Technical Details

what runs on :36444

M3AP uses SCTP on port 36444 and carries 3GPP control messages for the M3 interface, including MBMS session and coordination procedures. Messages use ASN.1 encoding; SCTP provides the transport association and message delivery, but does not itself encrypt the traffic. This is distinct from M3UA, a separate SIGTRAN protocol commonly associated with SCTP port 2905.

security overview

This is telecom control-plane traffic and should be reachable only by authorized MME and MCE systems on a trusted operator network. SCTP does not provide confidentiality, and an exposed endpoint may invite probing or attempts to disrupt or inject signaling; use network filtering and the operator's network-domain security protections, such as IPsec where applicable. It is not normally intended for public-internet exposure.

Record

iana registry entry

port: :36444
service: M3 Application Part (M3AP)
transport: SCTP
encryption: cleartext
assignment: iana registered
risk: 6/10risk
category: Network Services Mobile
usage: M3AP is the 3GPP control-plane protocol for the M3 interface between an MME and a Multi-cell/multicast Coordination Entity (MCE) in LTE MBMS networks. Engineers are most likely to encounter it inside a mobile operator's core network, not on general-purpose internet hosts.
