First Claim
Patent Images
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.

2. A telecommunication system for transmitting a message from a first to a second telecommunication terminal, comprising:
-
a first and a second telecommunication terminal; a line-connected telephone network with DTMF signaling, wherein at least one of the first and the second telecommunication terminals is connected to the line-connected telephone network; and an SMS transmission protocol in which a data link layer is specifically defined and combined with a short message transfer layer, a short message relay layer and a connection management layer, and in which a physical layer is specifically defined; wherein at least one of the SMS protocol architecture of a GSM standard and a comparable architecture of UMTS standard is mapped onto the line-connected telephone network and expanded, the message is input as a short message via one of an input keypad and a touch screen on the first telecommunication terminal, the short message is converted into a short message format, a logical connection set-up is established via the data link layer combined with the short message transfer layer, the short message relay layer and the connection management layer, the short message is transmitted in the short message format in the 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, and the short message obtained from the short message service center is converted, in the second telecommunication terminal, into an output format and is output on a display unit. - View Dependent Claims (3, 4, 5, 6, 7)
