Description

一种信息配置方法和管理单元
本申请要求于2017年08月04日提交中国专利局、申请号为201710660876.2、申请名称为“一种信息配置方法和管理单元”的中国专利申请的优先权，以及于2017年08月11日提交中国专利局、申请号为201710687514.2、申请名称为“一种信息配置方法和管理单元”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
本发明实施例涉及通信领域，尤其涉及一种信息配置方法和管理单元。
背景技术
网络虚拟化加快了网络业务的发展趋势。相对传统通信业务，运营商不得不面对更加动态变化的市场，层出不穷、差异化的新需求。如何利用现有的网络资源，快速的响应企业与企业(Business-to-Business，B2B)和商对客(Business-to-Customer，B2C)的业务需求，及时提供新业务的上线和开通，是运营商面临的主要竞争压力。
业务编排可以实现业务敏捷需求：用户的业务请求输入业务编排器后，业务编排器自动对业务请求进行分解，最终分解为多个网元的创建请求和配置数据等，编排网络，缩短投入市场(Time To Market，TTM)时间。
在支持当前商业模式演变的基础上，下一代网络将扩展支持新的不同类型的客户和合作伙伴。运营商将支持垂直产业,促进产业和行业的互动过程。伙伴关系将建立在多个层面，从共享基础设施、开放特定网络功能，到将合作伙伴强大丰富的软件能力集成到下一代网络系统提供端到端服务。建立多层面的合作关系，灵活性和功能嵌入是非常重要的。网络切片将是下一代网络满足不同行业、不同用户对网络具有超特殊需求时的重要技术手段。
传统技术方案中，如图1所示，用户设备(User Equipment，UE)第一次接入(注册请求)接入网，接入网(Access Network，AN)转发相应注册请求到默认(Default)接入管理单元(Access Management Function，AMF)，Default AMF转发相应注册请求到网络选择功能单元(Network Slice Selection Function，NSSF)，NSSF、default AMF或NRF根据注册请求选择AMF群(Group)，并将所选择的接入管理单元组的标识返回给AN，AN从接入管理单元组选择具体的AMF instance(实例)，并发送会话建立请求到具体的AMF instance。
但是，网络中通常包括多个接入管理单元组，而传统技术方案中，并未给出NSSF、default AMF或NRF如何选择接入管理单元组，这样可能存在无法选择接入管理单元组或者NSSF、default AMF或NRF所选择的接入管理单元组不满足业务的需求。
发明内容
本发明实施例提供一种信息配置方法和管理单元，用以通过为NSSF、default AMF或NRF配置接入管理单元AMF组信息与网络切片信息的关联关系，使得NSSF、default AMF或NRF可以选择满足UE的需求的AMF组。
第一方面，本申请提供了一种信息配置方法，包括：第一管理单元确定接入管理单元AMF组信息与网络切片信息的关联关系，该关联关系用于指示(第一网络单元，例如NSSF、default AMF或NRF)根据AMF组信息选择网络切片信息或者根据网络切片信息选择AMF组信息，然后第一管理单元向第一网络单元或第一网络单元的管理单元发送包括该关联关系的第一消息。或，第一管理单元保存关联关系。可选的，第一管理单元可以既向第一网络单元发送该关联关系，也可以将该关联关系保存在第一管理单元中。
本申请提供一种信息配置方法，通过第一管理单元确定AMF组Group信息与网络切片信息之间的关联关系，以及将确定的AMF组Group信息与网络切片信息之间的关联关系通过第一消息(例如，配置消息，网络切片请求消息)发送给第一网络单元(例如，网元)或第一网络单元的管理单元(例如，用于管理网元的NSSMF)，由于关联关系用于指示根据AMF组信息选择网络切片信息，或者根据网络切片信息选择AMF组信息，因此，在一个网络中包括多个AMF组时，通过第一管理单元确定的关联关系，可以使得最终被配置该关联关系的功能单元(例如，第一管理单元为子网切片管理单元(Network Slice Subnet Management Function，NSSMF)，第一网络单元为默认AMF时)，可以针对相应的UE发起的业务请求选择有效的AMF组，从而使得所选择的AMF组满足UE的业务请求。
在一种可能的设计中，第一管理单元确定接入管理单元AMF组信息与网络切片信息的关联关系之前，本申请提供的方法包括：第一管理单元接收网络需求信息(例如，网络切片需求信息或者网络切片子网需求信息)，第一管理单元确定接入管理单元AMF组信息与网络切片信息的关联关系，包括：第一管理单元根据网络需求信息确定AMF组信息与网络切片信息的关联关系。在这种设计中，第一管理单元可以根据网络需求信息将已有的网络切片信息与AMF组信息关联，也可以根据网络需求信息创建满足要求的网络切片信息，并将其与已有的满足网络需求信息的AMF组信息关联，或者根据网络需求信息创建满足要求的AMF组信息，并将其与已有的满足网络需求信息的网络切片信息关联，又或者根据网络需求信息创建满足要求的AMF组以及网络切片，并将创建的满足要求的AMF组以及网络切片关联。这样使得关联关系的确定是基于第三方发送的网络需求信息的触发产生，从而可以使得所确定的关联关系满足UE需求。
在一种可能的设计中，第一管理单元确定接入管理单元AMF组信息与网络切片信息的关联关系，包括：第一管理单元接收AMF组信息与网络切片信息之间的关联关系，以确定AMF组信息与网络切片信息的关联关系。通过第一管理单元接收第三方发送的关联关系，可以降低第一管理单元的处理负担。在这种设计中第一管理单元可以通过第三方(例如，第二管理单元)获取AMF组信息与网络切片信息之间的关联关系，例如，可以从第三方发送的配置消息中确定AMF组信息与网络切片信息之间的关联关系，可以适用于第一管理单元为NSSMF，第二管理单元为网络切片管理单元(Network Slice Management Function，NSMF)的网络架构中。
在一种可能的设计中，AMF组信息包括以下中的任意一个：AMF组的标识，AMF组的管理对象标识和AMF组的名称。其中，AMF组的标识用于识别AMF组，AMF 组的管理对象标识用于识别AMF组的管理对象。
在一种可能的设计中，网络切片信息包括以下任一项或多项：网络切片实例标识，网络切片实例管理对象标识，网络切片子网实例标识，网络切片子网管理对象标识，网络切片选择辅助信息S-NSSAI，网络切片类型，服务类型，租户的标识以及公用陆地移动通信网(Public Land Mobile Network，PLMN)，租户的标识用于唯一租户。上述仅是对网络切片信息内容的一些列举，在具体实现中还可以存在除上述所列举的信息之外的其余信息。
在一种可能的设计中，第一管理单元保存所述关联关系，包括以下的任意一种：第一管理单元在AMF组或者AMF组管理对象中配置网络切片信息；第一管理单元在网络切片或者网络切片管理对象中配置AMF组信息；第一管理单元在网络切片子网或者网络切片子网管理对象中配置AMF组信息。
在一种可能的设计中，第一管理单元保存关联关系，包括以下的任意一种：第一管理单元在AMF组或者AMF组管理对象中配置所述网络切片信息；第一管理单元在网络切片或者网络切片管理对象中配置AMF组信息；第一管理单元在网络切片子网或者网络切片子网管理对象中配置AMF组信息。
