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感知终端的选择方法、装置及通信设备进行详细地说明。
为了便于更好地理解本申请实施例，下面先介绍相关的一些技术点。
1)通信感知一体化
通信感知一体化即在同一系统中通过频谱共享与硬件共享，实现通信、感知功能一体化设计，系统在进行信息传递的同时，能够感知方位、距离、速度等信息，对目标设备或事件进行检测、跟踪、识别，通信系统与感知系统相辅相成，实现整体性能上的提升并带来更好的服务体验。
未来移动通信系统例如超5代移动通信(Beyond 5G，B5G)系统或6G系统除了具备通信能力外，还将具备感知能力。感知能力，即具备感知能力的一个或多个设备，能够通过无线信号的发送和接收，来感知目标物体的方位、距离、速度等信息，或者对目标物体、事件或环境等进行检测、跟踪、识别、成像等。未来随着毫米波、太赫兹等具备高频段大带宽能力的小基站在6G网络的部署，感知的分辨率相比厘米波将明显提升，从而使得6G网络能够提供更精细的感知服务。典型的感知功能与应用场景如表1所示。
表1
上述感知业务的服务质量要求的表述各不相同，例如智能交通、高精地图等感知通常以感知范围、距离分辨率、角度分辨率、速度分辨率和时延等来表达；飞行入侵检测感知通常以覆盖高度、感知精度、感知时延来表达；呼吸监测以感知距离、感知实时性、感知分辨率和感知精度来表达；室内入侵检测以感知距离、感知实时性、检测概率和虚警概率来表达；手势/姿态识别以感知距离、感知实时性、感知精度来表达。
上述感知业务的服务请求方式各不相同，例如基于静态区域的服务请求，以某个坐标系表示需感知内容的地理位置区域；基于动态区域的服务请求，以某个UE周围M米表示需要感知内容的地理位置范围；某个动态目标的连续感知服务请求，以某个已检测和持续位置追踪的目标表示需要感知内容的感知目标。
目前5G支持的定位方法包括下行到达时间差(Downlink Time Difference Of Arrival，DL-TDOA)方法，上行到达时间差(UL-TDOA)，多小区往返时间(Multi-Cell Round Trip Time，Multi-RTT)，下行离开角(Uplink angle-of-departure，DL-AOD)和上行到达角(Uplink angle-of-arrival，UL-AOA)，NR加强小区标识(enhancement cell ID，E-CID)定位方法。
在相关5G定位场景下，具有明确的UE ID，因此LMF和基站可基于UE ID准确找到该UE，及进行交互。在感知中是不是需要UE参与，以及哪些UE适合参与通常需要结合多个信息(如UE位置、UE感知授权信息、UE感知能力信息等)确定。对于如下三种情况下的感知业务请求，如果需要UE参与，感知业务发起和持续感知的过程中网络功能如何选择选择合适的感知终端是需要解决的问题：
情况一：基于静态区域的服务请求，如以某个坐标系表示需感知内容的地理位置区域；
情况二：基于动态区域的服务请求，如以某个UE周围M米表示需要感知内容的地理位置范围；
情况三：某个动态目标的连续感知服务请求，如以某个已检测且持续追踪位置的目标表示需要感知内容的感知目标。
进一步地，选择合适UE的重要因素之一是UE的位置信息，网络如何能 够知道感知区域的某些适合感知信号发送或接收的位置有哪些UE是需要解决的问题。除位置信息外，选择UE还需要考虑UE的感知能力、UE朝向、UE的运动状态(静止或运动速度)UE参与感知的意愿等。如果通过系统广播消息发送给UE，那么可能存在两个潜在问题：一是导致广播内容较多，二是UE自行判断是否满足多个感知条件可能会不够准确(例如UE处于室内环境时难以获得准确的全球定位系统(Global Positioning System，GPS)定位信息，可能导致位置判断不准确)。其次，有些感知测量量到感知结果的计算过程中需要UE地理位置信息作为感知测量量的标签数据。因此，当需要UE参与上述感知场景时，网络如何高效地知道感知相关区域内有哪些支持感知的UE以及UE的位置信息是需要解决的问题。

本申请实施例中，可选的，所述地理位置要求是基于某一坐标系的地理位置坐标值要求，例如以O为原点坐标值(X,Y,Z)，X、Y或Z任一方向偏差小于0.5m，或者，通过经度、维度和高度表示的坐标值要求。
本申请实施例中，可选的，所述测量量数值要求包括终端对一个或多个基站的下行信号的测量数值要求，和/或，一个或多个基站对终端的上行信号的测量数值要求。例如下行信号的测量数值要求为：UE对小区(cell)1，cell2和cell3的接收信号强度分别为-60dbm，-70dbm，-80dbm，偏差值小于3dbm；上行反之，是cell1，cell2和cell3对UE上行信号接收强度的测量数值要求。
本申请实施例中，可选的，在多天线系统中，所述测量量数值要求包括一个或多个波束的信号的测量数值要求。
上述测量量要求是依据采用的定位方法确定。下面对相关的定位方法进行简单介绍。
