针对现有的技术问题，本申请实施例提供了一种SLA分解方法、设备以及系统。以下分别进行详细说明。
为了便于理解本申请的实施例，首先对SLA指标进行介绍。SLA指标用于表征切片需要满足的要求，即，切片的租户希望切片满足的要求。例如，SLA指标包括以下至少一个：区域分布指标、电池寿命指标、信号覆盖指标、时延指标、传输成功率指标以及容量指标。
对于区域分布指标，区域分布指标用于表征切片的租户希望切片中的小区覆盖的区域的要求。在一具体的实施例中，当区域分布指标只包括指定区域时，区域分布指标的含义为，切片中的小区覆盖指定区域。例如，当区域分布指标只包括A区域时，区域分布指标的含义为，切片中的小区覆盖A区域。在另一具体的实施例中，当区域分布指标包括指定区域以及指定比例时，区域分布指标的含义为，切片中的小区覆盖指定区域的比例大于指定比例。例如，当区域分布指标包括A区域以及98％时，切片中的小区覆盖A区域的比例大于98％，即，A区域中98％的区域都被切片中的小区覆盖。
可以理解的是，区域分布指标还可以令指定区域中的不同区域的指定比例不同，例如，可以令指定区域中的M区域的指定比例为95％，指定区域中的N区域的指定比例为98％等等。即，切片中的小区覆盖M区域的比例大于95％，切片中的小区覆盖N区域的比例大于98％。应理解，区域分布指标的具体实施方式可以是多种多样的，此处只是列举了部分可能的实施方式，不应构成具体的限定。
这里，指定区域是切片的租户希望切片中的小区覆盖的区域。例如，租户在上海开设有a厂区，在北京开设有b厂区，租户希望切片中的小区能够同时覆盖a厂区以及b厂区，所以，指定区域即为a厂区以及b厂区。
对于电池寿命指标，电池寿命指标用于表征切片的租户希望切片中的终端设备的电池寿命需要满足的要求。在一具体的实施例中，当电池寿命指标只包括寿命时间时，电池寿命指标的含义为，切片中的所有终端设备的电池寿命需要大于寿命时间。例如，当电池寿命指标只包括15年时，电池寿命指标的含义为，接入切片的所有终端设备的电池寿命需要大于15年。在另一具体的实施例中，当电池寿命指标包括寿命时间以及指定比例时，电池寿命指标的含义为，切片中电池寿命大于寿命时间的终端设备的比例需要大于指定比例。例如：当电池寿命指标包括15年以及95％时，电池寿命指标的含义为，切片中的终端设备的电池寿命超过15年的比例需要大于95％。
可以理解的是，电池寿命指标还可以令指定区域中不同的区域的终端设备的寿命时间不同，例如，可以令指定区域中的M区域的终端设备的寿命时间为20年，令指定区域中的N区域的终端设备的寿命时间为10年等等，即，令指定区域中的M区域中所有终端设备的电池寿命需要大于20年，令指定区域中的N区域中所有终端设备的电池寿命需要大于15年。此外，电池寿命指标还可以令指定区域中不同的区域的终端设备的指定比例不同，例如，可以令指定区域中的M区域的指定比例为95％，令指定区域中的N区域的指定比例为98％等等。即，M区域中电池寿命大于寿命时间的终端设备的比例需要大于95％，N区域中电池寿命大于寿命时间的终端设备的比例需要大于98％。应理解，电池寿命指标的具体实施方式可以是多种多样的，此处只是列举了部分可能的实施方式，不应构成具体的限定。
在本实施例中，终端设备可以是指设置于位于特殊的地理位置，无法直接通过电网进行供电，只能通过设置在自身体内的电池进行供电的设备。例如，终端设备可以是设置于远离供电电源，无法进行供电的郊外的气象监测设备，可以是设置在不便于电线进行布线， 无法进行供电的区域的智能水表以及智能电表等等仪表设备，也可以是嵌入于人体内的心脏起搏器等等生物健康设备等等。
