下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的非连接态终端的确定方法进行详细地说明。
如图2所示，本申请实施例提供一种非连接态终端的确定方法200，该方法可以由终端执行，换言之，该方法可以由安装在终端的软件或硬件来执行，该方法包括如下步骤。

所述第一上行资源可以是周期性的或者非周期性的；可以是网络侧配置的或者协议约定的；或者是根据其他上行或下行资源映射的；可以是专用的或非专用的。
可选地，所述满足条件可以包括如下1)至13)至少之一：
1)所述终端接收到第一下行指示信息。
第一下行指示信息与网络侧节能功能有关，可选地，第一下行指示信息可以用于指示如下至少之一：指示网络侧设备期望进入节能模式；指示终端执行上行发送操作；指示网络侧设备期望了解小区内终端的驻留情况等等。
可选地，所述满足条件包括终端接收到所述第一下行指示信息，所述第一下行指示信息可以通过如下至少之一接收：a)系统信息块(System Information Blocks，SIB)；b)短消息；c)预定义的下行消息，所述预定义的下行消息与网络侧节能功能有关。
可选地，所述预定义的下行消息与专用下行资源映射，该专用下行资源可以用于终端确定第一下行指示信息的内容/作用。可选地，所述专用下行资源包括以下至少一项：下行时域位置；下行频域位置；同步信号/物理广播信道信号块/同步信号块(Synchronization Signal and PBCH block，SSB)。
2)所述终端选择或重选到第一小区，所述第一小区支持或使能了网络侧节能功能。
该实施例中，所述方法还可以包括如下至少之一：a)所述终端在所述第一小区内接收系统消息，所述系统消息指示所述第一小区支持网络侧节能功能；b)所述终端接收网络侧配置的节能小区列表信息，所述节能小区列表信息包括有支持网络侧节能功能的小区的信息；所述终端根据所述节能小区列表信息确定所述第一小区支持网络侧节能功能。
可选地，终端可以通过广播消息或者专用信令(例如无线资源控制(Radio Resource Control，RRC)连接释放消息)来配置节能小区列表信息。
3)所述上行发送操作达到触发时刻，所述上行发送操作是周期性触发的。
该实施例中，所述方法还包括：所述终端获取配置信息，所述配置信息包括如下至少之一：a)所述上行发送操作的触发时间和重复周期；b)周期性定时器配置，其中，在所述周期性定时器未运行或超时的情况下，所述终端执行所述上行发送操作。
一种实施例中，网络侧可以向终端指示网络侧的节能pattern(时刻或时长，周期等)，在本网络下驻留的非连接态终端可以基于该节能pattern，在网络侧进入节能模式的时刻之前，所述终端执行所述上行发送操作，以希望阻止所述网络侧进入网络节能模式。
可选地，在周期性定时器运行期间，所述终端不执行所述上行发送操作。但是，对于终端的现有过程触发的RRC连接建立流程或RRC连接恢复流程(如上行数据到达，追踪区更新(Tracking Area Update，TAU)、无线接入网通知区域更新(RAN-based Notification Area Update，RNAU)、路由区跟新(Routing Area，RA)更新、收到下行寻呼消息)，即使在周期性定时器还在运行，UE也可以发起所述RRC连接建立流程或RRC连接恢复流程。
可选地，所述配置信息包括所述周期性定时器，所述方法还包括如下至少之一：a)所述终端在执行所述上行发送操作的情况下，启动或重启所述周期性定时器；b)所述终端在执行小区重选的情况下，停止所述周期性定时器。可选地，可以释放所述周期性定时器的相关配置；c)若所述终端收到所述周期性定时器的释放指示，则停止所述周期性定时器。
4)所述终端接收到寻呼消息。
