A wireless communication device arranged to operate in a cellular communication system, the wireless communication device comprising a receiver arranged to receive radio signals from a radio access network node of the cellular communication system; a signal detector arranged to detect a first signal and a second signal among the signals received from the access network node of the cellular communication system, wherein the first signal comprises a network synchronisation signal comprising information about synchronisation and an identification of a cell associated with the access network node, and the second signal comprises a notification, wherein the notification includes a wake-up signal indicating that a paging signal should be read from the received signals; and a controller arranged to cause the signal detector to either detect the notification at a first timing when the received identification of the cell is equal to a previous reception of an identification of a cell at a last mutual interaction between the wireless communication device and the cellular communication system, or detect the notification at a second timing when the received identification of the cell differs from the previous reception of the identification of the cell at the last mutual interaction between the wireless communication device and the cellular communication system. a receiver arranged to receive radio signals from a radio access network node of the cellular communication system; a signal detector arranged to detect a first signal and a second signal among the signals received from the access network node of the cellular communication system, wherein the first signal comprises a network synchronisation signal comprising information about synchronisation and an identification of a cell associated with the access network node, and the second signal comprises a notification, wherein the notification includes a wake-up signal indicating that a paging signal should be read from the received signals; and the first signal comprises a network synchronisation signal comprising information about synchronisation and an identification of a cell associated with the access network node, and the second signal comprises a notification, wherein the notification includes a wake-up signal indicating that a paging signal should be read from the received signals; and a controller arranged to cause the signal detector to either detect the notification at a first timing when the received identification of the cell is equal to a previous reception of an identification of a cell at a last mutual interaction between the wireless communication device and the cellular communication system, or detect the notification at a second timing when the received identification of the cell differs from the previous reception of the identification of the cell at the last mutual interaction between the wireless communication device and the cellular communication system. either detect the notification at a first timing when the received identification of the cell is equal to a previous reception of an identification of a cell at a last mutual interaction between the wireless communication device and the cellular communication system, or detect the notification at a second timing when the received identification of the cell differs from the previous reception of the identification of the cell at the last mutual interaction between the wireless communication device and the cellular communication system.
