目前终端设备在进行网页浏览、即时通信、游戏和视频等，通常耗电相较于一些简单的通话或数据业务会增加较多，因此让UE以及使网络设备配合UE执行相应的节能策略，以降低UE的功耗，势在必行。在目前的节能配置方法中，通常由RAN为UE配置节能策略，而由于RAN的数目是海量的，不利于集中管理和控制。
为此，本申请实施例提供一种节能配置方法，该节能配置方法可以为UE配置节能策略，从而降低UE的功耗。在本申请实施例中，可以具体由AMF或PCF等为UE配置节能策略，从而便于节能策略的集中管理和控制。下面将分为不同具体实施例分别进行介绍。
实施例一。
如图2所示，本申请实施例提供一种节能配置方法，包括：
步骤200：AMF网元确定节能策略。该节能策略中可以但不限于包括以下至少一项：UE的节能策略、RAN的节能策略、或AMF的节能策略等。应当指出，上述UE的节能策略，RAN的节能策略或AMF的节能策略实质上都是为UE配置的节能策略，只不过UE的节能策略可能需要RAN或AMF的配合。
在本申请实施例如，节能策略中可以包括至少一种节能方法，每种节能方法中包括节能方法的标识和该节能方法对应的参数。举例来说，节能策略中包括节能方法1至节能方法n。若节能方法1需要RAN和AMF的配置，则UE的节能策略中可以包括：节能方法1的标识和参数1，该参数1是UE执行所述节能方法1时，需要配置给UE的参数。RAN的节能策略中可以包括：节能方法1的标识和参数2，该参数2是UE执行所述节能方法1时，需要配置给RAN的参数。AMF的节能策略中可以包括：节能方法1的标识和参数3，该参数3是UE执行所述节能方法1时，需要配置给AMF的参数。
一种实现方式中，AMF可以根据UE的能力，确定节能策略。比如，对于某些节能方法，UE可能并不支持，则为UE配置的节能策略中可以不再包括该项节能方法等，这时AMF可以获取UE的能力，根据UE的能力确定节能策略。
步骤201：AMF向RAN发送节能策略的指示信息。可选的，该节能策略的指示信息可以携带于N2消息中。节能策略中包括至少一种节能方法，节能策略的指示信息中可以包括：节能策略中每种节能方法的名称，以及每种节能方法对应的参数。

以下示例性的，对DRX和WUS等进行介绍。
所述DRX机制可以指，可以指UE周期性的在某些时间进入睡眠状态(sleep mode)，在睡眠状态下，UE无需监听PDCCH，而需要监听的时候，则UE从睡眠状态中唤醒(wake up)，从而达到省电的目的。与DRX机制相关的定时器可以包括非活跃定时器(inactivity Timer)，长周期定时器(longcycle timer)和短周期定时器(shortcycle timer)等。例如，UE可以在非活跃定时器的运行期间，持续监听PDCCH，而不受DRX周期的控制，从而避免漏听。而长周期定时器和短周期定时器，是为了进一步降低UE的功耗，所引入的定时器。例如，在长周期定时器的运行期间，UE可以执行DRX长周期，而在短周期定时器的运行期间，UE可以执行DRX短周期等。
WUS可以指具有唤醒功能的信号。利用WUS信号可以唤醒处于休眠态的UE。由于采用上述WUS技术，允许UE处于休眠态，从而降低UE的功耗。其中，WUS可指示UE在一个或多个寻呼时机(paging occasion，PO)中接收、监听、检测或侦听(detect)用于调度寻呼消息的下行控制信息(down control information，DCI)，即寻呼DCI。或者，可描述为，WUS用于指示在PO中监听用于寻呼的DCI，或者，可描述为，WUS用于指示是否在PO中监听用于寻呼的DCI等。UE接收到WUS，可以认为UE被WUS所唤醒。唤醒信号也可以称为叫醒信号，或者激活信号等。示例的，与WUS节能方法相关的参数包括：WUS辅助信息(assistance information)。
在本申请实施例中，若上述节能策略中包括AMF的节能策略，则AMF可以根据所述节能策略的指示信息，执行对应的节能操作。若上述节能策略中包括UE的节能策略，则上述图2所示的流程，还可以包括以下可选择性步骤：
