Abstract

Abstract In a cordless telecommunications system with assured interoperability of cordless telecommunications applications, in particular a GAP-specific DECT system (DECT/GAP system), having a cordless base station (G-BS) and having cordless mobile parts (D-MT, G-MT, D/G-MT) which are capable of telecommunication with the cordless base station (G-BS) via a radio interface and the number of which exceeds the number of telecommunications channels which are available in parallel at the cordless base station, collective/group calls being possible while the interoperability of the cordless telecommunications applications remains ensured, mixed operation is implemented, comprising a connection-based virtual-collective/group call and a connectionless collective/group call. In this case, [lacuna] is configured in the cordless base station (G-BS), to which cordless mobile part (D-MT, G-MT, D/G-MT) a connection-based virtual-collective/group call (GAP call; connection-based call) goes and to which cordless mobile part (D-MT, G-MT, D/G-MT) a connectionless collective/group call (connectionless call) goes. To this end, the cordless base station (G-BS) has means (MIC, PGM me ) which are designed in an appropriate manner for this purpose, for controlling connections for the cordless mobile parts.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 261 words
1 . 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 “m 1 ” of first cordless mobile parts (D-MT) which respond and react to connectionless call messages, (c) having a fourth number “m 2 ” of second cordless mobile parts (G-MT) which respond and react to connection-based call messages, (d) having a fifth number “m 3 ” 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, PGM me ) 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=m 1 +m 2 +m 3 , in which case m 1 ,m 3 ε N 0 where n=0,1,2, . . . and m,m 2 ε N 1 where n=1,2,3, . . . (2) m 2 ≦k- 1 , in which case k ε N 2 where n=2,3, . . . (3) j≦k- 1 , in which case k ε N 2 where n=2,3, . . .
Claim 2
Dependent Claim 261 words
1 .
