Description

一种计费方法、控制面网元、转发面网元和计费系统 技术领域
本发明涉及通信技术领域，尤其涉及一种计费方法、控制面网元、转发面网元和计费系统。
背景技术
计费是运营商为了衡量用户对网络资源的占用情况，根据一定的资费政策建立的费用计算系统。演进的分组核心网(Evolved Packet Core，简称：EPC)的分组交换网络支持第三代伙伴计划(The 3rd Generation Partnership Project，简称：3GPP)定义的两种计费系统：在线计费系统(Online Charging System，简称：OCS)和离线计费系统(Offline Charging System，简称：OFCS)。在线计费通过Gy接口与OCS交互实现；离线计费通过Ga接口与CG交互实现。计费系统根据采集的计费信息进行用户账单的生成及用户费率的结算。
控制和转发分离是网关架构设计中最基本的设计思想。将网关的功能拆分为两大部分：网关控制器(Gateway-Controller Plane，简称：GW-C)和网关用户面(Gateway-User Plane，简称：GW-U)，分别对应网关的控制面和转发面。GW-C主要负责用户接入、策略控制和计费话单管理；GW-U主要负责对数据进行转发，并执行控制面下发的控制和计费策略。计费系统读取话单中的用户对网络资源使用的统计信息，实现计费的功能。
目前公开的计费方法(以离线计费、转发面触发的转发面计费统计信息上报流程为例)主要包括以下步骤：
1、GW-C向GW-U下发计费规则，携带计费上下文标识参数。
所述计费规则，是计费的依据，为GW-C从策略和计费规则实体(Policy and Charging Rules Function，简称：PCRF)获取，或者是从charging characteristics根据配置映射获取的。
所述计费上下文标识参数，可以是业务流标识，如UE IP，或业务流的IP五元组，或具有某种报文头特征的标识。
2、当GW-U触发条件发生时，如Time/Volume/Service阈值到达时，GW-U 向GW-C发送转发面计费统计信息和计费上下文标识。
3、GW-C根据计费上下文标识，进行转发面计费统计信息与转发面状态信息的关联，并生成话单。
4、GW-C将话单发送给计费系统。
现有技术中的转发面计费统计信息的上报路径为：GW-U→GW-C→计费系统，路径较长，转发面计费统计信息传输时延较大，使得计费时延较大。
发明内容
本发明提供了一种计费方法、控制面网元、转发面网元和计费系统，实现转发面计费统计信息的上报直接由转发面网元发送到计费系统，可以缩短计费时延。
本发明第一方面提供了一种计费方法，转发面网元先执行计费统计，再向计费系统发送转发面计费统计信息，计费系统基于所述转发面计费统计信息及控制面计费信息执行计费处理。
在该技术方案中，通过增加转发面网元与计费系统之间的接口，实现转发面计费统计信息的上报直接由转发面网元发送到计费系统，从而缩短了计费时延。
计费系统包括离线计费系统或者在线计费系统；计费处理可以包括离线计费话单生成或者在线计费配额授权；其中，离线计费话单生成由离线计费系统完成，在线计费配额授权由在线计费系统处理。
转发面网元可以基于计费规则执行计费统计。其中，所述计费规则是计费的依据，可以是计费系统从控制面网元，或者，从charging characteristics根据配置映射获取的，再发送给转发面网元的；当然，也可以由控制面网元通过控制面网元与转发面网元之间的接口下发。
转发面计费统计信息包括转发面计费统计信息，所述转发面计费统计信息是转发面网元根据用户对网络资源使用的测量信息；
可选的，转发面网元还向计费系统发送计费上下文标识，所述计费上下文标识可以是业务流标识、业务流的IP信息以及与待计费的一个或多个业务流相关联的计费组或费率标识中的至少一种。
若所述计费系统为在线计费系统，所述转发面计费统计信息为配额请求信息，所述配额请求信息用于向在线计费系统申请新的配额。
控制面计费信息可以理解为控制面网元的状态信息，如QoS信息、用户位置信息、业务策略与计费控制信息等；若所述计费系统为在线计费系统，所述控制面计费信息还可以理解为重新授权请求的信息。
在一种可选的实施方式中，所述转发面计费统计信息是所述转发面网元在转发面计费统计信息满足预设计费触发条件时发送的。
若计费系统为离线计费系统，所述预设计费触发条件可以包括转发面计费统计信息达到Time门限、或Volume门限，或达费率点切换时刻；
若计费系统为在线计费系统，所述预设计费条件可以包括配额耗尽、达到配额有效时长或达到配额空闲时长等等。且若计费系统为在线计费系统，所述转发面计费统计信息用于向在线计费系统申请新的配额，此时，所述转发面计费统计信息可以采用Diameter协议的信用控制请求消息来实现。
