1. A method for determining the physical location of a user equipment (UE) capable of wireless communication with two or more network operators, comprising the steps of:
- (a) receiving a first message indicating that a location of the UE should be determined;
(b) receiving from a first network operator a first location estimate of the UE;
(c) receiving from a second network operator a second location estimate of the UE;
(d) calculating an improved location estimate of the UE using the estimated locations received from the first and second network operators.

10. A method for determining the physical location of a user equipment (UE) capable of wireless communication with two or more network operators, comprising the steps of:
-
(a) in response to a predetermined event indicating that a location of the UE should be determined, transmitting from the UE to a node operated by a first network operator a first message to enable the first network operator to estimate the location of the UE; and (b) in response to the predetermined event, transmitting from the UE to a node operated by a second network operator a second message to enable the second network operator to estimate the location of the UE. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. An overlayer, comprising:
-
a transmit and receive circuit operable to; receive a first message indicating that a physical location of a user equipment (UE) capable of wireless communication with two or more network operators should be determined, receive from a first network operator a first location estimate of the UE, and receive from a second network operator a second location estimate of the UE; and a data processing system that is configured to calculate an improved location estimate of the UE using the estimated locations received from the first and second network operators. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)

26. A user equipment (UE), comprising:
-
a transmit and receive circuit; and a data processing system configured such that; in response to a predetermined event indicating that a location of the UE should be determined, the data processing system causes the transmit and receive circuit to transmit from the UE to a node operated by a first network operator a first message to enable the first network operator to estimate the location of the UE, and in response to the predetermined event, the data processing system causes the transmit and receive circuit to transmit from the UE to a node operated by a second network operator a second message to enable the second network operator to estimate the location of the UE. - View Dependent Claims (27, 28, 29, 30, 31)
