A list of routing objects is associated with each switching node of a telecommunication network. This list includes a plurality of routing objects whose parameters are described in tree-structure form. Responsive to a call message received by said node, routing objects of the list whose parameters have tree-structure descriptions included in tree-structure descriptions of signalling elements of the call message are searched. Among all these routing objects, an object having a maximum gain is selected so as to route a communication associated to said call message according to a downstream path parameter of the object selected. Gains for each object are computed as a function of charge recorder information. New objects are created by incrementing by one level the tree-structure of each parameter of said maximum gain object. Each object whose difference in gain per communication with the maximum gain object is high is maintained. The other objects, which are less advantageous from an economic point of view, are deleted.
