Describe radio frequency resource dispatch control method of the present invention in detail through specific embodiment below.
Embodiment one:
The radio frequency resource dispatch control method that the embodiment of the invention one provides, its flow process is as shown in Figure 2, comprises the steps:
Step S101: the operating state that periodically detects transceiver.
Periodic queries is carried out through BP in the base station; Unusual in order to have judged whether the transceiver operating state; In case note abnormalities; Then report fault to arrive radio frequency resource scheduling controlling device, this device can be arranged in the main control unit of base station, and controls the completion subsequent operation by radio frequency resource scheduling controlling device.
Periodically detect the operating state of each transceiver in this step with first sense cycle of setting; Realize the control of first sense cycle through starting timer 1; So that the operating state of all transceivers under each sector of having jurisdiction in periodicity base stations detected self system; If it is unusual to have detected the transceiver operating state, execution in step S102, otherwise continue to detect.
Transceiver related after detecting the radio frequency resource operation attitude obturation that causes owing to the RRU hardware or software failure is inaccessible; Think that this RRU operating state is unusual, so confirm this RRU related transceiver unusual because of its related RRU damages operating state.
Step S102: when having detected transceiver and break down, judge whether all related RRU of the transceiver that breaks down are all unavailable.
If execution in step S103 continues execution in step S102 otherwise return.
When having detected the transceiver operating state when unusual, poll detect this transceiver that breaks down related all RRU whether all unavailable, when the test results is yes, it is unavailable to confirm to detect all related RRU of the logic transceiver that breaks down.
Radio frequency resource scheduling controlling device receives after the Trouble Report from BP, can be according to current configuration, and all RRU that are associated with the fault transceiver of poll, judgement is by poll RRU resource failover and unavailable whether.If detect the transceiver that breaks down related all RRU failover unavailable, then execution in step 103, continue to detect otherwise return step 101.
Step S103: whether idle RRU is arranged in the sector under the detection failure transceiver.
Radio frequency resource scheduling controlling device continues to detect in the affiliated sector of this fault transceiver whether other idle RRU are arranged, and wherein idle RRU is meant that the RRU physical entity normally moves, but does not have the RRU related with any one transceiver.
If, execution in step S104, otherwise execution in step S105.
Step S104: select RRU idle in the affiliated sector to use for the fault transceiver.
During initial configuration, the RRU quantity that generally disposes in each sector is greater than the quantity that equals transceiver in the base station, so that can be when the RRU fault is arranged, can preferentially use the idle RRU of this sector to replace the RRU that breaks down and use for the fault transceiver.
Step S105: inquire about whether there is idle critical RRU in other sectors.Wherein, critical RRU is the RRU of the striden sector scheduling of setting in advance.
Whether other all sector lower critical RRU operating positions in the website of radio frequency resource scheduling controlling device poll place, searching has critical RRU idle.Whether wherein, being inquired about RRU is critical RRU resource, by the configuration decision of OMC.
If execution in step S106 continues execution in step S107 otherwise return.
Step S106: select critical RRU idle in other sectors to use for the fault transceiver.
When in finding other sectors, having idle critical RRU, select critical RRU idle in other sectors to use for the fault transceiver.After selecting critical RRU idle in other sectors,, dispose RRU parameter and the electrical tilt antenna angle of critical RRU according to the needs of fault transceiver; Replace the fault transceiver fault RRU of the affiliated sector of use before with the critical RRU after the configuration.
When promptly the critical RRU of a free time in selecting other sectors uses, dynamically adjust this critical RRU parameter and supporting electrical tilt antenna angle, in order to replace fault RRU.At this moment, it is unavailable fault RRU being set.
Wherein, the adjustment work of supporting electrical tilt antenna angle is accomplished by RRU self control, and the RRU parameter of adjustment is then accomplished by radio frequency resource scheduling controlling device, and is handed down to this critical RRU.
Step S107: process ends or search the RRU that has taken in other sectors and whether can discharge to the fault transceiver and use.
When other can search the critical RRU that all searches in the sector less than the free time; Can think does not have suitable critical RRU and process ends; Preferably, can also search the critical RRU that has distributed in other sectors, see whether to belong to discharge the critical RRU that uses to the fault transceiver.
Embodiment two:
The radio frequency resource dispatch control method that the embodiment of the invention two provides, its flow process is as shown in Figure 3, comprises the steps:
Step S201: the operating state that periodically detects transceiver.
Referring to step S101.
Step S202: when having detected transceiver and break down, judge whether all related RRU of the transceiver that breaks down are all unavailable.
If execution in step S203 continues execution in step S201 otherwise return.
Referring to step S102.
Step S203: whether idle RRU is arranged in the sector under the detection failure transceiver.
Referring to step S103.
If, execution in step S204, otherwise execution in step S205.
Step S204: select RRU idle in the affiliated sector to use for the fault transceiver.
Referring to step S104.
Step S205: whether the channel of sector is all occupied under the detection failure transceiver.
Different with embodiment one is, in other sectors of inquiry, whether have idle critical RRU before, whether the channel of sector all occupied under the detection failure transceiver.When being judged as when being, carry out the step that whether has idle critical RRU in other sectors of inquiry again.Continue execution in step S201 otherwise return.
The situation that takies of current all channels in the affiliated sector of inquiry fault transceiver in this step; Baseband portion by BBU is accomplished this function; Specifically by reporting radio frequency resource scheduling controlling device after the BP statistics; After radio frequency resource scheduling controlling device statistics,, but channel idle is arranged if confirm that not all channel is all occupied.Explain that then the fault of fault transceiver does not have influence on the work of whole sector, also can consider to end this this moment and detect, wait for the detection case of next cycle.
