摘要： A data communications unit determines both efficiently and accurately when one or more data units should be received under a variety of conditions. In particular, the present invention compensates for transmission delays and for varying transmission rates over the communications channel. During a communication between first and second communications nodes, the first node receives a sequence of data units transmitted from the second node. The first communications node determines that one or more of the transmitted data units was either not received at all or was erroneously received (i.e., corrupted). The first node then sends a request to the second node to retransmit the one or more data units not received or erroneously received. A retransmit timer is started when the retransmission request is sent. The retransmit timer accounts for the delay time period required for the retransmit request to reach the second node, for the second node to retransmit the requested data units, and for the retransmitted data units to reach the first node. When the timer indicates that the delay time period has occurred/expired, a counter is started. Based on the counter's value, a determination is made whether all of the data units requested to be retransmitted have been properly received. If the determination indicates that the requested one or more data units has been retransmitted and properly received, no further action is taken. On the other hand, if the requested one or more data units to be retransmitted is not received or is erroneously received, the above-described procedure is repeated.

摘要： The reliability of data communication by is improved analyzing plural data units in a group or a block rather than analyzing individual data units. For example, at the time that a transmitter desires or needs to send a polling request to a receiver, there may be more than one data unit available for delivery as a group. The polling fields of all the data units in this group are set to indicate a poll request. When the receiver receives this group of data units, it sends the requested status information to the transmitter if the polling field of at least one of the received data units in the group indicates a poll request. Moreover, the receiver sends the requested status information only once. Those other polling fields may be used to increase the reliability of the transmission.

A switched domain (5) for transmission of data packets has switches (SW1), to which service providers (1-4), and network terminals (NT1-NT7) are connected.

摘要： In a spread spectrum communications system supporting bursty uplink and downlink data packet transmission telecommunications services, significant concerns exist as to the generation of unacceptable levels of interference resulting from plural and simultaneous data packet transmissions. To address this concern, the system selectively organizes an access schedule for mobile station uplink data packet transmissions and a delivery schedule for downlink data packet transmissions. For the uplink, the schedule is transmitted to plural mobile stations in a current frame, and identifies which one or ones of plural mobile stations are authorized to make an uplink data packet transmission in a next frame. Only those mobile stations scheduled with authorization to make an access in the next frame then transmit their data packets (or a portions thereof) to the base station during that next frame. On the downlink, a notification of intended delivery is communicated to destination mobile stations in a current frame. The system then makes downlink delivery in accordance with the schedule to the destination mobile stations in a next frame.

摘要： The present invention relates to a telecommunication system enabling a user to select services. A telecommunication system having a switched domain comprising switches is disclosed. Service networks are connected to the switches and users are also connected to the switches using fines. An IP path selector and an operator are also connected to the switches. The operator forms service network groups by selecting among the service networks. The service network groups are allocated a virtual local network each by configuring the ports in the switches and the IP path selector. The users can select services by means of selecting one or several of the virtual local networks. By configuring their devices to their chosen virtual local network the user receives the services desired. The user can also change his selection of services by reconfiguring and thus connect to an alternative virtual local network.

摘要： An optimal data block size is determined for use in transmitting data at variable rates over a communications link in predetermined time intervals, where each predetermined time interval has the same time duration. Rather than varying data block size according to changes in transmission rates, which adds unnecessary complexity, the data blocks all have the same fixed size, i.e., the same number of data bits in each block. That fixed data block size is determined so that for all of the available data transmission rates, each predetermined time interval is fully occupied with useful information. The fixed data block size is determined based on a maximum frequency at which the transmission rate may change on the communications link and a lowest available transmission rate. Preferably, the fixed size of each data block is limited by predetermined maximum and minimum data block sizes in order to reduce the number of bit errors per data block, maintain a certain data throughput, and limit the amount of overhead bits relative to the number of payload bits for each data block.
摘要翻译：确定最佳数据块大小用于以预定时间间隔在通信链路上以可变速率发送数据，其中每个预定时间间隔具有相同的持续时间。不是根据传输速率的变化来改变数据块大小，这增加了不必要的复杂性，所以数据块都具有相同的固定大小，即每个块中相同数量的数据位。确定该固定数据块大小，使得对于所有可用数据传输速率，每个预定时间间隔被完全占用有用信息。基于通信链路上的传输速率可能改变的最大频率和最低可用传输速率来确定固定数据块大小。优选地，每个数据块的固定大小被预定的最大和最小数据块大小限制，以便减少每个数据块的位错误数量，保持一定的数据吞吐量，并且限制开销比特数量相对于每个数据块的有效负载比特。

摘要： A scheme to design an audio precompensation controller for a multichannel audio system, with a prescribed number N of loudspeakers in prescribed positions so that listeners positioned in any of P>1 spatially extended listening regions should be given the illusion of being in another acoustic environment that has L sound sources located at prescribed positions in a prescribed room acoustics. The method provides a unified joint solution to the problems of equalizer design, crossover design, delay and level calibration, sum-response optimization and up-mixing. A multi-input multi-output audio precompensation controller is designed for an associated sound generating system including a limited number of loudspeaker inputs for emulating a number of virtual sound sources. Method includes: estimating, for each loudspeaker input signals, an impulse response at each of a set of measurement positions that cover the P listening regions; specifying a target impulse response (target stages) for each virtual sound source at each measurement position; and determining adjustable filter parameters of the audio precompensation controller so that a criterion function is optimized.
