Below in conjunction with the accompanying drawing in the present invention, the technical scheme in the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment mono-
The embodiment of the present invention one provides a kind of method of Neighborhood Optimization, by the data in conjunction with terminal to report and frequency sweep data, carry out Neighborhood Optimization, and provide Neighborhood Optimization suggestion, it can directly use in existing network work, greatly reduced the time of engineer's test analysis, improve the efficiency of Neighborhood Optimization, reduced the impact of mistake on Neighborhood Optimization; As shown in Figure 1, the method comprises the following steps:
Step 101, determines corresponding a plurality of with reference to candidate adjacent in main Serving cell and this main Serving cell.
In the embodiment of the present invention, by the test data under data (TD-SCDMA test terminal or GSM test terminal are idle at the IDLE() state of terminal to report) determine main Serving cell, it has taken into full account the actual persistent district of terminal; And the sweep check data that measure by sweep generator are definite with reference to candidate adjacent, and it can not omit the strong signal cell that terminal does not measure.
Concrete, in order to realize the optimizing process of adjacent area, Neighborhood Optimization test configurations comprises but is not limited in TD-SCDMA network: TD-SCDMA test terminal, TD-SCANNER(sweep generator), GPS(Global Positioning System, global positioning system) and testing software; In GSM network, Neighborhood Optimization test configurations comprises but is not limited to: GSM test terminal, GSM-SCANNER, GPSHe testing software; Dual system Neighborhood Optimization test configurations comprises but is not limited to: TD-SCDMA test terminal, GSM test terminal, TD-SCANNER, GPSHe testing software.
Based on above-mentioned configuring condition, main Serving cell and comprising with reference to definite mode of candidate adjacent: the reference candidate adjacent of (1) TD-SCDMA network is analyzed, the test data that test data and TD-SCANNER frequency sweep by associated TD-SCDMA test terminal obtains, obtain resident Wei Zhu Serving cell, community, TD-SCDMA test terminal, other community that TD-SCANNER sweep measurement arrives is with reference to candidate adjacent; (2) the reference candidate adjacent of GSM network is analyzed, the test data that test data and GSM-SCANNER frequency sweep by associated GSM test terminal obtains, obtain resident Wei Zhu Serving cell, community, GSM test terminal, other community that GSM-SCANNER sweep measurement arrives is with reference to candidate adjacent.
Step 102, according to reference to candidate adjacent the signal strength signal intensity in each test point determine qualified test point; Wherein, for each with reference to candidate adjacent, it all can be corresponding to a plurality of test points on test path (be corresponding a plurality of test points in GPS moving process, GPS moving process be test path), and need to from a plurality of test points, determine qualified test point.
Concrete, according to reference to candidate adjacent the signal strength signal intensity in each test point determine that qualified test point comprises: according to reference to candidate adjacent the signal strength signal intensity in current test point select N the strongest signal of signal, and obtain the P-CCPCH(Primary Common Control Physical Channel that this N signal is corresponding, 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 N P-CCPCH RSCP corresponding to signal is not less than default P-CCPCH RSCP thresholding, and N P-CCPCH CIR corresponding to signal be while being not less than default P-CCPCH CIR thresholding, and definite current test point is qualified test point; Otherwise, determine that current test point is not qualified test point.
For example, during with reference to test point 1-test point 10 on the corresponding test path in candidate adjacent 1, in test point 1, select N the signal that signal is the strongest, and obtain N P-CCPCH RSCP and the P-CCPCH CIR that signal is corresponding; When N P-CCPCH RSCP corresponding to signal is not less than default P-CCPCH RSCP thresholding, and N P-CCPCH CIR corresponding to signal be while being not less than default P-CCPCH CIR thresholding, and definite test point 1 is qualified test point; Otherwise determine that test point 1 is not qualified test point; By that analogy, can determine qualified test point in test point 1-test point 10.
