为了方便理解本公开实施例，下面介绍与本公开实施例相关的术语或背景：
(1)非地面网络(Non-terrestrial Network，NTN)
NTN网络是指通过卫星作为通信中转，通过无线方式连接终端和基站。NTN网络可以提升网络侧覆盖，针对沙漠，海洋等场景，为终端提供连续覆盖。
图1是本公开提供的NTN网络示意图，如图1所示，以5G场景下的一个NTN网络为例，其中NTN卫星与终端之间是服务链路，NTN卫星与NTN网关之间叫做馈电链路。为了便于理解，我们视NTN卫星和NTN网关为下一代基站(next generation NodeB，gNB)的一部分。
基于该网络架构，NTN卫星将来自于基站的数据透明转发给终端，同理终端的数据也通过NTN卫星透明转发给NTN网关和基站。
其中一个gNB可以服务多个NTN卫星；而一个NTN卫星也可以被多个gNB服务。在目前的NTN网络中，NTN卫星可以在服务链路上改变载波频率后，再执行数据发送。
NTN网络包含以下3种服务链路：
地表固定小区(Earth-fixed cell)：即NTN卫星覆盖的小区是一直是不变的，如同步轨道(Geostationary Orbit，GEO)卫星在地面投射的小区；
准地表固定小区(Quasi-Earth-fixed cell)：即卫星的波束(beam)在一段时间内稳定的覆盖某一片地表固定区域；
地表移动小区(Earth-moving cell)：这种场景下，卫星的波束(beam)覆盖范围是在地球表面滑动的。
(2)物联网(Internet of Things，IoT)NTN技术
IoT NTN技术，目标是让IoT设备，主要是窄带物联网(Narrow Band-Internet of Things，NBIoT)设备或者基于长期演进(Long Term Evolution，LTE)的物联网技术(LTE enhanced MTO，eMTC)设备，能够接入卫星网络。
在相关技术中，主要研究的场景是，较短连接的场景，在这样的场景下，全球导航卫星系统(Global Navigation Satellite System，GNSS)位置有效定时器超时后，终端设备(User Equipment，UE)就可以进入空闲态。
UE重新获取GNSS信息，但是不能同时支持GNSS获取以及NTN NB-IoT/eMTC操作，即不能支持UE在连接态获取GNSS信息并且保持NTN  NB-IoT/eMTC通信。那么，如果NB-IoT/eMTC设备需要进行GNSS位置的再获取，就需要中断NB-IoT/eMTC的通信过程。因此，目前的技术中不支持UE在连接态获取GNSS信息。
因此一般终端的行为是在接入一个小区之前，执行GNSS信息获取操作，同时通过无线资源控制(Radio Resource Control，RRC)连接设置完成(RRC Connection Setup Complete，也称为msg5)向接入网侧(如基站)上报剩余GNSS有效期(remaining GNSS validity duration)。
但是，目前的IoT NTN技术需要针对更广泛的场景支持长连接的情况，也就是，IoT NTN设备将有较长一段时间处于连接态。
但是当终端处于连接态时，终端也可以通过其他方式获取GNSS，例如配置间隔(gap)的方式。当终端获取GNSS后，同样需要将remaining GNSS validity duration上报给网络侧，但是目前还没有任何上报机制。
本公开实施例提供一种定时信息更新的方法，可以用于终端在连接态获取GNSS信息后，向接入网上报剩余GNSS有效期。
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，并不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图2是本公开实施例提供的定时信息的更新方法的流程示意图之一，如图2所示，本公开实施例提供一种定时信息的更新方法，应用于终端，包括：