第二方面，本发明实施例提供一种信息配置方法，包括：第一管理单元确定接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间具有的关联关系中的至少一个关联关系，其中，第一AMF为AMF组包括的多个AMF中的至少一个AMF；第一管理单元向第二网络单元(例如，gNB)发送包括至少一个关联关系的第一消息；或者，第一管理单元保存至少一个关联关系。这样可以使得被配置至少一个关联关系的第二网络单元(例如，基站)确定第一AMF或S-NSSAI与接入管理单元组之间的归属关系。可以理解的是，本申请中第一管理单元确定接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系可以在第一方面所描述的确定接入管理单元AMF组与多个网络切片信息中至少一个网络切片信息之间的关联关系之后执行，也可以单独执行，本申请对此不进行限定。也即本申请中第一管理单元可以只确定接入管理单元AMF组网络切片信息之间的关联关系或只确定接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和S-NSSAI之间的关联关系中的至少一个关联关系，当然，也可以在既确定AMF组信息与网络切片信息之间的关联关系，又确定AMF组信息与第一AMF信息之间的关联关系和AMF组和S-NSSAI之间的关联关系中的至少一个关联关系，这样不仅可以使得第一网络单元(例如，网元)根据被配置的关联关系选择出满足UE需求的AMF组，且可以使得被配置至少一个关联关系的第二网络单元确定出AMF或S-NSSAI与接入管理单元组之间的归属关系。
本申请提供一种信息配置方法，通过第一管理单元(例如，可以是NSSMF)确定接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和S-NSSAI之间的关联关系中至少一个关联关系，然后通过第一管理单元将该至少一个关联关系发送给第二网络单元(例如，gNB)，由于在实际过程中，第二网络单元并不具有上述至少一个关联关系，因此，通过为第二网络单元配置上述至少一个关联关 系，可以使得第二网络单元根据被配置的至少一个关联关系确定满足UE需求的AMF转发UE的业务请求信息。
在一种可能的设计中，第一管理单元确定接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系之前，本申请提供的方法包括：第一管理单元接收网络需求信息(例如，网络切片需求信息或者网络切片子网需求信息)；第一管理单元确定AMF组信息和第一AMF信息之间的关联关系和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系，包括：第一管理单元根据网络需求信息，确定接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系。在这种实现方式中第一管理单元可以基于网络需求信息的触发确定至少一个关联关系，从而使得在确定至少一个关联关系时，不仅可以将已有的AMF组信息和网络切片选择辅助信息S-NSSAI关联，以确定AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系，具有的AMF组信息和第一AMF组信息之间的关联关系，而且还可以在不具有满足网络需求信息的AMF组信息时，创建满足网络需求信息的AMF组信息，并将其与S-NSSAI和第一AMF信息中的至少一项关联，或者在不存在满足网络需求信息的第一AMF和S-NSSAI中的至少一项时，创建第一AMF和S-NSSAI并将其与AMF组信息关联，从而使得被配置至少一个关联关系的第二网络单元可以更加准确的选择AMF以转发UE的业务请求。
在一种可能的设计中，第一管理单元确定接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系，包括：第一管理单元接收AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和S-NSSAI之间的关联关系中的至少一个关联关系，以确定AMF组信息和第一AMF信息之间具有的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间具有的关联关系中的至少一个关联关系。在这种方式下，第一管理单元可以根据第三方发送的至少一个关联关系，将具有的AMF组和第一AMF关联，或者将具有的AMF组与S-NSSAI关联。
在一种可能的设计中，第一管理单元确定接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系，包括：第一管理单元根据AMF组信息确定S-NSSAI，并将确定的S-NSSAI与AMF组信息关联，或者根据AMF组信息确定第一AMF，并将确定的第一AMF与AMF组信息关联；或者，第一管理单元根据第一AMF确定AMF组信息，并将确定的AMF组信息与第一AMF关联，第一管理单元根据S-NSSAI确定AMF组信息，并将确定的AMF组信息与S-NSSAI关联，在这种实现方式中，第一管理单元可以自主的确定接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系。
在一种可能的设计方式中，第一管理单元确定接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的 关联关系中的至少一个关联关系之后，本发明实施例提供的方法还包括：第一管理单元确定第二网络单元不属于第一管理单元的管理范围时，第一管理单元向第二管理单元发送包括至少一个关联关系的第二消息，该第二管理单元用于根据第二消息确定为第二网络单元配置至少一个关联关系的目标管理单元。由于在实际网络架构中，第二网络单元可能不属于第一管理单元的管理范围，因此，通过将至少一个关联关系发送给第二管理单元，可以使得第二管理单元通过选择目标管理单元(可以理解的是，第二管理单元中具有目标管理单元和第二网络单元之间的关联)为第二网络单元配置接入管理单元AMF组和第一AMF之间的关联关系以及接入管理单元组和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一项，以使得第二网络单元可以选择满足UE需求的AMF转发UE的业务请求信息。
在一种可能的设计中，本申请中的第一消息还包括：AMF组信息和网络切片信息之间的关联关系，因此，在发送第一消息之前，第一管理单元中还具有AMF组信息和网络切片信息之间的关联关系，通过在一次信息交互中既发送至少一个关联关系，又发送关联关系，可以减少第一管理单元和第二网络单元之间的多次交互。
在一种可能的设计中，第一管理单元保存至少一个关联关系，包括以下任一项：第一管理单元在第二网络单元或第二网络单元管理对象中配置AMF组信息和S-NSSAI的关联关系；第一管理单元在第二网络单元或第二网络单元管理对象中配置AMF组信息和第一AMF信息的关联关系。
相应的，本申请还提供了一种信息配置装置，该装置可以实现第一方面或第二方面所描述的一种信息配置方法。例如，该装置可以是管理单元，其可以通过软件、硬件、或者通过硬件执行相应的软件实现上述信息配置方法。
在一种可能的设计中，该装置(即管理单元)可以包括处理器和存储器。该处理器被配置为支持该装置执行上述第一方面方法中相应的功能。存储器用于与处理器耦合，其保存该装置必要的程序指令和数据。另外该装置还可以包括通信接口，用于支持该装置与其他网元之间的通信，该通信接口可以是收发器。

具体实施方式
在介绍本申请提供的一种信息配置方法和管理单元之前，首先介绍本申请中涉及的部分术语：
网络切片(Network Slice，NS)：是保证承载业务能达成服务水平协议(Service level requirement，SLR)要求的通信资源，也可以认为是完成某个Service或某些Service所需的网络功能及通信资源的组合。这些通信资源可以按不同需求，进行硬隔离(物理隔离)，也可以软隔离(逻辑隔离)。可以认为一个网络切片是完成某个(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。
业务或者服务(Service)：是一组用户能享有的指定SLR的通信业务，如移动宽带(mobile broadband，MBB)，语音，物联网(Internet of Things，IOT)：例如，智能停车，智能抄表等。
