Description

一种对承载进行处理的方法
技术领域
本发明涉及移动通信技术,特別是涉及一种对承载进行处理的方法。 发明背景
目前, 随着 IP业务的不断发展, 如何对 IP业务进行准确合理的计 费以及其他业务处理, 已成为运用商普遍关注的问题。
对于一个 IP业务而言, 如果 IP网络能够提供多种业务, 如电子邮 件(Email )收发业务、基于无线应用协议的( WAP, Wireless Application Protocol ) 的浏览业务、 以及基于文件传输协议 ( FTP , File Transfer Protocol )的文件传输等业务,则终端可以基于一个激活的分组数据协议 上下文( PDP Context, Packet Data Protocol Context )进行多种业务, 这 样,终端的分组数据流中包括多个 IP数据流。为了针对终端的分组数据 流中包括多个 IP数据流的情况进行准确合理的计费处理,第三代合作伙 伴计划 ( 3GPP, The 3rd Generation Partnership Project )提出了基于业务 数据流的计费(FBC, Flow Based Charging )α 基于业务数据流的计费可 被认为是通过一些类似筛子的过滤器将同一 PDP Context中承载的不同 业务的 IP数据流分别筛选出来, 然后针对不同过滤器过滤出的 IP数据 流进行分别计费。 可见, 基于业务数据流的计费与传统的基于 PDP Context的计费相比,基于业务数据流的计费能够为运营商或业务提供者 提供更为丰富的计费手段。
在基于业务数据流的计费处理中,3GPP定义了基于业务数据流计费 的计费规则功能( CRF, Service Data Flow Based Charging Rule Function ) 实体和传输面功能(TPF, Traffic Plane Function ) 实体。 图 1是在现有 技术中基于业务数据流的计费处理的流程图。 参见图 1 , 现有技术主要 是利用 CRF实体和 TPF实体来实现基于业务数据流的计费处理, 其具 体实现过程包括:
步驟 101 : TPF实体将计费规则请求发送至 CR 实体。
这里, TPF实体可以是在承载建立时, 或承载修改时, 或检测到触 发事件时, 执行本步骤的过程。 其中, 触发事件可以是由 CRF实体提供 给 TPF实体的, 比如, 业务服务质量参数变化等。
另外, TPF实体发送至 CRF实.体的计费规则请求中携带有供 CRF 实体确定计费规则的输入信息, 该输入信息包括与终端相关的信息、 承 载特性以及与网络相关的信息等。
步骤 102: CRF实体根据计费规则请求选择计费规则。
步骤 103: CRF实体将所选的计费规则发送至 TPF实体。
这里, CRF实体发送至 TPF实体的计费规则中携带计费机制、 计费 类型、 计费键、 业务数据流过滤器和计费规则优先级等信息。
步骤 104: TPF实体根据接收到的计费规则对当前承载中的 IP流进 行过滤, 并对过滤出的各 IP流进行基于业务数据流的计费处理。
