Abstract

A method in a location service client node includes maintaining a database containing a listing of beacon radio node identifiers with their geographic locations. A received location request contains an identifier for a UE and an identifier for a beacon radio node. A geographic location of the UE is determined from the database using the geographic location of the identifier for the beacon radio nodes. A message is sent to a public safety system containing the identifier for the UE and the geographic location. Subsequent to sending the message to the public safety system, a received movement notification message contains the identifier for the beacon radio node and data indicating that the beacon radio node has been moved. Data in the database is set to prevent the geographic location of the beacon radio node from being subsequently used to determine the geographic location of a UE.

First claim

What is claimed is:

1 . A method in a location service client node, the method comprising:
maintaining a database containing a listing of beacon radio node identifiers with their geographic locations; receiving a location request containing an identifier for a user equipment node (UE) and an identifier for one of the beacon radio nodes; determining a geographic location of the UE based on obtaining from the database the geographic location of the identifier for the one of the beacon radio nodes received in the location request; sending to a public safety system a message containing the identifier for the UE and the geographic location obtained from the database; subsequent to sending the message to the public safety system, receiving a movement notification message containing the identifier for the one of the beacon radio nodes and data indicating that the one of the beacon radio nodes has been moved; and based on receipt of the movement notification message indicating that the one of the beacon radio nodes has been moved, setting data in the database to prevent the geographic location of the one of the beacon radio nodes in the listing maintained in the database from being subsequently used to determine the geographic location of a UE.

2 . The method of claim 1 , wherein the setting data in the database to prevent the geographic location of the one of the beacon radio nodes in the listing maintained in the database from being subsequently used to determine the geographic location of the UE, comprises:
modifying the listing maintained in the database to indicated that the one of the beacon radio nodes is blacklisted responsive to the receipt of the movement notification message containing the identifier for the one of the beacon radio nodes; and preventing the geographic location of any blacklisted ones of the beacon radio nodes in the listing maintained in the database from being used to determine the geographic location of a UE.

3 . The method of claim 1 ,
wherein the movement notification message further contains data indicating an elapsed time during which the beacon radio node was experiencing movement; and further comprising:
based on determining that the elapsed time is less than a threshold time, not performing the method of setting data in the database to prevent the geographic location of the one of the beacon radio nodes in the listing maintained in the database from being subsequently used to determine the geographic location of the UE; and
based on determining that the elapsed time is greater than a threshold time, performing the method of setting data in the database to prevent the geographic location of the one of the beacon radio nodes in the listing maintained in the database from being subsequently used to determine the geographic location of the UE.

4 . The method of claim 1 ,
wherein the movement notification message further contains data indicating whether supply of external power to the beacon radio node was terminated while the beacon radio node was experiencing movement; and further comprising:
based on determining that the supply of external power to the beacon radio node was not terminated while the beacon radio node was experiencing movement, not performing the method of setting data in the database to prevent the geographic location of the one of the beacon radio nodes in the listing maintained in the database from being subsequently used to determine the geographic location of the UE; and
based on determining that the supply of external power to the beacon radio node was terminated while the beacon radio node was experiencing movement, performing the method of setting data in the database to prevent the geographic location of the one of the beacon radio nodes in the listing maintained in the database from being subsequently used to determine the geographic location of the UE.

5 . The method of claim 4 ,
wherein the movement notification message further contains data indicating an elapsed time during which the supply of external power to the beacon radio node was terminated while the beacon radio node was experiencing movement; and further comprising:
based on determining that the elapsed time is less than a threshold time, not performing the method of setting data in the database to prevent the geographic location of the one of the beacon radio nodes in the listing maintained in the database from being subsequently used to determine the geographic location of the UE; and
based on determining that the elapsed time is greater than a threshold time, performing the method of setting data in the database to prevent the geographic location of the one of the beacon radio nodes in the listing maintained in the database from being subsequently used to determine the geographic location of the UE.

6 . The method of claim 1 , further comprising:
based on receipt of the movement notification message, determining whether an earthquake occurred in a geographic region that includes the one of the beacon radio nodes within a threshold time before the receipt of the movement notification message; based on determining that an earthquake did occur within the threshold time, not performing the method of setting data in the database to prevent the geographic location of the one of the beacon radio nodes in the listing maintained in the database from being subsequently used to determine the geographic location of the UE; and based on determining that an earthquake did not occur within the threshold time, performing the method of setting data in the database to prevent the geographic location of the one of the beacon radio nodes in the listing maintained in the database from being subsequently used to determine the geographic location of the UE.

7 . The method of claim 6 , wherein the determining whether an earthquake occurred in a geographic region that includes the geographic location of the one of the beacon radio nodes within a threshold time before the receipt of the movement notification message, comprises:
determining whether within a threshold time of receipt of the movement notification message, movement notification messages are received from other beacon radio nodes that are within a threshold distance of the one of the beacon radio nodes.

8 . The method of claim 1 ,
wherein the movement notification message further contains an identifier for another one of the beacon radio nodes that is received by the one of the beacon radio nodes after the movement has ceased; and further comprising:
obtaining from the database the geographic locations of both of the beacon radio nodes identified by the movement notification message;
comparing the geographic locations of both of the beacon radio nodes identified by the movement notification message;
based on the comparison satisfying a defined geographic proximity rule, not performing the method of setting data in the database to prevent the geographic location of the one of the beacon radio nodes in the listing maintained in the database from being subsequently used to determine the geographic location of the UE; and
based on the comparison not satisfying the defined proximity rule, performing the method of setting data in the database to prevent the geographic location of the one of the beacon radio nodes in the listing maintained in the database from being subsequently used to determine the geographic location of the UE.

9 . The method of claim 1 , further comprising:
based on receipt of the movement notification message indicating that the one of the beacon radio nodes has been moved, determining based on information in the database whether the movement has been authorized; and based on determining that the movement has be
