Description (partial)

Source-HNB and Target-HNB has aborted the Iurh-Relocation and cleaned -up the resources but Target-HNB didn't inform HNBGW that the ongoing Iurh-Relocation was Aborted.  Thus, HNBGW was maintaining the Iurh-Transient resources until Iurh-Reloc-Guard timer expiry. Hence, another TNL Update Request from same Target-HNB for the same UE-Context gets ignored because HNBGW already has allocated resources for this transient UE.

Iurh Relocation is ongoing for an UE and  in between it is  Cancelled or Aborted by involved HNB and immediately within Iurh-Reloc Guard timer expiry period, another Iurh TNL Update is initiated for the same UE-context by the same Tgt-HNB.
