Description

一种配置网络切片的方法、装置和系统 技术领域
本发明涉及无线通信技术领域，特别涉及一种配置网络切片的方法、装置和系统。
背景技术
第五代移动通信技术(5th-Generation，5G)系统提出网络切片概念，网络切片可以理解为一种按需网络。一个物理网络可以在逻辑上被划分为多个网络切片，不同的网络切片可以用来承载不同的业务，不同的网络切片按不同需求可以进行物理隔离，也可以进行逻辑隔离，可以认为一个网络切片是完成某个(或某些)业务所需的网络功能及资源的组合，是一个完整的逻辑网络。
不同的租户可以通过租用网络运营商的网络来部署自己的业务，网络运行商则可以将网络以网络切片的形式提供给租户。网络运营商在获取到租户的业务网络需求后，可以根据网络需求确定相应的网络切片的需求信息，需求信息可以包含业务类型信息或者网络切片类型信息、业务服务等级协议(Service-Level Agreement，SLA)或者网络关键绩效指标(Key Performance Indicator，KPI)等信息。之后，网络运营商的技术人员可以根据上述网络切片的需求信息，人工在核心网(Core Network，CN)、接入网(Access Network，AN)和传输网(Transport Network，TN)各个子网管理单元上的进行网络资源配置，从而配置相应的网络切片。
在实现本发明的过程中，发明人发现上述处理至少存在以下问题：
在配置网络切片时，人工配置网络资源的方式会消耗技术人员大量的时间和精力，这样，配置网络切片的效率较低。
发明内容
为了解决背景技术中的问题，本发明实施例提供了一种共享下行频谱的方法和装置。所述技术方案如下：
第一方面，提供了一种配置网络切片的方法，该方法包括：
在配置网络切片的过程中，网络切片管理单元可以先获取或确定网络切片的子网对应的网络资源信息，然后以子网管理请求的方式将子网对应的网络资源信息发送给各个子网的子网管理单元，以使子网管理单元根据上述子网对应的网络资源信息进行子网的配置处理。
本公开实施例所示的方案，由网络切片管理单元获取或者确定子网对应的网络资源信息，并将该网络资源信息发送个子网管理单元，从而子网管理单元可以根据网络资源信息配置子网。在整个配置网络切片的过程中，无需技术人员人工参与，可以仅通过网络切片管理单元和子网管理单元等设备自行完成配置网络切片的，从而可以提高配置网络切片的效率。
在一种可能的实现方式中，网络切片管理单元可以接收BSS或Customer或SM发送的网络切片的管理请求，然后获取其中携带的网络切片的需求信息，进而可以再基于网络切片的 需求信息，确定出网络切片包括的子网所对应的网络资源信息。

下面将结合具体实施方式，对图2所示的处理流程进行详细的说明，内容可以如下：
步骤201，网络切片管理单元确定或获取子网对应的网络资源信息，向子网管理单元发送子网管理请求。
其中，网络切片管理单元可以是上述CDM；子网可以包括TN子网、AN子网和CN子网中的至少一个；子网对应的网络资源信息可以用于子网管理单元配置子网，子网对应的网络资源信息还可以称为网络切片网络资源信息，网络资源信息，网络切片的传输资源信息，传输 资源信息，子网连接信息，网络连接信息，子网连接点，子网的IP地址，或者子网对应的传输资源信息等；这里的子网对应的网络资源信息可以是子网包括的网络组件(e.g.网络功能)的连接信息；子网管理请求中携带有子网的网络资源信息；这里的子网管理请求可以是以下管理请求中的任意一个：创建请求、实例化请求、配置请求等。
在实施中，在配置网络切片的过程中，网络切片管理单元可以先获取网络切片对应的子网的网络资源信息，然后向子网管理单元发送携带有子网的网络资源信息的子网管理请求，这样，子网管理单元在接收到上述子网管理请求后，可以根据其中携带的子网的网络资源信息，配置相应子网，此处，子网也可以称为子网络切片，一个完整的网络切片可以由多个不同的子网组成。
步骤202，第一子网管理单元确定或获取子网对应的网络资源信息，根据子网的网络资源信息配置子网。
其中，第一子网管理单元可以是TN子网管理单元。
在实施中，第一子网管理单元可以获取子网对应的网络资源信息，然后根据子网对应的网络资源信息配置相应的子网，即在相应的子网的组件中配置网络资源信息。如果接收到的子网管理请求是子网创建或者实例化请求，则先根据子网对应的网络资源信息创建或者实例化子网，然后根据子网对应的网络资源信息配置相应的子网。此处不对子网的名称进行限定，该子网可以称为第一子网或者TN子网等。
