Hi, Protocol-IEs, MMEname and ENBname, cant be decoded\encoded properly, definitely. I am using open5g-mme. When IE=MMEname is turned off, test can pass or used till the end.
Amazing progress with S1AP emulation, congrats.
If I misuse this group with the topic, be free to tell me.

Hi, Osmonians, I don't know where to write for MME TTCN-3, so I chose to write to it closet relative - SGSN.
I was trying to do slight modification to TTCN-3 code, modifing S1AP_Templates.ttcn.
I embedded enodeb name for all tests with new protoc-IE = id-eNBname : ################################## template (value) S1AP_PDU ts_S1AP_SetupReq(template (value) Global_ENB_ID p_global_ENB_ID, template (value) SupportedTAs p_supportedTAs, template (value) PagingDRX p_pagingDRXs) := { initiatingMessage := { procedureCode := id_S1Setup, criticality := reject, value_ := { S1SetupRequest := { protocolIEs := { { id := S1AP_Constants.id_Global_ENB_ID, criticality := ignore, value_ := { Global_ENB_ID := p_global_ENB_ID } }, { id := S1AP_Constants.id_SupportedTAs, criticality := reject, value_ := {SupportedTAs := p_supportedTAs} }, { id := S1AP_Constants.id_eNBname,//id-eNBname criticality := ignore, value_ := {ENBname := "OsmoEnodeb"} } /* HACK: work around nextepc bug , { id := S1AP_Constants.id_pagingDRX, criticality := ignore, value_ := {PagingDRX := p_pagingDRXs} } */ } } } } } ########################
Code compiles, but PDU is not encoded well. I attached Wireshark preview.
Can you help me with this issue ?
