步骤 S1004, 应用系统向策略控制系统请求上述高优先级网络服务策略。 通过本发明实施例, 应用系统确定用户需要高优先级网络服务策略, 并向策略控 制系统请求该高优先级网络服务策略, 使得策略控制系统能够根据应用系统的请求为 用户设置高优先级网络服务策略, 实现了应用系统与网络联动, 从而在网络上为用户 实施网络质量保证, 提高了用户的业务体验。 在本发明实施例的一个优选实施方式中, 应用系统确定用户需要高优先级网络服 务策略时, 应用系统可以确定用户需求的网络服务策略, 并判断用户当前状态下的网 络服务策略是否低于需求的网络服务策略, 如果是, 则确定用户需要高优先级网络服 务策略。 优选地, 应用系统可以依据用户选择的服务和 /或用户的属性信息确定用户需 求的网络服务策略。 在本发明实施例的一个优选实施方式中,应用系统还可以维护用户的服务状态机, 其中, 服务状态机设置为记录用户的服务状态。 在实际应用中, 服务状态可以包括: 开启状态、 关闭状态、 普通优先级服务状态, 高优先级服务状态等, 根据实际需要可 以设备多个服务状态优先级, 针对不同的用户和 /或服务提供不同等级的网络服务策 略。 在本发明实施例中, 可以在用户与应用系统建立连接时, 将用户的服务状态记录 为开启状态; 用户与应用系统建立连接后, 按照普通优先级为用户提供服务; 当应用 系统确定用户需要高优先级网络服务策略, 则请求高优先级网络服务策略, 如果成功, 则记录用户为高优先级服务状态。 用户服务完成或连接出现异常时, 记录用户的服务 状态为关闭状态。 在本发明实施例中,应用系统向策略控制系统请求上述高优先级网络服务策略后, 策略控制系统可以向用户接入的网络业务控制设备下发高优先级网络服务策略, 网络 业务控制设备接收该高优先级网络服务策略,并为用户设置该高优先级网络服务策略。 优选地, 策略控制系统可以根据用户的源 IP地址、 端口号对应到相应的用户, 检查用 户的在线状态及策略状态, 向网络业务控制设备下发高优先级网络服务策略。 在实际应用中, 在网络业务控制设备上设置了网络质量限制的情况下, 例如, 限 制了用户的带宽等, 网络业务控制设备可以在该网络业务控制设备上设置上述高优先 级网络服务策略。 在接入网上设置了网络服务策略限制的情况下, 网络业务控制设备 可以指示接入网为用户设置高优先级网络服务策略, 优选地, 网络业务控制设备可以 通过 ANCP协议, 与接入网设备协商提升用户的接入带宽。 优选的, 网络业务控制设备还可以在高优先级网络服务策略执行之后, 向策略控 制系统反馈网络服务策略的执行结果。 策略控制系统还可以接收网络业务控制设备反 馈的执行结果, 并向应用系统反馈接收到的执行结果。 因此, 应用系统向策略控制系 统请求所述高优先级网络服务策略之后, 还可以根据请求的执行结果更新用户的服务 状态。 优选地, 在请求执行成功的情况下, 应用系统更新用户的服务状态为高优先级 服务状态; 在请求执行失败的情况下, 应用系统保持用户请求高优先级网络服务策略 之前的服务状态。 优选地, 如果请求执行失败, 则应用系统可以根据预设策略, 再次向策略控制系 统请求高优先级网络服务策略。 例如, 在预定时间后, 应用系统判断用户当前的服务 状态, 如果用户为低优先级服务状态, 或普通优先级服务状态, 则再次向策略控制系 统请求高优先级网络服务策略; 在本发明实施例的一个优选实施方式中, 在用户选择的服务完成或用户的连接状 态出现异常的情况下, 应用系统向所述策略控制系统发送用于请求撤销高优先级网络 服务策略的请求。 优选地, 应用系统还可以更新用户的状态为关闭状态。 在实际应用中, 应用系统可以维护用户的服务状态机, 如图 3所示, 应用系统根 据自身策略为该用户建立服务状态机, 当用户在应用系统中选择了服务, 应用系统设 置该用户进入 so (开启状态); 用户在 so状态, 尝试建立服务连接,连接成功建立后, 应用系统设置该用户进入 S1 (普通服务状态); 如连接建立失败, 则尝试相应的等待 和重新链接机制,重复链接不成功且超过相应的限制,则应用系统设置用户进入 S3 (关 闭状态), 释放相应的资源。 用户进入 S1后,触发应用系统向策略控制系统或网络业务控制设备请求高优先级 网络服务策略。 