在不同实施例中，步骤202可以发生在步骤201之后，也可以发生在步骤201之前。
步骤203，第二子网管理单元获取子网对应的网络资源信息，根据子网的网络资源信息配置子网。
其中，第二子网管理单元可以是CN/AN子网管理单元。
在实施中，第二子网管理单元可以获取子网对应的网络资源信息，然后根据子网对应的网络资源信息配置相应的子网，即在相应的子网的组件中配置网络资源信息。如果接收到的子网管理请求是子网创建或者实例化请求，则根据子网对应的网络资源信息创建或者实例化子网，后根据子网对应的网络资源信息配置相应的子网。此处不对子网的名称进行限定，该子网可以称为第二子网或者CN/AN子网等。
在不同实施例中，步骤203可以发生在步骤202之后，也可以与步骤202同时发生。
可选的，上述步骤201至步骤203的流程根据不同的配置方式，具体可以有以下几个可行的处理流程：
流程一，如图3所示：
步骤301，网络切片管理单元接收网络切片的管理请求。
其中，网络切片的管理请求携带有网络切片的需求信息。网络切片的需求信息是指用于确定一个网络切片的必要信息。例如，网络切片的需求信息可以包括以下部分或全部内容：网络切片的类型(例如，增强移动宽带(enhanced Mobile Broadband，eMBB)、海量机器类通信(massive Machine Type Communication，mMTC)、高可靠低时延通信(Ultra-Reliable and Low Latency Communication，URLLC)等)、业务的SLA要求或网络的KPI等。其中，业务的SLA要求或网络的KPI可以包括以下至少一项：时延(latency)、上报成功率(report success ratio)、下发成功率(command success ratio)、覆盖(coverage)、容量(capacity)、 可靠性(reliability)或吞吐量(throughput)。其中，上报成功率可以指上行包发送成功的比例；下发成功率可以指下行包发送成功的比例；覆盖可以指终端的分布区域；容量可以指可容纳的终端数量。
在实施中，当需要进行某项业务的配置网络切片的时，用户可以通过系统提供的可操作界面向网络切片管理单元发送网络切片的管理请求，或者由BSS向网络切片管理单元发送网络切片的管理请求，或者SM接收到相关租户的业务需求后，将该业务需求转换为相应的网络切片的需求信息，从而向网络切片管理单元发送网络切片的管理请求。该网络切片的管理请求中可以携带网络切片的需求信息或指示信息，该管理请求用于指示网络切片管理单元根据网络切片的需求信息配置相应的网络切片。这里的管理请求可以是以下请求中的任一种：网络切片创建请求，网络切片配置请求，网络切片分配请求，网络切片实例化请求或者业务请求。
步骤302，网络切片管理单元根据网络切片的需求信息，确定子网对应的网络资源信息。
在实施中，网络切片管理单元接收到网络切片的管理请求后，可以根据其中携带的网络切片的需求信息确定网络切片包括的子网所对应的网络资源信息。
具体的，网络切片管理单元根据网络切片的需求信息确定子网对应的网络资源信息的方式多种多样，如下给出了几种可行的方式：
方式一：网络切片管理单元根据网络切片的需求信息确定网络切片模板，获取网络切片模板中记录的子网对应的网络资源信息。
其中，网络切片模板用于创建或者实例化网络切片实例，本实施例不对其名称进行限定，还可以称为网络切片描述符、网络切片蓝图等。
在实施中，网络切片管理单元获取到网络切片的需求信息后，可以根据该需求信息在预先存储有网络切片模板的数据库中确定相应的网络切片模板，然后获取在网络切片模板中记录的网络切片所属子网对应的网络资源信息。
方式二，网络切片管理单元获取网络切片的需求信息中包含的子网对应的网络资源信息；
在实施中，网络切片的需求信息中可以记录有网络切片所属子网对应的网络资源信息，故而，网络切片管理单元可以直接获取网络切片需求信息中包含的子网对应的网络资源信息。
方式三，网络切片管理单元根据网络切片的需求信息，在预先存储的网络资源信息列表中查询子网对应的网络资源信息。
在实施中，虚拟资源管理单元(如NFVO，VNFM,VIM等)可以预先同步各种网络资源到网络切片管理单元，网络切片管理单元则可以将不同网络切片的需求信息与不同网络资源信息对应存储，生成网络资源信息列表。这样，网络切片管理单元在获取到网络切片的需求信息，则可以在上述网络资源信息列表中查询子网对应的网络资源信息。
方式四，网络切片管理单元根据网络切片的需求信息，从虚拟资源管理单元处获取网络切片的需求信息对应的网络资源信息。
