Background technology
Current Long Term Evolution (LongTermEvolution, LTE) in network application process, expanding further and network structure day by day complicated along with network size, LTE network adjacent section planning has become a ring important in radio network optimization, and the evil idea of adjacent section planning directly influences network performance.
Adjacent area leakage is joined can cause that user equipment (UE) cannot normally switch, and often produce to go offline call drop, and user's sensation influence is very bad, it is clear that good adjacent section planning is to ensure that LTE network performance provides one of basis of communication service of high-quality.
Compared with other communication systems, the handover measurement of LTE has an obvious feature, namely measures in LTE system and is based on frequency rather than based on Neighboring Cell List.
UE measures, according to measuring the indicated frequency of configuration, the community using this frequency, and then UE processes further according to measurement result, obtains handoff candidate list and issues network, network select community to initiate switching.
The purpose of adjacent section planning is in that to ensure that the mobile phone on cell serves border can be switched to the adjacent cell that signal is best in time, to ensure speech quality and the performance of whole net.Any one subscriber equipment in network all can be subject to the interference of other subscriber equipment in Home Network, any one moves platform and all must pull against these interference and could meet certain service quality, if because of the signal weakening away from Serving cell, best server cell can not be switched in time, then base station and mobile platform are required for strengthening the interference that it is produced by transmitting power to overcome other community, to meet quality of service requirement.When power increases to maximum, still cannot meet service quality, call drop just occurs；Meanwhile, in the process increasing transmitting power, whole net interference increases, and network performance declines.Thus, it is ensured that stable network performance, it is necessary to plan adjacent area well.

Detailed description of the invention
Below in conjunction with Figure of description and specific embodiment technical scheme done and further elaborate.
Embodiment of the method one:
The present embodiment provides a kind of miss-configured neighboring cells processing method, and described method includes:
Obtaining step S110: the measurement report formed when residing in main plot from subscriber equipment, obtain the first cell ID of the first community that subscriber equipment can search for；Described first community is the community beyond described main plot；

Specifically how to determine whether the second community detected in the sampled data of sampling location detection is described first adjacent area, several optional mode of step S150 presented below:
Mode one:
Described step S150 comprises the steps that
To described sampling number according to being analyzed, it is determined that the signal quality parameter of described second cell signal detected in sampling location；Signal quality parameter herein includes the level intensity of signal；
Relatively described signal quality parameter and preset signals quality, form the first comparative result；Specifically relatively more described signal quality parameter with as described in the magnitude relationship of preset signals quality, concrete as compare measurement the second cell signal level intensity and predetermined level intensity between size；
According to described first comparative result, it is determined that described adjacent area is described first adjacent area.
In certain embodiments, it is possible to directly when described signal quality parameter is not less than described preset signals quality, it is determined that the second corresponding community be described must matched adjacent zone；But in order to improve degree of accuracy further, described method also includes in the present embodiment: described signal quality parameter is not less than sampling number corresponding to described preset signals quality according to counting；When described counting is more than default value, it is determined that described second community is described first adjacent area；And when described counting is not more than default value, it is determined that described second community is the community beyond described first adjacent area.
Concrete as, current 50 sampling locations to main plot carry out drive test sampling, find the signal quality parameter sampling number in multiple sampling locations of adjacent area A according in level intensity more than predetermined level intensity, as more than-110dbm, it is possible to directly think this adjacent area be described must matched adjacent zone；Can also is that statistics sampling site data, more than the number of predetermined level intensity, when described number is more than described default value, just think that this second community is described first adjacent area further.If described default value is 15, then can be must time level intensity 15 sampling locations when being all higher than predetermined level intensity, side thinks that described second community is described first adjacent area.Above-mentioned predetermined level intensity is one of them of described preset signals quality, and described level intensity is one of them of signal quality parameter.
Described sampling number evidence can be the statistics in multiple repairing weld data.As carried out 10 samplings 50 sampling locations, in order to determine the stability of described second cell signal, can be specifically that the number of times that signal quality parameter is not less than the sampling number evidence that described preset signals value carrys out energy counts, when described number of times is more than preset times, during such as 7 times, it is determined that this second community is described first adjacent area.
Mode two:
Described step S150 comprises the steps that
To described sampling number according to being analyzed, it is determined that the signal quality parameter of the second cell signal detected in sampling location；To each described second community in each sampling location signal quality ginseng, be integrated assignment by preset function；The integration of each described second community point is accumulated, and accumulation results is ranked up；Determine that described second community is the first adjacent area according to described sequence.
