A method for a first intermediate network node (5, 6) for triggering at least one terminal to establish a communication path between the at least one terminal and a server, wherein the communication path includes at least one data connection, the method comprising: receiving a trigger message generated at the server including connection information indicating a first type of the at least one data connection, before transmitting the trigger message to the at least one terminal, the trigger message further including timing information indicating when the communication path between the at least one terminal and the server is to be established; and the method characterised by further comprising: determining whether the first type of the at least one data connection is supported by the at least one terminal and/or allowed for the at least one terminal; upon negative determination, updating the trigger message by replacing the information indicating the first type of the at least one data connection with information indicating a second type of the at least one data connection, where the second type of the at least one data connection is supported by the at least one terminal respectively allowed for the at least one terminal; and transmitting the trigger message from the first intermediate network node to the at least one terminal after the trigger message has been updated. receiving a trigger message generated at the server including connection information indicating a first type of the at least one data connection, before transmitting the trigger message to the at least one terminal, the trigger message further including timing information indicating when the communication path between the at least one terminal and the server is to be established; and the method characterised by further comprising: determining whether the first type of the at least one data connection is supported by the at least one terminal and/or allowed for the at least one terminal; upon negative determination, updating the trigger message by replacing the information indicating the first type of the at least one data connection with information indicating a second type of the at least one data connection, where the second type of the at least one data connection is supported by the at least one terminal respectively allowed for the at least one terminal; and transmitting the trigger message from the first intermediate network node to the at least one terminal after the trigger message has been updated. determining whether the first type of the at least one data connection is supported by the at least one terminal and/or allowed for the at least one terminal; upon negative determination, updating the trigger message by replacing the information indicating the first type of the at least one data connection with information indicating a second type of the at least one data connection, where the second type of the at least one data connection is supported by the at least one terminal respectively allowed for the at least one terminal; and transmitting the trigger message from the first intermediate network node to the at least one terminal after the trigger message has been updated.
