MOBILE COMMUNICATION SYSTEM AND METHOD CAPABLE OF EXCHANGING DATA BETWEEN MOBILE COMMUNICATION TERMINALS USING PACKET DATA COMMUNICATION

摘要

A mobile communication system and method for exchanging packet data between a host mobile communication terminal and at least one client mobile communication terminal. The host mobile communication terminal sends an SMS message including a list of data to be provided and an IP address for packet data communication. At least one client mobile communication terminal sends a list of data requested to be sent for downloading and authentication information to the host mobile communication terminal over PPP channels set up for the packet data communication. The host mobile communication terminal then sends the data requested by the client mobile communication terminal thereto over the PPP channels. Therefore, data can be exchanged between the host mobile communication terminal and the client mobile communication terminal, without using a separate physical device or means for data exchange.
