Problems solved by technology

[0015] In order to overcome the problem that the power-on initialization process is relatively long when the PIN code of the existing data card is deactivated, which affects the user experience, the present invention proposes a data card power-on initialization method. After the ARM system initialization process is completed, the USIM card file initialization process is started. When When the USIM card does not need PIN code verification, the initialization process of the data module is performed concurrently with the USB device enumeration and the initialization process of the client software

Embodiment Construction

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the data card startup initialization method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, and the known implementation methods will not be described in detail to avoid confusion with the content of the present invention. There is unnecessary confusion.

[0025] Figure 4 It is a flow chart of a preferred embodiment of the data card startup initialization method of the present invention. The data card is powered on, and the data card startup initialization process starts. After the ARM system is initialized, the data module can work normally, the data module starts automatically, and the USIM card PIN is started. Code status detection (detection of whether the PIN code is deactivated), initialization of USIM card files, and initialization processes such as network residency / registration.

Abstract

The invention discloses a starting-up initialization method for a data card, which is suitable for the field of digital communication. In the method, after the initialization process of an ARM system is completed, the file initialization process of a USIM card is started; and when the USIM card is not needed to be verified by PIN codes, the initialization process of a data module, USB equipment enumeration and the initialization process of client software are performed simultaneously. In the method, when the PIN codes are activated, the file initialization of the USIM card is completed before the client software is started, so that the data card can enter a wireless service available state quickly after the client software is started so as to achieve the aims of shortening the starting-up initialization time of the data card and enhancing user experience.

Description

technical field [0001] The invention relates to a data card startup initialization method, which is suitable for the field of digital communication. Background technique [0002] A data card refers to an Internet access device that integrates a modem, a network adapter, a radio frequency transceiver, and a memory, and is connected to a computer terminal through a USB interface or other access forms (such as a built-in netbook); it can be connected to a computer terminal through a USB interface. Take the 3G data card as an example. The data card uses the power supply of the computer terminal to complete the baseband and protocol stack functions in wireless communication, and then realizes human-computer interaction with the client software on the computer terminal. After the user connects the data card to the computer terminal (the data card is powered on), the user runs the installed client software on the computer terminal (the data card is powered on). After the data card ...
