下面参考附图对本公开提供的用于辅助小区重选的重选时间确定方法、装置及通信设备进行详细描述。
图1为本公开实施例所提供的一种用于辅助小区重选的重选时间确定方法的流程示意图，应用于用户设备UE。
如图1所示，包括以下步骤：
步骤101，接收网络侧设备发送的用于辅助UE进行小区重选的时间信息，并根据时间信息确定重选时间。
步骤102，在重选时间进行邻小区测量，以进行小区重选。本公开实施例中，用户设备为地面接收机，该地面接收机可以为移动接收机或者是固定的接收机，用于接收各个卫星的信号，本实施例中不进行限定。网络侧设备可以为卫星网关，或者是和卫星网关通信的5G基站，对于网络侧设备，本实施例中不进行限定。
本公开实施例的一种实现方式中，时间信息包括以下至少一项：
服务小区停止服务的系统帧号K；
时长T2，其中，时长T2为服务小区能够提供的服务时间；
协调世界时UTC时间T3；
星历时间T4。
本公开实施例中，根据获取的系统帧号相关的时间信息，确定NTN小区对某个区域停止服务时的系统帧号K，其中，系统帧号的编号为0-1023，每一帧为固定时长的帧，例如为10ms，每一个循环中系统帧号从0-1023，即经过1024*10ms＝10.24秒，完成一次帧循环。
时长信息为服务小区能够提供多少秒的服务时间，以10ms为单位计数服务的时长。协调世界时(Universal Time Coordinated，UTC)时间T3，又称为世界统一时间，此时间以公历为单位自1900年1月1日的00:00:00开始，以10毫秒为单位计算UTC秒数，以得到协调世界时间T3。星历时间T4是卫星的星历，能精确计算、预测、描绘、跟踪卫星、飞行体的时间等运行状态，包括星历参考时间(Ephemeris reference time)和时长，该时长表示在当前星历参考时间T4之后的时长内，能够给某个区域提供服务。作为一种实现方式，星历参考时间，根据UTC时间确定。
本公开实施例中，各个卫星在绕地球飞行时，各个卫星对于地面区域的服务范围会发生变化，也就是说针对地面的用户设备，卫星的绕地飞行，会使得用户设备和某个卫星的服务小区通信链路断开，因此，需要进行小区重选，即重新选择服务的卫星或卫星的不同小区。而通常在进行小区重选时，采用S准则进行选择，其中，S准则是用户设备连续测量接收到的不同的卫星的通信信号的信号功率Srxlev和信号质量Squal，确定信号功率Srxlev和信号质量Squal均大于阈值的卫星，并在检测到卫星的信号功率和信号质量Squal持续大于阈值达到设定时长时，切换至该卫星对应的服务小区，以实现小区重选。然而S准则的选择方式，耗时较久，存在当进行小区切换时，选择的场强信号最强的卫星已经运行至用户设备无法接收到信号的位置，导致小区重选过晚，使得用户设备和卫星的通信链路断开，影响了用户设备的正常使用。因此，本公开实施例中，用户设备根据从网络侧设备获取的上述的时间信息中的至少一个，确定UE进行邻小区测量的重选时间，在重选时间进行邻小区测量，以进行小区重选，实现了确定了用于辅助UE进行小区重选的时间信息的具体内容，提高了小区重选的可靠度，避免了通信链路的断开。
本公开实施例的用于辅助小区重选的重选时间确定方法，用户设备接收网络侧设备发送的用于辅助UE进行小区重选的时间信息，并根据时间信息确定重选时间，在重选时间进行邻小区测量，以进行小区重选，本公开实施例中确定了用于辅助UE进行小区重选的时间信息的具体内容，便于用户设备根据 时间信息确定重选时间，提高了小区重选的可靠度，避免没有网络覆盖。
上述实施例中说明了用于辅助UE进行小区重选的时间信息包含多个，而根据各个时间信息确定重选时间的方法不同，下面采用不同的实施例进行具体说明。
基于上述实施例，本实施例中，根据时间信息为服务小区停止服务的系统帧号K，说明如何确定重选时间。图2为本公开实施例提供的另一种用于辅助小区重选的重选时间确定方法的流程示意图，如图2所示，该方法包含以下步骤：
步骤201，接收网络侧设备发送的用于辅助UE进行小区重选的服务小区停止服务的系统帧号K。
