下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的网络的转移方法进行详细地说明。
本申请实施例提供了一种网络的转移方法，图2是本申请实施例的网络 的转移方法流程图一，如图2所示，该方法的步骤包括：
步骤S202，终端获取终端当前执行的业务；
步骤S204，终端在终端当前执行的业务中不存在目标业务的情况下，释放终端当前执行的业务；
步骤S206，终端在释放终端当前执行的业务后，执行对终端的网络转移。
通过本申请实施例中的上述步骤S202至步骤S206，终端可以在当前执行的业务中不存在目标业务的情况下，释放终端当前执行的业务，进而进行网络的转移，如果该目标业务是高优先级业务，则可以是在终端当前执行的业务中不存在高优先级业务的情况下，释放当前执行的业务并进行网络转移；此外，该目标业务也可以是终端指定的一个或多个业务，即如果终端当前执行的业务中不存在这些指定的一个或多个业务，也是可以释放当前执行的业务并进行网络转移，从而解决了现有技术中终端当前存在不重要的业务的情况下，终端会持续驻留在当前的网络无法实现网络的转移的问题。
在本申请实施例的具体应用场景中，本申请实施例中的目标业务优选为业务优先级高于预设优先级的业务。
可选地，在本申请实施例中对于终端确定当前执行的业务中是否存在目标业务的方式，可以包括如下两种方式：
方式1)根据网络侧设备发送的EXT-SOR对应的第一信息来确定，具体步骤如下：
步骤S11，终端接收网络侧设备发送的扩展的漫游控制EXT-SOR对应的第一信息；
步骤S12，终端根据第一信息确定当前执行的业务中是否存在目标业务；其中，第一信息用于指示具有目标信息的业务为目标业务。
方式2)终端自主确定当前执行的业务中是否存在目标业务。
也就是说，在本申请实施例中，对于终端确定当前执行的业务中是否存在目标业务的方式，可以由终端自主确定当前执行的业务中是否存在目标业务的方式，也可以是由网络侧设备所发送的信息来确定。
对于上述方式1)，在本申请实施例的可选实施方式中，该第一信息中的目标信息包括以下至少一项：目标业务的类型、目标业务的名称、目标业务 的号码、目标单个网络切片选择辅助信息(Single Network Slice Selection Assistance Information，S-NSSAI)、目标数据网络名称(Data Network Name，DNN)、目标5G服务质量标识(5G Quality of Service Identifier，5QI)、目标PDU会话的请求类型、目标网际互连协议(Internet Protocol，IP)地址、目标分组过滤器。
也就是说，属于目标S-NSSAI的协议数据单元(Protocol Data Unit，PDU)会话上的业务属于高优先级业务；连接到目标数据网络(DNN/APN)的业务属于高优先级业务；属于目标5QI的业务属于高优先级业务；某些PDU SESSION的Request type信息；使用目标PDU SESSION的Request type建立起来的PDU SESSION的业务属于高优先级业务，例如“initial emergency request”，“existing emergency PDU session”，“MA PDU request”。PDU SESSION的IP地址目标某些IP地址的PDU SESSION属于高优先级业务；UE的目标通信IP地址属于哪些地址范围的业务属于高优先级业务；包含目标Packet filter的PDU SESSION/QOS FLOW上的业务属于高优先级业务。
此外，对于上述方式1)需要说明的是，终端接收网络侧设备通过以下至少之一承载发送的第一信息：SOR的透传容器、EXT-SOR的透传容器(EXT-SOR transparent container)。其中，SOR的透传容器或EXT-SOR的透传容器包括以下至少一项：EXT-SOR信息1、EXT-SOR信息2、EXT-SOR的安全信息。
如表1所示，IEI为73的IE为SOR的透传容器；
Figure PCTCN2021111505-appb-000001
Figure PCTCN2021111505-appb-000002

需要说明的是，SOR透明容器是类型6信息元素，最小长度为20个八位位组，如表2和表3所示，其中，包括EXT-SOR的信息1和EXT-SOR的信息2：
Figure PCTCN2021111505-appb-000003
表2
Figure PCTCN2021111505-appb-000004
表3
