Abstract: A wireless terminal receives a network identifier in a message received on a broadcast channel. The wireless terminal determines that a mobile network code in the network identifier corresponds to a non-terrestrial network. The wireless terminal updates a tracking area list of the wireless terminal by adding or deleting a tracking area identifier corresponding to the non-terrestrial network to the tracking area list.
