Mobile networks today see increasingly large numbers of connected user
equipments (UE), allowing users to go beyond voice calling and tap into rich on-line
services. Parallel to this evolution, other devices, such as TV’s, home automation or even
Internet of Things controllers, have become integrated with connectivity capabilities,
allowing them to not only be locally connected, but also be reachable from the Internet. In
this paper we propose a deviceless communication approach, where data and media ﬂows
reaching a user can be individually shifted into nearby devices. To support this, we present
a framework that explores and enhances Software Deﬁned Network and Network Function
Virtualisation concepts, allowing the opportunistic utilization of nearby devices as the user
moves, while still being perceived as a single end-point towards external entities. An
experimental validation scenario is presented, showcasing a video stream being delivered
to a nearby large TV screen, allowing the user to watch the video while a voice call is
routed to a nearby phone. Results showcase the feasibility of the proposed framework and
how virtualisation of both the UE and the points of attachment contribute to reduce the
impact of ﬂow management in the physical devices.
