The present invention relates to methods, apparatuses and a system in connection with pushing of packet data from an originator to a wireless communication station 20. When a network address is received by the wireless station 20 from a server 50 wishing to push packet data to the wireless station, the received network address is checked against stored predefined network addresses. If the received network address is found among the stored network addresses, the originator is verified, preferably by using an address translation server 40. Thus, in this way it can be determined that the originator indeed belongs to a predefined set of originators from which a mobile user wants to accept pushed packet data transmissions. A packet data session is then established by the wireless station with a verified originator in order to receive the packet data.
