具体实施方式
为了便于理解，首先介绍本公开涉及的术语。
1、IAB-node
IAB的中继节点，支持通过NR进行无线接入和回传。通过NR Uu接口的终端功能子集(称为IAB-node中的IAB移动终端(Mobile Termination，MT)功能)连接上游IAB-node或IAB-donor分布式单元(Distributed Unit，DU)。IAB-node通过NR Uu接口的网络功能(称为IAB-node的IAB-DU功能)，提供到下游IAB-node和用户设备(user equipment，UE)的无线回传。也就是说一个IAB-done可以看做由一个IAB-MT及至少一个IAB-DU组成。
2、IAB-donor
网络侧NR回传的终止节点称为IAB-donor，是一个附加了IAB功能的网络设备。IAB-donor包括一个IAB-donor集中单元(central unit，CU)和一个或多个IAB-donor DU。
IAB-node和IAB-donor-CU之间的FI接口的控制面(F1C)业务通过IAB-donorDU和可选的中间跳IAB-node进行回传。IAB-node和IAB-donor-CU之间的F1接口的用户面(F1U)业务通过IAB-donorDU和可选的中间跳IAB-node进行回传。
3、IAB-node迁移
在支持IAB-node移动的场景中，比如车载移动IAB节点，随着IAB-node的移动改变，这样就需要执行IAB-node迁移(migration)过程，迁移过程包括两种，部分迁移(partialmigration)和完全迁移(fullmigration)。
部分迁移是指只有IAB-node上的IAB MT迁移(也可以称为切换)到一个新的IAB-donor，而IAB-node上的IAB DU还保持与原来的IAB-donor连接，即IAB DU上的UE上下文也保存在原来的IAB-donor上。 而完全迁移是指IAB-node上的IAB MT迁移(也可以称为切换)到一个新的IAB-donor，且IAB-node上的IAB DU也迁移(也可以称为切换)到一个新的IAB-donor。为了更好的理解本公开实施例公开的一种迁移的方法，下面首先对本公开实施例适用的通信系统进行描述。
请参见图1，图1为本公开实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个IAB-donor、一个IAB-node和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定，实际应用中可以包括两个或两个以上的IAB-donor，两个或两个以上的IAB-donor。图1所示的通信系统以包括1个IAB-donor 11、一个IAB-node 12为例和一个终端设备13。
需要说明的是，本公开实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。
本公开实施例中的IAB-donor是网络侧的一种附加了IAB功能的用于发射或接收信号的实体。例如，IAB-donor可以为附加了IAB功能的演进型基站(evolved NodeB，eNB)、附加了IAB功能的传输点(transmission reception point，TRP)、NR系统中的附加了IAB功能的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的附加了IAB功能的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开的实施例对IAB-donor所采用的具体技术和具体设备形态不做限定。本公开实施例提供的IAB-donor可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本公开实施例中的IAB-node是为下游IAB-node和用户设备(user equipment，UE)提供无线回传的中继节点。
本公开实施例中的终端设备是13用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本公开的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
本系统中，终端设备、IAB-donor及IAB-node可以实现本公开图2至图4任一实施例所示的方法，另外，终端设备还可以实现本公开图5、图8和图9所述的方法，IAB-donor可以实现本公开图6实施例所示的方法，IAB-node可以实现本公开图7实施例所示的方法。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
通常，在移动IAB-node移动过程中，如果IAB-node中的IAB-DU需要迁移到新的IAB-donor上，则IAB-DU下服务的所有连接态UE也需要一起迁移(即切换)到新的IAB-donor或基站上，因此，就需要IAB-donor、IAB-node可以准确确定on-board UE，进而将on-board UE切换到新的IAB-donor上。
