具体实施方式
下面将结合附图对本申请作进一步地详细描述。方法实施例中的具体操作方法也可以应用于装置实施例或系统实施例中。其中，在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
本申请实施例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实施例的技术方案，并不构成对于本申请实施例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，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
如图1所示，为本申请所适用的一种可能的网络架构示意图。所述网络架构中包括网络存储网元、一个或多个NF网元。可选地，所述网络架构中还包括数据管理网元。可选地，所述网络架构中还包括终端。
终端可以向网络存储网元请求获取某个网络切片中支持某个网络功能的网元的地址信息，然后终端通过该地址信息访问该网元。
终端，是一种具有无线通信功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等；还可以是各种形式的用户设备(user equipment，UE)，移动台(mobile station，MS)，终端设备(terminal device)。
网络存储网元，其具有网络功能的发现能力，本申请中可用于发现网络切片支持的网络功能。网络存储网元可以是第5代(5th generation，5G)网络中的NRF网元。在未来通信如第6代(6th generation，6G)网络中，网络存储单元还可以是其它名称，本申请不做限定。
NF网元，指的是具有某个网络功能的网元。例如NF网元可以是用户面连接功能(User plane Connection Function,UCF)网元、近距离通信服务(Proximity communication Service，ProSe)网元、位置管理功能(Location Management Function，LMF)网元、群组通信服务(Group Communication Service，GCSE)网元、广播多播服务中心(Broadcast Multicast Service Center，BMSC)网元、接入与移动性管理功能(access and mobility management function，AMF)网元、会话管理功能(session management function，SMF)网元等。
数据管理网元，主要用于存储用户数据，如签约信息、鉴权/授权信息。在5G中，数据管理网元可以是统一数据管理(unified data management，UDM)网元，在未来通信如6G中，数据管理网元仍可以是UDM网元，或有其它的名称，本申请不做限定。
可以理解的是，上述功能既可以是硬件设备中的网络元件，也可以是在专用硬件上运行软件功能，或者是平台(例如，云平台)上实例化的虚拟化功能。
为方便说明，本申请后续以网络存储网元为NRF网元，以数据管理网元为UDM网元为例进行说明。为方便说明，进一步地，将NRF网元简称为NRF，将UDM网元简称为UDM。可以理解，后续描述中的NRF可以替换为网络存储网元，UDM可以替换为数据管理网元。这里做统一说明，后续不再赘述。
如图2所示，为本申请提供的一种地址信息的获取方法。图2所示的实施例中以第一终端为例进行说明，该第一终端可以是图1所示的终端。该方法包括以下步骤：
步骤201，第一终端确定需要访问第一网络切片中支持第一NF的类型的网元。
步骤202，第一终端向NRF发送第一NF的类型和第一网络切片的信息，相应地，NRF可以接收到第一NF的类型和第一网络切片的信息。
其中，第一网络切片的信息可以包括网络切片选择辅助信息。例如，网络切片选择辅助信息可以是单网络切片选择辅助信息(single network slice selection assistance information，S-NSSAI)。S-NSSAI用于标识一个网络切片。
