10 Times Beyond LTE-A (5G maybe?)
Recently when I added a presentation by NSN on whats coming after IMT-Advanced, it was very well received and has already had over 8000 views. There seems to be definitely an appetite for the future networks. Here is another such presentation.
There is also a video of the presentation if you have the patience to sit, watch and learn.

Signalling Load per device and OS
From the presentation by Martin Prosek, Telefonica, Czech Republic in 3G Optimization Conference 2012, Prague.
Signalling can cause many issues:
In the mobile device, Frequent PDP-context establishment is known to drain the battery. Battery life can be improved by supporting fast dormancy in network.
In the network, Signalling flood can create situations reminding DoS attacks. Increased signalling in RAN can cause impacts in core network:
- Radius/Diameter interface overload of AAA servers
- DHCP IP address pools exhaustion
