  • Patent number: 11962585
    Abstract: A Third Generation Partnership Project (3GPP) based network, such as an enterprise private 3GPP network, is operative to provide a guest onboarding of a device using a realm-based discovery of an identity provider and a mutual authentication of identity federation peers. A secure connection may be established between the peers so that the device may be authenticated based on credentials associated with a Subscriber Identity Module (SIM) provided by its Mobile Network Operator (MNO). Credentials may be extended to those associated with embedded SIMs (eSIMs), digital certificates from private enterprises, login and passwords, and identities from a wide range of identity providers. After device authentication, the 3GPP-based network is operative to select and enforce access policies according to an identity or other attribute of the device.

  • Publication number: 20240031808
    Abstract: This disclosure describes techniques and mechanisms for performing user defined network (UDN) service authorization based on secondary identity credentials within a wireless network. For instance, the techniques may include receiving, from a user device, a first request to access a wireless network (e.g., such as a WLAN), where the first request may include primary access credentials for accessing the WLAN. Once primary access authentication of the user device is complete, the techniques may include receiving a second request from the user device to access a UDN group within the wireless network. The second request can include secondary credentials for accessing the UDN group. In response to the second request, a secondary EAP dialogue may be established to authenticate the user device using the secondary credentials. Once the secondary credentials are authenticated, the techniques may include granting the user device access to the UDN group.