该实施例中，网络侧设备发送寻呼消息的作用是为了确定非连接态的终端，即为了触发非连接态的终端向本网络发送上行信号。这样，确定出非连接态的终端的驻留情况后，网络侧可以采取合理的节能措施，例如，决定不进入网络节能模式；又例如，选择更合适的网络节能模式；再例如，在进入网络节能模式之前尝试将非连接态终端迁移到其他正常小区进行驻留，避免影响终端在非连接态下的正常驻留。在该实施例中，所述终端收到的寻呼消息，不是由终端自己的下行数据或下行信令触发的寻呼，而是由网络侧需求(如节能需求)而触发的寻呼。因此，此处的寻呼消息可以理解为与网络侧节能功能有关。可选地，寻呼消息中若携带了寻呼原因值，所述寻呼原因值也可以设置为与网络侧节能功能有关的取值。
可选地，所述上行发送操作包括如下至少之一：
1)发起随机接入(Random Access Channel,RACH)。
2)发送随机接入前导码(Preamble)。
3)发送无线资源控制(Radio Resource Control，RRC)连接建立请求消息。
4)发起RRC连接建立流程。
5)发送RRC连接恢复请求消息。
6)发起RRC连接恢复流程。
7)发起RRC系统消息请求流程。
8)发送RRC系统消息请求消息。
9)发送第一上行信号，所述第一上行信号用于指示所述终端在小区内的驻留情况。所述第一上行信号，可以是新引入的上行RRC消息，例如上行唤醒信号。
10)发起追踪区更新(Tracking Area Update，TAU)流程。
11)发起注册区域更新流程。
12)发起无线接入网通知区域更新(RAN-based Notification Area Update，RNAU)流程。
13)发起小区位置更新流程。
该实施例中，终端执行上行发送操作的目的可以是为了配合网络侧设备确定非连接态的终端的驻留情况(或者说配合网络侧设备测试小区负载情况)，以便确定出非连接态的终端的驻留情况后，网络侧可以采取合理的节能措施，例如，决定不进入网络节能模式；又例如，选择更合适的网络节能模式；再 例如，在进入网络节能模式之前尝试将非连接态终端迁移到其他正常小区进行驻留，避免影响终端在非连接态下的正常驻留。
以1)、2)为例，描述本实施例。终端可以在满足条件的情况下，发起随机接入，也即1)。但是随机接入包括2步RACH和4步RACH，均涉及到终端的下行信号的接收。而为了辅助网络侧进行网络节能，终端也可以不接收下行信号，因此也可以仅要求终端执行随机接入的步骤1，也即2)。
本申请实施例提供的非连接态终端的确定方法，处于非连接态的终端在满足条件的情况下执行上行发送操作，所述条件与网络侧节能功能有关，这样，网络侧设备即可基于终端的上行发送操作检测到非连接态终端的存在，进而可以采取合理的节能措施，避免影响终端性能，提升用户体验。
具体地，若网络侧设备检测到非连接态终端的存在，就可以采取合理的节能措施，例如，决定不进入网络节能模式；又例如，选择更合适的网络节能模式；再例如，在进入网络节能模式之前尝试将非连接态终端迁移到其他正常小区进行驻留，避免影响终端在非连接态下的正常驻留。
可选地，在实施例200的基础上，所述上行发送操作满足如下至少之一：
1)所述上行发送操作使用的第一上行资源是预定义的上行资源。该预定义的上行资源可以用于终端执行所述上行发送操作。
所述第一上行资源可以包括：随机接入资源；所述上行发送操作的发送时机或窗口。
所述第一上行资源可以是频域资源、时域资源、空域资源中的至少之一。
所述第一上行资源可以是周期性的或者非周期性的；可以是网络侧配置的或者协议约定的；或者是根据其他上行或下行资源映射的；可以是专用的或非专用的。
2)在所述满足条件包括接收到所述第一下行指示信息的情况下，所述上行发送操作使用的第二上行资源是根据携带所述第一下行指示信息的下行信号确定。
可选地，所述第二上行资源与所述第一下行指示信息对应的下行SSB关联，和/或，所述第二上行资源与携带所述第一下行指示信息的下行时域和/或频域资源关联。
例如，终端根据第一下行指示信息对应的SSB index确定上行使用哪个preamble发送上行。
