Charging device

A mobile device has several ways to determine position, some of which rely on interaction with the network. Once mobile device establishes a call, the call may remain on the network access technology and band over which the call was established, even if the call requires services not supported by the network access technology and/or band. So, when a call requires a position determination (e.g. emergency call), the mobile device selects a network access technology and band which will potentially improve the probability and accuracy of position determination, even if interaction with the network is not required because other position determination techniques (e.g. GPS) may be available.
