当前，随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性和复杂性，第三代合作伙伴计划(3rd generation partnership project，3GPP)国际标准组织开始研发5G。5G的主要应用场景为：增强移动超宽带(enhance mobile broadband，eMBB)、超可靠低时延通信(ultra reliable low latency communications，URLLC)以及大规模机器类通信(massive machine type communication，mMTC)。eMBB以用户获得多媒体内容、服务和数据为目标。eMBB的需求增长十分迅速。另一方面，由于eMBB可能部署在不同的场景中，比如室内，市区，农村等，其能力和需求的差别也比较大，所以不能一概而论，必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。
此外，目前3GPP正在研究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。相比地面蜂窝网通信，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，一般的地面通信网络不能覆盖海洋、高山、沙漠等无法搭设接入网设备的区域。或者，地面通信网络不覆盖某些人口稀少的区域。而对于卫星通信来说，由于一颗卫星可以覆盖较大的地面区域，且卫星可以围绕地球做轨道运动，因此，理论上讲，地球上每一个角落都可以被卫星通信网络所覆盖。
其次，卫星通信有较大的社会价值。卫星通信可以以较低的成本覆盖到边远山区、贫穷落后的国家或地区，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。从这个角度看来，卫星通信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，卫星通信距离远的优势，且通信距离的增大并没有明显增加通信的成本。
最后，卫星通信的稳定性高，不受自然灾害的影响。
通信卫星按照轨道高度的不同分为低地球轨道(low earth orbit，LEO)卫星、中地球轨道(medium earth orbit，MEO)卫星、地球同步轨道(geostationary earth orbit，GEO)卫星、高椭圆轨道(high elliptical orbit，HEO)卫星等。目前阶段主要研究的是LEO卫星和GEO卫星。
LEO卫星高度范围一般在500km～1500km。相应地，LEO卫星的轨道周期约为1.5小时～2小时。对于LEO卫星而言，用户间单跳通信的信号传播延迟一般小于20ms。LEO卫星的最大卫星可视时间约为20分钟。LEO卫星具有信号传播距离短，链路损耗少，对用 户的终端设备的发射功率要求不高等优点。
GEO卫星的轨道高度为35786km。GEO卫星围绕地球旋转的周期为24小时。对于GEO卫星而言，用户间单跳通信的信号传播延迟一般约为250ms。
为了保证卫星的覆盖以及提升整个卫星通信***的***容量，卫星通常采用多波束覆盖地面区域。因此，一颗卫星可以形成几十甚至数百个波束来覆盖地面区域。卫星的一个波束大约可以覆盖直径几十至上百公里的地面区域。目前，NTN***包括NR-NTN***和物联网(internet of things，IoT)-NTN***。
无论是在前文提到的5G的主要应用场景(如eMBB)，还是NTN场景，接入网设备均会收到针对终端设备的寻呼消息。相关技术中，在收到针对终端设备的寻呼消息之后，接入网设备会直接发送该寻呼消息，以在该接入网设备对应的小区内实现该终端设备的寻呼。但是，接入网设备发送的某个或某些寻呼消息可能是无用的或没有必要的。
例如，某些终端设备可能仅支持半双工(half duplex)模式。对于仅支持半双工模式的终端设备而言，该终端设备不能同时进行收发操作。但是，接入网设备可能并未实现半双工模式。因此，该接入网设备并不允许或不支持半双工模式的终端设备接入。在这种情况下，对于仅支持半双工模式的终端设备而言，接入网设备发送此类终端设备的寻呼消息是没有必要的，因为仅支持半双工模式的终端设备不可能驻留在该接入网设备的小区。
