<p>A method of controlling a random access mode In a cell (10) of a cellular communication system, said cell (10) being operable in a first random access mode associated with a first set of random access identification sequences or in a second random access mode associated with a second set of random access identification sequences/ said random access identification sequences to be used by terminals (UEl... UEn) performing a random access operation in said cell (10), where said second set of random access identification sequences is arranged for avoiding misidentif ications due to sequence alterations occurring in transmissions from said terminals (UEl... UEn), the method comprising: performing a sequence alteration analysis based on the an output of a random access identification sequence detector (910) in a network entity, and if a mode switching condition is determined on the basis of the sequence alteration analysis, automatically switching operation of said cell (10) from one of said random access modes to the other of said random access modes.</p> |
