相关申请的交叉引用
本申请主张在2017年10月27日在中国提交的中国专利申请号No.201711025535.4的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种丢包率计算方法、网络设备及终端。
背景技术
在第四代(4 th Generation，4G)移动通信系统，或称为长期演进(Long Term Evolution，LTE)系统的双连接(Dual Connectivity，DC)系统中，包括三种不同的承载类型，具体为：主小区群组(Master Cell Group，MCG)承载，分离(split)承载和辅小区群组(Secondary Cell Group，SCG)承载。在第五代(5 th Generation，5G)移动通信系统，或称为新空口(New Radio，NR)系统的DC架构中，不仅支持MCG和SCG，还进一步支持分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)复制功能，因此产生不同的承载类型(bear type)。具体的，5G系统的DC架构中支持的承载类型包括以下：
如图1所示，MCG承载，该承载对应PDCP、无线链路控制(Radio Link Control，RLC)和媒体接入控制(Medium Access Control，MAC)等实体的MCG。
如图1所示，SCG承载，该承载对应PDCP、RLC和MAC实体的SCG。
如图2所示，Split承载，该承载对应的PDCP实体在1个小区组，即该承载对应的PDCP实体均在MCG或SCG中，该承载对应的2个RLC实体和2个MAC实体分别在不同的小区组，即该承载对应的RLC实体或MAC实体一个在MCG中另一个在SCG中。
如图3所示，复制(Duplicate)承载，该承载对应的1个PDCP实体、2个RLC实体和1个MAC实体均在1个小区组，即该承载对应的1个PDCP 实体、2个RLC实体和1个MAC实体均在MCG或SCG中。
此外，为了网络设备能够更好地为配置相关的无线资源配置参数给终端，NR系统中的网络设备可以通过自行计算或通过终端上报的方式获取层2(Layer-2，L2)测量的结果。其中，网络设备自行计算的L2测量包括：物理资源块(Physical Resource Block，PRB)使用率(usage)、随机接入前导码(Received Random Access Preamble)、激活终端的数量(Number of active UEs)、下行数据包延迟率(Packet Delay)、丢包率(Data Loss)、调度的IP吞吐量(Scheduled IP Throughput)、调度的最小化路测(Minimization Drive Test，MDT)的IP吞吐量(Scheduled IP Throughput for MDT)、数据量(Data Volume)和共享网络数据量(Data Volume for Shared Networks)。终端上报的L2测量包括上行数据包延迟率(Packet Delay)。
此外，在5G系统中还增加了预处理功能，具体地，终端在未收到网络设备发送的上行发送授权时，可对数据进行预处理，生成对应的待发送数据包，如MAC层分组数据单元(Packet Data Unit，PDU)。
进一步地，在5G系统中引入了服务质量(Quality-of-Service，QoS)的网络设备侧指示机制，需要在上行和下行数据的发送过程中加入终端的IP数据流的QoS指示信息，如QoS流标识(QoS flow ID)。如图4所示，业务数据适配协议(Service Data Adaptation Protocol，SDAP)层位于PDCP层之上，1个SDAP实体对应1个PDU会话(PDU session)，1个SDAP实体对应多个数据无线承载(Data Radio Bearer，DRB)，即1个SDAP实体对应多个PDCP实体，网络设备为每个DRB配置相应的服务流(flow)。其中，服务数据单元(Service Data Unit，SDU)为某协议层从高层协议层接收的数据包，或向高层协议层发送的数据包，如MAC层从RLC层接收到的数据包称为MAC SDU。PDU为某协议层向低层协议层发送的数据包，或从低层协议层接收的数据包，如MAC层向物理层发送到的数据包称为MAC PDU。
