Description
Technical field
The present invention relates to a kind of analysis method based on MR data.
Background technology
Physical layer measurement is a critical function of LTE system.The measurement result that physical layer reports may be used for wireless heterogeneous networks sublayer in system and completes the triggering of such as cell reselection or the time such as gravity treatment and switching, it is also possible to for system operation maintenance, the running status of viewing system.
The measurement report data of LTE is essentially from the physical layer of UE and ENodeb, RLC, and calculates the measurement report of generation in RRM process.Raw measurement data or report and submit OMC-R to carry out storing or directly report and submit OMC-R to store with sample data form with statistical data form through statistical computation.
LTE measurement data covers the aspects such as the network coverage situation of community, quality of service, Uplink/Downlink interference level, community or carrier wave emission function.Can pass through to gather the MR of the whole network, obtain the measured value of eating dishes without rice or wine in user's communication process, by gathering, analyzing measurement report data, the distribution situation of active user can be found easily, solve network covers the network optimization problem that leak, conversation loss etc. are common, such that it is able to the work of Substitute For Partial drive test, save substantial amounts of man power and material.
The main measurement report of MR is divided into MRS, MRO, MRE tri-part, is respectively as follows:
1) MRS:MRS is the measurement report of statistics class, and system generally can once add up output in 15 minutes, and file type is the monofile of CSV, generally all only small.Use MRS measurement report can carry out the network evaluation of quality of service and interference；
2) MRO:MRO is the measurement report of sample class, does not include the sample data of Time Triggered, and file type is XML format, and owing to carrying the metrical information of substantial amounts of second level, data volume is generally all very big.It addition, MRO and system arrange report cycle and have much relations, the cycle is more short, and the file of generation is more big；
3) MRE:MRE is the measurement report sample data that in MR measurement report, event triggers.
According to different granularities, MRO data can export the measurement report of cell-level, sub-frame level and PRB, and current existing network smallest particles degree is sub-frame level.Owing to the gauge outfit of sample each in MRO data contains the information of community, so paying close attention to the content of MRO output when analyzing.
Amounting to 46 Back ground Informations in MRO file, the research of weak covering mainly uses MR.LteScRSRP, MR.LteScTadv, MR.LteScAOA these three to be analyzed, and MR.LteScRSRP is Serving cell RSRP；MR.LteScTadv is Serving cell transmitting-receiving time difference, can calculate the UE distance apart from base station according to this；MR.LteScAOA be serving cell antenna arrive angle, the UE orientation in base station can be calculated, then according to TadV, OA, base station calculation of longitude & latitude go out the longitude and latitude of UE.
Specifically, MR.LteScAOA: the reference azimuth of reflection UE corresponding service antenna in cell, is the leading indicator of reflection UE and serving BS position relationship.This measurement data represents that the TD-LTE serving cell antenna of reception arrives the original measurement value at angle, and its unit meets angular surveying dimension.This value is relative value, can be analyzed the difference of antenna and user distribution by this value.
MR.TadvUE: for adjusting the time of its main plot up transmission of PUCCH/PUSCH/SRS.Circular is: at random access procedure, eNodeB by measure receive pilot signal determine time advance value, Timing Advance span be (0,1,2 ..., 1282) × 16Ts；Under RRC connection status, eNodeB determines the TA adjusted value of each UE based on the uplink measuring corresponding UE, and the ranging for of this adjusted value (0,1,2 ..., 63) × 16Ts.This up-to-date Timing Advance obtained is the adjusted value sum that the Timing Advance of last registration obtains with this eNodeB measurement.This value calculates the distance of UE and base station by the transmitting-receiving time.
UE sampled point calculation of longitude & latitude formula:
Lon=X+ [r*sin(a]/[111000*cos(Y*pi/180)]；
Lat=Y+ [r*cos(a*pi/180)]/111000。
