Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 2 As shown, the resource reservation system of this embodiment is based on the unicast resource processing system, and a new resource allocation function entity RAF is added in the bearer control layer, including CPE (client equipment), AF (Application Function, application layer) Functional entity), RAF (Resource AllocateFunction, resource allocation functional entity), RACS (Resource and Admission ControlSubsystem, resource admission control sublayer), TL (Transport Layer, transport layer entity), where:

[0028] The AF is used to analyze the resources required by the service request of the client equipment, and send a resource allocation request to the RAF;

[0029] RAF is used to allocate and reserve unicast and multicast resources, and forward resource allocation requests and responses. In addition, RAF ca...

Abstract

The invention discloses an implement method of resource allocation in the NGN network and a system, realizing multicast service. The system comprises RACS, TL and a resource allocation functional entity RAF, distributing unicast resource in advance for unicase service according to resource state report of received transmission layer, and returning allocating result to RACS, used for determining whether the unicast service request is successful according to alternation of the preassigned resource with TL when the user device requests the unicast service. The method comprises: after resource allocation functional entity ,namely RAF receives the status report of the resource of the transmission layer, allocating the unicast resource in advance for the unicast service, and returning the allocating result to a resource admitting control sub-systems namely RACS; when the user device requests the unicast service, RACS determines whether the unicast service request is successful according to the preassigned resource and the transmission layer entity namely TL alternation.

Description

technical field [0001] The invention relates to the communication field, in particular to the resource allocation in the NGN network. Background technique [0002] In NGN (Next Generation Network), in order to provide end-to-end service quality assurance for services, a new Resource and Admission Control Sublayer (Resource and Admission Control Subsystem, RACS) is added between the service control plane and the transport plane, responsible for the transmission Admission control of network resources is mainly responsible for the processing of unicast resources. The system architecture is as follows: figure 1 shown. With the development of multicast services such as IPTV in various places, the current RACS architecture can no longer meet service requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method and system for realizing resource allocation in an NGN network, which provides the possibility for ...
