下面结合附图对本公开所提供的定位方法及其装置进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种定位方法的流程示意图。该方法被配置为由终端设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤21，向接入网设备发送第一指示信息，其中，第一指示信息用于指示以下至少一项：终端设备的类型，以及，定位参考信号测量信息。
其中，终端设备的类型可以根据终端设备的能力强弱分为低端能力终端设备(Reduced capability UE，RedCap)、及普通终端设备等等，其中，普通终端设备，也可以称为非低端能力终端设备、正常能力终端设备等等，本公开对此不作限定。
通常，低端能力终端设备的接收天线可能只有一根，另外，低端能力终端设备的尺寸比较小，天线辐射效率较低，即使在相同的地理位置，低端能力终端设备发送的信号强度可能会低于正常能力终端设备。因此，本公开中，在定位过程中，终端设备可以通过将其类型和/或定位参考信号测量信息，上报给基站，从而使得网络设备可以根据终端设备的类型，选择合适的定位算法，对终端设备进行定位。
可选的，定位参考信号测量信息可以为终端设备确定的定位参考信号测量值。即定位参考信号测量信息可以为以下至少一项：
定位参考信号强度测量值；
定位参考信号的测量到达时间差。
其中，定位参考信号强度测量值可以为终端设备测量的定位参考信号的接收功率。
其中，定位参考信号的测量到达时间差，可以为终端设备测量的接收到定位参考信号的时刻与定位参考信号的发送时刻之间的时间差。
需要说明的是，若第一指示信息，仅用于指示终端设备的类型，则为了实现定位，终端设备还需要定位参考信号的测量值，比如定位参考信号强度测量值，或者定位参考信号的测量到达时间差等发送给接入网设备。
通过实施本公开实施例，终端设备向接入网设备发送第一指示信息，其中，第一指示信息用于指示以下至少一项：终端设备的类型，以及，定位参考信号测量值。由此，终端设备通过向接入网设备发送其类型、以及定位参考信号测量值，从而使核心网设备可以基于终端设备的类型调整定位算法，对终端设备进行定位，从而实现了对不同类型终端设备的精确定位。
请参见图3，图3是本公开实施例提供的另一种定位方法的流程示意图。该方法被配置为由终端设备执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤31，向接入网设备发送第一指示信息,其中，第一指示信息用于指示定位参考信号测量信息。
可选的，定位参考信号测量信息可以为终端设备根据其类型对定位参考信号测量值修正后的值，即定位参考信号测量信息可以为以下至少一项：修正后的定位参考信号强度值；以及，修正后的定位参考信号的到达时间差。

可选的，终端设备也可以根据终端设备的类型，对定位参考信号的测量到达时间差进行修正，以确定修正后的定位参考信号的到达时间差。
需要说明的是，终端设备的类型不同，定位参考信号强度测量值，或定位参考信号的测量到达时间差对应的修正方式可能也不同。
可选的，终端设备可以基于协议约定，或者与接入网设备及核心网设备协商确定不同类型终端设备对应的修正方式。
举例来说，若终端设备的类型为低端能力终端设备，由于低端能力终端设备的接收天线只有一根，接收天线的辐射效率较低，获取的定位参考信号强度测量值或定位参考信号的测量到达时间差可能存在误差，因此，可以将定位参考信号强度测量值加上一定数值之后作为修正后的定位参考信号强度值，或者，将定位参考信号的测量到达时间差加上一定时间段后作为修正后的定位参考信号的到达时间差。
或者，终端设备的类型若为正常能力终端设备，则不需要对定位参考信号强度测量值进行修正。
可以理解的是，终端设备对定位参考信号强度值，或定位参考信号的测量到达时间差进行修正之后，消除了不同类型的终端设备对定位参考信号的测量误差，由此，核心网设 备即可基于统一的定位算法或定位模型对接收到的修正后的定位参考信号强度值，或修正后的定位参考信号的到达时间差进行处理，以实现对不同类型终端设备的精确定位。
通过实施本公开实施例，终端设备向接入网设备发送第一指示信息，其中，第一指示信息用于指示修正后的定位参考信号测量值。由此，终端设备通过向接入网设备修正后的定位参考信号测量值，从而使核心网设备可以基于修正后的定位参考信号测量值，对终端设备进行定位，从而实现了对不同类型终端设备的精确定位。

可选的，定位参考信号测量信息可以为终端设备确定的定位参考信号测量值，也可以为终端设备根据其类型对定位参考信号测量值修正后的值，即定位参考信号测量信息可以为以下至少一项：

