  • Patent number: 10924907
    Abstract: A communication device is provided comprising a receiver configured to detect whether it can receive emergency notification information of a radio cell and, if it cannot receive the emergency notification information of the radio cell, search for another radio cell based on the possibility to receive emergency notification information of the other radio cell. Further, the communication device comprises a controller configured to, if the receiver has found another radio cell based on the possibility to receive emergency notification information of the other radio cell, initiate a reselection of the other radio cell.
