Abstract: A method for performing a cell search in a multi-subscription device is provided. The method includes estimating, by a first subscriber identity module (SIM) of multiple SIMs of the multi-subscription device, search time information required for identifying one cell and margin time information for cell search, where the first SIM is associated with a first radio access technology (RAT); obtaining a discontinuous reception (DRX) period of a second SIM associated with a second RAT in the multi-subscription device; determining a number of cells to be searched during the DRX period based on the estimated information; performing a measurement for one or more cells to be searched based on the number of the cells; ranking the one or more cells based on the measurement; and initiating a cell search on one or more cells having a highest signal strength during the DRX period.
