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清楚描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了 在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6 th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的结构图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端 (PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装、游戏机等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
本申请实施例中，凭证，是指用于在终端接入的网络内用于识别终端和认证终端所用的信息。
凭证持有者，是指凭证所属的实体，如终端的归属运营商、服务提供商或其他第三方实体。
在一实施例中，终端支持非公共网络的接入，对于非公共网络来说，可能只在特定的时间或地点提供特定的服务，例如某个体育馆在某个时间段举行比赛，提供数据传输服务。
终端可以根据SNPN的签约或PLMN的签约接入SNPN网络。如果终端激活SNPN接入模式(SNPN access mode)时，只能接入SNPN网络。若此时没有合适的SNPN网络可供接入，终端也无法接入其他网络，从而影响终端的通信；终端还可以根据PLMN的签约接入PNI-NPN。当终端的签约配置了仅支持封闭接入组(closed access group，CAG)，即CAG only的时候，终端只能接入PNI-NPN，如果此时没有合 适的PNI-NPN网络可供接入，终端也不能接入普通PLMN的小区，这时会影响终端的通信。
针对上述几种不同的网络，为了不影响终端的通信，对于本领域技术人员来说，终端如何选择合适的网络进行接入成为亟待解决的问题。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的网络选择方法进行详细地说明。
图2是本申请实施例提供的网络选择方法的流程示意图之一。如图2所示，本实施例提供的网络选择方法，包括：
步骤101、终端获取网络选择策略信息。网络选择策略信息包括：至少一个网络的网络标识和至少一个网络对应的网络选择条件，至少一个网络包括至少一个非公共网络；
可选地，网络选择条件包括以下至少一项：时间信息、位置信息、服务参数信息。
具体地，终端基于该网络选择策略信息进行网络选择，从而接入选择的网络。
网络选择策略信息包括：至少一个网络的网络标识和网络选择条件，其中，网络选择条件可以适用于某一个网络，或者多个网络，也可以适用于该网络选择策略信息中所有的网络。例如，用户控制的网络列表中每一项包括一个网络的标识和对应的网络选择条件，则该网络选择条件适用于该网络；或者，用户控制的网络列表中每一项包括多个网络的标识和对应的网络选择条件，则该网络选择条件适用于对应的多个网络；或者，用户控制的网络列表中包括多个网络的标识和一个网络选择条件，则该网络选择条件用于该用户控制的网络列表中所有的网络。当网络选择条件或者网络选择条件中的某一项不存在或为空时，则说明对应的网络没有网络选择条件的限制，或者没有某一项网络选择条件的限制。
其中，上述网络可以是公共网络和/或非公共网络，可选地，包括以 下至少一项：独立非公共网络SNPN、公共网络集成的非公共网络PNI-NPN或公共网络。可选地，公共网络为PLMN。
可选地，终端可以分别获取非公共网络选择策略信息和公共网络选择策略信息，即这两种网络的网络选择策略信息可以不在同一个信息列表中携带，例如通过两个信息列表携带。这两种网络的网络选择策略信息可以在不同的地方或从不同的消息中获得，也可以在同一个地方或同一条消息中不同的信息列表中获得。
