- Cisco ASR 5000 Series
Known Affected Releases
Symptom: Root Cause : HeNBGW fails to fill proper Transport layer address in the HO Preparation successful outcome when forwarding the msg from MME to Logical ENB and HeNBGW deletes the already established bearer context. Conditions: Scenario : Attach --> IDFT Handover (idft delay 10 sec) --> Handover --> Detach During this 10 sec interval where the UE is in IDFT phase, data traffic will be unsuccessful. The reason why data is not being transferred via indirect tunnel is that fact that during the IDFT phase EBI details in the subscriber context w.r.t source eNB is getting deleted as result of invalid check on DL/UL Optional IDFT Transport Layer Addresses. Also Endmarker will fail to reach source HeNB due to bearer context deletion.
