Embodiment
For solving the problem that convergence rate is slow and systematic function is lower of the transmitting power adjustment of base station in prior art, the invention provides a kind of base station transmitting power collocation method and device, Centralized Controller collects the interception information that in administrative area, all base stations report, respectively based on the interception information that each base station reports, what filter out the pilot signal reception power that is more than or equal to the first thresholding and correspondence for corresponding base station is listened base station, obtain the first the selection result, and be listened base station configuration of transmit power according to being followed successively by each according to frequency of occurrences order from high to low in the first the selection result.
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is described in detail.
Consult shown in Fig. 1, in the embodiment of the present invention, as follows to the idiographic flow of base station transmitting power configuration:
Step 100: Centralized Controller collects the interception information that in administrative area, all base stations report, interception information at least comprises the Base Station Identification being listened base station, the pilot signal reception power of intercepting base station, wherein, intercept pilot signal that base station receives to be listened base station and to send.
Concrete, before Centralized Controller collects the interception information that in administrative area, all base stations report, Centralized Controller reads local each Base Station Identification preserved successively according to preset order, often read a Base Station Identification, corresponding base station is indicated to stop sending user data with maximum transmission power transmitting pilot signal as being listened base station intercepting the moment, and notifying other base stations except being listened base station in administrative area, intercepting moment closedown radio frequency and receiving the pilot signal and the measurement pilot signals Signal reception power that are listened Base Transmitter.
Concrete, Centralized Controller reads local each Base Station Identification preserved successively according to any one order from big to small or from small to large in cell ID, IP address or physical address, often read a Base Station Identification, corresponding base station is indicated to stop sending user data with maximum transmission power transmitting pilot signal as being listened base station intercepting the moment, wherein, Base Station Identification is any one in cell ID, Physical Cell Identifier or frequency point number.
Here base station will be intercepted notifying in administrative area that other base stations except being listened base station are called, being listened base station can be and the base station of intercepting the same frequency in base station or alien frequencies, but, due to intercept base station alien frequencies to be listened base station less to the interference intercepting base station, also less on the impact of transmitting power adjustment, therefore not as the content that the present invention discusses.
In addition, can also comprise the descending maximum transmit power value being listened base station in interception information, this descending maximum transmit power value being listened base station also can be preset at the descending maximum transmit power value being listened base station accordingly in Centralized Controller by the identified query being listened base station.
On the other hand, for universal mobile telecommunications system (Universal Mobile TelecommunicationsSystem, UMTS), the pilot signal reception power of then intercepting base station in interception information is Common Pilot Channel received signal code power CPICH (CommonPilot Channel Common Pilot Channel, Common Pilot Channel) RSCP (CommonPilot Channel Common Pilot Channel Reference SignalReceiving Power, Reference Signal Received Power), be listened the descending maximum transmit power value of base station for being listened base station down pilot transmit power CPICH TxPower.
Or

Step 110: Centralized Controller is respectively based on the interception information that each base station reports, and what filter out the pilot signal reception power that is more than or equal to the first thresholding and correspondence for corresponding base station is listened base station, obtains the first the selection result.
Concrete, base station in Centralized Controller administrative area is opened as being listened base station according to preset order successively, Centralized Controller have collected the interception information that in administrative area, all base stations report, and according to the interception information that each base station reports, what filter out that pilot signal reception power is greater than the first threshold value is listened base station, record the Base Station Identification of their correspondence, obtain the first the selection result.Wherein, the first thresholding refers to the target gate intercepting base station coverage edge.
Step 120: Centralized Controller is followed successively by each according to frequency of occurrences order from high to low and is listened base station configuration of transmit power in the first the selection result.
Concrete, it is corresponding that the first the selection result comprises each base station, and that sorts by pilot signal reception watt level is listened station list, and these pilot signal reception power being listened base station are more than or equal to the first thresholding.What Centralized Controller obtained according to the screening of all base stations is listened station list, to its frequency of occurrences according to Base Station Identification in descending order, is followed successively by each and is listened base station configuration of transmit power.
The frequency of occurrences of Base Station Identification is higher shows that the adjacent area of this base station is more, and disturbs larger with adjacent area, therefore this base station is preferentially carried out to the configuration of transmitting power.
Further, when Centralized Controller is after each in the first the selection result is listened base station configuration of transmit power, continue the interception information reported based on each base station, what filter out the pilot signal reception power that is less than the first thresholding and correspondence is listened base station, and do not listen to prewired be listened base station, obtain the second the selection result.

In addition, Centralized Controller can also process abnormal conditions, specifically comprises two kinds of situations:
One, when Centralized Controller determines that in administrative area, a certain base station does not listen to the interception information of peripheral base station, then directly the transmitting power of a certain base station of configuration is default maximum transmit power value.
They are two years old, Centralized Controller to the result of calculation of the transmitting power of a certain base station not in the interval of the preset transmitting power maximum in base station and transmitting power minimum value time, then the transmitting power of base station is configured to the transmitting power critical value preset, if namely the result of calculation of the transmitting power of this base station is lower than preset transmitting power minimum value, then the transmitting power of this base station is configured to preset transmitting power minimum value, if or the result of calculation of the transmitting power of this base station is higher than preset transmitting power maximum, then the transmitting power of this base station is configured to preset transmitting power maximum.
Consult shown in Fig. 2, the present invention, for LTE system, is described in detail to the idiographic flow of base station transmitting power configuration:
Step 201: Centralized Controller opens local Femto base station successively according to Cell ID size order, other Femto base stations are intercepted this base station.

Such as, may comprise in the interception information of base station A for base station B, base station C, the interception information of base station D, may comprise in the interception information of base station B for base station A, base station C, the interception information of base station D, by that analogy, base station C and base station D also reports interception information respectively.After base stations all in Centralized Controller administrative area are opened successively, Centralized Controller collects the interception information that in administrative area, all base stations report for peripheral base station.
Wherein, interception information comprises the Base Station Identification being listened base station, the pilot signal reception power of intercepting base station, is listened the descending maximum transmit power value of base station.
Step 203: Centralized Controller, according to the interception information of all Femto base stations, obtains transmitting power base station to be configured ordered list ConfigureFemto.
For the interception information that each base station reports, what Centralized Controller filtered out that pilot signal reception power is greater than the first threshold value is listened base station, records the Base Station Identification of their correspondence, obtains the selection result.
Further, Centralized Controller, according to the selection result of all base stations, sorts from high to low to the frequency of occurrences of Cell ID, obtains transmitting power base station to be configured ordered list ConfigureFemto.
Such as, base station B may be comprised in the interception information of base station A, base station C, the interception information of base station D, wherein, base station A is greater than the first threshold value for the pilot signal reception power of base station B and base station C, and therefore, the selection result that Centralized Controller obtains base station A is the Base Station Identification of base station B and base station C and the pilot signal reception power of correspondence thereof.Centralized Controller is according to base station A, base station B, and base station C, the selection result of base station D, the frequency of occurrences drawing Base Station Identification sequence is from high to low as transmitting power base station to be configured ordered list.
