METHOD AND APPARATUS FOR ACQUIRING INFORMATION USING DEVICE IN IDLE STATE IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method of acquiring, by an entity of a secondary radio access technology (RAT) system, information on a primary RAT system in a wireless communication system, the method comprising:
- transmitting a request for information on a primary RAT system to a multi-RAT device supporting a plurality of RATs;
upon transmitting the request, starting a waiting timer which has a default value;
receiving a response of the request, which includes a rejection for the request and a reason for the rejection, from the multi-RAT device, 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;
reconfiguring the waiting timer based on the response; and
receiving a second response of the request, which includes an approval for the request and the information on the primary RAT system, from the multi-RAT device, before the reconfigured waiting timer expires.

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.

9. A method of transmitting, by a multi radio access technology (RAT) device supporting a plurality of RATs, information on a primary RAT system in a wireless communication system, the method comprising:
-
receiving a request for information on a primary RAT system from an entity of a secondary RAT system; upon receiving the request, starting a waiting timer which has a default value; determining whether or not the information on the primary RAT system can be acquired from a base station of the primary RAT system until the waiting timer expires; if it is determined that the information on the primary RAT system cannot be acquired until the waiting timer expires, transmitting a response of the request, which includes a rejection for the request and a reason for the rejection, to the entity of the secondary RAT system. - View Dependent Claims (10, 11)
