Abstract: An out-of-service recovery search method includes establishing a frequency list including at least one searchable frequency, searching a suitable cell of a network according to the frequency list when the user terminal is in an out-of-service state, determining at least one first skip condition of the user terminal, performing a full-band power scan mechanism for scanning received signal strength indication (RSSIs) of user terminal supported frequency bands when the at least one first skip condition of the user terminal is absent and no suitable cell of the network is searched within the searchable frequency of the frequency list, skipping the full-band power scan mechanism when the at least one first skip condition of the user terminal is present and no suitable cell of the network is searched within the searchable frequency, and performing an RSSI sniffer for scanning a signal power of each frequency of the searchable frequency.
