Detailed description of the invention

In order to make the technical problem to be solved, technical scheme and beneficial effect clearer, bright In vain, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that herein Described specific embodiment, only in order to explain the present invention, is not intended to limit the present invention.

The embodiment of the present invention provides a kind of radio frequency resource dispatch control method, arranges critical RRU, Qi Zhongshe The critical RRU put is can be across the RRU, this kind of critical RRU of sector scheduling and other RRU in website Hardware is identical, and meets following condition:

One adjacent part being in each sector.

When constructing in base station, although different sectors covers different regions, but under same website, Between each sector, after all having adjacent part, critical RRU is positioned at this class region.

Two is to complete the scheduling across sector.

Critical RRU typically equips high performance electrical tilt antenna, in order to by antennal interface criterion group (Antenna Interface Standards Group, AISG) interface protocol controls the inclination angle of antenna so that The RRU connecting the same antenna only relies on the amendment of logic parameter, can complete from a sector to other The scheduling configuration of individual sector, i.e. dispatches across sector, thus need not carry out construction and adjust, it is also possible to keep more Preferably coverage.

In sum, critical RRU meets following condition: critical RRU and common RRU hardware configuration phase With；Critical RRU riding position is positioned at the adjacent position of affiliated sector and other sectors；Critical RRU joins It is set to dispatch across sector.

It is illustrated in figure 1 the system principle schematic diagram that critical RRU is set.With a S3/3/3 website it is Example, only gives part related to the present invention in Fig. 1, it will be understood by those skilled in the art that base station has There are other functions and structure, but these are not in the range of the discussion of the present invention.

As shown in Figure 1, base station includes BBU and RRU two parts, and RRU includes common RRU With critical RRU two kinds, different RRU is distributed under different sectors.The most critical RRU is building Stand construction time must the layout adjacent in each sector, be equipped with electrical tilt antenna, concrete by networking of its number Require to determine.As the RRU1 in Fig. 1, RRU2 ..., RRUn broadly fall into common RRU.Respectively The corresponding relation of RRU and transceiver is by base station sets, when there being noncritical common RRU, the most excellent First transceiver is arranged on noncritical RRU, in order to critical RRU is remained consequent malfunction and switches Time use..

It is also preferred that the left as it is shown in figure 1, after networking requirement determines, it is also possible to carry out parameter configuration.Ginseng Number configuration is completed by operation maintenance center (Operations & Maintenance Centre, OMC) and unified It is handed down to each base station, can be completed down by base station controller (Base Station Controller, BSC) when issuing Send out.

The radio frequency resource dispatch control method of the present invention is described in detail below by specific embodiment.

Embodiment one:

The radio frequency resource dispatch control method that the embodiment of the present invention one provides, its flow process is as in figure 2 it is shown, wrap Include following steps:

Step S101: be periodically detected the duty of transceiver.

Base station is periodically interrogated by BP, different in order to determine whether transceiver duty Often, once note abnormalities, then reporting fault is to radio frequency resource dispatching control device, and this device can be arranged on In the main control unit of base station, and controlled subsequent operation by radio frequency resource dispatching control device.

This step detects the duty of each transceiver with the first detection cycle set, logical Cross startup intervalometer 1 and realize the control in the first detection cycle, in order to be periodically detected in its own system of base station The duty of all transceivers under each sector administrative, if be detected that there is transceiver duty Abnormal, perform step S102, otherwise continue detection.

Related when detecting after the radio frequency resource caused due to RRU hardware or software failure operates state obturation Transceiver inaccessible, it is believed that this RRU duty is abnormal, and then confirms the transmitting-receiving associated by this RRU Duty is abnormal because its RRU associated damages for letter machine.

Step S102: when having detected that transceiver breaks down, it is judged that the transceiver broken down All RRU of association are the most unavailable.

If so, perform step S103, otherwise return and continue executing with step S102.

When transceiver duty exception having been detected, poll detects this transceiver broken down Associated all RRU are the most unavailable, when the test results is yes, determine and detect and break down Logic transceiver association all RRU unavailable.

Radio frequency resource dispatching control device receives after the Trouble Report of BP, can basis be currently configured, The all RRU being associated with fault transceiver of poll, it is judged that whether polled RRU resource is because of fault Unavailable.If be detected that all RRU associated by the transceiver broken down are unavailable because of fault, Then perform step 103, otherwise return step 101 and continue detection.

Step S103: RRU the most available free in sector belonging to detection fault transceiver.

