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
The present invention relates to PPP dial technology field, particularly relate to the method and system that automatic detection USB modem network schemer is realized many card dialing.
Background technology
Through country's vigorously supporting in recent years, the 3G network coverage rate of China is more and more wider, in big and medium-sized cities and the surrounding area all have cloth to build, its theoretical bandwidth is more than 2Mbps.In field of video transmission; To video delivery quality and stable, in view of 3G network is merely able to accomplish the responsibility of " transmitting as far as possible ", in case the user of 3G access is many than higher requirement; Data quantity transmitted is big; Then single user's available bandwidth descends greatly, and single user has at any time the possibility of broken string, has a strong impact on the quality of video transmission.
Three kinds of existing 3G technology, the bandwidth of TD-SCDMA is less, seldom adopts the big data on flows of this technical transmission, generally adopts WCDMA and CDMA-2000 as data transfer means.If adopt WCDMA and CDMA-2000 to transmit same data flow simultaneously, will increase transmission bandwidth and stability., often need the modem of two kinds of standards be had Internet access by dialing for this reason, and need these processes of having Internet access by dialing of cover Automatic Program management at same system.
The present invention is in order to alleviate the problems referred to above, and adopting automatically, detection USB modem device network pattern realizes that many cards dial up on the telephone, and solve the automatic management that modem networks effectively.
Summary of the invention
