[0003]目前,资源接纳控制系统主要包括Tispan定义的资源接纳控制子系统(ResourceAdmiss1n and Control Subsystem,简称为RACS)和国际电信联盟(Internat1nalTelecommunicat1n Un1n,简称为ITU)定义的资源接纳控制功能(Resource andAdmiss1n ControlFunct1ns,简称为RACF)。 Resource and Admission Control Function [0003] Currently, the RACS mainly includes a resource admission control subsystem defined Tispan (ResourceAdmiss1n and Control Subsystem, simply referred to as RACS) and the International Telecommunication Union (Internat1nalTelecommunicat1n Un1n, abbreviated as ITU) defined (Resource andAdmiss1n ControlFunct1ns, referred to as RACF).

[0004] 图1为Tispan定义的RACS的详细框架,主要包括:业务策略决策功能实体(Service Policy Decis1n Funct1n,简称为SPDF),基于业务层提供的业务信息等作出基于业务的最终策略决策;通用资源接纳控制功能(x-RACF),负责用户的接入接纳控制以及资源控制;资源控制执行功能(Resource Control Execute Funct1n,简称为RCEF),负责执行接收到的策略;边界网关功能(Border GatewayFunct1n,简称为BGF),负责策略执行以及端口地址转换;基本传输功能(Base Transport Funct1n,简称为BTF),为数据传输节点;应用业务功能(Applicat1n Funct1n,简称为AF),用于提供具体的应用业务,例如多媒体系统(IMS)等;网络附属子系统(NetworkAttachment Subsystem,简称为NASS),负责提供用户签约数据等信息。 [0004] FIG. 1 is a detailed framework of RACS Tispan defined, comprises: a service policy decision function entity (Service Policy Decis1n Funct1n, referred to as the SPDF), make the final policy decision based service based on traffic information service layer provides; universal resource and admission control function (x-RACF), responsible for admission control user access and resource control; resource control Enforcement function (resource control execute Funct1n, abbreviated as RCEF), responsible for enforcing policy received; border gateway function (border GatewayFunct1n, referred to as BGF), is responsible for policy enforcement and port address translation; basic transmission function (base transport Funct1n, abbreviated as BTF), the data transmission node; application service function (Applicat1n Funct1n, referred to as AF), for providing a specific service application , for example, multimedia system (IMS) and the like; network attachment subsystem (NetworkAttachment subsystem, the NASS for short), is responsible for providing information about the user subscription data.

[0005] 图2为ITU定义的RACF的详细框架,RACF由两部分组成,分别是策略决策功能实体(Policy Decis1n Funct1nal Entity,简称为F1D-FE)和传输资源控制功能实体(Transport Resource ControlFunct1nal Entity,TRC-FE),其中,TRC-FE 通过Re与传输功能交互,通过Rn与传输资源执行功能实体(Transport ResourceEnforcementFunct1nal Entity,简称为TRE-FE)交互,并且,PD-FE通过Rt与TRC-FE交互,通过Rh与用户驻地网(Customer PremisesNetwork,简称为CPN)交互,通过Rw与策略执行功能实体(Po I i cyEnf or cement Funct1nal Entity,简称为PE-FE)交互,通过Rs 与业务层的业务控制功能(Service Control Funct1ns,简称为SCF)交互,通过Ru与网络附着控制功能(Network Attachment ControlFunct1ns,简称为NACF)交互,并且F1D-FE 通过Ri 接口与其他下一代网络交互。 [0005] FIG. 2 is a detailed framework for RACF defined by ITU, RACF consists of two parts, namely a policy decision functional entity (Policy Decis1n Funct1nal Entity, referred to as F1D-FE) and the transmission resource control functional entity (Transport Resource ControlFunct1nal Entity, TRC-FE), wherein, TRC-FE by Re function interacts with the transmission, through Rn transmission resource enforcement function (transport ResourceEnforcementFunct1nal entity, referred to as TRE-FE) interact, and, PD-FE by Rt interacting with TRC-FE , Rh and by CPN (Customer PremisesNetwork, abbreviated as CPN) interacts, by the policy enforcement function Rw (Po I i cyEnf or cement Funct1nal entity, referred to as PE-FE) interact with the service by the service layer control Rs function (Service control Funct1ns, abbreviated to SCF) interact through a network attachment control function and Ru (network attachment ControlFunct1ns, simply referred to as the NACF) interaction, and F1D-FE Ri through the interface to interact with other next generation network.

[0006] 在某些特定的条件下,例如,固定用户按需点播带宽,申请一个小时的快速文件上传功能,从用户点播的时候开始,运营商将为用户执行不同的资源接纳控制策略、采取不同的计费方式。 [0006] Under certain conditions, for example, fixed users on-demand bandwidth applications an hour fast file upload function, starting from the time requested by the user, the operator will execute a different user resource and admission control strategy, taking different billing. 这种新的资源接纳控制策略和计费方式在用户点播的一个小时后失效,目前,当时间到达时用户需要通过再次主动请求结束带宽点播来调整自己的资源接纳控制策略、计费方式,即一次完整的带宽按需点播需要用户连续的两次请求才能完成,否则,网络侧不会调整该用户的资源接纳控制策略和计费方式,从而降低了用户体验。 This new resource admission control policy and charging mode after an hour-demand user failure, at present, when the time arrives to user needs by the end of the bandwidth-on-demand initiative to request again to adjust their resource and admission control policy, billing, that is, a complete on-demand bandwidth required two consecutive user requests to complete, otherwise, the network side does not adjust the user's resource admission control policy and charging mode, which reduces the user experience.

