确定网络切片可用资源的方法、电子设备和存储介质
相关申请
本申请要求于2021年11月17日申请的、申请号为202111361540.9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
本申请实施例涉及无线通信技术领域，特别涉及一种确定网络切片可用资源的方法、电子设备和存储介质。
背景技术
当前，行业数字化席卷全球，能源、工业制造、港口、交通等不同行业都在积极探索数字化转型。在数据传输环节，5G技术以其特有的移动性、高带宽、低时延高可靠、广连接等优势，有望成为支撑行业应用的重要基础设施。服务于企业用户(To Business，ToB)的垂直行业千差万别，对通信网络的需求也多种多样，在时延、可靠性、速率、自服务能力等方面与传统服务于普通移动终端用户(To Customer，ToC)的领域有较大的差异，对5G网络带来的挑战主要体现在如下方面：
(1)时延和可靠性
行业的一些高精尖业务要求网络端到端时延<12ms，可靠性≥99.999％，例如智能电网的差动保护，工业的实时控制等。
(2)速率
行业应用的数据传输主要使用网络的上行链路，例如工业领域的机器视觉和港口的远程岸桥类应用，主要传输图片流和视频流，提出了单用户上行速率100Mbps，甚至更高的要求。
通过网络切片将运营商网络进行逻辑划分，把一个物理网络虚化出多个逻辑上的虚拟网络，每个切片可配置不同的资源比例，如图1所示，为每个切片组分配了不同比例的专用资源。不同等级的业务数据可以在不同逻辑层面的网络切片上传输，从而可以满足不同业务场景对网络的数据传输速率、安全性、可靠性等多方面的差异化需求。当采用切片的建网方式时，网规网优工程师需根据切片的业务需求(带宽、可靠性)，进行切片物理资源块(Physical Resource Block，PRB)资源分配的相关网管参数配置；同时，行业用户也需要根据业务应用需求，进行租赁资源估算。
目前的运营商网络在PRB资源估算方面，一种方式，主要考虑的是小区级的资源估算，典型的处理方法是通过系统仿真的方式进行单小区频谱效率的仿真，根据载波带宽计算单小区的吞吐率能力。然而，采用这种方式进行资源估算时，未考虑到终端级的资源消耗需求，以及业务可靠性的需求，无法满足ToB切片业务的实际需求。另一种方式，是通过网规仿真的方式估算某个栅格的调制与编码策略(Modulation and Coding Scheme，MCS)，需要对发射端到接收端的每个环节上都进行准确的预估，涉及的环节包括：站点工程参数、电子地图、传播模型，以及基于Massive MIMO业务信道赋形的精准建模，前提 条件过多；这种方式虽然考虑了终端的资源消耗需求，但在实际应用中存在诸多限制，也很难保障估算结果的准确度。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的各实施例进行详细的阐述。然而，本领域的普通技术人员可以理解，在本申请各实施例中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施例的种种变化和修改，也可以实现本申请所要求保护的技术方案。以下各个实施例的划分是为了描述方便，不应对本申请的具体实现方式构成任何限定，各个实施例在不矛盾的前提下可以相互结合相互引用。
本申请的一个实施例涉及一种确定网络切片可用资源的方法，应用于服务器，本实施例的具体流程图如图2所示，具体包括：
步骤201，获取终端的预置MCS；其中，预置MCS是指终端在参考误块率下可获取的MCS。
步骤202，根据预设的不同误块率下的MCS映射关系，获取网络切片业务的目标误块率下与预置MCS对应的MCS，作为目标MCS。
步骤203，根据目标MCS和预获取的网络切片业务所需的传输块大小，确定终端接入网络切片业务需要消耗的PRB数量。