It should be noted that, default P-CCPCH RSCP thresholding and default P-CCPCH CIR thresholding can arrange according to actual conditions, if default P-CCPCH RSCP thresholding can be Rxlev(Received Signal Level for GSM adjacent area, received signal level) thresholding, repeats no more this.
According to the signal strength signal intensity in current test point, select N the strongest signal of signal to be specifically as follows: the signal that obtains being discharged in all signals that can detect in current test point front N name (comprising N name); 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 for being illustrated in the signal searching in certain test point.
N P-CCPCH RSCP corresponding to signal specifically includes but not limited to: N signal distinguished the mean value of corresponding P-CCPCH RSCP, the maximum of N the corresponding P-CCPCH RSCP of signal, the minimum value of N the corresponding P-CCPCH RSCP of signal; N P-CCPCH CIR corresponding to signal includes but not limited to: N signal distinguished the mean value of corresponding P-CCPCH CIR, the maximum of N the corresponding P-CCPCH CIR of signal, the minimum value of N the corresponding P-CCPCH CIR of signal.
In the embodiment of the present invention, in determining the process of qualified test point, relate to P-CCPCH CIR that N signal is corresponding and the comparison procedure of default P-CCPCH CIR thresholding, based on this process need, be described as follows situation:
(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, P-CCPCH RSCP that can only reporting neighboring cell and the ISCP[0 of adjacent area], therefore need to be by the ISCP[0 of P-CCPCH RSCP and adjacent area] P-CCPCH CIR calculated; Specific formula for calculation 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], when determining qualified test point, direct according to N the strongest signal of the selection signal of the signal strength signal intensity in current test point with reference to candidate adjacent, and obtain the P-CCPCH RSCP that this N signal is corresponding; When N P-CCPCH RSCP corresponding to signal is not less than default P-CCPCH RSCP thresholding, directly determine that current test point is qualified test point; Otherwise determine that current test point is not qualified test point.
Step 103, obtains with reference to mileage information corresponding to candidate adjacent according to qualified test point.
In the embodiment of the present invention, with reference to mileage information corresponding to candidate adjacent (being chainage), be specially the distance of the qualified test point of continuous appearance, and single qualified test point if, mileage information is the distance between this test point and previous drive test point.
The distance (being chainage) that it should be noted that qualified test point can not be added up mileage record simply and then be added up between qualified test point, but mileage calculation need to be placed under the background that originally completes ground test path, considers.
For example, application scenarios schematic diagram as shown in Figure 2, suppose that test point A, B, C, D, E, F are qualified test point, when obtaining with reference to mileage information corresponding to candidate adjacent by 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.
Step 104, according to a plurality of with reference to candidate adjacent respectively corresponding mileage information from a plurality of with reference to selecting M candidate adjacent with reference to adjacent area corresponding to Wei Zhu Serving cell, candidate adjacent.
Concrete, according to a plurality of with reference to candidate adjacent respectively corresponding mileage information from a plurality of with reference to selecting M to comprise with reference to adjacent area corresponding to Wei Zhu Serving cell, candidate adjacent candidate adjacent: according to a plurality of with reference to candidate adjacent respectively corresponding mileage information with reference to the mileage rank between candidate adjacent (for example obtain each, to each with reference to chainage corresponding to candidate adjacent from long to short, carry out mileage rank); And from a plurality of with reference to selecting mileage rank candidate adjacent, at M(M, be maximum adjacent area data, be the sum of the adjacent area that can have, main Serving cell) and M before adjacent area corresponding to Wei Zhu Serving cell, reference candidate adjacent.
It should be noted that, in the situation that there are at least two, with reference to mileage information corresponding to candidate adjacent, identical or mileage information is 0, according to following rule compositor, determine mileage rank, its priority is respectively from high to low: (1) qualified test point quantity from more to less; (2) with reference to the distance between base station, place, Yu Zhu Serving cell, base station, place, candidate adjacent from the near to the remote; (3) with reference to the antenna of base station, place, candidate adjacent towards and the antenna of base station, place, main Serving cell towards between relation by over against to back to.
