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.

Abstract: A method is proposed for analyzing digital signals which are transmitted on a transmission frequency other than one set on a radio receiver. For this purpose, within a read cycle of thereceiver section of a radio receiver, a short-term and temporary switchover is made, during the duration of successive bits of the digital signal, from the current frequency to the other frequency, and the bits of the digital signal received during the temporary switchovers are buffered. The buffered bits of the digital signal are analyzed subsequently to the read cycle, or concurrently therewith.
