Abstract

La présente demande divulgue un procédé de découverte T-EES, ainsi qu'un appareil associé. Le procédé de découverte consiste à : envoyer un message de demande à un premier ECS ou à un second ECS, la demande étant utilisée pour demander l'acquisition d'informations d'un T-EES ; et recevoir un message de réponse qui est envoyé par le premier ECS ou le second ECS, le message de réponse comprenant des informations d'un premier EES, et les informations du premier EES comprenant au moins les informations du T-EES. À l'aide des modes de réalisation de la présente demande, la communication entre un S-EES et un T-EES peut être réalisée, de telle sorte que les S-EES peuvent envoyer une demande de découverte d'EAS au T-EES lorsqu'une migration de contexte d'application est effectuée, ce qui permet d'éviter la défaillance de la migration de contexte d'application.
