Description

一种上报网络性能参数的方法及设备
本申请要求在2017年8月11日提交中国专利局、申请号为201710685419.9、发明名称为《一种上报网络性能参数的方法及设备》的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种上报网络性能参数的方法及设备。
背景技术
网管网元可以创建关于网络性能参数的测量任务，并将任务下发给基站。基站根据测量任务中的配置要求将用于表征网络性能的参数上报给网管网元。网管网元根据基站上报的参数对网络进行监测和评估。用于表征网络性能的参数可以包括物理资源块利用率(PRB Usage)、空口传输速率等。物理资源块利用率是度量基站空口资源的指标，空口传输速率的高低直接影响着用户体验。
由于长期演进(long term evolution，LTE)网络是自干扰系统，若PRB Usage过高，会导致频谱效率降低，运营商流量增速下降。因此网管网元可以监测各小区的PRB Usage，以帮助运营商和设备商及时发现网络资源受限、用户负载过高的问题。
空口传输速率会随着终端的位置变化以及信道质量的波动而改变，网管网元可以通过监测各终端的空口传输速率，来避免空口传输速率过低造成用户体验不佳。
在现有技术中，网管网元建立的关于PRB Usage、空口传输速率的测量任务，通常要求基站按照分钟或小时级的上报周期(例如5分钟、15分钟、30分钟、1小时等)上报PRB Usage和空口传输速率在一个上报周期内的平均值。然而，在很多场景下，会出现短时的业务突发现象或信道质量波动的现象，导致PRB Usage在短时间较高、资源受限，或者空口传输速率较低。而基站上报的平均值无法反映出这些短时突发现象，不利于网管网元对网络性能的评估。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
运维支撑系统(the office of strategic services，OSS)可以创建测量任务，并将测量任 务下发给基站，基站对测量任务中配置的测量量进行测量，并将测量结果上报给OSS。
例如，测量任务中配置的测量量为物理资源块利用率时，基站获取周期T内物理资源块利用率平均值，并将该平均值上报给OSS，OSS根据基站上报的平均值对网络性能进行评估。
然而，在实际应用时，周期T通常取5分钟、15分钟或30分钟甚至更长，因此，周期T内物理资源块利用率的平均值，虽然能够表示周期T物理资源块利用率的整体情况，但是对于短时间的突发状况，例如由于较多数量的终端与基站同时进行通信导致物理资源块利用率突然上升到较大值，但是由于周期T内其他时刻的物理资源块利用率整体较低，使得在求取平均值后数值仍然较低，无法体现突发时刻的情况。
又例如，当测量任务中配置的测量量为空口传输速率时，也存在类似的问题。
由于基站上报的测量参数仅能够反映网络性能的整体性，无法反映突发状况。因此，OSS在根据基站上报的测量参数对网络性能进行评估时，可能存在评估结果不准确的情况，进而不能对网络进行有效的调控。
为了解决上述问题，本申请提供了一种上报网络性能参数的方法，用于实现上报的网络性能参数既能够反映出相应时间段内网络性能的整体性，又能反映网络性能的突发性。
在本申请实施例中，第一网络设备表示用于上报网络性能参数的设备，例如基站等；第二网络设备表示用于接收网络性能参数的设备，例如OSS等网管设备。
参见图1，为本申请提供的上报网络性能参数方法的流程示意图，如图所示，该方法可以包括以下步骤：
步骤101、第一网络设备获取采样信息、上报信息以及预设的至少一个参数值区间的信息。
其中，采样信息可以是用于指示采样周期的信息。具体地，采样信息可以是采样周期；或者，由于采样周期与采样频率之间存在既定的数学关系，因此采样信息也可以是采样频率。第一网络设备根据采样周期进行采样。
上报信息可以是用于指示上报周期的信息，上报周期通常为采样周期的N倍，N为大于等于1的整数。具体地，上报信息可以是上报周期，或者，也可以是上报频率，或者还可以是N的取值，第一网络设备可以根据采样周期和N的取值确定出上报周期。第一网络设备根据上报周期，将采集到的第一参数信息或者经过处理后的第一参数信息上报给第二网络设备。
例如，采样信息指示采样周期为1秒，上报信息指示上报周期为5分钟，那么N为300，第一网络设备每1秒获取一个第一参数信息，每5分钟对获取到的300个第一参数信息进行处理，并将处理结果上报给第二网络设备。
