Description

一种功耗控制方法及装置
本申请要求于2017年11月14日提交中国专利局、申请号为201711123467.5、发明名称为“一种功耗控制方法及装置”的中国专利申请的优先权，本申请还要求于2017年08月18日提交中国专利局、申请号为201710711887.9、发明名称为“一种节省移动终端功耗的方法和装置”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
本申请实施例涉及通信技术领域，尤其涉及一种功耗控制方法及装置。
背景技术
随着通信技术的快速发展，诸如手机、平板电脑、以及可穿戴设备等用户设备的使用越来越普遍。在使用过程中，用户设备大部分时间处于灭屏状态，此时用户设备中调制解调器(Modem)的功耗占比较高，且Modem的功耗主要是用户设备处于连接态时产生的。因此，需要对用户设备在灭屏时处于连接态下的功耗进行控制。
其中，用户设备处于连接态的功耗与其在连接态的非连续接收(Connected Discontinuous Reception，CDRX)的周期配置参数有关。现有技术中，存在以下两种功耗控制方法：第一种、应用处理器(Application Processor，AP)实时检测业务状态信息，并收集用户设备的移动速度信息，AP将业务状态信息和移动速度信息传递给Modem，由Modem将其上报基站，基站通过上报的业务状态信息和移动速度信息为用户设备生成新的CDRX的周期参数，并通过RRC配置给用户设备。第二种、AP实时检测业务状态信息和应用流量信息，根据检测的业务状态信息和应用流量信息生成新的CDRX的周期参数，并将其传递给Modem，Modem向基站发送CDRX请求，基站将新的CDRX的周期参数通过RRC配置给用户设备。
上述第一种方法中，用户设备和基站需要事先约定业务状态相关的业务名称标识以及是否为实时业务等信息，当需要增加新的业务名称等信息时，用户设备和基站需要同步升级，从而成本较大；此外，用户设备的业务信息和移动速度信息属于用户的个人信息，传输过程中容易造成个人信息的泄露。第二种方法中，AP为用户设备生成新的 CDRX的周期的参数，由于AP只能获取到应用层的流量信息，仅根据应用层的流量信息生成的CDRX的周期的参数准确性较低。因此，对用户设备的功耗控制效果较差。
发明内容

在第一方面的一种可能的实现方式中，当第二指示信息用于指示基站将用户设备的CDRX调整为第二周期时，第二周期为默认CDRX周期。上述可能的技术方案中，由于默认CDRX周期是由基站配置的相对较优的CDRX周期，这样不仅可以保证用户设备具有较好的通信性能，同时也不会给用户设备带来额外的功耗，提高了用户体验。
在第一方面的一种可能的实现方式中，用户设备还满足以下条件中的至少一个：用户设备上存在专用承载、用户设备的信道质量小于或等于指定阈值、用户设备处于亮屏状态或者用户设备上存在OTT通话。上述可能的技术方案中，通过确定用户设备满足上述至少一个条件后，向基站发送第二指示信息，以实现基站对CDRX的调整，从而可以提高调整CDRX的周期的准确性。

具体实施方式
在介绍本申请实施例之前，首先对本申请涉及的相关技术概念进行说明。
非连续接收(Discontinuous Reception，DRX)，是指用户设备(User Equipment，UE)在一段时间内停止监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)。由于基于包的数据流通常是突发性的，在没有数据传输的时候，通过关闭用户设备的接收电路(即停止监听PDCCH)，可以降低功耗，进而延长用户设备电源的使用时间。
其中，DRX可以分为两种，即空闲状态的非连接接收(Idle DRX)和连接态的非连续接收(Connected DRX，CDRX)。本申请主要涉及如何给用户设备配置合适的CDRX周期，达到节省功耗的目的。
如图1所示，一种连接态的非连续接收CDRX的周期中的时序示意图，具体可以包括：正持续定时器(On Duration Timer，ODT)、非激活定时器(DRX Inactive Timer，DIAT)和长周期(Long DRX Cycle，LDC)，图1中的psf是physical subframe的缩写。其中，每个LDC开始时，用户设备进入唤醒状态去监听PDCCH，唤醒持续时长为ODT时长，在监听PDCCH的过程中，该用户设备未监听到数据，该用户设备进入休眠状态直至该LDC结束；在监听PDCCH的过程中，该用户设备监听到数据，则该用户设备保持唤醒状态，继续监听PDCCH DIAT时长。此外，CDRX还可以包括短周期(Short DRX Cycle，SDC)，LDC和SDC是根据DRX类型划分的周期。当用户设备被配置为CRDX，且该CRDX包括LDC和SDC时，用户设备可以在LDC和SDC之间切换。DRX的详细描述可以参考3GPP协议36.331第5.7节Discontinuous Reception(DRX)。
