Abstract

The invention provides a time advance prediction method and device and a communication system, and relates to the technical field of communication, and the method comprises the steps: obtaining a plurality of pieces of measurement report (MR) data sent by at least one terminal in a terminal set to a base station; grouping the multiple pieces of MR data according to the user session ID to obtain multiple groups of MR data; sorting the multiple pieces of MR data in each group of MR data according to the sending time of each piece of MR data; after sorting, for one piece of MR data missing the timing advance in one group of MR data, determining whether another piece of MR data and another piece of MR data exist before and after the piece of MR data respectively, wherein the other piece of MR data and the another piece of MR data do not missing the timing advance; and if the other piece of MR data and the other piece of MR data exist, predicting the missing time advance of one piece of MR data by adopting a linear interpolation method.

Description

Technical field [0001] The present disclosure relates to the field of communication technologies, in particular a time-forward quantity prediction method, apparatus, and communication system. Background technique [0002] In the LTE (Long Term Evolution, the long-term evolution) system, the different terminals adjust the time of the transmitted signal in the TA, TIMING ADVANCE, so that the uplink transmission signal arrives at the base station within the error range of the length of a cyclic prefix, implements Retain orthogonality between the upstream transmission of multiple terminals to ensure uplink synchronization. TA is carried in the user measurement report MR, which can be used for distance estimation between terminals and antennas, and the distance from 1 TA is about 78.12 meters. TA is often used as a fingerprint parameters of network positioning, and is also used in network optimization analysis. [0003] From the MR data statistics from a certain province, 28% of the M...