本实施例中，通过获取终端的预置MCS，其中，预置MCS是终端在参考误块率下可获取的MCS，即在普通移动终端的误块率下可获取的MCS，并根据预设的不同误块率下的MCS映射关系，获取网络切片业务的目标误块率下与预置MCS对应的MCS，将其作为目标MCS，即获取切片终端的误块率下可获取的MCS，然后根据获取到的目标MCS与预获取的网络切片业务所需的传输块大小，能够确定终端接入网络切片业务需要消耗的PRB数量，即可以得到终端级的PRB资源估算结果，满足了ToB切片业务的实际需求。由于传统的通过网规仿真的方式得到某个栅格的MCS时，需要对发射端到接收端的每个环节上都进行准确的评估，才能保证最终预测结果的准确度，涉及到的环节包括：站点工程参数、电子地图、传播模型，以及基于大规模天线(Massive MIMO)业务信道赋形的精准建模，前提条件过多，而本申请实施例只依据预置MCS与预设的不同误块率下的MCS映射关系，来获取切片终端的MCS，无需仿真计算，因此，本申请依赖的前提条件大幅减少，评估因素的随机性降低，极大提高了资源估算的准确性。
下面对本实施例的确定网络切片可用资源的方法的实现细节进行具体的说明，以下内容仅为方便理解提供的实现细节，并非实施本方案的必须。
本实施例的确定网络切片可用资源的方法应用于ToB网络切片业务中，根据ToB行业中应用的业务模型(业务带宽和可靠性)、典型的系统参数配置(载波带宽、双工制式、帧结构等)、终端所处的无线环境ToC网络的网管、 以及测量报告(Measurement Report，MR)的MCS统计数据，可以得到ToB网络切片业务中终端的可获得MCS，然后结合3GPP协议标准中对于传输块大小(Transport Block Size，TBS)的计算原则，即可进行单业务或者多业务综合的PRB资源估算。
在步骤201中，服务器获取现网ToC的栅格的预置MCS，也就是终端的MCS，其中，预置MCS为终端在参考误块率(Block Error Rate，BLER)下可获取的MCS。其中，预置MCS可以从终端的MR中获取。
在具体计算机实现中，以MCS索引值唯一表征该MCS。
可以理解的是，不同的网络终端对业务可靠性的要求不同，其中，可靠性与误块率的关系为：误块率＝1-可靠性，如表1所示：
表1
可靠性 误块率
90％ 10％
99.9％ 0.1％
99.999％ 0.001％
而在不同的误块率下，终端可获取的MCS不同，其中，ToC网络中终端对业务可靠性的要求为90％，即MCS索引值为在参考误块率等于10％下终端可获取的MCS。
在该实施例的方法执行时，预置MCS的索引值可以人工输入或者通过大数据自动获得，若为人工输入，则需要在交互界面输入该MCS索引值，若为大数据自动获得，则可以获得现网中的每一个终端的MCS索引值。
在步骤202中，ToB网络中的不同网络切片业务的可靠性要求不同，在终端接入网络切片业务后，为了便于说明，下面将接入网络切片业务的终端称作“切片终端”，由于不同切片终端的误块率不相同，则需要根据预设的切片终端在不同误块率下的MCS映射关系，获取切片终端在目标误块率下与MCS索引值对应的目标MCS。
其中，参考误块率为普通消费者移动终端的误块率，例如，参考误块率为10％；目标误块率为切片终端的误块率，即终端接入网络切片业务后的误块率，目标误块率可以为0.1％，0.001％。
在一个例子中，MCS映射关系包括：多个参考MCS、备选误块率下每个参考MCS对应的MCS，其中，不同误块率下相对应的各MCS所对应的信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)相匹配。其中，多个参考MCS，即参考MCS索引值，指参考误块率下的多个MCS；在参考误块率下，不同SINR所对应的MCS值不同。
其中，不同误块率包括参考误块率和备选误块率，在一个例子中，参考误块率可以是10％，备选误块率可以是0.1％，0.001％。
在一个例子中，MCS映射关系可以通过以下方式得到：
具体地，首先可以基于链路仿真的方式得到参考MCS，SINR，BLER的仿真结果，然后根据在参考误块率下，不同的备选误块率和参考MCS的对应关 系，以及不同MCS值与SINR的对应关系来建立MCS映射关系表，MCS映射关系可以如表2所示，表中的BLER＝10％为参考误块率，BLER＝0.1％和BLER＝0.001％为备选误块率。
表2
Figure PCTCN2022126008-appb-000001
具体实现中，在上述建立MCS映射关系时，可以先获取参考误块率下，参考MCS索引值对应的SINR，然后在备选误块率下各MCS索引值所对应的各SINR中查找与参考MCS索引值相匹配的SINR，并将该SINR对应的MCS索引值作为与该参考MCS索引值对应的该备选误块率下的MCS索引值，即可得到MCS映射关系。
