Patent number: 12267774Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products for a wireless transmit/receive unit (WTRU) to determine slice availability in tracking areas (TAs) of a registration area (RA). In a representative example, the WTRU may use determined slice availability to detect changes in slice availability among different TAs. For example, the WTRU may move from a first TA of a RA where access to a first slice is unavailable to a second TA of the RA where access to the first slice is available. The WTRU may receive information during a registration procedure in the first TA that indicates the first slice is available in less than all TAs of the RA. Upon moving to the second TA, the WTRU may (e.g., again) perform a registration procedure in the second TA of the RA in order to access the first slice in the second TA.Type: GrantFiled: July 25, 2024Date of Patent: April 1, 2025Assignee: InterDigital Patent Holdings, Inc.Inventors: Michael Starsinic, Samir Ferdi, Saad Ahmad, Ulises Olvera-Hernandez, Anuj Sethi
