International ClassH04B 007/26Foreign Application Priority Data1993-10-08 GBAbstractA 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.Field of SearchHandoffSwitching unit detail (e.g., mobile telephone switching office (MTSO), base station controller (BSC), etc.) Base station selection Mobile assisted or initiated Serving site initiated Handoff initiated by another source (e.g., target, user initiated, mobile switching center (MSC), or mobile telephone switching office (MTSO), etc.) | |
