I came across a S1-AP pcap, some time back, in which the SCTP dest port was M2UA but the PPID was 18(S1-AP). In what scenario is M2UA encapsulation over SCTP used when SCTP has 36412 port reserved for S1-AP? (I am trying to get hold of that pcap)
WHY MME USES UDP AS TRANSPORT PROTOCOL OVER SCTP TOWARDS SGW
