具体实施方式
现有技术中，终端设备在寻呼时机到来时，需要唤醒以接收寻呼消息。然而，终端设备上一次接收的广播SIB32/SIB32-NB消息会在一段时间内保持有效性，如果终端设备在该段时间内每个覆盖时段都重新获取SIB32/SIB32-NB消息，会导致终端设备不必要的功耗开销。另外，在一些覆盖时段内并没有终端设备对应的寻呼时机，导致终端设备无法正常接收寻呼消息，造成终端设备的不必要的功耗开销；或者终端设备唤醒时，终端设备对应的服务小区无卫星覆盖，导致终端设备无法正常接收寻呼消息，同样造成终端设备的不必要的功耗开销。
在本发明实施例中，终端设备根据第一系统消息，获知当前覆盖时间段之后的N个进入当前小区的卫星对应的覆盖时间段。由此，终端设备能够知道后续的N个覆盖时间段，进而仅在覆盖时间段内唤醒来接收寻呼消息，从而可以有效降低功耗。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。

2、接入网设备。本发明实施例中，接入网设备是一种为终端提供无线通信功能的设备，也可称之为无线接入网(radio access network，RAN)设备、或接入网网元等。其中，接入网设备可以支持至少一种无线通信技术，例如LTE、NR等。示例的，接入网设备包括但不限于：第五代移动通信系统(5th-generation，5G)中的下一代基站(generation nodeB，gNB)、演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站接收台(base transceiver station，BTS)、家庭基站(例如，home evolved node B、或home node B，HNB)、基带单元(baseband unit，BBU)、接收点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心等。网络设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器、集中单元(centralized unit，CU)、和/或分布单元(distributed unit，DU)，或者接入网设备可以为中继站、接入点、车载设备、终端设备、可穿戴设备以及未来移动通信中的接入网设备或者未来演进的PLMN中的接入网设备等。在一些实施例中， 接入网设备还可以为具有为终端设备提供无线通信功能的装置，例如芯片系统。示例的，芯片系统可以包括芯片，还可以包括其它分立器件。
在一些实施例中，接入网设备还可以与互联网协议(Internet Protocol，IP)网络进行通信，例如因特网(internet)，私有的IP网，或其他数据网等。
本发明实施例提供了一种非连续覆盖的通信方法，参照图1，以下通过具体步骤进行详细说明。
在本发明实施例中，下述步骤101～步骤102对应的非连续覆盖的通信方法可以由终端设备中具有数据处理能力的芯片所执行，或者由终端设备中包括上述具有数据处理能力的芯片的芯片模组所执行。以下以终端设备为执行主体为例进行介绍。
步骤101，在当前覆盖时间段内，获取广播的第一系统消息。
在本发明实施例中，终端设备可以在当前覆盖时间段内，获取接入网设备广播的第一系统消息。
在具体实施中，接入网设备广播的第一系统消息可以为SIB32消息，或者SIB32-NB消息。终端设备可以在当前覆盖时间段内，获取接入网设备广播的第一系统消息。第一系统消息可以包括：当前覆盖时间段之后的N个进入当前小区的卫星对应的覆盖时间段，N≥1。当前小区可以为终端设备当前驻留的服务小区。
