Method for loading mobile phone operating system

Abstract

The invention provides a method for loading a mobile phone operating system. The method comprises the following steps: storing a mobile phone operating system in a subscriber identity module (SIM) card, wherein the mobile phone operating system files stored in the SIM card are classified as cacheable files and non-cacheable files; when the mobile phone loads the operating system, in the case of first loading, storing the cacheable files in a non-volatile memory of the mobile phone, loading the cacheable files of the mobile phone operating system from the non-volatile memory, and loading the non-cacheable files of the mobile phone operating system from the SIM card; and in the case of subsequent loading, directly loading the cacheable files of the mobile phone operating system from the non-volatile memory, and loading the non-cacheable files of the mobile phone operating system from the SIM card. Through the invention, the influence of excessively long time of the mobile phone in loading the operating system on the SIM card due to the limitation on USB (universal serial bus) transmission rate can be reduced, and the user experience is improved.
