技术领域
本申请涉及移动通信技术领域，尤其涉及一种通信方法及装置。
背景技术
第五代通信(the 5th generation，5G)提出一种本地数据网络(local Area Data Network，LADN)。LADN主要为企业、体育场活动、音乐厅等场景而部署的网络。这种LADN网络的特点是，只有当终端位于LADN网络的服务区域(Service Area，SA)时，才能访问该LADN网络。当终端离开LADN的服务区域时，网络断开访问LADN的会话。
当在一个区域部署了新的本地数据网络后，如何通知该网络下的终端更新配置信息，目前还没有解决方案。
发明内容
本申请提供一种通信方法及装置，用以更新终端的配置信息。
第一方面，本申请提供一种通信方法。该方法包括：移动性管理网元根据网络的服务区域和数据网络名称(data network name，DNN)，确定终端列表，该终端列表包括位于服务区域且签约了该DNN的终端的标识，其中，签约了该DNN的终端可以是签约了通配DNN的终端，也可以是未签约通配DNN，但签约了该网络的DNN的终端。接着，移动性管理网元获取该DNN对应的策略信息，以及确定终端列表中的终端分别对应的网络信息，其中，网络信息包括上述DNN和终端的通信区域。然后，移动性管理网元向终端列表中的终端发送策略信息和终端对应的网络信息。
通过上述方法，移动性管理网元首先确定了终端列表，然后将配置信息(包括策略信息和网络信息)发送给终端列表的终端，使得终端根据接收到的配置信息进行更新，实现了更新终端的配置。并且，移动性管理网元只对位于网络的服务区域和签约了网络的DNN的终端进行配置信息的更新，可节约网络开销。
在一种可能的实现方式中，移动性管理网元接收来自通信网元的查询请求，查询请求用于请求获取终端列表，则移动性管理网元向通信网元发送上述终端列表。
进一步地，移动性管理网元还可以接收通信网元的订阅：若有新的终端进入服务区域，且新的终端签约了网络的DNN，则移动性管理网元向通信网元上报新的终端的标识。
通过上述两种方式，移动性管理网元可将位于服务区域且签约了网络的DNN的终端的标识发给给通信网元。其中，通信网元可以是数据管理网元、策略控制网元或网络开放网元等。
在一种可能的实现方式中，移动性管理网元还可以是在接收来自通信网元的通知消息后，执行上述各实施例的通信方法，其中，通知消息包括上述终端列表，通知消息用于通知更新终端列表的终端的配置信息。可选地，通知消息还包括策略信息。
在另一种可能的实现方式中，移动性管理网元接收来自通信网元的通知消息后，执行上述第一方面的通信方法，其中，通知消息包括网络的DNN和/或网络的服务区域，通知消息用于通知更新终端的配置信息。

通过上述方法，通信网元通知移动性管理网元，更新终端列表的终端的配置信息，实现了更新终端的配置。并且，只对位于网络的服务区域和签约了网络的DNN的终端进行配置信息的更新，可节约网络开销。
可选地，通知消息还包括策略信息。
在一种可能的实现方式中，通信网元向移动性管理网元发送查询请求，查询请求用于请求获取终端列表。通信网元接收来自移动性管理网元的终端列表。
在一种可能的实现方式中，通信网元向移动性管理网元订阅：若有新的终端进入服务区域，且新的终端签约了DNN，则移动性管理网元向通信网元上报新的终端的标识。可选地，通信网元将移动性管理网元上报的新的终端的标识加入终端列表。
通过上述两种方式，通信网元可通过移动性管理网元，获取到终端列表，该终端列表的终端，为位于网络的服务区域，且签约了网络的DNN的终端。
第三方面，本申请提供一种通信方法。该方法包括：网络开放网元接收来自应用设备的请求消息，请求消息包括网络的物理覆盖范围；网络开放网元根据网络的物理覆盖范围，确定移动性管理网元和网络的服务区域；网络开放网元向移动性管理网元发送更新消息，更新消息包括网络的数据网络名称DNN和服务区域。