对于信号覆盖指标，信号覆盖指标用于表征切片的租户希望基站提供给切片中的终端设备的信号强度的要求。在一具体的实施例中，当信号覆盖指标只包括指定信号强度时，信号覆盖指标的含义为，切片中每个终端的信号强度大于指定信号强度。例如，当信号覆盖指标只包括20dBm时，切片中每个终端的信号强度大于20dBm。在另一具体的实施例中，当信号覆盖指标只包括指定信号强度以及指定比例时，信号覆盖指标的含义为，切片中信号强度大于指定信号强度的终端的比例需要大于指定比例。例如，当信号覆盖指标包括20dBm以及98％时，切片中信号强度大于20dBm的终端的比例需要大于98％。
可以理解的是，信号覆盖指标还可以令指定区域中不同区域的指定信号强度不同。例如，可以令指定区域中的M区域的指定信号强度为20dBm，令指定区域中的N区域的指定信号强度为15dBm。即，M区域中每个终端的信号强度大于20dBm，N区域中每个终端的信号强度大于15dBm。信号覆盖指标还可以令不同区域的指定比例不同。例如，可以令M区域的指定比例为95％，N区域的指定比例为98％等等。即，M区域中信号强度大于指定信号强度的终端的比例大于95％，N区域中信号强度大于指定信号强度的终端的比例大于98％。应理解，信号覆盖指标的具体实施方式可以是多种多样的，此处只是列举了部分可能的实施方式，不应构成具体的限定。
这里，指定信号强度是切片的租户希望切片中的终端设备在通信时能够达到的信号强度。例如，租户的终端设备大部分被设置于地下室等信号强度不好的地方，所以，需要确保传输至终端设备的信号强度大于指定信号强度，才能够确保终端设备正常与网络进行通信。
对于时延指标，时延指标用于表征业务数据在切片中传输的时延的要求。在一具体的实施例中，当时延指标只包括时延时间时，时延指标的含义为，终端设备与其他网络设备的业务数据在切片中传输的时延不能大于时延时间。例如，当时延指标只包括10毫秒时，时延指标的含义为，终端设备与其他网络设备的业务数据在切片中传输的时延不能大于10毫秒。这里，其他网络设备可以是服务器、另一个终端设备等等设备，也可以是中继器、基站、服务网关等等网元。
可以理解的是，时延指标还可以令切片中不同的业务的时延时间不同。例如，可以令语音业务的时延时间为5毫秒，令视频业务的时延时间为10毫秒等等。即，终端设备与其他网络设备的语音业务数据在切片中传输的时延不能大于5毫秒，终端设备与其他网络设备的视频业务数据在切片中传输的时延不能大于10毫秒。应理解，时延指标的具体实施方式可以是多种多样的，此处只是列举了部分可能的实施方式，不应构成具体的限定。
对于传输成功率指标，传输成功率指标用于表征业务数据在切片中传输时从源节点成功传输至目的节点的成功率的要求。在一具体的实施例中，当时传输成功率指标只包括通信成功率时，传输成功率指标的含义为，终端设备与其他网络设备之间通过切片成功进行通信(例如，没有出现掉话等问题)的概率大于通信成功率。例如，当传输成功率指标只包括90％时，传输成功率指标的含义为，终端设备与其他网络设备之间通过切片成功进行通信的概率大于90％。其中，通信成功率的含义可以理解为：如果终端设备与服务器进行 10次通信，其中，9次成功进行了通信，则终端设备与服务器之间进行通信的通信成功率为90％。其中，其他网络设备可以是服务器、另一个终端设备等等设备，也可以是中继器、基站、服务网关等等网元。
可以理解的是，传输成功率指标还可以令切片中不同的业务的通信成功率不同。例如，可以令语音业务的通信成功率为95％，视频业务的通信成功率为90％等等。即，终端设备与其他网络设备之间通过切片成功进行语音业务通信的概率大于95％，终端设备与其他网络设备之间通过切片成功进行视频业务通信的概率大于90％。应理解，传输成功率指标的具体实施方式可以是多种多样的，此处只是列举了部分可能的实施方式，不应构成具体的限定。
