Abstract
A method of operating a mobile telephone that is taken up in a data transmission network, which method involves at least one encoding and decoding algorithm for converting analog speech data into digital data and vice versa; according to this method at least one further encoding and decoding algorithm is transmitted to the mobile telephone via a data transmission link that is established between the mobile telephone and the network, which algorithm is received by the mobile telephone and stored in a non-volatile memory so as to be used for data conversion after the implementation.