步骤210，所述终端获取全球导航卫星系统GNSS信息；
具体地，终端可以通用终端设备，也可以是IoT终端设备(参考上文介绍的IoT设备)，终端可以处于连接态或空闲态。应理解，以上为便于理解本公开实施例进行的举例，本公开实施例对终端的类型不做限定。
以连接态的终端为例，连接态的终端可以通过停止数据传输的方式，维持终端与网络之间的RRC连接，在连接态获取GNSS信息，GNSS信息可以包括GNSS位置、伪距和伪距率、导航消息、累计变化量或载波、或硬件时钟信息等。终端可以通过GNSS测量获取GNSS信息。
示例性地，可以设置间隔时间，终端可以在所述间隔时间内停止与网络的数据传输，进行GNSS测量，获取GNSS信息，在间隔时间到时前，完成GNSS信息获取，间隔时间到时后，恢复数据传输，从而实现维持与网络之间的RRC连接，并完成GNSS信息获取。应理解，以上是为便于理解本公开实施例进行的举例，不应对本公开构成任何限定，如终端获取GNSS信息的方式可以参考其他相关技术，此处不再赘述。
终端可以在GNSS位置有效定时器超时后获取GNSS信息，也可以在接收到接入网实体发送的指示后获取GNSS信息，应理解，以上是为便于理解本公开实施例进行的举例，本公开实施例对终端何时进行GNSS信息获取不作限定。
步骤220，所述终端确定剩余GNSS有效期；
具体地，所述剩余GNSS有效期可以由终端根据终端的能力确定，如终端设备的硬件(如移动传感器、位置传感器和环境传感器等)参数、与终端进行通信的卫星的硬件参数等。剩余GNSS有效期(remaining GNSS validity duration)可以指当前获取的GNSS信息的剩余的有效时间。
剩余GNSS有效期可以用于更新GNSS位置有效定时器。
步骤230，所述终端在确定满足上报条件的情况下，向接入网实体发送所述剩余GNSS有效期。
具体地，上报条件可以根据终端情况和/或网络情况确定，终端情况可以包括终端业务、终端移动轨迹等，如终端业务所需的服务时间、终端需要处理的数据量；网络情况可以包括如小区承载、小区繁忙程度、网络支持的业务等。上报条件可以是网络侧预先配置的、协议约定的或网络侧向终端发送的；上报条件可以是静态设置的，也可以由用户(如运营商)动态设置。本公开实施例对终端如何获知上报条件、上报条件的设置方式以及上报条件的具体内容等不作限定。
在确定满足上报条件的情况下，向接入网实体发送所述剩余GNSS有效期，是指终端确定满足上报条件，向接入网实体发送所述终端确定的剩余GNSS有效期。
示例性地，终端可以在确定满足上报条件的同时向接入网实体发送所述剩余GNSS有效期；终端可以在确定满足上报条件之后的预定义时间内向接入网实体发送所述剩余GNSS有效期；也可以在确定满足上报条件且触发预定义事件后，向接入网实体发送所述剩余GNSS有效期。应理解，以上是为便于理解本公开实施例进行的举例，不应对本公开构成任何限定，本公开实施例对终端向接入网实体发送所述剩余GNSS有效期的具体时间不作限定，只要在确定满足上报条件的情况下即可。
终端确定剩余GNSS有效期后，连接态的终端可以在保持与网络通信的状态(连接态)下，向接入网实体发送所述终端确定的剩余GNSS有效期。
本公开实施例提供的定时信息的更新方法，通过终端向接入网实体上报剩余GNSS有效期(remaining GNSS validity duration)，实现了网络侧和终端侧的定时信息(剩余GNSS有效期)的同步更新，尤其可以适用于终端在连接态获取GNSS信息后，上报剩余GNSS有效期，实现定时信息同步更新。并且通过终端判断是否满足条件后，在满足条件的情况下，向接入网实体发送所述剩余GNSS有效期，根据上报条件设置的不同，可以实现及时上报或可以节约资源等效果，如可以避免不需要更新定时信息的情况下上报剩余GNSS有效期导致的资源浪费。
可选地，所述上报条件包括以下任一或其组合：
当前小区剩余的服务时间大于所述剩余GNSS有效期；
接收到接入网实体发送的、用于指示所述终端上报所述剩余GNSS有效期的上报指示消息；
