Section: 5.32.5.3 Access Availability/Unavailability Report
Content: If required by the network in the Measurement Assistance Information, the UE shall provide access availability/unavailability reports to the network. How the UE detects the unavailability and the availability of an access is based on implementation. The CM state of a UE is not a factor when determining whether the 3GPP access is available. When the UE detects the unavailability/availability of an access, it shall: - build a PMF-Access Report containing the access type and an indication of availability/unavailability of this access; - send the PMF-Access Report to the UPF via the user plane. The UPF shall acknowledge the PMF-Access Report received from the UE.
