具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
为了便于理解，首先介绍本公开涉及的术语。
1、非地面网络(non-terrestrial networks，NTN)
非地面网络是由卫星通信系统与5G相融合，取长补短，共同构成全球无缝覆盖的海陆空天地一体化综合通信网，满足用户无处不在的多种业务需求，是未来通信发展的重要方向。
2、定时提前量(timing advance，TA)
信号在空间传输是有延迟的，如终端设备在呼叫期间向远离基站的方向移动，则从基站发出的信号 将“越来越迟”的到达终端设备，与此同时，终端设备的信号也会“越来越迟”的到达基站，延迟过长会导致基站收到的某终端设备在本时隙上的信号与基站收下一个其它终端设备信号的时隙相互重叠，引起码间干扰。因此，在数据传输过程中，终端设备的上行传输需要有一定的提前量，以保证不同的用户的上行传输到达基站的时间间隔小于预定义的门限。基站可以在下行信道上向终端设备发送定时提前命令，指示终端设备提前发送的时间，这个时间就是定时提前量。
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网络设备和一个终端设备，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网络设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备11、一个终端设备12和一个卫星13为例。
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。
本公开实施例中的网络设备11是网络侧的一种用于发射或接收信号的实体。例如，网络设备11可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开的实施例对网络设备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网络设备可以是由集中单元(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。
本公开实施例中的终端设备12是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设备(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。
通常，在终端设备对应的定时提前量(timing advance，TA)补偿值T TA的变化量，或者终端设备的服务链路TA的变化量超过一定门限值时，触发位置信息上报。当终端设备移动，或者卫星移动时，都可能造成TA变化而触发位置信息上报。这跟引入基于终端设备的位置信息的TA上报的初衷是违背的。我们之所以引入位置信息上报，就是因为通过终端设备的位置信息，网络可以计算终端设备的和卫星间的往返时延(round-trip time，RTT)，从而可以基于此往返时延，进行上行调度，不需要终端设备频繁上报TA。因此需要对触发条件进行一定的修改，把卫星移动的因素剔除出去。下面结合附图对本公开所提供的一种位置信息的上报方法及其装置进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种位置信息的上报方法的流程示意图，该方法由终端设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤201，确定终端设备对应的定时提前TA变化值大于门限值，其中，TA变化由终端设备的位置变化引起。
本公开中，考虑到在NTN网络中，由于卫星的覆盖范围较大，网络设备需要知道终端设备的位置信息才能为终端设备选择合适的接入和移动管理功能(authentication management function，AMF)，从而需要终端设备在满足触发条件或者周期性的上报其位置信息。而由于终端设备的移动或者卫星的移动，都可能使得终端设备满足上报位置信息的触发条件，从而导致资源浪费，为了避免终端设备没有移动，仅因卫星在移动，造成TA变化值大于门限值，而触发位置信息上报的现象，本公开可以剔除因卫星移动对TA变化值的影响，仅保留因终端设备的位置变化引起的TA变化值，并在终端设备对应的由自身位置变化引起的定时提前TA变化值大于门限值的情况下，向网络设备上报终端设备的位置信息。
本公开中，终端设备在获取位置信息后，可以根据当前位置信息，或者前一次上报的位置信息，及当前卫星位置信息，或者前一次上报位置信息时对应的卫星位置，确定TA变化值，之后，可以将TA 变化值与预设的门限值进行比较。
步骤202，向网络设备上报终端设备的位置信息。
本公开中，在终端设备对应的定时提前TA变化值大于门限值的情况下，可以确定终端设备位置发生了改变、并满足了位置信息的上报条件，此时，终端设备则可以向网络设备上报终端设备的位置信息。由此，网络设备即可根据终端设备上报的位置信息，计算终端设备的和卫星间的RTT。
