Abstract

Les modes de réalisation de la présente invention concernent un procédé d'échange local de données qui comprend les étapes suivantes : le côté réseau obtient des premières informations d'adresse pendant le processus d'établissement du support avec un terminal demandeur, et obtient des secondes informations d'adresse pendant le processus d'établissement du support avec un terminal de réception; lorsque les premières informations d'adresse sont les mêmes que les secondes d'informations d'adresse, le terminal demandeur et le terminal de réception sont liés, et les données sont échangées localement, puis envoyées par le terminal demandeur ou le terminal de réception liés sur les supports. Grâce aux modes de réalisation de la présente invention, sans l'analyse de la station de base de chaque paquet de données montant, les temps d'échange local de la station de base pour les paquets de données montants sont réduits, l'efficacité est améliorée, et donc la charge de la station de base est réduite.