端到端(End to End，E2E)Network Slice：网络切片指的是整个系统设计的概念包括核心网(Core Network，CN)和无线接入网(Radio Access Network，RAN)。
租户(Tenant)：运营商网络的租用者，比如电力公司租用运营商的网络部署智能抄表业务，则电力公司可以为运营商的一个租方。
本申请描述的网络架构以及业务场景是为了更加清楚的说明本申请的技术方案，并不构成对本申请提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请提供的技术方案对于类似的技术问题，同样适用。
本申请提供的技术方案可以应用于网络管理系统，在图1所示网络架构的基础上，本申请的方案引入了逻辑单元：具体的，如图2所示，引入了第一管理单元和第一网络单元的管理单元。又一方面，本申请在图1所示的网络结构的基础上引入了第一管理单元，第一网络单元可以理解为如图3所示的网元，第二管理单元，以及第二网络单元(图3中未示出)，具体架构如图3所示。
可选的，本申请中的第一管理单元可以为网络切片管理单元(Network Slice Management Function，NSMF)或子网切片管理单元(Network Slice Subnet Management Function，NSSMF)。例如，在图2所示的架构中，第一管理单元为NSMF，在图3所示的架构中，第一管理单元为NSSMF。
综上所述，第一管理单元可以为NSMF和NSSMF，第一网络单元可以为NSSF,default AMF,NRF，第一网络单元的管理单元可以为NSSMF，第二网络单元可以为网络设备，例如，gNB，第二网络单元的管理单元可以为NSSMF。
具体的，如图2所示，当第一管理单元为NSMF时，NSMF可以为第一网络单元(例如，网元)或第一网络单元的管理单元(例如，NSSMF)发送关联关系。
如图3所示，当第一管理单元为NSSMF时，NSSMF可以为第一网络单元(例如，网元)发送关联关系。
与之类似，本申请中的第一管理单元为NSMF时，NSMF可以向第二网络单元或第二网络单元的管理单元发送至少一个关联关系。
当第一管理单元为NSSMF时，NSSMF可以向第二网络单元发送至少一个关联关系。
本申请中的第一网络单元可以为网元，第一网络单元的管理单元用于对第一网络单元进行管理，例如，可以为子网切片管理单元NSSMF，第一网络单元可以为网元，例如，网络选择功能单元(Network Slice Selection Function，NSSF)、网络功能存储单元(NF Repository Function，NRF)以及默认AMF中的至少一项。具体的，在不同架构中第一网络单元的作用有所差异，下述将结合具体实施例进行介绍：
本申请中，可以将网络切片管理单元设置为一个单独的功能实体，也可以将网络切片管理单元设置为其它功能实体的功能模块，还可以将网络切片管理单元的功能集成在其他功能实体中。类似的，本申请中，可以将子网切片管理单元设置为一个单独的功能实体，也可以将子网切片管理单元设置为其它功能实体的功能模块，还可以将子网切片管理单元的功能集成在其他功能实体中。进一步地，网络切片管理单元和子网切片管理单元可以合并为一个合设实体，该合设实体具备网络切片管理单元的功能和子网切片管理单元的功能。例如，该合设实体可以称之为业务与网络编排单元，可 以理解的是，该合设实体还可以有其他名称，本申请并不限定。类似的，在合设实体的情况下，本申请中，可以将合设实体设置为一个单独的功能实体，也可以将合设实体设置为其它功能实体的功能模块，还可以将合设实体的功能集成在其他功能实体中。
上述网络切片管理单元包括但不限于接收网络切片实例(Network Slice Intance，NSI)请求消息，该NSI请求消息中携带NSI网络需求信息，具体的，租户业务提供商(Communication Service Provider，CSP)向租户业务管理单元(Service Management Function，CSMF)发送业务请求消息，该业务请求消息携带(业务需求信息)，CSMF在接收到该业务请求消息后，CSMF将业务需求转换为网络需求(例如，CSMF)。以及配置接入管理单元(Access and Mobility Management Function，AMF)组(接入管理单元组也可以称之为移动性管理单元组，即AMF Group)与网络切片信息之间的关联关系，以及将AMF组信息和网络切片信息之间的关联关系发送给子网切片管理单元或者发送给网元，以及将AMF组信息与该AMF组包括的一个或多个AMF信息关联，得到AMF组信息和每个AMF信息之间的关联关系，以及将AMF组信息与S-NSSAI关联，并将得到的AMF组信息与每个AMF信息之间的关联关系以及AMF组信息与S-NSSAI之间的关联关系发送给NSSMF，此外，NSMF还用于将网络请求消息转化为子网的需求信息，并将子网的需求信息发送给NSSMF，以使得NSSMF根据子网的需求信息确定AMF组信息与AMF组包括的一个或多个AMF信息之间的关联关系以及根据网络需求信息确定网络切片信息(又可以称为AMF组选择信息)与AMF组信息之间的关联关系以及确定AMF组信息与S-NSSAI之间的关联关系。
上述子网切片管理单元包括但不限于接收NSMF发送的携带网络切片信息与接入管理单元组之间关联关系的第一消息，将网络切片信息与接入管理单元组信息之间关联关系配置给第一网络单元(例如，网元)或者根据NSMF发送的子网的需求信息确定接入管理单元组信息与网络切片信息之间的关联关系，以及确定接入管理单元组信息与接入管理单元组包括的一个或多个AMF中每个AMF信息之间的关联关系，以及接入管理单元组信息与S-NSSAI之间的关联关系，以及将网络切片信息与接入管理单元组信息之间的关联关系配置给第一网络单元，以及将接入管理单元组信息与每个AMF信息之间的关联关系，接入管理单元组信息与网络切片信息之间的关联关系配置给第二网络单元(例如，网络设备可以为下一代基站(Next Generation Node B，gNB)。
可选的，本申请中的网元包括NSSF、NRF以及默认AMF中的至少一项。
其中，NSSF用于存储一个或多个接入管理单元组中每个接入管理单元组与各自对应的网络切片信息之间的关联关系，以及在接收到默认AMF转发的UE的注册请求时，根据注册请求所携带的需求信息，选择满足该注册请求的接入管理单元组，并将满足注册请求的接入管理单元组的信息通过默认AMF转发给AN。此外，NSSF还用于存储多个接入管理单元组中每个接入管理单元组与各自包括的一个或多个AMF之间的关联关系，以及每个接入管理单元组与各自对应的S-NSSAI之间的关联关系。
NRF的作用用于服务化网络架构下NF信息(例如，NF实例的信息，NF实例所述的切片信息，NF实例相应的切片选择辅助信息等)的存储和发现。
默认AMF用于对用户设备进行鉴权、授权，对用户设备的移动性进行管理。当然，NRF和默认AMF均可以用于存储一个或多个接入管理单元组中每个接入管理单 元组与各自对应的网络切片信息之间的关联关系，多个接入管理单元组中每个接入管理单元组与各自包括的一个或多个AMF之间的关联关系，以及多个接入管理单元组中每个接入管理单元组与各自对应的S-NSSAI之间的关联关系。
本申请中的网络设备可以为基站，通过向gNB配置每个接入管理单元组和各自包括的每个AMF之间的关联关系，使得gNB可以根据被配置的每个接入管理单元组和各自包括的每个AMF之间的关联关系，从而选择满足UE需求的AMF转发UE的业务请求信息。
如图2和图3所示，图2和图3示出了本申请提供的几种可能的网络架构示意图，在这几种可能的架构图中AN、SMF以及NSSF的功能均与图1相同，可以参照图1中的介绍，后续不再赘述。下面介绍图2和图3所示的网络架构中，NSMF与NSSMF的设置情况。
具体的，当本申请提供的方法应用于如图2所示的网络架构时，第一管理单元可以是NSMF，第一网络单元的管理单元可以是NSSMF，在图2中NSMF也可以直接为网元配置AMF组信息与网络切片信息之间的关联关系。