其中，上述表2和表3指示SOR(transparent container information element)携带经过保护的EXT-SOR相关的信息。其中，EXT-SOR信息1和信息2为新增的承载EXT-SOR相关的信息中的部分信息，如指示高优先级业务的信息；SOR header-new、SOR-MAC-IAUSF-new、CounterSOR-new为需要修改的部分，需要修改为能指示SOR transparent container IE中包含了EXT-SOR信息1(经过USIM等保护的EXT-SOR相关的信息)或EXT-SOR信息2(未经过USIM等保护的EXT-SOR相关的信息)，以及相关的安全信息，如表4所示：
Figure PCTCN2021111505-appb-000005
表4
其中，是否携带EXT-SOR信息(octet 4,bit 6)：
0表示SOR transparent container不携带EXT-SOR信息；
1表示SOR transparent container携带EXT-SOR信息；
另外，SOR-MAC-IAUSF-new的计算也对应SOR transparent container IE的内容。即SOR transparent container IE中若携带EXT-SOR，则SOR-MAC-IAUSF-new的计算过程也包含了EXT-SOR；SOR transparent container IE若不携带EXT-SOR，则SOR-MAC-IAUSF-new的计算过程就不包含EXT-SOR；
CounterSOR-new也对应SOR transparent container IE的内容。即，SOR transparent container IE中若携带EXT-SOR，则SOR-MAC-IAUSF-new的计算过程也体现了EXT-SOR的存在(或传输)；SOR transparent container IE若不携带EXT-SOR，则SOR-MAC-IAUSF-new的计算过程就不体现EXT-SOR的存在(或传输)。
如表5所示，IE中还包括EXT-SOR的透传容器；

Figure PCTCN2021111505-appb-000007
表5
其中，EXT-SOR的透传容器用于携带EXT-SOR相关的信息的IE，如携带EXT-SOR信息1或2，同时可以携带EXT-SOR的安全信息，如MAC，counter，等。如表6所示：
Figure PCTCN2021111505-appb-000008
表6
其中，EXT-SOR header指示EXT-SOR的特征，如：是网络发给UE的EXT-SOR信息，还是UE发给网络的EXT-SOR信息；EXT-SOR信息的有效范围，如是否有时间限制，是否有PLMN限制，等；
EXT-SOR-MAC-1表示对EXT-SOR信息1或2执行完整性保护算法后生成的校验和；
CounterEXT-SOR表示对EXT-SOR信息1或2执行完整性保护算法所需要的计数值。
在本申请实施例的可选实施方式中，基于上述方式1)，上述步骤S11中 涉及到的接收网络侧设备发送的扩展的漫游控制EXT-SOR对应的第一信息的方式，进一步可以包括：
步骤S11-1，终端向网络侧设备发送通知消息；其中，通知消息用于向网络侧设备通知终端支持EXT-SOR能力；
步骤S11-2，终端接收网络侧设备发送的与EXT-SOR对应的第一信息。
对于上述步骤S11-1中涉及到的终端向网络侧设备发送通知消息的方式，对于网络侧设备而言，在具体应用场景中以注册请求消息向网络侧设备通知终端支持EXT-SOR能力为例，其过程包括：
步骤S21，网络侧设备检查终端发来的注册请求消息中是否指示了“UE支持EXT-SOR能力”。若指示了，执行步骤S23，否则执行步骤22.
步骤S22，网络侧设备确定终端不支持EXT-SOR功能；
步骤S23，网络侧设备确定终端支持EXT-SOR功能。VPLMN AMF需要从HPLMN获取该UE的EXT-SOR相关的信息；
步骤S24，AMF判断：自己是否已有最新的EXT-SOR相关的信息；若已有了，执行步骤S25；若没有，执行步骤S26；
步骤S25，有些特殊场景下，如初始注册，紧急注册等，归属公用陆地移动网络(Home Public Land Mobile Network，HPLMN)统一数据管理(Unified Data Management，UDM)可以要求接入移动性管理功能(Access and Mobility Management Function，AMF)从HPLMN UDM那么重新获取EXT-SOR相关的信息。因此，访问(Visited Public Land Mobile Network，VPLMN)AMF判断当前是否属于这种场景，若属于，则执行步骤S26。否则，则不再重新获取。
步骤S26，VPLMN AMF向HPLMN UDM请求获取EXT-SOR相关的信息。
在本申请实施例的另一个可选实施方式中，对于网络侧设备而言，在具体应用场景中还可以是通过签约信息来判断终端是否支持EXT-SOR能力，具体过程如下：
