Description

网络选择方法、装置、设备及存储介质 技术领域
本申请实施例涉及通信技术领域，特别涉及一种网络选择方法、装置、设备及存储介质。
背景技术
3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)在5G NR(New Radio，新空口)系统中引入了NTN(Non Terrestrial Network，非地面通信网络)技术。
NTN一般采用卫星通信的方式向地面用户提供通信服务。相比地面蜂窝网通信系统，NTN系统具有很多独特的优点。首先，NTN系统不受用户地域的限制，由于一颗卫星即可以覆盖较大的地面，且卫星可以围绕地球做轨道运动，因此理论上地球上每一个角落都可以被NTN系统覆盖。其次，NTN系统有较大的社会价值，NTN系统在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到，从而使这些地区的人们享受到先进的语音通信和移动互联网技术，有利于缩小与发达地区的数字鸿沟，促进这些地区的发展。再次，NTN系统距离远，且通信距离增大通讯的成本没有明显增加。最后，NTN系统的稳定性高，不受自然灾害的限制。
正是由于卫星的网络覆盖较广，单个卫星可能覆盖多个区域，而其覆盖的区域中，有些区域可能没有与该卫星对应的地面接收站。当终端设备位于这些没有与该卫星对应的地面接收站的区域时，若选择该卫星的网络实现卫星通信将会违背这些区域的合法监听要求等。因此，在NTN技术中，如何进行网络选择以实现卫星通信还需要进一步地讨论和研究。

网络设备10是用于为终端设备20提供无线通信服务的设备。网络设备10与终端设备20之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。网络设备10的数量可以有多个，两个邻近的网络设备10之间也可以通过有线或者无线的方式进行通信。终端设备20可以在不同的网络设备10之间进行切换，也即与不同的网络设备10建立连接。
在一个示例中，如图2所示，以蜂窝通信网络为例，蜂窝通信网络中的网络设备10可以是基站12。基站12是一种部署在接入网中用以为终端设备20提供无线通信功能的装置。基站12可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备网络设备功能的设备的名称可能会有所不同，例如在5G NR(New Radio，新空口)系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端设备20提供无线通信功能的装置统称为网络设备。
在另一个示例中，如图3所示，以NTN网络为例，NTN网络中的网络设备10可以是卫星11。一颗卫星11可以覆盖一定范围的地面区域，为该地面区域上的终端设备20提供无线通信服务。另外，卫星11可以围绕地球做轨道运动，通过布设多个卫星11，可以实现对地球表面的不同区域的通信覆盖。
相比于地面的蜂窝通信网络，卫星通信具有很多独特的优点。首先，卫星通信不受用户地域的限制，例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域，而对于卫星通信来说，由于一颗卫星即可以覆盖较大的地面，加之卫星可以围绕地球做轨道运动，因此理论上地球上每一个角落都可以被卫星通信覆盖。其次，卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到，从而使这些地区的人们享受到先进的语音通信和移动互联网技术，有利于缩小与发达地区的数字鸿沟，促进这些地区的发展。再次，卫星通信距离远，且通信距离增大通讯的成本没有明显增加；最后，卫星通信的稳定性高，不受自然灾害的限制。
通信卫星按照轨道高度的不同分为LEO(Low-Earth Orbit，低地球轨道)卫星、MEO(Medium-Earth Orbit，中地球轨道)卫星、GEO(Geostationary Earth Orbit，地球同步轨道)卫星、HEO(High Elliptical Orbit，高椭圆轨道)卫星等等。目前阶段主要研究的是LEO和GEO。
1、LEO
低轨道卫星高度范围为500km～1500km，相应轨道周期约为1.5小时～2小时。用户间单跳通信的信号传播延迟一般小于20ms。最大卫星可视时间20分钟。信号传播距离短，链路损耗少，对用户终端的发射功率要求不高。
