在又一种可能的实现方式中，移动性管理网元还可以向其他移动性管理网元发送第五指示信息，该第五指示信息用于通知该其他移动性管理网元：终端的配置的更新暂未完成，该其他移动性管理网元为切换后为终端提供服务的移动性管理网元。基于该方案，若发生移动性管理网元的切换，由移动性管理网元切换为其他移动性管理网元，则移动性管理网元可以通知该其他移动性管理网元：终端的配置的更新暂未完成，从而后续等到目标业务执行完毕后，可由该其他移动性管理网元再继续执行更新终端的配置，从而有助于在终端的配置更新流程中保障目标业务的连续性。
在又一种可能的实现方式中，该第五指示信息还用于指示该其他移动性管理网元向会话管理网元发送第四订阅请求，所述第四订阅请求用于请求当目标业务结束时通知该其他移动性管理网元。或者说，移动性管理网元还可以向其他移动性管理网元发送第五指示信息，以使其他移动性管理网元向会话管理网元发送第四订阅请求。
在又一种可能的实现方式中，移动性管理网元还可以向上述其他移动性管理网元发送第六指示信息，该第六指示信息用于指示该其他移动性管理网元向会话管理网元发送第四订阅请求，所述第四订阅请求用于请求当目标业务结束时通知该其他移动性管理网 元。或者说，移动性管理网元还可以向上述其他移动性管理网元发送第六指示信息，以使其他移动性管理网元向会话管理网元发送第四订阅请求。基于该方案，可以由切换后的其他移动性管理网元向会话管理网元订阅目标业务的结束通知，从而当会话管理网元确定目标业务结束后可以直接通知该其他移动性管理网元。第三方面，本申请提供一种装置，该装置可以是移动性管理网元，也可以是芯片或电路。该装置具有实现上述第一方面的各实施例的功能。该功能可以通过硬件实现，也可以通过硬件执行相应的软件实现。该硬件或软件包括一个或多个与上述功能相对应的模块。

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，为本申请所适用的一种可能的系统架构。所述系统架构包括移动性管理网元，可选地还可以包括会话管理网元，进一步地还可以包括终端。
终端通过接入网(如通过无线接入网络(radio access network，RAN)设备)接入到核心网。核心网包括控制面网元和用户面网元，其中，控制面网元例如包括移动性管理网元，进一步地，还可以包括会话管理网元等。
移动性管理网元，主要用于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。在5G中，移动性管理网元可以是接入与移动管理功能(access and mobility management function，AMF)网元，在未来通信如第六代(6th generation，6G)中，移动性管理网元仍可以是AMF网元，或者有其它名称，本申请对此不作限定。
会话管理网元，主要用于移动网络中的会话管理，如会话建立、修改、释放。具体功能如为用户分配互联网协议(internet protocol，IP)地址、选择提供报文转发功能的用户面功能网元等。在5G中，会话管理网元可以是会话管理功能(session management function，SMF)网元，在未来通信如6G中，会话管理网元仍可以是SMF网元，或有其它的名称，本申请不做限定。
终端可以与上述网络架构中的移动性管理网元通过非接入层(non access stratum，NAS)消息通信，在一种实现方式中，终端可以通过RAN设备转发NAS消息到移动性管理网元，以及通过RAN设备接收来自移动性管理网元的NAS消息。
本申请实施例中，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)。
RAN设备，也称为基站，是一种为终端提供无线通信功能的设备，包括但不限于：5G中的下一代基站(next generation node B,gNB)、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。本申请中的基站还可以是未来可能出现的其他通信系统中为终端提供无线通信功能的设备。
可以理解的是，上述各个网元的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，本申请后续以会话管理网元为SMF网元，移动性管理网元为AMF网元为例进行说明。并且，为方便说明，进一步地，将SMF网元、AMF网元，分别简称为SMF、AMF。
下面结合图1所示的网络架构，介绍本申请提供的更新配置的方法，该方法可用于解决背景技术中存在的问题。
如图2所示，为本申请提供的一种更新配置的方法，该方法中的AMF可以是图1所示的移动性管理网元，该方法中的SMF可以是图1所示的会话管理网元，该方法中的终端可以是图1所示的终端。该方法包括以下步骤：
步骤201，AMF确定需要更新终端的配置。
AMF确定需要更新终端的配置的方法，例如可以是AMF需要改变终端配置中终端接入和移动性管理相关参数，比如统一数据管理(unified data management，UDM)网元通知AMF终端的签约信息需要更新，或者可以是网络切片配置改变等。
步骤202，AMF判断终端当前是否存在目标业务。
当AMF确定需要更新终端的配置时，则进一步判断终端当前是否存在目标业务。其中，该目标业务可以是需要保障业务连续性的业务，即不能中断的业务，比如可以是紧急业务，高优先级业务，或不能中断的基于IMS的业务等。终端存在目标业务指的是有目标业务的数据流，或为目标业务创建了协议数据单元(protocol data unit，PDU)会话等。
步骤203，AMF若确定终端当前存在目标业务，则暂停执行更新终端的配置。
其中，AMF暂停执行更新终端的配置，例如可以是，AMF不向终端发送用于触发或指示终端更新配置的配置更新消息，从而终端接收不到配置更新消息，就不会触发配置更新流程。
上述实施例，AMF在确定需要更新终端的配置时，首先判断终端当前是否存在目标业务，若确定存在目标业务，则暂停执行更新终端的配置，有助于避免中断目标业务的执行。AMF可等到目标业务执行完毕后再继续执行更新终端的配置，从而有助于在终端的配置更新流程中保障目标业务的连续性。
上述步骤202之后，AMF若确定终端当前不存在目标业务，则可以按照现有技术的方法，向终端发送配置更新消息，用于触发终端进行配置更新的流程，具体方法可参考现有技术，这里不再赘述。