当本申请提供的方法应用于如图3所示的网络架构时，第一管理单元可以是NSSMF，第一网络单元可以是NSSF、NRF以及默认AMF中的至少一项。第二管理单元可以是NSMF，第二网络单元可以是NF。
需要说明的是，本申请中的NSMF还可以是网络管理单元(Network Management，NM)。NSSMF为NSSF、NRF或默认AMF配置AMF组信息与网络切片信息之间的关联关系可以通过网元管理(Element Manager，EM)或网络功能管理(Network Function Manager，NFM)单元来配置。
当然，当本申请提供的方法应用于如图3所示的网络架构时，第一管理单元可以是NSSMF，第一网络单元可以为NSSF、NRF以及默认AMF中的至少一项，第二管理单元可以是NSMF。也即NSSMF可以直接给NSSF、NRF以及默认AMF中的至少一项配置接入管理单元组与网络切片信息之间的关联关系。
下面结合图4至图6对本申请提供的方案做进一步说明。
图4为本申请提供的一种信息配置方法的流程示意图。图4所示的方法可以应用于图2所示的网络架构。如图4所示，本申请提供的一种信息配置方法，包括以下步骤：
S101、NSMF确定AMF组信息与网络切片信息之间的关联关系，其中，该关联关系用于指示根据AMF组信息从多个网络切片中确定网络切片信息所指示的网络切片或者根据网络切片信息从多个AMF组中确定AMF组信息所指示的AMF组。
可选的，本申请中的接入管理单元AMF组信息为多个接入管理单元AMF组中的至少一个AMF组的信息。网络切片信息为多个网络切片信息中的至少一个网络切片信息。
本发明实施例中的AMF组信息可以为AMF组的标识或AMF组的管理对象标识，例如，AMF组的标识可以为AMF组的名或者产品编号，AMF组的管理对象标识可以为AMF的管理对象的名称或者产品编号。
可选的，本申请中的网络切片信息包括以下任一项或多项：网络切片实例标识， 网络切片实例管理对象标识，网络切片子网实例标识，网络切片子网管理对象标识，网络切片选择辅助信息S-NSSAI，网络切片类型，服务类型，租户的标识以及公用陆地移动通信网PLMN。其中，网络切片实例标识用于识别网络切片实例，网络切片实例管理对象标识，用于识别网络切片实例管理对象，租户的标识用于识别租户。
作为一种可能的实现方式，NSMF可以将接入管理单元AMF组的标识与网络切片信息关联，以作为接入管理单元AMF组信息与网络切片信息之间的关联关系。
本申请中的接入管理单元组和网络切片信息可以满足同一个业务需求。当网络切片信息具有多个时，本申请中的一个AMF组信息还可以与两个或两个以上的网络切片信息关联，即在此种情况下，网络切片信息可以为至少两个网络切片信息中的两个或两个以上。
可以理解的是，本申请中的AMF组与网络切片信息之间的关联关系也可以称之为：网络切片选择辅助信息。
S102、NSMF向NSSMF发送第一消息，该第一消息包括AMF组与网络切片信息之间的关联关系，其中，NSSMF用于为网元配置AMF组与网络切片信息之间的关联关系。
可选的，本申请中的第一消息可以为配置消息，也可以为切片请求消息，也可以为网络请求消息。
或者，可选的，本申请中NSMF将该关联关系保存。具体的，NSMF保存关联关系，包括以下的任意一种：NSMF在AMF组或者AMF组管理对象中配置网络切片信息；NSMF在网络切片或者网络切片管理对象中配置所述AMF组信息；NSMF在网络切片子网或者网络切片子网管理对象中配置AMF组信息。
本申请提供一种信息配置方法，通过第一管理单元确定AMF组Group信息与网络切片信息之间的关联关系，以及将确定的AMF组Group信息与网络切片信息之间的关联关系通过第一消息(例如，配置消息，网络切片请求消息)发送给第一网络单元或第一网络单元的管理单元，由于关联关系用于指示根据AMF组信息选择网络切片信息，或者根据网络切片信息选择AMF组信息，因此，在一个网络中包括多个AMF组时，通过第一管理单元确定的关联关系，可以使得最终被配置该关联关系的第一网络单元(例如，第一管理单元为子网切片管理单元(Network Slice Subnet Management Function，NSSMF)，第一网络单元为默认AMF时)，可以针对相应的UE发起的业务请求选择有效的AMF组，从而使得所选择的AMF组满足UE的业务请求。
其中，本申请中的网元可以为NSSF、NRF以及默认AMF中的至少一项。
为了使得网元可以根据UE的业务请求确定出满足UE业务需求的AMF组，如图5所示，本申请提供的方法还包括：
S103、NSSMF将AMF组信息与网络切片信息之间的关联关系发送给网元。
可以理解的是，通过步骤S103即可以实现由NSSMF为网元配置AMF组信息与网络切片信息之间的关联关系的过程，这样网元在接收到UE的注册请求时，便可以根据被配置的关联关系确定满足UE需求的接入管理单元组，与现有技术中网元在接收到UE的注册请求时随机选择AMF组相比，可以使得所选择的AMF组满足UE的需求。
由于在实际过程中，NSMF中可能具有接入管理单元组以及网络切片信息，但是却无二者之间的关联关系。又或者，NSMF具有满足业务需求的接入管理单元组，但是却不具有满足业务需求的网络切片信息，此时需要创建满足业务需求的网络切片信息，又或者，NSMF中可能并不具有满足业务需求的网络切片信息和网络切片信息，由于上述场景在具体实现中存在差异，因此以下将分别介绍：
可选的，在一种可能的实现方式中，本申请中的步骤S101可以通过以下方式实现：
S1011、NSMF将至少一个接入管理单元组中的一个AMF组(例如，第一AMF组)与至少一个网络切片信息中的一个网络切片信息(例如，第一网络切片信息)关联，以确定AMF组信息与网络切片信息之间的关联关系。这样可以使得NSMF自己确定将已有的AMF组和与其对应的网络切片信息关联。
具体的，NSMF可以将同一类型或者满足同一业务需求的AMF组与至少一个网络切片信息中的一个网络切片信息关联。
作为一种可能的实现方式，NSMF将AMF组的标识和与该AMF组对应的至少一个网络切片信息中的一个网络切片信息关联，以确定AMF组与网络切片信息之间的关联关系。
作为一种可能的实现方式，本申请中的步骤S1011可以通过以下方式实现：
S1011a、NSMF根据AMF组信息从至少一个网络切片信息中确定第一网络切片信息，并将确定的第一网络切片信息与AMF组信息关联，以确定AMF组信息与网络切片信息之间的关联关系。
在这种实现方式中，NSMF中可以具有网络切片信息和AMF组，也可以仅具有AMF组，这样NSMF可以根据已有的AMF组信息确定相应的第一网络切片信息，从而确定接入管理单元组与网络切片信息之间的关联关系。
作为一种可能的实现方式，本申请中的步骤S1011可以通过以下方式实现：
S1011b、NSMF根据至少一个网络切片信息中的一个网络切片信息(例如，第一网络切片信息)从至少一个AMF组中确定第一AMF组信息(其中，第一接入管理单元组信息可以为第一接入管理组的标识)，并将确定的第一AMF组与至少一个网络切片信息中的一个网络切片信息关联，从而确定第一AMF组与至少一个网络切片信息中的一个网络切片信息之间的关联关系。
通过步骤S1011a或S1011b来实现步骤S1011，可以使得NSMF灵活地确定第一网络切片信息与第一AMF组之间的关联关系。
在这种实现方式中，NSMF中可以具有网络切片信息和AMF组，也可以仅具有网络切片信息，这样NSMF可以根据已具有的网络切片信息确定实现同一业务的AMF组，从而确定AMF组信息与网络切片信息之间的关联关系。
可选的，在另一种可能的实现方式中，本申请中的步骤S101可以通过以下方式实现：
S1012、NSMF接收网络需求信息，该网络需求信息包括网络切片需求信息或网络切片子网需求信息。
如上所述，该网络请求消息可以为CSMF发送给NSMF的。
S1013、NSMF根据网络需求信息，确定网络切片信息和AMF组信息之间的关联 关系。
