Abstract: Presented herein is a method that may include obtaining, by a session management node associated with a data session of a user equipment, an indication that an error has occurred at an endpoint of a first tunnel of the data session for the user equipment, the data session having a plurality of flows associated with the first tunnel and a second tunnel; transmitting, to an access and mobility management function (AMF), a request to modify resources for a first plurality of flows associated with the first tunnel; obtaining, from the AMF, a response including an indication of a new tunnel assigned to the first plurality of flows; and transmitting a request to a user plane function (UPF) including an identifier associated with the new tunnel for the first plurality of flows to facilitate transmitting data associated with the first plurality of flows over the new tunnel.

Abstract: An enhanced, fixed broadband access network-mobile network integration for integrating fixed broadband access networks and mobile networks may include a network node having a Broadband Network Gateway (BNG) User Plane (UP) (BNG-UP) function operative to serve as a Branching Point (BP) User Plane Function (UPF). The network node may include a network interface to interface with a Control Plane (CP) for session management and a network interface to interface with a BNG Control Plane (BNG-CP) function. The network node may be configured to process UP traffic based on one or more sets of rules, to forward first UP traffic towards a first UPF to a Data Network (DN) and to forward second UP traffic towards a second UPF to a Local Area Data Network (LADN). Sessions with the CP for session management and the BNG-CP may be identified as related sessions for appropriate processing of the UP traffic.

Abstract: Techniques are described herein for optimizing Quality of Service (QoS) enforcement for handover between different Radio Access Types (RATs). In one example, during an initial user session establishment procedure involving a first RAT, one or more QoS parameters corresponding to a second RAT are obtained. The one or more QoS parameters corresponding to the second RAT are stored to generate one or more stored QoS parameters corresponding to the second RAT. During a handover procedure from the first RAT to the second RAT, the one or more stored QoS parameters corresponding to the second RAT are allocated.

Abstract: A mechanism is provided to ensure the same user plane anchor point is selected as a User Equipment (UE) moves across multiple access networks. The selected User Plane Function (UPF) identifier information, such as a Fully Qualified Domain Name (FQDN) is passed to the UE anchor points. This will allow the UE anchor points to exchange the already selected user plane information so that the new UE anchor point can choose the same UPF.

Abstract: In one example, a base station entity, for a mobile wireless network, obtains an indication of a first potential Guaranteed Bit Rate (GBR), a first unique identifier associated with the first potential GBR, a first priority level associated with the first potential GBR, a second potential GBR, a second unique identifier associated with the second potential GBR, and a second priority level associated with the second potential GBR. Based on the first priority level being associated with a higher priority than the second priority level, the base station entity determines whether the first potential GBR can be supported. If so, the base station entity provides an indication of the first unique identifier to a core network associated with the mobile wireless network, wherein the indication of the first unique identifier prompts the core network to enforce the first potential GBR.

Abstract: In one embodiment, a method includes receiving one or more 5G software-defined wide area network (SD-WAN) policies, identifying one or more identity-based policies from the one or more 5G SD-WAN policies, communicating the identified one or more identity-based policies to one or more WAN routers, communicating one or more 5G bindings to the one or more WAN routers, and applying the identified one or more identity-based policies to one or more flows between the one or more WAN routers.

Abstract: A challenge value is received at a network connected device from a first server. A secure communication channel is established with the first server based on the challenge value. A request is sent from the network connected device to a second server to authenticate with the second server, wherein sending the request comprises sending a challenge response based on the challenge value to the second server prior to receiving a challenge from the second server. A challenge decision is received from the second server at the network connected device. The network connected device authenticates with the second server in response to the challenge decision.
