Abstract
A method is described performed by a wireless communication network for recovering a public warning system when a radio network node comprising radio circuitry for communication with served user equipments, UEs, has been newly added or restarted in the network. The method comprises sending, by the radio network node to a core network node, information indicating that the radio network node has been restarted or added to the network, the information including one or more tracking area identifiers, TAI, identifying one or more tracking areas that the radio network node supports and/or a radio network node identifier, ID, identifying the radio network node in the communication network, and, in case the radio network node ID is sent but not the one or more TAIs, acquiring, by the core network node the one or more TAIs based on the received radio network node ID.
