Access control in location tracking system
First Claim
1. A method for controlling access in a location tracking system using a location tracking apparatus comprising a radio network of location tracking nodes disposed in a predetermined coverage area, and an access control apparatus configured to communicate with the location tracking apparatus via the radio network of the location tracking nodes, the method comprising:
- tracking, by the location tracking apparatus, a location of at least one mobile tag in the predetermined coverage area of the location tracking system based on a location update message from the mobile tag or from at least one of the location tracking nodes, wherein the location tracking apparatus comprises a plurality of wireless transceivers operating as said location tracking nodes;
detecting presence of the mobile tag, by the location tracking apparatus on the basis of a current association between the mobile tag and at least one of the location tracking nodes in a determined area, of the predetermined coverage area, associated with said at least one of the locations tracking nodes and at least one access-controlled entity, wherein each access-controlled entity is associated with the access control apparatus deactivated during the detection; and
transmitting an activation signal from the location tracking apparatus to the access control apparatus in response to the detection of the mobile tag in the determined area, in order to activate the access control apparatus to initiate establishment of a wireless communication connection between the mobile tag and the access control apparatus so as to negotiate about access to the access-controlled entity.

8. A location tracking system comprising:
-
a location tracking apparatus comprising a radio network of location tracking nodes disposed in a predetermined coverage area; an access control apparatus configured to communicate with the location tracking apparatus via the radio network of the location tracking nodes; the location tracking apparatus further comprising; at least one processor; and at least one memory including program instructions, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the location tracking apparatus to; track a location of at least one mobile tag in the predetermined coverage area of the location tracking system based on a location update message from the mobile tag or from at least one of the location tracking nodes, wherein the location tracking apparatus comprises a plurality of wireless transceivers operating as said location tracking nodes; detect, on the basis of a current association between the mobile tag and at least one of the location tracking nodes in a determined area, of the predetermined coverage area, associated with said at least one of the location tracking nodes and at least one access-controlled entity, wherein each access-controlled entity is associated with access control apparatus deactivated during the detection; and transmit an activation signal from the location tracking apparatus to the access control apparatus, in response to the detection of the mobile tag in the determined area, in order to activate the access control apparatus to initiate establishment of a wireless communication connection between the mobile tag and the access control apparatus so as to negotiate about access to the access-controlled entity. - View Dependent Claims (9, 10, 11, 12, 13, 14, 16)

15. A computer program product embodied on a non-transitory distribution medium readable by a computer and comprising program instructions which, when loaded into an apparatus, uses a location tracking comprising a radio network of location tracking nodes disposed in a predetermined coverage area, and an access control apparatus configured to communicate with the location tracking apparatus via the radio network of the location tracking nodes, to execute a computer process comprising:
-
tracking a location of at least one mobile tag in the predetermined coverage area of the location tracking system based on a location update message from the mobile tag or from at least one of the location tracking nodes, wherein the location tracking apparatus comprises a plurality of wireless transceivers operating as said location tracking nodes; detecting presence of the mobile tag, by the location tracking apparatus on the basis of a current association between the mobile tag and at least one of the location tracking nodes in a determined area, of the predetermined coverage area, associated with said at least one of the location tracking nodes and at least one access-controlled entity, wherein each access-controlled entity is associated with the access control apparatus deactivated during the detection; and transmitting an activation signal from the location tracking apparatus to the access control apparatus in response to the detection of the mobile tag in the determined area in order to activate the access control apparatus to initiate establishment of a wireless communication connection between the mobile tag and the access control apparatus so as to negotiate about access to the access-controlled entity.
