Resource admission control method and policy decision functional unit

Abstract

The invention discloses a resource receiving control method, which includes that a strategy decision-making function unit receives a service request. According to the service request, the strategy decision-making function unit identifies a load-bearing control module; and selects corresponding service logic according to the load-bearing control module; and processes the resource receiving and control. In the technical proposal of the invention, no matter requesting resource to the fixed access net defined in a TISPAN, or to the wireless access net defined in a 3 GPP, the load-bearing control modules are all identified by the strategy decision-making function unit xPDF. The strategy decision-making function unit xPDF selects corresponding service logic and processes the resource receiving and control. The xPDF hides the detail of the access net from an AF and simplifies the networking proposal; so the system maintenance becomes simple and convenient.

Description

technical field [0001] The invention relates to the communication field, in particular to a resource admission control method and a policy decision-making functional unit. Background technique [0002] The resource and admission control subsystem proposed by ETSI TISPAN belongs to the bearer control layer, which realizes policy control, resource reservation, admission control, access, aggregation, network address port / protocol translation in the core network, resource and admission control subsystem framework As shown in Figure 1, where: [0003] RACS is a resource and admission control sub-system, including SPDF (service-based policy decision function) unit and A-RACF (access resource and admission control function, access-resource andadmission control function) unit, AF (application function, application function) unit, NASS (network attachment subsystem, network attachment sub-system), AN (access node, Access node), RCEF (resource control execution function, resource con...
