3GPP TR 29.835
studies Port Number Allocation Alternatives for New 3GPP Interfaces. This specification documents the outcome of the study by providing the guidelines for addressing the problem.
IETF has indicated to 3GPP that future IANA port number assignment requests for protocol only used inside 3GPP networks will be likely rejected except if there is a strong justification for it. The present document provides guidelines for resolving the problem with allocating port numbers for new 3GPP interfaces, as an alternative to IANA assigned port numbers.
Starting from 3GPP Rel-17, any 3GPP working group can rely on these guidelines when defining new interfaces, which require new default port number allocation.
The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
References are either specific (identified by date of publication, edition number, version number, etc.) or non specific.
For a specific reference, subsequent revisions do not apply.
For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
