具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请技术方案的一部分实施例，而不是全部的实施例。基于本申请文件中记载的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请技术方案保护的范围。
现有技术，在UE同时通过3GPP接入类型接入到核心网以及通过非3GPP接入类型接入到核心网的场景下，若网络接收到需要对UE进行定位服务的请求时，主要通过AMF(Access and Mobility Management Function，接入和移动性管理功能)或LMF(Location Management Function，位置管理功能)选择接入类型。
例如，如图1所示，为现有技术中通过AMF选择接入类型的过程，包括：外部位置服务客户端向GMLC(Gateway Mobile Location Centre，网关移动位置中心)发送请求，请求中携带目标UE标识符；GMLC向目标UE的家乡UDM(Unified Data Manager，统一数据管理)调用Nudm_UECM_Get服务操作；UDM返回当前服务AMF的网络地址；GMLC向AMF调用Namf_Location_ProvideLocation服务操作，以请求UE当前的位置；如果UE处于CM-IDLE状态，AMF发起网络触发的业务请求过程，与UE建立信令连接；AMF根据NRF请求或配置信息选择LMF(Location Management Function，位置管理功能)，并向LMF调用Nlmf_Location_DetermineLocation服务操作，以请求UE当前的位置；LMF执行定位过程，例如，现有技术中的UE协助的定位过程，网络协助的定位过程等。LMF向AMF返回Nlmf_Location_DetermineLocation Response，以返回UE当前的位置，该UE当前的位置可以包括位置估计信息，时间以及精确度等信息；AMF向GMLC/LRF返回Namf_Location_ProvideLocation Response，以返回UE当前的位置；GMLC向外部位置服务客户端返回位置服务回复。
然而，在实际应用中，本申请的发明人发现，UE同时通过3GPP接入类型以及非3GPP接入类型接入到核心网时，为UE服务的AMF可能相同，也可能不同，而现有技术只适用于为UE服务的AMF相同的场景，而在为UE服务的AMF不同的场景下，现有技术并 不能实现对UE的定位服务，为此，本申请实施例提出一种接入类型选择方法，用于解决现有技术中，在3GPP接入类型以及非3GPP接入类型接入下，为UE服务的AMF不同时，存在不能实现对UE的定位服务的技术问题。
下面结合说明书附图对本申请实施例作进一步详细描述。
实施例一
参见图2所示，本申请实施例一种接入类型选择方法，该方法包括以下步骤：
步骤S101：UDM接收GMLC发送的第一请求。
步骤S102：所述UDM确定用于传输定位信息的接入类型，并向所述GMLC发送所述接入类型。
本申请实施例中的接入类型的选择方法，可应用于UE同时通过3GPP接入类型和非3GPP(non-3GPP)接入类型连接至核心网的应用场景，在该应用场景下，当LCS(Location Service，位置服务)客户端需要获得UE的位置信息时，如图3所示，LCS客户端即图3中的LCS Client，可以向GMLC发送LCS服务请求，LCS服务请求中携带UE的标识符，UE的标识符可以具体为UE的GPSI(Generic Public Subscription Identifier，通用公共签约标识符)，也可以为UE的SUPI(Subscription Permanent Identifier，签约静态标识符)。在实际应用中，LCS服务请求可以具体为LCS Service Request消息，在该LCS Service Request消息中携带UE的标识符。
GMLC接收到LCS客户端发送的LCS服务请求之后，向UDM发送第一请求，所述第一请求中包括UE的标识符，在实际应用中，如图3所示，第一请求具体为Nudm_UEContextManagement_Get Request消息，该消息中携带UE的标识符。UDM获得第一请求之后，UDM确定用于传输定位信息的接入类型，并将确定的接入类型通过Nudm_UEContextManagement_Get Response消息发送给GMLC。
