具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
本申请实施例提供的网络接入方式确定方法，可以适用于如图1所示的网络接入方式确定系统，网络接入方式确定系统包括核心网、远端用户设备(即远端UE)和多个中继用户设备(即中继UE)，图1中仅示出了1个中继UE。可选地，核心网可以为2G、3G、4G等核心网，在本申请实施例中，核心网可以为5G核心网，即5GC。核心网中可以包括统一数据管理功能(Unified Data Management，UDM)网元、接入和移动管理功能(Access and Mobility Management Function，AMF)网元、统一数据仓库功能(Unified Data Repository，UDR)网元、策略控制功能(Policy Control Function，PCF)网元、会话管理功能(Session Management Function，SMF)网元、非第三代合作伙伴计划互通功能(Non-3GPP InterWorking Function，N3IWF)网元、用户平面功能(User plane function，UPF)网元等。其中，核心网中的接入和移动管理功能网元和会话管理功能网元均可以与远端用户设备间接通信。这里需要说明的是，上述3GPP表示第三代合作伙伴计划。
在本申请实施例中，远端用户设备通过中继用户设备与非第三代合作伙伴计划互通功能网元通信，因此，图1将非第三代合作伙伴计划互通功能网元在5G核心网外为例示意。同时，核心网中的用户平面功能网元可以与数据网通信，因此，图1中的用户平面功能网元也在5G核心网外示意。另外，在整体网络架构中，与核心网连接的对象还可以包括无线接入网(NG-RAN)节点和数据网(Data Network)，其中，普通用户设备可以通过NG-RAN节点与核心网中的用户平面功能网元通信。
图1中的实线表示通信连接线，PC5、Uu、N2、N3、N4和N6均表示实线两端的通信对象之间的通信接口。图1中PLMN A和PLMN B分别表示不同的公共陆地移动网(PublicL and Mobile Network，PLMN)，图1中的非第三代合作伙伴计划互通功能网元与用户平面功能网元的左侧架构通过PLMN B进行通信，非第三代合作伙伴计划互通功能网元与用户平面功能网元的右侧架构通过PLMN A进行通信。可以理解，术语“左侧”，“右侧”指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
上述远端用户设备和中继用户设备均可以但不限于是各种个人计算机、笔记本电脑、智能手机和平板电脑，本实施例对远端用户设备和中继用户设备的具体形式不做限定。下述实施例中将具体介绍网络接入方式确定方法的具体过程，并且以执行主体为接入和移动管理功能网元、会话管理功能网元或远端用户设备来介绍网络接入方式确定方法的具体过程。
图2为本申请实施例提供的网络接入方式确定方法的流程示意图，应用于接入和移动性管理功能网元，该方法可以包括以下步骤：
S101、根据非第三代合作伙伴计划互通功能网元发送的业务控制消息，获取中继用户设备的位置信息。其中，中继用户设备用于实现远端用户设备与非第三代合作伙伴计划互通功能网元之间进行通信。
这里需要说明的是，中继用户设备可以是远端用户设备从多个候选中继用户设备中选取的任一个候选中继用户设备。可选地，候选中继用户设备可以为层2(也称数据链路层)用户设备到核心网功能 的中继用户设备、支持非第三代合作伙伴计划互通功能接入的层3(也称网络层)用户设备到核心网功能的中继用户设备、或者不支持非第三代合作伙伴计划互通功能接入的层3用户设备到核心网功能的中继用户设备等。在本申请实施例中，为了使得上述方法不仅能够适用于2G、3G、4G或5G的场景下，即为了提高网络接入方式确定方法的广泛适用性，中继用户设备可以为支持非第三代合作伙伴计划互通功能5G接入的层3用户设备到核心网功能的中继用户设备。
一个实施例中，中继用户设备是远端用户设备在邻近业务(Proximity-based Services，ProSe)功能授权成功的情况下，从多个候选中继用户设备中确定的任一个候选中继用户设备，每个候选中继用户设备表示在核心网中已成功授权邻近业务功能的候选中继用户设备。
