Method and telecommunication system for transmission of a message
First Claim
1. A method for transmitting a message between a telecommunication terminal which is coupled with a line-connected telephone network and a short message service center, the method comprising the steps of:
- inputting the message via a keypad or a touch screen of the telecommunication terminal or transmitting the message to the short message center for further distribution to the telecommunication terminal,converting the message into the short message format,establishing via a specified physical layer and a specified data communication layer a link between the telecommunication terminal and the short message service center,transmitting the message in the short message format via a FSK-Off-Hook signaling within the voice band between the telecommunication terminal and the short message center,converting the message in the short message format into an output format which is output in the telecommunication terminal or further distributing the message in the short message format by the short message service center to a further telecommunication terminal.

Abstract
A method, telecommunication terminal, short message service center and telecommunication system is disclosed for transmission of a message from a first telecommunication terminal to a second telecommunication terminal, of which at least one is connected to a line-connected telephone network. The message is converted as a short message into the short message format, a connection setup is realized and the short message is transmitted in the short message format to a short message service center and from the latter to the second telecommunication terminal, where the transmission of the short message to the short message center and/or to the second telecommunication terminal is carried out by means of DTMF or FSK off-hook signaling in the voice band.
