  • Patent number: 11706614
    Abstract: The disclosed technology separates session management function signaling from the AMF. In particular, an SMF key is created for each SMF following the AMF generating an SM context request that contains gNB information and UE subscription information. Each PDU session creates a direct connection between the SMF and a local gNB. The gNB communicates with each SMF directly over a new interface (N3-C) for session management that is independent of the N2 interface used by the gNB to communicate with the AMF for mobility management. In this way, each SMF independently handles NAS signaling with the UE, using the SMF key and gNB related session-management signaling over an independent interface with the gNB. This removes the burden of relaying these communications through the AMF, which is then freed up to solely to handle mobility management signaling, resulting in an improved architecture.

  • Publication number: 20230209657
    Abstract: The present technology is directed to establishing a connection between a client device within a 2G or 3G network and 5G core through an interworking function. The present technology can perform establishing a Gn-4G interworking function (IWF) between a client access network and a packet anchor network and performing one or more network functions through the Gn-4G IWF in providing a client of the client access network access to network services through the packet anchor network. The one or more network functions appear as one or more Gateway GPRS Support Node (GGSN) functions from the client access network (e.g., 2G or 3G network). The one or more network functions concurrently appear as one or more S4 Serving GPRS Support Node (SGSN) functions from the packet anchor network (e.g., 4G or 5G network).

  • Publication number: 20230102552
    Abstract: A control plane (CP) function for session management performs a procedure for establishing local traffic offloading for a user equipment (UE) in a mobile network having an Evolved Packet Core (EPC) and Fifth Generation (5G) converged core that supports communications via a Long-Term Evolution (LTE) radio access network (RAN) and a Fifth Generation (5G) RAN. Initially, a connection is established for the UE via the LTE RAN, where the connection includes a first bearer between the LTE RAN and a central serving gateway-user plane (SGW-U) at a central location, and a second bearer between the central SGW-U and a central packet gateway-user plane (PGW-U) at the central location. The CP function inserts a local SGW-U at an edge location and subsequently inserts a local intermediate user plane function (I-UPF) with an uplink classifier (UL-CL) at the edge location for enabling edge offload of traffic from the LTE RAN.

  • Patent number: 11252627
    Abstract: A network node includes control plane functionality for managing a session of a user equipment (UE) which is anchored at a User Plane Function (UPF) anchor for communicating traffic between the UE and a data network. The node operates to obtain, from an Access and Mobility Management Function (AMF), a session context request responsive to a handover indication indicating a handover of the session from a Fifth Generation System (5GS) to an Evolved Packet System (EPS). The node identifies whether an uplink classifier (UL-CL) UPF is in use for local offloading to a local UPF anchor for delivery to a local area data network. Based on the identifying, the node obtains uplink tunnel information of the UL-CL UPF instead of the UPF anchor for establishing at least one bearer for the session and sends to the AMF a session context response including the uplink tunnel information of the UL-CL UPF.

  • Patent number: 11246088
    Abstract: A network slice controller obtains health information of an active network slice provided by a first vendor and health information of a set of backup network slices provided by a second vendor. The network slice controller evaluates, using a set of policies corresponding to management of the active network slice, the health information of the active network slice to determine whether the active network slice has failed. As a result of the failure of the active network slice, the network slice controller identifies one or more backup network slices of the set of backup network slices to serve as new active network slices. The network slice controller activates these one or more backup network slices to serve as the new active network slices for the network.
