The MME initiates the procedure by sending the HANDOVER REQUEST message to the target eNB. The
HANDOVER REQUEST message may contain the Handover Restriction List IE, which contains roaming or access
restrictions.

For each bearer that target eNB has decided to admit and for which DL forwarding IE is set to “DL forwarding
proposed”, the target eNB may include the DL GTP-TEID IE and the DL Transport Layer Address IE within the E-
RABs Admitted List IE of the HANDOVER REQUEST ACKNOWLEDGE message indicating that it accepts the
proposed forwarding of downlink data for this bearer.
