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, the one-dimensional antenna angle of arrival, the one-dimensional sending and receiving time difference, and the two-dimensional time advance and antenna angle of arrival, to the voice In traffic distribution and positioning analysis, the accuracy of traffic distribution and positioning is greatly improved.
[0052] First of all, it needs to be explained that, in each embodiment of the present invention, the one-dimensional time difference between sending and receiving of UE is defined as: T UE-RX –T UE-TX , here: T UE-RX is the receiving timing of the i-th downlink radio frame of the UE from the serving cell, which is defined as the first probing path in time; T UE-TXis the sending timing of the i-th uplink radio frame of the UE; the one-dimensional sending and receiving time difference indicates the number of samples satisfy...

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 technology, in particular to a long term evolution (Long Term Evolution, LTE) traffic distribution precise positioning method and device. Background technique [0002] In the existing LTE system, for positioning of LTE traffic distribution, measurement report (Measurement Report, MR) analysis is mainly used, including the following two methods: [0003] One is to analyze the traffic distribution of the cell through the TA distribution analyzed by the conventional 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 meth...