在实际应用中，远端用户设备可以向核心网发送通信系统注册请求，以指示核心网中的接入和移动管理功能网元、策略控制功能网元、会话管理功能网元和统一数据管理功能网元等共同执行，根据通信系统注册请求中携带的通信系统注册信息，对远端用户设备的通信系统进行注册，也就是对远端用户设备的邻近业务功能进行授权，在授权成功后，核心网可以向远端用户设备发送第一中继服务信息。可选地，上述通信系统可以为2G系统、3G系统、4G系统等，在本申请实施例中，该通信系统可以为5G系统。
并且，各候选中继用户设备也可以向核心网发送通信系统注册请求，以指示核心网中的接入和移动管理功能网元、策略控制功能网元、会话管理功能网元和统一数据管理功能网元等共同执行，根据通信系统注册请求中携带的通信系统注册信息，对各候选中继用户设备的通信系统进行注册，也就是对各候选中继用户设备的邻近业务功能进行授权，在授权成功后，核心网可以向各候选中继用户设备发送第二中继服务信息。
进一步，远端用户设备可以从各候选中继用户设备处或者核心网获取各候选中继用户设备的第二中继服务信息，然后将与第一中继服务信息匹配的第二中继服务信息对应的候选中继用户设备，确定为中继用户设备。
在实际应用中，远端用户设备通过中继用户设备与核心网中的非第三代合作伙伴计划互通功能网元通信后，可以将业务控制消息通过中继用户设备发送给非第三代合作伙伴计划互通功能网元，非第三代合作伙伴计划互通功能网元在接收到业务控制消息后，将业务控制消息发送给核心网中的接入和移动管理功能网元。
对应地，接入和移动管理功能网元可以接收非第三代合作伙伴计划互通功能网元发送的业务控制消息，并且在接收到业务控制消息后，可以根据发送业务控制消息时采用的中继用户设备，获取中继用户设备的位置信息。
其中，业务控制消息可以理解为非第三代合作伙伴计划互通功能网元控制核心网中的其它网元执行业务处理的消息。该业务控制消息可以包括数据信息、控制信令等。
示例性地，业务控制消息可以为上行非接入层(Non-Access Stratum，NAS)消息等，还可以为N2口、N3口或N4口信令等。
在本申请实施例中，接入和移动管理功能网元可以根据非第三代合作伙伴计划互通功能网元发送的业务控制消息，进一步获取中继用户设备的位置信息。可选地，中继用户设备的位置信息可以表示为中继用户设备的平面位置坐标或空间位置坐标，还可以为中继用户设备的经纬度坐标，当然，还可以表示为其它形式。
一实施例中，获取中继用户设备的位置信息的方式可以是非第三代合作伙伴计划互通功能网元发送业务控制消息后主动发送给接入和移动管理功能网元的。
又一实施例中，获取中继用户设备的位置信息的方式还可以是接入和移动管理功能网元向非第三代合作伙伴计划互通功能网元发送位置信息获取请求，对应地，非第三代合作伙伴计划互通功能网元响应位置信息获取请求后，将中继用户设备的位置信息发送给接入和移动管理功能网元。
这里需要说明的是，非第三代合作伙伴计划互通功能网元可以在不同候选中继用户设备标识与不同候选中继用户设备位置信息之间的对应关系中，查找与发送业务控制消息时采用的中继用户设备标识对应的候选中继用户设备标识，然后将查找到的候选中继用户设备标识对应的候选中继用户设备位置信息，确定为中继用户设备的位置信息。
一个实施例中，业务控制消息为远端用户设备与非第三代合作伙伴计划互通功能网元建立通信隧道后，远端用户设备通过通信隧道经过中继用户设备发送至非第三代合作伙伴计划互通功能网元的。
在本申请实施例中，通信隧道可以为信令互联网协议安全(Internet Protocol Security，IPsec)隧道。其中，远端用户设备将业务控制消息通过通信隧道经过中继用户设备发送至非第三代合作伙伴计划互通功能网元，可以理解为远端用户设备直接将业务控制消息通过通信隧道发给非第三代合作伙伴计划互通功能网元，中继用户设备不会接收到业务控制消息，但业务控制消息发送过程中的通信信号会经过中继用户设备。
S102、基于所述中继用户设备的位置信息，确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式。
其中，网络接入方式可以理解为远端用户设备与非第三代合作伙伴计划互通功能网元的网络通信方式。可选地，网络接入方式可以为通用分组无线接入方式、宽带码分多址无线接入方式、无线局域网接入方式、码分多址接入方式或邻近业务接入方式等。
具体地，根据中继用户设备的位置信息，确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式的方法可以是接入和移动管理功能网元直接对中继用户设备的位置信息进行处理，得到远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式。