具体的，用户设备被配置为CDRX，可以理解为：用户设备的调制解调器(modem)每个Long DRX Cycle(比如，160ms)就至少会被唤醒ODT的时长(比如，8ms)，当用户设备在该段时间内接收到数据时，则需要继续唤醒DIAT的时长(比如，60ms)。因此，在下行数据包比较稀疏的场景下，用户设备的modem就会频繁被唤醒且持续处于接收状态，从而导致用户设备中modem的功耗较大。
基于此，本申请实施例提供了一种功耗控制方法及装置，通过用户设备的基带处理器直接检测媒体接入控制MAC包的信息(modem流量信息)，对用户设备的功耗进行 控制。与现有技术相比，AP是无法监测到该modem流量信息的，且本申请中应用处理器AP可以不需要处于唤醒状态，基带处理器获取的modem流量信息可以直接反应用户设备的modem与基站之间进行流量信息，因此本申请提供的方法可以在保证用户设备的通信性能的前提下，减小用户设备的modem的功耗。

图4为本申请实施例提供一种功耗控制方法的流程示意图，参见图4，该方法包括以下几个步骤。
S401：基带处理器获取modem流量信息。
其中，当用户设备被配置CDRX时，CDRX的周期信息是用户设备和基站共享的，用户设备和基站按照CDRX的当前周期同步运行，即基站在该CDRX的当前周期的ODT和DIAT上，向用户设备发送数据；相应的，用户设备在此过程中接收基站发送的数据，从而用户设备中的基带处理器可以获取modem流量信息。具体的，当基带处理器获取modem流量信息时，基带处理器可以获取一段时长内的modem流量信息，该一段时长可以是指定时长(比如，1s)，也可以是CDRX的当前周期的整数倍等，本申请实施例对此不作限定。CDRX的周期参数可以包括ODT、DIAT和LDC，比如，第一周期中ODT为8ms、DIAT为60ms、LDC为160ms。
另外，该modem流量信息可以是上行授权占比、下行授权占比、上行子帧占比、下行子帧占比、上行数据流量以及下行数据流量中的一个或者多个。上行子帧占比是基于同一上行授权的实际重传次数确定的，下行子帧占比是基于同一下行授权的实际重传次数确定的。上行数据流量是基于上行授权数和每个上行授权的传输块大小TBS确定的，下行数据流量是基于下行授权数和每个下行授权的传输块大小TBS确定的。
具体的，上行授权占比是指单位时间内的实际上行授权数与理论上行授权数的比值，下行授权占比是指单位时间内的实际下行授权数与理论下行授权数的比值。上行子帧占比是指单位时间内实际上行子帧数与理论上行子帧数的比值，下行子帧占比是指单位时间内实际下行子帧数与理论下行子帧数的比值。上行数据流量是指单位时间内的上行数据流量，下行数据流量是指单位时间内的下行数据流量。其中，实际上行授权数、实际下行授权数可以由用户设备检测得到。
理论上行授权数和理论下行授权数与通信系统的类型和一个无线帧中包括的上行子帧和下行子帧的数量有关。比如，如下表1所示，以LTE的时分双工TDD系统中配比为2所示的上下行子帧为例，表1中的D表示下行子帧，S表示特殊子帧，U表示上行子帧。每5个子帧中包括1个上行子帧和4个下行子帧(S也可以作为下行子帧)，则在长周期为160ms时，每160ms内共包括32个下行子帧和128个下行子帧，即配比为2对应的理论上行授权数为32、配比为2对应的理论下行授权数为128。频分双工系统FDD中每个子帧均有上行和下行，即每5个子帧中包含5个上行子帧和5个下行子帧，则理论上行授权数和理论下行授权数均为5。
表1

Figure PCTCN2018100041-appb-000002
上行子帧占比是基于同一上行授权的实际重传次数确定的，是指上行子帧数中包括HARQ重传的子帧数量，因此上行子帧占比可能大于上行授权占比。上行数据流量是上行授权中上行子帧数与每个上行子帧的传输块大小TBS的乘积，传输块大小TBS由用于传输的资源块RB数目和每个RB的大小确定。
需要说明的是，下行子帧占比的计算与上行子帧占比的计算类似，下行数据流量的计算与上行数据流量的计算类似，具体参见上述描述，本申请实施例不再赘述。
S402：当该modem流量信息满足预设条件时，基带处理器向基站发送指示信息，该指示信息用于指示基站调整用户设备的CDRX的周期。
