Abstract
Network selection techniques for use in a mobile device which is configured for voice and packet data communications are described. The mobile device performs a scanning operation to identify one or more communication networks, and consults a network selection list for selecting, in accordance with assigned priorities of the list, one of the identified networks. The mobile device also determines whether a packet data service interconnection to a home network via the selected network is available. If the interconnection to the home network via the selected network is determined to be available, then the mobile device operates with voice and packet data services in the selected network. Otherwise, if the interconnection to the home network via the selected network is determined to be unavailable, then the mobile device repeats the acts of consulting and determining for the next identified network in the list.