由于引入了不同的承载类型、预处理功能以及新的协议SDAP层，采用传统系统中的丢包率计算方式，无法准确确定数据传输的丢包率。

针对因引入了不同的承载类型、预处理功能以及新的协议SDAP层而无法计算数据传输丢包率的问题，本公开实施例提供了一种丢包率计算方法、网络设备及终端。
如图5所示，本公开实施例的丢包率计算方法，应用于网络设备，具体包括步骤51至52。
步骤51：获取当前传输下的业务承载类型和数据包类型中的至少一项。
其中，业务承载类型为当前数据传输所属的承载类型，数据包类型为当前数据传输所属实体层的数据包类型。具体地，业务承载类型包括：MCG承载、SCG承载、split承载的MCG分支、split承载的SCG分支以及复制承载中的一项。进一步地，数据包类型用于指示不同实体层中的数据包，具体包括：业务数据适配协议SDAP实体中服务数据单元SDU的数据包、SDAP实体中分组数据单元PDU的数据包、分组数据汇聚协议PDCP实体中SDU的数据包(可用于没有SDAP实体的网络实体)、PDCP实体中PDU的数据包(可用于没有SDAP实体的网络实体)、无线链路控制RLC实体中SDU的数据包(可用于split承载没有PDCP实体的网络实体)、RLC实体中PDU的数据包(可用于split承载没有PDCP实体的网络实体)、媒体接入控制MAC实体中SDU的数据包(可用于split承载没有RLC实体的网络实体)和MAC实体中PDU的数据包(可用于split承载没有RLC实体的网络实体)中的至少一项。
步骤52：根据业务承载类型和数据包类型中的至少一项，确定当前传输下的丢包率。
这里指的是，网络设备可基于业务承载类型确定当前传输的丢包率，还可基于数据包类型确定当前传输的丢包率，还可基于数据包类型确定当前传输下不同业务承载类型下的丢包率。
在网络设备确定当前传输下的丢包率后，可根据该丢包率，为下一传输 配置传输资源及传输方式。
由于网络设备是基于不同业务承载类型和不同数据包类型中的至少一项确定当前传输的丢包率，因此可适用于5G系统中各个场景下的丢包率确定，而不受特定场景的限制，这样，网络设备基于该丢包率为下一传输配置相应的传输资源及传输方式更符合实际传输环境，例如将数据包在更好的传输路径上进行发送，或更改无线资源配置以降低丢包率，从而提高数据包发送的可靠性等。
可选地，步骤52包括：根据业务承载类型和数据包类型中的至少一项在特定时间区间内丢弃的数据包数量以及接收到的数据包数量，计算当前传输下在特定时间区间内的丢包率。其中，特定时间区间为丢包率的计算周期。
可选地，丢包率包括：特定终端的丢包率、基于服务质量级别标识(QoS Class Identifier，QCI)的丢包率、基于承载类型的丢包率、基于承载类型的发送路径的丢包率、基于承载的丢包率和基于服务质量QoS流的丢包率中的至少一项。即网络设备能够基于特定时间区间内不同业务承载类型或不同数据包类型下丢弃的数据包数量以及接收到的数据包数量，计算出针对某个终端的丢包率，或针对某个QCI的丢包率，或针对某种业务承载类型的丢包率，或针对某种业务承载类型的发送路径的丢包率，或针对某个承载的丢包率，或针对某个QoS flow的丢包率。
