Problems solved by technology

[0022] In the existing PULL mode resource admission control method, since there may be multiple PD-FEs based on different service scenarios, there are multiple-to-single and single-to-many In this scenario, as shown in the network diagram shown in Figure 5, in this case, because the PD-FE did not notify the PE-FE or the bearer control layer of the authorization information of the service flow in the service authorization process before the resource reservation request TRC-FE, so PE-FE or bearer control layer TRC-FE will not be able to know which PD-FE authorized the service flow that initiated the resource reservation request after receiving the resource reservation request, and cannot select the correct PD-FE to complete Resource Reservation Request Process

Embodiment 1

[0054] As shown in Figure 6, the service authorization process in this embodiment includes the following steps:

[0055] (601) After receiving the service establishment signaling message, the SCF triggers the QoS authorization process;

[0056] (602) The SCF sends a resource initialization message to the PD-FE, requesting service authorization;

[0057] (603) The PD-FE performs QoS resource authorization on the service request;

[0058] (604a, b) After the PD-FE authorizes the service request, it sends an authorization notification message to the relevant PE-FE and the bearer control layer TRC-FE, and notifies the PE-FE and the bearer control layer TRC-FE of the authorization information of the service flow ;

[0059] After receiving the authorization notification message, PE-FE and bearer control layer TRC-FE associate the service flow authorization information with the PD-FE that sent the notification message, and establish a correspondence table between PD-FE and service ...

Embodiment 2

[0086] As shown in Figure 9, the service authorization process of this embodiment includes the following steps:

[0087] (901) After receiving the service establishment signaling message, the SCF triggers the QoS authorization process;

[0088] (902) The SCF sends a resource initialization request message to the PD-FE, requesting service authorization;

[0089] (903) The PD-FE authorizes the QoS resource for the service request, and allocates an authorization token for the session, and the authorization token includes the identification information of the PD-FE;

[0090] The above PD-FE identification information may be the IP address or ID of the PD-FE. For example, the authorization token may be composed of the IP address of the PD-FE plus a serial number of a service flow. If the identification information is not the IP address of the PD-FE, a mapping table between the identification information of the PD-FE and the IP address of the PD-FE needs to be configured on the PE-...

Abstract

The invention discloses a method for controlling resources acceptation, comprising the following steps that: in the process of service authorization of the control of the resources acceptation in the PULL mode, after a PD-FE authorizes a service request, the authorization information of the authorization service flow is notified to a PE-FE and a TRC-FE; after the PE-EF and the TRC-FE receive the authorization information, the correspondence between the PD-FE and the authorization information of the authorization service flow is established; after the PE-EF or the TRC-FE receives the resources reservation request of the authorization service flow, the PD-FE is chosen according to the correspondence and is interactive. Compared with the prior art, the method for controlling the resources acceptation of the invention can complete the resources reservation request flow for the PD-FE which initiates the service flow authorization of the resources reservation request after the PE-EF or the TRC-FE receives the resources reservation request of the service flow.

Description

technical field [0001] The present invention relates to the field of communication, and more specifically relates to a method for resource admission control in NGN (Next Generation Network, Next Generation Network). Background technique [0002] In NGN, because the bearer network adopts packet technology, especially IP (Internet Protocol, Internet Protocol) technology, the problem in QoS (Quality of Service, quality of service) is particularly prominent. The ITU (International Telecommunication Union, International Telecommunication Union) proposes to use RACF (Resource and Admission Control Function, resource admission control function) to solve the QoS problem of the NGN bearer network. [0003] The main function of RACF is to perform resource admission control based on operating policy rules and user subscription QoS information and available resources within the network. It shields the difference of the bearer layer from the application layer, and maps the QoS attribute...
