METHOD USED BY A MOBILE STATION OF A CELLULAR RADIOCOMMUNICATIONS SYSTEM HAVING SEVERAL CELL TYPES, TO DETERMINE THE TYPE OF THE CELL TO WHICH IT IS LINKED, AND MOBILE STATION ANDBASE STATION USING SAID METHOD

摘要

the present invention relates to a method of determining, in a cellular radio communication system, several types of cells.the type of the cell to which the mobile station is attached, characterized in that it includes the following steps: the network broadcast system.the destination of the mobile station, of a message, said message of recognition, in the form of a sinusoidal frequency as the recognition.the frequency is shifted relative to said reference, known or determinable by the mobile station, the difference may be zero.between the reference frequency and the frequency of recognition is characteristic of the type of the cell, the mobile station of the determined frequency of recognition.determination of the mobile station, the difference between the reference frequency and the frequency of recognition.determination of the mobile station of the type of the cell from the time specified.
