Problems solved by technology

[0003] In the prior art, since there is no information about the mutual connection between function maintenance functional entities in Y.2111, when the SCF initiates a QoS request, there is a possibility that the QoS request cannot be sent to the PD-FE that can handle the QoS request. At this time , the PD-FE that receives the QoS request needs to pass this information to all PD-FEs, which increases the processing of PD-FE and network information traffic; at the same time, if the PD-FE that receives the QoS request cannot determine which TRC-FE When processing QoS control requests, QoS control information will also be sent to all TRC-FEs, which also increases the processing of TRC-FEs
In this way, already tense network resources will be wasted

Embodiment Construction

[0018] Referring to FIG. 2 , it illustrates the network architecture of the system for implementing QoS requested by the service control function provided by the present invention. As shown in the figure, referring to FIG. 1 at the same time, it can be seen that the system provided by the present invention has one more functional unit, namely DS-FE, compared with the prior art. The DS-FE is connected to the PD-FE. It should be noted that the DS-FE may be a functional entity in the concept of hardware or a functional entity in the sense of software. Of course, the NGN network architecture also includes other network elements, but they are not involved in the present invention, so they are omitted. Those skilled in the art should understand this omission, and can know other network elements by referring to standards.

[0019] Referring to FIG. 3 , an internal structure diagram of the DS-FE is illustrated. As shown in the figure, DS-FE includes a neighbor PD-FE table, which sto...

Abstract

The method includes steps: (1) SCF triggers QoS request, and sends initial request for resources to PD-FE; (2) PD-FE determines whether the initial request for resources can be accomplished locally; if yes, accomplishing the initial request for resources, and ending; otherwise, sending command for querying neighbors to discovery selection functional element, i.e. DS-FE; (3) through querying PD-FEtables of neighbors, DS-FE responds information of practical PD-FE capable of accomplishing the initial request for resources to PD-FE; (4) based on practical PD-FE information, PD-FE accomplished the initial request for resources. The method reduces network flow, and saves network resources. The invention also discloses system and device of using the method.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for requesting QoS (Quality of Service) by a Service Control Function (SCF) in a Next Generation Network (NGN). Background technique [0002] In the definition of RACF (Resource Admission Control Function, resource admission control function) of Y.2111 of the NGN standard organization ITU-T, it defines two control function entities of RACF-PD-FE (Policy Decision Function Entity, policy decision function entity ), TRC-FE (Transport Resource Enforcement Function Entity, transport resource control function entity) and two transport function entities-PE-FE (PolicyEnforcement Function Entity, policy enforcement function entity), TRE-FE (TransportResource Enforcement Function Entity, transport resource enforcement functional entities) and also defines the reference points between these functional entities. In Y.2111, it is stated that there a...