又如，如果终端设备希望接入NTN，则该终端设备可能需要具备某个或某些必要(essential)能力(简称NTN必要能力)，如卫星定位能力。如果某个终端设备不具备NTN接入能力，而接入网设备对应的小区为NTN小区，则接入网设备在该NTN小区直接发送针对该终端设备的寻呼消息是没有必要的，因为该终端设备是无法接入该NTN小区的。
综上可知，在一些情况下，某个或某些寻呼消息的发送是没有必要或无用的。如果接入网设备直接发送该寻呼消息，会浪费寻呼资源。此外，此类寻呼消息的发送也可能会增加其他终端设备的寻呼虚警(false alarm)，从而增加其他终端设备的功耗。例如，其他终端设备可能与该终端设备共享寻呼时机(paging occasion，PO)，而其他终端设备需要对物理下行共享信道(physical downlink shared channel，PDSCH)解码之后，才能确定该寻呼消息是否是发送给自己的寻呼消息，这种解码过程实际上是没有必要的，只会浪费其他终端设备的功耗。
针对上述问题，本申请实施例向接入网设备发送第一信息。该第一信息可用于指示终端设备的终端设备能力。该第一信息的引入有助于接入网设备对寻呼消息的发送进行控制，尽量避免传输不必要的寻呼消息。
下面结合图2，对本申请实施例进行详细地举例说明。参见图2，图2所述的方法由第一设备、第一接入网设备以及第一终端设备执行。
在一些实施例中，该第一终端设备可以是具有或不具有半双工能力的终端设备。或者说，该第一终端设备可以是支持或不支持半双工模式的终端设备。或者说，该第一终端设备可以是采用或不采用半双工模式工作的终端设备。本申请实施例提到的半双工例如可以指半双工-频分双工(half duplex frequency division duplexing，HD-FDD)。
在一些实施例中，该第一终端设备可以是降低能力的终端设备(或称RedCap终端)。该降低能力的终端设备例如可以是某些协议(如3GPP的R17)所定义的降低能力的终端设备。
例如，第一终端设备可以是应用于工业场景的终端设备。作为一个具体的示例，第一终端设备可以是工业无线传感器(industrial wireless sensors)。与URLLC场景中的终端设备相比，工业无线传感器对时延和可靠性具有相对较低的要求。同时，工业无线传感器的成本和功耗通常也低于URLLC和eMBB场景中的终端设备的成本和功耗。
又如，第一终端设备可以是应用于视频监控场景(如智慧城市或工业工厂中的视频监控场景)的终端设备。作为一个具体的示例，第一终端设备可以是应用在智慧城市中的视频监控设备。该视频监控设备可以进行数据收集和处理，以便于更有效的进行城市资源的 监测和控制，给城市居民提供更有效的服务。
又如，第一终端设备可以是小尺寸的可穿戴设备。作为一个具体的示例，该第一终端设备可以是智能手表、手环、戒指等。或者，该可穿戴设备可以是电子健康设备以及一些医疗监测设备等。
为了降低空口信令、快速恢复无线连接和快速恢复数据业务，某些通信***(如NR***)定义了三种RRC状态：RRC空闲态(RRC-IDLE)，RRC连接态(RRC_CONNECTED)，以及RRC去激活态(RRC_INACTIVE)。本申请实施例提及的第一终端设备可以是处于RRC空闲态(RRC-IDLE)的终端设备，也可以是处于RRC连接态(RRC_CONNECTED)的终端设备，也可以是处于RRC去激活态(RRC_INACTIVE)的终端设备。
例如，第一终端设备可以是RRC空闲态下的终端设备。在RRC空闲态下，移动性为基于第一终端设备的小区重选，寻呼(paging)过程由CN发起，且寻呼区域由CN配置。接入网设备不存在第一终端设备上下文，也不存在第一终端设备对应的RRC连接。
又如，第一终端设备可以是RRC连接态下的终端设备。在RRC连接态下，第一终端设备存在RRC连接，且接入网设备和第一终端设备存在第一终端设备对应的接入层(access stratum，AS)上下文。此外，在RRC连接态下，接入网设备能够知道第一终端设备的位置是小区级别的位置，第一终端设备的移动性由接入网设备控制，且第一终端设备和接入网设备之间可以传输单播数据。
