Description

A kind of analysis method based on MR data

Technical field

The present invention relates to a kind of analysis methods based on MR data.

Background technique

Physical layer measurement is a critical function of LTE system.The measurement result that physical layer reports can be used in system Wireless heterogeneous networks sublayer completes cell reselection or the triggering of the times such as gravity treatment and switching, can be used for system operatio dimension Shield, the operating status of observing system.

Physical layer of the measurement report data of LTE mainly from UE and ENodeb, RLC, and in wireless resource management mistake The measurement report of generation is calculated in journey.Raw measurement data reports and submits OMC-R in the form of statistical data by statistics calculating Store or directly OMC-R is reported and submitted to be stored in the form of sample data.

LTE measurement data covers the network coverage situation of cell, quality of service, Uplink/Downlink interference level, cell Or carrier wave emission function etc..The measured value of eating dishes without rice or wine during user's communication can be obtained, is passed through by acquiring the MR of the whole network Acquisition, analysis measurement report data, can easily find the distribution situation of active user, solve to cover loophole in network, use The common network optimization problem such as family call drop saves a large amount of man power and material so as to substitute the work of part drive test.

The main measurement report of MR is divided into MRS, MRO, MRE three parts, is respectively as follows:

1) MRS:MRS is the measurement report for counting class, and system can generally carry out once counting output, file type for 15 minutes It is the monofile of CSV, general all very little.The network evaluation of quality of service and interference can be carried out with MRS measurement report;

2) MRO:MRO is the measurement report of sample class, does not include the sample data of time trigger, and file type is XML lattice Formula, due to carrying the metrical information of a large amount of second grade, data volume is generally all very big.In addition, MRO and system setting report week There are much relations in phase, and the period is shorter, and the file of generation is bigger;

3) MRE:MRE is the measurement report sample data that event triggers in MR measurement report.

According to different granularities, MRO data can export the measurement report of cell-level, sub-frame level and PRB, at present existing net Smallest particles degree is sub-frame level.Since the gauge outfit of each sample in MRO data contains the information of cell, so weight when analysis The content of point concern MRO output.

In MRO file amount to 46 basic informations, the research of weak covering mainly use MR.LteScRSRP, MR.LteScTadv, MR.LteScAOA this three is analyzed, and MR.LteScRSRP is serving cell RSRP; MR.LteScTadv is that serving cell receives and dispatches the time difference, and distance of the UE apart from base station can be calculated according to this;MR.LteScAOA is Serving cell antenna angle of arrival can calculate UE in the orientation of base station, then go out UE according to the calculation of longitude & latitude of TadV, OA, base station Longitude and latitude.

Specifically, MR.LteScAOA: the reference azimuth of reflection UE corresponding service antenna in cell is reflection UE and service The main indicator of base station location relationship.This measurement data indicates the original measurement of received TD-LTE serving cell antenna angle of arrival Value, unit meet angle measurement dimension.The value is relative value, can analyze the difference of antenna and user distribution by the value.

MR.Tadv UE: for adjusting the time of its main plot PUCCH/PUSCH/SRS uplink transmission.Circular Are as follows: in random access procedure, eNodeB receives pilot signal by measurement to determine time advance value, Timing Advance value Range is (0,1,2 ..., 1282) × 16Ts;Under RRC connection status, eNodeB based on measurement corresponding UE uplink come Determine the TA adjusted value of each UE, the range of this adjusted value is (0,1,2 ..., 63) × 16Ts.This is obtained newest Timing Advance is the Timing Advance of last registration and the sum of the adjusted value that this eNodeB measurement obtains.The value passes through receipts The hair time calculates UE at a distance from base station.

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。
