Embodiment Construction

[0045] To enable a Border Gateway Function (BGF) entity that has allocated service resources (such as NAT translation) to a call when a Network Attachment Subsystem (NASS) or Resource Control Enforcement Function (RCEF) entity triggers an event related to the withdrawal of a resource reservation The service resource can be reclaimed in time. In the present invention, the service-based policy decision function (SPDF) entity judges whether the BGF entity has allocated service resources for the session, and notifies the BGF to release and reclaim the service when it is determined that the session has allocated service resources. resource.

[0046] The notification message sent by the A-RACF entity to the SPDF entity contains resource-related contexts, which are generated during the process of requesting resources from the AF entity to the SPDF entity, and are stored on the AF entity and the A-RACF entity (where This context information is not saved on SPDF). When the SPDF select...

Abstract

This invention discloses one materials withdraw method based on material load control sub system, which comprises the following steps: triggering and withdrawing materials relative affairs from sub system or materials control execution function to inform interface layer material load control function part; the A-RACF part informs SPF part based on business strategy; SPDF part informs function to withdraw materials to test BGF as dialogue and to inform BGF function release and recycle business materials. This invention also discloses one network device.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource revocation method and device based on a resource admission control subsystem. Background technique [0002] With the continuous increase of Internet scale, various network services emerge one after another, and advanced multimedia communication systems emerge in endlessly. Since real-time services are sensitive to characteristics such as network transmission delay and delay jitter, when there are high-bursty File Transfer Protocol (FTP) or Hypertext Transfer Protocol (HTTP) services containing image files on the network, real-time services will be greatly affected; on the other hand, because multimedia services take up a large amount of bandwidth, it is difficult to obtain reliable transmission of key services to be guaranteed by the existing network. Therefore, various Quality of Service (QoS) technologies emerge as the times require. IETF has propose...
