Description

终端节能方法、装置及系统
本申请要求于2021年9月1日提交国家知识产权局、申请号为202111022590.4、发明名称为“终端节能方法、装置及系统”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
本申请涉及通信技术领域，尤其涉及终端节能方法、装置及系统。
背景技术
随着通信技术的发展，扩展现实(extended reality，XR)(例如虚拟现实(virtual reality，VR))业务也随之出现。为了提升用户体验，要求运行XR业务的终端设备轻量化(例如VR眼镜)，且要求运行XR业务的通信系统高吞吐低时延，为了实现这些要求，终端设备运行XR业务所需的功耗较高。因此，为了终端设备的正常运行，应该尽量降低终端设备的功耗。
目前，连接态下的非连续接收(connected discontinuous reception，CDRX)机制是一种有效的节能技术。配置CDRX机制的终端设备分为“唤醒状态”和“睡眠状态”，处于“唤醒状态”的终端设备可以监听物理下行控制信道(physical downlink control channel，PDCCH)来传输业务数据。终端设备保持“唤醒状态”一定时间后，进入“睡眠状态”，处于“睡眠状态”的终端设备不监听PDCCH，这样就可以使终端设备达到节省功耗的目的。其中，终端设备处于“唤醒状态”还可以称为终端设备处于“激活时间段”，终端设备处于“睡眠状态”还可以称为终端设备处于“非激活时间段”。目前，终端设备保持“唤醒状态”的时间段和终端设备保持“睡眠状态”的时间段构成一个CDRX周期，或者说，终端设备前一次进入“唤醒状态”的时间点与终端设备下一次进入“唤醒状态”的时间点之间的间隔为一个CDRX周期。目前定义的CDRX机制中，CDRX周期均为整数。
为了节省终端设备的功耗，可以为运行XR业务的终端设备配置CDRX机制。但是，目前XR业务中的下行帧具有周期特性，且业务周期均为小数。例如业务帧率为120fps时，一帧的业务周期为8.33毫秒(ms)，业务帧率为60fps时，一帧的业务周期为16.67ms。而CDRX周期均为整数(例如6ms、7ms、8ms、10ms……)，所以，为运行XR业务的终端设备配置CDRX机制时，即使为终端设备配置与XR业务的业务周期最接近的CDRX周期，例如XR业务的业务周期为8.33ms时，配置CDRX周期为8ms，终端设备的CDRX周期与XR业务的业务周期也无法匹配。或者说，终端设备进入“唤醒状态”，可以传输数据的时间与有待传输的XR业务数据的时间不匹配。其中，终端设备的CDRX周期与XR业务的业务周期不匹配会出现以下情况：终端设备处于“唤醒状态”时，无XR业务的业务帧待传输，导致终端设备功耗浪费。以及，有待传输的XR业务的业务帧时，终端设备处于“睡眠状态”无法接收，导致XR业务的时延不满足XR业务对时延的要求。
综上，按照现有的技术方案，终端设备的CDRX周期与XR业务的业务周期不匹配，会导致终端设备功耗浪费或者不能满足XR业务对时延的要求等问题。因此，如何使终端设备的CDRX周期可以匹配XR业务的业务周期，是目前亟待解决的问题。

具体实施方式
详细描述本申请实施例之前，为了便于理解本申请实施例的技术方案，首先给出本申请相关技术的简要介绍如下。
1、CDRX机制
CDRX机制是一种有效的节能技术，当为终端设备配置CDRX时，可以让终端设备在某些时候进入睡眠期，此时终端设备处于“睡眠态”，或者称为“非激活时间段”，终端设备可以不必监听PDCCH。而需要监听PDCCH来接收下行的业务数据的时候，则从“睡眠态”中唤醒进入“激活态”，也就是进入了激活时间段。这样就可以使终端设备达到省电的目的。
一个典型的CDRX周期如图1所示：
