Method for Implementing Resources Reservation in a Proxy-Requested Mode in Next Generation Network
First Claim
1. A method for implementing resources reservation in a proxy-requested mode in a next generation network (NGN), comprising:
- an application function entity (AF) sending a resources request message to a resources mediation policy decision function entity (PDF), wherein the message carries resources requirement parameters information needed by a user traffic;
after receiving the resources request message, the resources mediation PDF checking whether the corresponding resources request is consistent with a related subscriber configuration file and related network operation policy rules, checking whether there are idle and available resources meeting requirements in related transport networks, and making an admission decision for the corresponding resources request according to a checking result;
if the corresponding resources request is admitted, the resources mediation PDF sending an admission installation command to a border gateway function entity (BGF), setting and keeping corresponding admission decision parameters information in the BGF; and

Abstract
A method for implementing resources reservation in a proxy-requested mode in an NGN, includes: an AF entity sending a resources request message carrying resources requirement parameters information on behalf of a user to a resources mediation PDF; the resources mediation PDF making an admission decision according to network operation policy rules, subscriber configuration files, and availability of transport resources; if the corresponding resources request is admitted, the resources mediation PDF sending an admission installation command to a BGF, setting and keeping corresponding admission decision parameters information in the BGF; the BGF forwarding subscriber traffic entering networks according to the admission decision parameters information to ensure QoS class requested by the user. According to the present invention, terminals with various QoS negotiation capabilities are supported, and QoS requirement parameters of the media flows are negotiated or are determined by the AF entity according to the media flows and service operation policies.
