背景技术
大数据时代，终端侧会产生海量数据，通常这类数据有时候需上传给云服务器。虽然这类数据对时效性没要求，但对资费很敏感，通常将这类数据在传输过程中产生的流量称之为背景流量(Background Data)。如图1所示，针对车企，可以使用运营商网络上传地图信息给云服务器，用于制定高清地图。
目前现有技术中，策略控制功能(Policy Control Function，PCF)网元可以根据从应用功能(Application Function，AF)网元处接收到的需求信息，制定业务数据传输策略。如果PCF网元处不具有AF所请求的业务数据传输策略，则PCF网元从统一数据库(Unified data repository，UDR)网元处获取该AF网元对应的所有业务数据传输策略以及每套业务数据传输策略对应的网络区域信息。这样PCF网元便可以基于来自UDR的所有业务数据传输策略、需求信息以及运营商策略，选择至少一套业务数据传输策略，用于传输业务数据。
但是，现有技术中，PCF网元没有足够多的信息确定精准的业务数据传输策略。
发明内容
本申请实施例提供一种传输策略确定方法、策略控制方法及装置，用以解决现有技术中存在的PCF网元没有足够多的信息确定精准的业务数据传输策略的问题。
为了解决上述技术问题，本申请实施例提供如下技术方案：
第一方面，本申请实施例提供一种传输策略确定方法，包括：策略控制网元接收来自切片管理控制网元的第一网络区域中网络的第一信息，该第一信息包括：第一时间段内网络的负载信息和第一时间段内至少一个网络切片的负载信息。或者第一信息包括第一时间段内网络的负载信息。或者第一信息包括第一时间段内至少一个网络切片的负载信息。其中，网络包括至少一个网络切片。策略控制网元根据第一信息，确定位于第一网络区域内的终端的业务数据传输策略。
示例性的，网络的负载信息可以为网络的负载等级或者网络的拥塞等级或者网络的性能。网络切片的负载信息可以为以下中的至少一个：网络切片的负载等级、网络切片的拥塞等级、网络切片的质量和质量要求之间的关系、网络切片的性能。
应理解，网络的负载信息还可以是用于指示网络的负载等级或者网络的拥塞等级或者网络的性能的指示信息。
应理解，网络切片的负载信息还可以是用于指示以下信息中至少一个的指示信息：网络切片的负载等级、网络切片的拥塞等级、网络切片的质量和质量要求之间的关系、 网络切片的性能。
本申请实施例提供一种传输策略确定方法，策略控制网元通过从切片管理控制网元处获取第一网络区域中网络在第一时间段内的负载信息和/或第一时间段内至少一个网络切片的负载信息，由于第一时间段内网络的负载信息通常反映网络是否处于空闲态，第一时间段内至少一个网络切片的负载信息可用于确定网络的负载信息。因此可以得到第一时间段内网络的状态。如果网络处于空闲态，则意味着此时该网络具有空闲资源，即网络在满足至少一个网络切片的运行质量的同时还存在空闲资源。因此，策略控制网元可以根据第一时间段内网络的状态，确定终端的业务数据传输策略。这样一方面可以避免终端的业务数据传输影响到该网络中其他网络切片的运行质量。另一方面，可以充分的利用网络的空闲资源。
在一种可能的实现方式中，业务数据传输策略包括第二时间段，第二时间段为第一时间段内网络的负载信息满足预设网络负载要求的时间段。在第二时间段内，如果网络处于空闲态时，则终端在第二时间段内传输业务数据，可以利用网络的空闲资源来最大限度传输终端的业务数据，且不影响该网络中至少一个网络切片的运行质量。

策略控制网元20，用于接收来自切片管理控制网元10的第一网络区域中网络的第一信息。以及用于根据第一信息，确定位于第一网络区域内的终端的业务数据传输策略。

可选的，业务数据传输策略包括第二时间段，该第二时间段为第一时间段内网络的负载信息满足预设网络负载要求的时间段。

应理解，至少一个网络切片的质量与网络切片的质量要求之间的关系可以理解为： 至少一个网络切片中每个网络切片的质量与该网络切片的质量要求之间的关系。由于至少一个网络切片加入同一个网络之后，彼此的运行质量相互影响，故通常可以将一个网络切片的质量理解为：网络切片所在的网络满足该网络切片的SLA的程度。
示例性的，本申请实施例中可以将网络切片的质量以百分数表示(例如，网络切片所在的网络满足网络切片的SLA的程度为90％，即underfitting)，将网络切片的质量要求也以百分数表示。因此，可以根据网络切片的质量和质量要求之间的大小，确定网络切片的质量与网络切片的质量要求之间的关系。
示例性的，网络切片的质量与网络切片的质量要求之间的关系包括：网络切片的质量高于网络切片的质量要求所要求的质量。比如Slice SLA fulfilment信息为120％，即当前网络能够120％满足切片的质量要求，也可以理解为网络切片在网络中的运行质量良好。或者，网络切片的质量低于网络切片的质量要求所要求的质量，比如Slice SLA fulfilment信息为80％，即当前网络只能够80％满足切片的质量要求，也可以理解为网络切片在网络中的运行质量不好。或者，网络切片的质量等于网络切片的质量要求所要求的质量。比如Slice SLA fulfilment信息为100％或者99.99％，即当前网络能够100％或者99.99％满足切片的质量要求，网络切片在网络中的运行质量良好。
