具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。

为便于理解本申请实施例，首先结合图1简单介绍本申请实施例适用的5G***。
应理解，本文中描述的5G***仅是示例，不应对本申请构成任何限定，本申请提供的通信方法还可以适用于其他的***，本申请对于应用场景不进行赘述。
还应理解，5G***中某些网元之间可以采用服务化接口，或点对点的接口进行通信，下面结合图1介绍基于点对点接口的5G***框架，基于服务化接口的5G***框架可以参考目前相关技术中的介绍，本申请不进行说明。
作为示例性说明，图1示出了本申请实施例适用的5G***的架构示意图。图1为基于点对点接口的5G网络架构示意图。如图1所示，该网络架构可以包括但不限于以下网元(或者称为功能网元、功能实体、节点、设备等)：
用户设备(user equipment，UE)、(无线)接入网设备(radio access network，(R)AN)、接入和移动性管理功能(access and mobility management function，AMF)网元、会话管理功能(session management function，SMF)网元、用户面功能(user plane function，UPF)网元、策略控制功能(policy control function，PCF)网元、统一数据管理(unified data management，UDM)网元、数据网络(data network，DN)、统一数据管理(unified data management，UDM)、统一数据存储(unified data repository，UDR)以及个人物联网络功能实体(personal IoT network function，PIN function)等。

此外，终端设备还可以是物联网(Internet of things，IoT)***中的终端设备。IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。IoT技术可以通过例如窄带(narrow band， NB)技术，做到海量连接，深度覆盖，终端省电。
应理解，终端设备可以是任何可以接入网络的设备。终端设备与接入网设备之间可以采用某种空口技术相互通信。
可选地，用户设备可以用于充当基站。例如，用户设备可以充当调度实体，其在V2X或D2D等中的用户设备之间提供侧行链路信号。比如，蜂窝电话和汽车利用侧行链路信号彼此通信。蜂窝电话和智能家居设备之间通信，而无需通过基站中继通信信号。
2、(R)AN：用于为特定区域的授权用户设备提供入网功能，并能够根据用户设备的级别，业务的需求等使用不同服务质量的传输隧道。
(R)AN能够管理无线资源，为用户设备提供接入服务，进而完成控制信号和用户设备数据在用户设备和核心网之间的转发，(R)AN也可以理解为传统网络中的基站。
示例性地，本申请实施例中的接入网设备可以是用于与用户设备通信的任意一种具有无线收发功能的通信设备。该接入网设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(home evolved Node B，HeNB，或home Node B，HNB)、基带单元(baseBand unit，BBU)，无线保真(wireless fidelity，WIFI)***中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G，如，NR，***中的gNB，或，传输点(TRP或TP)，5G***中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，接入网设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的接入网设备，也可以将CU划分为核心网(core network，CN)中的接入网设备，本申请对此不做限定。
3、UPF网元：主要包括以下功能：数据包路由和传输、包检测、业务用量上报、服务质量(quality of service，QoS)处理、合法监听、上行包检测、下行数据包存储等用户面相关的功能。
在5G通信***中，用户面网元可以是UPF网元。在未来通信***中，用户面网元仍可以是UPF网元，或者，还可以有其它的名称，本申请不做限定。

在5G通信***中，数据网络可以是DN。在未来通信***中，数据网络仍可以是DN，或者，还可以有其它的名称，本申请不做限定。
5、AMF网元：主要包括以下功能：连接管理、移动性管理、注册管理、接入认证和授权、可达性管理、安全上下文管理等接入和移动性相关的功能。

6、SM F网元：主要用于会话管理、终端设备的网络互连协议(internet protocol，IP)地址分配和管理、选择可管理用户平面功能、策略控制和收费功能接口的终结点以及下行数据通知在5G通信***中，会话管理网元可以是SMF网元。
在未来通信***中，会话管理网元仍可以是SMF网元，或者，还可以有其它的名称，本申请不做限定。
7、PCF网元：用于指导网络行为的统一策略框架，为控制面功能网元(例如AMF，SMF网元等)提供策略规则信息等。
在5G通信***中，该策略控制网元可以是PCF网元。在未来通信***中，策略控制网元仍可以是PCF网元，或者，还可以有其它的名称，本申请不做限定。
