Abstract: A convenient, trouble-proof, economical identification of a place, especially for remote-controlled navigation of a vehicle through a traffic network, is made possible by a terminal unit, a central station and a method for identifying a name via the terminal unit, especially for identifying an interrogated name of a starting location or destination or current location of a route in a navigation terminal unit based on a plurality of characters which are a component of the name and are interrogated in the terminal unit as a character string. It it is determined whether or not the interrogated character string corresponds to the start of a character string contained in a list of exceptions. This latter character string being contained in a plurality of names.

Abstract: The invention relates to a process for data exchange via a communications channel between a central unit, which processes, stores and provides data, and a data terminal device. Initially, a permanently unchanged application-independent query structure (general query structure) is stored both in the central unit and in the data terminal device, as are a small number of permanently unchanged application-independent response formats. For each application, the specific query structure is defined on the basis of the general query structure and is stored in the central unit in the form of a parameter set. As needed, the data terminal device requests from the center unit, via the communications channel, a specific query structure not yet stored in the data terminal device and receives and stores the applicable parameter set.

Abstract: A convenient, trouble-proof, economical identification of a place, especially for remote-controlled navigation of a vehicle through a traffic network, is made possible by a terminal unit, a central bureau and a method for identifying a name by means of a terminal unit, especially for identifying an interrogated name of a starting location or destination or current location of a route in a navigation terminal unit based on a plurality of characters which are a component of the name and are interrogated in the terminal unit as a character string, wherein it is determined whether or not the interrogated character string corresponds to the start of a character string contained in a list of exceptions, this latter character string being contained in a plurality of names, wherein the user is asked to enter additional characters of the name when it is determined that the interrogated character string is contained in the exception list, while a process for unambiguous identification is introduced without further char