又如，第一终端设备可以是RRC去激活态下的终端设备。在RRC去激活态下，第一终端设备的移动性为基于终端设备的小区重选，且存在CN-NR之间的连接。第一终端设备的AS上下文存在于某个接入网设备上。第一终端设备对于RAN是可达的，且第一终端设备的相关参数可以由RAN配置。当第一终端设备在RAN配置的RAN通知区域(RAN notification area，RNA)内移动时，该第一终端设备不需要通知接入网设备。当第一终端设备移动出该RAN通知区域时，需要通知接入网设备。在RRC去激活态下，第一终端设备的寻呼过程由RAN触发，且基于RAN的寻呼区域由RAN管理。此外，接入网设备能够知道第一终端设备的位置是基于RAN的寻呼区域级别的。
在一些情况下，第一终端设备会从RRC去激活态转换为(或自主回到)RRC空闲态。例如，如果第一终端设备接收到CN触发的寻呼消息，则该第一终端设备会从RRC去激活态转换为RRC空闲态。又如，在第一终端设备发起RRC恢复请求、并启动定时器T319的情况下，如果该定时器T319超时，则该第一终端设备会从RRC去激活态转换为RRC空闲态。又如，如果第一终端设备对消息4(msg4)的完整性保护验证失败，则该第一终端设备会从RRC去激活态转换为RRC空闲态。又如，在第一终端设备执行小区重选的过程中，如果该第一终端设备选择到其他无线接入技术(radio access technology，RAT)对应的小区，则该第一终端设备会从RRC去激活态转换为RRC空闲态。又如，如果第一终端设备进入camp on any cell状态，则该第一终端设备会从RRC去激活态转换为RRC空闲态。
在一些实施例中，第一终端设备可以是能够接入TN的终端设备，简称TN终端设备；或者，第一终端设备也可以是能够接入NTN的终端设备，简称NTN终端设备；或者，第一终端设备可以既属于TN终端设备，也属于NTN终端设备。
图2中的第一设备可以是核心网(core network，CN)设备，如AMF。在另一些实施例中，该第一设备可以是接入网设备，如第一终端设备的锚点接入网设备。所谓锚点接入网设备，可以是控制第一终端设备进入非激活状态的接入网设备。或者说，锚点接入网设备可以是第一终端设备在连接状态下且进入非激活状态前为第一终端设备提供服务的最后一个接入网设备。
图2中的第一接入网设备指的是能够接收到针对第一终端设备的寻呼消息的接入网设备。在一些实施例中，该第一接入网设备可以是第一终端设备的注册区域内的任意一个接入网设备。在一些实施例中，该第一接入网设备可以是第一终端设备的RAN通知区域 内的任意一个接入网设备。
参见图2，在步骤S210，第一接入网设备接收第一信息。
在一些实施例中，该第一信息可以由前文提到的第一设备发送。
在一些实施例中，该第一信息可以是与第一接入网设备接收到的寻呼消息关联的信息。例如，第一信息可以承载于第一接入网设备接收到的寻呼消息。又如，第一信息也可以不属于寻呼消息的一部分，而是伴随寻呼消息同时传输至第一接入网设备的信息。
上述寻呼消息可以指节点间的寻呼消息。所谓节点间的寻呼消息，可以指接入网内的节点间寻呼消息，如接入网设备之间传输的寻呼消息。或者，节点间寻呼消息可以指接入网与核心网的节点间寻呼消息，如核心网设备向接入网设备发送的寻呼消息。
在一些实施例中，上述寻呼消息(即第一接入网设备接收到的寻呼消息)可以为CN触发的寻呼消息。所谓CN触发的寻呼消息可以指由核心网设备发起，并经接入网设备转发的寻呼消息。该核心网设备例如可以指AMF。进一步地，在一些实施例中，该寻呼消息可以是通过S1接口发送的消息。作为一个例子，该寻呼消息可以为S1AP消息中的寻呼消息或者节点间的用户设备无线寻呼信息(UERadioPagingInformation)消息。在具体实现时，可以扩展S1AP消息中的寻呼消息或者节点间的UERadioPagingInformation消息，以在该寻呼消息或者节点间的UERadioPagingInformation消息中增加上述第一信息对应的信元。
