Abstract: A method for locating a quality of service problem implemented on a terminal during a multi-media session between two terminals over a communication network, which includes at least one media gateway that is able to retransmit media data packets without particular processing according to a “router mode” of management. The terminals obtain a first quality of service data item relating to the multi-media session. Following a change in the mode of management to a “relay mode” in which the multi-media session initially established between the terminals is split into two separate multi-media sessions, it includes: obtaining of a second quality of service data item relating to one of the two multi-media sessions established following the change in the mode of management of the media gateway; comparing the first and second quality of service data items; and locating the quality of service problem depending on the result of the comparison.

Abstract: The invention relates to a method for communicating between at least a first terminal (T1) and a second terminal (T2). When a user of the first terminal consults at least one multimedia content via an interface associated with the first terminal, information representative of said multimedia content is stored in a first storage space of the first terminal or of a remote server. Following the establishment of the communication (E_COM) between the first terminal and the second terminal, for each multimedia content displayed on the interface associated with the first terminal, the second terminal (E10) receives information representative of the multimedia content comprised in the first storage space, and obtains (E11) said multimedia content, using said received representative information.