步骤202：RAN向UE发送RRC消息，该RRC消息可以是RRC重配置消息，该RRC消息用于配置UE的节能策略；
步骤203：UE向RAN发送UE辅助信息，该UE辅助信息用于通知RAN所述UE已完成节能配置。
步骤204：RAN向AMF发送节能配置完成的指示信息。
通过上述方法，可以实现由AMF配置UE的节能策略，易于对节能策略的集中管理和控制。
实施例二。
如图3所示，本申请实施例还提供一种节能方法，与上述实施例一中图2所示的节能配置方法相比，将节能策略的配置可以上移到PCF，由PCF执行节能策略的配置。 至少包括：
步骤300：AMF向PCF上报UE的能力。例如，AMF可以向PCF发送UE能力的指示信息。示例的，UE可以在初始接入过程中，向AMF上报UE的能力。例如，UE可以通过UE能力消息或UE无线能力消息等向AMF上报UE的能力等。
步骤301：PCF确定节能策略，该节能策略中可以包括以下至少一项：UE的节能策略、RAN的节能策略、或AMF的节能策略等。
示例的，PCF至少可以根据UE的能力，确定节能策略。进一步的，PCF可以根据UE的其它信息(例如签约信息)与UE的能力等条件，确定节能策略。比如，对于某些节能方法，UE的能力可能支持，但该UE可能并没有签约该项节能方法，则PCF可以在节能策略中不再为UE配置该项节能方法。可选的，PCF可以与UDM等交互，获取用于确定节能策略的UE的信息，例如UE的接入授权控制和签约数据管理等信息来确定UE的能力。
步骤302：PCF向AMF发送节能策略的指示信息。例如，PCF可以向AMF发送策略控制更新通知(policy control update notify)等，该策略控制更新通知中可以包括节能策略的指示信息。
若上述节能策略中包括AMF的节能策略，则AMF可以根据AMF节能策略的指示，执行对应的节能操作。或上述节能策略中包括RAN的节能策略和/或UE的节能策略，则上述图3所示的流程，还可以包括如下步骤：
步骤303：AMF向RAN发送RAN的节能策略和/或UE的节能策略。例如，AMF可以向RAN发送N2消息，该N2消息中包括RAN的节能策略和/或UE的节能策略的指示信息。若节能策略中包括RAN的节能策略，则RAN可以根据RAN的节能策略的指示信息，执行对应的节能操作。
若上述节能策略中包括UE的节能策略，则上述图3所示的流程，还可以包括以下步骤：
步骤304：RAN向UE发送RRC消息，该RRC消息可以为RRC重配置消息，该RRC重配置消息中包括UE的节能策略的指示信息。UE可以根据UE的节能策略，执行对应的节能操作。
步骤305：UE向RAN发送UE辅助消息，该UE辅助消息中包括UE配置节能策略完成的指示信息。
步骤306：RAN向AMF发送N2消息，该N2消息用于通知AMF所述节能策略配置完成的通知消息等。
如图4所示，本申请实施例还提供一种节能配置方法，该配置方法与上述图3所示的方法的区别在于，PCF可以直接为UE配置节能策略，包括：
步骤400：AMF向PCF上报UE的能力。
步骤401：PCF通过与UDR交互，以根据UE的能力确定节能策略。该节能策略中至少包括UE的节能策略。
步骤402：PCF向UE发送UE的节能策略的指示信息。例如，PCF可以向UE发送非接入层(non-access stratum，NAS)消息，该NAS消息可以携带UE的节能策略的指示信息，该NAS消息可以为N1消息，例如，UE配置更新命令(UE configuration  update command)等。
步骤403：UE向PCF发送节能配置完成的通知消息，该通知消息同样可以携带于NAS消息中，该NAS消息可以为N1消息，例如，UE配置更新完成(configuration update complete)。步骤403为可选步骤，这里也可以不执行步骤403，在执行完步骤402后直接执行下述步骤404。
若上述步骤401中PCF确定的节能策略中还包括AMF的节能策略和/或RAN的节能策略。则上述图4中的流程，还可以包括以下步骤：