其中，CDRX的周期中的参数可以包括ODT、DIAT和LDC。该指示信息用于指示基站调整用户设备的CDRX的周期，具体可以为：指示信息用于指示基站调整CDRX的周期中参数的调整方向，比如，指示基站增大CDRX的周期中的某个参数，或者减小某个参数。或者，指示信息用于指示基站将CDRX的周期中的一个或者多个参数调整为某一特定的数值。
另外，当该modem流量信息满足不同的预设条件时，基带处理器向基站发送的指示信息指示基站对用户设备的CDRX的周期的调整也会所有不同，下面根据不同的预设条件进行详细描述。
第一种、该modem流量信息包括下行授权占比、下行子帧占比或者下行数据流量，该modem流量信息满足第一预设条件，即该modem流量信息小于第一阈值。
其中，该modem流量信息小于第一阈值，具体可以是指下行授权占比、下行子帧占比或者下行数据流量小于每个参数各自对应的第一阈值。每个参数对应的第一阈值可以是事先设置的，也可以是通过高层信令配置的。可选的，当该modem流量信息包括下行授权占比时，下行授权占比对应的第一阈值可以根据实际情况设置不同的数值，比如，当理论下行授权数为128、第一阈值为0.05时，由于128*0.05＝6，因此，当基带处理器检测到的实际下行授权数小于6时，则该modem流量信息满足第一预设条件，即用户设备的数据传输可以判定为稀疏。再比如，当该modem流量信息包括下行数据流量时，下行数据流量对应的第一阈值可以为10Mbps，当检测到单位时间内的下行数据流量小于10Mbps时，则该modem流量信息满足第一预设条件。
另外，当该modem流量信息包括下行授权占比时，如果基带处理器检测到的下行授权占比小于其对应的第一阈值，则确定该modem流量信息满足第一预设条件。如果基带处理器检测到的下行授权占比大于或者等于其对应的第一阈值，则确定该modem流量信息不满足第一预设条件。需要说明的是，基带处理器根据下行子帧占比、或者下行数据流量判断该modem流量信息是否满足第一预设条件的方法，与根据下行授权占比判断该modem流量信息是否满足第一预设条件的方法一致，且下行子帧占比和下行数据流量各自对应的第一阈值与下行授权占比对应的第一阈值可以不同。
具体的，当该modem流量信息满足第一预设条件时，基带处理器可以向基站发 送第一指示信息，第一指示信息可以用于指示基站调整该CDRX的周期中参数的调整方向，或者第一指示信息可以用于指示基站将该CDRX的周期中的参数调整为某个具体的数值，调整的目的是减小用户设备的功耗，即减小用户设备醒着的时间。通过该方法调整用户设备的CDRX的周期可以减小用户设备的功耗、降低电量消耗。
第一指示信息可以用于指示基站调整该CDRX的周期中参数的调整方向具体可以包括：第一指示信息用于指示基站增大用户设备的CDRX的周期中的LDC。此外，在增大CDRX的周期中长周期的情况下，第一指示信息还可以指示基站增大或减小ODT、和/或增大或减小DIAT。基带处理器通过第一指示信息，可以指示基站调整CDRX的周期中的一个参数，也可以指示基站同时调整CDRX的周期中的多个参数。
第一指示信息可以用于指示基站将该CDRX的周期中的参数调整为某个具体的数值，具体可以包括：第一指示信息用于指示基站将CDRX的周期调整为第一周期，第一周期中的LDC大于CDRX的当前周期中的LDC，比如第一指示信息用于指示基站将LDC增大为X1ms。此外，第一指示信息所指示的第一周期中还可以包括ODT和/或DIAT的信息，且第一周期中的ODT可以大于或小于CDRX的当前周期中的ODT，和/或第一周期中的DIAT可以大于或小于第一周期中的DIAT。在此情况下，当基带处理器确定该modem流量信息满足第一预设条件后，基带处理器还可以根据该modem流量信息确定第一周期中一个或者多个参数的具体数值，从而将确定的参数的具体数值通过第一指示信息发送给基站。
可选的，当该用户设备的CDRX还包括短周期(SDC)，即该用户设备的CDRX包括LDC和SDC，用户设备在LDC和SDC之间切换进行非连续接收时，第一指示信息还可以用于指示基站关闭该用户设备的CDRX中的SDC，从而使得用户设备按照LDC进行连接态的非连续接收。这样，可以进一步降低节省用户设备的功耗。
进一步的，用户设备还可以满足以下条件：用户设备上不存在专用承载、用户设备的信道质量大于指定阈值、用户设备处于灭屏状态和用户设备上不存在互联网(Over The Top，OTT)通话，即当用户设备的modem流量信息小于第一阈值，且用户设备同时满足不存在专用承载、信道质量大于指定阈值、处于灭屏状态和不存在OTT通话的所有条件时，则用户设备向基站发送第一指示信息。这样，可以更加准确的判断出当前用户设备处于空闲状态，进而在对CDRX的周期进行调整时，提高CDRX周期调整的准确性，从而进一步降低用户设备的功耗。
