Description

technical field [0001] The present invention relates to the field of LTE (Long Term Evolution, long-term evolution of general mobile communication technology) network technology, in particular to a method for obtaining correlation coefficients of same-frequency cells based on LTE networks and a method for obtaining correlation coefficients of same-frequency cells based on LTE networks device. Background technique [0002] The LTE is a long-term evolution of the UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) technical standard formulated by the 3GPP (The 3rd Generation Partnership Project, Third Generation Partnership Project). The LTE system introduces key technologies such as OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multi-Input&Multi-Output, multiple input multiple output), which significantly increases spectrum efficiency and data transmission rate; supports multiple bandwidth allocations , and supports the...

Problems solved by technology

[0006] (1) Data integrity problem: the calculation of the correlation coefficient (that is, the MR detection ratio of the same frequency cell) is completely derived from the MR data collection, but the lack of MR is common at present, and the correlation between cells is often caused by the lack of MR. lost;

[0007] (2) Road cell correlation problem: The MR reporting interval is usually set to 5.12 seconds, and most mobile terminals on the road are in a high-speed state, especially on expressways

Due to the large time interval of MR sampling and the fast speed of mobile terminals, the correlation coefficient obtained from MR data cannot accurately reflect the correlation of road cells;

[0008] (3) Failure to accurately reflect the relationship between the edge cells: Most of the MR data collection comes from non-roaming users, that is, data collected in the same cell, which fails to accurately reflect the precise relationship between the two cell edges
