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.

Claims

1. A location-based call forwarding apparatus of a wireless communication network comprising:

an LBS (Location Based Service) server which collects and provides location information of user terminals; and

a call forwarding server which determines, when a calling terminal request a called terminal for a call establishment, whether to perform call forwarding by comparing a call forwarding region as a reference region for determining call forwarding with location of the called terminal and forwards, when the call forwarding is determined, a call destined to the called terminal to one of candidate terminals in a call forwarding-target terminal list.

2. The location-based call forwarding apparatus of claim 1, wherein the call forwarding region is defined by a predetermined distance from a position.

3. The location-based call forwarding apparatus of claim 2, wherein the call forwarding server determines the call forwarding when the called terminal is within the predetermined distance from the position.

4. The location-based call forwarding apparatus of claim 1, wherein the call forwarding server determines whether to perform the call forwarding according to a state of the called terminal as well as the location of the called terminal.

5. The location-based call forwarding apparatus of claim 4, wherein the state can be any of:

a first state in which the call forwarding is performed forcibly regardless of the state of the called terminal,

a second state in which the call forwarding is performed when the called terminal is not registered with the network, and

a third state in which the call forwarding is performed when the called terminal does not accept the call.

9. The location-based call forwarding method of claim 1, wherein determining comprises judging whether to perform the call forwarding according to a state of the called terminal as well as the location of the called terminal.

10. The location-based call forwarding method of claim 9, wherein the state can be any of:

a first state in which the call forwarding is performed forcibly regardless of the state of the called terminal,

a second state in which the call forwarding is performed when the called terminal is not registered with the network, and

a third state in which the call forwarding is performed when the called terminal does not accept the call.

6. A location-based call forwarding method of a wireless communication network, comprising:

collecting, a calling terminal requests a called terminal a call establishment, location information of the called terminal;

determining whether to perform call forwarding by comparing a call forwarding region as a reference region for determining call forwarding with location of the called terminal; and

forwarding, when the call forwarding is determined, a call destined to the called terminal to one of candidate terminals in a call forwarding-target terminal list.

7. The location-based call forwarding method of claim 6, wherein the call forwarding region is defined by a predetermined distance from a position.

8. The location-based call forwarding method of claim 7, wherein determining comprises deciding the call forwarding when the called terminal is within the predetermined distance from the position.
