Embodiment Construction

[0020] In order to make the technical solution of the present invention clearer and clearer, the solution of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0021] figure 1 It is a flowchart of the frequency band scanning of the mobile terminal in the present invention. Such as figure 1 shown, including the steps described below:

[0022] Step 101: In this frequency scan, the mobile terminal performs RSSI measurement on each historical effective frequency point whose RSSI measurement value is greater than the preset threshold value in the pre-saved received signal before this frequency sweep, and obtains the RSSI value of each historical effective frequency point. RSSI measurements.

[0023] In a specific embodiment of the invention, the mobile terminal needs to pre-save each historical effective frequency point whose received signal indicates that the RSSI measurement value is greater than the pres...

Abstract

The invention discloses a frequency range scanning method and device of a mobile terminal. The method includes the following steps: firstly, in the process of frequency scanning, the mobile terminal conducts receive signal strength indication (RSSI) measurement to preserved each recorded effective frequency point and an RSSI measured value of the recorded effective frequency point is larger than a threshold value before the frequency scanning, obtaining the RSSI measured value of each recorded effective frequency point, secondly, when the RRSI measured value is smaller or equal to the preset value of each recorded effective frequency point the mobile terminal searching the present effective frequency points and the RSSI measured value is larger than the threshold value within the frequency range supported by the mobile terminal according to researching strategy of preset frequency points at present. According to the method and the device, boot time of the mobile terminal can be effectively reduced.

Description

technical field [0001] The present application relates to mobile communication technology, in particular to a frequency band scanning device for a mobile terminal. Background technique [0002] At present, with the rapid development of communication technology, the performance of various mobile terminals used by people has been continuously improved, and more and more modes and frequency bands are supported. Therefore, when the mobile terminal starts to start, the mobile terminal needs to scan various channels to determine corresponding frequency points. Since there are many frequency bands available for the mobile terminal, the mobile terminal needs to scan all available frequency bands, so the startup speed of the mobile terminal will be prolonged, especially when the mobile terminal enters a roaming area, etc. The operation will take a long time, thus making the booting speed of the mobile terminal slower. For example, when a mobile terminal starts to start in a communi...
