  • Publication number: 20220159067
    Abstract: Connecting user equipment (UE) to an application can be managed based on UE movement and location. During data session between UE and application, a communication management component (CMC) associated with anchor network component (ANC) or serving network component (SNC) determines UE location, and connects UE to the ANC and SNC, which enables access of the application via a data network associated with ANC. As UE moves, CMC tracks UE movement and communication conditions. If, when UE is at second location, a communication condition breaches threshold level, CMC determines whether interruption of the data session is permitted. If not, CMC determines whether there is a local SNC in proximity to second location. If there is, CMC can switch UE from SNC to local SNC, which can access local application content via local data network associated with application. If interruption permitted, UE deactivates and reactivates to connect to local ANC.

  • Patent number: 11284455
    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.

  • Patent number: 11153802
    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.

  • Publication number: 20210243675
    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.

  • Publication number: 20210218691
    Abstract: Concepts and technologies disclosed herein are directed to application-based multiple radio access technologies (“RAT”) and platform control using software-defined networking (“SDN”). According to one aspect of the concepts and technologies disclosed herein, an SDN controller can configure a radio access network (“RAN”) for connectionless services and for connection-oriented services. The RAN can support multiple RATs each capable of providing radio access to a device, such as a UE or an IoT device. The SDN controller can determine a user plane path configuration for an application flow through at least part of the RAN. The SDN controller can provide the user plane configuration to an SDN agent that is stored on and is executable by the device.

  • Patent number: 11039291
    Abstract: Node identifiers can be assigned to packet core policy nodes and directly routed to a diameter routing agent (DRA) and application functions (AFs) within a call processing message that is employed to establish an application service. Such a policy node identity will be received by Application Functions, UEs and/or intermediate message routers during the initial establishment of a packet data session so that they can refer to the policy node entity directly in the sub-sequent call processing flows related the established session, instead of querying a relational database which can be complex to maintain with multi-million correlation records. As an example, the policy node identifiers can be configurable and can comprise a hostname of the policy nodes, address data associated with the policy nodes, or a defined numerical value that maps to the hostname of the policy nodes.

  • Patent number: 10966065
    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.
