Description

通信方法及装置、可读存储介质
本申请要求于2021年8月5日提交中国专利局、申请号为202110898504.X、发明名称为“通信方法及装置、可读存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及卫星通信技术领域，尤其涉及一种通信方法及装置、可读存储介质。
背景技术
在卫星通信中，存在非连续覆盖场景。例如，图1示出了一种非连续覆盖场景的示意图。如图1所示，卫星1在时间段1内为终端设备提供服务，卫星2在时间段2内为终端设备提供服务。而时间段1和时间段2之间间隔时间段3，即在时间段3内，没有卫星为终端设备提供服务。因此，在时间段3内，终端设备无法与卫星通信。
然而，现有技术中，终端设备在卫星通信中，延用现有无线通信系统中的监听方案，即终端设备需要在已确定的寻呼时机(paging occasion，PO)监听唤醒信号(Wake Up Signal，WUS)或者分组唤醒信号(Group WUS，GWUS)。由于卫星通信存在非连续覆盖场景，因此终端设备采用上述监听方式,监听期间可能存在没有卫星为终端设备提供服务的场景，因此容易导致资源浪费，终端设备功耗的增加。
发明内容
本发明解决的技术问题是提供一种通信方法及装置、可读存储介质，使终端设备可以降低耗能，节约资源。
本发明实施例提供一种通信方法，所述方法包括：终端设备确定寻呼时机；若所述寻呼时机位于第一时刻之前，所述终端设备在所述寻呼时机监听唤醒信号；其中，所述第一时刻为第一时间间隔的结束时刻，所述第一时间间隔为用于为所述终端设备提供服务的卫星位于第一小区的覆盖范围内的时间间隔，所述第一小区为所述终端设备的服务小区。
可选的，若所述寻呼时机为所述第一时刻，所述终端设备在所述寻呼时机不监听唤醒信号；或者，若所述寻呼时机位于所述第一时刻之后，所述终端设备在所述寻呼时机不监听唤醒信号。
可选的，所述第一时刻与所述寻呼时机之间的间隔大于或等于第一阈值。
可选的，若所述第一时刻与所述寻呼时机之间的间隔小于第一阈值，所述终端设备在所述寻呼时机不监听唤醒信号。
可选的，所述终端设备接收第一指示信息，所述第一指示信息用于指示第一阈值。
本发明实施例提供一种通信方法，所述方法包括：卫星确定寻呼时机；若所述寻呼时机位于第一时刻之前，所述卫星在所述寻呼时机发送唤醒信号；其中，所述第一时刻为第一时间间隔的结束时刻，所述第一时间间隔为用于为所述终端设备提供服务的卫星位于第一小区的覆盖范围内的时间间隔，所述第一小区为所述终端设备的服务小区。
可选的，若所述寻呼时机为所述第一时刻，所述卫星在所述寻呼时机不发送所述唤醒信号；或者，若所述寻呼时机位于所述第一时刻之后，所述卫星在所述寻呼时机不发送所述唤醒信号。
可选的，所述第一时刻与所述寻呼时机之间的间隔大于或等于第 一阈值。
可选的，若所述第一时刻与所述寻呼时机之间的间隔小于第一阈值，所述卫星在所述寻呼时机不发送所述唤醒信号。
可选的，所述卫星接收第一指示信息，所述第一指示信息用于指示第一阈值。
本发明实施例提供一种通信装置，所述装置包括：第一寻呼时机确定模块，用于确定寻呼时机；第一监听模块，用于当所述寻呼时机位于第一时刻之前时，在所述寻呼时机监听唤醒信号；其中，所述第一时刻为第一时间间隔的结束时刻，所述第一时间间隔为用于为所述通信装置提供服务的卫星位于第一小区的覆盖范围内的时间间隔，所述第一小区为所述通信装置的服务小区。
本发明实施例提供一种通信装置，所述装置包括：第二寻呼时机确定模块，用于确定寻呼时机；第二监听模块，用于当所述寻呼时机位于第一时刻之前时，在所述寻呼时机发送唤醒信号；其中，所述第一时刻为第一时间间隔的结束时刻，所述第一时间间隔为用于为终端设备提供服务的通信装置位于第一小区的覆盖范围内的时间间隔，所述第一小区为所述终端设备的服务小区。