通过上述方法，网络开放网元部署一个具有服务区域的网络，并确定了移动性管理网元，进一步地，还向移动性管理网元发送更新消息，使得移动性管理网元保存网络的DNN和服务区域。从而完成网络部署的同时，还更新了移动性管理网元的配置。
在一种可能的实现方式中，网络开放网元向移动性管理网元发送DNN对应的策略 信息；和/或，网络开放网元向数据管理网元发送DNN对应的策略信息；和/或，网络开放网元向策略控制网元发送DNN对应的策略信息。
在一种可能的实现方式中，网络开放网元还为网络添加指示信息，指示信息用于指示网络为本地数据网络。
第四方面，本申请提供一种通信方法。该方法包括：终端获取策略信息，策略信息包括本地指示和用于标识第一网络的网络标识，本地指示用于指示第一网络为区域限制的网络；所述终端根据策略信息，确定与检测到的应用关联的第一网络是区域限制的网络。
通过上述方法，终端可以获知与应用关联的第一网络是否是区域限制的网络，进而采取针对区域限制的网络的特有的操作。
在一种可能的实现方式中，该方法还包括：终端获取网络信息；当终端位于网络信息指示的区域内时，终端确定发起会话管理流程。例如，终端可从移动性管理网元获取网络信息。在另一种可能的实现方式中，该方法还包括：当终端不具有网络信息时，终端确定不发起会话管理。因此，当终端获取到网络信息时，可进一步根据终端的位置以及网络信息来判断是否发起会话管理流程；当终端没有获取到网络信息时，可认为其位于区域限制的网络的服务区域外，因而不发起会话管理。
在上述描述中，网络信息包括第一网络的网络标识和通信区域信息，通信区域信息用于指示终端的注册区域与第一网络的服务区域的交集区域。
在一种可能的实现方式中，当区域限制的网络为本地数据网络LADN时，网络标识为数据网络名称DNN；或者，当区域限制的网络为本地切片网络时，网络标识为切片标识(例如，S-NSSAI)。
在一种可能的实现方式中，策略信息可以是用户设备路由选择策略URSP。或者，策略信息也可以是其他策略，例如，网络属性策略。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，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，为本申请适用的一种可能的网络架构示意图。该网络架构包括终端和移动性管理网元。可选地，还包括通信网元。
终端是一种具有无线收发功能的设备，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。
移动性管理网元，主要负责移动网络中的移动性管理，如用户位置更新、用户注册网络、用户切换等。例如，移动性管理网元可以是5G中的接入与移动性管理功能(access and mobility management function，AMF)网元。
通信网元，例如可以是数据管理网元、策略控制网元或网络开放网元。
数据管理网元，用于存储用户数据，如签约信息、鉴权/授权信息等。例如，数据管理网元可以是5G中的统一数据管理(Unified Data Management，UDM)网元。
策略控制网元，负责向移动性管理网元提供策略等。例如，策略控制网元可以是5G中的策略控制功能(Policy Control Function，PCF)网元。
网络开放网元，负责将移动网络提供的服务和能力安全地提供给第三方，例如提供给垂直行业用户，边缘计算，应用服务器等。例如，网络开放网元可以是5G中的网络开放功能(network exposure function，NEF)网元。
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，本申请后续以移动性管理网元为AMF网元，数据管理网元为UDM网元，策略控制网元为PCF网元，网络开放网元为NEF网元为例进行说明。并且，为方便说明，后续将AMF网元、UDM网元、PCF网元、NEF网元、分别简称为AMF、UDM、PCF、NEF。
