Abstract

The embodiment of the invention discloses a method and device for sequencing frequency points of an LTE (Long Term Evolution) system, relating to the field of communication and being capable of realizing the rapid sequencing of the frequency points of the LET system and increasing sequencing accuracy. The method disclosed by the invention comprises the steps of: acquiring filter data of preset frequency bands; determining bandwidth enabling signs of the frequency bands corresponding to the filter data, and merging the frequency bands corresponding to the filter data according to the bandwidth enabling signs to obtain a merged frequency band, wherein the bandwidth enabling signs are true or false; acquiring signal power at each frequency grid inside the frequency bands corresponding to the filter data; calculating a power window specific value at each frequency point inside the merged bandwidth according to the merged frequency band and the signal power at the frequency grids; and sequencing the frequency points according to the magnitudes of the power window specific values correspondingly. The embodiment of the invention is mainly applied in a process for sequencing the frequency points of the LTE system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for sorting frequency points of an LTE system. Background technique [0002] After the terminal starts up for the first time or loses the network signal, it needs to try to search for a suitable cell to reside in. To search for a suitable cell, you must first know the center frequency points of all existing cells, and then select the cell corresponding to the center frequency point with stronger power as The cell that is suitable for the terminal, and the cell corresponding to the center frequency point with stronger power is selected through the frequency point sorting operation. [0003] For the 3G (3rd-generation, third-generation mobile communication technology) mobile communication system, its bandwidth is fixed, and it is easy to search and sort the center frequency points using the traditional center frequency point search method, for example, accordin...
