在本公开实施例中，终端设备或网络侧设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本公开实施例并未对本公开实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本公开实施例的提供的方法的代码的程序，以根据本公开实施例提供的方法进行通信即可，例如，本公开实施例提供的方法的执行主体可以是终端设备或网络侧设备，或者，是终端设备或网络侧设备中能够调用程序并执行程序的功能模块。
请参见图1，为本公开适用的一种可能的通信系统10的结构图。
如图1所示，通信系统10包括终端设备101、网络侧设备102以及位置管理功能设备103，下面分别进行说明：
1、终端设备(terminal device，TD)101：简称为终端，是一种具有无线收发功能的设备，可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的终端，移动台(mobile station，MS)，终端(terminal)，用户设备(user equipment，UE)，软终端等等。终端可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。例如，手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
2、(无线)网络侧设备(radio access network，(R)AN)102：是一种为终端提供无线通信功能的设备，包括但不限于：5G中的下一代基站(g nodeB，gNB)、演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(baseBand unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)等。
3、位置管理功能设备103：或称为位置管理网元，用于进行终端设备101的位置管理，例如，确定UE的位置信息。具体来说，第五代(the 5th generation，5G)无线通信系统中的位置管理功能设备可以是LMF(location management function，LMF)设备，LMF设备可以根据核心网实体(如接入和移动管理功能实体(access and mobility management function，AMF))的请求确定UE的位置信息，并将 UE的位置信息提供给AMF，从而提供定位服务(location services，LCS)。在实施中，AMF可以向UE分配至少一个LMF，用于向UE提供定位服务，UE在需要获取定位信息时，可以通过AMF向LMF请求位置信息。在未来通信(例如6G或者其他的网络中)，位置管理网元仍可以是LMF网元，或有其它的名称，本公开不做限定。
需要说明的是，本公开实施例中所涉及的功能设备还可以称为网元或功能或功能实体，例如，位置管理功能设备还可以称为位置管理功能或者位置管理功能实体或者位置管理网元。各个功能设备的名称在本公开中不做限定，本领域技术人员可以将上述功能设备的名称更换为其它名称而执行相同的功能，均属于本公开保护的范围
可以理解的是，上述功能设备既可以是硬件设备中的网络元件，也可以是在专用硬件上运行软件功能，或者是平台(例如，云平台)上实例化的虚拟化功能。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本公开所提供的定位方法和装置进行详细地介绍。
请参见图2，为本公开实施例提供的一种定位方法的流程图。
如图2所示，该方法由终端设备执行，包括但不限于如下步骤：
S1：接收预配置的第一定位辅助信息。
在5G(The 5th Generation，未来第五代)的NR(New Radio，新空口)系统中，引入了多种定位技术，以对终端设备进行定位。
其中，在一些定位技术中，终端设备接收预配置的第一定位辅助信息，当需要对终端设备进行定位的情况下，则不再需要接收定位辅助信息，终端设备可以直接使用预配置的第一定位辅助信息。
可以理解的是，终端设备接收预配置的第一定位辅助信息可以采用多种方式，例如：接收LMF设备通过长期演进定位协议(long term evolution positioning protocol，LPP)消息发送的第一定位辅助信息；或者接收网络侧设备广播发送的LMF设备提供的第一定位辅助信息。