目前5G支持的定位方法包括下行到达时间差(Downlink Time Difference Of Arrival，DL-TDOA)方法，上行到达时间差(UL-TDOA)，多小区往返时间(Multi-Cell Round Trip Time，Multi-RTT)，下行离开角(Uplink angle-of-departure，DL-AOD)和上行到达角(Uplink angle-of-arrival，UL-AOA)，NR加强小区标识(enhancement cell ID，E-CID)定位方法。
2a)下行到达时间差方法(DL-TDOA)
如图3所示，UE获得多个TRP(eNB1、eNB2和eNB3)的下行(DownLink，DL)定位参考信号(Positioning Reference Signal，PRS)的相对到达时间，即参考信号时间差(Reference Signal Time Difference，RSTD)，之后UE或LMF根据适当的位置求解算法解出UE的地理坐标。通过DL-TDOA测量，可得到方程组：
Ri,1＝c(ti-t1)＝Ri-R1
其中，Ri为第i个TRP到UE的距离；
(xi，yi)为第i个TRP的坐标，(x0，y0)为UE的坐标；
N为TRP的个数，c为光速，ti-t1为第i个TRP与第1个TRP间的到达时间差。
2个TRP的到达时间差(到达时间差(Time Difference Of Arrival，TDOA)或RSTD)可以把UE确定在一条双曲线上。3个TRP就可以把UE限定在一个区域内。NR中，UE最多可以测量和上报256个TRP的RSTD。
2b)UL-TDOA定位方法
在UL-TDOA定位方法中，LMF基于在不同TRP处测量UE的上行定位参考信号(SRS for positioning)的UL-RTOA测量结果以及其他配置信息来估计UE位置，无需UE参与定位测量与运算。其定位原理与DL-TDOA相同，上行信号的质量由于UE参考信号较低的发射功率得不到保证。因此UE无法保证周边的基站都可以正确解析其上行参考信号，对参与定位的节点数目造成了限制，从而导致位置精度的下降。
2c)多小区往返时间(Multi-Cell Round Trip Time，Multi-RTT)方法
LTE中，E-CID技术中用于估计基站与UE的距离已采用RTT定位方法。NR中将单个RTT扩展到了多个小区和UE的RTT，即Multi-RTT。利用多个基站与UE之间的RTT测量结果联合估计UE位置。如图4所示，RTT＝(t3-t0)+(t1-t2)。
Multi-RTT相比于基于TDOA的定位技术优势在于不需要基站之间严格的同步，即不受TRP之间同步误差的影响。Multi-RTT精度主要受到上行覆盖的限制。
2d)基于角度的定位方法
下行离开角(Uplink angle-of-departure，DL-AOD)和上行到达角(Uplink angle-of-arrival，UL-AOA)都属于基于角度的定位方法，请参考图5，基于角度的定位技术的原理就是利用至少2个基站的测量角度来估计UE位置。由于基站通常具有比UE多很多的天线数量，角度测量精度更高，因此NR选择了在基站侧测量角度，即引入了下行离开角DL-AOD定位技术和上行到达角UL-AOA定位技术。DL-AoD基于UE测量的DL PRS-RSRP以及PRS波束信息(如波束方向)确定DL离开角，进一步确定UE位置。UL-AoA基于下一代基站(the next Generation Node B，gNB)测量的UL-AoA，进一步确定UE位置。
本申请实施例中，可选的，所述第一设备确定选择感知终端的第一条件 包括：
所述第一设备确定感知终端参与感知的地理位置要求；
所述第一设备确定与所述地理位置要求对应的测量量数值要求。
本申请实施例中，可选的，所述地理位置要求包括以下至少一项：
1)感知方式为基站发送感知信号，终端接收感知信号并进行感知测量时，需终端参与感知的地理位置；
例如基站A(如果感知目标区域需有多个基站协作完成，此处可扩展为多个基站的情况)发送感知信号，用于接收感知信号和测量的UE的位置区域。
2)感知方式为终端发送感知信号，基站接收感知信号并进行感知测量时，需终端参与感知的地理位置；
例如，基站A(如果感知目标区域需有多个基站协作完成，此处可扩展为多个基站的情况)接收感知信号和测量，用于发送感知信号的UE的位置区域。
3)感知方式为终端自身发送感知信号，自身接收感知信号并进行感知测量时，需终端参与感知的地理位置；
4)感知方式为终端发送感知信号，其他终端接收感知信号并进行感知测量时，需终端参与感知的地理位置。
本申请实施例中，可选的，所述第一设备根据第一感知请求信息中的感知目标区域和基站的感知范围，确定所述地理位置要求。
本申请实施例中，可选的，所述第一设备可以根据射频指纹数据库，确定与所述地理位置要求对应的测量量数值要求。当然，也不排除采用其他方式确定与所述地理位置要求对应的测量量数值要求。
