new subscription management tools driven by LTE?

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.