具体的，本申请中的步骤S1013可以通过以下方式实现：
S1013a、NSMF根据网络需求信息，获取满足网络需求信息的网络切片信息和AMF组信息。
S1013b、NSMF将满足网络需求信息的网络切片信息和AMF组信息关联，以确定网络切片信息和AMF组信息之间的关联关系。
作为一种实现方式：NSMF中可能存在满足网络需求信息的AMF组信息，可能存在满足网络需求信息的网络切片信息，也可能不存在满足网络需求信息的网络切片信息，因此，步骤S1013a可以通过以下方式实现：
S1013a1、NSMF若确定的至少一个网络切片信息中存在第一网络切片信息，该第一网络切片信息满足网络需求信息，则NSMF将第一网络切片信息与满足网络需求信息的AMF组信息关联，以确定网络切片信息和AMF组信息之间的关联关系。通过将已有的至少一个网络切片信息中的一个网络切片信息与存在的满足网络需求信息的AMF组信息关联，这样可以实现资源的灵活配置。
由于在实际过程中，可能存在两个或两个以上的网络切片信息与一个AMF组信息指示的AMF组承载的业务相同，因此，本申请中的网络切片信息包括两个或两个以上的网络切片信息，例如，可以将一个AMF组信息与用于实现业务A的切片实例关联，以及将AMF组信息与用于实现业务A的切片类型关联。
或者，S1013a2、NSMF若确定的至少一个网络切片信息中不存在满足网络需求信息的网络切片信息，则根据网络需求信息创建满足网络需求信息的网络切片信息，并将新创建的网络切片信息与AMF组选择信息关联，以确定为AMF组信息与网络切片信息之间的关联关系。当已有的网络切片信息中不存在满足网络需求信息的网络切片信息时，通过创建新的网络切片信息，并将新创建的网络切片信息与已有的AMF组关联，这样便可以使得第一管理单元中的每个AMF组均具有与之对应的网络切片信息，从而可以及时(通过NSSMF)为网元配置每个AMF组和各自关联的网络切片信息之间的关联关系，从而使得网元可以根据被配置的关联关系确定出满足UE需求的AMF组信息。
又一种可能的实现方式中，NSMF中的至少一个网络切片信息中存在满足网络需求信息的网络切片信息，但是至少一个接入管理单元组中不存在满足网络需求信息的一个接入管理单元组，因此，步骤S1013a可以通过以下方式实现：
S1013a3、NSMF根据网络需求信息建立满足网络需求信息的AMF组。
S1013a4、NSMF将新建的AMF组信息与至少一个网络切片信息中的一个满足网络需求信息的网络切片信息关联，以确定AMF组信息与网络切片信息中的关联关系。
此外，为了使得NF(例如，网络设备，例如，gNB)明确接入管理单元组和该接入管理单元组包括的一个或多个AMF之间的关系，如图6所示，本申请在步骤S103之后，还包括：
S104、NSMF确定AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中至少一个关联关系。
其中，第一AMF信息为AMF组信息所指示的AMF组包括的所有AMF中的至少 一个AMF的信息，即NSMF可以确定AMF组包括的所有AMF中每个AMF与AMF组之间的关联关系，也可以根据需要确定出所有AMF中满足预设要求(例如，负载满足要求)的一个或多个AMF与AMF组之间的关系。
具体的，NSMF可以将接入管理单元AMF组的标识与第一AMF的标识关联，并将得到的关联关系确定为接入管理单元AMF组第一AMF之间的关联关系，其中，AMF的标识用于识别一个AMF。或者，将接入管理单元AMF组的标识与S-NSSAI关联，并将得到的关联关系确定为接入管理单元组和网络切片选择辅助信息S-NSSAI之间的关联关系。
本发明实施例中的至少一个关联关系可以为AMF组和第一AMF之间的关联关系；也可以为AMF组和网络切片选择辅助信息S-NSSAI之间的关联关系；也可以为AMF组和网络切片选择辅助信息S-NSSAI之间的关联关系和AMF组和第一AMF之间的关联关系。
S105、NSMF向NSSMF发送第二消息，该第二消息包括AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中至少一个关联关系，其中，NSSMF还用于为第二网络单元(例如，网络设备)配置AMF组和第一AMF信息之间的关联关系，和AMF组信息和S-NSSAI之间的关联关系中至少一个关联关系。
S106、NSSMF将AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和S-NSSAI之间的关联关系中至少一个关联关系发送给第二网络单元(网络功能(Network Function，NF)单元)。
作为一种可能的实现方式，NSSMF可以通过配置消息将AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和S-NSSAI之间的关联关系中的至少一个关联关系发送给第二网络单元。
本申请通过步骤S106即可以实现由NSSMF为第二网络单元配置AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和S-NSSAI之间的关联关系中的至少一个关联关系的过程。
可以理解的是，NSSMF可以只为第二网络单元配置AMF组信息和第一AMF信息之间的关联关系，也可以只为第二网络单元配置AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系，或者为第二网络单元既配置AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系，又配置AMF组信息和第一AMF信息之间的关联关系。
可以理解的是，当如图4所示的方法中，第一管理单元为NSMF，第一网络单元为NSSF、NRF以及默认AMF中的至少一项时(即用NSSF、NRF以及默认AMF中的至少一项替代NSSMF时)，步骤S103可以省略。
当如图4所示的方法中第一管理单元为NSMF，第二网络单元为NF(也即用NF替换上述NSSMF)时，步骤S106可以省略。
需要说明的是，本申请中的步骤S101和步骤S104可以是并列的独立步骤，也即NSMF可以仅执行步骤S101到S103，也可以仅执行S104-S106，即NSMF仅确定AMF组信息和网络切片信息之间的关联关系，或者仅确定AMF组信息和第一AMF信息之 间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系。在这种情况下，NSSMF可以仅执行为第一网络单元(例如，网元)配置AMF组信息和网络切片信息之间的关联关系的过程，或者仅执行为第二网络单元(例如，基站)配置AMF组信息和AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系的过程。
当然，本申请中也可以先执行步骤S101到S103再执行步骤S104-S106，即NSMF不仅确定AMF组信息和网络切片信息之间的关联关系，又确定AMF组信息和AMF信息之间的关联关系以及AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系，那么在这种情况下，NSSMF便可以执行为第一网络单元(例如，网元)配置AMF组信息和网络切片信息之间的关联关系的过程，和执行为第二网络单元(例如，基站)配置AMF组信息和第一AMF信息之间的关联关系，和接入管理单元组和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系的过程中任意一个过程。
当然，本申请中也可以先执行步骤S104-S106，再执行步骤S101-S103，即NSMF先确定AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系，再确定AMF组信息和网络切片信息之间的关联关系。本申请仅是以在步骤S103之后还包括S104-S106为例进行说明，在实际过程中S101-S103和S104-S106可以为两个独立的实施过程。
