  • Patent number: 7773517
    Abstract: A method and device for identifying degradation in service quality for a wireless media service. The wireless media service has a known expected packet generation rate, which may be determined by the device based upon the codec and payload size selected on initiating the media service. At a receiving device, the packets actually received by the device from the other termination point are counted over a time period, and this number is compared with the number of packets that were expected based upon the known packet generation rate. From this comparison a packet loss rate may be determined. If the packet loss rate exceeds a threshold level, then the device may issue a user alert, terminate the service, or take other action. The threshold level may be established based upon a packet loss rate corresponding to a significant degree of service quality degradation.

  • Patent number: 7676215
    Abstract: An emergency routing number is assigned to each switch in a wireless network. When a switch of the wireless network routes an emergency call to a Public Service Answering Point (PSAP), the switch sends the emergency routing number as the calling party number and provides the PSAP with the identifier of the mobile station. If the emergency call drops, the PSAP performs a call back using the emergency routing number as the called party number. The switch that routed the emergency call from the mobile station to the PSAP receives the call back. The PSAP also sends the identifier of the mobile station to the switch. When a switch receives its emergency routing number as the called party number, the switch recognizes an emergency call back situation and pages the mobile station identified by the mobile station identifier received in association with the emergency routing number. The mobile station is then reconnected with the PSAP.

  • Patent number: 7574174
    Abstract: An apparatus, method, and system for a remote-page devices. Communications are made more efficient with a connectivity tool. Remote-page enabled clients allow a short-range RF device to communicate beyond its coverage area or that of a nearby access point. Such a remote-page enabled client may issue remote-page messages and send them to remote-page enabled access points, which will ultimately route the message to a desired target client beyond the coverage area of the original client. The disclosure further teaches a remote-page enabled access point that may accept remote-page messages from clients and pass them on to remote access points that are communicating with the desired target device. The disclosure also teaches a remote-page server that tracks specified remote-page enabled access points and all clients disposed in communication with the access points.

  • Patent number: 7565106
    Abstract: A wireless signal repeater will function to boost the strength of signals being communicated wirelessly between a base station and a mobile station. At the same time, however, the wireless signal repeater will read control channel messages transmitted by the base station and will obtain from the messages an indication of outside temperature and an indication of local time. The repeater will then display the outside temperature and local time information for viewing by a user. Advantageously, the repeater will thus become a more functional object in the eyes of the average lay-person, rather than functioning merely to boost wireless signal levels.