步骤S31，收到注册请求消息后，VPLMN AMF根据该UE的签约信息判断UE是否支持EXT-SOR能力；
若该VPLMN AMF中没有该UE的签约信息，则先从HPLLMN UDM获 取该UE的签约信息；若UE不支持EXT-SOR功能，则停止EXT-SOR相关行为，否则，执行步骤S32；
步骤S32，AMF决定怎样获取EXT-SOR相关的信息；
需要说明的是，步骤S32的具体过程与上述步骤S23到步骤S26相当。
需要说明的是，在通知消息中通过5GMM(5G System Mobility Management，5G系统移动性管理)capability(能力)中用于向所述网络侧设备指示所述终端支持EXT-SOR能力；在具体应用场景中，该5GMM capability如表7中的IEI为10的IE所示：

可选地，本申请实施例中的通知消息包括以下至少一项：注册请求消息、上行非传输层传输消息、协议数据单元会话消息。
可选地，在本申请实施例中，对于上述方式1)中步骤12中涉及到的根据第一信息确定当前执行的业务中是否存在目标业务的方式包括以下之一：
(1)终端根据第一信息判断终端当前执行的业务中是否存在目标业务；
(2)终端根据第一信息，和/或终端保存的签约信息，和/或终端与网络侧设备约定的目标业务，和/或终端自定义的目标业务判断当前执行的业务中是否存在目标业务。
也就是说，终端可以只根据第一信息判断当亲执行的业务中是否存在目标业务，可以进一步结合其他方式来确定，如终端与网络侧设备约定的目标业务等。
本申请实施例的可选实施方式中，对于本申请实施例中的步骤S204中涉及到的终端释放终端当前执行的业务的方式，进一步可以包括：
步骤S204-11，终端根据第一信息的指示立刻释放终端当前执行的业务；或，
步骤S204-12，根据第一信息的指示在预设时间段后释放终端当前执行的业务。
其中，对于步骤S204-12进一步可以是包括：终端根据第一信息的指示启动定时器，在定时器超时的情况下释放终端当前执行的业务。
通过上述步骤S204-11和步骤S204-12，终端可以立刻释放终端当前执行的业务也可以通过定时器来确定一段时间后再释放。
在本申请实施例的可选实施方式中，本申请实施例的方法步骤还可以进一步包括：
步骤S208，终端在定时器超时之前，接收网络侧设备发送的与EXT-SOR对应的第二信息，其中，第二信息为第一信息更新后的信息；
步骤S210，终端停止运行定时器并使用第二信息覆盖第一信息，以及根据第二信息确定终端当前执行的业务中是否存在目标业务；或，终端丢弃第 二信息，并在定时器超时的情况下根据第一信息释放终端当前执行的业务。
通过上述步骤S208和步骤S210可知，网络侧设备可以持续向终端发送与EXT-SOR对应的信息，至于终端在接收到多个与EXT-SOR对应的信息后，是否需要用后接收到的信息来覆盖前面的信息，由终端自行确定。因为后接收到的与EXT-SOR对应的信息所指示的目标业务可能不尽相同。
对于上述方式2)中涉及到的终端自主确定当前执行的业务中是否存在目标业务的方式，进一步可以包括：终端根据终端保存的签约信息，和/或终端与网络侧设备约定的目标业务，和/或终端自定义的目标业务自主确定当前执行的业务中是否存在目标业务。
基于上述方式2)，对于终端释放终端当前执行的业务的方式，可以进一步包括：终端确定立刻释放终端当前执行的业务；或，终端确定在自定义的预设时间段后释放终端当前执行的业务。
基于上述方式2)，在预设时间段后释放终端当前执行的业务的方式进一步可以包括：终端确定启动定时器，并在定时器超时的情况下释放终端当前执行的业务。
在本申请实施例的可选实施方式中，本申请实施例的方法步骤还可以进一步包括：
步骤S212，在当前执行的业务中存在目标业务的情况下，确定目标业务是否服务结束；
步骤S214，在目标业务服务结束的情况下，确定当前执行的业务中不存在目标业务。
通过上述步骤S212和步骤S214可知，如果当前执行的业务中存在目标业务的情况下，则需要在确定目标业务服务结束后，才会确定当前执行的业务中不存在目标业务，例如，如果目标业务为高优先级的业务，则当前执行的业务中存在高优先级的业务的情况下，说明终端当前有较为重要的业务需要执行，不能进行网络的转移，只有等当前执行的高优先级业务服务结束之后，说明较为重要的业务服务结束，当前执行的业务不是重要业务，则可以进行网络转移。
基于上述方式1)，本申请实施例的方法步骤还可以包括：
步骤S216，终端确定网络侧设备中的拜访公用陆地移动网VPLMN是否变更；
步骤S218，终端在VPLMN变更的情况下，删除第一信息或根据第一信息确定当前执行的业务中是否存在目标业务。
通过上述步骤S216和步骤S218可知，如果VPLMN变更，终端可以删除第一信息也可以继续根据第一信息确定当前执行的业务中是否存在目标业务，具体采用哪种方式，可以根据实际情况进行确定。
