The following protocol flow shows a hard local handover in TFO, where the local TRAU changes. New BTS and new TRAU are synchronised and working before the handover takes place. On the TFO Interface the fast handover handling is applied. The handling of the Handover_Complete Message on the distant side is as described for the Intra BSC handover (not shown here again).
