现有技术中提供了一种针对数据业务的策略机制***， 其架构如图 1 所 示。该***包括策略和计费规则功能装置（ Policy and Charging Rules Function, PCRF ) 11、应用功能（ Application Function )装置 12、订阅信息库（ Subscription Profile Repository, SPR ) 13、 网关 （ Gateway )设备 14和计费装置 15组成。 其中， 计费装置 25可以为在线计费***（Online Charging System, OCS )或 离线计费***（Offline Charging System, OFCS ), 其可以根据网关中的流量 或时长统计对用户进行实时计费。 PCRF可以根据来自订阅信息库 13中的订 阅者信息、 网关设备 14的承载层信息、 PCRF本地配置的一些本地策略， 或 者应用功能装置 12的业务层信息等， 进行业务数据流控制策略决策， 以确定 对该业务数据流的控制策略。 网关设备 14根据上述业务数据流控制策略对业 务数据流进行控制， 从而保证服务质量。
参见图 2, 图 2是现有技术中提供的一种策略控制方法的流程图。
现有技术中的策略控制方法包括：
Al、 PCRF从 SPR接收流量的总使用配额；
A2、 PCRF生成业务数据流控制策略， 在该控制策略中包括监控关键字、 使用信息上报事件触发器， 以及根据流量的总使用配额确定的流量使用门限； A3、 PCRF发送该控制策略给网关设备；
A4、 网关设备根据该控制策略对用户业务的数据流进行策略控制， 并且 对流经该网关的满足该策略的数据流的流量进行累积；
A5、 网关设备在累积值达到该控制策略中所指定的使用门限时， 或者虽 未达到该控制策略中所指定的使用门限， 但满足该策略的数据流中断时， 或 者其他数据流使用信息上报条件时， 网关设备上报所累积的流量信息给
PCRF, 该使用信息中包括监控关键字和流量累积信息；
A6、 PCRF 从上述流量的总使用配额中扣减上报的流量累积信息， 若需 要继续该业务且扣减后的流量总使用配额大于零， 则认为需要向网关设备下 发新的使用配额， 则重复 A2 A5步， 直到最终用户的数据流业务停止， 执行 步骤 A7; 若扣减后的流量总使用配额等于或小于零， 即总使用配额已用完， 则根据运营商策略或用户策略调整业务流的控制策略， 并向网关设备发送新 的数据流控制策略， 直到最终用户的数据流业务停止， 执行步骤 A7。
A7、 业务停止后， PCRF保存剩余的流量总使用配额保存到 SPR中。 发明人在实现本发明的过程中发现， 现有技术中 PCRF可以实现基于流 量累积的策略控制， 但无法实现基于用户的计费相关信息对数据流进行策略 控制， 灵活性较差， 用户的业务体验较差。 发明内容

C6、 策略决策装置接收计费***通过已建立的会话发送的通知消息， 根 据通知消息中携带的已发生的计费相关事件信息生成控制策略。
具体的， 策略决策装置接收到计费***通过会话发送的已发生的第一类 计费相关事件信息后， 更新该第一类计费相关事件的订阅状态， 并基于该已 发生的第一类计费相关事件， 综合其他输入条件生成业务数据流控制策略。
C7、 策略决策装置根据控制策略请求向网关设备发送控制策略。
其中， 步骤 C6和 C7的执行过程可以参考上述第一实施例中步骤 B4和 B5, 在此不再重复描述。 在本发明实施例二提供的策略控制方法实施例中， 策略决策装置获取与 业务信息对应的第一类计费相关事件， 并且向计费***发送订阅第一类计费 相关事件的订阅请求， 以使得计费***在第一类计费相关事件发生时， 向策 略决策装置发送通知消息。 与现有技术相比， 本发明实施例可以在和用户的 业务信息的计费相关事件发生时， 根据该计费相关事情进行策略控制， 使得 用户在进行不同的业务时， 监控不同的计费相关事件， 进而使得策略控制的 灵活性更好。
