concrete and BBP for carryingThe different AXC of can the be corresponding one or more Ir light mouths of each AXC of i data, for example, build in BBIAXC0～7 of vertical AXC0～7 corresponding Ir light mouth 1 and/or AXC0～7 of Ir light mouth 2, as Fig. 4 instituteShow. In the time of specific implementation, in BBI, can be for example, by memory cell (RAM) wherein by everyIndividual BBU AXC data after treatment store, the corresponding fixing storage of each AXC markAddress, certain AXC of the corresponding Ir light mouth of this memory address.

In RRU, set up the part or all of AXC of Ir light mouth A and the corresponding relation of carrier wave i. LogicalCross the foundation of above-mentioned three groups of corresponding relations, make the carrier wave i data in BBP finally correspond to RRUCarrier wave i on. For example, in BBP, set up carrier wave i corresponding A XC0～7, in BBI, set up AXC0～7AXC0～7 of corresponding Ir light mouth 1, set up the corresponding carrier wave i in AXC0～7 of Ir light mouth 1 in RRU.

The foundation of above-mentioned corresponding relation, does not need one to fix on same radio frames and complete, to BBP, BBIDo not require strict synchronous with RRU.

Step 202, at carrier wave i duration of existence, in BBP, BBI and RRU, preserve with carrier wave i phaseThe corresponding relation closing remains unchanged, and carries out the transfer of data of carrier wave i according to the corresponding relation of this foundation.

The corresponding relation of setting up by step 201, corresponding AXC and the chain of carrier wave just having distributedRoad becomes static state. Particularly, on down direction, BBP passes the data of carrier wave i by AXC0～7Be defeated by BBI, BBI, according to the corresponding relation of setting up, is placed on Ir light mouth by the data that are received from AXC0～7On 1 AXC0～7, be transferred to RRU, RRU reflects AXC0～7 data that receive on Ir light mouth 1Be mapped to carrier wave i upper, send; On up direction, RRU passes through the data of the carrier wave i of receptionAXC0～7 of Ir light mouth 1 are transferred to BBI, and BBI passes through the data of AXC0～7 on Ir light mouth 1And AXC0～7 between BBP are transferred to BBP, BBP receives the data of AXC0～7, can determineBelong to the data of carrier wave i. In whole processing procedure, BBP, BBI and RRU are all according to AXC'sMaximum processing capability is processed, and the AXC that no matter is assigned with and takies is for how many, in transmission dataDuring with processing, all the AXC of all marks is processed. For example, suppose the manageable AXC of systemBe 200, even if the AXC being assigned with only has 50, also can process together 200 AXC.

Can distribute to other carrier waves for carrier resource deleted in guarantee system and use, preferably, enterOne step comprises following processing:

Step 203, while deleting carrier wave i, BBP, BBI with in RRU by relevant to carrier wave i rightShould be related to deletion.

The processing of this step for deleting carrier wave, while deleting carrier wave, in BBP, BBI and RRUDeletion action does not require in same radio frames and completes, and for the carrier wave of deleting, does not require BBP, BBIStrict synchronous with RRU. For example, and deleted carrier resource (AXC0～7) can also basisNeed to be distributed to arbitrarily other newly-built carrier waves, thereby be realized can joining flexibly of vacant resource.

So far, the method flow in the present embodiment completes. After processing by the way, for distributingEach carrier wave, the resource that it is corresponding and transmission link are all static; Therefore, when a certain carrier wave is set upOr while deleting, resource and transmission link that other carrier waves are corresponding remain unchanged, also just can not be to other carrier wavesImpact.

For a simple example, suppose that original carrier wave is C0, C1, C2, if leave out C1 carrier wave, andAnd RRU has deleted the relevant corresponding relation of C1 carrier wave in radio frames k, even in this radio frames kBBP has been synchronizeed the deletion of carrier wave i and corresponding relation thereof with BBI, because C0 and two carrier waves of C2 existBBP processing unit and BBP do not change to the AXC position in the transmission link of BBI, soC0 and C2 can not be affected, and affected is only C1, and builds carrier wave C1 owing to deletingDelete that to build be exactly not need guarantee business stable originally, so adopt this MECHANISM SOLUTION except right between systemIn synchronous strict demand.

By the processing of the invention described above, make dynamic resource pool technology ensure to have joined in pond the phase of resourceCan join flexibly static and vacant resource, thereby can avoid the variation of certain resource in resource pool, (carrier wave is deletedBuild) cause other resources (carrier wave) in pond are exerted an influence, ensure resource distribution and the seamless company that uses sideConnect.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all at thisWithin the spirit and principle of invention, any amendment of making, be equal to replacement, improvement etc., all should be included inWithin the scope of protection of the invention.
