Problems solved by technology
[0005] In the prior art method of sorting a priori frequency points only according to RSSI, since there may be a large amount of service data in the transmission bandwidth of the LTE system, even if there is no LTE system cell at a certain a priori frequency point, it may be due to the presence of The service data causes the RSSI of the prior frequency point to be very large, and the false frequency point with service data may be ranked before the real frequency point of the LTE system cell, thus making the sorting result inaccurate

The embodiment of the invention discloses a method and a device for ranking prior frequency points, which relate to the technical field of communication and aim at improving the prior frequency point ranking result accuracy in a terminal. The method comprises steps: the terminal acquires a target parameter of each prior frequency point in N prior frequency points maintained by the terminal; according to the N target parameters of the N prior frequency points, the terminal determines a first prior frequency point group in the N prior frequency points; according to the target parameters of the prior frequency points in the first prior frequency point group, the terminal ranks the prior frequency points in the first prior frequency point group, a first ranking result is obtained, and prior frequency points in a second prior frequency point group are ranked according to target parameters of the prior frequency points in the second prior frequency point group, and a second ranking result is obtained; and the terminal combines the first ranking result and the second ranking result to obtain a comprehensive ranking result, and in the comprehensive ranking result, the second ranking result is after the first ranking result.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for sorting prior frequency points. Background technique [0002] At present, in the process of cell search, the terminal needs to detect whether there is a Long Term Evolution (LTE) system signal in the configured frequency band if the frequency band configuration is known. If there is, it needs to be further confirmed. which frequency points, so as to try to camp on cells in the LTE system at these frequency points. [0003] In order to speed up the cell search speed of the terminal, some frequency points are maintained in the terminal as a priori information for priority search, and these frequency points are called a priori frequency points. The prior frequency points include but are not limited to the frequency points that the terminal has successfully camped on before, the frequency points on which the terminal has successfully debroadcas...