射频指纹数据库应用于射频指纹定位方法中，射频指纹定位方法因定位性能好、精度高，以及射频测量量(如接收信号功率、信噪比等)易于复用现有硬件实现，成为室内定位常用的方法之一。射频指纹定位方法一般分为两个阶段：离线阶段和在线阶段。离线阶段构建一个由采样点坐标与接收信号特征组成的指纹数据库，位置坐标与接收信号特征存在一一对应的关系(在蜂窝网络中通常通过网络中长时间UE上报的测量量和位置信息来构建，如 最小化路测(Minimization of Drive Tests，MDT)或运营商自有应用程序(Application，APP)信息或人工实测)。在线阶段根据用户在某一位置处收到的事实信号特征，利用匹配算法将实时信号特征与指纹库中的指纹进行匹配，找到匹配指纹后即认为匹配指纹对应的采样点坐标就是该移动用户的位置。离线阶段也可以通过机器学习算法学习指纹库中位置坐标与信号特征之间的关系函数，在线阶段将实时信号特征带入关系函数即可得到移动用户坐标估计。其中，用来标记某位置的无线电信号特征值称为射频指纹或无线指纹，利用射频信号进行指纹定位方法称为射频指纹定位方法。射频指纹定位方法的基本原理是基于二维或三维位置空间和n维指纹信号空间的对应关系。

下面对相关的RRC状态的定义以及RRC状态之间的转换进行解释说明。
5G的RRC有三种状态：空闲(idle)态、去激活(inactive)态、连接(connected)态：
在idle态，UE与基站没有建立RRC连接，基站没有该UE的RRC上下文。从核心网的角度来看，RAN侧与核心网的连接也断开。为了减少耗电，UE在大部分时间处于休眠状态，因此无法进行数据传输。UE可周期性地唤醒以从网络接收寻呼消息(如果有的话)，当UE收到发给自己的寻呼消息后，或者UE有上行数据需要发送，则UE发起随机接入过程并建立RRC连接，从而从idle态转入connected态。Idle态的UE驻留在一个服务小区，随着UE的移动，通过小区重选机制来更换驻留的服务小区。
在connected态，UE与基站之间、基站与核心网之间建立了连接。基站为该UE保存了RRC上下文。UE可以与基站之间传输上下行数据。在连接态，移动性可由网络侧控制，即UE向网络提供邻小区测量，网络命令设备进行切换(handover)。
在LTE中，仅支持空闲态和连接态。然而，由于在一些智能手机中常常存在小数据包的频繁传输，如果按照LTE方式，会存在大量的空闲态到连接态的转换。这些转换增加了信令负载和信令延时。因此，为了减少信令负载和等待时间，在NR中引入了inactive(非激活态)状态。
在inactive态，UE与基站之间的RRC连接被释放，最后一个服务基站保存了UE的RRC上下文，并维持与核心网的UE连接。Inactive态对核心网是透明的，也就是说，从核心网的角度来看，UE仍处于连接状态。在基站使UE进入inactive态时，会给UE配置一个无线通知区域(RAN-based Notification Area，RNA)区域，UE可以在RNA区域内的小区之间移动而不用通知网络，因此，当网络需要UE进入connected态时，在RNA区域内的所有小区寻呼该UE。从去激活态转换到连接态的速度很快，且不需要核心网信令。同时，允许UE以空闲态类似的方式休眠，并且通过小区重选来处理 移动性。因此，inactive态可以被视为空闲和连接状态的混合。
上述的RRC状态是UE与基站之间的状态。UE与核心网(AMF)之间有连接管理状态(CM state)，包括：CM-IDLE和CM-CONNECTED两种状态，UE处于CM-IDLE态时，是没有该终端的N2和N3连接的，在空口，对应的UE状态是idle态。处于CM-CONNECTED状态的UE和对应的AMF之间建立了非接入层(Non-access stratum，NAS)信令连接，在空口，对应的UE状态是connected或inactive态。

下面结合具体应用场景，对本申请的感知终端的选择方法进行举例说明。
实施例1:一种基站辅助的核心网感知功能与UE间的感知终端的选择方法
本实施例中，由感知功能节点(Sensation Function，SF)确定第一条件，并UE根据第一条件基于下行测量确定是否参与感知，并向SF发送感知响应，SF根据感知响应确定感知终端。
本实施例假设SF为核心网网络功能之一，上述实施例中的第一设备是SF，第二设备与第一设备为同一SF。
请参考图8，本申请实施例的感知终端的选择方法包括以下步骤：
步骤1：感知功能节点接收感知请求，并根据感知请求确定选择感知终端的第一条件；感知请求中包括但不限于如下信息中的一项或多项：
感知目标区域：是指感知对象可能存在的位置区域，或者，需要进行成像或三维重构的位置区域；
感知对象类型：针对感知对象可能的运动特性对感知对象进行分类，每个感知对象类型中包含了典型感知对象的运动速度、运动加速度、典型RCS等信息。
感知目标对象：当对某一个或多个感知目标对象进行感知时提供感知对象的标识信息，潜在的标识方式包括：距离、速度、角度谱上的特征标识或者基于网络可识别的UE ID标识；
