为了更好地描述本公开任一实施例，本公开一实施例以一个接入控制的应用场景为例进行示例性说明。
请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，终端)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线终端。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12 采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
新一代的AR(Augmented Reality，增强现实)、VR(Virtual Reality，虚拟现实)以及车车通信等新型互联网应用的不断涌现对于无线通信技术提出了更高的要求，驱使无线通信技术的不断演进以满足应用的需求。当下，蜂窝移动通信技术正在处于新一代技术的演进阶段。新一代技术的一个重要特点就是要支持多种业务类型的灵活配置。由于不同的业务类型对于无线通信技术有不同的要求，如eMBB(Enhanced Mobile Broadband，增强移动宽带)业务类型主要的要求侧重在大带宽，高速率等方面；URLLC(Ultra-reliable and Low Latency Communications，高可靠和低延迟通信)业务类型主要的要求侧重在较高的可靠性以及低的时延方面；mMTC(Massive MachineType Communication，大规模机器类型通信)业务类型主要的要求侧重在大的连接数方面。因此新一代的无线通信系统需要灵活和可配置的设计来支持多种业务类型的传输。
在无线通信技术中，卫星通信是未来无线通信技术发展的一个重要方面。卫星通信是指地面上的无线电通信设备利用卫星作为中继而进行的通信。卫星通信系统由卫星部分和地面部分组成。卫星通信的特点是：通信范围大；只要在卫星发射的电波所覆盖的范围内，从任何两点之间都可进行通信；不易受陆地灾害的影响(可靠性高)。卫星通信作为目前地面的蜂窝通信系统的补充，可以有以下的好处：
第一、延伸覆盖：对于目前蜂窝通信系统无法覆盖或是覆盖成本较高的地区，如海洋，沙漠，偏远山区等，可以通过卫星通信来解决通信的问题。
第二、应急通信：在发生灾难如地震等的极端情况下导致蜂窝通信的基础设施不可用的条件下，使用卫星通信可以快速的建立通信连接。
第三、提供行业应用：比如对于长距离传输的时延敏感业务，可以通过卫星通信的方式来降低业务传输的时延。
可以预见，在未来的无线通信系统中，卫星通信系统和陆地上的蜂窝通信系统会逐步的实现深度的融合，真正的实现万物智联。
基于上述卫星通信系统与陆地通信系统的融合，如图2所示，本公开实施例提供一种通信方法，该方法应用于终端中，包括：
步骤S101、根据配置信息，确定终端进入省电状态；其中，所述配置信息基于所述终端的服务卫星的覆盖状态确定。
在本公开实施例中，终端可以基于服务卫星的覆盖状态所确定的配置信息来切换不同的状态。终端的省电状态为：根据服务卫星的覆盖状态确定终端在激活状态与休眠状态之间切换方式的状态。相比于不考虑卫星覆盖的周期性激活等模式，省电状态可以是非周期性的激活，例如，在服务卫星覆盖的情况下，终端进入的激活状态，而在服务卫星未覆盖的范围内则不进行PDCCH监听等通信活动，即保持处于休眠状态，休眠态包括空闲态和非激活态。又如，在服务卫星覆盖的范围下，终端进入周期性监听的状态，而在服务卫星未覆盖的范围内则始终处于休眠状态，不进行周期性状态切换。