值的解释的，网络切片的质量等于网络切片的质量要求所要求的质量，并不意味着两者完全相等，只要两者接近或者网络切片的质量在网络切片的质量要求上下浮动程度不大，都可以理解为等于。
应理解，本申请实施例中的第一网络区域可以包括步骤101中的网络或者至少一个网络切片所在的至少一个网络区域。
本申请实施例中的网络区域可以为追踪区域(tacking area，TA)、TA列表、路由区域(routing area，RA)或者RA列表、小区(cell)或者小区列表(Cell list)或者全球定位系统位置(GPS(Global Position System，物理区域)或者GPS列表(GPS list))中的至少一个。其中，TA列表包括至少一个TA。RA列表包括至少一个RA。小区列表包括至少一个小区。本申请实施例中涉及到的网络区域均可以参考此处的描述，在此统一说明，后续不再赘述。
以第一网络区域为TA为例，第一网络区域可以包括TA1、TA2以及TA3。则步骤101中的网络为TA1中的网络1、TA2中的网络2以及TA3中的网络3。
本申请实施例中的第一时间段包括至少一个时间段。第一时间段内网络的负载信息可以指至少一个时间段中每个时间段内网络的负载信息。第一时间段内至少一个网络切片的负载信息可以为至少一个时间段中每个时间段内网络切片的负载信息。
示例性的，第一时间段可以为Timestamp、时间窗。例如，第一时间段包括：2018年11月20日22:00-2018年11月21日08：00、2018年11月21日22:00-2018年11月22日08:00、2018年11月22日22:00-2018年11月23日08：00。
步骤102、切片管理控制网元向策略控制网元发送第一网络区域中网络的第一信息。
示例性的，切片管理控制网元向策略控制网元发送时，还可以发送该第一信息对应的网络的标识，和第一网络区域的标识。
示例性的，步骤102具体可以通过以下方式实现：切片管理控制网元可以向策略 控制网元发送网络切片可用性通知响应服务操作(Nnssf_NSSAIAvalability_Notify response)，以使得策略控制网元可以从网络切片可用性通知响应中得到第一信息。其中，网络切片可用性通知响应中携带第一信息。
步骤103、策略控制网元接收来自切片管理控制网元的第一网络区域中网络的第一信息。
步骤104、策略控制网元根据第一信息，确定位于第一网络区域内的终端的业务数据传输策略。
可选的，策略控制网元通过接收来自切片管理控制网元的第一时间段内网络的负载信息，可以确定第一时间段内网络处于空闲态还是非空闲态。
例如，如果第一时间段内网络的负载等级或者网络的拥塞等级小于或等于第一阈值，预示着第一时间段内网络的负载低于第一阈值或者不拥塞，或者在第一时间段内网络处于空闲态，则策略控制网元可以确定在第一时间段内传输终端的业务数据(例如，背景流量)。如果第一时间段内网络的负载等级或者网络的拥塞等级大于第一阈值，预示着第一时间段内网络的负载过高或者网络拥塞，或者在第一时间段内网络处于非空闲态。
切片管理控制网元向策略控制网元发送第一时间段内至少一个网络切片的负载信息，当第一时间段内至少一个网络切片中任一个网络切片的负载等级或者任一个网络切片的拥塞等级小于或等于第二阈值情况下，预示着第一时间段内该任一个网络切片的负载低于第二阈值或者该任一个网络切片不拥塞。如果第一时间段内至少一个网络切片中任一个网络切片的负载等级或者任一个网络切片的拥塞等级大于第二阈值情况下，预示着第一时间段内任一个网络切片的负载过高或者该任一个网络切片拥塞。
可选的，本申请实施例中的业务数据为背景流量(Background Data，BD)，也可以称为背景数据。
在本申请的实施例中，背景流量是指对传输时效性没要求(或者不敏感)的业务数据在传输过程中所产生的流量。或者该背景流量是指对传输时效性没要求，但对资费要求高(或者敏感)的业务数据在传输过程中所产生的流量。或者用于背景流量传输的网络切片没有SLA要求，即只要网络允许传输背景流量即可，没有传输质量(比如传输时延、传输带宽)要求，因此，可以在网络空闲时传输背景流量。
本申请实施例提供一种传输策略确定方法，策略控制网元通过从切片管理控制网元处获取第一网络区域中网络在第一时间段内的负载信息和/或第一时间段内至少一个网络切片的负载信息，由于第一时间段内网络的负载信息通常反映网络是否处于空闲态。第一时间段内至少一个网络切片的负载信息可用于确定网络的负载信息。因此可以得到第一时间段内网络的状态。如果网络处于空闲态，则意味着此时该网络具有空闲资源，即网络在满足至少一个网络切片的运行质量的同时还存在空闲资源。因此，策略控制网元可以根据第一时间段内网络的状态，确定终端的业务数据传输策略。这样一方面可以避免终端的业务数据传输影响到该网络中至少一个网络切片的运行质量。另一方面，可以充分的利用网络的空闲资源。
在一种可选的实现方式中，本申请实施例中的业务数据传输策略包括第二时间段，该第二时间段为第一时间段内网络的负载信息满足预设网络负载要求的时间段。这样 可以使得终端在网络中的第二时间段内传输业务数据时，不影响该网络中至少一个网络切片的运行质量的同时，还可以充分利用网络的空闲资源。
