Abstract: In general, the disclosure describes techniques for communicating multicast group leave requests between two or more load-balanced, multi-homed PE routers included in an Ethernet Virtual Private Network (EVPN). The techniques of the disclosure enable the two or more PE routers to synchronize IGMP state and routing information amongst one another to ensure that the one of the multi-homed PE routers elected as the designated forwarder (DF) ceases forwarding the multicast group traffic to the CE router, even if it is not the PE router that receives the IGMP leave request.

Abstract: Methods, systems and devices are provided for presenting event feedback information regarding participants to an event. A first radio of a first participant device carried by a first participant receives a first checkpoint communication from a checkpoint device at a first checkpoint located along a first course of the event. The first checkpoint communication includes a first checkpoint identifier and a first event time reflecting when the first participant crossed the first checkpoint. A first checkpoint event time is determined based upon the first checkpoint identifier and the first event time. Also, the first checkpoint event time is displayed on the first participant device. Further, a checkpoint device and an event server may be used to in presenting the event feedback information.

Abstract: An apparatus and method for adaptively bundling media frames in a data packet for transmission in a wireless data network. When a wireless device is ready to transmit an audio communication, a message is sent from the wireless device to a communication server that checks for network usage conditions and adaptively determines a bundling factor for the audio communication. The bundling factor is transmitted to the wireless device, and the wireless device bundles media frames into a data packet according to the bundling factor.

Abstract: In an embodiment, an application server is configured to manage privacy settings of a subscriber for one or more social networking services. The application server determines a set of privacy settings (e.g., a manually configured or default set of privacy settings) of the subscriber for the one or more social networking services, and then receives, from the subscriber, permission to dynamically modify the set of privacy settings. The application server monitors, responsive to the received permission, passive behavior of the subscriber that is separate from interactions between the subscriber and the one or more social networking services (e.g., calls, text messages, instant messages made to/from the subscriber, a location of the subscriber, etc.). The application server triggers a modification to the set of privacy settings based on the monitored passive behavior of the subscriber.

Abstract: A method and apparatus for providing security in a group communication network provides for receiving an encryption key, encrypting media for transmission to a controller using the received encryption key, the encrypted media being directed to another communication device, and communicating the encrypted media to the controller. In one embodiment, the communicating includes wireless communication. The method and apparatus further provides for receiving encrypted media from a controller and blocking the encrypted media if the communication device is not enabled to receive encrypted-media transmission, or if the media is not encrypted based on an encryption key previously specified by the communication device. In another aspect, the communication device is a push-to-talk (PTT) device.

Abstract: In one embodiment, a method comprises detecting, by a first provider edge router, a second provider edge router providing reachability to a prescribed destination address prefix via a protected next hop address; allocating, by the first provider edge router, a mirror forwarding table associated with the second provider edge router and identifying a destination used by the second provider edge router for reaching the prescribed destination address prefix; and the first provider edge router sending repair information to a Border Gateway Protocol (BGP)-free core network router in the core network, the repair information enabling the BGP-free core network router to add a context label and reroute a received data packet to the first provider edge router if the second provider edge router is unavailable, the context label enabling the first provider edge router to identify the destination in the rerouted data packet for delivery to the destination address prefix.

Abstract: A method for a tracking device optimizing power to remain reachable for a desired period based on evaluated wide-area-network conditions. The tracking device may communicate via a power-intensive long-range transceiver and may continually measure service conditions related to network communications. The tracking device may periodically calculate statistical information describing the service conditions, such as a percentage of time in which the tracking device was out-of-network-service. Based on the statistics, the tracking device may operate in an optimization mode to conserve power when out-of-network-service. In an embodiment, the tracking device may calculate the statistics based on evaluation periods defined by predefined numbers of out-of-network-service occurrences, predefined time periods, and/or a hybrid of both.

Abstract: In one embodiment, a method comprises detecting, by a provider edge router configured for providing reachability for core network traffic to a prescribed destination address prefix, a backup provider edge router relative to the prescribed destination address prefix; allocating, by the provider edge router, a distinct protected next-hop address for reachability to at least the destination address prefix via the provider edge router; and sending via a core network, by the provider edge router, repair information for the prescribed destination address prefix to ingress provider edge routers and a BGP-free core network router in the core network, the repair information enabling the ingress provider edge routers to insert primary and backup switching labels into each data packet of the core network traffic enabling the BGP-free core network router to reroute the received packet to the backup provider edge router if the provider edge router is unavailable.

Abstract: In an embodiment, an originating communication device within a wireless communications system sends a call request to a server to initiate a communication session with a target communication device, and also sends, along with the call request, a session description request, the session description request requesting alerting data to be sent to the target communication device from the server in addition to a call announce message for announcing the communication session to the at least one target communication device, the alerting data describing a nature of the communication session. The server sends the call announce message and the alerting data to the target communication device. The target communication device receives the call announce message and the alerting data, notifies a user of the target communication device of the announced communication session and outputs the alerting data to the user of the target communication device in conjunction with the notification.
