TRANSPORT NETWORK RELAYING IN ENERGY EFFICIENT NETWORKS

摘要

The embodiments herein relate to a method in a first network node (215) for handling transport network data traffic in a first base station (201). The first base station (201) comprises a transport network transmission equipment (205) and the transport network transmission equipment (205) is a part of the transport network. When the first base station (201) is in a sleep mode, the first network node (215) determines (306, 801) that the transport network transmission equipment (205) should be bypassed by activating a relay (209) comprised in the first base station (201) such that data traffic from a second network node (217) is transmitted via the relay (209) to a third network node (220).