如图2所示，为基于图1所示的系统架构的一种具体系统架构。包括终端、无线接入网络(radio access network)设备、核心网的控制面网元。其中，核心网的控制面网元包括AMF、UDM、PCF和NEF，可选地，还包括应用设备，图2中，以应用设备为5G中的应用功能(application function，AF)设备为例进行说明。
其中，终端、AMF、UDM、NEF、PCF的功能的介绍可参考前述描述，这里不再赘述。
应用设备，负责向第三代合作伙伴计划(3rd Generation Partnership Project， 3GPP)网络提供业务，如影响业务路由、与PCF之间交互以进行策略控制等。本申请后续以应用设备为AF设备为例进行说明。
RAN设备，是一种为终端提供无线通信功能的设备。RAN设备包括基站，具体地，例如包括但不限于：5G中的下一代基站(g nodeB，gNB)、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(例如，home evolved nodeB，或home node B，HNB)、基带单元(BaseBand Unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心等。
下面结合图1-图2，对本申请提供的通信方法做具体说明，以解决背景技术中提到的问题。需要说明的是，本申请并不限定于图1-图2所示的系统架构，还可以应用于未来其它的通信系统，例如6G系统架构等。并且，本申请上述所使用的各个网元的名称，在未来通信系统中，可以保持功能相同，但名称可能会改变。
本申请中，在部署具有覆盖范围的本地数据网络的过程中，可以为本地数据网络分配DNN和服务区域，DNN用于标识该本地数据网络，服务区域用于表示该本地数据网络的覆盖区域。并且，还将DNN和服务区域配置在AMF上。
进一步地，还可以将终端的策略信息配置在PCF、UDM、AMF中的一个或多个网元上。此外，终端的策略信息还可以配置在终端内。其中，终端的策略信息例如可以是应用程序(APP)、DNN、会话与业务的连续性模式(Session and Service Continuity mode，SSC mode)、切片(slice)、local指示中的一个或多个信息之间的对应关系。其中，local指示用于指示网络是否为本地数据网络。
作为示例，策略信息可以是：APP、DNN、SSC mode、slice及local指示之间的对应关系，也可以是：APP、DNN及local指示之间的对应关系，等等。例如，该策略信息可以是UE路由选择策略(UE route selection policy，URSP)。
另外，local指示(也可称为本地数据网络的指示信息)也可包含在策略信息中的DNN信息中。或者，local指示还可以通过除URSP之外的其他策略信息来携带。例如，其他策略信息可以是网络属性策略。网络属性策略中包括用于指示该网络是否为有区域限制的网络的信息。例如，网络属性策略中包含网络标识和local指示之间的对应关系。
Local指示可以通过不同的方式来实现。例如，携带local指示表示网络为本地数据网络，不携带local指示表示网络不是本地数据网络；或者，具有第一值的local指示表示网络为本地数据网络，具有第二值的local指示表示网络不是本地数据网络，本申请在此并不限制。
需要说明的是，上述对于本地数据网络的部署和配置，可以是由网管部署和配置的，也可以是由NEF部署和配置的。本申请后续将会对两种部署和配置方法做具体介绍，这里不再赘述。