下面对上述步骤202中AMF判断终端当前是否存在目标业务的方法做具体介绍。
方法A，AMF根据第一指示信息，确定终端当前存在目标业务，该第一指示信息用于指示终端当前存在目标业务。
即AMF获取到第一指示信息后即可确定终端当前存在目标业务。其中，AMF获取到第一指示信息的方法具体又可以包括但不限于以下五种方法。
方法1，AMF向SMF发送第一订阅请求，该第一订阅请求用于当终端存在目标业务时，向AMF发送第一指示信息。
作为一种实现方式，当终端存在目标业务时，SMF向AMF发送第一指示信息，该第一指示信息中可以包括服务质量(Quality of Service，QoS)信息，其中，QoS信息包括分配和保留优先级(allocation and retention priority，ARP)，或者QoS信息包括5G Qos标识(5G QoS Identifier，5QI)，或者QoS信息包括ARP和5QI。当然，QoS信息也还可以包括其它信息。
其中，ARP包含了优先级水平，抢占能力(pre-emption capability)和被抢占属性(pre-emption vulnerability)等信息。优先级水平定义了一个资源请求的相对重要性。这样，在资源受限的情况下，能够决定一个新的QoS流应该被接受还是被拒绝。ARP优先级范围从1到15，1是最高优先级。抢占能力定义了一个具有较高优先级的数据流是否能够抢占一个已有的较低优先级的数据流的资源。被抢占属性定义数据流是否可能丢失分配给它的资源，以允许具有较高优先级的数据流使用这一资源。因此，当ARP包含了高优先级水平和/或包括了高抢占能力时，则该ARP的值可以用于指示目标业务，该目标业务即为需要保障业务连续性的业务，即不能中断的业务，比如可以是紧急业务，高优先级业务，或不能中断的基于IMS的业务等。5QI的值可以表示不同的QoS特性，比如优先级，数据包延迟，数据包错误率等。因此，当5QI包含了高优先级水平、和/或低数据包延迟、和/或低数据包错误率时，则该5QI的值可以用于指示目标业务。
从而AMF可以根据该QoS信息确定存在目标业务，具体的，AMF可以根据该QoS信息中包括的ARP和/或5QI确定存在目标业务。
例如，结合图2，在步骤202之前，还包括以下步骤：AMF向SMF发送第一订阅请求，该第一订阅请求用于当终端存在目标业务时，向AMF发送第一指示信息。该步骤可以是在步骤201之前执行，也可以是在步骤201之后且在步骤202之前执行。
因此，在步骤202之前，SMF若确定终端当前存在目标业务，则向AMF发送第一指示信息，从而AMF可以获取到第一指示信息。进而在步骤202中，AMF可以基于该第一指示信息，确定终端当前存在目标业务。
方法2，AMF向SMF发送第二订阅请求，该第二订阅请求用于当终端存在目标业务时，向AMF发送通知，AMF根据接收到的通知生成第一指示信息。
作为一种实现方式，当终端存在目标业务时，SMF向AMF发送通知，该通知中可以包括QoS信息，其中，QoS信息中包括ARP和/或5QI。该ARP的值可以用于指示目标业务，该5QI可以用于指示目标业务。具体可参考前述方法1中的相关描述。
从而AMF可以根据该QoS信息确定存在目标业务，进而可以生成第一指示信息。
例如，结合图2，在步骤202之前，还包括以下步骤：AMF向SMF发送第二订阅请求，该第二订阅请求用于当终端存在目标业务时，向AMF发送通知。该步骤可以是在步骤201之前执行，也可以是在步骤201之后且在步骤202之前执行。
因此，在步骤202之前，SMF若确定终端当前存在目标业务，则向AMF发送通知，AMF根据接收到的该通知生成第一指示信息。进而在步骤202中，AMF可以基于该第一指示信息，确定终端当前存在目标业务。
作为一种实现方式，SMF在确定终端当前存在目标业务时，发送的通知中例如可以包括业务的标识信息和用于指示该业务的类型为目标业务的指示信息，进而AMF根据该通知生成第一指示信息并存储于本地。
方法3，AMF向SMF发送请求消息，该请求消息用于请求查询终端当前是否存在目标业务；AMF接收来自AMF的响应消息，该响应消息包括第一指示信息。
例如，结合图2，在步骤202之后，还包括以下步骤：AMF向SMF发送请求消息，该请求消息用于请求查询终端当前是否存在目标业务；AMF接收来自AMF的响应消息，该响应消息包括第一指示信息。
作为一种实现方式，当终端存在目标业务时，SMF向AMF发送响应消息，该响应消息中包括第一指示信息，该第一指示信息中可以包括QoS信息，其中，QoS信息中包括ARP和/或5QI。该ARP的值可以用于指示目标业务，该5QI可以用于指示目标业务。具体可参考前述方法1中的相关描述。
从而AMF可以根据该QoS信息确定存在目标业务，进而可以生成第一指示信息。
该方法是由AMF主动向SMF发送请求消息，以查询终端当前是否存在目标业务。若SMF查询到终端当前存在目标业务，则向AMF发送第一指示信息。进而在步骤202中，AMF可以基于该第一指示信息，确定终端当前存在目标业务。
方法4，SMF向AMF发送第一指示信息。
该方法中，SMF不需要基于AMF的查询请求或订阅请求，而是在SMF确定终端存在目标业务时，向AMF发送第一指示信息，该第一指示信息用于指示终端存在目标业务，并且AMF可以存储该第一指示信息。其中，SMF获知终端当前存在目标业务的方式例如包括：SMF根据PDU会话中的QoS流对应的ARP和/或5QI，确定该PDU会话为包括目标业务的PDU会话等。
在一种实现方式中，SMF向AMF发送的第一指示信息可以是1个比特位的指示信息。 从而AMF可以根据该第一指示信息确定终端存在目标业务。AMF可以存储和PDU会话关联的该1比特位指示信息，或者存储存在目标业务的指示状态，从而在其他后续相关流程中，可以根据该指示信息确定存在目标业务。在又一种实现方式中，SMF向AMF发送的第一指示信息包括QoS信息，AMF存储该第一指示信息，其中，QoS信息中包括ARP和/或5QI，该ARP的值可以用于指示目标业务，该5QI可以用于指示目标业务。具体可参考前述方法1中的相关描述。从而AMF可以根据该第一指示信息中的ARP和/或5QI，确定终端存在目标业务。或者，AMF可以在接收到第一指示信息后，先存储该第一指示信息，后续需要判断终端是否存在目标业务时，可以根据该存储的第一指示信息中的ARP和/或5QI，确定终端存在目标业务。
