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
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.
