Abstract
A method and intelligent roaming mobile station for emulating a pre-intelligent roaming scanning routine used by a pre-intelligent roaming mobile station. The method includes the steps of selecting a search scheme from a plurality of search scheme, and restricting an intelligent roaming scanning routine to scan only the service bands within an 800 MHZ spectrum. In response to the selected search scheme, the intelligent roaming mobile station then prioritizes at least one service band operating in the 800 MHZ spectrum into a band scan order. Thereafter, the intelligent roaming mobile station scans for a channel according to the prioritized band scan order, where the channel connects a service provider to the intelligent roaming mobile station according to the selected search scheme.