激活时间段：终端设备被唤醒之后，终端设备进入一个固定时长的激活时间段，该固定时长的激活时间段可以称为on-duration。如果终端设备在on-duration期间接收到调度的PDCCH，那么终端设备将保持在被唤醒状态，并延长激活时间段。on-duration的时长为网络设备为终端设备配置的。
非激活时间段：这段时间是CDRX机制中的睡眠时间，即终端设备为了省电，进入了睡眠而不监听PDCCH的时间。
CDRX周期：on-duration的重复周期，即终端设备前一次进入激活时间段的时刻与终端设备下一次进入激活时间段的时刻之间间隔的时长。一个CDRX周期由激活时间段以及非激活时间段组成。
目前，CDRX周期是网络设备通过无线资源控制(radio resource control，RRC)消息半静态配置在终端设备中的固定值，协议规定可以配置的CDRX周期的值均为整数。此外，网络设备为终端设备配置CDRX周期时，还可以指示配置的CDRX周期是长周期还是短周期。例如RRC消息包括的short DRX字段指示配置的10ms的CDRX周期为短周期。
其中，CDRX周期为长周期或短周期与终端设备进入激活时间段的时刻相关。以下介绍终端设备如何确定终端设备进入激活时间段的时刻。
目前的CDRX机制中，终端设备通过以下公式确定终端设备进入激活时间段的时刻：
当CDRX周期(drx-cycle)为长周期(long DRX cycle)时：[(SFN×10)+subframe number]modulo(drx-cycle)＝drx-StartOffset；公式(1)
当CDRX周期(drx-cycle)为短周期(short DRX cycle)时：[(SFN×10)+subframe number]modulo(drx-cycle)＝(drx-StartOffset)modulo(drx-cycle)公式(2)
其中，SFN表示终端设备进入激活时间段的系统帧号(system frame number)；subframe number表示终端设备进入激活时间段的系统帧号对应的系统帧内的子帧号；drx-cycle表示终端设备的CDRX周期；drx-StartOffset表示终端设备进入激活时间段前的子帧偏移。
上述参数中，drx-cycle的取值为网络设备配置的固定整数，drx-StartOffset的取值同 样是网络设备配置给终端设备的固定值。SFN可以取0～1023中的任一整数。subframe number可以取0～9中的任一整数。
为了避免歧义，在此解释公式(1)或公式(2)中的运算符号modulo：a modulo b表示取a除以b得到的余数，在此统一说明，以后不再赘述。
终端设备可以根据上述参数中drx-cycle和drx-StartOffset的取值，以及终端设备当前对应的SFN和subframe number，确定满足上述公式(1)或(2)的SFN和subframe number的取值，进而根据获得的SFN和subframe number的取值，确定终端设备下一次进入激活时间段的系统帧号以及系统帧内的子帧号。示例性的，假设drx-cycle＝8，drx-StartOffset＝0，终端设备根据网络设备广播的系统消息确定终端设备当前对应的SFN＝0，subframe number＝0，CDRX周期为短周期。终端设备将drx-cycle和drx-StartOffset的取值代入公式(2)，并从SFN＝0，subframe number＝0开始对SFN和subframe number进行取值，直至取得满足上述公式(2)的SFN以及subframe number的取值。终端设备确定SFN＝0，subframe number＝0满足上述公式(2)，因此终端设备第一次进入激活时间段的时刻即为帧号为0的系统帧内子帧号0对应的时刻。终端设备第一次进入激活时间段后，再次从终端设备当前的SFN和subframe number开始确定满足上述公式(2)的SFN以及subframe number的取值，得到当SFN＝0，subframe number＝8时满足上述公式(2)。因此终端设备第一次进入激活时间段后，确定的下一次进入激活时间段的时刻(第二次进入激活时间段的时刻)为帧号为0的系统帧内子帧号8对应的时刻。以此类推，终端设备第二次进入激活时间段后，确定的下一次进入激活时间段的时刻(第三次进入激活时间段的时刻)为帧号为1的系统帧内子帧号6对应的时刻。
