一种定位方法、装置、终端、网络设备及介质
相关申请的交叉引用
本申请主张在2022年11月03日在中国提交的中国专利申请No.202211368671.4的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,特别是指一种定位方法、装置、终端、网络设备及介质。
背景技术
在未来通信场景中,可通过移动通信网络节点(包括卫星、热气球、飞行器或空间站等非地面通信网络(Non-terrestrial network,NTN)中的非地面通信网络节点或部署于公交、地铁等地面通信网络节点)对数据进行分发/转发。以NTN为例,如图1和图2所示,非地面通信网络节点与网关通过馈线链路(feeder link)相连,非地面通信网络节点与用户设备通过服务链路(service link)相连。随着非地面通信网络节点移动,服务链路(非地面通信网络节点与用户设备(User Equipment,UE)间链路)会发生变更,这对于UE来说,需要进行物理小区标识(Physical Cell Identifier,PCI)变更。NTN中,小区分为固定小区(如伪地球固定小区(Quasi-earth-fixed cell))和移动小区(moving cell case),其中,移动小区为随着卫星移动而移动的小区,小区垂直于地面;固定小区为在某一时间段内服务固定地理区域的卫星下的小区,该时间段内小区的中心位置不变。
目前网络无法直接获取UE的位置信息,即使可以获取UE基于全球导航卫星系统(Global Navigation Satellite System,GNSS)的位置信息,网络认为终端所上报的位置信息可能不精确或存在虚假可能,需要基于无线网络进一步验证终端位置,如对至少对终端进行粗粒度的定位。
而现有的定位流程依赖于非接入层(Non-access stratum,NAS),所有流程都需要通过与位置管理服务(Location Management Function,LMF)的多 轮交互进行统筹确认。对于NTN场景下,多轮NAS信令的传输需要耗费大量时间,且由于卫星单一波束(小区)覆盖面积大,即使已经不是服务质量最好的小区终端仍能检测到还不错的质量,此外,由于卫星是移动的,传统固定三个基站得到位置的方案并不能解决位置验证的问题,另外卫星的移动性也需要减少配置过程带来的影响、更快得到定位结果。

如果定位配置携带有指示该定位配置类型为终端位置验证时,可使该定 位配置生效,可选地,该定位配置可以在第一时间段内持续生效,终端在第一时间段内始终按照该定位配置执行定位流程,这样可保证即使终端切换到了不同的小区,仍不释放原有的定位相关配置,避免了重复配置流程带来的时延和信令开销。

4、如若定位配置类型为终端位置验证,不释放定位相关配置,即使终端处于切换/重选/重建等流程中。这样可保证终端即使切换到了不同的小区,不释放原有定位相关配置,避免重复配置流程带来的时延和信令开销。
5、网络设备根据预先配置列表(例如,服务网络节点的临近网络节点或 根据星历图/公交时刻表/高速公路/高铁等),进行配置。

6、终端上报时间差(如终端所预估发信号到卫星的时间/终端所预估信号到基站的时间等);
7、网络设备不释放相应配置,测量终端的上行参考信号和/或接收时间差,并进行根据时间戳/服务小区ID等辅助信息和信号质量,计算终端位置。
8、第二网络设备给第一网络设备上报参考信号测量结果,具体可以为终端位置(例如可以为虚拟区域ID、绝对位置、在预设位置的指示),测量结果(包括时间戳和/或PCI,该时间戳为测量结果所对应时间),和/或时间差(终端所预估发信号到卫星的时间/UE所预估信号到基站的时间等);其中,第一网络设备为LMF,第二网络节点为基站。具体位置计算方式可以为:利 用多个所接收SRS中的时间戳1、测量到SRS的时间戳2、已知时间戳2所对应的卫星位置等来计算。
9、网络设备基于位置结果更新TA。
下面以移动小区场景为例对上行定位流程进行说明。
NTN的移动小区场景中,单一卫星,(非)服务小区不更新定位配置,上行(Uplink,UL)-TDOA定位方法

5、卫星1上的服务小区(PCI1)根据配置测量终端发送的SRS。
6、T3时刻,终端切换到卫星1承载的其他小区(PCI2),不释放标识为终端位置验证的定位相关配置(可基于基站内部实现)。
7、T3时刻,网络不释放相应配置,PCI2基于原有配置测量终端发送的SRS和/或时间差。基站结合3个时刻的测量(测量结果与SRS所携带的时间戳和PCI绑定)与测量到SRS的时间戳与相应的卫星本身位置信息,计算到两条双曲线,双曲线的焦点即为终端位置。
其中,本公开实施例中,卫星波束和小区的对应关系有两种可能,一种是波束和小区一一对应,此时一个卫星下的多个波束分别对应各自的小区,但由于同属于同一个卫星,关于UE位置验证的相关配置参数可以保持(网络侧控制是否保持);另一种是波束和小区为多对一的情况,此时一个卫星下的某几个波束对应同一个PCI,因此对应同一PCI的波束覆盖小区在终端看来即使波束更换,PCI也没有变换,即终端感受不到小区变换,则不会释放关于终端验证的相关配置参数。如果变换了PCI但还同属于同一个卫星,则同样的由网络侧控制是否可以保持关于终端验证的相关配置参数。其中,网络设备关于定位的相关配置可参考下表:

该实施例的定位方法中,终端接收定位配置,当定位配置指示终端位置验证时定位配置生效,终端可按照定位配置执行定位流程,这样在对于NTN场景,可利用在移动的同一个卫星或固定小区场景中同PCI对应的不同卫星,分时段对终端进行定位相关配置与定位参考信号测量,得到UE的位置,更节约信令开销、降低时延。
