Abstract

A method is disclosed that includes obtaining one or more pieces of threat information indicative of a data set enabling positioning based on radio signals sent by a respective radio node. The data set is further indicative of one or more parameters based on which said positioning is performed and/or controlled and which is considered to be at least partially unexpected. The method also includes utilizing the one or more pieces of threat information in a positioning. In order to obtain the one or more pieces of threat information, the method includes at least one of: obtaining the one or more pieces of threat information by using an application programming interface; or obtaining the one or more pieces of spoofing information by using a push method. A corresponding apparatus, computer-readable storage medium and system are also disclosed.

First claim

That which is claimed is:

1. A first method, performed by at least one mobile device, comprising:
obtaining one or more pieces of threat information indicative of a data set enabling positioning based on radio signals sent by a respective radio node, the one or more pieces of threat information (a) identifying the respective radio node, (b) indicating one or more of (i) a node radio type of the respective radio node or (ii) a node frequency-band of the respective radio node, and (c) comprising respective timestamp information, and wherein the data set is further indicative of one or more parameters based on which said positioning is performed and/or controlled and which is considered to be at least partially unexpected;
comparing the respective timestamp information associated with respective threat information of the one or more pieces of threat information to at least one other respective timestamp information associated with another respective threat information of the one or more pieces of threat information;
based on a result of the comparing, selecting at least one most recent piece of threat information from the one or more pieces of threat information; and
utilizing the at least one most recent piece of threat information of the one or more pieces of threat information in performing said positioning, the at least one most recent piece of threat information comprising respective timestamp information indicating the at least one most recent piece of threat information is real-time information with respect to said positioning,
wherein the obtaining of the one or more pieces of threat information is at least one of:
obtaining the one or more pieces of threat information by using an application programming interface; or
obtaining the one or more pieces of threat information by using a push method.

2. The first method according to claim 1 , wherein the one or more parameters comprise or represent one or more of:
i) radio-type information indicative of at least one radio type that is considered to be potentially manipulated;
ii) frequency-band information indicative of at least one frequency-band that is considered to be potentially manipulated;
iii) an identifier of at least one radio node enabling positioning that is considered to be potentially manipulated;
iv) influencing information indicative of a certain type of influence that is considered to be potentially manipulated and/or if certain type of influence is continuous or sporadic or periodic; or
v) detection information indicative of whether or not detection of manipulation is reliable or uncertain.

3. The first method according to claim 1 , wherein a respective threat information of the one or more pieces of threat information is indicative of at least one of spoofing, jamming, or meaconing threats to the positioning.

4. The first method according to claim 1 , further comprising:
determining at least one affected radio node based on the one or more pieces of threat information; and
blocking the at least one affected radio node from being utilized in the positioning.

5. The first method according to claim 1 , further comprising checking timestamp information by:
checking a position of the at least one mobile device with a location associated with a respective parameter of the one or more parameters, wherein respective pieces of the one or more pieces of threat information that are associated with the position of the at least one mobile device are utilized in the positioning; and/or
checking a capability information indicative of at least one capability utilized in the positioning, and that is associated with a respective threat information of the one or more pieces of threat information with certain capabilities of the at least one mobile device, wherein a respective piece of threat information of the one or more pieces of threat information, that is relevant considering the certain capabilities of the at least one mobile device, is utilized in the positioning.

6. The first method according to claim 5 , wherein the certain capabilities of the at least one mobile device are indicative of one or more of:
i) radio-type capabilities of the at least one mobile device; or
ii) frequency-band capabilities of the at least one mobile device.

7. The first method according to claim 1 , wherein the positioning is a global navigation satellite system (GNSS) and/or a non-GNSS positioning, wherein the non-GNSS positioning is at least one of:
a radio-network based positioning; or
a sensor-based positioning.

8. The first method according to claim 1 , wherein the data set further comprises a position information indicative of a position of at least one radio node enabling positioning that is considered to be potentially unexpected, or wherein the position information is determined based on identification information of at least one radio node enabling positioning that is considered to be potentially manipulated.

9. The first method according to claim 1 , further comprising:
gathering a second data set based on radio signals of one or more radio nodes enabling positioning; and
outputting the second data set together with a timestamp information indicative of a time and/or date at which the second data set was gathered.

10. The method according to claim 1 , further comprising replacing at least one outdated piece of threat information with a respective threat information.

11. The method according to claim 1 , further comprising polling the application programming interface, wherein the one or more pieces of threat information are obtained as a result of polling the application programming interface.

12. A second method, performed by at least one apparatus, comprising:
obtaining one or more pieces of data sets, wherein each data set of the one or more pieces of data sets (a) enables positioning based on radio signals sent by a respective radio node, (b) is indicative of one or more parameters based on which said positioning is performed and/or controlled and which is considered to be at least partially unexpected, and (c) is associated with a timestamp information;
forming said one or more pieces of data sets into one or more pieces of threat information, each of the one or more pieces of threat information (a) identifying the respective radio node and (b) indicating one or more of (i) a node radio type of the respective radio node or (ii) a node frequency-band of the respective radio node;
filtering said one or more pieces of threat information based on (a) a position estimate of an intended recipient and (b) radio capabilities of said intended recipient; and
providing the filtered one or more pieces of threat information by using an application programming interface, and/or by using a push method for receipt by said intended recipient;
wherein the filtered one or more pieces of threat information are utilized by said intended recipient in performing said positioning.

13. The second method according to claim 12 , wherein only a part of the one or more pieces of threat information is provided dependent upon a position, and/or upon one or more capabilities of a respective mobile device to which the part of the one or more pieces of threat information is provided.

14. The second method according to claim 12 , wherein a respective data set of the one or more pieces of data sets is associated with a timestamp information indicative of a time and/or date at which the respective data set was gathered prior to the obtaining of said respective data set.

15. The second method according to claim 12 , wherein the one or more parameters comprise or represent o