S2：确定第一定位辅助信息是否可用。
其中，预配置的第一定位辅助信息包含时效性指示，具有时效性，例如：在特定区域或者特定时间段内有效。
可以理解的是，终端设备的第一定位辅助信息是预先进行配置的，例如是在T1时刻进行预配置的，而在对终端设备定位时，终端设备使用第一定位辅助信息是在T2时刻进行的，T1时刻和T2时刻之间存在时间差，这就可能会造成预配置的第一定位辅助信息在对终端设备进行定位时已经失效，从而会造成对终端设备定位不准确。
本公开实施例中，对第一定位辅助信息是否可用进行识别，具体的，可以通过检测终端设备是否超出第一定位辅助信息时效性的特定区域，或者判断使用第一定位辅助信息的时间是否超出第一定位辅助信息时效性的特定时间段，或者终端设备无法根据第一定位辅助信息测量定位参考信号PRS(position reference single，PRS)等等。
需要说明的是，上述方式仅作为示意，旨在为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，此处并未进行对确定第一定位辅助信息是否可用的方式进 行一一列举，本领域技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。

在一些实施例中，本公开实施例中，第一定位辅助信息不可用，包括：在接收到触发终端设备使用第一定位辅助信息的消息的情况下，终端设备根据第一定位辅助信息不能够测量定位参考信号PRS(positioning reference signal，PRS)。
示例性实施例中，终端设备接收到位置信息请求(location information request)消息，终端设备无法根据第一定位辅助信息测量定位参考信号PRS，此时，说明预配置的第一定位辅助信息不可用。

请参见图3，为本公开实施例提供的另一种定位方法的流程图。
如图3所示，该方法由终端设备执行，包括但不限于如下步骤：
S11：接收预配置的第一定位辅助信息。
其中，S11与上述实施例中S1存在相同或相近的技术效果，对S11方法的具体实施方式的描述，可以参见上述实施例中S1的具体实施方式的描述，此处不再赘述。
S12：在第一定位辅助信息存在时效性的情况下，确定第一定位辅助信息是否失效。
具体的，第一定位辅助信息存在时效性，可以为第一定位辅助信息在特定区域和/或特定时间段内有效。
可以理解的是，预配置的第一定位辅助信息在特定区域内有效，不同小区的预配置的第一定位辅助信息可能不同，终端设备在某一小区时，预配置的第一定位辅助信息有效，而当终端设备从一个小区移动至另一个小区时，第一定位辅助信息可能已经失效。第一定位辅助信息在特定时间段内有效，预配置的第一定位辅助信息可能预先设置了在特定时间段内有效，在超出了该特定时间段后，预配置的第一定位辅助信息可能已经失效。
在第一定位辅助信息存在时效性为第一定位辅助信息在特定区域和/或特定时间段内有效的情况下，对终端设备所在的位置和/或对终端设备进行定位的时间与预配置第一定位辅助信息的时间进行检测，可以确定第一定位辅助信息是否失效。
需要说明的是，第一定位辅助信息的时效性不仅仅是在特定区域和/或特定时间段内有效，还可以 是在满足其他条件的情况下有效，可以根据需要进行设置，本公开对此不作具体限制。
S13：在第一定位辅助信息未失效的情况下，使用第一定位辅助信息。
具体的，第一定位辅助信息未失效，可以为终端设备进行定位时使用该第一定位辅助信息未超出特定区域和/或终端设备使用该第一定位辅助信息的时间与预配置该第一定位辅助信息的时间二者之间的时间差未超出特定时间段。
基于此，第一定位辅助信息未失效的情况下，在对终端设备进行定位时，可以直接使用第一定位辅助信息，能够准确的对终端设备进行定位。S14：在第一定位辅助信息失效的情况下，向LMF设备发送定位辅助信息请求消息。
具体的，第一定位辅助信息失效，可以为终端设备进行定位时使用该第一定位辅助信息已超出特定区域和/或终端设备使用该第一定位辅助信息的时间与预配置该第一定位辅助信息的时间二者之间的时间差已超出特定时间段。
