摘要： Latency in receiving and detecting paging messages at a wireless terminal is reduced by employing a unique nullsupernull paging time slot format. A paging super time slot includes a plurality of prescribed time slots. Each wireless terminal is associated with cyclically recurring super time slots. A super slot is associated with one or more wireless terminals. A base station always selects the first available time slot in a super time slot to transmit a paging message to a wireless terminal that is associated with the super time slot. Each wireless terminal monitors every time slot in the associated super time slot until either detecting reception of its associated paging message or detecting an empty time slot. In another embodiment of the invention, a unique partially overlapping super time slot format is employed in which a super time slot has at least one time slot common to its adjacent super time slots. This allows wireless terminals associated with adjacent super time slots to share the common at least one time slot. In turn, this results in balanced traffic loads, smoothed traffic fluctuation and reduced congestion.

摘要： A method for scheduling data bursts from origin to destination nodes of a communication system involves selecting a yet-unscheduled, feasible node pair for scheduling of a burst therebetween; selecting a timeslot from a finite timeslot sequence; scheduling the burst for the selected timeslot; and repeating the preceding steps to exhaustion of unscheduled demand or of feasible node pairs. The feasibility of a node pair is conditioned on the avoidance of collisions with already-scheduled bursts, taking the various origin-to-destination propagation delays into account.

摘要： A single-wire serial communications bus has a master device and one or more slave devices. The slave devices are addressed according to a predetermined addressing scheme in an address space. The master device starts a transmission with a number of line state changes which define a clock period to be used by the slave devices in clocking and framing the serial data. This permits omitting a clock line, thus saving a pin and saving printed circuit board space. This also permits the slave devices to shut down their own clocks during periods of inactivity on the bus, thus saving power. Likewise the master device is able to shut down its clock during periods of bus inactivity.

摘要： A network, such as a radio network, uses dynamic transmission scheduling and soft clustering. When nodes contend for data slots, each node that is successful continues to have its data slot reserved for it until it sets an end-of-stream bit in an information summarization packet, indicating that it will stop broadcasting. From the information summarization packets, each node determines the other nodes to which it will listen, based on proximity and information content.

摘要： Assigning inbound ringing ISDN channels to a particular endpoint's call uses a framing listening technique to distinguish between H.221 framing, master bonding channel framing and slave bonding channel framing. If the channel is receiving Master Bonding Channel framing, the MCU detects that this is a new call from a unique far endpoint and may then begin a process to address this new call. If the channel is receiving Slave Bonding Channel framing, the MCU then transmits a multi-frame pattern and looks for a Physical Video Unit Identifier the MCU sent to this far end via the Master Channel upon initial negotiation. If the channel is receiving H.221 framing, a H.243 terminal address assigned using a Terminal Indicate Assignment (TIA) message in the initial channel is used. The far endpoint may then send this address in its additional channels through the use of a Terminal Indicate Additional Channel X (TIX) message. The MCU may associate an incoming channel to the correct call by examining the address sent by the far endpoint in the TIX message. In the case of simultaneous calls according to the H.323 protocol, the process retains the incoming H.323 call in the current state (i.e., Alerting/Incoming Ringing State), and waits until the current call progresses to a state Call Connected, after which the incoming call may be allowed to be answered and transitioned to its Call Connected state. This may be done without hanging up the incoming call with a busy indication.
摘要翻译：将入站响铃的ISDN信道分配到特定端点的呼叫使用成帧侦听技术来区分H.221成帧，主接合信道成帧和从属绑定信道成帧。如果信道正在接收主绑定信道成帧，则MCU会检测到这是一个来自唯一远端点的新呼叫，然后可以开始处理这个新呼叫的过程。如果信道正在接收从绑定信道成帧，则MCU然后发送多帧模式，并在初始协商时寻找通过主信道发送到该远端的物理视频单元标识符。如果信道正在接收H.221帧，则使用在初始信道中使用终端指示分配（TIA）消息分配的H.243终端地址。然后，远端点可以通过使用终端指示附加信道X（TIX）消息在其附加信道中发送该地址。 MCU可以通过检查TIX消息中的远端点发送的地址来将输入信道与正确的呼叫相关联。在根据H.323协议进行同时呼叫的情况下，该过程将保持传入的H.323呼叫处于当前状态（即，告警/接收振铃状态），并等待直到当前呼叫进入呼叫连接状态，之后可以允许来电接听并转换到其呼叫连接状态。这可以在没有挂起来电的忙碌指示下完成。

摘要： Techniques for rescheduling one or more timing intervals associated with a channel of a communication system. Responsive to a detected change in a property of the channel, a rescheduling algorithm identifies a given one of the timing intervals, within a schedule for the channel, that violates a system requirement in view of the detected change. The algorithm determines if the interval can be rescheduled to accommodate the detected change and if so reschedules the interval. If the interval cannot be rescheduled to accommodate the detected change, the interval is removed from the schedule. The rescheduling process may be repeated for each of the intervals in the channel schedule. The intervals in an illustrative embodiment may include, for example, grants, polls, free intervals or initial-maintenance intervals (IMIs) of an upstream channel in a DOCSIS-compliant CATV system.

摘要： The present invention relates to a method for resolving a collision in a communication system using medium access control based on contention. The method of the present invention enables management and control of a contention window size of each mini slot and thus all the terminals may have an equal opportunity to access each mini slot. Moreover, when two or more terminals have simultaneously attempted to access any one mini slot and thus collision has occurred in the mini slot, the method of the present invention restricts the access of the mini slot to the terminal or terminals that had experienced collision, and then permits an access attempt of another terminal after all the terminals which had experienced collision succeed in accessing a mini slot.
