具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
需要说明的是，本申请实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。同时描述的“第一”、“第二”描述的对象可以相同，也可以不同。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信(5th-Generation，5G)系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。
本申请实施例对应用的频谱并不限定。例如，本申请实施例可以应用于授权频谱，也可以应用于免授权频谱。
本申请实施例结合网络设备和终端设备描述了各个实施例，其中：终端设备也可以称为用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置等。终端设备可以是WLAN中的站点(STAION，ST)，可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信系统，例如，NR网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备等。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
网络设备可以是用于与移动设备通信的设备，网络设备可以是WLAN中的接入点(Access Point，AP)，GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB，NB)，还可以是LTE中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及NR网络中的网络设备(gNB)或者未来演进的PLMN网络中的网络设备等。

图1示例性地示出了卫星网络中，卫星网络覆盖范围的示意图。在卫星网络中，一个卫星可以覆盖多个国家；如图1中卫星1覆盖国家1和国家2，卫星2覆盖国家1。
应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
应理解，在本申请的实施例中提到的“指示”可以是直接指示，也可以是间接指示，还可以是表示具有关联关系。举例说明，A指示B，可以表示A直接指示B，例如B可以通过A获取；也可以表示A间接指示B，例如A指示C，B可以通过C获取；还可以表示A和B之间具有关联关系。
在本申请实施例的描述中，术语“对应”可表示两者之间具有直接对应或间接对应的关系，也可以表示两者之间具有关联关系，也可以是指示与被指示、配置与被配置等关系。
为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明， 以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
以图1所示的卫星覆盖范围为例。在一种场景下，当UE处于国家1时，UE处于卫星1和卫星2的覆盖范围；如果卫星1在国家1中没有地面接收站为该UE服务，则UE也就不能选择到国家1的核心网。这样，如果UE选择卫星1的PLMN，就会导致不符合UE所在国家的政策监管及合法监听要求。
在另一种场景下，如果UE在国家2时选择了卫星1所对应的PLMN为其服务；当UE从国家2移动至国家1时，由于UE处于卫星1和卫星2的覆盖中，并且UE目前所使用的PLMN刚好是卫星1所广播的PLMN，按照相关技术中的PLMN选择方法，UE即使移动至国家1中，也不会触发PLMN选择过程，而是仍然选择由卫星1为其服务。如果卫星1在国家1中没有地面接收站为该UE服务，同样会出现UE选择的卫星1的PLMN不符合UE所在国家的政策监管及合法监听要求的情况。
可见，相关技术中存在UE选择的卫星网络的PLMN与UE所处的位置(如国家/地区)不相符的情况。
针对上述问题，本申请实施例提出一种选择网络的方法，图2是根据本申请实施例的一种选择网络的方法200的示意性流程图，该方法可选地可以应用于图1所示的系统，但并不仅限于此。该方法包括以下内容的至少部分内容。
S210：终端设备在预设情况下，根据该终端设备的位置及优先选择列表，选择与该终端设备的位置对应的卫星网络的PLMN。
在一些实施方式中，上述预设情况可以包括：终端设备的位置发生变化。
在一些实施方式中，上述预设情况可以包括：PLMN选择定时器超时。
在一些实施方式中，上述预设情况可以包括：终端设备从网络设备接收到第一指示消息，该第一指示消息指示该终端设备进行PLMN选择。
以下举具体的实施例，详细介绍各种情况下终端设备选择卫星网络的PLMN具体示例。
实施例一：
图3是本申请实施例一的实现流程图，包括以下步骤：