感知QoS：对感知目标区域或感知对象进行感知的性能指标，包括以下至少一项：感知分辨率(进一步可包括：测距分辨率、测角分辨率、测速分辨率、成像分辨率中的至少一项)等，感知精度(进一步可包括：测距精度、测角精度、测速精度、定位精度等中的至少一项)，感知范围(进一步可包括：测距范围、测速范围、测角范围、成像范围等中的至少一项)，感知时延(从感知信号发送到获得感知结果的时间间隔，或，从感知需求发起到获取感知结果的时间间隔)，感知更新速率(相邻两次执行感知并获得感知结果的时间间隔)，检测概率(在感知对象存在的情况下被正确检测出来的概率)，虚警概率(在感知对象不存在的情况下错误检测出感知目标的概率)。
步骤2：SF根据所接收到的感知请求和网络功能的感知能力信息(如基站的感知范围、AMF的感知范围、基站所支持的感知业务的信息和/或AMF所支持的感知业务的信息等)确定是否需要UE参与感知，其中UE参与感知包括UE发送感知信号、UE接收感知信号和进行感知测量、UE发送感知辅助信息(如UE摄像头或其他传感器的数据)、UE对感知测量结果进行处理中的一种或多种。如果需要UE参与，那么确定选择感知终端的第一条件。
一种确定所述第一条件的方法是SF根据感知目标区域和基站的感知范围确定感知终端参与感知的地理位置要求：
a)基站A(如果感知目标区域需有多个基站协作完成，此处可扩展为多个基站的情况)发送感知信号，用于接收感知信号和测量的UE的位置区域。
b)基站A(如果感知目标区域需有多个基站协作完成，此处可扩展为多个基站的情况)接收感知信号和测量，用于发送感知信号的UE的位置区域。
c)UE自发自收感知的位置区域。
d)UE间收发的位置区域。
SF基于射频指纹数据库获得上述地理位置要求对应的UE测量量和测量量数值要求，例如测量量数值要求为：cell1的DL RSRP在-70dbm到-75dbm区间，cell2的DL RSRP在-100dbm到-105dbm区间，cell3的DL RSRP在-89dbm到-92dbm区间。如果是多天线系统上述测量量和测量量数据可进一步表示为对cell的波束M的测量。
考虑到不同的定位方法，本实施例中所述选择感知终端的第一条件包括如下一项或多项(本实施例中，由UE自行决定是否满足第一条件，因而第一条件是UE侧对下行信号的测量量的数值要求)：
下行接收信号强度(Received Signal Strength，RSS)测量值要求，该参数是UE接收宽带功率，包括在接收机脉冲形成滤波器定义的带宽内的热噪声和接收机产生的噪声。测量的参考点为天线端口，RSS是某个时间内(如一个符号)接收到的所有信号(包括导频信号、数据信号、干扰信号和/或噪声信号等)功率的平均值。
SNR，该参数是UE接收到的有用信号的强度与接收到的噪声强度的比值。
下行RSRP测量值要求，该参数是在测量频带上参考信号功率的平均值。RSRP是某个时间内(如一个符号)承载参考信号的所有资源上接收到的信号功率的平均值。
下行RSRQ测量值要求，该参数是RSRP和RSS的比值，当RSRP和RSS测量带宽不同时需要通过一个系数来调整，如RSRQ＝N×RSRP/RSS，其中N表示RSS测量带宽中的RB数量。
下行RSTD测量值要求，该参数是接收信号到达多个TRP的时间差。
DL-AOD测量值要求，该参数是对角度进行测量，通常在多天线系统中应用，对波束的到达角或离开角进行测量。
需要说明的是，在多天线系统中上述信号进一步地可以是对每个波束上的信号进行测量。
步骤3：感知功能发送第二感知请求(即图中的感知UE选择请求)给确 定的一个或多个基站。需要说明的是，该第二感知请求消息是一个非UE关联(non-UE associated)的消息，或者说是一个全局(global)的消息。如果感知功能与基站间协议栈经AMF转发，那么该消息使用相同的方式，但是承载该消息的NGAP消息(即核心网与基站之间的协议栈消息)是非UE关联(non-UE associated)的消息，即不携带基站分配的UE NGAP ID(即RAN UE NGAP ID)；如果感知功能与基站间协议栈无需AMF转发，那么该消息可以由感知功能直接发送给对应的基站。
步骤4：基站根据所收到的第一条件，在相应的小区上广播发送第一条件，所述第一条件中还可以包括SF标识，用于触发满足第一条件且有意愿参与感知的终端发送感知响应消息。其中SF标识是接收UE感知响应消息的SF。
所述广播发送第一条件可以是通过寻呼消息发送第一条件，也可以是通过小区的系统信息发送第一条件。空闲态和去激活态的终端会监视寻呼消息和系统信息改变，从而接收寻呼消息或系统信息获取到第一条件。
第一条件可以是只发送给空闲态和去激活态的UE，也可以是发送给所有状态的UE。对于后者，对于连接态的UE，有两种发送方法：
方法1：第一条件可以被携带在专用RRC消息中发送给UE。
方法2：寻呼消息使用一个专用的RNTI，连接态的UE也监听这个专用的RNTI，从而接收到寻呼消息得到第一条件。