8、UDM：可以理解为统一数据管理网元在5G架构中的命名。其中，统一数据管理网元主要包括以下功能：统一数据管理，支持3GPP认证和密钥协商机制中的认证信任状处理，用户身份处理，接入授权，注册和移动性管理，签约管理，短消息管理等。
9、UDR：主要用于签约数据、策略数据、应用数据等类型数据的存取功能。
可以理解的是，上述网元或者功能网元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。
10、PIN function：用于执行PIN的创建与管理，包括：PIN的创建、更新、删除；管理PIN的标识、PIN设备的标识、PIN设备在PIN中的角色、用于PIN设备间通信的IP地址；管理PIN设备建立协议数据单元(protocol data unit，PDU)会话的切片、数据网络名称(data network name，DNN)等参数。
应理解，本申请实施例中涉及的PIN function为一个逻辑功能实体，在实际部署时可以与其他网元合设，例如与AMF合设，或者与PCF合设。合设后，PIN function与合设的网元支之间的交互为内部交互。
从图1可以看出，图1中的各个控制面网元之间的接口是点对点的接口。
在图1所示的架构中，各个网元之间的接口名称及功能如下：
1)N1：AMF与终端之间的接口，可以用于向终端传递QoS控制规则等。
2)N2：AMF与RAN之间的接口，可以用于传递核心网侧至RAN的无线承载控制信息等。
3)N3：RAN与UPF之间的接口，主要用于传递RAN与UPF间的上下行用户面数据。
4)N4：SMF与UPF之间的接口，可以用于控制面与用户面之间传递信息，包括控制面向用户面的转发规则、QoS控制规则、流量统计规则等的下发以及用户面的信息上报。
5)N5：AF与PCF之间的接口，可以用于应用业务请求下发以及网络事件上报。
6)N6：UPF与DN的接口，用于传递UPF与DN之间的上下行用户数据流。
7)N7：PCF与SMF之间的接口，可以用于下发PDU会话粒度以及业务数据流粒度控制策略。
8)N8：AMF与UDM间的接口，可以用于AMF向UDM获取接入与移动性管理相关签约数据与鉴权数据，以及AMF向UDM注册终端当前移动性管理相关信息等。
9)N9：UPF和UPF之间的用户面接口，用于传递UPF间的上下行用户数据流。
10)N10：SMF与UDM间的接口，可以用于SMF向UDM获取会话管理相关签约数据，以及SMF向UDM注册终端当前会话相关信息等。
11)N11：SMF与AMF之间的接口，可以用于传递RAN和UPF之间的PDU会话隧道信息、传递发送给终端的控制消息、传递发送给RAN的无线资源控制信息等。
12)PIN function与UDM或AMF之间的接口可以称为Nx。
需要说明的是，作为一种可能的实现方式，PIN function可以与其他网元合设，为了便于描述，该与PIN function合设的网元称为被合设的网元。在合设的情况下，PIN function和被合设的网元之间的交互通过内部交互实现，与其他的网元之间的交互可以通过被合设的网元进行；作为另一种可能的实现方式，PIN function可以单独设立，在单独设立的情况下，PIN function和其他的网元之间的交互可以通过接口进行，接口名称本申请不做限定。
另外，需要说明的是，图1中的各个控制面网元之间的接口还可以是服务化接口，本申请不再赘述。
可以理解的是，上述网元或者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，以接入管理功能网元为AMF网元，会话管理网元为SMF网元为例进行说明。进一步地，将AMF网元简称为AMF，SMF网元简称为SMF。即本申请后续所描述的AMF均可替换为接入管理功能网元，SMF均可替换为会话管理网元。
为方便说明，本申请后续，以装置为AMF实体、SMF实体为例，对通信的方法进行说明，对于装置为AMF实体内的芯片、SMF实体内的芯片的实现方法，可参考装置分别为AMF实体、SMF实体的具体说明，不再重复介绍。
需要说明的是，图1中所涉及的各个网元以及网元之间的通信接口的名称是以目前协议中规定的为例进行简单说明的，但并不限定本申请实施例只能够应用于目前已知的通信***。因此，以目前协议为例描述时出现的标准名称，都是功能性描述，本申请对于网元、接口或信令等的具体名称并不限定，仅表示网元、接口或者信令的功能，可以对应的扩展到其它***，比如4G或未来通信***中。
另外，还需要说明的是，在某些网络架构中，AMF网元、SMF网元、PCF网元以及UDM网元等网络功能网元实体都称为网络功能网元(network function，NF)网元；或者，在另一些网络架构中，AMF网元，SMF网元，PCF网元，UDM网元等网元的集合都可以称为控制面功能网元。
图1为本申请实施例适用的通信***，为了便于理解本申请实施例的技术方案，在以5G架构为基础介绍本申请实施例的方案之前，首先对本申请实施例可能涉及到的5G中的一些术语或概念进行简单描述。
1、个人物联网络(personal IoT network，PIN)。
个人物联网络是以个人(或者说个体)用户为中心，通过用户的终端设备(如，手机)，按照约定协议，连接智能设备与其它信息资源，满足用户高品质、便捷化生活需求的智能服务***。
物联网按需求侧与供给侧分为消费物联网与产业物联网，其中个人物联网络与家用物联网络是消费物联网的子分类，二者的关系取决于物联网终端用户的角色与场景性质。提及个人物联网时更强调以个人为中心的移动场景，提及家用物联网时更强调以家庭用户为中心的弱移动性的家庭空间场景。个人物联网是物联网中关键的移动连接点，将家用物联网与产业物联网串联，是万物互联的关键基础。
