As shown in Figure 2, homogeneous-frequency adjacent-domain method for optimizing configuration of the present invention is described in further detail below:
Step 1: radio network controller (RNC) issues common frequency measurement to terminal, requires detected set can trigger the 1A event report, and terminal reports the 1A event report that comprises detected set after measuring.
In the embodiment of the invention, the trigger condition of 1A incident is configured to Active Set, supervision collection and detected set sub-district all can trigger the 1A event report.
Radio network controller issues common frequency measurement to terminal, requires to report the 1A incident, comprises the 1A incident that detected set triggers, and requires in the 1A event report simultaneously to comprise Active Set, monitor collection and detected set signal quality.
Particularly, corresponding cell can be provided with as follows in the measurement control:
Event 1A Triggering Condition:Detected set cells and monitored set cellsActive set, monitored set and detected set reporting quantities is:
Cell?synchronization?information?report?indicator：TRUE

Step 3: radio network controller is retrieved the detected set information record after verifying and is gathered, and filters out the detected set sub-district that signal quality reaches threshold requirement.
Specifically, radio network controller is to the detected set information after verifying, and carries out the record retrieval of detected set information and gathers, and preliminary detected set cell quality screening function is provided.
For each bar detected set record, retrieve according to the sign (ID) of the scrambler and the Active Set of detected set, report report to obtain Active Set and the demonstration of detected set quality by detected set.
According to Active Set that sets in advance and detected set signal quality absolute door limit value, detected set is reported the Active Set in the report and the quality of detected set, handle as the weak signal sub-district detected set sub-district less than corresponding absolute thresholding, further, can whether be not have leading cell scenario by Active Set cell signal quality determination.
For the detected set sub-district that surpasses corresponding absolute thresholding, carry out next step analysis.
Step 4: radio network controller according to the scrambler of this detected set sub-district, retrieves the sign with the corresponding sub-district of described scrambler to being higher than the detected set sub-district of absolute thresholding in the cell list of radio network controller.
Radio network controller is to being higher than the detected set sub-district of absolute thresholding, and the scrambler according in the information record of this detected set sub-district retrieves the sign with the corresponding sub-district of cell scrambling in the cell list of radio network controller.
Preferably, in the 1A event report that can report according to detected set to the recorded information of Active Set, report Active Set record in the report for detected set, in the geographical topology figure of the cell list of radio network controller, directly indicate the Active Set sub-district according to Active Set cell ID (Cell Id), the Active Set sub-district that this is labeled out is not to leak the adjacent area of joining.
Step 5: the detected set sub-district that retrieval marks is analyzed the adjacent area that obtains leak joining.This step has two kinds of implementations:
A) retrieve corresponding cell ID according to the scrambler of this detected set sub-district after, carry out the geographical topology analysis, go out to leak the adjacent area of joining according to geographical position estimation.It comprises following two steps:
Steps A 51: after the scrambler corresponding district sign according to the detected set sub-district that is higher than absolute thresholding, in geographical topology figure, indicate the sub-district that all use this scrambler.
The geographical position of sub-district determines that this is existing technology by the latitude and longitude of base station information acquisition in the engineering parameter, and the present invention is not described in detail.
Steps A 52: in the detected set sub-district in the geographical topology analysis chart that indicates according to scrambler, calculate the detected set sub-district nearest apart from geographical position, sub-district, terminal place, as miss-configured neighboring cells, and corresponding cell ID (ID) configuration parameter is configured in the neighbor cell configuration tabulation.
B) retrieve corresponding cell ID according to the scrambler of this detected set sub-district after, the data of the 1A event report that reports according to detected set, intellectual analysis is carried out in the sub-district of the sign that retrieval is come out, and goes out miss-configured neighboring cells according to signal quality estimation.
Step B51: the data of the 1A event report that reports according to detected set, intellectual analysis is carried out in the sub-district of the sign that retrieval is come out, detected set signal quality stepping, the adjacent area reliability difference of each grade correspondence, reliability is come index by a weight;
Step B52: the weight as a result of actual optimization is defined as the adjacent area of Lou joining greater than the sub-district of certain value, is configured in the neighbor cell configuration tabulation.
For example, the detected set signal quality is divided into 5 grades, the adjacent area reliability difference of each grade correspondence, reliability is come index by a weight (Credit).Classification of 5 grades of signal strength signal intensities (Range) and weight (Credit) can dispose.
Can import first level definition and be Ec/Io more than or equal to-6dB, weight is 4; The second level be defined as Ec/Io more than or equal to-8dB less than-6dB, weight is 3; The third level be defined as Ec/Io more than or equal to-10dB less than-8dB, weight is 2; The fourth stage be defined as Ec/Io more than or equal to-12dB less than-10dB, weight is 1; Level V is defined as Ec/Io less than-12dB, and weight is 0.Can obtain the weight of miss-configured neighboring cells like this by this algorithm, can be defined as the adjacent area of Lou joining greater than the sub-district of certain value, be configured in the neighbor cell configuration tabulation according to the weight as a result of actual optimization.
Homogeneous-frequency adjacent-domain method for optimizing configuration of the present invention is by using the network retrieval function, obtain neighboring interval by traffic measurement and switch frequency and success rate, for not taking place, the low neighbor cell configuration of switching or handover success rate carried out geoanalysis, whether the leakage of affirmation adjacent area is joined and is existed, automatically obtain the information of homogeneous-frequency adjacent-domain, carry out homogeneous-frequency adjacent-domain and leak the optimization of joining, it reduces the adjacent area and leaks the optimization cost of joining, improve the adjacent area and leak the optimization range of joining, improve the adjacent area and leak the efficient of joining optimization work.