可选地，上述两种网络的网络选择策略信息也可以在同一个信息列表中携带。
可选地，公共网络选择策略信息与非公共网络选择策略信息可以不同。
其中，网络选择条件中时间信息指示在该时间信息描述的时间时，终端可以选择该网络。地点信息指示当终端处于该地点信息描述的地点时，终端可以选择该网络。当网络选择条件同时包括时间信息和地点信息时，则需要在时间信息和地点信息同时满足时，终端可以选择该网络。
服务参数信息，可以包括以下至少一项：服务标识service ID，应用程序标识App ID，业务描述(traffic description)等。服务参数说明了终端可以使用对应的网络访问该服务参数所指示的服务。
在一个网络选择条件中，服务参数、时间信息和地点信息可以只出现其中一个或多个。其中，服务参数、时间信息和地点信息可以放在不同的参数中携带，也可以放在同一个参数中，本申请不做限制。
可选地，网络选择策略信息中还可以包括一个默认网络选择条件，且该默认网络选择条件无对应的网络标识。这表示当终端没有选择到网络选择策略信息中所有的网络标识所指示的网络时，如果还有网络可以选择，其中该网络为允许终端接入的网络，但该终端配置的可接入网络不包含该网络，则可以使用该默认网络选择条件确定该网络是否满足网 络选择条件。
值得说明的是，终端也可以通过不同方式获得网络选择策略信息。例如，终端可以被用户配置用户控制的网络列表，其中包括网络选择策略信息，还可以从归属运营商获得凭证持有者控制的网络列表，其中包括网络选择策略信息。在后续的网络选择过程中，终端可以根据特定优先级顺序根据通过不同方式获取的网络选择策略信息进行网络选择。
步骤102、终端根据至少一个网络对应的网络选择条件，确定待接入的目标网络。
在本申请实施例中，确定一个网络，也可以称为选择一个网络。
具体地，终端确定至少一个网络中是否存在满足对应的网络选择条件的网络，若存在，即将该满足网络选择条件的网络确定为目标网络，即选择该目标网络进行接入。
若满足网络选择条件的网络有多个，还可以根据多个网络的优先级信息和/或信号测量结果，选择目标网络。
可选地，目标网络包括以下至少一项：独立非公共网络SNPN、公共网络集成的非公共网络PNI-NPN或公共网络。
终端可以执行上述步骤102选择公共网络或非公共网络。终端选择公共网络或非公共网络的执行顺序不作限定。也可以分别执行一次或多次，本申请不作限定。
可选地，如果终端没有选择到非公共网络，可以继续选择公共网络。
可选地，如果终端没有选择到公共网络，可以继续选择非公共网络。
可选地，如果终端选择到合适的非公共网络，当该非公共网络的网络选择条件不再满足时，终端根据上述步骤再次选择非公共网络。
可选地，如果终端选择到合适的非公共网络，当该非公共网络的网络选择条件不再满足时，终端根据上述步骤或者3GPP协议中的方案选择 公共网络。可选地，如果终端没有选择到合适的公共网络，则终端根据上述步骤再次选择非公共网络。
可选地，如果终端选择到合适的公共网络，当该公共网络的网络选择条件不再满足时，终端根据上述步骤选择非公共网络。
可选地，如果终端选择到合适的非公共网络，还可以继续根据上述步骤进行公共网络选择。如果终端选择到合适的公共网络，还可以继续根据上述步骤进行非公共网络选择。
本实施例的方法，终端根据至少一个网络对应的网络选择条件，选择目标网络进行接入，其中至少一个网络包括至少一个非公共网络；网络选择条件包括以下至少一项：时间信息、位置信息、服务参数信息，上述方案在具有非公共网络的场景下，选择满足该网络选择条件的目标网络，即目标网络能够满足时间、位置、服务参数等信息的约束，也即终端能够选择到合适的网络进行接入，网络选择的准确性较高。
在一实施例中，步骤102之前还可以包括：
激活条件非公共网络接入模式。
