Embodiment Construction

[0017] The present invention will be further described below through a preferred embodiment of the present invention in conjunction with the drawings.

[0018] refer to figure 2 , the mobile phone that the present invention relates to, its specific start-up process is as follows:

[0019] After the mobile phone is powered on, first copy the content of the first stage of the Boot loader stored in the ROM of the mobile phone to the on-chip RAM storage space accessible by the CPU, and the program counter jumps to the first stage of the Boot loader to start executing the instructions in it. A small amount of hardware initialization work will be completed in the first stage of Boot loader, and storage space will be prepared for subsequent startup, and the initialization work of the general integrated circuit card will be completed in the later stage of the first stage of Boot loader.

[0020] After the first stage of the Boot loader is over, copy the complete Boot loader in the e...

Abstract

The invention provides a smartphone without a complete boot module; the complete boot process is performed dependent on an external universal integrated circuit card so as to promote the flexibility and the security of the smartphone. The hardware change of a mobile phone is that a mainboard of the mobile phone needs to connect with a contact point on the external universal integrated circuit card, and an inter-chip interface between the mobile phone and the external universal integrated circuit card can provide high-speed data transmission. The boot process is divided into a first stage and a second stage of Boot loader by the mobile phone provided by the invention, the first stage is stored and only stored on an onboard memory in a mobile phone body; and meanwhile, the initializing function of the external universal integrated circuit card is added on the first stage so as to obtain a complete Boot loader and boot control module from the external universal integrated circuit card.

Description

technical field [0001] The invention belongs to the field of wireless communication and mobile computing, and specifically relates to a smart phone. Background technique [0002] The current smart phones are pre-installed with the operating system and some application software. The inventor noticed that the mobile phone hardware and software binding strategy makes the consumer use inflexible. At the same time, some consumers can easily crack the startup process of the mobile phone, and then directly flash the operating system, bypassing the manufacturer's protection measures. [0003] The invention "Universal Integrated Circuit Card with Booting and Guiding Function for Smartphones" (201110038869.1) discloses a universal integrated circuit card with booting and guiding functions for smartphones. Publicly available universal integrated circuit card. [0004] Universal Integrated Circuit Card (UICC), in the existing mobile communication field, mainly uses storage keys to id...
