A method and a device for matching a quantization table of data representative of a radio signal received by a radio antenna of a mobile network. The method includes: obtaining an item of information representative of a channel decoding error rate of a decoded quantized demodulated signal from a demodulation of the radio signal received by the antenna, the demodulated radio signal having been quantized by the quantization table, and the quantized demodulated radio signal having undergone a channel decoding; matching the quantization table when the channel decoding error rate is higher than a determined threshold; and transmitting an item of information representative of the matching of the quantization table to a channel decoding device or to a demodulation device.

A method for quantizing data representative of a radio signal received by a radio antenna of a mobile network. The method includes: demodulating the radio signal received by the antenna, providing a demodulated signal; scalar quantizing each value of the demodulated signal using a quantization table selected according to a channel coding level used to transmit the radio signal, providing a quantized demodulated signal; and transmitting the quantized demodulated signal to a channel decoding module.

Distributing a configuration to a first terminal, including establishing, on initiative of the first terminal, a connection between the first terminal and a server, which is configured to redirect connection requests received by the server on a communication port to the first terminal. The communication port is derived from an identifier of the first terminal received in a message establishing the connection. When the identifier of the terminal is associated with a plurality of terminals, the method includes generating and storing control data in association with the identifier of the terminal, transmitting, via the connection, a control message to the first terminal, which includes the control data, receiving, from a second terminal, a confirmation message including the control data and an identifier of the second terminal, and when the second terminal is a trusted terminal, and transmitting customized parameters to the first terminal to access the server.

A method of video conference communication between N terminals of N users is described. The method can be implemented by one of the N terminals, and can include receiving, from a processing device, N audiovisual streams respectively transmitted by the N terminals, N items of voice activity information of the N users, respectively associated with N corresponding user identifiers, each of the N items of information assuming a first or a second value respectively representing the presence or absence of voice activity. The method can also include determining, for at least one of the N users, whether or not the information is at the same value from a certain time. The method can also include requesting, from the device upon determining that the information is at the first value from this time, a stream associated with the user as the main stream to be displayed, receiving, and displaying the main stream.