可选地，在实施例200的基础上，所述终端在执行所述上行发送操作之后不监听网络侧对所述上行发送操作的响应；和/或，所述终端在执行所述上行发送操作的过程中不监听网络侧对所述上行发送操作的响应。
该实施例例如，终端执行的上行发送操作包括发送Preamble，终端发送Preamble后可以不监听随机接入响应消息，有利于终端节能；对于网络侧设备而言，网络侧设备也可以不发送随机接入响应消息，有利于网络侧设备节能。
可选地，所述方法还包括：若所述终端在执行所述上行发送操作之后进入连接态，则所述终端向网络侧请求RRC连接释放。
在前文各个实施例的基础上，所述上行发送操作包括有指示信息，所述指示信息用于指示所述上行发送操作的原因，所述上行发送操作的原因包括以下至少之一：
1)向网络侧指示所述终端在本小区内驻留。
2)辅助网络侧节能功能。
3)响应第一下行指示信息。
可选地，所述上行发送操作的原因通过如下至少之一来指示：所述上行发送操作所使用的上行资源(例如通过专用的非竞争随机接入(Contention Free Random Access，CFRA)资源来指示)；所述上行发送操作中携带的第一原因值，例如，RRC连接恢复请求消息中携带的恢复原因值、RRC连接建立请求消息中携带的建立原因值。
可选地，实施例200还可以包括如下步骤：所述终端向核心网设备上报第一能力，第一能力用于指示所述终端是否支持网络侧节能功能，关于第一能力的具体作用可以参见后文实施例的介绍。
为详细说明本申请实施例的实现思想，以下将结合几种具体的情况进行说明。
可以理解，只要本小区下驻留的非连接态终端向网络侧发送了上行信号，那么网络侧就得知了本小区下至少存在一个非连接态的终端。目前，非连接态终端仅当收到了下行寻呼消息、或出现了上行业务、或请求系统消息或要执行TAU或RNAU时才会发送上行信号。具体地，当收到下行寻呼或出现了上行业务或者执行TAU或RNAU时，终端会发起RRC连接建立流程或RRC连接恢复流程。若请求系统消息，终端会发起RRC系统消息请求流程。因此，可以考虑如何利用现有过程或者引入新的过程来触发本小区下非连接态终端主动向网络侧发送上行信号(即终端执行的上行发送操作)。
情况1
该实施例中，当网络侧有节能需求出现时，网络侧触发检测非连接态的终端。
该实施例可以引入新的下行指示信息，简称第一下行指示信息，例如网络负载测试指示(NW load estimation Indication)信息，终端收到第一下行指示信息后执行上行发送操作，上行发送操作可以为以下之一：
1)发起随机接入(RACH)。
2)发送随机接入前导码(Preamble)。
3)发送无线资源控制(Radio Resource Control，RRC)连接建立请求消息。
4)发起RRC连接建立流程。
5)发送RRC连接恢复请求消息。
6)发起RRC连接恢复流程。
7)发起RRC系统消息请求流程。
8)发送RRC系统消息请求消息。
9)发送第一上行信号，所述第一上行信号用于指示所述终端在小区内的驻留情况。该第一上行信号可以是新引入的上行信号，例如上行唤醒信号(UpLink Wake-Up Signal，UL WUS)或者新引入的RRC消息。
10)发起追踪区更新(Tracking Area Update，TAU)流程。
11)发起注册区域更新流程。
12)发起无线接入网通知区域更新(RAN-based Notification Area Update，RNAU)流程。
13)发起小区位置更新流程。
该实施例中，第一下行指示信息可以通过以下1)至3)的方式发送：
1)通过SIB发送(例如SIB1)。
2)通过短消息发送。
3)通过新定义的下行消息发送。考虑到一个小区下可能存在多个非连接态的终端，每个终端仅在自己的寻呼位置监听短消息，那么网络需要在不同时间重复地向多个非连接态的终端发送第一指示信息，存在效率低下的问题。那么，第一指示信息也可以通过新定义的下行消息发送，终端在特定的时频资源上监听该新定义的下行消息，例如，网络节能消息(NW Power Saving message)，提升通信效率。
