目前，3GPP正在研究非地面网络(non terrestrial network，NTN)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，卫星通信是指利用人造地球卫星作为中继站，转发或反射无线电波，在两个或多个地球站之间进行的通信。
与地面网络通信相比，卫星网络通信具有如下优点：
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。
因而，在NTN中，通过将基站或者部分基站功能部署在高空平台或者卫星上为终端设备提供无缝覆盖，并且高空平台或者卫星受自然灾害影响较小，能提升5G系统的可靠性。
在卫星的应用中，根据提供服务的通信卫星所在的轨道高度，通信卫星可分为地球同步轨道(geostationary earth orbit，GEO)卫星和非地球同步轨道(Non-GEO)卫星。其中，非地球同步轨道卫星又可以分为低地球轨道(low earth orbit，LEO)卫星、中地球轨道(medium-earth orbit，MEO)卫星和高椭圆轨道(high elliptical orbit，HEO)卫星等。其中，LEO卫星的轨道高度范围为500km～1500km，MEO卫星的轨道高度范围为2000～20000km，HEO卫星距离地球表面的最近点为1000～21000km，最远点为39500～50600km，GEO卫星的轨道高度为35786km。
通常情况下，为了保证卫星的覆盖范围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。
在无线通信中，可采用邻近业务(proximity services，ProSe)技术使小区覆盖范围外的用户设备UE通过小区覆盖范围内的UE与基站进行通信，提高数据的传输效率。其中，小区覆盖范围外的UE被称为远端UE，小区覆盖范围内的UE被称为中继UE(relay UE)，如图1所示。远端UE利用ProSe技术中的发现过程，确定中继UE，并与中继UE建立连接与通信，远端UE通过中继UE接入网络，中继UE用于传输远端UE与网络之间的数据。
图2为本申请实施例提供的一种场景示意图，如图2所示，具有ProSe能力的远端UE可以通过PC5接口与具有ProSe能力的中继UE建立直接通信，其中，中继UE可采用卫星网络接入5G核心网CN。也就是说，图2中的远端UE可通过采用卫星网络接入方式的中继UE与5G网络建立PDU会话，实现远端UE与外部数据网络的交互。
本申请实施例中，根据卫星所处轨道的不同，中继UE的网络接入方式可分为：NR-LEO接入，NR-MEO接入，NR-GEO接入以及NR-OTHERSAT(其他卫星)接入等。
在卫星网络中，尤其在GEO卫星网络中，UE与卫星之间以及卫星与地面站之间的距离过大，导致了UE与数据网络之间的延迟较大。在一些业务中，例如车联网V2X(vehicle to everything)业务不适合在卫星网络中使用。因此，远端UE在通过中继设备连接网络时，可能存在如下问题：如果远端UE不知道中继设备当前正处于卫星网络下(即中继设备当前采用卫星接入网络)，而选择该中继设备与核心网建立PDU会话，会导致一些与NTN不支持的业务相关的PDU会话被核心网拒绝，既浪费信令又导致会话请求的失败。
针对上述问题，本申请实施例提出一种数据传输方法，网络侧可为终端设备接入网络的方式(接入类型)进行预配置，终端设备可根据预配置信息生成指示信息，以告知其他设备其网络接入方式。对于需要建立网络连接的远端设备，可通过发送指示信息，使得周围设备获知其允许的网络接入方式。对于中继设备，也可通过发送指示信息，使得远端设备提前获知其周围的中继设备的网络接入情况，从而选择合适的中继设备建立网络连接。通过上述数据传输方案，可避免远端设备通过接入卫星网络的中继设备连接网络而导致数据延迟严重的问题，以及由于中继设备接入的网络不支持远端设备的业务而导致网络连接失败的问题。
