Be described in further detail below in conjunction with the technical scheme of accompanying drawing the embodiment of the invention.
Particularly, at first, the power supply allocation list of base station PM subcard need be carried out the mapping resources definition.The power that the PM subcard is provided is defined as producer's resource, the AMC of needs power supply is defined as consumer's resource, between produces the mapping resources relation, thereby realizes the intelligent power supply configuration of wireless base station, to realize that automatic control and management is carried out in the power supply of wireless base system.
For above-mentioned mapping relations, giving data in wireless base station whole service process keeps, be stored in the flash memory (Flash), when the configuring condition that PM subcard or AMC are wherein arranged changes, according to the method that the embodiment of the invention provides, can be modified in these mapping relations of preserving among the Flash, and with the single-chip microcomputer managing process on this mapping relations real-time informing PM subcard, by the switch of its control power channel, thereby reach the intelligent switching controls that veneer is powered.
In actual applications, the startup of wireless base system is divided into initialization and normal two stages of operation, with the third generation (3rd-generation, abbreviate 3G as) TD SDMA (Time Division-Synchronous Code Division Multiple Access in the standard, abbreviating TD-SCDMA as) base station is for example, the process of data is an initial phase in basic controlling process power up wherein and the loading of databases, after initial phase finished, system entered normal operating phase.Wherein, the PM subcard can be defaulted as MCH in early days and power on, and after the MCMC of MCH control module starts, can send heartbeat (PM Heart Beat) instruction to the PM subcard cycle, makes the power management in PM subcard later stage be taken over by MCMC fully.The wireless base station needs the data of base station are configured before operation, and these data are stored in the database in advance by the Engineering Service personnel usually, in actual applications, and also data that may occur preparing and the actual inconsistent situation of hardware device.At system's external power supply, after base station system brought into operation, for processing shown in Figure 5 is followed in the AMC power supply, Fig. 5 was the overall mutual process flow diagram of power supply configuration of the embodiment of the invention, as shown in Figure 5, comprises following processing:
Step 501, embedded OS powers on;
Step 502, the embedded OS notification database is carried out data load and data initialization;
Step 503, network management system are carried out the data configuration of AMC and PM subcard in database;
Step 504, resource management module read the configuration data of PM subcard from database, and resources effective is tested; The initial information of PM daughter card configuration data is not clear and definite in the MicroTCA agreement.In the TD-SCDMA base station of 3G, the state of PM subcard is defaulted as unavailable, reports its state by resource management module by heartbeat message, and the rewrite data storehouse, and notice Configuration Manager PM subcard resource changes, and carries out power supply increment configuration flow.That is, regard effective PM subcard as a kind of resource, resource becomes when effective or invalid, needs the change resource pool, and changes mapping relations synchronously, adds or the AMC of this PM subcard power supply is used in deletion;
Step 505, resource management module read the AMC configuration data that needs power supply from database, this configuration data is write by the Engineering Service personnel usually, and after system's operation, network management system can be changed related data, to satisfy actual requirement.When resource management module reads the AMC configuration data of power supply, type according to AMC, obtain the required rated power of AMC, and according to the type priority ordering of powering, for example, in the TD-SCDMA base station, the Optical Fiber Interface Board that connects the BBU-RRU mouth is to guarantee radio frequency resource and the mutual prerequisite of base-band resource, need preferential power supply, the power supply of taking second place of base-band resource plate, other type is analogized.That is to say, need to determine the priority of power supply AMC earlier according to the AMC function type, and with in this priority writing system program; By AMC is carried out the standard inspection, can guarantee that the AMC of actual access base station is consistent with the AMC of webmaster personnel actual disposition, and power division is correct.
Step 506, the PM subcard resource that resource management module notice Configuration Manager can be used, wherein, the PM subcard resource that breaks down is disabled resource.
Step 507 is assigned to available PM subcard mapping resources on the AMC, obtains power supply power supply configuration relation.In a minute timing, priority order is arranged, and control, thereby can guarantee that the PM subcard can use rationally and effectively by power calculation, can overload operation, avoid energy dissipation simultaneously, improve the serviceable life of PM subcard.
Step 508, the configuration information of poll check AMC, whether check to have needs the AMC of power supply not obtain power division, if have, the PM subcard underpower of configuration is described, promptly, the power supply capacity deficiency, the notice network management system is handled, and network management system can reduce AMC or increase the PM subcard; The webmaster personnel by this power supply configuring condition is carried out the correctness inspection, and send the power supply Configuration Status Report for automatically the webmaster personnel, so that can handle in good time.
Step 509, Configuration Manager send the power supply configuration information to carrier management controller MCMC, and the MCMC control module carries out the break-make of corresponding power passage according to PM subcard resource in the power supply configuration information and AMC resource mapping relation.
