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.

Abstract: A communication network system includes a Redcap UE, at least one Redcap base station and at least one regular base station. The Redcap UE currently camping on a Redcap cell covered by a Redcap base station searches for regular neighboring cells covered by a regular base station in the surrounding. The related search information is stored as a database in the Redcap UE, wherein each detected regular neighboring cell is marked as a barred cell and/or the frequency associated with each barred cell is marked as a barred frequency. The Redcap UE performs mobility decisions and interference countermeasures based on the database, thereby improving the success rate and the reliability of handover.