参见图 5,本发明实施例中根据用户当前的计费相关数据进行策略决策的 方法流程图。
在本发明实施例一或实施例二提供的策略控制方法中， 为了能够基于用 户计费数据为某一业务数据流生成初始控制策略。 策略决策装置还可以执行 以下步骤：
D1、 策略决策装置向计费***发送用户计费数据获取请求。
具体的， 策略决策装置可以在会话请求消息中携带用户计费数据获取请 求， 请求用户计费相关数据。 另外， 策略决策装置还可以在会话建立完成后， 通过该建立的会话向计费***发送用户计费数据获取请求以获取用户当前的 计费相关数据， 然后执行步骤 D2。
D2、 策略决策装置接收计费***返回的用户当前的计费相关数据。
具体的， 策略决策装置接收计费***根据携带在会话请求中的用户计费 数据获取请求或者在会话中发送的用户计费数据获取请求返回的用户当前的 计费相关数据。 用户当前的计费相关数据可以为： 用户当前的账户余额、 用 户一定时期内的流量累积、 用户一定时期内的消费信息、 用户级别和用户套 餐等信息中的一个或多个。
D3、 策略决策装置根据用户当前的计费相关数据生成业务数据流的控制 策略。
具体的， 策略决策装置可以根据用户当前的计费相关数据生成业务数据 流的控制策略， 具体控制策略生成方法可以是策略决策装置根据内置的策略 生成规则综合用户当前的计费相关数据以及其他的输入条件生成业务数据流 控制策略。 例如， 用户当前的计费数据中的话费余额为 10元， 则策略决策装 置在策略生成规则中匹配该条件， 并综合其他条件为该用户的业务数据流决 策出一个对应的 QoS。 D4、 策略决策装置将生成的控制策略发送给网关设备。
本发明实施例中策略决策装置向网关设备发送生成的控制策略。 网关设 备执行该接收到的控制策略对用户的数据业务进行控制。
本发明实施例通过获取用户当前的计费相关数据， 进而根据用户当前的 计费相关数据来生成控制策略， 从而实现基于用户当前帐户或消费状态对用 户的数据业务进行控制。 与现有技术相比， 本发明实施例可以适应更多的应 用场景， 应用范围更广。
进一步的， 本发明实施例中的策略决策装置在接收到用户当前的计费相 关数据后， 可以緩存接收到的计费相关数据， 进而在接收到计费***发送的 通知消息后， 根据通知消息中携带的事件信息更新该緩存的计费相关数据。 本发明实施例可以通过緩存接收到的计费相关数据， 减少策略决策装置与计 费***间的交互次数， 进而减小计费***处理压力， 能较大提升在线计费系 统的实时处理性能。
参见图 6,本发明实施例提供的策略控制方法中根据通知消息中携带的事 件信息发送订阅请求的方法流程图。
本发明实施例一或实施例二提供的策略控制方法中， 在接收到计费*** 发送的通知消息之后， 还可以根据通知消息中携带的事件信息向计费***发 送订阅请求， 该过程主要包括：
El、 策略决策装置根据通知消息中携带的事件信息在预置的计费相关事 件组成的集合中查找以已发生的计费相关事件为前置条件的第三类计费相关 事件。
具体的， 策略决策装置根据通知消息中携带的事件信息在预置的计费相 关事件组成的集合中查找以已发生的计费相关事件为前置条件的计费相关事 件。 在本发明实施例中， 查找到的计费相关事件称为第三类计费相关事件。
E2、 策略决策装置通过已建立的会话向计费***发送订阅第三类计费相 关事件的订阅请求， 以便于计费***在第三类计费相关事件发生时， 向策略 决策装置发送通知消息。
具体的， 策略决策装置通过上述已建立的会话向计费***发送订阅第三 类计费相关事件的订阅请求， 该订阅请求中携带第三类计费相关事件。 计费***在接收到订阅请求后， 监测第三类计费相关事件是否发生， 并 在事件发生时， 向策略决策装置发送通知消息。 策略决策装置在接收到通知 消息后， 根据该通知消息中的事件信息进行策略决策。