具体的，在根据步骤102选择目标网络之前，可以激活条件非公共网络接入模式。在该条件非公共网络接入模式下，执行步骤102的网络选择过程，例如可以选择非公共网络和/或公共网络接入。
条件非公共网络接入模式，对选择的接入网络的类型不作限定，可以是非公共网络也可以是公共网络。即只要满足相应的网络选择条件就可以选择该网络。
需要说明的是，条件非公共网络接入模式只是一个名称，也可以替换为其他名称，如第一模式等，本申请实施例对此并不限定。
可选地，步骤102之前还可以包括如下步骤：
激活非公共网络接入模式，确定待接入的所述目标网络为非公共网络；或，
去激活非公共网络接入模式，确定待接入的所述目标网络为公共网 络。
具体地，选择非公共网络之前，即需要选择的目标网络为非公共网络之前，激活非公共网络接入模式，例如非公共网络为SNPN，激活SNPN access mode。
假设在非公共网络接入模式下，只允许选择非公共网络，则在选择公共网络之前，即需要选择的目标网络为公共网络之前，去激活非公共网络接入模式。
可选地，该方法还可以包括如下步骤：
当目标网络的网络选择条件不再满足时，去激活非公共网络接入模式。其中，目标网络为非公共网络，进一步终端执行步骤102；或者，
当目标网络的网络选择条件不再满足时，激活非公共网络接入模式。其中，目标网络为公共网络，进一步终端执行步骤102。
具体地，当选择或接入的目标网络的网络选择条件不再满足时，可以重新选择满足网络选择条件的网络，并尝试接入，例如可以选择公共网络或非公共网络。假设当前的目标网络为非公共网络，终端在选择目标网络之前激活了非公共网络接入模式(access mode)，若在该非公共网络接入模式下只能接入非公共网络，则当该非公共网络不再满足网络接入条件时，也无其他非公共网络可以选择时，终端也无法选择其他公共网络接入，影响终端的通信。因此，可以在重新选择公共网络时去激活非公共网络接入模式；可选地，终端可以不去激活非公共网络接入模式，重新选择其它的非公共网络。本申请实施例并不限定。
假设当前的目标网络(即当前接入或选择的网络)为公共网络，重新选择的网络为非公共网络，则在重新选择之前先激活非公共网络接入模式。可选地，目标网络为公共网络，重新选择的网络也可以是公共网络，则在重新选择之前无需激活非公共网络接入模式。本申请实施例并不限定。
上述实施方式中，可以通过接入模式，限定网络的选择。
如图3所示，本申请实施例提供一种网络选择的方法，该方法包括：
步骤100a、网络侧设备向终端发送网络选择策略信息；
步骤101、终端获取100a中的网络选择策略信息；
步骤102、终端根据网络选择策略信息中的至少一个网络对应的网络选择条件，确定待接入的目标网络。
步骤101和102可以参考前面的描述。
步骤103、终端执行接入过程。
可选地，网络选择策略信息通过以下至少一项携带，由网络设备向终端发送：
用户控制的网络列表；
凭证持有者控制的网络列表；
凭证持有者控制的组标识GIN列表；
路由选择策略URSP；
注册接受消息；
会话建立接受消息；
非接入层NAS消息。
具体地，用户控制的网络列表包括：用户允许或倾向选择的网络的信息和网络选择条件。网络的信息可以包括网络的标识。以SNPN网络为例，SNPN网络的标识可以包括PLMN ID和网络标识(Network identifier，NID)，可选的还可以包括GIN；以PNI-NPN网络为例，PNI-NPN网络的标识可以包括CAG ID。
凭证持有者控制的网络列表包括：凭证持有者允许或倾向选择的网络的信息和网络选择条件。网络的信息和网络选择条件可以参考上述描述。
凭证持有者控制的GIN列表，可选地，该GIN列表可以包括GIN的优先级信息。该GIN列表包括了凭证持有者允许或倾向选择的网络所属 的组的组标识GIN和网络选择条件。网络选择条件可以参考上述描述。
URSP可以包括网络标识和网络选择条件。其中，网络选择条件可以参考前述实施例中关于网络选择条件的说明。
