Abstract
A wireless communication device is disclosed for scanning a preferred roaming list (PRL) in a non-roaming mode. The wireless communication device exchanges wireless communications with a first wireless communication network and monitors communication performance of the first wireless communication network while operating in a non-roaming mode. The wireless communication device processes the PRL to perform scans for a pilot signal from a second wireless communication network while operating in the non-roaming mode. The wireless communication device subsequently performs a time correlation of the communication performance of the first wireless communication network and the scans for the pilot signal of the second wireless communication network to determine that a roaming mode should be entered. The roaming mode is then entered and the wireless communication device exchanges wireless communications with the second wireless communication network while operating in the roaming mode.