本申请提出的上述数据传输方案包括如下两种具体实现：
1、通过远端设备的发现过程，进行终端设备之间网络接入方式的指示。
2、通过远端设备的连接建立过程，进行终端设备之间网络接入方式的指示。
下面，通过具体实施例对本申请所示的技术方案进行详细说明。需要说明的是，下面几个实施例可以单独存在也可以相互结合。对于相同或相似的内容，例如，术语或名词的解释说明，及步骤的解释说明等，在不同的实施例中可以相互参考，不再重复说明。
结合图3至图8实施例所示的数据传输方法，对通信系统中位于网络覆盖范围之外的远端设备如何通过中继设备接入网络的技术方案进行详细描述。
图3为本申请实施例提供的一种数据传输方法的交互示意图。如图3所示，本实施例提供的方法包括如下步骤：
步骤101、中继设备向远端设备发送第一指示信息，第一指示信息用于指示中继设备的网络接入方式。
本实施例中，中继设备的网络接入方式包括地面网络(terrestrial network，TN)接入或者卫星网络(non-terrestrial network，NTN)接入。其中，NTN的接入方式包括NR-LEO接入，NR-MEO接入，NR-GEO接入以及NR-OTHERSAT接入。
在本申请的一个实施例中，第一指示信息可直接指示中继设备的网络接入方式。
在本申请的一个实施例中，第一指示信息包括中继业务代码(relay service code，RSC)。其中，RSC与中继设备的网络接入方式相对应，和/或，RSC与采用卫星接入网络的时延信息相对应。
步骤102、远端设备根据第一指示信息确定是否通过中继设备建立网络连接。
在本申请的一个实施例中，远端设备根据第一指示信息指示的中继设备的网络接入方式以及远端设备传输数据的业务类型，确定是否通过中继设备建立网络连接。
具体的，若第一指示信息指示的中继设备的网络接入方式支持远端设备传输数据的业务类型，则远端设备确定通过该中继设备建立网络连接。若第一指示信息指示的中继设备的网络接入方式不支持远端设备传输数据的业务类型，则远端设备确定不通过该中继设备建立网络连接，可选择其他中继设备建立网络连接。
示例性的，假设第一指示信息指示的中继设备采用同步轨道卫星GEO接入网络，如果远端设备想要建立的数据业务，例如车联网V2X业务，不适合在卫星网络中使用，远端设备不选择该中继设备。
本实施例提供的数据传输方法，远端设备通过接收来自中继设备的第一指示信息，第一指示信息用于指示中继设备的网络接入方式，远端设备根据第一指示信息确定是否通过中继设备建立网络连接，可以避免远端设备通过接入卫星网络的中继设备连接网络而导致数据延迟严重的问题，还可以避免由于中继设备接入的网络不支持远端设备的业务而导致网络连接失败的问题。通过上述方案可节省不必要的信令交互，实现远端设备快速接入网络。
上述实施例中，远端设备根据中继设备的第一指示信息，确定是否可以通过该中继设备接入网络，其中第一指示信息可以包括RSC，远端设备可通过RSC确定中继设备的网络接入方式。具体的，远端设备可根据预存的中继设备的相关配置信息以及第一指示信息中的RSC，获知中继设备当前的网络接入方式。下面结合附图4对网络侧针对中继设备的相关配置进行介绍。
图4为本申请实施例提供的一种数据传输方法的交互示意图。如图4所示，本实施例提供的方法包括如下步骤：
步骤201、中继设备向网络设备发送中继能力信息。(可选)
步骤202、网络设备根据中继能力信息，生成配置信息。(可选)
步骤203、网络设备向远端设备发送配置信息。
步骤204、网络设备向中继设备发送配置信息。
在本申请的一个实施例中，网络设备可以是PCF网元。
