Patent ID: 8738482

Claim:
A method for preparing an optimal alternative billing plan for mobile telephony operators managed through a call center, based on processing by at least one first service server of information relating to billing of different telecommunication services used by a customer, including duration and time slot of use, the method comprising: (a) estimating a real bill of the customer during a selected time period covering M preceding months, using a processor of the at least one first service server, by processing accumulated mean traffic, extrapolated to the M preceding months, obtaining a mean consumption of the customer in the selected time period; (b) simulating estimating a bill of the customer using at least one generic plan based on the accumulated mean traffic of the M preceding months, by using the processor to apply a simulation algorithm; (c) estimating a churn risk of the customer, using the processor, according to a value of the customer, a value of operators on the market, a number of better offers, a number of customers called per operator, and the simulations performed with the at least one generic plan, applying a churn risk algorithm; and (d) selecting an alternative plan and presenting to the customer the selected alternative plan in the form of a recommendation, wherein the (a) estimating the real bill, the (b) simulating estimating the bill, and the (c) estimating the churn risk are performed by the processor using data supplied by the first service server.