Concrete as, there are 50 sampled points current main plot, and a drive test sampling will form 50 sampling number evidences, and the signal quality parameter of each adjacent area is integrated assignment.The concrete signal quality as characterized at the signal quality parameter of sampling location A, community A is more good, then integration is the highest；The signal quality characterized at the signal quality parameter of sampling location B, community A comes second in the signal quality parameter of each the second community, then integration is only second to top.The A integration 50 sampling locations in Zai Jiang community is accumulated, and accumulation results is ranked up, and final foundation ranking results determines whether described second community is described first adjacent area.
If described signal quality parameter is level intensity；Then level intensity value is more big, then integration is more high；The accumulation results of integration more high, then this second community is that the probability of the adjacent area more closely of the adjacent area incidence relation with described main plot is more big.
Now can passing through to sort, forward several second communities of selected and sorted are as described first adjacent area, or select accumulation higher than several second communities presetting score value as described first adjacent area.
Mode three:
Described step S150 comprises the steps that
Measure the distance of described main plot and each described second community；
When described distance is not more than distance threshold, it is determined that described second community is described first adjacent area.
The distance of main plot and the second small-cell can by the distance between the base station of main plot to the base station of the second small-cell；If the distance between two base stations is excessive, it is clear that the probability that subscriber equipment is switched to this second community from main Serving cell is less.When implementing, described distance threshold can be determined according to the radius of society of described main Serving cell and described second community.If concrete in current network, the radius of all communities is 400 meters, then now, described distance threshold is it is believed that 800 meters, if more than 800 meters, the two community has not been all adjacent area in geographic range, it is clear that do not have the situation being directly switch to this second community from main plot.
Method described in the present embodiment, first pass through the UE measurement report reported, easy defines Lou Pei community, again through drive test data, determine which be must matched adjacent zone and apolegamy adjacent area, provide convenience for follow-up Lou Pei community of whether adding in the adjacent area table of base station, have relative to existing method and realize simple and efficient advantage.

Step S210: drive test obtains the sampling number evidence of described main plot；Wherein, described sampling number is according to the signal quality parameter including the second cell signal: described second cell signal is the signal sent by the second community；Described second community is the community beyond described main plot；
Step S220: according to the signal quality parameter of described second cell signal, it is determined that whether described second community is the adjacent area of main plot；Wherein, described adjacent area is the first adjacent area；
Step S230: by the cell ID of described first adjacent area, compare with the cell ID of the adjacent area being pre-configured with, it is determined that whether described first adjacent area includes in the described adjacent area being pre-configured with；
Step S240: when described first adjacent area is not included in the described adjacent area being pre-configured with, it is determined that described first adjacent area is the miss-configured neighboring cells of described main plot.

Several concrete examples are provided below in conjunction with above-mentioned any embodiment:
Example one:
This example analyzes the lookup LTE adjacent area leakage method of completing the square not only labor intensive time for the playback of existing drive test data, but also can not accurately find out community and the possible error in judgement that adjacent area leakage is joined, adopt that to analyze in measurement report persistent signal intensity in the community and sampled point reported relatively strong and apart from the nearer community of main Serving cell, search adjacent area by certain screening conditions and marking sequence and leak the community joined.
This example includes 2 core contents, and a kind of A3 event being based in measurement report searches Lou Pei community, adjacent area；A kind of is by certain screening conditions and marking mechanism, the adjacent cell measured is estimated, and sees if there is and belongs to the community that adjacent area leakage is joined.Described A3 event is the adjacent area service quality event higher than threshold value.
The first step: analyze A3 event in signaling, A3 affair MR (MeasurementReport, MR) report is decoded, obtains the neighboring BS information of terminal to report, automatically contrast with measuring the neighboring BS information issued in control, obtain adjacent area leakage and join information；
Second step: merge the data in MR report and frequency sweep data, carries out time, space and three dimension weightings of signal intensity and assesses reasonable adjacent area, contrast neighbor cell configuration information, position miss-configured neighboring cells the adjacent area collected；
3rd step: output optimizes base station Neighboring Cell List.