2、GEO
地球同步轨道卫星，轨道高度为35786km，围绕地球旋转周期为24小时。用户间单跳通信的信号传播延迟一般为250ms。
为了保证卫星的覆盖以及提升整个卫星通信系统的系统容量，卫星采用多波束覆盖地面，一颗卫星可以形成几十甚至数百个波束来覆盖地面；一个卫星波束可以覆盖直径几十至上百公里的地面区域。
需要说明的一点是，本申请实施例中涉及的终端设备20，可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端设备。
另外，在本申请实施例中，名词“网络”和“系统”通常混用，但本领域技术人员可以理解其含义。
终端设备接入网络时需要进行网络选择，以选择合适的网络实现网络通信。可选地，本申请实施例中，终端设备进行网络选择是进行PLMN选择。在一个示例中，在蜂窝通信网络中，终端设备可以根据配置的PLMN的优先级顺序来进行网络选择。
(1)归属PLMN；
(2)“User Controlled PLMN Selector with Access Technology(用户控制的PLMN选择和接入技术)”配置列表中的PLMN；
(3)“Operator Controlled PLMN Selector with Access Technology(运营商控制的PLMN选择和接入技术)”配置列表中的PLMN。
也即，终端设备优先选择归属PLMN。在终端设备位于归属PLMN的覆盖范围之外时，启动扫描定时器(Scan Timer)。可选地，终端设备周期性地扫描归属PLMN，或“User Controlled PLMN Selector with Access Technology”配置列表中的PLMN，或“Operator Controlled PLMN Selector with Access Technology”配置列表中的PLMN。
可选地，在终端设备开机，或者终端设备从无网络覆盖的区域进入有网络覆盖的区域的情况下，终端设备首先选择其存储的注册PLMN(Registered PLMN，简称RPLMN)。当终端设备无法选择到RPLMN的时候，才会选择其它PLMN。
不同于蜂窝网络通信系统，在NTN通信系统中，由于卫星的网络覆盖较广，单个卫星可能覆盖多个区域。如图4所示，卫星1覆盖国家1和国家2，卫星2覆盖国家1。从而，当终端设备位于国家1时，其处于卫星1和卫星2的网络覆盖范围中。
然而，在某些情况下，卫星的网络覆盖区域中，有些区域可能没有与该卫星对应的地面接收站。例如，如图4所示，卫星1在国家1中没有相应的地面接收站，这样终端设备将无法接入到国家1的核心网，从而终端设备选择卫星1的网络进行卫星通信将会违背国家1的合法监听要求等。此外，如图4所示，终端设备位于国家1时，处于卫星1和卫星2的网络覆盖中，假设终端设备的归属PLMN为卫星1的网络，按照蜂窝通信系统中的网络选择方法，终端设备即便位于国家1也会优先选择卫星1为其服务，由于卫星1在国家1中没有相应的地面接收站，终端设备选择卫星1的网络进行卫星通信将会违背国家1的合法监听要求等。
基于此，本申请实施例针对NTN通信系统中如何进行网络选择以实现卫星通信，提供了一种网络选择方法。通过本申请实施例提供的技术方案，终端设备位于某一区域时，选择该区域对应的可用网络，从而避免通过选择的网络无法接入该区域的核心网，确保了卫星通信的有效性和合法性。下面，通过几个方法实施例对本申请实施例的技术方案进行介绍说明。
请参考图5，其示出了本申请一个实施例提供的网络选择方法的流程图，该方法可应用于上述NTN通信系统中，该方法可以包括如下几个步骤(步骤510～530)：
步骤510，终端设备确定终端设备当前的第一位置信息。
为了实现终端设备选择其所在区域对应的可用网络，终端设备需要先确定其当前所在的区域。本申请实施例中，终端设备确定其当前的第一位置信息，该当前的第一位置信息即表示终端设备当前所在的区域。本申请实施例对当前的第一位置信息的内容不作限定，可选地，当前的第一位置信息包括终端设备当前所处的地理位置；或者，当前的第一位置信息包括终端设备当前所处的国家；或者，当前的第一位置信息包括终端设备当前所处的行政区划；或者，当前的第一位置信息包括终端设备当前所处的服务小区；或者，当前的第一位置信息包括终端设备当前所处的通信系统。