例如，第二时间段为第一时间段内网络的负载等级小于或等于预设网络负载要求的时间段。或者，第二时间段为第一时间段内网络的拥塞等级小于或等于预设网络拥塞要求的时间段。或者，第二时间段为第一时间段内网络的拥塞等级小于或等于预设网络拥塞要求的时间段和网络的负载等级小于或等于预设网络负载要求的时间段。也即第二时间段为可以网络处于空闲态的时间段。
本申请实施例中对预设网络负载要求、预设网络拥塞要求不做限定。该预设网络负载要求、预设网络拥塞要求可以由策略控制网元从AF网元处获取，或者由网管配置给策略控制网元。
应理解，本申请实施例中第二时间段包括至少一个时间段。该至少一个时间段可以为连续的时间段，也可以为非连续的时间段，本申请实施例对此不作限定。
在一些可选的实现方式中，本申请实施例提供的方法还可以包括：策略控制网元确定第二时间段。
示例性的，策略控制网元确定第二时间段可以通过以下方式a或方式b中的任一个实现：
方式a，策略控制网元根据第一时间段内网络的负载信息和第一时间段内至少一个网络切片的负载信息中的至少一个，确定第二时间段。
例如，第一时间段为T1-T5。如果T1-T3时间段内网络处于空闲态，T4-T5时间段内网络处于非空闲状态，则策略控制网元可以确定第二时间段为T1-T3时间段。
方式b，策略控制网元接收来自切片管理控制网元的用于指示第二时间段的信息。策略控制网元根据用于指示第二时间段的信息，确定第二时间段。
在方式b所示的情况下，由切片管理控制网元确定第二时间段，并将第二时间段的信息发送给策略控制网元。
本申请实施例中，切片管理控制网元确定第二时间段的过程可以参考方式a中由策略控制网元确定第二时间段的过程。具体的，将方式a中的策略控制网元替换为切片管理控制网元即可。此处不再赘述。
示例性的，用于指示第二时间段的信息可以为第二时间段的起始时间和持续时间。或者用于指示第二时间段的信息可以为第二时间段的起始时间和结束时间，即为第二时间段。
在一种可选的实现方式中，当第一信息包括第一时间段内至少一个网络切片的负载信息时，如图7所示，本申请实施例提供的方法在步骤104之前，还包括：
步骤105、策略控制网元根据第一时间段内至少一个网络切片的负载信息，确定第一时间段内网络的负载信息。
示例性的，如果策略控制网元确定第一时间段内至少一个网络切片中任一个网络切片的负载等级或者网络切片的拥塞等级小于或等于第三阈值，预示着第一时间段内网络的负载信息为不拥塞或者处于空闲态。或者，如果策略控制网元确定第一时间段内至少一个网络切片中全部或者部分网络切片的负载等级或者网络切片的拥塞等级小于或等于第三阈值，预示着第一时间段内网络的负载信息为不拥塞或者处于空闲态。
示例性的，如果策略控制网元确定第一时间段内至少一个网络切片中存在一个网络切片的负载等级或者网络的拥塞等级大于第三阈值，预示着第一时间段内网络的负载信息为拥塞或者处于非空闲态。或者，如果策略控制网元确定第一时间段内至少一个网络切片中存在全部或者部分网络切片的负载等级或者网络的拥塞等级大于第三阈值，预示着第一时间段内网络的负载信息为拥塞或者处于非空闲态。
应理解，策略控制网元根据第一时间段内至少一个网络切片的负载信息，确定第一时间段内网络的负载信息的过程属于策略控制网元内部实现，上述方法只是示例。
应理解，策略控制网元还可以根据第一时间段内至少一个网络切片的负载信息以及本地运营商策略(比如，上述网络切片的负载等级或者拥塞等级与第三阈值比较逻辑)，确定第一时间段内网络的负载信息。
具体的，步骤104可以通过以下方式实现：策略控制网元根据第一时间段内网络的负载信息，确定位于第一网络区域内的终端的业务数据传输策略。

一方面，第一网络区域和第二网络区域可以相同，例如，如果第二网络区域包括TA列表，则第一网络区域可以为TA列表包括的至少一个TA。
另一方面，第一网络区域也可以为第二网络区域的子集。例如，第一网络区域可以为TA列表包括的至少一个TA中的部分TA，本申请实施例对此不做限定。
可选的，作为本申请的一个可选的实现方式，本申请实施例提供的方法还包括：策略控制网元根据获取到的业务数据传输需求，确定执行步骤101。
其中，业务数据传输需求用于指示业务提供服务器期待的业务数据传输策略。
示例性的，策略控制网元可以通过以下方式获取业务数据传输需求：例如，策略控制网元接收来自应用功能网元或者切片管理控制网元的业务数据传输需求。又例如，业务数据传输需求可以是运营商配置在策略控制网元上的。
具体的，网管网元将业务数据传输需求发送给切片管理控制网元，或者运营商将业务数据传输需求配置在切片管理控制网元上，然后策略控制网元从切片管理控制网元处获得业务数据传输需求。
可选的，应用功能网元可以由网络切片租户管控。示例性的，策略控制网元可以通过NEF网元接收来自应用功能网元的业务数据传输需求。

方式2、如果业务数据传输需求中携带第一指示信息，则策略控制网元根据第一指示信息，确定位于第二网络区域中的终端的标识，则策略控制网元根据位于第二网络区域中的终端的标识，向数据分析网元查询得到位于第二网络区域中的终端的标识对应的至少一个网络区域。并将得到的至少一个网络区域确定为第二网络区域。
