  • Patent number: 8649802
    Abstract: The present invention relates to an apparatus and method for location based call signal conversion in a wireless communication network. The location based call signal conversion apparatus comprises an LBS (Location Based Service) server that provides location information on user terminals, and a call signal conversion server that converts the called signal to anyone called terminal on the called target terminal list that has been set up according to the current location of said called user terminal if a call connection request to a receiving user terminal from a sending user terminal is sensed among said user terminals, and if conditions for call signal conversion are satisfied according to the location and state of said called user terminal.
