具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合具体实施例及附图进行详细描述。
为使本领域技术人员能够更好地理解本公开实施例的技术方案,下面先对CP/UP分离的架构及层二(L2)统计量进行说明。
(1)CU/DU分离基站
5G基站(gNB)在集中式架构的基础上,还支持CU/DU分离,以及CP/UP分离的基站架构。集中式架构的空口协议栈,如图1所示,CU/DU分离结构的空口协议栈,如图2所示。在分离架构下,一个CU可以连接一个或多个DU。
CP/UP分离的结构,是在CU/DU分离架构的基础上,进一步将CU分离为CP与UP。其中,一个CU-CP可以连接到多个CU-UP,CU-CP与CU-UP之间采用E1接口。CU-CP与DU之间采用F1-C接口,而CU-UP与DU之间采用F1-U接口。
CU-CP管理gNB-CU的控制面,包括PDCP的控制面部分与RRC;CU-UP管理gNB-CU的用户面,包括PDCP的用户面部分与SDAP。CP/UP分离时,协议栈如图3所示。
(2)L2统计量
(2.1)涉及DU与CU-UP的L2统计量
涉及DU与CU-UP的统计量可能包含以下至少一项:
下行激活UE数量;
下行数据包时延;
下行数据包丢弃率;
下行丢包率;
上下行调度IP吞吐量;
上述各L2统计量统计需要使用MAC层、无线链路控制RLC或PDCP层的输入,才能完成统计量的计算,可能为每个终端(per UE),每个数据无线承载(per DRB)或者每个标度值(per QCI)的统计。
以下以数据包时延以及下行分QCI激活UE数量统计举例,说明L2统计量在集中式基站的统计方式。
a.数据包时延
基站需要统计并上报L2数据包时延,用于操作维护管理(Operation Administration and Maintenance,OAM)确定用户的下行数据包传输时延是否与预设的服务质量(Quality of Service,QoS)指标一致。
L2数据包时延的定义如下:
基于每一个QCI统计数据包的下行时延,统计针对DRB进行。对于每一个下行的数据包,当其到达基站的PDCP时开始计时,当基站MAC层收到对该数据包的确认正确接收时停止计时,这样就得到了该数据包的L2时延。统计一段时间内的所有数据包的平均时延,即为L2数据包时延。其计算公式如下:

公式中各参数的含义如表1所示:

上行丢包率;
上下行数据量;
上述各L2统计量统计仅需要在PDCP层进行处理,就可完成统计量的计算,可能为per UE,per DRB或者per QCI的统计。
以下以上行数据量统计以及上行丢包率举例,说明L2统计量在集中式基站的统计方式。
a.上行数据量统计
在一定时间周期内,基站成功接收到的PDCP SDU bits数量。
b.上行丢包率
该统计量用于OAM或者MDT目的的统计在上行传输过程中数据包丢失的比率。
Per QCI的统计,一个DRB对应一个PDCP SDU,参考点为PDCP的上端SAP。
公式定义如下:

本公开的实施例提供了一种层二统计量的发送方法,应用于统计节点,该统计节点为中心节点用户面CU-UP、分布式节点DU或者中心节点控制面CU-CP,如图4所示,该发送方法包括:
步骤101:中心节点用户面CU-UP、分布式节点DU或者中心节点控制面CU-CP获取层二统计量。
该层二统计量是根据层二(L2)统计量的输入参数计算得到的,L2统计量的输入参数包括CU-UP记录的第一输入参数和DU记录的第二输入参数中的至少一项。
在本公开的具体实施例中,在L2统计量为分别与DU和CU相关的统计量时,DU、CU-UP或CU-CP获取所述第一输入参数和所述第二输入参数,其中,所述CU包括所述CU-CP和CU-UP;
在所述L2统计量为UP相关的统计量时,UP获取所述第二输入参数;
在所述L2统计量为DU相关的统计量时,DU获取所述第一输入参数。
其中,上述第一输入参数包括下行数据包的发送时间、上行数据包的接收时间、上行缓存buffer信息、下行buffer信息中的至少一项;