在一个示例中，当前的第一位置信息包括以下至少一项：地理位置、第一MCC(Mobile Country Code，移动国家码)；其中，第一MCC是指终端设备所处的蜂窝网络广播的MCC。也即，终端设备的当前位置信息可以包括地理位置和/或第一MCC。
地理位置可以通过定位得到，可选地，地理位置通过以下至少一种定位方式得到：网络定位方式、卫星定位方式、实时动态定位方式或精密单点定位方式。其中，网络定位方式是指基于终端设备连接的网络进行定位的方式，卫星定位方式是指基于终端获取的观测卫星信息进行定位的方式(或者也可以称为GPS(Global Positioning System，全球定位系统)定位方式)，实时动态定位方式是指基于终端获取的差分数据进行定位的方式，精密单点定位方式是指基于终端获取的精密导航电文进行定位的方式。
第一MCC是指终端设备当前所处国家的移动国家码，第一MCC可以通过终端设备所处的蜂窝网络发送给终端设备，也即，覆盖范围内包括终端设备的蜂窝网络向终端设备发送第一MCC，以使得终端设备明确其当前所处的位置。可选地，第一MCC承载在系统消息中，也即，终端设备当前所处的蜂窝网络广播第一MCC。
本申请实施例中，在终端设备位于其归属国家(即归属PLMN所对应的国家)时，终端设备可以优先选择归属PLMN。而在终端设备位于其归属国家之外的国家(即终端设备处于漫游状态)时，终端设备可以按照本申请实施例提供的网络选择方法进行网络选择。基于此，在一个示例中，上述步骤510包括：在终端设备位于终端设备的归属国家之外的国家的情况下，确定当前的第一位置信息。
由上述介绍说明可知，终端设备在开机或重新进入网络覆盖区域时，优先选择注册网络(如RPLMN)。本申请实施例中，终端设备在开机或重新进入网络覆盖区域时，若终端设备位于注册网络对应的国家，则终端设备可以优先选择注册网络；若终端设备位于注册网络对应的国家之外的国家，则终端设备可以按照本申请实施例提供的网络选择方法进行网络选择。基于此，在另一个示例中，上述步骤510包括：在终端设备开机或重新进入网络覆盖区域，且终端设备位于终端设备的注册网络对应的国家之外的国家的情况下，确定当前的第一位置信息。
步骤520，终端设备从候选网络信息集合中选择当前的第一位置信息对应的候选网络信息，候选网络信息集合包括第一位置信息和候选网络信息之间的对应关系，候选网络信息用于指示至少一个用于实现卫星通信的PLMN。
终端设备在确定了当前的第一位置信息之后，可以进一步获取候选网络信息集合，并从候选网络信息集合中选择与当前的第一位置信息对应的候选网络信息，以便于后续使用该候选网络信息进行网络选择。其中，候选网络信息集合包括第一位置信息和候选网络信息之间的对应关系，也即，在候选网络信息集合中配置了至少一个第一位置信息，每一个第一位置信息均有其对应的候选网络信息。有关候选网络信息集合的具体配置方式请参见下述实施例，此处不多赘述。
本申请实施例对候选网络信息集合的配置方式不作限定，可选地，候选网络信息集合承载在终端设备的SIM(Subscriber Identity Module，用户识别模块)卡中，例如，候选网络信 息集合由运营商配置并写入SIM卡中，终端设备使用该运营商生产的SIM卡，即可获取候选网络信息集合；或者，候选网络信息集合由网络设备向终端设备发送，例如，网络设备预配置有候选网络信息集合，然后通过NAS(Non-Access Stratum，非接入层)消息等发送给终端设备，终端设备接收到该NAS消息即可获取候选网络信息集合。基于此，在一个示例中，上述步骤520之前，还包括：网络设备向终端设备发送候选网络信息集合。可选地，该候选网络信息集合承载在NAS信令中。
候选网络信息用于指示至少一个用于实现卫星通信的PLMN，其可以作为后续终端设备选择PLMN的依据。在一个示例中，候选网络信息包括第二位置信息和移动网络信息。可选地，第二位置信息包括第二MCC，第二MCC是指卫星网络能够广播的MCC；移动网络信息包括MNC(Mobile Network Code，移动网络码)。可选地，在第二位置信息为第二MCC、移动网络信息为MNC的情况下，候选PLMN的标识(Identifier，ID)可以采用MCC和MNC之和来表示，也即，PLMN ID：MCC+MNC。