进一步地，终端设备确定终端设备进入激活时间段的系统帧号以及系统帧内的子帧号后，还可以根据网络设备为终端设备配置的时隙偏移(drx-slot offset)，确定子帧内终端设备进入激活时段的时刻。例如，从确定的系统帧内的子帧的起始位置开始，终端设备偏移drx-slot offset*1/32ms进入激活时间段。
随着通信技术的发展，XR业务也随之出现并不断发展。为了提升用户体验，要求运行XR业务的终端设备轻量化(例如VR眼镜)，且XR业务要求高吞吐低时延，为了实现这些要求，终端设备运行XR业务所需的功耗较高，因此有课题指出如何降低XR业务的功耗是重点研究方向。
为了节省运行XR业务的终端设备的功耗，可以为运行XR业务的终端设备配置CDRX机制。但是，目前XR业务中的下行帧具有周期特性，且业务周期均为小数。例如业务帧率为120fps时，一帧的业务周期为8.33ms，业务帧率为60fps时，一帧的业务周期为16.67ms。而目前可以为终端设备配置的CDRX周期均为整数。所以，为运行XR业务的终端设备配置CDRX机制时，即使为终端设备配置与XR业务的业务周期最接近的CDRX周期，例如XR业务的业务周期为8.33ms时，为终端设备配置8ms的CDRX周期，终端设备的CDRX周期与XR业务的业务周期也无法匹配。换言之，终端设备可以传输数据的时间与有待传输的XR业务数据的时间不匹配。例如，如图2所示，假设XR业务的业务周期为8.33ms，每隔8.33ms网络设备发送一个XR业务的下行帧。终端设备配置的CDRX周期为8ms，随着时间流逝，XR业务的业务周期与CDRX周期不匹配的程度逐渐变高，直至XR业务的下行帧的传输时间与终端设备的激活时间段完全错开。从图2可以看出，终端设备的CDRX周期与XR业务的业务周期不匹配会出现以下 情况：1、终端设备处于激活时间段时，没有待传输的XR业务数据(业务帧)，导致终端设备功耗浪费。2、有待传输的XR业务数据时，终端设备处于非激活时间段无法接收，只能在终端设备进入下一个激活时间段时才能接收，导致终端设备运行的XR业务的时延不满足XR业务对时延的要求。3、整个通信系统容量和质量下降。
综上，按照现有的技术方案，终端设备的CDRX周期与XR业务的业务周期不匹配，会导致终端设备功耗浪费或者不能满足XR业务对时延的要求等问题。因此，如何使终端设备的CDRX周期可以匹配XR业务的业务周期，是目前亟待解决的问题。

下面将结合图1至图5，以图3所示的网络设备40与任一终端设备50进行交互为例，对本申请实施例提供的终端节能方法进行展开说明。
需要说明的是，本申请实施例中，终端设备可以以子帧号的形式表示终端设备进入激活时间段的时刻。具体地，根据上文介绍的终端设备根据上述公式(1)或(2)确定终端设备进入激活时间段的时刻可知，终端设备确定满足上述公式(1)或(2)的SFN和subframe number，也可以理解为确定满足上述公式(1)或(2)的[(SFN×10)+subframe number]。因此，终端设备可以将确定的[(SFN×10)+subframe number]以子帧号的形式表示。例如，终端设备确定当SFN＝1，subframe number＝9时满足公式(1)，终端设备根据SFN×10+subframe number＝19，确定终端设备进入激活时间段的子帧号为19。其中，1子帧的长度为1ms。根据上文介绍的SFN以及subframe number的取值范围，得到本申请实施例中，终端设备进入激活时间段的子帧号的取值范围为0～10239中的任一整数。
