Embodiment Construction

[0038] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0039] In the scenario of fixed-mobile convergence (FMC fixed-mobile convergence), the service layer needs to control both the fixed access network and the mobile access network through bearer control. Therefore, it is necessary to support the integration of the fixed access solution and the mobile access solution. Make the bearer control layer provide a unified interface to the application layer, shield the difference of different access methods from the application function, shield the different control methods for various access methods, and shield the fixed access scheme and the mobile access scheme in resource control and admission control. , Billing differences, and can be compatible with previous resource control and admission control methods. This solves the problem of complex networking and maintenance caused by the need to d...

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...