在一些实施例中，终端采用周期性地DRX配置的方式，通过周期性地进入激活状态监听PDCCH，来达到节省功耗的目的。但是这种方式并未考虑到卫星覆盖的特点，当终端处于服务卫星的覆盖范围以外时，仍然周期性地激活并监听PDCCH，但实际上却无法接收到下行信息，从而造成了功耗的浪费。
因此，在本公开实施例中，终端基于将服务卫星覆盖的特点实现状态切换，也就是基于服务卫星覆盖状态确定的配置信息来进入终端的省电状态。如此，一方面不影响终端在服务卫星覆盖范围内的正常通信，另一方面，在服务卫星覆盖范围以外可以减少功耗的浪费，达到省电的目的。
在一些实施例中，所述配置信息由协议约定或者由基站下发。
在本公开实施例中，终端可以通过协议的约定确定上述配置信息，也可通过基站来获取上述配置信息。例如，基站获取服务卫星的覆盖状态相关的信息，终端则可接收基站基于服务卫星状态确定的配置信息。
此外，终端也可通过协议所预定的方式来获取上述配置信息，例如，协议约定接收上述配置信息，在终端根据协议中约定的配置信息确定自身的监听状态等等。又如，根据协议，终端自身可在获取到服务卫星的星历信息等信息时，根据星历信息确定上述配置信息。例如，根据星历信息确定终端进入省电状态的时间等。
在一些实施例中，所述配置信息由基站下发，所述方法包括：
接收基站下发的携带有所述配置信息的信令，其中，所述信令包括以下至少之一：
RRC信令；MAC信令；物理层信令。
终端可以通过与基站随机接入过程中的各层不同信令接收上述配置信息。例如，在上述信令中的加入上述配置信息所对应的字段或者字符位等，也可通过隐式的方式，例如，编解码方式、校验方法等标识上述配置信息。
如此，在终端与基站的随机接入等过程中，就可以获取到基站下发的配置信息，并进一步确定自身进入上述省电状态的具体信息。
当然，终端也可通过专用的信令获取上述配置信息，或者从基站广播中获取上述配置信息。
在一些实施例中，所述配置信息，包括以下至少之一：
用于确定所述终端进入所述省电状态的时间信息；
指示所述终端进入所述省电状态的指示信息。
在本公开实施例中，终端可根据上述配置信息确定进入省电状态的 时间信息，例如，进入省电状态的起始时间、终止时间或者时长等等。终端则可根据上述时间信息确定何时进入省电状态以及结束省电状态。
此外，上述配置信息也可以为指示终端进入省电状态的指示信息，也就是说，终端可以在接收到配置信息后按照指示信息进入省电状态，并根据配置信息确定在省电状态中的激活或者休眠的切换方式以及切换周期等。
需要说明的是，这里终端进入省电状态并不代表终端进入了休眠状态，而是采取了相比于原有的周期性激活的方式更为省电的方式。
示例性地，省电状态下，在服务卫星的覆盖范围内，终端可根据预定的第一周期切换激活状态与休眠状态，而在服务卫星的覆盖范围以外，则以预定的第二周期切换激活状态与休眠状态。并且在覆盖范围以外的情况下，每个周期内激活状态的时长相比于覆盖范围内每个周期激活状态的时长更短。而在非省电状态下，终端则可根据DRX配置的周期、时长等进行激活状态与休眠状态的切换。
又如，省电状态下，若终端处于服务卫星的覆盖范围以外，则进入休眠状态，若处于服务卫星覆盖范围以内，则以DRX配置的周期、时长等进行状态切换。
在一些实施例中，所述时间信息，包括：
根据所述服务卫星的星历信息确定的终端进入所述省电状态的时间信息。
上述时间信息可以为用于确定所述终端进入所述省电状态的时间信息，例如，根据服务卫星的星历信息，确定终端在指定的时长之后进入省电状态、进入省电状态后维持在省电状态的时长或者进入省电状态后，切换激活状态与休眠状态的时间、周期等信息。