需要说明的是， 策略决策装置接收到携带第三类计费相关事件的通知消 息后依然可以根据通知消息中携带的事件信息在预置的计费相关事件组成的 集合中查找以该计费相关事件为前置条件的计费相关事件并进行订阅， 即重 新执行步骤 E1~E2。
本发明实施例中， 根据通知消息中携带的事件信息向计费***发送订阅 请求， 可以适应更多的应用场景， 使用范围较广。 此外， 本发明实施例通过 为事件配置事件类前置条件， 实现了基于特殊前置条件的一类事件进行业务 数据流控制的策略决策， 通过该方法， 可以解决用户在使用数据业务时， 跨 越不同事件域的灵活准确的策略控制， 使得运营商可以进行精准和灵活的业 务数据流精细化控制。
在本发明实施例中， 策略决策装置接收计费***通过上述会话发送的通 知消息可以携带已发生的第一类计费相关事件和 /或第二类计费相关事件。 策 略决策装置在接收到计费***发送的已发生的计费相关事件后， 首先在其所 订阅的第一类计费相关事件中查找， 若查找到， 则说明是第一类计费相关事 件， 更新第一类计费相关事件的订阅状态， 并生成业务数据流控制策略； 若 查找失败， 则在预置的第二类计费相关事件中继续查找， 并在查找成功后， 根据已发生的第二类计费相关事件生成业务数据流控制策略。 通过策略决策 装置支持对第二类计费相关事件的处理能力， 使得策略决策装置无需订阅事 件和维护事件的订阅状态， 可以大幅降低策略决策装置处理订阅和管理订阅 的花费， 降低策略决策装置和计费***的压力， 同时实现了基于计费***丰 富信息的业务数据流精细化控制。
以上从策略决策装置一侧来描述本发明实施例提供的策略控制方法， 下 面从计费***一侧来描述本发明实施例提供的策略控制方法。
参见图 7, 本发明实施例三提供的策略控制方法的流程图。
在本发明实施例三提供的策略控制方法主要包括：
Fl、 计费***接收策略决策装置发送的会话请求消息， 会话请求消息中 携带用户标识。 本发明实施例中的计费***接收策略决策装置发送的会话请求消息， 该 会话请求消息中携带用户标识， 该会话请求消息中还可以携带会话标识。

其中， 应答消息表明策略决策装置和计费***之间的会话建立成功， 应 答消息中可以携带会话标识。
F3、 计费***获取需要监测的计费相关事件。
本发明中的监测指的是计费***能够获知订阅类或非订阅类计费相关事 件的出现， 并能够根据策略决策装置的订阅行为或管理节点的配置在事件发 生后触发向策略决策装置上报所出现的计费相关事件的行为。 需要指出的是, 该监测并不限定在计费***中获知事件的出现和触发上报动作的具体实现方 法。
具体的， 计费***可以通过如下方式获取需要监测的计费相关事件：
1 )计费***接收策略决策装置在会话请求消息或后续在会话中发送的订 阅请求， 该订阅请求中携带策略决策装置需要订阅的计费相关事件。
其中， 策略决策装置在确定需要向计费***订阅的第一类计费相关事件 后， 在会话请求消息或后续在会话中向计费***发送订阅第一类计费相关事 件的订阅请求， 计费***接收该订阅请求。 订阅请求中携带策略决策装置需 要订阅的计费相关事件
2 )计费***在预置的计费相关事件组成的集合中查找与用户标识对应的 计费相关事件。
其中， 计费***可以根据策略决策装置发送的会话请求消息自动在计费 ***预置的计费相关事件组成的集合中查找与用户标识对应的第二类计费相 关事件， 即： 非订阅类事件。 其中， 上述计费相关事件可以预先配置在计费 ***， 计费相关事件的来源不应构成对本发明实施例的限制。
管理节点同时还可以配置该事件的前置条件， 则在查找到第二类计费相 关事件后， 还可以判定当前的用户计费相关数据是否满足该前置条件， 若满 足则确定需要向策略决策装置发送的该计费相关事件。
在本发明实施例中， 与用户标识对应的计费相关事件例如可以为： 该用 户的帐户余额低于某个限额， 该用户的日流量累积达到某个限额等。
需要说明的是， F2和 F3步骤没有严格的先后关系， F3可以在 F2之前执 行。