本发明实施例提供一种可读存储介质，其上存储有计算机程序，所述计算机程序被处理器运行时执行上述通信方法的步骤。
本发明实施例提供一种通信装置，包括存储器和处理器，所述存储器上存储有能够在所述处理器上运行的计算机程序，所述处理器运行所述计算机程序时，使得所述通信装置执行上述通信方法的步骤。
本发明实施例提供一种通信装置，包括存储器和处理器，所述存储器上存储有能够在所述处理器上运行的计算机程序，所述处理器运行所述计算机程序时，使得所述通信装置执行上述通信方法的步骤。
与现有技术相比，本发明实施例的技术方案具有以下有益效果：
在本发明实施例中，终端设备在寻呼时机位于第一时刻之前的情况下，在所述寻呼时机监听唤醒信号，可以仅在卫星覆盖终端设备所在的服务小区，即卫星位于终端设备的服务小区时，终端设备有机会监听到唤醒信号的情况下，对唤醒信号进行监听，从而有效降低耗能，节约资源。
进一步，若寻呼时机位于第一时刻之前，且第一时刻与所述寻呼时机之间的间隔大于或等于第一阈值时，终端设备才会在所述寻呼时机监听唤醒信号，可以仅在寻呼时机非常早，寻呼时机与第一时刻之间的时间差较大的情况下，监听唤醒信号，从而进一步降低耗能，节约资源。
进一步，若所述第一时刻与所述寻呼时机之间的间隔小于第一阈值，所述终端设备在所述寻呼时机不监听唤醒信号，这是考虑终端设备在监听到唤醒信号后，还需接收寻呼消息以及发起随机接入以接收下行数据，这个过程需要耗费一定的时间，即使寻呼时机在第一时刻之前，终端设备监听到唤醒信号，也可能由于卫星即将离开第一小区的覆盖范围，来不及接收下行数据。因此，针对由于时间间隔太短导致终端设备来不及完成数据接收的情况，可以使终端设备在寻呼时机不监听唤醒信号，进一步降低耗能，节约资源。
进一步，所述终端设备接收第一指示信息，所述第一指示信息用于指示第一阈值，可以使得终端设备从网络设备接收第一阈值的指示信息，从而更准确地判断该时间差，从而在判断是否监听唤醒信号的过程中，有效提高准确性，避免由于错误判断而遗漏本该完成的数据接收业务。

需要说明的是，在本申请实施例中，第一时刻也可以理解为卫星移出终端设备的服务小区的时刻。在本发明实施例中，终端设备确定寻呼时机，然后根据寻呼时机和第一时刻，判定是否在寻呼时机监听唤醒信号，从而使得终端设备可以仅在卫星覆盖终端设备所在的服务小区时，监听唤醒信号，有机会降低耗能，节约资源。
进一步地，在一些实施例中，终端设备可以通过下列方式获取第一时刻：
方式一：卫星可以通过广播消息，向终端设备指示第一时刻。在这种情况下，广播消息用于指示第一时刻。即终端设备在接收到广播消息后，根据广播消息，确定第一时刻。不但便于终端设备获取第一时刻，而且有助于提高终端设备获取第一时刻的准确性和可靠性。
在一些示例中，卫星可以周期性地向覆盖的服务小区内的终端设备发送用于指示第一时刻的广播消息。
上述仅为触发卫星通过广播消息向终端设备指示第一时刻的举例说明，并不构成对本申请实施例的限定，在本申请实施例中还可以通过其它方式触发卫星通过广播消息向终端设备指示第一时刻。例如，卫星也可以通过事件触发向终端设备发送用于指示第一时刻的广播消息。
示例的，通过广播消息向终端设备指示第一时刻的卫星，可以为位于终端设备的服务小区的覆盖范围内的卫星。
方式二：卫星可以通过星历信息(ephemeris information)，向终端设备指示第一时刻。在这种情况下，星历消息用于指示第一时刻。 即终端设备在接收到星历消息后，根据星历消息，确定第一时刻。有助于简化终端设备获取第一时刻的方式，而且有助于提高终端设备获取第一时刻的准确性和可靠性。
在一些示例中，终端设备可以从网络设备或卫星获取星历信息。