需要说明的是，本申请实施例中，两者匹配可以理解为两者相等或者两者之间的距离在一定阈值之内。其中，一定阈值小于等于网络设备为终端设备配置的on-duration的时长。换言之，终端设备进入激活时间段的时刻与网络设备按照业务周期发送第一业务的下行帧的时刻匹配可以理解为网络设备每次下发第一业务的下行帧，终端设备都可以在on-duration期间接收到。因此，终端设备不会浪费功耗，且第一业务的下行帧不会等到终端设备下一次进入激活时间段才能被接收，可以满足第一业务对时延的要求。
需要说明的是，为了简要说明终端设备如何确定终端设备进入激活时间段的时刻，在本申请实施例中，网络设备为终端设备配置的时隙偏移(drx-slot offset)为0，在此统一说明，以后不再赘述。
以下介绍本申请实施例提供的终端节能方法，如图6所示，本申请实施例提供的终端节能方法包括如下步骤S601-S602：
S601、网络设备向终端设备发送第一信息。相对应的，终端设备接收来自网络设备的第一信息，其中，第一信息用于终端设备确定终端设备对应的第一CDRX周期。
S602、终端设备根据第一CDRX周期和第一计算规则确定终端设备进入激活时间段的时刻，其中，第一计算规则用于控制终端设备进入激活时间段的时刻与网络设备按照业务周期发送第一业务的下行帧的时刻匹配。
下面分两个具体实施例对步骤S601-S602展开进行描述。
实施例一：该方案中，终端设备接收来自网络设备的第一信息之后，可以根据第一信息确定的终端设备对应的第一CDRX周期为网络设备为终端设备配置的第一CDRX周期，其中，第一CDRX周期与第一业务的业务周期相同。换言之，网络设备可以通过第一信息为终端设备配置与第一业务的业务周期相同的第一CDRX周期。可以理解的是，终端设备根据第一信息配置第一CDRX周期后，会一直以配置的第一CDRX周期运行CDRX机制，直至第一CDRX周期被来自网络设备的信息指示改变。基于本方案，终端设备可以根据第一信息，配置与第一业务的业务周期相同的第一CDRX周期，以匹配第一业务的业务周期。
可选的，第一业务的业务周期可以为小数值，相对应的，根据第一信息配置的第一 CDRX周期为与业务周期相同的小数值。例如，第一业务为XR业务，其业务周期为8.33ms，网络设备根据第一业务的业务周期，向终端设备发送第一信息，将终端设备的第一CDRX周期配置为8.33ms。
可选的，本申请实施例一中，第一信息可以携带在RRC消息中。换言之，网络设备通过RRC消息将第一CDRX周期半静态配置在终端设备中。
本申请实施例一中，网络设备可以通过以下多种形式的第一信息中任一种第一信息，为终端设备配置第一CDRX周期：
第一信息指示第一业务的业务周期，或者第一信息指示第一CDRX周期，其中，第一信息指示的第一CDRX周期与第一业务的业务周期相同。
对于第一信息指示第一业务的业务周期的情况，具体地，第一信息用于将终端设备的第一CDRX周期配置为与第一信息指示的第一业务的业务周期相同的周期。终端设备接收到第一信息后，根据第一信息确定第一业务的业务周期，并将确定的第一业务的业务周期配置为第一CDRX周期。
对于第一信息指示第一CDRX周期的情况，具体地，第一信息用于将终端设备的第一CDRX周期配置为与第一信息指示的CDRX周期相同的周期，且第一信息指示的第一CDRX周期与第一业务的业务周期相同。
可选的，第一信息包括第一CDRX周期的数值。例如，第一业务的业务周期为8.33ms，网络设备发送的第一信息包括第一CDRX周期的取值8.33，终端设备接收到第一信息后，根据第一信息以及预先规定的第一CDRX周期的单位ms，将第一CDRX周期配置为8.33ms。