F4、 计费***监测计费相关事件是否发生， 并在所监测的计费相关事件 发生时通过已建立的会话向策略决策装置发送通知消息， 通知消息用于表明 计费相关事件已发生。
具体的， 计费***监测计费相关事件是否发生， 并在所监测的计费相关 事件发生时， 通过步骤 F2中已建立的会话向策略决策装置发送通知消息， 该 通知消息用于表明计费相关事件已发生， 通知消息中可以携带已发生的某一 个或多个计费相关事件。
策略决策装置接收计费***通过该会话发送的通知消息， 并根据通知消 息中的事件信息进行策略决策， 策略决策装置进行策略决策的详细过程参见 上述方法第一实施例和第二实施例， 在此不再重复描述。
在本发明实施例三提供的策略控制方法中， 计费***在监测到计费相关 事件发生时， 通过建立的会话向策略决策装置发送通知消息， 以便于策略决 策装置结合当前已发生的计费相关事件生成控制策略并下发。 与现有技术相 比， 本发明实施例可以实现基于用户的计费相关信息对数据流进行策略控制 , 计费相关事件的配置、 监测和触发机制灵活， 使得运营商可以根据事件的特 性和运营策略进行灵活的配置， 以小的成本实现业务数据流的精细化控制， 灵活性较好。
参见图 8,本发明实施例提供的策略控制方法中向策略决策装置发送用户 当前的计费相关数据的方法流程图。
在本发明实施例三提供的策略控制方法中， 计费***向策略决策装置发 送用户当前的计费相关数据的过程可以包括：

G2、计费***根据用户计费数据获取请求获取用户当前的计费相关数据。 其中， 计费***中存储有该用户当前的计费相关数据。 用户当前的计费 相关数据例如可以为： 用户当前的账户余额、 用户当前的各种流量累积、 或 用户当前的各种消费累积等。
G3、 计费***向策略决策装置发送用户当前的计费相关数据。
具体的， 若该用户计费数据获取请求包含在会话请求消息中， 则计费系 统在该会话请求消息的应答消息中向策略决策装置发送用户当前的计费相关 数据， 若该用户计费数据获取请求是在会话中发送的， 则计费***在该用户 数据获取请求的应答消息中发送用户当前的计费相关数据。
策略决策装置在接收到用户当前的计费相关数据后， 根据用户当前的计 费相关数据生成控制策略并将生成的控制策略发送给网关设备。 网关设备根 据接收到的控制策略对用户的数据业务进行控制。 策略决策装置根据预置的 策略生成规则、 用户当前的计费相关数据以及其他的输入条件生成控制策略。
本发明实施例通过会话初或会话中获取用户当前的计费相关数据， 并向 策略决策装置发送用户当前的计费相关数据， 使得策略决策装置根据用户当 前的计费相关数据来生成控制策略， 弥补了计费***发送的通知消息仅仅反 映业务使用过程中的用户计费相关数据的变化， 而不能反映业务开始时用户 计费相关数据的历史状态的缺陷， 使得策略决策装置可以基于业务全过程中 完整的用户计费相关数据实时情况进行准确的业务数据流控制。
参见图 9, 本发明实施例四提供的策略控制方法的流程图。
本发明实施例四提供的策略控制方法具体可以包括：
Hl、 计费***接收策略决策装置发送的会话请求消息， 该会话请求消息 中携带用户标识。

H3、 计费***获取需要监测的计费相关事件。
H4、 计费***在计费相关事件发生时， 通过已建立的会话向策略决策装 置发送通知消息， 通知消息用于表明计费相关事件已发生。
其中， 步骤 H1-H4的执行过程和上述第三实施例中步骤 F1-F4相同， 在 此不再重复描述。
H5、 计费***在计费相关事件发生时， 在预置的计费相关事件组成的集 合中查找以该已发生的计费相关事件为前置条件的第四类计费相关事件。 具体的， 计费***在计费相关事件发生时， 在预置的计费相关事件组成 的集合中查找以已发生的计费相关事件为前置条件的计费相关事件。 在本发 明实施例中， 查找到的计费相关事件称为第四类计费相关事件。
需要指出的是， 步骤 H4和步骤 H5之间是时序无关的。