其中，第一终端中的第一网络切片的信息可以是通过以下方式获取到的：第一终端中预先配置有该第一终端可以访问的网络切片的标识。另外网络也可以更新第一终端中的该第一终端可以访问的网络切片的信息，比如，AMF网元将更新的配置信息通过与第一终端的控制面连接发送给第一终端，第一终端保存该更新的第一终端可以访问的网络切片的信息。
第一终端向NRF发送第一NF的类型和第一网络切片的信息，是用于请求获取该第一网络切片中支持该第一NF的类型的网元的地址信息。本申请，可以将第一网络切片中支持该第一NF类型的网元称为第一网元。因此也可以理解为，第一终端向NRF发送第一NF的类型和第一网络切片的信息，是用于请求获取第一网元的地址信息。
比如，第一网络切片为网络切片1，第一NF的类型为SMF，即第一终端确定需要访问网络切片1中的SMF网元，则第一终端可以向NRF发送网络切片1的信息和SMF，用于请求获取网络切片1中的SMF网元的地址信息。
需要说明的是，在上述步骤202之前，第一终端可以先建立与NRF之间的连接。
作为一种实现方式，第一终端中可以预先存储有NRF的地址信息，因此第一终端可以通过该NRF的地址信息，建立与NRF之间的连接。
作为又一种实现方式，第一终端还可以向DHCP服务器发送NRF的类型，用于请求获取支持该NRF的类型的网元。然后DHCP服务器根据接收到的NRF的类型，获取支持该NRF的类型的网元的地址信息，即获取到NRF网元的地址信息，然后将获取到的NRF网元的地址信息发送给第一终端。进而，第一终端可以根据接收到的NRF网元的地址信息，建立与NRF网元之间的连接。可以理解，这种情况下NRF可以服务整个PLMN。
作为又一种实现方式，第一终端还可以向DHCP服务器发送NRF的类型和第一网络切片的信息，用于请求获取支持第一网络切片中支持该NRF的类型的网元。然后DHCP服务器根据接收到的第一网络切片的信息和NRF的类型，获取第一网络切片中支持该NRF的类型的网元的地址信息，即获取到NRF网元的地址信息，然后将获取到的NRF网元的地址信息发送给第一终端。进而，第一终端可以根据接收到的NRF网元的地址信息，建立与NRF网元之间的连接。可以理解，这种情况下，NRF可以服务第一网络切片，当然NRF还可以服务其他一个或多个网络切片。
步骤205，NRF判断是否允许第一终端访问第一网络切片中支持第一NF的类型的网元。
NRF接收到第一终端发送的第一NF类型和第一网络切片的信息之后，需要根据第一NF类型和第一网络切片的信息，判断是否允许终端访问第一网络切片中支持第一NF的类型的网元。若允许访问，则执行步骤206-步骤208。若不允许访问，则流程结束，或者是 NRF向第一终端发送失败指示，用于指示获取第一网络切片中支持第一NF的类型的网元的地址信息失败。
作为示例，下面给出NRF判断是否允许第一终端访问第一网络切片中支持第一NF的类型的网元的两种实现方法。
实现方法一，NRF根据预设的策略信息，判断第一终端是否可以访问第一网络切片中支持第一NF的类型的网元。
NRF中存储有网络切片的信息、该网络切片中的NF类型、支持该NF类型的网元的地址信息、支持该NF类型的网元的访问配置信息。该访问配置信息用于指示是否允许终端访问支持该NF类型的网元。下面结合具体示例，以表格的形式为例进行说明。
如表1所示，为NRF中存储的关于网络切片的有关信息。
表1
Figure PCTCN2019090757-appb-000001
基于表1所示的示例，网络切片1的信息包括网络切片1的标识信息且标识信息为S-NSSAI1，网络切片1支持的NF类型包括NF1、NF2和NF3，支持NF1的网元的地址信息为IP1和IP7(例如：支持NF1的网元为多个，该多个网元的地址信息分别为IP1和IP7)，支持NF2的网元的地址信息为IP2，支持NF3的网元的地址信息为IP3，并且，支持NF1的网元和支持NF2的网元允许被终端访问，支持NF3的网元不允许被终端访问，或者可以理解为，网络切片1中的NF1和NF2允许被终端访问，网络切片1中的NF3不允许被终端访问。网络切片2的信息包括网络切片2的标识信息且标识信息为S-NSSAI2，网络切片2支持的NF类型包括NF1、NF2和NF4，支持NF1的网元的地址信息为IP1，支持NF2的网元的地址信息为IP2，支持NF4的网元的地址信息为IP4，并且，支持NF2的网元和支持NF4的网元允许被终端访问，支持NF1的网元不允许被终端访问，或者可以理解为，网络切片2中的NF2和NF4允许被终端访问，网络切片1中的NF1不允许被终端访问。