示例性的，本申请实施例中的终端的标识可以为以下一个或者多个：网际协议地址(internet protocol，IP)、签约永久标识(subscription permanent identifier，SUPI)、永久设备标识(permanent equipment identifier，PEI)、通用公共签约标识(generic public subscription identifier，GPSI)、国际移动用户标识符(international mobile subscriber identifier，IMSI)、国际移动设备标识(international mobile equipment identity，IMEI)、IP五元组(5-tuple)和移动台国际综合业务数字网络号码(mobile station international integrated service digital network number，MSISDN)。下述实施例中但凡涉及到终端的标识信息均可以参考此处的描述，后续不再赘述。

示例2，如果业务数据传输需求中未携带用于确定第二网络区域的信息，则策略控制网元可以基于ASP ID向数据分析网元查询得到该ASP ID标识的应用功能网元上注册的终端标识列表，然后基于终端标识列表向数据分析网元查询得到终端标识列表对应的Network Area，并将终端标识列表对应的Network Area确定为第二网络区域。或者策略控制网元直接根据ASP ID向数据分析网元查询得到该ASP ID标识的应用功能网元上注册的终端对应的Network Area。
步骤107、切片管理控制网元接收来自策略控制网元的第一请求。

应理解，本申请实施例中的终端可以指第一网络区域中的至少一个终端。
其中，第三时间段用于指示业务提供服务器期待的至少一个终端中每个终端的业务数据传输时间。第一用户数用于指示业务提供服务器期待的传输业务数据的终端数目。

在一些可选的实施例中，如图8所示，本申请实施例提供的方法还可以包括：
步骤108、切片管理控制网元从数据分析网元处获取第三信息。

例如，第三信息中的时间信息为从2018年3月1日到2018年3月8日。这样切片管理控制网元便可以确定该网络切片的第三信息为2018年3月1日到2018年3月8日收集到的。
应理解，在一些可选的实现方式中，切片管理控制网元接收到来自策略控制网元的第一请求，便可以执行步骤108。
具体的，当一个网络切片的第三信息包括：时间信息、区域信息、该网络切片中第一最大用户数、网络切片的业务信息时，该网络切片的第三信息用于切片管理控制网元确定指定时间段内该指定区域内该网络切片上至少一个业务的业务信息以及第一最大注册用户数。具体的，当一个网络切片的第三信息包括：时间信息、区域信息、网络切片的至少一个业务的信息时，该网络切片的第三信息用于切片管理控制网元确定指定时间段内指定区域内该网络切片上至少一个业务的业务信息。
可选的，在步骤108之前，本申请实施例提供的方法还包括：切片管理控制网元向数据分析网元发送第二请求，以使得数据分析网元接收来自切片管理控制网元的第二请求。
示例性的，第二请求可以为：数据分析信息请求(Nnwdaf_AnalyticsInfo_Request)。
其中，该第二请求用于请求第三信息，第二请求包括第二网络区域的标识以及至少一个网络切片的以下信息中的至少一个：标识信息、时间信息。
应理解，切片管理控制网元可以通过与数据分析网元之间的接口向数据分析网元发送第二请求。
也即切片管理控制网元通过向数据分析网元发送第二请求，以从数据分析网元处订阅时间信息指示的时间段内第二网络区域中的至少一个网络切片的第三信息(也可以称为统计信息，即estimated per slice statistics)。
本申请实施例对数据分析网元获取至少一个网络切片中每个网络切片对应的第三信息的过程不作限定，具体可以参考现有技术中的描述。
可选的，切片管理控制网元接收到第三信息以后，还可以向数据分析网元发送用于指示接收到第三信息的响应。

步骤109、切片管理控制网元获取第四信息，该第四信息包括至少一个网络切片对应的以下信息中的至少一个：第三用户数、终端标识列表。
应理解，切片管理控制网元可以根据第四信息确定至少一个网络切片中存在的用户数，即至少一个网络切片中驻留的用户数。用以帮助切片管理控制网元确定网络切片中还可以容纳或者允许接入的用户数。或者便于切片管理控制网元确定该网络切片中是否还可以容纳或者允许用户接入。
作为一种可能的实现方式，步骤109具体可以通过以下方式实现：切片管理控制网元向数据分析网元或者服务于第一网络区域的至少一个接入和移动性管理功能网元发送第三请求，以使得数据分析网元或者服务于第一网络区域的至少一个接入和移动性管理功能网元接收来自切片管理控制网元的第三请求。切片管理控制网元接收来自数据分析网元或者至少一个接入和移动性管理功能网元的第四信息。
其中，第三请求用于请求第四信息，第三请求包括至少一个网络切片的以下信息中的至少一个：标识信息、时间信息、区域信息；
可选的，切片管理控制网元接收到第四信息以后，还可以向数据分析网元或者至少一个接入和移动性管理功能网元发送用于指示接收到第四信息的响应。
