Which in-line service do most customers currently use?

Question

Options

• Atraffic characterization
• Brate-limiting
• Cenhanced charging
• Dcontent filtering

• A
  8% (3)
• B
  3% (1)
• C
  88% (35)
• D
  3% (1)

Explanation

Enhanced charging is the correct answer because it is the foundational revenue-generating function that virtually every mobile and broadband operator must deploy - billing customers accurately for data usage is a non-negotiable business requirement, making it the most universally adopted in-line service across the industry.

Why the distractors are wrong:

• A. Traffic characterization is often a component used to enable other services (like charging), not a standalone service most customers deploy on its own.
• B. Rate-limiting is selectively applied for congestion management or policy enforcement, but not deployed as broadly as charging.
• D. Content filtering is used in specific contexts (parental controls, regulatory compliance), making it a niche service rather than a near-universal one.

Memory tip: Think "C for Cash" - Enhanced Charging is what keeps operators in business, so it's always the first in-line service turned on. Revenue before everything else.
