Specific embodiment
Technical solution of the present invention is further described in detail with reference to the accompanying drawings and specific embodiments of the specification.
Embodiment of the method one:
The present embodiment provides a kind of miss-configured neighboring cells processing methods, which comprises
Obtaining step S110: in the measurement report formed when residing in main plot from user equipment, obtaining user equipment can The first community of the first community searched identifies;The first community is the cell other than the main plot;
Judgment step S120: according to the measurement report, judge whether the first community is to meet default switching condition Cell;
It determines step S130: first community mark and the second community mark of preconfigured adjacent area is compared It is right, when first community mark does not include that the interior and described first community is the default switching item of satisfaction in second community mark When the cell of part, it is determined that the first community is the miss-configured neighboring cells of the main plot.
User equipment specifically may include the measuring control information that mobile phone, mobile phone would generally receive base station transmission;And according to institute Measuring control information is stated to measure received signal;Specifically such as, the electricity of the signal of the base station transmission of main plot is received Flat measurement, measures the level of the signal of the transmission of the cell around the main plot.And by way of measurement report Measurement result is returned into base station.If the signal quality parameter that usual user equipment A has measured main plot signal is smaller than first When the signal quality parameter of area's signal is weak, it is believed that if current user equipment is switched to adjacent area and can obtain better signal quality.This When, it will be considered that the adjacent area is the adjacent area for meeting switching condition, and the cell ID of the adjacent area can be documented in measurement report and be sent out Give base station.The cell ID may include (Physical Cell Identifier, PCI).
The main plot is the cell that user equipment A is currently resident;The main plot signal is what the main plot was sent Signal.The signal quality parameter may include the level intensity of signal.The first community signal is first community transmission Signal.
By the small of PCI of the user equipment into the measurement report that base station reports and the preconfigured adjacent area for being used to reconfigure Area mark PCI is compared, and can determine whether that adjacent area is not configured to the adjacent area column that can be used for reconfiguring of base station In table, in this way, after data processing being carried out using electronic equipments such as computers, fast, leakage is accurately determined Cell is based on drive test data based on staff and pays a return visit point-to-point analysis relative to existing, have it is high-efficient, avoid artificial point The low problem of accuracy caused by analysing, simultaneously also has the advantages that at low cost.
Further, the miss-configured neighboring cells include apolegamy adjacent area and essential miss-configured neighboring cells;
As shown in Fig. 2, the method also includes:
Step S140: drive test obtains the sample point data of the main plot;Wherein, the sample point data includes second small The signal quality parameter of area's signal: the second community signal is the signal sent by second community;The second community is institute State the cell other than main plot;
Step S150: according to the signal quality parameter of the second community, determine that whether described second community master be small The adjacent area in area, the adjacent area are the first adjacent area;It is full of herein and is named as first community in order to illustrate by the adjacent area of main plot, not There is sequencing or refers in particular to the consciousness in generation;
The step S130 can include:
When the miss-configured neighboring cells be first adjacent area when, determine the miss-configured neighboring cells be must matched adjacent zone;
When the miss-configured neighboring cells are not first adjacent area, determine the miss-configured neighboring cells for apolegamy adjacent area.
It is described must matched adjacent zone be the cell that must configure of the main plot, otherwise will lead to a large amount of user equipment and carrying out When cell switches, the better adjacent area of service quality can not be switched to.
In the present embodiment in order to distinguish must matched adjacent zone and apolegamy adjacent area, also introduce and sampling location carried out to main plot Drive test, and according to drive test result determine whether must matched adjacent zone technical solution, usually during subsequent operation, if the adjacent area For must matched adjacent zone, then directly by it is described must matched adjacent zone be added in the neighboring cell list of base station, it is convenient after the cell of user equipment cut It changes.It, may be a in view of the adjacent area for including in the neighboring cell list of current main plot when the miss-configured neighboring cells are apolegamy adjacent area Number etc. is because usually determining whether to for being added in neighboring cell list the apolegamy adjacent area.
Specifically how to determine whether the second community detected in the sampled data of sampling location detection is described first Adjacent area, several optional ways of step S150 presented below:
Mode one:
The step S150 can include:
The sample point data is analyzed, determines and detects the signal matter of the second community signal in sampling location Measure parameter;Signal quality parameter herein includes the level intensity of signal;
Compare the signal quality parameter and preset signals quality, forms the first comparison result;It is specific to believe as described in relatively The size relation of number mass parameter and the preset signals quality, specifically such as compares the level intensity of the second community signal of measurement With the size between predetermined level intensity;
According to first comparison result, determine that the adjacent area is first adjacent area.
