La présente demande se rapporte au domaine technique des communications, et concerne un procédé et un appareil de communication, capables d'améliorer la précision d'un dispositif terminal correspondant à une règle de politique de sélection d'itinéraire d'équipement utilisateur (URSP) sur la base d'informations d'application, ce qui permet d'améliorer un taux de réussite d'établissement de session et un taux de réussite de transmission de données, et d'améliorer les performances de communication. Le procédé comprend les étapes suivantes : un dispositif terminal acquiert des premières informations d'une première application sur la base d'un premier trajet d'acquisition, et met en correspondance les premières informations d'application avec la règle URSP du dispositif terminal ; lorsque les premières informations d'application ne correspondent pas à la règle URSP, acquiert des secondes informations d'application de la première application sur la base d'un second trajet d'acquisition ; et met en correspondance les secondes informations d'application avec la règle URSP.
