Abstract
Abstract A radio telephone capable of being operated in more than one radio telephone system, comprising communication means respectively associated with each of the more than one radio telephone system, monitoring means for monitoring signals of the more than one radio telephone system, and selection means responsive to said monitoring means for automatically selecting and re-selecting respective said communication means in accordance with the signals of one of the more than one radio telephone system fulfilling at least one predetermined criterion. The predetermined criterion can be based on a number of features such as received signal strength, access rights, system requests, least BER or frame error rate and user velocity. The radio telephone can be used in a radio telephone system adapted to co-operate with at least one other radio telephone system, comprising user information exchange means respectively associated with each of the at least one other radio telephone system for exchanging user information signals between the radio telephone system and the at least one other radio telephone system, monitoring means for monitoring user information signals of the radio telephone systems and selection means for automatically assigning and re-assigning a user to one of the radio telephone systems in accordance with the user control signals fulfilling at least one predetermined criterion.