Concrete, in the situation that there are at least two, with reference to mileage information corresponding to candidate adjacent, identical or mileage information is 0, obtains in the following manner at least two with reference to the mileage rank between candidate adjacent: more at least two with reference to qualified test point quantity corresponding to candidate adjacent; When at least two when different with reference to qualified test point quantity corresponding to candidate adjacent, determine that the mileage rank of the reference candidate adjacent that qualified test point quantity is many is better than the reference candidate adjacent that qualified test point quantity is few; When at least two when identical with reference to qualified test point quantity corresponding to candidate adjacent, more at least two with reference to the distance between base station, place, Yu Zhu Serving cell, base station, place, candidate adjacent; When at least two when different with reference to distance between base station, place, Yu Zhu Serving cell, base station, place, candidate adjacent, determine and base station, place, main Serving cell between the mileage rank of reference candidate adjacent of near distance be better than and base station, place, main Serving cell between the reference candidate adjacent of distance; When at least two when identical with reference to the distance between base station, place, Yu Zhu Serving cell, base station, place, candidate adjacent, more at least two antennas with reference to base station, place, candidate adjacent towards and the antenna of base station, place, main Serving cell towards between relation; Determine antenna with base station, place, main Serving cell towards pass, be over against the mileage rank of reference candidate adjacent be better than antenna with base station, place, main Serving cell towards pass, be back to reference candidate adjacent.
Step 105, the adjacent area corresponding to main Serving cell is optimized.
Concrete, adjacent area corresponding to main Serving cell is optimized and comprised: according to the distance between base station, place, Yu Zhu Serving cell, base station, place, adjacent area, adjacent area corresponding to main Serving cell is optimized; And/or, according to the antenna of base station, place, adjacent area towards the antenna with base station, place, main Serving cell towards between relation adjacent area corresponding to main Serving cell is optimized; And/or, according to frequency corresponding to adjacent area and corresponding frequency and the scrambler of scrambler and main Serving cell, adjacent area corresponding to main Serving cell is optimized.
Optimization situation one, according to the distance between base station, place, Yu Zhu Serving cell, base station, place, adjacent area, adjacent area corresponding to main Serving cell is optimized and comprised: when the distance between base station, place, Yu Zhu Serving cell, base station, place, adjacent area is greater than adjacent area isolation radius, optimize adjacent area corresponding to Bu Shizhu Serving cell, adjacent area; Otherwise, optimize adjacent area corresponding to Shi Zhu Serving cell, adjacent area.
Concrete, for whether setting up neighboring BS relationship between Liang Ge community, its distance is an important Consideration; If its distance is excessive, probably there is the problem covering in Ze Zheliangge community, now should not set up neighboring BS relationship, otherwise probably due to the limited problem of up link, cause the rear call drop that occurs of switching between Zhe Liangge community; Based on this, in the embodiment of the present invention, can increase the condition threshold value " adjacent area isolation radius (km) " that an adjacent area arranges; If the distance between certain base station, place, Yu Zhu Serving cell, base station, place, adjacent area is greater than this adjacent area isolation radius, optimize adjacent area corresponding to Bu Shizhu Serving cell, this adjacent area; Otherwise, optimize adjacent area corresponding to Shi Zhu Serving cell, this adjacent area.
Based on above-mentioned situation, in actual applications, can in Neighborhood Optimization list, increase by two row: one of them is " distance ", represent the distance between base station of living in, He Zhu Serving cell, base station, place, adjacent area; Wherein another is " isolated relation ", and this isolated relation has two kinds of values: if distance is less than or equal to adjacent area isolation radius, its value is " in isolation radius "; Otherwise its value is " isolation radius is outer ".
Optimization situation two, according to the antenna of base station, place, adjacent area towards the antenna with base station, place, main Serving cell towards between relation adjacent area corresponding to main Serving cell is optimized and comprised: when the antenna of base station, place, adjacent area towards and the antenna of base station, place, main Serving cell towards between relation meet preset direction angular region (preset direction angular region can be selected according to actual needs, as 0 ° to 60 °) time, optimize adjacent area corresponding to Shi Zhu Serving cell, adjacent area; Otherwise, optimize adjacent area corresponding to Bu Shizhu Serving cell, adjacent area.
