为详细说明本申请实施例提供的移动通信系统的完好性保护方法，以下将结合几个具体的实施例进行说明。
实施例一
如图3所示，该实施例包括如下步骤。
步骤1：UE获得完好性能力。该实施例中，UE内设置有完好性保护系统。
步骤2：UE通过定位协议向LMF上报自身的完好性能力。
步骤3：定位流程发起。具体地，可以由定位服务器向LMF发送定位服务请求，以实现UE的定位。
步骤4：LMF向UE发送定位辅助数据，同时，还可以携带LMF支持的完好性能力。
步骤5：UE进行定位测量，得到定位信息(或称位置信息)。
步骤6：UE栈(stack)向UE应用发送带精度的定位信息。
步骤7：完好性保护系统对定位信息进行校正。该实施例中的完好性保护系统可以参见图3中的RAIM。
步骤8：完好性保护系统将校正后的定位信息(即经过完保的数据)提 供给UE栈。
步骤9：UE栈将经过完保的数据发送给LMF，具体可以参见前文实施例中的第三信息。
步骤10：LMF将上述经过完保的数据发送给定位服务器。
步骤11：定位服务器端可能也存在上述完好性保护系统，因此，还可以通过完好性保护系统校验单个UE的位置信息，还可以统计多个UE的位置信息。
实施例二
该实施例类似实施例一，实施例二中进行定位的不是UE和网络侧设备，而是UE和UE。该实施例二通过采样大量UE和UE之间定位信息，定位单次UE定位的准确性。
该实施例二中的UE1相当于实施例一的UE，该实施例二中的UE2相当于实施例一的网络侧设备，该网络侧设备包括LMF和定位服务器。
实施例三
如图4所示，该实施例包括如下步骤。
该实施例三与实施例一的区别从第6步开始，不同于实施例一，该实施例中测量的定位信息不在UE侧进行完好性校验，而是由UE上报网络侧设备，由网络侧设备进行完保校验，再将校验结果发回UE。
该实施例的步骤1至步骤5参见实施例一，以下将从步骤6开始介绍。
步骤6：UE栈向LMF发送带精度的定位信息。
步骤7：LMF向定位服务器发送上述带精度的定位信息。该实施例中的完好性保护系统可以参见图4中的RAIM，位于定位服务器侧。
步骤8：完好性保护系统对定位信息进行校正。
步骤9：定位服务器将校正后的数据(可以是校正后定位信息)提供给UE应用。
步骤10：UE应用将校正后的数据提供给UE栈。
步骤11：UE可能也存在上述完好性保护系统，因此，还可以对上述校 正后的数据进行再次校正，提高定位信息的精度。
实施例四
如图5所示，该实施例包括如下步骤。
步骤1：gNB向LMF发送自身的错误信息。
步骤2：UE定位时，LMF将携带有上述错误信息的定位辅助数据发送给UE，使得UE在定位时可以充分考虑该错误信息。
在另一种实施方式中，如图5的步骤3和步骤4所示，LMF将携带有上述错误信息的定位辅助数据发送给gNB，再由gNB转发给UE，使得终端在定位时可以充分考虑该错误信息。
步骤5：UE进行定位测量。
该实施例的后续步骤还可以参见实施例一的步骤6至步骤11。