基于上述方式1)，在接收网络侧设备发送的第一信息之后，本申请实施例的方法还可以包括：
步骤S220，对第一信息进行安全性检测；其中，安全性检测包括指完整性检查和/或解密检测；
步骤S222，在第一信息安全性检测通过的情况下，确定网络侧设备中的VPLMN是否变更；
步骤S224，在网络侧设备中的VPLMN未变更的情况下，向网络侧设备发送反馈信息，其中，反馈信息用于指示终端接收到第一信息。
其中，对于步骤S224中涉及到的向网络侧设备发送反馈信息的方式进一步可以包括：
步骤S224-11，对反馈信息进行加保护；其中，加保护包括指完整性保护和/或加密保护；
步骤S224-12，将加保护后的反馈信息通过注册结束消息或上行非接入层传输消息发送给网络侧设备。
通过上述步骤S220至步骤S224，对于终端而言需要对接收到的第一信息进行安全性检测，因为网络侧设备发送的第一信息有可能是安全性较低的信息，即有可能根据安全性较低信息进行网络转移的误操作。同样地，对于终端侧而言，也需要将向网络侧设备发送的反馈信息进行加保护，以确保反馈信息的安全性。
需要说明是，该保护所使用的密钥在UE和网络之间的鉴权过程中产生，可以在安全过程中确认；保护可以采用KDF算法，例如通过KDF算法生成校验和。
在本申请实施例的具体应用场景中，在所述反馈信息中通过SOR header-new或EXT-SOR header-new指示所述终端接收到所述第一信息；其中，SOR header-new如表9所示；

在本申请实施例的可选实施方式中，在接收第一信息之后，本申请实施例中的方法步骤还可以包括：
步骤S226，终端保存第一信息到用户业务识别模块USIM或移动设备ME中。
在本申请实施例中的另一个可选实施方式中，本申请实施例的方法步骤还可以包括：
步骤S228，终端通过AT接口与用户交互第一信息。
其中，终端通过AT接口与用户交互第一信息的方式，在具体应用场景中可以是：
(1)终端可以通过AT接口与USER交互EXT-SOR相关的信息；也就是说，用户可以通过AT接口向UE查询EXT-SOR相关的信息；也可以通过AT接口设定UE是否主动上报EXT-SOR相关的信息的变更。
(2)终端可以通过AT接口把UE收到的EXT-SOR的信息向用户展示(show)，也可以通过AT接口把UE中保存的EXT-SOR的信息向用户展示；
(3)UE可以主动向用户展示，例如每次收到网络侧设备的EXT-SOR相关的信息时都展示给用户，也可以在用户查询时，向用户反馈EXT-SOR相关的信息；其中，该EXT-SOR相关的信息也可以包含网络侧设备希望UE转移到的目标PLMN等信息。
下面对本申请实施例中整个的注册流程进行举例说明，以网络侧设备决定EXT-SOR的信息驻留在VPLMN的注册流程为例进行说明，如图3所示，该注册流程的步骤包括：
步骤S301，UE可以检查UE的EXT-SOR能力，若支持EXT-SOR能力，则在REG REQ消息中携带指示：UE支持EXT-SOR能力；若不支持，则不携带该指示；
需要说明的是，UE也可以不检查UE的EXT-SOR能力，即“UE支持EXT-SOR能力”的指示不在空口消息中发给网络侧设备，而由网络侧设备根 据网络侧设备保存的签约信息来判断；此时需要UE和HPLMN UDM中保存有该UE和网络侧设备的签约信息，例如：该UE的EXT-SOR能力，和/或该UE在某些场景下如注册过程中是否要求网络侧设备返回EXT-SOR相关的信息；
步骤S302，UE向网络侧设备发送注册请求消息；
步骤S303，网络侧设备与UE之间完成互相鉴权和密钥协商；
网络侧设备收到UE的注册请求消息后，触发鉴权和密钥协商过程。该鉴权包括网络侧设备对终端合法性的判断，和终端对网络侧设备合法性的判断；该鉴权可以用5G-AKA，或EAP-AKA'算法来完成；
在鉴权过程中，网络侧设备和终端可以协商出密钥KEY1，该密钥KEY1在接下来的EXT-SOR传输和检查时将被使用；该密钥KEY1分别保留在HPLMN和UE中；
若鉴权过程中，UE或网络侧设备发现无法确认对方身份的可信性，则停止后续的EXT-SOR过程，结束注册过程。
若鉴权过程中，UE和网络侧设备互相确认了对方身份的可靠性，并且协商出了密钥，并确定后续使用该密钥，则继续104；
步骤S304，VPLMN AMF判断是否需要向HPLMN UDM获取该UE的EXT-SOR相关的信息
此外，判断过程还可以包括：
VPLMN AMF可以根据运营商的配置来协助判断；
若需要向HPLMN UDM获取该UE的EXT-SOR相关的信息,则执行105；
若不需要向HPLMN UDM获取该UE的EXT-SOR相关的信息，则按现有注册过程执行；
