1. A method of sending a user message through a transmission network (3), the method being characterized in that:
- a request is activated to set up a call channel between a caller and a called party;
to set up the call channel, a signaling stage is performed during which a signaling message containing at least one spare field is interchanged between the caller and the called party;
and in that;
before the interchange between the called party and the caller, the user message is placed in the spare field of the signaling message; and
the setting up of the call channel is terminated once the user message has been received by the called party and/or a reply to the receiver message has been received by the caller.

Abstract
To reduce the call cost for user messages of a few tens of bytes through a mobile telephone network (3), and to avoid having to set up a call channel as is necessary for transmitting data of several thousands of bytes, spare fields in signaling messages are used to convey the user messages, a call then taking place via signaling messages, and without a dedicated call channel being set up.

- 8. A transceiver device (1) for transmitting a user message to a called party and for receiving a reply to the user message from a called party, said device being characterized in that it includes a dedicated memory (22), the dedicated memory serving to store the user message and/or the reply to the user message, the user message and/or the reply being sent in a spare field of a signaling message during a signaling stage.