步骤1，覆盖国家1及国家2的卫星无线接入网(RAN，Radio Access Network)，如卫星RAN 1进行广播；该广播消息中携带对应的PLMN标识(如PLMN ID 1)，该PLMN ID 1中包括移动国家码(MCC，Mobile Country Code)和移动网络码(MNC，Mobile Network Code)，如(MCC 1+MNC 1)。覆盖国家2的卫星RAN 2进行广播，该广播消息中携带PLMN标识(如PLMN ID 2)，该PLMN ID 2中包括(MCC 2+MNC 2)。覆盖国家1的地面蜂窝网络(TN，Terrestrial Network)中的RAN(以下简称TN-RAN)进行广播，TN-RAN的广播消息中携带PLMN标识(如PLMN ID-TN)，该PLMN ID-TN中包括(MCC-TN+MNC-TN)。UE监听上述卫星RAN 1、卫星RAN 2和TN-RAN的广播消息。
步骤2，UE根据不同时刻接收的TN-RAN的广播消息中携带的PLMN ID-TN中的MCC，判断终端设备的位置是否发生变化。例如，当UE不同时刻接收到的TN-RAN的广播消息中的MCC(即上述MCC-TN)不同时，可以获知UE所在的国家发生变化。当UE所在国家发生变化时，UE根据自身的位置信息和优先选择列表重新进行卫星网络的PLMN选择。
在一些实施方式中，上述优先选择列表配置在终端设备上。
可选地，上述优先选择列表包括不同位置对应的卫星网络的PLMN信息。
其中，上述PLMN信息可以包括MCC信息和MNC信息，其中的MCC信息可 以与位置对应。
图4A和图4B是本申请的两种优先选择列表示例的示意图，该优先选择列表预先配置在UE上，UE上可以配置其中的一种优先选择列表、或者同时配置两种优先选择列表。
如图4A所示，国家X配置的可用的卫星网络的PLMN包括PLMN a、PLMN b等，其中PLMN a、PLMN b等PLMN信息中包括的MCC信息均为MCC-X，该MCC-X与国家X的地面蜂窝网络广播的MCC一致。国家Y配置的可用的卫星网络的PLMN包括PLMN c、PLMN d等，其中PLMN c、PLMN d等PLMN信息中包括的MCC信息均为MCC-Y，该MCC-Y与国家Y的地面蜂窝网络广播的MCC一致。可见，图4A所示的优先选择列表中，卫星网络的PLMN中的MCC能够表征对应的国家。由于优先选择列表中卫星网络的PLMN中的MCC能够表征对应的国家，因此终端设备可以直接根据MCC进行选择，如选择包含与TN-RAN的广播消息中的MCC相同的MCC的PLMN。由于TN-RAN的广播消息中的MCC能够表示UE的位置，因此这种方式本质上就是在根据UE的位置及优先选择列表选择对应的卫星网络的PLMN。如果步骤1中UE监听的卫星RAN 1或卫星RAN 2的广播消息中存在与前述选择的PLMN对应的PLMN ID，则UE选择该PLMN ID对应的卫星网络为其服务。
如图4B所示，国家X配置的可用的卫星网络的PLMN包括PLMN a、PLMN b等，其中PLMN a中包括的MCC信息为MCC a，PLMN b中包括的MCC信息为MCC b，MCC a和MCC b是卫星网络使用的专门的MCC，不能够表征对应的国家。国家Y配置的可用的卫星网络的PLMN具有同样的情况。因此，在图4B所示的优先选择列表中包括国家信息，即国家X对应优先列表X，包括PLMN a、PLMN b等；国家Y对应优先列表Y，包括PLMN c、PLMN d等。由于优先选择列表中卫星网络的PLMN中的MCC不能够表征对应的国家，因此终端设备可以根据TN-RAN的广播消息中的MCC确定UE所在的位置(如国家)、或者根据上层应用的定位信息确定UE所在的位置(如国家)，并根据该位置信息查找优先选择列表，从中选择该位置信息对应的PLMN。同样地，如果步骤1中UE监听的卫星RAN 1或卫星RAN 2的广播消息中存在与前述选择的PLMN对应的PLMN ID，则UE选择该PLMN ID对应的卫星网络为其服务。
实施例二：
图5是本申请实施例二的实现流程图，包括以下步骤：
步骤1，覆盖国家1及国家2的卫星RAN 1进行广播；该广播消息中携带对应的PLMN标识(如PLMN ID 1)，该PLMN ID 1中包括(MCC 1+MNC 1)。覆盖国家2的卫星RAN 2进行广播，该广播消息中携带PLMN标识(如PLMN ID 2)，该PLMN ID 2中包括(MCC 2+MNC 2)。
步骤2，UE根据不同时刻的上层应用的定位信息，判断UE的位置是否发生变化。例如，定位软件等上层应用将UE的定位信息(如国家信息)通知UE的NAS层，如果不同时刻通知的国家信息不同，则UE可以获知自身所在的国家发生变化。当UE所在国家发生变化时，UE根据自身的位置信息和优先选择列表重新进行卫星网络的PLMN选择。
优先选择列表的配置方式及具体内容与实施例一相同，在此不再赘述。