The power supply of PM subcard is not disposed in the Micro TCA standard agreement and make regulation, might cause PM subcard overload situations, thereby influence the life-span of PM subcard, even cause the PM subcard to burn out, influence the telecommunication service of whole base station.The power of the maximum of trying one's best to provide can not interfered under the normal situation about using of PM subcard by above-mentioned processing.
Fig. 6 is the power on power supply configuration flow figure of original state of the system of the embodiment of the invention, as shown in Figure 6, comprises following processing:
Step 601, system powers on, and database loads;
Step 602, read initialization PM subcard resource P1, P2 ..., Pn and initialization AMC resource A1, A2 ..., Am;
Step 603, the initialization PM subcard resource that judgement is read and the availability of initialization AMC resource, if judge that available resources are arranged, execution in step 604, otherwise, execution in step 608;
Step 604, according to P1, P2 ..., Pn respectively to A1, A2 ..., Am calculates;
Step 605, whether the afterpower of judging Px is greater than the required power of Ax; If the judgment is Yes, then execution in step 606, otherwise execution in step 607;
Step 606 is provided with Ax and is power supply, and the Px afterpower reduces, and revises the power supply mapping relations on the Px, execution in step 609;
Step 607 is returned the power supply mapping relations, and execution in step 609;
Step 608 is returned power supply mapping relations configuration failure, and execution in step 609;
Step 609, circular test A1, A2 ..., the power supply state of Am, judge whether to exist the not Ax of power supply, if the judgment is Yes, then execution in step 610, otherwise execution in step 611;
Step 610, to the network management system report and alarm, and execution in step 612;
Step 611 is eliminated the not enough alarm of power supply capacity to network management system, and execution in step 612;
Step 612, the power supply configuration messages that sends Px is to MCMC, by MCMC power on/off source channels switch.
From above-mentioned processing as can be seen, at initial phase, the embodiment of the invention produces legal mapping resources relation by producer's power and consumer's power are calculated, and can guarantee that PM card and AMC can rationally utilize, and improves serviceable life.When initialization, system may connect a PM subcard, also may connect two PM subcards, in Micro TCA standard, has stipulated that the PM card is defaulted as MCH power supply, and promptly the MCH acquiescence powers on, thereby has guaranteed the acquisition and the detection with resource of obtaining of data.After the MCMC of MCH started, power-supply system entered and is subjected to MCMC control in the time of the stage, and this moment, the work of power supply was controlled by the MCMC module fully, and MCMC can set the power supply configuration of power supply according to user's collocation strategy.In Micro TCA standard, the PM subcard to the principle that AMC powers is: when a certain power channel was powered, the on-off switch of PM subcard Px (x=1...n) was opened, and the power supply output load is by the power supply of PM subcard.Opening of these on-off switches carried out by MCMC module controls PM subcard.
Can find from last surface analysis, when initialization, to AMC power the configuration after, produced certain mapping relations between PM card power resource and the AMC resource.But, when wherein a certain resource situation changes, produced problem how to adjust these mapping relations.
In the wireless base station applications, when initialization, there is not the difference of priority or grade between the AMC, still, in case after producing the power supply allocation map, AMC has produced respectively, after the AMC operation of some power supplies, the base band radio frequency resource relations of distribution have been arranged, set up wireless area, might there be a plurality of users inserting this sub-district, carry out voice and exhale logical or other telecommunication service.Therefore, under the situation that changes a certain resource, need guarantee as much as possible that user's telecommunication service is normal, interference-free.
According to the technical scheme of the embodiment of the invention, when the AMC resource changes, keep the power supply configuration relation of unchanged AMC, to the AMC that changes, if newly-increased AMC, the PM subcard has available horsepower, then powers, if cancellation AMC, the power supply mapping is regained in then cancellation power supply, checks the AMC that whether has the inactivity mapping simultaneously, under the situation of the AMC that determines to exist the inactivity mapping, this AMC is distributed.
When PM subcard resource changes, for example, there is a PM subcard to break down, this moment and the AMC that this PM subcard shines upon,, will descend owing to lacked producer's power.In actual applications, it is available having an other PM subcard, and the mapping of the power on it does not reach state of saturation.In the prior art, the MicroTCA standard is not clearly when a PM subcard breaks down, how this handles by the AMC subcard of its power supply, in addition, there is defective in the active and standby PM subcard mode of operation that prior art provides, because the power that every PM subcard can provide is limited, generally can dispose 12 AMC based on MicroTCA standard base station, if every PM subcard can provide 200 watts power, and every AMC needs 30 watts power, then a PM subcard can't satisfy the power supply that surpasses 7 AMC, and this moment, active/standby mode did not have practical significance.
