本公开实施例提供了一种参考设备确定方法及装置、参数处理方法及装置及存储介质，用以提高5GNR系统中，对UE进行定位的定位精度。
其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。
此外，本公开实施例提供的技术方案可以适用于多种系统，尤其是5G系统。例如适用的系统可以是全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(Wideband Code Division  Multiple Access，WCDMA)通用分组无线业务(general packet radio service，GPRS)系统、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、高级长期演进(long term evolution advanced，LTE-A)系统、通用移动系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)系统、5G新空口(New Radio，NR)系统等。这多种系统中均包括终端设备和网络侧设备。系统中还可以包括核心网部分，例如演进的分组系统(Evolved Packet System，EPS)、5G系统(5GS)等。
本公开实施例涉及的终端设备，可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中，终端设备的名称可能也不相同，例如在5G系统中，终端设备可以称为用户设备(User Equipment，UE)。无线终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网(Core Network，CN)进行通信，无线终端设备可以是移动终端设备，如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device)，本公开实施例中并不限定。
本公开实施例涉及的网络侧设备，可以是基站，该基站可以包括多个为终端提供服务的小区。根据具体应用场合不同，基站又可以称为接入点，或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备，或者其它名称。网络侧设备可用于将收到的空中帧与网际协议(Internet Protocol，IP)分组进行相互更换，作为无线终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)通信网络。网络侧设备还可协调对空中接口的属性管理。例如，本公开实施例涉及的网络侧设备可以是全球移动通信系统(Global System for Mobile communications，GSM)或码分多址接入(Code Division Multiple Access，CDMA)中的网络侧设备(Base Transceiver Station，BTS)，也可以是带宽码分多址接入(Wide-band Code Division MultipleAccess，WCDMA)中的网络侧设备(NodeB)，还可以是长期演进(long term evolution，LTE)系统中的演进 型网络侧设备(evolutional Node B，eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站(gNB)，也可以是家庭演进基站(Home evolved Node B，HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等，本公开实施例中并不限定。在一些网络结构中，网络侧设备可以包括集中单元(centralized unit，CU)节点和分布单元(distributed unit，DU)节点，集中单元和分布单元也可以地理上分开布置。

如图1所示，本公开实施例提供了一种参考设备确定方法的流程图，所述方法应用于位置管理功能网元(Location Management Function，LMF)，所述方法包括：
步骤101，获取候选参考设备的定位参考参数。
其中，参考设备用于对目标UE进行定位参考；可选地，对于UE的服务基站(或其他为UE提供网络服务的网络侧设备，例如其他接入网设备)，可为其配置一个或多个参考设备，用于对该基站的UE进行定位时，提供定位参考功能。当存在基站对应的候选参考设备时，LMF根据候选参考设备的定位参考参数，选择其中的目标参考设备，作为该基站的参考设备。
可选地，候选参考设备和/或参考设备可以是网络侧设备或用户侧设备，网络侧设备例如基站或网络中其他设备，用户侧设备例如手机等用户终端。候选参考设备和/或参考设备可以是预先配置为参考设备的设备，也可以是未预先配置但具有作为候选参考设备和/或参考设备的能力的设备。
具体地，定位参考参数可以包括候选参考设备的位置参数和/或指示位置参数的精度指示参数等等。位置参数例如位置测量数据和/或位置估计数，在NR Rel-16的LPP协议(TS 37.355)中，定义了服务器从目标UE侧请求位置测量数据和/或位置估计的信令，利用该信令UE可以把其获取的相关定位参考参数上报给LMF。
步骤102，根据所述定位参考参数，确定所述候选参考设备中的目标参考设备。
其中，所述定位参考参数通过以下方式一至方式三中的至少一项获取：

