new subscription management tools driven by LTE?

[Rogelio <scubacuda () gmail com>]

With LTE picking up momentum, what type of new subscription management 
tools will operators need?

(e.g. control complexities of billions of mobile data transactions, 
personalized billing, centralized control across various licensed and 
unlicensed bands, alerts when limits reached, etc.)

Bridgewater is one that I have been looking at lately...

...but I would be curious as to what other companies are seeing out there.