下面结合各流程图，对本公开实施例提供的车载终端设备的识别方法进行详细的说明。
请参见图2，图2是本公开实施例提供的一种车载终端设备的识别方法的流程示意图。本实施例提供的方法，可以由终端设备执行，或者也可以由IAB-node执行，或者，还可以由IAB-donor执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤201，确定终端设备的第一辅助信息及接入和回传的中继节点IAB-node的第二辅助信息。
可选的，第一辅助信息，可以为终端设备的第一位置信息。其中，第一位置信息可以为任意可描述终端设备位置的信息。可选的，第一位置信息可以包括以下至少一项：终端设备的经纬度信息、终端设 备的移动速度、终端设备的移动方向、终端设备的位置信息的准确度等等。相应的，第二辅助信息，可以为IAB-node的第二位置信息。第二位置信息，可以包括以下至少一项：IAB-node的经纬度信息、IAB-node的轨迹信息、IAB-node的高度信息、IAB-node的速度信息及IAB-node位置信息的准确度等等。
或者，第一辅助信息还可以为终端设备的非接入(non access stratum，NAS)层信息。其中，终端设备的NAS信息可以包括应用层信息，可以为任意可反映终端设备中当前正在进行的业务的信息，比如，正在进行的业务的类型，或者正在进行的业务的名称等等。相应的，第二辅助信息，可以为IAB-node的车载状态指示信息。其中，车载状态指示信息，用于指示IAB-node是否允许终端设备登录。比如，车载状态指示信息可能为车载使能指示(onboard enable indication),或者也可能为车载去使能指示(onboard disable indication)。
举例来说，若IAB-node为公交车，由于其可能需要为终端设备提供上车、下车等刷卡服务，从而其对应的车载状态指示信息可能为onboard enable indication；或者，若IAB-node为私家车，由于其无需提供上、下车等刷卡服务，为了保证该IAB-node的私密性和安全性，则其对应的车载状态指示信息可能为onboard disable indication。
在本公开中，非接入层包括NAS信令、NAS用户平面，也包括应用层。非接入层是指在终端设备上除了接入层以外的其他协议层。
步骤202，根据第一辅助信息及第二辅助信息，确定终端设备是否为车载终端设备。
通常，由于IAB-node处于移动状态，若终端设备为车载终端设备，则其也应该处于移动状态。因此，本公开中，可以根据终端设备的第一位置信息及IAB-node的第二位置信息，来确定二者之间的移动状态是否相同，进而来确定终端设备是否为车载终端设备。
举例来说，若终端设备与IAB-node的移动状态同步，那么就可以确定终端设备为车载终端设备，反之则可以确定终端设备为非车载终端设备，或者为周边终端设备。
或者，由于处于移动状态的IAB-node通常为车载IAB-node,其提供的服务通常为特定类型的服务，比如近场通信(Near Field Communication，NFC)刷卡上车、下车服务等。因此，本公开中，也可以根据终端设备的NAS层信息及IAB-node的车载状态指示信息，来确定终端设备是否为车载终端设备。举例来说，若终端设备中正在进行的业务为车载类业务、且IAB-node的车载状态指示信息指示的为允许登录指示，那么可以确定终端设备为车载终端设备。否则可以确定终端设备为非车载终端设备。
可选的，在本公开中，当IAB-donor确定终端是否是车载终端设备后，IAB-donor可以向核心网节点发送所述终端设备是否是车载终端设备的信息，所述核心网节点可以是接入管理功能(Access Management Funciton，AMF)节点或位置管理功能(Location Management Function，LMF)节点。若所述核心网节点是LMF，IAB-donor可以将所述终端设备是否是车载终端设备的信息包括在新空口定位协议A(NR Postioning Protocal A，NRPPa)消息中，所述NRPPa消息可以是定位信息反馈消息或其他NRRPa消息，LMF节点可以考虑所述信息用于终端设备的定位；若所述核心网节点是AMF，IAB-donor可以将所述终端设备是否是车载终端设备的信息包括在NGAP消息中，AMF可以根据所述信息对终端设备进行移动性管理。
本公开中，首先确定终端设备的第一辅助信息及IAB-node的第二辅助信息，之后根据第一辅助信息及第二辅助信息，确定终端设备是否为车载终端设备。由此，实现了准确确定终端设备是否为车载终端设备，从而保证了车载终端设备可以优先接入IAB节点并随着IAB节点的移动进行可靠准确及高效的小区选择、小区重选或切换，提高了通信系统的性能。