或者，可选的，第一信息包括第一CDRX周期的频率。例如，第一业务的业务周期为8.33ms，网络设备发送的第一信息包括第一CDRX周期的频率的取值120，终端设备收到第一信息后，根据预先规定的第一CDRX周期与第一CDRX周期的频率的关系：第一CDRX周期的频率为一秒内CDRX周期的次数，以及预先规定的第一CDRX周期的单位为ms，计算出第一CDRX周期为(1000/120)ms，即第一CDRX周期约等于8.33ms。终端设备根据计算结果，将第一CDRX周期配置为8.33ms。
或者，可选的，第一信息包括预设整数值，终端设备收到第一信息后，可以根据预设整数值以及预设关系，确定第一CDRX周期。例如，第一信息包括的预设整数值为整型值INTEGER，INTEGER取值为833。预先规定INTEGER与第一CDRX周期之间的关系为第一CDRX周期＝INTEGER，单位为0.01ms。终端设备根据第一信息以及预先规定的INTEGER与第一CDRX周期之间的关系，将第一CDRX周期配置为8.33ms。又例如，第一信息包括的预设整数值为枚举值ENUMERATED，ENUMERATED取值为120，预先规定ENUMERATED与第一CDRX周期之间的关系为第一CDRX周期＝1/ENUMERATED，单位为ms。终端设备根据第一信息以及预先规定的ENUMERATED与第一CDRX周期之间的关系，将第一CDRX周期配置为8.33ms。
其中，在预设关系已经确定的情况下，网络设备可以根据预设关系以及第一业务的业务周期，确定预设整数值并将包括预设整数值的第一信息发送给终端设备，以使终端设备可以根据预设关系和预设整数值，确定出与第一业务的业务周期相同的第一CDRX周期。
进一步的，该方案中，终端设备可以结合根据第一信息确定的第一CDRX周期和第 一计算规则，确定终端设备进入激活时间段的时刻。其中，第一计算规则用于控制终端设备进入激活时间段的时刻与网络设备按照业务周期发送第一业务的下行帧的时刻匹配。
一种可能的实现方式中，该方案中的第一计算规则满足如下关系：

或者，
Figure PCTCN2022114577-appb-000010
Figure PCTCN2022114577-appb-000011
其中，SFN表示终端设备进入激活时间段的系统帧号；subframe number表示终端设备进入激活时间段的系统帧号对应的系统帧内的子帧号；drx-cycle表示第一CDRX周期；drx-StartOffset表示终端设备进入激活时间段前的子帧偏移。
上述参数中，drx-StartOffset、SFN、subframe number的取值可以参考上文对公式(1)或(2)中对应参数的介绍，在此不再赘述。
为了避免歧义，在此解释上述公式(3)或(4)中的运算符号：
Figure PCTCN2022114577-appb-000012
表示对a向下取整。以后不再赘述。
本申请实施例一中，当第一CDRX周期为长周期时，第一计算规则满足上述公式(3)，当第一CDRX周期为短周期时，第一计算规则满足上述公式(4)。终端设备如何根据第一计算规则和第一CDRX周期确定终端设备进入激活时间段的时刻可参考上文对公式(1)或(2)的介绍，在此不再赘述。
一方面，不同于目前用于确定终端设备进入激活时间段的公式(1)或公式(2)计算小数值的CDRX周期时计算出的进入激活时间段的子帧号为小数值，导致终端设备无法根据小数值的子帧号确定对应的进入激活时间段的时刻，本申请实施例一中，在第一CDRX周期为小数值的情况下，终端设备可以根据上述公式(3)或(4)确定出整数值的进入激活时间段的子帧号，从而能够在确定的子帧号对应的时刻进入激活时间段。另一方面，在第一CDRX周期为整数值的情况下，终端设备根据上述公式(3)或(4)确定出终端设备进入激活时间段的时刻与终端设备根据上述公式(1)或(2)确定出终端设备进入激活时间段的时刻相同。可见，本申请实施例一提供的公式(3)或(4)可以兼容整数值的CDRX周期和小数值的CDRX周期。