H6、 计费***监测第四类计费相关事件， 在第四类计费相关事件发生时， 通过已建立的会话向策略决策装置发送通知消息。
其中， 通知消息中携带已发生的事件信息， 策略决策装置根据该通知消 息中的事件信息进行策略决策。 策略决策装置进行策略决策的详细过程参见 上述方法第一实施例和第二实施例， 在此不再重复描述。
需要说明的是， 在第四类计费相关事件发生时， 计费***依然可以在预 置的计费相关事件组成的集合中查找以该计费相关事件为前置条件的计费相 关事件并进行订阅， 即重新执行步骤 H5~H6。
在本发明实施例四提供的策略控制方法通过为事件配置事件类前置条 件， 实现了基于特殊前置条件的一类事件进行业务数据流控制的策略决策， 通过该方法， 可以解决用户在使用数据业务时， 跨越不同事件域的灵活准确 的策略控制， 使得运营商可以进行精准和灵活的业务数据流精细化控制。

其中， 新增的管理节点设备根据运营商策略或用户订购信息等定义计费 相关事件、 事件的前置条件、 事件对应的计费***的处理规则和事件对应的 策略决策装置的策略生成规则等， 并对应的将计费相关事件及相关规则发送 到策略决策装置和计费***， 以便于计费***和策略决策装置在计费相关事 件后进行相应的处理。 网关设备可以为通用分组无线服务（General Packet
Radio Service, GPRS ) 网络的网关 GPRS支持节点 （ Gateway GPRS Support
Node, GGSN )、 EPC ( Evolved Packet Core, 演进的核心网） 网络的分组数据 网关 （ Packed Data Network Gateway, PDN-GW ), 或者其它内置策略和计费 执行功能 ( Policy and Charging Execution Function, PCEF )的模块， 网关设备 可以执行策略决策装置发送的控制策略， 进行数据业务的控制。 参见图 10, 本发明实施例五提供的策略控制方法的流程图。
本发明实施例五提供的策略控制方法主要包括：
Sl、 管理节点根据运营商定义和 /或用户订购信息等定义计费相关事件和 相应的处理规则。
具体的， 管理节点接收运营商的配置信息、 用户的订购信息等， 定义用 于用户业务数据流控制的控制策略的事件。 计费相关事件可以为具体指明的 一个累积规则的具体事件， 例如数据业务的消费达到 200元等。 计费相关事 件也可以为不具体的指明一个累积规则的泛化事件， 则具体的累积规则需要 由事件综合其他参数指明， 这个其他参数可以是累积规则标识或累计额等。 例如事件为余额变化， 其他参数可以是余额当前值为 8元。
在本发明实施例中， 在定义事件时还可以定义事件的前置条件， 本发明 中的前置条件指该事件的发生前提， 该前置条件可以是非事件类前置条件， 如：对于指示某一用户数据业务累积达到 100M的事件，其前置条件是激活该 事件时该用户的数据业务累积必须小于 100M; 该前置条件也可以是事件类前 置条件， 即： 另一事件的出现是该事件出现的前提， 如： 对于 "余额高于预 定最低阔值" 事件， 其前置条件可以是另外一个事件 "余额低于预定最低阔 值" 的出现。
所定义的事件可以涵盖如下内容：
1 )指示各种粒度的累积达到预定阔值的事件： 累积单位包括流量、 时 长、 消费额、 消息个数等的累积。 累积的周期包括日、 周、 月等。 累 积项可以是语音业务、 数据业务、 消息业务等业务分类； 也可以是基 于费率组的累积， 费率组是费率相同的一组业务组成的集合； 也可以 是单次业务使用的累积（用费率组和 /或业务标识识别业务）。 该类事件 的前置条件： 当前累积低于预定阔值， 或者 "累积清零" 事件出现；
2 )指示计费功能模块的累积清零的事件： 指当累积达到预定阔值后， 由于运营商定义的累积项的预置清零条件后累积数据清零， 如： 累积 策略为按天周期性累积， 则超过零点后前一天累积数据清零。 该事件 的前置条件： 当前累积达到或高于预定阔值， 或者 "累积达到预定阔 值" 事件出现；