由于一个切片管理控制网元可以管理多个接入和移动性管理功能网元，一个接入和移动性管理功能网元通常包括多个TA，一个区域信息指示的网络区域内可以支持多个接入和移动性管理功能网元。因此，切片管理控制网元可以通过TA/S-NSSAI寻址在该TA下支持S-NSSAI的至少一个接入和移动性管理功能网元。
上述图8和图9分别介绍了切片管理控制网元如何获取第三信息和第四信息的方式，作为一种可选的方式，本申请实施例中的步骤101具体可以通过以下方式实现：切片管理控制网元根据以下信息中的至少一个确定第一信息：第二信息、第三信息、第四信息。
在一种可选的实现方式中，本申请实施例提供的方法在步骤101之前还包括：切片管理控制网元获取需求信息，该需求信息用于指示至少一个网络切片的质量要求。
示例性的，需求信息可以包括：至少一个网络切片中每个网络切片的标识信息、第二最大注册用户数和至少一个业务的业务要求信息中的至少一项。
示例性的，业务要求信息用于指示租户要求网络能够业务的要求。
其中，第二最大注册用户数表示一个网络切片被要求注册的最大注册用户数。例如，10million。
可选的，该需求信息还可以包括：区域信息和时间信息中的至少一项。此外，该需求信息还可以包括带宽要求、时延要求等。
示例性的，应用功能网元通过策略控制网元将需求信息发送给切片管理控制网元，也即切片管理控制网元通过策略控制网元从租户管控的应用功能网元处获取需求信息。或者需求信息也可以是运营商配置在切片管理控制网元上的。或者需求信息可以是网管网元发送给该切片管理控制网元。可选的，应用功能网元可以由切片租户管控。
示例性的，业务要求信息包括：Application ID、第二最大用户数(Required Maximum Users for the Application，即租户要求网络能够满足的该业务的最大用户数)、第二平均业务体验(Required Average Service MOS，即租户要求网络能够满足的该业务的平均业务体验)、第二业务体验区间信息(Requested Service MOS range，即租户要求网络能够满足的该业务的业务体验区间)、以及第二业务满意度(How many percentage UE’s experience should be satisfied，即租户要求网络能够满足的该业务的用户满意度)中的至少一个。
其中，第二最大用户数表示一个业务中的最大用户数，也即使用某个业务的总业务数。例如，10000。业务标识用于识别该切片中的业务。第二业务体验区间信息用于表示该业务中的业务体验要求。
示例性的，网络切片中的业务可以为语音业务为例，第二MOS的范围为[0.0，5.0]，例如，第二MOS大于或等于3.0，小于或等于5.0时，才能满足语音业务体验要求，即MOS＝3.0为满足语音业务体验的最低要求。在满足MOS分大于或等于3.0的情况下，按照好的程度递增，MOS可以是4.0、4.5、5.0等等。其中，MOS值越高，对应语音业务的QoS参数要求越严苛，对于网络质量要求越高，归根结底对于网络资源要求越高，也可以理解为网络切片的资源要求越高。
第二业务满意度用于表示对于业务租户要求该业务中满足第二业务体验区间信息的业务数占总业务数的比例。例如，该比例为一个第一阈值，即租户要求该业务中满足第二业务体验区间信息的业务数占总业务数的比例大于或等于第一阈值。本申请实施例对第一阈值不作限定。
例如，租户通常情况下会向运营商提出业务满意度要求，比如针对语音业务，要求MOS大于或等于3.0的业务数占总业务数的比例大于等于95％。
具体的，切片管理控制网元根据第二信息、第三信息以及第四信息中的至少一个，确定第一信息，可以通过以下方式实现：
示例性的，假设一个网络切片只有一个业务，租户要求业务体验(即Service MOS)高于4.0，并且要求95％以上的用户业务满意度，该网络切片的质量和质量要求有如下 两种情况：
第一种情况，切片管理控制网元确定网络能够120％满足网络切片的质量要求，即该网络切片的第三信息中业务MOS为4.8，并且有98％的用户业务满意度。这种情况，网络切片对应的质量高于网络切片的质量要求所要求的质量，可以称之为过拟合(Overfitting)。
第二种情况，切片管理控制网元根据确定网络能够80％满足网络切片的质量要求，即该网络切片的第三信息中业务MOS为3.2，并且有76％的用户业务满意度。这种情况，网络切片对应的质量低于网络切片的质量要求所要求的质量，可以称之为欠拟合(underfitting)。
示例性的，切片管理控制网元从第三信息中获取一个网络切片在一个网络区域中对应一个时间段内租户或者业务提供方要求的该网络切片的用户数，从第四信息中获取该网络切片中在该网络区域对应该时间段内驻留的用户数。如果租户或者业务提供方要求的该网络切片的用户数大于该时间段内驻留在该网络切片中的用户数，则切片管理控制网元可以认为网络切片对应的质量网络切片对应的质量高于网络切片的质量要求所要求的质量，可以称之为过拟合，意味着该网络切片中还可以允许更多用户，即网络切片的负载信息为不拥塞或者空闲。反之，可以确定网络切片对应的质量网络切片对应的质量低于网络切片的质量要求所要求的质量。
