    • A method is disclosed for operating a synchronous Code Division Multiple Access (S-CDMA) radio frequency communication system having a host transceiver unit and a plurality of user transceiver units. The method includes an initial step of defining a super-frame to be comprised of N sequential frames of data. In the preferred embodiment N is equal to three. For a user transceiver unit that obtains access to the host transceiver unit a next step of the method receives frames of data transmitted by the host transceiver unit and initially aligns a receiver timing and a transmitter timing of the user transceiver unit to a super-frame boundary of the received frames. A next step transmits frames of data from the user transceiver unit to the host transceiver unit using the initial timing alignment. A further step of the method detects at the host transceiver unit a difference between the arrival of the transmitted frames of data and a super-frame boundary and then transmits a timing correction parameter, preferably expressed in symbols, from the host transceiver unit to the user transceiver unit in order to align the transmitted frames of data to the super-frame boundary.
    • 公开了一种用于操作具有主机收发器单元和多个用户收发器单元的同步码分多址(S-CDMA)射频通信系统的方法。 该方法包括定义由N个连续数据帧组成的超帧的初始步骤。 在优选实施例中,N等于3。 对于获得对主收发器单元的访问的用户收发器单元,该方法的下一步骤接收主机收发器单元发送的数据帧,并且最初将用户收发器单元的接收机定时和发送器定时对齐到超帧边界 的接收帧。 下一步骤将使用初始定时对准将数据帧从用户收发器单元发送到主机收发器单元。 该方法的另一步骤在主机收发器单元处检测所发送的数据帧的到达与超帧边界之间的差异,然后将来自主收发器单元的优选地以符号表示的定时校正参数发送到用户 收发器单元,以便将发送的数据帧对齐到超帧边界。

    • Apparatus for determining a protocol of messages traversing a signalling link in a telecommunications network includes a memory for storing one or more predetermined characteristic of a message in the protocol that can be used to distinguish that protocol from other protocols. A protocol auto-discovery module is coupled to the memory and to a module that extracts channels from signalling link timeslots. The protocol auto-discovery module determines whether the predetermined characteristic is present in the sampled message and identifies the signalling link as carrying messages in the particular protocol if the predetermined characteristic is present in the sampled message. The identification may be based on a confidence measure stored in a channel configuration table which is incremented when a message on the signalling link is identified as being in that particular protocol and decremented when a message is identified as being in another protocol.
    • 用于确定通过电信网络中的信令链路的消息的协议的装置包括存储器,用于存储协议中可用于将该协议与其他协议区分开的协议中的消息的一个或多个预定特性。 协议自动发现模块耦合到存储器和从信令链路时隙提取信道的模块。 如果在采样消息中存在预定特性,则协议自动发现模块确定采样消息中是否存在预定特性,并将信令链路识别为携带特定协议中的消息。 识别可以基于存储在信道配置表中的置信度度量,当信令链路上的消息被识别为处于该特定协议中时,信道配置表被递增,并且当消息被识别为处于另一协议时递减。
