摘要： A method and a smart card for providing location based services are provided. The smart card connectable to a mobile terminal has a card-dedicated GPS module for receiving radio signals from one or more satellites to extract navigation data contained in the radio signals; a card-dedicated communication module for transceiving data related to the location-based services (LBS) in an interworking relationship with the mobile terminal; a card-dedicated storage module for storing map data related to the location based services and indoor map data; a card-dedicated indoor module for providing the LBS using the indoor map data; and a card-dedicated LBS platform for providing the LBS through extracting a current location of the mobile terminal using the navigation data and controlling the card-dedicated indoor module to be switched into an active state if the card-dedicated GPS module fails to receive the radio signals from the satellite.