在实际应用中，上述步骤S102中的UDM确定用于传输定位信息的接入类型，可以通过如图4所示的流程具体实现。
图4所示的流程包括：
步骤S201：UDM获取第一信息，所述第一信息包括以下信息中的至少一种：UE使用的所有接入类型，为所述UE服务的AMF，以及所UE在每种接入类型内的状态信息。
步骤S202：所述UDM根据所述第一信息，从所述所有接入类型中，确定用于传输定位信息的接入类型。
在本申请实施例中，UDM获得第一请求之后，可以根据第一请求中携带的UE标识信息，获取与UE相关的第一信息，这里的第一信息可以为UE使用的所有接入类型，也可以为UE服务的AMF，还可以为UE在每种接入类型内的状态信息等等，当然，也可以同时为上述列举的多种信息。下面对UDM根据第一请求中携带的UE标识信息，获取与UE相关的第一信息的过程进行描述。
在具体实践过程中，当UE通过3GPP接入类型或通过非3GPP接入类型注册时，UE会通过接入网络向AMF发送注册请求，在UE注册过程中，AMF向UDM注册UE信息，此时AMF向UDM提供信息包括UE的标识，AMF标识以及接入类型。
如果UE通过3GPP接入类型注册的服务AMF不同于UE通过非3GPP接入类型注册的服务AMF，为叙述方便，这里将UE通过3GPP接入类型注册的服务AMF称为AMF1，将UE通过非3GPP接入类型注册的服务AMF称为AMF2，则UDM存储的信息可以为： 《UE标识，<3GPP接入，AMF1的信息>，<非3GPP接入，AMF2的信息>》，其中，AMF1信息可以是AMF1的IP地址或FQDN(Fully Qualified Domain Name，全限定域名)，AMF2信息可以是AMF2的IP地址或FQDN。
如果UE通过3GPP接入类型注册和通过非3GPP接入类型注册的服务AMF相同，这里为叙述方便，假设该AMF为AMF3，则UDM存储的信息可以为：《UE标识，<3GPP接入，AMF3的信息>，<非3GPP接入，AMF3的信息>》，或者UDM存储的信息可以为：《UE标识，AMF3的信息，3GPP接入，非3GPP接入》。
因此，UDM可从本地存储的信息中获得第一信息，例如，从本地存储的信息中获取UE使用的所有接入类型，也即3GPP接入类型以及非3GPP接入类型，还可以从本地存储的信息中获取UE通过3GPP接入类型注册时，为UE服务的AMF，以及获取UE通过非3GPP接入类型注册时，为UE服务的AMF。因此，根据获取的上述信息，进一步判断UE通过3GPP接入类型注册和通过非3GPP接入类型注册时，为UE服务的AMF是否相同。
例如，UDM根据获得的上述信息，判断出UE通过3GPP接入类型注册和通过非3GPP接入类型注册时，为UE服务的AMF不同时，这里假设UE通过3GPP接入类型注册时，为UE服务AMF为AMF1，UE通过非3GPP接入类型注册时，为UE服务AMF为AMF2，那么，UDM就可以向AMF1发送Namf_EventExposure消息，获取UE在3GPP接入类型内的状态信息，该状态信息可以包括UE在3GPP接入类型中注册状态改变(注册态或去注册态)、连接态的改变(空闲态或连接态)、UE可达性状态等。
同样的，UDM可以向AMF2发送Namf_EventExposure消息，获取UE在非3GPP接入类型内的状态信息，该状态信息可以包括UE在非3GPP接入类型中注册状态改变(注册态或去注册态)、连接态的改变(空闲态或连接态)、UE可达性状态等。
例如，UDM根据获得的上述信息，判断出UE通过3GPP接入类型注册和通过非3GPP接入类型注册时，为UE服务的AMF相同时，这里假设该相同的AMF为AMF3，那么，UDM就可以向AMF3发送Namf_EventExposure消息，获取UE在3GPP接入类型内的状态信息，以及UE在非3GPP接入类型内的状态信息。
UDM在根据上文中的叙述方式获得UE使用的所有接入类型，为UE服务的AMF，以及所UE在每种接入类型内的状态信息之后，就可以根据获得的上述信息，从所有接入类型中也即3GPP接入类型和非3GPP接入类型中，确定用于传输定位信息的接入类型。在实际应用中，UDM还可以结合获得上述信息以及运营商策略决定用于传输定位信息的接入类型。