步骤530，终端设备根据当前的第一位置信息对应的候选网络信息进行网络选择。
当前的第一位置信息对应的候选网络信息可以指示至少一个PLMN，该至少一个PLMN即为终端设备当前所在区域对应的可用PLMN。终端设备在从候选网络信息集合中选择了当前的第一位置信息对应的候选网络信息之后，即可按照当前的第一位置信息对应的候选网络信息指示的至少一个PLMN进行网络选择，也即，从该至少一个PLMN中选择进行卫星通信时使用的PLMN。有关终端设备进行网络选择的其它介绍说明，请参见下述方法实施例，此处不多赘述。
综上所述，本申请实施例提供的技术方案，通过终端设备确定当前所处的位置，然后确定当前所处的位置对应的可用PLMN，再从当前所处的位置对应的可用PLMN中选择进行卫星通信时使用的PLMN，使得终端设备依据其当前所处的位置灵活确定可用PLMN进行网络选择。并且，本申请实施例为终端设备配置了用于指示可用PLMN的候选网络信息集合，该候选网络信息集合包括位置和指示可用PLMN的候选网络信息之间的对应关系，相比于为终端设备配置单一固定的PLMN列表无法满足终端设备针对不同位置的合法监听要求等灵活进行网络选择，本申请实施例充分考虑了不同位置的合法监听要求等差异，实现了根据位置的不同差异化地配置可用PLMN，避免终端设备由于选择的PLMN不满足终端设备所处位置的合法监听要求等而无法实现卫星通信，提升了终端设备选择实现卫星通信的PLMN的准确性和有效性。
下面针对候选网络信息集合的具体配置方式进行介绍说明。
可选地，候选网络信息集合包括n个子集合，n为正整数。
本申请实施例中，候选网络信息集合可以按照第一位置信息的不同划分为多个子集合，假设有n个第一位置信息，那么候选网络信息集合也包括n个子集合，n为正整数。例如，第一位置信息包括蜂窝通信网络广播的MCC(第一MCC)，不同的第一MCC表征不同的国家，若有n个第一MCC，候选网络信息集合则包括n个子集合，每个子集合与一个第一MCC对应。
在一个示例中，在第一位置信息与第二位置信息一致的情况下，n个子集合中的第i个子集合包括：第i个第一位置信息和至少一个移动网络信息之间的对应关系，i为小于或等于n的正整数。
可选地，第一位置信息与第二位置信息一致包括第一位置信息的含义和第二位置信息的含义一致。例如，第一位置信息包括第一MCC，该第一MCC表征不同的国家；第二位置信息包括第二MCC，该第二MCC是指卫星网络广播的MCC，若第二MCC也能够表征不同的国家，则第一MCC和第二MCC一致，也即，第一位置信息与第二位置信息一致。
第一位置信息和第二位置信息一致的情况下，在配置候选网络信息集合时可以直接使用第一位置信息和移动网络信息来进行配置。针对候选网络信息集合的n个子集合中的第i个 子集合，该第i个子集合与第i个第一位置信息对应，则该第i个子集合中包括第i个第一位置信息和至少一个移动网络信息之间的对应关系。
例如，假设第一位置信息包括第一MCC，移动网络信息包括MNC，如图6(a)所示，候选网络信息集合包括n个子集合，每个子集合与一个第一MCC对应，也即，每个子集合与一个国家对应，并且，每个子集合指示一个国家对应的可用PLMN。其中，针对国家X，该国家X对应的子集合中包括MCC-X与至少一个MNC之间的对应关系，并且，MCC-X与不同的MNC组合在一起指示不同的PLMN；针对国家Y，该国家Y对应的子集合中包括MCC-Y与至少一个MNC之间的对应关系，并且，MCC-Y与不同的MNC组合在一起指示不同的PLMN。结合图6(a)，国家X和国家Y分别对应的可用PLMN的配置方式如下所示：
国家X对应的可用PLMN：PLMN a：MCC-X+MNC a至PLMN b：MCC-X+MNC b；
国家Y对应的可用PLMN：PLMN c：MCC-Y+MNC c至PLMN d：MCC-Y+MNC d。
在另一个示例中，在第一位置信息与第二位置信息不一致的情况下，n个子集合中的第i个子集合包括：第i个第一位置信息和至少一个第二位置信息以及至少一个移动网络信息之间的对应关系，i为小于或等于n的正整数。
