Abstract
A method of controlling a mobile terminal allows it to search for possibly higher priority service providers in response to receiving an indication that more than the default number of service providers is available in a given service area, without dropping its current radio channel. When only the standard number of service providers is available in a given area, the mobile terminal uses standard frequency bands and corresponding radio channel allocations during scanning operations. When more than the standard number of service providers is available, the mobile terminal uses received information defining the non-standard spectrum allocation supporting the available service providers in its scanning operations. In a wireless communication system operating in accordance with TIA/EIA-136 standards, the mobile terminal may scan its current hyperband, alternate hyperband, or both the current and the alternate hyperbands (e.g., 800 MHz and 1900 MHz hyperbands), for higher priority service providers.
