Study on User Identities and Authentication Architecture
The present document studies how to enhance the 5G System to allow for the creation and utilization of user-specific identities in order to provide enhanced user experience, optimized performance, and offer services to non-3GPP devices and human users. For example, network settings can be adapted, and services can be offered to users according to users' needs, which may be different from the subscription identifier that is used by the user to establish the connection.
In this study, the user to be identified could be an individual human user using a UE with a certain subscription or a device behind a gateway UE or 5G-RG.
Use cases are discussed in clause 26a of TS 22.101 [2] and include:
- an individual human user, using a UE with a certain subscription; and
- a device ("thing") behind a gateway UE.
Requirements related to the collection of charging information for users are specified in clause 5.2.17 of TS 22.115 [3].
NOTE: Charging is in the remit of SA WG5.