所述终端的数据量大于上报门限；
通过预设数据无线承载DRB接收到数据；
通过预设服务质量QoS流接收到数据；
所述GNSS信息有效。
具体地，对于当前小区剩余的服务时间大于所述剩余GNSS有效期，当前小区是指终端当前所接入的小区；对于当前小区剩余的服务时间，应理解，在应用中，终端一般都是动态随机的到达和离开一个小区，终端会在各个小 区中以不同的服务时间保持活跃，服务时间可以理解为当前小区为终端提供服务的时间，剩余的服务时间可以理解为当前小区剩余的、为终端提供的服务时间，或者可以理解为终端在切换至下一个小区之前，当前小区能够为终端提供服务的时间。剩余的服务时间可以与终端的活动轨迹、当前小区能够为终端提供的业务类型、终端所需的业务类型或当前小区能够为终端提供的资源等相关。
应理解，以上是为便于理解本公开实施例进行的举例，当前小区剩余的服务时间的概念和计算可以参考相关技术，如通信协议标准，此处不再赘述。
可选地，终端判断所述当前小区剩余服务时间的方法包括但不限于以下任一或其组合：
读取卫星的广播消息，获得当前小区剩余服务时间t-ServingTime；
终端根据卫星速度，终端速度、卫星的位置信息以及终端的位置信息进行计算获得。
所述卫星是指与所述终端相连的NTN卫星。
本公开实施例提供的定时信息的更新方法，通过终端在当前小区剩余的服务时间大于所述剩余GNSS有效期的情况下，向接入网实体发送所述剩余GNSS有效期，可以节约资源。应理解，在当前小区剩余的服务时间小于等于所述剩余GNSS有效期的情况下，终端上报的GNSS信息可以保证在终端切换至新的小区之前是有效的，并且在所述剩余GNSS有效期到期前，终端可能已经切换至新的小区，上报所述剩余GNSS有效期会导致资源浪费。
对于所述终端的数据量大于上报门限，终端的数据量是指终端需要进行传输/处理的数据量，上报门限预先设定的，上报门限可以为协议规定的、网络侧预先配置的或者网络侧通知的，本公开实施例对上报门限如何设置以及具体门限数值不作限定。
可选地，上报门限数值的设置可以与传输或处理的数量所需的时间有关。
本公开实施例提供的定时信息的更新方法，通过在终端的数据量大于上报门限情况下，终端向接入网实体发送所述剩余GNSS有效期，可以节约资源。应理解，在终端的数据量大于上报门限情况下，终端可能剩余GNSS有 效期到期前，无法完成传输/处理所述数据，因此需要向网络侧上报所述剩余GNSS有效期；而在终端的数据量小于等于上报门限情况下，终端可以在剩余GNSS有效期到期前，完成传输/处理所述数据，因此无需上报所述剩余GNSS有效期，实现资源节约。
对于通过预设数据无线承载(Data Radio Bearer，DRB)接收到数据以及通过预设服务质量(Quality of Service，QoS)流接收到数据：
DRB是用于传输接入网实体(如基站)与终端UE之间的业务数据的承载。DRB是用户数据实际传输的通道。QoS与DRB之间可以实现映射。示例性地，LTE中，根据QoS不同，终端与基站之间可同时最多建立8个DRB。
可以预先设置DRB或QoS流，当从预设的DRB承载上的数据到达终端时，或者由预设的QoS流映射的DRB承载上的数据到达终端时，终端向接入网实体上报所述剩余GNSS有效时间。
可选地，所述DRB或QoS流可以为网络预先配置的、协议约定或网络通知的，应理解，以上是为便于理解本公开进行的举例，本公开实施例对DRB或QoS流如何预设不作限定。
本公开实施例提供的定时信息的更新方法，在通过预设DRB或QoS流接收到数据的情况下，终端向接入网实体发送所述剩余GNSS有效期，可以节约资源。应理解，预设的DRB或QoS流可以用于传输需要GNSS信息的数据，在预设的DRB或QoS流上接收到数据时，说明网络侧需要剩余GNSS有效期，此种情况下上报剩余GNSS有效期，可以节约资源。
对于接收到接入网实体发送的、用于指示所述终端上报所述剩余GNSS有效期的上报指示消息，接收到接入网实体发送的上报指示消息后，根据上报指示消息向接入网实体发送剩余GNSS有效期。
