Abstract: Embodiments related to gateway arrangements for wireless communication networks are disclosed herein. For example, in some embodiments, a network controller computing system may include serving gateway (SGW) control plane circuitry to virtualize control plane functions of an SGW, packet data network gateway (PGW) control plane circuitry to virtualize control plane functions of a PGW, first communication circuitry to establish a first secure communication link between the SGW control plane circuitry and an SGW user plane computing system that is to perform user plane functions of an SGW, and second communication circuitry to establish a second secure communication link between the PGW control plane circuitry and a PGW user plane computing system that is to perform user plane functions of a PGW. Other embodiments may be disclosed and/or claimed.

Abstract: Router advertisements may be used to configure multi-homed Protocol Data Unit (PDU) sessions. A first router advertisement message from a first PDU session anchor and a second router advertisement message from a second PDU session anchor may be decoded. A user equipment (UE) may identify, based on the first and second router advertisement messages, a first preference value associated with destination routes of the first network and a second preference value associated with destination routes of the second data network. The UE may determine a destination data network for a signal by comparing a destination route of the signal to destination routes associated with whichever data network has a greater preference value. The UE may prepare the signal with a prefix based on the destination data network.
