First Claim
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, andwhen 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.

Abstract
A method for estimating the location of a terminal operating in a communication system having at least two networks having overlapping areas of coverage, each network supporting at least one method for estimating the location of the terminal, and the terminal being in communication with a first one of the networks, the method comprising: assessing which of the networks is likely to form the more accurate estimate of the location of the terminal; and if that is the first one of the networks, estimating the location of the terminal by means of the first one of the networks, and if that is a second one of the networks, handing over the terminal to the second one of the networks and estimating the location of the terminal by means of the second one of the networks.