其中，用户设备的信道质量可以通过参考信号接收功率(Reference Signal Receiving Power，RSRP)、参考信号接收质量(Reference Signal Receiving Quality，RSRQ)、信噪比(Signal Noise Ratio，SNR)和信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)中的一个或者多个参数表示，每个参数可以对应一个指定阈值，该指定阈值可以事先进行设置，比如，当用户设备同时满足RSRP>-110dB、RSRQ>-3dB、SNR>-1dB和SINR>-1dB时，确定用户设备满足信道质量大于指定阈值的条件。
第二种、该modem流量信息包括上行授权占比、上行子帧占比或者上行数据流量，该modem流量信息满足第二预设条件，即该modem流量信息大于第二阈值。
其中，该modem流量信息大于第二阈值，具体可以是指该modem流量信息包 括的上行授权占比、上行子帧占比或者上行数据流量大于每个参数各自对应的第二阈值。每个参数各自对应的第二阈值可以是事先设置的，也可以是通过高层信令配置的。可选的，当该modem流量信息包括上行授权占比时，其对应的第二阈值可以根据实际情况设置不同的数值，比如，当理论上行授权数为32、其对应的第二阈值为0.06时，由于32*0.06≈2，因此，当基带处理器检测到的实际上行授权数大于2时，则可以确定该modem流量信息满足第二预设条件，即用户设备的传输数据可以确定为不稀疏。
另外，当该modem流量信息包括上行授权占比时，如果基带处理器检测到的上行授权占比大于其对应的第二阈值，则确定该modem流量信息满足第二预设条件。如果基带处理器检测到的上行授权占比小于或者等于其对应的第二阈值，则确定该modem流量信息不满足第二预设条件。需要说明的是，基带处理器根据上行子帧占比、或者上行数据流量判断该modem流量信息是否满足第二预设条件的方法，与根据上行授权占比判断该modem流量信息是否满足第二预设条件的方法一致，且上行子帧占比和上行数据流量各自对应的第二阈值与上行授权占比对应的第二阈值可以不同。
具体的，当该modem流量信息满足第二预设条件时，基带处理器可以向基站发送第二指示信息，第二指示信息可以用于指示基站调整该CDRX的周期中参数的调整方向，或者第二指示信息可以用于指示基站将该CDRX的周期中的参数调整为某个具体的数值，调整的目的是增大用户设备醒着的时间。
第二指示信息可以用于指示基站调整该CDRX的周期中参数的调整方向具体可以包括：第一指示信息用于指示基站减小CDRX的周期中的LDC。此外，在减小CDRX的周期中LDC的情况下，第二指示信息还可以指示基站增大或减小ODT、和/或增大或减小DIAT。用户设备通过第二指示信息，可以指示基站调整CDRX的周期中的一个参数，也可以指示基站同时调整CDRX的周期中的多个参数。这样，可以增大用户设备处于唤醒状态的时间，进而保证用户设备在modem流量信息较大时具有较好的通信性能。
第二指示信息可以用于指示基站将该CDRX的周期中的参数调整为某个具体的数值，具体可以包括：第二指示信息用于指示基站将CDRX的周期调整为第二周期，第二周期中的LDC小于用户设备的CDRX的当前周期中的LDC，比如第二指示信息用于指示基站将LDC减小为X2ms。此外，第二指示信息所指示的第二周期中还可以包括ODT和/或DIAT的信息，且第二周期中的ODT可以大于或小于CDRX的当前周期中的ODT，和/或第二周期中的DIAT可以大于或小于CDRX的当前周期中的DIAT。在此情况下，当基带处理器确定该modem流量信息满足第二预设条件后，基带处理器还可以根据该modem流量信息确定第二周期中一个或者多个参数的具体数值，从而将确定的参数的具体数值通过第二指示信息发送给基站。
可选的，当第二指示信息用于指示基站将CDRX的周期调整为第二周期时，第二周期可以为默认CDRX周期。其中，该默认CDRX周期中的各参数固定，且可以由基站配置，比如，该默认CDRX周期中的LDC为160ms、ODT为8ms、DIAT为60ms。当用户设备的modem流量信息满足第二预设条件时，基带处理器发送给基 站的第二指示信息可以用于指示基站将用户设备的CDRX的周期调整为默认CDRX周期。由于默认CDRX周期是由基站配置的相对较优的CDRX周期，这样不仅可以保证用户设备具有较好的通信性能，同时也不会给用户设备带来额外的功耗，提高了用户体验。
