  • the policy decision entity 1401 of the home network is configured to send a QoS policy to the policy decision entity 1402 of the visited network; the policy decision entity 1402 of the visited network is used as the access node according to the policy and the QoS policy sent by the home network. 1403: Assign a mapped QoS policy, and send the mapped QoS policy to the access node 1403, where the policy is an allocation rule of the QoS parameter of the visited network;
  • the decision entity 1402 of the visited network is specifically configured to modify the QoS policy sent by the home network according to the policy, the attribute information of the user terminal, and the QoS policy sent by the home network, to obtain the mapped QoS policy.
  • the attribute information of the user terminal is: the user's international mobile device identity code IMEI, the home public land mobile communication network PLMN, the current time, the quality of service classification identifier QCI, the allocation and retention priority ARP, the subscription information, the terminal type, and/or Or the access point name APN;
  • the access node 1403 is configured to allocate a QoS parameter according to the received QoS policy, and send the QoS parameter to the network element 1404 of the access network;

Abstract

L'invention concerne un procédé de traitement de paramètres de qualité de service (QoS), qui comprend les étapes suivantes: un nœud d'accès reçoit des paramètres de QoS et attribue les paramètres de QoS personnalisés selon une stratégie, constituée par la règle d'attribution des paramètres de QoS du réseau dans lequel le nœud d'accès se situe, et les paramètres de QoS reçus ; et envoie les paramètres de QoS personnalisés à l'élément de réseau du réseau d'accès. Les formes de réalisation de l'invention concernent un système, un nœud d'accès et une entité de décision de stratégie servant à traiter les paramètres de QoS. Le nœud d'accès attribue les paramètres de QoS personnalisés au réseau d'accès afin de permettre au réseau d'accès dans lequel le terminal se situe de commander la QoS du terminal d'utilisateur selon les paramètres personnalisés. Ce procédé est plus flexible que le procédé existant destiné à assurer la qualité du service et à commander celle-ci.
