Abstract

An enhanced solution for controlling a handover procedure for handing a terminal device over from a source cell to a target cell in a communication network with relay nodes is provided. In the solution, the relay nodes actively assist in the handover procedure by, for instance, initiating the handover procedure, configuring a relayed link and buffering user data at the relay node.