在具体实施中，第一系统消息还可以包括下一次覆盖当前小区的卫星星历信息。
在本发明实施例中，上述的进入当前小区的卫星对应的覆盖时间段可以包括：卫星进入当前小区的时刻信息；卫星离开当前小区的时刻信息，或者卫星在当前小区的停留时长。
在具体实施中，进入当前小区的卫星对应的覆盖时间段可以为： 在当前覆盖时间段之后的预设时长内，进入当前小区的卫星对应的覆盖时间段。
也就是说，终端设备可以在进入当前小区的卫星对应的覆盖时间段内重新唤醒。换言之，终端设备仅在当前小区被卫星覆盖的覆盖时间段唤醒。若当前小区未被卫星覆盖，则终端设备无需唤醒，故而可以有效减少终端设备的功耗。
在具体实施中，预设时长的具体取值可以与具体应用场景相关。预设时长可以为10分钟，也可以为20分钟或者其他时长。
参照图2，给出了本发明实施例中的一种覆盖时间段的时序示意图。当前覆盖时间段T0与第一覆盖时间段T1之间、第一覆盖时间段T1与第二覆盖时间段T2之间、第二覆盖时间段T2与第三覆盖时间段T3之间、第三覆盖时间段T3与第四覆盖时间段T4之间均存在间隙(GAP)，间隙(GAP)意味着当前小区没有卫星覆盖。
当前覆盖时间段T0的起始时刻(也即卫星进入当前小区的时刻)为t0，当前覆盖时间段T0的结束时刻(也即卫星离开当前小区的时刻)为t1。第一覆盖时间段T1的起始时刻为t2，第二覆盖时间段T2的起始时刻为t3，第三覆盖时间段T3的起始时刻为t4，第四覆盖时间段T4的起始时刻为t5。
在当前覆盖时间段T0，接入网设备广播的第一系统消息包括：第一覆盖时间段T1、第二覆盖时间段T2、第三覆盖时间段T3以及第四覆盖时间段T4。在第一覆盖时间段T1、第二覆盖时间段T2、第三覆盖时间段T3以及第四覆盖时间段T4，均有卫星覆盖当前小区。需要说明的是，第一覆盖时间段T1、第二覆盖时间段T2、第三覆盖时间段T3以及第四覆盖时间段T4，经过当前小区的卫星可以为不同的卫星。
在当前覆盖时间段T0结束之后，在时间到达t2时刻时，t2时刻对应的覆盖时间段T1(t2～t2+△t，△t为卫星在当前小区的停留时长) 即为当前覆盖时间段。此时，接入网设备广播的第一系统消息包括：第二覆盖时间段T2、第三覆盖时间段T3、第四覆盖时间段T4以及第五覆盖时间段(图2中未示出)。第五覆盖时间段与第四覆盖时间段T4相邻且时序上位于第四覆盖时间段T4之后。
在时间达到t3时刻时，t3时刻对应的覆盖时间段T2(t3～t3+△t，△t为卫星在当前小区的停留时长)即为当前覆盖时间段。此时，接入网设备广播的第一系统消息包括的覆盖时间段如下：第三覆盖时间段T3、第四覆盖时间段T4、第五覆盖时间段以及第六覆盖时间段(图2中未示出)。第五六覆盖时间段与第五覆盖时间段相邻且时序上位于第五覆盖时间段之后。
以此类推，接入网设备每一次广播的第一系统消息中，均可以包括：预设时长内，当前覆盖时间段之后的N个进入当前小区的卫星对应的覆盖时间段。
可见，随着时间的推移，当前覆盖时间段对应的时刻也随之发生改变，相应地，第一系统消息包含的覆盖时间段也可以对应发生变化。
在本发明实施例中，进入当前小区的卫星对应的覆盖时间段也可以为：在预设时刻到达之前，当前覆盖时间段之后，N个进入当前小区的卫星对应的覆盖时间段。
继续以上述示例进行说明，预设时刻为t6。在当前覆盖时间段T0，接入网设备广播的第一系统消息包括的覆盖时间段如下：第一覆盖时间段T1、第二覆盖时间段T2、第三覆盖时间段T3以及第四覆盖时间段T4。
