Abstract

La présente invention se rapporte au domaine technique des ordinateurs. L'invention concerne spécifiquement un procédé de gestion de processus, et un dispositif électronique et un support de stockage, qui visent à résoudre le problème d'un effet de sommeil qui est influencé parce qu'un processus en arrière-plan d'un système est fréquemment réveillé après sommeil du processus en arrière-plan de système. À cet effet, le procédé de gestion de processus selon la présente invention est appliqué à une couche de structure de système, et le procédé consiste à : en réponse à une demande de réveil reçue pour un processus en sommeil, déterminer un niveau d'importance d'un processus initiant une demande de réveil ; si le niveau d'importance du processus initiant la demande de réveil appartient à un premier niveau d'importance, réveiller un processus en sommeil correspondant, qui initie la demande de réveil, pour la première fois ; et après que le processus en sommeil soit réveillé et reste dans un état de réveil pendant une première durée prédéfinie, déterminer si le processus en sommeil, qui est réveillé, peut être détecté par un utilisateur, et exécuter une opération correspondante sur la base d'un résultat de détermination. De cette manière, l'effet de sommeil d'un processus en arrière-plan d'un système est mieux assuré, de la mémoire est libérée, et ainsi les performances du système sont améliorées, et la consommation d'énergie est réduite.