例如，在3GPP接入类型下，为UE服务的AMF为AMF1，在非3GPP接入类型下，为UE服务AMF为AMF2时，若UE在3GPP接入类型内的空闲态即CM-IDLE状态，在非3GPP接入类型处于连接态即CM-CONNECTED状态，UDM就可以确定非3GPP接入类型用于传输定位信息。若UE在3GPP接入类型内处于CM-CONNECTED状态，在非3GPP接入状态处于CM-IDLE状态，UDM就可以确定3GPP接入类型传输定位信息。
在本申请实施例中，定位信息可以是UE的位置，如地理位置、城市位置(如UE所在的街道、城市)等，还可以是获取UE位置的时间信息，也可以是获取UE位置使用的定位方法、定位精度等与定位相关的信息，还可以是与执行定位过程相关的消息，如AMF发送给RAN节点或N3IWF的网络定位消息、RAN节点或N3IWF返回给AMF的网络定位消息，当然，定位信息还可以是其他信息，在此就不一一列举了，也不做任何限制。
例如，若运营商策略包括：若UE在3GPP接入类型以及非3GPP接入类型中均处于CM-CONNECTED状态时，优先使用3GPP接入类型传输定位信息，那么，当UDM确定UE在3GPP接入类型内以及非3GPP接入类型中均处于CM-CONNECTED状态时，无论在3GPP接入类型下以及非3GPP接入类型下，为UE服务的AMF是否相同，UDM都可以确定使用3GPP接入类型传输定位信息。
在本申请实施例中，UDM在通过图4所示的流程确定用于传输定位信息的接入类型之后，可以向GMLC发送确定的接入类型。在本申请实施例中，向GMLC发送确定的接入类型的方式包括多种，下面对向GMLC发送确定的接入类型的多种方式进行介绍。
如图5所示，为向GMLC发送确定的接入类型的第一种方式，包括：
步骤S301：若所述UDM确定对于不同接入类型，为所述UE服务的AMF不同，则执行步骤302；
步骤S302：所述UDM向所述GMLC发送第一AMF的地址，所述第一AMF为在所述接入类型下，为所述UE服务的AMF的地址。
UDM确定对于不同接入类型，为所述UE服务的AMF不同时，例如，在3GPP接入类型下，为UE服务的AMF为AMF1，在非3GPP接入类型下，为UE服务AMF为AMF2，若UDM确定用于传输定位信息的接入类型为3GPP接入类型，那么，UDM就可以向GMLC发送AMF1的地址。在实际应用中，UDM可以通过Nudm_UEContextManagement_Get Response消息，向GMLC发送AMF1的地址。在实际应用中，在3GPP接入类型的定位架构如图6a所示，也即GMLC与AMF之间有接口，那么，GMLC在接收到UDM发送的AMF1的地址之后，GMLC就可以根据AMF1的地址向AMF1发送提供UE位置的请求信息，该请求信息可以具体为Provide Location Request消息。那么，AMF1在接收到GMLC发送的Provide Location Request消息之后，就会对UE执行3GPP接入类型内的定位过程，从而获得UE的位置信息，AMF1将获得的UE位置信息可以通过Provide Location Response消息反馈给GMLC，GMLC接收到该消息之后，将该消息中的UE位置信息反馈给LCS客户端。
若UDM确定用于传输定位信息的接入类型为非3GPP接入类型，那么，UDM就可以向GMLC发送AMF2的地址，进而GMLC向AMF2发送提供UE位置的请求信息，那么，AMF2在接收到GMLC发送提供UE位置的请求信息如Provide Location Request消息，就会对UE执行非3GPP接入类型内的定位过程，从而获得UE的位置信息，AMF2将获得的UE位置信息可以通过Provide Location Response消息反馈给GMLC，GMLC接收到该消息之后，将该消息中的UE位置信息反馈给LCS客户端。
所以，在上述方法中，UDM在接收GMLC发送的第一请求，第一请求如Nudm_UEContextManagement_Get Request，由UDM确定用于传输定位信息的接入类型，并向所述GMLC发送所述接入类型，进而解决了现有技术中，在3GPP接入类型以及非3GPP接入类型接入下，为UE服务的AMF不同时，存在不能实现对UE的定位服务的技术问题，到达在3GPP接入类型以及非3GPP接入类型接入下，为UE服务的AMF不同时，也能实现对UE的定位服务的目的。
