An end-point device comprises multiple communication transceivers via which the end-point device associates with multiple access points. The multiple access points may belong to packet switched data networks that are communicatively incompatible. Each of the associated access points contributes a separate pathway for flow of data packets between the end-point device and a backbone network that communicatively connects all associated access points. Each of the associated access points receives and stores unique network addresses assigned to the end-point device by the associated access points and information corresponding to the associated pathways in respective memories. Each of the associated access points delivers data packets directly to the end-point device and / or indirectly via the backbone network and one of the remaining associated access points. An access point selects an indirect path via the backbone network for delivering the data packets based on the information received from the end-point device and / or a variety of communication characteristics. The access point uses a unique network address assigned by another access point to the end-point device when it routes the data packets via the another access point.

A method of deliveries data and to a mobile node for receiving data delivered from a packet-switched data network. A first registration of the mobile node is performed to a first network of a first access technology, and an additional second registration of the mobile node is performed to a second network of a second access technology by using an address associated with the mobile node in said first network. An interface of the mobile node towards the second network is deactivated and the mobile node is set into an idle mode of the first network. When an incoming signaling of the first network is received at the mobile node, it is used as a trigger for activating the interface to the second network. Thereby, efficient data delivery via the second access technology, for example, 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, for example, cellular technology.