可选地，第一位置信息与第二位置信息不一致包括第一位置信息的含义和第二位置信息的含义不一致。例如，第一位置信息包括第一MCC，该第一MCC表征不同的国家；第二位置信息包括第二MCC，该第二MCC是指卫星网络广播的MCC，若第二MCC不能够表征不同的国家，例如，第二MCC为卫星网络广播的专用MCC，则第一MCC和第二MCC不一致，也即，第一位置信息和第二位置信息不一致。
第一位置信息和第二位置信息不一致的情况下，在配置候选网络信息集合时不能够直接使用第一位置信息和移动网络信息来进行配置，还需要考虑到第二位置信息。针对候选网络信息集合的n个子集合中的第i个子集合，该第i个子集合与第i个第一位置信息对应，则该第i个子集合中包括第i个第一位置信息和至少一个第二位置信息以及至少一个移动网络信息之间的对应关系。
例如，假设第一位置信息包括第一MCC，第二位置信息包括第二MCC，移动网络信息包括MNC，如图6(b)所示，候选网络信息集合包括n个子集合，每个子集合与一个第一MCC对应，也即，每个子集合与一个国家对应，并且，每个子集合指示一个国家对应的可用PLMN。其中，针对国家X，该国家X对应的子集合中包括MCC-X与至少一个第二MCC以及至少一个MNC之间的对应关系，并且，MCC-X与不同的第二MCC以及MNC组合在一起指示不同的PLMN；针对国家Y，该国家Y对应的子集合中包括MCC-Y与至少一个第二MCC以及至少一个MNC之间的对应关系，并且，MCC-Y与不同的第二MCC以及MNC组合在一起指示不同的PLMN。结合图6(b)，国家X和国家Y分别对应的可用PLMN的配置方式如下所示：
国家X对应的可用PLMN：PLMN a：MCC a+MNC a至PLMN b：MCC b+MNC b；
国家Y对应的可用PLMN：PLMN c：MCC c+MNC c至PLMN d：MCC d+MNC d。
需要说明的一点是，在实际应用中，既可以只为终端设备配置第一位置信息和第二位置信息一致时的候选网络信息集合；也可以只为终端设备配置第一位置信息和第二位置信息不一致时的候选网络信息集合；还可以既为终端设备配置第一位置信息和第二位置信息一致时的候选网络信息集合，也为终端设备配置第一位置信息和第二位置信息不一致时的候选网络信息集合。具体采用哪一种配置方式可以集合终端设备的能力、卫星网络的广播方式等因素来确定，本申请实施例对此不作限定。
综上所述，本申请实施例提供的技术方案，通过按照不同的位置来配置指示可用PLMN的候选网络信息集合，该候选网络信息集合中的每一个子集合与一个位置对应，并指示该位置对应的可用PLMN，从而便于后续终端设备根据所处的位置快速查找到该位置对应的可用PLMN。并且，本申请实施例中，按照蜂窝网络广播的位置和卫星网络广播的位置是否一致，提供了不同的配置方式，从而能够适配卫星网络的不同广播方式，提升了候选网络信息集合 的兼容性。
下面针对终端设备进行网络选择的过程进行介绍说明。
可选地，当前的第一位置信息对应的候选网络信息用于指示m个PLMN，m为正整数。
本申请实施例中，当前的第一位置信息对应的候选网络信息用于指示m个PLMN，m为正整数，该m个PLMN即为当前的第一位置信息对应的可用PLMN。
在一个示例中，如图7所示，上述步骤530包括如下几个子步骤：
步骤532，终端设备接收至少一个卫星网络的广播信息，广播信息用于指示网络覆盖范围中包括终端设备的PLMN。
至少一个卫星网络可以在其网络覆盖范围内进行广播，该广播信息用于指示卫星的网络覆盖范围内包括终端设备的PLMN。本申请实施例对广播信息的具体内容不作限定，可选地，广播信息包括至少一个PLMN的标识，如至少一个PLMN ID。
步骤534，终端设备按照至少一个卫星网络的广播信息以及m个PLMN的优先级顺序，从m个PLMN中选择目标PLMN。
终端设备进入卫星的网络覆盖范围时，即可接收卫星网络的广播信息。之后，终端设备按照至少一个卫星网络的广播信息以及m个PLMN的优先级顺序，从m个PLMN中选择目标PLMN，也即进行卫星通信时使用的PLMN。可选地，m个PLMN的优先级顺序由候选网络信息集合指示，例如，如图6所示，针对候选信息集合中的每一个子集合，该子集合中指示的PLMN的排列顺序，即为该子集合指示的PLMN的优先级顺序。终端设备接收到卫星网络的广播信息，即可获取可接入的PLMN，再根据可接入的PLMN以及当前所处位置对应的可用PLMN的优先级顺序选择目标PLMN。