修正后的定位参考信号强度值；以及，
修正后的定位参考信号的到达时间差。
其中，定位参考信号强度测量值可以为终端设备测量的定位参考信号的接收功率。
其中，定位参考信号的测量到达时间可以为终端设备测量的接收到定位参考信号的时刻与定位参考信号的发送时刻之间的时间差。
其中，修正后的定位参考信号强度值为，终端设备根据终端设备的类型，对定位参考信号强度测量值进行修正，确定的修正后的定位参考信号强度值。
其中，修正后的定位参考信号的到达时间差为，终端设备根据终端设备的类型，对定位参考信号的测量到达时间差进行修正，确定的修正后的定位参考信号的到达时间差。
步骤42，向核心网设备发送第二指示信息，其中，第二指示信息为基于第一指示信息生成的。
可选的，第二指示信息用于指示以下至少一项：终端设备的类型，以及，定位参考信号测量信息。
可以理解的是，接入网设备在接收到终端设备发送的第一指示信息之后，可以基于第一指示信息生成第二指示信息，并向核心网设备发送第二指示信息。
可选的，第一指示信息为终端设备的类型，以及定位参考信号测量值，则接入网设备可以根据终端设备的类型对定位参考信号测量值进行修正，以生成第二指示信息，或者， 接入网设备也可以不对定位参考测量值进行修正，直接将第一指示信息作为第二指示信息。
可选的，第一指示信息为修正后的定位参考信号测量值，则接入网设备不需要对第一指示信息进行处理，即可生成第二指示信息，第二指示信息用于指示修正后的定位参考信号测量值。
通过实施本公开实施例，接入网设备接收来自终端设备的第一指示信息，其中，第一指示信息用于指示以下至少一项：终端设备的类型，以及，定位参考信号测量信息，之后向核心网设备发送基于第一指示信息生成的第二指示信息。由此，接入网设备通过向核心网设备发送其类型、或者修正后的定位参考信号测量值，从而使核心网设备可以基于终端设备的类型调整定位算法，或者基于修正后的定位参考信号测量值，对终端设备进行定位，从而实现了对不同类型终端设备的精确定位。

可选的，修正后的定位参考信号测量值可以包括：修正后的定位参考信号强度值，和/或，修正后的定位参考信号的到达时间差。
可以理解的是，由于不同类型的终端设备的能力不同，获取的定位参考信号测量值可能存在不同的误差，因此，接入网设备在接收到终端设备发送的用于指示终端设备的类型，以及定位参考信号测量值之后，可以根据终端设备的类型，对定位参考信号测量值进行修正，以确定修正后的定位参考信号测量值。
可选的，接入网设备可以基于协议约定，或者与终端设备设备及核心网设备协商，确定不同类型终端设备的定位参考信号测量值的修正方式。
可选的，若定位参考信号测量值为定位参考信号强度测量值，接入网设备则根据终端设备的类型，对定位参考信号强度测量值进行修正，以确定修正后的定位参考信号强度值。
可选的，若定位参考信号测量信息为定位参考信号的测量到达时间差，接入网设备则根据终端设备的类型，对定位参考信号的测量到达时间差进行修正，以确定修正后的定位参考信号的到达时间差。举例来说，终端设备的类型为低端能力终端设备，可以将定位参考信号强度测量值加上一定数值之后作为修正后的定位参考信号强度值。其中，一定数值 可以为2dB，3dB等等，本公开对此不作限定。或者，也可以将定位参考信号的测量到达时间差加上一定时间段之后作为修正后的定位参考信号的到达时间差。其中，一定时间段可以为2s，3s等等，本公开对此不作限定。
步骤53，根据修正后的定位参考信号测量值，生成第二指示信息。
可选的，，第二指示信息用于指示终端设备对应的修正后的定位参考信号测量值。步骤54，向核心网设备发送第二指示信息。
其中，步骤54的具体实现形式，可参照本公开中其他各实施例中的详细描述，此处不再详细赘述。
通过实施本公开实施例，接入网设备接收来自终端设备的第一指示信息，之后根据终端设备的类型，对定位参考信号测量值进行修正，以确定修正后的定位参考信号测量值，最后根据修正后的定位参考信号测量值，生成第二指示信息，并向核心网设备发送第二指示信息。由此，接入网设备通过向核心网设备发送修正后的定位参考信号测量值，从而使核心网设备可以基于修正后的定位参考信号测量值，对终端设备进行定位，从而实现了对不同类型终端设备的精确定位。

其中，定位参考信号的测量到达时间可以为终端设备测量的接收到定位参考信号的时刻与定位参考信号的发送时刻之间的时间差。
可选的，修正后的定位参考信号强度值，可以为终端设备根据终端设备的类型，对定位参考信号强度测量值进行修正，确定的修正后的定位参考信号强度值。或者也可以为接入网设备根据终端设备的类型，对定位参考信号强度测量值进行修正，确定的修正后的定位参考信号强度值。

可以理解的是，终端设备的类型不同，对应的定位算法也不同。
