Purpose: For information

Body: 1. Overall Description:

The 3GPP Technical Specification Groups (responsible of the technical specification development work within 3GPP) have decided to undertake a specific work in Rel-17 on the specification of alternative solutions for port allocation for new 3GPP interfaces from Rel-17 onwards, that will avoid future IANA port number assignment requests for network internal services. The description of the corresponding 3GPP Work Item should be discussed and approved in Sept 2020. 

The solutions that will be defined in Rel-17 will not be ready for many months and therefore cannot be applied to the W1 interface. Instead due to more urgent timescales, 3GPP needs the approval of the IANA port number assignment request for the W1 interface (IANA#1172452) and asks the IESG to take account of the present situation and give the request due consideration. 

2. Actions:
To IESG group
ACTION: 	3GPP kindly asks IESG to approve the IANA request.

3. Date of Next CT Meetings:
3GPP TSG CT #89e	September 2020	e-Meeting
