  • Publication number: 20080305763
    Abstract: Methods and apparatus for use in processing disconnected emergency calls and other communications involving mobile communication devices, as well as the remote monitoring of such mobile communication devices, are disclosed. In one illustrative example, an emergency call with a public safety answering point entity is established by a mobile communication device via a wireless communication network. If the emergency call is disconnected, the mobile device monitors to receive an incoming call message for a continued emergency call from the public safety answering point entity. In response to receiving such incoming call message, the mobile device refrains from producing an audible alert and automatically answers the continued emergency call from the public safety answering point entity without detecting any manual answer signal via its user interface.

  • Patent number: 6785291
    Abstract: A technique for dynamically assigning a packet flow to transmission channels can result in more efficient use of the channels when compared to static assignment techniques. Using this technique for dynamic assignment, an initial channel assignment is made based upon a channel specification corresponding to a flow classification indication within the first packet of the flow. Subsequently, the flow classification indications of further packets within the flow are monitored for changes. If it is detected that a flow classification indication has changed when compared to the previous flow classification indication, it is determined whether the previous channel assignment satisfies a channel specification corresponding to the new flow classification indication. If it is determined that the previous channel does not satisfy this new channel specification, a modified channel assignment is generated for the subsequent packets of the flow.
