Methods and apparatus for determining relationships in heterogeneous networks
First Claim
1. A method enabling automatic determination that an area covered by an Access Point (AP) of a Wi-Fi Radio Access Network (RAN) overlaps with a cell of a 3rd Generation Partnership Project (3GPP) RAN, the method comprising, at an entity of the Wi-Fi RAN:
- obtaining a 3GPP identifier related to a user terminal that is attached to the Wi-Fi RAN and an identifier for a Wi-Fi AP to which the user terminal is attached;
generating and sending a Location Service Request including the 3GPP identifier to a Location Services (LCS) Server associated with the 3GPP RAN;
receiving a Location Service Response from the LCS Server that includes information identifying the cell of the 3GPP RAN in which the user terminal is located;
causing storage of an association between the identified Wi-Fi AP and the identified 3GPP cell;
recording an indication of a time at which the association between the identified Wi-Fi AP and the identified 3GPP cell is generated; and
when a further association between the identified Wi-Fi AP and the identified 3GPP cell is not generated within a specified time period, cancelling the association between the identified Wi-Fi AP and the identified 3GPP cell.

Abstract
A method enables automatic determination that an area covered by an Access Point (AP) of a Wi-Fi Radio Access Network (RAN) overlaps with a cell of a 3rd Generation Partnership Project (3GPP) RAN. The method comprises, at an entity of the Wi-Fi RAN, obtaining a 3GPP identifier related to a user terminal that is attached to the Wi-Fi RAN and an identifier for an AP of the Wi-Fi RAN to which the terminal is attached. The method further comprises, at the entity, generating and sending a Location Service Request including the 3GPP identifier to a Location Services (LCS) Server associated with the 3GPP RAN, receiving a Location Service Response from the LCS Server that includes information identifying a cell of the 3GPP RAN in which the user terminal is located, and causing storage of an association between the identified Wi-Fi AP and the identified 3GPP cell.

10. A method of operating a Location Services (LCS) Server associated with a 3rd Generation Partnership Project (3GPP) Radio Access Network (RAN) the method comprising:
-
receiving a Location Service Request from an LCS Client within a Wi-Fi RAN, the Location Service Request including a 3GPP identifier related to a user terminal; determining that the LCS Server should respond to the Location Service Request with location information identifying a cell of the 3GPP RAN in which the user terminal is located; obtaining the location information identifying the cell of the 3GPP RAN; and generating and sending a Location Service Response to the LCS Client within the Wi-Fi RAN, the Location Service Response including the location information identifying the cell of the 3GPP RAN, wherein the sending of the Location Service Response to the LCS Client causes the LCS Client to; store an association between an identified Wi-Fi Access Point (AP) and the identified cell of the 3GPP RAN, record an indication of a time at which the association between the identified Wi-Fi AP and the identified cell of the 3GPP RAN is generated, and when a further association between the identified Wi-Fi AP and the identified cell of the 3GPP RAN is not generated within a specified time period, cancel the association between the identified Wi-Fi AP and the identified cell of the 3GPP RAN. - View Dependent Claims (11, 12)

13. A Wi-Fi Radio Access Network (RAN) configured to enable automatic determination that an area covered by an Access Point (AP) of the Wi-Fi RAN overlaps with a cell of a 3rd Generation Partnership Project (3GPP) RAN, the Wi-Fi RAN comprising an entity, the entity comprising:
-
a receiver configured to receive a 3GPP identifier related to a user terminal that is attached to the Wi-Fi RAN and an identifier for a Wi-Fi AP to which the user terminal is attached; a processor configured to generate a Location Service Request including the 3GPP identifier; a transmitter configured to send the Location Service Request to a Location Services, (LCS) Server associated with the 3GPP RAN; the receiver further configured to receive a Location Service Response from the LCS Server that includes information identifying the cell of the 3GPP RAN in which the user terminal is located; and the processor further configured to; cause storage of an association between the identified Wi-Fi AP and the identified 3GPP cell; record an indication of a time at which the association between the identified Wi-Fi AP and the identified 3GPP cell is generated; and cancel the association between the identified Wi-Fi AP and the identified 3GPP cell when a further association between the identified Wi-Fi AP and the identified 3GPP cell is not generated within a specified time period. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A Location Services (LCS) Server associated with a 3rd Generation Partnership Project (3GPP) Radio Access Network (RAN) and configured to provide location information to a Wi-Fi RAN, the LCS Server comprising:
-
a receiver configured to receive a Location Service Request from an LCS Client within the Wi-Fi RAN, the Location Service Request including a 3GPP identifier related to a user terminal; a processor configured to determine that the LCS Server should respond to the Location Service Request with the location information identifying a cell of the 3GPP RAN in which the user terminal is located, to obtain the location information identifying the cell of the 3GPP RAN in which the user terminal is located, and to generate a Location Service Response including the location information identifying the cell of the 3GPP RAN; a transmitter configured to send the Location Service Response to the LCS Client within the Wi-Fi RAN, wherein the transmitter upon sending the Location Service Response to the LCS Client causes the LCS Client to; store an association between an identified Wi-Fi Access Point (AP) and the identified cell of the 3GPP RAN, record an indication of a time at which the association between the identified Wi-Fi AP and the identified cell of the 3GPP RAN is generated, and cancel the association between the identified Wi-Fi AP and the identified cell of the 3GPP RAN when a further association between the identified Wi-Fi AP and the identified cell of the 3GPP RAN is not generated within a specified time period. - View Dependent Claims (24, 25)
