Abstract
A method and apparatus of searching for an operator network in a multi-Radio Access Technology (RAT) environment are provided. The method, calculating a length of a sleep interval to perform background Public Land Mobile Network (PLMN) searching, comparing the length of the sleep interval with a predetermined reference parameter, if the length of the sleep interval is larger than the reference parameter, performing background PLMN searching of a passive RAT during the sleep interval, and if the length of the sleep interval is equal to or smaller than the reference parameter, performing background PLMN searching of an active RAT during the sleep interval.
