  • Patent number: 11323174
    Abstract: Disclosed are techniques for paging a user terminal (UT) in a non-terrestrial network (NTN), which may define a plurality of NTN tracking areas (TA). Each NTN TA, served by one or more satellite beams, may move or may be a geographic region.

The NTN may estimate UT's current location based on the last reported location and other factors including mobility of the UT. The NTN may determine a UT TA as the NTN TA that corresponds to the current location, and may page the UT through one or more satellite beams corresponding to the UT TA.
