Abstract: A framework of abstraction of new and existing 5G radios can enhance capabilities of new and existing micro radios and other short range radio technologies to enable intelligent service delivery, dynamic access learning capability, and network slicing over 5G access networks. Enhancing layer communication for both control and user plane can be tunneled through the hosting layer and exploit a common transport provided by the hosting layer. The tunneling through the hosting layer can also enable the enhance capabilities to access the same radio management functions and can be orchestrated by the same core function.

Abstract: An inter-cell interference coordination procedure in heterogeneous networks (HetNets) is enhanced based on utilization of cell profile data associated with neighbor access points to improve HetNet spectrum efficiency, mobility performance, and/or overall network capacity. In one aspect, a macro access point can receive cell profile data associated with neighbor access points and modify a power level of reduced-power almost blank subframes (ABS) transmitted by the macro access point to manage macro cell capacity. Further, the macro access point can configure the ABS pattern and transmit the ABS pattern to the neighbor access points. Based on the ABS pattern, the neighbor access points can schedule transmissions to user equipment that are located at (or close to) their cell-edge to reduce inter-cell interference.

Abstract: Data can be sent simultaneously on the data links between long-term evolution (LTE) and new radio (NR) for dual connectively. However a mobile device can indicate its capabilities to the network. The mobile device capabilities can comprise the number of total multiple in multiple out (MIMO) layers that the mobile device can support. Because different sectors or markets can have different spectrums that can make use of an increased or decreased number of layers, then assessing the MIMO layer capabilities of the mobile device can allow the network to dynamically adjust the LTE side and the NR side capabilities to optimize network utilization.

Abstract: A gateway may establish a session with an endpoint, receive, from a healthcare application of the endpoint, a setup request for establishing a real time communication tunnel with a destination, the setup request including an incoming port number, the destination associated with a medical provider, and establish a transport layer connection between the endpoint and the destination via the session. The establishing the transport layer connection may include translating the incoming port number to an outgoing port number according to a mapping and forwarding the setup request to the destination via the outgoing port number. The real time communication tunnel may be established between the endpoint and the destination via the transport layer connection, and a second real time communication tunnel between the endpoint and a second destination is established via the session. The gateway may forward a set of messages comprising medical data via the real time communication tunnel.

Abstract: A more efficient network can be achieved by allocating system resources. Dynamic adjustment of system information block periodicity can mitigate system alarms, manual intervention, and performance degradation of the network. System information block messages/data can be given a priority so that resource utilization can be optimized to improve overall system performance. Therefore, system outages can be avoided or mitigated by actively monitoring SIB data and proactively adjusting system resources.

A source of the detected network traffic is identified based on the detected traffic, wherein the traffic flow is between a subscriber device and a service platform. The service is identified based on the detected network traffic, and a service requirement is determined based on the identifying of the service. A virtual network function of a plurality of virtual network functions is selected based on the source of the network traffic and the service requirement, and a traffic flow is facilitated between the subscriber device and the service platform by way of the virtual network function.
