Abstract:
The aim of this study is to investigate, measure and analyze the
Accuracy of billing systems in Sudanese telecommunication companies
(Op3, Op2, OP1 and Op4),by measuring the actual data (voice calls)
from the GSM/Modem and comparing it to the extracted data from the
billing systems within the telecom operators.
To study the problem and test the proposed solution the following
steps has been performed: Identifying call duration, Determining the
Price List of the call according to selected telecom company, Receiving
call by using ATA command to answer the call, Calculating the accurate
cost of call according to specified price and call duration, by
2multiplying the call duration in selected price to get the total cost of
call, Generating Reports which used to generate Actual reports from
the voice calls, price/cost/Quality
to make comparisons between
actual voice calls throw GSM/Modem and ordinary voice calls , throw
Billing Systems that telecommunication companies generated.
The thesis experiments
proved the accuracy of the billing system
inside OP1 network and outside OP1 network to Op3 telecom company,
but it is lacks some precision when calling from OP1 to Op2 telecom
company, also the results proved accuracy of billing system in Op2
telecom company when calling from Op2 to Op3 and OP1 telecom
companies (Off-Net), but it is lacks some precision when calling from
Op2 to Op2 (On-Net), and also the results proved accuracy of billing
system inside Op3 Telecom including On Net Calls when calling from
Op3 to Op3 and Off Net Calls when calling from Op3 to OP1telecom
and Op3 to Op2telecom
