Description
Technical field
The present invention relates to communication technical field, particularly relate to the management method and the equipment of the processing resource among a kind of BBU.
Background technology
BBU (Building Base band Unit is generally adopted in existing base station; Indoor baseband processing unit)+and RRU (Radio Remote Unit, Remote Radio Unit) framework, promptly single BBU connects a plurality of RRU; Each RRU connects antenna respectively and covers different sectors; Wherein BBU is responsible for Base-Band Processing, and RRU is responsible for radio frequency processing, and the two connects through optical fiber interface.
Present 2G (2nd Generation; Second generation mobile communication technology)/3G (3rd Generation; Third generation mobile communication technology) system belongs to traditional narrowband systems; Base-Band Processing is comparatively simple, and ((Digital Signal Processing, Digital Signal Processing) device processing apparatus can be accomplished whole Base-Band Processing of one or more sectors to single DSP in interior monolithic base band integrated circuit board of BBU or the integrated circuit board.
As shown in Figure 1, be the sketch map of traditional base station of the prior art hardware composition structure.

Embodiment
To combine the accompanying drawing among the present invention below, the technical scheme among the present invention is carried out clear, complete description, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope that the present invention protects.
As shown in Figure 4, the schematic flow sheet for the management method of the processing resource among a kind of BBU that the embodiment of the invention proposed specifically may further comprise the steps:
Step S401, a plurality of DSP devices that BBU comprised are divided into a plurality of DSP resource pools.
Wherein, comprise one or more DSP devices in each DSP resource pool respectively, the resource in each DSP resource pool is respectively applied for the processing that realizes one or more types, and the processing capacity that resource realized in each DSP resource pool is different.
With concrete enforcement scene is example, and above-mentioned DSP resource pool is divided, and the function allocative decision specifically comprises:
Resource in the one DSP resource pool is used to realize the processing of all upper-layer protocols;
Resource in the 2nd DSP resource pool is used to realize the encoding and decoding processing, and modulation is handled;
Resource in the 3rd DSP resource pool is used to realize the processing that all many antennas are relevant;
The common completion among the said BBU of a said DSP resource pool, said the 2nd DSP resource pool and said the 3rd DSP resource pool need be carried out complete information process.
Above-mentioned processing is a kind of preferred realization scene, and in practical application, the division numbers of DSP resource pool and function are distributed and can be adjusted according to actual needs, and such variation can't influence protection scope of the present invention.
Need further be pointed out that; Can be according to actual needs; Each logical process function is independently of one another fully, set up corresponding DSP resource pool respectively, also can a plurality of logical process functions be combined according to resource requirement amount or the position in handling process; Form treatment combination, and use a DSP resource pool to realize the processing of each logic function in the treatment combination.
In practical application; For the complete process flow that need carry out among the BBU; Fully independently the form of a treatment type is divided, and also can be divided into a plurality of treatment combinations, and the mode that perhaps combines with independently treatment type and treatment combination is divided; The criteria for classifying of corresponding D SP resource pool is corresponding with it, and the variation of such division foundation can't influence protection scope of the present invention.
In concrete enforcement scene, the processing of this step specifically comprises:
The number of types of the processing that realizes as required and/or the quantity of treatment combination with a plurality of DSP devices that this BBU comprised, are divided into the DSP resource pool of respective numbers.
Wherein, concrete dividing mode comprises following two kinds:
Mode one, the average division.
The DSP resource pool quantity of setting up as required on average is divided into the set of respective numbers with the DSP device among the BBU, and the DSP device in each set is formed a DSP resource pool, and the quantity of the DSP device that comprised of each DSP resource pool of obtaining of division is identical like this.
Such dividing mode can have easier partition process, and higher division efficient also can be convenient aspect the circuit deployment.
Mode two, division in proportion.
The quantity of the DSP device of confirming according to certain rule to be comprised in each DSP resource pool; For example; According to the processing and/or the treatment combination resource needed ratio of the required realization of each DSP resource pool, confirm the ratio of the quantity of the DSP device that each DSP resource pool is comprised.
Because the quantity of the resource that DSP device can provide is certain; So,, can distribute more DSP device for the DSP resource pool that needs take more resources through such dividing mode; It is had more can arrange resource, realize more reasonably resource allocation.
Have above explanation to know, two kinds of above-mentioned dividing mode respectively have the advantage of self, in concrete enforcement scene, can confirm as required to select which kind of dividing mode, specifically select which kind of dividing mode can not influence protection scope of the present invention.
