Description

一种有效信息指示方法、装置、用户设备、网络侧设备及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种有效信息指示方法、装置、用户设备、网络侧设备及存储介质。
背景技术
通信系统中，为了降低定位时延，在UE(User Equipment，用户设备)进行定位前，网络侧设备会给UE预配置定位辅助信息，以便当需要对UE定位时，UE能够直接使用网络侧设备之前预配置的定位辅助信息，提高定位效率。其中，预配置的定位辅助信息包括有PRS(Position Reference Signal，定位参考信号)资源的测量优先级信息和参考PRS资源，该PRS资源的测量优先级信息具体和各个PRS资源对应的TRP(transmission-reception point，发送接收点)与UE之间的距离远近相关，其中，距离UE越近的TRP对应的PRS资源的优先级越高，以及，UE可以基于PRS资源的测量优先级信息和参考PRS资源进行PRS测量以实现定位。
但是，相关技术中，网络侧设备给UE预配置定位辅助信息的时间点与UE使用预配置的定位辅助信息进行定位的时间点之间可能存在较大的时间间隔，在该时间间隔内，UE极有可能会发生移动，则会使得UE与各个TRP的距离发生了变化，进而使得预配置的定位辅助信息中的PRS资源的优先级信息和参考PRS资源不再适用于移动后的UE，此时若仍然基于预配置的定位辅助信息对UE进行定位，则会影响定位精度。因此，亟需一种方法以解决预配置的定位辅助信息的有效性的问题。

下面参考附图对本公开实施例所提供的有效信息指示方法、装置、用户设备、网络侧设备及存储介质进行详细描述。
图1为本公开实施例所提供的一种有效信息指示方法的流程示意图，该方法由网络侧设备执行，如图1所示，该上报方法可以包括以下步骤：
步骤101、向UE发送位置信息请求(location information request)消息，位置信息请求消息包括定位辅助信息的有效信息。
在本公开的一个实施例之中，UE可以是指向用户提供语音和/或数据连通性的设备。UE可以经RAN(Radio Access Network，无线接入网)与一个或多个核心网进行通信，UE可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、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、远程终端(remoteterminal)、接入终端(access terminal)、用户装置(user terminal)或用户代理(useragent)。或者，UE也可以是无人飞行器的设备。或者，UE也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线终端。或者，UE也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
在本公开的一个实施例之中，有效信息可以包括定位辅助信息中PRS资源的测量优先级信息、参考PRS资源的信息、定位辅助信息的有效区域信息中的至少一种。
需要说明的是，在本公开的一个实施例之中，网络侧设备可以给UE配置多个PRS资源，每一PRS资源对应一TRP，PRS资源用于指示TRP传输PRS信号的方式，以使得TRP能够基于对应的PRS资源来传输对应的PRS信号。
在本公开的一个实施例之中，上述PRS资源的测量优先级信息具体和各个PRS资源对应的TRP与UE之间的距离远近相关，其中，距离UE越近的TRP对应的PRS资源的优先级越高，距离UE越远的TRP对应的PRS资源的优先级越低。
在本公开的一个实施例之中，PRS资源的测量优先级信息可以包括以下的至少一种：
PRS资源标识列表，PRS资源标识列表包括：基于PRS资源的测量优先级进行升序或降序排列后的PRS资源对应的PRS资源标识；
PRS资源对应的PCI(Physical cell ID，物理小区标识)列表，PCI列表包括：基于PRS资源的测量优先级进行升序或降序排列后的PRS资源对应的PCI；
