Abstract

The embodiments of the present invention discloses a frequency band searching method and a related device, wherein the method comprises the steps of after detecting that a SIM card is inserted, obtaining the identification information of the SIM card; determining a target MBN file corresponding to the identification information from a pre-configured MBN file set; according to the target MBN file,configuring a radio frequency scheme and a static radio frequency NV, and searching the target frequency bands needed by the SIM card according to the target MBN file. According to the embodiments ofthe present invention, the efficiency of a communication terminal of searching the frequency bands is conducive to being improved, and the hauling velocity of the communication terminal is speeded.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a frequency band search method and related equipment. Background technique [0002] At present, the diversity of global 2G, 3G and 4G LTE communication frequency bands poses a challenge to the development of communication terminals. Among them, the global 2G and 3G technologies each use 4 to 5 different frequency bands, and the frequency bands supported by LTE in different countries or regions are also different. For example, there are differences between the common LTE frequency bands in Europe and the common LTE frequency bands in South America. [0003] For a communication terminal, when entering a different country or region, it first needs to search for a frequency band, and then register with the network after searching for an available frequency band. However, due to the diversity of current global communication frequency bands, when the same communication terminal...
