Abstract
Abstract The signalization device is permanently installed in a peripheral (4, 9) of the communications network, or provided by a chip card inserted in the latter, with a central control (8) controlling the forwarding of the signalization within the communication network. The signalization is provided by a data communication via which data telegrams are exchanged between at least 2 coupled subscribers, provided as a standardised data set, with an additional identification code, for indicating the authorised services, the identification code is verified by a software filter (12.1, 12.2), associated with the subscriber and with a service centre (10). <IMAGE>

Claim 1
Independent Claim
295 words
Device for transmitting messages in a communication network for voice and data processing having a plurality of terminals (4, 9) which are allocated to a specific user or can be allocated to a specific user by means of a data carrier (22) insertable in the terminal, at least two terminals (4, 9) being capable of entering into voice or data communication with one another, and having at least one centre (8) for controlling the message transmission within the communication network, each message transmission being a data communication wherein data telegrams (35, 39) are exchanged, containing a standardized data header (36, 37) for establishing the identity of the subscriber and the authenticity of the message, and having at least one central unit (10) present in the communication network, at least some of the terminals (4, 9) and the central unit (10) having means for generating the data header (36, 37) of the data telegrams (35, 39), the data telegrams being transmitted either from the central unit (10) to at least one of the terminals (4, 9) or from one of the terminals to the central unit (10), there being facilities for checking the data header (36, 37) in the central unit (10) and in said at least some of the terminals /(4, 9), characterized in that the data telegrams contain an identification code (40) definable by the respective network provider, that the central unit (10) and said at least some of the terminals (4, 9) have means for generating the identification code (40) and filters (12.1, 12.2) for recognizing the identification code (40), the identification code (40) being a security facility definable by the respective network provider for the transmission of certain messages and being contained in the data telegram immediately following the standardized data header.
Claim 2
Dependent Claim
33 words
Device according to claim 1, characterized in that the communication network is a digitally operating communication network, particularly a cellular mobile radio telephone network (1) according to the GSM or DCS 1800 standard.
Claim 3
Dependent Claim
43 words
Device according to claim 1 or 2, characterized in that each of the filters (12.1, 12.2) associated with the terminals (4, 9) has a software module contained in a storage means (26) in the terminal (4, 9) or on the data carrier (22).
Claim 4
Dependent Claim
48 words
Device according to one of the claims 1 to 3, characterized in that at least some of the terminals are mobile radio telephones (4), each comprising a device (21) for exchanging data with the data carrier, particularly with a chip card (22) insertable in the mobile radio telephone.
Claim 5
Dependent Claim
66 words
Device according to one of the claims 1 to 4, characterized in that data telegrams (39) containing the identification code (40) are merely part of a message comprising a plurality of data telegrams (39), the number of data telegrams for the complete message and information for the position of a respective data telegram within the message being contained in each data telegram in the identification code.
Claim 6
Dependent Claim
59 words
Device according to claim 5, characterized in that there is a checking means (32) which works in such a way that each data telegram belonging to a message is stored in the storage means (25, 26), and that the further processing of the data telegrams does not take place until the complete message is present in the storage means.
Claim 7
Dependent Claim
56 words
Device according to one of the claims 1 to 6, characterized in that modules (14, 15) for managing authorization data of individual subscribers authorized to transmit messages (39) having the identification code (40) and for calculating, encoding, and checking a security code (43) contained in the identification code (40) are associated with the central unit (10).
Claim 8
Dependent Claim
41 words
Device according to claim 7, characterized in that the value of a random number (RAND) is included in the security code (43), the random number itself being preferably a function of the message defined by the provider of the communication network.
Claim 9
Dependent Claim
33 words
Device according to one of the claims 1 to 8, characterized in that the data telegrams provided with the identification code (40) are components of special services offered by the communication network provider.
Claim 10
Dependent Claim
31 words
Device according to one of the claims 1 to 9, characterized in that the data telegrams (39) provided with the identification code (40) contain the message information (44) in encoded form.
