Abstract
A method for selecting an out of service (OOS) scan mode for a wireless communication device is provided. The method can include the wireless communication device detecting occurrence of an OOS condition; setting a displacement threshold in response to the OOS condition; determining a displacement magnitude indicative of a distance traveled by the wireless communication device during the OOS condition; determining whether the displacement magnitude exceeds the displacement threshold; using a first scan mode to scan for network coverage in an instance in which it is determined that the displacement magnitude exceeds the displacement threshold; and using a second scan mode to scan for network coverage in an instance in which it is determined that the displacement magnitude does not exceed the displacement threshold. The first scan mode can have a greater scan frequency than the second scan mode.
