A video-communication service in a mobile communication network using a packet-switched connection, in which a monitoring of a radio channel portion is performed at the mobile stations of the users involved in the communication. Parameters of the video communication (e.g. the coding rate) are adjusted based on a result of the monitoring of the radio channel portion.

Video-communication in mobile networks

For establishing a multimedia session with a remote user's terminal, a terminal starts a signaling intended to establish the multimedia session addressed to the remote user's terminal. Predetermined acknowledgement messages indicate to the terminal and to the remote terminal that the multimedia session is established. The terminal and/or the remote terminal run at least a module of a multimedia application before reception of the predetermined acknowledgement messages.