可选的，除了发送第一条件外，基站还可以向终端发送感知信息，比如，感知信息包括费用信息(如参与感知任务可获得多少流量或话费等)，预估的感知持续时长等，终端可以基于这些信息评估是否有意愿加入该感知任务。
步骤5：终端可根据当前已完成的下行信号测量确定自己是否满足第一条件。或者终端根据所接收到的第一条件对所述下行信号进行测量，根据测量结果确定是否满足第一条件。如果满足，然后确定是否响应SF以发送感知响应消息。可能的方法包括：
方法1：满足第一条件的终端总是响应SF以发送感知响应消息。
方法2：满足第一条件的终端可以有一定的自主权，可以根据自己的情况，比如感知费用信息、电量情况等确定是否发送感知响应消息。比如当终 端的电量低时或者感知费用低于某个门限值，即使满足第一条件，终端也可以决定不发送感知响应消息。
步骤6：终端向第一条件中所指示的SF(本实施例中，与发送第一条件的SF是同一个SF)发送感知响应消息，用于指示该终端有意愿参与该感知业务。感知响应消息可以是一个RRC消息，比如UE辅助信息消息，类似MDT指示该消息的目标接收方的IP地址。所述感知响应消息应包括UE标识，该标识是SF可识别的标识，如UE的核心网标识SUPI，全球唯一临时标识(Globally Unique Temporary Identifier，GUTI)等。
需要说明的是，当UE处于空闲态或去激活态时，终端先发起RRC连接建立或RRC连接恢复过程进入连接态。建立原因或恢复原因可以指示是响应感知请求。
可选的，感知响应消息可以包括以下信息，用于辅助SF进一步选择终端：
满足所述第一条件的测量结果，例如所测量的多个TRP的接收信号强度值；
UE朝向，UE速度，UE保持当前运动状态的时间长度(即保持当前位置、朝向、速度等运动状态不变的时间)等。如果UE未来位置已知或可预测，那么UE可提供未来某一段时间内的位置信息。当该UE支持UE间收发感知时，如果该UE有推荐可与其配合进行感知的UE，那么UE可提供推荐UE标识。
步骤7：SF可能接收到多个终端的感知响应消息，SF可以根据UE标识信息查询UE的感知能力和授权信息，获得UE授权支持哪些感知业务，从而确定感知终端。可选的，SF可根据感知响应消息中的测量结果获得UE的位置信息，用于辅助确定UE；或者基于UE ID对UE发起定位流程获得UE位置信息；或者基于UE提供的其他辅助信息来确定感知终端。
由于SF确定感知终端参与感知的地理位置要求时，涉及多种感知方式下的地理位置要求，因而SF收到的感知响应也涉及多种地理位置要求下确定的终端的感知响应，本步骤中，SF还需要确定感知方式，并从而选择与感知方式对应的感知终端。
步骤8：SF将确定的感知方式(基站发UE收，基站收UE发，UE间发 送，UE自发自收)和感知配置信息，发送给UE和基站。
步骤9：假设感知方式为基站发UE收，则基站发送感知信号，终端接收感知信号并测量。
步骤10：UE向SF发送感知测量结果。
步骤11：SF基于感知测量结果得到感知结果，并确定是否触发向第三方或核心网功能(如AMF)发送感知响应，比如，当感知结果不满足要求时，可以继续接收更多的感知测量结果，当感知结果满足需求时，触发向第三方或核心网功能(如AMF)发送感知响应，该感知响应携带感知结果。
实施例2:一种核心网感知功能和基站协同的感知终端的选择方法
本实施例中，SF确定第一条件，基站基于第一条件和上行和/或下行测量结果，确定候选感知终端列表，SF根据候选感知终端列表确定感知终端，本实施例更适用于连接态UE。
本实施例假设SF为核心网网络功能之一，第一设备是SF，第二设备与第一设备为相同的SF。
请参考图9，本申请实施例的感知终端的选择方法包括以下步骤：
步骤1：感知功能节点接收感知请求，并根据感知请求确定选择感知终端的第一条件；感知请求中包括但不限于如下信息中的一项或多项：
感知目标区域：是指感知对象可能存在的位置区域，或者，需要进行成像或三维重构的位置区域；
感知对象类型：针对感知对象可能的运动特性对感知对象进行分类，每个感知对象类型中包含了典型感知对象的运动速度、运动加速度、典型RCS等信息。
感知目标对象：当对某一个或多个感知目标对象进行感知时提供感知对象的标识信息，潜在的标识方式包括：距离、速度、角度谱上的特征标识或者基于网络可识别的UE ID标识；
感知QoS：对感知目标区域或感知对象进行感知的性能指标，包括以下至少一项：感知分辨率(进一步可包括：测距分辨率、测角分辨率、测速分辨率、成像分辨率中的至少一项)等，感知精度(进一步可包括：测距精度、测角精度、测速精度、定位精度等中的至少一项)，感知范围(进一步可包括： 测距范围、测速范围、测角范围、成像范围等中的至少一项)，感知时延(从感知信号发送到获得感知结果的时间间隔，或，从感知需求发起到获取感知结果的时间间隔)，感知更新速率(相邻两次执行感知并获得感知结果的时间间隔)，检测概率(在感知对象存在的情况下被正确检测出来的概率)，虚警概率(在感知对象不存在的情况下错误检测出感知目标的概率)。