Whether radio frequency resource dispatching control device has other in continuing to detect sector belonging to this fault transceiver Idle RRU, wherein idle RRU refer to that RRU physical entity is properly functioning, but not with any one The RRU of individual transceiver association.

If so, perform step S104, otherwise perform step S105.

Step S104: RRU idle in sector belonging to selecting uses to fault transceiver.

When base station initial configuration, in general each sector, the RRU quantity of configuration is greater than equal to transmitting-receiving letter The quantity of machine, so as to when there being RRU fault, can preferentially use the idle RRU of this sector to replace Change the RRU that breaks down to use to fault transceiver.

Step S105: whether there is the critical RRU of free time in inquiring about other sectors.Wherein, critical RRU is the RRU that can dispatch across sector pre-set.

In the website of radio frequency resource dispatching control device poll place, other all sector lower critical RRU use feelings Condition, has searched whether that critical RRU is idle.Wherein, it is queried whether RRU is critical RRU resource, Determined by the configuration of OMC.

If so, perform step S106, otherwise return and continue executing with step S107.

Step S106: critical RRU idle in selecting other sectors uses to fault transceiver.

When there is the critical RRU of free time in finding other sectors, select idle facing in other sectors Boundary RRU uses to fault transceiver.After critical RRU idle in selecting other sectors, according to fault The needs of transceiver, configure RRU parameter and the electrical tilt antenna angle of critical RRU；With facing after configuration Boundary RRU replaces fault RRU of the affiliated sector used before fault transceiver.

I.e. when selecting an idle critical RRU in other sectors to use, dynamically adjust this critical RRU parameter and supporting electrical tilt antenna angle, in order to replace fault RRU.Now, arranging fault RRU is Unavailable.

Wherein, the adjustment work of supporting electrical tilt antenna angle has been controlled by RRU self, and adjusts RRU parameter is then completed by radio frequency resource dispatching control device, and is handed down to this critical RRU.

Step S107: the RRU taken in terminating flow process or searching other sectors is the most releasably to fault Transceiver uses.

When all searching the critical RRU less than the free time in other can search sector, i.e. it is believed that do not have properly Critical RRU and terminate flow process, it is preferred that allocated critical in other sectors can also be searched RRU, sees and whether belongs to the releasable critical RRU used to fault transceiver.

Embodiment two:

The radio frequency resource dispatch control method that the embodiment of the present invention two provides, its flow process is as it is shown on figure 3, wrap Include following steps:

Step S201: be periodically detected the duty of transceiver.

See step S101.

Step S202: when having detected that transceiver breaks down, it is judged that the transceiver broken down All RRU of association are the most unavailable.

If so, perform step S203, otherwise return and continue executing with step S201.

See step S102.

Step S203: RRU the most available free in sector belonging to detection fault transceiver.

See step S103.

If so, perform step S204, otherwise perform step S205.

Step S204: RRU idle in sector belonging to selecting uses to fault transceiver.

See step S104.

Step S205: belonging to detection fault transceiver, the channel of sector is the most occupied.

Unlike embodiment one, inquire about in other sectors whether there is the free time critical RRU it Before, belonging to detection fault transceiver, the channel of sector is the most occupied.When being judged as YES, then perform The step of the critical RRU of free time whether is there is in inquiring about other sectors.Otherwise return and continue executing with step S201。

That inquires about current all channels in sector belonging to fault transceiver in this step takies situation, by The baseband portion of BBU completes this function, reports radio frequency resource scheduling controlling dress by BP after specifically being added up Put, radio frequency resource dispatching control device after adding up, if it is confirmed that not all channel is the most occupied, but There is channel idle.Then the fault of explanation fault transceiver does not have influence on the work of whole sector, Can consider to stop this detection, wait the detection case of next cycle.

Step S206: whether there is the critical RRU of free time in inquiring about other sectors.Wherein, critical RRU is the RRU that can dispatch across sector pre-set.

See step S105.

If so, perform step S207, otherwise return and continue executing with step S208.

Step S207: critical RRU idle in selecting other sectors uses to fault transceiver.

See step S106.

Step S208: according to the channel occupancy situation of critical RRU allocated in other sectors, inquiry is No there is releasable critical RRU.

When finding the critical RRU that there is not the free time in other sectors, distribute in inquiring about other sectors The channel occupancy situation of critical RRU, according to the channel occupancy of critical RRU allocated in other sectors Situation, searches whether to there is releasable critical RRU；If so, step S209 is performed；Otherwise, perform Step S210.