方法5，SMF向AMF发送QoS信息，AMF根据QoS信息生成第一指示信息。AMF可以存储该QoS信息或存储根据QoS信息生成的第一指示信息。
该方法，SMF不需要判断终端是否存在目标业务，而是将业务的QoS信息发送给AMF，由AMF自己判断是否存在目标业务。AMF可以存储该QoS信息或存储根据QoS信息生成的第一指示信息。QoS信息中包括ARP和/或5QI。
其中，这里的ARP的值指示的业务可能是目标业务，也可能是非目标业务，这里的5QI指示的业务可能是目标业务，也可能是非目标业务。比如，当ARP的值指示的是高优先级或高抢占能力时，则该ARP的值指示的业务是目标业务；当ARP的值指示的是低优先级或低抢占能力时，则该ARP的值指示的业务是非目标业务(或称为普通业务)。同样的，当5QI的值指示的是高优先级、和/或低数据包延迟、和/或低数据包错误率时，则该5QI的值指示的业务是目标业务；当5QI的值指示的是低优先级、和/或高数据包延迟、和/或高数据包错误率，则该5QI的值指示的业务是非目标业务。
AMF在接收到SMF发送的QoS信息后，可以根据QoS信息中的ARP和/或5QI，判断是否存在目标业务，若确定存在目标业务则进一步的可以生成第一指示信息。需要说明的是，AMF可以存储该QoS信息，并在后续流程中判断是否存在目标业务；或者，在接收到该QoS信息后根据QoS信息中的ARP和/或5QI，判断终端是否存在目标业务，若确定终端存在目标业务则进一步的可以生成第一指示信息并存储该第一指示信息，该第一指示信息可用于在其他后续相关流程中，可以根据该第一指示信息确定终端存在目标业务。
其中，当SMF发送的QoS信息包括ARP，且ARP的值指示的是高优先级或高抢占能力时，则AMF可以确定该ARP的值指示的业务是目标业务，进而AMF可以确定终端当前存在目标业务。
当SMF发送的QoS信息包括5QI，且5QI用于指示的是高优先级、和/或低数据包延迟、和/或低数据包错误率时，则AMF可以确定该5QI的值指示的业务是目标业务，进而AMF可以确定终端当前存在目标业务。
当SMF发送的QoS信息包括ARP和5QI，且ARP的值指示的是高优先级或高抢占能力，或者，5QI用于指示的是高优先级、和/或低数据包延迟、和/或低数据包错误率，则AMF可以根据该ARP的值确定终端当前存在目标业务，或者，AMF可以根据该5QI的值确定终端当前存在目标业务，或者，AMF可以根据该ARP的值和5QI的值确定终端当 前存在目标业务。方法B，AMF接收来自终端的会话建立请求消息，会话建立请求消息包括第二指示信息，第二指示信息用于指示所建立的会话为目标业务的会话,AMF根据第二指示信息确定终端当前存在目标业务。
该方法B是在终端发起会话建立请求的过程中，AMF判断终端当前发起请求建立的会话是否为目标业务的会话，从而确定终端当前是否存在目标业务。
作为一种具体的实现方式，终端向AMF发送的会话建立请求消息中包括请求类型，该请求类型用于指示请求建立的会话为目标业务的会话，该目标业务可以是紧急业务或优先级业务等。从而，AMF可以根据该请求类型，确定终端请求建立的会话为目标业务的会话，进而确定终端当前存在目标业务。其中，上述请求类型即为上述第二指示信息的一种具体实现。
需要说明的是，上述终端向AMF发送会话建立请求消息的步骤可以是在图2所示的步骤202之前执行，例如可以是在步骤201之前执行，或者是在步骤201之后且在步骤202之前执行。
进一步地，在上述步骤203之后，还可以包括以下步骤204A，和/或，步骤204B。
步骤204A，AMF触发非目标业务的会话的释放或去激活的流程。
针对终端的非目标业务，即不需要保障业务连续性的业务，比如非紧急任务，非优先级任务等，AMF可以将这些非目标业务的会话释放掉，或者是去激活。
由于非目标业务已经提前结束，因此一旦目标业务结束，即可快速完成信令连接释放流程，使得终端进入空闲态。其中，信令连接释放可以包括接入网(access network，AN)释放或NAS信令连接释放等。
需要说明的是，上述非目标业务的会话，指的是只包括非目标业务的会话，由于该会话中只包括非目标业务，因而可以直接释放或者去激活。而针对既包括目标业务又包括非目标业务的会话，则不能直接释放，而是可以通过下述步骤204B来实现结束非目标业务。
步骤204B，AMF通知SMF：会话只为目标业务提供服务。
例如，针对会话A，该会话A中既包括目标业务a，又包括非目标业务b，则AMF可以通知SMF：该会话A为目标业务a提供服务。即通知SMF：该会话A只为目标业务a提供服务，不为非目标业务b提供服务。从而，SMF在接收到AMF的通知后，将不再为非目标业务b提供服务，可以理解为SMF结束了该非目标业务b。
由于非目标业务已经提前结束，因此一旦目标业务结束，即可快速完成信令连接释放流程，使得终端进入空闲态。
需要说明的是，由于步骤204A和步骤204B是针对不同类型的会话的执行操作，因此上述步骤204A和步骤204B之间没有必然的联系，即可以只执行步骤204A，也可以只执行步骤204B，还可以是既执行步骤204A又执行步骤204B。
进一步地，在上述步骤203之后，或者是在步骤204A之后，或者是在步骤204B之后，还包括以下步骤205。
步骤205，AMF若确定终端的目标业务已经结束，则向终端发送配置更新消息，配置更新消息用于指示终端进行配置更新。相应的，终端接收该配置更新消息。
即，AMF在确定终端的目标已经结束时，则确定可以继续执行终端的配置更新，因而向终端发送配置更新消息，该配置更新消息用于指示终端进行配置更新。
其中，终端在接收到该配置更新消息后，可以按照现有技术的流程，完成终端的配置过程。具体地，AMF会触发信令连接释放流程，进一步地，终端再发起注册流程，完成配置的更新。由于终端在配置更新过程中，已经没有目标业务在执行，从而有助于避免中断目标业务的执行。
作为一种实现方式，AMF可以通过以下步骤确定终端的目标业务已经结束：AMF向SMF发送第三订阅请求，该第三订阅请求用于当目标业务结束时，通知AMF。
需要说明的是，该步骤可以是在步骤205之前的任意步骤执行。
或者是，该步骤还可以与上述AMF发送第一订阅请求的步骤合并为一个步骤，即AMF在发送的第一订阅请求的同时还发送第三订阅请求，或者，第一订阅请求和第三订阅请求合并为一个订阅请求，该订阅请求可以同时完成第一订阅的请求和第三订阅请求的功能。
