  • Patent number: 10219198
    Abstract: Aspects of the subject disclosure may include, for example, identifying a machine-type communication message directed to a mobile station and determining a compatibility of the mobile station with a 3GPP IMS architecture. In response to determining that the mobile station is compatible with the 3GPP IMS architecture, a forwarding is facilitated of the machine-type communication message to the mobile station via a network element of an IMS network core. In response to determining that the mobile station is not compatible with the 3GPP IMS architecture a forwarding is facilitated of the machine-type communication message to a machine-type communication, interworking function associated with the mobile station, wherein the machine-type communication, interworking function facilitates a directing of the machine-type communication message to the mobile station via an SGs interface of a mobility management entity of an evolved packet core of a 3GPP long term evolution network. Other embodiments are disclosed.

  • Publication number: 20190059016
    Abstract: Concepts and technologies disclosed herein are directed to an enhanced software-defined networking (“SDN”) controller to support ad-hoc radio access technologies (“RATs”). An SDN controller receives, from an ad-hoc radio access controller serving an ad-hoc radio access network (“RAN”), an attach request sent on behalf of a user equipment (“UE”) operating in communication with an ad-hoc RAT transceiver node. The attach request includes a physical IP address associated with the UE. The physical IP address includes an IP address sub-interface pre-fix broadcast to the UE by the ad-hoc RAT transceiver node combined with a physical address of the UE. In response to the attach request, the SDN controller can complete an attachment procedure for allowing the ad-hoc radio access controller to an SDN network. The SDN controller also can update one or more components operating within the SDN network to reflect how to reach the UE via the physical IP address.

  • Patent number: 10148561
    Abstract: Concepts and technologies disclosed herein are directed to providing enhanced quality of service (“QoS”) in a software-defined network (“SDN”)-based connectionless mobility architecture. According to one aspect of the concepts and technologies disclosed herein, an SDN controller can receive service level requirements and can map the service level requirements to QoS requirements and attributes to be associated with a QoS tag. The SDN controller can configure a service entry point to insert the QoS tag into incoming packets so that one or more other service points can extract the QoS tag. The other service point(s) can determine, based upon the QoS tag, a QoS treatment to apply to the incoming packets. The other service point(s) can apply the QoS treatment to the incoming packets in accordance with the QoS tag.

  • Publication number: 20180295057
    Abstract: An SDN controller configures a network element as a service edge. The SDN controller configures a service flow associated with a service to receive a required service treatment. The SDN controller configures an entry point to add routing tags on a set of packets associated with the service. The set of packets are routed in accordance with the routing tags. The required service treatment is applied at the service edge and the tags are removed from the set of packets, which are then forwarded to the network.

  • Publication number: 20180270721
    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.

  • Publication number: 20170332420
    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.
