摘要
Methods and systems are provided for using base-station location to assist mobile- device system acquisition. A mobile station, which stores a network identifier, selects a carrier frequency. The mobile station receives, from a base station on a first carrier frequency, geographic coordinates of the base station and a base-station network identifier, and determines whether the base-station network identifier matches the mobile-station network identifier. If the base-station network identifier matches the mobile-station network identifier, the mobile station will scan the indicated home frequency bands and will connect to one of the home frequencies, and if the base-station network identifier does not match the mobile-station network identifier, the geographic coordinates of the base station are used to identify a market area and a most-preferred carrier frequency is selected from the identified market area.