上述仅为卫星通过星历信息向终端设备指示第一时刻的举例说明，并不构成对本申请实施例的限定，在本申请实施例中还可以通过其它方式触发卫星通过星历信息向终端设备指示第一时刻。
需要指出的是，通过星历信息指示第一时刻的卫星，可以为位于服务小区的覆盖范围内的卫星，也可以为位于服务小区的覆盖范围外的卫星。此外，通过星历信息指示第一时刻的卫星可以为一个，也可以为多个，本申请实施例对此不做限定。
下面结合具体示例，对终端设备根据第一时刻和寻呼时机，判定是否在寻呼时机监听唤醒信号的具体实现方式进行详细介绍。
示例一：
如图4所示，为本申请实施例的第二种通信方法的流程示意图，具体包括以下步骤：
步骤S41，终端设备确定寻呼时机。
具体的，关于步骤S41可以参见图3中步骤S31的相关描述，此处不再赘述。
步骤S42，若寻呼时机位于第一时刻之前，终端设备在寻呼时机监听唤醒信号。
关于第一时刻可以参见图3中的相关描述，在此不再赘述。
例如，如图5所示，T1为卫星1位于终端设备的服务小区的覆盖范围内的时间间隔，T2为卫星2位于终端设备的服务小区的覆盖范围内的时间间隔。时刻t11为时间间隔T1的起始时刻，时刻t12为时间间隔T1的结束时刻。时刻t21为时间间隔T2的起始时刻，时 刻t22为时间间隔T2的结束时刻。
其中，时刻t0为寻呼时机，其中，时刻t0位于时刻t12之前，则终端设备在时刻t0即寻呼时机，监听唤醒信号。
在本发明实施例中，由于在寻呼时机位于第一时刻之前，终端设备在寻呼时机监听唤醒信号的情况下，终端设备对唤醒信号进行监听，有助于提高终端设备监听到唤醒信号的可能性，降低因位于终端设备的服务小区的覆盖范围外，导致无法监听到唤醒信号的可能性，从而有效降低耗能，节约资源。
示例二：
如图6所示，为本申请实施例的第三种通信方法的流程示意图，具体包括以下步骤：
步骤S61，终端设备确定寻呼时机。
具体的，关于步骤S61可以参见图3中步骤S31的相关描述，此处不再赘述。
步骤S62，若寻呼时机为第一时刻，终端设备在寻呼时机不监听唤醒信号。
关于第一时刻可以参见图3中的相关描述，在此不再赘述。
例如，如图7所示，T1为卫星1位于终端设备的服务小区的覆盖范围内的时间间隔，T2为卫星2位于终端设备的服务小区的覆盖范围内的时间间隔。时刻t11为时间间隔T1的起始时刻，时刻t12为时间间隔T1的结束时刻。时刻t21为时间间隔T2的起始时刻，时刻t22为时间间隔T2的结束时刻。
其中，时刻t0为寻呼时机，其中，时刻t0与时刻t12重合，即寻呼时机为时刻t12，则终端设备在时刻t12即寻呼时机，不监听唤醒信号。
在本发明实施例中在寻呼时机为第一时刻的情况下，终端设备在 所述寻呼时机不监听唤醒信号，从而可以在寻呼时机与卫星移开覆盖服务小区时刻一致的情况下，降低耗能，节约资源。
示例三：
如图8所示，为本申请实施例的第四种通信方法的流程示意图，具体包括以下步骤：
步骤S81，终端设备确定寻呼时机。
具体的，关于步骤S81可以参见图3中步骤S31的相关描述，此处不再赘述。
步骤S82，若寻呼时机位于第一时刻之后，终端设备在寻呼时机不监听唤醒信号。
关于第一时刻可以参见图3中的相关描述，在此不再赘述。
例如，如图9所示，T1为卫星1位于终端设备的服务小区的覆盖范围内的时间间隔，T2为卫星2位于终端设备的服务小区的覆盖范围内的时间间隔。时刻t11为时间间隔T1的起始时刻，时刻t12为时间间隔T1的结束时刻。时刻t21为时间间隔T2的起始时刻，时刻t22为时间间隔T2的结束时刻。
其中，时刻t0为寻呼时机，其中，时刻t0位于时刻t12之后，即寻呼时机位于时刻t12之后，则终端设备在时刻t12即寻呼时机，不监听唤醒信号。
在本发明实施例中，由于在寻呼时机位于所述第一时刻之后的情况下，终端设备在寻呼时机不监听唤醒信号，从而可以在寻呼时机晚于卫星移开覆盖服务小区时刻的情况，降低终端设备的耗能，节约资源。
