Hello,
a little question 
For mobile operators using v6 on their networks, how do you manage
link-local communication between mobile phones ?
While I understand it's layer 2 related, am i able for example to make
ping sweep and be able to communicate directly with other phone (customer) ?
No. Your phone has a tunnel to a node in the mobile network and that's the only one you can send packets to. It's a GTP tunnel, but it's very similar to GRE or IPIP or whatever.

the link local address is bound to eps bearer the other end of which is
the p-gw.
so it's a point-to-point link.
so you say what about the radio bearer?
there are two kinds, the srb where signalling is present, and the user
data which is associated with an eps databearer.

appart from your nexthop, no.