例如，在参考误块率BLER＝10％时，参考MCS＝10对应的SINR≥0.89，当备选误块率BLER＝0.1％，根据表2可知，SINR＝0.89dB介于参考MCS＝7和参考MCS＝8之间，满足参考MCS＝7，但不满足参考MCS＝8，则在BLER＝0.1％时，终端可获取的目标MCS＝7；同理，当备选误块率BLER＝0.001％时，根据表2可知，SINR＝0.89dB介于参考MCS＝4和参考MCS5＝之间，满足参考MCS＝4，但是不满足参考MCS＝5，则在BLER＝0.001％时，终端可获取的目标MCS＝4。
需要说明的是，上述建立MCS映射关系的方式只是为了便于理解进行的举例说明，具体步骤可不唯一。
在建立好MCS映射关系之后，可以基于表2得到的MCS映射关系，形成BLER＝10％的MCS至BLER＝0.1％和BLER＝0.001％的映射关系表，如表3所示：
表3
Figure PCTCN2022126008-appb-000002
Figure PCTCN2022126008-appb-000003
具体实现中，根据表3中的不同误块率下，参考MCS与目标MCS之间的映射关系，即可得到切片终端在目标误块率下与参考MCS对应的目标MCS。即将现网ToC中终端的基于90％可靠性的MCS索引值映射至基于99.9％、99.999％的高可靠性的目标MCS。
在步骤203中，若终端为普通移动终端，则获取的终端的预置MCS的数量至少为两个，获取的目标MCS与预置MCS的数量相同且一一对应。若终端为固定终端，例如台式电脑，则获取的终端的预置MCS为一个。其中，对于每个目标MCS，都需要根据目标MCS和传输块大小，确定终端基于目标MCS接入网络切片业务需要消耗的PRB数量。
在一个例子中，根据传输块大小(Transport Block Size，TBS)和目标MCS的关系，通过3GPP协议38.214，5.1.3Modulation order,target code rate,redundancy version and transport block size determination(PSDCH)、6.1.4Modulation order,redundancy version and transport block size determination(PUSCH)章节中给定的原则进行计算，可以得到终端基于目标MCS接入网络切片业务需要消耗的PRB数量。
具体实现中，在根据目标MCS和预获取的网络切片业务所需的传输块大小TBS，确定终端接入网络切片业务需要消耗的PRB数量之前，还需根据网络切片业务的业务模型，计算网络切片业务所需的传输块大小。
其中，TBS可以根据下面的公式计算得到：
Figure PCTCN2022126008-appb-000004
其中，业务带宽可以通过下面的公式计算得到：
Figure PCTCN2022126008-appb-000005
其中，业务带宽的单位为bps；
子载波间隔为30k时，调度周期＝0.5*10 -3s，子载波间隔为15k时，调度周期＝1*10 -3s；
若采用频分双工(Frequency Division Duplexing,FDD)方式，上下行的符号比例均取100％，若采用时分双工(Time Division Duplexing，TDD)方式，上下行的符号比例由帧结构决定，典型的2.5ms单周期、2.5ms双周期、5ms单周期的上下行符号比例如表4所示：
表4
周期 上行符号比例 下行符号比例
2.5ms单周期 20.0％ 74.3％
2.5ms双周期 30.0％ 64.3％
5ms单周期 20.0％ 74.3％
在另一个实施例中，在根据目标MCS和预获取的网络切片业务所需的传输块大小，确定终端接入网络切片业务需要消耗的PRB数量之后，还会根据终端接入网络切片业务需要消耗的PRB数量和小区为网络切片业务分配的PRB数量，计算小区支持接入网络切片业务的终端总数量，本实施例的具体实现流程图如图3所示，具体包括：
步骤301，获取终端的预置MCS；其中，预置MCS是指终端在参考误块率下可获取的MCS。
步骤302，根据预设的不同误块率下的MCS映射关系，获取网络切片业务的目标误块率下与预置MCS对应的MCS，作为目标MCS。
步骤303，根据目标MCS和预获取的网络切片业务所需的传输块大小，确定终端接入网络切片业务需要消耗的PRB数量。
