    Abstract: A wireless network for mobile communications has a connectionless framework using native internet protocol (IP). In this connectionless framework, packet routing may be based on user endpoint (UE) physical IP address, which is associated with the prefix of an associated access node (e.g. eNB). In addition to using the connectionless-IP framework for the traffic flow carried by one access point (e.g. eNB) at a time, advanced mobile call processing features, such as carrier aggregation and dual connectivity, are enhanced to leverage the packet-oriented connectionless radio access network and wireless core network architecture by using the SDN architecture and a wireless network specific software-defined network controller.

    Abstract: A method includes, at a first network endpoint, determining whether a second network endpoint supports receipt of a stream of packets having a quality of service indicator. The method further includes, at the first network endpoint, in response to determining that the second network endpoint supports receipt of the stream of packets having the quality of service indicator, generating and sending the stream of packets having the quality of service indicator and including forward error correction data to the second network endpoint.

    Abstract: A software defined network controller receives from a radio access network access point an attach request generated by a user equipment that includes a user equipment identification and an IP address for the radio access network access point. The controller assigns a temporary identification to the user equipment and sends a modified attach request including the temporary identification, and application server identification and an application server IP address to the radio access network access point. The controller configures a forwarding table associated with the radio access network access point so that the access point forwarding table matches the user equipment identification, the application server identification and the application server IP address. The controller configures a service edge creation environment function forwarding table so that the forwarding table matches the user equipment identification mapped to the radio access network access point IP address and instructs an action so that packet traffic to and from the user equipment is processed without an explicit connection oriented signaling protocol.
