Random access mode control method and entity

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