在一些实施例中，上述寻呼消息(即第一接入网设备接收到的寻呼消息)可以为RAN触发的寻呼消息。所谓RAN触发的寻呼消息可以指由接入网设备发起，并经其他接入网设备(如第一接入网设备)转发的寻呼消息。RAN触发的寻呼消息也可称为RAN寻呼消息。发起寻呼消息的接入网设备例如可以是前文提到的锚点接入网设备。进一步地，在一些实施例中，该寻呼消息可以是通过Xn接口发送的消息。作为一个例子，该寻呼消息可以为XnAP消息中的寻呼消息或者节点间的UERadioPagingInformation消息。在具体实现时，可以扩展XnAP消息中的寻呼消息或者节点间的UERadioPagingInformation消息，以在该寻呼消息或者节点间的UERadioPagingInformation消息中增加上述第一信息对应的信元。
在一些实施例中，步骤S210中的第一信息可用于确定是否传输(即传输或不传输)针对第一终端设备的寻呼消息。
在一些实施例中，该第一信息可用于指示(或确定)第一终端设备的终端设备能力。因此，在一些实施例中，可以将该第一信息称为第一终端设备的能力指示信息。
第一信息对第一终端设备能力的指示可以通过以下方式中的一种或多种方式实现：第一信息指示第一终端设备具有的终端设备能力，和/或，第一信息指示第一终端设备不具有的终端设备能力。
作为一个示例，第一信息可用于指示(或确定)以下信息中的一种或多种：第一终端设备具有半双工能力，第一终端设备不具有半双工能力，以及第一终端设备仅具有半双工能力。所谓“具有半双工能力”可以理解为支持半双工模式(如仅支持半双工模式)，或使用半双工模式工作。该示例中，第一信息指示的是第一终端设备是否具有半双工能力，因此，该第一信息有时也可称为半双工能力指示。
作为另一示例，第一信息可用于指示(或确定)以下信息中的一种或多种：第一终端设备具有接入NTN的能力，第一终端设备不具有接入NTN的能力，第一终端设备仅具有接入非NTN的能力，第一终端设备为TN终端设备，以及第一终端设备为NTN终端设备。所谓“不具有接入NTN的能力”可以理解为无法接入NTN，或者无法接入NTN小区。该示例中，第一信息指示的是第一终端设备是否具有NTN接入能力，因此，该第一信息有时也可称为NTN能力指示或非NTN能力指示。
作为又一示例，第一信息可以为上述两种信息的组合。例如，第一信息可用于指示第一终端设备具有或不具有半双工能力，并用于指示第一终端设备具有或不具有接入NTN 的能力。
第一信息可以直接指示第一终端设备具有或不具有某种终端设备能力，也可以间接指示第一终端设备具有或不具有某种终端设备能力。以第一信息指示第一终端设备不具有接入NTN的能力为例，第一信息可以直接指示第一终端设备是否具有接入NTN的能力，或者，第一信息也可以指示第一终端设备不具有接入NTN所需的某个或某些能力，从而间接指示第一终端设备不具有接入NTN的能力。
在一些实施例中，第一信息指示第一终端设备是否具有接入NTN的能力可以替换为：第一信息指示第一终端设备具有或不具有以下能力中的一种或多种：定位能力；时间提前量(timing advance，TA)预补偿能力；基于终端设备与接入网设备之间的往返时间(round trip time，RTT)对随机接入过程调整的能力；基于终端设备与接入网设备之间的RTT对非连续接收混合自动重传请求往返时间定时器(discontinuous reception hybrid automatic repeat request round trip time timer，DRX HARQ RTT timer)进行调整的能力；以及支持多个跟踪区域码(tracking area code，TAC)的能力。
例如，第一信息可以指示第一终端设备具有或不具有定位能力。该定位能力例如可以指基于卫星定位***进行定位的能力。该基于卫星定位***进行定位的能力例如可以指基于全球导航卫星***(global navigation satellite system，GNSS)进行定位的能力。
又如，第一信息可以指示第一终端设备具有或不具有TA预补偿能力。TA预补偿能力是指终端设备可以对随机接入请求进行TA预补偿。也就是说，终端设备可以根据一定的TA值，提前发送随机接入请求，从而调整随机接入请求到达接入网设备的时间。