为了便于理解，以下示例性的说明，本申请实施例一如何实现终端设备进入激活时间段的时刻与网络设备按照业务周期发送第一业务的下行帧的时刻匹配。假设第一业务的业务周期为8.33ms，则第一信息配置的第一CDRX周期同样为8.33ms，网络设备为终端设备配置的on-duration的时长为2ms。若第一业务的下行帧在0ms第一次发送，终端设备第一次进入激活时间段的子帧号同样为0(对应0ms)，则从0ms开始，第一业务的每一个下行帧的发送时刻和终端设备每次进入激活时间段的子帧号如下表1所示：
表1
Figure PCTCN2022114577-appb-000013
Figure PCTCN2022114577-appb-000014
上述表1中，发送第一业务的下行帧的时刻为网络设备按照第一业务的业务周期每次向终端设备发送第一业务的下行帧的时刻，单位为ms。终端设备进入激活时间段的子帧号即终端设备确定的满足上述公式(3)或(4)的[(SFN×10)+subframe number]。间隔指终端设备前一次进入激活时间段的时刻(子帧号)与下一次进入激活时间段的时刻(子帧号)之间的时长，单位为ms。
上述表1中，终端设备进入激活时间段的子帧号为终端设备根据第一CDRX周期为8.33ms和上述公式(3)或公式(4)确定的。从上表可以看出，应用本申请实施例一提供的方法后，终端设备每次进入激活时间段的时刻与对应的第一业务的下行帧的发送时刻的差值均在1ms之内，小于on-duration的时长2ms，可以理解的是，终端设备每次处于激活时间段时，均能接收到对应的第一业务的下行帧。可以看出，应用本申请实施例一的方法可以使终端设备每次进入激活时间段的时刻均与第一业务的下行帧的发送时刻相匹配，终端设备不会浪费功耗，且可以满足第一业务对时延的要求。
实施例二：该方案中，终端设备接收来自网络设备的第一信息之后，可以根据第一信息确定的终端设备对应的第一CDRX周期为终端设备根据第一信息，对为终端设备配置的CDRX周期进行调整得到的第一CDRX周期。换言之，终端设备在接收到第一信息前，网络设备为终端设备配置了CDRX周期，终端设备接收到第一信息后，根据第一信息，对配置的CDRX周期进行调整进而得到第一CDRX周期。
可选的，终端设备接收到第一信息前，配置的CDRX周期可以为网络设备通过RRC消息半静态配置在终端设备中的CDRX周期。
可选的，本申请实施例二中，第一信息可以携带在媒体接入层(media access control layer，MAC Layer)控制单元(control element，CE)消息中。换言之，网络设备可以通过MAC CE消息动态调整终端设备的CDRX周期。
需要说明的是，本申请实施例中的MAC CE可以为新定义的MAC CE，新定义的MAC CE可以理解为具有新定义的逻辑信道标识(logical channel identify，LCID)的MAC CE。或者，本申请实施例中的MAC CE也可以为复用现有的LCID，并为数据体定义新的控制规则的MAC CE。在此统一说明，往后不再赘述。
可选的，本申请实施例二中，第一信息可以携带在第一业务的下行帧包括的最后一个数据包中，终端设备在激活时间段接收到第一信息后，根据第一信息确定下一次进入激活时间段的时刻。
可选的，本申请实施例二中，若第一信息携带在第一业务的下行帧包括的最后一个数据包中，第一信息还可以用于指示终端设备在接收到该下行帧之后进入非激活时间段。换言之，终端设备在接收到第一信息后进入非激活时间段。
