    Abstract: Device to device (D2D) communication can be performed with packet data convergence protocol (PDCP) based encapsulation without internet protocol (IP) addressing. The non-IP D2D PDCP-encapsulated communication can further include two forms of secure data transfer. A first non-IP D2D PDCP-encapsulated communication can be a negotiated non-IP D2D PDCP-encapsulated communication. A second non-IP D2D PDCP-encapsulated communication can be a non-negotiated non-IP D2D communication. The non-negotiated non-IP D2D PDCP-encapsulated communication can include a common key management server (KMS) version and a distributed KMS version. The encapsulated communication can be used with various protocols, including a PC5 protocol (such as the PC5 Signaling Protocol) and wireless access in vehicular environments (WAVE) protocols.

    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: 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: 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.
