Here, network equipment can be base station, base station controller, operation maintenance center etc.Usually, in mobile communication system, a base station comprises one or more community, and each community can use one or more frequency simultaneously.The method of the allocating cell frequency that the embodiment of the present invention provides implements respectively for each frequency of community, that is, when a base station comprises multiple community, when a community uses multiple frequency simultaneously, be configured respectively each frequency of each community.
Network equipment is when the interference level value determining that multiple frequencies that a community uses are subject to is greater than default interference level value, the frequency that the interference level value that is subject to is the highest can be stopped using, to avoid the plurality of frequency to stop using simultaneously, the small area jam that may cause.In reality, can according to the situation etc. of the business that the up-to-date traffic statistic result in community, community is using frequency quantity, each frequency is subject to interference level value, frequency are carrying, determine to stop using which or which frequency.Alternatively, before stopping using frequency, whether the carrier wave that assessment is left supports the capacity of community, after stopping using this frequency, is the frequency that this cell configuration is new again, to meet capacity requirement.Such as, if community is current using 4 frequencies, according to the traffic statistic result that community is up-to-date, estimation needs 3 frequencies can meet the telephone traffic demand of community, and the interference level value that this community has 2 frequencies to be subject at present is all greater than default interference level value, now, the frequency that the interference level value that is subject to is maximum can be stopped using, or stop there is no bearer service in 2 frequencies, or the priority of bearer service is lower, or the frequency that bearer traffic is minimum.Alternatively, be the frequency that this cell configuration is new again, to meet capacity requirement.Implementation method is not limited thereto, and visible product realizes and determines.
In reality, can according to network condition, Realization of Product, the method that the embodiment of the present invention provides is implemented on selection cycle ground.Such as: can select, every 1 minute, 5 minutes, 30 minutes or 2 hours etc. are carried out once, and the concrete cycle is not limited thereto, and is only example here.
Here, performance index value comprises multiple, because an object of the present invention is: determine the subdistrict frequency point that there is larger interference, so network equipment is when determining performance index value corresponding to subdistrict frequency point, selectable performance index value includes but not limited to following one or more: owing to disturbing the first ratio of number of dropped calls and the number of dropped calls caused, owing to disturb the second ratio of access failure number of times and the access failure number of times caused, owing to disturbing the incision frequency of failure caused and the 3rd ratio etc. cutting the frequency of failure.
Preferably, performance index value comprises: owing to disturbing the first ratio of number of dropped calls and the number of dropped calls caused;
Network equipment, according to this performance index value, is determined that the interference level value that frequency is subject to is greater than default interference level value, being comprised:
Network equipment determine frequency corresponding owing to disturbing the first ratio of the number of dropped calls that the causes number of dropped calls corresponding with this frequency to be greater than default interference cutting off rate threshold value time, determine that the interference level value that this frequency is subject to is greater than default interference level value.
Preferably, performance index value comprises: owing to disturbing the second ratio of access failure number of times and the access failure number of times caused;
Network equipment, according to this performance index value, is determined that the interference level value that frequency is subject to is greater than default interference level value, being comprised:

In reality, call drop, access failure and cut and unsuccessfully there is many reasons.For call drop, reason has multiple, includes but not limited to: the call drop etc. that the call drop disturbing call drop, the subscriber equipment caused to crash to cause, base station equipment fault cause; For access failure, reason has multiple, includes but not limited to: disturb the access failure etc. that weak access failure, the network congestion caused of the access failure caused, up and/or downstream signal intensity causes; For cutting unsuccessfully, reason also has multiple, includes but not limited to: the incision disturbing weak incision failure, the network congestion caused of failed, the up and/or downstream signal intensity of the incision that causes to cause unsuccessfully etc.Owing to the object of the invention is the subdistrict frequency point in order to determine to exist larger interference, so, when determining performance index value corresponding to frequency, determine owing to disturbing the call drop, access failure or the failed number of times of incision that cause.
The interference cutting off rate threshold value preset, interference access failure rate threshold value and interference incision mortality threshold value etc. can be arranged respectively according to network condition and Realization of Product, such as, can be set to 30%, 50% etc.
Further, when performance index value comprises: during owing to disturbing the first ratio of the number of dropped calls that causes and number of dropped calls, network equipment, after to determine to meet in following condition part or all of, according to performance index value, determines that the interference level value that frequency is subject to is greater than default interference level value:
The subscriber equipment trial access number of times that this frequency of condition one, this community is corresponding is greater than default access number of times threshold value;
4th ratio of the access number of success that the number of dropped calls that this frequency of condition two, this community is corresponding is corresponding with this frequency of this community is greater than default cutting off rate threshold value.
Arranging one of reason of above-mentioned two conditions is, after to meet in two conditions part or all of, just according to performance index value, determine that the interference level value that frequency is subject to is greater than default interference level value, avoid the use stopping subdistrict frequency point too frequently or irrelevantly.