预设的至少一个参数值区间的信息，用于指示每个参数值区间对应的参数值范围。
在一个具体实施例中，若每个参数值区间的宽度相同，那么参数值区间的信息可以为每个参数值区间的宽度，例如，第一参数为物理资源块利用率，预设的参数值区间分别为[0％，20％]、(20％，40％]、(40％，60％]、(60％，80％]以及(81％，100％]，如图2所示。由于每个区间的宽度均为20％，因此，参数值区间的信息可以为20％，那么第一网络设备则可以对物理资源块利用率的取值范围进行等分，且等分后每个区间的宽度为20％，以获得上述每个参数值区间的范围。
在另外一些实施例中，参数值区间的信息也可以是每个区间的取值范围，比如，当多 个参数值区间的宽度不同时，参数值区间的信息可以包括每个区间的取值范围。举一个具体的例子，第一参数为空口传输速率，由于传输速率大多时候集中在0～1Mbps之间，那么划分的参数值区间可以分别为[0,1]、(1,5]、(5,10]、(10,15]、(15,20]、(20,+∞](单位Mbps)，如图3所示。
若划分的参数值区间的数量较多，则能够更精准的反映出参数值的分布、变化，然而，由于参数值区间较多，第一网络设备统计量增加，上报的内容信息也相应增加；若划分的参数值区间的数量较少，则第一网络设备的统计量减少，上报的内容信息也相应减少，但有可能无法精准反映出在周期T内参数值的整体性和突发性。因此，在对参数值区间进行划分时，可以参考已经采集到的多个第一参数的取值范围，以及网络性能较好或较差时第一参数的取值范围。
以第一参数为物理资源块利用率为例，那么第一参数的取值范围为[0，100％]，可以对第一参数的取值范围进行若干等分，例如，等分的5个参数值区间分别为[0％，20％]、(20％，40％]、(40％，60％]、(60％，80％]以及(81％，100％]；或者，还可以结合第一参数的取值与网络性能之间的对应关系进行区间划分，例如，划分后的参数值区间分别为[0％，20％]、(20％，70％]以及(70％，100％]，其中，若第一参数的值落在(70％，100％]区间内，则说明此时物理资源块利用率较高，网络负荷较大，若第一参数的值落在(20％，70％]区间内，则说明此时物理资源块利用率较为适中，网络负荷适中，若第一参数的值落在[0％，20％]区间内，说明此时物理资源块利用率较低，大量物理资源被闲置。
应当理解，上述参数值区间的数量、每个参数值区间的取值范围均为举例说明，本申请对此不做限制。
在一种可能的实现方式中，上述采样信息、上报信息、至少一个参数值区间的信息，在这三者中至少一个是预设信息。第一网络设备的存储器中可以预先存储有采样信息、上报信息、至少一个参数值区间的信息中的一种或多种。例如，在未来的通信协议中可以对采样周期、上报周期和预设的至少一个参数值区间的信息进行限定，那么第一网络设备的存储器中则预先存储有采样周期、上报周期以及预设的至少一个参数值区间的信息，第一网络设备可以从存储器读取采样周期、上报周期以及预设的至少一个参数值区间的信息。
在另外一种可能的实现方式中，上述采样信息、上报周期、预设的至少一个参数值区间的信息，在这三者中至少一个是由是第二网络设备发送给第一网络设备的。例如，第二网络设备在创建测量任务时，可以根据实际需求确定第一网络设备的采样周期、上报周期以及第一参数的参数值区间如何划分，并将这些信息携带在测量任务中下发给第一网络设备，第一网络设备根据第二网络设备下发的测量任务确定采样周期以及参数值区间的信息。
可选地，还可以对上述两种实现方式进行结合，即对采样信息、上报信息或预设的至少一个参数值区间的信息，预先约定默认值，若第二网络设备向第一网络设备发送了采样信息、上报信息或参数值区间的信息，则第一网络设备根据第二网络设备发送的采样信息、上报信息或参数值区间的信息确定采样周期、上报周期以及每个参数值区间的范围；若第二网络设备没有向第一网络设备发送采样信息、上报信息或参数值区间的信息，则第一网络设备根据预先约定的默认值，确定采样周期、上报周期以及每个参数值区间的范围。
步骤102、第一网络设备分别在N个采样周期中进行采样，得到N个第一参数信息。
在一种可能的实现方式中，第一网络设备在每个采样周期中进行采样时，可以在该周 期内某个时刻上进行采样，根据该时刻采样得到的参数确定该采样周期的第一参数信息。
具体地，可以根据公式(1)进行计算得到与该采样周期对应的物理资源块利用率：
