Problems solved by technology

However, when there is an invalid frequency band (a frequency band that cannot be used actually) in the operating frequency band, such an approach will cause a large amount of unnecessary power consumption (power consumption)
In addition, when some effective frequency bands (frequency bands that can actually be used) are not included in the operating frequency band, unexpected errors may also occur

Embodiment Construction

[0027] The present invention provides various frequency band selection methods, which are applied to a mobile station to dynamically change the setting of the frequency band selection part in the mobile station (such as the setting of the favorite frequency band) to solve the above problems. The mobile station is located in a mobile communication system, and the mobile communication system includes a plurality of cells. First explain the nouns about frequency bands: preferred bands are all the frequency bands set or selected by the user in the mobile station; supported bands include the mobile stations in which the mobile station can work normally All frequency bands; the operating frequency band (bands of operation) is the overlapping part of the favorite frequency band and the support frequency band. The following further describes how the present invention dynamically changes the setting of the favorite frequency band.

Abstract

A mode selection method is utilized in a mobile station. The mobile station can operate in a plurality of supported modes in a mobile communication system. The mobile communication system comprises a plurality of cells. The method comprises: calculating a suggested value of mode selection to match a current environmental state of the mobile communication system; changing a setting of mode selection according to the suggested value of mode selection; camping on a cell according to the setting of mode selection.

Description

technical field [0001] The present invention relates to a frequency band selection method and related devices, in particular to a frequency band selection method and related devices of a mobile communication system. Background technique [0002] For a multi-band mobile station (such as a multi-band mobile phone) capable of operating in multiple frequency bands, the supported bands include all the frequency bands in which the mobile station can normally operate. For example, the supported frequency bands of a quad-band mobile station may include the frequency band 850, the frequency band 900, the frequency band 1800, and the frequency band 1900. When performing a network search or selecting a cell, the mobile station will search for all RF channels in each frequency band within the bands of operation (subset of supported frequency bands). However, when there is an invalid frequency band (a frequency band that cannot be used actually) in the operating frequency band, such an ...