请参见图3，图3是本公开实施例提供的另一种车载终端设备的识别方法的流程示意图。本实施例提供的方法，可以由终端设备执行，或者也可以由IAB-node执行，或者，还可以由IAB-donor执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤301，确定终端设备的第一位置信息及IAB-node的第二位置信息。
上述步骤301的具体实现过程，可以参照本公开任一实施例的详细描述，此处不再赘述。
步骤302，根据第一位置信息及第二位置信息，确定终端设备与IAB-node的相对位置。
本公开中，终端设备与IAB-node的相对位置，可以包括终端设备与IAB-node的相对经纬度、相对移动速度、相对移动方向等等。
可选的，第一位置信息及第二位置信息中，可能包括某个时段内终端设备及IAB-node分别对应的经纬度信息，由此，则可以根据同一时刻两个经纬度信息间的差距，确定二者的相对经纬度。或者，第 一位置信息及第二位置信息中，还可能包括终端设备及IAB-node的移动速度及移动方向，那么则可以确定终端设备相对于IAB-node的移动速度及移动方向。或者，第一位置信息及第二位置信息中，还可能包括终端设备及IAB-node的轨迹信息，那么则可以确定二者之间的相对轨迹，等等。
步骤303，根据相对位置，确定终端设备是否为车载终端设备。
可以理解的是，若终端设备与IAB-node的相对位置不变，比如二者的相对经纬度、相对速度及相对轨迹等不变，则可以认为终端设备为车载终端设备。
可选的，IAB-donor在确定了终端设备是否是车载终端设备后，还可以向核心网节点发送所述终端设备是否是车载终端设备的信息。其具体实现方式可参照本公开任一实施例的详细描述，此处不再赘述。
本公开中，首先确定终端设备的第一位置信息及IAB-node的第二位置信息，之后根据第一位置信息及第二位置信息，确定二者的相对位置，之后再根据相对位置，确定终端设备是否为车载终端设备。由此，使得终端设备、IAB-node及IAB-donor都可以准确确定终端设备是否为车载终端设备，从而保证了车载终端设备可以优先接入IAB节点并随着IAB节点的移动进行可靠准确及高效的小区选择、小区重选或切换，提高了通信系统的性能。
请参见图4，图4是本公开实施例提供的另一种车载终端设备的识别方法的流程示意图。本实施例提供的方法，可以由终端设备执行，或者也可以由IAB-node执行，或者，还可以由IAB-donor执行。如图4所示，该方法可以包括但不限于如下步骤：
步骤401，确定终端设备的第一位置信息及IAB-node的第二位置信息。
步骤402，根据第一位置信息及第二位置信息，确定终端设备与IAB-node的相对位置。
上述步骤401及步骤402的具体实现过程，可以参照本公开任一实施例的详细描述，此处不再赘述。
步骤403，确定用于识别终端设备是否为车载终端设备的评估信息。
其中，该评估信息，可以是由网络设备确定的，或者，也可以协议约定的，或者，还可以预先配置在终端设备、IAB-donor、或者IAB-node中的，本公开对此不做限定。
步骤404，根据相对位置信息与评估信息，确定终端设备是否为车载终端设备。
可选的，评估信息包括以下至少一项：位置区域范围信息；速度范围信息；评估的位置偏移信息；评估的时间信息；及评估的迟滞信息。
其中，位置区域范围信息及速度范围信息，可以用于指示该评估信息适用的场景。
可选的，位置区域范围信息，可以是跟踪区(tracking area，TA)列表、小区列表、地理位置对应的经纬度区域等。在一些实施例中，位置区域范围信息，还可以是随时间变化的列表信息，例如列表中的每一项包括一个时间段和其对应一个位置区域范围。速度范围信息可以是一个速度范围。在一些实施例中，速度范围信息，还可以是随时间变化的列表信息，例如列表中的每一项包括一个时间段和其对应一个速度范围。
也就是说，仅在IAB-node、或终端设备、或IAB-node及终端设备均落入位置区域范围信息指示的位置区域时、且其速度在速度范围信息指示的速度范围内时，才可以基于位置偏移信息、时间信息及迟滞信息等，对相对位置进行评估。
评估的位置偏移信息，用于指示评估相对位置时的偏移范围，比如经纬度的偏移范围、速度的偏移范围等等。举例来说，若终端设备的经纬度与IAB-node间的经纬度的差值在该偏移范围内，则可以认为二者的经纬度相对不变。
评估的时间信息，用于指示评估相对位置的时间。可选的，该评估的时间信息，可以为一个时间范围，那么就可以根据时间范围内二者的相对位置，来确定终端设备在该时间范围内是否为车载终端设备。或者，该评估时间信息，也可以为一个时间长度，那么就可以根据当前时刻及之后的(或之前的)该时间长度内二者的相对位置，来确定终端设备在该时间长度指示的时间内是否为车载终端设备。
评估的迟滞信息，用于指示评估相对位置的迟滞区间，以避免终端设备在两个状态(即onboard和offboard)之间频繁切换。比如在已经确定终端设备为车载UE后，如果终端设备的经纬度与IAB-node间的经纬度的差值超出了偏移范围加迟滞范围，则可判断UE已经退出(offboard)，即不是车载UE。而如果终端设备的经纬度与IAB-node间的经纬度的差值超出偏移范围，但没有超出偏移范围加迟滞范围，则可以判断UE仍然是车载UE。
