Abstract: Synchronizing local timing units to a central timing unit to determine the difference in timing between external links and the local timing units so as to synchronize the centralized timing unit to the external links. This difference in timing is then transmitted to the central timing unit, which utilizes this information to adjust the timing of the central timingunit. The adjustment to the central timing unit brings it into synchronization with the selected external link. The local timing units are synchronized to the central timing unit via multiple timing paths set up through switching units within the network. Each switching unit switches one bit of data for each group of data being received on each of the external links. In addition, information received by each of the external links designating the accuracy of the external link is transmitted to the central timing unit so that the central timing unit can select the external link having the highest accuracy.

Abstract: Symbol 102 that is spread with the only short spreading code and inserted in synchronism with a long spreading code is specified by detecting the correlation with only the short spreading code. Next, another short spreading code indicative of a timing of reverse and forward link switching is specified, where the short spreading code is multiplexed at the same position as that of the detected symbol. The detection of the symbols spread with only these spreading codes enables to acquire synchronization of the long spreading code, synchronization of switching of reverse and forward links, and synchronization of a transmission frame. It is thereby possible to reduce synchronization acquisition time for the long spreading and an easy planning of base station locations without decreasing the frequency utilization efficiency.

Abstract: A method and apparatus for synchroniza-tion between a base station sub-system (250) and a mobile station (200). The mobile station (200) listens for a message frame number which is generated by the base station sub-system (250). The mobile station (200) includes a mo-bile frame number counter (280) which tracks the progression of frame numbers. When first powered-up, the mobile frame number counter (280) may not be synchronized with the base station sub-system (250). The frame numbers of the base station sub-system (250) and the mobile frame number counter (280) values are continuously incremented to track the progres-sion of frame numbers in real-time. To ef-fect synchronization, a received and decoded frame number is loaded into the counter (280).      Then, a time-lag is calculated which repre-sents the delay inherent in receiving and de-coding, within the mobile station and its com-ponents, frame numbers from the base station sub-system (250). The time lag is then added to the mobile frame number counter (280) of the mobile station so that the mobile frame number counter is synchronized with the base station sub-system (250).
