"Processes to facilitate the timing for a plurality of base stations in a mobile communications system assu00ecncrono,To estimate a timing for a plurality of base stations in a mobile communications system assu00ecncrono and to facilitate the timing between mobile stations and base stations in aA mobile telecommunications network assu00ecncrona, and.Systems for synchronizing a plurality of base stations in a mobile communications system and mobile telecommunications assu00ecncrono "a process and system are provided for facilitating the temporizAction (for example, the differences of timing on known) base station (BSS) (BS1, BS2 and Bs3) in asynchronous CDMA mobile communications systems (200).A plurality of mobile stations (MSS) (MS1, MS2 and MS3) measures the time differences of relation between several pairs of BSS, and these measurements are stored in the BSS.A BS source send (106) to an MS, a message list of neighbors, the estimations of relative time difference between the BS source and each of the BSS in the list of neighboring cell.Each BS on the list may maintain a table of estimation of time difference on, which can be updated continuously from reports received from the MSS.Subsequ00b3entemente, the BSS can submit entries in this table for the MS in the message list of neighbors. Using this new technique, the BSS has the differences of timing on known.As a result, when the MS initiates a search for a candidate cell for BS, the MS already has a pet of the timing of BS when compared with its source BS.As such, the search process of the resulting cell has a level of complexity is lower and thus can be performed much more quickly than with the previously existing procedures.In addition, the estimates of relative time difference may be compared with corresponding time differences that are measured by a second mobile station.Based on this comparison, the propagation delays of signals between the second MS and several BSS can be calculated to determine the position of the second MS.
