Since the core network and the radio access network belong to different operating domains, different OSSs may need to be used to configure the USN in the core network and the RAN nodes in the radio access network respectively.

This method is complex to configure and prone to errors. Moreover, the manual configuration method also requires technicians to plan the configuration content in advance, and then configure based on the planned configuration content.

背景技术
目前，核心网(core network，CN)中存在多个网络功能(network Function，NF)，这些NF均由运营商掌控。其中，部分NF具有以网络为对象进行处理的功能，例如网络级接入、网络级计算或网络级策略等功能；部分NF具有以用户为对象进行处理的功能，例如用户移动管理、用户会话管理、用户策略管理或用户数据转发等功能；部分NF同时具有以网络为对象进行处理的功能和以用户为对象进行处理的功能。
基于处理的对象是网络还是用户，可将执行这些NF的节点划分为实现网络处理功能的节点或实现用户处理功能的节点。其中，实现网络处理功能的节点还可称为网络服务节点(network service node，NSN)，实现用户处理功能的节点还可称为用户服务节点(user service node，USN)。而针对同时具有以网络和用户为对象进行处理的节点，可将其拆分为NSN和USN。例如，接入和移动性管理功能(access and mobility management function，AMF)网元同时具备接入管理(access management，AM)功能(属于网络处理功能)和移动管理(mobility management，MM)功能(属于用户处理功能)，可将AMF网元拆分为实现AM功能的NSN和实现MM功能的USN。
在网络处理功能和用户处理功能分离的场景下，NSN可由运营商控制，USN可由集成商或用户控制。可见，网络处理功能和用户处理功能分离的方式可为集成商或用户提供一定的主权控制能力，能够加强网络对行业的适应性。在网络处理功能和用户处理功能分离的场景下，如何配置USN是一个亟待解决的问题。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例中的技术方案进行清楚、完整的描述。
为了更好的理解本申请实施例公开的通信方法，对本申请实施例适用的通信系统进行描述。
本申请实施例可应用于长期演进(long term evolution，LTE)系统等第四代(4th generation，4G)通信系统、新无线(new radio，NR)系统等第五代(5th generation，5G)通信系统，以及随着通信技术的不断发展，本申请实施例的技术方案还可用于后续演进的通信系统，如第六代(6th-Generation，6G)移动通信技术系统、第七代(7th-Generation，7G)移动通信技术系统等等。
请参阅图1，图1是本申请实施例提供的一种系统架构的示意图，该系统架构包括网络服务节点(network service node，NSN)、用户服务节点(user service node，USN)和无线接入网(radio access network，RAN)节点。图1所示的设备数量和形态用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的NSN、两个或两个以上的USN、 两个或两个以上的RAN节点。图1所示的系统架构以一个NSN、一个USN和一个RAN节点为例进行阐述。
其中，NSN可用于负责网络处理相关功能，例如，NSN可用于负责网络级接入、网络级授权和/或网络级计算等功能。USN可用于负责用户处理相关功能，例如，USN可用于负责用户级移动管理、用户级会话管理、用户级策略处理和/或用户面数据转发处理等功能。RAN节点可用于负责无线接入处理相关功能。另外，NSN、USN和RAN节点中两两之间还可存在用于通信的接口。其中，NSN与USN之间的接口(还可称为NAN-USN接口)可用于负责NSN和USN之间的信令交互，NSN与RAN节点之间的接口(还可称为NAN-RAN接口)可用于负责NSN和RAN之间的信令交互，USN与RAN节点之间的接口(还可称为USN-RAN接口)可用于负责USN和RAN节点之间的信令交互。另外，“NSN”和“USN”是本申请实施例提供的一种示例性的命名方式，其还可以采用其他的命名方式对负责网络处理功能的节点和负责用户处理功能的节点进行命名，不作限制。