其中，UE可以根据TN-RAN的广播消息中的MCC确定自身的位置信息；例如，UE监听覆盖UE当前所在国家的TN-RAN的广播消息，根据该广播消息携带的PLMN标识中的MCC标识，确定UE当前所在的国家。
或者，UE可以根据上层应用的定位信息确定当前所在的国家。
UE选择与当前所在位置对应的卫星网络的PLMN的方式与实施例一相同，在此不再赘述。
实施例三：
图6是本申请实施例三的实现流程图，包括以下步骤：
步骤1，覆盖国家1及国家2的卫星RAN 1进行广播；该广播消息中携带对应的PLMN标识(如PLMN ID 1)，该PLMN ID 1中包括(MCC 1+MNC 1)。覆盖国家2的卫星RAN 2进行广播，该广播消息中携带PLMN标识(如PLMN ID 2)，该PLMN ID 2中包括(MCC 2+MNC 2)。
步骤2，UE根据UE的位置信息进行PLMN选择，PLMN选择完成后，UE启动PLMN选择定时器。在本实施例中，PLMN定时器针对不同的位置配置。例如，以图4A和图4B所示的优先选择列表为例，可以在预先配置的优先选择列表中增加各个国家对应的PLMN选择定时器，如在图4A和图4B中增加国家X和国家Y对应的PLMN选择定时器。
UE在PLMN选择完成后，启动当前所在国家对应的PLMN选择定时器。当PLMN选择定时器超时时，UE根据自身的位置信息和优先选择列表重新进行卫星网络的PLMN选择。优先选择列表的具体形式及UE选择PLMN的方式与实施例一相同，在此不再赘述。
实施例四：
图7是本申请实施例四的实现流程图，包括以下步骤：
步骤1，覆盖国家1及国家2的卫星RAN 1进行广播；该广播消息中携带对应的PLMN标识(如PLMN ID 1)，该PLMN ID 1中包括(MCC 1+MNC 1)。覆盖国家2的卫星RAN 2进行广播，该广播消息中携带PLMN标识(如PLMN ID 2)，该PLMN ID 2中包括(MCC 2+MNC 2)。
步骤2，UE根据UE的位置信息进行PLMN选择，PLMN选择完成后，UE启动PLMN选择定时器。在本实施例中，PLMN定时器针对不同的PLMN配置。例如，以图4A和图4B所示的优先选择列表为例，可以在预先配置的优先选择列表中增加PLMN对应的PLMN选择定时器，如在图4A和图4B中增加PLMN a、PLMN b、PLMN c、PLMN d等PLMN标识对应的PLMN选择定时器。
UE在PLMN选择完成后，启动当前选择的PLMN对应的PLMN选择定时器。当PLMN选择定时器超时时，UE根据自身的位置信息和优先选择列表重新进行卫星网络的PLMN选择。优先选择列表的具体形式及UE选择PLMN的方式与实施例一相同，在此不再赘述。
实施例五：
图8是本申请实施例五的实现流程图，包括以下步骤：
步骤1，覆盖国家1及国家2的卫星RAN 1进行广播；该广播消息中携带对应的PLMN标识(如PLMN ID 1)，该PLMN ID 1中包括(MCC 1+MNC 1)。覆盖国家2的卫星RAN 2进行广播，该广播消息中携带PLMN标识(如PLMN ID 2)，该PLMN ID 2中包括(MCC 2+MNC 2)。
步骤2，UE根据UE的位置信息进行PLMN选择并进行接入。
步骤3，UE进行注册过程，在注册过程中，网络设备，如接入与移动性管理功 能(AMF，Access and Mobility Management Function)为UE分配新的5G全局唯一的临时UE标识(5G-GUTI，5G Globally Unique Temporary UE Identity)。
步骤4，AMF触发位置服务流程，该过程可以周期性触发。这样，AMF可以周期性地获取UE的位置信息；
步骤5；根据不同时刻获取的UE的位置信息，AMF可以判断UE的位置(如国家)是否发生变化。在AMF判断出UE所在的国家发生变化时，继续执行步骤6。
步骤6，AMF向UE发送第一指示消息，该第一指示消息指示UE进行PLMN选择。具体地，该第一指示消息可以包括非接入层(NAS，Non-Access Stratum)消息。
步骤7，UE从网络设备(如AMF)接收到第一指示消息，根据自身的位置信息和优先选择列表重新进行卫星网络的PLMN选择。在进行PLMN选择之前，UE首先进入空闲态。优先选择列表的具体形式及UE选择PLMN的方式与实施例一相同，在此不再赘述。
以上各个实施例中，是将UE的位置具体为UE所在的国家进行介绍的。在本申请其他实施例中，UE的位置还可以为地区。本申请对UE的位置的具体含义不做限制。
综上可见，本申请提出的非陆地网络(NTN，non-terrestrial network)网络中根据位置信息选择PLMN的方法，能够使UE在移动过程中及时进行PLMN选择，避免了UE仍然使用所在国家/地区之外的卫星网络。
本申请还提出一种网络选择指示方法，图9是根据本申请实施例的一种网络选择指示方法900的示意性流程图，该方法包括以下内容的至少部分内容。
