Embodiment one
The method that the embodiment of the invention one provides a kind of adjacent area to optimize; Data and frequency sweep data through combining terminal to report are carried out adjacent area optimization; And providing adjacent area optimization suggestion, it can directly use in existing network work, has significantly reduced the time of engineer's test analysis; Improve the adjacent area optimizing efficiency, reduced the influence that mistake is optimized the adjacent area; As shown in Figure 1, this method may further comprise the steps:
In the embodiment of the invention, confirm main Serving cell through the data (TD-SCDMA test terminal or the GSM test terminal test data under IDLE (free time) state) of terminal to report, it has taken into full account the actual persistent district at terminal; And confirm that through the sweep check data that sweep generator measures it can not omit the strong signal cell that the terminal does not measure with reference to candidate adjacent.
Concrete; In order to realize the optimizing process of adjacent area; Then the interior adjacent area optimization of TD-SCDMA network test configurations comprises but is not limited to: TD-SCDMA test terminal, TD-SCANNER (sweep generator), GPS (Global Positioning System, global positioning system) and testing software; The interior adjacent area optimization of GSM network test configurations comprises but is not limited to: GSM test terminal, GSM-SCANNER, GPS and testing software; Dual system adjacent area optimization test configurations comprises but is not limited to: TD-SCDMA test terminal, GSM test terminal, TD-SCANNER, GPS and testing software.
Based on above-mentioned configuring condition; Main Serving cell and comprise: the reference candidate adjacent analysis of (1) TD-SCDMA network with reference to definite mode of candidate adjacent; The test data that test data and TD-SCANNER frequency sweep through related TD-SCDMA test terminal obtains; Obtaining resident sub-district, TD-SCDMA test terminal is main Serving cell, and other sub-district that the TD-SCANNER sweep measurement arrives is with reference to candidate adjacent; (2) the reference candidate adjacent analysis of GSM network; The test data that test data and GSM-SCANNER frequency sweep through related GSM test terminal obtains; Obtaining resident sub-district, GSM test terminal is main Serving cell, and other sub-district that the GSM-SCANNER sweep measurement arrives is with reference to candidate adjacent.
Concrete; According to confirming that in the signal strength signal intensity on each test point qualified test point comprises: according to selecting N the strongest signal of signal with reference to the signal strength signal intensity of candidate adjacent on current test point with reference to candidate adjacent; And obtain corresponding P-CCPCH (the Primary Common Control Physical Channel of this N signal; Primary Common Control Physical Channel) RSCP (Received Signal Code Power; Received signal code power) and P-CCPCH CIR (Carrier-To-Interference Ratio, Carrier interference ratio); When the corresponding P-CCPCH RSCP of N signal is not less than preset P-CCPCH RSCP thresholding, and N corresponding P-CCPCH CIR of signal be when being not less than preset P-CCPCH CIR thresholding, and then definite current test point is qualified test point; Otherwise, confirm that current test point is not qualified test point.
For example, during with reference to the test point 1-test point 10 on the candidate adjacent 1 corresponding test path, on test point 1, select N the strongest signal of signal, and obtain N signal corresponding P-CCPCH RSCP and P-CCPCH CIR; When the corresponding P-CCPCH RSCP of N signal is not less than preset P-CCPCH RSCP thresholding, and N corresponding P-CCPCH CIR of signal be when being not less than preset P-CCPCH CIR thresholding, and then definite test point 1 is qualified test point; Otherwise confirm that test point 1 is not qualified test point; By that analogy, can determine qualified test point in the test point 1-test point 10.
It should be noted that; Preset P-CCPCH RSCP thresholding and preset P-CCPCH CIR thresholding can be provided with according to actual conditions; Like preset P-CCPCH RSCP thresholding can be Rxlev (Received Signal Level for the GSM adjacent area; Received signal level) thresholding repeats no more to this.
According to the signal strength signal intensity on the current test point select N the strongest signal of signal specifically can for: obtain on the current test point signal that all are discharged to preceding N name (comprising the N name) in can detected signal; Wherein, N is the number thresholding of single-point cell signal, and actual is exactly the thresholding of pilot pollution, and it is too much unsuitable that it is used to be illustrated in the signal that searches on certain test point.
