Abstract
The invention relates to a method of transmitting data over a mobile telephone speech channel between a radio telephone terminal having a type of source encoding and a data transceiver unit via a mobile telephone network supporting at least one mode of communication without transcoding that can be set up between two mobile telephones having at least one type of source encoding in common. In the method, while negotiating the mode of communication between said radio telephone terminal and said data transmitter and/or receiver unit, the transmitter and/or receiver unit sends one of the types of source encoding available to said terminal to the terminal to engage said mode of communication without transcoding. Thereafter, data is transmitted over the mobile telephone network in frames reserved for speech signals encoded using the type of source encoding selected for the mode of communication.
