Abstract
A network core with a software defined networking (“SDN”) controller is provided to control routing of traffic within the network and between the network and the traffic destination. The SDN controller is merged with existing 3rd Generation Partnership Project (“3GPP”) network architecture to enable service deliveries via open application programming interfaces (“APIs”) and move the network core towards an all internet protocol (“IP”), cloud based, and software driven telecom network. The SDN controller can work with, or take the place of policy and charging rules function (“PCRF”) network elements, so that policies such as quality of service and traffic management and routing can be synchronized and managed end to end.
Claims20
A method, comprising:
- receiving, by a virtualized policy charging and rules function network element of a wireless network device comprising a processor, data from a first mobile device of a wireless network, resulting in received data;
- in response to the receiving the data, applying, by the wireless network device, a routing policy associated with a routing of the data from the first mobile device to a second mobile device, wherein the routing policy is accessed via a data store of the wireless network device;
- based on subscription data associated with a user identity of the first mobile device and routing policy data associated with the routing policy, routing, by the wireless network device, the received data from the first mobile device to the second mobile device;
- and
- based on the subscription data and the routing policy data, performing, by a software defined networking controller of the wireless network device, a quality of service control associated with the first mobile device.
A system, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- in response to receiving data from a first mobile device of a wireless network and based on a control plane function, applying a routing policy via a virtualized policy charging and rules function network element of a wireless network device, associated with routing the data from the first mobile device to a second mobile device;
- receiving subscription data, associated with a user identity, applicable to the first mobile device;
- in response to the applying the routing policy and the receiving the subscription data, facilitating a routing of the data from the first mobile device to the second mobile device by a software defined networking controller of the wireless network device;
- and
- based on the applying the routing policy and the receiving the subscription data facilitating, by the software defined networking controller of the wireless networking device, a quality of service control associated with the first mobile device.
A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
- in response to a transfer of management of a control plane function for first data from a first mobile device, initiating, by a policy charging and rules function network element of a wireless network device, a first traffic management function to be performed on the first data received from the first mobile device, wherein the policy charging and rules function element is a virtualized policy charging and rules function element;
- and
- based on second data representative of a service profile associated with the first mobile device and third data representing a subscription associated with the first mobile device, facilitating, by a software defined networking controller of the wireless network device, a routing function to route the first data to a second mobile device;
- and
- based on the third data representing the subscription and the second data representative of the service profile associated with the first mobile device, controlling, by the software defined networking controller of the wireless network device, a quality of service associated with the first mobile device.