策略执行成功后, 应用系统设置用户进入 S2 (高优先级服务状态); 如策略执行失败, 应用系统设置用户维持在 S1 ; 用户在 S1下, 完成下载任务时, 需 要断开下载链接, 此时, 用户处于 Sl, 应用系统设置用户直接进入 S3 ; 用户在 S1下, 下载过程中, 用户链接异常中断, 则直接进入 S3(关闭状态)。 用户在 S2下, 完成下载任务, 需要断开下载链接, 触发应用系统向策略控制系统 或网络业务控制设备请求撤销该用户的高优先级网络服务策略, 策略撤销后, 然后应 用系统设置用户进入 S3, 释放相应的资源; 如在下载过程中, 用户链接异常中断, 也 触发应用系统向策略控制系统或网络业务控制设备请求撤销该用户高优先级网络服务 策略, 策略撤销后, 然后应用系统设置用户进入 S3, 释放相应的资源。 在本发明实施例中, 应用系统可以通过以下两种方式向策略控制系统请求高优先 级网络服务策略: 一、 应用系统直接向策略控制系统发送用于请求高优先级网络服务 策略的请求; 或者, 二、 应用系统通过网络业务控制设备向控制策略系统发送用于请 求高优先级网络服务策略的请求。 下面分别对上述两种实现方式进行描述。 方式一 在方式一中, 应用系统直接向策略控制系统发送用于请求高优先级网络服务策略 的请求, 下面对方式一进行详细描述。 在应用系统中增加服务状态机, 管理用户的连接状态和网络上传 /下载状态, 应用 系统可基于用户状态机, 区分出高等级用户和普通用户, 实施差异化的服务; 区分付 费用户和免费用户, 实施差异化运营。 并在应用系统中增加与网络策略控制系统之间 的接口, 使得应用系统具备和网络策略控制系统的通信机制, 实现应用和网络联动。 用户在应用系统服务页面选择应用时 (如高速下载, 高清视频, 付费视频, 用户 为会员等),应用系统建立和维护用户状态, 并根据状态触发向策略控制系统请求针对 用户的高优先级网络质量保障策略, 策略控制系统向网络设备下发针对该用户的高优 先级网络策略。 用户业务下载完成, 根据用户完成状态, 触发应用系统向策略控制系 统撤销高优先级网络策略, 恢复用户原来的网络策略。 在本发明实施例中, 应用系统增加了与策略控制系统进行交互的接口, 从而使得 应用系统具备了和网络策略控制系统的通信机制,有了应用和网络联动的基础。并且, 应用系统增加了用户状态机, 维护用户的连接状态和服务状态, 从而使得应用系统可 以针对特定的用户在特定的时间段内, 针对特定的内容, 实施特定的网络保障策略, 提升用户体验; 同时, 基于用户的状态控制, 实现的精细化的控制和运营。 优选地,应用系统可以记录用户所选的内容服务,以及用户的源 IP地址和端口号, 结合用户的状态机, 并通过与策略控制系统的接口, 实时与策略控制系统交互, 从而 使系统具备了基于业务状态触发网络策略实施的能力。 应用系统维持与用户终端的链 接, 维护着用户的状态信息, 下载完成时, 触发用户状态的变更, 触发应用系统向策 略控制系统发送网络策略变更的请求, 完成应用内容和网络策略的联动。 下面结合图 11对方式一的方法进行详细描述, 在图 11中, 方式一涉及的系统主 要包括如下几个部分: 用户终端、 接入网络、 网络业务控制设备 (例如, 宽带接入服 务器(Broadband Remote Access Server, 简称为 BRAS)等)、 应用系统(如文件下载, 视频应用等)、 策略控制系统、 鉴权、 授权及计费服务器 (Authentication Authorization and Accounting, 简称为 AAA) 认证系统。 图 11是根据本发明实施例方式一的网络策略的控制方法的流程图,如图 11所示, 该方法包括步骤 S1102至步骤 S1126。 步骤 S1102, 用户终端接入网络, 发起网络接入请求。 步骤 S1104, 网络业务控制设备(BRAS)收到用户的网络接入请求, 建立并维护 用户状态, 并向 AAA认证系统发起用户接入请求。 步骤 S 1106, AAA认证系统对用户进行认证, 认证通过, 则向网络业务控制设备 发送该用户认证通过消息, 以及相应的用户网络策略; 网络业务控制设备收到认证通 过消息, 为用户分配相应的 IP地址和应用相应的网络策略。 