具体地，可以由接入网实体判断是否需要上报剩余GNSS有效期，在接入网实体判断需要上报剩余GNSS有效期，指示终端上报所述剩余GNSS有效期。可选地，接入网实体可以结合当前小区剩余的服务时间、接入网实体需要向终端传输的数据量或预设的DRB承载/QoS流上的是否有数据等判断是否需要上报剩余GNSS有效期。应理解，以上是为便于理解本公开进行的 举例，本公开实施例对网络侧(接入网)的判断标准不做限定。
本公开实施例提供的定时信息的更新方法，通过是否接收接入网实体发送的、用于指示所述终端上报所述剩余GNSS有效期的上报指示消息，来判断是否上报剩余GNSS有效期，无需每次都上报剩余GNSS有效期，节约了资源。
对于所述GNSS信息有效是指获取的GNSS信息是有效的，不存在GNSS信息错误或GNSS过期等情况。
本公开实施例提供的定时信息的更新方法，在GNSS信息有效的情况下，上报剩余GNSS有效期，避免了获取无效GNSS信息后，上报无效GNSS信息所对应的剩余GNSS有效期，避免了资源浪费。
可选地，所述上报条件可以为：获取全球导航卫星系统GNSS信息和/或GNSS位置有效定时器。
本公开实施例提供的定时信息的更新方法，在获取全球导航卫星系统GNSS信息后和/或GNSS位置有效定时器超时的情况下，上报剩余GNSS有效期，保证了剩余GNSS有效期上报的及时性和有效性。
应理解，以上各个条件可以相互组合，组合的情况以及对应的效果，参考上述介绍，此处不再赘述。

可选地，可以由接入网实体先向终端发送的第一MAC CE，所述第一MAC CE可以指示终端获取GNSS信息；终端获取GNSS信息后，向接入网实体上报第二MAC CE，第二MAC CE中携带所述剩余GNSS有效期。
可选地，定义第一定时器，当终端在上行(Uplink，UL)授权发送第二MAC CE后，打开第一定时器；
可选地，当第一定时器超时后，终端将重新触发第二MAC CE，更新剩余GNSS有效期remaining GNSS validity duration后，在后续可用的UL授权上发送。
可选地，当没有UL授权资源时，终端可以触发调度请求(Scheduling request，SR)或随机接入过程，发送第二MAC CE。
可选地，可以为第二MAC CE预定义逻辑信道标识(IDentity，ID)。预定义可以为网络配置的、网络通知的或协议约定的，应理解，以上是为便于理解本公开实施例进行的举例，本公开实施例对终端和接入网实体如何预定义逻辑信道ID不作限定。
可选地，在所述终端重新获取GNSS信息或已发送与当前GNSS信息对应的剩余GNSS有效期的情况下，取消向所述接入网实体发送所述MAC CE消息。
具体地，当终端收重新获取GNSS信息时或已经发送第二MAC CE，取消第二MAC CE的触发，从而减少MAC CE的重复发送。
对于所述终端通过无线资源控制RRC消息向所述接入网实体发送所述剩余GNSS有效期的情况，是指终端与网络保持通信，终端向网络发送RRC消息，在RRC消息中携带剩余GNSS有效期。
可选地，可以由接入网实体先向终端发送的第一RRC消息，所述第一RRC消息可以为请求消息，终端向接入网实体发送第二RRC消息，第二RRC消息中携带所述剩余GNSS有效期，第二RRC消息可以响应消息。

切换完成Handover complete消息；
测量报告消息；
新定义的RRC消息。
对于RRC消息为切换完成Handover complete消息的情况，可以为：
在所述终端为机器类型通信(Machine Type Communication，MTC)类型设备的情况下，所述向接入网实体发送剩余GNSS有效期包括：
基于切换完成消息向所述接入网实体发送所述剩余GNSS有效期。
示例性地，如果终端是MTC类型，如果在切换前终端判断：终端在当前小区剩余的服务时间大于剩余GNSS有效期remaining GNSS validity duration，终端可以在发送切换完成Handover complete消息时，发送剩余GNSS有效期remaining GNSS validity duration。
