Method for preparing an interfrequency handover, a network element and a mobile station

A method for preparing part corresponding connection of the first frequency method of the second rendering frequencies switch (600), a steps: The circulation interrupts (603) is/receiving of multiple gaps a first frequency the emitting of data transmission, the notch is in each transmitting cycle is at least part and sending cycle sequence (420,520) by, and method for (607) measurement a second frequency of the emitting end of the first frequency. The method to the surface of the transmission of interrupter data sending/receiving of the rotor protruded step: Ends are all a gap of the first duration (311,412) and at least one cycle sending, a a second transmission end of the second duration (312,411) interrupts the transmission for (604,606) data/receiving, the second duration is different from the first duration. Also provides a mobile station (700) and a network element (710) and network control unit (720).