本实施例中，网络设备发送的配置信息包括中继业务代码RSC与中继设备的网络接入方式的对应关系，RSC与中继设备采用卫星接入网络的时延信息的对应关系的至少一项，以及RSC。具体的，
在本申请的一个实施例中，配置信息中可以配置每一种网络接入方式对应的RSC，不同的RSC对应不同的网络接入方式。
在本申请的一个实施例中，配置信息中可以配置采用每一种卫星(低轨卫星、中轨道卫星、同步轨道卫星或其他卫星)接入网络的时延信息对应的RSC，不同的RSC对应不同的时延信息。应理解，终端设备可以通过RSC获知接入某一中继设备的时延信息，如果时延较大，则不考虑通过该中继设备接入网络。
在本申请的一个实施例中，配置信息中可以同时配置每一种网络接入方式对应的RSC，以及采用每一种卫星接入网络的时延信息对应的RSC，每一个RSC对应一种网络接入方式或者时延信息。
远端设备和中继设备分别接收来自网络设备的配置信息，将配置信息保存于本地。对于远端设备而言，只要中继设备向远端设备发送上述第一指示信息，远端设备可根据保存 于本地的配置信息以及第一指示信息，获知任意中继设备的网络接入方式，从而作为远端设备选择中继设备的一个条件。
步骤203和步骤204的执行顺序仅作为一种示例，还可以先执行步骤204再执行步骤203，或者两个步骤同时执行。
可选的，在一些实施例中，网络设备向中继设备和远端设备发送配置信息之前，可接收中继设备发送的中继能力信息。中继能力信息用于指示中继设备支持的网络接入方式，例如中继能力信息指示中继设备支持TN以及NTN接入，或者指示中继设备仅支持NTN接入，或者指示中继设备仅支持TN接入。网络设备根据接收到的中继设备的中继能力信息，生成配置信息。
在一些实施例中，网络设备根据接收到的多个中继设备的中继能力信息，获知中继设备的网络接入方式有哪些，例如包括TN以及NTN接入，NTN接入又分为NR-LEO，NR-GEO，NR-MEO以及NR-OTHERSAT。网络设备对中继设备的上述网络接入方式配置相应的中继业务代码RSC，将配置的RSC以及RSC与中继设备的网络接入方式的对应关系发送给中继设备和远端设备。
在一些实施例中，网络设备根据接收到的多个中继设备的中继能力信息，获知通过中继设备接入网络的时延信息，中继设备接入网络的时延信息间接指示了中继设备的网络接入方式。应理解，采用NTN接入网络的时延信息较大，采用不同轨道卫星接入网络的时延信息存在差异。网络设备对中继设备的上述时延信息配置相应的RSC，将配置的RSC以及RSC与中继设备采用卫星接入网络的时延信息的对应关系发送给中继设备和远端设备。
基于上述实施例公开的网络侧的配置信息，对于中继设备来说，中继设备可根据该配置信息生成第一指示信息，用于指示中继设备当前的网络接入方式和/或网络接入的时延信息。对于远端设备来说，远端设备可根据该配置信息以及中继设备发送的第一指示信息，确定是否可以通过该中继设备接入网络。如果该中继设备采用卫星接入网络，而卫星网络暂不支持远端设备待传输数据的业务类型，那么远端设备可以考虑其他中继设备，从而避免不必要的信令交互。

在本实施例中，中继设备向远端设备发送发现响应，包括：满足第二指示信息指示的网络接入方式的中继设备，向远端设备发送发现响应。远端设备根据该发现响应建立相应的网络连接，即通过该中继设备接入网络。
在本申请的一个实施例中，如果远端设备仅接收到一个中继设备返回的发现响应，可根据该发现响应的第一指示信息确定是否通过该中继设备建立网络连接。
在本申请的一个实施例中，如果远端设备接收到多个中继设备返回的发现响应，可根据接收到的多个发现响应，确定通过哪一个中继设备建立网络连接。
可选的，在一些实施例中，满足第二指示信息指示的网络接入方式的中继设备，可以在发送的发现响应中携带第一指示信息，第一指示信息用于指示中继设备当前的网络接入方式。