值得说明的是，上述实施例只是确定网络切片的质量和网络切片的质量要求之间的关系中的方法中的一种，具体更复杂的场景，比如多个网络切片中存在多个业务情况下，需要设计更复杂的算法，属于数据分析网元内部产品实现。然后，实际操作过程中，引入一个新的网络切片或者未签署SLA的网络切片，可能会对现有网络切片的运行质量产生影响，因此在决定一个网络切片的质量和网络切片的质量要求之间的关系时，同样处理该网络切片本身的第三信息之外，可选的，还要参考其他网络切片的第三信息。
具体的，步骤101可以通过以下方式具体实现：切片管理控制网元根据至少一个网络切片中每个网络切片各自对应的第三信息以及预配置策略，确定每个网络切片各自对应的网络切片的质量和网络切片的质量要求之间的关系。
示例的，预配置策略可以是针对网络切片中最大注册用户数的要求。在决定该网络切片的网络切片的质量和网络切片的质量要求之间的关系时，考虑当前网络中能够满足该网络切片的第一最大注册用户数与该网络切片中第二最大注册用户数的要求之间的大小关系。大小关系可以是，高于、低于、等于或者接近等等。
例如，切片管理控制网元根据NS1对应的第三信息以及预配置策略，确定NS1对应的网络切片的质量和网络切片的质量要求之间的关系。切片管理控制网元根据NS2对应的第三信息以及预配置策略，确定NS2对应的网络切片的质量和网络切片的质量要求之间的关系。切片管理控制网元根据NS3对应的第三信息，以及预配置策略确定NS3对应的网络切片的质量和网络切片的质量要求之间的关系。
可选的，在一些实施例中，如图10所示，本申请实施例提供的方法还可以包括：
步骤110、切片管理控制网元根据第一信息、第二信息、第三信息、第四信息中的至少一个，控制第一网络切片中的用户接入。
应理解，本申请实施例中控制一个网络切片中的用户接入是指控制该网络切片中接入的用户数或者终端数量。或者该网络切片中接入的一个业务的业务数。
应理解，步骤110中的第一网络切片和步骤101中的至少一个网络切片为同一个网络区域中的网络切片。或者，步骤110中的第一网络切片和步骤101中的至少一个网络切片为同一个网络区域中同一个时间段内的网络切片。该至少一个网络切片可以包括第一网络切片，也可以不包括第一网络切片。
示例性的，本申请实施例中的步骤110具体可以通过以下示例1至示例3中的任一个示例实现：
示例1、切片管理控制网元确定第一网络切片的质量高于第一网络切片的质量要求，切片管理控制网元减少第一网络切片中的用户接入。
应理解，当至少一个网络切片不包括第一网络切片时，第一网络切片的质量和第一网络切片的质量要求之间的关系，可以通过至少一个网络切片的质量和至少一个网络切片的质量要求确定。即通过至少一个网络切片的负载信息，确定可以传输背景流量的时间段。
示例性的，切片管理控制网元确定第一网络切片的质量高于第一网络切片的质量要求，包括：切片管理控制网元确定至少一个网络切片中除第一网络切片外存在任一个网络切片的质量小于任一个网络切片的质量要求，切片管理控制网元确定第一网络切片的质量高于第一网络切片的质量要求。具体切片管理控制网元如何确定第一网络切片的质量与第一网络切片的质量要求之间的关系的过程，参照现有技术。
例如，至少一个网络切片包括：NS1、NS2以及NS3。其中，第一网络切片为NS1，如果切片管理控制网元确定NS2的质量小于NS2的质量要求，则切片管理控制网元确定NS1的质量高于第一网络切片的质量要求。
应理解，当至少一个网络切片包括第一网络切片时，切片管理控制网元确定第一网络切片的质量高于第一网络切片的质量要求，包括：切片管理控制网元根据第一网络切片的第一信息确定第一网络切片的质量。当第一网络切片的质量大于第一网络切片的质量要求时，切片管理控制网元确定第一网络切片的质量高于第一网络切片的质量要求。
应理解，当至少一个网络切片不包括第一网络切片时，切片管理控制网元确定第一网络切片的质量高于第一网络切片的质量要求，包括：切片管理控制网元根据至少一个网络切片的第一信息确定至少一个网络切片的质量。当至少一个网络切片中部分或者全部网络切片的质量低于网络切片的质量要求时，切片管理控制网元确定第一网络切片的质量高于第一网络切片的质量要求。
在一种可选的实现方式中，本申请实施例提供的方法还包括：切片管理控制网元将至少一个网络切片的质量与质量要求的关系发送给接入设备。
例如，在示例1中切片管理控制网元将第一网络切片的质量高于第一网络切片的质量要求的信息发送给接入设备，这样接入设备可以减少为第一网络切片分配的资源。
例如，在示例1中切片管理控制网元将至少一个网络切片中除第一网络切片外其余网络切片的质量低于或等于该其余网络切片的质量要求的信息发送给接入设备，这样接入设备可以增加为其余网络切片分配的资源。
示例2、切片管理控制网元确定至少一个网络切片中除第一网络切片外的任一个网络切片的质量高于任一个网络切片的质量要求，切片管理控制网元增加第一网络切片中的用户接入。
在一种可选的实现方式中，示例2具体可以通过以下方式实现：在至少一个网络切片中除第一网络切片外的任一个网络切片的质量高于任一个网络切片的质量要求的情况下，切片管理控制网元确定第一网络切片中当前的用户接入数小于第二最大注册用户数，切片管理控制网元增加第一网络切片中的用户接入数。
