APPARATUS AND METHOD FOR A DEVICE TRANSMITS COMPLEXED C/A CODE SIGNALS OF PSEUDOLITES AND ITS APPLICATION TO AGPS IN MOBILE COMMUNICATION SYSTEMS

摘要

Complex pseudolites signal generator apparatus according to the present invention may jipieseu satellite signal does not reach the installed indoors or underground, that is not the reception of this as a device for providing a jipieseu satellite beacon signals a particular combination in the terminal with Age PS function invention is to generate a unique identification signal (unique Identity signal) with the identifier (unique Identity Element) inherent in a particular manner by mixing said complex signal generator to a plurality of pseudo-satellite-specific pseudo satellite signal internally generated. Specific signal mix of the generating the unique identification signals to generate the combined pseudo-specific (Unique) to different unique identification signal for each combination of a doctor castle signal generator for each satellite signal generator. Position and the unique identifier information of the combination of pseudo-satellite signal generator are stored and managed in the database within the mobile communication system. Thus, the mobile with the age PS function communication terminal is the combination of pseudo-search signals generated by the satellite signal generator, and that when the search results to report to the base station a mobile communication system is distinguished from the search for reporting the terminal result identifier the extracts and find identifying the position of the terminal taking the mounting position of the combination of pseudo-satellite signal generator having a unique identifier extracted from the interior of the database. The present invention provides a PSI Age features of apparatus and method for so identifying the location of a mobile terminal indoors or underground area in this manner. ; Mobile communication systems (Mobile Communication System), decision-satellite (Pseudolite), Interior (Indoor)