对于容量指标，容量指标用于表征切片中允许接入的终端设备的数量要求。在一具体的实施例中，当容量指标只包括指定数量时，容量指标的含义为切片允许接入的终端设备的数量大于指定数量。例如，当容量指标只包括1万时，容量指标的含义为切片允许接入的终端设备的数量大于1万。
可以理解的是，容量指标还可以令指定区域中的不同的区域的指定数量不同。例如，指定区域中的M区域的指定数量为2万，指定区域中的N区域的指定数量为3万等等。即，M区域中允许接入的终端设备的数量大于2万，N区域中允许接入的终端设备的数量大于3万。
参见图2，图2是本申请实施例提供的一种SLA分解方法的流程示意图。如图2所示，该方法包括：
101：跨域切片管理设备确定切片的SLA指标。
在本申请实施例中，所述切片包括至少两个分域，每个分域可以设置一个或者多个分域管理设备。在一具体的实施例中，所述至少两个分域包括RAN分域、TN分域以及CN分域。分域管理设备包括RAN管理设备、TN管理设备以及CN管理设备，其中，RAN管理设备用于管理RAN分域，TN管理设备用于管理TN分域，CN管理设备用于管理CN分域。RAN分域可以是接入网，也可以是接入网下的一个或者多个子网，TN分域可以是传输网，也可以是传输网下的一个或者多个子网，CN分域可以是核心网，也可以是核心网下的一个或者多个子网。以下为了陈述方便，均以至少两个分域包括RAN分域、TN分域以及CN分域为例进行说明。
可以理解的是，上述切片划分分域的方式只是作为一种举例，不应构成限定。
在本发明实施例中，跨域切片管理设备确定切片的SLA指标可以为：跨域切片管理设备接收业务管理设备发送的切片的SLA指标。可以理解的是，切片的SLA指标可以是业务管理设备发送给跨域切片管理设备的，也可以是其他的网元发送给跨域切片管理设备的，本发明不作具体限定。

表1候选指标分解结果表格
Figure PCTCN2018076080-appb-000001
以序号为4的候选指标分解结果为例，该候选指标分解结果的含义为：需要将时延指标分解到RAN分域、TN分域以及CN分域，其中，时延指标分解到RAN分域的时延指标为4毫秒，分解到TN分域的时延指标为3毫秒，分解到CN分域的时延指标为2毫秒。应理解，表1只是作为一种示例，不应构成限定。
在本申请实施例中，候选指标分解结果可以是预先设置在跨域切片管理设备内的。例如，可以预先在跨域切片管理设备设置如表1所示的表格，也可以是根据至少两个分域管理设备向跨域切片管理设备发送的分域的预设能力生成。
在本申请实施例中，预设能力可以是分域管理设备的一种或多种网络性能的期望值。其中，网络性能可以是区域分布、电池寿命、时延指标、传输成功率或者容量等等中的至少一种。预设能力与SLA指标是对应的，当SLA指标包括区域分布指标时，预设能力包括区域分布能力；当SLA指标包括电池寿命指标时，预设能力包括电池寿命能力；当SLA指标包括信号覆盖指标时，预设能力包括信号覆盖能力；当SLA指标包括时延指标时，预设能力包括时延能力；当SLA指标包括传输成功率指标时，预设能力包括传输成功率能力；当SLA指标包括容量指标时，预设能力包括容量能力。
在一具体的实施例中，预设能力可以包括多个预设的能力等级。例如，RAN分域的时延能力包括5毫秒、4毫秒以及3毫秒三个能力等级。即，通过调节RAN分域的参数，可以使得终端设备与其他网络设备的业务数据在RAN分域中传输的时延为5毫秒或者4毫秒或者3毫秒。应理解，上述例子只是作为一种示例，不应构成限定。
