Abstract

PURPOSE: A method for accessing a radio modem for Internet terminals is provided to set up a radio line using a radio data modem in order to access the Internet by wireless and to connect the radio line to an Internet application service using an access program. CONSTITUTION: If a user issues an Internet access command through an Internet terminal, an Internet terminal part processes it and transmits the processed command to USB(Universal Serial Bus) access part in the form of a USB packet. The USB access part supplies the transferred packet to a radio transceiver part in the form of a control signal. The radio transceiver part enables its internal circuit and initiates call setup for data communication with a base station. The base station forms a radio communication path to the Internet terminal, connects it to an Internet virtual line, and provides a data communication path from the Internet terminal to the network.

Description

Wireless modem connection method for internet terminal {Wireless modem for internet terminal}

The present invention relates to a wireless modem access method for enabling a wireless terminal to access the Internet by wire.

The present invention relates to the field of protocol processing between a wireless modem device and a terminal for wirelessly connecting an internet terminal to the internet.

Conventionally, a wired modem embedded in a terminal has been used to connect to the Internet or a wireless connection has been made through a mobile phone. However, in the case of a wired modem, the wired modem can be used only at a fixed location provided with a telephone line or a dedicated wired channel. A separate connection device was used to connect a mobile phone and an Internet terminal, or to connect a PC IC type wireless data modem to a laptop computer.

The PCC-A wireless data modem was connected to a notebook computer. If you use a mobile phone, you need a separate device that connects the Internet terminal and the mobile phone, and can be used only when both the power of the Internet terminal and the mobile phone's power (battery) are supplied. There was a limited problem.

The present invention provides a matching program for setting up a wireless line using a wireless data modem directly connected to an Internet terminal so that the Internet can be connected and used wirelessly regardless of a place and environment. Use it to perform the same functions as a regular wired modem. Solve the problem that the internet access time is limited due to the limitation of the power usage time of the mobile phone, such as when using a mobile phone by sharing the power of the internet terminal with the wireless modem device, and use a wireless data modem of the type It solves the problem of unstable communication due to the direct influence of the internal noise of the terminal.

Operation as an example of using the wireless Internet;

When the Internet terminal sends a command for accessing the Internet, it is processed by the (C) Internet terminal of FIG. 4 and transmitted in the form of a UESB packet through the USB connection of FIG. 4, and the USB connection unit is in the form of a control signal. Provide to the Department. The wireless transmission / reception unit which has received the control signal from the USS connection unit switches the internal circuit to the operating state and starts call setup for data communication with the base station. At this time, the power required to operate the USB connection and the wireless transmission and reception unit is supplied by the Internet terminal. The base station establishes a wireless communication path to the Internet terminal and connects it to a virtual line of the Internet, thereby providing a data communication path from the Internet terminal to the network.

When the communication path is established, the Internet terminal transfers data transmitted and received to the application software of FIG. When the Internet terminal transmits a command for terminating the Internet, as in the case of the Internet connection, when the end signal is transmitted to the wireless transmitter / receiver through the USB connection unit, the wireless transmitter / receiver sends the signal back to the base station to terminate the data call. (B) The wireless transmitter and receiver of FIG. 4 is implemented by a mobile communication modulation and demodulation technology so that various mobile communication networks can be easily used according to a country-specific wireless environment.