示例四：
如图10所示，为本申请实施例的第五种通信方法的流程示意图，具体包括以下步骤：
步骤S1001，终端设备确定寻呼时机。
具体的，关于步骤S1001可以参见图3中步骤S31的相关描述，此处不再赘述。
步骤S1002，若寻呼时机位于第一时刻之前、寻呼时机与第一时刻之间的时间间隔大于或等于第一阈值，终端设备在寻呼时机监听唤醒信号。
关于第一时刻可以参见图3中的相关描述，在此不再赘述。
例如，如图11所示，T1为卫星1位于终端设备的服务小区的覆盖范围内的时间间隔，T2为卫星2位于终端设备的服务小区的覆盖范围内的时间间隔。时刻t11为时间间隔T1的起始时刻，时刻t12为时间间隔T1的结束时刻。时刻t21为时间间隔T2的起始时刻，时刻t22为时间间隔T2的结束时刻。
其中，时刻t0为寻呼时机，Δt0为时刻t0与时刻t12之间的时间间隔，Δt1为第一阈值。时刻t0位于时刻t12之前，Δt0大于Δt1，即寻呼时机位于时刻t12之前，且寻呼时机与时刻t12之间的时间间隔大于第一阈值，终端设备在时刻t12即寻呼时机，监听唤醒信号。
在本发明实施例中，寻呼时机位于第一时刻之前，且第一时刻与所述寻呼时机之间的间隔大于或等于第一阈值时，终端设备才会在所述寻呼时机监听唤醒信号，可以仅在寻呼时机非常早，寻呼时机与第一时刻之间的时间差较大的情况下，监听唤醒信号，从而进一步降低耗能，节约资源。
进一步地，在一些实施例中，第一阈值是由网络设备指示给终端设备的。例如，网络设备向终端设备发送第一指示信息，第一指示信息用于指示第一阈值。终端设备接收到第一指示信息，获取第一阈值。有助于简化终端设备获取第一阈值的方式，而且，便于终端设备更准确地判断该时间差，并在判断是否监听唤醒信号的过程中，有效提高准确性，避免由于错误判断而遗漏本该完成的数据接收业务。
具体地，第一指示信息的发送方式可以选自：广播、组播以及单播。
在本发明实施例中，对于第一指示信息的具体发送方式可以不作限制。
具体地，网络设备可以通过专用信令发送该第一指示信息，或通过系统消息广播发送该第一指示信息。
在本发明实施例中，对于网络设备发送第一指示信息所使用的信令，不作限制。
或者，第一阈值也可以是终端设备根据某一策略或规则确定的，也可以是通过协议预定义的等，本申请实施例对终端设备获取第一阈值的方式不做限定。
示例五：
如图12所示，为本申请实施例的第六种通信方法的流程示意图，具体包括以下步骤：
步骤S1201，终端设备确定寻呼时机。
具体的，关于步骤S1201可以参见图3中步骤S31的相关描述，此处不再赘述。
步骤S1202，若寻呼时机位于第一时刻之前、寻呼时机与第一时刻之间的时间间隔小于第二阈值，终端设备在寻呼时机不监听唤醒信号。
关于第一时刻可以参见图3中的相关描述，在此不再赘述。
例如，如图13所示，T1为卫星1位于终端设备的服务小区的覆盖范围内的时间间隔，T2为卫星2位于终端设备的服务小区的覆盖范围内的时间间隔。时刻t11为时间间隔T1的起始时刻，时刻t12为时间间隔T1的结束时刻。时刻t21为时间间隔T2的起始时刻，时刻t22为时间间隔T2的结束时刻。
其中，时刻t0为寻呼时机，Δt0为时刻t0与时刻t12之间的时间间隔，Δt2为第二阈值。时刻t0位于时刻t12之前，Δt0小于Δt2，即寻呼时机位于时刻t12之前，且寻呼时机与时刻t12之间的时间间隔小于第二阈值，终端设备在时刻t12即寻呼时机，不监听唤醒信号。
在本发明实施例中，由于在第一时刻与寻呼时机之间的间隔小于第一阈值，终端设备所述寻呼时机不监听唤醒信号，从而有助于终端设备可以降低在第一时刻与寻呼时机之间的时间间隔太短，导致来不及完成数据接收的可能性，终端设备在寻呼时机不监听唤醒信号，进一步降低耗能，节约资源。