步骤404：PCF向AMF发送AMF的节能策略和/或RNA的节能策略的指示信息。例如，PCF可以向AMF发送AM策略控制的更新通知(AM policy control update notify)，该通知中可以携带有AMF的节能策略和/或RAN的节能策略的指示信息。
步骤405：AMF向RAN发送N2消息，该N2消息中包括RAN的节能策略的指示信息。例如，AMF可以向RAN发送N2消息，该N2消息中携带有RAN的节能策略的指示信息。
图4所示的流程中还可以包括以下可选步骤：
步骤406：RAN向UE发送RRC消息，该RRC消息中可以包括N2种节能方法的指示信息。
步骤407：UE向RAN发送UE辅助消息，该辅助消息用于通知RAN所述节能策略配置完成。
步骤408：RAN向AMF发送N2消息，该N2消息用于通知AMF所述节能策略配置完成。
在图4所示的实施例中，可以采用两种方式为UE配置节能策略。例如，UE的节能策略中包括N种节能方法，将上述N种节能方法划分为两部分，分别为N1种节能方法和N2种节能方法。针对上述N1种节能方法，可以通过上述图4中步骤402和步骤403中的NAS消息配置给UE。针对剩余的N2种节能方法，可以参照上述图4中步骤405和步骤406中由RAN配置给UE。
实施例三。
本申请实施例三还提供一种节能配置方法的流程，在该流程中，第一网元可统一服务编排，向PCF、AMF或RAN等配置节能策略，所述第一网元可以为用于管理终端设备的模块或网元。其中，第一网元可以为部署有终端管理模块的网元，该终端管理模块可以单独部署，或者，可以部署在NEF或AMF等网元上。在后续描述中，以第一网元为终端管理模块为例描述。如图5所示，包括：
步骤501：第三方应用程序(3 rd application，3 rd APP)可以向终端管理模块发送节能模式的指示信息。
在本申请实施例中，所述节能模式可包括以下至少一项：极致省电模式、自动省点模式或极致性能模式等，关于上述节能模式的描述，可参见表2所示。
表2
Figure PCTCN2022093393-appb-000002
Figure PCTCN2022093393-appb-000003
在本申请实施例中，3 rd APP可以通过应用程序(application interferce，API)接口，向终端管理模块发送当前需要UE采用的省电模式的指示信息。在一种理解中，3 rd APP可以为管理UE的服务器的应用程序。比如，UE为智能电网终端，则3rd APP可以为管理智能电网终端的服务器对应的应用程序，该应用程序可以接收用户(该用户可以为智能电网终端的管理员)的指示，确定当前智能电网采用何种省电模式，且通过API接口将对应省电模式的指示信息发送给终端管理模块。
步骤502：终端管理模块根据所述节能模式的指示信息，确定节能策略，该节能策略中包括以下至少一项：UE的节能策略、AMF的节能策略，或RAN的节能策略等。
在本申请实施例中，终端管理模块可以根据节能模式的指示信息，结合UE的能力、网络能力或网络状态等信息中的至少一项进行服务编排，确定节能策略。比如，终端管理模块可以根据上述至少一项信息，对节能方法进行服务编码，确定极致省电模式包括节能方法1至M1，自动省电模式包括节能方法M2至M3，极致性能模式包括节能方法M4等。举例来说，若3rd APP通过API接口指示的省电模式，为极致省电模式，则终端管理模块确定的节能策略中包括节能方法为节能方法1至M1。可以理解的是，上述节能方法1至M1可能需要RAN和AMF等的配合，因此，节能策略中还可包括RAN和AMF需要执行的节能策略等。
在一种可能的设计中，终端管理模块可以调用AMF网元的接口，向AMF网元发送节能策略的指示信息。后续由AMF执行节能策略的配置。例如，上述图5所示的流程，还可以包括：步骤503a：终端管理模块向AMF发送配置终端节能-服务消息，该配置终端节能-服务消息中包括节能策略的指示信息。后续AMF配置节能策略的过程，可参见上述实施例一中的记载。应当指出，在本申请实施例中，AMF网元在接收到上述节能策略的指示信息时，可以直接将该节能策略的指示信息发送给RAN。或者，AMF网元还可以对从第一网元接收的节能策略做进一步处理，再转发给RAN。例如，AMF网元将从第一网元接收的节能策略称为第一节能策略。AMF网元可以对第一节能策略进行处理，获得第二节能策略；AMF网元再向接入网设备发送第二节能策略的指示信息。