在本申请实施例中，上述图5所示的向GMLC发送确定的接入类型的第一种方式中，还可以包括：UDM向GMLC发送LMF的地址。
例如，若UDM确定用于传输定位信息的接入类型为3GPP接入类型，UDM可以同时 向GMLC发送AMF1的地址以及LMF的地址，那么在3GPP接入类型的定位架构如图6b所示，也即GMLC与LMF之间有接口，那么，GMLC在接收到AMF1的地址以及LMF的地址之后，可以直接向LMF发送请求，进而，LMF执行3GPP接入类型内的定位过程，获得UE定位信息，从而LMF将UE定位信息传输给GMLC，GMLC反馈给LCS客户端。若UDM确定用于传输定位信息的接入类型为非3GPP接入类型，UDM也可以同时向GMLC发送AMF2的地址以及LMF的地址，后续过程可参考上述描述，在此就不重复叙述了。
如图7所示，为向GMLC发送确定的接入类型的第二种方式，包括：
步骤S303：若所述UDM确定对于不同接入类型，为所述UE服务的AMF相同，则执行步骤S304；
步骤S304：所述UDM向所述GMLC发送所述接入类型以及第二AMF的地址，所述第二AMF为在所述接入类型下、为所述UE服务的AMF的地址；
UDM确定对于不同接入类型，为所述UE服务的AMF相同时，例如，在3GPP接入类型下和非3GPP接入类型下，为UE服务的AMF均为AMF3，若UDM确定用于传输定位信息的接入类型为3GPP接入类型，那么，UDM就会向GMLC发送AMF3的地址以及3GPP接入类型，同样的，可以通过Nudm_UEContextManagement_Get Response消息将AMF3的地址以及3GPP接入类型发送给GMLC，以便GMLC根据接收到的AMF3的地址向AMF3发送3GPP接入类型以及提供UE位置的请求信息，提供UE位置的请求信息可以为Provide Location Request消息，因此，GMLC可以通过Provide Location Request消息携带3GPP接入类型发送给AMF3，AMF3在接收到GMLC发送的Provide Location Request消息之后，就会对UE执行3GPP接入类型内的定位过程，从而获得UE的位置信息，AMF3将获得的UE位置信息可以通过Provide Location Response消息反馈给GMLC，GMLC接收到该消息之后，将该消息中的UE位置信息反馈给LCS客户端。
若UDM确定用于传输定位信息的接入类型为非3GPP接入类型，那么，UDM就会向GMLC发送AMF3的地址以及非3GPP接入类型，以便GMLC根据接收到的AMF3的地址向AMF3发送非3GPP接入类型以及提供UE位置的请求信息，同样的，GMLC向AMF3发送的提供UE位置的请求信息可以为Provide Location Request消息，GMLC可以通过Provide Location Request消息携带非3GPP接入类型发送给AMF3，AMF3在接收到GMLC发送的非3GPP接入类型以及提供UE位置的请求信息之后，就会对UE执行非3GPP接入类型内的定位过程，从而获得UE的位置信息。
在本申请实施例中，上述图7所示的向GMLC发送确定的接入类型的第二种方式中，也可以包括：UDM向GMLC发送LMF的地址。
例如，若UDM确定用于传输定位信息的接入类型为非3GPP接入类型，UDM可以同时向GMLC发送AMF3的地址、非3GPP接入类型以及LMF的地址，那么在非3GPP接入类型的定位架构中，GMLC与LMF之间有接口，那么，GMLC在接收到AMF3的地址、非3GPP接入类型以及LMF的地址之后，可以直接向LMF发送非3GPP接入类型，进而，LMF执行非3GPP接入类型内的定位过程，获得UE定位信息，从而LMF将UE定位信息传输给GMLC，GMLC反馈给LCS客户端。
