- a first step Sl traffic information TI is received.
- control data CD is extracted from the traffic information TI and forwarded to a comparator, for example the comparator 6 from FIG.
- the comparator 6 compares a service identifier SID, a country code CC and a selection number LTN contained in the control data CD with corresponding entries of a predetermined list. If the received combination of service identifier SID, country code CC and selection number LTN is included in the predetermined list, the process branches to a step S4.
- step S4 a flag is set which stores the match found in step S3 for later use. Further, in a step S5, the received value for the selection number LTN is adopted as the value for the white ⁇ tere LTNBE selection number and the value for the selection number LTN set to 0. In the embodiment of Fi gur ⁇ 1, this change of the control data CD by the ERS te manipulation unit 7 is performed. The method is then continued with a step S6. If no match of the received parameters with the stored ones was found in step S3, the method becomes Omission of steps S4 and S5 also proceeded to step S6.
- step S8 in which the state of the possibly set in step S4 flag is queried. If the flag is set, the process branches to a step S9 in which the decryption parameters EP are set to a predetermined value indicating a special mode. Thereafter, the method branches to a step SlO in which the encrypted location identifier cLC is converted into an unencrypted location identifier LC using the decryption parameters EP. In the exemplary embodiment of FIG. 1, this decryption is performed by the decryption unit 5.
- the Entschlüs ⁇ selungsaku 5 is arranged such that, when a decision ⁇ encryption parameter EP that corresponds to the predetermined value for the special mode, does not carry out decoding, and thus the location identifier outputted from the decoding unit 5 with the decryption unit is identical 5 supplied location identifier.
- This special mode is provided as standard for the RDS-TMC traffic information system under the ISO 14819-6 specification for testing purposes. After a decryption or a supposed decryption of the received location identifier by the decryption unit 5, the method is continued with the step Sil.
- one of the ta ⁇ bellarian maps 13 is selected based on the control data, with the help of which the decrypted location identifier LC is converted into a location in plain text, so that a traffic message can be composed and output.
- a conversion and transfer of the traffic report to a navigation system can take place in a designated data format.
- the step Sil is performed by the output unit 11 together with the memory 12 and the tabular maps 13 contained therein.
- the inventive method is for traffic information such service providers that are stored in the predetermined list of the comparator 6, ensures that the to ⁇ gear control, which do not accessible according to the standardized execution of an RDS-TMC-capable mobile terminal for unencrypted location identifiers transmitted is, is made accessible.
- the associated with the activation of the access control device activating the decryption unit is not prevented, but remains because of the use of the test to ⁇ purposes provided special mode without affecting the transmitted location identifier.
- the second manipulation unit 10 can be dispensed with.
- the manufacturer with unencrypted location codes of a proprietary tabular map 13 would have to be subjected to encryption prior to their use in the mobile terminal, for example made by the manufacturer of the mobile terminal responsible for providing the tabular maps in the mobile terminal.
- the same decryption parameters that were used to modify the tabular map would have to be stored in the assigned access profile.
- the solution presented has the advantage that mobile terminal according to the invention is based on a variety known per be ⁇ and proven components.
- the operation of these individual components for example, the Ausenseein- unit 8, the access control device 9 and the decryption unit 5, is unchanged, the interaction of these components is, however, changed by the added components comparator 6, first manipulation unit 7 and second Mani ⁇ pulationshim 10 such that an activation of the access control device 9 is also possible for unencrypted ü transferred location identifiers.
- the service provider responsible for providing the tabular maps 13 of the mobile terminal for example the manufacturer of the mobile terminal, can uniformly provide tabular maps 13 for all mobile terminals and customers, irrespective of the specific, terminal-related usage authorization of these maps.
- a usage control is possible in a uniform manner, ie, as with such service providers, who transmit their traffic information with encrypted location identifiers on the basis of the access profiles.