具体地，丢包率的类型包括：特定目标的丢包率以及与特定承载类型相关的丢包率中的至少一项。可选地，特定目标的丢包率包括：特定终端的丢包率、基于服务质量级别标识(QoS Class Identifier，QCI)的丢包率和基于服务质量QoS流的丢包率中的至少一项。与特定承载类型相关的丢包率包括：基于承载类型的丢包率、基于承载类型的发送路径的丢包率和基于承载的丢包率。其中值得指出的是，特定目标的丢包率可通过任意一个或任意多个不同类型的数据包进行计算，即特定目标的丢包率可通过不同实体层的不同数据包进行计算，例如：某个终端的丢包率可通过SDAP实体中SDU的数据包、SDAP实体中SDAP中PDU的数据包、PDCP实体中SDU的数据包、PDCP实体中PDU的数据包、RLC实体中SDU的数据包、RLC实体中PDU的数据包、MAC实体中SDU的数据包和MAC实体中PDU的数据包中的至少一 种数据包计算得到，值得指出的是，其他特定目标的丢包率亦可通过以上8种不同类型的数据包中的至少一种计算得到，故不在此赘述。同理，与某特定承载类型相关的丢包率亦可通过任意一个或任意多个不同类型的数据包进行计算，即与特定承载类型相关的丢包率可通过不同实体层的不同数据包进行计算，例如：某个承载类型(如MCG承载)的丢包率可通过SDAP实体中SDU的数据包、SDAP实体中SDAP中PDU的数据包、PDCP实体中SDU的数据包、PDCP实体中PDU的数据包、RLC实体中SDU的数据包、RLC实体中PDU的数据包、MAC实体中SDU的数据包和MAC实体中PDU的数据包中的至少一种数据包计算得到，值得指出的是，其他与承载类型相关的丢包率亦可通过以上8种不同类型的数据包中的至少一种计算得到，故不在此赘述。

进一步地，特定时间区间内从当前协议实体递交到高层协议实体时缺失的数据包的数量，根据当前协议实体在特定时间区间内递交到高层协议实体的总的数据包中丢失的序列号确定。即Ddisc(T,qci)可通过当前协议实体在特定时间区间内递交到高层协议实体的总的数据包中丢失的序列号确定，具体地，可通过统计当前协议实体在特定时间区间T内递交到高层协议实体的总的数据包中丢失的序列号确定，如“递交到高层协议实体的总的数据包”的编号范围为[1，10]，其中SN编号为5和6的序列号丢失，则判断“缺失的数据包”数量为2。
进一步地，特定时间区间内从当前协议实体递交到高层协议实体的总的数据包的数量，根据当前协议实体中数据包的序列号确定。即N(T,qci)可通 过当前协议实体中数据包的序列号确定，具体地，可通过统计当前协议实体的数据包序列号确定，如起始SN号1，最后SN号10，则总的数据包的数量为10。

以上实施例从网络设备侧介绍了本公开的丢包率计算方法，下面本实施例将结合附图对终端侧的丢包率计算方法做进一步介绍。
如图8所示，本公开实施例的丢包率计算方法，应用于终端，具体包括步骤81至83。
步骤81：接收网络设备发送的用于计算下行数据丢包率的业务承载类型和数据包类型中的至少一项。
这里是说终端根据网络设备的指示，确定业务承载类型和数据包类型。其中，业务承载类型为当前数据传输所属的承载类型，数据包类型为当前数据传输所属实体层的数据包类型。具体地，业务承载类型包括：MCG承载、SCG承载、split承载的MCG分支、split承载的SCG分支以及复制承载中的一项。进一步地，数据包类型用于指示不同实体层中的数据包，具体包括：业务数据适配协议SDAP实体中服务数据单元SDU的数据包、SDAP实体中 分组数据单元PDU的数据包、分组数据汇聚协议PDCP实体中SDU的数据包(可用于没有SDAP实体的网络实体)、PDCP实体中PDU的数据包(可用于没有SDAP实体的网络实体)、无线链路控制RLC实体中SDU的数据包(可用于split承载没有PDCP实体的网络实体)、RLC实体中PDU的数据包(可用于split承载没有PDCP实体的网络实体)、媒体接入控制MAC实体中SDU的数据包(可用于split承载没有RLC实体的网络实体)和MAC实体中PDU的数据包(可用于split承载没有RLC实体的网络实体)中的至少一项。