候选参考设备可以自动向LMF上报定位参考参数。
方式二：指示第一网络侧设备向所述候选参考设备发送第一指示信息，所述第一指示 信息指示所述候选参考设备向所述LMF发送所述定位参考参数。
比如，第一网络侧设备包括基站，LMF发送指示信令给基站，由基站通过广播信令或者无线资源控制层(Radio Resource Control，RRC)专用信令触发，广播信令可以通过系统消息(System Information Block，SIB)发送。基站接收到LMF发送的指示信令后，向其覆盖区域内的所有UE发送广播消息或RRC信令，请求所有的候选参考设备(或参考设备)将其定位参考参数发送到LMF。其中，一组UE可以被预先配置为候选参考设备。
方式三：通过预设信令消息向所述候选参考设备发送第二指示信息，所述第二指示信息指示所述候选参考设备向所述LMF发送所述定位参考参数。
LMF可以向一个或多个候选参考设备发送作为专用消息的预设信令消息，该预设信令消息用于指示UE向所述LMF发送所述定位参考参数；例如：LMF触发该LMF的关联基站的覆盖范围内的所有UE首先进行一次基于UE的定位(UE-based定位，例如：UL-based DL-TDOA或者UE-based DL-AOD)，让所有候选UE来上报该UE的定位参考参数；可选地，预设信令消息可以是LTE定位协议(LTE Positioning Protocol，LPP)信令消息。
LMF收到候选参考设备的定位参考参数之后，根据定位参考参数选择最优的目标参考设备，和/或根据预设的判断规则确定定位参考参数是否满足作为目标参考设备的要求。可以理解的是，本公开实施例中，对于一个服务基站，目标参考设备可以包括一个或至少两个。
确定目标参考设备后，后续对其他用户设备进行定位时，可以将目标参考设备的已知位置信息作为参考信息，例如用于估计和/或校正定位信号的发送和接收误差，定位信号可以是基站和/或收发点(Transmission-Reception Point，TRP)的定位信号，以提升定位精度。
本公开实施例中，LMF获取候选参考设备的定位参考参数；根据所述定位参考参数，确定所述候选参考设备中的目标参考设备；定位参考参数可由候选参考设备自动发送，或通过第一指示信息和/或第二指示信息获取；本公开实施例中提供了一种配置或选取参考设备的方式，且通过定位参考参数配置或选取参考设备，提升目标参考设备的配置精度或选取精度，进而提高5GNR系统中，对UE进行定位的定位精度。
并且，后续在定位过程中，可参考目标参考设备的位置信息，可进一步提高对UE进行定位的定位精度。
可选地，本公开实施例中，所述定位参考参数包括以下至少一项：

可选地，本公开实施例中，所述精度指示参数包括以下至少一项：
所述位置估计值的质量指示参数、所述位置估计值的误差范围参数、所述位置估计值的不确定度参数、所述定位方式参数的可靠性参数。
其中，质量指示参数指示该位置估计值对应的位置，作为目标参考设备的位置的质量高低；误差范围参数表示位置估计值与真实位置值之间的误差范围；所述位置估计值的不确定度参数指示该位置估计值对应的位置的不确定程度；所述定位方式参数的可靠性参数指示该定位方式参数对应的定位方式的可靠性程度。
可选地，对于不同的位置参数，其精度指示参数可预先设定；比如预先设定每个位置参数对应的精度指示参数的具体值。
在一个可选实施例中，若所述精度指示参数包括所述位置估计值的误差范围参数，则所述误差范围参数包括第一误差范围参数和/或第二误差范围参数；
其中，所述第一误差范围参数包括所述候选参考设备的位置解算值的第一误差；所述第一误差包括误差取值和/或误差分辨率。
误差取值指示位置解算值对应的不确定性的最优估计值；误差分辨率指示误差取值的量化步长。
所述第二误差范围参数包括所述候选参考设备的第二误差，所述第二误差为位置解算值和/或定位测量量的误差。
可以理解的是，本公开实施例中，“测量量”表示“测量的量值”，即测量所得结果，即“定位测量量”指“定位测量的量值”；所述第二误差为位置解算值和/或定位测量量的误差，例如：基于1sigma或者3sigma准则的误差值(其中，sigma表示测量量的标准差)；方差值；在[X％]置信水平下，位置解算值和/或定位测量量的误差位于某误差区间的概率等，其中，X取值范围是从0到100，候选取值为80、90和95等。

比如，预先设定参数要求，预设参数要求中包括对至少一个所述定位参考参数的要求；得到定位参考参数后，依据预设参数要求判断该候选参考设备是否满足作为目标参考设备的要求；若满足，则该候选参考设备可以作为目标参考设备；若不满足，则后续继续轮询判断。
情况二，若所述候选参考设备包括至少两个参考设备，则根据预设选择方式，确定所述候选参考设备中的目标参考设备。其中，预设选择方式中，可以包括依据其中一个定位参考参数选择，还可以包括依据其中多个定位参考参数选择，例如采用加权求和的方式。
