Abstract
A network node (100) enabled to work, within a cellular communication system comprising a plurality of base stations (102), according to a device-to-device, D2D communication mode is disclosed. The network node (100) can also have backhaul (600) capability via a second communication network (602) distinct from a backbone network (502) of the cellular communication network and is enabled to provide D2D communication by direct or multi-hop communication with other nodes or terminals (104, 106) on a peer level for providing service via the second communication network (602) when operating in the D2D communication mode. The network node (100) can have backhaul (500) capability via a backbone network (502) of the cellular communication network, wherein the network node (100) is further enabled to work according to a device-to-device, D2D communication mode within and under control of the cellular communication network. Methods and computer program are also disclosed.