又如，第一信息可以指示第一终端设备具有或不具有基于终端设备与接入网设备之间的RTT对相关过程或参数进行调整的能力(为了接入NTN，经常需要基于RTT对一些过程(如随机接入过程)或参数进行调整)。作为一个具体的例子，第一信息可以指示第一终端设备具有或不具有基于RTT(终端设备到接入网设备的RTT)对随机接入过程调整的能力(该能力也可称为随机接入信道(random access channel，RACH)适配能力)。对随机接入过程调整的能力例如可以包括实现如下功能的能力：终端设备在发送完前导码(preamble)之后，可以间隔RTT后再启动随机接入响应(random access response，RAR)时间窗(window)，以补偿NTN网络的传输延时。作为另一个具体的例子，第一信息可以指示第一终端设备具有或不具有基于RTT(终端设备到接入网设备的RTT)对DRX HARQ RTT timer进行调整的能力。在一些实施例中，该DRX HARQ RTT timer可以由RRC信令配置。对DRX HARQ RTT timer进行调整的能力也可称为DRX HARQ RTT timer扩展能力。基于该RTT对DRX HARQ RTT timer进行调整的能力例如可以包括：在DRX HARQ RTT timer的定时值的基础上附加一个RTT值，以补偿NTN网络的传输延时。
又如，第一信息可以指示第一终端设备具有或不具有支持多个TAC的能力(在NTN中，当终端设备移动至多个跟踪区域(tracking area，TA)的重叠区域时，通常需要同时支持多个TAC，即同时支持该多个TA分别对应的TAC)。对多个TAC的支持能力有时也可称为对软TAC(soft TAC)的支持能力。
本申请实施例向第一接入网设备发送第一信息，该第一信息可用于指示第一终端设备的终端设备能力，该第一信息的引入有助于接入网设备判断是否需要发送针对该第一终端设备的寻呼消息，从而可能节省寻呼资源以及降低其他终端设备检测寻呼消息的功耗。
继续参见图2，在一些实施例中，图2的方法还可以包括步骤S220，即第一接入网设备根据第一信息确定是否传输(传输或不传输)针对第一终端设备的寻呼消息(或空口(Uu)寻呼消息)。如果第一接入网设备确定传输针对第一终端设备的寻呼消息，则可以继续执行步骤S230，向第一终端设备传输针对第一终端设备的寻呼消息。
第一接入网设备传输针对第一终端设备的寻呼消息可以指：第一接入网设备传输的寻呼消息中包含该第一终端设备的寻呼标识(寻呼ID)。类似地，第一接入网设备不传输针对第一终端设备的寻呼消息可以指：第一接入网设备传输的寻呼消息中不包含该第一终端 设备的寻呼标识(寻呼ID)。
步骤S220的实现方式可以有多种。例如，第一接入网设备可以根据第一信息和第一接入网设备支持的设备能力，确定是否传输针对第一终端设备的寻呼消息。第一接入网设备支持的设备能力与终端设备能力对应。也就是说，第一接入网设备支持的设备能力是与终端设备能力关联的设备能力。例如，第一接入网设备支持的设备能力与终端设备能力为相同类型的能力。
在一些实施例中，当第一信息指示的终端设备能力为第一终端设备能力时，如果第一信息指示第一终端设备具有第一终端设备能力，且第一接入网设备支持第一终端设备能力，则第一接入网设备传输针对第一终端设备的寻呼消息；如果第一信息指示第一终端设备具有第一终端设备能力，且第一接入网设备不支持第一终端设备能力，则第一接入网设备不传输针对第一终端设备的寻呼消息。
例如，如果第一信息指示第一终端设备具有半双工能力，且第一接入网设备支持半双工能力，则第一接入网设备传输针对第一终端设备的寻呼消息。
又如，如果第一信息指示第一终端设备具有半双工能力，且第一接入网设备不支持半双工能力，则第一接入网设备不传输针对第一终端设备的寻呼消息。
例如，如果第一信息指示第一终端设备具有接入NTN的能力，且第一接入网设备具有支持接入NTN的能力的终端设备，则第一接入网设备传输针对第一终端设备的寻呼消息。
又如，如果第一信息指示第一终端设备具有接入NTN的能力，且第一接入网设备不支持具有支持接入NTN的能力的终端设备，则第一接入网设备不传输针对第一终端设备的寻呼消息。
在一些实施例中，当第一信息指示的终端设备能力为第二终端设备能力时，如果第一信息指示第一终端设备不具有第二终端设备能力，且第一接入网设备支持第一终端设备能力，则第一接入网设备传输针对第一终端设备的寻呼消息；如果第一信息指示第一终端设备不具有第二终端设备能力，且第一接入网设备不支持第一终端设备能力，则第一接入网设备不传输针对第一终端设备的寻呼消息。
