Satellite Access in FPLMTS
Robert J Finean
This thesis demonstrated why satellite access to third generation mobile
systems will be valuable and how the UMTS Network Architecture developed
in Europe can support satellites and their
spectrally efficient channel assignment schemes.
It also predicted the need for third generation applications to adapt
to the wide range of communication facilities available depending on
their terminal's environment and for B-ISDN to have protocols enabling
this adaptation in mobile networks.
Original ideas included:
- Clearly defined valuable roles that satellites will play in accessing
3G networks (this is particularly interesting following
Iridium's bankruptcy then
ICO's and Globalstar's merging with
McCaw's cellular interests)
- Giving the FES the pivotal role of guaranteeing communications
with mobile terminals in a rigidly defined geographic area
- Developing the UMTS network architecture to allow network designers
the freedom to implement the FES to mobile terminals
communications in any way
- Developing the UMTS network architecture to allow FESs to control
handovers within their geographic service area in a pre-emptive way,
based on predictable satellite motion and traffic distribution
(this is how ICO works)
- A detailed study of the performance of DCA algorithms in these non-GEO
(such dynamic schemes are still not deployed in systems like ICO,
which use more conservative spectrum planning)
- Recognition that UMTS cannot offer 2Mbit/s service at a marketable price
in all environments and that UMTS applications will have to adapt
to varying grades of communication services during a call.
("Teletext" versions of some websites were launched for i-Mode
and WAP but such rewriting of web pages for mobile channels
has not been a successful example of how 3G phones will interwork
with the desktop Internet applications that people are familiar with.
Even in 2001 there was still a disturbing amount of hype regarding
the capabilities of mobile and satellite access in the marketplace:
took the initiative to bridge the gap between what mobile
customers want from their phone/PDA and what even pre-GPRS
GSM networks could deliver.)
