The invention proposes a method for delivering messages in a network comprising at least one terminal device, comprising the steps of generating a message (S1), setting a condition for receiving the message (S2, S3), deciding whether the message is to be received by the terminal device on the basis of the condition (S5, S6), and transmitting the message to the terminal device on the basis of the result of the deciding step (S8). By this method, messages are only transmitted to a terminal device if certain condition, e.g., location conditions, are met. The invention also proposes a network system and a message generating device, a message delivering device and a terminal device adapted to the above method.