从上述图 1所示流程可以看出, 在利用 CRF实体和 TPF实体来实 现基于业务数据流的计费处理中, CRF实体是控制实体, 而 TPF实体仅 仅作为一个执行实体, 被动地根据 CRF实体下发的指示进行相应操作, TPF实体无法参与承载的计费控制。这样, 当 IP网络升级成能够支持基 于业务数据流计费处理的网络时, 对于任意一条承载的建立, 均会导致 TPF实体与 CRF实体进行交互, 并由 CRF实体对相应承载进行计费控 制。 然而, 在实际应用中, 当网络升级成能够支持基于业务数据流计费 处理的网络时, 在业务部属初期, 由于引入新特性会对现有网络产生较 大的冲击, 因此, 为了减少引入的基于业务数据流的计费处理特性对现 有网络的冲击, 运营商可能只部署一部分业务基于业务数据流进行计 费, 其他业务保持原有的计费方式不变。 比如, 运营商向用户提供了流 媒体业务和网页浏览业务, 只在流媒体业务中根据不同流媒体内容进行 区分计费, 对于网页浏览业务则无需根据浏览的网页内容进行区分计 费, 而是统一按照固定的计费模式进行计费。 这样, 当网络升级成能够 支持基于业务数据流计费处理的网络时,现有技术中, 完全由 CRF控制 的、 对 TPF中的所有承载采用基于业务数据流的计费方式, 则无法满足 实际网络演进的需要, 并且会导致 CRF实体与 TPF实体之间生成大量 的冗余消息, 极大地降低了网络的性能。 发明内容
本发明的主要目的是提出一种对承载进行处理的方法, 有效避免基 于业务数据流的控制功能实体与 TPF实体之间冗余消息的生成,符合实 际网络演进的需要。
为达到上述目的, 本发明的技术方案是这样实现的:
一种对承载进行处理的方法, 该方法包括:
A、 设置处理条件以及对应于处理条件的处理方式;
B、 传输面功能实体监测到承载事件发生, 判断当前的承载信息与 所设置的处理条件是否相匹配, 如果是, 则执行步骤 C, 否则, 执行步 骤 D;
C、 传输面功能实体才艮据匹配到的处理条件所对应的处理方式对当 前承载进行处理, 结束当前流程;
D、 传输面功能实体对当前承载进行基于业务数据流的处理。
所述步骤 A包括: 根据实际业务需求, 将处理条件及对应于处理条 件的处理方式直接设置在传输面功能实体中。 所述步骤 A包括: 基于业务数据流的控制功能实体将处理条件及对 应于处理条件的处理方式发送至传输面功能实体, 传输面功能实体将接 收到的处理条件及对应于处理条件的处理方式设置在自身中。
在步骤 A中, 所述基于业务数据流的控制功能实体将处理条件及对 应于处理条件的处理方式发送至传输面功能实体的步骤包括: 在网络初 始升级成支持基于业务数据流的计费 FBC特性的网络时,基于业务数据 输面功能实体。 ,
所述步骤 A进一步包括: 在处理条件或处理方式发生变化时, 基于 业务数据流的控制功能实体将变化后的处理条件及对应于处理条件的 处理方式发送至传输面功能实体; 所述传输面功能实体根据当前接收到 的变化后的处理条件及对应的处理方式进行更新设置。
所述处理条件为可标识出特定承载的承载信息。
所述处理条件为指定的接入点名称和 /或指定的 IP五元组。
在步骤 B中, 所述承载事件为承载建立; 或承载修改; 或承载删除。 所述处理方式为通用承载计费方式。
所述通用承载计费方式包括: 通用分组无线业务 GPRS通用承载计 费方式, 和 /或数据业务通用承载计费方式。
所述处理方式为通用承载业务服务盾量控制方式。
所述通用承载业务服务质量控制方式包括: GPRS 通用承载业务服 务质量控制方式, 和 /或数据业务通用承载业务服务质量控制方式。
所述步骤 A进一步包括: 设置处理条件对应的优先级;
在步骤 B中, 所述判断当前的承载信息与所设置的处理条件是否相 匹配的步骤包括: 传输面功能实体按照对应于处理条件的优先级顺序, 将当前的承载信息与所设置的处理条件依次进行匹配及判断是否相匹 配。
一种对承载进行处理的方法, 该方法包括:
a、设置第一类接入点名称对应基于业务数据流的计费处理, 并设置 第二类接入点名称对应基于通用承载的计费处理;