Step S206: inquire about whether there is idle critical RRU in other sectors.Wherein, critical RRU is the RRU of the striden sector scheduling of setting in advance.
Referring to step S105.
If execution in step S207 continues execution in step S208 otherwise return.
Step S207: select critical RRU idle in other sectors to use for the fault transceiver.
Referring to step S106.
Step S208: according to the channel occupancy situation of the critical RRU that has distributed in other sectors, whether inquiry exists releasable critical RRU.
When in finding other sectors, not having idle critical RRU, the channel occupancy situation of inquiring about the critical RRU that has distributed in other sectors according to the channel occupancy situation of the critical RRU that has distributed in other sectors, searches whether there is releasable critical RRU; If, execution in step S209; Otherwise, execution in step S210.
The unoccupied channel quantity of the critical RRU that has distributed according to other sectors judges whether this critical RRU is releasable RRU; When the unoccupied channel quantity of the critical RRU that has distributed all surpassed the amount threshold of setting in second sense cycle of setting quantity continuously, definite this critical RRU was releasable critical RRU.Preferably, the product of second sense cycle and setting quantity is less than first sense cycle.
In this website of radio frequency resource scheduling controlling device poll all other comprise and distribute the sector channel of critical RRU to take situation; If have in the critical RRU unoccupied channel N continuous cycle of having distributed all above preset threshold, think that the critical RRU that has distributed can discharge.
Report transceiver channel occupancy situation by BP in this step and calculate the channel occupancy situation of each sector; Base station main control unit opening timing device 2; Being used for periodically, aggregate channels takies situation; If a certain sectors free channel number that a N continuous cycle BP reports surpasses threshold value, show that then the critical RRU that deprives under this sector does not influence the operate as normal of this sector.Wherein, the timer 2 cycle duration multiply by N must be less than the cycle duration of cycle timer 1.
Preferably, consider efficient and take into account the stability of system, preset threshold can be comprised the channel maximum number by a transceiver, to guarantee the robustness of whole system.
Step S209: use to the fault transceiver releasable critical RRU.
When finding when having releasable critical RRU; The resource of releasable critical RRU is discharged, dynamically adjust RRU parameter and the supporting electrical tilt antenna angle of critical RRU, in order to replace fault RRU; It is unavailable that fault RRU is set simultaneously, during configuration with reference to step S106.
The RRU configuration parameter is switched and may be caused unusual call drop phenomenon, but considers the index and the disaster tolerance property of whole system, and a small amount of unusual call drop allows.
Step S210: the priority of the affiliated sector of comparison fault transceiver and all have been distributed the priority of the sector under the critical RRU.
When not having releasable critical RRU, can consider to select to have distributed critical RRU to use for the fault transceiver the sector of priority of the sector under priority is lower than the fault transceiver.
Through all comprise the sector priority of distributing critical RRU in this website of poll, search priority and be lower than the affiliated sector of fault RRU and comprise the sector of distributing critical RRU.
In this step, the priority of each sector is preestablished by OMC, is handed down to the base station as parameter, and poll work is carried out by radio frequency resource scheduling controlling device, and the high priority sector more has authority to take critical RRU than low priority sector.
Step S211: whether exist priority be lower than the sector under the fault transceiver priority comprise the sector of distributing critical RRU.
If, execution in step S212; Otherwise finish this flow process, return and continue execution in step S201.
Step S212: select to have distributed critical RRU the sector of the priority of the sector under priority is lower than the fault transceiver.
Preferably,, all choose the minimum sector of priority in comprising the low priority sector of distributing critical RRU.
Step S213: whether (Broadcast Control Channel, BCCH) transceiver is bound with BCCH to detect the critical RRU of selection.
Select priority to be lower than the critical RRU of distribution in the sector of priority of the sector under the fault transceiver, judge the critical RRU that selects whether with affiliated sector in transceiver bind.
Whether the critical RRU that particular exam is selected binds with the BCCH transceiver, if then execution in step 212, otherwise execution in step 213.General base station is when carrying out transceiver and RRU binding; The non-critical RRU of preferential selection binds; Therefore, in case the situation of critical RRU and the binding of BCCH transceiver occurs, explain that then the affiliated sector of selected critical RRU also is faced with the situation of the shortage of RRU; Deprive its critical RRU this moment is inappropriate, otherwise the serious situation that interrupt the sector can appear in the sector under the selecteed critical RRU.
Among step S212 and the step S213, all detect decision making algorithm and carry out by radio frequency resource scheduling controlling device.
If, execution in step S214; Otherwise execution in step S215.
Step S214: will from alternative critical RRU, delete with the critical RRU that the BCCH transceiver is bound.
Return step S212 again under priority is lower than the fault transceiver selection in other sectors of sector priority distributed critical RRU.
Step S215: distributed critical RRU to use for the fault transceiver with selecteed.
Distributed critical RRU for selecteed, discharged the resource of this critical RRU by force, dynamically adjusted RRU parameter and the supporting electrical tilt antenna angle of critical RRU, in order to replace fault RRU, it is unavailable that fault RRU is set simultaneously, during configuration with reference to step S106.
The RRU configuration parameter is switched and may be caused unusual call drop phenomenon, but considers the index and the disaster tolerance property of whole system, and a small amount of unusual call drop allows.
Step S212 has realized to step S214 the sector of sector priority under priority is lower than the fault transceiver, selects to have distributed critical RRU to use for the fault transceiver.
