RESPONDING TO A PAGING REQUEST FROM A GSM NETWORK BY SETTING UP THE CALL THROUGH A UMTS NETWORK
First Claim
1. A mobile terminal comprising:
- a GSM transceiver that is configured to communicate via a GSM radio communication interface;
a UMTS transceiver that is configured to communicate via a UMTS radio communication interface; and
a controller that is configured to select and register with a UMTS cell provided by a UMTS radio network controller, to store UMTS cell data defining a snapshot of communication characteristics of the selected UMTS cell, to respond to having registered with the selected UMTS cell by monitoring a GSM control channel via the GSM transceiver for an incoming paging request transmitted by a GSM base station controller, and to respond to receipt of the paging request from the GSM base station controller by using the stored UMTS cell data to assist in setting up a corresponding call via the UMTS transceiver and the selected UMTS cell through the UMTS radio network controller and a UMTS core network.

Abstract
A mobile terminal includes a GSM transceiver, a UMTS transceiver, and a controller. The GSM transceiver communicates via a GSM radio communication interface. The UMTS transceiver communicates via a UMTS radio communication interface. The controller is configured to select and register with a UMTS cell provided by a UMTS radio network controller, to store UMTS cell data defining a snapshot of communication characteristics of the selected UMTS cell, to respond to having registered with the selected UMTS cell by monitoring a GSM control channel via the GSM transceiver for an incoming paging request transmitted by a GSM base station controller, and to respond to receipt of the paging request from the GSM base station controller by using the stored UMTS cell data to assist in setting up a corresponding call via the UMTS transceiver and the selected UMTS cell through the UMTS radio network controller and a UMTS core network.

19. A method comprising:
-
receiving notification at a core network through a UMTS radio network controller from a mobile terminal that indicates that the mobile terminal will monitor a GSM control channel from a GSM base station controller for any paging request; responding to the notification by forwarding a paging request, which is received by the core network and is directed to the mobile terminal, to the GSM base station controller for communication to the mobile terminal; receiving a paging response from the mobile terminal through the UMTS radio network controller; and establishing a call with the mobile terminal, responsive to the paging response, through the core network and the UMTS radio network controller.

20. A core network comprising:
a UMTS mobile switching center that is configured to receive notification from a mobile terminal through a UMTS radio network controller that indicates that the mobile terminal will monitor a GSM control channel from a GSM base station controller for any paging request, and to respond to the notification by forwarding a paging request, which is directed to the mobile terminal, to the GSM base station controller for communication to the mobile terminal, and to respond to receipt of a paging response from the mobile terminal through the UMTS radio network controller by establishing a call with the mobile terminal through the UMTS radio network controller.