进一步的，用户设备还可以在满足以下信息中的至少一个条件时，向基站发送第二指示信息。至少一个条件包括：用户设备上存在专用承载、用户设备的信道质量小于或者等于指定阈值、用户设备处于亮屏状态和用户设备上存在OTT通话，即当用户设备存在专用承载、信道质量小于或者等于指定阈值、处于亮屏状态、以及存在OTT通话中的一个或者多个条件时，则用户设备向基站发送第二指示信息。这样，可以更加准确的判断出当前用户设备处于忙碌状态，进而在对CDRX的周期进行调整时，提高CDRX周期调整的准确性，保证用户设备具有较好的通信性能，提高用户体验。
具体的，如图5所示，用户设备上是否存在专用承载、以及用户设备的信道质量是否大于指定阈值，可以由用户设备中的基带处理器检测得到，具体检测方法可以参考相关技术中的描述，本申请实施例对在此不作描述。用户设备处于亮屏状态或用户设备处于灭屏状态，可以由用户设备的AP检测，并通知给基带处理器。用户设备上是否存在OTT通话可以由AP或者音频电路(比如，HIFI)通知基带处理器，AP将开启和关闭OTT通话的信息通知到音频电路，以便音频电路执行对应的语音增强功能。另外，音频电路本身也可以从是否检测到语音输入、以及输出设备是否被打开来判断是否存在OTT通话。
S403：当基站接收到指示信息时，基站根据该指示信息为用户设备确定第一周期。
基站接收用户设备发送的指示信息，该指示信息用于指示基站调整用户设备的CDRX的周期，从而基站可以根据该指示信息确定第一周期。具体的，当基带处理器获取的modem流量满足不同的预设条件时，基带处理器向基站发送的指示信息指示基站对用户设备的CDRX的周期的调整也会所有不同，从而基站基于该指示信息确定第一周期的操作也会有所不同，下面分别进行描述。
第I种、该modem流量信息包括下行授权占比、或者下行子帧占比、或者下行数据流量，该modem流量信息满足第一预设条件，即该modem流量信息小于第一阈值。S403中的第I种与S402中的第一种对应。
相应的，基站接收用户设备发送的指示信息，具体包括：基站接收用户设备发送的第一指示信息。第一指示信息可以用于指示基站增大CDRX的周期中的LDC。当第一指示信息用于指示基站增大CDRX的周期中的LDC时，基站在确定第一周期时，可以调整CDRX的周期中的LDC，对第一指示信息未指示的参数不作调整。比如，第一指示信息用于指示基站增大CDRX的周期中的LDC，则基站可以直接将LDC增大到目标值，对ODT和DIAT不作调整。当然，基站也可以对第一指示信息未指示的参数进行调整，且具体的调整由基站决定，本申请实施例对此不作限定。
或者，第一指示信息用于指示基站将CDRX的周期调整为第一周期，第一周期中的LDC大于CDRX的当前周期中的LDC。此时，第一指示信息指示了第一周期中LDC的具体数值，则基站可以根据第一指示信息所指示的具体数值对LDC进行 调整，以使调整后的第一周期中LDC的值与第一指示信息所指示的具体数值一致。类似的，当第一指示信息指示了CDRX的周期中的一个或者多个参数时，基站可以对指示的参数进行相应的调整，其他未指示的参数可以不作调整。当然，基站也可以对第一指示信息未指示的参数进行调整，且具体的调整由基站决定，本申请实施例对此不作限定。
第II种、该modem流量信息包括上行授权占比、或者上行子帧占比、或者上行数据流量，该modem流量信息满足第二预设条件，即该modem流量信息大于第二阈值。S403中的第II种与S402中的第二种对应。
相应的，基站接收用户设备发送的指示信息，具体包括：基站接收用户设备发送的第二指示信息。第二指示信息可以用于指示基站减小CDRX中的LDC。或者，第一指示信息用于指示基站将CDRX的周期调整为第一周期，第一周期中的LDC小于用户设备的CDRX的当前周期中的LDC。
需要说明的是，基站根据第二指示信息确定第一周期的方法与上述第I种情况下的方法类似，具体参见上述第I种情况中的描述，本申请实施例对此不再赘述。
进一步的，当第二指示信息还可以用于指示基站将用户设备的CDRX的周期调整为默认CDRX周期时，第二指示信息中指示的CDRX的周期中参数的具体数值可以是默认CDRX周期中参数的具体数值。此时，基站可以将默认CDRX周期确定为第一周期。
进一步的，在S402中，当用户设备确定modem流量信息满足预设条件时，基带处理器可以根据该modem流量信息为用户设备确定新的CDRX的周期，并将确定的新的CDRX的周期对应的索引信息，通过指示信息发送给基站。该周期与索引信息之间的对应关系可以事先进行设置。相应的，当基站接收到指示信息时，基站可以根据指示信息中的索引信息，从事先设置的周期与索引信息之间的对应关系，确定对应的新的CDRX的周期，该新的CDRX的周期可以为第一周期。通过索引信息可以节省用户设备与基站的交互信息。