可选的，新定义的下行消息可以与SSB进行映射，例如，新定义的下行消息在特定的SSB发送，或者在每个SSB轮询发送。
该实施例中，终端在接收第一下行指示信息之后可以立即执行上行发送操作，例如，在接收第一下行指示信息之后的第一时长内执行上行发送操作。
可以理解，非连接态的终端可能并不期望进入连接态，其执行上行发送操作只是为了配合网络测试小区负载情况。因此，终端执行上行发送操作后或者在所述上行发送操作的过程中可以不用监听或接收对应的下行信号或响应，或者终端能够在发送完上行信号(若进入了连接态)后快速离开连接态。
然而，从网络侧的角度而言，网络侧也会收到其他终端正常发起的RRC连接建立请求、或RRC连接恢复请求、或系统消息请求，网络侧要满足这些终端的接入需求。因此，有必要让网络侧能够分辨终端因为正常业务发起的上行发送操作，还是因为协助网络侧检测小区驻留情况的上行发送。为了解决这一问题，可以考虑以下方式：
1)如果终端的上行发送操作是在网络侧指定的上行资源上发送上行信号，例如发送特定的preamble。这样，网络可以根据终端(UE)发送的preamble/上行资源来判断UE的上行发送操作的动机。
2)UE在发起RRC连接建立请求消息或RRC连接恢复请求消息中设置特殊的建立原因值或恢复原因值。
可选的，终端执行上行发送操作所使用的上行资源与终端接收第一下行指示信息对应的下行SSB有关。例如，终端根据第一下行指示信息对应的SSB索引(index)确定使用哪个preamble发送上行。
后续的实施例一，实施例二和实施例三为对上述情况1的一些例子。
该实施例中，发送第一下行指示信息的网络侧触发条件可以为：1)在预定义的网络资源上存在的连接态用户数小于或等于第一阈值时，网络侧发起第一下行指示信息的发送。第一阈值可以为0。2)网络侧周期性发送第一下行指示信息。
情况2
该实施例可以预定义一些终端侧的上行发送操作的触发条件，可以基于终端移动性事件的触发，还可以为周期性触发。
对于基于终端移动性事件的触发的情况，考虑到非连接态终端的移动性，若非连接态终端一旦重选到支持网络节能功能的小区，终端可以主动执行上行发送操作，具体实现方式可以为：
1)终端重选到当前小区，若小区的系统消息中指示本小区为节能小区，则终端执行上行发送操作，上行发送操作的说明和方法可以参考情况1。
2)网络侧可以在释放终端时给终端配置节能小区列表，例如，在RRC连接释放消息中进行配置。当终端重选到的目标小区属于节能小区列表，则 终端立即执行上行发送操作，上行发送操作的说明和方法可以参考情况1。实施例四为上述方法的一个例子。
对于周期性触发的情况，网络侧可以通过系统消息来配置终端在本小区驻留时周期性地发送上行信息(即执行上行发送操作)。
可选的，相关的网络配置信息包括以下至少之一：
1)终端上行发送的模式(pattern)，即间隔多长时间终端应触发一次上行发送操作；每次上行发送操作可以是在预定义的发送窗口进行发送，也可以是根据配置或者预定义的映射关系确定上行发送操作的具体位置。
2)终端上行发送的周期性定时器；定时器未运行或超时时，UE触发上行发送操作。在定时器允许期间，终端可以不发送上行。一旦发送了上行，UE启动或重启定时器。一旦小区重选，终端停止定时器。可选的，删除定时器配置。
3)上行发送的资源配置。
4)网络侧的节能模式周期。例如，终端可以根据网络节能模式周期，在网络侧进入节能模式之前，向网络侧发送上行信号。
实施例六为对上述方法的一个例子。
情况3
该情况3主要介绍对现有终端(legacy UE)的解决方案。
对于网络侧而言，在本小区下驻留的可能有支持这个新功能的终端(简称new UE)和不支持这个新功能的终端(简称legacy UE)。网络侧可以采用后续实施例一至实施例四的方法来触发new UE主动执行上行发送操作，但是legacy UE由于无法解析新引入的这些配置从而无法按照期望的那样发送上行信号。
