Abstract

La présente invention concerne un procédé et un dispositif destinés à déterminer une façon de supporter un service. La solution technique consiste en ce que : selon des informations d'un terminal cible au sujet du service courant, un dispositif de réseau détermine des informations de distribution au sujet de chaque terminal cible correspondant aux informations du terminal cible ; et, selon les informations de distribution au sujet de chaque terminal cible du service courant, le dispositif de réseau détermine une façon de supporter un service correspondant aux informations de distribution en tant que façon de supporter un service pour le service courant. Selon la solution technique, le dispositif de réseau peut déterminer, selon les informations de distribution se rapportant à chaque terminal cible du service courant, une façon de supporter un service correspondant à la façon de distribution correspondant aux informations de distribution. En comparaison avec l'art de la technique, on évite le problème selon lequel des ressources de réseau sont gaspillées par une non-correspondance entre la façon de supporter un service et la situation réelle de distribution du terminal cible, améliorant ainsi le taux d'utilisation des ressources du réseau.
