Mobile communication system and method for exchanging data between mobile communication terminals using packet data communication
First Claim
1. A mobile communication system for exchanging packet data between a host mobile communication terminal and at least one client mobile communication terminal, comprising:
- a packet data serving node (PDSN) for allocating first and second Internet protocol (IP) addresses to said host mobile communication terminal and said at least one client mobile communication terminal, respectively, and establishing first and second point-to-point protocol (PPP) channels with said host mobile communication terminal and said at least one client mobile communication terminal, respectively; and
a short message service (SMS) server for providing an SMS service to said host mobile communication terminal and said at least one client mobile communication terminal;
said host mobile communication terminal receives said first IP address allocated from said PDSN, sets up said first PPP channel with said PDSN using the first IP address, sends an SMS message including said first IP address and a list of data to be provided, to said SMS server, and upon receiving a list of data requested to be sent existing in the list of the data to be provided, sends the data of the requested data list to said PDSN through an authentication process; and
said at least one client mobile communication terminal receives said second IP address allocated from said PDSN, sets up said second PPP channel with said PDSN using the second IP address, sends a download request parameter including said requested data list selected from said list of said data to be provided, to said host mobile communication terminal via said PDSN, and receives said data of said requested data list sent from said host mobile communication terminal;
wherein said host mobile communication terminal includes a socket server application program for managing transmission of data that is requested from each of the client mobile communication terminals, said client mobile communication terminal includes a socket client application program for accessing the host mobile communication terminal.

Abstract
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.

7. A method for exchanging packet data between a host mobile communication terminal and at least one client mobile communication terminal using a mobile communication system, said method comprising the steps of:
-
requesting, by the host mobile communication terminal, a first Internet protocol (IP) address from a packet data serving node (PDSN); establishing a first point-to-point protocol (PPP) channel between the host mobile communication terminal and the PDSN using said first IP address; sending an SMS message including said first IP address and a list of data to be provided, to said at least one client mobile communication terminal from the host mobile communication terminal, via a short message service SMS server; requesting, by at least one client mobile communication terminal, a second IP address from said PDSN; establishing a second PPP channel between the at least one client mobile communication terminal and the PDSN using a second IP address from said PDSN; sending a download request parameter including a list of the requested data from the at least one client mobile communication terminal to said host mobile communication terminal, via said PDSN; sending the data of said requested data list from said host mobile communication terminal to said PDSN through an authentication process, upon receiving said download request parameter; and sending the data of said requested data list from said PDSN to said at least one client mobile communication terminal; wherein said host mobile communication terminal includes a socket server application program for managing transmission of data that is requested from each of the client mobile communication terminals, said client mobile communication terminal includes a socket client application program for accessing the host mobile communication terminal. - View Dependent Claims (8, 9, 10, 11, 12)
