背景技术 在演进分组通信系统(Evolved Packet System; 简称: EPS ) 中提供了以承 载(Bearer )为粒度的服务质量(Quality of Service; 简称: QoS )控制机制, 用 户的业务数据流通过在 EPS 中建立的承载在 UE和业务服务器之间传输, EPS 以承载为粒度为业务数据流提供可用带宽, 保证业务的保障传输速率, 并限制 业务的最高传输速率。
图 1为现有技术中承载绑定所基于的 EPS的结构示意图, 如图 1所示, 该 承载绑定所基于的 EPS包括: 策略和计费规则功能(Policy and Charging Rules Function ; 简称: PCRF ) 11、 分组数据网关 ( Packet Data Network Gateway; 简 称: PGW ) 12、 服务网关 ( Serving Gateway; 简称: SGW ) 13、 移动管理实体 ( Mobility Management Entity; 简称: MME ) 14、 演进基站( Evolved NodeB; 简称: eNodeB ) 15和用户设备(User Equipment; 简称: UE ) 16。
该承载绑定的一种具体实现方式为: PGW 12接收 PCRF 11发送的策略和计 费控制(Policy and Charging Control; 简称: PCC )规则(rule ), 并根据 PCC rule 中的服务质量级别标识(QoS Class Identifier; 简称: QCI )和分配和保留优先级 ( Allocation and Retention Priority; 简称: ARP ), 将当前 PCC rule对应的业务 数据流绑定到与该 QCI和 ARP赋值相同的现有承载中, 或者为当前 PCC rule 对应的业务数据流建立一个新的承载。 当将当前 PCC rule对应的业务数据流绑 定到与该 QCI和 ARP赋值相同的现有承载中, 则 PGW 12向 SGW 13发起承载 修改流程,即修改现有承载,用于承载该当前 PCC rule对应的业务数据流, SGW 13依据来自 PGW 12的修改消息, 继续执行修改程序, MME 14接收 SGW 13 发送的修改消息,继续执行修改程序, eNodeB 15接收到 MME 14发送的修改消 息, 继续执行修改程序, UE 16接收到 eNodeB 15发送的修改消息, 继续执行修 改程序。 当为当前 PCC rule对应的业务数据流建立一个新的承载, 则 PGW 12 向 SGW 13发起承载建立流程, 建立新的承载, SGW 13依据来自 PGW 12的承 载建立消息, 继续执行承载建立, MME 14接收 SGW 13发送的承载建立消息, 继续执行承载建立 , eNodeB 15接收到 MME 14发送的承载建立消息 ,继续执行 承载建立, UE 16接收到 eNodeB 15发送的承载建立消息, 继续执行承载建立。
但是, 当两个业务数据流共用同一承载, 第一业务数据流的保证比特率 ( Guaranteed Bit Rate;简称: GBR )为 GBR1 ,第二业务数据流的 GBR为 GBR2, 且该承载的保证速率为 GBR1+ GBR2时, 第一业务数据流的速率由于业务特点 (例如该第一业务数据流为视频业务), 可能会持续超过 GBR1 , 从而导致了第 二业务数据流的速率不能达到 GBR2, 因此, 导致了第二业务数据流的 QoS不 能被满足, 进而使得用户的体验度变差。

图 5为本发明 PGW的一个实施例的结构示意图;
图 6为本发明 PCRF的一个实施例的结构示意图;
图 7为本发明 QoS执行设备的一个实施例的结构示意图。 具体实施方式 图 2为本发明业务数据流的处理方法的一个实施例的流程图, 如图 2所示, 本实施例的方法包括:
步骤 101、 PGW接收 PCRF发送的 PCC rule,该 PCC rule包括业务数据流标识、 QCI和 ARP。
