Abstract
The invention expedites the delivery of a call originating in a circuit-switched network to a mobile terminal camped on a packet-switched network. Information representing the location of the mobile terminal in the packet-switched network is provided to the circuit switched network. A call setup with the mobile terminal is initiated with reference to the previously received location information, frequently more expeditiously and using less resources. Location-based services are also provided by the circuit-switched network with access to such mobile terminal location information.
