    摘要: The broadband telephony interface is provisioned by receiving information authenticating a provisioning server, establishing a communication channel between the user and the provisioning server over which is transmitted authorization information from the user to the provisioning server, and encrypting and transmitting a cryptographic key associated with the user to the provisioning server. The cryptographic key can be a symmetric key or a public key corresponding to a private key stored in the broadband telephony interface. The cryptographic key can be utilized to generate other keys which are utilized to secure communication channels for the telephony service. The broadband telephony interface advantageously can be implemented as untrusted hardware or software that is installed by a customer.

    摘要: A method and apparatus for anticipating communication interruption. If, during an established call between two communication devices, a telecommunication device determines that a communication link to one of the devices will be interrupted, either temporarily or permanently, the device predicts the interruption in the communication link. The device may send a message, as pre-determined by at least one of the communication device, to the communication device of the predicted or pending call drop or interruption. After the interruption the previously established call is resumed. If a reconnection attempt is appropriate, then the device will attempt to reconnect to the dropped device. If a reconnection attempt is not appropriate, or if the reconnection attempt is unsuccessful, the non-dropped communication device is connected, as predetermined by either of the communication devices, to an appropriate connection, such as, to a voice mail. If the reconnection attempt is successful, the call between the two communication devices is re-established.

    摘要: The present invention permits a network service provider to detect an operational condition—such as congestion—in a packet-switched network and to alleviate such congestion by providing customer incentives to avoid use of the network. The detection mechanism triggers an incentive such as the modification of the user's access charges and the customer can be immediately notified of either the occurrence of the congestion or of information regarding the incentive. Usage of the network during congested periods can be deterred by imposing additional access charges during such periods—similarly, customers can be given a discount to encourage usage during periods of low congestion. An incentive schedule can be tailored to dynamically change the usage patterns of the customers of the network to accommodate the operational conditions in the network. The present invention has application in the Internet, where a detection/notification mechanism, for example, can be implemented in a network node such as a router or in a network endpoint such as a client machine or a proxy or mail server.