在当前覆盖时间段结束之后，在时间到达t2时刻时，t2时刻对应的覆盖时间段T1即为当前覆盖时间段。此时，接入网设备广播的第一系统消息包括的覆盖时间段如下：第二覆盖时间段T2、第三覆盖时间段T3以及第四覆盖时间段T4。
在时间达到t3时刻时，t3时刻对应的覆盖时间段T2即为当前覆 盖时间段。此时，接入网设备广播的第一系统消息包括的覆盖时间段如下：第三覆盖时间段T3以及第四覆盖时间段T4。
在时间达到t4时刻时，t4时刻对应的覆盖时间段T3即为当前覆盖时间段。此时，接入网设备广播的第一系统消息包括的覆盖时间段如下：第四覆盖时间段T4。
可见，随着时间的推移，当前覆盖时间段对应的时刻也随之发生改变。由于第一系统消息中承载的时刻均早于预设时刻，因此，当前覆盖时间段对应的时刻不同，第一系统消息包含的覆盖时间段也可以对应发生变化。
综上可见，由于终端设备能够知道当前覆盖时间段之后的N个覆盖时间段，进而仅在N个覆盖时间段内唤醒来接收寻呼消息，从而可以有效降低功耗。
在具体实施中，第一系统消息还可以包括第一系统消息对应的有效性时长。在第一系统消息的有效性时长范围之内，终端设备可以无需重新获取第一系统消息。
在本发明实施例中，在第一系统消息的有效性时长范围之内，终端设备可以无需重新获取第一系统消息，可以是指：在第一系统消息的有效性时长范围之内，终端设备可以唤醒，但是无需重新获取第一系统消息。
例如，在当前覆盖时间段T0内接入网设备广播的第一系统消息包括的覆盖时间段如下：第一覆盖时间段T1、第二覆盖时间段T2、第三覆盖时间段T3以及第四覆盖时间段T4。
第一系统消息对应的有效性时长为δ1，且t1+δ1在时序上晚于第二覆盖时间段T2的结束时刻且早于第三覆盖时间段T3的起始时刻。因此，在第一覆盖时间段T1以及第二覆盖时间段T2内，第一系统消息处于有效期内。在第三覆盖时间段T3内，第一系统消息处于有效期外。
由此，终端设备在第一覆盖时间段T1以及第二覆盖时间段T2内可以唤醒，但是无需重新获取第一系统消息，终端设备在第三覆盖时间段T3内，需要唤醒并重新获取第一系统消息。
在本发明实施例中，在第一系统消息的有效性时长范围之内，终端设备可以无需重新获取第一系统消息，也可以是指：
在第一系统消息的有效性时长范围之内，若无需监听寻呼消息，则终端设备无需唤醒，也无需重新获取第一系统消息。
例如，终端设备在第一覆盖时间段T1以及第二覆盖时间段T2无需监听寻呼消息，在第三覆盖时间段T3内需要监听寻呼消息。终端设备在第一覆盖时间段T1以及第二覆盖时间段T2，无需唤醒，从而可以进一步降低功耗。终端设备在第三覆盖时间段T3唤醒，监听寻呼消息并重新获取第一系统消息。
由此，通过设置第一系统消息的有效性时长，终端设备无需在每一次唤醒都重新获取第一系统消息，也即减少了不必要的第一系统消息的获取。
终端设备进在接收寻呼消息的覆盖时间段，唤醒并重新获取第一系统消息；在不接收寻呼消息的覆盖时间段，终端设备无需唤醒。由此，可以进一步降低终端设备的功耗。
在具体实施中，若在有效性时长内，存在多个寻呼时机关联的覆盖时间段，则终端设备可以最后一个寻呼时机关联的覆盖时间段内唤醒，监听寻呼消息并重新获取第一系统消息。
例如，第一系统消息对应的有效性时长为δ2，且t1+δ2在时序上晚于第三覆盖时间段T3的结束时刻且早于第四覆盖时间段T4的起始时刻。
终端设备在第一覆盖时间段T1、第二覆盖时间段T2以及第三覆盖时间段T3均需要接收寻呼消息。因此，终端设备在第一覆盖时间段T1、第二覆盖时间段T2以及第三覆盖时间段T3均需要唤醒。
终端设备在第一覆盖时间段T1、第二覆盖时间段T2无需重新获取第一系统消息，仅在第三覆盖时间段T3内重新获取第一系统消息。