Unoccupied channel quantity according to the allocated critical RRU in other sectors judges that this critical RRU is No for releasable RRU, when the unoccupied channel quantity of allocated critical RRU is setting quantity continuously The second detection cycle in when all exceeding the amount threshold of setting, determine that this critical RRU is releasable facing Boundary RRU.Preferably, the second detection cycle and the product setting quantity were less than for the first detection cycle.

In radio frequency resource dispatching control device this website of poll, all other comprises the fan distributing critical RRU District's channel occupancy situation, if super in having allocated critical RRU unoccupied channel N continuous the cycle Cross the threshold value set, it is believed that allocated critical RRU can discharge.

This step is reported transceiver channel occupancy situation by BP and calculates the channel occupancy of each sector Situation, base station main control unit opening timing device 2, take situation, if continuously for periodically aggregate channels The a certain sectors free channel number that N number of cycle BP reports exceedes threshold value, then show to deprive under this sector Critical RRU does not affect the normal work of this sector.Wherein, timer 2 cycle duration be multiplied by N must be little Cycle duration in cycle timer 1.

Preferably, it is contemplated that efficiency also takes into account the stability of system, and the threshold value of setting can be receipts Sender comprised channel maximum number, to ensure the robustness of whole system.

Step S209: releasable critical RRU is used to fault transceiver.

When find there is releasable critical RRU time, the resource of releasable critical RRU is released Put, dynamically adjust the RRU parameter of critical RRU and supporting electrical tilt antenna angle, in order to replace fault RRU, it is unavailable for arranging fault RRU simultaneously, with reference to step S106 during configuration.

RRU configuration parameter is switched and may be caused abnormal call drop phenomenon, but in view of the index of whole system With disaster tolerance, a small amount of abnormal call drop is to allow.

Step S210: compare the priority of sector belonging to fault transceiver and distributed critical RRU with all The priority of affiliated sector.

When there is not releasable critical RRU, it may be considered that from priority less than fault transceiver institute In the sector of the priority of the sector belonged to, select to have distributed critical RRU and use to fault transceiver.

Comprised by all other in this website of poll and distribute the sector priority of critical RRU, search excellent First level is less than sector belonging to fault RRU and comprises the sector distributing critical RRU.

In this step, the priority of each sector is preset by OMC, is handed down to base station as parameter, Poll work is performed by radio frequency resource dispatching control device, more has the right than low priority sector in high priority sector Limit takies critical RRU.

Step S211: whether there is the priority bag less than the priority of the sector belonging to fault transceiver Containing the sector distributing critical RRU.

If so, step S212 is performed；Otherwise terminate this flow process, return and continue executing with step S201.

Step S212: select less than the sector of the priority of the sector belonging to fault transceiver from priority Select and distribute critical RRU.

Preferably, all comprise distribute the low priority sector of critical RRU in choose priority minimum Sector.

Step S213: detection select critical RRU whether with BCCH (Broadcast Control Channel, BCCH) transceiver binding.

Priority is selected to face less than the distribution in the sector of the priority of the sector belonging to fault transceiver Boundary RRU, it is judged that whether the critical RRU of selection binds with the transceiver in affiliated sector.

Whether the critical RRU that particular exam selects binds with BCCH transceiver, if it is, perform Step 212, otherwise performs step 213.General base station is when carrying out transceiver and RRU binding, preferentially Select non-critical RRU to bind, therefore, once occur that critical RRU with BCCH transceiver is tied up Fixed situation, then illustrate that sector belonging to selected critical RRU is also faced with the situation of the shortage of RRU, It is inappropriate for now depriving its critical RRU, and sector belonging to the most selected critical RRU there will be fan The serious conditions that district interrupts.

In step S212 and step S213, all detection decision making algorithms are filled by radio frequency resource scheduling controlling Put execution.

If so, step S214 is performed；Otherwise perform step S215.

Step S214: the critical RRU bound with BCCH transceiver is deleted from alternative critical RRU Remove.

Return step S212 and be again less than other fans of sector priority belonging to fault transceiver in priority Selection in district has distributed critical RRU.

Step S215: distributed critical RRU to the use of fault transceiver by selected.

Distribute critical RRU for selected, discharged the resource of this critical RRU by force, dynamically adjust The RRU parameter of critical RRU and supporting electrical tilt antenna angle, in order to replace fault RRU, arranged simultaneously Fault RRU is unavailable, with reference to step S106 during configuration.

Step S212 achieves from priority preferential less than sector belonging to fault transceiver to step S214 In the sector of level, select to have distributed critical RRU and use to fault transceiver.
