摘要： A technique is disclosed that attempts to improve the evaluation of a network path's signal quality, as well as the selection of a network path for transmission purposes, without some of the costs and disadvantages of doing so in the prior art. In accordance with the illustrative embodiment, a node with access to the packet network, such as a VoIP telephone endpoint, evaluates the quality of service that is associated with each of multiple network paths. The evaluation process is iterative, in which the number of candidate paths is successively reduced from one iteration of the technique to the next. The multiple paths that remain as candidates in any given iteration are evaluated concurrently and at an evaluation bit rate that i) is less than the full transmission rate of the real-time traffic (VoIP) packets to be sent and ii) varies as a function of the number of candidate paths remaining under consideration.

摘要： A method and apparatus are disclosed for redirecting traffic associated with an application so that the traffic advantageously traverses (or “hairpins”) through an application-layer gateway. Because the present invention advantageously redirects traffic without any participation by routers, no changes to or replacement of routers in a network is required. The illustrative embodiment is disclosed in the context of Internet telephony, but is also applicable to other kinds of applications and types of communication (e.g., Internet Protocol Television [IPTV], instant messaging [IM], videoconferencing, etc.)

摘要： A method that seeks to provide a satisfactory quality of service for a stream of packets through a network. The illustrative embodiment of the present invention seeks to provide a satisfactory quality of service for a stream of packets by periodically or sporadically evaluating one or more alternative paths through the network and by sending the packets through a path with an acceptable quality of service. Normally, neither the source node nor any other node in a packet's path controls its route after it has left the node. In contrast, the illustrative embodiment of the present invention has the capability to affect the packet's path through the network by sending the packet to an intermediate or “ricochet” node in the network, which forwards the packet to the destination node. In effect, the source node can, if it deems appropriate, ricochet the packet off of the intermediate node rather than allowing the packet to take its normal direct path through the network.
摘要翻译： 一种寻求通过网络为数据包流提供令人满意的服务质量的方法。 本发明的说明性实施例旨在通过周期性地或偶尔地评估通过网络的一个或多个替代路径以及通过具有可接受的服务质量的路径发送分组来为分组流提供令人满意的服务质量。 通常，分组路径中的源节点和任何其他节点都不会在离开节点后控制其路由。 相比之下，本发明的说明性实施例具有通过将分组发送到网络中的中间或“弹射”节点来影响分组通过网络的路径的能力，该节点将分组转发到目的地节点。 实际上，如果源节点认为合适，则可以使分组从中间节点跳出，而不是允许分组采用其通过网络的正常直接路径。

摘要： A method and apparatus are disclosed for estimating the location of a wireless terminal across multiple building floors. The illustrative embodiment determines the floor where the wireless terminal is presently located by using a majority logic-based heuristic. A plurality of signal monitors measure signals from the wireless terminal and provide those signal strength measurements to a location estimation server. Alternatively, the wireless terminal measures signals that are transmitted by a plurality of transmitting signal devices and provides those signal strength measurements to a location estimation server. The location estimation server determines the floor of the wireless terminal in accordance with the illustrative embodiment of the present invention.

摘要： A method and apparatus are disclosed that enable a data-processing system, such as a server, to determine whether or not to grant a telecommunications terminal one or more privileges, without some of the disadvantages of the prior art. Specifically, in accordance with the illustrative embodiments of the present invention, a call-processing server transmits, to a first terminal, a first signal for verifying a second terminal, such as one that has been designated by a user. The user is then required to transmit a second signal to the call-processing server via the second terminal. The call-processing server then examines the received second signal with respect to the first signal and determines whether or not to grant the second terminal a privilege (e.g., handling calls on behalf of the user, etc.), based on the relationship between the first and second signals.

摘要： An apparatus and method are disclosed that enable a terminal such as a computer-based softphone to retrieve and handle, transparently for its user, the voicemail that has been left by calling parties who called the user's cell-phone number. Furthermore, the softphone is able to integrate the presentation to its user of the voicemail associated with the cell phone with the voicemail that has been left by calling parties who called the softphone itself. The softphone features both i) a personal area network interface that is used to communicate directly with the cell phone and ii) a local area network interface that is used to retrieve the cell-phone voicemail from a voicemail system. Once the softphone is paired with the cell phone, the softphone is able to retrieve signals directly from the cell phone and, based on those signals, retrieves the voicemail from the cell phone's voicemail system.