在一些实施例中，上文提到的第一终端设备能力与第二终端设备能力属于不同类型的终端设备能力。例如，第一终端设备能力为接入TN的能力；第二终端设备能力为接入NTN的能力。也就是说，如果第一信息指示第一终端设备不具有接入NTN的能力，且第一接入网设备支持具有接入TN能力的终端设备，则第一接入网设备传输针对第一终端设备的寻呼消息；如果第一信息指示第一终端设备不具有接入NTN的能力，且第一接入网设备不支持具有接入TN能力的终端设备，则第一接入网设备不传输针对第一终端设备的寻呼消息。
需要说明的是，第一接入网设备可以对应一个或多个小区(即第一接入网设备覆盖范围内可能包含一个或多个小区)，第一接入网设备可以针对各个小区均执行步骤S220的判断逻辑。例如，步骤S220可以包括：第一接入网设备可以根据第一信息和第一接入网设备对应的第一小区(可以是第一接入网设备对应的任意一个小区)支持的设备能力，确定是否在该第一小区传输针对第一终端设备的寻呼消息。应当理解的是，如果第一接入网设备对应多个小区，则该多个小区支持的设备能力可以相同，也可以不同。
下面结合图3和图4，以第一信息承载于节点间寻呼消息，且该节点间寻呼消息为RAN触发的寻呼消息为例，对本申请实施例进行更为详细地举例说明。应注意，图3至图4的例子仅仅是为了帮助本领域技术人员理解本申请实施例，而非要将本申请实施例限于所例示的具体数值或具体场景。本领域技术人员根据所给出的图3至图4的例子，显然可以进行各种等价的修改或变化，这样的修改或变化也落入本申请实施例的范围内。
图3示出了终端设备1、锚点接入网设备、接入网设备1和接入网设备2。该锚点接入网设备可以是节点间寻呼消息的发起者。前文提到的第一终端设备可以对应于图3中的 终端设备1。前文提到的第一接入网设备可以对应于图3中的接入网设备1和接入网设备2中的任一个。前文提到的第一信息对应于图3中指示的终端设备1具有或不具有半双能力的信息。
在步骤S310，锚点接入网设备向接入网设备1和接入网设备2发送节点间寻呼消息。该节点间寻呼消息携带指示终端设备1具有或不具有半双工能力的信息(对应于前文提到的第一信息)。接收到该节点间寻呼消息之后，接入网设备1执行步骤S320，即根据终端设备1的半双工能力，以及接入网设备1自己对半双工能力的终端设备的支持情况，决定是否发送针对该第一终端设备的空口寻呼消息。例如，如果终端设备1仅支持半双工能力，而当前小区支持具有半双工能力的终端设备接入，则接入网设备1在当前小区传输针对终端设备1的空口寻呼消息。又如，如果终端设备1仅支持半双工能力，而当前小区不支持具有半双工能力的终端设备接入，则接入网设备1在当前小区不传输针对终端设备1的空口寻呼消息。接入网设备2可以采用与接入网设备1相同或类似的判断逻辑来决定是否发送针对终端设备1的空口寻呼消息，此处不再赘述。
图4示出了终端设备1、锚点接入网设备、接入网设备1和接入网设备2。该锚点接入网设备可以是节点间寻呼消息的发起者。前文提到的第一终端设备可以对应于图4中的终端设备1。前文提到的第一接入网设备可以对应于图4中的接入网设备1和接入网设备2中的任一个。前文提到的第一信息对应于图3中的指示终端设备1具有或不具有接入NTN的能力的信息。
在步骤S410，锚点接入网设备向接入网设备1和接入网设备2发送节点间寻呼消息。该节点间寻呼消息携带指示终端设备1具有或不具有接入NTN的能力的信息(对应于前文提到的第一信息)。接收到该节点间寻呼消息之后，接入网设备1执行步骤S420，即根据终端设备1是否具有接入NTN的能力，以及接入网设备1自己对此类终端设备的支持情况，决定是否向终端设备1发送针对该第一终端设备的空口寻呼消息。例如，如果终端设备1仅能够接入非NTN，而当前小区能够支持此类终端设备的接入，则接入网设备1在当前小区传输针对终端设备1的空口寻呼消息。又如，如果终端设备1仅能够接入非NTN，而当前小区不支持此类终端设备的接入，则接入网设备1在当前小区不传输针对终端设备1的空口寻呼消息。接入网设备2可以采用与接入网设备1相同或类似的判断逻辑来决定是否发送针对终端设备1的空口寻呼消息，此处不再赘述。