需要说明的另一点是，本申请中的本地数据网络可以是LADN，或者，也可以指本地切片网络，如某企业部署的切片网络。本地切片网络允许位于该本地切片的覆盖范围内的用户访问该本地切片网络。例如，本地切片网络允许位于该企业覆盖范围内的 用户访问该本地切片网络。当本地数据网络是LADN时，可通过DNN标识该网络，即，网络标识为DNN。当本地数据网络是本地切片网络时，可通过切片标识，例如，单网络切片选择辅助信息(single network slice selection assistance information，S-NSSAI)，来标识该网络，即，网络标识为切片标识。以下实施例中将以LADN为例进行描述，然而，本申请也可适用于本地切片网络的场景。
在对本地数据网络进行如上所述的部署和配置之后，本申请将可以进一步地对本地数据网络覆盖范围内的终端进行配置更新。
如图3所示，为本申请提供的一种通信方法，该通信方法可用于更新终端的配置信息，包括以下步骤：
步骤300，通信网元向AMF发送通知消息，AMF接收来自通信网元的通知消息。
该通知消息用于通知更新终端的配置信息，具体地，该通知消息用于通知AMF更新该网络覆盖范围下的部分或全部终端的配置信息。配置信息包括终端的策略信息，和/或，网络信息。
需要说明的是，该步骤300为可选的步骤。当执行步骤300时，则是由通信网元触发AMF更新终端的配置信息。其中，通信网元可以是UDM、PCF或NEF。进一步地，在通知消息还可以携带网络的DNN，或者携带网络的服务区域，或者携带DNN和服务区域。
当不执行步骤300时，则直接执行步骤301.即由AMF主动触发更新终端的配置信息。例如可以是AMF定时触发更新终端的配置信息，此时不需要通知网元发送通知消息，即不需要执行步骤300。
步骤301，AMF根据网络的服务区域和DNN，确定终端列表。
网络的服务区域是指本地数据网络的服务区域，例如，LADN的服务区域。
需要说明的是，在网络部署过程中，已经将服务区域和DNN配置在AMF上。
因此该步骤301中，AMF获取网络的服务区域和DNN的方法可以是：
当执行步骤300时，若步骤300的通知消息携带DNN，则AMF可以从通知消息中获取DNN，然后根据DNN，从本地获取到与该DNN对应的服务区域，从而AMF获取到DNN和服务区域。
当执行步骤300时，若步骤300的通知消息携带服务区域，则AMF可以从通知消息中获取服务区域，然后根据服务区域，从本地获取到与该服务区域对应的DNN，从而AMF获取到DNN和服务区域。其中，获取到的DNN可以是一个或多个，本申请对此不做限定。
当执行步骤300时，若步骤300的通知消息携带DNN和服务区域，则AMF可以直接从通知消息中获取到DNN和服务区域。
当不执行步骤300时，则AMF直接从本地获取本地存储的DNN和服务区域。其中，获取到的DNN可以是一个或多个，本申请对此不做限定。
通过上述任一方法，AMF在获取到DNN和服务区域之后，即可确定终端列表，终端列表中包括一个或多个终端的标识。获取终端列表的方法有很多种，作为示例，下面给出三种确定终端列表的方法。
方法一、AMF确定位于网络的服务区域，且签约了通配DNN的终端，并将这些终 端的标识构成的列表，作为终端列表。
其中，终端签约了通配DNN，指的是该终端可应用于所有的DNN，或者理解为，该终端签约了所有的DNN。
例如，AMF确定位于该网络的服务区域的终端包括：终端1、终端2和终端3，其中，终端1和终端2签约了通配DNN，终端3未签约通配DNN，则AMF确定的终端列表为{终端1的标识、终端2的标识}。
方法二、AMF确定位于网络的服务区域，且未签约通配DNN但签约了该网络的DNN的终端，并将这些终端的标识构成的列表，作为终端列表。
例如，上述网络的DNN用DNN0表示。
AMF确定位于该网络的服务区域的终端包括：终端1、终端2和终端3，其中，终端1签约了通配DNN，终端2未签约通配DNN且终端2签约的DNN为DNN1、DNN2，终端3未签约通配DNN且终端3签约的DNN为DNN0、DNN1，则AMF确定的终端列表为{终端3的标识}。