步骤S305，VPLMN AMF向HPLMN UDM请求该UE的EXT-SOR相关的信息，如签约信息；或，VPLMN AMF向HPLMN UDM提供相关信息，包括：UE ID(终端的身份标识)，请求EXT-SOR相关的信息的指示，UE当前的位置信息，例如地理位置，PLMN ID(归属公用陆地移动网络的标识)，TA，CELL等；
可以使用接口Nudm_SDM_Get向HPLMN UDM请求该UE的EXT-SOR 相关的信息；
步骤S306，HPLMN UDM准备EXT-SOR相关的信息；
其中，HPLMN UDM准备EXT-SOR相关的信息；
(1)HPLMN UDM经判断后决定对该UE执行EXT-SOR功能；该判断可以基于该UE的签约信息，也可以基于HPLMN的配置信息，当前负载等；
HPLMN UDM可以判断决定是自己独立提供该UE的EXT-SOR相关的信息，还是通过网络侧设备功能EXT-SOR-AF来获取；其中，该判断可以基于HPLMN的策略等，例如HPLMN是否有调用EXT-SOR-AF的策略(policy)；该判断也可以基于当前的配置，例如HPLMN当面有没有配置EXT-SOR-AF；
若HPLMN UDM通过EXT-SOR-AF来获取，则进入步骤S307；若HPLMN UDM自己决定该UE的EXT-SOR相关的信息，则进入步骤S310；
(2)若HPLMN UDM决定暂时不对该UE执行该EXT-SOR功能，例如：若HPLMN暂时自己无法计算出EXT-SOR相关的信息，暂时也无法从EXT-SOR-AF获取EXT-SOR相关的信息，则通过某种方式通知UE，指示HPLMN不要求UE执行EXT-SOR功能。该方式可以包括：1)可以不给UE返回EXT-SOR相关的信息，2)或返回指示“HPLMN不要求UE执行EXT-SOR功能”的信息；当HPLMN UDM在注册后希望通知UE更新EXT-SOR相关的信息时，可以通过EXT-SOR更新过程来处理。
步骤S307，HPLMN UDM向EXT-SOR-AF请求EXT-SOR相关的信息；
其中，HPLMN UDM向EXT-SOR-AF请求EXT-SOR相关的信息时可以提供：UE ID，请求EXT-SOR相关的信息的指示，携带UE当前的位置信息，例如地理位置，VPLMN ID，TA，CELL等；
步骤S308，EXT-SOR-AF为HPLMN UDM准备EXT-SOR相关的信息；
其中，EXT-SOR-AF为HPLMN UDM准备的该EXT-SOR相关的信息可以是明文，也可以是一种经过保护的数据包1，该经过保护的数据包1只有通过某些网络侧设备可以信赖的组件才能解析，例如USIM，或ME中保存的某加解密程序；
步骤S309，EXT-SOR-AF把EXT-SOR相关的信息发给HPLMN UDM；
步骤S310，HPLMN UDM决定对EXT-SOR相关的信息进行保护；
其中，该保护的一个目的是为了避免VPLMN对其进行篡改；一旦VPLMN篡改，UE在进行解保护时能识别出来该篡改。
该决定可以经过判断后做的决定，例如，当前UE所在的PLMN是VPLMN，或者某个不可信的网络侧设备或区域；该EXT-SOR相关的信息可以是明文的EXT-SOR相关的信息，也可以是经过保护的EXT-SOR相关的信息，如数据包1；
步骤S311，HPLMN UDM把EXT-SOR相关的信息发给负责对该数据进行保护的功能单元，例如AUSF；
步骤S312，认证服务器功能(Authorization Server Function，AUSF)对收到的EXT-SOR进行保护；
其中，保护算法将使用步骤S303中协商得到的密钥；
步骤S313，AUSF把保护后的EXT-SOR相关的信息发给HPLMN UDM；
步骤S314，HPLMN UDM把保护后的EXT-SOR相关的信息发给VPLMN AMF；
步骤S315，VPLMN AMF把保护后的EXT-SOR相关的信息转发给UE；
其中，VPLMN AMF把保护后的EXT-SOR相关的信息放进注册成功消息中，即REGISTRATION ACCEPT消息中；
步骤S316，UE对该保护后的EXT-SOR相关的信息进行处理；
其中，UE收到REGISTRATION ACCEPT消息后，对该保护后的EXT-SOR相关的信息进行处理；
步骤S317，UE反馈REGISTRATION COMPLETE；
其中，若UE检查发现VPLMN没有篡改或丢弃保护后的EXT-SOR相关的信息，则UE向HPLMN反馈收到了EXT-SOR相关的信息，该反馈信息可以包含在REGISTRATION COMPLETE中；
步骤S318，VPLMN AMF判断UE发来的消息中是否有该确认收到了EXT-SOR对应的信息；
其中，VPLMN AMF收到后，若发现REGISTRATION COMPLETE消息中有EXT-SOR的确认信息，则决定把该确认信息转发给HPLMN UDM；
步骤S319，VPLMN AMF把该确认信息转发给HPLMN UDM；