It in some embodiments, can be directly when the signal quality parameter be not less than the preset signals quality, really Fixed corresponding second community must matched adjacent zone for described in;But in order to further increase accuracy, the method in the present embodiment Further include: the signal quality parameter is counted not less than the corresponding sample point data of the preset signals quality;When described When counting greater than default value, determine that the second community is first adjacent area;And when described count is not more than default value When, determine that the second community is the cell other than first adjacent area.
Specifically such as, drive test sampling currently is carried out to 50 sampling locations of main plot, finds the signal quality parameter of adjacent area A Level intensity in the sample point data of multiple sampling locations is greater than predetermined level intensity, and such as larger than -110dbm can be direct Think that the adjacent area must matched adjacent zone described in being;It can also be and further count the number that sampling site data are greater than predetermined level intensity, when When the number is greater than the default value, just think that the second community is first adjacent area.If the default value is 15, Then can be must when level intensity 15 sampling locations when being all larger than predetermined level intensity, just think the second community For first adjacent area.Above-mentioned predetermined level intensity is one of described preset signals quality, and the level intensity is letter One of number mass parameter.
The sample point data can be the statistics in multiple repairing weld data.Such as 10 times are carried out 50 sampling locations to adopt Sample specifically can be to signal quality parameter to determine the stability of the second community signal not less than the default letter Number value come can the number of sample point data counted, when the number is greater than preset times, at such as 7 times, it is determined that this Two cells are first adjacent area.
Mode two:
The step S150 can include:
The sample point data is analyzed, determines and detects the signal quality ginseng of second community signal in sampling location Number;Signal quality to each second community in each sampling location is joined, and carries out integral assignment by preset function;To each described The integral of 2 cell points is accumulated, and is ranked up to accumulation results;Determine that the second community is the according to the sequence One adjacent area.
Specifically such as, there are 50 sampled points in current main plot, and a drive test sampling will form 50 sample point datas, Ge Gelin The signal quality parameter in area carries out integral assignment.Specifically such as in sampling location A, the signal of the signal quality parameter characterization of cell A Quality is better, then integrates highest;Each second is come in the signal quality of sampling location B, the signal quality parameter characterization of cell A Second in the signal quality parameter of cell, then integral is only second to top.Integral by cell A 50 sampling locations again It is accumulated, and accumulation results is ranked up, and final foundation ranking results determine whether the second community is described First adjacent area.
If the signal quality parameter is level intensity;Then level intensity value is bigger, then integrates higher;The accumulation knot of integral Fruit it is higher, then the second community be the adjacent area even closer with the adjacent area incidence relation of the main plot a possibility that it is bigger.
At this time can be by sequence, several forward second communities of selected and sorted are as first adjacent area, or selection Accumulation is higher than several second communities of default score value as first adjacent area.
Mode three:
The step S150 can include:
The main plot is measured at a distance from each second community;
When the distance is not more than distance threshold, determine that the second community is first adjacent area.
The distance of main plot and the second cell can be by the base station of main plot between the base station of the second cell Distance;If the distance between two base stations are excessive, it is clear that user equipment is switched to the probability of the second community from main serving cell It is smaller.In specific implementation the distance threshold can according to the radius of society of the main serving cell and the second community come It determines.If the radius of all cells is 400 meters specifically in current network, then at this point, the distance threshold is believed that 800 meters, If the two cells are not all adjacent area in geographic range more than 800 meters, it is clear that there is no directly cut from main plot Change to the situation of the second community.
Method described in the present embodiment, the measurement report reported first by UE is easy to define leakage cell, then By drive test data, determine which be must matched adjacent zone and apolegamy adjacent area, for it is subsequent whether in the adjacent area table of base station add leakage It provides convenience with cell, has the advantages that realize relative to existing method simple and efficient.

This example plays back to analyze and search the adjacent area LTE leakage method not only labor intensive time for existing drive test data, But also the cell and possible error in judgement of adjacent area leakage can not be accurately found out, it is reported using analyzing in measurement report Cell and sampled point in persistent signal intensity compared with strong and apart from the closer cell of main serving cell, pass through certain screening Condition and marking sort to search the cell of adjacent area leakage.
This example includes 2 core contents, and one is search adjacent area leakage cell based on the A3 event in measurement report; One is being assessed by certain screening conditions and marking mechanism the adjacent cell measured, sees if there is and belong to adjacent area leakage The cell matched.The A3 event is the event that adjacent area service quality is higher than threshold value.
Step 1: A3 event in analysis signaling, reports A3 affair MR (Measurement Report, MR) and carries out Decoding obtains the neighboring BS information that terminal reports, and is compared automatically with the neighboring BS information issued in measurement control, obtains adjacent area leakage With information;
Step 2: data and frequency sweep data in fusion MR report, carry out time, space and signal to collected adjacent area Reasonable adjacent area is assessed in three dimension weightings of intensity, is compared neighbor cell configuration information, is positioned miss-configured neighboring cells;
Step 3: output optimization base station neighboring cell list.