Figure PCTCN2018100074-appb-000005
其中，M表示一个采样周期内的上行(或下行、或上行和下行)物理资源块利用率，M1表示上行传输(或下行传输，或上行传输和下行传输)中所使用的物理资源块的数量，P表示所有可用于上行传输(或下行传输，或上行传输和下行传输)的物理资源块的数量。
为了统计方便，公式(1)采用了向下取整的算法，应当理解，公式(1)中的向下取整也可以变换为向上取整。
再例如，在一个采样周期内，共传输了L个数据包，L为大于等于1的整数，第一网络设备获取每个数据包的数据量ThpVolDl(i)以及每个数据包的传输时长ThpTimeDl(i)，然后根据下述公式确定该周期的空口传输速率Ipthroughput：
Figure PCTCN2018100074-appb-000006
其中，i为大于等于1且小于等于L的整数。
通常，每个数据包的数据量的单位为千比特(kbits)，每个数据包的传输时长的单位为ms，空口传输速率可以在公式(2)的基础上再乘以1000，将空口传输速率的单位转换为kbits/s，以符合应用习惯。
此外，由于通常每个数据包的传输时长的单位为ms，即一个时间传输间隔(TTI)，而在计算一个数据包的传输时长时，可以通过传输结束的时间减去传输开始的时间获得，因此，若一个较小数据包在一个TTI内完成了传输，那么传输结束的时间减去传输开始的时间即为0。若一个采样周期内每个数据包均在一个TTI内完成传输，即若公式(2)中分母上的值为0时，那么则认为该采样周期上的空口传输速率为0。
在另外一种可能的实现方式中，第一网络设备还可以在采样周期内进行多次采样，并根据多次采样结果确定该周期内的第一参数信息。例如，将采样周期进一步划分为k个采样子周期，第一网络设备在k个采样子周期上进行采样，并根据公式(1)得到每个采样子周期的物理资源块利用率，或者根据公式(2)得到每个采样子周期的空口传输速率，然后对k个子周期的物理资源块利用率或空口传输速率求取平均值，得到该采样周期内的物理资源块利用率或空口传输速率。
步骤103、第一网络设备确定上述N个第一参数在上述至少一个参数值区间内的分布情况信息。
在一种可能的实现方式中，第一网络设备针对上述至少一个参数值区间，确定得到所述N个第一参数分别落入每个参数值区间的数量。
仍以第一参数为物理资源块利用率、参数值区间分别为[0％，20％]、(20％，40％]、(40％，60％]、(60％，80％]以及(81％，100％]为例，第一网络设备针对每个区间，确定落入该区间内的第一参数的数量，上述5个参数值区间分别对应的第一参数的数量为n 1、n 2、n 3、n 4以及n 5，其中，n 1、n 2、n 3、n 4以及n 5均为大于等于0的整数，且n 1+n 2+n 3+n 4+n 5＝N，具体可如图2所示。
在另外一种可能的实现方式中，第一网络设备针对每个参数值区间，确定得到N个第一参数分别落入每个参数值区间的数量，并进一步确定每个参数值区间对应的第一参数的数量与N的比值。
仍以第一参数为物理资源块利用率、参数值区间分别为[0％，20％]、(20％，40％]、(40％，60％]、(60％，80％]以及(81％，100％]为例，第一网络设备针对每个区间，确定落入该区间内的第一参数的数量，上述5个参数值区间分别对应的第一参数的数量为n 1、n 2、n 3、n 4以及n 5，其中，n 1、n 2、n 3、n 4以及n 5均为大于等于0的整数，且n 1+n 2+n 3+n 4+n 5＝N。然后第一网络设备进一步确定n 1与N的比值、n 2与N的比值、n 3与N的比值、n 4与N的比值、以及n 5与N的比值。
步骤104、第一网络设备将确定出的分布情况信息发送给第二网络设备。
如前所述，若第一网络设备确定出的分布情况信息为每个参数值区间对应的第一参数的数量，那么第一网络设备则将每个参数值区间对应的第一参数的数量上报给第二网络设备，例如，第一网络设备可以将[n 1，n 2，n 3，n 4，n 5]发送给第二网络设备。
举例说明，假设上报周期为5分钟，采样周期为1秒，那么N＝300，即每个参数值区间对应的第一参数的数量最大为300，可用9个比特位表示，若按照上述共划分5个参数值区间的情况，那么第一网络设备在一个上报周期内上报的分布情况信息可以用45个比特位表示，信令开销、资源开销并不大。