可选的，在确定当前的TA变化值小于或等于门限值的情况下，不触发向网络设备上报位置信息。
可选的，终端设备可以仅在有可用位置信息的时，进行位置信息的上报，其中位置信息可以为commonLocationInfo、bt-LocationInfo、wlan-LocationInfo、sensor-LocationInfo等。
可选的，当网络设备通过连接重配消息指示上报位置信息的配置信息时，终端设备可以在配置信息的reportconfig IE对应的测试报告中，配置位置信息。由此，网络设备即可根据测试报告，确定终端设备的位置信息。
本公开中，终端设备在确定终端设备对应的由终端设备的位置变化引起的定时提前TA变化值大于门限值后，向网络设备上报终端设备的位置信息。由此，终端设备仅在自身的位置变化引起的TA变化值大于门限值的情况下，才进行位置信息上报，从而避免因卫星移动触发位置信息上报的现象，有效地避免资源的浪费。
请参见图3，图3是本公开实施例提供的一种位置信息的上报方法的流程示意图，该方法由终端设备执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤301，根据终端设备当前对应的第一位置信息及卫星当前对应的第二位置信息，确定第一TA值。
其中，第一TA值是根据终端设备位置与卫星位置确定的，所以第一TA值为服务链路service link对应的TA值，也就是终端设备特有specific定时提前TA值。
本公开中，终端设备可以根据卫星对应的星历，确定卫星当前对应的第二位置信息，或者，也可以根据其他终端设备或者网络设备的指示，确定第二位置信息，本公开对此不做限定。
步骤302，根据终端设备前一次上报的第三位置信息及第二位置信息，确定第二TA值。
本公开中，终端设备可以在上报位置信息时，记录下对应的终端设备的位置信息及卫星的位置信息，进而即可在当前时刻根据记录的前一次上报的终端设备的第三位置信息及当前卫星的第二位置信息，计算出第二TA值。
步骤303，根据第一TA值与第二TA值间的差值，确定TA变化值。
本公开中，可以将第一TA值与第二TA值进行做差，之后，可以将此差值确定为终端设备对应的TA变化值。
步骤304，确定终端设备对应的定时提前TA变化值大于门限值。
步骤305，向网络设备上报终端设备的位置信息。
本公开中，步骤304-步骤305的具体实现过程，可参见本公开任一实施例的详细描述，在此不再赘述。
可以理解的是，由于服务链路对应的TA值可以表征终端设备与卫星间的距离，本公开中基于当前卫星的第二位置信息，分别与终端设备移动前后的位置信息，确定两次服务链路对应的TA值，进而再确定TA变化值，由于该TA变化值，是基于卫星的同一位置信息确定的，即未考虑卫星位置的变化，从而使得判断是否满足位置信息上报条件时，仅考虑了终端设备位置变化，而未考虑卫星的位置变化，有效避免了终端设备位置未变化，仅卫星位置变化触发的位置信息上报，而造成的资源浪费。
本公开中，终端设备可以根据终端设备当前对应的第一位置信息及卫星当前对应的第二位置信息，确定第一TA值，并根据终端设备前一次上报的第三位置信息及第二位置信息，确定第二TA值，之后，可以根据第一TA值与第二TA值间的差值，确定TA变化值，在终端设备对应的定时提前TA变化值大于门限值的情况下，可以向网络设备上报终端设备的位置信息。由此，通过基于卫星当前的位置信息，及终端设备移动前后的位置信息，确定TA变化值，有效剔除了因卫星移动导致的TA变化值部分，从而避免仅因卫星移动触发位置信息上报的现象，有效地避免资源的浪费。
请参见图4，图4是本公开实施例提供的一种位置信息的上报方法的流程示意图，该方法由终端设备执行。如图4所示，该方法可以包括但不限于如下步骤：
步骤401，根据终端设备当前对应的第一位置信息及卫星当前对应的第二位置信息，确定第一TA补偿值。
本公开中，在随机接入过程中，当终端在一个随机接入信道(random access channel，RACH)时机发送前导码preamble后，网络在接收到该preamble时需要知道对应的发送时机，以便在随机接入响应时正确寻址该随机接入请求，以及进行上行定时调整。但是在卫星通信系统中，不同终端到达基站的往 返时延差值最高可达10.3ms，当时机之间的间隔小于最大往返时延差值时，不同时机的preamble接收窗口存在重叠，基站无法从接收到的preamble推测出其发送的时机子帧以及上行定时偏差。对上述preamble接收模糊性问题，可以通过TA预补偿来解决，也即终端设备在发送preamble前，将终端设备的上行链路(up-link，UL)定时timing，根据终端和基站之间的RTT来进行提前，从而保证不同终端设备采用相同时机发送的preamble到达基站的时间差均限制在1个子帧以内。
本公开中，终端设备可以根据卫星对应的星历，确定卫星当前对应的第二位置信息，或者，也可以根据其他终端设备或者网络设备的指示，确定第二位置信息，本公开对此不做限定。