Step S402, when said BBU need handle current institute information transmitted; Said BBU is according to current said processing resource needed amount; In the pairing DSP resource pool of the type of said processing, select corresponding resource to realize said processing, and close the pairing DSP device of residual resource.
Because the resource in the DSP resource pool is provided by each DSP device; So; For the management of resource, be actually dispatching management, in the present technique scheme to each the DSP device in the DSP resource pool; In order to realize better practicing thrift well, be presented as the startup during each DSP and close for the dispatching management of each DSP device.
Based on above-mentioned technological thought, the actual mechanical process of this step is following:
Said BBU is according to current said processing resource needed amount; In the pairing DSP resource pool of the type of said processing; Startup can provide the DSP device with the corresponding resource of said stock number; And the resource of the DSP device that passes through to be started realizes said processing, and closes the pairing DSP device of residual resource.
After accomplishing above-mentioned processing; Also further comprise follow-up dynamic resource management process in the technical scheme that the embodiment of the invention proposed; Promptly, open or close the DSP device, realize the more effective utilization of resources according to the variation adjustment resource allocation of occupation condition.
According to the difference of set concrete resource management rule, follow-up dynamic resource management process comprises following two kinds of situation:
Situation one, the situation that takies of only considering the DSP device are carried out resource management.
Occupation condition among each DSP that the detection that BBU implements has started judges whether to exist idle DSP device, and wherein, said idle DSP device is specially the DSP device that own resource is entirely idling-resource.
When the idle DSP device of current existence in the DSP device that said BBU confirms to have started, said BBU closes idle DSP device.
When the resource that the DSP device of confirming to have started as said BBU is provided can not satisfy when pre-treatment resource needed amount, said BBU selected a current DSP device of closing to start in said DSP resource pool, and new resource is provided.
Situation two, combination sector service conditions are taken all factors into consideration the occupation condition of idling-resource reservation and DSP device and are carried out resource management.
At first, said BBU monitor current institute information transmitted the service conditions of corresponding sector, it is interval to confirm as the idling-resource that said sector keeps.
Interval definite can the making of such idling-resource reserves the resource requirement that corresponding standby resources guarantees that the service traffics variation is brought in the DSP resource pool; The raising system guarantees professional carrying out smoothly for the adaptibility to response of flowed fluctuation, and; Interval in conjunction with the determined idling-resource of sector service conditions; Be according to the business statistics situation in the sector and definite, make the idling-resource that is kept be in reasonable range, can not cause the too much wasting of resources.
On the other hand, said BBU detects the current idling-resource amount in the DSP device that has started.
When said BBU confirms that current idling-resource amount is lower than the minimum idle resource value in the said idling-resource interval; Said BBU selects a current DSP device of closing to start in said DSP resource pool, and with the resource of the DSP device of new startup as new idling-resource;
When said BBU confirmed that current idling-resource amount is higher than the highest idle resource value in the said idling-resource interval, said BBU closed the DSP device that only comprises idling-resource.
In the application scenarios of reality, the idling-resource interval can be a numerical value interval that comprises the highest idle resource value and minimum idle resource value, also can be a concrete numerical value, and promptly the highest idle resource value and minimum idle resource value are same numerical value.Such variation does not influence protection scope of the present invention.
Compared with prior art, the technical scheme that the embodiment of the invention proposed has the following advantages:
Through using the technical scheme that the embodiment of the invention proposed, can be the DSP resource pool with the processing resource division among the BBU according to processing capacity, call corresponding resource according to current resource needed amount; And close remaining DSP device, thereby sharing of resource handled in pairing many sectors realization to BBU; Can promote hardware resource utilization; Realize to handle reasonable resources scheduling and management, and in the sector when load is light, according to service conditions cutoff DSP device; Do not influencing under the Network situation, reaching the purpose of saving power consumption.
Below, the application scenarios in conjunction with concrete further specifies the technical scheme that the embodiment of the invention proposed.
Of background technology, based on existing logic and hardware structure, can't carry out hardware resource optimization or shutoff according to the situation that traffic load changes, there is more high-power waste.
Based on such defective; The embodiment of the invention has proposed a kind of to the new BBU realization framework of LTE broadband system; Can under the prerequisite that does not influence the network coverage and customer service, reach energy-saving and cost-reducing target according to the DSP device of closing the free time of load variations in good time.
Target based on abundant lifting Base-Band Processing device utilance, reduction BBU power consumption; Realize identical logic function module in view of all adopting identity unit in the former different baseband processing units with structure; Therefore under the prerequisite that guarantees the backboard exchange capacity; Can consider to adopt the Base-Band Processing framework based on resource pool, Base-Band Processing all among the promptly same BBU are divided into the different logical functional pool according to the Different Logic function, are distributed to identity logic function in the different base band integrated circuit boards and concentrate by the device of smaller amounts and handle former; The not corresponding fixing Base-Band Processing hardware of each sector RRU, but from above-mentioned baseband pool, distribute the corresponding resource of handling according to the actual requirements.Concrete logical construction sketch map is as shown in Figure 5.
