  • Publication number: 20230045417
    Abstract: Techniques are disclosed for security management during an onboarding process for user equipment. For example, from a perspective of an onboarding network, a method comprises authenticating, via the onboarding network, user equipment based on an onboarding record previously configured for the user equipment or a set of user equipment and maintained by the onboarding network. Upon successful authentication, a communication session is established from the onboarding network to a provisioning server for remote provisioning of the user equipment. Advantageously, the onboarding process is performed without a default credential server.

  • Publication number: 20230032390
    Abstract: Techniques for improving the resiliency of communication networks by providing radio access network data stored in a radio access network database to one or more associated radio access network nodes are provided. A network entity receives a connection request from a user device including at least a radio access network set identifier or radio access network database identifier. The network entity determines whether the radio access network set identifier received in the connection request corresponds to an associated radio access network set identifier. In an instance in which the radio access network set identifier received in the connection request corresponds to the associated radio access network set identifier, radio access network database data are retrieved from the radio access network database associated with the radio access network set identifier. The radio access network database data include at least user device context data for the associated user device.