可见，若第一系统消息的有效性时长内，根据接收寻呼消息的覆盖时间段，来确定是否重新获取第一系统消息，也可以进一步减少第一系统消息的获取次数。
步骤102，根据寻呼周期计算寻呼时机，根据寻呼时机以及第一系统消息，确定寻呼时机的覆盖时间段和/或重新获取第一系统消息的覆盖时间段。
在本发明实施例中，上述步骤102为可选的步骤。
在具体实施中，终端设备可以根据寻呼周期计算寻呼时机。终端设备计算寻呼时机的具体方法可以参照现有技术，本发明实施例不做赘述。
终端设备在计算得到寻呼时机之后，可以确定寻呼时机与上述N个覆盖时间段中的哪些存在关联。寻呼时机与覆盖时间段关联，可以是指：寻呼时机对应的时刻，位于该覆盖时间段范围之内。
例如，寻呼时机对应的时刻为t2’，t2’位于第一覆盖时间段T1范围之内，则确定寻呼时机与第一覆盖时间段T1关联。
在确定与寻呼时机关联的覆盖时间段之后，终端设备可以在关联的覆盖时间段唤醒，并接收寻呼消息。如上述实施例中所述，终端设备在接收寻呼消息的覆盖时间段，还可以重新获取第一系统消息。
因此，终端设备根据寻呼时机以及第一系统消息，可以确定寻呼时机的覆盖时间段，也可以确定重新获取第一系统消息的覆盖时间段(可以与寻呼时机的覆盖时间段相同)。
继续上述示例，确定寻呼时机与第一覆盖时间段T1关联，则终端设备可以在第一覆盖时间段T1内唤醒，并接收寻呼消息。
在本发明实施例中，接入网设备可以预先广播时间间隔的门限 值，上述的时间间隔可以为：寻呼时机与关联的覆盖时间段的起始时刻之间的时间间隔。若寻呼时机与某一覆盖时间段的起始时刻之间的时间间隔小于等于该时间间隔的门限值，则终端设备在该覆盖时间段唤醒并监听寻呼消息。
例如，接入网设备预先广播的时间间隔的门限值为δ。终端设备检测到寻呼时机与第二覆盖时间段T2的起始时刻t3之间的时间间隔小于δ，则终端设备在第二覆盖时间段T2内唤醒并监听寻呼消息。
在具体实施中，终端设备也可以根据寻呼周期计算寻呼传输窗起点。终端设备计算寻呼传输窗起点的具体方法可以参照现有技术，本发明实施例不做赘述。
终端设备在计算得到寻呼传输窗起点之后，可以确定寻呼传输窗起点与上述N个覆盖时间段中的哪些存在关联。寻呼传输窗起点与覆盖时间段关联，可以是指：寻呼传输窗起点对应的时刻，位于该覆盖时间段范围之内。
在确定与寻呼传输窗起点关联的覆盖时间段之后，终端设备可以在关联的覆盖时间段唤醒，并接收寻呼消息。
在本发明实施中，接入网设备可以预先广播时间间隔的门限值，上述的时间间隔也可以为：寻呼传输窗起点与关联的覆盖时间段的起始时刻之间的时间间隔。若寻呼传输窗起点与某一覆盖时间段的起始时刻之间的时间间隔小于等于该时间间隔的门限值，则终端设备在该覆盖时间段唤醒并监听寻呼消息。
由此可见，在寻呼时机或寻呼传输窗起点到来时，终端设备唤醒并重新获取第一系统消息，可以保证寻呼消息的准确监听。
参照图3，给出了本发明实施例中的另一种非连续覆盖的通信方法，以下通过具体步骤进行详细说明。

步骤301，在当前覆盖时间段内，广播发送第一系统消息。
在具体实施中，接入网设备广播的第一系统消息可以为SIB32消息，或者SIB32-NB消息。终端设备可以在当前覆盖时间段内，获取接入网设备广播的第一系统消息。第一系统消息可以包括：当前覆盖时间段之后的N个进入当前小区的卫星对应的覆盖时间段，N≥1。当前小区可以为终端设备当前驻留的服务小区。
在具体实施中，第一系统消息还可以包括下一次覆盖当前小区的卫星星历信息。
在本发明实施例中，上述的进入当前小区的卫星对应的覆盖时间段可以包括：卫星进入当前小区的时刻信息；卫星离开当前小区的时刻信息，或者卫星在当前小区的停留时长。
