Abstract: In one example, the present disclosure describes a device, computer-readable medium, and method for dynamically modifying parameters for the delivery of data services over a network. For instance, in one example, a plurality of network slices is provided in a communications network. Each network slice of the plurality of network slices is configured to carry data over the communications network subject to a different combination of network service metrics. When a triggering event is detected in data carried over the communications network using a default slice of the plurality of network slices, the data is dynamically reassigned from the default network slice to a new network slice of the plurality of network slices in response to the detecting.

Abstract: Aspects of the subject disclosure may include, for example, a method including receiving, from a first management gateway of a network, first information associated with first network traffic that is received by the first management gateway from a first access network, determining, from the first information, a first service requested by a first communication device associated with the first network traffic received at the first management gateway, determining a first plurality of service functions required to facilitate the first service for the first communication device, selecting a first core gateway of a plurality of core gateways according to the first plurality of service functions, and transmitting, to the first management gateway, second information identifying the first core gateway, wherein the first management gateway routes the first network traffic to the first core gateway based on the second information. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, detecting network traffic of a traffic flow at a traffic controller of a first portion of a software-defined network, wherein the detected network traffic is based on a service of a number of services. 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. Other embodiments are disclosed.

Abstract: Automatic neighbor relationships (ANR) can be implemented within a radio access network intelligent controller (RIC), which receives load information from network nodes and user equipment measurements from user equipment. The RIC can create and maintain real-time load information and leverage slicing knowledge of neighbor cells during mobility to direct the user equipment to various network slices. Thus, an enhanced radio access network (RAN) neighbor relationship that utilizes slicing information can provide slice level RAN neighbor visibility on top of physical ANR relationships to enable enhancements for mobility management optimization.

Abstract: A method and apparatus for session management in a wireless network are disclosed. For example, a user endpoint (UE) device, sends a request for a session internet protocol (IP) address assignment using an interface IP address, configures the UE device with the session IP address, provides to a controller an association of the interface and session IP addresses, and receives packets addressed to the session IP address via an access network entity associated with the interface IP address. In one example, a controller receives an association of an interface IP address with a session IP address from an attached UE device, provides to a network node an update on a route to reach the session IP address through the interface IP address, identifies an active interface IP address to receive packets, and configures an open flow switch or router for routing the packets towards the active interface IP address.