本申请实施例二中，第一信息可以包括网络设备配置的周期调整值，终端设备根据接收的周期调整值对配置的CDRX周期进行调整。进一步地，终端设备可以根据第一信息包括的周期调整值确定周期偏移值，再根据周期偏移值对配置的CDRX周期进行调整。
示例性的，以下介绍本申请实施例二如何将第一信息携带在MAC CE消息中。
例如，如图7所示，定义一个数据体长度为8比特(bit)的MAC CE，该MAC CE的LCID表示该MAC CE用于对配置的CDRX周期进行调整，该MAC CE的数据体的取值为N，以N的取值表示周期调整值，N的取值范围为0～255。网络设备发送该MAC CE给终端设备，终端设备接收到该MAC CE后，根据该MAC CE的LCID确定该MAC CE用于对配置的CDRX周期进行调整，进而根据N的取值以及预设的规则，确定周期偏移值。例如，N的取值为200，终端设备根据周期偏移值＝(N-127)，确定周期偏移值为73。其中，周期偏移值的正负还可以表示CDRX周期偏移的方向。例如，周期偏移值为正，表示CDRX周期在时域上往后偏移，周期偏移值为负，表示CDRX周期在时域上往前偏移。本申请实施例二中，周期偏移值的单位可以为时隙(slot)、符号(symbol)或ms。
以下介绍终端设备如何根据第一信息对配置的CDRX周期进行调整来得到第一CDRX周期。一种可能的实现方式中，终端设备在接收到第一信息前配置的CDRX周期的取值保持不变，终端设备每次接收到第一信息，均在该配置的CDRX周期的基础上进行调整来确定第一CDRX周期。这种方式可以称为非记忆式。示例性的，终端设备在接收到第一信息前配置的CDRX周期为8ms，终端设备第一次接收到第一信息后，对配置的8ms的CDRX周期进行调整得到第一CDRX周期。终端设备第二次接收到第一信息后，依然是对配置的8ms的CDRX周期进行调整得到第一CDRX周期。
一种可能的实现方式中，该实现方式中的第一计算规则满足如下关系：
[(SFN×10)+subframe number]modulo(drx-Cycle+cycle-adjust)＝drx-StartOffset；

S801、网络设备向终端设备发送第二信息。相对应的，终端设备接收来自网络设备的第二信息，第二信息用于终端设备在网络设备为终端设备配置的多个CDRX周期中确定一个或多个CDRX周期，其中，一个或多个CDRX周期用于控制终端设备进入激活时间段的时刻与网络设备按照业务周期发送第一业务的下行帧的时刻匹配。
S802、终端设备根据一个或多个CDRX周期，确定终端设备进入激活时间段的时刻。
由上述步骤S801可以看出，因为第二信息用于在网络设备为终端设备配置的多个CDRX周期中确定一个或多个CDRX周期，可见在终端设备接收第二信息之前，网络设备已经为终端设备配置了多个CDRX周期，这配置的多个CDRX周期也可以称为配置的CDRX周期池。因此可选的，在终端设备接收第二信息前，终端设备还可以接收来自网络设备的第三信息，第三信息用于网络设备为终端设备配置多个CDRX周期，其中，这配置的多个CDRX周期中包括终端设备根据第二信息确定的一个或多个CDRX周期。
具体地，网络设备发送的第三信息中，包括配置的多个CDRX周期中每个CDRX周期对应的标识信息，以及与标识信息对应的CDRX周期的配置信息。终端设备可以根据CDRX周期的标识信息以及对应的配置信息，确定需要配置的多个CDRX周期中每个CDRX周期的配置信息，进而将每个CDRX周期配置在终端设备中。

其中，CDRX-Id表示CDRX周期的标识信息，“cdrx具体配置”表示与CDRX-Id对应的CDRX周期的配置信息，例如CDRX周期的数值。
