Abstract

A method 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.

Claims

1. A method for transmission of a message from a first telecommunication terminal to a second telecommunication terminal, of which at least one terminal is connected to a line-connected telephone network, comprising:

inputting a short message, via an input keypad or a touchscreen, to the first telecommunication terminal;

converting the short message into a short message format;

establishing a connection setup to the network;

transmitting the short message in the short message format to a short message service center and further to the second telecommunication terminal, wherein the transmission of the short message in the short message format to the short message service center and/or to the second telecommunication terminal is carried out by means of DTMF or FSK off-hook signaling in the voice band, and

converting the short message obtained from the short message service center in the second telecommunication terminal into an output format.

2. A telecommunication system for transmission of a message from a first telecommunication terminal to a second telecommunication terminal, comprising:

a short message service center assigned to a line-connected telephone network, wherein at least one of the first telecommunication terminal and the second telecommunication terminal is connected to the line-connected telephone network;

a first and second input keypad or a touchscreen, operatively coupled to the first and second terminals respectively for inputting the message in a short message format;

means for converting the short message into a short message format;

means for establishing a connection setup;

means for transmitting the short message in the short message format to the short message service center and further to the second telecommunication terminal;

wherein the transmission of the short message in the short message format to the short message service center and/or to the second telecommunication terminal is carried out by means of DTMF or FSK off-hook signaling in the voice band, and wherein

the short message obtained from the short message service center is converted in the second telecommunication terminal into an output format.

3. The telecommunication system as claimed in claim 2, wherein one of the telecommunication terminals is connected to a mobile radio network, and the line-connected network being connected to the mobile radio network via a gateway mobile switching center.

4. The telecommunication system as claimed in claim 2, wherein one of the telecommunication terminals is a cordless telephone which is connected to the line-connected telephone network via a fixed station or private branch exchange.

5. The telecommunication system as claimed in claim 2, wherein a transmission protocol in which a short message transfer layer in accordance with ETSI GSM03.40 and a connection management layer according to GSM04.11 are defined in addition to a data link layer and a physical layer.

6. The telecommunication system as claimed in claim 5, wherein a short message relay layer according to GSM03.40 and 04.11 is defined in the transmission protocol.

7. The telecommunication system as claimed in claim 5, wherein an additional message for the specific signaling of the connection state to the calling unit in the format according to GSM04.07/chapter 11 is defined in the connection management layer.

8. The telecommunication system as claimed in claim 5, wherein the format of a message in the data link layer (DL) comprises

a field “

mark signal”

,

a field “

message type”

,

a field “

message length”

,

a field “

CM layer message CP_ . . . ”

,

a field “

checksum”

,

the fields in the format being arranged in the above order.

9. The telecommunication system as claimed in claim 2, wherein the short message service center is assigned to the line-connected telephone network and serves for the transmission of short messages in the short message format.