本公开中，在确定了终端设备与IAB-node间的相对位置后，再根据评估信息，对相对位置进行评估，以确定终端设备是否为车载终端设备。
举例来说，若评估信息中包括评估的经纬度偏移范围、速度偏移范围及评估的时间范围，那么即可 以根据评估的时间范围内，二者的相对经纬度是否在偏移范围内、及二者的相对速度是否在偏移范围内，来确定终端设备是否为车载终端设备。
可选的，IAB-donor在确定了终端设备是否是车载终端设备后，还可以向核心网节点发送所述终端设备是否是车载终端设备的信息。其具体实现方式可参照本公开任一实施例的详细描述，此处不再赘述。
本公开中，首先确定终端设备的第一位置信息及IAB-node的第二位置信息，之后根据第一位置信息及第二位置信息，确定二者的相对位置，之后再确定评估信息，然后再根据相对位置及评估信息，确定终端设备是否为车载终端设备。由此，使得终端设备、IAB-node及IAB-donor都可以准确确定终端设备是否为车载终端设备，从而保证了车载终端设备可以优先接入IAB节点并随着IAB节点的移动进行可靠准确及高效的小区选择、小区重选或切换，提高了通信系统的性能。

步骤502，接收IAB donor发送的IAB-node的第二位置信息。
可选的，终端设备可以通过无线资源控制(radio resource control,RRC)消息接收IAB-donor发送的第二位置信息。其中，该RRC消息，可以为系统消息，或者也可以为RRC重配消息，或者，还可以为RRC是否消息等等，本公开对此不做限定。
需要说明的是，上述步骤501和步骤502，可以同时执行，或者也可以先执行步骤502，再执行步骤501，本公开对此不做限定。
步骤503，根据第一位置信息及第二位置信息，确定终端设备与IAB-node的相对位置。

本公开中，由于车载终端设备随着IAB-node的切换，也需要切换到新的IAB-donor上。而车载终端设备与周边终端设备切换到新的IAB-donor的过程或方式不同。因此，本公开中，终端设备在确定其是否为车载终端设备后，可以向IAB-donor发送第一指示信息，以向IAB-donor指示其是否为车载终端设备，进而再由IAB-donor即可向IAB-node发送第二指示信息，以指示该终端设备是否为车载终端设备。
可选的，IAB-donor可以通过F1AP消息向IAB-node发送第二指示信息，其中，F1AP消息可以是 UE上下文建立请求消息、UE上下文修改请求消息或其他F1AP消息，本公开对此不做限定。本公开中，终端设备在确定其是否为车载终端设备后，则可以在需要时，根据其是否为车载终端设备，执行对应的操作。
之后，IAB-node可将所述第二指示信息保存在UE上下文中。IAB-donor和IAB-node分别保存了终端设备是否为车载终端设备的指示信息后，当在执行车载UE的相关操作(例如群切换和/或RACH-less)时，IAB-donor或IAB-node将根据保存的on-board或off-board指示，对on-board UE执行相关操作。
在一些实施例中，若终端设备处于RRC空闲态(ILDE)或RRC非激活态(INACTIVE)，或通过RRC释放消息接收了IAB-donor发送的第二位置信息后进入RRC_ILDE或RRC_INACTIVE状态。那么终端设备即可在确定其为车载终端设备时，则执行车载UE的小区选择和小区重选过程。在另一些实施例中，若UE处于RRC连接(CONNECTED)态，或UE从RRC_ILDE或RRC_INACTIVE状态进入RRC_CONNECTED状态，那么UE在确定其是否为车载终端设备后，可以通过RRC消息向IAB-donor发送onboard指示或offboard指示。其中，RRC消息可以是RRC建立请求消息、RRC恢复请求消息、RRC建立完成消息、RRC恢复完成消息、测量报告和/或其他RRC消息。
可选的，IAB-donor在确定了终端设备是否是车载终端设备后，还可以向核心网节点发送所述终端设备是否是车载终端设备的信息。其具体实现方式可参照本公开任一实施例的详细描述，此处不再赘述。
本公开中，终端设备首先确定其自身的第一位置信息，之后在接收到IAB-donor发送的IAB-node的第二位置信息后，即可根据第一位置信息及第二位置信息，确定二者的相对位置，进而再根据相对位置，确定终端设备是否为IAB-node的车载终端设备，之后即可向IAB-donor发送第一指示信息，以指示其是否为车载终端设备的。由此，终端设备通过根据其与IAB-node间的相对位置，即可确定其是否为车载终端设备，进而将确定的结果指示给IAB-donor,从而使得终端设备、IAB-node及IAB-donor都可以准确确定终端设备是否为车载终端设备，从而保证了车载终端设备可以优先接入IAB节点并随着IAB节点的移动进行可靠准确及高效的小区选择、小区重选或切换，提高了通信系统的性能。
