Abstract

The present invention relates to a data communication card, program and computer readable recording media. A notebook computer transmits a distribution confirmation request including a content attribute, a data communication card performs a matching test for the attribute and notifies of a matching result. When a reservation receiving application requests to start reservation receiving, the data communication card synchronizes with a channel for broadcast to start transferring received data to the notebook computer, and switches a state display to STAND-BY state 2. The reservation receiving application sends a receiving end request upon detection of end of the content. The data communication card stops receiving the broadcast channel and returns the state display to STAND-BY state 1.

Description

technical field [0001] The present invention relates to a communication card, a program, and a computer-readable recording medium on which the program is recorded, and more particularly, to a communication card, a program, and a computer-readable recording medium for broadcast communication services or multicast services. Background technique [0002] Mobile communication systems are widely used for data communication services including multimedia in addition to voice communication services. A mobile notebook PC or PDA terminal is connected to a user terminal such as a communication card corresponding to a mobile communication system or a mobile phone, and can receive mail or access the Internet. Conventionally, when an application program requested by a user is executed, its data communication channel is generally activated to establish a wireless link between a wireless base station and a terminal, and an independent wireless link is used for each session of each terminal....
