Problems solved by technology

[0007] In the VISTA system environment, every time a data card is inserted, there will be a user confirmation prompt during the execution of the automatic operation, which brings bad feelings to the user; when a compatibility problem occurs in the timeout switching method, if the virtual CD process cannot be completed normally , the modem port, diagnostic information port, and AT command port cannot be enumerated; every time a data card is inserted, the software resets, causing slow startup

Embodiment 1

[0027] This embodiment guides the data card to enter different states by judging whether a 3G or 2G data card (hereinafter referred to as the data card) is installed with a USIM / SIM card. see figure 1 A method for starting a data card provided in this embodiment includes:

[0028] Step 101: Power on the data card.

[0029] The data card is powered on, and the modules in the data card are initialized.

[0030] Step 102: The data card judges whether a Universal Subscriber Identity Module (USIM, Universal Subscriber Identity Module) or a Subscriber Identity Model (SIM, Subscriber Identity Model) card is in place, and if yes, execute step 105; otherwise, execute step 103.

[0031] After the data card is connected to the PC terminal and powered on and the initialization is completed, the data card detects whether the USIM / SIM card is in place. Specifically, the data card can detect whether the USIM / SIM card is in place in the following ways:

[0032] (1) Detect whether the USIM...

Embodiment 2

[0050] In this embodiment, a switch is installed on the data card, and the data card is guided to enter different states by judging the state of the switch. see figure 2 , this embodiment provides a method for starting a data card, including:

[0051] Step 201: Power on the data card.

[0052] The data card is powered on, and the modules in the data card are initialized.

[0053] Step 202: The data card judges whether the position of the switch is the position corresponding to the installation state, if yes, execute step 203; otherwise, execute step 205.

[0054] In the specific implementation process, when the switch is in the on state, the position state of the switch can be defined as the installation state; when the switch is in the off state, the position state of the switch can be defined as the working state. As an example description. It should be noted that the reverse definition is also possible, that is, the on state is defined as the working state, and the off...

Embodiment 3

[0066] join image 3 , which provides a schematic structural diagram of a data card for this embodiment. The data card can realize self-starting, including:

[0067] Judging module 301, for judging whether to enter the working state;

[0068] The working status processing module 302 is used to enter the working status when the judging result of the judging module 301 is yes, and enumerates the ports required by the user to perform data services;

[0069] The installation state processing module 303 is used for when the judgment result of the judging module 301 is no, then enumerates as the optical drive device, enters the installation state, and carries out the automatic installation of the driver;

[0070] The flag storage module 304 is used for storing the changed state flag after the driver program is installed; the changed state flag indicates that the driver will enter the working state after power-on again.

[0071] Preferably, the judging module can be a USIM / SIM card...

Abstract

An embodiment of the invention discloses a start method and a device for a data card, which belong to the communication field. The method comprises steps of firstly determining whether the data card engages in work or not according to the instruction of a state marker, if positive, engaging in work so as to enumerate as a port required by users for data services, if negative, enumerating as a CD-ROM to engage in installation so as to perform automatic installation of a driver, then storing the changed state marker after the driver is installed, and finally engaging in the work after the data card is powered again under the instruction of the changed state marker. The invention determines whether the data card is engaged in work or not through the instruction of the state marker, thereby realizing separation between a working state and an installation state, and avoiding time-out mechanism and compatibility problems brought during the process of installation.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for starting a data card. Background technique [0002] 3G and 2G data cards have the function of virtual CD-ROM drive and automatic installation, so they are easy to use in win2000 and XP system environments. However, the VISTA system has a strict security mechanism, and there will be a prompt for user confirmation during the execution of Autorun. Because the data card has virtual CD-ROM port, modem port, diagnostic information port and AT command port, after inserting the data card each time, there will be a confirmation prompt when installing the virtual CD-ROM port, modem port, diagnostic information port and AT command port. There is a lot of inconvenience in operation. [0003] Because the data card has a virtual CD port, a modem port, a diagnostic information port and an AT command port, they cannot be enumerated at the same time when the data card is instal...