方法三、AMF确定位于网络的服务区域，且签约了通配DNN的终端，以及，确定位于网络的服务区域，且未签约通配DNN但签约了该网络的DNN的终端，并将确定的这些终端的标识构成的列表，作为终端列表。
该方法三是将上述方法一和方法二相结合的一种方法。
例如，上述网络的DNN用DNN0表示。
AMF确定位于该网络的服务区域的终端包括：终端1、终端2和终端3，其中，终端1签约了通配DNN，终端2未签约通配DNN且终端2签约的DNN为DNN1、DNN2，终端3未签约通配DNN且终端3签约的DNN为DNN0、DNN1，则AMF确定的终端列表为{终端1的标识、终端3的标识}。
不管使用上述哪种方法，AMF最终确定的终端列表包括的终端均满足：终端位于服务区域，且终端签约了该网络的DNN。
步骤302，AMF获取DNN对应的策略信息，以及确定终端列表中的终端分别对应的网络信息。
例如，策略信息可以是URSP。
AMF获取策略信息的方式可以是：
方法一、AMF从本地获取策略信息
例如，当策略信息是预配置在AMF上时，则AMF可以从本地获取策略信息。
方法二、AMF从PCF获取策略信息
例如，当策略信息在网络部署过程中配置在PCF上时，则AMF可以从PCF获取策略信息。
再比如，当策略信息在网络部署过程中配置在UDM上，但未配置在PCF上时，若AMF向PCF请求获取策略信息，则PCF可以先从UDM上获取策略信息，然后再发送给AMF。
方法三、AMF从UDM获取策略信息
例如，当策略信息在网络部署过程中配置在UDM上时，则AMF可以从UDM获取策略信息。
再比如，当策略信息在网络部署过程中配置在PCF上，但未配置在UDM上时，若AMF向UDM请求获取策略信息，则UDM可以先从PCF上获取策略信息，然后再发送给AMF。
AMF确定终端列表中的终端分别对应的网络信息的方法，包括：
针对终端列表的每个终端，获取该终端的注册区域，将该终端的注册区域与网络的服务区域的交集确定为该终端的通信区域。然后，将网络的DNN和该终端的通信区域，确定为该终端的网络信息。即，终端的网络信息包括网络的DNN和该终端的通信区域。终端的网络信息也可称为LADN信息。
需要说明的是，当该终端的注册区域与LADN的服务区域没有交集时，终端的通信区域为空。相应的，该终端的网络信息(即，LADN信息)为空。
需要说明的是，终端列表的终端的注册区域可以相同，也可以不同。当终端列表的终端的注册区域都相同时，则终端列表的终端的网络信息都相同。当终端列表的终端的注册区域不尽相同时，则终端列表的终端的网络信息不尽相同。
本申请，可以将策略信息和终端的网络信息，统称为配置信息。即终端的配置信息包括策略信息和网络信息。
步骤303，AMF向终端列表中的终端发送策略信息和终端对应的网络信息。
该步骤303，AMF将确定的终端列表的终端的配置信息(包括策略信息和网络信息)，分别发给每个终端。
当该终端的网络信息(即，LADN信息)为空时，步骤303中，AMF仅向终端列表中的终端发送策略信息。相应的，终端列表中的终端从AMF获取策略信息。可选的，在另一个实施例中，策略信息也可配置在终端中，终端可以通过配置的信息获取策略信息。
通过上述步骤300-步骤303，或通过步骤301-步骤303，AMF首先确定了终端列表，然后将配置信息(包括策略信息和网络信息)发送给终端列表的终端，使得终端根据接收到的配置信息进行更新，实现了更新终端的配置。并且，AMF只对位于网络的服务区域和签约了网络的DNN的终端进行配置信息的更新，可节约网络开销。
如图4所示，为本申请提供的另一种通信方法，该通信方法可用于更新终端的配置信息，包括以下步骤：
步骤401，通信网元向AMF发送查询请求，AMF接收来自通信网元的查询请求。
其中，通信网元可以是UDM、PCF或NEF。查询请求用于请求获取终端列表。
