1. A method of performing a communication between a first and a second user in a mobile communication network, the first and the second users being provided with respective first and second mobile stations, comprising:
- establishing a packet-switched connection between said first and said second mobile station, the packet switched connection comprising at least one radio channel portion;
transmitting a video component from said first to said second mobile station on said packet-switched connection;
continuously monitoring, during the transmitting, a quality of said at least one radio channel portion; and
adjusting, by the first mobile station or the second mobile station during the transmitting, at least one parameter related to quality of said video component as a function of an available bandwidth on the packet-switched connection, based on a result of said monitoring.

Abstract
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.

25. A mobile station adapted for performing a communication in a mobile communication network, comprising:
-
a first unit adapted to code/decode a video component of the communication; a second unit associated with the first unit, the second unit being adapted to establish at least a packet-switched connection comprising a radio channel portion, and to transmit said video component on said packet-switched connection; and a third unit adapted to continuously monitor, during the transmitting, a quality of said radio channel portion, wherein said first unit is associated with said third unit and said first unit is also adapted to adjust, during the transmitting, at least one parameter related to quality of said video component as a function of an available bandwidth on the packet-switched connection, based on an output of said third unit. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