本公开实施例中，在第一定位辅助信息存在时效性的情况下，确定第一定位辅助信息失效，从而可以确定第一定位辅助信息不可用。基于此，终端设备向LMF设备发送定位辅助信息请求消息，
本公开实施例中，在第一定位辅助信息存在时效性，确定第一定位辅助信息失效，第一定位辅助信息不可用的情况下，向位置管理功能LMF设备发送定位辅助信息请求消息，例如：通过发送长期演进定位协议(long term evolution positioning protocol，LPP)请求辅助数据(request assistance data)，请求LMF设备向终端设备重新配置定位辅助信息，从而能够实现在对终端设备进行定位时，不再使用预配置的第一定位辅助信息，而应用终端设备请求的重新配置的定位辅助信息，以避免对终端设备定位不准确的问题。
其中，本公开实施例中LMF设备向终端设备重新配置定位辅助信息，可以通过长期演进定位协议LPP消息向终端设备重新配置定位辅助信息，或者，向网络侧设备重新提供定位辅助信息，通过网络侧设备广播向终端设备重新配置定位辅助信息等方式实现。
示例性实施例中，本公开实施例中，在第一定位辅助信息存在时效性，确定第一定位辅助信息失效，第一定位辅助信息不可用的情况下，终端设备可以等待网络侧设备发送触发其使用预配置的第一定位辅助信息的指示，在接收到网络侧设备发送的触发其使用预配置的第一定位辅助信息的指示的情况下，再执行相应的步骤，具体可参见本公开上述一些实施例中的步骤，此处不再赘述。
请参见图4，为本公开实施例提供的又一种定位方法的流程图。
如图4所示，该方法由终端设备执行，包括但不限于如下步骤：
S111：接收预配置的第一定位辅助信息。
其中，S111与上述实施例中S1和S11存在相同或相近的技术效果，对S111方法的具体实施方式的描述，可以参见上述实施例中S1和S11的具体实施方式的描述，此处不再赘述。
S112：在接收到触发终端设备使用第一定位辅助信息的消息的情况下，确定网络侧设备是否发送了应用当前定位技术所需要的第二定位辅助信息。
示例性实施例中，终端设备接收到触发其使用网络通过LPP消息配置的第一定位辅助信息的消息，例如：终端设备接收到位置信息请求(location information request)消息，确定网络侧设备是否发送了应用当前定位技术所需要的第二定位辅助信息，例如：确定基站是否广播了NR DL-TDOA/DL-AoD  Assistance Data消息，即posSibType6-1，posSibType6-2，或posSibType6-3消息。
S113：在网络侧设备发送了第二定位辅助信息的情况下，确定第一定位辅助信息和第二定位辅助信息是否一致。
在基站发送了应用当前定位技术所需要的第二定位辅助信息的情况下，确定第一定位辅助信息和第二定位辅助信息是否一致。
可以理解的是，第一定位辅助信息和第二定位辅助信息一致的情况下，说明预配置的第一定位辅助信息能够应用于当前的定位技术，能够准确的对终端设备进行定位，获得较为准确的终端设备位置；但是，若第一定位辅助信息与第二定位辅助信息不一致，则说明预配置的第一定位辅助信息不适用于当前的定位技术，使用第一定位辅助信息可能无法获得较为准确的终端设备位置。
S114：在第一定位辅助信息和第二定位辅助信息一致的情况下，使用第一定位辅助信息或者第二定位辅助信息。
本公开实施例中，在第一定位辅助信息与第二定位辅助信息一致的情况下，可以直接使用第一定位辅助信息或者第二定位辅助信息，能够应用于当前的定位技术，也即能够满足当前定位技术的需求，从而能够准确的对终端设备进行定位，获得较为准确的终端设备位置。
请再次参见图4，在一些实施例中，本公开实施例中提供的定位方法，还包括：S115：在第一定位辅助信息和第二定位辅助信息不一致的情况下，使用第二定位辅助信息。
本公开实施例中，在第一定位辅助信息与第二定位辅助信息不一致的情况下，使用第二定位辅助信息，应用于当前的定位技术，能够满足当前定位技术的需求，从而能够准确的对终端设备进行定位，获得较为准确的终端设备位置。
在一些实施例中，在第一定位辅助信息和第二定位辅助信息不一致的情况下，向LMF设备发送定位辅助信息请求消息。
