Abstract: A method for reacquiring a cell after tune-away for an MSMS mobile communication device includes: measuring pilot signal energy of a cell on which a data call was suspended on a first subscription before tune-away; determining whether the measured pilot signal energy is less than a high threshold RSSI value; determining whether a difference between a measured cell timing and a pre-tune-away cell timing is less than a first threshold timing value; determining whether a strongest pilot signal energy received on one of a plurality of rake fingers is greater than a low threshold RSSI value; decreasing the low threshold RSSI value for reacquiring the cell; and in response to determining that the measured RSSI for the strongest pilot signal energy received on one of the plurality of the receiver rake fingers is not less than the decreased minimum threshold RSSI value, reacquiring the cell and resuming the data call.
