Cordless telecommunication system with backup interoperability of cordless telecommunication applications, in particular of a gap-specific dect system

A cordless telecommunications system with assured interoperability of cordless telecommunications applications, in particular a GAP-specific DECT system,

• (a) having a cordless base station (G-BS) and a first number “m” of cordless mobile parts (D-MT, G-MT, D/G-MT) which are capable of telecommunication with the cordless base station (G-BS) and the number of which exceeds a second number “k” of telecommunications channels (m>k) which are available in parallel at the cordless base station (G-BS),
• (b) having a third number “m1” of first cordless mobile parts (D-MT) which respond and react to connectionless call messages,
• (c) having a fourth number “m2” of second cordless mobile parts (G-MT) which respond and react to connection-based call messages,
• (d) having a fifth number “m3” of third cordless mobile parts (D/G-MT) which respond and react both to connection-based call messages and to connectionless call messages,
• (e) the cordless base station (G-BS) having first means (MIC, PGMme) for controlling connections for the cordless mobile parts (D-MT, G-MT, D/G-MT), which send a number “j” of connection-based call messages and a number “i” of connectionless call messages, and
• (f) the following conditions applying,
• (1) m=m1+m2+m3, in which case m1,m3 ε N0 where n=0,1,2, . . . and m,m2 ε N1 where n=1,2,3, . . .
• (2) m2≦k-1, in which case k ε N2 where n=2,3, . . .
• (3) j≦k-1, in which case k ε N2 where n=2,3, . . .
