Please find my inputs over this query as following:

ReestabUE-Identity ::=              SEQUENCE {
    c-RNTI                              C-RNTI,
    physCellId                          PhysCellId,
    shortMAC-I                          ShortMAC-I

ReestabUE-Identity IE is sent by the UE in RRCConnectionReestablishmentRequest message. If one of the parameters present in this information element is incorrect or in other words, eNodeB fails to find UE context or security check gets failed . In that scenario, eNodeB responds back to UE with the RRCConnectionReestablishmentReject message.

Waiting for others to respond.
