Abstract

La présente invention porte, dans les modes de réalisation, sur un procédé, sur un appareil et sur un système permettant une gestion utilisateur et une maintenance d'état et se rapporte au domaine de la communication. L'invention vise à résoudre le problème de faiblesse de la qualité de service du réseau après un transfert, la faiblesse étant due au transfert de l'équipement utilisateur (UE) qui effectue un service d'urgence. Le schéma technique proposé par l'invention consiste à obtenir des informations d'indication de restriction de service lorsque l'UE effectue un transfert de service d'urgence entre un réseau source et un réseau cible (201) et déterminer l'état de l'UE dans le réseau cible selon les informations d'indication de restriction de service (202).