若第一网络设备确定出的分布情况信息为每个参数值区间所对应的第一参数的数量与N的比值，那么第一网络设备则将每个参数值区间所对应的第一参数的数量与N的比值上报给第二网络设备，例如，第一网络设备可以将[n 1/N，n 2/N，n 3/N，n 4/N，n 5/N]发送给第二网络设备。
与现有技术中仅将平均值上报给第二网络设备相比，将每个参数值区间对应的第一参数的数量上报给第二网络设备，或者，将每个参数值区间所对应的第一参数的数量与N的比值上报给第二网络设备，有助于第二网络设备可以更全面了解该N个采样周期中网络性能的情况，对于该N个采样周期对应的时间段内发生的突发状况，也不会由于求取平均值而无法体现。
第二网络设备在接收到第一网络设备发送的分布情况信息之后，可以对该N个采样周期内网络性能的整体情况进行分析，例如，分析该N个采样周期内第一参数分布数量最多的参数值区间；也可以对该N个采样周期内的突发情况进行分析，例如，分析数值较大或较小的参数值区间对应的第一参数的数量。
在上述方法中，预先对第一参数的取值范围进行区间划分，第一网络设备按照预设的采样周期进行采样，并将N个采样周期在预设区间的分布情况信息上报给第二网络设备，以使第二网络设备根据所述分布情况信息对网络性能进行评估。由于第一参数在预设区间上的分布情况信息，比现有技术中上报的平均值更能反映出N个采样周期内网络性能的整体性和突发性，有助于第二网络设备根据分布情况信息进行网络性能评估时，得到更加准确的网络性能评估结果。
此外，为了解决上述技术问题，本申请还提供了一种上报网络性能参数的方法，用于实现上报的网络性能参数既能够反映出相应时间段内网络性能的整体性，又能反映网络性能的突发性。
参见图4，为本申请提供的上报网络性能参数方法的流程示意图，如图所示，该方法可以包括以下步骤：
步骤401、第一网络设备获取采样信息和上报信息中的至少一种。
其中，采样信息用于指示采样周期，上报信息用于指示上报周期，且上报周期为采样周期的N倍，N为大于等于1的整数。在一个具体的实施例中，上报信息也可以是N的取值，第一网络设备可以根据采样周期和N的取值，进一步确定出上报周期。
在一种可能的实现方式中，上述采样信息和上报信息，至少一个是预设信息。例如，在未来的通信协议可以对采样周期和上报周期进行限定，那么第一网络设备的存储器中可能预先存储有采样周期以及上报周期，第一网络设备可以从存储器中读取采样周期以及上报周期。
在另外一种可能的实现方式中，上述采样信息和上报信息，至少一个是由第二网络设备发送给第一网络设备的。例如，第二网络设备在创建测量任务时，可以根据实际需求确定第一网络设备的采样周期以及上报周期，并将这些信息携带在测量任务中下发给第一网络设备，第一网络设备根据第二网络设备下发的测量任务确定采样周期以及上报周期。
可选地，还可以对上述两种实现方式进行结合，即第一网络设备的存储器中预先存储有采样信息和上报信息的默认值，若第二网络设备向第一网络设备发送了采样信息或上报信息，则第一网络设备根据第二网络设备发送的采样信息或上报信息确定采样周期、上报周期以及每个参数值区间的范围；若第二网络设备没有向第一网络设备发送采样信息、上报信息，则第一网络设备根据预存的默认值，确定采样周期、上报周期。
步骤402、第一网络设备分别在上报周期包括的N个采样周期中进行采样，得到N个第一参数信息。
在一种可能的实现方式中，第一网络设备在每个采样周期中进行采样时，可以在该采样周期内某个时刻上进行采样，根据该时刻采样得到的参数确定该采样周期的第一参数信息。
在另外一种可能的实现方式中，第一网络设备还可以在该采样周期内进行多次采样，并将多次采样结果确定该采样周期内的第一参数信息。
具体实现方式与步骤102中的实现方式类似，此处不再一一赘述。
步骤403、第一网络设备将上述N个第一参数信息发送给第二网络设备。
第二网络设备在接收到第一网络设备发送的N个第一参数信息之后，可以对该N个采样周期内网络性能的整体情况进行分析，例如，第二网络设备可以统计该N个第一参数的平均值；也可以对该N个采样周期内的突发情况进行分析，例如，第二网络设备可以统计该N个第一参数中数值较大或较小的参数的数量及分布。
在上述方法中，第一网络设备分别在一个上报周期中的N个采样周期中进行采样得到N个第一参数信息，并将该N个第一参数信息上报给第二网络设备，以使第二网络设备根据该N个第一参数对网络性能进行评估，比现有技术中上报的平均值更能反映出N个采样周期内网络性能的整体性和突发性，第二网络设备可以获取到更多的关于网络性能的信息，有助于第二网络设备在进行网络性能评估时，得到更加准确的网络性能评估结果。
