Description

在线计费方法 ^^置 技术领域 本发明涉及通信领域, 具体而言, 涉及一种在线计费方法及装置。 背景技术 在第三代合作伙伴计戈1 K 3rd Generation Partnership Project,简称为 3GPP ) 通信标准组织中定义了相关的计费系统和计费信息传送的方法。 居通信的 计费实时性区分为后付费的离线计费方式和预付费的在线计费方式。 图 1是根据相关技术中的在线计费逻辑示意图, 如图 1所示, 在线计费 方式的信用控制请求 /响应消息 ( Credit Control Request/ Credit Control Answer, 简称为 CCR/CCA ) 是通过内嵌在网元的计费触发功能 ( Charging Trigger Function, 简称为 CTF ) 遵循 Diameter十办议通过 R。接口与在线计费 系统 ( Online Charging System, 简称为 OCS )进行实时交互的。 图 1中的网 元 ( Network Element, 简称为 NE ) 内部可以内嵌策略和计费执行功能实体 ( Policy and Charging Enforcement Function, 简称为 PCEF ) 也可以不内嵌。 内嵌 PCEF就是本发明所针对的部署策略和计费控制 ( Policy and Charging Control , 简称为 PCC ) 的情况。 随着通信的发展, 在动态数据用量方面, 存在一种由第三方支付用户业 务流量的应用场景, 例如, 用户从网上书店下载已购买的电子书, 或者用户 从运营商购买和下载游戏, 或者用户浏览网上电影以决定是否购买整部电影 等。在这些场景中,运营商或第三方控制的业务提供者支付用户使用的用量。 因此,通过对策略和计费控制( Policy and Charging Control,简称为 PCC ) 架构的增强来实现上述事务 IP业务的策略控制, 例如, 从用户的用量中扣除 业务提供商或运营商授权的数据用量等。 图 2是根据相关技术中的顺应运营 商和第三方业务提供商的业务使用场景增强的 PCC的流程图, 如图 2所示, 包括如下的步骤: 步骤 S201 , 用户设备( User Equipment , 简称为 UE )附着到演进的分组 域系统 ( Evolved Packet System , 简称为 EPS ) 网络上, 即, UE附着到分组 数据网络网关 ( Packet Data Network Gateway , 简称为 P-GW ) 上。 步骤 S202 , P-GW与策略和计费规则功能实体( Policy and Charging Rules Function, 简称为 PCRF ) 进行网络协议连接访问网络 ( Internet Protocol Connectivity Access Network, 简称为 IP-CAN )会话建立。 步骤 S203 , UE向应用功能实体 ( Application Function, 简称为 AF ) 尝 试访问由运营商或第三方业务提供商提供的业务, 即, UE连接到业务提供 商请求业务。 步骤 S204, AF被触发为用户建立允许的动态数据用量连接, 这种触发 可以基于不同的应用场景, 例如, 用户买电子书, 第三方业务提供商提供一 段免费的流量下载给用户预览电子书的内容等。 步骤 S205 , AF通过 Rx接口下发业务数据流信息和对应的允许用户设 备免费使用的信息(例如,允许的流量信息( Volume allowance )等)给 PCRF。 步骤 S206, PCRF向 AF返回确认 ( Acknowledgement, 简称为 Ack )响 应消息。 步骤 S207 , PCRF进行计费规则分发。 步骤 S208 , PCRF通过 Gx接口向 P-GW提供计费规则 ( rule )及对应的 允许用户设备免费使用的信息 (allowances )和事件触发 ( Event trigger )等。 步骤 S209, P-GW内嵌策略和计费执行功能实体 ( Policy and Charging Enforcement Function, 简称为 PCEF ) 安装执行计费规则。 步骤 S210, P-GW响应 PCRF, 向 PCRF发送响应消息 Ack。 步骤 S211 , 用户设备收到想要的业务。 对以上描述的应用场景拓展开去不排除另一种第三方支付用户部分用量 的应用场景, 即, 用户从运营商购买和下载游戏, 或者用户浏览网上电影以 决定是否购买整部电影等场景中, 运营商或第三方控制的业务提供者支付部 分用户使用的用量, 并告知运营商他们为用户提供使用其它资费的大约多少 用量。 针对相关技术中在第三方业务提供商或运营商允许用户以其它资费或免 费使用一定的业务的场景中如何实现在线计费的问题, 目前尚未提出有效的 解决方案。 发明内容 本发明的主要目的在于提供一种在线计费方法及装置, 以至少解决上述 问题。 根据本发明的一个方面, 提供了一种在线计费方法, 包括: 当用户设备 被允许以原资费以外的其它资费和