所以，通过上述方法，UDM在接收GMLC发送的第一请求，第一请求如Nudm_UEContextManagement_Get Request，由UDM确定用于传输定位信息的接入类型， 并向GMLC反馈接入类型，以及AMF的地址，GMLC可以向AMF发送接入类型，从而AMF可以使用确定的接入类型下的定位过程实现对UE的定位服务。不仅能够适用于UE在不同接入类型下，为UE服务的AMF不同的场景下的UE的定位服务，也适用于UE在不同接入类型下，为UE服务的AMF相同的场景下的UE的定位服务，所以，有效的解决了现有技术中，在3GPP接入类型以及非3GPP接入类型接入下，为UE服务的AMF不同时，存在不能实现对UE的定位服务的技术问题。
实施例二
参见图8所示，为本申请实施例提供的另一种接入类型选择方法，该方法包括以下步骤：
步骤S801：GMLC接收位置服务LCS客户端发送的第二请求；
步骤S802：GMLC确定用于传输定位信息的接入类型。
本申请实施例中的图8所示的接入类型的选择方法，也可应用于UE同时通过3GPP接入类型和非3GPP(non-3GPP)接入类型连接至核心网的应用场景，在该应用场景下，当LCS客户端(LCS Client)需要获得UE的位置信息时，LCS客户端可以向GMLC发送LCS服务请求，LCS服务请求就为步骤S801的第二请求，LCS服务请求中携带UE的标识符，UE的标识符可以具体为UE的GPSI，也可以为UE的SUPI。在实际应用中，LCS服务请求可以具体为LCS Service Request消息，在该LCS Service Request消息中携带UE的标识符。
GMLC接收到LCS客户端发送的LCS服务请求之后，可以确定用于传输定位信息的接入类型。其中，步骤S802可以通过如图9所示的流程实现。
图9所示的流程包括：
步骤S8021：GMLC获取第二信息，第二信息包括以下信息中的至少一种：所述UE使用的所有接入类型，为所述UE服务的AMF，以及所述UE在所述每种接入类型内的状态信息；
步骤S8022：GMLC根据所述第二信息，从所述所有接入类型中，确定用于传输定位信息的接入类型。
在本申请实施例中，GMLC可以获取UE使用的所有接入类型，也可以获取为UE服务的AMF，还可以获取UE在每种接入类型内的状态信息，GMLC获取上述信息的方式至少包括以下两种：
第一种方式：
步骤A：GMLC向UDM发送第三请求；
步骤B：GMLC接收UDM发送的第二信息，所述第二信息至少包括下一信息中的一种：UE使用的所有接入类型，为UE服务的AMF，以及UE在每种接入类型内的状态信息。
在本申请实施例中，GMLC接收到LCS客户端发送的LCS服务请求之后，GMLC可以向UDM发送第三请求，第三请求中包括UE的标识符，第三请求具体为Nudm_UEContextManagement_Get Request。UDM接收到第三请求之后，UDM可以如实施例一中的叙述方法获取到UE使用的所有接入类型，为UE服务的AMF，以及UE在每种接入类型内的状态信息，并将获取到的上述信息发送给GMLC，从而使得GMLC从UDM中获得UE使用的所有接入类型，为UE服务的AMF，以及UE在每种接入类型内的状态 信息。
GMLC根据获取的上述信息，即UE使用的所有接入类型，为UE服务的AMF，以及UE在每种接入类型内的状态信息，就可以从UE使用的所有接入类型，即3GPP接入类型和非3GPP接入类型中，确定用于传输定位信息的接入类型。在实际应用中，GMLC还可以结合获得上述信息以及运营商策略决定用于传输定位信息的接入类型。
其中，定位信息可以是UE的位置，如地理位置、城市位置(如UE所在的街道、城市)等，还可以是获取UE位置的时间信息，也可以是获取UE位置使用的定位方法、定位精度等与定位相关的信息，还可以是与执行定位过程相关的消息，如AMF发送给RAN节点或N3IWF的网络定位消息、RAN节点或N3IWF返回给AMF的网络定位消息，当然，定位信息还可以是其他信息，在此就不一一列举了，也不做任何限制。
例如，在3GPP接入类型下，为UE服务的AMF为AMF1，在非3GPP接入类型下，为UE服务AMF为AMF2时，若UE在3GPP接入类型内的空闲态即CM-IDLE状态，在非3GPP接入类型处于连接态即CM-CONNECTED状态，GMLC就可以确定非3GPP接入类型用于传输定位信息。若UE在3GPP接入类型内处于CM-CONNECTED状态，在非3GPP接入状态处于CM-IDLE状态，GMLC就可以确定3GPP接入类型用于传输定位信息。