PRS资源对应的CGI(Cell global ID，全球小区标识)列表，CGI列表包括：基于PRS资源的测量优先级进行升序或降序排列后的PRS资源对应的CGI。
也即是，在本公开的一个实施例之中，可以利用上述的PRS资源标识列表，和\或，PRS资源对应的PCI列表，和\或，PRS资源对应的CGI列表的形式来指示PRS资源的测量优先级信息。其中，需要说明的是，在本公开的一个实施例之中，PRS资源标识列表，和\或，PRS的PCI列表，和\或，PRS的CGI列表中可以包括给UE配置的所有PRS资源。在本公开的另一个实施例之中，PRS资源标识列表，和\或，PRS的PCI列表，和\或，PRS的CGI列表可以仅包括优先级较高的前N个PRS资源，其中，N为正整数，N小于给UE配置的所有PRS资源。
其中，在本公开的一个实施例之中，若PRS资源的测量优先级信息包括PRS资源标识列表，则在本公开的一个实施例之中，该PRS资源标识列表可以包括：基于PRS资源的测量优先级进行升序排列后的PRS资源对应的PRS资源标识。其中，表1为本公开实施例提供的一种按照升序排列的PRS资源标识列表。
表1
PRS资源#2的PRS资源标识
PRS资源#1的PRS资源标识
PRS资源#3的PRS资源标识
示例的，在本公开的一个实施例之中，假设网络侧设备为UE配置了三个PRS资源，分别为PRS资源#1、PRS资源#2、PRS资源#3，其中，PRS资源#1对应有TRP#1、PRS资源#2对应有TRP#2、PRS资源#3对应有TRP#3，以及，TRP#2与UE之间的距离小于TRP#1与UE之间的距离且小于TRP#3与UE之间的距离，由此可知，PRS资源#1、PRS资源#2、PRS资源#3的优先级顺序为：PRS资源#2的优先级高于PRS资源#1的优先级且高于PRS资源#3的优先级。此时，可以采用上述表1来指示PRS资源的测量优先级信息。
进一步地，在本公开的一个实施例之中，上述参考PRS资源具体可以为UE对应的多个PRS资源中的任一个PRS资源，以及，在本公开的一个实施例之中，该参考PRS资源具体作用为：UE基于参考PRS资源的接收时刻与除参考PRS资源之外的各个其他PRS资源的接收时刻之间的时间差，来确定PRS的到达时间差(Timing difference of Arrival,TDOA)。
示例的，假设网络侧设备为UE配置了三个PRS资源，分别为PRS资源#1、PRS资源#2、PRS资源#3，将PRS资源#3确定为参考PRS资源，则UE可以基于PRS资源#3的接收时刻与PRS资源#2的接收时刻之间的时间差、PRS资源#3的接收时刻与PRS资源#1的接收时刻之间的时间差来对UE进行定位。
以及，在本公开的一个实施例之中，上述参考PRS资源的信息可以包括以下的至少一种：
参考PRS资源对应的PRS资源标识；
参考PRS资源对应的PCI；
参考PRS资源对应的CGI。
也即是，在本公开的一个实施例之中，可以利用上述的参考PRS资源对应的PRS资源标识，和\或，参考PRS资源对应的PCI，和\或，参考PRS资源对应的CGI来指示参考PRS资源。
再进一步地，在本公开的一个实施例之中，上述定位辅助信息的有效区域信息可以包括以下的至少一种：
定位辅助信息的有效区域信息由PCI列表构成；
定位辅助信息的有效区域信息由CGI列表构成。
定位辅助信息的有效区域信息由TRPID列表构成。
也即是，在本公开的一个实施例之中，可以利用上述的定位辅助信息的有效区域信息中所包括的各个小区的PCI列表，和\或，定位辅助信息的有效区域中所包括的各个小区的CGI列表，和/或，定位辅助信息的有效区域中所包括的各个TRP的TRP ID列表来指示UE能够使用预配置的定位辅助信息的有效区域。
基于此，在本公开的一个实施例之中，假设定位辅助信息的有效区域信息包括有PCI#1和PCI#2，则说明当UE处于PCI#1对应的小区和PCI#2对应的小区时，定位辅助信息是有效的，UE可以基于该定位辅助信息进行定位。
