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.
