Abstract: A method and apparatus of acquiring information on a primary radio access technology (RAT) system in a wireless communication system is provided. An entity of a secondary RAT system transmits a request for information on the primary RAT system to a multi-RAT device, and upon transmitting the request, starting a waiting timer which has a default value. If it is determined that the information on the primary RAT system cannot be acquired, by the multi-RAT device, until the waiting timer expires, the entity of the secondary RAT system reconfigures the waiting timer by a fixed value or a dynamic value.
