Abstract
There is described a system for authorising a trigger source to issue a trigger request to a device in a network, where the device is operated by a trigger entity authoriser and configured to receive trigger messages only from a trigger server. The trigger entity authoriser sends an initiation message to the trigger server via a secure connection, the initiation message including an indication of the identity of the trigger source and the identity of the device. The trigger entity authoriser and trigger server agree a ticket usable by the trigger server as a unique association of the trigger source and the device. The trigger entity authoriser sends the ticket to the trigger source. The trigger source sends a trigger request message to the trigger server, the trigger request message including a request to trigger the device. The trigger server receives the ticket from the trigger source and authenticates the trigger source and, if the received ticket correctly associates the authenticated trigger source and the device, sends a trigger message to the device.

41. A system for authorizing a trigger source to issue a trigger request to a device in a network, the device being associated with a trigger entity authorizer and configured to receive trigger messages only via a trigger server, the system comprising:
-
the trigger entity authorizer being configured to send an initiation message to the trigger server via a secure connection, the initiation message including an indication of the identity of the trigger source and the identity of the device; the trigger entity authorizer and trigger server being configured to agree on a ticket usable by the trigger server as a unique association of the trigger source and the device; the trigger entity authorizer being configured to send the ticket to the trigger source; the trigger source being configured to send a trigger request message to the trigger server, the trigger request message including the ticket and a request to trigger the device; and the trigger server being configured to receive the ticket from the trigger source and authenticate the trigger source and, if the received ticket correctly associates the authenticated trigger source and the device, to send a trigger message to the device.

42. A trigger entity authorizer for authorizing a trigger source to issue a trigger request to a device in a network, comprising:
-
a processor and a memory, said memory containing instructions executable by said processor to cause the processor to; send an initiation message to a trigger server via a secure connection, the initiation message including an indication of the identity of the trigger source and the identity of the device; send to or receive from the trigger server a ticket associating the trigger source and the device; and send the ticket to the trigger source. - View Dependent Claims (44, 45, 46, 47)

43. A trigger entity authorizer for authorizing a trigger source to issue a trigger request to a device in a network, comprising:
-
a message initiator for sending an initiation message to a trigger server via a secure connection, the initiation message including an indication of the identity of the trigger source and the identity of the device; a ticket negotiator for sending to or receiving from the trigger server a ticket associating the trigger source and the device; and a ticket sender for sending the ticket to the trigger source.

48. A trigger source for issuing a trigger request to a device in a network, comprising:
-
a processor and a memory, said memory containing instructions executable by said processor to cause the processor to; receive a ticket from a trigger entity authorizer, the ticket usable by a trigger server as a unique association of the trigger source and the device; send a trigger request to the trigger server accompanied by the ticket; and authenticate the trigger source to the trigger server. - View Dependent Claims (49, 50, 51)