[0030] 图5为根据本发明实施例一的资源接纳控制执行功能实体20的结构示意图,资源接纳控制执行功能实体20包括:接收模块200、解析模块202、重验证事件触发器204和发送模块206。 [0030] FIG. 5 is a schematic structural diagram of a resource admission control entity 20 performs functions according to the embodiment of the present invention, the resource admission control entity 20 performs functions comprising: a receiving module 200, a parsing module 202, event trigger reauthentication 204 and a sending module 206. 其中,接收模块200,用于接收资源接纳控制决策功能实体10下发的业务策略;解析模块202,用于从上述业务策略中解析出重验证时间参数;重验证事件触发器204,用于在重验证时间参数指示的时间到达时,触发发送模块206 ;发送模块206,用于向资源接纳控制决策功能实体10发送策略请求,请求资源接纳控制决策功能实体10更新上述业务策略。 Wherein, the receiving module 200, configured to receive a resource admission control decision function entity 10 delivers the service policy; parsing module 202 for parsing reauthentication time parameter from the service policy; reauthentication event trigger 204, for when the time indicated by the parameter re-authentication time is reached, it triggers the transmission module 206; a transmission module 206 for receiving the control 10 transmits a request policy decision function entity to a resource request the resource admission control decision function entity 10 updates the business strategy.

[0031] 通过本发明实施例的上述资源接纳控制执行功能实体20,可以在重验证时间参数指示的时间到达时主动请求资源接纳控制决策功能实体10更新业务策略,而无需由用户发送请求触发,从而提高了用户体验。 [0031] The resources the embodiments of the present invention, admission control enforcement function 20, can actively request resource admission control decision function entity 10 updates the service policy at reauthentication time parameter indicates the time to reach, without the user sends a request trigger, thereby improving the user experience.

[0032] 在实际应用中,如果采用TOLL模式,则资源接纳控制执行功能实体20的接收模块200还可以用于接收用户业务的资源预留指示,其中,该资源预留指示中携带有该用户业务的有效时长;发送模块206还用于向资源接纳控制决策功能实体10发送请求,请求资源接纳控制决策功能实体10为该用户业务提供资源预留,其中,该请求中携带有上述有效时长,以使资源接纳控制决策功能实体10可以根据该有效时长确定上述重验证时间参数。 [0032] In practice, if TOLL mode, the resource admission control enforcement function 200 of the receiving module 20 may also be configured to receive resource reservation indication user traffic, wherein the resource reservation indication to the user carries when the effective length of service; sending module 206 is further configured to a resource admission control decision function entity 10 sends a request, the request resource and admission control decision function entity 10 for the user service providing resource reservation, wherein the request carries the effective duration, so that the resource admission control decision function entity 10 may determine the above-described long-time reauthentication when the valid parameters.

[0033] 图6为根据本发明实施例一的资源接纳控制系统的策略交互方法的流程图,该方法包括(步骤S602-步骤S606): [0033] FIG 6 is a flowchart of an embodiment of a method of interaction policies RACS embodiment of the present invention, the method comprises (Step S602- step S606):

[0034] 步骤S602,资源接纳控制执行功能实体20接收资源接纳控制决策功能实体10下发的业务策略; [0034] step S602, the resource and admission control function 20 performs resource admission control decision function receiving entity delivers the service policy 10;

[0035] 其中,资源接纳控制决策功能实体10制定的业务策略可以是以I3USH模式制定的,也可以是I3ULL模式制定的。 [0035] where the resource and admission control business policy decision function entity 10 can be developed based on I3USH pattern making, it can also be I3ULL pattern developed. 以I3USH模式为例,用户终端向应用功能实体30发送业务请求,应用功能实体30在接收到业务请求后,请求资源接纳控制决策功能实体10为相关的业务提供资源预留,其中,该业务请求中携带有所请求的业务的有效时长,资源接纳控制决策功能实体10根据该有效时长,可以确定重验证时间参数,并将该重验证时间参数携带在业务策略中下发给资源接纳控制执行功能实体20。 In I3USH mode as an example, the application function entity to the user terminal 30 sends a service request, the application function entity 30 upon receiving a service request, the request resource and admission control decision entity 10 provides functions related to resource reservation for the service, wherein the service request the duration that the requested service has been carried in, the resource admission control decision function entity 10 according to this effective length can be determined reauthentication time parameter, and the reauthentication time parameter is carried in the service policy resource admission control functions performed entity 20. 例如,如果用户终端在网络时间9:00发送业务请求,其中有效时长为I个小时,则重验证时间参数可以为网络时间10:00。 For example, if the user terminal sends a service request in the network at 9:00, which is the effective length of I hour, the time parameter may be a reauthentication network 10:00.

[0036] 步骤S604,资源接纳控制执行功能实体20从上述业务策略中解析出重验证时间参数; [0036] step S604, the resource and admission control parameters to perform reauthentication time from the parsed service policy entity 20 functions;