步骤82：根据业务承载类型和数据包类型中的至少一项，计算下行数据丢包率。
这里指的是，终端可基于业务承载类型确定当前传输的丢包率，还可基于数据包类型确定当前传输的丢包率，还可基于数据包类型确定当前传输下不同业务承载类型下的丢包率。可选地，这里所说的丢包率包括：特定终端的丢包率、基于服务质量级别标识QCI的丢包率、基于承载类型的丢包率、基于承载类型的发送路径的丢包率、基于承载的丢包率和基于服务质量QoS流的丢包率中的至少一项。

终端在计算得到下行数据丢包率后，将该下行数据丢包率发送至网络设备，以使网络设备进行下一次传输的传输资源配置和传输方式配置，以优化网络。
可选地，步骤82具体为：根据特定时间区间内不同业务承载类型或不同数据包类型下从当前协议实体递交到高层协议实体时缺失的数据包的数量和总的数据包的数量，计算特定时间区间内的下行数据丢包率。
其中，当前协议实体指的是5G系统中各协议层中的某一层的实体，具体地，当前协议实体为：SDAP实体、PDCP实体、RLC实体或MAC实体。高层协议实体指的是较当前协议实体更高层的实体。
具体地，终端可参照公式
Figure PCTCN2018104959-appb-000005
计算特定时间区间内的下行数据丢包率并上报至网络设备。
其中，其中，M(T，qci)表示在特定时间区间T内的下行数据丢包率； Ddisc(T,qci)表示时间区间T内不同业务承载类型或不同数据包类型下从当前协议实体递交到高层协议实体时缺失的数据包的数量；N(T,qci)表示特定时间区间T内不同业务承载类型或不同数据包类型下从当前协议实体递交到高层协议实体的总的数据包的数量。
进一步地，特定时间区间内从当前协议实体递交到高层协议实体时缺失的数据包的数量，根据当前协议实体在特定时间区间内递交到高层协议实体的总的数据包中丢失的序列号确定。即Ddisc(T,qci)可通过当前协议实体在特定时间区间内递交到高层协议实体的总的数据包中丢失的序列号确定，具体地，可通过统计当前协议实体在特定时间区间T内递交到高层协议实体的总的数据包中丢失的序列号确定，如“递交到高层协议实体的总的数据包”的编号范围为[1，10]，其中SN编号为5和6的序列号丢失，则判断“缺失的数据包”数量为2。
进一步地，特定时间区间内从当前协议实体递交到高层协议实体的总的数据包的数量，根据当前协议实体中数据包的序列号确定。即N(T,qci)可通过当前协议实体中数据包的序列号确定，具体地，可通过统计当前协议实体的数据包序列号确定，如起始SN号1，最后SN号10，则总的数据包的数量为10。
进一步地，在步骤83之前，该方法还包括：接收网络设备发送的与下行数据丢包率相关的配置信息。其中，配置信息包括：测量量标识、测量对象标识和触发上报配置中的至少一项。
可选地，上述测量量标识包括下行数据丢包率测量量标识。
上述测量对象标识包括：无线承载(Radio Bearer，RB)标识、服务质量QoS流标识、分离split承载的路径标识(如该承载对应路径的逻辑信道标识或小区组标识)、复制承载的路径标识(如该承载对应路径的逻辑信道标识)、小区群组标识(如MCG或SCG)和业务承载类型标识(如MCG承载、SCG承载、split承载或复制承载)中的至少一项。
其中，触发上报配置用于指示终端在满足何种条件时在何时上报。具体地，触发上报配置包括：周期性上报的配置、下行数据丢包率超过第一门限值上报的配置、下行数据丢包率低于第二门限值上报的配置、下行数据丢包 率超过第三门限值后周期性上报的配置和下行数据丢包率低于第四门限值后周期性上报的配置中的至少一项。其中，值得指出的是，第一门限值、第二门限值、第三门限值和第四门限值的具体取值可根据实际需要而定，且一般地，第一门限值大于第二门限值，第三门限值大于第四门限值。