The first step can include: adjacent area leakage cell principle and process are searched based on the A3 event in measurement report:
1.1LTE totality switching flow:
The lateral user equipment of network sends wireless resource control connection reconfiguration message RRC Connection Reconfiguration is meeting comprising the parameter configuration that source cell neighboring cell list and handover trigger and measurement report require After switch decision condition, from UE to eNodeB reporting measurement reports, is decided whether to execute switching by eNodeB, pass through RRC Connection Reconfiguration sends switching command to UE, and UE completes to feed back RRC to eNodeB after configuring Connection Reconfiguration Complete message completes switching.The eNodeB is one kind of base station, is evolution Type base station.
LTE switching can include:
Network side issues RRC Connection Reconfiguration, includes source cell neighboring cell list and switching touching The parameter configuration that hair and measurement report require.
After meeting measurement thresholding, from UE to eNodeB reporting measurement reports, the measured value comprising source cell, Target cell PCI and measured value.
It after meeting switching condition, is decided whether to execute switching by eNodeB, passes through RRC Connection Reconfiguration sends switching command to UE, includes switching target small area PCI in message.
UE completes RRC Connection to eNodeB feedback wireless heterogeneous networks punching configuration after the completion of switching Reconfiguration Complete message completes switching.
Base station meeting sending measuring control message carries the neighboring BS information of cell to mobile phone, the inside in LTE signaling.Terminal reports It can be reported according to A3 event judgment principle in measurement report, the cell reported is not influenced by adjacent area in measurement control, so Only needing to compare the adjacent area in the measurement control message of the measurement report and current service cell that switch abnormal point can Obtain whether be miss-configured neighboring cells, steps are as follows for summary:
1: log import system will be measured, background program will measure the DATA REASONING report message in log and sampled point is believed Breath is written in corresponding table;The measurement log includes at least a measurement report;
2: system automatically analyzes in the PCI reported in measurement report A3 event and current service cell measurement reconfiguration message Neighboring cell list PCI situation;
3: Cell level meets switching condition in measurement report, but does not switch to the cell, and cell PCI is not present in RRC reconfigure in neighboring cell list, then may determine that the cell be miss-configured neighboring cells.
Two: all cells measured being analyzed by certain screening conditions and marking mechanism, find out field strength Continue by force and from the closer adjacent area leakage cell of main serving cell:
Analysis method and process:
1: sampled points all under main serving cell are collected.The level intensity of adjacent cell in sampled point is less than setting The cell of value -110dBm (can customize setting) excludes;Adjacent area at this time is equivalent to the second community.
2: on the basis of the first step, all adjacent cell number of sampling points being counted, total number of sample points is less than setting The cell of value 15 (can customize setting) excludes.
3: on the basis of second step, marking sequence being carried out to all adjacent cells, marking principle is based on following principle: pressing Assignment is ranked up according to the signal quality parameter of each adjacent area of correspondence of the preset function relationship to same sampling location.According to adjacent area Ranking marking, the 1st 6 points, the 2nd 5 points, the 3rd 4 points, the 4th 3 points, the 5th 2 points, the 6th 1 point.It adopts the adjacent area is all Sampling point is added to obtain score to the end, and last score score is higher, sorts more forward.
4: on the basis of third step, the distance between adjacent cell and main serving cell are greater than the set value 1000 meters (can Customized setting) cell exclude.
5:: cell and neighboring cell list in measurement reconfiguration message that the 4th step obtains are compared, see whether be to belong to neighbour The cell of area's leakage.
Final system to two kinds of judging result integrated treatments, if detected the cell of leakage from A3 event and Simultaneously occur in A3 event and sampled point judging result, then be judged as must configure must matched adjacent zone;If detected leakage The cell matched only is from sampled point judging result, then is judged as apolegamy adjacent area.Then in conjunction with the configured adjacent area of existing net cell The ranking of number and cell in sampled point result is to decide whether to belong to the adjacent area that add.
In summary, a kind of method described in this example, firstly, proposing side for searching adjacent area leakage based on A3 event Method, the switching target small area that measurement report reports are to meet the cell of switching condition (especially repeatedly to report but do not have certainly Switch the cell occupied), if this cell not in neighboring cell list, both can determine whether as the cell of adjacent area leakage, this side Method energy fast accurate finds out the cell of adjacent area leakage, avoids the error of artificial judgment;Secondly, level intensity, number of sampling points with And the distance of distance service cell screens the adjacent cell reported, gives a mark and sorts, and result and serving cell is adjacent Area's list compares, and finds out the cell of adjacent area leakage.This calculating process is completed by software, and artificial point-to-point analysis is avoided to sample Point greatly reduces workload, improves working efficiency.