例如，若运营商策略包括：若UE在3GPP接入类型以及非3GPP接入类型中均处于CM-CONNECTED状态时，优先使用3GPP接入类型用于传输定位信息，那么，当GMLC确定UE在3GPP接入类型内以及非3GPP接入类型中均处于CM-CONNECTED状态时，无论在3GPP接入类型下以及非3GPP接入类型下，为UE服务的AMF是否相同，GMLC都可以确定使用3GPP接入类型传输定位信息。
第二种方式：
步骤C：所述GMLC向为所述UE服务的AMF发送第四请求，所述GMLC接收所述为所述UE服务的AMF发送的第二信息。
GMLC也可通过UDM向UE的服务AMF订阅相关事件，因此，GMLC也可通过UDM向UE的服务AMF发送第四请求，以订阅UE状态变化、UE位置变化等事件，当发生相关事件时，AMF直接或通过UDM将相关事件通知给GMLC，使GMLC获得UE使用的所有接入类型，UE在每种接入类型内的状态信息，为UE服务的AMF等信息，GMLC还可以在本地存储获得的相关事件。
那么，GMLC接收到LCS客户端发送的LCS服务请求之后，就可以从本地存储的信息中，获取UE使用的所有接入类型，为UE服务的AMF，以及UE在每种接入类型内的状态信息。GMLC根据获取的上述信息，就可以从UE使用的所有接入类型，即3GPP接入类型和非3GPP接入类型中，确定用于传输定位信息的接入类型。在实际应用中，GMLC还可以结合获得上述信息以及运营商策略决定用于传输定位信息的接入类型，在此就不重复叙述。
在本申请实施例中，GMLC确定用于传输定位信息的接入类型之后，还可以执行以下步骤：
步骤E：所述GMLC确定对于不同接入类型，为所述UE服务的AMF相同；
步骤F：则所述GMLC向所述AMF发送确定的接入类型以及传输定位信息的请求；
步骤G：所述GMLC接收所述AMF发送的UE位置信息。
例如，在GMLC确定使用3GPP接入类型传输定位信息，且GMLC确定对于不同接 入类型，为所述UE服务的AMF相同时，GMLC就会向该AMF发送确定的接入类型以及传输定位信息的请求，传输定位信息的请求可以具体为Provide Location Request消息，GMLC可以通过Provide Location Request消息携带确定的接入类型发送给AMF，AMF在接收到GMLC发送的Provide Location Request消息之后，就会对UE执行3GPP接入类型内的定位过程，从而获得UE的位置信息，AMF将获得的UE位置信息可以通过Provide Location Response消息反馈给GMLC，GMLC接收到该消息之后，将该消息中的UE位置信息反馈给LCS客户端。
在本申请实施例中，在上述步骤F和步骤G，还可以按照以下方式执行：
所述GMLC向所述LMF发送确定的接入类型以及传输定位信息的请求；所述GMLC接收所述LMF发送的UE位置信息。
例如，在GMLC确定使用3GPP接入类型传输定位信息，且GMLC确定对于不同接入类型，为所述UE服务的AMF相同时，且GMLC与LMF之间有接口，GMLC可以向该AMF连接的LMF发送确定的接入类型以及传输定位信息的请求，进而使得LMF接收到GMLC发送的确定的接入类型以及传输定位信息的请求之后，执行3GPP接入类型内的定位过程，获得UE定位信息，LMF将UE定位信息传输给GMLC，GMLC反馈给LCS客户端。
在本申请实施例中，GMLC确定对于不同接入类型，为UE服务的AMF不同时，GMLC向确定的接入类型下，为UE服务的AMF发送传输定位信息的请求，以及GMLC接收所述确定的接入类型下，为UE服务的AMF发送的UE位置信息。
例如，GMLC确定对于不同接入类型，为所述UE服务的AMF不同时，例如，在3GPP接入类型下，为UE服务的AMF为AMF1，在非3GPP接入类型下，为UE服务AMF为AMF2，若GMLC确定用于传输定位信息的接入类型为3GPP接入类型，那么，GMLC就可以向AMF1发送传输定位信息的请求。那么，AMF1在接收到GMLC发送的传输定位信息的请求之后，就会对UE执行3GPP接入类型内的定位过程，从而获得UE的位置信息，AMF1将获得的UE位置信息可以通过Provide Location Response消息反馈给GMLC，GMLC接收到该消息之后，将该消息中的UE位置信息反馈给LCS客户端。
