发明名称 CORDLESS TELECOMMUNICATION SYSTEM WITH ASSURED INTEROPERABILITY OF CORDLESS TELECOMMUNICATIONS APPLICATIONS, IN PARTICULAR A GAP-SPECIFIC DECT SYSTEM
摘要 The invention pertains to a cordless telecommunication system with backup interoperability of cordless telecommunications applications, in particular a GAP-specific DECT system (DECT/GAP system) with a cordless base station (G-BS) and cordless mobile units (D-MT, G-MT, D/G-MT) capable of telecommunication with the cordless base station (G-BS) via an air interface and greater in number than the telecommunication channels available in parallel with the cordless base station. To ensure that a multiaddress/group call is possible and interoperability of the cordless telecommunication applications is preserved, use is made of a hybrid mode based on a connection-based quasimultiaddress/group call and a connectionless multiaddress/group call. The cordless base station (G-BS) is configured to show to which cordless mobile unit (D-MT, G-MT, D/G-MT) a connection-based quasi-multiaddress/group call (GAP call; connection-based call) goes and to which cordless mobile unit (DMT, G-MT, D/G-MT) a connectionless multiaddress/group call goes. The cordless base station (G-BS) is provided with appropriate means (MIC, PGMme) for controlling the connections to the cordless mobile units.