上述第二输入参数包括下行数据包的到达时间、上行数据包解码完成时间、上行buffer信息、下行buffer信息、周期时长内的数据包个数、周期时长内的包数据量中的至少一项。
步骤102:向统计量收集节点发送所述层二统计量。
在本公开的具体实施例中,可由CU-UP、DU或者CU-CP向统计量收集节点发送上述层二统计量。
本公开实施例的层二统计量的发送方法,中心节点用户面CU-UP、分布式节点DU或者中心节点控制面CU-CP获取层二统计量;向统计量收集节点 发送所述层二统计量,实现了CP/UP分离的架构下,获取L2统计量并传输的目的。
作为第一种可选的实现方式,上述步骤101中中心节点用户面CU-UP获取层二统计量,包括:
CU-UP接收DU发送的第一输入参数,并根据所述第一输入参数和CU-UP自身记录的第二输入参数,获取层二统计量;
或者,CU-UP根据自身记录的第二输入参数,获取层二统计量。
基于此,上述步骤102包括:
CU-UP直接向统计量收集节点发送所述层二统计量;
或者,CU-UP将所述层二统计量发送给CU-CP,由CU-CP将所述层二统计量发送给统计量收集节点。
在本公开的具体实施例中,针对所有在CU-UP以及DU两侧才可以得到全部统计量输入参数的L2统计内容:当DU记录完成统计量输入参数后,可以发送给CU-UP,由CU-UP根据DU的输入与CU-UP自身记录的统计量输入参数一起进行统计量的计算,并将计算结果经由CU-CP或者由CU-UP自行发送给统计量收集节点。
以下行分QCI激活UE数量统计为例,该L2统计量需要的统计输入参数有:N(i,qci),I(T,p)。对应的参数含义可以参见协议36.314或者前述表格。
CU-UP对收到的下行数据包进行统计:对于每一个下行的数据包,当其到达CU-UP的SDAP/PDCP时,CU-UP记录该数据包的到达时间。
DU对收到的下行数据包进行统计:对于每一个下行的数据包,记录该数据包从DU侧缓存中清除的时刻,并向CU发送反馈信息,反馈信息中包括:记录的时间点,以及所对应的数据包的编号。
CU-UP结合数据包到达CU-UP的时刻,可以确定每一个下行数据包在接入网中的存续时间。对于任何一次采样时刻,CU-UP可以判断任何一个UE的任何一个DRB是否有下行数据包在接入网中存在。如果有数据包存在,则该DRB对应的QCI的下行激活UE数加1;否则,下行激活UE数不变。
CU-UP可以将所统计的结果上报CU-CP,由CU-CP发送给统计量收集节点,或者直接由CU-UP上报给统计量收集节点。
在本公开的具体实施例中,针对所有在CU-UP可以得到所有统计量输入参数的L2统计内容:当CU-UP记录完成统计量输入参数后,可以发送给CU-CP,由CU-CP进行统计量的计算,并将计算结果发送给统计量收集节点;或者,当CU-UP记录完成统计量收入参数后,自行计算统计量结果,经由CU-CP发送给统计量收集节点,或者由CU-UP直接上报给统计量收集节点。
以上行丢包率为例,该L2统计量需要的统计输入参数有:Dloss(T,qci),N(T,qci),T。对应的参数含义可以参见协议36.314或者前述表格。
基站的CU-UP可以统计在时间长度T之内,总的上行数据包PDCP SN数,以及丢失的上行数据包PDCP SN数。
当统计时间T结束之后,可以:
将Dloss(T,qci),N(T,qci),T按照公式计算,得到统计量结果M(T,qci),经由CU-CP发送给统计量收集节点,或者由CU-UP直接上报给统计量收集节点;
或者,在CU-UP不执行计算功能,将Dloss(T,qci),N(T,qci),T直接发送给CU-CP,由CU-CP按照公式进行统计量的计算,再将计算结果发送给统计量收集节点。
作为第二种可选的实现方式,上述步骤101中分布式节点DU获取层二统计量,包括:

或者,DU将所述层二统计量发送给CU-CP,由CU-CP将所述层二统计量发送给统计量收集节点。