步骤2：SF根据所接收到的感知请求和网络功能的感知能力信息(如基站的感知范围、AMF的感知范围、基站所支持的感知业务的信息和/或AMF所支持的感知业务的信息等)确定是否需要UE参与感知，其中UE参与感知包括UE发送感知信号、UE接收感知信号和进行感知测量、UE发送感知辅助信息(如UE摄像头或其他传感器的数据)、UE对感知测量结果进行处理中的一种或多种。如果需要UE参与，那么确定选择感知终端的第一条件。
一种确定所述第一条件的方法是SF根据感知目标区域和基站的感知范围确定感知终端参与感知的地理位置要求：
a)基站A(如果感知目标区域需有多个基站协作完成，此处可扩展为多个基站的情况)发送感知信号，用于接收感知信号和测量的UE的位置区域。
b)基站A(如果感知目标区域需有多个基站协作完成，此处可扩展为多个基站的情况)接收感知信号和测量，用于发送感知信号的UE的位置区域。
c)UE自发自收感知的位置区域。
d)UE间收发的位置区域。
SF基于射频指纹数据库获得上述地理位置要求对应的UE测量量和测量量数值要求，例如测量量数值要求为：cell1的DL RSRP在-70dbm到-75dbm区间，cell2的DL RSRP在-100dbm到-105dbm区间，cell3的DL RSRP在-89dbm到-92dbm区间。如果是多天线系统上述测量量和测量量数据可进一步表示为对来自UE的波束M的测量。
考虑到不同的定位方法，本实施例中所述选择感知终端的第一条件包括如下一项或多项(本实施例中，由基站决定UE是否满足第一条件，因基站可对UE的上行信号做测量，故第一条件可以是完全基于上行测量结果。同时UE也可以上报下行测量结果给基站，所以第一条件可以是上行和/或下行测量结果的数值要求)：
CIR测量值要求，该参数是信道响应的复数结果。考虑空口传输开销，一般该信道冲击响应指基站侧的UE上行信道冲击响应测量值；
上行和/或下行接收信号强度(Received Signal Strength，RSS)测量值要求，该参数是基站和/或UE接收宽带功率，包括在接收机脉冲形成滤波器定义的带宽内的热噪声和接收机产生的噪声。测量的参考点为天线端口，RSS是某个时间内(如一个符号)接收到的所有信号(包括导频信号、数据信号、干扰信号和/或噪声信号等)功率的平均值。
SNR，该参数是基站和/或UE接收到的有用信号的强度与接收到的噪声强度的比值。
上行和/或下行RSRP测量值要求，该参数是在测量频带上参考信号功率的平均值。RSRP是某个时间内(如一个符号)承载参考信号的所有资源上接收到的信号功率的平均值。
上行和/或下行RSRQ测量值要求，该参数是RSRP和RSS的比值，当RSRP和RSS测量带宽不同时需要通过一个系数来调整，如RSRQ＝N×RSRP/RSS，其中N表示RSS测量带宽中的RB数量。
上行和/或下行RSTD测量值要求，该参数是接收信号到达多个TRP的时间差。
UL-AoA和/或DL-AoD测量值要求，该参数是对角度进行测量，通常在多天线系统中应用，对波束的到达角或离开角进行测量；
UE和基站间的RTT测量值要求，假设节点1发送信号的时间是t0，节点2接收该信号的时间是t1，节点2发送信号的时间是t2，节点1接收该信号的时间是t3，RTT＝t1-t0+t3-t2＝(t3-t0)+(t1-t2)；
候选感知终端数量指示，指示所需的候选感知终端的最大数量，从而避免过多测量和数据交互。
需要说明的是，在多天线系统中上述信号进一步地可以是对每个波束上的信号进行测量。
步骤3：感知功能发送第二感知请求(即图中的感知UE选择请求)给确定的一个或多个基站。需要说明的是，该第二感知请求消息是一个非UE关联(non-UE associated)的消息，或者说是一个全局(global)的消息。如果 感知功能与基站间协议栈经AMF转发，那么该消息使用相同的方式，但是承载该消息的NGAP消息(即核心网与基站之间的协议栈消息)是非UE关联(non-UE associated)的消息，即不携带基站分配的UE NGAP ID(即RAN UE NGAP ID)；如果感知功能与基站间协议栈无需AMF转发，那么该消息可以由感知功能直接发送给对应的基站。
步骤4：基站根据所收到的第一条件，以及基站侧的上行信号测量结果和/或UE上报的下行测量结果确定哪些UE满足第一条件。可选的，如果满足条件UE数量较多，基站根据第一条件中候选感知终端数量指示，从中选择更优的候选感知终端，组成候选感知终端列表。
步骤5：基站向SF发送感知响应消息，感知响应消息包括候选感知终端列表，例如通过UE网络标识(RAN-UE-NGAP ID等)形成候选感知终端列表。可选的，感知响应消息还可以包括以下信息，用于辅助SF进一步选择终端：满足所述第一条件的测量结果，例如所测量的多个TRP的接收信号强度值。
需要说明的是，本实施例更适合于处于连接态的UE，基站侧可以对UE上行信号进行测量，可选的，基站可指示UE对下行信号进行测量和上报。
步骤6：SF根据所收到的候选感知终端列表，根据UE标识信息查询UE的感知能力和授权信息，获得UE授权支持哪些感知业务，从而确定感知终端。可选的，SF可根据感知响应消息中的测量结果获得UE的位置信息，用于辅助确定UE；或者基于UE ID对UE发起定位流程获得UE位置信息。
