I think LI means Lawful Intercept.
It is a security issue. I recall seeing some ETSI documents about it.

Re: [Int-area] New Version Notification for draft-lhan-problems-requirements-satellite-net-00.txt

[Lin Han]

Hi, Stewart,

What does "LI" stand for?
ISL is not mature enough for real adoption.
The academia research suggested to use laser instead of microwave. When laser 
is used for ISL, there should not have spectrum license issue, I don't see the 
ITU or USA has spectrum allocation for the frequency of laser (400THz~700THz).

I don't have clear answer.
What I can guess now is that most of current technologies (with enhancement)

in satellite power, security in open space, etc.
It is up to the community to decide what new technologies and what new

Lin,

Are you suggesting that the current set of protocols can be used with 
or without enhancements or is the uniqueness of the satellite network require 
new protocol(s) to address the architecture you have laid out..

Hi,

This draft analyzed the problems and requirements for the satellite network 
when it is integrated with Internet by current routing technologies.
It may be relevant and interesting to internet, BGP, IGP. The further solution 
proposals may also come from different groups including research initiative 
SARAH.

Look forwarding to discussion and comments.

Thanks

The thing that worries me about iSL is whether the inability to do LI will 
prohibit licensing in some countries.