在本公开的具体实施例中,针对所有在CU-UP以及DU两侧才可以得到全部统计量输入参数的L2统计内容:当CU-UP记录完成统计量输入参数后,可以发送给DU,由DU根据CU-UP的输入与DU自身记录的统计量输入参数一起进行统计量的计算,并将计算结果经由CU-CP或者由DU自行发送给 统计量收集节点。
以下行数据包时延为例,该L2统计量需要的统计输入参数有:tArriv(i),tAck(i),I(T)。对应的参数含义可以参见协议36.314或者前述表格。
基站的CU-UP可以在统计时间长度T之内,对收到的下行数据包标记时间戳:对于每一个下行的数据包,当其到达CU-UP的SDAP/PDCP时,CU-UP将当前时间与该数据包关联。该时间将作为时间戳与对应的下行数据包一起被发送到DU。
DU对收到的下行数据包进行统计:对于收到的来自CU-UP的每一个下行的数据包,DU记录其时间戳,当DU MAC层收到反馈确认该数据包的正确接收时,DU用当前时间减去对应时间戳所记录的时间,这样就得到了该数据包的全部L2数据包时延。统计一段时间(T)内的所有数据包的平均时延,即为L2数据包时延。
DU可以将所统计的结果上报CU-CP,由CU-CP发送给统计量收集节点,或者直接由DU上报给统计量收集节点。
在本公开的具体实施例中,针对所有在DU可以得到所有统计量输入参数的L2统计内容:当DU记录完成统计量输入参数后,可以发送给CU-CP,由CU-CP进行统计量的计算,并将计算结果发送给统计量收集节点;或者,当DU记录完成统计量收入参数后,自行计算统计量结果,经由CU-CP发送给统计量收集节点。
以上行PRB占用率为例,该L2统计量需要的统计输入参数有M1(T),P(T),T。对应的参数含义可以参见协议36.314或者前述表格。
基站的MAC(属于DU)可以统计在时间长度T之内可用的PRB总数,以及上行所有分配的用于传输的PRB。
当统计时间T结束之后,可以:
将M1(T),P(T),T按照公式计算,得到统计量结果M(T),经由CU-CP发送给统计量收集节点;
或者,在DU不执行计算功能,将M1(T),P(T),T直接发送给CU-CP,由CU-CP按照公式进行统计量的计算,再将计算结果发送给统计量收集节点。
作为第三种可选的实现方式,上述步骤101中心节点控制面CU-CP获取 层二统计量,包括:
CU-CP接收DU记录的第一输入参数和CU-UP记录的第二输入参数,并根据所述第一输入参数和所述第二输入参数,获取层二统计量;
或者,CU-CP接收DU记录的第一输入参数,并根据所述第一输入参数,获取层二统计量;
或者,CU-CP接收CU-UP记录的第二输入参数,并根据所述第二输入参数,获取层二统计量。
基于此,上述步骤102包括:
CU-CP向统计量收集节点发送所述层二统计量。
在本公开的具体实施例中,针对所有在CU-UP以及DU两侧才可以得到全部统计量输入参数的L2统计内容:当DU记录完成统计量输入参数后,可以发送给CU-CP;当CU-UP记录完成统计量输入参数后,发送给CU-CP。由CU-CP根据来自DU以及CU-UP的统计量输入参数一起进行统计量的计算,并将计算结果发送给统计量收集节点。
以下行分QCI激活UE数量统计为例,该L2统计量需要的统计输入参数有:N(i,qci),I(T,p)。对应的参数含义可以参见协议36.314或者前述表格。
CU-UP对收到的下行数据包进行统计:对于每一个下行的数据包,当其到达CU-UP的SDAP或PDCP时,CU-UP记录该数据包的到达时间,并向CU-CP发送记录信息,包括:记录的时间点,以及所对应的数据包的编号;
DU对收到的下行数据包进行统计:对于每一个下行的数据包,记录该数据包从DU侧缓存中清除的时刻,并向CU-CP发送该记录信息,包括:记录的时间点,以及所对应的数据包的编号。
CU-CP结合来自CU-UP以及DU的统计量输入信息,可以确定每一个下行数据包在接入网中的存续时间。对于任何一次采样时刻,CU-CP可以判断任何一个UE的任何一个DRB是否有下行数据包在接入网中存在。如果有数据包存在,则该DRB对应的QCI的下行激活UE数加1;否则,下行激活UE数不变。
CU-CP将计算得到的L2统计量结果发送给统计量收集节点。
