ABSOLUTE TIME SYNCHRONIZATION FOR MOBILE POSITIONING IN A CELLULAR COMMUNICATIONS SYSTEM

摘要

Multiple radio base stations (RBS1-4) of the method and system for time synchronization are disclosed in cellular communications networks. Reference terminal (106) (for example, modification standard mobile terminal) is placed in the network of each RBS websites of known position, be preferably close to the antenna (104) of base station as close possible to. Reference terminal (106) includes absolute reference function, for synchronizing RBSs (102) relative to public absolute time reference. Therefore, location algorithm can be used for determining the position of mobile terminal (12) in a network with relatively high accuracy.