对于RRC消息为新定义的RRC消息的情况：新定义的RRC消息，是指重新定义的第二RRC消息，可以专门用于GNSS信息上报的RRC消息，例如GNSS响应GNSSResponse消息。
对于RRC消息为测量报告消息的情况：测量报告消息是指用于向接入网实体发送测量报告的RRC消息，所述测量报告消息中携带有测量报告，所述测量报告可以为GNSS测量报告，所述测量报告中携带有所述剩余GNSS有效期。
可选地，所述方法还包括：所述终端向所述接入网实体发送用于指示所述剩余GNSS有效期的起始时间的时间戳。
具体地，时间戳用于指示剩余GNSS有效期remaining GNSS validity duration的起始时刻。时间戳可以是终端从所述终端连接的NTN卫星获得的。NTN卫星可以作为时间接收设备来获取时间到时间戳服务器上，并通过时间戳服务器向终端签发时间戳证书。时间戳可以用于同步终端和接入网实体的对剩余GNSS有效期的理解。
示例性地，终端和接入网实体发送了无线链路层控制协议(Radio Link Control，RLC)重传或混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)重传，导致终端和接入网实体对于时间的理解不同，终端上报的剩余GNSS有效期为25分钟，是指从12:00:00开始剩余25分钟，而接入网实 体理解为从11:55:00开始剩余25分钟。加入时间戳后，接入网实体可以获知剩余GNSS有效期从终端上报的时间戳所指示的时间开始计时。
可选地，时间戳可以由终端向接入网实体发送的RRC消息(第二RRC消息)携带。
本公开实施例提供的定时信息的更新方法，通过上报时间戳，可以有效避免由于RLC重传或HARQ重传造成终端和基站对于剩余GNSS有效期remaining GNSS validity duration理解不一致的问题。
可选地，所述方法还包括：

当终端获取GNSS信息后，如果触发了测量触发事件，终端向接入网实体上报测量报告，测量报告包含剩余GNSS有效期remaining GNSS validity duration。
可选地，测量报告可以由测量报告消息携带。
本公开实施例提供的定时信息的更新方法，通过设置测量触发时间触发剩余GNSS有效期上报，并通过测量报告向接入网实体发送所述剩余GNSS有效期，可以实现完成测量后，如完成GNSS测量后，通过测量报告向接入网实体发送所述剩余GNSS有效期，无需单独使用其他信令进行剩余GNSS有效期发送，节省信令资源，并且能够保证剩余GNSS有效期上报的及时性。
可选地，所述方法还包括：
所述终端接收所述接入网实体发送的第一指示消息，所述第一指示消息 携带有用于指示终端执行GNSS获取的配置信息；

终端可以根据接入网实体发送的配置信息进行GNSS测量，获取GNSS信息。
可选地，所述配置信息包括以下任一或其组合：
间隔时间的周期；
间隔时间的时间长度；
间隔时间的起始时间；
其中，所述间隔时间用于指示终端获取所述GNSS信息的时间长度。
具体地，间隔时间GAP用于GNSS测量GAP。GNSS测量GAP(measurement gap)是指即预留一部分时间进行GNSS测量，所述预留的一部分时间即为测量GAP时间，本公开实施例中称为间隔时间，本公开实施例对名称不作限定，能够限定GAP时间即可。在测量GAP时间内，UE不会发送和接收任何数据，UE将接收机调向GNSS测量频点，进行GNSS测量，测量GAP时间结束时再转到当前小区的频点。
具体地，间隔时间的周期，可以在GAP的周期，即每隔一段时间(周期)产生一段间隔时间GAP，间隔时间GAP用于GNSS测量。
间隔时间的时间长度是指间隔时间GAP持续的时间。
间隔时间的起始时间是指间隔时间GAP开始的时间。
可选地，间隔时间的周期，间隔时间的时间长度，间隔时间的起始时间，可以有默认的预设值，当配置信息中未包含相应信息的情况下，使用默认的预设值。