可选地，触发上报配置中的各配置包括下行数据丢包率的计算时间窗口、下行数据丢包率的上报周期和下行数据丢包率的丢包率门限值中的至少一项，其中，下行数据丢包率的计算时间窗口为上述特定时间区间，其长度可根据实际需要进行设定，如设定为10ms，进一步地，该计算时间窗口的大小还可由协议预先定义。下行数据丢包率的门限值可指示各触发上报配置中的门限值，门限值具体为比例，如10％。下行数据丢包率的上报周期可指示各触发上报配置中的周期性上报的时间周期，如50ms。
具体地，由于触发上报配置用于触发终端的上报行为，当触发上报配置指示的上报条件不同时，终端的上报时机不同。下面本实施例将结合不同触发上报配置介绍终端的上报机制。
具体地，当触发上报配置包括周期性上报的配置时，步骤83为：按照配置信息中配置的周期，将下行数据丢包率发送至网络设备。例如网络设备指示终端周期性上报的周期为10ms，那么终端按照10ms的周期向网络设备发送自己计算得到的下行数据丢包率。
具体地，当触发上报配置包括下行数据丢包率超过第一门限值上报的配置时，步骤83为：根据配置信息进行测量，在测量到下行数据丢包率超过第一门限值时，将下行数据丢包率发送至网络设备。例如，网络设备指示下行数据丢包率高于10％时触发上报，那么终端在确定下行数据丢包率高于10％时，向网络设备发送下行数据丢包率，在确定下行数据丢包率低于10％时，不做上报处理。
具体地，当触发上报配置包括下行数据丢包率低于第二门限值上报的配置时，步骤83为：根据配置信息进行测量，在测量到下行数据丢包率低于第二门限值时，将下行数据丢包率发送至网络设备。例如，网络设备指示下行数据丢包率低于5％时触发上报，那么终端在确定下行数据丢包率低于5％时，向网络设备发送下行数据丢包率，在确定下行数据丢包率高于5％时，不做上 报处理。
其中，值得指出的时，若网络设备同时指示了下行数据丢包率低于5％和下行数据丢包率高于10％时触发上报，那么终端在确定下行数据丢包率低于5％或确定下行数据丢包率高于10％时，向网络设备发送下行数据丢包率，在确定下行数据丢包率高于5％且低于10％时，不做上报处理。
具体地，当触发上报配置包括下行数据丢包率超过第三门限值后周期性上报的配置时，步骤83为：根据配置信息进行测量，在测量到下行数据丢包率超过第三门限值时，按照配置信息中配置的周期，将下行数据丢包率发送至网络设备。例如，网络设备指示下行数据丢包率高于10％时按照10ms为周期进行上报，那么终端在确定下行数据丢包率高于10％时，按照10ms为周期向网络设备发送下行数据丢包率，在确定下行数据丢包率低于10％时，不做上报处理。
具体地，当触发上报配置包括下行数据丢包率低于第四门限值后周期性上报的配置时，步骤83为：根据配置信息进行测量，在测量到下行数据丢包率低于第四门限值时，按照配置信息中配置的周期，将下行数据丢包率发送至网络设备。例如，网络设备指示下行数据丢包率低于5％时按照10ms为周期进行上报，那么终端在确定下行数据丢包率低于5％时，按照10ms的周期向网络设备发送下行数据丢包率，在确定下行数据丢包率高于5％时，不做上报处理。
其中，值得指出的时，若网络设备同时指示了下行数据丢包率低于5％和下行数据丢包率高于10％时按照10ms为周期进行上报，那么终端在确定下行数据丢包率低于5％或确定下行数据丢包率高于10％时，按照10ms为周期向网络设备发送下行数据丢包率，在确定下行数据丢包率高于5％且低于10％时，不做上报处理。其中，值得指出的是，上述触发上报配置中不同的上报配置只要不发生上报冲突均可进行任意组合。
本公开实施例的丢包率计算方法中，终端接收网络设备发送的业务承载类型和数据包类型中的至少一项，从而根据业务承载类型和数据包类型中的至少一项计算丢包率，可适用于5G系统中的各种应用场景，从而保证计算得到5G系统中精确的丢包率，进而将该丢包率发送至网络设备，以使得网 络设备为下一传输配置优化的传输资源及传输方式，如将数据包在更好的传输路径上进行发送，或更改无线资源配置以降低丢包率，从而提高数据包发送的可靠性等。