本实施例提供的数据传输方法，远端设备在向中继设备广播的发现请求中携带第二指示信息，指示远端设备允许的中继设备的网络接入方式。中继设备向远端设备返回发现响应，发现响应中携带第一指示信息，指示中继设备当前的网络接入方式。远端设备根据发现响应确定是否通过该中继设备接入网络。通过上述方案可节省不必要的信令交互，实现远端设备快速接入网络。
图7为本申请实施例提供的一种数据传输方法的交互示意图。如图7所示，本实施例提供的方法包括如下步骤：
步骤501、远端设备向中继设备广播发现请求。
在本实施例中，远端设备广播的发现请求(即solicitation message)中没有携带第二指示信息，即发现请求中没有携带想要请求的中继设备的网络接入方式的指示。
步骤502、中继设备向远端设备发送发现响应，发现响应包括第一指示信息。
第一指示信息用于指示中继设备当前的网络接入方式，网络接入方式同上文实施例，具体可参见上文，此处不再赘述。
步骤503、远端设备根据发现响应确定是否通过中继设备建立网络连接。
本实施例提供的数据传输方法，中继设备在接收到远端设备广播的发现请求后，在向远端设备返回发现响应时，指示中继设备当前的网络接入方式，以使远端设备根据该指示决定能否选择该中继设备建立网络连接。通过上述方案可节省不必要的信令交互，实现远端设备快速接入网络。
图8为本申请实施例提供的一种数据传输方法的交互示意图。如图8所示，本实施例提供的方法包括如下步骤：
步骤601、远端设备向中继设备发送连接建立请求。
在本申请的一个实施例中，连接建立请求包括远端设备待传输数据的业务类型，即远端设备想要建立的业务类型。
可选的，在一些实施例中，连接建立请求还包括第二指示信息，第二指示信息用于指示远端设备允许的中继设备的网络接入方式。即连接建立请求中携带指示中继设备可以满足的网络接入方式。
步骤602、中继设备向远端设备发送连接建立响应。

在本申请的一个实施例中，连接建立响应包括第一指示信息，第一指示信息用于指示中继设备当前的网络接入方式。其中，第一指示信息指示的网络接入方式同上文实施例，具体可参见上文，此处不再赘述。
在本申请的一个实施例中，中继设备在接收到连接建立请求后，可根据连接建立请求确定其是否可以支持远端设备的业务类型。具体的，中继设备可根据自身的网络接入方式以及连接建立请求中的业务类型，确定其网络接入方式是否支持远端设备的业务类型：
在一种可能的实施方式中，如果中继设备确定其网络接入方式可支持远端设备的业务类型，中继设备向远端设备发送连接建立成功的响应消息。可选的，在该响应消息中指示中继设备当前的网络接入方式。
在另一种可能的实施方式中，如果中继设备确定其网络接入方式不支持远端设备的业务类型，中继设备可以向远端设备发送连接建立失败的响应消息。可选的，在该响应消息中指示中继设备当前的网络接入方式。
从上文可知，无论连接建立是否成功，中继设备均可以在连接建立响应中携带第一指示信息，用于向远端设备指示中继设备当前的网络接入方式。
步骤603、远端设备根据连接建立响应确定是否通过中继设备建立网络连接。
在本申请的一个实施例中，远端设备直接根据连接建立响应中的第三指示信息，确定是否通过中继设备建立网络连接。
在本申请的一个实施例中，远端设备可根据连接建立响应中的第一指示信息，确定是否通过中继设备建立网络连接。与上述实施例不同的是，本实施例的远端设备还需要通过自身判断，确定是否通过中继设备建立网络连接。
本实施例提供的数据传输方法，远端设备没有执行发现流程，直接在连接建立请求中携带自身想要建立的业务。中继设备在接收到连接建立请求后，判断是否可以支持该业务，并根据判断结果向远端设备返回连接建立响应，在连接建立响应中携带第一指示信息，用于指示中继设备当前的网络接入方式。通过上述方案，使得远端设备获知中继设备的网络接入方式，避免远端设备通过接入卫星网络的中继设备连接网络而导致数据延迟严重的问题，以及由于中继设备接入的网络不支持远端设备的业务而导致网络连接失败的问题。