N the corresponding P-CCPCH RSCP of signal specifically includes but not limited to: the mean value of the P-CCPCH RSCP of N signal difference correspondence, the maximum of N the pairing P-CCPCH RSCP of signal, the minimum value of N the pairing P-CCPCH RSCP of signal; N the corresponding P-CCPCH CIR of signal includes but not limited to: the mean value of the P-CCPCH CIR of N signal difference correspondence, the maximum of N the pairing P-CCPCH CIR of signal, the minimum value of N the pairing P-CCPCH CIR of signal.
In the embodiment of the invention, in the process of confirming qualified test point, relate to the corresponding P-CCPCH CIR of N signal and the comparison procedure of preset P-CCPCH CIR thresholding, following situation be described based on this process need:
(1) P-CCPCH CIR is the P-CCPCH CIR with reference to candidate adjacent signal self, rather than the P-CCPCH CIR of main Serving cell;
(2) some test terminal or SCANNER can not directly report P-CCPCH CIR at present, and therefore the P-CCPCH RSCP that can only reporting neighboring cell and the ISCP [0] of adjacent area need ISCP [0] the calculating P-CCPCH CIR through P-CCPCH RSCP and adjacent area; Concrete computing formula is: P-CCPCH CIR (dB)=P-CCPCH RSCP (dB)-ISCP0 ］ (dB);
(3) if test terminal or SCANNER do not have the ISCP [0] of reporting neighboring cell; Then when confirming qualified test point; Directly according to selecting N the strongest signal of signal, and obtain the P-CCPCH RSCP of this N signal correspondence with reference to the signal strength signal intensity of candidate adjacent on current test point; When the corresponding P-CCPCH RSCP of N signal is not less than preset P-CCPCH RSCP thresholding, confirm directly that then current test point is qualified test point; Otherwise confirm that current test point is not qualified test point.
In the embodiment of the invention; Be specially the distance of the qualified test point of continuous appearance with reference to the corresponding mileage information (being chainage) of candidate adjacent; And if be single qualified test point, then mileage information is the distance between this test point and the previous drive test point.
It should be noted that the distance (being chainage) of qualified test point can not be simply between qualified test point the statistics mileage record add up then, consider but need mileage calculated to be placed under the original background of accomplishing the ground test path.
For example; Application scenarios sketch map as shown in Figure 2; Suppose that test point A, B, C, D, E, F are qualified test point; Then when obtaining with reference to the corresponding mileage information of candidate adjacent through qualified test point, its chainage is according to the mileage sum shown in Fig. 2 the first half, rather than according to the mileage sum shown in Fig. 2 the latter half.
Concrete; According to a plurality of with reference to the corresponding respectively mileage information of candidate adjacent from a plurality of with reference to selecting M to be that the corresponding adjacent area of main Serving cell comprises the candidate adjacent with reference to candidate adjacent: (for example obtain each according to a plurality of with reference to the corresponding respectively mileage information of candidate adjacent with reference to the mileage rank between the candidate adjacent; To each from long to short, carry out the mileage rank) with reference to the corresponding chainage of candidate adjacent; And from a plurality of be the corresponding adjacent area of main Serving cell with reference to the reference candidate adjacent of selecting the mileage rank the candidate adjacent before M (M is maximum adjacent area data, is the sum of the main Serving cell adjacent area that can have) and M.
It should be noted that; There is being the identical or mileage information of at least two mileage information corresponding to be under 0 the situation with reference to candidate adjacent; Then confirm the mileage rank according to following rule compositor, its priority is respectively from high to low: (1) qualified test point quantity from more to less; (2) from the near to the remote with reference to the distance between candidate adjacent base station, place and the base station, main Serving cell place; (3) with reference to the antenna of base station, candidate adjacent place towards and the antenna of base station, main Serving cell place towards between relation by over against to back to.
