其中，GNSS测量到的终端设备的GNSS位置信息，用于确定定时提前量(Timing Advance，TA)，以对卫星通信中，上行传输中的传输时延进行补偿。
本申请实施例中，终端设备可以对当前GNSS位置信息的有效期进行监控，以确定当前GNSS位置信息是否到期，在当前GNSS位置信息到期后，若继续基于当前GNSS位置信息，确定TA，由于当前GNSS位置信息已经失效，进而会导致确定的TA与实际的TA存在差异，使得终端设备与网络设备之间不能更好地进行同步，导致不同的终端设备之间可能存在上行传输干扰的问题。
为了提高信息或数据传输的准确性，本申请实施例中需要及时更新终端设备的GNSS位置信息，从而能够获取到精准的TA，也就是说，需要在终端设备当前GNSS位置信息到期时，重新确定终端设备的GNSS位置信息，即需要终端设备重新进行GNSS测量。终端设备可以在进入到闲置状态(空闲态)后重新进行GNSS测量，但是终端设备进入闲置状态的GNSS测量会带来不必要的时延和电量消耗，为了及时有效地获取终端设备的GNSS位置信息，本申请实施例中，可以引入新的机制，在终端设备处于连接态时重新进行GNSS测量，即在重新进行GNSS测量时，终端设备无需进入闲置状态，可以继续保持在连接状态，由于终端设备处于连接状态可以提高GNSS测量的时效性。
其中，终端设备的GNSS位置信息的有效期可以为预先定义的，也可以为网络设备通过系统信息或信令通知给终端设备的。在一些实现中，网络设备可以通过RRC信令将GNSS位置信息的有效期通知给终端设备；在另一些实现中，网络设备可以通过MAC层控制单元(MAC Control Element，MAC CE)信令将GNSS位置信息的有效期通知给终端设备；在又一些实现中，网络设备可以通过物理层信令将GNSS位置信息的有效期通知给终端设备。
