    • PROBLEM TO BE SOLVED: To reduce or eliminate the transmission of the undesired effects of acoustic echo coupling so as to be returned to a reception side and to provide a full duplex connection. SOLUTION: A gain control method is for acoustic echo cancellation and suppression for use with a full duplex voice terminal receiving a far-end signal from a far-end voice terminal and sending a transmit signal to the far-end voice terminal, and the full duplex voice terminal has an adaptive filter, a speaker and a microphone. The method includes: a process of reproducing the far-end signal at the speaker; a process of receiving an echo signal that is acoustically coupled from the speaker to the microphone; a process of filtering the far-end signal by the adaptive filter to generate a filtered signal; a process of calculating an error signal; a process of calculating an attenuation factor from the far-end signal, the filtered signal, and the error signal; and a process of calculating the transmit signal.

    • PROBLEM TO BE SOLVED: To provide a packet encryption method wherein the computation time for encryption/decryption is reduced, and packets can be recovered even when the packets are lost.
      SOLUTION: The efficient packet encryption method includes: a step of creating an S-vector; a step of setting a sequence number; a step of setting a first variable; a step of setting a second variable; a step of setting a byte sequence number; a step of calculating a third variable from the second variable and the byte sequence number; a step of incrementing the byte sequence number; a step of calculating a fourth variable by adding the value within the S-vector pointed to by the third variable to the first variable; a step of specifying an encryption byte based on the value within the S-vector pointed to by the third variable and the fourth variable; and a step of exclusive ORing to generate the byte.

    • A classification mechanism automatically aligns time-sensitive data streams to sequences (schedules), according to information in the packets or other information and classification criteria specified by a human network administrator, a sequence agent, an application program or otherwise. When a packet arrives at a first sequence-aware switch along a path, the packet is aligned to a new or existing sequence. When a new sequence is established, appointments are reserved at sequence-aware switches along the path. The packet is placed in a queue, based on its classification. When the packet reaches the head of the queue, at that queue'’ appointment time, the switch forwards the packet along the path. If possible, appointments have been reserved at subsequent switches along the packet’s path, so the packet can be forwarded through the subsequent switches without delay. Packets that do not match any classification criteria are handled on a best-effort basis.
    • 分类机构(202)根据分组中的信息或由人网管理员,序列代理,应用程序或其他方式指定的其他信息和分类标准自动对准时间敏感数据流到序列(调度)。 当分组沿着路径到达第一序列感知交换机(212)时,分组与新的或现有的序列(208或214)对准。 当建立新的序列时,沿路径的顺序识别交换机保留约定。 基于其分类将分组放置在队列(208或214)中。 当数据包到达队列的头部时,在该队列的“约定时间”中,交换机沿路径转发数据包。 如果可能,沿着分组的路径在后续交换机(204或206)处保留约定,因此可以不延迟地通过后续交换机转发分组。

    • A method and apparatus are disclosed for delivering enhanced messages to a calling party. A message document address is provided to the calling party that is a pointer or hyperlink to a message document containing a message for a calling party, such as a uniform resource locator (URL) identifying an Internet document. The calling party may receive a message, e.g., when the called party is not available or containing a list of user-specific menu options in an IVR system. The message document can be (I) a static document created; (ii) a default document created; (iii) a dynamically generated document based on one or more rules that alter the content of the document based on various characteristics of the calling party or the call (or both). The presentation of the message document address to the user can be conditioned upon the satisfaction of one or more rules, such as when the called party is unavailable or based on one or more predefined characteristics of the calling party or the call (or both).