本公开实施例中，当时间信息为服务小区停止服务的系统帧号K时，系统帧号包括以下参数：系统帧号循环次数M；系统帧号偏移量N和系统消息更新周期数L。
作为一种实现方式，系统帧号为0-1023，系统帧号循环次数M为1，即1次系统帧号循环表示经历了1024个系统帧。
在本公开实施例的一种实现方式中，当时间信息为服务小区停止服务的系统帧号K时，还包括的参数为系统帧号循环次数M和系统帧号偏移量N，则当前服务小区能够提供的服务时长P，可通过以下的公式确定：
P＝M*10.24+N/100-K/100(秒)。
其中，系统帧号偏移量N的取值范围为0-1023，此时N需要10个比特bit表示。
在本公开实施例的另一种实现方式中，当时间信息为服务小区停止服务的系统帧号K时，还包括的参数为系统帧号循环次数M，系统帧号偏移量N和系统消息更新周期数L。则当前服务小区能够提供的服务时长P，可通过以下的公式确定：
P＝M*10.24+L*Q/100+N/100-K/100(秒)，其中，Q为系统周期更新长度。作为一种实现方式，系统周期更新的长度可以用无线帧的个数来表示，例如，系统周期更新长度为3个无线帧的时长。
其中，系统帧号偏移量N小于上一种实现方式中N的取值范围，系统消息更新周期数L可以表示部分系统帧号偏移量。
本公开实施例的一种实现方式中，系统帧号循环次数M是用户设备从网络侧设备获取到的系统消息中得到的。例如，用户设备接收到网络侧设备在系统帧号为0帧时发送的系统消息，那么用户设备还会接收到网络侧设备在下个系统帧号为0帧时更新的系统消息，其中，系统消息中包含了需要更新的系统帧号循环次数M，也就是说其中，L、Q、K和N可以不在系统消息中更新，而循环次数M在更新过程中不断减小，例如，第一个系统帧号循环周期内系统帧号循环次数为M，则下一个系统帧号循环周期内的系统循环帧号次数为M-1。
本公开实施例中，以根据服务小区停止服务的系统帧号K，系统帧号循环次数M，系统帧号偏移量N和系统消息更新周期数L计算得到服务时长P为例进行说明。例如，1次系统帧号循环表示经历了1024个系统帧，服务小区停止服务的系统帧号K为1000帧时，系统帧号偏移量N为120帧，系统消息更新周期数L为2，Q为系统周期更新长度为70帧，接收到的网络侧设备发送的首个系统消息中循环次数M为4次，从而当前服务小区能够提供的服务时长P＝4*1024/100+2*70/100+120/100-1000/100(秒)；而服务小区可提供的服务时长是不断减少的，下一次接收到的网络侧设备发送的系统消息中循环次数M减小，变为3次，从而当前服务小区能够提供的服务时长P＝3*1024/100+2*70/100+120/100-1000/100(秒)；依次类推，最后一次接收到的网络侧设备发送的系统消息中循环次数M则减为0次，从而当前服务小区能够提供的服务时长P＝0*1024/100+2*70/100+120/100-1000/100(秒)。
其中，P根据服务小区停止服务的系统帧号K时，系统帧号循环次数M和系统帧号偏移量N计算得到时，其中，M的循环次数的变化原理相同，本实施例中不再赘述。
本公开的实施例中，网络至少在每个系统帧号(System Frame Number，SFN)循环周期内更新一次参数。网络通过系统信息发送参数，则网络需要在每个系统信息更新周期更新参数。假设网络上次通过系统信息发送的时长为L，则更新周期内发送的时长为L-系统信息更新周期长度。通常，网络在每次更新星历参数时间时更新时长。其中，网络在对某区域停止服务之间不需要更新时间参数。
步骤202，根据服务小区停止服务的系统帧号K确定UE进行邻小区测量的重选时间。
本公开实施例中，获取服务时长P的起始时间，并作为第一时间，根据第一时间、服务时长P和时间偏移量确定UE进行邻小区测量的重选时间。其中，时间偏移量，是由网络侧设备发送或者协议规定的，而在网络侧设备未发送或者是协议未规定的情况下，时间偏移量则为0。
针对重选时间的确定，在本公开实施例的一种实现方式中，重选时间＝第一时间T1+服务时长P-时间偏移量Toffset。
步骤203，在重选时间进行邻小区测量，以进行小区重选。