或者是，该步骤还可以与上述AMF发送第二订阅请求的步骤合并为一个步骤，即AMF在发送的第二订阅请求的同时还发送第三订阅请求，或者，第二订阅请求和第三订阅请求合并为一个订阅请求，该订阅请求可以同时完成第二订阅的请求和第三订阅请求的功能。
从而，AMF通过订阅的方式，在接收到SMF上报的目标业务结束的通知时，即可确定目标业务已经结束。
进一步地，在上述步骤205之后，还可以包括以下步骤206。
步骤206，终端向AMF发送配置更新完成消息，相应的，AMF接收该配置更新完成消息。
终端在完成配置更新时，可以发送一个配置更新完成消息，以通知AMF配置更新已经完成。
下面结合附图3-附图6，对图2所示的实施例的不同实现方式进行具体说明。
如图3所示，为本申请提供的一种更新配置的方法，包括以下步骤：
步骤301，AMF向SMF发送第一订阅请求，相应地，SMF接收该第一订阅请求。
AMF向SMF发送第一订阅请求，用于当终端存在目标业务时，向AMF发送所述第一指示信息。
步骤302，SMF向AMF发送第一指示信息，相应地，AMF接收第一指示信息。
该步骤为可选步骤。只有当SMF确定终端当前存在目标业务时，才向AMF发送第一指示信息。
步骤303-步骤306B，同图2所示的实施例中的步骤201-步骤204B，可参考前述描述。

作为一种可替代的实现方式，上述步骤609-步骤610还可以由以下步骤替换：SMF向AMF发送目标业务的会话释放的通知，相应地，AMF接收该通知。即，当目标业务的会话释放之后，SMF会主动通知AMF，该会话已经释放，从而AMF可以获知目标业务已经结束。
步骤611-步骤612，，同图2所示的实施例中的步骤205-步骤206，可参考前述描述。
步骤613，后续配置更新流程。可参考现有技术相关流程，例如可以参考3GPP TS 23.502:"Procedures for the 5G Sys tem；Stage 2"，这里不再赘述。
作为一种可替代的实现方式，若上述步骤602中携带的请求类型所指示建立的会话的类型为非目标业务会话，比如该请求类型是“普通请求(initial request)”，则在步骤602之后，可以先执行上述步骤604，再执行上述步骤605，然后再执行上述步骤603。并且，在步骤605的响应消息中还可以携带QoS信息，QoS信息中包括ARP和/或5QI，这里的ARP用于指示当前请求建立的会话对应的业务是一个目标业务，这里的5QI用于指示当前请求建立的会话对应的业务是一个目标业务。从而AMF在步骤603中可以根据该QoS信息确定终端存在目标业务。接着，再执行后续步骤606-步骤613。
如图7所示，为本申请提供的又一种更新配置的方法，该方法可用于解决背景技术中提到的问题。该方法中的AMF可以是图1所示的移动性管理网元，该方法中的SMF可以是图1所示的会话管理网元，该方法中的终端可以是图1所示的终端。该方法包括以下步骤：
步骤701，AMF确定需要更新终端的配置。
AMF确定需要更新终端的配置的方法，例如可以是AMF需要改变终端配置中终端接入和移动性管理相关参数，比如UDM网元通知AMF终端的签约信息需要更新，或者可以是网络切片配置改变等。
步骤702，AMF判断终端当前是否存在目标业务。
当AMF确定需要更新终端的配置时，则进一步判断终端当前是否存在目标业务。其中，该目标业务可以是需要保障业务连续性的业务，即不能中断的业务，比如可以是紧急业务，优先级业务，或不能中断的基于IMS的业务等。
步骤703，AMF若确定终端当前存在目标业务，则向终端发送配置更新消息且AMF不触发信令连接释放流程，该配置更新消息用于指示终端进行配置更新。
上述实施例，AMF在确定需要更新终端的配置时，首先判断终端当前是否存在目标业务，若确定存在目标业务，则仍然向终端发送配置更新消息，终端在接收到配置更新消息后，只是完成终端的配置，但AMF不触发信令连接释放流程，因而有助于避免中断目标业务的执行。AMF可等到目标业务执行完毕后再继续执行配置更新流程的后续流程，从而有助于在终端的配置更新流程中保障目标业务的连续性。
其中，上述步骤702中AMF判断终端当前是否存在目标业务的方法，可参考前述实施例的各种方法，例如可以使用图3所示的实施例的步骤301-步骤302的方法，或者还可以使用图4所示的实施例的步骤401-步骤402的方法，或者还可以使用图5所示的实施例的步骤502-503的方法，或者还可以使用图6所示的实施例的步骤602的方法，具体实现方式可参考前述描述，这里不再赘述。
进一步地，在上述步骤703之后，还可以包括步骤704。
步骤704，终端向AMF发送配置更新完成消息。
终端在完成配置更新时，可以发送一个配置更新完成消息，以通知AMF配置更新已经完成。
进一步地，在上述步骤703或步骤704之后，还可以包括以下步骤705A，和/或，步骤705B。
步骤705A，AMF触发非目标业务的会话的释放或去激活的流程。
步骤705B，AMF通知SMF：会话只为目标业务提供服务。
上述步骤705A-步骤705B，与图2所示的实施例的步骤204A-步骤204B相同，可参考前述描述。
作为另一种实现方式，上述步骤705A的执行为有条件执行。比如作为一种实现方式，上述步骤702中若确定存在目标业务，且该目标业务不是紧急业务或高优先级业务，则AMF启动定时器，可选的还可以将该定时器携带于步骤703的配置更新消息中发送至终端。若定时器超时且终端为连接态，则执行步骤705A，可选的，在执行步骤705A时 还可以执行目标业务的会话的释放或去激活的流程。若定时器超时前，AMF确定终端出现紧急业务或高优先级业务，则AMF停止定时器，并且不执行步骤705A。即，只有在定时器超时后才执行步骤705A。当步骤703的配置更新消息携带定时器时，若定时器超时前终端未出现紧急业务或高优先级业务，则终端可以获知AMF将会执行步骤705A，可选的，在执行步骤705A时AMF还可以执行目标业务的会话的释放或去激活的流程，若定时器超时前终端出现紧急业务或高优先级业务，则终端可以停止定时器且终端可以获知AMF未执行步骤705A。
进一步地，在上述步骤703或步骤704之后，还可以包括以下步骤706和步骤707。
步骤706，AMF向SMF发送第三订阅请求，相应地，SMF接收该第三订阅请求。