具体的，作为一种可能的实现方式：本申请中的步骤S104可以通过以下方式实现：
S1041、NSMF将AMF组信息与第一AMF消息和网络切片选择辅助信息S-NSSAI中的至少一项关联，以确定AMF组信息和第一AMF信息之间的关联关系和AMF组信息与S-NSSAI之间的关联关系中的至少一个关联关系。
具体的，NSMF将AMF组信息与第一AMF信息关联，以确定AMF组信息和第一AMF信息之间的关联关系，将AMF组信息与网络切片选择辅助信息S-NSSAI关联以确定AMF组信息与S-NSSAI之间的关联关系。
具体的，NSMF将AMF组的标识与第一AMF的标识关联，并将得到的关联关系确定为AMF组信息和第一AMF信息之间的关联关系。NSMF可以将AMF组信息与S-NSSAI关联，并将得到的关联关系确定为AMF组信息和S-NSSAI之间的关联关系。
此外，为了减少NSMF和NSSMF之间的多次交互，本申请步骤S102中的第一消息还可以包括AMF组和第一AMF之间的关联关系以及AMF组和S-NSSAI之间的关联关系中至少一个关联关系。也即NSMF可以直接通过第一消息向NSSMF既发送AMF组和网络切片信息之间的关联关系，又向NSSMF发送AMF组和第一AMF之间的关联关系以及AMF组和S-NSSAI之间的关联关系中至少一个关联关系。在这种情况下，本申请中的步骤S105可以省略。
本申请中NSMF也可以从其他管理单元处获取AMF组信息和网络切片信息之间的关联关系，例如，NSMF可以从其他管理单元发送的第三消息中获取该AMF组信息和网络切片信息之间的关联关系，那么，本申请中第三消息还可以包括AMF组信息和第一AMF信息之间的关联关系以及AMF组信息和S-NSSAI之间的关联关系中至少一个关联关系。因此，在第三消息中包括AMF组信息和第一AMF信息之间的关联关 系以及AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中至少一个关联关系时，NSMF向NSSMF发送的第一消息还可以包括AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和S-NSSAI之间的关联关系中的至少一个关联关系。
本申请提供一种信息配置方法，通过第一管理单元(例如，可以是NSSMF)确定接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和S-NSSAI之间的关联关系中至少一个关联关系，然后通过第一管理单元将该至少一个关联关系发送给第二网络单元(例如，gNB)，由于在实际过程中，第二网络单元并不具有上述至少一个关联关系，因此，通过为第二网络单元配置上述至少一个关联关系，可以使得第二网络单元根据被配置的至少一个关联关系确定满足UE需求的AMF转发UE的业务请求信息。
需要说明的是，在图2所示的架构下，本发明实施例提供的NSMF还可以直接将接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中至少一个关联关系发送给第二网络单元(例如，gNB)。
图7为本申请提供的一种信息配置方法的通信示意图。图7所示的方法可以应用于图3所示的网络架构。如图7所示，本申请提供的一种信息配置方法包括以下步骤：
S201、NSSMF确定第一AMF组信息与第一网络切片信息之间的关联关系，该关联关系用于指示第一网络单元根据第一AMF组信息确定第一网络切片信息，或根据第一网络切片信息确定第一AMF组信息。其中，第一AMF组为至少一个AMF组中的一个AMF组，第一网络切片信息为多个网络切片信息中的至少一个网络切片信息，或者第一网络切片信息为至少一个网络切片信息中的一个网络切片信息。
作为一种可能的实现方式，NSSMF可以将第一AMF组的标识与至少一个网络切片信息中的一个网络切片信息(例如，第一网络切片信息)关联，并将得到的关联关系作为第一接入管理单元AMF组与第一网络切片信息之间的关联关系。
S202、NSSMF向第一网络单元(例如，NRF/NSSF/默认AMF)发送第一消息，该第一消息包括第一AMF组信息与第一网络切片信息之间的关联关系。
其中，第一AMF组信息与第一网络切片信息之间的关联关系用于使得NRF/NSSF/默认AMF根据用户设备的业务请求(例如，注册请求)选择满足要求的接入管理单元AMF组，这是由于NRF/NSSF/默认AMF在接收到UE发送的业务请求时，通常会确定满足该业务请求的网络切片信息，例如，切片实例信息，因此，通过配置第一网络切片信息和第一接入管理单元AMF组之间的关联关系，可以使得NRF/NSSF/默认AMF根据由UE的业务请求消息确定的网络切片信息，确定与该第一网络切片信息存在关联关系的第一接入管理单元AMF组。
本申请提供一种信息配置方法，通过NSSMF确定至少一个AMF组中的一个AMF组信息(例如，第一AMF组信息)和至少一个网络切片信息中的一个网络切片信息(例如，第一网络切片信息)之间的关联关系，即确定第一AMF组信息和第一网络切片信息之间的关联关系，以及将第一AMF组信息与第一网络切片信息之间的关联关系通过第一消息发送给NRF/NSSF/默认AMF，这样在一个网络中包括多个AMF组 时，通过NSSMF确定的关联关系，可以使得最终被配置该关联关系的NRF或NSSF或默认AMF，可以针对相应的UE发起的业务请求选择有效的AMF组，从而使得所选择的AMF组满足UE的业务请求。
可选的，作为另一种可能的实现方式，本申请中的步骤S201可以通过以下方式实现：
S201a、NSSMF接收NSMF发送的第一AMF组与第一网络切片信息之间的关联关系，以确定第一AMF组与第一网络切片信息之间的关联关系。
示例性的，当NSMF与NSSMF交互时，NSMF可以通过在第三消息中携带第一AMF组与第一网络切片信息之间的关联关系，并向NSSMF发送第三消息，因此，NSSMF将从第三消息中得到的第一AMF组与第一网络切片信息之间的关联关系，确定为第一消息中的第一接入管理单元AMF组与第一网络切片信息之间的关联关系。
因此，当步骤S201通过S201a来实现时，如图8所示，在本申请的步骤S201之前，还包括：
S203、NSMF确定至少一个AMF组中的一个AMF组(例如，第一AMF组)与至少一个网络切片信息中的一个网络切片信息(例如，第一网络切片信息)之间的关联关系。
具体的，NSMF可以将第一AMF组的标识与第一网络切片信息之间的关联关系作为第一接入管理单元AMF组与第一网络切片信息之间的关联关系。
S204、NSMF向NSSMF发送第三消息，该第三消息中包括第一AMF组与第一网络切片信息之间的关联关系。
可选的，作为一种可能的实现方式，如图9所示，本申请中的步骤S201可以通过以下方式实现：
S201b、NSSMF将第一AMF组与至少一个网络切片信息中的一个网络切片信息(例如，第一网络切片信息)关联，以确定第一接入管理单元AMF组与第一网络切片信息之间的关联关系。
具体的，本申请中的步骤S201b可以通过以下方式实现：NSSMF根据第一AMF组从至少一个网络切片信息中确定一个网络切片信息，并将确定的一个网络切片信息与第一AMF组关联，以确定第一接入管理单元组和至少一个网络切片信息中的一个网络切片信息之间的关联关系。或，NSSMF根据至少一个网络切片信息中的一个网络切片信息确定第一AMF组信息，并将确定的第一AMF组信息与至少一个网络切片信息中的一个网络切片信息关联，以确定第一AMF组和第一网络切片信息之间的关联关系。
作为又一种可能的实现方式，如图10所示，在本申请提供的步骤S201之前，还包括以下步骤：
S205、NSMF接收业务请求消息，该业务请求消息中携带网络需求信息。
S206、NSMF将该业务请求消息分解为网络切片子网需求信息。
S207、NSMF将网络切片子网需求信息发送给NSSMF。
因此，本申请中的步骤S201可以通过以下方式实现：