步骤S320，HPLMN UDM检查EXT-SOR的确认信息；
步骤S321，HPLMN UDM给EXT-SOR-AF转发此确认信息；
其中，若EXT-SOR-AF要求UE确认收到了EXT-SOR相关的信息，则HPLMN UDM给EXT-SOR-AF转发此确认信息；
步骤S322，EXT-SOR-AF对此EXT-SOR确认信息进行check；
其中，若成功，流程结束；若失败，EXT-SOR-AF可以重新发送EXT-SOR相关的信息；在达到重发次数要求后，可以认为该VPLMN不可靠，要求UE离开当前VPLMN，例如从当前VPLMN中的DE-REGISTRATION注册。
需要说明的是，网络侧设备决定EXT-SOR的信息还可以驻留在HPLMN，当UE在HPLMN驻留时，由于HPLMN是可信的，此时HPLMN给UE指示EXT-SOR相关的信息时，可以采用保护的形式，即与UE驻留在VPLMN时采用相同的方式获取EXT-SOR相关的信息；此时流程同CAMP(驻留)在VPLMN的注册流程。即也可以采用无保护的形式，无保护的形式，指HPLMN UDM采用明文的形式把EXT-SOR相关的信息发给HPLMN AMF。然后HPLMN AMF再在空口NAS消息中发给UE。HPLMN AMF将根据现有协议要求决定是否对该NAS消息进行安全保护，如加密和加完整性保护。如图4所示，其注册流程包括：
步骤S401，UE驻留在HPLMN时，发起注册，完成鉴权和安全；
步骤S402，AMF判断是否向UDM请求EXT-SOR相关的信息；
需要说明的是，步骤S403至S407与步骤S305至步骤S309是相同的；
步骤S408，UDM确定UE当前在HPLMN，决定不对EXT-SOR相关的信息进行保护；
步骤S409，UDM把无保护的EXT-SOR相关的信息发给HPLMN AMF；
步骤S410，HPLMN AMF把无保护的EXT-SOR相关的信息放进注册成功消息中，发给UE；
UE根据自己当前在HPLMN中，判断为：可以接受无保护的EXT-SOR相关的信息；
其中，对EXT-SOR相关的信息的处理同步骤S504～S512；若需要给HPLMN UDM反馈收到了EXT-SOR相关的信息，则可以把该反馈信息的明 文放在注册结束消息中发给网络。
在本申请实施例的具体应用场景中，基于上述步骤S301至步骤S322，对于UE对网络发来的EXT-SOR对应的信息的处理过程，还可以包括：
步骤S501，UE收到网络发来的NAS消息；
步骤S502，UE检查该NAS消息中是否包含EXT-SOR相关的信息；若UE发现网络没有提供EXT-SOR相关的参数，则不执行EXT-SOR功能；此时，UE可以认为网络不希望UE执行此功能，也可以认为VPLMN；若包含了EXT-SOR相关的信息，执行步骤S503；
步骤S503，UE对EXT-SOR相关的信息进行security check，以判断VPLMN是否对该EXT-SOR做了篡改；
若安全检查成功，进入步骤S503-11；否则进入步骤S513；
步骤S503-11，UE检查UE当前所处的PLMN是否符合条件的PLMN。
若当前所处的PLMN是符合条件的PLMN，例如，不是HPLMM，EHPLMN，User Controlled PLMN Selector with Access Technology，进入S503-13，检查选网模式的条件；
若当前所处的PLMN非符合条件的PLMN，例如，是HPLMM或EHPLMN或User Controlled PLMN Selector with Access Technology，进入步骤S503-12；
步骤S503-12，UE保存收到的EXT-SOR相关的信息；
其中，若当前的PLMN发生变更，即从非符合条件的PLMN进入其他的非符合条件的PLMN，EXT-SOR相关的信息可以继续有效，也可以被认为无效；
若当前的PLMN发生变更，即从非符合条件的PLMN进入符合条件的PLMN，EXT-SOR相关的信息可以继续有效，也可以删除；
步骤S503-13，UE检查UE当前的选网模式是否自动选网模式，当前若处于自动选网模式，则进入步骤S504；若处于手动选网模式，则保存收到EXT-SOR相关的信息，暂不执行；
若UE从手动选网模式进入自动选网模式，需要再次进入步骤S503-11；
并可以进一步检查：当前自动选网模式下的VPLMN是否是收到当前保存的EXT-SOR的那个VPLMN；并根据该检查结果进一步决定UE的后续行 为1。该UE的后续行为1可以包括：
1)若当前的VPLMN是接收当前保存的EXT-SOR的那个VPLMN，那么认为当前保存的EXT-SOR继续有效；
2)若当前的VPLMN不再是接收当前保存的EXT-SOR的那个VPLMN，那么认为当前保存的EXT-SOR继续有效；