该第三订阅请求用于当目标业务结束时，通知AMF。
步骤707，SMF若确定目标业务已经结束，则通知AMF目标业务已经结束。
需要说明的是，该步骤706-步骤707的具体实现方法，可采用图3所示的实施例中所描述的执行方法，或者是采用图4所示的实施例中所描述的执行方法，或者是采用图5所示的实施例中所描述的执行方法，或者是采用图6所示的实施例中所描述的执行方法。
下面介绍上述步骤703中，AMF向终端发送配置更新消息且AMF不触发信令连接释放流程的具体实现方法。
方法一，AMF向终端发送第三指示信息，该第三指示信息用于指示终端在信令连接释放之后发起注册流程。
其中，第三指示信息可以是单独发送至终端的，也可以是携带于配置更新消息中发送至终端。
通过该方法，终端接收到配置更新消息后，完成终端的配置更新，然后依据该第三指示信息，暂时不发起注册流程，而是等待信令连接释放之后再发起注册流程。从而终端在执行配置更新之后，进入等待模式，直到终端确认信令连接释放之后，才发起注册流程。例如，终端在进入空闲态后，即可确认信令连接释放，这时可以发起注册流程。
在该方法中，AMF通过上述步骤706-步骤707的方式，当终端的目标业务已经结束时，AMF可以获知终端的目标业务已经结束，进而AMF可以发起信令连接释放流程，完成信令连接释放。当信令连接释放之后，终端进入空闲态。终端进入空闲态之后，表明信令连接已经释放，进而再发起注册流程。
方法二，AMF向终端发送的配置更新消息中包括修改后的配置更新参数，其中该配置更新参数被修改的参数为目标参数，该目标参数为配置更新时会触发信令连接释放的参数。
例如，该目标参数使用参数A来表示，则配置更新消息中包括配置更新参数，配置更新参数中包括参数A。若按照现有技术的方式发送配置更新参数，则终端在接收到配置更新消息后，根据配置更新参数中的参数A，会触发终端发起信令连接释放的流程。
而根据本申请的方法，通过对参数A进行修改，使得修改后的参数A不会触发信令连接释放流程，从而终端在接收到配置更新消息之后，从中获取到配置更新参数，依据配置更新参数终端修改后的参数A，则终端将不会触发信令连接释放流程。
若采用该方法二，则进一步地，AMF若确定目标业务已经结束，则触发重新进行终端的配置更新流程。即，由于之前使使用了修改后的配置更新参数触发终端的配置更新，因此终端的配置更新可能不是很准确，因此AMF在确定目标业务已经结束时，可以通过触发重新进行终端的配置流程，以实现对终端的配置进行正确更新。
方法三，AMF向终端发送第四指示信息，该第四指示信息用于指示终端在目标业务结束之后发起注册流程。
其中，第四指示信息可以是单独发送至终端的，也可以是携带于配置更新消息中发送至终端。
通过该方法，终端接收到配置更新消息后，完成终端的配置更新，然后依据该第四指示信息，暂时不发起注册流程，而是等待目标业务结束之后再发起注册流程。从而终端在执行配置更新之后，进入等待模式，直到终端确认目标业务结束之后，才发起注册流程。例如，终端可以根据目标业务对应的会话释放确定目标业务已结束，或者根据目标业务对应的应用已关闭(如目标业务对应的应用的Socket关闭)确定目标业务已结束。终端在确认目标业务已经结束，然后再发起注册流程。
方法四，移动性管理网元向终端发送配置更新消息，该配置更新消息用于指示终端发起注册流程。
终端若判断存在目标业务，则等待目标业务结束后再发起注册流程。例如，终端可以根据目标业务对应的会话释放确定目标业务已结束，或者根据目标业务对应的应用已关闭(如目标业务对应的应用的Socket关闭)确定目标业务已结束。终端在确认目标业务已经结束，然后再发起注册流程。
该方法四与上述方法三的主要区别在于：该方法四的配置更新消息中不携带上述第四指示信息，终端在接收到配置更新消息后，采用预先设定的方法，先判断终端当前是否存在目标业务，若存在则先发起注册请求。直到确定当前不存在目标业务时，再发起注册流程。
下面结合图8-图10，对图7所示的实施例的不同实现方式进行具体说明。
如图8所示，为本申请提供的一种更新配置的方法，包括以下步骤：
步骤801-步骤807，与图7所示的实施例中的步骤701-步骤707相同。
其中，步骤803中的配置更新消息是采用图7所示的实施例所描述的方法二实现的，即配置更新消息中携带的是修改后的配置更新参数，其中配置更新参数中被修改的参数为目标参数，该目标参数在修改之前会触发信令连接释放流程，而在修改之后则不会触发信令连接释放流程。
作为另一种实现方式，上述步骤805A的执行为有条件执行。比如作为一种实现方式，上述步骤802中若确定存在目标业务，且该目标业务不是紧急业务或高优先级业务，则AMF启动定时器，可选的还可以将该定时器携带于步骤803的配置更新消息中发送至终端。若定时器超时且终端为连接态，则执行步骤805A，可选的，在执行步骤805A时还可以执行目标业务的会话的释放或去激活的流程。若定时器超时前，AMF确定终端出现紧急业务或高优先级业务，则AMF停止定时器，并且不执行步骤805A。即，只有在 定时器超时后才执行步骤805A。当步骤803的配置更新消息携带定时器时，若定时器超时前终端未出现紧急业务或高优先级业务，则终端可以获知AMF将会执行步骤805A，可选的，在执行步骤805A时AMF还可以执行目标业务的会话的释放或去激活的流程，若定时器超时前终端出现紧急业务或高优先级业务，则终端可以停止定时器且终端可以获知AMF未执行步骤805A。
步骤808，AMF确定终端的目标业务已经结束。
即通过步骤806和步骤807的方式，AMF通过向SMF订阅的方式，当终端的目标业务结束时，SMF会通知AMF。
步骤809，AMF触发重新进行终端的配置更新流程。
由于此时终端已经没有目标业务才执行，因而该步骤809可使用现有技术的方法，重新进行终端的配置更新流程，完成终端的配置更新。
如图9所示，为本申请提供的一种更新配置的方法，包括以下步骤：
步骤901-步骤902，与图7所示的实施例中的步骤701-步骤702相同。
步骤903A，AMF向终端发送配置更新消息，相应地，终端接收配置更新消息。
该配置更新消息与现有技术的配置更新消息相同，用于指示终端进行配置更新。
步骤903B，AMF向终端发送第三指示信息，相应地，终端接收第三指示信息。
该第三指示信息用于指示终端在信令连接释放之后发起注册流程。