此外，需要说明的是，在本公开的一个实施例之中，上述的位置信息请求消息中所包括的PRS资源的测量优先级信息、参考PRS资源的信息、定位辅助信息的有效区域信息具体是网络侧设备向UE发送位置信息请求消息这一时间点下UE对应的PRS资源的测量优先级信息、参考PRS资源的信息、定位辅助信息的有效区域信息。
具体的，在本公开的一个实施例之中，上述有效信息中的PRS资源的测量优先级信息主要是基于网络侧设备向UE发送位置信息请求消息这一时间点下各个TRP与UE之间的距离确定的。
综上所述，在本公开实施例提供的有效信息指示方法之中，网络侧设备会向UE发送位置信息请求消息，该位置信息请求消息包括定位辅助信息的有效信息，该有效信息包括定位辅助信息中PRS资源的测量优先级信息、参考PRS资源的信息、定位辅助信息的有效区域信息中的至少一种。由此，当UE基于网络侧设备发送的位置信息请求消息触发定位时，可以基于该位置信息请求消息中的有效信息进行有效且精确的PRS测量来实现定位，则确保了定位精度。
图2为本公开实施例所提供的一种有效信息指示方法的流程示意图，该方法由网络侧设备执行，如 图2所示，该上报方法可以包括以下步骤：
步骤201、向UE预配置定位辅助信息。
在本公开的一个实施例之中，向UE预配置定位辅助信息的方法可以包括以下至少一种：
当网络侧设备接收到延迟位置服务请求时，向UE预配置定位辅助信息；
网络侧设备为连接态下的UE预配置定位辅助信息，预配置的定位辅助信息应用于连接态和/或非连接态下的UE；
当网络侧设备接收到scheduled location time(预定位置时间)信息时，向UE预配置定位辅助信息。
其中，在本公开一个实施例之中，网络侧设备向UE预配置的定位辅助信息可以包括有PRS资源的测量优先级信息和参考PRS资源的信息。
以及，需要说明的是，在本公开的一个实施例之中，上述的预配置的定位辅助信息中的PRS资源的测量优先级信息具体是基于网络侧设备向UE预配置定位辅助信息这一时间点下各个TRP与UE之间的距离确定的。
此外，在本公开的一个实施例之中，上述网络侧设备可以为LMF(Location Management Function，定位管理功能)。以及，网络侧设备向UE预配置定位辅助信息的方式可以为：LMF将定位辅助信息发送至基站，由基站将LMF发送的定位辅助信息透传至UE。
步骤202、向UE发送位置信息请求消息，位置信息请求消息包括定位辅助信息的有效信息，有效信息包括定位辅助信息中定位参考信号PRS资源的测量优先级信息、参考PRS资源的信息、定位辅助信息的有效区域信息中的至少一种。
其中，关于有效信息的相关介绍可以参考上述实施例描述，本公开实施例在此不做赘述。
以及，在本公开的一个实施例之中，位置信息请求消息中所涉及到的PRS资源应当均是包括于预配置的定位辅助信息中的PRS资源。
以及，需要说明的是，在本公开的一个实施例之中，网络侧设备向UE发送位置信息请求消息是在网络侧设备向UE预配置定位辅助信息之后执行的，也即是，网络侧设备向UE发送位置信息请求消息的第一时间点位于网络侧设备向UE预配置定位辅助信息的第二时间点之后。其中，需要强调的是，在该第一时间点与第二时间点的时间间隔中UE可能会发生移动。若UE发生移动，则会导致UE距离各个TRP的距离发生变化，从而会使得第一时间点下的各个PRS资源的测量优先级信息不同于第二时间点下的各个PRS资源的测量优先级信息。因此，在本公开的一个实施例之中，位置信息请求消息中的PRS资源的测量优先级信息会不同于预配置的定位辅助信息中的PRS资源的测量优先级信息。
示例的，在本公开的一个实施例之中，假设网络侧设备为UE配置了三个PRS资源，分别为PRS资源#1、PRS资源#2、PRS资源#3，其中，PRS资源#1对应有TRP#1、PRS资源#2对应有TRP#2、PRS资源#3对应有TRP#3，其中，在UE向网络侧设备预配置定位辅助信息时，TRP#1与UE之间的距离小于TRP#2与UE之间的距离且小于TRP#3与UE之间的距离，则预配置的定位辅助信息中的PRS资源的测量优先级信息可以为：PRS资源#1的优先级高于PRS资源#2的优先级且高于PRS资源#3的优先级。