3 )指示账户余额低于预定阔值的事件： 指用户的某个账户、 或所有账 户的余额低于某个阔值。 前置条件： 当前余额高于预定阔值， 或者 "余 额高于预定阔值" 事件出现；
4 )指示账户余额高于预定阔值的事件： 指用户的某个账户、 或所有账 户的余额高于某个阔值， 包括当用户账户余额低于预定阔值后， 由于 充值或运营商赠送等使得用户的账户余额又高于预定阔值。 前置条件： 当前余额低于预定阔值， 或者 "余额低于预定阔值" 事件出现；
5 )指示赠送流量使用的事件： 指计费功能模块开始授权用户使用运营 商赠送的流量， 而非用户自付费流量， 可能需要为赠送流量开始使用 和结束使用分别定义事件；
6 )其他计费***上的事件， 如： 一定时期内的充值次数、 充值金额等。 在本发明实施例中， 将上述定义的计费相关事件进行分类， 分类如下： 非订阅类事件： 对所有网关上的数据业务流的 QoS、 带宽等控制会产 生影响的事件， 或者运营商认为无需策略决策装置订阅的事件。 非订 阅类事件无需和特定数据业务相关， 所以无需确认当前正在使用哪些 业务， 该类事件可以通过配置生效， 即： 配置该类事件到计费***， 由计费***根据策略决策装置和计费***间的会话情况确定是否需要 上报， 而无需策略决策装置去订阅。 上述实施例中的第二类计费相关 事件和第四类计费相关事件均为该非订阅类事件；
订阅类事件： 仅对网关上的某些业务数据流会产生影响的事件， 由于 该类事件仅与某些业务相关， 所以首先要能够确定当前所使用的业务。 策略决策装置可以获知当前所使用的业务， 但计费***无法获知， 所 以该类事件需要订阅生效， 即： 策略决策装置在业务使用时或使用过 程中向计费***订阅业务相关的该类业务。 上述实施例中的第一类计 费相关事件和第三类计费相关事件均为该订阅类事件；
需要指出的是， 具体某个事件属于非订阅类事件还是订阅类事件， 根据 运营商的运营策略， 以及运营商对事件的定位确定。
进一步的， 在分类定义事件的同时， 定义事件所对应的计费***的处理 规则和策略决策装置的策略生成规则可以如下：
计费***的处理规则指的是： 计费***关联该事件到一个累积项， 或者 一个余额变化监控项上， 若为非订阅类事件， 还需要指定计费***在累积项 或余额变化达到阔值后， 自动基于一定条件上报该事件， 不管策略决策装置 是否订阅了该事件； 策略决策装置的策略生成规则指的是： 策略决策装置关联该事件到一个 或多个业务数据流， 并定义该事件和其他输入的组合作为条件时的 QoS、 带 宽等策略。
52、 管理节点将定义的计费相关事件和相应的处理规则发送到计费*** 和策略决策装置。
在本发明实施例中， 管理节点设备在定义了上述计费相关事件和对应的 处理规则后， 可以预先将上述计费相关事件和对应的处理规则发送到策略决 策装置和计费***。 管理节点设备可以基于事件分类在策略决策装置和计费 ***进行配置， 配置对象可以是单个用户、 套餐用户、 或者某个级别用户， 配置信息包括： 向策略决策装置配置业务标识、 费率组、 事件、 事件的前置 条件、 策略生成规则等中的一个或多个； 管理节点设备向计费***配置事件、 事件的前置条件、 累积规则、 事件类别等中的一个或多个， 计费***对不同 类别的事件进行不同的处理， 其中累计规则可以包括累积项、 累积方式、 累 积周期等， 事件类别可以包括订阅类和非订阅类。
53、 策略决策装置接收到网关设备发送的控制策略请求。
其中， 控制策略请求用于请求控制策略， 其中携带用户标识。
54、 策略决策装置判断是否需要和计费***建立会话。
具体的， 策略决策装置根据用户的订购数据、 用户属性、 业务属性、 运 营商策略等判定是否需要和计费***建立会话， 若需要， 进一步判定该策略 决策装置和计费***间是否已经为该用户建立了会话， 若已经建立了会话， 则重用该会话， 然后执行步骤 S7。 若没有建立会话， 则确定需要建立该策略 决策装置和和计费***间的会话， 执行步骤 S5。