b、传输面功能实体监测到承载事件发生, 判断当前承载的接入点名 称属于第一类接入点名称还是第二类接入点名称, 如果是第一类接入点 名称, 则执行步骤 C, 如果是第二类接入点名称, 则执行步骤 D;
c、 传输面功能实体基于业务数据流的计费处理对当前承载进行计 费, 结束当前流程;
d、 传输面功能实体基于通用承载的计费处理对当前承载进行计费。 由此可见, 本发明设置了可标识特定承载的处理条件及对应于处理 条件的处理方式, TPF实体能够根据所设置的该处理条件及对应于处理 条件的处理方式, 直接对指定承载进行基于业务数据流计费处理或是基 于通用承载计费处理, 当采用基于业务数据流的计费处理时, TPF实体 向基于业务数据流的控制功能实体请求计费规则, 并根据基于业务数据 流的控制功能实体的指示进行相应的计费处理; 当采用基于通用承载的 计费处理时, TPF实体基于每承载进行计费处理,无需同 CRF进行交互。 从而实现了对 TPF实体中的部分承载应用基于业务数据流的计费处理, 其余部分则进行现有的基于通用承载的计费处理, 减少了基于业务数据 流的控制功能实体和 TPF实体之间的消息交互,有效避免了基于业务数 据流的控制功能实体与 TPF实体之间冗余消息的生成,并降低了新增特 性对现有网络的影响, 符合实际网络演进的需要。 附图简要说明
图 1是在现有技术中基于业务数据流的计费处理的流程图。 图 2是在本发明实施例中对承载进行处理的流程图。 实施本发明的方式
本发明的核心思想是: 在 TPF实体中设置处理条件以及对应于处理 条件的处理方式; TPF实体监测到承载事件发生, 判断当前的承载信息 与所设置的处理条件是否相匹配, 如果是, 则根据匹配到的处理条件所 对应的处理方式对当前承载进行基于承载的处理, 否则, 对当前承载进 行基于业务数据流的处理。
为使本发明的目的、 技术方案和优点表达得更加清楚明白, 下面结 合附图及具体实施例对本发明再作进一步详细的说明。
图 2是在本发明实施例中对承载进行处理的流程图。 参见图 2, 本 发明实现对承载进行处理的过程包括以下步骤:
步驟 201: 设置处理条件及对应于处理条件的处理方式。
这里, 所述的处理条件为可标识出承载的相关信息, 比如指定的接 入点名称(APN )和 /或指定的 IP五元组等。 其中, 所述的 IP五元组包 括: 源 /目的 IP地址、 源 /目的端口号、 协议标识等信息。
在本步骤中, 所述的处理方式为对 于处理条件中指定业务的处理 方式, 比如, GPRS通用承载计费方式, 即基于每个 PDP上下文进行统 计的计费方式; 和 /或, 数据业务通用承载计费方式等。
在本步骤中, 所述设置的具体实现过程为: 方式一、 由运营商根据 网络的实际业务需求, 将处理条件及对应于处理条件的处理方式直接设 置在 TPF实体中; 方式二、 由基于业务数据流的控制功能实体将处理条 件及对应于处理条件的处理方式发送至 TPF实体, TPF实体将接收到的 处理条件及对应于处理条件的处理方式设置在自身中。 此处以及以下所 述的基于业务数据流的控制功能实体可以是现有的 CKF 实体或现有的 CRF实体进行功能增强后的实体。
其中, 在采用方式二时, 基于业务数据流的控制功能实体可在特定 时刻执行所述的发送过程, 如在网络初始升级成支持 FBC特性的网络 时, 由基于业务数据流的控制功能实体将处理条件及对应于处理条件的 处理方式发送至 TPF实体; 又如在处理条件或处理方式发生变化时, 基 于业务数据流的控制功能实体将变化后的处理条件及对应于处理条件 的处理方式发送至 TPF实体, TPF实体根据当前接收到的变化后的处理 条件及对应的处理方式进行更新设置。 .
