Abstract

The present invention relates to device triggering in case of a congestion control. A triggering server transmits a device trigger request to a terminal over a communication network including a serving network node. The network node evaluates whether the connection can be established from the terminal to the server, including determining whether the network is congested and/or whether a back-off timer is running and/or the remaining time of the back-off timer at the terminal. Then the network node transmits a delivery delay indication to a device triggering control server to provide it with the delivery delay indication indicating at least one of impossibility of establishing the connection to the server after the trigger or a data transmission delay.
