Mobile station assisted location based service

A method for assisting a base station in determining a location of a mobile station, the method comprising:

• receiving, in at least one assisting station during a page monitoring interval, a resource allocation signal transmitted to the mobile station from a base station;
• receiving a ranging signal in the at least one assisting station from the mobile station;
• and
• transmitting a report to the base station from the at least one assisting station, the report comprising information for determining the location of the mobile station.

A method for initiating a location-based service, the method comprising:

• transmitting a request signal to a base station to request a location-based service;
• transmitting a pilot signal report to the base station to identify pilot signals monitored;
• receiving a resource allocation signal from the base station with instructions to transmit a ranging signal;
• and
• transmitting the ranging signal.

A base station comprising:

• a controller for determining a location of a mobile station, wherein the controller is configured to:
• transmit a request to the mobile station to identify pilot signals monitored by the mobile station;
• receive a pilot signal report from the mobile station to identify the pilot signals monitored;
• determine that a location of the mobile station cannot be determined according to the identified pilot signals;
• transmit a resource allocation signal to the mobile station;
• receive a report from at least one assisting station, the report comprising information for determining the location of the mobile station;
• and
• determine the location of the mobile station according to the information received in the report from the at least one assisting station.
