Description
Technical Field
The invention relates to the field of embedded software development, in particular to a wireless communication terminal and a self-starting method thereof.
Background
The Universal Serial BUS (USB) data card is a portable internet access tool using USB interface along with the extension and maturity of wireless network technology, and simultaneously along with the development of 3G technology, the USB data card provides a more portable, faster and easier-to-use external extension internet access mode cooperating with a Computer (PC).
The USB data card provides a good PC external expansion means for users, realizes high-quality and high-speed network connection, and has the following advantages and characteristics: (1) the USB device has the common characteristics of plug and play and hot plug; (2) the volume is small, the carrying is convenient, and the portable electric heating water heater is suitable for being used when people go out; (3) the USB data card based on the 3G network can also provide high-speed and high-quality network connection for users; (4) besides network connection, functions such as short messages, voice calls, video calls, card readers of T-Flash cards and the like can be realized.
Fig. 1 is a flow of a working mode of a USB data card in the prior art, and as shown in fig. 1, the USB data card is first enumerated as a device of a cd rom (Compact Disc Read-Only Memory) type, which is used for providing a User with a User Interface (UI) software and a data card driver; if the UI software and the data card driver of the device are installed in the PC at this time, the resident detection program in the operating system directly runs the UI software and the data card driver, and issues a switching instruction to switch the USB data card to a normal working mode (the resident program can be directly switched, or the filtration driver of the Mass Storage device is used for switching, and the switching mode is determined according to the switching mode used by the data card), and the USB data card works in cooperation with the UI software; if the UI software and the data card driving program of the equipment are not installed in the PC at the moment, the installation of the UI software and the data card driving program is started to be carried out by running the installation program from the CDROM, the time is consumed for several minutes in the installation process, then the filter driver issues a switching instruction to switch the USB data card to a normal working mode, the UI software automatically runs, and the USB data card cooperates with the UI software to work; therefore, whether the data card can work normally or not has a very large relationship with an operating system in the user PC; firstly, the operating system of the PC must be able to normally recognize the CDROM device (on the PC with some problematic virtual optical drive software, this premise cannot be guaranteed), secondly, UI software and driver must be able to be normally and smoothly installed (installation failure may be caused by limitation of antivirus software or conflict of other software), and then, the USB data card can be normally used in the operating system of the PC; the disadvantages of the USB data card are: (1) in order to concurrently send multiple services, the USB data card needs to simultaneously virtualize and enumerate multiple functional devices, also called interfaces, such as a VOUSB interface for voice call, an AT interface for sending and receiving short messages, and an NIDS interface for implementing microsoft internet access specification, and these devices are all dedicated and need to be installed with a driver provided by a third party for use, so that a user needs to install multiple device drivers for the first time; meanwhile, in order to realize the automation of installing the driver, the driver is integrated in User Interface (UI) software on the PC side, so that the whole UI software needs to be installed in the first use, and relevant information is left in the hard disk and the registry and the like after installation, thereby increasing the complexity of use and system garbage; (2) a certain waiting time is needed for installing a driver for the equipment, and the installation time consumed is different under different operating systems; in some systems with slower driver installation speed, such as a Windows VISTA system, the driver of each device needs about 20-30 seconds of installation time, and if a USB data card product used by a user virtualizes a plurality of devices, the installation time needs several minutes, which seriously affects the user experience; (3) in the Windows operating system, in the installation process, as the driver on the PC side is influenced by factors such as the current system environment, installed software, the driver and the like, occasionally compatibility problems occur, and the external expression form is that yellow sigh errors occur in a Windows equipment manager, so that the equipment cannot be used; although this is a problem of driver installation with small probability, if the USB data card virtualizes a plurality of devices, the probability of such compatibility problem will inevitably increase, thereby affecting the normal use of the user; (4) in the Windows operating system, users are divided into different security levels, various software and drivers can be normally installed without limit only under the level of an administrator, and users without administrator authority are limited by different degrees; due to the limitation, if the USB data card is temporarily inserted into the PC of another person for temporary use, the UI software on the PC side cannot be normally installed because the USB data card is not the authority of an administrator, and the driver cannot be normally installed, so that the normal use of the user is influenced.
