Abstract
A cellular mobile telephone system is provided. The system operates on frequency bands each of which comprises a respective total number of sub-bands. Each sub-band has a different respective frequency. The system includes a network of base stations, and mobile stations. The mobile stations comprise a given mobile station communicating with the network on a sub-band within a current operational frequency band comprising one of the operational frequency bands. The network transmits to the given mobile station certain information regarding designated sub-bands for which the given mobile station is to perform measurements. The certain information comprises a minimum number of alternate sub-bands of an alternate operational frequency band other than the current operational frequency band. The given mobile station receives from the network the certain information and transmits to the network a measurement report comprising measurement results for a number of alternate sub-bands equal to at least the minimum number but less than the total number of alternate sub-bands.