2、个人设备间通信。
近些年来，随着通信技术的发展，用户同时拥有的电子设备的数量越来越多，例如，用户有手机、pad、电脑、手表等具有通信能力的电子设备以及越来越多的可以联网的智能家用设备(如，智能门锁、智能摄像头、智慧显示屏、智能打印机)，因此个人设备间的通信(如，通过手机远程控制家用设备，从而获取设备提供的服务，如图2所示)成为了新的通信需求。
为了便于理解，结合图2简单介绍个人设备间通信，图2是一种设备间通信的方法的示意图，具体流程包括：UE通过5G核心网以及智能设备网关控制智能设备，其中，UE可以理解为用户手持设备(如，手机)，智能设备可以理解为家用设备(如，智能门锁、智能摄像头等)。
3、PIN元(PIN element)。
本申请中智能设备也可以称为PIN element，即智能设备可以理解为个人物联网络中的元素。
由上述可知，随着通信技术的发展，个人设备间通信的优化成为亟待解决的问题。目前，个人设备间通信(如，UE控制智能设备)主要包括：
智能设备提供商通常会发布一款手机应用(application，APP)，用于管理智能设备，另外会有一个服务器，UE控制智能设备的流程，通常是由UE将控制指令发送到设备厂商服务器，再由设备厂商服务器将控制指令发送到目标智能设备，从而实现手机对智能设备的控制。如图3所示，图3是一种UE控制智能设备的示意性流程图。包括以下步骤：
S310，智能设备注册到智能设备厂商服务器。
S320，UE中安装该智能设备厂商发布的APP，该APP用于管理该智能设备。
在UE需要向智能设备发送控制指令的情况下，图3所示的流程还包括：
S330，UE中安装的APP将控制指令发送给智能设备厂商服务器。
S340，智能设备厂商服务器将控制指令发送给智能设备。
S350，智能设备向智能设备厂商服务器发送响应于上述的控制指令的响应。
S360，智能设备厂商服务器向UE发送响应于上述的控制指令的响应。
基于上述流程完成对智能设备的控制。
从图3所示的流程中可以看出，UE与智能设备之间的交互依赖于智能设备厂商服务器，如果用户的不同智能设备属于不同的智能设备厂商服务器，则需要分别安装各智能设备厂商服务器提供的APP，因此图3所示的方法对于不同智能设备厂商服务器的智能设备无法做到统一管理。
另外，智能设备厂商服务器对请求控制智能设备的UE无需鉴权认证，存在对智能设备操控或者获取服务的安全性问题。
为了避免发生上述UE控制智能设备的方法存在的缺点，本申请提供一种通信方法，能够优化个人设备间通信流程。
下文示出的实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或核心网设备，或者，是终端设备或核心网设备中能够调用程序并执行程序的功能模块。
为了便于理解本申请实施例，做出以下几点说明。
第一，在本申请中，“用于指示”可以理解为“使能”，“使能”可以包括直接使能和间接使能。当描述某一信息用于使能A时，可以包括该信息直接使能A或间接使能A，而并不代表该信息中一定携带有A。
将信息所使能的信息称为待使能信息，则具体实现过程中，对待使能信息进行使能的方式有很多种，例如但不限于，可以直接使能待使能信息，如待使能信息本身或者该待使能信息的索引等。也可以通过使能其他信息来间接使能待使能信息，其中该其他信息与待使能信息之间存在关联关系。还可以仅仅使能待使能信息的一部分，而待使能信息的其他部分则是已知的或者提前约定的。例如，还可以借助预先约定(例如协议规定)的各个信息的排列顺序来实现对特定信息的使能，从而在一定程度上降低使能开销。同时，还可以识别各个信息的通用部分并统一使能，以降低单独使能同样的信息而带来的使能开销。
第二，在本申请中示出的第一、第二以及各种数字编号(例如，“#1”、“#2”等)仅为描述方便，用于区分的对象，并不用来限制本申请实施例的范围。例如，区分不同消息等。而不是用于描述特定的顺序或先后次序。应该理解这样描述的对象在适当情况下可以互换，以便能够描述本申请的实施例以外的方案。
第三，在本申请中，“预设”可包括预先定义，例如，协议定义。其中，“预先定义”可以通过在设备(例如，包括用户设备或核心网设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现，本申请对于其具体的实现方式不做限定。
第四，本申请实施例中涉及的“保存”，可以是指的保存在一个或者多个存储器中。所述一个或者多个存储器，可以是单独的设置，也可以是集成在编码器或者译码器，处理器、或通信装置中。所述一个或者多个存储器，也可以是一部分单独设置，一部分集成在译码器、处理器、或通信装置中。存储器的类型可以是任意形式的存储介质，本申请并不对此限定。
第五，本申请实施例中涉及的“协议”可以是指通信领域的标准协议，例如可以包括5G协议、新空口(new radio，NR)协议以及应用于未来的通信***中的相关协议，本申请对此不做限定。
以下，不失一般性，以网元之间的交互为例详细说明本申请实施例提供的通信的方法。
为了便于理解，下文中以第一网络设备为AMF、第二网络设备为SMF、第三网络设备为PCF、第四网络设备为PIN function、第五网络设备为UPF、第六网络设备为UDM、第七网络设备为UDR为例进行说明。
需要说明的是，本申请中对于网络设备的名称不做任何的限定。
例如，第一网络设备可以是接入和移动性管理功能网元。接入和移动性管理功能网元可以是AMF，或者能够实现接入和移动性管理功能的其他网元。
