Abstract
A mobile device operates for communications via a first wireless network with use of a first transceiver. The device performs scanning operations with use of a second transceiver for identifying a set of cell IDs corresponding to a plurality of stations of one or more second wireless networks. The device stores the set of cell IDs in association with an ID of the first wireless network. While operating for communications with use of the second transceiver, the device maintains the first transceiver in a low power state. The device performs scanning operations with use of the second transceiver for identifying a current set of cell IDs, and compares the cell IDs of the current set with cell IDs of the stored set. The device maintains the first transceiver in the low power state or enables its operation based on the comparison.