在本公开实施例的一种实现方式中，在重选时间进行邻小区测量，在小区重选的过程中，可以获取各个卫星的星历信息，结合星历信息中各个卫星可服务用户设备的开始时间和结束时间，进行小区重选，提高小区重选的可靠性。
本公开实施例的用于辅助小区重选的重选时间确定方法中，用户设备接收网络侧设备发送的用于辅助UE进行小区重选的时间信息，并根据时间信息确定重选时间，当时间信息为服务小区停止服务的系统帧号K时，根据系统帧号循环次数M、系统帧号偏移量N和系统消息更新周期数L，确定当前服务小区能提供的服务时长P，进而，根据服务时长P的起始时间、服务时长P和时间偏移量确定UE进行邻小区测量的重选时间，本公开实施例中确定了用于辅助UE进行小区重选的时间信息的具体内容，便于用户设备根据时间信息确定重选时间，提高了小区重选的可靠度，避免没有网络覆盖。
基于上述实施例，本实施例中，根据时间信息为时长T2，说明如何确定重选时间。图3为本公开实施例提供的另一种用于辅助小区重选的时间确定方法的流程示意图，如图3所示，该方法包含以下步骤：
步骤301，接收网络侧设备发送的用于辅助UE进行小区重选的时长T2。
其中，时长T2为服务小区能够提供服务的时长T2，也就是说服务小区还可以给用户设备提供服务的时间。
步骤302，获取时长T2对应的第二时间，根据第二时间、服务时间和时间偏移量确定重选时间。
其中，服务时间为时长T2为服务小区能够提供的服务时间。时间偏移量是网络侧设备设定的或者是协议规定的时间裕量。
本公开实施例中，获取时长T2对应的第二时间，其中，第二时间是获取时长T2的起始时间，可记为第二时间T2，从而，作为一种实现方式，根据用户设备获取时长T2对应的起始时间即第二时间T2，加上服务小区当前还能服务的服务时间T1，再减去时间偏移量Toffset，以得到重选时间对应的时刻。

步骤402，根据UTC时间T3和时间偏移量确定重选时间。
其中，时间偏移量是网络侧设备或协议规定的测量UTC时间T3预留的时间裕量。当网络侧设备或协议未规定的情况下，时间偏移量则为0，即根据UTC时间T3，确定重选时间。
在时间偏移量由网络侧设备或协议规定的情况下，下面采用不同的实现方式，分别说明确定重选时间的方式。
本公开实施例的第一种实现方式中，根据获取网络侧设备通过系统信息块(System Information Block，SIB9)发送的系统UTC时间，为了便于区分，称为T5，其中，SIB9中的数字9是指SIB中的一个编号，当系统UTC时间T5与UTC时间T3之间的时间差小于或等于时间偏移量时，将系统UTC时间T5作为重选时间。

其中，时间偏移量由网络侧设备发送或者协议规定。
本公开实施例中，在网络侧设备没有配置或者是协议未规定的情况下，时间偏移量为零，从而，根据第二星历参考时间T8和时长T9生成重选时间。
本公开实施例的一种实现方式中，在网络侧设备发送或者协议规定了时间偏移量的情况下，重选时间是根据第二星历参考时间T8，加上时长T9，再减去时间偏移量计算得到的。
进一步，在本公开实施例的一种实现方式中，星历时间T4之中的时长T9在每次更新星历参考时间时会进行更新，也就是说星历参考时间在更新后，时长T9也会更新。而更新后的时长T9为在每次更新星历参考时间后得到的对应的新的时长。进而，根据每次更新星历参考时间后得到的对应的新的时长T9，确定重选时间，提高了重选时间确定的准确性。
步骤503，在重选时间进行邻小区测量，以进行小区重选。
具体地，可参照前述方法实施例中的解释说明，原理相同，本实施例中不再赘述。

本公开实施例中，时长T2为用户设备从网络侧设备发送的系统消息中获取到的，从而网络侧设备在每个系统消息更新周期对时长T2进行更新，以保证时长T2的准确性。由于用户设备从网络侧设备获取系统消息需要时间，也就是说用户设备需要等待系统消息更新周期的时长，才能获取到系统消息，从而，时长T2为在系统消息更新周期更新后的时长T2，例如，用户设备从网络侧设备发送的系统消息中获取得到的时长T2＝L，系统消息更新周期的长度为X，则在系统消息更新周期更新后得到的时长信息为T2＝L-X。进而，根据每次系统消息更新周期后更新的时长T2，确定重选时间，提高了重选时间确定的准确性。