示例性的，以终端设备在注册过程中获取网络选择策略信息为例，如图4所示，本申请实施例提供一种网络选择的方法，该方法包括：
步骤100b、终端向鉴权管理域(Authentication Management Field，AMF)发送注册请求消息。该注册请求消息用于请求注册到该AMF。
步骤100c、终端从AMF接收注册接受消息。该注册接受消息中可以包括网络选择策略信息。
其中，网络选择条件中的地点信息可以包括以下至少一项：一个或多个小区(例如通过小区列表表示)，一个或多个跟踪区(例如通过跟踪区域(Tracking Area，TA)列表表示)，一个或多个地理位置(例如通过Geo列表表示)，一个或多个经纬度(例如通过经纬度列表表示)。
可选地，终端也可以在会话建立过程中获得网络选择策略信息。上述图4中注册请求消息和注册接受消息可以相应替换为会话建立请求消息和会话建立接受消息。
可选地，终端还可以通过其他非接入层(Non-Access Stratum，NAS)消息获得网络选择策略信息。其他NAS消息例如可以包括下行NAS传输消息(DL NAS TRANSPORT消息)，或终端配置更新命令消息(Configuration Update Command消息)等。
可选地，网络选择策略信息可以预先配置在终端中，或，来自于终端的归属网络的网络设备或所属的服务提供商设备。网络侧设备例如可以是核心网设备或基站等。
其中，网络选择策略信息可以被用户或运营商等预先配置在终端中。
在一实施例中，步骤102具体可以通过如下方式实现：
一种方式：
终端按照第一优先级顺序确定满足网络选择条件的第一网络为目标网络；
其中，第一优先级表示网络的优先级的高低顺序。
可选地，所述网络的优先级包括以下至少两项的优先级：终端前一次注册的网络、终端签约的网络、用户控制的网络列表中的网络、凭证持有者控制的网络列表中的网络、凭证持有者控制的组标识GIN列表中包括的组中的网络、第二网络，第二网络为终端配置的可接入网络之外允许终端接入的网络。
具体地，终端按照第一优先级顺序依次确定第一优先级顺序中的各个网络是否满足网络选择策略中对应的网络选择条件，且是否是可以选择的网络，若某个网络满足对应的网络选择条件，且是可以选择的网络，则确定该网络为目标网络。
作为一种具体的实施方式，终端确认某个网络是否是可以选择的网络，包括：终端搜索该网络，如果能够搜索到，则确认该网络是可以选择的网络，否则不是。
作为另一种具体的实施方式，终端在确定目标网络之前，获取当前可以选择的网络。例如，终端可以搜索附近的网络，获取当前可以选择的网络的列表。当终端按照第一优先级顺序确认某个网络满足对应的网络选择条件，且该网络是当前可以选择的网络时，则确认该网络是可以选择的网络，否则不是。
第一优先级顺序可以为按照优先级进行的降序排列，或升序排序。本实施例以第一优先级顺序为按照优先级降序排列为例。例如，终端前一次注册的网络为第一优先级，优先级最高，终端签约的网络为第二优先级，依此类推。值得说明的是，在实际实施的网络选择过程中，可能只考虑第一优先级顺序中的部分网络。例如，按照用户控制的网络列表中的网络、凭证持有者控制的网络列表中的网络、凭证持有者控制的组 标识GIN列表中包括的组中的网络的顺序进行网络选择。或者，只根据凭证持有者控制的网络列表中的网络进行网络选择。
例如，终端按照第一优先级顺序首先查看至少一个网络中是否有终端前一次注册的网络，若有则确定该网络是否满足对应的网络选择条件，若不满足则继续选择其他网络，若至少一个网络中没有终端前一次注册的网络，则继续查找是否有下一优先级的网络，即终端签约的网络，若有，则查看是否满足对应的网络选择条件，依此类推，直到找到一个满足网络选择条件的网络，或，全部网络中都不满足网络选择条件。
