Abstract

La présente divulgation concerne un procédé (500) visant à changer des règles de politique dans un réseau de communication (106), le procédé (500) consistant à recevoir (502) une demande provenant d'un équipement utilisateur (UE) (102). Le procédé consiste à extraire (504) une pluralité de paramètres associés à la demande reçue pour générer une liste de règles de politique. Le procédé consiste à fournir (506) au moins un indicateur mutuellement exclusif pour chaque règle de politique dans la liste générée de règles de politique et à envoyer (508) une règle de politique à une fonction de gestion de session (SMF) (110) après avoir déterminé que l'indicateur mutuellement exclusif fourni est vrai pour la règle de politique.
