Method and system for providing data services to mobile communication terminals and mobile communication terminal therefor
First Claim
1. A method of providing at least one data service to a mobile communication terminal in a precinct wireless network, said method comprising steps of:
- automatically executing an application program corresponding to a predetermined data service function of the mobile communication terminal, when the mobile communication terminal enters the precinct wireless network;
making a connection to a data service server through a data channel of the precinct wireless network to execute the data service;
automatically terminating the application program, when the terminal exits the precinct wireless network;
releasing said data channel;
checking for a termination request input by a user of the mobile communication terminal, to terminate the application program after releasing said data channel;
checking for a data service execution request made by the user, when it is determined that the user has not input the termination request;
making a connection to the data service server through one data channel of the precinct wireless network to execute said data service in response to the data service execution request made by the user; and
performing said data service until said user terminates said data service or until said mobile communication terminal exits the precinct wireless network.

Abstract
A method, a system and a mobile terminal for providing data services, whereby specific data services according to a zone of a precinct wireless network are conveniently provided to mobile terminal subscribers in the precinct wireless network, while preventing the maintenance of an unnecessary connection of the terminal to the precinct wireless network. When a mobile terminal enters the precinct wireless network, at least one application program corresponding to a predetermined data service function of the mobile terminal is automatically executed, and thereafter when the terminal exits the precinct wireless network, the application program is automatically terminated. In addition, the terminal opens a data channel connection with the precinct wireless network only when the data service is currently executed in it.

20. A system for providing at least one data service to a mobile communication terminal in a precinct wireless network utilizing a W-PBX (Wireless Private Branch Exchange) providing a mobile communication service to the mobile communication terminal, the system comprising:
-
the mobile communication terminal automatically executing an application program corresponding to a predetermined data service function, which has been set to be automatically executed upon receipt of a precinct wireless network entrance notification message from the W-PBX (Wireless Private Branch Exchange), upon entering the precinct wireless network, the mobile communication terminal including a microprocessor comprising; a data service control module automatically executing the application program upon receipt of said precinct wireless network entrance notification message and automatically terminating the application program when the mobile communication terminal exits the precinct wireless network; the application program also being executable by a subscriber of the mobile communication terminal; and a network connection module for making a data channel connection to the W-PBX (Wireless Private Branch Exchange), wherein the application program comprises; a data service execution module for executing a predetermined data service and for making a connection to a data service server through the network connection module, and an interworking API (Application Program Interface) for interworking with the data service control module to operate the network connection module and the data service execution module; upon exiting the precinct wireless network, the mobile communication terminal automatically terminating the application program. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A system for providing at least one data service to a mobile communication terminal in a precinct wireless network, the system comprising:
-
the mobile communication terminal transmitting a location registration message, for registering its location, to a W-PBX (Wireless Private Branch Exchange), when it enters the precinct wireless network; the W-PBX (Wireless Private Branch Exchange) transmitting a precinct wireless network entrance notification message for notifying the mobile communication terminal of its entrance into the precinct wireless network, in response to the location registration message and if the mobile communication terminal is registered in the precinct wireless network, said W-PBX (Wireless Private Branch Exchange) providing a mobile communication service to the mobile communication terminal; a W-PBX (Wireless Private Branch Exchange) interworking server, connected to the W-PBX (Wireless Private Branch Exchange) through the LAN (Local Area Network), for requesting the W-PBX (Wireless Private Branch Exchange) to notify another mobile communication terminal, which enters the precinct wireless network and has a data service program executed, of a data service execution request made by the mobile communication terminal to said another mobile communication terminal, in response to the data service execution request from the mobile communication terminal, said W-PBX (Wireless Private Branch Exchange) notifying said another mobile communication terminal of the data service execution request, when a data service execution notification request to said another mobile communication terminal is received from the W-PBX (Wireless Private Branch Exchange) interworking server; and the mobile communication terminal automatically executing an data service application program corresponding to a predetermined data service function, which has been set to be automatically executed upon receipt of the precinct wireless network entrance notification message from the W-PBX (Wireless Private Branch Exchange), and upon exiting the precinct wireless network, the mobile communication terminal automatically terminating the data service application program. - View Dependent Claims (32, 33, 34, 35, 36, 37)
