Here is a report which summarizes the outcome of the last Satellites
conference
[https://www.microwavejournal.com/articles/39841-satellite-2023-summary-linking-up]
The report highlights the two main hurdles against the integration of
satellites and terrestrial networks: standardization and business model.
"/Most of the pushback against closer integration of terrestrial
wireless and satellite networks revolved around standardization. This
may just be growing pains and it likely reflects the relative
positions of wireless and satellite along the maturity curve, but some
of the speakers were arguing against standardization. The basis of
this argument was that the mobile industry only understands standards,
but the satellite industry is currently differentiating based on
custom systems and capabilities. The feeling was that the satellite
industry had focused on technology and not regulations or standards
and changing that course would not be helpful to the industry in the
short term. Timing is important in this analysis because almost
everyone agreed that at some point, standardization would be a good
thing, but the concern was the best way to get to the point in the
future. The other interesting argument against closer integration
between wireless and satellite had to do with the business model.
Several speakers questioned where the customers would go as
terrestrial and non-terrestrial networks become more integrated. The
underlying issues seemed to include who is responsible for solving
network issues and perhaps more importantly, who recognizes the
revenue. These issues seem, perhaps a bit simplistically, to be
similar to early wireless roaming issues. While these issues created
turbulence in the wireless market, they were solved and that is
probably a template to address these challenges for the wireless and
satellite operators."/

Comments?
It is an interesting report.
For standardisation standpoint, it seems SDOs do push towards
integration of 5G/6G and satcom; there are strong initiatives at least
at 3GPP (NTN WI proposals) and IETF (TVR WG) in that direction. But
these are SDOs traditionally oriented to land communications, rather
than space satcom.
I wonder whether space satcom traditional SDOs (which ones?) have
initiated work towards integration with 5G/6G and other land-based Internet?
