Abstract

A method for requesting and for processing traffic information, in which a traffic-information query is transmitted by a mobile transceiver, and at least one traffic message is provided by a service provider via a base station, the traffic message being transmitted as a brief coded message. Information about the version of the stored data or data groups in the memory allocated to the mobile transceiver, and/or the manufacturer of the stored data or data groups and/or the issue date of the stored data or data groups is transmitted to the base station in the traffic-information query, so that in the return message of the traffic information, the base station can undertake the coding in such a way that the coded data can be well utilized on the basis of the stored data in the vehicle. In this manner, even given changing data, it is ensured in all events that the mobile transceiver is able to interpret the coded traffic messages.

providing at least one traffic message by a service provider via a base station and transmitting the at least one traffic message to the transceiver, the at least one traffic message being transmitted as a TMC message via radio, the at least one traffic message being evaluable on the basis of the at least one group of data stored in the memory.

6. A method for requesting and for processing traffic information, comprising the steps of:

transmitting a traffic-information query by a transceiver, the query including information about at least one of;

(a) a version of at least one group of data, which includes a plurality of data groups for different geographical data, stored in a memory allocated to the transceiver, (b) a manufacturer of the stored data, and (c) an issue date of the stored data; and

providing at least one traffic message by a service provider via a base station and transmitting the at least one traffic message to the transceiver, the at least one traffic message being transmitted as at least one return short message, the at least one traffic message being evaluable on the basis of the at least one group of data stored in the memory.

7. A method for requesting and for processing traffic information, comprising the steps of:

transmitting a traffic-information query by a transceiver, the query including information about at least one of;

(a) a version of at least one group of data, which includes a plurality of data groups of different particularization stored in the memory for a geographical region, stored in a memory allocated to the transceiver, (b) a manufacturer of the stored data, and (c) an issue date of the stored data; and

providing at least one traffic message by a service provider via a base station and transmitting the at least one traffic message to the transceiver, the at least one traffic message being transmitted as at least one return short message, the at least one traffic message being evaluable on the basis of the at least one group of data stored in the memory.

8. A method for requesting and for processing traffic information, comprising the steps of:

transmitting a traffic-information query by a transceiver, the query including information about at least one of;

(a) a version of at least one group of data stored in a memory allocated to the transceiver, (b) a manufacturer of the stored data, and (c) an issue date of the stored data; and

providing at least one traffic message by a service provider via a base station and transmitting the at least one traffic message to the transceiver, the at least one traffic message being transmitted as at least one return short message, the at least one traffic message being evaluable on the basis of the at least one group of data stored in the memory;

wherein the at least one of the version, the manufacturer and the issue date is transmitted in the query separately for each of the at least one data group.

9. A method for requesting and for processing traffic information, comprising the steps of:

transmitting a traffic-information query by a transceiver, the query including information about at least one of;

(a) a version of at least one group of data stored in a memory allocated to the transceiver, (b) a manufacturer of the stored data, and (c) an issue date of the stored data; and

providing at least one traffic message by a service provider via a base station and transmitting the at least one traffic message to the transceiver, the at least one traffic message being transmitted as at least one return short message, the at least one traffic message being evaluable on the basis of the at least one group of data stored in the memory;

wherein the query includes an item of information as to whether a radio receiver having a navigation device evaluates traffic messages only on the basis of one data group, and wherein, in accordance with the item of information, only traffic messages are transmitted which are evaluable with one data group.

10. A method for requesting and for processing traffic information, comprising the steps of:

transmitting a traffic-information query by a transceiver in response to prompting, the query including information about at least one of;

(a) a version of at least one group of data stored in a memory allocated to the transceiver, (b) a manufacturer of the stored data, and (c) an issue date of the stored data; and

providing at least one traffic message by a service provider via a base station and transmitting the at least one traffic message to the transceiver, the at least one traffic message being transmitted as at least one return short message, the at least one traffic message being evaluable on the basis of the at least one group of data stored in the memory.
