Abstract: Methods, systems, and devices for offloading traffic flows without service disruption are disclosed herein. User equipment (UE) is configured to receive an indication that a current packet data network (PDN) connection can be optimized. The current PDN connection is established over a first PDN gateway (PGW). The UE requests connection over a new PDN connection to a same type of service as the current PDN connection without releasing the connection over the first PGW. The UE routes new traffic flows over a second PGW corresponding to the new PDN connection and routes old traffic flows over the first PGW.

Abstract: Technology for a virtualized network function manager (VNFM) in a mixed wireless network operable to facilitate instantiation of a virtualized network function (VNF) instance is disclosed. The VNFM can receive a request to instantiate a new VNF instance from a network manager (NM) via a network function virtualization (NFV) orchestrator (NFVO), the request including VNF instantiation information. The VNFM can send a request to a virtualized infrastructure manager (VIM) for allocating virtual resources for the new VNF instance based on the VNF instantiation information. The VNFM can receive an acknowledgement from the VIM after successful allocation of the virtualized resources for the new VNF instance. The VNFM can instantiate the new VNF instance and send an acknowledgement of the new VNF instance to the NFVO, wherein the new VNF instance is operable to ease congestion at an overloaded non-virtualized network element in the mixed wireless network.

Abstract: An architecture, for a cellular communications system, is described herein in which a “bearer-less” model is used for both the radio interface and the network core. Instead of using an individual Layer 2 bearer for each Quality of Service (QoS) class, in the architecture described herein, a common Layer 2 connection (e.g., a Layer 2 “fat pipe”) may be used to handle traffic flows between a User Equipment (UE) device and an external Packet Data Network (PDN). Additionally, a bearer-less architecture may be used in the radio interface (i.e., between User Equipment (UE) and the eNB).

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: Systems and methods of providing 5G access for a UE are generally described. The UE is simultaneously connected via dual radio operation to a legacy and 5G access system. The UE mobility management states for the access systems are independent of each other. The EPC and 5G CN share an HSS and may share a IP anchor. When handover occurs between access systems, the IP address is retained and the IP anchor used when the UE transmits an Attach Request having a Handover Attach Request Type and otherwise a new IP address is provided and the HSS but not the IP anchor is common between the access systems. The 5G eNB to which the UE is connected is standalone and connected to the 5G CN or dual mode and connected with an EPC via an LTE anchor in addition to the 5G CN.

Abstract: Examples may include techniques for monitoring virtual network functions or network functions virtualization infrastructure. Examples include receiving performance measurement data from virtualized network functions arranged to support a network service or from network functions virtualization infrastructure composed to support the virtualized network functions. In some examples, corrective actions such as virtualized network function lifecycle management operations are initiated based on the received performance measurement data.

Abstract: Some demonstrative embodiments include devices, systems and methods of offloading traffic of a Secondary Cell Group (SCG). For example, some embodiments may include identifying a SCG bearer that is offloadable to the Internet via a Network Address Translation (NAT) gateway, based on offloading information received from a Master Evolved Node B (eNB) (MeNB); and offloading uplink Internet Protocol (IP) packets of the SCG bearer to the Internet via the NAT gateway, if the SCG bearer is indicated to be offloadable.