可选的，在至少一个网络切片中除第一网络切片外的任一个网络切片的质量高于任一个网络切片的质量要求的情况下，且切片管理控制网元确定第一网络切片中当前的用户接入数小于第二最大注册用户数等于第二最大注册用户数，切片管理控制网元向接入设备发送至少一个网络切片的质量与质量要求之间的关系。
可选的，第一网络区域中的终端由第一网络切片服务。
可选的，第一网络切片用于传输背景流量。
下述将结合具体实例详细介绍如何确定业务数据的传输策略。
例如，以TA1中具有网络切片1、网络切片2、背景流量传输(Background Data Transfer，BDT)切片为例。如表2所示：策略控制网元首先将业务数据传输需求，即TA1提供给切片管理控制网元。其中，业务数据传输需求中还可以包括：ASP ID、终端的数量(number of UEs)、终端的第一数据量、时间窗。
切片管理控制网元首先获取TA1下面不同时间窗中网络切片1、网络切片2的统计信息(即网络切片1、网络切片2在网络中运行质量)以及配置在切片管理控制网元上的网络切片1、网络切片2的质量要求，确定网络切片1、网络切片2的Slice SLA fulfilment信息，之后，将Slice SLA fulfilment信息反馈给策略控制网元。

Figure PCTCN2019105207-appb-000004
Figure PCTCN2019105207-appb-000005
由表2可以知道，策略控制网元通过网络切片1、网络切片2的Slice SLA fulfilment信息发现，TA1下面00:00-01:00时间段内Slice SLA为Overfitting，即网络在该时间段有空闲资源可用于传输背景流量。策略控制网元将00:00-01:00作为背景流量传输策略，并发送给AF网元。
此外，策略控制网元通过确定网络切片1和网络切片2的网络切片的质量和质量要求之间的关系都超过100％，并且查询AMF确定当前TA 1中BDT切片有3万用户，且网络切片的质量要求中要求BDT切片中的用户数为10万。所以策略控制网元确定BDT切片可以接入更多用户。
示例性的，以图2所示的通信系统应用于如图3所示的5G网络，策略控制网元为PCF网元，切片管理控制网元为NSSF网元，数据分析网元为NWDAF网元、该5G网络还包括：AMF网元、AF网元、NEF网元以及RAN设备，以业务数据为背景流量为例，如图11所示，为本申请实施例提供的一种传输策略确定方法和策略控制方法，该方法包括如下步骤：
步骤201、AF网元向NEF网元发送背景数据传输策略协商建立(Nnef_BDTPNegotiation_Create)服务请求，以使得NEF接收来自AF网元的背景数据传输策略协商建立服务请求。通过背景数据传输策略协商建立服务请求AF网元可以向网络侧请求背景流量传输策略。
其中，背景数据传输策略协商建立服务请求携带业务数据传输需求。其中，业务数据传输需求的内容详见表1，此处不再赘述。
步骤202、NEF网元向PCF网元发送的背景数据传输策略控制建立(Npcf_BDTPolicyControl_Create)服务请求，以使得PCF网元接收来自NEF的背景数据传输策略控制建立服务请求。
其中，背景数据传输策略控制建立服务请求中携带来自AF网元的业务数据传输需求。
步骤203、PCF网元向NSSF网元发送网络切片可用性通知请求，以使得NSSF网元接收来自PCF网元的网络切片可用性通知请求。
其中，网络切片可用性通知请求中携带第二网络区域的标识。
步骤203中PCF网元确定第二网络区域的方式可以参考上述实施例中的描述，此处不再赘述。
可选的，网络切片可用性通知请求中还可以携带：第三时间段、终端对应的第一用户数、终端对应的第一数据量、终端的标识、服务于终端的业务提供服务器对应的应用功能网元的标识(ASP identifier，ASP ID)。这样切片管理控制网元可以根据业务数据传输需求中的信息确定用户传输该业务的网络切片的网络质量要求。
步骤204、NSSF网元向NWDAF网元发送数据分析信息请求，以使得NWDAF网元接收数据分析信息请求。
其中，数据分析信息请求中携带至少一个网络切片的标识信息。应理解，至少一个网络切片为第二网络区域中的网络包括的网络切片。
步骤205、NWDAF网元向NSSF网元发送数据分析信息请求响应，以使得NWDAF网元接收到数据分析信息请求响应。
其中，数据分析信息请求响应中携带第一网络区域中至少一个网络切片中每个网络切片的质量。
步骤206、NSSF网元向PCF网元发送网络切片可用性通知请求响应，其中，网络切片可用性通知请求响应中携带每个网络切片的质量。
步骤207、PCF网元基于第一网络区域中不同时间段内至少一个网络切片中每个网络切片的质量，确定不同时间段内每个网络切片的质量与各自质量要求之间的关系。
步骤208、PCF网元根据不同时间段内每个网络切片的质量与各自质量要求之间的关系，确定背景流量传输策略。
具体的，PCF网元可以根据不同时间段内每个网络切片的质量与各自质量要求之间的关系，将网络切片的质量高于质量要求的时间段确定为背景流量传输策略。
步骤209、PCF网元向NEF网元发送背景流量策略控制建立响应(Npcf_BDTPolicyControl_Create response)。
其中，背景流量策略控制建立响应中携带背景流量传输策略。