在本实施例中, PCRF首先判断业务数据流中的业务信息是否满足速率控制 条件, 其中, 速率控制条件可以包括如下一种或者几种: 用于建立新承载的特 定业务类型、 用于建立新承载的特定传输机制和用于建立新承载的特定传输协 议。 具体的, 特定业务类型可以包括如下一种或者几种: 视频业务类型、 音频 业务类型、 实时视频类型、 交互视频类型和点播视频业务类型等。 特定传输机 制可以包括如下一种或者几种: 承载于超文本传输协议(Hyper Text Transfer Protocol; 简称: HTTP ) 的动态适应流媒体 ( Dynamic Adaptive Streaming over HTTP; 简称: DASH )和渐进式下载(Progressive Download )等。 特定传输协 议可以包括如下一种或者几种: 超文本传输协议( Hyper Text Transfer Protocol; 简称: HTTP )和实时传送协议 ( Real-time Transport Protocol; 简称: RTP )等。
另外, 在本实施例中, 业务信息可以包括如下一种或者几种: 业务类型、 传输机制和传输协议。 当业务数据流中的业务信息中的业务类型、 传输机制和 传输协议有一个满足速率控制条件, 例如: 当业务信息中的业务类型为视频业 务类型时, 可能会对共用承载的其他业务数据流的 QoS造成影响, 则对该业务数 据流对应的 PCC rule进行配置, 使得配置后的 PCC rule满足新承载建立条件, 即 保证 PGW将为该业务数据流建立新的承载,再将配置后的 PCC rule发送给 PGW。 当业务数据流中的业务信息的业务类型均不满足速率控制条件时, 直接将数据 流对应的 PCC rule发送给 PGW。
步骤 102、 PGW判断该 PCC rule是否满足新承载建立条件, 若该 PCC rule满 足所述新承载建立条件, 则根据该 QCI和 ARP, 建立第一承载, 并将该业务数据 流标识对应的业务数据流绑定在该第一承载上。
在本实施例中, 数据流可以表示单个数据流, 也可以表示数据流的聚集, 即多个数据流组成的一个集合。
另外, PGW向 SGW发起承载建立流程, 建立第一承载, SGW依据来自 PGW的承载建立消息,继续执行第一承载建立, MME接收 SGW发送的承载建 立消息, 继续执行第一承载建立, eNodeB接收到 MME发送的承载建立消息, 继续执行第一承载建立。
在本实施例中, 通过判断接收到的 PCRF发送的 PCC rule是否满足新承载建 立条件, 若满足该新承载建立条件, 则说明该业务数据流的速率由于业务特点, 会持续超过其本身的 GBR, 为了避免导致与该业务数据流共用同一承载的其他 业务数据流的 QoS不能被满足, 则根据 PCC rule中的 QCI和 ARP, 建立第一承载, 并将 PCC rule中的业务数据流标识对应的业务数据流绑定在该第一承载上,从而 保证了用户的体验度。
进一步的, 在本发明的另一个实施例中, 在上述图 2所示实施例的基础上, 当 PCRF业务数据流中的业务信息满足速率控制条件时, 在该业务数据流对应的 PCC rule中设置用于建立新承载的特定的 QCI和 /或特定的 ARP,该特定的 QCI和、 或特定的 ARP可以为 PCRF和 PGW预先共同约定的用于建立新承载的 QCI和 /或 ARP, 也可以根据之前对 PCC rule设定的 QCI和 /或 ARP选择不相同的 QCI和 /或 ARP。
将设置后的 PCC rule发送给 PGW, 则上述步骤 102的一种具体实现方式为: PGW判断该 QCI是否与特定的 QCI相同和 /或该 ARP是否与特定的 ARP相 同, 若该 QCI与特定的 QCI相同和 /或该 ARP与特定的 ARP相同, 则根据该 QCI和 ARP, 建立第一承载, 并将该业务数据流标识对应的业务数据流绑定在该第一 承载上。 另外, 需要说明的是, 当 PGW判断出该 QCI与特定的 QCI不相同且该 ARP与 特定的 ARP也不相同, 则查询是否存在与该 QCI和 ARP赋值相同的承载, 若查询 存在与该 QCI和 ARP赋值相同的承载, 则设置与该 QCI和 ARP赋值相同的承载为 第二承载, 并将该业务数据流标识对应的业务数据流绑定在该第二承载上。 若 查询不存在与该 QCI和 ARP赋值相同的承载, 则根据该 QCI和 ARP, 建立新的承 载, 并将该业务数据流标识对应的业务数据流绑定在该新的承载上。