以图2所示的5G网络架构为例，NSN可以是5G核心网中具有以网络为对象的处理功能的网元。例如，NSN可以是网络数据分析功能(network data analytics function，NWDAF)网元，NSN还可以是具有接入与移动性管理功能(access and mobility management function，AMF)网元中接入管理(access management，AM)功能的节点。USN可以是5G核心网中具有以用户为对象的处理功能的网元。例如，USN可以是会话管理功能(session management function，SMF)网元、策略控制功能(policy control function，PCF)网元或用户面功能(user plane function，UPF)网元，USN还可以是具有AMF网元中移动管理(mobility management，MM)功能的节点。
本申请实施例中，RAN节点可以是5G网络中的基站或者未来演进的通信系统中的基站、宽带网络业务网关(broadband network gateway，BNG)、汇聚交换机或者非第三代合作伙伴项目(3rd generation partnership project，3GPP)接入设备等。可选的，本申请实施例中的RAN节点可以包括各种形式的基站，例如：宏基站、微基站(也称为小站)、中继站、接入点、5G之后演进的通信系统中实现基站功能的设备、传输接收点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心，以及设备到设备(device-to-device，D2D)、机器到机器(machine-to-machine，M2M)通信中承担基站功能的设备等，本申请实施例对此不作具体限定。
在核心网中的网络处理功能和用户处理功能分离的情况下，网络处理功能可由NSN执行，用户处理功能可由USN执行。其中，NSN可由运营商掌控，USN可由集成商或用户掌控。可见，网络处理功能和用户处理功能分离的方式可以为集成商或用户提供一定的主权控制能力，进而加强网络对行业的适应性。那么，在网络处理功能和用户处理功能分离的场景下，如何对USN和RAN节点进行配置是亟待解决的问题。
一种方式是人为地通过运维系统或网管系统对USN和RAN节点进行配置。下面以人为地通过运营支撑系统(operation support systems，OSS)进行配置的方式为例进行阐述。由于核心网和无线接入网属于不同的运营域，可能需要通过不同的OSS分别为核心网中的USN和无线接入网中的RAN节点进行配置。如果存在多个USN，需要人为地通过核心网对应的OSS为各个USN一一进行配置；如果存在多个RAN节点，需要人为地通过无线接入网对应的OSS为各个RAN节点一一进行配置，这一方式配置复杂，容易出错。并且，人工配置的方式还需要技术人员预先规划配置内容，再基于规划好的配置内容进行配置。在核心网的网 络情况发生变化时，人工配置RAN节点的方式无法实时或准实时地更新RAN节点的配置，也就是说，无线实现实时或准实时的无线接入网和核心网之间的协同闭环。
本申请实施例提供了通信方法100，该方法能够实现在网络处理功能和用户处理功能分离的场景下，NSN直接对USN进行配置，减少了人工配置的复杂度。
本申请实施例提供了通信方法200和通信方法300，这两种方式均能够实现在网络处理功能和用户处理功能分离的场景下，NSN对RAN节点进行配置，进而能够实现实时或准实时的无线接入网和核心网之间的协同闭环，且能够减少人工配置的复杂度。不同之处在于，通信方法200中NSN直接对RAN节点进行配置；通信方法300中NSN通过USN间接对RAN节点进行配置。
下面结合附图对本申请实施例提供的通信方法进行阐述。
请参阅图3，图3是本申请实施例提供的一种通信方法100的流程示意图，该通信方法100从第一网络设备和第二网络设备之间交互的角度进行阐述。其中，第一网络设备是用于控制网络功能的核心网设备，其可以是图1所示的系统架构中的NSN。第二网络设备是用于处理用户面功能和/或控制面功能的核心网设备，其可以是图1所示的系统架构中的USN。
另外，本申请实施例中，用于控制网络功能的核心网设备除了可以是NSN之外，还可以是其他的能够控制网络功能的核心网设备。用于处理用户面功能和/或控制面功能的核心网设备除了可以是USN之外，还可以是其他的能够处理用户面功能和/或控制面功能的核心网设备，不作限制，后文中不再赘述。
该通信方法100包括以下步骤：
S101、第一网络设备向第二网络设备发送第一配置请求消息，该第一配置请求消息用于配置第二网络设备的管控操作。相应的，第二网络设备接收来自第一网络设备的第一配置请求消息。

下面结合图6，以第一网络设备配置第二网络设备和第六网络设备进行流控处理、第一网络设备是具有接入管理功能(access management，AM)的NSN、第二网络设备是具有移动管理(mobility management，MM)功能的USN、第六网络设备是与第二网络设备连接的RAN节点为例进行阐述。这一场景下，NSN可维护RAN节点、NSN和USN的拓扑关系，并且根据拓扑关系中各节点的运行状态决策配置USN和RAN节点的流控启动。