本公开实施例中，在第一定位辅助信息和第二定位辅助信息不一致的情况下，确定第一定位辅助信息不可用，向位置管理功能LMF设备发送定位辅助信息请求消息，例如：通过发送长期演进定位协议LPP请求辅助数据(request assistance data)，请求LMF设备向终端设备重新配置定位辅助信息，从而能够实现在对终端设备进行定位时，不再使用预配置的第一定位辅助信息，而应用重新配置的定位辅助信息，以避免对终端设备定位不准确的问题。
在一些实施例中，本公开实施例中LMF设备向终端设备重新配置定位辅助信息，可以通过长期演进定位协议LPP消息向终端设备重新配置定位辅助信息，或者，向网络侧设备重新提供定位辅助信息，通过网络侧设备广播向终端设备重新配置定位辅助信息等方式实现。
在一些实施例中，接收预配置的第一定位辅助信息，包括：接收LMF设备通过长期演进定位协议LPP消息发送的第一定位辅助信息；或者接收网络侧设备通过定位系统消息发送的LMF设备提供的第一定位辅助信息。
其中，LMF设备通过长期演进定位协议LPP消息发送的第一定位辅助信息，示例性的，网络侧设备透传LMF设备发送给终端设备的第一定位辅助信息，网络侧设备可以为基站。
接收网络侧设备发送的LMF设备提供的第一定位辅助信息，示例性的，LMF设备向网络侧设备提供定位辅助信息，网络侧设备通过广播的方式发送给终端设备，网络侧设备可以为基站。
需要说明的是，本公开实施例中，在网络侧设备发送了应用当前定位技术所需要的第二定位辅助信 息的情况下，终端设备接收预配置的第一定位辅助信息，会同时存在第一定位辅助信息和第二定位辅助信息，在此情况下，对于第一定位辅助信息和第二定位辅助信息的发送方式，并不能一致，可以理解的是，在第一定位辅助信息是通过LMF设备通过长期演进定位协议LPP消息发送的情况下，第二定位辅助信息则是网络侧设备发送的LMF设备提供的第二定位辅助信息；在第一定位辅助信息是通过网络侧设备发送的LMF设备提供的第一定位辅助信息的情况下，第二定位辅助信息则是通过LMF设备通过长期演进定位协议LPP消息发送的。
通过实施本公开实施例，可以在对终端设备进行定位时，预先对预配置的第一定位辅助信息是否可用进行判断，从而在第一定位辅助信息可用的情况下，使用第一定位辅助信息对终端设备进行定位。通过这种方式，可以避免由于第一定位辅助信息失效造成对终端设备定位不准确，从而获得较为准确的终端设备位置。
在一些实施例中，终端设备接收预配置的第一定位辅助信息，也可能接收网络侧设备发送的应用当前定位技术所需要的第二定位辅助信息。
其中，第一定位辅助信息可以是LMF设备通过长期演进定位协议LPP消息发送给终端设备的信息，而第二定位辅助信息是LMF设备向网络侧设备提供，网络侧设备通过定位系统消息广播发送给终端设备的信息。或者，第一定位辅助信息可以是LMF设备向网络侧设备提供，网络侧设备通过广播发送给终端设备的信息，第二定位辅助信息是LMF设备通过长期演进定位协议LPP消息发送给终端设备的信息。
示例性实施例中，本公开实施例中，终端设备接收预配置的第一定位辅助信息是LMF设备通过长期演进定位协议LPP消息发送给终端设备的信息，以下简称LPP消息，以及接收到在对终端设备进行定位时，网络侧设备发送的应用当前定位技术所需要的第二定位辅助信息是LMF设备向网络侧设备提供，网络侧设备通过定位系统消息广播发送给终端设备的信息，以下简称系统消息，此时，终端设备接收到LPP消息和系统消息，在此情况下，需要对LPP消息和系统消息进行判断，以确定终端设备使用LPP消息还是系统消息。
判断LPP消息和系统消息是否一致，以确定LPP消息是否可用，以确定终端设备使用LPP消息还是使用系统消息。其中，在LPP消息和系统消息一致的情况下，终端设备使用LPP消息或者系统消息。在LPP消息和系统消息不一致的情况下，终端设备使用系统消息。在LPP消息和系统消息不一致的情况下，向LMF设备发送定位辅助信息请求消息。
示例性实施例中，本公开实施例中，终端设备接收预配置的第一定位辅助信息是LMF设备向网络侧设备提供，网络侧设备通过定位系统消息广播发送给终端设备的信息，以下简称系统消息，以及接收到在对终端设备进行定位时，网络侧设备发送的应用当前定位技术所需要的第二定位辅助信息是LMF设备通过长期演进定位协议LPP消息发送给终端设备的信息，以下简称LPP消息，此时，终端设备接收到系统消息和LPP消息，在此情况下，需要对系统消息和LPP消息进行判断，以确定终端设备使用系统消息还是LPP消息。