由于SF确定感知终端参与感知的地理位置要求时，涉及多种感知方式下的地理位置要求，因而SF收到的感知响应也涉及多种地理位置要求下确定的终端的感知响应，本步骤中，SF还需要确定感知方式，并从而选择与感知方式对应的感知终端。
步骤7：SF将确定的感知方式(基站发UE收，基站收UE发，UE间发送，UE自发自收)和感知配置信息，发送给UE和基站。假设感知方式为基站发UE收，则基站发送感知信号，终端接收感知信号并测量。UE向SF发送感知测量结果。
步骤8：SF基于感知测量结果得到感知结果，并确定是否触发向第三方 或核心网功能(如AMF)发送感知响应，比如，当感知结果不满足要求时，可以继续接收更多的感知测量结果，当感知结果满足需求时，触发向第三方或核心网功能(如AMF)发送感知响应，该感知响应携带感知结果。
实施例3:一种基站与UE间的感知终端的选择方法
本实施例中，由基站确定第一条件，并广播给UE，UE基于第一条件和下行测量确定是否参与感知，并向基站发送感知响应，基站根据感知响应确定感知终端。
本实施例中，第一设备是基站，基站根据核心网功能(如SF)发送的感知请求等，确定选择感知终端的第一条件，发送给UE。UE基于下行测量判断是否满足条件，如果满足且愿意参加，发送感知响应给基站。考虑通常核心网网络功能才能查询UE签约和授权信息，因此对于基站测而言，如果UE发送感知响应给基站则表示UE同意参与感知。可选的，基站结合上行测量等信息确定感知终端和感知配置信息。
请参考图10，本申请实施例的感知终端的选择方法包括以下步骤：
步骤1：感知功能节点接收感知请求，并根据感知请求确定选择感知终端的第一条件；感知请求中包括但不限于如下信息中的一项或多项：
感知目标区域：是指感知对象可能存在的位置区域，或者，需要进行成像或三维重构的位置区域；
感知对象类型：针对感知对象可能的运动特性对感知对象进行分类，每个感知对象类型中包含了典型感知对象的运动速度、运动加速度、典型RCS等信息。
感知目标对象：当对某一个或多个感知目标对象进行感知时提供感知对象的标识信息，潜在的标识方式包括：距离、速度、角度谱上的特征标识或者基于网络可识别的UE ID标识；
感知QoS：对感知目标区域或感知对象进行感知的性能指标，包括以下至少一项：感知分辨率(进一步可包括：测距分辨率、测角分辨率、测速分辨率、成像分辨率中的至少一项)等，感知精度(进一步可包括：测距精度、测角精度、测速精度、定位精度等中的至少一项)，感知范围(进一步可包括：测距范围、测速范围、测角范围、成像范围等中的至少一项)，感知时 延(从感知信号发送到获得感知结果的时间间隔，或，从感知需求发起到获取感知结果的时间间隔)，感知更新速率(相邻两次执行感知并获得感知结果的时间间隔)，检测概率(在感知对象存在的情况下被正确检测出来的概率)，虚警概率(在感知对象不存在的情况下错误检测出感知目标的概率)。
步骤2：SF根据所接收到的感知请求和网络功能的感知能力信息(如基站的感知范围、AMF的感知范围、基站所支持的感知业务的信息和/或AMF所支持的感知业务的信息等)确定感知基站，可选的，SF还确定是否需要UE参与感知，当然，也可以由基站确定是否需要UE参与感知。
步骤3：SF发送感知请求给前述确定的一个或多个基站。需要说明的是，该感知请求消息是一个非UE关联(non-UE associated)的消息，用于指示基站完成感知，选择哪些感知终端由基站确定。
步骤4：基站根据所接收到的感知请求(如感知目标区域、感知QoS等)确定是否需要UE参与感知，其中UE参与感知包括UE发送感知信号、UE接收感知信号和进行感知测量、UE发送感知辅助信息(如UE摄像头或其他传感器的数据)、UE对感知测量结果进行处理中的一种或多种。如果需要UE参与，那么确定选择感知终端的第一条件。
一种确定所述第一条件的方法是基站根据感知目标区域确定感知终端参与感知的地理位置要求：
a)基站A(如果感知目标区域需有多个基站协作完成，此处可扩展为多个基站的情况)发送感知信号，用于接收感知信号和测量的UE的位置区域。
b)基站A(如果感知目标区域需有多个基站协作完成，此处可扩展为多个基站的情况)接收感知信号和测量，用于发送感知信号的UE的位置区域。
基站基于射频指纹数据库获得上述地理位置要求对应的UE测量量和测量量数值要求，例如测量量数值要求为：cell1的DL RSRP在-70dbm到-75dbm区间，cell2的DL RSRP在-100dbm到-105dbm区间，cell3的DL RSRP在-89dbm到-92dbm区间。如果是多天线系统上述测量量和测量量数据可进一步表示为对cell的波束M的测量。
考虑到不同的定位方法，本实施例中所述选择感知终端的第一条件包括如下一项或多项：
CIR测量值要求，该参数是信道响应的复数结果。考虑空口传输开销，一般该信道冲击响应指基站侧的UE上行信道冲击响应测量值。
