  • Patent number: 12149936
    Abstract: Systems, methods, and computer-readable media are disclosed for dynamically onboarding a UE between private 5G networks. In one aspect, a private 5G (P5G) federation system can receive a request from a user device for registration with a serving private 5G network, which is part of a P5G federation system. The P5G federation system can further determine that the user device is authenticated with a home private 5G network of the user device, which is also part of the P5G federation system. The P5G federation system can transmit, to the serving private 5G network, a security profile of the user device that is received from the home private 5G network. As follows, the P5G federation system can facilitate onboarding of the user device to the serving private 5G network with the security profile.

  • Patent number: 12149399
    Abstract: A monitoring device for troubleshooting events in a datacenter network identifies a first network event for a time period, and provides an initial display page, one or more additional display pages, selectable display objects, and a representation of the first network event. The device generates a dynamic troubleshooting path for the first network event to track a user navigation between display pages, a manipulation of the one or more selectable display objects, and a last-current display page, and also provides an indication of a second network event associated with higher resolution priority relative to the first network event. Retrieving the dynamic troubleshooting path causes the interface to present the last-current display page, apply the manipulation of the one or more selectable display objects, and load the user navigation between the initial dashboard display page and the one or more additional display pages in a cache.