S201c、NSSMF接收NSMF发送的子网的需求信息，该子网的需求信息用于指示 NSSMF确定至少一个接入管理单元AMF组中的一个AMF组(例如，第一AMF组)和至少一个网络切片信息中的一个网络切片信息(例如，第一网络切片信息)之间的关联关系。
S201d、NSSMF根据网络切片子网需求信息，确定至少一个接入管理单元AMF组中的一个AMF组(例如，第一AMF组)和至少一个网络切片信息中的一个网络切片信息(例如，第一网络切片信息)之间的关联关系。
具体的，本申请中的步骤S201d可以通过以下方式实现：NSSMF根据子网的需求信息，获取满足子网的需求信息的第一接入管理单元组与第一网络切片信息，并将满足网络切片子网需求信息的第一接入管理单元组与第一网络切片信息与关联，以确定第一接入管理单元组与第一网络切片信息之间的关联关系。
由于在实际过程中，NSSMF中可能仅具有满足网络切片子网需求信息的第一网络切片信息和满足网络切片子网需求信息的第一AMF组中的任意一个或多个，那么，本申请中的步骤S201d具体可以通过以下方式实现：
一方面，NSSMF确定至少一个网络切片信息中存在满足网络切片子网需求信息的一个网络切片信息，则将至少一个网络切片信息中满足网络切片子网需求信息的一个网络切片信息与第一AMF组信息关联，以确定第一AMF组信息与至少一个网络切片信息中的一个网络切片信息(例如，第一网络切片信息)之间的关联关系。
另一方面，NSSMF确定至少一个网络切片信息中不存在满足子网的需求信息的第一网络切片信息，则创建满足子网的需求信息的第一网络切片信息(此时，新创建的网络切片信息可以为一个或多个)，并将新创建的满足子网的需求信息的网络切片信息与第一接入管理单元组(NSSMF中已有的至少一个接入管理单元组中的一个)关联，以确定第一接入管理单元组与第一网络切片信息之间的关联关系。
此外，S201d还可以通过以下方式实现：
一方面，NSSMF确定NSSMF中存在的至少一个接入管理单元组中存在一个满足子网的需求信息的接入管理单元组(即第一接入管理单元组)，则将满足子网的需求信息的第一接入管理单元组与至少一个网络切片信息中的一个网络切片信息关联，以确定第一接入管理单元组与至少一个网络切片信息中的一个网络切片信息之间的关联关系。
另一方面，NSSMF确定NSSMF中存在的至少一个接入管理单元组中不存在满足子网的需求信息的第一接入管理单元组或者NSSMF中不存在满足子网的需求信息的第一接入管理单元组，则创建满足子网的需求信息的第一接入管理单元组，并将新创建的满足子网的需求信息的第一接入管理单元组与至少一个网络切片信息中的一个网络切片信息关联，以确定第一接入管理单元组与至少一个网络切片信息中的一个网络切片信息之间的关联关系。
又或者，NSSMF确定NSSMF中既不存在满足子网的需求信息的第一网络切片信息又不存在满足子网的需求信息的第一接入管理单元组时，则创建满足子网的需求信息的第一网络切片信息与第一接入管理单元组，并将创建的满足子网的需求信息的第一网络切片信息与第一接入管理单元组关联，以确定第一接入管理单元组与第一网络切片信息之间的关联关系。这种情况适用于NSSMF中不存在满足子网的需求信息的 第一网络切片信息和第一接入管理单元组的场景。又或者，在NSSMF中存在满足子网的需求信息的第一网络切片信息与第一接入管理单元组时，NSSMF可以根据子网的需求信息将至少一个网络切片信息中的一个网络切片信息与至少一个接入管理单元组中的一个接入管理单元组关联，以确定第一接入管理单元组与第一网络切片信息之间的关联关系。
可选的，本申请中的网络切片信息包括以下任一项或多项：网络切片实例标识，网络切片实例管理对象标识，网络切片子网实例标识，网络切片子网管理对象标识，网络切片选择辅助信息S-NSSAI，网络切片类型，服务类型，租户的标识以及公用陆地移动通信网PLMN。
可选的，结合图7，如图11所示，本申请提供的方法还包括：
S208、NSSMF确定接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中至少一个关联关系。
作为一种可能的实现方式，NSSMF可以将AMF组的标识和第一AMF的标识之间的关联关系作为AMF组和第一AMF信息之间的关联关系。以及将AMF组的标识和S-NSSAI之间的关联关系作为AMF组和S-NSSAI之间的关联关系。如上所述NSSMF可以确定接入管理单元AMF组信息和第一AMF信息之间的关联关系、也可以确定AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系，也可以确定AMF组信息和第一AMF信息之间的关联关系和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系。
S209、NSSMF向NF(例如，gNB)发送第二消息，该第二消息中包括AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中至少一个关联关系。
本申请提供一种信息配置方法，通过NSSMF确定接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中至少一个关联关系，然后通过NSSMF将该至少一个关联关系发送给NF。由于在实际网络结构中，NF中通常不具有AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中至少一个关联关系，因此，通过NSSMF为NF配置该至少一个关联关系，这样使得NF可以根据被配置的至少一个关联关系确定满足UE需求的AMF转发UE的业务请求信息。
可以理解的是，本申请中NSSMF通过向NF发送第二消息即可以实现通过NSSMF向网元配置接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中至少一个关联关系的过程。
可选的，作为一种可能的实现方式，本申请中的步骤S208可以通过以下方式实现：
S208a、NSSMF将AMF组信息与第一AMF信息和网络切片选择辅助信息S-NSSAI关联，以确定AMF组信息和第一AMF信息之间的关联关系和AMF组与网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系。
可选的，作为另一种可能的实现方式，本申请提供的步骤S208可以通过以下方式实现：
S208b、NSSMF接收NSMF发送的AMF组信息和第一AMF信息之间的关联关系和AMF组信息与网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系，以确定接入管理单元组信息和第一AMF信息之间的关联关系和AMF组信息与网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系。
可以理解的是，NSSMF接收到NSMF发送的AMF组信息和第一AMF信息之间的关联关系，则确定AMF组信息和第一AMF信息之间的关联关系；若接到NSMF发送的AMF组信息与网络切片选择辅助信息S-NSSAI之间的关联关系，则确定AMF组信息与网络切片选择辅助信息S-NSSAI之间的关联关系。
因此，当步骤S208通过S208b来实现时，可选的，结合图8，如图12所示，本申请中的步骤在S208b之前，还包括：
S210、NSMF确定AMF组信息和第一AMF信息之间的关联关系，则确定AMF组和第一AMF信息之间的关联关系中的至少一个关联关系。
具体的，NSMF确定第一AMF的标识与接入管理单元组的标识之间的关联关系，和确定AMF组的标识与网络切片选择辅助信息S-NSSAI之间的关联关系。
S211、NSMF向NSSMF发送第四消息，该第四消息中包括接入管理单元组信息和第一AMF信息之间的关联关系，则确定接入管理单元组信息和第一AMF信息之间的关联关系中的至少一个关联关系。
可选的，作为一种可能的实现方式，本申请中的S208还可以通过以下方式实现：