Further; With reference to two kinds of dividing mode among the aforesaid step S401; The embodiment of the invention is an example with the BBU structure that comprises 9 DSP devices, explains respectively according to two kinds of dividing mode resulting DSP resource pool splitting schemes and follow-up processing resource management scheme.
Mode one, the average division.
Confirm that at first whole logical process process comprises two logical process functions and a treatment combination, according to corresponding execution sequence, is respectively:
(1) upper-layer protocol is handled;
(2) treatment combination of being formed is handled in encoding and decoding, modulation;
(3) many antennas relevant treatment.
Divide based on above flow process, in BBU, need set up 3 DSP functional pools; To realize above-mentioned function and function combinations respectively; Hardware configuration is formed as shown in Figure 6, and wherein, DSP functional pool 1 is responsible for all upper-layer protocols and is handled; DSP functional pool 2 is responsible for all encoding and decoding, modulation is handled, and DSP functional pool 3 is responsible for all many antennas relevant treatment.
Owing to be average division, so each DSP functional pool is made up of 3 DSP devices shown in Fig. 6.
When concrete the realization, can start one or more DSP devices and bear corresponding processing according to the real resource demand.At this moment, the processing resource of each DSP functional pool is three sectors and shares, and can distribute the handled resource according to each sector active user and business demand, avoids must distributing in the similar traditional structure whole DSP device resource to give certain sector.
Mode two, division in proportion.
Similar with mode one, confirm that equally whole logical process process comprises two logical process functions and a treatment combination, according to corresponding execution sequence, is respectively:
(1) upper-layer protocol is handled;
(2) treatment combination of being formed is handled in encoding and decoding, modulation;
(3) many antennas relevant treatment.
Further consider that each handles and treatment combination resource needed amount, it is the highest to obtain (2) middle resource needed amount, secondly is (3), need stock number minimum be (1).Consider among the BBU that one has during 9 DSP, confirm that thus (1), (2), the needed DSP number of devices of (3) pairing DSP resource pool are respectively 2,4,3.
Divide based on above flow process, in BBU, need set up 3 DSP functional pools; To realize above-mentioned function and function combinations respectively; Hardware configuration is formed as shown in Figure 7, and wherein, DSP functional pool 1 is responsible for all upper-layer protocols and is handled; DSP functional pool 2 is responsible for all encoding and decoding, modulation is handled, and DSP functional pool 3 is responsible for all many antennas relevant treatment.
When concrete the realization, can in each DSP resource pool, start one or more DSP devices and bear corresponding processing according to the real resource demand.At this moment, the processing resource of each DSP functional pool is three sectors and shares, and can distribute the handled resource according to each sector active user and business demand, avoids must distributing in the similar traditional structure whole DSP device resource to give certain sector.
After accomplishing above-mentioned DSP resource pool division, for the application process of reality, each DSP resource pool is born the service traffics of three sectors simultaneously, as long as three sectors do not reach 100% load simultaneously, all can have the processing resource redundancy in each DSP functional pool.
So, according to preset DSP device shuts off rule (being the situation one and situation two among the aforesaid step S402), respectively the DSP device in each DSP resource pool is carried out resource management.
For situation one, as long as idle fully DSP device occurs, promptly close, reach resources conservation to greatest extent; But, in situation as shown in Figure 8, might cause owing to there is not reserved resource; After making that the current business flow increases, must realize replenishing of resource, can need the time owing to DSP device start-up course through starting new DSP device; Can cause the situation that occurs inadequate resource during this period, thereby traffic affecting is realized normally.
For situation two, need to have confirmed the idling-resource of reservation in advance, so; In each DSP resource pool, each DSP device of startup not only requires to guarantee normal Business Processing resource needed, also need provide enough idling-resource as standby resources; Thereby, guarantee when service traffics increase, can directly call standby resources and proceed Business Processing; And when idling-resource is too much, can close the DSP device, to reduce the idling-resource total amount; And when current idling-resource is not enough, then need start new DSP device, replenish idling-resource.Such scheme has improved the resource reliability of Business Processing, and still, the existence of idling-resource has still caused certain extra energy consumption.
In concrete realization scene, specifically adopt above-mentioned which kind of scheme to adjust according to actual needs, such variation does not influence protection scope of the present invention.