S404：基站向用户设备发送第一配置信息，第一配置信息包括用户设备的CDRX信息。
S405：基带处理器接收基站发送的第一配置信息，并使用第一配置信息配置用户设备的CDRX的周期。
其中，第一配置信息包括的用户设备的CDRX信息可以是基站确定的第一周期的信息。当基站确定第一周期之后，基站可以通过第一配置信息将第一周期的信息发送给用户设备的基带处理器。可选的，第一配置信息可以是RRC重配消息，基站可以将第一周期中各参数的具体数值通过RRC重配消息发送给用户设备。当基带处理器接收到第一配置信息后，基带处理器可以使用第一配置信息配置用户设备的CDRX的周期，从而当用户设备的CDRX的当前周期结束后，用户设备和基站可以按照第一周期同步运行，即基站可以在第一周期中的ODT和DIAT上发送数据，相应的此时用户设备可以接收基站发送的数据。
在本申请实施例中，用户设备的基带处理器获取modem流量信息，并在该modem流量信息满足预设条件时，向基站用于指示基站调整CDRX的指示信息，以使基站 根据指示信息确定第一周期，并通过第一配置信息将用户设备的CDRX配置为第一周期，从而根据modem流量信息实现对用户设备的CDRX的调整，进而可以保证用户设备的通信性能，同时降低用户设备的功耗。
进一步的，参见图6，在S401之后，该方法还可以包括：S406-S407。其中，S406-S407与S402-S405不分先后顺序，用户设备满足何种条件即执行该条件所对应的步骤。
S406：当用户设备在连续M个用户设备的CDRX的当前周期中的modem流量信息小于第三阈值，且用户设备处于灭屏状态时，用户设备向基站发送第三指示信息，第三指示信息用于指示基站释放用户设备的RRC连接，M为正整数。
S407：当基站接收到用户设备发送的第三指示信息时，基站根据第三指示信息释放用户设备的RRC连接。
其中，第三阈值可以事先进行设置，且第三阈值可以接近于零。当用户设备在连续M个CDRX的当前周期中的modem流量信息小于第三阈值，且用户设备处于灭屏状态时，表明用户设备在一定时间内的传输数据很小或者基本无传输数据，从而基带处理器可以向基站发送用于指示基站释放RRC连接的第三指示信息，基站在接收到第三指示信息时，可以释放用户设备的RRC连接，以将用户设备从连接态调整为空闲态，从而可以减小用户设备的电源消耗，降低功耗。
可选的，当该用户设备无上行待发送数据且连续N个用户设备的CDRX的当前周期中的modem流量信息小于第四阈值(第四阈值可以事先进行设置，且第四阈值可以接近于零)时，基带处理器可以向基站发送第四指示信息，第四指示信息用于指示基站该用户设备将进入Idle DRX(Idle DRX是指用户设备处于空闲态，没有RRC连接)。当基站接收到第四指示信息时，基站可以判断该用户设备的上行和下行的缓存区，当上行和下行的缓存区为空时，则基站向用户设备发送指令，以使用户设备进入Idle DRX。当上行和下行的缓存区不为空时，则基站不处理该UE在CDRX周期的ODT和DIAT中的消息。这样，可以降低用户设备的功耗，节省降低电量，增长用户设备的电源使用时间。
进一步的，参见图7，在S401之后，该方法还可以包括：S408-S410。其中，S408-S410和S402-S405不分先后顺序，用户设备满足何种条件即执行该条件所对应的步骤。
S408：当基带处理器获取到实时业务信息时，基带处理器向基站发送第五指示信息，第五指示信息用于指示基站关闭用户设备的CDRX。
其中，该实时业务信息是指当用户设备的AP检测到用户设备的当前业务中存在实时业务时，诸如实时游戏、抢单、或者抢红包业务等，AP可以向基带处理器发送通知消息，以通知基带处理器当前存在实时业务，从而基带处理器可以向基站发送用于指示基站关闭用户设备的CDRX的第五指示信息。
S409：当基站接收到第五指示信息时，基站向用户设备发送第二配置信息，第二配置信息用于关闭用户设备的CDRX。
S410：基带处理器接收基站发送的第二配置信息，以关闭用户设备的CDRX。
由于用户设备的业务中存在实时业务，为了不影响实时业务的正常运行，当基站接收到第五指示信息时，基站可以向用户设备发送用于关闭用户设备的CDRX的第二配置信息，以关闭用户设备的CDRX，即使CDRX参数中的ODT与LDC相同。这样 使得用户设备处于一直醒着且接收数据的状态，从而实现实时业务的超低时延，提高用户设备的通信性能和用户体验。
