La présente divulgation se rapporte à un procédé et à un système permettant d'effectuer une procédure d'interdiction pour un ou plusieurs dispositifs utilisateur dans une zone de rapport de présence prédéfinie (PRA). La présente divulgation consiste à recevoir, par un serveur de réseau central, des informations de zone pour l'application de la procédure d'interdiction. Le procédé consiste à identifier, par le serveur de réseau central, un ensemble d'un ou plusieurs deuxièmes serveurs, en fonction des informations de zone. Le procédé consiste à envoyer, par une interface utilisateur au niveau desdits deuxièmes serveurs l'implémentation d'une fonction de gestion de session (SMF) à un ou plusieurs premiers serveurs implémentant une fonction de commande de politique (PCF). Le procédé consiste à recevoir en provenance du premier serveur au niveau du deuxième serveur, une politique mise à jour relative à l'au moins une instruction de déclenchement de PRA envoyées par une interface utilisateur au premier serveur. Le procédé consiste à envoyer, par le deuxième serveur à un troisième serveur l'implémentation d'une fonction de plan utilisateur (UPF).
