  • 4G/5G SESSION CONTINUITY MANAGEMENT OPTIMIZATION
    Publication number: 20260101171
    Abstract: Systems and methods are provided for optimizing session continuity management during 5th Generation (5G) and 4G/Long Term Evolution (LTE) interworking. Conventional 4G/LTE and 5G interworking involves session continuity subscription or retrieval operations to obtain the latest mobility data for a user equipment (UE) attempting to attach to a particular communications network. These operations include exchanging various messages can be avoided by determining the existence of an Authentication, Authorization, Accounting (AAA)/evolved Packet Data Network Gateway (ePDG) registration (among other conditions).
    Type: Application

  • PROTECTED DEVICE REGISTRATION
    Publication number: 20260095742
    Abstract: Systems and methods are provided for protecting the registration of user equipment (UE). A temporary identifier can be assigned to a UE, and authentication and attachment of the UE to a network can be based on that temporary identifier. A protected time period can be associated with the temporary identifier to prevent collisions with another UE that may be associated with the same temporary identifier.