可选的，网络设备还可以在携带第三信息的消息中，携带用于指示终端设备在激活时间段内接收的下行链路控制信息(downlink control information，DCI)的类型的信息。终端设备收到该信息后，在激活时间段内接收该信息指示的类型的DCI，不接收其他类型的DCI。示例性的，该信息可以为：“dci-monitor ENUMERATED{downlink,uplink,both}//”。基于本方案，终端设备可以在激活时间段内仅盲检对应类型的DCI，从而减少盲检PDCCH的次数，节省终端设备的功耗。
网络设备为终端设备配置多个CDRX周期以后，下面分两个具体实施例对步骤S801-S802展开进行描述。
实施例三：该方案中，终端设备接收来自网络设备的第二信息之后，可以根据第二信息确定多个循环CDRX周期，这多个循环CDRX周期中每个CDRX周期对应的终端设备进入激活时间段的时刻均与网络设备按照业务周期发送第一业务的下行帧的时刻匹配。

其中，CDRX-Id表示CDRX周期的标识信息。终端设备接收到该RRC消息后，根据其中的CDRX-Id在配置的CDRX周期池中确定对应的CDRX周期，并根据CDRX-Id的顺序确定对应的CDRX周期的循环顺序。例如，上述RRC消息中CDRX-Id为1、2，终端设备接收到该RRC消息后，在配置的CDRX周期池中，将标识为1的CDRX周期以及标识为2的CDRX周期按照{1，2}的顺序确定为多个循环CDRX周期。

该方案中，终端设备确定多个循环CDRX周期后，可以按照多个循环CDRX周期的循环顺序，根据对应的CDRX周期和公式(1)或公式(2)确定终端设备进入激活时间段的时刻。具体的确定过程可参考上文对公式(1)或公式(2)的介绍，在此不再赘述。
为了便于理解，以下示例性的说明，本申请实施例三中，终端设备如何实现多个循环CDRX周期中每个CDRX周期对应的终端设备进入激活时间段的时刻均与网络设备按照业务周期发送第一业务的下行帧的时刻匹配。
假设第一业务的业务周期为8.33ms，第一业务的下行帧在0ms第一次发送，终端设备第一次进入激活时间段的子帧号同样为0(对应0ms)，终端设备在第一次进入激活时间段后，接收到第二信息，第二信息指示多个循环CDRX周期为{1，1，2}，其中1或2为CDRX周期的标识信息，终端设备根据第二信息，在配置的多个CDRX周期中确定标识为1的CDRX周期为8ms，标识为2的CDRX周期为9ms，因此终端设备按照CDRX周期为{8ms，8ms，9ms}的循环顺序，确定每次进入激活时间段的时刻。第一业务的每一个下行帧的发送时刻和终端设备每次进入激活时间段的子帧号如下表2所示：

终端设备对N1N2指示的CDRX周期和M1M2指示的CDRX周期进行调整后，得到多个循环CDRX周期，并根据N1N2与M1M2的前后顺序，确定对应的多个CDRX周期的循环顺序。
本申请实施例中，终端设备如何根据第六信息对确定的多个CDRX周期中的每个CDRX周期进行调整来得到多个循环CDRX周期可以参考上文对本申请实施例二中非记忆式的介绍，在此不再赘述。
对于步骤S1202，本申请实施例中，终端设备如何根据多个循环的CDRX周期确定终端设备进入激活时间段的时刻可以参考上文对实施例三的介绍，在此不再赘述。
基于本方案，网络设备可以通过发送第六信息，使终端设备从配置的多个CDRX周期中选择多个CDRX周期进行调整并将调整后的多个CDRX周期确定为多个循环CDRX周期，终端设备根据多个循环CDRX周期确定的进入激活时间段的时刻与网络设备按照业务周期发送第一业务的下行帧的时刻匹配，终端设备不会浪费功耗，且可以满足第一业务对时延的要求。
其中，上述步骤S1201至S1202中终端设备的动作可以由图4所示的终端设备50中的处理器501调用存储器502中存储的应用程序代码以指令终端设备执行；上述步骤S1201至S1202中网络设备的动作可以由图4所示的网络设备40中的处理器401调用存储器402中存储的应用程序代码以指令网络设备执行。本实施例对此不作任何限制。
