Abstract

La présente invention concerne un procédé de communication et un appareil de communication. Le procédé de communication comprend : la réception, par un premier terminal, de premières informations, les premières informations étant utilisées pour donner l'ordre à un premier terminal d'exécuter une opération de service basé sur la proximité (ProSe) entre des dispositifs terminaux lorsque le premier terminal détecte qu'un premier événement a été déclenché, l'opération ProSe correspondant au premier événement ; et lorsqu'il est détecté que le premier événement a été déclenché, l'exécution de l'opération ProSe par le premier terminal. Dans les modes de réalisation de la présente demande, un mécanisme de déclenchement d'événement est présenté et un premier événement est fourni à un premier terminal de sorte que le premier terminal exécute une opération ProSe, qui correspond au premier événement, uniquement lorsque le premier événement est déclenché, ce qui permet d'éviter que le premier terminal réalise en continu des opérations ProSe associées et donc de réduire la consommation de ressources du premier terminal.