下面结合具体的实施例说明，跨域切片管理设备如何根据至少两个分域管理设备向跨域切片管理设备发送的分域的预设能力生成候选指标分解结果。例如，RAN分域向跨域切片管理设备上报的预设能力为5毫秒以及4毫秒，TN分域向跨域切片管理设备上报的预设能力为4毫秒以及3毫秒，CN分域向跨域切片管理设备上报的预设能力为3毫秒以及2毫秒，则排列组合后可以生成如表2所示的8个候选分解结果。

(2)跨域切片管理设备计算得到综合结果。其中，综合结果为将至少两个分域中的每个分域的初步分解结果使用跨域计算公式计算得到的结果。
(3)当综合结果满足SLA指标时，跨域切片管理设备将初步指标分解结果映射为SLA分指标。其中，SLA分指标与初步分解结果相同。分域管理设备接收到SLA分指标之后，还需要将SLA分指标映射为自己的分域配置信息，以对分域管理设备进行配置。
下面详细说明对于不同的SLA指标，跨域切片管理设备是如何确定综合结果能够满足SLA条件的。
在步骤102之前，跨域切片管理设备可以接收域指示信息，其中，域指示信息用于指示至少两个分域中的一个或多个分域的类型，此外，域指示信息还可以用于携带跨域计算公式。域指示信息可以是业务管理设备发送给跨域切片管理设备的，也可以是切片设计管理设备发送给跨域切片管理设备的。应理解，域指示信息还可以是其他设备发送给跨域切片管理设备的，此处举例不应该构成具体限定。
在本申请实施例中，如果SLA指标包括电池寿命指标，则至少两个分域包括CN分域以及RAN分域，即，电池寿命指标的实现只与CN分域以及RAN分域相关，与TN分域无关，则初步指标分解结果包括：CN分域的电池寿命指标以及RAN分域的电池寿命指标。这里，域指示信息还携带电池寿命指标对应的跨域计算公式例如，取最小值公式。通过取最小值公式计算分解得到的CN分域的电池寿命指标以及RAN分域的电池寿命指标是否满足电池寿命指标。例如，电池寿命指标为接入切片的所有终端设备的电池寿命需要大于15年时，电池寿命指标分解得到的RAN分域的电池寿命指标为接入切片的所有终端设备的电池寿命需要大于20年，CN分域的电池寿命指标为接入切片的所有终端设备的电池寿命需要大于17年。通过取最小值公式min(a，b)计算综合结果。其中，a为RAN分域的电池寿命指标，b为CN分域的电池寿命指标。根据取最小值公式计算得到的综合结果为17年，比电池寿命指标大，所以，能够满足电池寿命指标。应理解，上述例子只是作为一种举例，不应构成限定。
在本申请实施例中，如果SLA指标包括区域分布指标，则至少两个分域包括RAN分域，即，区域分布指标的实现只与RAN分域相关，与CN分域以及TN分域无关，则初步指标分解结果包括：RAN分域的区域分布指标。例如，区域分布指标为切片中的小区覆盖A区域时，区域分布指标分解的RAN分域的区域分布指标为切片中的小区覆盖A区域。应理解，上述例子只是作为一种举例，不应构成限定。在本实施例中，域指示信息不需要携带区域分布指标对应的跨域计算公式。
在本申请实施例中，如果SLA指标包括信号覆盖指标，则至少两个分域包括RAN分域，即，区域分布指标的实现只与RAN分域相关，与CN分域以及TN分域无关，则初步指标分解结果包括：RAN分域的信号覆盖指标。例如，信号覆盖指标为切片中每个终端的信号强度大于20dBm时，信号覆盖指标分解得到的RAN分域的信号覆盖指标为切片中每个终端的 信号强度大于20dBm。应理解，上述例子只是作为一种举例，不应构成限定。在本实施例中，域指示信息不需要携带信号覆盖指标对应的跨域计算公式。