进一步的，当基带处理器向基站发送第一指示信息、第二指示信息、第三指示信息、第三指示信息或者第五指示信息时，基带处理器可以通过CDRX请求发送上述指示信息。图8为CDRX请求的信令格式，用户设备可以使用保留的LCID发送上述指示信息。其中，该信令格式中MAC头部为R/R/E/LCID，MAC负载部分为MAC控制元素2(MAC Control element2)。MAC控制元素2为固定2字节，0～3bit为申请类型，4～7bit为终端版本号，DL-SCH对应的LCID的索引(index)为01011-11010，UL-SCH对应的LCID的索引为01011-11000。
如下表2所示，为申请类型的具体描述，请求信息类型(Request Message Type)为CDRX请求，该请求信息类似对应的索引为0001，可能的请求子类型(Request Sub-types Possible)包括：CDRX变化(CDRX Changes)、DRX非激活定时器请求(DRX In-activity Timer Request)和快速休眠(Fast Dormancy)，响应信息类型(Response Message Type)为CDRX响应(CDRX Response)，可能的响应子类型(Response Sub-types Possible)包括：接收(Accept)、否定(Deny)、RRC配置、CDRX MAC-CE命令(Command)和RRC连接释放(RRC Connection Release)，以及注释(Comments)。

如下表3所示，当请求信息类型为CDRX请求(索引为0001)时，CDRX请求本体(CDRX Request Body)的具体描述。表3中，快速释放RRC连接(Fast RRC Release Request)，外部关闭CDRX(Disable CDRX Request)，外部开启CDRX(Enable CDRX Request)，恢复默认CDRX周期(Default CDRX Cycle Request)。

Figure PCTCN2018100041-appb-000005
上述表3中，DRT-DRX Retransmission timer。相应的，则MAC CE的格式可以如图9中的(a)所示。示例性的，调大CDRX周期可以设置两档(调大1、调大2)，对应CDRX长周期分别可以为640ms、1280ms。选择依据主要是考虑尽量小于用户设备的跟踪区(Tracking Area，TA)。例如TA为1s，则CDRX长周期不能选1280ms，否则会造成每次LDC醒来后都已经TA超时，这样不利于节省功耗。
相应的，如图9中的(b)所示，网络侧的基站可以使用相同的请求信息类型发送响应消息，并使用请求本体最低位携带同意(Agreed)或否定(Denied)标识。其中，0可以表示否定，1可以表示同意。
进一步的，当用户设备根据modem流量信息，确定该modem流量信息满足哪种预设条件，从而向基站发送对应的指示信息时，用户设备可以根据图10所示的顺序进行判断。首先，判断是否符合关闭CDRX的条件，如果符合关闭CDRX的条件(是)，则申请关闭CDRX(即向基站发送第五指示信息)；如果不符合关闭CDRX的条件(否)，则判断是否符合减小CDRX或恢复为默认CDRX的周期的条件(即是否满足第二预设条件)。如果符合减小CDRX或恢复为默认CDRX的周期的条件(是)，则申请减小或恢复CDRX的周期(即向基站发送第二指示信息)；如果不符合减小或恢复CDRX的周期的条件(否)，则判断是否满足释放RRC连接的条件。如果满足释放RRC连接的条件(是)，则申请释放RRC连接(即向基站发送第三指示信息)；如果不满足释放RRC连接的条件(否)，则判断是否满足增大CDRX的条件。如果满足增大CDRX的条件(是)，则申请增大(即向基站发送第一指示信息)，如果不满足增大CDRX的条件(否)，则结束。
示例性的，当用户设备中的基带处理器向基站发送用于调整CDRX的周期的指示信息时，该指示信息中可以采用一个字段来表示表示一个独立参数，然后使用多个字段分别对应多个参数。比如，1bit表示ODT+1bit表示DIAT+2bit表示LDC+1bit表示是否携带SDC+1bit表示是否释放RRC+2bit保留＝8bit。具体每个字段的定义可以如下所示：
bit0：表示ODT，当bit0置为1时可以表示10psf，当bit0置为0时表示恢复默认值；
bit1：表示DIAT，当bit1置为1时可以表示10psf，当bit1置为0时可以表示恢复默认值；