The PM subcard load sharing method of supplying power to that Micro TCA standard provides, not clearly when a PM subcard fault, how the power supply of AMC is handled.The intelligent power supply collocation method that the embodiment of the invention provides can recover the power supply of AMC to greatest extent, reaches the control purpose of Autonomic Migration Framework.When PM subcard fault, regularly detect by the resource management process, notice configuration management process, the PM resource changes, this moment, the AMC to the power supply of the mapping on this PM subcard descended electricity, detected remaining PM resource then, if available power resource is arranged, then the AMC that does not power on is carried out the power mapping, thereby reach the purpose of power supply mapping Autonomic Migration Framework.And previous not electric down AMC power supply relation remains unchanged, so as much as possible guaranteed the telecommunication service under the system-level malfunction situation, and need not manual intervention, in the shortest time, recover telecommunication service as much as possible automatically, be specially adapted to outdoor wireless base station.Below in conjunction with Fig. 7 technique scheme of the present invention is elaborated.Processing flow chart when Fig. 7 changes for the PM subcard of the embodiment of the invention and AMC as shown in Figure 7, comprises following processing:
Step 701, system normally moves;
Step 702 receives PM subcard resource and AMC resource increment message;
Step 703 is if the state of definite PM subcard Px is by unavailable available (this PM subcard is for newly plugging or fault recovery), then the execution in step 707-step 708 of becoming;
Step 704, state that determine to determine PM subcard Px is by available unavailable (this PM subcard fault or be pulled out), then the execution in step 709-step 711 of becoming;
Step 705 is if determine to increase newly an AMC, then execution in step 712-step 713;
Step 706 needs if determine the power supply of an AMC of cancellation, then execution in step 714-step 716;
Step 707 detects whether there is the Ax resource that does not power on;
Step 708 if exist, then powers on to this Ax, otherwise alarms, execution in step 717;
Step 709, the Ax that this PM subcard Px is gone up all power supplies descends;
Step 710 detects whether also have available power;
Step 711, if the judgment is Yes, to the Ax that the does not power on distribution of powering, execution in step 717;
Step 712, whether Px also has spendable power in poll check;
Step 713 if the judgment is Yes, then goes up electric treatment to the AMC that increases newly, otherwise the alarming processing of being correlated with, execution in step 717;
Step 714, the AMC that cancellation is powered descends electric treatment, regains the power resource of distributing to this AMC simultaneously;
Step 715 judges whether also to exist the AMC that does not power on;
Step 716 if the judgment is Yes, judges then whether power satisfies the AMC that this does not power on, if satisfy, then goes up electric treatment, otherwise, carry out alarming processing, execution in step 717;
Step 717, with alarm data informing network system, the configuration data of will powering sends to carrier controller;
Step 718 finishes the increment flow process.
By above-mentioned processing, guaranteed that as much as possible telecommunication service is unaffected, and the power of PM subcard is provided most possibly.
In actual applications, MCMC also can be by manually changing resource status, for example to the control of power supply, though PM subcard resource #2 is provided, but not configuration in database, at this moment, PM subcard resource #2 reality does not provide power, promptly do not enter the power supply mapping relations, can increase this PM subcard resource #2 this moment in network management system, can delete PM subcard resource # 1 simultaneously, thereby reach the purpose of auto switching.The function of standby PM is used and verified to the burden of each PM module in the distribution system so balancedly.
Below, the specific operation process of the inventive method is described by a concrete example.According to present use 3G TD-SCDMA standard, and follow the NodeB base station situation that the MicroTCA standard design realizes, in this base station system, have 2 PM subcards, the first power supply PM1, second source PM2, two block power supplies all can provide 100 watts power.And need this moment to power for AMC1, AMC2, AMC3, AMC5, AMC6, AMC7, AMC8, AMC9.Wherein, AMC5, AMC6 are the Optical Fiber Interface Board of following the BBU-RRUIr interface protocol, and its rated power is 20 watts.AMC1, AMC2, AMC3 are for moving the baseband processing unit plate of digital signal processing, and its rated power is 35 watts.AMC7 is the clock control subcard, and rated power is 10 watts; AMC8 is transmission control subcard, and rated power is 10 watts; AMC9 is an integrated monitoring unit subcard, and rated power is 5 watts.
When initialization, the first power supply PM1 is AMC5, AMC6, AMC8, AMC1, AMC7, AMC9 power supply according to the priority initial configuration, 0 watt of afterpower; The AMC that residue can't be powered is powered by PM2, is respectively AMC2, AMC3,30 watts of afterpowers.The mapping relations between PM power supply resource and the AMC consumption of natural resource have been produced.Be respectively that PM1 is corresponding to AMC 5, AMC 6, AMC8, AMC 1, AMC 7, AMC 9; PM2 is corresponding to AMC 2, AMC 3.Two PM need open the power channel of base station backboard when AMC is powered.Specifically comprise following processing.
Step 2, the resource management process detects the PM1 fault, and notice Configuration Manager PM1 becomes unavailable.