可选地，查询请求包括DNN，和/或，服务区域。
步骤402，AMF根据服务区域和DNN，确定终端列表。
AMF在接收到查询请求后，确定服务区域和DNN。
由于在网络部署过程中，已经将服务区域和DNN配置在AMF上。因此，AMF获取网络的服务区域和DNN的方法可以是：
若查询请求携带DNN，则AMF可以从查询请求中获取DNN，然后根据DNN，从本地获取到与该DNN对应的服务区域，从而AMF获取到DNN和服务区域。
当查询请求携带服务区域，则AMF可以从查询请求中获取服务区域，然后根据服务区域，从本地获取到与该服务区域对应的DNN，从而AMF获取到DNN和服务区域。 其中，获取到的DNN可以是一个或多个，本申请对此不做限定。
当查询请求携带DNN和服务区域，则AMF可以直接从查询请求中获取到DNN和服务区域。
进一步地，AMF在确定了DNN和服务区域之后，确定终端列表。具体方法与上述步骤301中确定终端列表的方法相同，可参考前述描述。
步骤403，AMF向通信网络发送终端列表。
步骤404，通信网元向AMF订阅：若有新的终端进入服务区域，且新的终端签约了网络的DNN，则AMF向通信网元上报新的终端的标识。
其中，AMF确定符合上报条件的新的终端的标识的方法为：若确定有终端位于该服务区域且该终端签约了网络的DNN，并且该终端之前不在该服务区域，则确定该终端为满足上报条件的新的终端。
步骤405，AMF向通信网元上报新的终端的标识。
作为一种实现方式，AMF可以定时上报符合上报条件的一个或多个终端的标识。例如，可以是在上述步骤404中，通信网元在向AMF订阅时，携带一个定时器，该定时器用于通知AMF定时上报的时间间隔。再比如，定时器也可以是预先设置在AMF的，本申请对此不作限定。
作为另一种实现方式，AMF也可以是每次确定了一个符合上报条件的新的终端的标识后，立即向通信网元上报。
另外，需要说明的是，如果一次上报的是多个终端的标识，则可以将这些终端的标识放在一个终端列表中上报至通信网元。
步骤406，通信网元将新的终端的标识加入终端列表。
需要说明的是，作为一种实现方式，上述步骤404-步骤406为可选步骤，即也可以不执行上述步骤404-步骤406。
作为另一种实现方式，还可以将上述步骤404和步骤401融合为一个步骤，即在步骤401发送查询请求的同时，还具有向AMF订阅的功能。
例如，当执行步骤404-步骤406时，下面给出一个具体的示例作为说明，以便于理解该方案。假设通过步骤401-步骤403，通信网元接收到一个终端列表，具体为{终端1的标识、终端2的标识、终端3的标识}。接着，AMF又上报了终端4的标识。则AMF将终端4的标识加入到终端列表，则更新的终端列表为{终端1的标识、终端2的标识、终端3的标识、终端4的标识}。
通过上述步骤401-步骤403，或通过步骤401-步骤406，通信网元可以获取终端列表。
当然，上述只是通信网元获取到终端列表的一种实现方法，在实际应用中，通信网元可以通过其它方法获取到终端列表，本申请对此不做限定。
接着再执行步骤407。
步骤407，通信网元向AMF发送通知消息，AMF接收来自通信网元的通知消息。
通知消息用于通知更新终端列表的终端的配置信息。
该通知消息包括的终端列表，即为通过上述步骤401-步骤403确定的终端列表，或通过步骤401-步骤406确定的终端列表。
通知消息包括终端列表。可选地，通知消息还包括DNN，和/或，服务区域。可选地，通知消息还包括策略信息。
步骤408，AMF获取策略信息和网络信息。
AMF在接收到通知消息后，即确定需要更新终端的配置信息，因此需要确定终端列表中的终端的配置信息。
其中，如果通知消息中包括策略信息，则AMF从通知消息中获取策略信息。如果通知消息不包括策略信息，则AMF可以根据上述步骤302中描述的三种方法中的任一种方法获取到策略信息。