需要说明的是，在本申请实施例中，示例四中的第一阈值和示例五中的第二阈值可以为同一阈值，也可以为不同的阈值。在第一阈值与第二阈值为同一阈值的情况下，终端设备获取第二阈值的方式可以参见示例四中的相关介绍，在此不再赘述。
在第一阈值与第二阈值为不同阈值、且由网络设备指示给终端设备的情况下，网络设备可以通过同一信令或消息指示第一阈值和第二阈值，也可以通过不同的信令或消息分别指示第一阈值和第二阈值。
当然，第二阈值也可以是通过协议预定义的，或者由终端设备基于某一策略或规则确定的等，对此不做限定。还需要说明的是，终端设备获取第一阈值和第二阈值的方式也可以不同。例如，第一阈值是由网络设备指示的，第二阈值是通过协议预定义的。
此外，在一些实施例中，终端设备在监听到唤醒信号后，还需接收寻呼消息以及发起随机接入以接收下行数据，这个过程需要耗费一定的时间，即使寻呼时机在第一时刻之前，终端设备监听到唤醒信号，也会来不及接收寻呼消息，此时就没有必要使终端设备监听唤醒信号。
以分组唤醒信号包括三种唤醒信号(Wake Up Signal，WUS)的通信场景为例。如图14所示，分组唤醒信号可以包括WUS1、WUS2 和WUS3。其中，PO为寻呼时机，T1为接收WUS1的时刻与PO之间的时间间隔，即DRX偏移时长，T2为接收WUS2的时刻与寻呼时PO机之间的时间间隔，即为短扩展DRX(eDRX)偏移时长，T3为接收WUS3的时刻与寻呼时机之间的时间间隔，即长DRX偏移时长。
以上各个示例可以单独使用，也可以相互结合使用，以达到不同的效果。
如图15所示，为本发明实施例的第七通信方法的流程示意图，具体包括以下步骤：
步骤S1501：卫星确定寻呼时机；
在一些实施例中，卫星可以基于下列方式确定寻呼时机：
卫星根据寻呼消息配置信息，确定寻呼时机。其中，寻呼消息配置信息是由网络设备发送给卫星的。
其中，卫星可以根据寻呼消息配置信息中的寻呼周期、单个寻呼周期内的寻呼时机的个数，以及终端标识，确定寻呼时机。其中，终端标识可以是由网络设备发送给卫星的。具体确定方式可以依照现有的常规方法，本发明实施例对此不作限制。需要指出的是，在本申请实施例中，卫星还可以基于其他适当的方式确定寻呼时机，在此不做具体限制。
步骤S1502：卫星根据寻呼时机和第一时刻，判定是否在寻呼时机发送唤醒信号。
其中，第一时刻为第一时间间隔的结束时刻，第一时间间隔为用于为终端设备提供服务的卫星位于第一小区的覆盖范围内的时间间隔，第一小区为所述终端设备的服务小区。
需要说明的是，在本申请实施例中，第一时刻也可以理解为卫星移出终端设备的服务小区的时刻。在本发明实施例中，卫星确定寻呼 时机，然后根据寻呼时机和第一时刻，判定是否在寻呼时机发送唤醒信号，从而使得卫星可以仅在覆盖终端设备所在的服务小区时，发送唤醒信号，有机会使卫星降低耗能，节约资源。
进一步地，本发明实施例的通信方法还包括：所述卫星接收第一指示信息，所述第一指示信息用于指示第一阈值。
进一步地，在一些实施例中，卫星可以通过下列方式获取第一时刻：
方式一：卫星可以从网络设备获取第一时刻。
其中，所述第一时刻可以是网络设备根据运行距离、运行速度，先确定卫星位于第一小区的覆盖范围内的时间间隔，然后根据卫星位于第一小区的覆盖范围内的起始时刻，确定第一时间间隔的结束时刻，也即为第一时刻。
在一些示例中，还可以是由卫星根据运行距离、运行速度，确定卫星位于第一小区的覆盖范围内的时间间隔以及第一时刻的。
方式二：卫星可以通过星历信息(ephemeris information)确定第一时刻。有助于简化卫星确定第一时刻的方式，而且有助于提高卫星确定第一时刻的准确性和可靠性。
在一些示例中，卫星可以从网络设备获取星历信息。
上述仅为卫星获取第一时刻的举例说明，并不构成对本申请实施例的限定，在本申请实施例中卫星还可以通过其它方式确定第一时刻。