即通过第三指示信息，指示终端只进行配置更新，且在信令连接释放之后再发起注册流程，有助于保障目标业务的连续执行。
需要说明的是，上述步骤903A和步骤903B还可以合并为一个步骤，即在903A的配置更新消息中携带第三指示信息，即对现有的配置更新消息进行修改，从中插入一个第三指示信息，或者是对配置更新消息中的某个信息进行修改以得到第三指示信息。
步骤904-步骤907，与图7所示的实施例中的步骤704-步骤707相同。
作为另一种实现方式，上述步骤905A的执行为有条件执行。比如作为一种实现方式，上述步骤902中若确定存在目标业务，且该目标业务不是紧急业务或高优先级业务，则AMF启动定时器，可选的还可以将该定时器携带于步骤903A的配置更新消息中发送至终端。若定时器超时且终端为连接态，则执行步骤905A，可选的，在执行步骤905A时还可以执行目标业务的会话的释放或去激活的流程。若定时器超时前，AMF确定终端出现紧急业务或高优先级业务，则AMF停止定时器并且不执行步骤905A。即，只有在定时器超时后才执行步骤905A。当步骤903A的配置更新消息携带定时器时，若定时器超时前终端未出现紧急业务或高优先级业务，则终端可以获知AMF将会执行步骤905A，可选的，在执行步骤905A时AMF还可以执行目标业务的会话的释放或去激活的流程，若定时器超时前终端出现紧急业务或高优先级业务，则终端可以停止定时器且终端可以获知AMF未执行步骤905A。
步骤908，AMF确定终端的目标业务已经结束。
即通过步骤906和步骤907的方式，AMF通过向SMF订阅的方式，当终端的目标业务结束时，SMF会通知AMF。
步骤909，AMF触发信令连接释放流程。
即AMF在确定终端的目标业务已经结束时，则触发信令连接释放流程。由于此时目标业务已经结束，因而信令连接释放不会破坏目标业务的执行。
步骤910，终端发起注册流程。
由于在AMF完成了信令连接释放，因而终端进入空闲态，进而终端即可确定信令连接已经释放，从而发起注册流程，实现将终端更新后的配置注册至网络。
如图10所示，为本申请提供的又一种更新配置的方法，包括以下步骤：
步骤1001-步骤1002，与图9所示的实施例中的步骤901-步骤902相同。
步骤1003A，AMF向终端发送配置更新消息，相应地，终端接收配置更新消息。
该配置更新消息与现有技术的配置更新消息相同，用于指示终端进行配置更新。
步骤1003B，AMF向终端发送第四指示信息，相应地，终端接收第四指示信息。
该第四指示信息用于指示终端在目标业务结束后发起注册流程。
即通过该第四指示信息，指示终端在确认目标业务已经结束时，再发起注册流程，，有助于保障目标业务的连续执行。
作为一种实现方式，上述步骤1003A和步骤1003B还可以合并为一个步骤，即在1003A的配置更新消息中携带上述指示信息，即对现有的配置更新消息进行修改，从中插入一个指示信息，或者是对配置更新消息中的某个信息进行修改以得到指示信息。
作为又一种实现方式，还可以删除上述步骤1003B，且上述步骤1003A的配置更新消息还可以用于指示终端发起注册流程。
步骤1004-步骤1005B，与图9所示的实施例中的步骤904-步骤905B相同。
作为另一种实现方式，上述步骤1005A的执行为有条件执行。比如作为一种实现方式，上述步骤1002中若确定存在目标业务，且该目标业务不是紧急业务或高优先级业务，则AMF启动定时器，可选的还可以将该定时器携带于步骤1003A的配置更新消息中发送至终端。若定时器超时且终端为连接态，则执行步骤1005A，可选的，在执行步骤1005A时还可以执行目标业务的会话的释放或去激活的流程。。若定时器超时前，AMF确定终端出现紧急业务或高优先级业务，则AMF停止定时器并且不执行步骤1005A即，只有在定时器超时后才执行步骤1005A。当步骤1003A的配置更新消息携带定时器时，若定时器超时前终端未出现紧急业务或高优先级业务，则终端可以获知AMF将会执行步骤1005A，可选的，在执行步骤1005A时AMF还可以执行目标业务的会话的释放或去激活的流程，若定时器超时前终端出现紧急业务或高优先级业务，则终端可以停止定时器且终端可以获知AMF未执行步骤1005A。
步骤1006，终端根据配置更新消息，更新配置。
即终端根据配置更新消息中的相关参数，对终端的配置做更新。
步骤1007，终端确定目标业务已经结束。
例如，终端根据目标业务对应的会话释放确定目标业务已经结束。或者，终端根据目标业务对应的应用已关闭确定目标业务已经结束。
需要说明的是，上述步骤1006和步骤1007之间没有严格的执行顺序。即可以先执 行步骤1006，再执行步骤1007，也可以是先执行步骤1007，再执行步骤1006。
步骤1008，终端发起注册流程。
终端发起注册流程，可以将终端更新后的配置注册至网络。
上述方法，移动性管理网元在需要更新终端的配置时，若确定终端当前存在目标业务，则仍然向终端发送配置更新消息，且在配置更新消息中携带指示信息，该指示信息用于指示终端在确定目标业务结束后发起注册流程，即由终端自身确定目标业务结束后主动发起注册流程。由于终端是在目标业务结束后发起注册流程，因而不会影响目标业务的正常执行，有助于保障目标业务的连续性。
基于相同的发明构思，如图11所示，为本申请提供的一种装置示意图，该装置可以是移动性管理网元或芯片，可执行上述任一实施例的方法。

针对上述图2-图9所示的任一实施例，若由于终端的移动性导致AMF的切换，则切换前的AMF(例如称为AMF1)可以通知切换后的AMF(例如称为AMF2)：终端的配置的更新暂未完成。接着，后续由切换前的AMF完成的操作，可以更新为由切换后的AMF完成，或者由切换前的AMF和切换后的AMF共同完成。其中，切换前的AMF1是切换前为终端提供服务的AMF，切换后的AMF2是切换后为终端提供服务的AMF。
下面以图2和图3为例，分别将图2和图3所示的实施例扩展到AMF的切换场景。对于图4-图10所示的实施例，也可以按照同样的方法扩展到AMF的切换场景，不再赘述。
如图13所示，为本申请提供一种更新配置的方法，该方法是针对图2所示的实施例扩展到AMF的切换场景。其中，图13所示的实施例中的AMF1为切换前的AMF，也即图2所示的AMF，图13所示的AMF2为切换后的AMF。该方法包括以下步骤：