55、 策略决策装置向计费***发起会话请求消息， 该请求消息中携带用 户标识和计费数据获取请求。
其中， 请求消息中携带用户标识用于计费***将会话绑定到某一具体用 户。 请求消息还可以包括获取计费***上用户当前的计费相关数据的获取请 求， 以获取会话建立时计费***上当前的用户计费相关数据， 以作为策略决 策装置上最初业务流控制策略生成的输入参数。 对于同一用户策略决策装置 和计费***之间只有一个交互会话， 所以该用户的多个业务共享该会话。
56、 计费***返回应答消息， 该应答消息中携带用户当前的计费相关数 据。 具体的， 计费***向策略决策装置发送应答消息， 表明会话建立成功。 同时， 若会话请求消息中携带了用户当前的计费相关数据的获取请求， 则在 该应答消息发送用户当前的计费相关数据给策略决策装置。
57、 策略决策装置获取订阅类事件。
具体的， 策略决策装置可以根据用户订购信息、 运营商策略等确定需要 向计费***订阅的计费相关事件。 其中， 策略决策装置可以根据业务数据流 信息、 业务信息、 费率组信息和 /或用户信息等在预置的计费相关事件组成的 集合中查找对应的计费相关事件， 若查找到， 则确定需要向计费***订阅该 计费相关事件， 即订阅类事件。 其中， 上述计费相关事件可以预先发送给策 略决策装置或在策略决策装置中预先配置， 计费相关事件的来源不应构成对 本发明实施例的限制。
58、 策略决策装置向计费***发送订阅请求。
具体的， 策略决策装置确定需要订阅的计费相关事件后， 判断该计费相 关事件的前置条件是否满足， 若是， 则通过该会话向计费***发送订阅请求。 其中， 策略决策装置在发送订阅请求之前还可以判断该用户的其他当前使用 业务是否已经在该会话中订阅了该事件， 若已经订阅， 则共享该订阅即可， 无需重复订阅。 当然， 计费***也可以在接收到策略决策装置的订阅事件请 求后， 过滤重复订阅请求。
59、 计费***接收订阅请求， 激活订阅事件的上报机制。
具体的， 计费***接收到策略决策装置的订阅请求后， 激活该订阅请求 所订阅的计费相关事件的上报机制， 即监测该订阅事件， 并在该订阅事件发 生时向策略决策装置发送通知消息， 转到步骤 Sll。
510、 计费***查找该用户对应的非订阅事件并激活上 机制。
具体的， 在完成策略决策装置与计费***的交互会话后， 计费***根据 管理节点配置在计费相关事件组成的集合中自动查找适合该用户标识的非订 阅类事件， 并在确认该非订阅类事件的前置条件满足时， 激活该非订阅类事 件的上报机制。
需要指出的是， 上述步骤 S6和 S9没有严格的执行先后顺序， 该编号上 的先后顺序和时序上的先后顺序无关。
511、 策略决策装置订阅的订阅类事件或非订阅事件发生， 计费***向策 略决策装置发送通知消息。 具体的， 计费***在监测到策略决策装置订阅的订阅类事件或非订阅事 件发生时， 向策略决策装置发送通知消息， 其中携带所发生的事件信息， 用 于表明该事件已发生。
事件发生后， 计费***还可以查找以该事件为前置条件的非订阅事件并 激活。 具体的， 计费***在某一事件出现后， 自动查找适合该用户的以该事 件的发生为前置条件的非订阅类事件， 并自动激活该非订阅类事件， 计费系 统对该激活的非订阅类事件的处理流程和其他事件的处理流程类似， 即： 计 费***激活该事件的上报设置后， 在事件发生后， 立即向策略决策装置上报 该事件， 即发送通知消息。
512、 策略决策装置接收通知消息， 生成控制策略。
具体的， 策略决策装置在接收到的计费***发送的通知消息后， 根据通 知消息中的事件信息和管理节点预先配置的策略生成规则生成控制策略。
另外， 策略决策装置还可以在接收到通知消息后， 查找以已发生的计费 相关事件为前置条件的订阅类事件并向计费***订阅。
