Abstract

A method for implementing resources reservation in an access configuration mode in an NGN, including: when a subscriber accesses a network, an NAAF sending a resources request message to a resources mediation PDF; after receiving the resources request message, the resources mediation PDF making an admission decision according to network operator policy rules and availability of resources, send an admission installation command to a BGF, setting and keeping the corresponding admission decision parameters information in the BGF. Thus, the BGF performs packet forwarding operations as classifying, marking, shaping, and discarding on the user traffic entering the network according to the admission decision information so as to ensure the QoS class required by the user. Therefore, an applicable solution for implementing resources reservation in the access configuration mode in the NGN is provided.

Claims

1. A method for implementing resources reservation in an access configuration mode in a next generation network (NGN), comprising:

when a user terminal accesses the network, a network access additional function entity (NAAF) sending a resources request message to a resources mediation policy decision function entity (PDF) according to a subscriber service level agreement in a subscriber configuration file, wherein the resources request message carries resources requirement parameters information requested by a user traffic;

after receiving the resources request message, the resources mediation PDF checking whether the corresponding resources request is consistent with related network operation policy rules, and checking whether there are available resources meeting the resources requirement in the 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), and setting corresponding admission decision parameters information in the BGF; and

the BGF performing forwarding operations on the user traffic entering the network according to the admission decision parameters information.

2. The method according to claim 1, further comprising:

after receiving a resources modification request message, the resources mediation PDF checking whether the corresponding resources modification request is consistent with the network operation policy rules, and checking whether there are available resources meeting the resources requirement in the related transport network, and making an admission decision for the corresponding resources modification request according to a checking result;

if the corresponding resources request is admitted, the resources mediation PDF sending an admission modification command to the BGF, and modifying corresponding admission decision parameter information in the BGF; and

the BGF performing forwarding operations on the user traffic entering the network according to the modified admission decision parameters information.

3. The method according to claim 1 further comprising:

after receiving the resources request message or the resources modification request message, the resources mediation PDF deciding access networks and core networks related to the user traffic, interacting with a transport resources control function entity (TRCF) in the access networks and the core networks, checking the availability of transport resources within the networks, and sending the admission installation command or the admission modification command to the BGF after deciding that the resources are available.