上述时间信息可以为绝对的时间，例如，进入省电状态1个小时、 20分钟后进入省电状态等等。也可以为逻辑时间，例如，进入省电状态持续1000个子帧等，此时，时间信息还可包括上述逻辑时间的参照时长信息，例如，逻辑时间为10个时隙(slot)。跟据时隙对应的参数集(numerology)信息，可以确定每个时隙对应的绝对时长，如参数频率为15kHz，那么每个时隙的时长为1ms(毫秒)。
在一些实施例中，所述省电状态，包括：DRX配置的激活状态和休眠状态；所述指示信息，包括以下至少之一：
指示终端进入激活状态或者所述休眠状态的起始时刻和持续时长；
指示终端进入激活状态或者所述休眠状态的起始时刻和结束时刻；
指示终端进入激活状态或者所述休眠状态后进行下行信息检测的检测信息；
指示终端的至少一个服务时段内的服务卫星的卫星信息。
在本公开实施例中，省电状态至少包括DRX配置的激活状态与休眠状态。因此，上述指示信息可以包括对终端切换激活状态与休眠状态相关的时间信息等。
在本公开实施例中，终端接收到上述指示信息后，可进入省电状态，并根据指示信息中所包含的进入激活状态或者休眠状态的起始时刻以及持续时长或者结束时刻等信息，进行激活状态与休眠状态的切换。
在本公开实施例中，上述指示信息还可包括针对终端进入激活状态或者进入休眠状态后的行为，例如，终端进入休眠状态后，仍然会对下行信息进行一些检测，比如物理层下行信号或者下行信令等等。因此，上述指示信息还可以用于指示终端进行这些信号或者信令检测的时间、周期、检测次数以及检测方式等检测信息。
此外，上述指示信息还可包括：指示终端在后续时段内的服务卫星的相关信息，例如，下一服务卫星的卫星信息。如此，便于终端根据指 示信息确定后续进入省电状态的情况。
在一些实施例中，所述检测信息，包括以下至少之一：
检测方式；
检测次数；
标识信息。
这里，终端进入激活状态或者休眠状态后，可根据上述检测信息确定自身的检测行为。包括上述检测方式，例如根据指示信息终端在省电状态下需要对于PDCCH进行检测，那么所述检测方式包括PDCCH上承载的下行控制信息的聚合度等级；检测次数以及下行控制信息的类型等。
在一些实施例中，所述方法还包括：
响应于所述终端基于所述指示信息进入所述休眠状态，根据所述检测信息进行检测。
在本公开实施例中，终端基于指示信息进入休眠状态后，可以检测信息确定终端进入休眠状态后的行为。
示例性地，终端进入休眠状态后，不执行任何上行数据的传输，同时，可基于上述检测信息所确定的检测方式、检测次数以及标识信息等，进行周期性检测GNSS(Global Navigation Satellite System，全球导航卫星系统)信息、定位信息或者其他需要检测的信息等。
另外，终端还可基于配置信息确定何时切换到激活状态，以及在切换到激活状态时快速系统接入的相关信息，例如，快速接入所需的随机接入前导码(Preamble序列)以及时频资源等信息。
如图3所示，本公开实施例提供一种通信方法，该方法应用于基站中，包括：
步骤S201、下发用于确定终端进入省电状态的配置信息；其中，所述配置信息基于终端的服务卫星的覆盖状态确定。
在本公开实施例中，终端的省电状态为根据服务卫星的覆盖状态进行终端状态切换的模式。相比于不考虑卫星覆盖的周期性激活等模式，省电状态可以是非周期性的激活，例如，在服务卫星覆盖的情况下，终端进入的激活状态，而在服务卫星未覆盖的范围内则不进行PDCCH监听等通信活动，即保持处于休眠状态。又如，在服务卫星覆盖的范围下，终端进入周期性监听的状态，而在服务卫星未覆盖的范围内则始终处于休眠状态，不进行周期性状态切换。
在一实施例中，基站可根据协议约定，相机站下发上述配置信息，例如，当终端处于连接态时，基站向终端下发上述配置信息；在终端处于空闲态或者非激活态时，基站则通过广播的方式下发上述配置信息等。