步骤1301-步骤1304B，与图2所示的实施例中的步骤201-步骤204B相同，可参考前述描述，这里不再赘述。
步骤1305，AMF1通知AMF2：终端的配置的更新暂未完成。
当执行终端的配置的更新时，若因终端的移动，触发为终端提供服务的移动性管理网元由AMF1切换为AMF2，则AMF1可以通知AMF2：终端的配置的更新暂未完成。
作为一种实现方式，AMF1可以向AMF2发送一个指示信息，该指示信息用于通知AMF2，终端的配置的更新暂未完成，也即：终端的配置的更新还未完成。该指示信息可以是独立发送的，也可以包括在AMF1向AMF2发送的终端的上下文信息中。这里的指示信息可以称为第五指示信息。
进一步地，在上述步骤1305之后，还可以包括以下步骤1306。
步骤1306，AMF2若确定终端的目标业务已经结束，则向终端发送配置更新消息，配置更新消息用于指示终端进行配置更新。相应的，终端接收该配置更新消息。
进一步地，在上述步骤1306之后，还可以包括以下步骤1307。
步骤1307，终端向AMF2发送配置更新完成消息，相应的，AMF2接收该配置更新完成消息。
上述步骤1306-步骤1307的具体实现细节，可参考图2所示的步骤205-步骤206，这里不再赘述。该1306-步骤1307与上述步骤205-步骤206的主要区别在于，执行主体由AMF1变为AMF2。
上述实施例，AMF1在确定需要更新终端的配置时，首先判断终端当前是否存在目标业务，若确定存在目标业务，则暂停执行更新终端的配置，有助于避免中断目标业务的执行。若发生AMF切换，由AMF1切换为AMF2，则AMF1可以通知AMF2终端的配置的更新暂未完成，从而后续等到目标业务执行完毕后，可由AMF2再继续执行更新终端的配置，从而有助于在终端的配置更新流程中保障目标业务的连续性。
如图14所示，为本申请提供的另一种更新配置的方法，该方法是针对图3所示的实施例扩展到AMF的切换场景。其中，图14所示的实施例中的AMF1为切换前的AMF，也即图3所示的AMF，图14所示的AMF2为切换后的AMF。该方法包括以下步骤：
步骤1401-步骤1407，与图3所示的实施例中的步骤301-步骤307相同，可参考前述描述，这里不再赘述。
当执行终端的配置的更新时，若因终端的移动，触发为终端提供服务的移动性管理网元由AMF1切换为AMF2，则AMF1可以通知AMF2：终端的配置的更新暂未完成。
本申请实施例中，AMF1通知AMF2终端的配置的更新暂未完成的具体方法至少可以包括以下两种方案，下面分别说明。
方案A，AMF1通知AMF2终端的配置的更新暂未完成，是在AMF1等待接收目标业务结束通知的过程中完成的，即AMF1通知AMF2终端的配置的更新暂未完成时，AMF1还没有接收到SMF发送的目标业务已经结束的通知。作为示例，方案A可以通过以下步骤1408-步骤1410实现。
步骤1408，AMF1通知AMF2：终端的配置的更新暂未完成。
作为一种实现方式，AMF1可以向AMF2发送第五指示信息，该第五指示信息用于通知AMF2终端的配置的更新暂未完成。可选的，该步骤1408中，AMF1在发送第五指示信息的同时还可以发送第六指示信息，该第六指示信息用于指示AMF2向SMF发送第四订阅请求，该第四订阅请求用于请求当目标业务结束时通知AMF2。AMF2在接收到第六指示信息后执行以下步骤1409，即第六指示信息可用于触发AMF2向SMF发送第四订阅请求。或者，AMF1只发送第五指示信息，不发送第六指示信息，当AMF2接收到第五指示信息后确定终端的配置的更新暂未完成，进而继续执行步骤1409。上述第五指示信息可以是独立发送的，也可以包括在AMF1向AMF2发送的终端的上下文信息中。若发送该第六指示信息，则第六指示信息可以是独立发送的，也可以包含在AMF1向AMF2发送的终端的上下文信息中。
作为示例，下面给出上述第六指示信息的具体实现方法。
方法一，上述第六指示信息可以包括第三订阅请求的相关信息，则AMF2在接收到该第三订阅请求的相关信息后，可以确定终端的配置的更新暂未完成，进而可以触发AMF2执行以下步骤1409。
方法二，上述第六指示信息可以包括终端的更新前的配置信息和终端的更新后的配置信息，当AMF2接收到这些信息后，若确定终端的更新前的配置信息与终端的更新后的配置信息不同，则可以确定终端的配置的更新未完成，进而可以触发AMF2执行以下步骤1409。
方法三，上述第六指示信息可以是1比特的指示信息，比如第六指示信息为“0”，则用于指示AMF2向SMF发送第四订阅请求，即触发AMF2执行以下步骤1409，或者第六指示信息为“1”时，用于指示AMF2向SMF发送第四订阅请求。
需要说明的是，若终端此时向AMF2发送PDU会话建立请求，此时AMF2可以拒绝该PDU会话建立请求，并向终端返回拒绝响应。可选的，该拒绝响应中还可以包括拒绝的原因。
步骤1409，AMF2向SMF发送第四订阅请求。
该第四订阅请求，用于请求当目标业务结束时通知该AMF2。
作为一种实现方式，在上述步骤1409之后，SMF还可以通知AMF1取消上述第三订阅请求。即由AMF1订阅目标业务结束通知修改为AMF2订阅目标业务结束通知。
步骤1410，SMF若确定目标业务已经结束，则通知AMF2目标业务已经结束。
通过上述步骤1408-步骤1410，当AMF1未接收到目标业务已经结束的通知，则不继续等待，而是通过步骤1408直接通知AMF2：终端的配置的更新暂未完成，同时还触发AMF2继续向SMF订阅目标业务的结束通知，即触发AMF2通过步骤1409向SMF发送第四订阅请求，从而后续若SMF确定目标业务已经结束，则直接通知AMF2。
方案B，AMF1是在接收到目标业务结束通知后通知AMF2终端的配置的更新暂未完成。作为示例，方案B可以通过以下步骤1411-步骤1412实现。
步骤1411，SMF若确定目标业务已经结束，则通知AMF1目标业务已经结束。
该步骤1411与图3所示的步骤308相同，可参考前述描述。
步骤1412，AMF1通知AMF2：终端的配置的更新暂未完成。
作为一种实现方式，AMF1可以向AMF2发送第五指示信息，该第五指示信息用于通知AMF2终端的配置的更新暂未完成。
作为又一种实现方式，AMF1还可以在该步骤1408中向AMF2发送终端的更新前的配置信息和终端的更新后的配置信息，当AMF2接收到这些信息后，若确定终端的更新前的配置信息与终端的更新后的配置信息不同，则可以确定终端的配置的更新未完成。
