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: Embodiments of the present disclosure describe techniques and configurations for triggering transmission of data payloads in a wireless communication network. An apparatus may include one or more computer-readable media having instructions and one or more processors coupled with the one or more computer-readable media and configured to execute the instructions to implement an interworking function (IWF) to receive, from a Machine Type Communication (MTC) server, a trigger request to trigger sending of a data payload over a wireless communication network, the data payload being smaller than a preconfigured threshold, and send, in response to the trigger request over a reference point to a module including a Mobility Management Entity (MME) or a Serving GPRS (General Packet Radio Service) Support Node (SGSN), a trigger notification to trigger sending of the data payload over the wireless communication network.

Abstract: Wireless communication devices may directly communicate within groups of wireless communication devices using Layer-2 communications to implement “push-to-talk” type applications. In one implementation, a method may include generating a floor request signaling message to take control of a communication channel for a group. After transmitting data relating to the communications, a floor release signaling message may be generated and transmitted a number of times.

Abstract: Briefly, in accordance with one or more embodiments, virtualized network function resources may be managed in a network. Performance measurements may be received for at least one mobility management entity (MME) in an MME pool, or for other network elements. If at least one of the performance measurements exceeds at least one predetermined threshold, instantiation of a new mobility management entity virtual network function (MME VNF) may be requested, and the MME VNF may be instantiated in response to the request. One or more user equipment (UE) devices managed by the MME pool may be connected to the added MME VNF.

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: The techniques introduced here provide for network assisted device-to-device communication for peer-to-peer applications. The techniques include registering a user's peer-to-peer application identifier with a peer-to-peer application server, registering a peer-to-peer application with a device-to-device server, sending a peer-to-peer service request to the peer-to-peer application server, and receiving network assistance in discovering a peer with the desired P2P content/service and establishing a device-to-device communication arrangement for exchange of peer-to-peer services.
