Abstract
A method () in a CDMA terminal device for acquiring a system identified in an enhanced preferred roaming list (enhanced PRL), with at least one entry containing a mobile country code, includes the steps of obtaining () system identifiers from SYNCH channels on a scan list, determining () if the system identifiers match entries on the enhanced PRL, and inserting () channel information items on a first list if the system identifiers do not match entries on the enhanced PRL. If all channels on the scan list have been scanned without any system identifiers matching entries on the enhanced PRL, the method obtains () mobile country codes using channel information items from the first list, determines () if the mobile country codes match entries on the enhanced PRL, and camps () on a system if its mobile country code matches an entry on the enhanced PRL.