方式1：考虑到legacy UE在收到短消息时，若短消息中携带了系统信息变更指示(SI change indication)，UE会执行系统信息(System Information,SI)获取流程，若网络侧把多个SIB都设置为非广播的方式，终端在收到系统信息变更指示的情况下就会采用基于需求的系统信息(on demand SI)获取的方式来向网络侧请求系统消息。
考虑到方式1中，因为如果系统消息不是终端关心的，终端可能不会发起on demand SI请求。因此可以使用方式2。
方式2：考虑到若UE离开了RA/TA/RNA区域或收到寻呼消息时，会发起RRC连接建立或RRC连接恢复流程。追踪区(Tracking Area，TA)/无线接入网通知区域(RAN Notification Area，RNA)是网络侧在终端连接态时给配置的，也即在配置时是知道终端是new UE还是legacy UE的，基站可以针对legacy UE，避免将一些节能的小区配置到TA/RNA区里，当该legacy UE移动到该小区后就会发起TAU/RNAU。该方法详见实施例五。
可选地，对于本申请各个实施例，若网络侧已经进入了网络节能模式，则终端可以根据协议约定或者网络侧的指示来确定是否还需要按照上述规则触发/执行上行发送操作。
为详细说明本申请实施例提供的非连接态终端的确定方法，以下将结合几个具体的实施例进行说明。
实施例一
该实施例中，第一下行指示信息通过短消息(short message)发送，UE收到后发送专有物理随机接入信道(Physical Random Access  Channel,PRACH)preamble，该实施例包括如下步骤。

步骤2：该终端接收到short message。
步骤3：若short message中携带第一下行指示信息，如，NW load estimation Indication，则UE发起随机接入。
可选的，UE发送专有的PRACH preamble，以便网络侧识别终端接入的目的。专有的PRACH preamble相关配置可以通过系统消息来获取，也可以是根据协议约定的方式(例如，定义了某些资源的关联关系)来获取。可选的，UE仅发送PRACH preamble，即在发送完PRACH preamble后，不要求UE监听对应的随机接入响应(Random Access Response，RAR)。
实施例二

步骤3：若收到了NW Power Saving message或在收到的NW Power Saving message中携带了第一指示信息(NW loadestimation Indication)，则UE发起随机接入。
可选的，所述预定义的下行时域和/或频域位置可以由协议约定，或者由网络侧通过系统消息进行配置。
其他可选操作可以参照实施例一。
实施例三
该实施例中，第一下行指示信息通过short message发送，UE收到后发起RRC连接建立，该实施例包括如下步骤。
步骤1：RRC IDLE态的终端在小区1驻留。
步骤2：该终端收到了short message消息。
步骤3：若short message消息中携带了第一下行指示信息，终端发送RRC连接建立请求消息。可选的，UE在RRC连接建立请求消息中携带的连接建立原因值与第一下行指示信息有关。
步骤4：UE在发送完RRC连接建立请求消息后，在收到网络侧的RRC连接释放消息后进入RRC IDLE态，或者UE在发送完RRC连接建立请求之后自行进入到RRC IDLE态。
可选的，若网络侧配置了专用于该上行发送是的专有PRACH Preamble，UE也可以直接发送专有PRACH preamble，若网络侧没有配置该preamble，则UE执行上述的步骤3-4。
实施例四
该实施例主要介绍节能小区列表，该实施例包括如下步骤。
步骤1：终端在小区1处于连接态，收到RRC Release消息。
步骤2：RRC Release消息中携带了节能小区列表。
步骤3：终端处于RRC IDLE/INACTIVE态，在小区1驻留。
