Method for managing multi-stream sessions during which a terminal (Ti) and a server (Sj) exchange, during a multi-stream session, information blocks organized into several different streams comprising: a signalling stream dedicated to the transport of information blocks which are dedicated to signalling and are used to establish the sessions and to close the multi-stream sessions; and one or more streams distinct from the signalling stream, at least one distinct stream transporting useful data blocks comprising data linked with one or more services provided by the server, characterized in that said method comprising the storage in a data structure: - of first data determined on the basis of an information block dedicated to signalling and originating from the terminal (Ti), said first data allowing to identify the signalling stream which transports said information block dedicated to signalling, said signalling stream belonging to the session; - of second data in conjunction with said first data, said second data being determined on the basis of at least one other information block dedicated to signalling and transported by the same signalling stream, said second data allowing to identify the other distinct stream or streams of the session, the first data, and the second data stored in the data structure linking together in the same session the signalling stream and the distinct stream or streams. a signalling stream dedicated to the transport of information blocks which are dedicated to signalling and are used to establish the sessions and to close the multi-stream sessions; and one or more streams distinct from the signalling stream, at least one distinct stream transporting useful data blocks comprising data linked with one or more services provided by the server, characterized in that said method comprising the storage in a data structure: - of first data determined on the basis of an information block dedicated to signalling and originating from the terminal (Ti), said first data allowing to identify the signalling stream which transports said information block dedicated to signalling, said signalling stream belonging to the session; - of second data in conjunction with said first data, said second data being determined on the basis of at least one other information block dedicated to signalling and transported by the same signalling stream, said second data allowing to identify the other distinct stream or streams of the session, - of first data determined on the basis of an information block dedicated to signalling and originating from the terminal (Ti), said first data allowing to identify the signalling stream which transports said information block dedicated to signalling, said signalling stream belonging to the session; - of second data in conjunction with said first data, said second data being determined on the basis of at least one other information block dedicated to signalling and transported by the same signalling stream, said second data allowing to identify the other distinct stream or streams of the session, the first data, and the second data stored in the data structure linking together in the same session the signalling stream and the distinct stream or streams.