The antenna that it should be noted that base station, place, adjacent area towards and the antenna of base station, place, main Serving cell towards between the judgement of relation with based on geographical position adjacent section planning algorithm.
Optimization situation three, according to frequency corresponding to adjacent area, adjacent area corresponding to main Serving cell is optimized and comprised with scrambler with frequency corresponding to scrambler and main Serving cell: when the frequency that frequency corresponding to adjacent area is corresponding from main Serving cell different, and when the scrambler that scrambler corresponding to adjacent area is corresponding from main Serving cell is different, optimize adjacent area corresponding to Shi Zhu Serving cell, adjacent area; Otherwise optimize adjacent area corresponding to Bu Shizhu Serving cell, adjacent area.
It should be noted that, judgement explanation about the corresponding relation of frequency/scrambler and community: if the adjacent area in Neighborhood Optimization list is all to inquire about and obtain in the base station table importing user according to frequency and scrambler, have two kinds of special circumstances to need to process: (1) if according to frequency/scrambler correspondence a plurality of communities, need therefrom to take out nearest community, the main Serving cell of distance as candidate cell, and be filled in Neighborhood Optimization list; (2), if frequency/scrambler is not found in base station table according to certain respective cell, in Neighborhood Optimization list, the corresponding candidate cell fields such as relevant " base station titles " in capable is filled out "-".
In the embodiment of the present invention, the process of adjacent area additions and deletions judgement, adjacent area is added Rule of judgment and is: (1) is not configured to adjacent area; (2) the P-CCPCH RSCP that signal is corresponding is not less than default P-CCPCH RSCP thresholding, and P-CCPCH CIR corresponding to signal is not less than default P-CCPCH CIR thresholding; (3) mileage rank is less than or equal to adjacent area rank thresholding; (4) (if considering adjacent area isolation radius) in adjacent area isolation radius; Antenna towards relation over against (if consider antenna towards); Rule of judgment is deleted in adjacent area: (1) has been configured to adjacent area; (2) demand interpolation He Yi configuring adjacent cell, adjacent area summation is greater than maximum adjacent area number, and mileage rank is after the number of maximum adjacent area; (3) adjacent area isolation radius outer (if considering adjacent area isolation radius); (4) antenna towards relation back to (if consider antenna towards); (5) GSM neighboring interval BCCH(Broadcast Control Channel, Broadcast Control Channel) 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 adjacent area corresponding to main Serving cell (being specifically as follows the adjacent area after optimization) afterwards, if the adjacent area of selecting, in Neighboring Cell List corresponding to the main Serving cell of terminal to report, can keep the adjacent area of selecting in Neighboring Cell List; If the adjacent area of selecting, not in Neighboring Cell List corresponding to the main Serving cell of terminal to report, can be added in the adjacent area of selecting in Neighboring Cell List; If having the adjacent area having configured in Neighboring Cell List corresponding to the main Serving cell of terminal to report is not the adjacent area of selecting, can in Neighboring Cell List, delete the adjacent area having configured.
It should be noted that, about whether being the judgement explanation of adjacent area, according to neighboring BS relationship Data Source, there are two kinds of determination methods: (1) is if source is measuring terminals reporting neighboring cell data, if certain frequency/scrambler appears at nearby region measurement the results list that test terminal reports, it is the adjacent area of current main Serving cell; (2) if source is the outside neighboring BS relationship that imports, in the relation table externally importing, search.
By above-mentioned processing procedure, result shows and application comprises: one, record sheet is adjusted in TD-SCDMA adjacent area, and based on drive test Neighborhood Optimization, it is as shown in table 1; Two, record sheet is adjusted in GSM adjacent area, and based on drive test Neighborhood Optimization, it is as shown in table 2.
