  • Patent number: 7650143
    Abstract: An apparatus for providing connectivity is provided that includes a mobility server operable to coordinate a communication session between a first and a second end-user device. The first end-user device is associated with a first call leg and the second end-user device is associated with a second call leg. A handoff is executed in transferring the communication session from the first end-user device to the second end-user device. In more particular embodiments, the mobility server is operable to receive signal strength information from the first end-user device and to execute the handoff based on the signal strength information. In addition, the handoff is executed based on an end-user preference that is provided in a subscription that is accessed by the mobility server.

  • Publication number: 20090325582
    Abstract: Gathering location information from a first wireless network to determine whether to anchor a communication session in a second wireless network, a mobile node capable of communicating with both the first wireless network and the second wireless network, includes receiving location information from the first wireless network as the mobile node moves through one or more service areas of the first wireless network. It is determined whether a triggering event occurs. If the triggering event occurs, the location information is stored to determine whether to anchor a session in the second wireless network.

  • Patent number: 7586852
    Abstract: Devices, software, and methods measure a burstiness of packet loss episodes in transmissions of voice data through networks. At least one burstiness statistic is determined to quantify how the lost packets are distributed with respect to the received packets within the sequence. The burstiness statistic is optionally used to determine a figure of merit, which in turn can be used to give a grade for predicting how well a packet loss concealment scheme will work.
