1. A method of providing location-based services to a mobile terminal in a wireless network comprising the steps of:
- providing a packet-switched network;
providing a location service node;
receiving a location-based service request from the mobile terminal at the location service node;
transmitting a location query to a node of the packet-switched network in response to the location-based service request;
providing location information from the same node of the packet-switched network to the location service node in response to the location query; and
providing at least one location-based service to the mobile terminal using the location information.

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.

10. A method of providing the current location of a mobile terminal comprising the steps of:
-
providing a location service node;
providing a packet-switched network;
providing a circuit-switched network;
transmitting a location request by the location service node to the circuit-switched network;
in response to the location request, the circuit-switched network transmitting at least one location query to a node of the packet-switched network; and
in response to the at least one location query, the packet-switched network transmitting from the same node of the packet-switched network at least one current location message through the circuit-switched network to the location service node. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
