Problems solved by technology
[0003] One is to analyze the traffic distribution of the cell through the TA distribution analyzed by the Measurement Result Recording (MRR). This method is simple and suitable for large-scale network element analysis. However, this method cannot accurately locate the location information
[0004] The second is to use the Ericsson tool CTR to correlate and analyze the poor quality of the cell with the distribution of TAs and other indicators, which can more intuitively present the traffic distribution distance of the cell. However, this method can only be used for task formulation and analysis at the cell level, and cannot The range is collected uniformly, so the timeliness is extremely poor and the labor cost is extremely high

Embodiment Construction
[0051] In each embodiment of the present invention, by applying the one-dimensional statistics and two-dimensional statistics of LTE MR data, that is, one-dimensional antenna angle of arrival, one-dimensional transmit and receive time difference, two-dimensional time advance and antenna angle of arrival, to the telephone In the analysis of traffic distribution and positioning, the accuracy of traffic distribution and positioning is greatly improved.
[0052] First of all, it should be noted that, in each embodiment of the present invention, the one-dimensional sending and receiving time difference of the UE is defined as: T UE-RX –T UE-TX , here: T UE-RX is the receiving timing of the ith downlink radio frame of the UE from the serving cell, and is defined as the first sounding path in time; T UE-TXis the sending timing of the ith uplink radio frame of the UE; the one-dimensional sending and receiving time difference represents the number of samples that satisfy the value ra...

The embodiment of the invention provides a precise positioning method of LTE telephone traffic distribution. The method comprises: determining a first interval as well as a first sampling point number of the first interval according to a one-dimensional antenna arrival angle and a one-dimensional transceiving time difference; according to a two-dimensional time advance and an antenna arrival angle, determining a second interval as well as a second sampling point number of the second interval; on the basis of the second interval and the second sampling point number in the second interval, correcting the first sampling point number; and determining an LTE telephone traffic distribution situation based on the first interval and the corrected first sampling point number. In addition, the embodiment of the invention also provides a precise positioning apparatus of LTE telephone traffic distribution.
Description
technical field [0001] The present invention relates to wireless communication technologies, and in particular, to a method and device for precise positioning of traffic distribution in Long Term Evolution (LTE). Background technique [0002] In the existing LTE system, for the positioning of LTE traffic distribution, measurement report (Measurement Report, MR) analysis is mainly used, including the following two methods: [0003] The first is to analyze the traffic distribution of the cell through the TA distribution analyzed by conventional measurement result recording (MRR). This method is simple and easy to implement and suitable for large-scale network element analysis. [0004] Second, the Ericsson tool CTR is used to correlate the poor quality of the cell with the TA distribution and other indicators, and more intuitively present the traffic distribution distance of the cell. However, this method can only be used for cell-level task formulation and analysis, not large...