更进一步的,在本发明的又一个实施例中,在上述图 2所示实施例的基础上, 当 PCRF业务数据流中的业务信息满足速率控制条件时, 在该业务数据流对应的 PCC rule中设置特定指示标识,且设置该特定指示标识为新承载建立的特定指示 标识, 并将设置后的 PCC rule发送给 PGW, 则步骤 102的另一种具体实现方式可 以为:
PGW判断该 PCC rule中是否还包括特定指示标识,且判断该特定指示标识是 否为新承载建立的特定指示标识。 若判断出该 PCC rule中包括特定指示标识, 且 该特定指示标识为新承载建立的特定指示标识, 则根据该 QCI和 ARP, 建立第一 承载, 并将该业务数据流标识对应的业务数据流绑定在该第一承载上。
在本实施例中, 举例来说, PCRF在该业务数据流对应的 PCC rule中设置特 定指示标识, 该特定指示标识可以为布尔数学( Boolean )数值, 当 Boolean数值 为 "True" 时, 表示新? 载建立的特定指示标识; 当 Boolean数值为 "False" 时, 表示非新承载建立的特定指示标识。 则 PGW接收到该 PCC rule后, 判断该 PCC rule中是否包括 Boolean数值, 并判断该 Boolean数值是 "True" 还是 "False" , 若是 "True" , 则根据 PCC rule中的 QCI和 ARP, 建立第一承载; 若是 "False" , 则查询是否存在与该 QCI和 ARP赋值相同的承载, 若查询存在与该 QCI和 ARP赋 值相同的承载, 则设置与该 QCI和 ARP赋值相同的承载为第二承载, 并将该业务 数据流标识对应的业务数据流绑定在该第二承载上。 若查询不存在与该 QCI和 ARP赋值相同的承载, 则根据该 QCI和 ARP, 建立新的承载, 并将该业务数据流 标识对应的业务数据流绑定在该新的 7 载上。
图 3为本发明业务数据流的处理方法的还一个实施例的流程图, 如图 3所示, 本实施例的方法包括:

步骤 203、 PCRF将配置后的 PCC rule发送给 PGW, 以供该 PGW根据该配置 后的 PCC mle, 对该业务数据流进行处理。 赘述。 另外, 当业务数据流中的业务信息中的业务类型、 传输机制和传输协议 有至少一个满足速率控制条件, 例如: 业务类型为视频业务类型时, 可能会对 共用承载的其他业务数据流的 QoS造成影响, 则对该业务数据流对应的 PCC rule 进行配置,使得配置后的 PCC rule满足新承载建立条件, 即保证 PGW将为该业务 数据流建立新的承载,再将配置后的 PCC rule发送给 PGW。 当业务数据流中的业 务信息的业务类型均不满足速率控制条件时,直接将数据流对应的 PCC rule发送 给 PGW。
在本实施例中, 通过 PCRF判断出业务数据流中的业务信息满足速率控制条 件, 则将该业务数据流对应的 PCC rule进行配置, 使得配置后的 PCC rule满足新 承载建立条件, 并将配置后的 PCC rule下发给 PGW, 以供 PGW根据该配置后的 PCC rule, 为该业务数据流建立新的承载, 从而避免导致与其共用同一承载的其 他业务数据流的 QoS不能被满足, 进而保证了用户的体验度。
进一步的, 在本发明的再一个实施例中, 在上述图 3所示实施例的基础上, 步骤 202中的对该业务数据流对应的 PCC rule进行配置的一种具体实现方式可以 具体为:

在该业务数据流对应的 PCC rule中设置特定指示标识,且设置该特定指示标 识为新承载建立的特定指示标识。
