While going through the NAS protocol, One section has mentioned about attach in S101 mode . I didn't get the context.
Can someone please share his/her thoughts on this context ?
Thanks in advance.

I don't have deep understanding of S101 interface. I went through the different reference materials and would like to share what I got as following:

  • S101 interface is based on GTPv2-C protocol.
  • S101 interface is used to enable handover signalling between E-UTRAN and CDMA2000 networks.
  • S101 interface exists between MME (LTE network node) and HRPD (CDMA2000 network node)
  • All the signalling messages over the S101 interface don't use TEID in message header.
  • PMIP protocol is used to carry signalling and data packets.

Due to very limited knowledge in this interface. I explained a little bit.
Expecting response from other telecom professionals as well.
And also please correct me if I wrote something wrong.

I saw a scenario where an Identity is requested by MME after successful Authentication and Security mode complete.. As a Response to this message UE is Sending IMEI? what is the need of checking IMEI number after successful authentication? If IMEI is in block list then ongoing Attach procedure is going to be Terminate...? Identity Request intention is mainly to check the IMEI belongs to any one of Black, while or Green list then why cannt MME check for this before Security Mode?
