ABSTRACT:
A method of performing an inter-RAT measurement for a handover from NB-TDD to GSM is provided. A UE, as it moves from an NB-TDD Node B to a GSM cell, receives a measurement control message from the NB-TDD Node B. The UE then measures the strength of a signal received from the GSM cell and verifies its identification for a predetermined measuring time. If the UE successfully verifies the identification of the GSM cell for the measuring time, it reports the signal strength measurement and the verified GSM cell identification to the NB-TDD Node B. If the UE fails to verify the identification of the GSM cell for the measuring time, it reports only the signal strength measurement to the NB-TDD Node B.