其中，IP是网络之间互连的协议(Internet Protocol)的缩写。
需要说明的是，表1中的“允许被终端访问”指的是允许被任意一个终端访问，或理解为允许被所有终端访问。表1中的“不允许被终端访问”指的是任意终端都不允许访问，或理解为所有终端都不允许访问。
因此，该实现方式一中，当NRF接收到第一终端发送的第一网络切片的信息和第一NF的类型后，可以先根据预设的策略信息(例如基于表1存储的信息)确定第一网络切片中允许被终端访问的NF的类型。进一步的，若确定第一网络切片中允许被终端访问的NF的类型包括第一NF的类型，则确定允许第一终端访问第一网络切片中支持第一NF的 类型的网元。若确定第一网络切片中允许被终端访问的NF的类型不包括第一NF的类型，则确定不允许第一终端访问第一网络切片中支持第一NF的类型的网元。
下面结合表1进行举例说明。
比如，若第一终端在上述步骤202中发送的第一NF的类型为NF1，第一网络切片的信息为S-NSSAI1。NRF根据表1，可以确定网络切片1中允许被终端访问的NF的类型包括NF1和NF2，由于允许被终端访问的NF的类型包括第一NF的类型(即NF1)，因此NRF可以确定允许第一终端访问网络切片1中的NF1，或者理解为，NRF确定允许第一终端访问网络切片1中支持NF1的网元。
再比如，若第一终端在上述步骤202中发送的第一NF的类型为NF1，第一网络切片的信息为S-NSSAI2。NRF根据表1，可以确定网络切片2中允许被终端访问的NF的类型包括NF2和NF4，由于允许被终端访问的NF的类型不包括第一NF的类型(即NF1)，因此NRF可以确定不允许第一终端访问网络切片2中的NF1，或者理解为，NRF确定不允许第一终端访问网络切片2中支持NF1的网元。
作为又一种实现方式，当NRF接收到第一终端发送的第一网络切片的信息和第一NF的类型后，还可以根据预设的策略信息(例如基于表1存储的信息)，确定第一网络切片中的第一NF是否被允许访问。
比如，若第一终端在上述步骤202中发送的第一NF的类型为NF1，第一网络切片的信息为S-NSSAI1。NRF根据表1，通过S-NSSAI1和NF1可以查找到相应的访问配置信息为“允许被终端访问”，因此可以确定网络切片1中的NF1允许被终端访问。
再比如，若第一终端在上述步骤202中发送的第一NF的类型为NF1，第一网络切片的信息为S-NSSAI2。NRF根据表1，通过S-NSSAI2和NF1可以查找到相应的访问配置信息为“不允许被终端访问”，因此可以确定网络切片1中的NF1不允许被终端访问。
通过上述方法，NRF可以判断是否允许第一终端访问第一网络切片中支持第一NF的网元。
作为一种实现方式，NRF中存储的上述如表1所示的网络切片的相关信息可以是由支持NF的类型的网元主动注册至NRF的。比如，针对第一网络切片中支持第一NF的第一网元，第一网元向NRF发送注册请求消息，注册请求消息包括第一NF的类型，第一网络切片的信息，第一网元的地址信息和第一网元的访问配置信息，该访问配置信息用于指示第一网元是否允许被终端访问。然后NRF存储第一NF的类型，第一网络切片的信息，第一网元的地址信息和第一网元的访问配置信息。实现了将第一网元注册至NRF，以便于后续NRF可以根据本地存储的网络切片的相关信息，判断是否允许终端访问第一网络切片中支持第一NF类型的网元。这里，NRF存储的网络切片的相关信息(例如可以表1所示)，也可以称为预设的策略信息。
实现方法二，包括以下步骤203和步骤204。
具体的，在步骤202之后，步骤205之前，还包括步骤203和步骤204。
步骤203，NRF向UDM发送第一终端的标识和签约数据类型，相应地，UDM可以接收到第一终端的标识和签约数据类型。