步骤4：该终端重选到了小区2。
步骤5：若终端被配置了节能小区列表，且小区2属于节能小区列表中的小区，则终端发起第一上行消息的传输，该第一上行消息可以是新引入的 RRC消息。
可以理解，使用新引入的RRC消息有助于网络侧识别终端的接入目的，从而确定如何响应终端。
可选地，考虑到终端在小区2可能驻留较长时间，网络侧也可以在配置节能小区列表时配置一个上行发送周期，来保证UE隔一段时间可以主动发送一下上行信号。
实施例五
该实施例主要介绍对legacy UE的解决方案，让Legacy UE进入到节能小区时触发移动性更新过程(以TAU为例)，该实施例包括如下步骤。
步骤1：UE向核心网上报第一能力，第一能力用于指示自己是否支持网络节能特性。
步骤2：UE被配置TA列表(list)，其中不包含节能小区1，此步骤可为网络实现。
步骤3：UE移动到节能小区1，发起RRC连接建立以执行TAU流程。
步骤4：UE在节能小区1进入连接态，后又被网络侧释放回IDLE态，TA list被网络侧更新，此时包括节能小区1，服务基站可以暂时记录该终端的标识信息，以在本小区寻呼终端。该终端标识信息可以为临时移动签约标识(5G S-Temporary Mobile Subs cription Identifier，5G-S-TMSI)，其中，S-TMSI表示MME编号(Mobility Management Entity Code，MMEC)临时用户标识(SAE-Temporary Mobile Subscriber Identity，S-TMSI)。步骤5A：UE继续驻留在小区1。
步骤6A：UE接收到小区1的寻呼消息后(此寻呼可以为小区1的基站发起的也可以是基站请求核心网发起的)，发起RRC连接建立请求。
步骤7A：UE接收到RRC连接释放消息。
步骤5B：UE重选到其他小区，网络侧可以选择在终端后续进入连接态时将节能小区1从TA区移除。
总结上述步骤，核心网支持以下操作至少之一：
1)在为终端配置TA/RA时，若终端为不支持网络节能特性的终端，那么核心网不把节能小区配置到所述终端的TA/RA中。若已在，在从TA/RA中移除节能小区。可选地，支持或想要进入节能模式的基站向核心网请求执行所述操作。
2)当终端发起了TAU/RA更新流程，且所述终端在支持节能的小区发起了TAU/RA更新流程，则核心网将所述节能小区配置到所述终端的TAU/RA中。
基于上述步骤的启发，接入网支持以下操作至少之一：
1)在为终端配置RNA时，若终端为不支持网络节能特性的终端，那么锚点基站不把节能小区配置到所述终端的RNA中。若已在，在从RNA中移除节能小区。可选地，支持或想要进入节能模式的基站向锚点基站请求执行所述操作。
2)当终端发起了RNA更新流程，且所述终端在支持节能的小区发起了RNA更新流程，则锚点基站将所述节能小区配置到所述终端的RNA中。
考虑到实际部署中，可能不会在一片区域出现大量节能小区，该方法不会导致UE因为IDLE/INACTIVE移动性而频繁发起TAU/RNAU。
实施例六
该实施例主要介绍小区级的小区更新(Cell update)，该实施例包括如下步骤。
步骤1：RRC IDLE/INACTIVE态的终端在小区1驻留。
步骤2：终端从系统消息接收第一配置信息，第一配置信息包括小区更新定时器(cell update timer)的时长配置和上行发送的资源。
步骤3：一旦收到第一配置信息，终端在给定的上行发送资源上发送上行信号，并启动cell update timer。
步骤4A：(终端继续驻留在小区1…)在cell update timer超时后，终端再次给定的上行发送资源上发送上行信号，并启动cell update timer。
步骤4B：(终端重选到小区2…)终端停止cell update timer，并删除第一配置信息。
可选地，cell update timer的取值可以小于等于TAU，RNAU，5G注册的位置更新定时器。
