  • Publication number: 20220312192
    Abstract: Correlating devices and clients across addresses may be provided. A first address associated with a client device may be received. When the client device is not connected to a network, first location data associated with the first address may be obtained using a passive technique. A second address and second location data associated with the second address may then be obtained using an active technique. It may then be determined that the first location data and the second location data correlate. In response to determining that the first location data and the second location data correlate, it may be determined that the client device has changed from the first address to the second address.

  • Patent number: 11202276
    Abstract: In one example, a control plane entity obtains an indication that a User Equipment (UE) has entered an idle mode. The control plane entity sets a routing locator corresponding to the UE to cause the control plane entity to trigger a paging request toward the UE to prompt the UE to transition from the idle mode when a first network node obtains a downlink packet destined for the UE. The control plane entity obtains a notification that the first network node has obtained the downlink packet and initiates the paging request toward the UE. The control plane entity updates the routing locator corresponding to the UE to cause the first network node to transmit further downlink packets destined for the UE toward a second network node configured to handle traffic on behalf of the UE.

  • Publication number: 20210195406
    Abstract: In one example, a Network Policy Function (NPF) obtains a first identifier for a User Equipment (UE) based on communications between the UE and a first access network of a system, and an Internet Protocol (IP) address used by the UE to communicate over the first access network. The NPF obtains a second identifier for the UE based on communications between the UE and a second access network of the system. The NPF determines that the UE used the IP address to communicate over the first access network of the system based on a correlation between the first identifier for the UE and the second identifier for the UE. The NPF provides the IP address to the UE, and the UE uses the IP address to communicate over the second access network.

  • Publication number: 20210136871
    Abstract: In one illustrative example, an interface between a user plane function (UPF) instance of a mobile network and a tunnel router endpoint of an enterprise software-defined wide area network (SD-WAN) fabric is provided. The UPF instance may be part of a network slice that is (uniquely) associated with an enterprise of the enterprise SD-WAN. A plurality of mappings between policies associated with different QoS flows via the UPF instance and SD-WAN policies associated with different virtual private networks (VPNs) of the SD-WAN fabric may be maintained. Each VPN of the SD-WAN fabric may be associated with a different underlying transport mechanism that satisfies characteristics of a specific SD-WAN policy. Communications for user equipment (UE) in the mobile network may be facilitated across the SD-WAN fabric based on the policy mappings.
