Patent number: 10219198Abstract: 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.Type: GrantFiled: May 24, 2016Date of Patent: February 26, 2019Assignee: AT&T Intellectual Property I, L.P.Inventors: Rajendra Prasad Kodaypak, Christopher Bryant, Ryan Redfern, Jiansong Wang

Publication number: 20190059016Abstract: 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.Type: ApplicationFiled: October 22, 2018Publication date: February 21, 2019Applicant: AT&T Intellectual Property I, L.P.Inventors: Zhi Cui, Jiansong Wang

Publication number: 20180270721Abstract: 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.Type: ApplicationFiled: March 17, 2017Publication date: September 20, 2018Inventors: Zhi Cui, Jiansong Wang, Thomas Anschutz
