  • Publication number: 20200178149
    Abstract: The described technology is generally directed towards selectively steering wireless network data packet traffic to a network edge cloud, which reduces backhaul bandwidth and facilitates ultra-low latency communications. In one aspect, upon receiving a request for data communication by a user equipment in the wireless network, location information is used to override a centralized access point name (e.g., 4G serving gateway/packet gateway, S/PGW, or 5G user plane function) with an edge-located access point name (edge 4G S/PGW or edge 5G user plane function). This facilitates the data communication between the user equipment and an edge-located access point device associated with the edge-located access point name.

  • Publication number: 20200145902
    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.

  • Patent number: 10609590
    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.

  • Publication number: 20200084597
    Abstract: Tracking areas that comprise service cells capable of providing advanced long-term evolution (LTE-A) features, can be utilized to indicate to a mobile device that the mobile device can access the advanced features. For example, an LTE-A capable mobile device can display an LTE-A icon if the mobile device is in a geographic area that qualifies as an LTE-A tracking area. However, if the mobile device is not capable of receiving LTE-A services, then the mobile device can display an LTE icon instead of an LTE-A icon.

  • Patent number: 10574568
    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.

  • Patent number: 10575218
    Abstract: Aspects describe renegotiation of quality of service parameters to resolve maximum bit rate mismatches and/or other quality of service parameter mismatching issues that might arise during an inter-radio access technology handover. At about the same time as a mobile device moves from a source network to a target network, the target network dynamically initiates a quality of service modification procedure. The quality of service modification procedure can help resolve the maximum bit rate mismatches and/or the other quality of service parameter mismatching issues.

  • Publication number: 20200037377
    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.

  • Publication number: 20190357113
    Abstract: Aspects of the subject disclosure may include, for example, a device that determines each of a default downlink forwarding address of a first interface of a user plane and a currently used downlink forwarding address of the first interface of the user plane. One of an uplink user data packet comprising an origination address of a second interface of the user plane, a downlink user data packet comprising a destination address of the second interface of the user plane or both are received, by way of the user plane. One of the default downlink forwarding address, the currently used downlink forwarding address or both can be modified based on the uplink origination address, the destination address or both. Modification of the default downlink forwarding address, the currently used downlink forwarding address or both results in a redirection of an associated packet flow within the user plane. Other embodiments are disclosed.

  • Patent number: 10470099
    Abstract: Aspects of the subject disclosure may include, for example, 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 transfer 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.

  • Patent number: 10375528
    Abstract: Dynamically switching between broadcast and unicast services for service continuity between wireless networks is presented herein. A system can comprise a detection component configured to determine that a mobile device is receiving a broadcast transmission of broadcast data from a broadcast enabled access point device configured to send, via a broadcast service wireless coverage area, the broadcast data to multiple devices via a point-to-multipoint communication protocol. Further, the detection component can detect a movement of the mobile device from the broadcast service wireless coverage area to a unicast service wireless coverage area. A transfer component can initiate, in response to the detection, a unicast transmission of the broadcast data from a unicast enabled access point device to the mobile device—the unicast enabled access point device configured to send, via the unicast service wireless coverage area, the broadcast data to a single device via a point-to-point communication protocol.
