A method for controlling the connection between a telematics terminal and an information center is provided to enable the transmission and reception of data to be executed between a telematics terminal and an information center and to enable the telematics terminal to execute a control command as the information center sends the control command in order to make the telematics terminal compulsorily access the information center. An information center selects either the modem or wireless LAN of a telematics terminal in order to make a stable connection. In the case of selecting the modem, the information center transmits a control command to the telematics terminal through an SMS message. The information center is connected with the telematics terminal through the modem according to the control command contained in the SMS message, and data are transmitted through the connected modem. Afterwards, if data transmission is completed, the information center transmits a termination command through the modem. The telematics terminal, receiving the end command, releases the connection with the information center.