Concrete; There is being the identical or mileage information of at least two mileage information corresponding to be under 0 the situation, then obtaining at least two with reference to the mileage rank between the candidate adjacent: more at least two qualified test point quantity with reference to the candidate adjacent correspondence according to following mode with reference to candidate adjacent; When at least two qualified test point quantity with reference to the candidate adjacent correspondence are different, confirm that then the mileage rank of the reference candidate adjacent that qualified test point quantity is many is superior to the few reference candidate adjacent of qualified test point quantity; When at least two with reference to the corresponding qualified test point quantity of candidate adjacent when identical, then more at least two belong to the distance between the base station with reference to candidate adjacent base station, place and main Serving cell; When at least two with reference to the distance between base station, candidate adjacent place and the base station, main Serving cell place not simultaneously, confirm then that the mileage rank that belongs to the near reference candidate adjacent of distance between the base station with main Serving cell is superior to and main Serving cell belongs to the reference candidate adjacent of the distance between the base station; When at least two with reference to base station, candidate adjacent place when identical with distance between the base station, main Serving cell place, then more at least two antennas that belong to the base station with reference to candidate adjacent towards and the main Serving cell antenna that belongs to the base station towards between relation; Confirm with the antenna of base station, main Serving cell place towards relation for over against the mileage rank of reference candidate adjacent be superior to the antenna of base station, main Serving cell place towards relation for back to the reference candidate adjacent.
Concrete, the corresponding adjacent area of main Serving cell is optimized comprises: with the distance that main Serving cell belongs between the base station the corresponding adjacent area of main Serving cell is optimized according to base station, place, adjacent area; And/or, according to the antenna of base station, adjacent area place towards with the antenna of base station, main Serving cell place towards between relation the corresponding adjacent area of main Serving cell is optimized; And/or, according to adjacent area frequency points corresponding and scrambler and main Serving cell frequency points corresponding and scrambler the corresponding adjacent area of main Serving cell is optimized.
Optimization situation one, according to base station, adjacent area place and distance between the base station, main Serving cell place the corresponding adjacent area of main Serving cell is optimized and comprises: when belonging to distance between the base station greater than adjacent area isolation radius when base station, place, adjacent area with main Serving cell, then optimizing the adjacent area is not the adjacent area of main Serving cell correspondence; Otherwise optimizing the adjacent area is the corresponding adjacent area of main Serving cell.
Concrete, for whether setting up neighboring BS relationship between two sub-districts, its distance is an important consideration; If its distance is excessive, then there was the problem that covers probably in these two sub-districts, and should not set up neighboring BS relationship this moment, otherwise probably owing to the limited problem of up link, caused between these two sub-districts, switching the back call drop takes place; Based on this, can increase the condition threshold value " adjacent area isolates radius (km) " that an adjacent area is provided with in the embodiment of the invention; If the distance between certain base station, place, adjacent area and the base station, main Serving cell place is isolated radius greater than this adjacent area, then optimizing this adjacent area is not the corresponding adjacent area of main Serving cell; Otherwise optimizing this adjacent area is the corresponding adjacent area of main Serving cell.
Based on above-mentioned situation, in practical application, can optimize in the adjacent area and increase by two row in the tabulation: one of them is " distance ", the distance between base station, place, expression adjacent area and the main Serving cell base station of living in; Wherein another is " isolating relation ", and this isolation relation has two kinds of values: isolate radius if distance is less than or equal to the adjacent area, then its value is " isolating in the radius "; Otherwise its value is " it is outer to isolate radius ".
Optimization situation two, according to the antenna of base station, adjacent area place towards with the antenna of base station, main Serving cell place towards between relation the corresponding adjacent area of main Serving cell be optimized comprise: when the antenna of base station, place, adjacent area towards and the main Serving cell antenna that belongs to the base station towards between relation satisfy the preset direction angular region (the preset direction angular region can be selected according to actual needs; As 0 ° to 60 °) time, then optimizing the adjacent area is the corresponding adjacent area of main Serving cell; Otherwise optimizing the adjacent area is not the corresponding adjacent area of main Serving cell.
