Abstract

L'invention concerne un procédé, un système et un dispositif de suppression de support. Ce procédé consiste à : recevoir un message de demande, et, selon le message de demande contenant les informations d'indications, distinguer un détachement ou une désactivation; selon les informations d'indications, traiter l'opération de détachement et l'opération de désactivation. La distinction effectuée, par l'intermédiaire des informations d'indication, entre le flux de détachement et le flux de désactivation, permet d'établir une interaction unique entre le MME et le S-GW, ce qui permet de compléter le flux de détachement et le flux de désactivation.