在本实施例中, 该特定指示标识可以为 Boolean数值, 当 Boolean数值为 "True" 时, 表示新? 载建立的特定指示标识; 当 Boolean数值为 "False" 时, 表示非新承载建立的特定指示标识。
图 4为本发明业务数据流的处理方法的又一个实施例的流程图, 如图 4所 示, 本实施例的执行主体为 QoS执行设备, 则该方法包括:
步骤 301、 获取第一承载以及该第一承载对应的业务参数。
在本实施例中, PGW接收 PCC rule, 并根据 PCC rule中的 QCI和 ARP, 将当 前 PCC rule对应的业务数据流绑定到与该 QCI和 ARP赋值相同的现有承载中, 或 者为当前 PCC rule对应的业务数据流建立一个新的承载。 当将当前 PCC rule对应 的业务数据流绑定到与该 QCI和 ARP赋值相同的现有承载中, 则 PGW向 SGW发 起携带业务参数的承载修改消息, 即修改现有承载, 用于承载该当前 PCC rule 对应的业务数据流, 并接收该业务参数, SGW依据来自 PGW的承载修改消息, 继续执行修改程序; MME接收 SGW发送的携带有该业务参数的承载修改消息, 继续执行修改程序; eNodeB接收到 MME发送的携带有该业务参数的承载修改消 息, 继续执行修改程序; UE接收到 eNodeB发送的携带有该业务参数的承载修改 消息, 继续执行修改程序。 当为当前 PCC rule对应的业务数据流建立一个新的承 载,则 PGW向 SGW发起携带有该业务参数的承载建立消息,建立新的承载, SGW 依据来自 PGW的承载建立消息, 继续执行承载建立, 并接收该业务参数; MME 接收 S GW发送的携带有该业务参数的承载建立消息, 继续执行承载建立; eNodeB接收到 MME发送的携带有该业务参数的承载建立消息,继续执行承载建 立; UE接收到 eNodeB发送的携带有该业务参数的承载建立消息, 继续执行承载 建立。 其中, 该业务参数可以包括如下一种或者几种的: 业务信息、 QCI、 ARP, 传输流模板( Traffic Flow Template; 简称: TFT )和业务数据流标识等。 该业务 信息包括如下一种或者几种: 业务类型、 传输机制、 传输协议、 MBR和 GBR。
另外, 在本实施例中, QoS执行设备可以为: eNodeB或者 UE等。 当 QoS执 行设备为 eNodeB时, 该 eNodeB接收 MME发送的承载修改消息或者承载建立消 息,获取第一承载, 并通过 SGW和 MME接收 PGW发送的第一承载对应的业务参 数。 当 QoS执行设备为 UE时, 该 UE接收 eNodeB发送的承载修改消息或者承载建 立消息, 获取第一承载, 并通过 SGW、 MME和 eNodeB接收 PGW发送的第一承 载对应的业务参数。
步骤 302、 根据该业务参数, 分别对该第一承载中的业务数据流的速率进行 速率控制处理。
在本实施例中, 该第一承载中的业务数据流可以是第一承载中的部分业务 数据流, 也可以是第一承载中的全部数据流。
在本实施例中, 通过根据获取的第一承载以及该第一承载对应的业务参数, 分别对第一承载中的业务数据流的速率分别进行速率控制处理, 为可能导致其 共用同一承载的其他业务数据流的 QoS不能被满足的业务数据流建立新的承载, 从而保证了用户的体验度。
进一步的, 在本发明的还一个实施例中, 在上述图 4所示实施例的基础上, 当获取到该第一常在对应的速率控制条件, 以及该业务参数包括: 业务信息、 QCL ARP和 TFT, 且该业务信息包括如下一种或者几种: 业务类型、 传输机制 和传输协议时, 步骤 302的一种具体实现方式可以为:
在该第一承载中, 识别与该 TFT对应的业务数据流, 并分别判断该业务 数据流对应的中的业务信息是否满足速率控制条件;
分别根据满足速率控制条件的业务数据流对应的 QCI和 ARP, 建立第二承 载, 并将该业务数据流绑定到该第二承载上。
