Embedded 3G network card working method and system

Abstract

The invention provides an embedded type 3G (the third generation telecommunication) networking card working method. The embedded type 3G networking card working method comprises the following steps: detecting a PID / VID in a default list of a 3G networking card and additionally arranging a configuration tree containing a new PID / VID; switching a MODEM module of the 3G networking card into a MODEM state; detecting the PID / VID in the default list of the 3G networking card under the MODEM state and judging whether the PID / VID of the 3G networking card exists in the default list or not; if so, driving 3G dial-up networking according to a script corresponding to the PID / VID of the 3G networking card; otherwise, detecting the PID / VID in the configuration tree under the MODEM state and judging whether the PID / VID of the 3G networking card exists in the configuration tree or not; if so, driving the 3G dial-up networking according to pattern description of the configuration tree and the script corresponding to the PID / VID of the 3G networking card; otherwise, quitting the dial-up networking. Moreover, the additionally-arranged configuration tree containing the new PID / VID is used for detecting, so that a new type is increased through updating the configuration tree of the PID / VID, and furthermore, the embedded type 3G networking card dial-up is realized without updating firmware. Furthermore, the invention provides an embedded type 3G networking card working system.

Description

technical field

[0001] The invention relates to a 3G network card, in particular to an embedded 3G network card working method and system without updating firmware. Background technique

[0002] The 3G network card is a widely used Internet medium for wireless wide-area communication networks. At present, my country has three network standards: China Mobile's td-scdma, China Telecom's CDMA2000 and China Unicom's WCDMA. Therefore, common wireless network cards include CDMA2000 wireless network cards and TD and WCDMA wireless network cards. The common interface is the USB interface, which is used after installing the driver on the PC. At the same time, some routers support this type of device through the USB interface.

[0003] Generally, routers have built-in support for 3G network cards, and the general process is as follows: After the system connects to the hot-swap device, it sends hot-swap information, and then the 3G device daemon analyzes the hot-swap information to r...

[0049] Such as figure 1 As shown, it is a flow chart of the working method of the embedded 3G network card.

[0050] A working method for an embedded 3G network card, comprising the following steps:

[0051] Step S110, detecting the PID / VID in the default list of the 3G network card, and adding a configuration tree containing the new PID / VID. The configuration tree is configuration area data.

[0052] The steps for adding a configuration tree with a new PID / VID include:

[0053] Add new PID / VID and corresponding script in the configuration area of ​​the 3G network card, and use the script corresponding to the new PID / VID to drive 3G dial-up to access the Internet.

[0054] Determine whether the script corresponding to the new PID / VID is used to drive 3G dial-up Internet access successfully.

[0055] If yes, save the newly added PID / VID in the configuration area.

[0056]If not, add a new PID / VID in the configuration area again.
