ITU-T Study Groups meeting under the auspices of the NGN Global Standards Initiative (NGN-GSI), July, finalized a substantial body of work. Sixteen new standards went into the final stages of the ITU approval process in areas including requirements, architecture, QoS and security. Around 650 documents were considered by the lead SG on NGN, Study Group 13, alone. Study Group management reported high levels of participation and good progress.

Two rather fundamental documents describing requirements for NGN and describing the functional architecture of the NGN will be published as ITU-T Recommendations after formal approval. Also, QoS, a crucial element as networks move to an environment inherently more susceptible to delay, interference etc. was a key focus, one new Recommendation was consented in this field.

Experts also point to the importance of a Recommendation (ITU-T Rec. Y.2021) describing how the IP multimedia subsystem (IMS) as specified by the 3rd Generation Partnership Project (3GPP) and the 3rd Generation Partnership Project 2 (3GPP2) can be used in the NGN context. A Rec. from Study Group 19 on mobility management was also highlighted, see story here.
