Embodiment
For making purpose of the present invention, technological means and advantage clearer, below in conjunction with accompanying drawing the present invention is described in further details.
General resource pool all is to adopt resource queue, preferentially uses the strategy of prostatitis resource.For example, currently used 10 resources, if preceding 3 resources discharge, seven resources in back can once be advanced to queue front so, when augmenting resource if desired, then come Resources allocation from tail of the queue.The resource of this strategy in resource pool can cause the variation of other resources in the pond when send changing, for bringing problem synchronously between the system.
Basic thought of the present invention is optimized with the adjustment strategy the dynamic assignment of above-mentioned resource pool, keeps the mechanism of dynamic assignment, abandons the strategy of dynamic adjustment.That is to say that it is static to allow all resources in the resource pool all become, finish deleting of resource by dynamic distribution mechanism and build, and staticization of carrier wave that will distribute, thereby guarantee that the change of indivedual resources can not have influence on other resource.
In the Base-Band Processing of BBU, be minimum unit with carrier wave antenna (AXC) all, so AXC is exactly the least resource in the resource pool.At the transmission link of processing unit, BBP and the BBI of BBP, all be that minimum unit is handled or transmitted with AXC in the transmission link of BBI and RRU, so just can guarantee that AXC processing demands and the ability of etching system all is static when any.Simultaneously each AXC element number and adding are effectively identified, when certain carrier resource be deleted or be set up in system need, only need notify corresponding subsystem (BBP, BBI or RRU) to use the AXC of system assignment to get final product like this.Because the AXC that other original carrier resources use does not need to change, thus can not have any impact to original carrier wave, thus avoided strict synchronous requirement between the 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 among the present invention.This method can be implemented in dynamic resource management system shown in Figure 3.Method flow shown in Figure 2 is treated to example with the data to carrier wave i and describes.In actual applications, need carry out identical processing to all carrier waves.As shown in Figures 2 and 3, concrete management method comprises:
Particularly, at first, be the AXC allocation identification in the system.Interface between BBP and BBI utilizes AXC carrying data, on each the Ir light mouth between BBI and RRU, also is by AXC carrying data.Wherein, AXC between the AXC between BBP and BBI and BBI and RRU is separate, and, also be separate between the AXC of different I r light mouth between BBI and RRU, therefore when carrying out the AXC sign, can will carry out distinguishing identifier between each AXC between BBP and BBI, carry out distinguishing identifier between each AXC with same Ir light mouth between BBI and RRU.
Then, when a newly-built carrier wave, set up following corresponding relation: in BBP, set up the corresponding relation between each AXC that carrier wave i and branch be used in this carrier wave of carrying i data.As previously mentioned, AXC is the least resource of resource pool among the BBP, therefore, usually it is a plurality of dividing the AXC that is used in carrying one carrier wave, so just between carrier wave i and a plurality of AXC for carrying, set up the relation of one-to-many, for example, the AXC that is used for bearing carrier wave i is AXC0～7, and then the corresponding relation of Jian Liing 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, be used for the data of this carrier wave of carrying, at this moment, what carrier wave i and the single carrier wave that is used for carrying were set up is exactly man-to-man relation.
In BBI, set up and BBP between each AXC that is used for bearing carrier wave i data and and the part or all of corresponding relation between AXC of the Ir light mouth A of RRU interface.Specifically with BBP between be used for each AXC of carrying i data can the different AXC of corresponding one or more Ir light mouths, for example, set up AXC0～7 of AXC0～7 corresponding Ir light mouth 1 and/or AXC0～7 of Ir light mouth 2 among the BBI, as shown in Figure 4.When specific implementation, in BBI, the AXC data after can each BBU being handled with memory cell (for example RAM) wherein store the corresponding fixing memory address of each AXC sign, 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.By the foundation of above-mentioned three groups of corresponding relations, make that the carrier wave i data in BBP finally correspond on the carrier wave i of RRU.For example, set up carrier wave i corresponding A XC0～7 among the BBP, set up AXC0～7 of AXC0～7 corresponding Ir light mouth 1 among the BBI, set up the corresponding carrier wave i in AXC0～7 of Ir light mouth 1 among the RRU.
The foundation of above-mentioned corresponding relation does not need one to fix on same radio frames and finish, and does not namely require synchronously strict to BBP, BBI and RRU.
By the corresponding relation that step 201 is set up, just AXC and the transmission link of the carrier wave correspondence of having distributed become static state.Particularly, on down direction, BBP is transferred to BBI with the data of carrier wave i by AXC0～7, BBI is according to the corresponding relation of setting up, the data that are received from AXC0～7 are placed on AXC0～7 of Ir light mouth 1 and are transferred to RRU, RRU will be mapped on the carrier wave i, send in AXC0～7 data that Ir light mouth 1 receives; On up direction, RRU is transferred to BBI with the data of the carrier wave i that receives AXC0～7 by Ir light mouth 1, BBI with the data of AXC0～7 on the Ir light mouth 1 by and BBP between AXC0～7 be transferred to BBP, BBP receives the data of AXC0～7, namely can determine to belong to the data of carrier wave i.In the entire process process, BBP, BBI and RRU all handle according to the maximum processing capability of AXC, and how many AXC that no matter is assigned with and takies is, when transmission data and processing, all the AXC to all signs handles.For example, suppose that the manageable AXC of system is 200, even the AXC that is assigned with has only 50, also can handle 200 AXC together.
Can distribute to other carrier waves for carrier resource deleted in the assurance system and use, preferably, further comprise following processing:
This step is for the processing of deleting carrier wave, and during the deletion carrier wave, the deletion action among BBP, BBI and the RRU does not require in same radio frames and finishes, and for the carrier wave of deletion, does not require that BBP, BBI and RRU's is synchronously strict.And deleted carrier resource (for example AXC0～7) can also be distributed to other newly-built carrier waves as required arbitrarily, thereby realizes can joining flexibly of vacant resource.
So far, the method flow in the present embodiment is finished.After handling by the way, for each carrier wave that has distributed, the resource that it is corresponding and transmission link all are static; Therefore, when a certain carrier wave was set up or deleted, resource and the transmission link of other carrier wave correspondences remained unchanged, and also just can not impact other carrier waves.
Lift a simple example, suppose that original carrier wave is C0, C1, C2, if leave out the C1 carrier wave, and RRU has deleted the relevant corresponding relation of C1 carrier wave in radio frames k, even BBP and BBI finish the deletion of carrier wave i and corresponding relation thereof synchronously in this radio frames k, because C0 and two carrier waves of C2 all do not have to the AXC position in the transmission link of BBI to change at BBP processing unit and BBP, so C0 and C2 can not be affected, affected only is C1, and since delete build carrier wave C1 delete build be exactly originally do not need to guarantee professional stable, so adopt this MECHANISM SOLUTION except between the system for synchronous strict demand.
Processing by the invention described above, make the dynamic resource pool technology guarantee that the static relatively and vacant resource of having joined resource in the pond can join flexibly, thereby the variation (carrier wave is deleted and built) that can avoid interior certain resource of resource pool causes other resources (carrier wave) in the pond is exerted an influence, and has guaranteed resource distribution and the seamless link of using side.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, is equal to replacement, improvement etc., all should be included within the scope of protection of the invention.
