Abstract
One aspect provides a method of operating a modem at a terminal. The modem is arranged to store one or more message identifier. Each of the one or more message identifier identifies a type of message that the modem is arranged to act upon when received on a broadcast channel from a communications network. The method comprises detecting a country that the terminal is located in. The method further comprises determining if the detected country is a country in which a public warning system is implemented. The method further comprises determining if the one or more message identifier includes only public warning message identifiers. The method further comprises disabling monitoring of the broadcast channel if the detected country is not a country in which a public warning system is implemented and the one or more message identifier includes only public warning message identifiers.
