1. An apparatus, comprising:
at least one processor; and
at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least:
receive a first measurement report from a first communication node of a mobile communication system, wherein the first measurement report includes downlink measurement data generated at a user device in response to a positioning reference signal sent by the first communication node;
receive a second measurement report from the first communication node, wherein the second measurement report includes uplink measurement data generated at the first communication node in response to an uplink reference signal sent by the user device;
determine an integrity of the measurement data based on whether the measurement data is reliable, wherein the reliability of the measurement data is based on whether the uplink and downlink measurement data are consistent, wherein the downlink measurement data includes downlink time delay or time of arrival data and the uplink measurement data includes uplink time delay or time of arrival data, and the integrity of the measurement data is determined based on whether the uplink and downlink time delay or time of arrival data are consistent; and
set an integrity verification notification in accordance with the determined integrity.
