Definitions

• the present invention relates to a communication system including message means for providing messages in a language according to the preamble of patent claim 1.
• a communication system for example as known from DE 44 30 991, it may be required to provide subscribers with messages related to certain system statuses, or to provide subscribers with messages related to certain system services. These messages are usually transmitted to a calling subscriber, however, may also be transmitted to a called subscriber. Particularly in mobile communications systems covering a plurality of countries, it may occur that messages are provided by units of the communication system, which are located far away from the subscriber, for example in a region or country with a different language. In this case a message may be transmitted in a language which is not understood by the subscriber. For example, a subscriber placing a call to another country and dialing an invalid extension will be provided with a message like "you dialed an invalid extension number" in the language of the respective country.
• a subscriber To avoid communication problems when transmitting messages to a subscriber, it is desirable to be able to provide a subscriber with a message in a language understood by the subscriber. This is particularly desirable in a mobile communication network, for example a communication network according to the GSM-standard.
• DE 44 30 991 describes a communication network allowing to transmit a message to a caller in different languages.
• the network may, in particular, be a mobile communication network, e.g. a GSM-network.
• a notification number is generated, consisting of a fixed portion of digits for determining the type of the message, and consisting of a variable portion of digits for selecting a specific language for the message.
• the digits for selecting the language for the message may be derived from the number dialed by the calling subscriber. In case a particular language is unavailable, a predetermined language may be used as a language for the message instead.
• DE 44 30 991 further describes to assign certain subscriber data to each subscriber, specifying at least one language for a message.
• Data specifying said at least one language are fixedly assigned to the subscriber and are stored in his home location register.
• the home location register centrally stores important subscriber data of a large number of subscribers. If more than one language is stored, a replacement language may be selected, in case a language is unavailable.
• Language selection data is transferred to a temporary register of a respective transmitter station of the communication system which currently serves the subscriber. In case the subscriber moves from one transmission station into the coverage area of a second transmission station, the data is stored in the temporary register of the second transmission station.
• subscribers of a communication network may be provided with messages in a particular language, by specifying a desired language for a message means, e.g. by entering it via a telephone keyboard or by analyzing the telephone number entered by the caller with respect to country codes or sequences of numbers, which specify regions of the country.
• This object of the invention is solved by a communication system having a message device for transmitting messages in one of different languages according to the features of claim 1.
• the system comprises at least one transmission device, at least two communication devices, e.g. telephones, at least one storage device for storing a list assigned to a subscriber containing at least one preferred language, and at least one message device for providing a message in one of different languages. Furthermore, the system comprises at least one subscriber input/retrieval device for inputting, changing or deleting the list of preferred languages.
• the system thus advantageously allows a subscriber to define an assigned list of preferred languages or to change an existing list of preferred languages.
• the subscriber input/retrieval device may comprise input means, for example a keyboard for inputting certain commands or sequences of numbers corresponding to preferred languages. Further, the subscriber input/retrieval device can be used to interrogate and display the list of preferred languages. Furthermore, the subscriber input/retrieval device allows to delete the list of preferred languages. Languages may be entered in a certain sequence in accordance to subscriber preference. During a set-up of a connection in the net, the list with the at least one preferred languages assigned to a subscriber is transmitted. As a consequence, the list is available to the at least one message device.
• selection means may screen the languages in the sequence of preference in order to determine whether at the message device the message is available in the respective language.
• the message may be transmitted to the subscriber in a first available language. If the message is not available in any one of the preferred languages, a known language selection method may be used or the message is transmitted in a predetermined language.
• the message device is usually not directly accessed by the subscriber, it rather is activated by certain processes in the communication system and/or a respective list with at least one preferred language is transmitted to the message device or is actively retrieved by the message device.
• the at least one subscriber input/retrieval device is integrated into a communication means, e.g. into a mobile telephone, such that the subscriber can input or change the list of preferred languages by using said communication means.
• the invention allows a secure transmission of information regarding preferred languages to the message device.
• the transmission of information in the communication network may include ISDN-connections.
• the storage means transmits the list of at least one preferred languages to the message device.
• the message device selects a language in- accordance with the sequence of languages of the list and transmits the message to the subscriber in the selected language.
• the message device can advantageously comprise retrieval means, which actively retrieve the list from storage means, in case the list was not received.
• the retrieval means may send a retrieval command to the storage means, causing a re-transmission of the list from the storage means to the message device.
• the retrieval means may include means for determining whether or not a list of preferred languages is assigned to the respective subscriber.
• a list with at least one preferred language assigned to a calling or called subscriber may be transmitted to the message device and the calling and/or the called subscriber may be provided with a message.
• the communication system may be a mobile telephone network according to the GSM standard and/or may comprise a further mobile communication network and/or a PSTN (Public Switched Telephone) network.
• the communication network includes a communication network according to the GSM standard, the list of preferred languages may be transmitted in an extension part of the MAP (Mobile Application Part) protocol.
