Purpose For information
Attachments Draft new Recommendation ITU-T Y.2326 (ex Y.NGNe-cp_na)
Body
ITU-T Study Group 13 would like to inform about the consent of ITU-T Y.2326
(formerly Y.NGNe-cp_na) “Network attachment control framework in Next
Generation Network evolution control plane”, which has been consented at the
ITU-T SG13 meeting, Geneva, 23 June - 2 July 2026.

ITU-T Y.2326 (formerly Y.NGNe-cp_na) aims to provide a network attachment
control framework for an NGN evolution control plane (NGNe-cp) [ITU-T Y.2325]
architecture that supports decoupling of the signalling handling functionality
and the user plane control functionality in the control plane. In the NGNe-cp
architecture, network attachment is considered a built-in service supported by
using network attachment signalling service functions, which are detailed in
this Recommendation. This is followed by a description of information flows for
the network attachment process using the proposed network attachment control
framework.

ITU-T SG13 looks forward to keeping continued collaboration with you on this
topic.