当然，在实际应用中，还可以在GMLC确定对于不同接入类型，为所述UE服务的AMF不同时，GMLC可以向确定的接入类型下、为UE服务的AMF连接的LMF，发送传输定位信息的请求，以及GMLC接收LMF发送的UE位置信息。
在本申请实施例中，在UE漫游时，本申请实施例中图8所示的方法还可以按照以下流程具体实现：
步骤H：H-GMLC接收LCS客户端发送的第二请求；
步骤L：所述H-GMLC获取第三信息，所述第三信息包括以下信息中的至少一种：所述UE使用的所有接入类型，为所述UE服务的AMF，以及所述UE在所述每种接入类型内的状态信息；
步骤M：所述H-GMLC向V-GMLC发送所述第三信息；
步骤N：所述V-GMLC根据所述第三信息，从所有接入类型中，确定用于传输定位信息的接入类型。
在具体实践过程中，当UE漫游时，GMLC又可分为H-GMLC(Home-GMLC)以及V-GMLC(Visited-GMLC)，H-GMLC是位于UE的家乡网络(如HPLMN)内的GMLC， V-GMLC是位于UE漫游到的拜访网络(如VPLMN)的GMLC，那么，LCS客户端可以向H-GMLC发送LCS服务请求，LCS服务请求就为步骤H中的第二请求，同样的，LCS服务请求中可以携带UE的标识符，H-GMLC接收到LCS服务请求之后，就可以如上文叙述的第一种方式或第二种方式获取到第三消息(即上文中的第二消息)，在此，就不重复叙述。
H-GMLC将获取到的第三消息发送给V-GMLC，即将UE使用的所有接入类型，为UE服务的AMF，以及UE在每种接入类型内的状态信息发送给V-GMLC，V-GMLC就可以根据第三消息，从UE使用的所有接入类型，即3GPP接入类型和非3GPP接入类型中，确定用于传输定位信息的接入类型。同样的，在实际应用中，V-GMLC还可以结合获得上述第三信息以及运营商策略决定用于传输定位信息的接入类型，其中，在实际应用中，上述第三消息可以具体为LCS Service Request消息，也可以为Location Request消息，当然，还可以为其他消息，在此就不一一列举。
V-GMLC在确定用于传输定位信息的接入类型之后，还可以向为UE服务的AMF发送确定的接入类型，当然还可以发送传输定位信息的请求，传输定位信息的请求可以为Provide Location Request消息，也可以为Namf_Location_ProvideLocation_Request消息，还可以为其他消息，在此，也不一一列举，并以传输定位信息的请求具体为Provide Location Request消息为例，那么，V-GMLC可以通过Provide Location Request消息携带确定的接入类型发送给为UE服务的AMF，该AMF在接收到V-GMLC发送的Provide Location Request消息之后，就可以根据Provide Location Request消息中携带的接入类型，对UE执行该接入类型内的定位过程，从而获得UE的位置信息，AMF将获得的UE位置信息可以通过Provide Location Response消息或Namf_Location_ProvideLocation_Response消息或其他消息反馈给V-GMLC，进而使得V-GMLC向H-GMLC返回携带了UE的位置信息的LCS Service Response或Location Response或其他消息，并通过H-GMLC将LCS Service Response或Location Response或其他消息中的UE位置信息反馈给LCS客户端，在此就不重复叙述，具体过程可参见上文的叙述。
当然，在实际应用中，当V-GMLC与LMF之间有接口时，V-GMLC可以向LMF发送确定的接入类型以及传输定位信息的请求，传输定位信息的请求可以具体为Provide Location Request消息，V-GMLC可以通过Provide Location Request消息携带确定的接入类型发送给LMF，LMF根据Provide Location Request消息中携带的接入类型，对UE执行该接入类型内的定位过程，获得UE定位信息，LMF将UE定位信息传输给V-GMLC，V-GMLC反馈给H-GMLC，进而通过H-GMLC将UE位置信息反馈给LCS客户端，在此就不重复叙述，具体过程可参见上文的叙述。