在实际应用中，根据中继用户设备的位置信息，确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式的方法还可以是接入和移动管理功能网元将中继用户设备的位置信息发送给核心网中的会话管理功能网元，然后会话管理功能网元对中继用户设备的位置信息进行处理，得到远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式。
一种实现方式中，对中继用户设备的位置信息进行处理得到远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式的方法，可以是根据中继用户设备的位置信息、远端用户设备的位置信息和非第三代合作伙伴计划互通功能网元的位置信息，采用距离法计算中继用户设备与远端用户设备之间的距离以及中继用户设备与非第三代合作伙伴计划互通功能网元之间的距离，然后根据中继用户设备与远端用户设备之间的距离大小以及中继用户设备与非第三代合作伙伴计划互通功能网元之间的距离大小，确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式。
另一种实现方式中，对中继用户设备的位置信息进行处理得到远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式的方法，还可以是从不同网络接入区域标识与不同中继用户设备位置信息之间的对应关系中，查找与中继用户设备的位置信息匹配的中继用户设备位置信息对应的网络接入区域标识，并将该网络接入区域标识对应的网络接入方式确定为远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式。
可选地，网络接入区域标识可以理解为非第三代合作伙伴计划互通功能网元可接入不同网络的服务区域的标识。
在本申请实施例中，确定出远端用户设备的网络接入方式为邻近服务接入方式后，可以进一步触发会话管理功能网元后续对其它信息发送过程中产生的不同网络流量进行成功区分管理，以解决传统技术中无法实现不同流量区别管理的问题，并且在能够实现对不同流量进行区别管理的基础上，进一步可以方便核心网对不同流量进行差异化计费，以及核心网对远端用户设备进行业务管理和策略控制。
其中，上述其它信息的发送指的是远端用户设备将其它信息发送至非第三代合作伙伴计划互通功能网元的过程，其它信息也可以为数据信息、控制信令等。
这里需要说明的是，后续对其它信息发送过程中产生的不同网络流量进行管理可以理解为在远端用户设备通过中继用户设备接入非第三代合作伙伴计划互通功能网元时，对其它信息发送过程中使用的邻近业务流量和普通流量进行区分管理的过程。
其中，用ProSe表示邻近业务时，上述邻近业务流量可以包括远端用户设备向非第三代合作伙伴计划互通功能网元发送其它信息所使用的ProSe流量、以及远端用户设备向非第三代合作伙伴计划互通功能网元发送其它信息过程中中继用户设备贡献的ProSe流量。普通流量可以包括远端用户设备向非第三代合作伙伴计划互通功能网元发送其它信息过程中，中继用户设备通过非ProSe接入非第三代合作伙伴计划互通功能网元所使用的流量。
在实际应用中，若接入和移动管理功能网元确定出网络接入方式为邻近业务接入方式后，接入和移动管理功能网元可以触发会话管理功能网元后续对其它信息发送过程中产生的不同网络流量进行管理；若会话管理功能网元确定出网络接入方式为邻近业务接入方式后，会话管理功能网元可以自主触发后续对其它信息发送过程中产生的不同网络流量进行管理。
另外，上述网络流量管理可以包括对不同类型的网络流量进行细粒度统计、分析和/或存储等处理，其中，根据不同网络流量统计结果还可以方便核心网对不同流量进行差异化计费，以及核心网对远端用户设备进行业务管理和策略控制。
本申请实施例中的技术方案，根据非第三代合作伙伴计划互通功能网元发送的业务控制消息，获取中继用户设备的位置信息，并基于位置信息，确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式，其中，中继用户设备用于实现远端用户设备与非第三代合作伙伴计划互通功能网元之间进行通信。上述方法通过获取到的中继用户设备的位置信息，能够成功确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式；进一步地，在确定出远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式的基础上，可以触发核心网后续对不同网络流量进行成功区分管理，从而能够提高网络接入方式确定方法的广泛使用性。