Such as, attempting access number of times when the subscriber equipment that frequency is corresponding only has 2 times, all accesses successfully for 2 times, but in 2 times successfully access, has and cause call drop owing to disturbing 1 time, if the interference cutting off rate thresholding preset is 40%, then now will stop the use of this frequency.The number of times attempting accessing due to user is less, determine owing to disturbing the number of dropped calls that causes can not reflect with the first ratio of number of dropped calls is possible the real interference level that frequency is subject to.In reality, the access number of times threshold value preset that can arrange includes but not limited to: 50 times, 100 inferior, depending on network condition and Realization of Product.
One of reason of setting model two is, ensures only when the call drop situation determining that this frequency of this community is corresponding is more serious, just considers to stop using this frequency.The cutting off rate threshold value preset that can arrange includes but not limited to: 10%, 5% etc., depending on network condition and Realization of Product.
The performance index value corresponding when frequency comprises: during owing to disturbing the second ratio of the access failure number of times that causes and access failure number of times, also can be arranged on according to performance index value similarly, determine that interference level value that frequency is subject to is greater than the condition before default interference level value:

The performance index value corresponding when frequency comprises: during owing to disturbing the 3rd ratio with the incision frequency of failure of the incision frequency of failure that causes, also can be arranged on according to performance index value similarly, determine that interference level value that frequency is subject to is greater than the condition before default interference level value:
The user that this frequency of condition five, this community is corresponding attempts incision number of times and is greater than default incision number of times threshold value;
The 6th ratio that the incision frequency of failure that this frequency of condition six, this community the is corresponding user corresponding with this frequency of this community attempts cutting number of times is greater than default incision mortality threshold value.
The reason of setting model three to six and the similar of setting model one, two, the access failure rate threshold value preset that can arrange includes but not limited to: 5%, 10%, the incision mortality threshold value preset that can arrange includes but not limited to: 5%, 10%, specifically depending on network condition and Realization of Product.
Further, owing to disturbing the call drop that causes to comprise: the call drop caused due to uplink loss or the call drop caused due to descending step-out;
Network equipment determines the call drop because uplink loss causes according to following manner: network equipment, after receiving Radio Link Failure message, determines that corresponding call drop is the call drop because uplink loss causes;
Network equipment determines the call drop because descending step-out causes according to following manner: network equipment, receiving after the reason that comprises in the cell update message that subscriber equipment that call drop occurs sends is Radio Link Failure or wireless spread-spectrum technology fatal error, determines that corresponding call drop is the call drop because descending step-out causes.
Usually, when subscriber equipment uplink loss, the physical layer of the community own base station at this subscriber equipment place can report Radio Link Failure to be indicated to the upper strata of base station, and upper strata discharges the resource into this user equipment allocation.
Preferably, network equipment also comprises after stopping community use frequency:
Network equipment determines the frequency that the intensity transmitted of other communities that community receives is minimum, and allocating cell uses the frequency determined.
Alternatively, network equipment can make community own base station obtain transmitting of other communities of surrounding by the mode intercepted, the frequency that allocating cell uses the intensity transmitted of other communities received minimum.
The method that different system obtains peripheral cell signal strength signal intensity is different, and be described for GSM Home eNodeB and TD-SCDMA Home eNodeB below, the implementation method of other mobile communication standards is not limited thereto.
For gsm system Home eNodeB, base station, by intercepting peripheral cell, is obtained the received signal level RxLevel value of each community around, and is weighed the signal strength signal intensity of each community around by this value.
For TD-SCDMA system Home eNodeB, base station, by intercepting peripheral cell, is obtained the PCCPCHRSCP value of each community around, and is weighed the signal strength signal intensity of each community around by this value.
Alternatively, it is frequency in candidate's frequency of this community that the community that network equipment is determined receives the minimum frequency of the intensity transmitted of other communities.That is, network equipment selects a frequency from candidate's frequency of this community, and wherein, the transmit signal strength of other communities that this community receives on this frequency is minimum compared with other frequencies in candidate's frequency of this community.Candidate's frequency can be pre-configured according to requirement of Virtual network operator etc.
Preferably, network equipment stops community using frequency to comprise: network equipment forbids that new business is accessed by this frequency in community, and cuts off community ongoing business on this frequency.
Further, network equipment cuts off community ongoing business on this frequency, comprise: network equipment is being determined to need to stop community using this frequency, and when this frequency having in community the business of ongoing high priority, start timer, at timer expired and the business of high priority not at the end of, cut off community ongoing business on this frequency.
In order to improve network quality, avoid the operation of network side to cause cutting off of customer service as far as possible, when cutting off the business that community is carried out on frequency, first can determine whether this frequency exists high-priority service (for the definition of high-priority service, can depending on network condition and Realization of Product, such as, the business of definition conversation class and stream class is the business of high priority), if exist, then wait for default duration, exceeding this preset duration, and the business of high priority not at the end of, cut off community ongoing business on this frequency.