在本公开实施例中，基站根据终端的服务卫星的覆盖状态确定上述配置信息，便于终端基于将服务卫星覆盖的特点实现状态切换，也就是基于服务卫星覆盖状态确定的配置信息来进入终端的省电状态。如此，一方面不影响终端在服务卫星覆盖范围内的正常通信，另一方面，在服务卫星覆盖范围以外可以减少功耗的浪费，达到省电的目的。
在一些实施例中，所述下发用于确定终端进入省电状态的配置信息，包括：
下发携带有所述配置信息的信令；其中，所述信令包括以下至少之一：
RRC信令；MAC信令；物理层信令。
基站可以在终端随机接入过程中的各层不同信令携带上述配置信息。例如，在上述信令中的加入上述配置信息所对应的字段或者字符位等，也可通过隐式的方式，例如，编解码方式、校验方法等标识上述配置信息。
如此，在终端随机接入等过程中，基站就可以将根据服务卫星覆盖 状况确定的配置信息下发至终端，便于终端确定进入省电状态。
当然，基站也可通过专用的信令下发上述配置信息。
在一些实施例中，所述配置信息，包括以下至少之一：
用于确定所述终端进入所述省电状态的时间信息；
指示所述终端进入所述省电状态的指示信息。
在本公开实施例中，上述配置信息可用于供终端确定进入省电状态的时间信息，例如，进入省电状态的起始时间、终止时间或者时长等等。终端则可根据上述时间信息确定如何进行
此外，上述配置信息也可以为指示终端进入省电状态的指示信息，也就是说，终端可以在接收到配置信息后进入省电状态，并根据配置信息确定在省电状态中的激活或者休眠的切换方式以及切换周期等。
需要说明的是，这里终端进入省电状态并不代表终端进入了休眠状态，而是采取了相比于原有的周期性激活的方式更为省电的方式。
示例性地，省电状态下，在服务卫星的覆盖范围内，终端可根据预定的第一周期切换激活状态与休眠状态，而在服务卫星的覆盖范围以外，则以预定的第二周期切换激活状态与休眠状态。并且在覆盖范围以外的情况下，每个周期内激活状态的时长相比于覆盖范围内每个周期激活状态的时长更短。而在非省电状态下，终端则可根据DRX配置的周期、时长等进行激活状态与休眠状态的切换。
又如，省电状态下，若终端处于服务卫星的覆盖范围以外，则进入休眠状态，若处于服务卫星覆盖范围以内，则以DRX配置的周期、时长等进行状态切换。
在一些实施例中，所述时间信息，包括：
根据所述服务卫星的星历信息确定的终端进入所述省电状态的时间信息。
上述时间信息可以为用于确定所述终端进入所述省电状态的时间信息，例如，根据服务卫星的星历信息，确定终端在指定的时长之后进入省电状态、进入省电状态后维持在省电状态的时长或者进入省电状态后，切换激活状态与休眠状态的时间、周期等信息。
上述时间信息可以为绝对的时间，例如，进入省电状态1个小时、20分钟后进入省电状态等等。也可以为逻辑时间，例如，进入省电状态持续1000个子帧等，此时，时间信息还可包括上述逻辑时间的参照时长信息，例如，逻辑时间为10个时隙(slot)。根据时隙对应的参数集(numerology)信息，可以确定每个时隙对应的绝对时长，如参数频率为15kHz，那么每个时隙的时长为1ms。
在一些实施例中，所述省电状态，包括：DRX配置的激活状态和休眠状态；所述指示信息，包括以下至少之一：
指示终端进入激活状态或者所述休眠状态的起始时刻和持续时长；
指示终端进入激活状态或者所述休眠状态的起始时刻和结束时刻；
指示终端进入激活状态或者所述休眠状态后进行物理层下行信息检测的检测信息；
指示终端的至少一个服务时段内的服务卫星的卫星信息。
在本公开实施例中，省电状态至少包括DRX配置的激活状态与休眠状态。因此，上述指示信息可以包括对终端切换激活状态与休眠状态相关的时间信息等。
