Abstract

Des modes de réalisation de la présente demande divulguent un procédé d'identification de modèle et un dispositif, qui peuvent être appliqués à un système de communication. Le procédé comprend les étapes suivantes : un premier nœud détermine une première relation de mise en correspondance, la première relation de mise en correspondance étant une relation de mise en correspondance entre un modèle et un premier identifiant de modèle du modèle, et le premier identifiant de modèle étant un identifiant de modèle local du modèle sur le premier nœud ; et le premier nœud envoie la première relation de mise en correspondance à un second nœud, et le second nœud détermine, selon la première relation de mise en correspondance, un premier modèle devant être traité et réalise des opérations associées sur le premier modèle. La mise en correspondance entre le modèle et l'identifiant de modèle local du modèle est établie, la première relation de mise en correspondance est transmise au second nœud, et à condition que l'identifiant de modèle local soit transmis dans un réseau sans fil, le second nœud peut déterminer l'objectif du modèle identifié sur la base de l'identifiant de modèle local, un identifiant de modèle global du modèle n'a pas besoin d'être transmis dans le réseau sans fil, le risque de falsification de l'identifiant de modèle global lors de la transmission peut être réduit, et le temps de transmission et le surdébit de signalisation sont réduits.
