Abstract
According to some embodiments, a method performed by a wireless device operating in a non-terrestrial network (NTN) comprises receiving a first tracking area identity (TAI) from a first cell. The first cell is an earth moving cell and the first TAI is associated with a first fixed tracking area. The method further comprises receiving a second TAI. The second TAI is associated with a second fixed tracking area. The method further comprises determining whether the wireless device should notify a network node of a tracking area update based at least in part on information related to the second TAI, and upon determining the wireless device should notify the network node of the tracking area update, transmitting a tracking area update.
