Device triggering and apn-based congestion control

摘要

The present invention relates to device triggering in a communication system. Accordingly a triggering server triggers a terminal for establishing connection and/or transmitting data in response to the trigger request obtained from the server. In case of congestion, the terminal or a network node, serving the terminal in the network connecting the terminal to the server, transmits to the server an indicator for indicating whether the data will be delivered or not and/or the delivery delay. The present invention provides respective methods to be executed at the terminal, network node, and/or the server as well as a terminal, a network node, and/or a server implementing such functionality.