下面对上述基于位置信息，确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式的过程进行说明。在一实施例中，如图3所示，上述S102中的步骤，可以通过以下方式实现：
S112、获取中继用户设备的接入网络类型。
在实际应用中，非第三代合作伙伴计划互通功能网元接收到业务控制消息后，可以获取中继用户设备的接入网络类型。进一步，可以将中继用户设备的接入网络类型主动发送给接入和移动管理功能网元。
另外，接入和移动管理功能网元还可以向非第三代合作伙伴计划互通功能网元发送接入网络类型获取请求，非第三代合作伙伴计划互通功能网元响应接入网络类型获取请求后，将中继用户设备的接入网络类型发送给接入和移动管理功能网元。
相应地，接入和移动管理功能网元可以接收非第三代合作伙伴计划互通功能网元发送的中继用户设备的接入网络类型。
S122、在接入网络类型为非第三代合作伙伴计划接入类型的情况下，根据中继用户设备的位置信息，确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式。
可选地，接入网络类型可以包括第三代合作伙伴计划接入类型和非第三代合作伙伴计划接入类型等，对此本申请实施例不做限定。在本申请实施例中，为了减少网络接入方式确定过程中的数据处理量，提高网络接入方式的确定速度，可以先初步判断接入网络类型是否为非第三代合作伙伴计划接入类型。
具体地，接入和移动管理功能网元在获取到中继用户设备的接入网络类型后，可以初步判断接入网络类型是否为非第三代合作伙伴计划接入类型，在确定接入网络类型为非第三代合作伙伴计划接入类型的情况下，进一步再对中继用户设备的位置信息进行处理，得到接入网络类型对应的网络接入方式，即远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式。
进一步，在实际应用中，流量管理操作是核心网中的会话管理功能网元执行的，下面对如何触发会话管理功能网元执行流量管理操作的过程进行说明。在一实施例中，在接入和移动性管理功能网元获取到网络接入方式的步骤之后，上述方法还可以包括：在网络接入方式为邻近业务接入方式的情况下，向会话管理功能网元发送流量管理请求，以指示会话管理功能网元对网络流量进行管理。
可选地，流量管理请求可以包括网络接入方式为邻近业务接入方式的相关信息。
在本申请实施例中，若接入和移动管理功能网元已经确定网络接入方式为邻近业务接入方式，此时，会话管理功能网元响应流量管理请求后，可以后续对其它信息发送过程中产生的不同网络流量进行成功区分管理。
这里需要说明的是，为了减少网络接入方式确定过程中的数据处理量，提高网络接入方式的确定速度，接入和移动管理功能网元在执行根据中继用户设备的位置信息，确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式的步骤之前，可以先根据远端用户设备的标识，判断远端用户设备是否位于中继用户设备提供的用户设备通信范围内，若是，则执行根据中继用户设备的位置信息，确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式的步骤。
其中，远端用户设备在中继用户设备提供的用户设备通信范围外时，远端用户设备与中继用户设备是无法通信的，此时，确定的网络接入方式不准确。
本申请实施例中的技术方案，获取中继用户设备的接入网络类型，并在接入网络类型为非第三代合作伙伴计划接入类型的情况下，根据中继用户设备的位置信息，确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式；在中继用户设备的接入网络类型为非第三代合作伙伴计划接入类型的情况下，该方法可以根据中继用户设备的位置信息确定非第三代合作伙伴计划接入类型对应的网络接入方式，根据确定出的网络接入方式，可以提高网络接入方式确定方法的广泛使用性。
下面对上述根据中继用户设备的位置信息，确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式的过程进行说明。在一实施例中，如图4所示，上述S122中根据中继用户设备的位置信息，确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式的步骤，可以通过以下方式实现：
