Billing in the telecommunications industry, particularly for
the larger companies, is a very hard problem. There are many
complicating factors, ranging from extremely high volumes of complex
data to 20-year-old legacy systems to extremely complicated and
arbitrary billing algorithms, that synergistically combine to create a
very difficult problem. This talk will describe the billing problem
from a computer science point of view; that is, it will describe the
quantitative issues, the computational problems, and the operational
concerns.