例如，假设至少一个卫星网络的广播信息指示两个可接入的PLMN，分别为PLMN 1和PLMN 2，终端设备当前所处位置对应的可用PLMN(m个PLMN且m为4)及其优先级顺序分别为：PLMN 3、PLMN 1、PLMN 2、PLMN 4，那么，根据至少一个卫星网络的广播信息和m个PLMN的优先级顺序，终端设备选择的目标PLMN为PLMN 1。
在另一个示例中，如图7所示，上述步骤530包括如下几个子步骤：
步骤531，终端设备显示m个PLMN。
终端设备在确定了当前所处的位置，并且选择出当前所处的位置对应的可用PLMN(m个PLMN)之后，可以将这m个PLMN显示在用户界面中，以呈现给用户并供用户进行自主选择。
步骤533，终端设备在到针对m个PLMN中目标PLMN的选择指令时，选择目标PLMN。
用户在从终端设备显示的m个PLMN中选择目标PLMN，终端设备即可接收到用户针对目标PLMN的选择指令，进而终端设备选择目标PLMN进行卫星通信。本申请实施例对触发终端设备接收到针对目标PLMN的选择指令的方式不作限定，可选地，终端设备显示有m个PLMN分别对应的选项，用户通过触控目标PLMN对应的选项，以触发终端设备接收到针对目标PLMN的选择指令；或者，用户通过语音、手势、AI(Artificial Intelligence，人工智能)等触发终端设备接收到针对目标PLMN的选择指令。
综上所述，本申请实施例提供的技术方案，通过终端设备根据当前所处位置对应的可用PLMN的优先级顺序以及接收到的卫星网络的广播信息，从当前所处位置对应的可用PLMN中选择进行卫星通信时使用的PLMN，实现了自动选择PLMN。另外，本申请实施例提供的技术方案，通过终端设备将当前所处位置对应的可用PLMN呈现给用户，以供用户自主选择进行卫星通信时使用的PLMN，满足了用户更多的操作需求。
下面，结合几个示例对本申请的技术方案进行介绍说明。
请参考图8，其示出了本申请一个实施例提供的网络选择方法的示意图。
假设网络覆盖范围内包括终端设备的卫星网络包括卫星网络1和卫星网络2。其中，卫 星网络1覆盖国家1和国家2，卫星网络1的广播消息中包括：PLMN 1：MCC 1+MNC 1；卫星网络2覆盖国家1，卫星网络2的广播消息中包括：PLMN 2：MCC 2+MNC 2。假设终端设备的归属国家为国家1，归属PLMN为PLMN 1。假设PLMN 1在国家2没有地面接收站，则PLMN 1在国家2不可用。
在终端设备当前位于国家2时，终端设备位于归属国家之外的国家，也即，终端设备处于漫游状态，此时，终端设备在进行网络选择时，仅以国家2对应的可用PLMN进行网络选择，即终端设备选择PLMN2；同时，终端设备停止运行扫描定时器，以避免在国家2时优先选择不可用的归属PLMN，即避免选择PLMN 1。
请参考图9，其示出了本申请另一个实施例提供的网络选择方法的示意图。
假设网络覆盖范围内包括终端设备的卫星网络包括卫星网络1和卫星网络2。其中，卫星网络1覆盖国家1和国家2，卫星网络1的广播消息中包括：PLMN 1：MCC 1+MNC 1；卫星网络2覆盖国家1，卫星网络2的广播消息中包括：PLMN 2：MCC 2+MNC 2。假设终端设备存储的注册PLMN为PLMN 1。假设PLMN 1在国家2没有地面接收站，则PLMN 1在国家2不可用。
在终端设备开机或重新进入网络覆盖区域的情况下，如图9所示，终端设备从无网络覆盖区域进入国家2，此时，终端设备在进行网络选择时，不优先选择存储的注册PLMN，也即不优先选择PLMN 1，而是依据国家2对应的可用PLMN进行网络选择，也即，终端设备选择PLMN 2。
请参考图10，其示出了本申请又一个实施例提供的网络选择方法的示意图。
假设网络覆盖范围内包括终端设备的卫星网络包括卫星网络1和卫星网络2。其中，卫星网络1覆盖国家1和国家2，卫星网络1的广播消息中包括：PLMN 1：MCC 1+MNC 1；卫星网络2覆盖国家1，卫星网络2的广播消息中包括：PLMN 2：MCC 2+MNC 2。假设PLMN1在国家2没有地面接收站，则PLMN 1在国家2不可用。
在终端设备位于国家1的情况下，终端设备将国家1对应的可用PLMN呈现给用户，也即，将PLMN 1呈现给用户，以供用户选择。在终端设备位于国家2的情况下，终端设备将国家2对应的可用PLMN呈现给用户，也即，将PLMN 2呈现给用户，以供用户选择。
