Abstract: Embodiments include receiving one or more packets of a Wi-Fi calling session via a secure tunnel from a user device, where the user device is connected to a source network via a Wi-Fi access point. Embodiments also include determining whether the Wi-Fi calling session is a threat based, at least in part, on identifying an anomaly of at least one packet of the one or more packets. An action can be taken if the Wi-Fi calling communication is determined to be a threat. More specific embodiments include determining the at least one packet is associated with the Wi-Fi calling session by correlating information in the packet with control plane data of the Wi-Fi calling session. Further embodiments can include intercepting the one or more packets in a second secure tunnel established between an evolved packet data gateway and a service provider network associated with the user device.

Abstract: Systems and methods for providing load based optimizations in communication networks are provided. A network device that provides network management and exchanges control messages with other network devices in the communication network can be modified to masquerade as a radio access transceiver to obtain radio access transceiver load information. The network device can be modified to include a radio-related interface and can communicate messages with the radio access transceivers to setup a radio access transceiver connection for exchange of load information. The radio access transceiver load information can then be used in the core network to provide optimizations for the loaded radio access transceivers. The optimizations can include modifying packet flows to decrease the bandwidth needed and switching one or more packet flows to another radio access transceiver.

Abstract: Systems and methods for small cell idle mode mobility include receiving, at a first small cell of a preconfigured cluster of small cells, a mobility area update request from a user equipment (UE). The method can also include registering location information of the UE with a small cell gateway, and retrieving a core network periodic timer for the UE from a mobility server. If certain conditions are met, the first small cell forwards the mobility area update request to a core network via the small cell gateway. Otherwise, the method can include the first small cell updating the location information of the UE with the mobility server, generating a locally-generated mobility area update accept message, and sending a locally generated mobility area update accept message to the UE along with a local periodic timer instructing the UE to send another mobility area update request when the local periodic timer expires.

Abstract: Systems and method are provided that allow an application layer client in a mobile device to manage multiple interfaces in a communication network. The multiple interfaces can include WiFi, cellular, Femto, WiMAX, Bluetooth, infrared, Ethernet, and other types of interfaces for communication in a network. The client on the mobile device can use intelligence and rules to determine how and when request fragments are communicated over the various interfaces available to the client. The intelligence can include parameters such as performance information for a particular interface and subscriber preferences. Based on this information the client can decide to use a combination of the interfaces to obtain multimedia content and render the content for display on the mobile device. By using a combination of interfaces and tracking the advantages and disadvantages of each interface, the client can make intelligent decisions in providing multimedia content to the user.
