302、 PCEF进行业务检测;
当有下行数据报文经过时, PCEF 基于 IP 五元组或者深度报文解析 ( Deep packet inspection, DPI )等技术进行业务检测。 当 PCEF检测到新 业务时, PCEF将检测结果上报给 PCRF。 示例性的, 可釆用业务检测功能 ( Traffic Detection Function, TDF )机制和 Gx/Sd接口实现 PCEF将检测结 果 的 上 报 至 PCRF , 例 如 在 CC-Request 消 息 中 的 Application-Detection-lnformation信元携带检测到的业务信息。 PCEF 获取下行数据报文的 FPI , 可以如 303a~303b 所示, 也可以如 303c~303e所示。

表 1
Figure imgf000010_0001
再例如, PCRF 也可以根据该下行数据报文所属业务的业务优先级、 该 下行数据报文所属业务的用户累计使用量等级、 该下行数据报文所属业务的 用户等级和接收该下行数据报文的 UE 的类型中的至少一项通过某个特定公 式计算出 FPI。
上述该下行数据报文所属业务的业务优先级、 该下行数据报文所属业务 的用户累计使用量等级、 该下行数据报文所属业务的用户等级和接收该下行 数据报文的 UE的类型等下行数据报文相关的参数只是示例性的举例, 实际 应用中可以釆用其他服务质量参数, 本发明实施例对此不作限定。 303b, PCRF发送该该下行数据报文对应的 FPI至 PCEF; 示例性的, PCRF可以通过 Gx接口下发策略与计费控制 (Policy and Charging Control PCC )规则至 PCEF,其中包含该下行数据报文对应的 FPI, 例如在 CC-Answer消息中的 Charging-Rule-lnstall信元中携带该下行数据报 文对应的 FPI。

304、 PCEF在下行数据报文中携带获得的 FPI;
示例性的, PCEF 可以通过用户面数据报文标记方式在下行数据报文中 携带 FPI。 例如可以在下行数据报文的隧道封装头中携带 FPI或者在 IP报文 头中携带 FPI, 以下的举例说明, 并不构成对于本发明实施例的限制。
1 )通过隧道封装头携带 FPI。
对于 GPRS隧道协议(GPRS Tunneling Protocol, GTP )接口, 例如 Gn/Gp、 S5/S8和 lu接口, 可以釆用 GTP-U头扩展方式携带 FPI, 如表 2 和表 3所示, 其中扩展头类型为 00, 用以不影响其他网元。 表 2
Figure imgf000012_0001
表 3
Figure imgf000012_0002
对于代理移动 IP协议第六版本( PMIPv6 ) 的接口, 例如 S2a, S2b而 言, 可以在通用路由封装 ( Generic Routing Encapsulation, GRE )中增加字 段携带 FPI, 也可以利用现有 GRE封装中的 ReservedO或 ReservecM信元 来携带所述 FPI, 如表 4所示。
表 4
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
Figure imgf000012_0003
2)在 IP报文头中携带 FPI, 则不需要扩展隧道封装;
例如,对于 IPv4报文,可以釆用差分服务编码点( Differentiated Services Code Point, DSCP) 字段来标识 FPI, 如表 5所示。 其中, 本实施例仅针对 隧道内应用层 IP头中 DSCP携带所述 FPI, 所以不会影响中间节点的调度, 也不受中间节点改写隧道外层 IP头中 DSCP的影响。
表 5
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
Figure imgf000013_0001
再例如, 对于 IPv6报文而言, 可以釆用 Traffic Class字段来携带所述 FPI, 如表 6所示。
表 6
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
Figure imgf000013_0002
需要说明的是, 上述携带 FPI的方式仅仅是常用的几种实例, 但具体应 用时并不局限于此, 本文在此不再赘述。
305、 PCEF发送下行数据报文至基站。
可选的, PCEF可以根据下行数据报文的 FPI来发送下行数据报文。 示 例性的, PCEF可以基于 FPI对下行数据报文进行优先级排序和调度, 优先 发送业务流优先等级高的下行数据报文。
可选的, 下行数据报文经过中间节点时, 中间节点也可以根据下行数据 报文的 FPI来转发下行数据报文。 示例性的, 中间节点可以基于 FPI对下行 数据报文进行优先级排序和调度, 优先发送业务流优先等级高的下行数据报 文。
306、 基站根据下行数据报文的 FPI发送下行数据报文至 UE。
本实施例中基于 FPI发送下行数据报文可以由多种方式实现, 本实施例 仅以下述方式进行说明, 但并不局限于此。 例如, 可以根据根据 FPI所指示 的业务流的优先等级的顺序来发送下行数据报文至 UE,也可以根据 FPI所对 应的权重信息来发送下行数据报文至 UE,或者可以根据 FPI所对应的权重信 息, 以及该下行数据报文所属的承载所对应的权重信息来发送下行数据报文 至 UE。
下面以根据 FPI对应的权重信息和下行数据报文对应的承载的权重信息 来发送下行数据报文进行说明。
例如, 如表 7所示, 某小区内有三个用户, 每用户各一个承载, 权重分 别为 100, 50和 50; 每个承载有三个队列, 权重分别是 60、 30和 10, 每 个队列可对应 2个不同 FPI。 当有下行数据报文经过时, 可以根据该下行数 据报文所属的承载和该下行数据报文的 FPI , 将该下行数据报文插入相应的 队列中。 当基站发送下行数据报文时, 先按承载的权重分配各承载的调度机 会(2: 1 : 1 ), 一旦该承载得到调度后, 再根据该承载的队列的权重分配队 列的调度机会(6: 3: 1 ), 来选择相应队列中的下行数据报文进行发送, 基 于此可对优先级别高的业务流的下行数据报文进行优先发送, 优先级别低的 业务流的下行数据报文延迟发送, 实现了基于业务流粒度的端到端的服务质 量的控制, 能够对业务流进行端到端的差异化处理, 为不同等级的用户和不 同类型的业务提供差异化的业务体验, 有效的提高了无线资源利用效率。
