Abstract:
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; (e) after step (b), determining whether the UE is currently configured to communicate with the second network operator; and (f) after step (e), in the case that the UE is not currently configured to communicate with the second network operator, transmitting to the UE via the first network operator a network transfer signal indicating that the configuration of the UE should be adjusted to enable communication with the second network operator.