The antenna that it should be noted that base station, adjacent area place towards and the antenna of base station, main Serving cell place towards between the judgement of relation with based on geographical position adjacent section planning algorithm.
Optimization situation three, the corresponding adjacent area of main Serving cell is optimized with scrambler according to adjacent area frequency points corresponding and scrambler and main Serving cell frequency points corresponding and comprises: when the adjacent area frequency points corresponding different with main Serving cell frequency points corresponding; And the corresponding scrambler in the adjacent area scrambler corresponding with main Serving cell is not simultaneously, and the optimization adjacent area is the adjacent area of main Serving cell correspondence; Otherwise optimize the adjacent area is not the corresponding adjacent area of main Serving cell.
It should be noted that; Judgement explanation about the corresponding relation of frequency/scrambler and sub-district: if the adjacent area that the adjacent area is optimized in the tabulation all is in the base station table of user's importing, to inquire about with scrambler according to frequency to obtain; Then have two kinds of special circumstances to need to handle: (1) if according to a frequency/scrambler corresponding a plurality of sub-districts; Then need therefrom to take out the nearest sub-district of the main Serving cell of distance as candidate cell, and be filled in the optimization tabulation of adjacent area; (2) if according to certain frequency/scrambler is not found respective cell in base station table, then the adjacent area is optimized the relevant fields such as " base station titles " of candidate cell corresponding in the tabulation in capable and is filled out "-".
In the embodiment of the invention, the process that the adjacent area additions and deletions are judged, the adjacent area is added Rule of judgment and is: (1) is not configured to the adjacent area; (2) the P-CCPCH RSCP that signal is corresponding is not less than preset P-CCPCH RSCP thresholding, and the corresponding P-CCPCH CIR of signal is not less than preset P-CCPCH CIR thresholding; (3) the mileage rank is smaller or equal to adjacent area rank thresholding; (4) adjacent area isolates in the radius and (isolates radius if consider the adjacent area); Antenna towards relation over against (if consider antenna towards); Adjacent area deletion Rule of judgment is: (1) has been configured to the adjacent area; (2) demand is added the adjacent area and the configuring adjacent cell summation is greater than maximum adjacent area number, and the mileage rank is behind the number of maximum adjacent area; (3) adjacent area isolates radius outer (isolating radius if consider the adjacent area); (4) antenna towards relation back to (if consider antenna towards); (5) GSM neighboring interval BCCH (Broadcast Control Channel, BCCH) is identical or adjacent, and the adjacent area of mileage rank after.
Concrete; Based on above-mentioned interpolation Rule of judgment and deletion Rule of judgment; Obtaining the corresponding adjacent area of main Serving cell (specifically can be the adjacent area after optimizing) afterwards; If the adjacent area of selecting then can keep the adjacent area of selecting in Neighboring Cell List in the corresponding Neighboring Cell List of the main Serving cell of terminal to report; If the adjacent area of selecting in the corresponding Neighboring Cell List of the main Serving cell of terminal to report, then can not added in the adjacent area of selecting in Neighboring Cell List; If in the Neighboring Cell List of the main Serving cell correspondence of terminal to report the adjacent area that has disposed being arranged is not the adjacent area of selecting, then can in Neighboring Cell List, delete the adjacent area that has disposed.
It should be noted that; About whether being the judgement explanation of adjacent area; Then according to the neighboring BS relationship Data Source two kinds of determination methods are arranged: (1) is if the source is measuring terminals reporting neighboring cell data; If then certain frequency/scrambler appears at nearby region measurement the results list that the test terminal reports, then it is the adjacent area of current main Serving cell; (2) if the source is the outside neighboring BS relationship that imports, search in the relation table that then externally imports.
Through above-mentioned processing procedure, the result shows and application comprises: one, TD-SCDMA adjacent area adjustment record sheet, to optimize based on the drive test adjacent area, and it is as shown in table 1; Two, adjustment record sheet in GSM adjacent area is optimized based on the drive test adjacent area, and it is as shown in table 2.
