 A dual mode terminal is provided, in which a mobile station of a mobile radio system and cordless telephone are combined. This kind of terminal can have a connection with both a base station of the mobile radio system and a base station (fixed part) of the cordless telephone system. Handover in the case of this dual mode terminal implies the transfer of a call from the base station of the mobile radio system to a base station of the cordless telephone system. A call re-establishment procedure is utilized for inter-system handovers between a cordless telephone system having terminal-initiated handovers and the supporting mobile radio system having network-initiated handovers. A single mode (cordless) terminal and a method of performing handover from a base station of the cordless telephone system to another base station of the cordless telephone system is also provided.
