Method for call forwarding a call from a mobile telephone

A method of initializing a call forwarding system wherein a call originally placed to a mobile telephone number of a mobile telephone is forwarded to a landline telephone number of a landline telephone associated in a database with a forwarding location, wherein the call is forwarded when the mobile telephone is approximately at the forwarding location, the call being routed through a telephone network by a service provider, the method comprising:

• (a) receiving from the landline telephone a set-up telephone call directed to a predetermined number while the mobile telephone is at the forwarding location and is powered on;
• (b) upon receiving the set-up telephone call, determining the forwarding location using a mobile location technology to locate the mobile telephone using service provider equipment;
• and
• (c) creating a record in the database, the record containing the determined forwarding location associated with the landline telephone number;
• wherein the mobile location technology is an angle of arrival method having the steps of:
• (i) receiving a signal of the mobile telephone at a first antenna site having a first receiver and a second antenna site having a second receiver, wherein each of the receivers is capable of detecting compass direction;
• (ii) determining a first angle of arrival (AOA) when the signal reaches the first receiver and a second AOA when the signal reaches the second receiver;
• (iii) calculating an angular difference between the first AOA and the second AOA;
• and
• (iv) generating the current mobile telephone location expressed in longitude and latitude by using a geographic location algorithm, said geographic location algorithm being a function of the angular difference and geographic locations of the first and second antenna sites.

• (c) creating a record in the database, the record containing the determined forwarding location associated with the landline telephone number;
• wherein the mobile location technology is a location pattern matching method having the steps of:
• (i) creating a database of standard signal characteristics from a plurality of multipath radio frequency (RF) signals generated from a known mobile telephone at a first antenna site having a first antenna, a second antenna, and a multipath RF receiver, wherein each of the standard signal characteristics are associated with a known geographic location;
• (ii) receiving a signal of the mobile telephone at the first antenna site and generating a current signal characteristic;
• (iii) comparing the current signal characteristic to the database of standard signal characteristics and determining a closest match signal characteristic from the standard signal characteristics;
• and
• (iv) generating the current mobile telephone location expressed in longitude and latitude by using the geographic location associated with the closest match signal characteristic in the database of standard signal characteristics.