在本公开实施例中，基站下发上述指示信息到终端后，终端可进入省电状态，并根据指示信息中所包含的进入激活状态或者休眠状态的起始时刻以及持续时长或者结束时刻等信息，进行激活状态与休眠状态的切换。
在本公开实施例中，上述指示信息还可包括针对终端进入激活状态 或者进入休眠状态后的行为，例如，指示终端进入休眠状态后，对下行信息进行一些检测，比如物理层下行信号或者下行信令等等。因此，上述指示信息还可以用于指示终端进行这些信号或者信令检测的时间、周期、检测次数以及检测方式等检测信息。
在一些实施例中，所述检测信息，包括以下至少之一：
检测方式；
检测次数；
标识信息。
这里，终端进入激活状态或者休眠状态后，可根据上述检测信息确定自身的检测行为。根据指示信息终端在省电状态下需要对于PDCCH进行检测，那么所述检测方式包括PDCCH上承载的下行控制信息的聚合度等级；检测次数以及下行控制信息的类型等。
本公开实施例还提供如下示例：
在一些实施例中，终端在处于休眠态的时候，终端需要基于基站的配置，周期性地监听PDCCH，以确定是否需要进入激活状态。为了监听PDCCH，终端需要持续监听一段时间，这会使得终端消耗一定的能量，如图4所示。
对于卫星通信，在低轨卫星部署的初期，受限于卫星数量，无法做到全天候的覆盖。在这种情况下，终端可能只在有卫星覆盖的情况下才能够进行数据交互。在其他时间，终端没有必要去进行下行信号或者信令的接收，以及上行信号或者信令的发送。因此，上述周期性监听PDCCH的方式，即周期性配置DRX的方式会造成更多的功耗浪费。
因此，在本公开实施例中，提供了一种可应用于卫星通信系统的终端省电的方法，从而使得终端在没有服务卫星提供覆盖的情况下，减少无效的操作，从而节省终端功耗，达到省电的目的。
在本公开实施例中，终端基于服务卫星的存在情况确定进入到休眠状态：
方式1：基于星历信息；
终端基于星历信息确定进入到休眠状态的时间信息。所述时间信息可以是一个绝对的时间，比如1个小时等；也可以是一个逻辑的时间，比如1000个子帧等。当所述时间信息是一个逻辑的时间时，还需要逻辑时间的参照时长信息，比如当所述时间信息是10个时隙，还需要所述时隙上对应的参数集的信息，例如当参数集指示的频率是15KHz时，一个时隙的时间长度就是1毫秒。
终端可以通过预先定义的方法或是获取基站通过卫星发给终端的配置信息来获取的。所述配置信息通过高层信令如RRC信令，MAC信令或是物理层信令通知给终端。
方式2：基于触发终端进入省电状态的指示信息，也就是触发信令；
在这种方式下，终端基于基站发送的触发指令进入到休眠状态或激活状态。触发指令可以是高层信令或是物理层信令。在信令中可以包含以下信息：
指示终端需要进入休眠状态或激活状态的起始时间，时间长度或是结束时间；
指示终端在进入到激活状态或进入到休眠状态后的终端的检测行为的检测信息。
指示终端下一个服务时间内提供服务的服务卫星的相关信息。
所述用于指示进入到休眠状态或是激活状态的信令可以是相同的信令或是不同的信令。终端可以基于预先定义的方法或是接收基站的配置信息确定接收所述触发信令的方法，包括时间信息，检测方式如聚合度等级，检测次数，RNTI(RNTI Radio Network Tempory Identity，无线网 络临时标识)等。
当终端进入到休眠状态后，终端基于预先定义的方法或是触发信令通知的方式确定终端在进入到休眠态的行为。
在一种实施方法下，终端在进入到休眠态之后，不执行任何上行数据的传输。同时终端基于配置信息，还需要周期性的检测GNSS信息或是其他需要检测的信息。另外，终端还可以经由配置信息确定当切换到激活状态时，终端需要进行快速的系统接入。所述用于快速接入系统的相关配置信息如随机接入前导码以及时频资源等信息。
