Abstract: The mobile communication device supports a plurality of RATs and includes a first wireless transceiver, a second wireless transceiver, and a controller. The first wireless transceiver performs wireless transmission and reception to and from a first cellular network utilizing a first RAT. The second wireless transceiver obtains a non-cellular signal indicator. The controller determines whether the first RAT is a predetermined one of the plurality of RATs when the mobile communication device camps on the first cellular network, and if not, predicts whether there is a second cellular network available, which utilizes the predetermined RAT, based on the non-cellular signal indicator. In response to predicting that the second cellular network is available based on the non-cellular signal indicator, the controller further enables the mobile communication device to camp on the second cellular network via the first wireless transceiver.