在本实施例中, 速率控制条件可以包括如下一种或者几种的组合: 用于建 立新承载的特定的业务类型、 用于建立新承载的特定的传输机制和用于建立新 承载的特定的传输协议。 具体的, 业务类型可以包括如下一种或者几种: 视频 业务类型、 音频业务类型、 实时视频类型、 交互视频类型和点播视频业务类型 等。传输机制可以包括如下一种或者几种::承载于 DASH和 Progressive Download 等。 传输协议可以包括如下一种或者几种: HTTP和 RTP等。
举例来说, 在本实施例中, 当业务数据流中的业务信息中的业务类型、 传 输机制和传输协议有至少一个满足速率控制条件, 例如: 业务类型为视频业务 类型时, 可能会对共用承载的其他业务数据流的 QoS造成影响, 则根据该业务数 据流对应的 QCI和 ARP, 建立第二承载, 并将该业务数据流对应的 TFT绑定到该 第二承载上。 更进一步的,在本发明的再一个实施例中,在上述图 4所示实施例的基础上, 该业务参数包括业务信息和 TFT, 且该业务信息包括 GBR时, 步骤 302的另一种 具体实现方式为:
在该第一承载中, 识别与该 TFT对应的业务数据流; 分别判断该业务数 据流对应的的速率是否大于该业务数据流对应的 GBR, 并将速率大于 GBR的业 务数据流对应的速率设置为该业务数据流对应 GBR获取 TFT对应的业务数据流 的速率, 并判断该速率是否大于该 TFT对应的 GBR, 若判断出大于, 则将该速率 设置为该 GBR。
在本实施例中,该方法还可以具体釆用令牌桶算法或者漏桶算法对该业务 数据流进行对应的速率进行设置。
另外, 当该第一承载中还剩余带宽资源, 则该方法还包括:
将该剩余带宽资源分配给对至少一个 GBR小于 MBR的设置后的数据流。 在本实施例中, 为了保证承载中的各个业务数据流的 QoS, QoS执行设备识 别 TFT对应的业务数据流, 并获取该业务数据流对应的速率, 并判断该速率是否 大于该业务数据流对应的 GBR, 若判断出该速率大于该业务数据流对应的 GBR, 则将该速率设置为该 GBR, 即优先保障该业务数据流中等于 GBR部分的数据传 输。若判断出所述业务数据流对应的速率小于或等于业务数据流所对应的 GBR, 则保障业务数据流的全部数据的传输。
另外, 还需要说明的是, 该业务参数还可以包括 MBR, 若承载的保证速率 大于承载中所有业务数据流的速率之和, 则可以将持续超出其 GBR的业务数据 流的速率提高, 并保证提高的速率小于等于其 MBR, 且与其他业务数据流的速 率之和小于等于承载的保证速率。 举例来说, 该第一承载的保证速率为 3M, 该 第一承载包括两个业务数据流, 具体为, 第一业务数据流和第二业务数据流, 其中, 第一业务数据流的速率为 2.5M, 其 GBR为 2M; 第二业务数据流的速率为 0.5M, 其 GBR为 1M, 则第一业务数据流的速率为 2.5M大于其 GBR, 则设置该第 一业务数据流的速率为 2M。 由于第二业务数据流的速率为 0.5M小于其 GBR, 则 第二业务数据流的速率依然为 0.5M。 此时, 由于承载的保证速率大于第一业务 数据流的速率和第二业务数据流的速率之和, 则可以提高第一业务数据流的速 率为 2.5M, 其小于第一业务数据流对应的 MBR, 且提高的第一业务数据流的速 率和第二业务数据流的速率之和等于承载的保证速率。 本发明实施例提供了一种业务^率控制方法和系统及设备, 以解决某些业 务数据流的速率由于业务特点, 会持续超过其本身的 GBR, 从而导致与其共用 同一承载的其他业务数据流的 QoS不能被满足的问题, 从而保证了用户的体验 度。

则该 PGW还可以进一步包括: 查询模块, 用于若该判断模块 22判断出不包 括特定指示标识, 或者包括特定指示标识, 且该特定指示标识为非新承载建立 的特定指示标识, 则查询是否存在与该 QCI和 ARP赋值相同的承载; 则该承载建 立模块 23还用于若该查询模块查询若存在与该 QCI和 ARP赋值相同的承载,则设 置与该 QCI和 ARP赋值相同的承载为第二承载。绑定模块 24还用于将该业务数据 流标识对应的业务数据流绑定在该第二承载上。
