    • PURPOSE: A method and an apparatus for controlling TDMA network synchronization by using a loopback are provided to prevent burst collision and accurately transmit a burst at allocated timing. CONSTITUTION: A traffic earth station obtains Dn through an RB(Reference Burst) received from a reference earth station after satellite delay time(16), and calculates TBT(Transmit Burst Timing) by using Dn(17). The traffic earth station transmits an initial TB at time allocated by a satellite A traffic base station transmits an SB(Short Burst), generating a timing margin as much as (TB-SB), and calculates a TBT again by allocating the timing margin by half before and after a burst(18). The traffic base station transmits the SB at an early stage by using the obtained TBT(19). After the satellite delay time, receive timing of the SB is calculated after an RFT to obtain an RBT(Receive Burst Timing)(6). The traffic earth station stores its TB-allocated timing as a BTF information in a memory, and obtains an error between the RBT value and the BTP value(8). A TBT can be obtained by subtracting the error value from the previous TBT value.
    • 目的:提供一种通过使用环回来控制TDMA网络同步的方法和装置,以防止突发冲突,并在分配的定时精确地发送突发。 构成:地面站通过在卫星延迟时间(16)之后从参考地球站接收的RB(参考突发)获得Dn,并使用Dn(17)计算TBT(发送突发时间)。 业务地球站在由卫星A分配的时间发送初始TB业务基站发送SB(Short Burst),产生与(TB-SB)一样多的定时余量,并通过分配时间裕度来再次计算TBT 爆发前后一半(18)。 交通基站通过使用获得的TBT(19)在早期发送SB。 在卫星延迟时间之后,在RFT之后计算SB的接收定时以获得RBT(接收突发定时)(6)。 业务地球站将其作为BTF信息的TB分配定时存储在存储器中,并且获得RBT值和BTP值之间的误差(8)。 可以通过从先前的TBT值中减去误差值来获得TBT。

    • PURPOSE: This invention relates generally to packet-switching systems, such as asynchronous transfer mode(ATM) systems, and specifically to transmission-delay variations in such systems. CONSTITUTION: An ATM cell constructor(100) of an ATM transmitter assembles a stream of frames of constant bit-rate traffic received on a listen TDM bus(102) into cell payloads(1104) using ATM adaptation layer 1(AAL1). Once every eight cells, the AAL1 structured data transfer(SDT) cell constructor layer(112) introduces a one-octet SDT offset pointer(1120) into the payload. This pointer designates traffic-block(TDM frame) boundaries. The payload with an attached ATM header forms an ATM cell, and the constructor transmits a stream of the ATM cells, carrying traffic of one wideband channel, to a receiver. A receiver receives one or more streams of the ATM cells from one or more transmitters. During each frame interval, an ATM cell deconstructor(2100) of the ATM receiver disassembles a block's worth of traffic from a received ATM cell of each received stream, assembles the disassembled traffic from every stream into a TDM frame, and transmits the frame on a talk TDM bus(102). In response to commencing to disassemble a whole block's worth of traffic from an ATM cell that includes the SDT offset pointer, the deconstructor adjusts the disassembling to commence the disassembling of the whole block's worth of traffic at the block boundary pointed to by the SDT offset pointer, thereby aligning frames on the talk TDM bus with the frames on the listen TDM bus. The listen and talk TDM buses are thereby synchronized with each other.
    • 目的:本发明一般涉及分组交换系统,例如异步传输模式(ATM)系统,具体涉及这种系统中的传输延迟变化。 构成:ATM发送器的ATM信元构造器(100)使用ATM适配层1(AAL1)将在监听TDM总线(102)上接收的恒定比特率流量的帧流组合成小区有效载荷(1104)。 每八个单元一次,AAL1结构化数据传输(SDT)单元构造器层(112)将一个八位位组SDT偏移指针(1120)引入有效载荷。 该指针指定业务块(TDM帧)边界。 具有连接的ATM报头的有效载荷形成ATM信元,并且构造器将携带一个宽带信道的业务的ATM信元的流发送到接收机。 接收机从一个或多个发射机接收一个或多个ATM信元流。 在每个帧间隔期间,ATM接收器的ATM信元解构构件(2100)从每个接收到的流的接收的ATM信元中分解块的数据流,将从每个流的分解业务组装成TDM帧,并将帧发送到 谈TDM总线(102)。 响应开始从包含SDT偏移指针的ATM信元拆卸整个块的流量,解构器调整拆卸,开始在SDT偏移指针指向的块边界处对整个块的流量进行拆卸 从而将通话TDM总线上的帧与监听TDM总线上的帧对准。 听和说的TDM总线由此彼此同步。
