Abstract
Abstract Consisting of a cellular mobile communications network (CS) that provides coverage of voice and/or data communications services to terminals located in a set of cells in any one of which there can be at least one fixed cellular terminal (4) that communicates, on one side, by radio, with one of the base stations (3) of the cellular mobile communications network (CS) and on the other side, by cable, with at least one base station (6) of a cordless communications system (WS) through control and interface means that perform the adaptation between the two systems to provide communications services to a number of cordless terminals (7). When the cellular communication system (CS) makes use of time division multiple access technology, TDMA, for example GSM, one single radio transceiver is connected to a transceiver control means to manage the radio channel allocations, so that it can support simultaneously as many communications channels as possible without there being temporal overlapping of channels.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
FIXED CELLULAR COMMUNICATIONS SYSTEM composed by a first cellular mobile communications network (CS) that provides communications coverage for voice and/or data services, in which in any of the cells there is at least one fixed cellular terminal (4) that communicates by radio with one of the base stations (3) and characterised in that the fixed cellular terminal (4) is joined to at least one base station equipment (6) of a cordless communications system (WS), through control and interface means (9) that perform the adaptation of information and control channels between the two systems, in order to provide communications services to a number of cordless terminals (7).
Claim 2
Dependent Claim
93 words
COMMUNICATIONS SYSTEM according to claim 1 characterised in that the fixed cellular terminal (4) that communicates with at least one base station (3) of the cellular mobile communications network (CS) comprises at least one cellular transceiver obtained from a cellular mobile terminal, at least one base station transceiver of a cordless communications system (WS) and control and interface means (9) that incorporate the functions for adapting the two transceivers of the cellular and cordless systems, and for concentrating, when this is necessary, the number of channels offered to the number of channels available.
Claim 3
Dependent Claim
44 words
COMMUNICATIONS SYSTEM according to claim 1 characterised in that the control and interface means (9) that perform the adaptation of the two systems, cellular and cordless, also permit the connection of standard terminals (5) through telephone lines or by means of radiolink equipments (8).
Claim 4
Dependent Claim
35 words
COMMUNICATIONS SYSTEM according to claims 1 and 2 characterised in that both the cellular mobile communications network (CS) and the cordless communications system (WS) can be of either the analogue or of the digital type.
Claim 5
Dependent Claim
58 words
COMMUNICATIONS SYSTEM according to claim 1 characterised in that the control and interface means (9) also permit the setting up of internal communications between cordless terminals (7) without making use of the communications channels of the cellular network, and the centralising of the communications channels offered to both the cordless terminals (7) and to the fixed terminals (5).
Claim 6
Dependent Claim
108 words
FIXED CELLULAR TERMINAL for use in above cellular mobile networks (CS) that communicates with at least one of its base stations (3) in order to provide voice and/or data communications to one or more subscribers characterised in that it comprises a single cellular radio transceiver (RTX) of time division multiple access, TDMA, technology, and transceiver control means (19) connected to this cellular transceiver (RTX) to manage the radio channels, so that they can support simultaneously as many communications channels as possible without there being temporal overlapping of channels, so that it is possible to offer the same number of subscriber lines through the corresponding subscriber line interfaces (SL).
Claim 7
Dependent Claim
36 words
FIXED CELLULAR TERMINAL according to claim 6, characterised in that it also comprises control and interface means (9) that extend the number of channels available through the cellular transceiver into a greater number of subscriber lines.
Claim 8
Dependent Claim
46 words
FIXED CELLULAR TERMINAL according to claim 6 characterised in that instead of a single cellular radio transceiver (RTX), it comprises a number of these connected, on the radiofrequency side, to a single antenna system (ANT) in order to make available a greater number of communications channels.
Claim 9
Dependent Claim
47 words
FIXED CELLULAR TERMINAL according to claim 8, characterised in that it also communicates with a second communications network with cellular access or with another communications network of different types through point to point or point to multipoint radiolinks in order to provide another number of alternative channels.
