Abstract
The present invention relates to digital time division multiple access (TDMA) radio systems employing timing advance. An extended cell system comprises an inner cell (C3) employing a standard timing of transmission and reception, an outer cell (C2) in which the relative timing of reception and transmission is offset with respect to the standard timing. Both the outer cell and the inner cell have an individual broadcasting frequency. The problem is that the mobile station may lock into the outer cell or into the inner cell with the same probability regardless of its actual location area. The mobile station cannot, however, communicate in the wrong cell, but it only causes interference to the other users in the wrong cell. For minimizing these interferences, the time-slot immediately preceding or following the time-slot allocated for transmitting random access bursts on the broadcasting frequency of the outer cell has the lowest priority in allocating the calls in the outer cell or the inner cell, respectively.
