Computer-readable media and systems for communicating physical gestures as compressed data streams are provided. In particular, a technique is employed for generating replicated physical gestures on a user-interface display to visibly communicate sign language without transmitting information standard to typical video sessions, such as audio or video frames. In general, the technique entails the following steps: receiving coordinate representations of user-initiated physical gestures (e.g., hand movements); deciphering the received coordinate representations to identify corresponding motion patterns; and conveying the motion patterns to a presentation component for rendering. Rendering involves replicating the physical gestures by providing animations that carry out the motion patterns. The coordinate representations are generally received from a mobile device that captures physical gestures of a sender by employing a position-tracking interface. Upon capturing the physical gestures, the mobile device maps the coordinate representations to the physical gestures and records/transmits the coordinate representations at a high-speed frame rate.

Methods and systems for providing proximate-and-active-emergency-vehicle notifications to mobile-device users are provided. The emergency vehicle may become active, and its location and status may be received by a network element. A mobile-device user's location may also be received by a network element. It may be determined based on analyzing the location of the emergency vehicle and the location of the mobile-device user to provide the mobile-device user with a proximate-and-active-emergency-vehicle notification.

Methods and systems for a wireless communication device (WCD) to change a media session codec prior to handoff to a new wireless coverage area are presented. In particular, a WCD is served by a first wireless coverage area of a RAN, and is conducting a media session using a first codec. The WCD detects that it is about to be handed off to a second wireless coverage area, and transmits a request to a server to determine the capacity available to the WCD via the second wireless coverage area. If this capacity is less than the capacity request by the first codec, the WCD proactively renegotiates the media session to use a second codec that requires less capacity. The server may take various factors into account when responding to the WCD's query, including the sector loading of the second wireless coverage area, available capacity at a backhaul link between the RAN and a network, and/or a profile of the WCD.

An end-to-end virtual private networking system transports network packets securely through a public data network. A mobile device comprises an application client and a wireless roaming client managing data transfer from the mobile device to the public data network via one of a plurality of predetermined wireless links. A roaming gateway is located in a data center and is coupled to the public data network for tracking the plurality of predetermined wireless links and for managing data transfer from the public data network to the mobile device via one of the plurality of predetermined wireless links. An enterprise server is provided in a private enterprise for exchanging network packets with the application client in the mobile device. A CPE-VPN router in the private enterprise network is coupled to the enterprise server and to the public data network. A VPN router located in the data center is coupled to the roaming gateway and to the public data network, wherein the VPN router and the CPE-VPN router establish a VPN tunnel therebetween via the public data network. The CPE-VPN router transports the network packets between the enterprise server and the VPN tunnel. The VPN router transports the network packets between the roaming gateway and the VPN tunnel.
