<p>A node suitable for use in a warning message delivery chain (1) in a telecommunication cellular network, comprising :a receiver for receiving a warning message (2), a state determiner for determining the state of a downstream node (3, 5, 5', 7, 7',9, 9') among "ON" or "OFF", a sender for sending said warning message (2) at least to any downstream node (3, 5, 5', 7, 7', 9, 9') whose state is "ON", a store for storing said warning message (2), a repeater for sending said stored warning message (12) to any downstream node (3, 5, 5', 7, 7',9, 9') whose state is "OFF" during the sending of said warning message (2) by said sender, after the state of said downstream node (3, 5, 5', 7, 7', 9, 9') returns back to "ON".</p> |