上行和/或下行接收信号强度(Received Signal Strength，RSS)测量值要求，该参数是UE接收宽带功率，包括在接收机脉冲形成滤波器定义的带宽内的热噪声和接收机产生的噪声。测量的参考点为天线端口，RSS是某个时间内(如一个符号)接收到的所有信号(包括导频信号、数据信号、干扰信号和/或噪声信号等)功率的平均值。
CIR测量值要求，该参数是信道响应的复数结果。考虑空口传输开销，一般该信道冲击响应指基站侧的UE上行信道冲击响应测量值；
上行和/或下行RSS测量值要求，该参数是基站和/或UE接收宽带功率，包括在接收机脉冲形成滤波器定义的带宽内的热噪声和接收机产生的噪声。测量的参考点为天线端口，RSS是某个时间内(如一个符号)接收到的所有信号(包括导频信号、数据信号、干扰信号和/或噪声信号等)功率的平均值。
SNR，该参数是基站和/或UE接收到的有用信号的强度与接收到的噪声强度的比值。
上行和/或下行RSRP测量值要求，该参数是在测量频带上参考信号功率的平均值。RSRP是某个时间内(如一个符号)承载参考信号的所有资源上接收到的信号功率的平均值。
上行和/或下行参考信号接收质量(RSRQ)测量值要求，该参数是RSRP和RSS的比值，当RSRP和RSS测量带宽不同时需要通过一个系数来调整，如RSRQ＝N×RSRP/RSS，其中N表示RSS测量带宽中的RB数量。
上行和/或下行RSTD测量值要求，该参数是接收信号到达多个TRP的时间差。
DL-AoA和/或DL-AoD测量值要求，该参数是对角度进行测量，通常在多天线系统中应用，对波束的到达角或离开角进行测量；
UE和基站间的RTT测量值要求，假设节点1发送信号的时间是t0，节点2接收该信号的时间是t1，节点2发送信号的时间是t2，节点1接收该信号的时间是t3，RTT＝t1-t0+t3-t2＝(t3-t0)+(t1-t2)；
候选感知终端数量指示，指示所需的候选感知终端的最大数量，从而避 免过多测量和数据交互。
需要说明的是，在多天线系统中上述信号进一步地可以是对每个波束上的信号进行测量。
根据所确定的第一条件，如果基站基于基站侧已知信息(如上行测量结果)确定了候选UE。考虑通常核心网网络功能才能查询UE签约和授权信息，因此对于基站测而言，还应发送感知请求消息给UE，所述感知请求消息包括感知内容、感知时长、感知费用等信息，UE根据所述信息判断是否愿意参与，如果UE发送感知响应给基站则表示UE同意参与感知。
步骤5：如果基站侧的信息无法确定满足第一条件的UE，那么基站在相应的小区上广播发送第一条件，用于触发满足第一条件且有意愿参与感知的终端发送感知响应消息。进一步地，基站可以根据所确定区域在相应小区的指定波束上广播发送，避免小区覆盖范围内的UE都接收到该广播信息，节省小区广播开销和UE检测开销。
所述广播发送第一条件可以是通过寻呼消息发送第一条件，也可以是通过小区的系统信息发送第一条件。空闲态和去激活态的终端会监视寻呼消息和系统信息改变，从而接收寻呼消息或系统信息获取到第一条件。
第一条件可以是只发送给空闲态和去激活态的UE，也可以是发送给所有状态的UE。对于后者，对于连接态的UE，有两种发送方法：
方法1：第一条件可以被携带在专用RRC消息中发送给UE。
方法2：寻呼消息使用一个专用的RNTI，连接态的UE也监听这个专用的RNTI，从而接收到寻呼消息得到第一条件。
可选的，除了发送第一条件外，基站还可以向终端发送感知信息，比如，感知信息包括费用信息(如参与感知任务可获得多少流量或话费等)，预估的感知持续时长等，终端可以基于这些信息评估是否有意愿加入该感知任务。
步骤6：终端可根据当前已完成的下行信号测量确定自己是否满足第一条件。或者终端根据所接收到的第一条件对所述下行信号进行测量，根据测量结果确定是否满足第一条件。如果满足，然后确定是否响应基站以发送感知响应消息。可能的方法包括：
方法1：满足第一条件的终端总是响应基站以发送感知响应消息。
方法2：满足第一条件的终端可以有一定的自主权，可以根据自己的情况，比如感知费用信息、电量情况等确定是否发送感知响应消息。比如当终端的电量低时或者感知费用低于某个门限值，即使满足第一条件，终端也可以决定不发送感知响应消息。
步骤7：终端向基站发送感知响应消息。
步骤8：基站根据所接收到的感知响应消息和基站侧信息确定感知终端和感知配置信息。
步骤9：基站发送感知信号，终端接收感知信号并测量。或者，终端发送感知信号，基站接收并测量。
步骤10：基站和/或UE向SF发送感知测量结果。
步骤11：SF基于感知测量结果得到感知结果，并确定是否触发向第三方或核心网功能(如AMF)发送感知响应，比如，当感知结果不满足要求时，可以继续接收更多的感知测量结果，当感知结果满足需求时，触发向第三方或核心网功能(如AMF)发送感知响应，该感知响应携带感知结果。
实施例4:一种核心网网络功能、基站和UE协同的感知终端选择方法
请参考图11，本实施例中，基站确定第一条件，基于下行和/或上行测量结果确定候选感知终端列表，SF根据候选感知终端列表确定感知终端。
