Title:
VIRTUAL TRACKING OR REGISTRATION AREAS FOR NON TERRESTRIAL NETWORKS
Document Type and Number:
WIPO Patent Application WO/2021/066487
Kind Code:
A1
Abstract:
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system or a 6th-Generation (6G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system. A method and apparatus in a wireless communication system is provided. The method and apparatus comprises: identifying a virtual tracking area (VTA) to tracking area (TA) (VTA-TA) mapping information indicating mappings between (i) TA identifiers (TAIs) associated with a non-terrestrial network (NTN) entity and (ii) VTAs associated with geographical areas as a function of time; identifying one or more TAIs at an instant or during a time period based on the VTA-TA mapping information; transmitting a radio resource control (RRC) request message including the one or more TAIs; and receiving an RRC response message corresponding to the RRC request message based on the one or more TAIs. The RRC response message includes a virtual registration area (VRA).
