It’s not wise for the HSGW to allocate resource for receipt of forward data during the Pre-registration phase because the mobile may stay in LTE for a long time before execute handover, in some case may not execute handover for ever eAN is aware of handover preparation while ePCF and HSGW are not aware of handover preparation. Therefore eAN knows the right time to trigger allocation of data forwarding address So there shall be such an indicator in both A9 and A11 messages
