Abstract: A wireless terminal determines a tracking area code (TAC) from a geographic position of the wireless terminal. From the TAC, the wireless terminal determines the tracking area identity based on an indication from the network-side regarding whether or not geographic position based tracking area identity determination is to be used or not. In some implementations, the network-side is a satellite cell that is configured to provide wireless connectivity to the wireless terminal.

Abstract: Methods and systems for handling UE associated information in non-terrestrial networks are disclosed. In one embodiment, a method performed by a satellite head station, includes: translating a first uplink (UL) tunnel address associated with a core network to a second UL tunnel address associated with the satellite head station, wherein the first and second UL tunnel addresses are each associated with a packet data unit (PDU) session established between the core network and a user equipment device (UE); transmitting the second UL tunnel address to a first satellite base station; and receiving UL data associated with the PDU session from the first satellite base station, wherein a UL tunnel address destination associated with the received UL data is set as the second UL tunnel address.
