摘要： Each node in a communication system transmits and receives state variable signals indicating internal node states or timings, generates transitions in its internal state or timing at a basic rate but at timings adjusted according to the received state variable signals, transmits data in time slots synchronized to the output state variable signals, receives data signals from the other nodes, detects collisions between the received data signals, and changes the timing of its time slots when a collision is detected, by shifting the phase of the transitions, or by inserting additional dummy transitions and transmitting corresponding dummy output state variable signals. The nodes can thereby assign their own time slots and avoid collisions autonomously.

摘要： In a transmission timing control apparatus, a state variable signal affected by a phase representing the data transmission timing of a neighboring node is used to determine the data transmission timing of the own node. A node information transmitter/receiver transmits source identification information particular to the own node and source node information of a data signal received by the own node, and receives node information transmitted from the neighboring node. A neighboring node information collecting circuit collects neighboring node information of all neighboring nodes having received data signals, based upon the source identification information received by the node transmitter/receiver and the source node information. A collision determination circuit compares in number neighboring nodes to which the transmission timing determining circuit is related as to the control of the data transmission timing with nodes based on the all neighboring node information to determine the probability of a collision between data transmissions.

摘要： A method and a system for providing presence information is disclosed which can incorporate non-presence-ready terminal nodes such as sensor node terminals and combine a plurality of pieces of presence information from a plurality of nodes, thereby providing presence information with improved reliability. The method includes creating circumstance presence information associated with a user in response to a change in value of sensor data transmitted from at least one sensor node terminal. For a presence server to deliver presence information, the method also includes delivering circumstance presence information created in relation to the user either in place of the presence information or in combination with the presence information.

摘要： A transmission timing control apparatus included in a network node constituting a telecommunications system is configured to use the reception timing of a timing signal from another node to determine the transmission timing of a timing signal of the own node and determine a time slot for transmission of a data signal in accordance with the transmission timing and the reception timing of a timing signal from the other node. A response timing signal transmitter transmits a response timing signal when received the timing signal from the other node. A transmission timing control circuit uses the reception timing of the timing signal and that of the response timing signal to determine the timing at which the own node transmits the timing signal.

摘要： Each node on a communication path receives state variable signals from other nodes indicating the internal operating states or internal timing of the other nodes, and transmits a state variable signal indicating its own internal operating state or timing. Transitions in the internal operating state or timing of a node take place at a basic transition rate but at times adjusted according to the state variable signals received from other nodes. The basic transition rate varies according to position on the communication path. The nodes can thereby establish transmitting time slots that follow each other in progression on the communication path, enabling data signals to be relayed from the starting node to the destination node with minimal delay at each intermediate node.
摘要翻译：通信路径上的每个节点从其他节点接收指示其他节点的内部操作状态或内部定时的状态变量信号，并发送指示其自身内部操作状态或定时的状态变量信号。节点的内部运行状态或定时的转换以基本转换速率进行，但有时根据从其他节点接收到的状态变量信号进行调整。基本的转变速度根据通信路径上的位置而变化。因此，节点可以建立在通信路径上进行中彼此相继的发送时隙，从而使数据信号能够以每个中间节点的最小延迟从起始节点中继到目标节点。
