User apparatus 2 in a cellular wireless network 14 comprises a user equipment 4 having a first network interface 6 comprising a radio transceiver 8 for communicating via the cellular wireless network 14. The radio transceiver 8 may be set to a first state or to a second state. The user apparatus 2 has a second network interface 10 to a second network 16. A call to the user apparatus 2 is handled by detecting, via the second network interface 10, a request to receive a communication and dependent on the detection of the request via the second network interface 10, switching the radio transceiver 8 to the second state. The communication is then received at the user equipment 4 via the radio transceiver 8. As a result, the user equipment may receive the communication via the cellular wireless network without the need for the user equipment to be continuously camped on the cellular wireless network, so that the cellular wireless network may reduce provisioning of network resources and so reduce power consumption.