示例性地，周期为60s，时间长度为10s，起始时间为00:00:00，则从起 始时间为00:00:00开始，00:00:00-00:00:10进行GNSS测量，00:00:10-00:01:10，停止GNSS测量，00:01:10-00:01:20，重新进行GNSS测量，如此循环更新GNSS信息。
可选地，所述终端接收所述接入网实体发送的第一指示消息，之前还包括：
所述终端向所述接入网实体发送第一信息，所述第一信息包括以下任一或其组合：
终端获取GNSS信息的最大时间长度信息；
终端是否支持在连接态获取GNSS信息。
具体地，终端获取GNSS信息的最大时间长度信息是指终端进行GNSS获取(或GNSS测量)所需的最大时间长度。一个实施例中，终端可以根据终端设备的能力确定所述获取GNSS信息的最大时间长度信息；一个实施例中，终端可以历史测量过程中获取GNSS信息的所用的时间长度信息(如在历史值中找到最大值)作为获取GNSS信息的最大时间长度信息。
终端是否支持在连接态获取GNSS信息，是指连接态的终端是否能够获取GNSS信息。
本公开实施例提供的定时信息的更新方法，通过终端向所述接入网实体发送第一信息，使得接入网实体能够为终端准确配置用于GNSS获取的配置信息，避免间隔时间GAP过短导致终端无法获取有效的GNSS信息，也可以避免间隔时间GAP过长导致终端无法实时获得最新的GNSS信息，提高GNSS获取的有效性和效率。

对于上报条件的介绍，参考上文的介绍此处不再赘述。
本公开实施例提供的定时信息的更新方法，通过终端向接入网实体上报剩余GNSS有效期(remaining GNSS validity duration)，实现了网络侧和终端侧的定时信息(剩余GNSS有效期)的同步更新，尤其可以适用于终端在连接态获取GNSS信息后，上报剩余GNSS有效期，实现定时信息同步更新。并且通过终端判断是否满足条件后，在满足条件的情况下，向接入网实体发送所述剩余GNSS有效期，根据上报条件设置的不同，可以实现及时上报或可以节约资源等效果，如可以避免不需要更新定时信息的情况下上报剩余GNSS有效期导致的资源浪费。
可选地，所述接入网实体接收终端发送的剩余全球导航卫星系统GNSS有效期，之前还包括：
所述接入网实体向所述终端发送用于指示所述终端上报所述剩余GNSS有效期的上报指示消息。
具体地，可以由接入网实体判断是否需要上报剩余GNSS有效期，在接入网实体判断需要上报剩余GNSS有效期，指示终端上报所述剩余GNSS有效期。可选地，接入网实体可以结合当前小区剩余的服务时间、接入网实体需要向终端传输的数据量或预设的DRB承载/QoS流上的是否有数据等判断是否需要上报剩余GNSS有效期。应理解，以上是为便于理解本公开进行的举例，本公开实施例对网络侧(接入网)的判断标准不做限定。
本公开实施例提供的定时信息的更新方法，通过是否接收接入网实体发送的、用于指示所述终端上报所述剩余GNSS有效期的上报指示消息，来判断是否上报剩余GNSS有效期，无需每次都上报剩余GNSS有效期，节约了 资源。

步骤三：终端在GNSS有效定时器超时后，根据步骤二中配置的GNSS获取方式，获取GNSS信息；GNSS有效定时器用于计时可以用于计时已获取的GNSS信息剩余GNSS有效期，在已获取的GNSS信息剩余GNSS有效期超时后，获取新的GNSS信息。
步骤四：当终端重新获取GNSS信息后，如果触发了测量触发事件，终端向接入网实体上报测量报告，测量报告包含剩余GNSS有效期remaining GNSS validity duration。

可选地，第一指示消息可以是第一MAC CE。
步骤三：终端在接收到网络侧第一指示消息后，执行GNSS信息获取，并在获取GNSS信息后，触发第二MAC CE上报，并在存在UL授权时，向网络侧通过第二MAC CE上报剩余GNSS有效期remaining GNSS validity duration。
