The document discusses the development of 5G identity and access management (IAM) architecture with a user-centric view. Key points include transitioning to a service-based architecture, defining the basic concept of user identity in 5G with relationships between users, identities and attributes, and developing a 5G user-centric authentication layer and use cases. Authorization of network functions and third-party applications is based on OAuth 2.0 and identity management for mission critical services uses OpenID Connect.