S402 , P-GW与 PCRF进行 IP-CAN会话建立。 步骤 S403 , UE向 AF尝试访问由运营商或第三方业务提供商提供的电 子书下载业务, 即, UE连接到业务提供商请求业务。 步骤 S404, 第三方业务提供商的 AF被触发为用户建立允许的动态数据 用量连接, 这种触发可以基于不同的应用场景, 这里是: 用户已经购买电子 书, 第三方业务提供商提供一定的业务允许给用户, 可以是允许的流量或时 长等信息, 这里不做限定, 此实施例以允许的流量信息为例提供免费的流量 下载 ( Volume Allowance ) 给用户下载已经购买的电子书。 步骤 S405 , AF通过 Rx接口下发业务数据流信息和对应的允许用户设 备免费使用的信息 (即, 上述的一定用量的信息在该实施例中是允许的流量 信息 Volume Allowance ) 和计费建议信息 ( Advice of Charging ) 给 PCRF。 需要说明的是, 这里的计费建议信息可以是 0%表示建议承载侧对这段用量 釆用原来资费的 0%进行计费, 因为用户已经在第三方付费购买了电子书, 第三方对这部分用量下载已经收过费用, 不建议运营商的承载侧再次收费。 当然对于计费建议信息的具体格式和值定义, 这里只是示例, 不作限定。 步 4聚 S406 , PCRF向 AF返回 Ack响应消息。 步骤

OCS的信用控制请求 CCR中携 带对应所述业务的允许的流量信息 Volume Allowance和相关计费建议信息 等。 步骤 S411 , —旦 OCS发现接收到的 CCR中含有流量信息 Volume Allowance和对应的计费建议信息(例如, 这里为 0%表示建议承载侧对这段 用量釆用原来资费的 0%进行计费), 就根据计费建议的资费计算费用并从用 户账户预扣金额 (根据本例的情况是不对用户的账户进行预扣;)。 步骤 S412 , OCS返回 CCA消息给 P-GW, 使用户在不消耗自身账户费 用的前提下获取免费的对应流量的业务。 步骤 S413 , 在允许的流量执行完后, P-GW开始与 OCS的如同现有技 术的在线计费信用控制, 此时的 CCR中不再携带允许用户设备免费使用的 流量信息 Volume Allowance和对应的计费建议信息或者携带这两个字段, 但 取值都为 0, 本发明对实现的具体方式不作限定。 同时, 在上述过程中, OCS还可以与 AF进行实时信用控制。 图 5是根据本发明实施例的针对动态数据用量增强策略提出的应用侧在 线计费消息的流程示意图, 如图 5所示, 包括如下的步骤: 步骤 S501 , UE附着到网络, 并尝试访问由运营商或第三方业务提供商 提供的业务, AF被触发为用户建立允许的免费或其它资费建议的动态数据 用量。 步骤 S502, AF在发送给 OCS的信用控制请求 CCR中包含允许用户设 备以其它资费和 /或免费使用的流量信息 Volume Allowance (即, 上述的一定 用量的信息在该实施例中是通过流量信息来体现的)和相关计费建议信息(例 如, 这里建议承载侧以 0%的资费计费, 也就是说业务侧需要以 100%的资费 计费) 等。 步骤 S503 , OCS执行信用控制, 一旦发现 CCR中存在用量信息和对应 的计费建议, 就才艮据计费建议进行对这部分用量的业务侧信用控制, 例如, 这里对业务侧需要以 100%的资费计费, 本发明对计费建议的具体格式、 取 值和实现方式不作限定。 步骤 S504 , OCS返回信用控制响应消息给内嵌 PCEF的网元。 步骤 S505 , 当这部分用量处理完后, 网元侧与 OCS侧继续按照现有技 术的信用控制交互流程进行, 后续的 CCR中可以不再携带用量和对应的计 费建议这两个字段, 也可以携带这两个字段, 其取值为 0。 本发明对这种实 现可能性不作限定。 实施例二 在用户决定付费购买网上电影之前, 该第三方业务提供商允许该用户免 费浏览一定时间的片花,例如,通过允许一定的时长的片花预览的方式( Time Allowance ), 下面结合图 4对该过程进行详细描述。 图 4是根据本发明实施例的针对动态数据用量增强策略提出的承载侧在 线计费消息的流程示意图, 如图 4所示, 假定该实施例以使用的是 EPC核心 网为例, 具体计费信息的产生过程包括如下的步骤: 步骤 S401 , UE附着到 EPS网络上, 即, UE附着到 P-GW上。 步骤 S402, P-GW与 PCRF进行 IP-CAN会话建立。 步骤 S403 , UE向
