Method, network elements, a terminal, a network infrastructure, and a communication system for triggering events

An apparatus, comprising:

• a detector configured to detect a terminal-related event of a lower protocol layer of a protocol layer stack, a lower layer event;
• a determiner configured to determine a necessity for a network-related event of a higher protocol layer of the protocol layer stack, a higher layer event, on the basis of the detected lower layer event;
• an initiating unit configured to initiate, on behalf of a network element, the higher layer event to be rendered effective at a terminal, if the determiner yields a necessity for the higher layer event to be triggered;
• a receiver configured to receive current information on the higher layer event from the network element;
• and
• wherein the initiating unit is configured to initiate the higher layer event based on the stored information.

An apparatus, comprising:

• a determiner configured to determine a necessity for a network-related event of a higher protocol layer of the protocol layer stack, a higher layer event, on the basis of the detected lower layer event;
• a requesting unit configured to send a request for the higher layer event to a network element, if the determiner yields a necessity for the higher layer event to be triggered, the request being based on the detected lower layer event;
• and
• a relaying unit configured to relay the higher layer event being initiated at the network element to a terminal.

• a determiner configured to determine a necessity for the higher layer event on the basis of the detected lower layer event;
• and
• an initiating unit configured to initiate, based on the received request, the higher layer event to be rendered effective at a terminal, if the determiner yields a necessity for the higher layer event to be triggered.
