Abstract:
1. A method for transmitting a message from a first to a second telecommunication terminal, of which at least one of the first and the second telecommunication terminal is connected to a line-connected telephone network with DTMF signaling, the method comprising the steps of: mapping onto the line-connected network and expanding at least one of an SMS protocol architecture of a GSM standard and a comparable architecture of a UMTS standard; inputting the message as a short message, via one of an input keypad and a touchscreen, on the first telecommunication terminal; converting the short message into a short message format; establishing a logical connection setup via an adequately specified data link layer, combined with a short message transfer layer, a short message relay layer, and a connection management layer; transmitting the short message in the short message format in an adequately specified physical layer via one of DTMF and FSK off-hook signaling to a short message service center and from the short message service center to the second telecommunication terminal; converting, in the second telecommunication terminal, the short message obtained from the short message service center, into an output format; and outputting the short message in the output format on a display unit.
