IANA registration requests tracking
The table below tracks registration requests to be made to IANA. Applications for new entries must be made by the specifications rapporteur via email to the 3GPP Specifications manager.
Note: dates are MM/DD/YYYY.

Note: IANA assignment requests for new UDP/TCP port numbers shall be strongly justified, as IETF has clearly indicated that unjustified port number assignment requests will be rejected. The TR 29.941 should be used to decide whether an alternative to IANA UDP port assignment could be rather used.