其中，步骤301至步骤303与步骤201至步骤203大致相同，此处不再赘述。
步骤304，根据终端接入网络切片业务需要消耗的PRB数量和小区为网络切片业务分配的PRB数量，计算小区支持接入网络切片业务的终端总数量。
在步骤304中，首先根据终端在参考误块率下可获得的各MCS占比，确定终端可获得的各目标MCS占比，并根据终端基于各目标MCS接入网络切片业务需要消耗的PRB数量和各目标MCS占比，可以计算出终端接入网络切片业务平均需要消耗的PRB数量，最后根据平均消耗的PRB数量和小区为网络切片业务分配的PRB数量，即可计算得到小区支持接入网络切片业务的终端总数量。
在一个例子中，可以根据预设的参考MCS与MCS占比的映射关系，将各目标MCS分别对应的各参考MCS所对应的MCS占比，作为各目标MCS占比，其中，参考MCS是指参考误块率下的MCS。
具体地，MCS映射关系、参考MCS与MCS占比的映射关系集成在同一张映射关系表中，如表5所示：
表5
Figure PCTCN2022126008-appb-000006
Figure PCTCN2022126008-appb-000007
根据表5中终端在参考误块率下可获得的各MCS占比，即可映射得到终端基于不同误块率的可获得的各目标MCS占比。
其中，在根据终端在参考误块率下可获得的各MCS占比，确定终端可获得的各目标MCS占比之前，终端可以预先获取在参考误块率下可获得的各MCS占比，具体为：根据终端的测量报告获取终端在参考误块率下可获得的各MCS占比，或者，通过终端的网管获取终端在参考误块率下可获得的各MCS占比。例如，根据网管或MR，得到ToC网络中BLER＝10％时每个小区的终端可获得MCS占比。例如，MCS 0的占比为Y 0％，MCS 1的占比为Y 1％；结合表3，则可映射得到切片终端基于不同目标BLER的可获得MCS占比。
在一个例子中，可以根据终端基于各目标MCS接入网络切片业务需要消耗的PRB数量和各目标MCS占比，采用下面的公式计算终端接入网络切片业务平均需要消耗的PRB数量：
Figure PCTCN2022126008-appb-000008
其中，Z为终端接入网络切片业务平均需要消耗的PRB数量，k为目标MCS，X i％为目标MCS接入网络切片业务需要消耗的PRB数量，Y i％为MCS占比。
根据上述计算得到的平均消耗的PRB数量和小区为网络切片业务分配的PRB数量，采用下面的公式计算出小区支持接入网络切片业务的终端总数：
Figure PCTCN2022126008-appb-000009
其中，W为小区支持接入网络切片业务的终端总数，V为小区为网络切片业务分配的PRB数量，Z为终端接入网络切片业务平均需要消耗的PRB数量。
在本实施例中，在步骤201中的终端为普通移动终端，即获取的终端的预置MCS的数量至少为两个，获取的目标MCS与预置MCS的数量相同且一一对应。
下面以该普通移动终端业务为电网差动保护业务为网络切片业务为例，对该电网差动保护业务的PRB资源进行估算。
需要说明的是，下面的实施方式只是为了便于理解进行的举例说明，其中普通移动终端可不唯一。
假设该电网差动保护业务的网络参数如表6所示：
表6
Figure PCTCN2022126008-appb-000010
确定该电网差动保护业务的可用资源的具体实现流程如下：
首先，获取ToC终端的多个预置MCS，然后根据ToC终端的多个预置MCS获取电网差动保护业务的多个目标MCS，如表7所示：
表7
Figure PCTCN2022126008-appb-000011
在获取电网差动保护业务的多个目标MCS之后，根据预获取的TBS和各目标MCS，计算该业务需要消耗的PRB数量。
具体地，根据表6可以计算得到预获取的TBS：
Figure PCTCN2022126008-appb-000012
在一个例子中，按照3GPP协议38.214，6.1.4Modulation order,redundancy version and transport block size determination(PUSCH)章节中给定的原则得到上行TBS、MCS、PRB的关系表，如表8所示，为了便于理解，表8为部分上行TBS、MCS、PRB的关系：
表8
