请参见图2，图2是本公开实施例提供的一种校验位置信息的方法的流程示意图，该方法由接入网设备执行。如图2所示，该方法可以包括但不限于如下步骤：

步骤203，基于参考位置信息，对上报的位置信息进行校验。
可以理解的是，终端设备上报的位置信息应当与核心网设备确定的其参考位置信息一致，如果不一致或差距较大，则说明终端设备上报的位置信息不可靠。
本公开中，可以将参考位置信息与终端设备上报的位置信息进行对比，以验证上报的位置信息是否可靠。
比如，可以将基于GNSS获取的位置信息与基于通信系统确定的终端设备的位置信息进行对比，当基于GNSS获取的位置信息与基于通信系统确定的终端设备的位置信息一致时，可以确定GNSS位置信息可靠，当基于GNSS获取的位置信息与基于通信系统确定的终端设备的位置信息不一致时，可以确定GNSS位置信息不可靠。
再比如，可以将上报的终端设备所在小区的标识与参考位置信息中终端设备所在小区的标识的进行对比，当两终端设备所在小区的标识一致时，可以确定上报的位置信息可靠，当两终端设备所在小区的标识不一致时，可以确定上报的位置信息不可靠。

可选的，如果在预设时间段内，各上报的位置与参考位置间的差值均大于或等于第二门限值，说明上报的位置与参考位置均差别较大，因此，可以确定上报的位置信息不可靠。
