Abstract
Embodiments herein relate to, e.g., a method performed by a source access node relating to handover of a UE. The source access node sends to a target access node, an initial handover preparation message with a first explicit indicator for the target access node to request an enhanced Make-Before-Break Handover. The source access node receives an handover preparation response message from the target access node, with a second explicit indicator accepting or rejecting the requested enhanced Make-Before-Break Handover. Further, the source access node selects a possible fallback mechanism, upon reception of the handover preparation response message from the target access node indicating rejection or no support of enhanced Make-Before-Break Handover.
