1. A radio communication device comprising:
- a measurement circuit configured to perform radio measurements to identify one or more cells supporting circuit-switched communications of a combined circuit-switched packet-switched (CS-PS) network in anticipation of circuit-switched orders; and
a control circuit configured to;
identify a pending circuit-switched order supported by the combined CS-PS network while attached to a current packet-switched network; and
switch from the current packet-switched network to the combined CS-PS network to engage in the pending circuit-switched order using a selected cell of the one or more cells,wherein the control circuit triggers the measurement circuit to perform the radio measurements to identify the one or more cells supporting circuit-switched communications of the combined CS-PS network upon the radio communication device switching to a new serving cell of the current packet-switched network.

Abstract
A radio communication device may include a measurement circuit configured to perform radio measurement to identify one or more cells of a combined CS-PS network in anticipation of circuit-switched orders, and a control circuit configured to identify a pending circuit-switched order supported by the combined CS-PS network while attached to a current network, and switch from the current network to the combined CS-PS network to engage in the pending circuit-switched using a selected cell of the one or more cells.

14. Anon-transitory computer readable medium storing instructions that when executed by a controller of a radio communication device control the radio communication device to perform a method comprising:
-
performing radio measurements to identify one or more cells supporting circuit-switched communications of a combined circuit-switched packet-switched (CS-PS) network in anticipation of circuit-switched orders; identifying a pending circuit-switched order supported by the combined CS-PS network while attached to a current packet-switched network; and switching from the current packet-switched network to the combined CS-PS network to engage in the pending circuit-switched order using a selected cell of the one or more cells, wherein the performing of the radio measurements to identify the one or more cells supporting circuit-switched communications of the combined CS-PS network is triggered upon the radio communication device switching to a new serving cell of the current packet-switched network. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A method for a radio communication device to perform radio communications, the method comprising:
-
performing radio measurements to identify one or more cells supporting circuit-switched communications of a combined circuit-switched packet-switched (CS-PS) network in anticipation of circuit-switched orders; identifying a pending circuit-switched order supported by the combined CS-PS network while attached to a current packet-switched network; and switching from the current packet-switched network to the combined CS-PS network to engage in the pending circuit-switched order using a selected cell of the one or more cells, wherein the performing of the radio measurements to identify the one or more cells supporting circuit-switched communications of the combined CS-PS network is triggered upon the radio communication device switching to a new serving cell of the current packet-switched network. - View Dependent Claims (24, 25)
