Abstract
Provided are, in the 5GS, a method and a communication mechanism for procedures of initial registration of a UE and a periodic or mobility-based registration for implementing management of information about network slice or non-public network function. Furthermore, provided are a method and a communication mechanism for a deregistration procedure after completion of the registration procedure. Furthermore, provided is a method for managing information about network slice in association with each procedure and state transition. Accordingly, provided is, in the 5GS, a communication mechanism for implementing a function related to management of information about network slice or non-public network function.
Claims3
A User Equipment (UE) comprising:
- a controller;
- and
- a storage unit, wherein
- in a case that the UE deregisters with a current Stand-alone Non-Public Network (SNPN) using explicit signalling or enters a 5GMM-DEREGISTERED state for the SNPN, and
- in a case that the UE is not registered with the SNPN over another access type,
- the controller deletes pending Network Slice Selection Assistance Information (NSSAI) for the SNPN from the storage unit.
A communication control method performed by a User Equipment (UE), the communication control method comprising:
- in a case that the UE deregisters with a current Stand-alone Non-Public Network (SNPN) using explicit signalling or enters a 5GMM-DEREGISTERED state for the SNPN, and
- in a case that the UE is not registered with the SNPN over another access type,
- deleting pending Network Slice Selection Assistance Information (NSSAI) for the SNPN from the UE.