The described first step comprises the steps that searches adjacent area Lou Pei community principle and flow process based on the A3 event in measurement report:
The overall switching flow of 1.1LTE:
The lateral subscriber equipment of network sends wireless resource control connection reconfiguration message RRCConnectionReconfiguration, comprise cell-of-origin Neighboring Cell List and handover trigger and the parameter configuration of measurement report requirement, after meeting switch decision condition, by UE to eNodeB reporting measurement reports, decided whether to perform switching by eNodeB, sending switching command by RRCConnectionReconfiguration to UE, UE completes to configure backward eNodeB feedback RRCConnectionReconfigurationComplete message and completes switching.Described eNodeB is the one of base station, is evolved base station.
LTE switching comprises the steps that
Network side issues RRCConnectionReconfiguration, comprises cell-of-origin Neighboring Cell List and handover trigger and the parameter configuration of measurement report requirement.
After satisfied measurement thresholding, by UE to eNodeB reporting measurement reports, comprise the measured value of cell-of-origin, Target cell PCI and measured value.
After meeting switching condition, eNodeB decide whether to perform switching, send switching command by RRCConnectionReconfiguration to UE, in message, comprise switching target small area PCI.
Switched rear UE to eNodeB feed back wireless heterogeneous networks rush configuration complete RRCConnectionReconfigurationComplete message complete switching.
In LTE signaling, base station can control message to mobile phone by sending measuring, and the neighboring BS information of community is carried in the inside.Terminal to report measurement report can report according to A3 event judgment principle, during the community reported is not controlled by measurement, adjacent area affects, so having only to the measurement report of switching abnormity point and the adjacent area controlled in message of measuring of current service cell being carried out, contrast just can draw whether be miss-configured neighboring cells, sum up step as follows:
1: will measure daily record import system, background program is by the DATA REASONING report message measured in daily record and the corresponding table of sampling point information write；Described measurement daily record at least includes a measurement report；
2: system automatically analyzes the PCI reported in measurement report A3 event and Neighboring Cell List PCI situation in reconfiguration message is measured in current service cell；
3: measurement report small area level meets switching condition, but does not switch to this community, and this community PCI is not present in the Neighboring Cell List during RRC reconfigures, then may determine that this community is miss-configured neighboring cells.
Two: by certain screening conditions and marking mechanism, all communities measured are analyzed, find out field intensity persistently strong and from the Lou Pei community, adjacent area close to main Serving cell:
Analysis method and flow process:
1: sampled points all under main Serving cell are collected.The community less than setting value-110dBm (can customize setting) of the level intensity of adjacent cell in sampled point is got rid of；Adjacent area now is equivalent to described second community.
2: on the basis of the first step, all adjacent cell sampled point numbers to be added up, total number of sample points is got rid of less than the community of setting value 15 (can customize setting).
3: on the basis of second step, all adjacent cells are carried out marking sequence, marking principle is based on following principle: namely according to preset function relation, the signal quality parameter of each adjacent area of correspondence of same sampling location is ranked up assignment.Ranking according to adjacent area is given a mark, the 1st 6 points, the 2nd 5 points, the 3rd 4 points, the 4th 3 points, the 5th 2 points, the 6th 1 point.Being added by all for this adjacent area sampled points and obtain last mark, last mark score is more high, sorts more forward.
4: on the basis of the 3rd step, the distance between adjacent cell and main Serving cell is got rid of more than the community of setting value 1000 meters (can customize setting).
5:: the community the 4th step obtained contrasts with measuring Neighboring Cell List in reconfiguration message, sees that whether being belonging to adjacent area leaks the community joined.
Final system, to two kinds of judged result integrated treatments, comes from A3 event if be detected that leak the community joined and occurs in A3 event and sampled point judged result simultaneously, then what be judged as configuring must matched adjacent zone；It only is from sampled point judged result if be detected that leak the community joined, is then judged as apolegamy adjacent area.Then in conjunction with the adjacent area number that existing network community has configured, and the ranking that community is in sampled point result decides whether to belong to the adjacent area added.
Summary, method described in this example, first, propose a kind of method joined based on A3 event lookup adjacent area leakage, the switching target small area that measurement report reports, be certainly consistent with the community (but particularly repeatedly report and do not switch the community taken) of switching condition, if this community is not in the middle of Neighboring Cell List, both having can determine whether to leak, for adjacent area, the community joined, the method energy fast accurate is found out adjacent area and is leaked the community joined, it is to avoid the error of artificial judgment；Secondly, the adjacent cell reported is screened by the distance of level intensity, sampled point number and distance service community, gives a mark and sequence, and result and service cell neighbor list is contrasted, and finds out adjacent area and leaks the community joined.This calculating process is completed by software, it is to avoid artificial point-to-point analysis sampled point, greatly reduces workload, improves work efficiency.