513、 策略决策装置发送控制策略到网关设备。
具体的， 策略决策装置发送生成的控制策略到网关设备， 网关设备执行 该控制策略， 实现对用户的业务数据流的控制。
在本发明实施例四提供的策略控制方法中， 还可以包括取消订阅的步骤， 具体取消订阅有三种方法， 分述如下：
1 )策略决策装置向计费***发送取消订阅命令。 该取消订阅命令携带要 取消订阅的一个或多个或所有事件； 或者该取消订阅命令是订阅一个特殊事 件， 该特殊事件指示取消订阅所有事件， 如： 取消订阅所有事件
( UNSUBSCRIBE-ALL-EVENTS ) 事件。
2 )若用户的所有业务结束， 则策略决策装置请求中断策略决策装置与计 费***间的交互会话， 则计费***在关闭该交互会话后自动无效该策略决策 装置的所有订阅类事件， 同时无效所有计费***自动激活上 ^艮设置的非订阅 类事件；
3 )在业务使用过程中， 若计费相关事件发生， 则计费***在成功向策略 决策装置上报了该事件后， 可以自动无效该事件的上报设置。
在本发明实施例五提供的策略控制方法中， 通过管理节点基于事件分类 向策略决策模块和计费***配置事件、 事件的前置条件、 处理规则等， 基于 管理节点的配置可以区分非订阅类和订阅类事件， 对于非订阅类事件， 计费 ***可以在策略决策模块与计费***交互会话建立时自动激活非订阅类事件 的上报设置， 无需策略决策模块订阅， 由于非订阅类事件出现几率低， 且在 所有计费***能够上报给策略决策装置的事件中的占比高， 取消订阅可以大 幅降低策略决策装置和计费***处理订阅和管理订阅的花费， 降低策略决策 装置和计费***的压力， 同时实现了基于计费***丰富信息的业务数据流精 细化控制。
本发明实施例六提供了一种策略控制方法， 进一步对本发明其他实施例 的订阅方法进行详细描述。
计费***在接收到策略决策装置的订阅请求后， 根据管理节点的配置和 自身能力， 判断是否支持该请求中的某一计费相关事件或者是否能够识别该 计费相关事件或者该计费相关事件的前置条件是否满足， 如果不支持或者无 法识别该计费相关事件或者该计费相关事件的前置条件不满足， 则拒绝对该 计费相关事件的订阅， 可选的， 针对该事件返回订阅失败信息给策略决策装 置， 该失败不影响对该请求中其他的计费相关事件的订阅处理， 也就是说， 计费***会对其他计费相关事件进行相同的判断， 并不会因为该订阅失败而 拒绝对其他计费相关事件的订阅， 需要说明的是， 如果该请求中有多个订阅 失败的计费相关事件， 且需要返回失败信息给策略决策装置， 则计费***会 将对应的订阅失败信息合并在同一个应答消息中返回给策略决策装置；
或者， 计费***在判断出如果策略决策装置发送的订阅请求中只要有一 个计费相关事件不支持或不能识别或其前置条件不满足， 则拒绝该订阅请求 消息， 即拒绝该订阅请求消息中的所有事件的订阅， 并返回该请求消息的应 答消息， 指示该所有事件均订阅失败。
策略决策装置在已建立的会话中更新已订阅的事件时， 如 E2步骤， 具体 的可以通过如下方式实现：
方法一、 策略决策装置发送更新订阅消息给计费***， 该消息中仅携带 需要新增订阅的计费相关事件及订阅请求或者需要取消订阅的计费相关事件 及取消订阅请求， 并不携带不受影响的计费相关事件， 计费***接收到该更 新订阅消息后， 基于该策略决策装置之前订阅的事件组和该更新消息， 增加 新的计费相关事件的订阅， 并取消订阅该消息请求取消订阅的计费相关事件； 方法二、 策略决策装置发送更新订阅消息给计费***， 该消息中必须携 带所有的计费相关事件及订阅请求， 即： 包括新增订阅的计费相关事件和已 经订阅的但仍然需要订阅的计费相关事件， 也就是需要发送当前需要订阅的 所有计费相关事件， 计费***接收到该更新订阅消息后， 取消该策略决策装 置之前订阅的所有事件， 并对该更新订阅消息中的所有计费相关事件执行订 阅操作。