在本申请实施例中，如果SLA指标包括时延指标，则至少两个分域包括CN分域、TN分域以及RAN分域，则初步指标分解结果包括：CN分域的时延指标、TN分域的时延指标以及RAN分域的时延指标。这里，域指示信息还携带时延指标对应的跨域计算公式，例如，求和公式。通过求和公式计算分解得到的CN分域的时延指标、TN分域的时延指标以及RAN分域的时延指标是否满足时延指标。例如，时延指标为终端设备与其他网络设备的业务数据在切片中传输的时延不能大于10毫秒时，时延指标分解得到的RAN分域的时延指标为终端设备与其他网络设备的业务数据在RAN分域中传输的时延不能大于4毫秒，TN分域的时延指标为终端设备与其他网络设备的业务数据在TN分域中传输的时延不能大于3毫秒，CN分域的时延指标为终端设备与其他网络设备的业务数据在CN分域中传输的时延不能大于2毫秒。通过求和公式SUM(a，b，c)公式计算综合结果。其中，a为RAN分域的时延指标，b为TN分域的时延指标，c为CN分域的时延指标。根据求和公式计算得到的综合结果为9毫秒，比时延指标小，所以，能够满足时延指标。应理解，上述例子只是作为一种举例，不应构成限定。
在本申请实施例中，如果SLA指标包括传输成功率指标，则至少两个分域包括CN分域、TN分域以及RAN分域，则初步指标分解结果包括：CN分域的传输成功率指标、TN分域的传输成功率指标以及RAN分域的传输成功率指标。这里，域指示信息还携带传输成功率指标对应的跨域计算公式，即，乘积公式。通过乘积公式计算分解得到的CN分域的传输成功率指标、TN分域的传输成功率指标以及RAN分域的传输成功率指标是否满足传输成功率指标。例如，传输成功率指标为终端设备与其他网络设备之间通过切片时成功进行通信的概率大于90％时，则分解到RAN分域的传输成功率指标为终端设备与其他网络设备之间通过RAN分域时成功进行通信的概率大于95％，分解到TN分域的传输成功率指标为通过TN分域时成功进行通信的概率大于98％，分解到CN分域的传输成功率指标为通过CN分域时成功进行通信的概率大于98％。通过乘积公式a*b*c计算综合结果。其中，a为RAN分域的传输成功率指标，b为TN分域的传输成功率指标，c为CN分域的传输成功率指标。根据乘积公式a*b*c计算得到的综合结果为91.23％年，比传输成功率指标大，所以，能够满足传输成功率指标。应理解，上述例子只是作为一种举例，不应构成限定。
在本申请实施例中，如果SLA指标包括容量指标，则至少两个分域包括RAN分域、CN分域以及TN分域，则初步指标分解结果包括：RAN分域的容量指标、CN分域的容量指标以及TN分域的容量指标。这里，域指示信息还携带容量指标对应的跨域计算公式，即，取最小值公式。通过取最小值公式计算分解得到的CN分域的容量指标、TN分域的容量指标以及RAN分域的容量指标是否满足容量指标。例如，容量指标为切片接入允许接入的终端设备的数量大于1万时，容量指标分解到RAN分域的容量指标为RAN分域允许接入的终端设备的数量大于2万、TN分域的容量指标为TN分域允许接入的终端设备的数量大于1.5万，CN分域的容量指标为CN分域允许接入的终端设备的数量大于1.2万。通过取最小值公式min(a，b，c)计算得到综合结果。其中，a为RAN分域的容量指标，b为TN分域的容量指标，c为CN分域的容量指标。根据取最小值公式计算得到的综合结果为1.2万，比容量 指标大，所以，能够满足容量指标。应理解，上述例子只是作为一种举例，不应构成限定。
下面详细说明对于不同的SLA指标，跨域切片管理设备是如何确定分域的初步分解结果在分域的实际能力范围内的。
