Abstract

Intelligent traffic routing may be utilized to route packets of information to one or more radio access technologies and/or cells/access points based on network and/or UE conditions. Packet routes dynamically may be adjusted based on the best radio technology, cell layer, service provider specified criteria, or the like. In an example configuration, intelligent traffic routing may be SDN based utilize a simple Internet protocol.

Claims