3)若当前的VPLMN不再是接收当前保存的EXT-SOR的那个VPLMN，那么认为当前保存的EXT-SOR失效；
步骤S504，UE检查该EXT-SOR是否需要发给USIM或某专用程序进行解析，若需要，执行步骤S505；否则，把EXT-SOR解保护后的相关信息写进ME，然后执行步骤S506；
其中，进入S504前的几个条件检查：UE处于VPLMN，UE处于自动选网模式，EXT-SOR的安全检查，顺序不做限制，同时满足这几个条件即可。
步骤S505，USIM等专用程序解析EXT-SOR相关的信息，把解析后的EXT-SOR相关的信息发给UE，然后执行步骤S506；
步骤S506，UE使用该参数检查，UE当前是否有属于high priority的正在执行的业务；若有执行步骤S507，否则执行步骤S507；
其中，UE还可以补充使用UE自己定义的标准来检查是否有高优先级业务，例如UE认为某个正在执行的业务是高优先级业务，该业务可以不在网络认定的高优先级业务的范围内；
该UE自己定义的标准可以是用户自定义的，也可以是UE事先定义的；其中，若是用户自定义的，则用户可以对UE中保存的该EXT-SOR相关参数进行查询，设置，修改，删除操作；UE也可以在此参数发生变更时主动上报给用户；用户对UE中该EXT-SOR相关参数的操作可以时AT命令接口，也可以是API接口，或其他消息接口；
步骤S507，UE保存该EXT-SOR相关的信息。若UE当前已保存有EXT-SOR相关的信息，则覆盖原有EXT-SOR相关的信息；UE保存该EXT-SOR相关的信息时，可以保存其对应的当前的VPLMN的信息，如VPLMN ID；指示该EXT-SOR相关的信息是在该VPLMN下收到的；
步骤S508，UE可以等high priority on going业务结束后，再继续应用UE 保存的EXT-SOR相关的信息，无论UE所处的PLMN是否发生变更；
UE若发现高优先级业务执行过程发生PLMN变更，可以认为在前一个PLMN下收到EXT-SOR相关的信息继续有效；也可以失效；
步骤S509，UE当前是否有不属于高优先级的正在执行的业务。若有，进入S510，若没有，UE释放连接，进入IDLE态，执行步骤S512；
步骤S510，UE计算停止当前业务所需的时间，确定定时器TIMER1的时长；该时长可以设置为缺省值，也可以由UE根据实现决定(based on UE implementation)，也可以与网络协商，也可以网络在空口消息中给以指示信息，UE根据该指示信息进一步确定定时器TIMER1的时长；也可以限定一个最大值，时长不能大于这个最大值；
若当前定时器没有正在运行的话，启动定时器TIMER1；
若定时器TIMER运行期间，若发生当前的服务PLMN变更，则可以：认为当前存储的EXT-SOR相关的信息无效；或认为当前存储的EXT-SOR相关的信息仍然有效，然后根据步骤S503-11中的原则进行判断；
步骤S511，该定时器超时后，UE检查并满足上述所有条件后，释放当前业务，并释放NAS信令连接，进入IDLE态，执行步骤S512；若不满足，则继续本步骤。
其中，所述“满足上述所有条件”是指满足：EXT-SOR成功通过了安全检查；当前PLMN为User Controlled PLMN Selector with Access Technology的VPLMN；无高优先级业务；自动选网模式；定时器时长满足了要求；
对于该步骤S511中释放当前业务，包括以下场景：
场景1：如果终端当前执行的业务中存在高优先级业务，需要确定高优先级业务是否服务结束，如优先级业务降级或高优先级业务停止，则可以在“满足上述所有条件”后，对当前终端的业务进行释放。
场景2：如果当前终端只有低优先级业务，则在“满足上述所有条件”后，对当前终端的业务进行释放。
场景3：如果当前终端只有低优先级业务，则在“满足上述所有条件”中的定时器运行期间，终端停止了该低优先级业务，则也可以进行业务的释放。
场景4：如果当前终端只有低优先级业务，如果在终端执行低优先级业务 期间进入不符合PLMN，则终端停止定时器并接入步骤S503。
步骤S512，UE进行选网；其中，选网的方式可以是：排序选网，或选择到网络指定的目标网络；
步骤S513，若安全性检测失败，则确定当前VPLMN网络篡改了EXT-SOR相关的信息，也可以确定当前的VPLMN的可信度降低，UE将当前VPLMN网络设置为最低优先级；
UE可以立刻释放连接，并搜索其他网络；若没有其他可用的网络，再在当前网络上驻留注册；
UE发现VPLMN篡改了EXT-SOR相关的信息后，可用将该事件报告给用户，也可以不告诉用户。
上述图2是终端侧对本申请进行说明的，下述将从网络侧对本申请中的网络的转移方法进行说明，图5是本申请实施例的网络的转移方法流程图二，如图5所示，该方法的步骤包括：
步骤S602，网络侧设备生成与EXT-SOR对应的第一信息；
