The present invention discloses a method and User Equipment (UE) for acquiring random access information. The method comprises: during a random access procedure, the UE measures and acquires parameter information in the random access procedure; and after the success of the random access, the UE reports partial or all of acquired parameter information to a base station. According to the present invention, the base station can optimize the random access according to the parameter information reported by the terminal, thereby improving the precision of the random access optimization.