本公开中，终端设备在获取当前位置信息的同时，可以确定当前服务卫星的位置信息，并将终端设备当前的位置信息确定为第一位置信息，将卫星当前的位置信息确定为第二位置信息，之后，可以根据终端设备当前对应的第一位置信息及卫星当前对应的第二位置信息，计算出第一TA补偿值T TA。
通常，T TA可以等同于终端设备和卫星间的RTT再加上公共common TA，其中，common TA，为卫星到网络设备间的链路的RTT。
步骤402，根据终端设备前一次上报的第三位置信息及第二位置信息，确定第二TA补偿值。
本公开中，终端设备可以在上报位置信息时，记录下对应的终端设备的位置信息及卫星的位置信息，进而即可在当前时刻根据记录的前一次上报的终端设备的第三位置信息及当前卫星的第二位置，计算出第二TA补偿值。
步骤403，根据第一TA补偿值与第二TA补偿值间的差值，确定TA变化值。
本公开中，可以将第一TA补偿值与第二TA补偿值进行做差，之后，可以将此差值确定为终端设备对应的TA变化值。
步骤404，确定终端设备对应的定时提前TA变化值大于门限值。
步骤405，向网络设备上报终端设备的位置信息。
本公开中，步骤404-步骤405的具体实现过程，可参见本公开任一实施例的详细描述，在此不再赘述。
可以理解的是，由于TA补偿值T TA可以表征终端设备与卫星间的距离，本公开中基于当前卫星的第二位置信息，分别与终端设备移动前后的位置信息，确定两次TA补偿值，进而再确定TA变化值，由于该TA变化值，是基于卫星的同一位置信息确定的，即未考虑卫星位置的变化，从而使得判断是否满足位置信息上报条件时，仅考虑了终端设备位置变化，而未考虑卫星的位置变化，有效避免了终端设备位置未变化，仅卫星位置变化触发的位置信息上报，而造成的资源浪费。
本公开中，终端设备可以根据终端设备当前对应的第一位置信息及卫星当前对应的第二位置信息，确定第一TA补偿值，并根据终端设备前一次上报的第三位置信息及第二位置信息，确定第二TA补偿值，之后，可以根据第一TA补偿值与第二TA补偿值间的差值，确定TA变化值，在终端设备对应的定时提前TA变化值大于门限值的情况下，向网络设备上报终端设备的位置信息。由此，通过基于卫星当前的位置信息，及终端设备移动前后的位置信息，确定TA变化值，有效剔除了因卫星移动导致的TA变化值部分，从而避免仅因卫星移动触发位置信息上报的现象，有效地避免资源的浪费。
请参见图5，图5是本公开实施例提供的一种位置信息的上报方法的流程示意图，该方法由终端设备执行。如图5所示，该方法可以包括但不限于如下步骤：
步骤501，根据终端设备当前对应的第一位置与前一次上报位置信息时卫星对应的第四位置，确定第三TA值。
其中，第一TA值是根据终端设备位置与卫星位置的，所以第一TA值为服务链路service link对应的TA值，也就是终端设备特有specific定时提前TA值。
本公开中，终端设备可以根据卫星对应的星历，确定卫星当前对应的位置信息，或者，也可以根据其他终端设备或者网络设备的指示，确定位置信息，本公开对此不做限定。
本公开中，终端设备可以在上报位置信息时，记录下对应的终端设备的位置信息及卫星的位置信息，进而即可在当前时刻根据记录的前一次上报位置信息时对应的卫星的第四位置信息及当前终端设备对应的第一位置信息，计算出第三TA值。
步骤502，根据终端设备前一次上报的第三位置信息及第四位置信息，确定第四TA值。
本公开中，终端设备可以根据在当前时刻根据记录的前一次上报的终端设备的第三位置信息及卫星的第四位置信息，计算出第四TA值。
步骤503，根据第三TA值与第四TA值间的差值，确定TA变化值。
本公开中，可以将第三TA值与第四TA值进行做差，之后，可以将此差值确定为终端设备对应的TA变化值。
步骤504，确定终端设备对应的定时提前TA变化值大于门限值。
步骤505，向网络设备上报终端设备的位置信息。
本公开中，步骤504-步骤505的具体实现过程，可参见本公开任一实施例的详细描述，在此不再赘述。

本公开中，考虑到在NTN网络中，由于卫星的覆盖范围较大，网络设备需要知道终端设备的位置信息才能为终端设备选择合适的接入和移动管理功能(authentication management function，AMF)，从而需要终端设备在满足触发条件或者周期性的上报其位置信息。而由于终端设备的移动或者卫星的移动，都可能使得终端设备满足上报位置信息的触发条件，从而导致资源浪费，为了避免终端设备没有移动，仅因卫星在移动，造成TA变化值大于门限值，而触发位置信息上报的现象，本公开可以剔除因卫星移动对TA变化值的影响，仅保留因终端设备的位置变化引起的TA变化值，并在终端设备对应的由自身位置变化引起的定时提前TA变化值大于门限值的情况下，向网络设备上报终端设备的位置信息。

其中，配置信息可以包括以下任一项：TA变化值的描述信息、上报位置信息的周期值、及基于媒体接入控制(media access control control element，MAC CE)控制单元的TA报告配置信息。