Figure PCTCN2022126008-appb-000013
Figure PCTCN2022126008-appb-000014
根据TBS、MCS、PRB的关系表，即表8，查找不同MCS条件下对应的PRB数量，如表9所示：
表9
Figure PCTCN2022126008-appb-000015
根据该终端业务，即电网差动保护业务可获得的MCS占比，计算平均单业务消耗的PRB数量：
Figure PCTCN2022126008-appb-000016
根据平均单业务消耗的PRB数量和小区为该终端业务分配的PRB数量，计算小区支持接入该终端业务的终端总数量。
具体地，根据现网的基础配置：总载波带宽为100M，273个PRB，即上行PRB最大分配比例为80％，则小区为该终端业务分配的PRB数量为 273*80％＝218.4，小区支持接入该终端业务的终端总数量为218.4/36＝6。
因此，小区支持接入该终端业务的终端总数量为6个。
在另一个实施例中，若在步骤301中获取的终端的预置MCS只有一个，即终端的位置是固定的，例如，台式电脑，监控摄像头，则在步骤304中计算的终端数量是指在该固定位置所的地理区域内，支持的允许同一时间接入该网络切片业务的终端数量。本实施例的具体实现流程如图4所示，包括：
步骤401，获取终端的预置MCS；其中，预置MCS是指终端在参考误块率下可获取的MCS。
步骤402，根据预设的不同误块率下的MCS映射关系，获取网络切片业务的目标误块率下与预置MCS对应的MCS，作为目标MCS。
步骤403，根据目标MCS和预获取的网络切片业务所需的传输块大小，确定终端接入网络切片业务需要消耗的PRB数量。
其中，步骤401至步骤403与步骤301至步骤303大致相同，此处不再赘述。
步骤404，根据终端接入网络切片业务需要消耗的PRB数量和终端所在区域内被分配的PRB数量，计算该终端所在区域内允许同一时间接入该网络切片业务的终端数量。
为了便于理解，以该固定终端为某1080p视频监控应用为例，对其单摄像头的PRB资源进行估算。
需要说明的是，下面的实施方式只是为了便于理解进行的举例说明，其中固定终端可不唯一。
假设该单摄像头的网络参数如表10所示：
表10
Figure PCTCN2022126008-appb-000017
确定该1080p视频监控应用的可用资源的具体流程如下：
首先，获取该终端的预置MCS，然后根据预置MCS，确定终端的目标 MCS。
由于该终端，即单摄像头业务基于90％可靠性、10％BLER时预置MCS＝25；根据表3，当该终端接入网络切片业务时，可以映射得到该切片终端基于99.9％可靠性、0.1％BLER时，目标MCS＝21。
在获取目标MCS后，根据预获取的TBS和目标MCS，计算该切片终端需要消耗的PRB数量。
具体地，根据表10可以计算得到预获取的TBS：
Figure PCTCN2022126008-appb-000018
在一个例子中，按照3GPP协议TS 38.214，6.1.4Modulation order,redundancy version and transport block size determination章节中给定的原则得到上行TBS、MCS、PRB的关系表，如表11所示，为了便于理解，表11为部分上行TBS、MCS、PRB的关系：
表11
Figure PCTCN2022126008-appb-000019
根据表11可知，目标MCS＝21时，若TBS＝13108bit，则PRB＝8，即该切片终端需要消耗的PRB数量为8。
最终，根据终端接入网络切片业务需要消耗的PRB数量和终端所在区域内被分配的PRB数量，计算该终端所在区域内允许同一时间接入该网络切片业务的终端数量。
根据现网的基础配置：总载波带宽为100M，273个PRB，即上行PRB最大分配比例为80％，则该终端所在区域内被分配的PRB数量为273*80％＝218.4， 则计算该终端所在区域内允许同一时间接入该网络切片业务的终端数量为218.4/8＝27。
因此，该终端所在区域内允许同一时间接入该网络切片业务的终端数量为27个。
本实施例与第二实施例的实现流程大致相同，区别之处在于获取的预置MCS只有一个，因此，最终确定的接入网络片业务的终端数量为该终端所在区域内允许同一时间接入该网络切片业务的终端数量。