步骤 S1108, 为了使得策略控制系统中的用户状态能够和网络业务控制设备上的 用户状态同步,在网络业务控制设备向 AAA认证系统发送用户上线计费包,通知 AAA 系统用户已经开始使用网络服务, 开始计费; 同时, 也需要发送同样的一份信息到策 略控制系统; 策略控制系统收到用户上线信息之后, 维持用户的在线状态以及用户当 前的网络策略状态 (为了后续策略控制系统能方便向用户所在的网络业务控制设备下 发策略信息, 建议在用户上线信息中携带 NAS-IP属性, 指明该用户所在的网络业务 控制设备)。 步骤 S1110, 用户在应用系统中选择相应的服务, 可以是文件下载, 也可以是视 频应用等; 应用系统根据自身的策略 (如: 用户为会员, 高等级用户, 或用户选择了高 等级应用服务), 为该用户建立相应的服务状态机。 步骤 S1112, 应用系统记录用户选择的应用信息以及用户的标识信息; 同时应用 系统需要增加和策略控制系统的通信接口 (如:可采用简单对象访问协议(Simple Object Access Protocol, 简称为 SOAP)、 Diameter、 公共开放策略服务 ( Common Open Policy Service, 简称为 COPS) ), 将用户的高优先级保障请求, 发送到策略控制平台, 消息 中应至少包含, 用户的源 IP地址, 源端口号。 步骤 S1114, 策略控制系统收到请求, 根据用户的源 IP地址, 端口号对应到相应 的用户, 检查用户的在线状态以及策略状态; 向网络业务控制设备下发高优先级网络 策略, 针对接入网, 可分为两种情况: 一种情况是接入网针对用户线路进行了速率限 制, 这种情况需要网络业务控制设备通过 ANCP协议提升用户的接入带宽; 另外一种 情况是接入网没有针对用户进行速率限制, 这种情况只需在接入网部署时部署相应的 服务质量 (Quality of Service, 简称为 QoS) 保障。 步骤 S1116, 网络策略执行后, 网络业务控制设备向策略控制系统反馈执行的结 果信息。 步骤 S1118, 策略控制系统收到网络业务控制设备的反馈信息后, 向应用系统反 馈相应的策略执行结果信息。 应用系统收到策略系统反馈的信息, 决定用户的状态机 迁移。 网络策略成功执行后, 用户的下载可以得到相应的网络保障。 用户下载完成或 用户链接异常中断, 触发应用系统向策略控制系统发送撤销该用户高优先级网络策略 的消息。 步骤 S1120, 在用户下载完成后, 或链接异常中断, 应用系统向策略控制系统请 求撤销该用户的高优先级网络策略。 步骤 S1122, 策略控制系统收到撤销该用户的高优先级网络策略消息, 检查用户 在线状态和策略状态, 向网络业务控制设备下发撤销高优先级网络策略的消息;

在应 用系统中增加与网络业务控制设备之间的接口。 用户在应用服务页面选择应用时 (如高速下载, 高清视频, 付费视频, 用户为会员 等), 应用系统建立和维护用户状态, 并根据状态触发向网络业务控制设备请求針对 户的高优先级网络质量保障策略; 网络业务控制设备向策略控制系统申请针对该用户 的高优先级网络质量保障策略, 策略控制系统向网络设备下发针对该用户的高优先级 网络策略。 用户业务下载完成, 根据用户完成状态, 触发应用系统向网络业务控制设备请求 撤销该用户的高优先级网络策略, 恢复用户原来的网络策略, 网络业务控制设备向策 略控制系统申请撤销该用户的高优先级网络策略, 并将相应的执行结果向应用系统反 馈, 使得应用系统结束用户状态机。 在本发明实施例中, 应用系统增加了与网络业务控制设备交互的接口, 使得应用 系统具备和网络策略控制系统的通信机制, 实现了应用和网络联动的基础。 应用系统 增加了用户状态机, 维护用户的连接状态和服务状态, 使得应用系统可以针对特定的 用户在特定的时间段内, 针对特定的内容, 实施特定的网络保障策略, 提升用户体验; 同时, 基于用户的状态控制, 实现了精细化的控制和运营。 优选地,应用系统可以记录用户所选的内容服务,以及用户的源 IP地址和端口号, 结合用户的状态机, 并通过与网络业务控制设备的接口, 实现和网络的联动, 使得系 统具备基于业务状态触发网络策略请求和实施的能力。 应用系统, 维持着与用户终端 的链接, 维护着用户的状态信息, 下载完成时, 触发用户状态的变更, 也会触发应用 系统向网络业务控制设备发送网络策略变更的请求;完成应用内容和网络策略的联动。 所述应用系统可基于用户状态机, 区分出高等级用户和普通用户, 实施差异化的服务;
