Abstract: 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.

Abstract: A dual mode terminal is provided, in which a mobile station of a mobile radio system and a cordless telephone are combined. This kind of terminal may have a connection with both a base station of the mobile radio system and a fixed part of the cordless telephone system. Handover may imply the transfer of a call from a fixed part of the cordless telephone system having a terminal-initiated handover to a base station of the mobile radio system having a network-initiated handover. In order to carry out a proper handover procedure, the cordless telephone part obtains from the mobile station part of the terminal measurement results relating to received signal strengths of the mobile system base stations in the neighborhood. The cordless telephone part of the terminal forwards these measurement results via a fixed part of the cordless telephone system to the mobile exchange of the mobile system in a handover request message.
