Method for identifying base stations of a time division cellular network in a mobile station and mobile station
First Claim
1. A method for identifying base stations of a time division cellular network in a mobile station, wherein:
- frame timing difference data for neighbour base stations are transmitted from the serving base station to the mobile station;
characterized in that reception times for the neighbour base stations'"'"' system data are determined in the mobile station on the basis of said frame timing differences; and
system data are read and neighbour base stations are identified.

Abstract
The invention relates to a method for identifying base stations of a time division cellular network in a mobile station. An object of the invention is to speed up the identification of new base stations. In accordance with the invention
frame timing difference data for the neighbor base stations (301) and/or the broadcast control channel time slot data for the neighbor base stations are transmitted from the serving base station to the mobile station;
reception times for the neighbor base stations'"'"' system data are determined in the mobile station on the basis of said frame timing differences and/or the broadcast control channel time slot data (302) and
system data are read and neighbor base stations are identified (303). The invention is also directed to a mobile station applying the method.
