Embodiment Construction

[0022] refer to figure 1 , the method for automatically determining the call connection configuration in the 3G data card usage system of the present invention comprises the following steps:

[0023] a. If figure 1 In step 01, the 3G data card use system sends an AT command to the serial port of the 3G data card for control, such as AT+CMGS command, to obtain the MCC / MNC (mobile country code / mobile country code / mobile number) of the 3G network to which the SIM card belongs network code) code. The system for using the 3G data card includes a parameter setting module, a PPP dialing module and a configuration file. Wherein, the parameter setting module is used to determine the parameters of the 3G data card network connection, which includes the parameters of each step of automatically determining the call connection configuration described in claim 1, for use by other modules of the 3G data card use system. The PPP dialing module is a known serial port PPP dialing module, and...

Abstract

Disclosed is a method for automatically determining call connection configuration in a third generation (3G) data card using system. The method comprises the steps of sending attention (AT) commands to a serial port of a 3G data card and acquiring a mobile country code (MCC) / a mobile network code (MNC); using the acquired MCC / MNC to query configuration files and obtaining all consilient records; displaying the records to users to select one record if a plurality of records are obtained; outputting obtained record contents to a peer-to-peer protocol (PPP) dial module so that the PPP dial module starts to dial; and acquiring a result of networking success or networking failureby PPP dial module. According to the method, configuration of connection information can be automatically completed to the maximum extent, so that users can complete PPP dial quickly, and quick network access is achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of wireless communication, in particular to a method for automatically determining call connection configuration in a 3G data card usage system. 【Background technique】 [0002] A 3G data card is a device that is applied to a computer and uses the third-generation mobile communication technology to access the Internet. According to the technical standard of 3G network, 3G data card is divided into three categories: WCDMA data card, TD data card and CDMA network card. Like a mobile phone, a 3G data card also requires a SIM card. [0003] When the 3G data card is used as a modem, it modulates the PPP format data signal sent by the computer on the radio carrier and sends it to the station of the mobile communication network, otherwise it demodulates the received wireless signal and restores it to PPP packets are sent to the computer. [0004] Most of the existing 3G data cards have a USB interface. In order...
