Abstract
A network node obtains (302) a message to be transmitted as a public warning system notification to multiple UEs, via one or more SIBs, and obtains (304) area information corresponding to the message. The area information indicates an area for which the message is relevant. The network node determines (306) how many SIBs are needed for transmitting the area information and segments (308) the message into a plurality of segments, based on how many SIBs are needed for transmitting the area information. The network node transmits (310) the message and the area information via SIBs, such that a segment of the message is included in each SIB and such that each portion of the area information included in a SIB is accompanied by a segment of the message. A UE receives the SIBs and assembles the message and area information, displaying the message if it is relevant.