可选地，如果终端支持使用鉴权凭证持有者的凭证接入网络，网络侧可以广播自己支持终端使用鉴权凭证持有者的凭证接入。终端可以按照下列优先级来选择网络并尝试接入：
用户控制的网络列表中的网络；
凭证持有者控制的网络列表中的网络；
凭证持有者控制的GIN列表中包括的GIN对应的组中的网络。假设某个网络广播该网络对应的GIN，该GIN包括凭证持有者控制的GIN列表中包括的GIN，则该网络属于此类。
第二网络，终端配置的可接入网络之外允许终端接入的网络。换而言之，某个网络广播允许终端接入，该终端配置的可接入网络不包括本网络，也即该网络广播的NID或GIN不在终端的凭证持有者控制的网络列表中。值得说明的是，第二网络可能不在终端所获取到的网络选择策略信息中，此时终端只能通过搜索才能发现这些第二网络。因此第二网络属于当前可以选择的网络。
以上第一优先级顺序中的每一项可能涉及多个网络，这多个网络之间如果有优先级关系，则按照优先级关系在这多个网络之间进行选择。例如，用户控制的网络列表中可能包括多个网络，且用户控制的网络列表也指示了这多个网络之间的优先级关系，则终端在尝试选择用户控制 的网络列表中的网络时，按照用户控制的网络列表中的优先级选择其中的网络，即按照优先级依次确定用户控制的网络列表中的网络是否满足对应的网络选择条件。
可选地，如果多个网络可用，且广播了相同的GIN，终端可以选择这多个网络中的一个网络并尝试接入。例如，终端随机选择一个网络尝试接入，如果失败再选下一个网络并尝试接入。其中，网络可用指的是该网络满足对应的网络选择条件。
可选地，终端也可以根据自己当前需要使用的服务来进行网络选择。例如当终端需要使用语音服务时，按照上述第一优先级顺序确定某个网络的网络选择条件中的服务参数是否包括语音服务，如果包括，则当前该网络的网络选择条件满足，可以接入该网络。
上述实施方式中，终端按照网络优先级高低的第一优先级顺序确定满足网络选择条件的第一网络为目标网络，能够选择合适的网络进行接入，优先级较高的网络，终端接入的成功率也较高，因此提高了选网准确度和效率。
可选地，当目标网络的网络选择条件不再满足时，终端按照第一优先级顺序确定满足网络选择条件的第三网络，第三网络为：公共网络或非公共网络。
具体地，当选择或接入的目标网络的网络选择条件不再满足时，可以重新选择第三网络，并尝试接入，例如可以选择公共网络或非公共网络。其中，第三网络为新的目标网络。选择第三网络的过程可以参考前面选择目标网络的过程的描述。
假设当前的目标网络为非公共网络，重新选择的网络可以为公共网络，也可以为非公共网络，本申请实施例并不限定。
假设当前的目标网络为公共网络，重新选择的网络可以为非公共网络，也可以是公共网络，本申请实施例并不限定。
可选地，该方法还包括：
终端按照第一优先级顺序确定满足网络选择条件的待接入的第四网络，其中按照上述目标网络选择过程选择的目标网络为非公共网络，则第四网络为公共网络；或，按照上述目标网络选择过程选择的目标网络为公共网络，则第四网络为非公共网络。
具体地，终端在选择了一个目标网络后，还可以选择其他网络进行接入，即终端可以同时接入不同的网络，例如终端同时接入非公共网络和公共网络。
假设当前的目标网络为非公共网络，则进一步还可以选择一个公共网络进行接入，或者，当前的目标网络为公共网络，则选择非公共网络进行接入。选择公共网络的过程可以参考上述选择目标网络的过程或者3GPP协议中的描述。选择非公共网络的过程可以参考上述选择目标网络的过程的描述。
另一种方式：
终端按照路由选择策略(UE Route Selection Policy，URSP)包括的第二优先级顺序，确定满足网络选择条件的第一网络为目标网络；其中，所述第二优先级顺序表示网络的优先级的高低顺序。
具体地，终端按照第二优先级顺序依次确定终端可以选择的多个网络是否满足对应的网络选择条件，若某个网络满足对应的网络选择条件，则确定该网络为目标网络。
