The protocol consists, in particular, in updating, in all the telecommuniction network terminals and nodes involved in a given call, a matrix corresponding to the state of each terminal (TA, TB, TC) which participates in the call being processed, in relation to each connection (C1, C2, C3) established for the call being processed. The matrix distinguishes a plurality of fine states within the active state of each of the terminals and nodes involved in said call. The matrix is generally updated by means of a message which is sent to the whole network when an operation is in fact performed in one of the terminals, and when this operation modifies the state of the call, or the state of a connection estblished for this call, or the state of a terminal participating in said call.
