The present invention relates to a method of delivering data and to a mobile node (50) for receiving data delivered from a packet-switched data network (36). A first registration of the mobile node (50) is performed to a first network (38) of a first access technology, and an additional second registration of the mobile node is performed to a second network (30) of a second access technology by using an address associated with said mobile node in said first network (38). Then, an interface of the mobile node (50) towards the second network (30) is deactivated and the mobile node (50) is set into an idle mode of the first network (38). When an incoming signaling of the first network (38) is received at the mobile node (50), it is used as a trigger for activating the interface to the second network (30). Thereby, efficient data delivery via the second access technology, e.g. WLAN technology, is allowed to bring down the communications charges and yet cellular efficient power consumption is achieved in idle mode, by camping on the first access technology, e.g., cellular technology. |