进一步地，AMF获取终端列表中的终端的网络信息的方法，可参考前述上述步骤302中描述的方法，这里不再赘述。
步骤409，AMF向终端列表的终端发送策略信息和网络信息。
步骤409可参考前述上述步骤303中描述的方法，这里不再赘述。
步骤410，AMF向通信网元发送响应消息，通信网元接收来自AMF的响应消息。
响应消息用于通知更新结果。例如更新结果为更新成功，或更新失败等。
需要说明的是，该步骤410为可选的步骤。另外，该步骤410可以发生在步骤407之后的任意一步。
通过上述步骤401-步骤403及步骤407-步骤410，或通过步骤401-步骤410，通信网元首先通过AMF获取到终端列表，然后将终端列表携带于通知消息中发送至AMF，通知AMF对终端列表中的终端进行配置更新，实现了更新终端的配置。并且，AMF只对位于网络的服务区域和签约了网络的DNN的终端进行配置信息的更新，可节约网络开销。
至此，通过图3或图4的方法，位于网络覆盖范围内的终端获取到了网络信息和策略信息。当终端启动某APP(该APP可以访问新部署的网络，如体育场举办方开发的体育赛事直播APP)时，就可以根据策略信息，确定该APP对应的DNN、slice、SSC mode等信息，然后根据local指示确定该APP访问的是有区域限制的网络，则终端再根据网络信息以及终端的位置，判断终端是否位于网络覆盖范围内。当终端在网络覆盖范围内时，终端可以发起会话建立流程或重用现有会话，以进行业务传输。
换句话说，当终端检测到某APP(例如，当用户启动终端上的某APP)时，终端需要确定APP关联的网络标识(例如，DNN或S-NSSAI),以传输该APP对应的业务报文。例如，终端获取到策略信息后，根据策略信息中的local指示获知APP访问的是否为有区域限制的网络。
如上所述，当该终端的注册区域与LADN的服务区域没有交集时，该终端的网络信息为空。因此，终端上可能没有网络信息。
当终端上没有网络信息时，终端认为其位于LADN的服务区域外，因而不发起会话管理。也就是说，当终端上没有网络信息时，终端不发起会话管理。
当终端根据策略信息中的local指示获知APP访问的为有区域限制的网络，且终端上具有网络信息，则终端根据该网络信息和终端的位置，判断终端是否位于LADN的服务区域内。若终端位于LADN的服务区域内，则发起会话管理；若终端不位于LADN的服务区域内，则不发起会话管理。
其中，所述会话管理流程，可以是会话建立流程，或通过会话重用实现业务传输的过程。业务传输过程指的是终端在已有会话上进行该APP的业务报文传输。当重用的会话处于非激活态时，会话管理流程还包括会话的激活流程。
因此，本申请还公开了一种通信方法，如图11所述。该方法包括：
步骤1101，终端获取策略信息，策略信息包括本地指示和用于标识第一网络的网络标识，本地指示用于指示第一网络为区域限制的网络。
步骤1102，所述终端根据策略信息，确定与检测到的应用关联的第一网络是区域限制的网络。
通过上述方法，终端可以获知与应用关联的第一网络是否是区域限制的网络，进而采取针对区域限制的网络的特有的操作。
在一种可能的实现方式中，该方法还包括：终端获取网络信息；当终端位于网络信息指示的区域内时，终端确定发起会话管理流程。例如，终端可从移动性管理网元获取网络信息。在另一种可能的实现方式中，该方法还包括：当终端不具有网络信息时，终端确定不发起会话管理。因此，当终端获取到网络信息时，可进一步根据终端的位置以及网络信息来判断是否发起会话管理流程；当终端没有获取到网络信息时，可认为其位于区域限制的网络的服务区域外，因而不发起会话管理。
在上述描述中，网络信息包括第一网络的网络标识和通信区域信息，通信区域信息用于指示终端的注册区域与第一网络的服务区域的交集区域。
在一种可能的实现方式中，当区域限制的网络为LADN时，网络标识为DNN；或者，当区域限制的网络为本地切片网络时，网络标识为切片标识(例如，S-NSSAI)。
