Abstract

An apparatus, method and computer program is described. The method can include receiving a first measurement report from a first communication node of a mobile communication system. The first measurement report can include downlink measurement data generated at a user device in response to a positioning reference signal sent by the first communication node. The method can further include receiving a second measurement report from the first communication node. The second measurement report can include uplink measurement data generated at the first communication node in response to an uplink reference signal sent by the user device. The method can also include determining an integrity of the measurement data based on a comparison of said uplink and downlink measurement data and setting an integrity verification notification in accordance with the determined integrity.

Claims (55)

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.

2. An apparatus as claimed in claim 1 , wherein determining whether the downlink time delay or time of arrival and the uplink time delay or time of arrival data are consistent comprises determining whether a difference between the downlink time delay or time of arrival and the uplink time delay or time of arrival is below a first threshold.

3. An apparatus as claimed in claim 1 , wherein:

the uplink and downlink measurement data include angle of arrival and angle of departure data; and

determining the integrity of the measurement data determines whether the angle of arrival and angle of departure data are consistent.

4. An apparatus as claimed in claim 1 , wherein the instructions, when executed by the at least one processor, further cause the apparatus at least to:

receive a third measurement report from a second communication node of the mobile communication system, wherein the third measurement report includes uplink measurement data generated at the second communication node in response to the uplink reference signal sent by the user device,

wherein the first measurement report includes downlink measurement data generated at the user device in response to a positioning reference signal sent by the second communication node.

5. An apparatus as claimed in claim 4 , wherein the instructions, when executed by the at least one processor, further cause the apparatus at least to:

determine a first angle between the user device, the first communication node and the second communication node;

determine a second angle between the user device, the second communication node and the first communication node;

determine a first distance between the first communication node and the user device; and

determine a second distance between the second communication node and the user device,

wherein determining the integrity of the measurement data determines whether the first and second angles and the first and second distances are consistent.

6. An apparatus as claimed in claim 4 , wherein the instructions, when executed by the at least one processor, further cause the apparatus at least to:

determine a first angle between the user device, the first communication node and the second communication node;

determine a second angle between the user device, the second communication node and the first communication node; and

determine a third angle between the first communication node, the user device and the second communication node,

7. An apparatus as claimed in claim 4 , wherein the first communication node is a serving base station of the user device and the second communication node is a neighbour base station of the user device.

8. An apparatus as claimed in claim 1 , wherein performing setting the integrity verification notification comprises setting an integrity verification notification signal.

9. An apparatus as claimed in claim 1 , wherein the instructions, when executed by the at least one processor, further cause the apparatus at least to:

send configuration instructions to the first communication node to request said first and second measurement reports.

10. An apparatus as claimed in claim 1 , wherein the instructions, when executed by the at least one processor, further cause the apparatus at least to:

estimate a position of the user device based on angles of arrival of transmissions from the user device at the first communication node and another communication node and the distance between the first communication node and said another communication node.

11. An apparatus, comprising:

at least one processor; and

12. An apparatus as claimed in claim 11 , wherein the integrity verification notification signal indicates whether a difference between the downlink time delay or time of arrival and the uplink time delay or time of arrival is below a first threshold.

13. An apparatus as claimed in claim 11 , wherein the apparatus is a serving base station of the user device.

14. A method comprising:

receiving 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;

receiving 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;

determining 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