在另一种可能的设计中，终端管理模块还可以调用PCF的接口，向PCF发送节能策略的指示信息。后续由PCF执行节能策略的配置。例如，上述图5所示的流程中，还可以包括：步骤503b：终端管理模块向UDR发送更新(update)消息，该更新消息中包括节能策略的指示信息。步骤504b：UDR向PCF发送通知(notify)消息，该通知消息用于向PCF发送节能策略的指示信息。PCF配置节能策略的过程，可参见实施例二中的记载。应当指出，在本申请实施例中，PCF网元在接收到上述节能策略的指示信息时，可以直接将该节能策略的指示信息发送给AMF或UE。或者，PCF网元可以对从第一网元接收的节能策略做进一步处理，再转发给AMF或UE。例如，将从第 一网元接收的节能策略称为第一节能策略。PCF网元可以对第一节能策略进行处理，获得第二节能策略；PCF网元再向AMF或UE发送第二节能策略的指示信息。
再一种可能的设计中，终端管理模块还可以调用RAN的接口，向RAN发送节能策略的指示信息。例如，上述图5所示的流程，还可以包括：步骤503c：终端管理模块向RAN发送配置终端节能消息，该配置终端节能消息中包括节能策略的指示信息。步骤504c：RAN向UE发送RRC消息，该RRC消息中包括节能策略的指示信息。
在该实施例中，第三方应用程序可以直接向终端管理模块指示节能模式，终端管理模块根据指示的节能模式以及其它信息进行服务编排，确定节能策略，后续为UE配置节能策略。由于节能方法复杂，专业度较高，而在本申请实施例中，在第三方应用程序中直接显示节能模式，而不显示复杂的节能方法，第三方应用程序的用户无需具备较高的专业水准，就可以直接在节能模式中作选择。在用户选择节能模式后，终端管理模块可以进行服务编排，确定节能策略，且向UE配置节能策略，易于实现，可有效降低用户的复杂度。
在该实施例三中，还提供一种网络架构的示意图，如图6所示，包括：
3 rd APP通过API接口向终端管理模块发送节能模式的指示信息，该节能模式可以包括极致省电模式、自动省电模式或极致性能模式等。服务管理模块可以根据3 rd APP指示的节能模式，进行服务编排，确定当前省电模式对应的节能策略。该节能策略中至少包括UE的节能策略、RAN的节能策略(可能称为AN的节能策略)、AMF的节能策略(可称为AM的节能策略)等。
关于UE的节能策略，终端管理模块可以通过UDR向PCF发送UE的节能策略，PCF可以通过NAS消息直接将UE的节能策略配置给UE，可参见上述实施例二。或者，终端管理模块也可以向RAN发送UE的节能策略，由RAN向UE配置所述节能策略。关于AMF的节能策略，即AM节能策略，终端管理模块可以通过UDR向PCF发送AMF的节能策略，PCF向AMF发送AMF的节能策略，可参见上述实施例二。或者，终端管理模式也可以将AMF的节能策略直接配置给AMF，可参见上述实施例一。关于RAN的节能策略，即AN节能策略，终端管理模块同样可以通过UDR向PCF发送RAN的节能策略，PCF经过AMF将该RAN的节能策略，发送给RAN，可参见上述实施例二。或者，终端管理模块还可以将RAN的节能策略发送给AMF，由AMF配置给RAN等。
在图6所述的结构中，终端管理模块可以管理节能策略，编排和组合各种节能方法，并向外提供省电服务的API接口。
需要说明的，针对上述实施例一至实施例三：
1、上文侧重描述了实施例一、实施例二和实施例三的区别之处，除区别之外的其它内容，可相互参见。

可以理解的是，本申请实施例中，UE、RAN、AMF、PCF或终端管理模块等可以执行本申请实施例中的部分或全部步骤，这些步骤或操作仅是示例，本申请实施例还 可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照本申请实施例呈现的不同的顺序来执行，并且有可能并非要执行本申请实施例中的全部操作。