在一种可能的实现方式中，策略信息可以是URSP。或者，策略信息也可以是其他策略，例如，上述网络属性策略。
进一步地，当终端离开网络覆盖范围时，对保存的网络信息以及策略信息，可以采取如下处理方式：
处理方式一、当终端判断自己不在服务区域内时，终端删除网络信息和策略信息。
处理方式二、当终端判断自己不在服务区域内时，终端启动定时器。当定时器超时时，终端删除网络信息和策略信息。其中，定时器可以是终端自己配置的，也可以是通过步骤303或步骤409发送给终端的。
综上，通过图3或图4所示的方法，可以更新位于新部署的网络的覆盖范围内的终端的配置信息。
下面进一步介绍本申请提供的针对新的网络的部署方法，该部署方法是在图3和图4所示的方法实施例之前执行。
如图5所示，为本申请提供的一种通信方法，或称为网络部署方法，包括以下步骤：

其中，目标AMF的标识指的是网络覆盖范围内的AMF的标识信息。其中，标识信息例如可以是地址信息。
需要说明的是，在执行步骤501之前，即部署新的网络之前，存在已经注册至3GPP网络的终端，则这些终端在注册的过程中，将由AMF保存终端的签约数据。例如，签约数据包括终端签约的DNN。签约的DNN可以是通配DNN，也可以是签约了某些具体的DNN。
通过上述步骤501-步骤503，由网管系统对新的网络进行部署，具体地，分别对AMF、PCF及UDM进行配置。

可选地，请求消息还包括网络入口点和网络需求。其中，网络入口点(data network access identifier，DNAI)是部署应用程序时访问一个或多个DN的用户面的标识。。网络需求例如包括服务质量(Quality of Service，QoS)、APP列表等。
步骤602，NEF根据网络的物理覆盖范围，确定AMF和网络的服务区域；
NEF将网络的物理覆盖范围映射成核心网可以识别的范围，例如映射为服务区域。进一步地，还可以为该网络生成DNN。
NEF根据网络的物理覆盖范围，确定AMF。确定的AMF为服务区域内的AMF。
进一步地，若请求消息包括网络入口点和网络需求，则还可以根据网络的物理覆盖范围，网络入口点和网络需求，判断网络中是否存在合适的网元(如用户面功能(User Plane Function，UPF)网元、AMF、会话管理功能(Session Management Function，SMF)网元等)为该网络提供服务。若不存在，则NEF与管理和编排器(Management and Orchestration，MANO)交互，以使MANO在相应的位置部署网元实例。
进一步地，作为一种示例，还可以通过下述步骤603-步骤605的方式，对各网元进行配置，且步骤603、步骤604、步骤605之间没有明确的先后执行顺序。
步骤603、NEF向UDM发送DNN、服务区域及AMF的标识。
可选地，还向UDM发送策略信息。
步骤604、NEF向PCF发送策略信息。
步骤605，NEF向AMF发送DNN和服务区域。
可选地，还向AMF发送策略信息。
通过上述步骤603-步骤605，对各网元进行配置。从而实现了由NEF对网络进行配置。作为一种实现方式，还可以由NEF为网络添加指示信息，指示信息用于指示网 络为本地数据网络。例如添加的指示信息为:local指示，用于指示该网络为本地数据网络。
进一步地，在完成了上述网络配置之后，还可以执行步骤606。
步骤606，NEF向AMF发送更新消息，更新消息包括网络的数据网络名称DNN和服务区域。
该步骤606用于触发AMF更新终端的配置信息。该步骤606即可以是图3所示的实施例中的步骤300。
需要说明的是，在执行步骤601之前，即部署新的网络之前，存在已经注册至3GPP网络的终端，则这些终端在注册的过程中，将由AMF保存终端的签约数据。例如，签约数据包括终端签约的DNN。签约的DNN可以是通配DNN，也可以是签约了某些具体的DNN。
