Abstract:
1. A method comprising: receiving a request for a location of a terminal, the request including an accuracy requirement for the location of the terminal; in response to receiving the request, assessing which network of a communication system having at least two networks with overlapping area of coverage will more accurately determine a location of the terminal, wherein each network of the at least two networks supports at least one method of determining the location the terminal, and wherein the terminal is in communication with a first one of the networks; determining whether the first one of the network is capable of determining the location of the terminal to within a preset tolerance, and when the first network is capable of determining the location of the terminal to within the preset tolerance the location of the terminal is determined using of the first one of the networks; and when the first one of the networks is the network that will more accurately determine the location, initiating determining the location of the terminal using the first one of the networks, and when a second one of the networks is the network that will more accurately determine the location, initiating handing over the terminal to the second one of the networks for determining the location of the terminal using the second one of the networks.