步骤210、NEF网元向AF网元发送背景流量协商建立响应(Nnef_BDTPNegotiation_Create response)。
其中，背景流量协商建立响应中携带背景流量传输策略。
应理解，步骤201-步骤210中的至少一个网络切片不包括背景流量切片(BDT切片)。
步骤211、NSSF网元向NWDAF网元发送数据分析信息请求，以从NWDAF网元处获取BDT切片在第一网络区域下不同时间段内的统计信息。
其中，数据分析信息请求中携带第一网络区域的标识、BDT切片的标识信息。
步骤212、NSSF网元接收来自NWDAF网元的数据分析信息请求响应。
该数据分析信息请求响应中携带第一网络区域中BDT切片的满足信息(Statistics Infofmation)。
其中，BDT切片的满足信息包括：BDT切片的标识信息、网络区域、BDT切片中已经传输的背景流量大小(可以是终端级别的)、已经传输的背景流量的终端数目。
步骤213、NSSF网元向至少一个AMF网元发送第一网络区域的标识、BDT切片的标识信息。
步骤214、NSSF网元接收来自至少一个AMF网元的网络切片有效性更新服务操作(Nnssf_NSSAIAvailability_Update)。
其中，网络切片有效性更新服务操作中携带背景流量的切片中当前的注册用户数。
如果NSSF网元通过步骤206确定至少一个网络切片的质量小于质量要求(即Slice SLA fulfilment信息为欠拟合)，则NSSF网元执行下述步骤215。或者执行步骤215 和步骤216。
如果NSSF网元通过步骤206确定至少一个网络切片中任一个网络切片的质量高于该任一个网络切片的质量要求(即任一个网络切片过拟合)，则执行步骤217或步骤218。
步骤215、NSSF网元确定BDT切片的Slice SLA fulfilment信息为overfitting，则NSSF减少BDT切片中的注册用户数。
步骤216、NSSF网元将至少一个网络切片的Slice SLA fulfilment信息和/或BDT切片的Slice SLA fulfilment信息发送给RAN。
应理解，RAN接收到至少一个网络切片的Slice SLA fulfilment信息和/或BDT切片的Slice SLA fulfilment信息之后可以决定资源调度。例如，增加或者减少BDT切片的空口资源调度。
例如，NSSF网元向该RAN对应的至少一个AMF网元发送网络切片可用性通知，其中，网络切片可用性通知中携带第一网络区域中至少一个网络切片的Slice SLA fulfilment信息和/或BDT切片的Slice SLA fulfilment信息。然后至少一个AMF网元通过配置信息更新确认信息(CONFIGURATION UPDATE ACKNOWLEDGE)向RAN发送至少一个网络切片的Slice SLA fulfilment信息和/或BDT切片的Slice SLA fulfilment信息。
具体的，如果RAN确定BDT切片Slice SLA fulfilment信息为overfitting，则增加BDT切片的空口资源调度。
步骤217、如果NSSF网元确定业务数据传输需求中的终端数目大于步骤212中已经传输的背景流量的终端数目，则NSSF网元允许更多的用户接入BDT切片。
应理解，如果任一个网络切片过拟合，且步骤203中终端对应的第一用户数大于步骤212中已经传输的背景流量的终端数目，即任一个网络切片所属的网络资源充足，BDT切片中还可以允许加入用户。
步骤218、如果NSSF网元确定业务数据传输需求中的终端数目等于步骤212中已经传输的背景流量的终端数目，则NSSF网元向RAN发送至少一个网络切片的Slice SLA fulfilment信息和/或BDT切片的Slice SLA fulfilment信息。
应理解，如果NSSF网元确定背景流量传输需求中的终端数目等于步骤212中已经传输的背景流量的终端数目，即虽然当前网络资源充足，但是租户需求的用户数已经全部加入背景流量切片。这种情况，NSSF网元认为BDT切片的Slice SLA fulfilment信息为overfitting，并且为BDT切片分配的空口资源增多。
可选的，RAN接收到至少一个网络切片的Slice SLA fulfilment信息和/或BDT切片的Slice SLA fulfilment信息之后，如果确定BDT切片的Slice SLA fulfilment信息为overfitting可以决定减少BDT切片的空口资源调度。
可选地，NSSF网元在决定BDT切片的Slice SLA fulfilment信息时，也需要参考来自NWDAF网元的BDT切片的统计信息。比如，只有当NSSF网元发现步骤203中业务数据传输需求的终端数目等于步骤212中已经传输的背景流量的终端数目以及背景流量的切片中当前的注册用户数之和时，才会进一步通知RAN减少为BDT切片分配的空口资源。
通过执行步骤211-步骤218，NSSF网元可以控制BDT切片中的用户数，避免对至少一个网络切片的运行质量影响。

步骤401、第一网元确定第一网络区域中第一网络切片的第一信息。
应理解，第一网元确定第一网络区域中的第一网络切片的第一信息应在切片部署初期或者网管新创建该第一网络切片初期。