S208c、NSSMF接收NSMF发送的网络需求消息，该网络需求消息携带网络切片的子网需求信息。可以理解的是，NSMF将自己接收到的请求消息，分解为子网的需求信息并发送给NSSMF。
S208d、NSSMF根据网络切片的子网需求信息，确定接入管理单元组信息和第一AMF信息之间的关联关系，则确定接入管理单元组信息和第一AMF信息之间的关联关系中的至少一个关联关系。
结合图11或图12，如图13所示，本申请在步骤S208之后，还包括：
S212、NSSMF判断第二网络单元是否属于NSSMF的管理范围内，若是，则执行步骤S209，若否，则执行步骤S213。
S213、NSSMF确定第二网络单元不属于NSSMF的管理范围内时，NSSMF向NSMF发送第五消息，第五消息中携带接入管理单元组和第一AMF之间的关联关系，则确定接入管理单元组和第一AMF之间的关联关系中的至少一个关联关系，该第五消息用于指示NSMF确定为第二网络单元配置接入管理单元组和第一AMF之间的关联关系，则确定接入管理单元组和第一AMF之间的关联关系中的至少一个关联关系的目标管理单元。
可选的，该第五消息中还携带第二网络单元的标识，该标识用于唯一识别第二网络单元。
S214、NSMF根据该第五消息，确定目标管理单元。
S215、NSMF向目标管理单元发送配置消息，该配置消息包括接入管理单元组和第一AMF之间的关联关系，则确定接入管理单元组和第一AMF之间的关联关系中的至少一个关联关系，以使得目标管理单元为第二网络单元确定配置接入管理单元组和 第一AMF之间的关联关系，则确定接入管理单元组和第一AMF之间的关联关系中的至少一个关联关系。
S216、目标管理单元为第二网络单元配置接入管理单元组和第一AMF之间的关联关系，则确定接入管理单元组和第一AMF之间的关联关系中的至少一个关联关系。
可选的，本申请中的第三消息还包括：接入管理单元组和第一AMF之间的关联关系，则确定接入管理单元组和第一AMF之间的关联关系中的至少一个关联关系。在这种情况下，上述实施例中的步骤S208可以省略。
可以理解的是，本申请中的步骤S201和S208可以作为两个独立的实施方式，即NSSMF仅确定至少一个AMF组中的一个AMF组(例如，第一AMF组)与至少一个网络切片信息中的一个网络切片信息(例如，第一网络切片信息)之间的关联关系，并只为第一网络单元(NRF或者默认AMF)配置第一AMF组与第一网络切片信息之间的关联关系，也可以仅确定AMF组信息和该AMF组信息所指示的AMF组包括的一个或多个AMF中每个AMF信息之间的关联关系以及AMF组和网络切片选择辅助信息S-NSSAI之间的关联关系中至少一项，并只为gNB配置AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中至少一个关联关系，也可以在一个实施方式中既确定AMF组与多个网络切片信息中至少一个网络切片信息之间的关联关系，又确定AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系。
此外，在如图3所示的架构下，即第一管理单元为NSSMF，第二管理单元为NSMF，第一网络单元为网元的架构下，本申请还提供一种信息配置方法，包括：
S301、NSSMF接收NSMF发送的第一消息，该第一消息包括至少一个接入管理单元AMF组中的一个AMF组的AMF组信息与至少一个网络切片信息中的一个网络切片信息之间的关联关系。
S302、NSSMF向第一网络单元发送至少一个接入管理单元AMF组中的一个AMF组的AMF组信息与至少一个网络切片信息中的一个网络切片信息之间的关联关系。
本申请提供一种信息配置方法，通过NSSMF接收NSMF通过第一消息发送的至少一个AMF组中的一个AMF组和至少一个AMF选择信息中的一个AMF选择信息之间的关联关系，以确定第一AMF组和第一网络切片信息之间的关联关系，这样可以增加NSSMF确定关联关系的便利性，以及减少NSSMF处理器的处理负担，然后将第一AMF组Group与第一网络切片信息之间的关联关系发送给第一网络单元(例如，NRF/NSSF/默认AMF)，这样在一个网络中包括多个AMF组时，通过NSSMF根据NSMF发送的第一消息确定的关联关系，可以使得最终被配置该关联关系的NRF或NSSF或默认AMF，可以针对相应的UE发起的业务请求选择有效的AMF组，从而使得所选择的AMF组满足UE的业务请求。
此外，在如图3所示的架构下，即第一管理单元为NSSMF，第二管理单元为NSMF，第一网络单元为网元的架构下，本申请还提供一种信息配置方法，包括：
S401、NSSMF接收NSMF发送的第一消息，该第一消息包括AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的 关联关系中的至少一个关联关系。
S402、NSSMF将接入管理单元AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系发送给第二网络单元。
本申请提供一种信息配置方法，通过NSSMF接收NSMF通过第一消息发送的AMF组信息和第一AMF信息之间的关联关系，和AMF组信息和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系，这样可以使得NSSMF根据接收到的至少一个关联，将已有的AMF组信息与第一AMF或S-NSSAI相关联，减少NSSMF的处理负担，然后NSSMF将AMF组和第一AMF之间的关联关系，和AMF组和网络切片选择辅助信息S-NSSAI之间的关联关系中的至少一个关联关系发送给第二网络单元(例如，gNB)，由于在实际网络结构中，第二网络单元通常不具备上述至少一个关联关系，因此，现有技术中gNB在UE发起的业务请求时通常会随机的选择一个AMF来转发UE的业务请求，这样可能会使得所选择的AMF并不能满足UE的需求，而本申请通过为第二网络单元配置该至少一个关联关系，可以使得最终被配置该至少一个关联关系的第二网络单元，可以针对相应的UE发起的业务请求选择有效的AMF，以转发UE的业务请求。
上述主要从各个网元之间交互的角度对本申请提供的方案进行了介绍。可以理解的是，各个网元，例如第一管理单元、第二管理单元等为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本发明能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本发明的范围。
本申请可以根据上述方法示例对第一管理单元、第二管理单元等进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。需要说明的是，本申请中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
为了描述方便，本申请在介绍第一管理单元和第二管理单元的结构时，以第一管理单元为NSSMF为例，以第二管理单元为NSMF为例。
在采用集成的单元的情况下，图14示出了上述实施例中所涉及的第二管理单元的一种可能的结构示意图。第二管理单元包括：确定单元101和发送单元102。其中，确定单元101用于支持第二管理单元执行上述实施例中的步骤S101(具体的可以为：S1011、S1011a、S1011b)、S1013、S1013b、S1013a1、S1013a2、S1013a4、S104(具体的可以为S1041)。发送单元102用于支持第二管理单元执行上述实施例中的步骤S102、S105。此外，本申请提供的第二管理单元还包括：接收单元103、获取单元104以及存储单元105。其中，接收单元103用于支持第二管理单元执行上述实施例中的S1012。获取单元104用于支持第二管理单元执行上述实施例中的步骤S1013a以及 S1013a3。存储单元105用于执行第二管理单元保存关联关系的步骤，以及第一管理单元保存关联关系的具体实现过程。和/或用于本文所描述的技术的其它过程。上述方法实施例涉及的各步骤的所有相关内容均可以援引到对应功能模块的功能描述，在此不再赘述。