通过上述步骤1411-步骤1412，当AMF1未接收到目标业务已经结束的通知，则继续等待，直到通过上述步骤1411接收到目标业务已经结束的通知后，再通过步骤1412通知AMF2：终端的配置的更新暂未完成，并且无需触发AMF2向SMF订阅目标业务已经结束的通知。
在上述步骤1408-步骤1410之后，或者在上述步骤1411-步骤1412之后，还可以包括以下步骤1413-步骤1415。
步骤1413-步骤1414，与图13所示的实施例中的步骤1306-步骤1307相同，可参考前述描述，这里不再赘述。
步骤1415，后续配置更新流程。可参考现有技术相关流程，例如可以参考3GPP TS 23.502:"Procedures for the 5G System；Stage 2"，这里不再赘述。
上述实施例，AMF1在确定需要更新终端的配置时，首先判断终端当前是否存在目标业务，若确定存在目标业务，则暂停执行更新终端的配置，有助于避免中断目标业务的执行。若发生AMF切换，由AMF1切换为AMF2，则AMF1可以通知AMF2终端的配置的 更新暂未完成，从而后续等到目标业务执行完毕后，可由AMF2再继续执行更新终端的配置，从而有助于在终端的配置更新流程中保障目标业务的连续性。
针对上述图2-图6所示的任一实施例，若是由UDM网元(以下简称UDM)触发AMF对终端的配置进行更新，则AMF在确定当前存在目标业务则暂停执行更新终端的配置时，还可以通知UDM：配置更新失败或配置更新暂停。从而以便于UDM可以继续等待或重新发起配置更新的流程。下面以图2为例，将图2所示的实施例扩展到通知UDM配置更新的结果的应用场景。对于图3-图6所示的实施例，也可以按照同样的方法扩展到通知UDM配置更新结果的应用场景，不再赘述。
如图15所示，为本申请提供一种更新配置的方法，包括以下步骤：
步骤1501，UDM触发终端的配置的更新。
UDM触发终端的配置的更新的方法，例如可以是UDM通知AMF：终端的签约信息需要更新等。
步骤1502-步骤1503，与图2所示的实施例步骤202-步骤203相同，可参考前述描述。
步骤1504，AMF通知UDM配置更新暂停或者失败。
在上述步骤1503中，AMF若确定终端当前存在目标业务，则暂停执行更新终端的配置，接着AMF可以通知UDM终端的配置更新暂停或失败。
在一种实现方式中，AMF在该步骤1504中可以通知UDM配置更新暂停。进一步的，UDM在接收到配置更新暂停后，可以启动定时器。若UDM的定时器超时前，UDM始终未收到步骤1508的配置更新成功的通知，则UDM可以确定终端的配置更新失败。可选的，在AMF上也可以设置一个与UDM相同的的定时器。若终端当前一直存在目标业务，则AMF将不会启动执行更新终端的配置，AMF上的定时器将会超时，从而AMF也可以确定终端的配置更新失败，则步骤1508将不会被执行。进一步的，UDM在确定配置更新失败之后，可以根据自身配置的策略信息触发UDM后续再次发起终端的配置更新，或者可以启动另一个定时器，该定时器用于触发UDM后续再次发起终端的配置的更新。
在又一种实现方式中，AMF在该步骤1504中还可以通知UDM配置更新失败。进一步的，UDM在确定配置更新失败之后，可以根据自身配置的策略信息触发UDM后续再次发起终端的配置更新，或者还可以启动另一个定时器，该定时器用于触发UDM后续再次发起终端的配置更新。
在一种实现方式中，在步骤1503之后，若AMF确定配置更新失败(比如AMF的定时器超时)，则可以停止执行后续步骤1505A-步骤1508。在又一种实现方式中，在步骤1503之后，若AMF的定时器超时前，AMF确定终端当前不存在目标业务，则AMF可以继续执行后续步骤1505A-步骤1508。
步骤1505A-步骤1507，与图2所示的实施例步骤204A-步骤206相同，可参考前述描述。
需要说明的是，上述步骤1504和步骤1505A-步骤1505B之间没有严格的执行顺序。即可以先执行步骤1504，再执行步骤1505A和步骤1505B。也可以是先执行步骤1505A 和步骤1505B，再执行步骤1504。或者还可以向执行步骤1505A，再执行步骤1504，再执行1505B。或者还可以向执行步骤1505B，再执行步骤1504，再执行步骤1505A。
步骤1508，AMF通知UDM配置更新成功。
若AMF完成了对终端的配置的更新，则可以向UDM发送配置更新成功。
在一种实现方式中，若在执行步骤1508之前，AMF在上述步骤1504中向UDM发送了配置更新暂停，则会触发UDM启动定时器。此时，执行步骤1508之后，若UDM中的定时器在接收到配置更新成功时未超时，则UDM可停止该定时器。并且UDM不会触发重新发起终端的配置的更新。
在又一种实现方式中，若在执行步骤1508之前，AMF在上述步骤1504中向UDM发送了配置更新暂停，则会触发UDM启动定时器。此时，执行步骤1508之后，若UDM中的定时器在接收到配置更新成功前已经超时，则UDM将会触发重新发起终端的配置的更新。
在一种实现方式中，UDM触发重新发起终端的配置的更新时，可以根据与上次发起终端的配置的更新时的相同的配置，发起终端的配置的更新，此时在终端不存在目前业务的前提下，若步骤150A-步骤1507未执行，则先执行步骤150A-步骤1507，再执行步骤1508，若步骤150A-步骤1507已经执行，则不再执行步骤150A-步骤1507，而是直接执行步骤1508。
在又一种实现方式中，UDM触发重新发起终端的配置更新时，可以根据与上次发起终端的配置更新时的不同的配置，重新发起终端的配置的更新。
需要说明的是，该步骤1508中，AMF可以向UDM发送一个指示信息，该指示信息用于指示配置更新成功。该指示信息可以是携带于指示消息中发送的，该指示信息也可以是其他消息中的原因值，该指示信息还可以是独立发送的。
上述实施例，AMF在确定需要更新终端的配置时，首先判断终端当前是否存在目标业务，若确定存在目标业务，则暂停执行更新终端的配置，有助于避免中断目标业务的执行。后续等到目标业务执行完毕后，可由AMF再继续执行更新终端的配置，从而有助于在终端的配置更新流程中保障目标业务的连续性。并且，AMF还可以向UDM发送配置更新暂停或失败，从而可以触发UDM重新发起配置更新的流程。