bit2-3：表示LDC，当bit2-3置为01时表示640psf，当bit2-3置为10时可以表示1280psf，当bit2-3置为00时可以表示恢复默认值，当bit2-3置为11时可以表示保留(用XX表示)；
bit4：表示是否携带SDC，当bit4置为1时表示不携带，当bit4置为0时表示恢复默认值；
bit5：表示是否释放RRC连接，当bit5置为1时表示释放，当bit5置为0时表示不释放；

比如，当用户设备向基站发送的指示信息用于指示增大CDRX时，bit7-bit0具体可以为X X 0 1 1 0 1 1。当用户设备向基站发送的指示信息用于指示恢复默认CDRX周期 时，bit7-bit0具体可以为X X 0 0 0 0 0 0。当用户设备向基站发送的指示信息用于指示释放RRC连接时，bit7-bit0具体可以为X X 1X X X X X。
需要说明的是，上述每个字段包括的bit位数，以及不同置位时对应的表示含义仅为示例性的，并不对本申请实施例构成限定。在实际应用中，还可以通过不同的bit位数、以及不同置位时对应的表示含义也可以不同，本申请实施例对此不作限定。
在实际数据测试中，以用户设备为手机，该手机上运行不同的业务类型为例进行说明，业务类型可以包括微信通话语音、QQ通话语音、微信通话静音、QQ通话静音和待机。如下表4所示为不同业务类型在不同的设置下测量得到的数据。表4中的方向包括上行(UL)和下行(DL)，IP包个数的单位为个/秒，IP包大小的单位为字节/个，持续时间的单位为秒，制式以TDD系统下的配比2为例，授权(Grant)的单位为个/秒。
表4
Figure PCTCN2018100041-appb-000006
上述表4中，QQ通话语音在UL方向上的MAC padding包总共270个，QQ通话静音在UL方向上的MAC padding包总共965个，QQ通话语音和QQ通话静音在DL方向取决于对端为语音或静音，待机在DL方向上14秒后RRC连接被释放。
基于上述表4中数据，得到各业务类型在TDD系统的配比2下，对应的授权占比如图11所示。对于上行UL方向上，当上行占比(比如，上行授权占比)大于第一阈值X时，则确定数据不稀疏，从而在灭屏状态下OTT通话时恢复默认CDRX周期，这里X的取值应小于QQ通话静音时的授权占比10％，比如，X的取值为(10％+1％)/2＝5.5％以上。对于下行DL方向上，当下行占比(比如，下行授权占比)大于第二阈值Y时，则确定数据稀疏，从而在灭屏状态下增大CDRX的长周期，这里Y的取值应大于待机时的授权占比0.5％，比如，Y的取值为(0.5％+4.75％)/2＝2.6％以下。
上述图11是通过检测上行MAC包的占比来区分OTT语音通话和待机，但是通过MAC Padding包区分存在不确定性，如下表5所示，是结合用户设备是否在进行OTT语音通话测量得到的数据。表5中列举了部分测试数据，且已知数据包括：移动单卡(即网络运营商为移动中国，用户设备为单SIM卡手机)，空闲状态时modem的功耗为1.74mA，RRC连接态时modem的功耗为110mA。
表5
Figure PCTCN2018100041-appb-000007
需要说明的是，表5中单SIM卡手机开机建立PDN连接，激活QCI＝9默认承载，且以CMCC现网CDRX配置为ODT＝8ms、DIAT＝60ms、LDC＝160ms，调整后CDRX配置为ODT＝8ms、DIAT＝10ms、LDC＝1280ms为例进行说明。其中，从RRC建链到RRC释放为潜在收益时长。
其中，CMCC现网工作时长A＝(现网的ODT+DIAT)*调整后LDC/现网LDC＝(8+60)*1280/160＝544ms；调整CDRX后的工作时长B＝调整后(ODT+DIAT)＝8+10＝18ms；调整后LDC C＝1280ms。则每秒收益可以为(A-B)/C＝(544-18)/1280＝41.1％，绝对收益可以为(A-B)/A＝(A-B)/A＝(544-18)/544＝96.7％。
实际测试处于灭屏状态一小时，累积潜在收益时长T_cdrx≈132.7s，判决时长Count＝20s，累积空闲时长T_idle≈3286.3s，因此优化前电量为(132.7-20)*110+3286.3*1.74+1*20*110＝21305，对应21305/3600＝5.92mA，优化后电量为(132.7-20)*110/30.2+3286.3*1.74+1*20*110＝8361，对应8361/3600＝2.32mA，即灭屏时每小时节省modem功耗5.92-2.32＝3.6mA，modem功耗优化3.6/5.92＝61％，从而可增加正常使用时间0.025天＝0.6小时。
