A method for communicating on a wireless network includes receiving a mode signal from a network node. The mode signal represents an operational mode of the network node. The operational mode is defined by selecting from among a plurality of services at least one service whose reception over the wireless network is to be suspended or reinstated. Communication between the network node and the wireless network is subsequently conducted by taking into account the received mode signal. The network node may be a wireless communicator such as a cellular telephone or a fixed station device. Alternatively, the network node may be a wireless switch or a cellular base station.
