Operating system hot-switching method and device and mobile terminal

Abstract

The invention discloses an operating system hot-switching method applied to a mobile terminal on which multiple operating systems run. The multiple operating systems comprise a front-end operating system and at least one back-end operating system, wherein the current front-end operating system serves as a first operating system, and the at least one back-end operating system comprises a second operating system. The method includes the steps of obtaining an operating system switching instruction, wherein the operating system switching instruction comprises identification and switching identification of the second operating system; according to the switching identification, releasing hardware resources occupied by the first operating system and switching the front-end operating system from the first operating system to the second operating system. The operating system hot-switching method ensures exclusive access to the hardware resources and the coordinate use of the hardware resources of the multiple operating systems to a certain extent and accordingly ensures the reliability of the use of the hardware resources after the operating system is switched.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device and mobile terminal for operating system hot switching. Background technique [0002] Currently, mobile terminals are more and more powerful and support more and more functions, which can meet the requirements of running multiple operating systems on a mobile terminal. However, a mobile terminal can only be exclusively used by one operating system at a time. The method is multi-system cold switching, that is, only one operating system can be started at the same time, and if it is necessary to switch to another operating system, the mobile terminal needs to be restarted. If multiple operating systems can be started at the same time, and hot switching between the two operating systems can be performed quickly, the value and user experience of multiple operating systems can be raised to a new level, and more users can be attracted. A mobile terminal has o...

Problems solved by technology

A mobile terminal has only one set of hardware resources, and the hardware resources are hardware resources used in the mobile terminal to interact with the outside; hardware resources used to interact with the outside, such as: display screen, audio and video, Bluetooth, wireless fidelity (wireless fidelity, Wifi), Global Positioning System (Global Positioning System, GPS), Universal Serial Bus (Universal Serial Bus, USB), Secure Digital (Secure Digital, SD) card, etc., currently running multiple operating systems In mobile terminals, multiple operating systems often use the same hardware resource at the same time, resulting in abnormal use of hardware resources, or even damage to hardware resources. In the prior art, it is impossible to achieve mutual interaction between multiple operating systems on mobile terminal hardware resources. Exclusive Access and Coordinated Use
