Abstract

Des modes de réalisation de la présente demande concernent un procédé et un appareil de traitement de communication dans un scénario de partage de réseau. Le procédé comprend les étapes suivantes : un dispositif de réseau central obtient des informations de capacité d'un nœud relais, les informations de capacité comprenant au moins deux réseaux mobiles terrestres publics (PLMN) pris en charge par le nœud relais ; le dispositif de réseau central détermine, en fonction des informations de capacité, un second nœud hôte qui partage une ressource d'interface radio du nœud relais avec un premier nœud hôte, le premier nœud hôte et le second nœud hôte prenant en charge au moins l'un des au moins deux PLMN, et le premier nœud hôte et le second nœud hôte fournissant simultanément des services de communication de différents PLMN pour une interface radio du nœud relais ; et le dispositif de réseau central envoie des premières informations d'indication au premier nœud hôte, les premières informations d'indication comprenant des informations d'identifiant du second nœud hôte. En utilisant les modes de réalisation de la présente demande, un service de partage d'un nœud relais peut être mis en œuvre même lorsqu'il n'y a pas de dispositif réseau prenant en charge le même PLMN partagé que le nœud relais à proximité du nœud relais.
