L'invention porte sur un procédé et un dispositif de traitement de service. Le procédé comprend les opérations suivantes : un terminal reçoit une politique de fonction de découverte et de sélection de réseau d'accès (ANDSF) envoyée par le côté réseau, la politique ANDSF comprenant la condition de migration d'un service ; le terminal détecte que le service courant satisfait la condition de migration ; et le terminal fait migrer le flux de service relatif au service courant vers d'autres dispositifs côté réseau. L'application de la présente invention peut résoudre le problème selon lequel des systèmes 3GPP courants ne peuvent pas effectuer une différenciation de données sur les services dans le réseau de manière à effectuer un traitement de classification.