NRF发送第一终端的标识和签约数据类型，用于请求获取签约数据类型对应的第一终端的签约数据。UDM接收到第一终端的标识和签约数据类型后，获取签约数据类型对应的第一终端的签约数据，这里的签约数据类型用于指示需要获取的签约数据为第一终端能 够访问的网络切片的信息和网络切片中第一终端能够访问的NF的类型。因此，UDM获取的签约数据包括第一终端能够访问的网络切片的信息和网络切片中第一终端能够访问的NF的类型。
步骤204，UDM向NRF发送第一终端能够访问的网络切片的信息和该网络切片中第一终端能够访问的NF的类型，相应地，NRF可以接收到第一终端能够访问的网络切片的信息和网络切片中第一终端能够访问的NF的类型。
若UDM向NRF发送的第一终端能够访问的网络切片的信息包括第一终端在上述步骤202中发送的第一网络切片的信息，且第一网络切片中第一终端能够访问的NF的类型包括第一终端在上述步骤202中发送的第一NF的类型，则NRF确定允许第一终端访问第一网络切片中支持第一NF的类型的网元。
若UDM向NRF发送的第一终端能够访问的网络切片的信息不包括第一终端在上述步骤202中发送的第一网络切片的信息，或者，若UDM向NRF发送的第一终端能够访问的网络切片的信息包括第一终端在上述步骤202中发送的第一网络切片的信息但第一网络切片中第一终端能够访问的NF的类型不包括第一终端在上述步骤202中发送的第一NF的类型，则NRF确定不允许第一终端访问第一网络切片中支持第一NF的类型的网元。
比如，第一终端在上述步骤202中发送的第一网络切片的信息和第一NF的类型分别是S-NSSAI1(用于标识网络切片1)、NF1。UDM向NRF返回的第一终端能够访问的网络切片的信息和网络切片中第一终端能够访问的NF的类型为：(S-NSSAI1、NF1、NF2、NF3)、(S-NSSAI2(用于标识网络切片2)、NF1、NF4)，即第一终端能够访问的网络切片包括网络切片1和网络切片2，且网络切片1中第一终端能够访问的NF的类型包括NF1、NF2和NF3，网络切片2中第一终端能够访问的NF的类型包括NF1和NF4。由于第一终端能够访问的网络切片的信息包括第一网络切片(即网络切片1)的信息，且第一网络切片中第一终端能够访问的NF的类型包括第一NF的类型(即NF1)，因此，NRF确定允许第一终端访问网络切片1中的NF1。
再比如，第一终端在上述步骤202中发送的第一网络切片的信息和第一NF的类型分别是S-NSSAI1、NF1。UDM向NRF返回的第一终端能够访问的网络切片的信息和网络切片中第一终端能够访问的NF的类型为：(S-NSSAI1、NF2、NF3)、(S-NSSAI2、NF1、NF4)，即第一终端能够访问的网络切片包括网络切片1和网络切片2，且网络切片1中第一终端能够访问的NF的类型包括NF2和NF3，网络切片2中第一终端能够访问的NF的类型包括NF1和NF4。由于第一终端能够访问的网络切片的信息包括第一网络切片(即网络切片1)的信息，但是第一网络切片中第一终端能够访问的NF的类型不包括第一NF的类型(即NF1)，因此，NRF确定不允许第一终端访问网络切片1中的NF1。
再比如，第一终端在上述步骤202中发送的第一网络切片的信息和第一NF的类型分别是S-NSSAI1、NF1。UDM向NRF返回的第一终端能够访问的网络切片的信息和网络切片中第一终端能够访问的NF的类型为：(S-NSSAI3(用于标识网络切片3)、NF2、NF3)、(S-NSSAI2、NF1、NF4)，即第一终端能够访问的网络切片包括网络切片3和网络切片2，且网络切片3中第一终端能够访问的NF的类型包括NF2和NF3，网络切片2中第一终端能够访问的NF的类型包括NF1和NF4。由于第一终端能够访问的网络切片的信息不包括第一网络切片(即网络切片1)的信息，因此，NRF确定不允许第一终端访问网络切片1中的NF1。
因此，通过上述实现方法一或实现方法二，NRF可以确定是否允许第一终端访问第一网络切片中支持第一NF的类型的网元。
需要说明的是，上述步骤203和步骤204为可选步骤。当采用上述实现方法一时则不执行上述步骤203和步骤204，当采用上述实现方法二时则执行上述步骤203和步骤204。
步骤206，NRF获取第一网元的地址信息，第一网元为第一网络切片中支持第一NF的类型的网元。