所以，通过上述方法，GMLC在接收到LCS客户端发送的第二请求，由GMLC确定用于传输定位信息的接入类型，不仅能够适用于UE在不同接入类型下，为UE服务的AMF不同的场景下的UE的定位服务，也适用于UE在不同接入类型下，为UE服务的AMF相同的场景下的UE的定位服务，所以，有效的解决了现有技术中，在3GPP接入类型以及非3GPP接入类型接入下，为UE服务的AMF不同时，存在不能实现对UE的定位服务的技术问题。
实施例三
本申请实施例还提供了另一种接入类型选择方法，该方法包括以下步骤：
步骤O：LMF接收GMLC发送的第三请求；
步骤P：所述LMF确定用于传输定位信息的接入类型。
本申请实施例三中的接入类型的选择方法，也可应用于UE同时通过3GPP接入类型和非3GPP(non-3GPP)接入类型连接至核心网的应用场景，在该应用场景下，当LCS客户端需要获得UE的位置信息时，可以向GMLC发送LCS服务请求，LCS服务请求中携带UE的标识符，在实际应用中，LCS服务请求可以具体为LCS Service Request消息，在该LCS Service Request消息中携带UE的标识符。
GMLC接收到LCS客户端发送的LCS服务请求之后，可以如实施例二中所述的第一种方式或第二种方式获取UE使用的所有接入类型，也可以获取为UE服务的AMF，还可以获取UE在每种接入类型内的状态信息，这里为了叙述方便，将GMLC获取的UE使用的所有接入类型、为UE服务的AMF、UE在每种接入类型内的状态信息统称为第四信息。
GMLC将获取的第四信息通过第三请求发送给LMF，在实际应用中，第三请求可以为Provide Location Request消息，也可以为Nlmf_ProvideLocation_Request消息，还可以为其他消息，在此就不一一例举了，并以第三请求具体为Nlmf_ProvideLocation_Request消息为例，那么，LMF在接收到GMLC发送的Nlmf_ProvideLocation_Request消息之后，就可以根据Nlmf_ProvideLocation_Request消息中携带的第四信息，即UE使用的所有接入类型、为UE服务的AMF、UE在每种接入类型内的状态信息，从所有接入类型中，确定用于传输定位信息的接入类型。同样的，在实际应用中，LMF还可以结合第四信息以及运营商策略决定用于传输定位信息的接入类型。在此，就不重复叙述。
同样的，定位信息可以是UE的位置，如地理位置、城市位置(如UE所在的街道、城市)等，还可以是获取UE位置的时间信息，也可以是获取UE位置使用的定位方法、定位精度等与定位相关的信息，还可以是与执行定位相关的消息，如AMF发送给RAN节点或N3IWF的网络定位消息、RAN节点或N3IWF返回给AMF的网络定位消息，当然，定位信息还可以是其他信息，在此就不一一列举了，也不做任何限制。
在LMF确定用于传输定位信息的接入类型之后，还可以将确定的接入类型发送给为UE服务的AMF，进而使得该AMF执行该接入类型内的定位过程，例如，LMF确定用于传输定位信息的接入类型为非3GPP接入类型时，LMF将非3GPP接入类型发送给为UE服务的AMF，当然，LMF还可以同时发送提供UE位置的定位请求信息如DL Positioning消息或网络定位消息或其他消息，那么，AMF在接收到非3GPP接入类型之后，就可以使用非3GPP接入类型内的定位过程，从而获得UE的位置信息，AMF将获得的UE位置信息反馈给LMF，进而由LMF通过Provide Location Response消息或Nlmf_ProvideLocation_Response消息或其他消息携带UE的位置信息反馈给GMLC，GMLC接收到携带UE的位置信息的消息之后，将该消息中的UE位置信息反馈给LCS客户端。
所以，通过上述方法，LMF在接收到GMLC发送的第三请求，由LMF确定用于传输定位信息的接入类型，不仅能够适用于UE在不同接入类型下，为UE服务的AMF不同的场景下的UE的定位服务，也适用于UE在不同接入类型下，为UE服务的AMF相同的场景下的UE的定位服务，所以，有效的解决了现有技术中，在3GPP接入类型以及非3GPP接入类型接入下，为UE服务的AMF不同时，存在不能实现对UE的定位服务的技术问题。