图6中，步骤1-5展示了NSN配置USN进行流控处理的过程。具体地，NSN在决策流控启动的过程中还可确定待配置的USN，再向待配置的USN发起USN管控配置请求。USN可结合USN管控配置请求和其他配置信息(例如，来自RAN节点或网管系统的第一消息)组合决策是否进行流控处理，并向NSN发起USN管控配置应答。如果USN决策进行流控处理，USN可进行流控处理。其中，USN向NSN发起USN管控配置应答和进行流控处理的先后顺序不作限制。另外，NSN向USN发起USN管控配置请求的过程可包括：NSN向USN发送第一配置请求消息，该第一配置请求消息可携带操作类型和USN流控参数，操作类型为USN流控启动。USN向NSN发起USN管控配置应答的过程可包括：USN向NSN发送第一配置应答消息，该第一配置应答消息包括USN决策是否进行流控处理的结果。

步骤11-17展示了NSN通过USN间接配置RAN节点进行流控处理的过程。该方式与NSN直接配置RAN节点进行流控处理的方式之间的不同之处在于，该方式中，RAN管控配置请求和RAN管控配置应答由USN进行转发，待配置的RAN节点可由USN确定。
下面结合图7，以第一网络设备配置第二网络设备对第三网络设备的用户上下文进行备份、第一网络设备配置第六网络设备存储这一备份关系、第一网络设备是具有AM功能的NSN、第二网络设备是具有MM功能的USN#1、第三网络设备是具有MM功能的USN#2、第六网络设备是与USN#1和USN#2连接的RAN节点为例进行阐述。这一场景下，NSN可维护RAN节点、NSN和USN的拓扑关系，并且根据拓扑关系中各节点的运行状态决策配置USN#1和USN#2之间进行备份。另外，在USN#1对USN#2的用户上下文进行备份之后，NSN还将USN#1和USN#2之间的备份关系告知给与USN#1和USN#2连接的RAN节点。
图7中，步骤1-13展示了USN#1对USN#2的用户上下文进行备份的过程。具体地，NSN在决策USN备份的过程中还可确定备份目的为USN#1，备份源为USN#2。NSN可向USN#1发起USN管控配置请求。USN#1可结合USN管控配置请求和其他配置信息(例如，来自RAN节点或网管系统的第一消息)组合决策是否对USN#2的用户上下文进行备份，并向NSN 发起USN管控配置应答。如果USN#1确定对USN#2的用户上下文进行备份，USN#1可准备接受来自USN#2的备份操作请求，NSN可对USN#2发起USN管控配置请求。USN#2可结合USN管控配置请求和其他配置信息组合决策是否允许其用户上下文被USN#1进行备份，并向NSN发起USN管控配置应答。如果USN#2允许其用户上下文被USN#1进行备份，USN#2可向USN#1发起携带了操作类型为用户上下文备份的备份操作请求。USN#1在准备完成后，向USN#2发起备份操作应答。接着，USN#2可向USN#1发送携带了用户上下文的备份执行消息。USN#1保存接收到的用户上下文，并向USN#2发送备份执行应答。其中，步骤11-步骤13可能重复多次直至USN#2对USN#1的用户上下文均进行备份。另外，USN#2在确认备份完成之后，还可将备份完成的消息告知给NSN。
其中，NSN发起USN管控配置请求可包括：NSN发送第一配置请求消息，该第一配置请求消息携带了操作类型、USN#1的标识和USN#2的标识，操作类型为USN备份。USN#1向NSN发起USN管控配置应答可包括：USN#1向NSN发送第一配置请求应答，该第一配置请求应答包括USN#1决策是否对USN#2的用户上下文进行备份的结果。USN#2向NSN发起USN管控配置应答可包括：USN#2向NSN发送第一配置请求应答，该第一配置请求应答包括USN#2决策是否允许其用户上下文被USN#1进行备份的结果。可选的，USN#1的标识和USN#2的标识分别可以是USN#1和USN#2的地址。
步骤14-18展示了NSN直接配置RAN节点对USN#1和USN#2之间的备份关系进行存储的过程。具体地，NSN确定与USN#1和USN#2连接的一个或多个RAN节点，再向确定的每个RAN节点发起RAN管控配置请求。每个RAN节点可结合RAN管控配置请求和其他配置信息(例如，来自USN或网管系统的第二消息)组合决策待存储的USN备份关系，并向NSN发起RAN管控配置应答。每个RAN节点对待存储的USN备份关系进行存储。其中，RAN节点向NSN发起RAN管控配置应答和对待存储的USN备份关系进行存储的先后顺序不作限制。另外，NSN向RAN节点发起RAN管控配置请求的过程可包括：NSN向RAN节点发送第二配置请求消息，该第二配置请求消息可携带操作类型、备份源(即USN#2)的标识和备份目的(即USN#1)的标识，操作类型为RAN备份通知。RAN节点向NSN发起RAN管控配置应答可包括：RAN节点向NSN发送第二配置应答消息，该第二配置应答消息包括RAN节点确定的待存储的USN备份关系。
步骤19-25展示了NSN通过USN#1间接配置RAN节点对USN#1和USN#2之间的备份关系进行存储的过程。该方式与步骤14-18所展示的方式之间的不同之处在于，步骤19-25展示的方式中，RAN管控配置请求和RAN管控配置应答由USN#1进行转发，待配置的RAN节点可由USN#1确定。另外，NSN还可以通过USN#2间接配置RAN节点对USN#1和USN#2之间的备份关系进行存储，不再赘述。