以及，在本公开的一个实施例之中，假设网络侧设备向UE预配置定位辅助信息之后，UE发生了移动，且当网络侧设备向UE发送位置信息请求消息时，TRP#2与UE之间的距离小于TRP#1与UE之间的距离且小于TRP#3与UE之间的距离，则网络侧设备向UE发送的位置信息请求消息中的PRS资源的测量优先级信息可以为：PRS资源#2的优先级高于PRS资源#1的优先级且高于PRS资源#3的优先级。
则由上述内容可知，在本公开的一个实施例之中，位置信息请求消息中的PRS资源的测量优先级信息应当是网络侧设备发送位置信息请求消息的第一时间点下适用于UE定位的有效信息。基于此，在本公开的一个实施例之中，即使在第一时间点和第二时间点的时间间隔内UE发生了移动，但是，在后续UE基于网络侧设备发送的位置信息请求消息触发定位时，由于UE是基于位置信息请求消息中包括的适用于当前时刻(即第一时间点)的有效信息进行定位的，而并非是基于预配置的定位辅助信息进行定位的，从而能够实现有效且精确的PRS测量来实现定位，避免出现“由于UE发生移动而导致预配 置的定位辅助信息不适用于移动后的UE的定位测量而影响定位精度”这一情况的发生，则确保了定位精度。
此外，需要说明的是，若网络侧设备检测到UE在第一时间点与第二时间点之间未发生移动，则在本公开的一个实施例之中，网络侧设备向UE发送的位置信息请求消息中的PRS资源的测量优先级信息和参考PRS资源的信息可以与网络侧设备向UE预配置的定位辅助信息中的PRS资源的测量优先级信息和参考PRS资源的信息相同。在本公开的另一个实施例之中，网络侧设备向UE发送的位置信息请求消息中可以不包括PRS资源的测量优先级信息和参考PRS资源的信息，此时，UE可直接基于上述步骤201中网络侧设备预配置的定位辅助信息进行定位。
综上所述，在本公开实施例提供的有效信息指示方法之中，网络侧设备会向UE发送位置信息请求消息，该位置信息请求消息包括定位辅助信息的有效信息，该有效信息包括定位辅助信息中PRS资源的测量优先级信息、参考PRS资源的信息、定位辅助信息的有效区域信息中的至少一种。由此，当UE基于网络侧设备发送的位置信息请求消息触发定位时，可以基于该位置信息请求消息中的有效信息进行有效且精确的PRS测量来实现定位，则确保了定位精度。

方法一：基于UE当前所处小区确定PRS资源的测量优先级信息，和/或，参考PRS资源的信息；
方法二：基于UE的运动信息、以及网络侧设备发送位置信息请求消息时的第一时间点与网络侧设备为UE预配置定位辅助信息时的第二时间点之间的时间差确定PRS资源的测量优先级信息，和/或，参考PRS资源的信息。
其中，在本公开的一个实施例之中，上述方法一中确定PRS资源的测量优先级信息的方法可以包括：使得与UE当前所处小区距离越近的TRP对应的PRS资源的优先级越高。
在本公开的一个实施例之中，上述方法二中确定PRS资源的测量优先级信息的方法可以包括：
先确定出网络侧设备向UE预配置定位辅助信息时UE所处的第一位置，再基于第一时间点和第二时间点之间的时间差和UE的运动信息(例如运动方法、运动速度等)确定出UE的运动轨迹，最后，以第一位置为起点按照运动轨迹确定出网络侧设备发送位置信息请求时的UE所处的第二位置，并使得与第二位置距离越近的TRP对应的PRS资源的优先级越高。
步骤302、向UE发送位置信息请求消息，位置信息请求消息包括定位辅助信息的有效信息，有效信息包括定位辅助信息中定位参考信号PRS资源的测量优先级信息、参考PRS资源的信息、定位辅助信息的有效区域信息中的至少一种。

进一步地，在本公开的一个实施例之中，上述参考PRS资源具体可以为UE对应的多个PRS资源中的任一个PRS资源，以及，在本公开的一个实施例之中，该参考PRS资源具体作用为：UE基于参考PRS资源的接收时刻与除参考PRS资源之外的各个其他PRS资源的接收时刻之间的时间差，来对UE进行定位。
以及，在本公开的一个实施例之中，上述参考PRS资源的信息可以包括以下的至少一种：