以表1为例，若第一网元的信息包括S-NSSAI1，第一NF的类型为NF1，则获取的多个第一网元的地址信息分别为IP1和IP7。
步骤207，NRF向第一终端发送第一网元的地址信息，相应地，第一终端可以接收到第一网元的地址信息。
需要说明的是，如果NRF获取到多个第一网元的IP地址，比如获取到IP1和IP7，则NRF可以从中选择一个发送给第一终端，或者将IP1和IP7都发送给第一终端，由第一终端进行进一步的选择。
通过上述方法，实现了向第一终端返回第一终端请求访问的第一网络切片中支持第一NF的类型的网元的地址信息，进而第一终端可以访问该网元。
可选地，还包括以下步骤：
步骤208，第一终端根据第一网元的地址信息向第一网元发起注册流程。
通过发起注册流程，从而第一终端和第一网元可以交互并执行有关的服务。比如当第一网元为LMF网元时，第一终端可以和LMF网元进行第一终端的定位服务操作。
如图3所示，为本申请提供的一种注册方法。该方法包括以下步骤：
步骤301，第一网元向NRF发送注册请求消息，该注册请求消息中包括第一网络切片的信息、第一NF的类型、第一网元的地址信息和第一网元的访问配置信息。相应的，NRF可以接收到该注册请求消息。
该注册请求消息用于请求将第一网元的相关信息注册至NRF，其中，第一网元的相关信息包括第一网络切片的信息、第一NF的类型、第一网元的地址信息和第一网元的访问配置信息。这里，第一网元也可以称为第一网络切片中支持第一NF的类型的网元。第一网络切片的信息包括网络切片选择辅助信息。例如，网络切片选择辅助信息可以是S-NSSAI。S-NSSAI用于标识一个网络切片。第一NF的类型用于指示第一网元的类型。第一网元的地址信息用于指示第一网元的访问地址。第一网元的访问配置信息用于指示第一网元是否允许被终端访问。这里的第一网元也可以称为第一网络切片中支持第一NF的类型的网元。
比如，以第一网元为SMF网元为例，若该SMF网元属于网络切片1，网络切片1的标识信息为S-NSSAI1，SMF网元的地址信息为IP7，网络切片1中的该SMF网元允许被终端访问。则上述步骤301的注册请求消息中包括(S-NSSAI1、SMF、IP7、允许被终端访问)。
步骤302，NRF存储第一网络切片的信息、第一NF的类型、第一网元的地址信息和第一网元的访问配置信息。
例如，NRF将第一网络切片的信息、第一NF的类型、第一网元的地址信息和第一网元的访问配置信息存储至本地的存储单元或存储器中。从而完成对第一网元的相关信息的注册。
可选的，还可以包括以下步骤：
步骤303，NRF向第一网元发送注册响应消息。相应的，第一网元可以接收到该注册响应消息。
当NRF存储第一网络切片的信息、第一NF的类型、第一网元的地址信息和第一网元的访问配置信息成功时，则通过该注册响应消息，通知第一网元注册成功。
当NRF存储第一网络切片的信息、第一NF的类型、第一网元的地址信息和第一网元的访问配置信息失败时，则通过该注册响应消息，通知第一网元注册失败。
通过上述方法，可以实现将第一网元的相关信息注册至NRF，以便于后续可以使用该第一网元的相关信息。
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，上述实现各网元为了实现上述功能，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。

其中，处理单元402可以是处理器或控制器，例如可以是通用中央处理器(central processing unit，CPU)，通用处理器，数字信号处理(digital signal processing，DSP)，专用集成电路(application specific integrated circuits，ASIC)，现场可编程门阵列(field programmable gate array，FPGA)或者其他可编程逻辑器件、晶体管逻辑器件、硬件部件或者其任意组合。其可以实现或执行结合本发明公开内容所描述的各种示例性的逻辑方框，模块和电路。所述处理器也可以是实现计算功能的组合，例如包含一个或多个微处理器组合，DSP和微处理器的组合等等。通信单元403可以是通信接口、收发器或收发电路等。存储单元401可以是存储器。
