•       Polaris Networks gave a demo to ONF regarding the various ways of testing contribution to be done on M-CORD platform.

•       Polaris started deploying M-CORD 4.1 where it was met with various initial challenges in CiaB environment.

•       After the M-CORD deployment was completed than Polaris EPC was included as a service in M-CORD platform.

•       Polaris EPC was used against Intel SPGW on M-CORD platform for testing.

•       Polaris found that during UE attach, SPGW is throwing an error " Dropping packet , Error on message GTP_CREATE_SESSION_REQ: (-1) Operation not permitted..".

•       Debugging further, it was noticed that SPGW was looking for an IE viz. MSISDN_IE in create session request as a mandatory IE.

•       According to 3GPP, MSISDN_IE is conditional in Create session request on S11.

•       After adding MSISDN_IE in CSR, SPGW was able to successfully send ' Create Session Response'.

•       Polaris did a UE attach/Detach with Polaris EPC within M-CORD and gave a demo to ONF which was also attended by Intel and NG4T.

•       Polaris found that Gx interface was missing in 4.1 release.

•       Polaris tried sending data over Intel SPGW and noticed that the UDP packet is reaching S1U interface but not coming out of SGi interface.

•       Polaris went into a debug session with Intel to fix the above issue and was able to do it.

•       In an reference setup, Polaris was able to send and receive data over Intel SPGW.
