Embodiment Construction

[0022] In order to explain in detail the technical solution of the method for detecting overlapping coverage of UE cells in the present invention, some technical terms in some LTE networks will be explained below.

[0023] MR (Measurement Report, measurement report) data consists of information extracted from periodic measurement reports reported from UE to eNodeB (LTE base station) or event reports that trigger handover. These measurement reports carry information about the uplink and downlink wireless links , including reference signal received power, reference signal received quality, timing advance, eNodeB antenna angle of arrival, eNodeB received interference power, etc.

[0024] MR.LteScTadv (timing advance of the serving cell) reflects the signal propagation time from the UE to the serving cell, and is a main indicator reflecting the distance between the UE and the serving cell. This measurement data represents the original measurement value of the timing advance obtain...

Abstract

The invention provides a UE cell overlapping coverage condition detection method and system. A measurement report of UE and cell sites occupied by the UE is obtained, distance between the UE and the cell sites occupied by the UE is calculated, the longitudes and latitudes of the cell sites occupied by the UE are obtained, according to the longitudes and latitudes of the cell sites occupied by the UE, the measurement report of the UE and the cell sites occupied by the UE and the distance between the UE and the cell sites occupied by the UE, the longitude and latitude of the UE are calculated, then a UE cell overlapping coefficient is calculated, and a UE cell overlapping coverage condition detection result is obtained. In the whole process, according to big data mining of the measurement report of the UE and the cell sites occupied by the UE, and based on the distance between the UE and the cell sites occupied by the UE, and geographical location information of the longitude and latitude of the UE and the longitudes and latitudes of the cell sites occupied by the UE, a UE cell overlap coefficient is calculated, and simple and accurate detection of the UE cell overlapping coverage condition is realized.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and system for detecting overlapping coverage of UE (User Equipment, user equipment) cells. Background technique [0002] The LTE (Long Term Evolution, Long Term Evolution) project is the evolution of 3G, which improves and enhances the 3G air access technology, adopts OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) and MIMO (Multiple-Input Multiple -Output, multiple input multiple output system) as the only standard for its wireless network evolution. Under the 20MHz spectrum bandwidth, it can provide the peak rate of downlink 100Mbit / s and uplink 50Mbit / s. It improves the performance of cell edge users, increases cell capacity and reduces system delay. [0003] The communication network using LTE technology is called LTE network. With the continuous deployment of LTE network and the gradual improvemen...