第二优先级顺序可以为按照优先级进行的降序排列，或升序排序。第二优先级顺序为终端可以选择的多个网络的优先级的高低顺序。
示例性的，URSP包括网络标识和网络选择条件。其中，网络选择条件可以参考前述实施例中关于网络选择条件的说明。在某个网络的网络选择条件满足时，可以选择该网络标识所指示的网络。例如，在网络选择条件中包括的时间和/或地点条件满足时，终端使用网络选择条件中的服务参数所指示的服务时，可以选择对应的网络。
网络选择条件也可以理解为描述了该网络的接入信息，例如，该网 络在对应的时间和/或地点可以接入或生效，该网络支持对应的服务参数所指示的服务。
可选地，URSP中可以包括优先级列表，该优先级列表指示了网络的优先级顺序，例如，优先级列表中是按照网络支持的服务进行分类的，每一类描述了特定服务对应的网络，以及网络选择条件，多个分类之间是按照优先级高低顺序排列的。可选地，若某一类中包括多个网络，还可以包括多个网络之间的优先级信息。可选地，每一类中的网络选择条件可以是一个或多个，或者，优先级列表中可以只包括一个网络选择条件。
示例性的，终端根据URSP中的优先级列表，按照URSP中的优先级列表指示的第二优先级顺序依次确定终端可以选择的多个网络的网络选择条件是否满足，如果当前网络的网络选择条件满足了，则终端尝试接入该网络，否则确定下一优先级的网络的网络选择条件是否满足。
示例性的，终端当前需要使用某特定业务，终端按照URSP指示的第二优先级顺序确定多个网络的网络选择条件，如果当前网络的网络选择条件包括该特定业务，且网络选择条件中的其他条件已满足，则终端尝试接入该网络，否则确定本优先级的下一个网络或下一优先级的网络的网络选择条件是否满足。
可选地，当目标网络的网络选择条件不再满足时，终端按照第二优先级顺序确定满足网络选择条件的第三网络，第三网络为：公共网络或非公共网络。
具体地，当选择或接入的目标网络的网络选择条件不再满足时，可以重新选择满足网络选择条件的第三网络，并尝试接入，例如可以选择公共网络或非公共网络。其中，第三网络为新的目标网络。
假设当前的目标网络为非公共网络，重新选择的网络可以为公共网络，也可以为非公共网络，本申请实施例并不限定。
假设当前的目标网络为公共网络，重新选择的网络可以为非公共网 络，也可以是公共网络，本申请实施例并不限定。
可选地，该方法还包括：
终端按照第二优先级顺序确定满足网络选择条件的待接入的第四网络，其中按照上述目标网络选择过程选择的目标网络为非公共网络，则第四网络为公共网络；或，按照上述目标网络选择过程选择的目标网络为公共网络，第四网络为非公共网络。
具体地，终端在选择了一个目标网络后，还可以选择其他网络进行接入，即终端可以同时接入不同的网络，例如终端同时接入非公共网络和公共网络。
假设当前的目标网络为非公共网络，则进一步还可以按照第二优先级顺序选择公共网络进行接入，或者，当前的目标网络为公共网络，则进一步还可以按照第二优先级顺序选择非公共网络进行接入。
可选地，第一优先级顺序和第二优先级顺序可以只用来选择非公共网络。其中，本申请中的按照第一优先级顺序或第二优先级顺序选择公共网络的方案，可以替换为按照获取的公共网络选择策略信息选择公共网络的方案，或者替换为按照3GPP协议中描述的公共网络选择方案。
上述实施方式中，终端按照网络优先级高低的第二优先级顺序确定满足网络选择条件的第一网络为目标网络，能够选择合适的网络进行接入，优先级较高的网络，终端接入的成功率也较高，因此提高选网效率和准确率。
可选地，第一网络为多个，确定满足网络选择条件的第一网络为目标网络，具体可以通过如下方式实现：
所端基于多个第一网络的信号测量结果，确定所述目标网络；和/或，
终端基于多个第一网络的优先级信息，确定所述目标网络。
具体地，如果满足网络选择条件的第一网络有多个，则终端可以根据多个网络的信号测量结果，确定最终的目标网络并尝试接入。例如选 择信号质量最好的网络作为目标网络。
