      Description

      We might have to drop support in R5 for this REST interface due to this:

      https://wiki.o-ran-sc.org/pages/viewpage.action?pageId=20874584#E2ManagerR5InterfaceDesign(Draft)-8.GetAllNodeBStatesRequest(Changed,StretchGoal)

       

      Error message:

      {"ts":1590746144632,"crit":"ERROR","id":"E2Terminator","mdc":

      {"thread id":"W13993801206348 "}

      ,"msg":"Error 1 Decoding (unpack) E2SM message from : E2SM-gNB-NRT-RANfunction-Definition"}

      It points to function RAN_Function_list_To_Vector() in “sctpThread.cpp”, which I guess translates the ASN.1 from PER to XER (XML) before sending to E2SM.

       

      There are many potential short and long-term solution.

      Long-term one would be to have some kind of plugin approach. This plugin could be a E2SM function handling xApp that is potentially combined with actual "xApp functionality". But it could be also a simple E2SM-function definition encoding to which E2M can outsource the decoding of the function definitions.