分域的实际能力是分域实际上可以达到的能力。例如，RAN分域的预设能力为时延5毫秒，但是，在实际使用中，由于种种环境因素的影响，RAN分域的实际时延只能达到6毫秒。这时，分域的实际能力为时延6毫秒。可以理解，分域的实际能力与SLA指标是对应的，当SLA指标包括区域分布指标时，实际能力包括实际区域分布能力；当SLA指标包括电池寿命指标时，实际能力包括实际电池寿命能力；当SLA指标包括信号覆盖指标时，实际能力包括实际信号覆盖能力；当SLA指标包括时延指标时，实际能力包括实际时延能力；当SLA指标包括传输成功率指标时，实际能力包括实际传输成功率能力；当SLA指标包括容量指标时，实际能力包括实际容量能力。
当所述SLA指标包括所述电池寿命指标时，所述跨域切片管理设备根据电池寿命参数计算所述至少两个分域中的每个分域的实际电池寿命能力，其中，所述电池寿命参数包括以下至少一种：终端设备接收或发送数据的流程，终端设备接收或发送每条消息所需时间，仿真数据或实时网络中的参考信号接收功率(Reference Signal Receiving Power，RSRP)或参考信号接收质量(Reference Signal Receiving Quality，RSRQ)分布图、不同参考信号接收功率/参考信号接收质量对应的数据包大小及重传次数，终端设备每次发送或接收数据或不发送不接收数据分别对应单位时间所需的耗电，延长的非连续接收相关参数，非连续接收相关参数，节电模式相关参数，终端设备中传感器的耗电以及终端设备电池的自损耗情况。其中，终端设备接收或发送数据的流程就是终端设备在通信过程中和基站需要交互的信息流程。比如，对于如图3所示的终端设备主动发送数据时所涉及的流程。终端设备接收或发送每条消息所需时间可以是对于图3所示的流程中，每条消息所需的发送及接收时间。延长的非连续接收相关参数可以是中eDRX(extended DRX)的循环周期、对应的寻呼发送窗时间长度及在eDRX中监听消息的耗电情况等等中的至少一个。非连续接收相关参数可以是终端设备在idle态时DRX的循环周期及在DRX中监听消息的耗电情况等等中的至少一种。节电模式相关参数可以是PSM模式(power saving mode)中的激活时间参数及在激活时间内中监听消息的耗电情况等等中的至少一个。终端设备电池的自损耗的含义为电池每年都会按照一定的比例放电导致电池寿命缩短等等。
当所述SLA指标包括所述区域分布指标时，所述跨域切片管理设备根据区域分布参数计算所述至少两个分域中的每个分域的实际区域分布能力，其中，所述区域分布参数至少包括基站分布地图。
当所述SLA指标包括所述信号覆盖指标时，所述跨域切片管理设备根据信号覆盖分布参数计算所述至少两个分域中的每个分域的实际信号覆盖能力，其中，所述信号覆盖分布参数至少包括：仿真数据或实时网络中的参考信号接收功率或参考信号接收质量分布图。
当所述SLA指标包括所述时延指标时，所述跨域切片管理设备根据时延参数计算所述至少两个分域中的每个分域的实际时延能力，其中，所述时延参数包括以下至少一种：当前的资源利用率，仿真数据或实时网络中的参考信号接收功率或参考信号接收质量分布图。 所述当前的资源利用率可以是小区中PRB(physical resource block)的利用率、控制信道元素(Control Channel Element，CCE)的利用率、小区中可剩余接入的用户数等等中的至少一种。
当所述SLA指标包括所述传输成功率指标时，所述跨域切片管理设备根据传输成功率参数计算所述至少两个分域的每个分域的实际传输成功率能力，其中，所述传输成功率参数包括以下至少一种：小区中实时网络的业务成功率、仿真数据或实时网络中的参考信号接收功率、参考信号接收质量分布图以及各域的业务成功率。小区中实时网络的业务成功率可以是小区中的无线资源链接(radio resource connection，RRC)建立成功率、业务无线承载(radio bearer，RB)建立成功率、切换成功率等等中的至少一种。
