Embodiment Construction

[0027] refer to figure 1 A method for automatically detecting the USB modem network mode to realize multi-card dialing, comprising the following steps:

[0028] S01, collect the USB modem device information file supported by the Linux system, and automatically detect the presence status of the USB modem;

[0029] S02, if the USB modem is in place, then read the corresponding USB modem device information, and match with the USB modem device information file;

[0030] S03, determine the network mode of the USB modem in place and its modem serial port number;

[0031] S04. Using the system function in Linux to connect to the Shell script corresponding to the 3G standard to realize PPP dialing.

[0032] As a further preferred embodiment, the PPP dialing includes dialing in two network modes of EVDO and WCDMA.

[0033] refer to figure 2 , further as a preferred embodiment, the content stored in the USB modem device information file includes the manufacturer number, model, netw...

Abstract

The invention discloses a method and a system for realizing multi-card dialing by automatically detecting a USB (Universal Serial Bus) modem network mode. The method comprises the following steps: acquiring a USB modem device information file supported by a system and automatically detecting the in-place state of the USB modem; if the USB modem is in place, reading corresponding USB modem device information and matching the same with the USB modem device information file; determining an in-place USB modem network mode and the modem serial port number thereof; and connecting a script corresponding to Shell by means of system function in Linux to realize PPP (Point-to-Point) dialing. The system comprises an inquiry detection module, a matching module, an internal processing module and a configuration dialing module; therefore, automatic management of a 3G (3-Generation) network dialing access device is realized.

Description

technical field [0001] The invention relates to the technical field of PPP dialing, in particular to a method and system for automatically detecting a USB modem network mode to realize multi-card dialing. Background technique [0002] After the country's strong support in recent years, my country's 3G network coverage has become wider and wider, and has been deployed in large and medium-sized cities and surrounding areas, and its theoretical bandwidth is above 2Mbps. In the field of video transmission, there are relatively high requirements for video transmission quality and stability. In view of the fact that 3G networks can only fulfill the responsibility of "transmission as much as possible", once there are many users connected to 3G and the amount of transmitted data is large, the available bandwidth for a single user It is greatly reduced, and a single user may be disconnected at any time, which seriously affects the quality of video transmission. [0003] Of the three...