另外,为了确保在一个承载信息可同时匹配多个处理条件的情况下, 能够按照指定处理方式优先对承载进行处理, 在本步骤中, 还可以设置 对应于处理条件的优先级, 该设置对应于处理条件的优先级的具体实现 过程也可以采用上述的方式一和方式二来实现。
比如, 本步骤中所设置的处理条件以及对应于处理条件的处理方式 和优先级可为如下表 1所示的形式。

表 1
步骤 202: TPF实体监测到承载事件发生。
这里, 所述的承载事件发生包括: 承载建立, 比如 TPF实体接收到 承载建立请求; 或承载修改; 或承载删除等事件发生。
步骤 203: TPF 实体判断当前的承载信息与所设置的处理条件是否 相匹配, 如果是, 则执行步骤 204, 否则, 执行步骤 205。
这里, 所述的承载信息可以为当前承载的 APN信息, 和 /或 IP五元 组信息等。
需要说明的是, 如果在步骤 201中, 设置了对应于处理条件的优先 级, 则在本步珮中, TPF实体按照对应于处理条件的优先级顺序, 将当 前的承载信息与所设置的处理条件依次进行匹配, 也就是说, TPF实体 首先将当前的承载信息与所设置的优先级最高的处理条件进行匹配, 如 果两者不匹配, 再将当前的承载信息与所设置的优先级次高的处理条件 进行匹配, 依此类推, 直至匹配成功或失败。
步骤 204: TPF实体根据匹配到的处理条件所对应的处理方式对所 述承载进行基于承载的处理, 结束当前流程。
需要说明的是, 如果在步骤 203中, TPF实体按照对应于处理条件 的优先级顺序进行匹配, 那么在本步骤中, TPF实体则按照对应于匹配 到的优先级最高的处理条件的处理方式, 对所述承载进行相应的处理。
比如, 在步骤 201中, 预先所设置的处理条件以及对应于处理条件 的处理方式和优先级为如下表 2示的形式。
优先级 处理条件 处理方式
1 APN="ABC,, 处理方式 1 : 按照原有 GPRS 方式基于每个 PDP 上下文进行统 计, 采用访问企业私有 APN 为 "ABC"的费率进行计费

3 APN="cmwap" 处理方式 3: 按照原有 GPRS 方式基于每个 PDP 上下文进行统 计,采用访问 WAP数据业务的费率 进行计费
4 源 IP=通配, 处理方式 4: 对满足相应 IP五 源端口 =通配 元组的数据包进行统计, 使用 FTP 目的 IP=129.0.0.1 , 业务的费率进行计费 的端口 =80
源 IP=129.0.0.1 ,
源端口 =80
目的 IP=通配,
目的端口 =通配
表 2
参见表 2, 上述步驟 203至步骤 204的具体实现过程可以举例为: TPF 实体根据设置的处理条件的优先级, 依次判断建立的承载的 APN 是否为 "ABC"、 或 "cnmet"、 或 "cmwap" , 如果该承载的 APN与上述 设置的一个 APN相匹配, 则 TPF按照对应于匹配到的处理条件的处理 方式, 对该承载进行处理, 例如, 建立承载的 APN为 "cmnet" , 则 TPF 采用处理方式 2对该承载进行处理,即按照原有 GPRS方式基于每个 PDP 上下文进行统计, 采用访问互联网 (Internet )数据业务的费率对该承载 进行处理; 如果该承载的 APN无法与上述设置的一个 APN相匹配, 则 TPF继续判断该承载的 IP五元组是否满足 "源 IP=通配, 源端口 =通配, 目的 IP-129.0.0.1 , 目的端口 =80"、 或 "源 IP = 129.0.0.1 , 源 port =80, 目的 IP=通配, 目的端口=通配" 的条件, 如果满足, 则 TPF采用处理 方式 4对该承载进行处理, 即对满足该 IP五元组的数据包进行统计,使 用 FTP业务的费率对该承载进行处理。
步骤 205: TPF实体对所述承载进行基于业务数据流的处理。
这里, 本步骤的具体实现过程为现有技术, 参见图 1所示的流程, 可简单描述为: TPF实体将计费规则请求发送至基于业务数据流的控制 功能实体; 基于业务数据流的控制功能实体根据计费规则请求选择计费 规则;基于业务数据流的控制功能实体将所选的计费规则发送至 TPF实 体; TPF实体才 ^据接收到的计费规则对当前承载中的 IP流进行过滤, 并 对过滤出的 IP数据流进行分别计费处理。
需要说明的是, 在上述图 2所示的过程中, 本发明所设置并由 TPF 实体执行的处理方式主要是对承载如何进行计费的处理方式。 在本发明 的其它实施例中, 也可将处理方式设置为计费处理之外的其它处理方 式, 如通用承载业务服务质量(QoS )控制方式, 包括基于业务数据的 QoS控制处理和 /或基于通用承载的 QoS控制处理, 这样, 在后续过程 中, TPF实体在匹配成功后, 直接按照对应于所匹配到的处理条件的处 理方式, 对当前承载进行计费处理之外的其它处理。
以上所述, 仅为本发明的较佳实施例而已 , 并非用于限定本发明的 保护范围。 凡在本发明的精神和原则之内, 所作的任何修改、等同替换、 改进等, 均应包含在本发明的保护范围之内。
