Abstract
A software defined network controller for controlling a radio access network has a leaning capability by which usage characteristics are learned for each service provided by the radio access network. For example, bandwidth data, connection duration data and latency data may be used to learn usage characteristics for each radio access network service. The learned usage characteristics are then used in allocating network resources in response to a service request.
Claims20
A software defined network controller, comprising:
- a database store comprising bandwidth usage data, connection duration usage data and latency usage data, wherein each of the bandwidth usage data, connection duration usage data and latency usage data is collected on a per-flow basis for each of a plurality of radio access network services provided on a radio access network;
