Method for transmitting short messages

#The invention is based on a method for transmitting short messages.

#Short message services are already known that serve to send a short message to a subscriber of a telecommunications network without requiring that a telecommunications connection to the subscriber be made beforehand. This is of particular importance in mobile radio systems, since subscribers in such systems are often unreachable. Incoming short messages for the subscriber are stored in memory by a network operator of the telecommunications network and forwarded to the intended subscriber at a later time. The subscriber is informed of the arrival of a short message intended for him so that he can then download the short message from the network operator.

#One example of a short message service using the GSM Standard (Global System for Mobile Communications) is the Short Message Service (SMS). In a short message, up to 160 7-bit ASCII (American Standard Code for Information Interchange) text characters can be transmitted.

#Exemplary embodiments of the invention are shown in the drawing and described in further detail in the ensuing description.

#FIG. 1 shows a first block circuit diagram for transmitting short messages in a telecommunications network;

#FIG. 2 shows a general makeup of a transmission frame;

#In FIG. 1, 60 designates a first subscriber and 65 a second subscriber of a telecommunications network 10, which is embodied in particular as a radiotelecommunications network, for example as a mobile radio network. The first subscriber 60 and the second subscriber 65 are each embodied as a telecommunications device, in particular as a radio unit, for example as a mobile radio device, service radio device, as a radio handset, or the like. In FIG. 1, a network operator 70 of the telecommunications network 10 is also shown; it can also be called a telecommunications device, and in particular a radio unit. The central station can also be assigned to an external service provider that is other than the network operator. However, below for the sake of example it will be assigned to the network operator 70.

#In a first exemplary embodiment in accordance with FIG. 1, in the second subscriber 65, a short message 5 for the first subscriber 60 is prepared and is broadcast, suitably addressed, to the network operator 70 via the telecommunications network 10.

#In a second exemplary embodiment of FIG. 4, the same reference numerals identify identical elements. Unlike the first exemplary embodiment, the second subscriber 65 communicates with the network operator not via the telecommunications network 10 but rather via a data network 80, which by way of example can take the form of the Internet, and a net connection unit 85. The short message prepared in the second subscriber 65 is sent to the network operator 70, with suitable addressing, via the data network 80 and the net connection unit 85, for instance in the form of electronic mail, such as e-mail.