S1221、根据中继用户设备的位置信息，获取中继用户设备的网络协议地址。
其中，中继用户设备的网络协议地址可以表示中继用户设备的IP地址。
具体地，接入和移动管理功能网元可以是直接对中继用户设备的位置信息进行处理，得到中继用户设备的网络协议地址。
一实施例中，对中继用户设备的位置信息进行处理得到中继用户设备的网络协议地址的方式，可以是预先训练一种算法模型，然后将中继用户设备的位置信息输入至算法模型中，算法模型输出中继用户设备的网络协议地址。
又一实施例中，对中继用户设备的位置信息进行处理得到中继用户设备的网络协议地址的方式，还可以是对中继用户设备的位置信息进行转换处理，得到中继用户设备的网络协议地址。
一个实施例中，上述S1221中的步骤，可以包括：根据预设的位置地址关联关系，获取与中继用户设备的位置信息关联的网络协议地址，作为中继用户设备的网络协议地址。其中，位置地址关联关系包括多个不同中继用户设备的位置信息与关联的网络协议地址之间的对应关系。
在本申请实施例中，位置地址关联关系可以包括多个不同中继用户设备的位置信息与关联的网络协议地址之间的对应关系。
具体地，可以在位置地址关联关系中，查找与中继用户设备的位置信息关联的网络协议地址，并将查找到的网络协议地址确定为中继用户设备的网络协议地址。
S1222、若网络协议地址池中存在中继用户设备的网络协议地址，则确定网络接入方式为邻近业务接入方式；或者，若网络协议地址池中不存在中继用户设备的网络协议地址，则确定网络接入方式为非邻近业务接入方式。
可选地，网络协议地址池可以是预先配置的，网络协议地址池中可以包括通过邻近业务接入非第三代合作伙伴计划互通功能网元的不同候选中继用户设备的网络协议地址。
进一步，基于获取到的中继用户设备的网络协议地址，可以判断网络协议地址池中是否存在中继用户设备的网络协议地址，若存在，则确定接入网络类型为邻近业务接入，即网络接入方式为邻近业务接入方式。
其中，在确定网络协议地址池中不存在中继用户设备的网络协议地址时，确定接入网络类型为非邻近业务接入方式，即网络接入方式为非邻近业务接入方式。
本申请实施例中的技术方案，根据中继用户设备的位置信息，获取中继用户设备的网络协议地址，若网络协议地址池中存在中继用户设备的网络协议地址，则确定网络接入方式为邻近业务接入方式，若网络协议地址池中不存在中继用户设备的网络协议地址，则确定网络接入方式为非邻近业务接入方式。该方法可以通过中继用户设备的位置信息确定网络接入方式是否为邻近业务接入方式，以为进一步成功触发流量管理操作做准备，从而能够提升流量管理的可实现性。
在一些场景中，确定网络接入方式的过程是核心网中的会话管理功能网元执行的，下面对接入和移动性管理功能网元如何控制会话管理功能网元确定网络接入方式的过程进行说明。在一实施例中，如图5所示，上述S102中基于位置信息获取远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式的步骤，可以包括：
S132、获取中继用户设备的接入网络类型。
其中，步骤S132中获取中继用户设备的接入网络类型的方式，与上述步骤S112中获取中继用户设备的接入网络类型的方式相同，对此本申请实施例不再赘述。
S142、向会话管理功能网元发送位置信息和接入网络类型，指示会话管理功能网元在接入网络类型为非第三代合作伙伴计划接入类型的情况下，根据中继用户设备的位置信息，确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式。
在实际应用中，接入和移动管理功能网元获取到中继用户设备的位置信息和接入网络类型后，可以将位置信息和接入网络类型均发送至会话管理功能网元。
对应地，会话管理功能网元接收到位置信息和接入网络类型后，可以初步判断接入网络类型是否为非第三代合作伙伴计划接入类型，在确定接入网络类型为非第三代合作伙伴计划接入类型的情况下，进一步再对中继用户设备的位置信息进行处理，得到远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式。

一种实施例中，本申请实施例还提供一种网络接入方式确定方法，应用于接入和移动性管理功能网元，该方法包括以下过程：

S11、基于位置信息确定远端用户设备接入非第三代合作伙伴计划互通功能网元的网络接入方式。
其中，S11中步骤的实现方式可以包括两种：
第一种方式，可以包括：