当所述SLA指标包括所述容量指标时，所述跨域切片管理设备根据容量参数计算所述至少两个分域中的每个分域的实际容量能力，其中，所述容量参数包括以下至少一种：小区剩余资源块资源率，仿真数据或实时网络中的参考信号接收功率或参考信号接收质量分布图以及剩余的业务容量。小区剩余资源块资源率可以是小区中PRB(physical resource block)的利用率等等中的至少一种。剩余的业务容量可以是TN、CN剩余的处理能力以及剩余的可处理数据包大小等等中的至少一种。
在本申请实施例中，满足SLA指标的候选指标分解结果的数量可以是一个或者多个。如果满足SLA指标的候选指标分解结果的数量为多个，则可以根据候选指标分解结果的优先级别从满足SLA指标的候选指标分解结果中选出一个目标指标分解结果。例如，以表2为例，当SLA指标为终端设备与其他网络设备的业务数据在切片中传输的时延不能大于10毫秒时，序号为6、7以及8的候选指标分解结果均能够满足SLA指标。如果序号为6的优先级别最高、序号为7的优先级别次之，序号为8的优先级别最低，则可选选择序号为6的候选指标分解结果以作为目标指标分解结果。
在本申请实施例中，候选指标分解结果的优先级别可以根据优先级别策略进行确定，而优先级别策略可以根据候选指标分解结果的成本、占用资源以及调度时间等因素进行确定。其中，候选指标分解结果的成本、占用资源以及调度时间可以是分域管理设备向跨域切片管理设备上报分域分解结果的成本计算得到的。例如，以序号为1的候选指标分解结果为例，RAN分域要实现5毫秒的时延的调度时间为3毫秒，TN分域要实现4毫秒的时延的调度时间为2毫秒，CN分域要实现3毫秒的调度时间的成本为1毫秒，则RAN分域管理设备向跨域切片管理设备发送RAN分域要实现5毫秒的调度时间，TN分域管理设备向跨域切片管理设备发送TN分域要实现4毫秒的时延的调度时间,CN分域管理设备向跨域切片管理设备发送CN分域要实现3毫秒的时延的调度时间。跨域切片管理设备根据RAN分域、TN分域以及CN分域的调度时间计算得到候选指标分解结果的调度时间为3毫秒+2毫秒+1毫秒＝6毫秒。可以理解，优先级别策略遵循以下至少一个原则：
(1)成本越高的候选指标分解结果的优先级别越低，成本越低的候选指标分解结果的优先级别越高；
(2)占用资源越多的候选指标分解结果的优先级别越低，占用资源越少的候选指标分解结果的优先级别越高；
(3)调度时间越长的候选指标分解结果的优先级别越低，调度时间越短的候选指标分解结果的优先级别越高。
在本申请实施例中，优先级别策略是预先存储在跨域切片管理设备中的；或者，优先级别策略是业务管理设备下发至跨域切片管理设备的；或者，优先级别策略是切片设计管理设备下发至跨域切片管理设备的，可以理解，优先级别策略还可以存储在其他的设备中，此处就不再一一举例。
在本技术方案中，跨域切片管理设备将SLA指标分解为至少两个分域的分域分解结果，并发送给分域管理设备，以使得分域管理设备可以根据分域分解结果为切片分配资源，从而建立切片。由于SLA指标具有多维度参数指标，每个维度的参数指标都能表征租户在其中一个方面的要求，所以，SLA指标能够准确地描述租户的要求，例如，租户进行通信业务时对切片的性能要求。故此，将SLA指标运用到建立切片的过程中，能够使得切片的配置是根据SLA指标来建立的，进而使得建立的切片更准确地符合租户的要求。其中，切片的配置可以是区域配置、参数配置等各类配置信息。

在本申请实施例中，域指示信息可以是业务管理设备发送给跨域切片管理设备的，也可以是切片设计管理设备发送给跨域切片管理设备的。应理解，域指示信息还可以是其他设备发送给跨域切片管理设备的，此处举例不应该构成具体限定。
