Hi all,

I am using the following branch of OAI_eNB, OAI_EPC, and srsUE :

OAI_EPC : eb307ebe502b1ca5fb7f1e4b9e30fa1fe34ae8f1 (Master Branch)
OAI_eNB : 9927838e8ccd57be557b130e904bf8caf35cb423 (Develop Branch)
srsUE :     f6d4def6e022eb3b6f9c613265f7961580a3d84d (Next Branch)

I am successfully able to connect the srsUE to OAI_eNB. I am getting issue
in following two scenario:




*Scenario 1:*
When I am using OP = "11111111111111111111111111111111" in hss.conf, and
calculate OPc according to "
https://gitlab.eurecom.fr/oai/openairinterface5g/wikis/SIMInfo". I am able
to connect but mme is crashing within 5 seconds.

*Scenario 2 :*

When I am using OP = ""; in hss.conf. srsUE is getting the IP address but
within the fraction of seconds(~4 sec) RRC connection released and when RRC
connection reestablish srsUE is not getting bearer.
In this case, mme is not crashing.


*I am attaching all necessary logs for scenario 2. I am also attaching conf
files as well.*