步骤S604，网络侧设备向终端发送第一信息；其中，第一信息指示具有目标信息的业务为目标业务。

在本申请实施例的可选实施方式中，对于步骤S502中涉及到的网络侧设备生成第一信息的方式进一步可以包括：网络侧设备中的归属地公用陆地移动网络统一数据管理HPLMN UDM网元生成第一信息。
在本申请实施例的可选实施方式中，对于步骤S604中涉及到的网络侧设备向终端发送第一信息进一步可以包括：
步骤S604-11，网络侧设备中的HPLMN UDM网元向网络侧设备中的AMF网元发送第一信息；
步骤S604-12，网络侧设备中的AMF网元向终端透传第一信息。
可选地，网络侧设备中的AMF网元通过以下至少之一向终端透传第一 信息：SOR的透传容器、EXT-SOR的透传容器。其中，EXT-SOR的透传容器包括以下至少一项：EXT-SOR信息1、EXT-SOR信息2、EXT-SOR的安全信息。
可选地，网络侧设备中的HPLMN UDM网元向网络侧设备中的AMF网元发送第一信息之前，方法还包括：网络侧设备中的HPLMN UDM网元向网络侧设备中的鉴权服务器功能AUSF网元对第一信息进行加保护。
在本申请实施例的可选实施方式中，在所述网络侧设备向终端发送所述第一信息之后，所述方法还包括：所述网络侧设备向终端发送与EXT-SOR对应的第二信息。
对于网络侧设备需要更新与EXT-SOR对应的信息的方式，在本申请实施例的具体应用场景中，如图6所示，该更新的过程包括：
步骤S701，UE在VPLMN中完成注册；
步骤S702，HPLMN判断EXT-SOR相关的信息需要更新；
步骤S703，HPLMN准备EXT-SOR相关的信息；若HPLMN UDM通过EXT-SOR-AF来获取，则进入步骤S703；
步骤S704，HPLMN UDM向SOR-AF请求EXT-SOR信息；
步骤S705，SOR-AF决定EXT-SOR信息；
步骤S706，SOR-AF反馈EXT-SOR信息；
步骤S707，HPLMN UDM对EXT-SOR信息进行保护；
步骤S708，HPLMN UDM向AUSF发送EXT-SOR信息；
步骤S709，AUSF对EXT-SOR信息进行保护；
步骤S710，AUSF向HPLMN UDM发送保护后的EXT-SOR信息；
可见，上述步骤S704～S710与图3中的步骤S307～S313是相同的；
步骤S711，HPLMN UDM把保护后的更新的EXT-SOR相关的信息发给VPLMN AMF；
步骤S712，VPLMN AMF把收到的保护后的更新的EXT-SOR相关的信息通过NAS消息透传给UE。例如通过MM消息，通过DL NAS TRANSPORT(下行非接入层传输)消息。VPLMN AMF不能更改该保护后的更新的EXT-SOR相关的信息；
步骤S713，UE收到保护后的更新的EXT-SOR相关的信息后，先对该信息进行安全检查，如完整性检查；
步骤S714，若需要向网络反馈UE成功收到了该更新的EXT-SOR相关的信息，则可以把反馈信息进行保护，然后在上行非接入层(Non Access Stratum，NAS)消息中发给网络，例如UL NAS TRANSPORT(上行非接入层传输)消息；
步骤S715，VPLMN AFM判断是否收到了EXT-SOR信息；
步骤S716，HPLMN AFM向HPLMN UDM反馈确认消息；
步骤S717，HPLMN UDM检查确认消息；
步骤S718，HPLMN UDM向SOR-AF转发确认消息。
需要说明的是，该流程中的S715～S718与图3中的步骤S318～S321是相同的。
此外，还可以是网络决定EXT-SOR相关的信息驻留在HPLMN的更新。即当UE在HPLMN驻留和注册后，HPLMN是可信的，此时HPLMN给UE指示EXT-SOR相关的信息时，可以采用保护的形式，即与UE驻留在VPLMN时采用相同的方式更新EXT-SOR相关的信息；此时流程同驻留在VPLMN的注册流程；也可以通过传输无保护的EXT-SOR相关的信息，通知UE。UE收到后，将EXT-SOR相关的信息保存。该参数将在UE驻留到符合条件的VPLMN时被使用。
需要说明的是，本申请实施例提供的网络的转移方法，执行主体可以为网络的转移装置，或者，该网络的转移装置中的用于执行网络的转移方法的控制模块。本申请实施例中以网络的转移装置执行网络的转移方法为例，说明本申请实施例提供的网络的转移装置。
本申请实施例提供了一种网络的转移装置，图7是本申请实施例的网络的转移装置结构示意图一，如图7所示，该装置包括：
获取模块72，用于获取终端当前执行的业务；
释放模块74，用于在终端当前执行的业务中不存在目标业务的情况下，释放终端当前执行的业务；
执行模块76，用于在释放终端当前执行的业务后，执行对终端的网络转 移。
可选地，本申请实施例的装置还可以包括：
