PROTEI has successfully completed a comprehensive project to modernize the infrastructure elements of Chinguitel, the leading telecommunications operator in Mauritania. As one of the largest telecommunications service providers in the country, Chinguitel boasts a subscriber base of over 1.2 million, offering mobile services and broadband Internet access. Known for delivering high-quality services, Chinguitel continually seeks to innovate and enhance its offerings.
To improve subscriber services and accelerate time-to-market, Chinguitel decided to replace its outdated and inflexible billing system with a modern, converged solution tailored for the digital age. This upgrade involved not only the replacement of the billing system but also the integration of key adjacent service platforms, including SCP, SMSC, USSDC, Call Completion Suite, Service Builder, and Call Center.
A distinctive aspect of the project was the integration of the SCP with both the GSM and CDMA segments of Chinguitel’s network, which required the use of a specific protocol stack. Additionally, the project architecture featured a unified service creation environment that automates customer care services across various channels, such as USSD, IVR, and USSD-like services for CDMA subscribers.
The implemented solution is based on the PROTEI Service Builder, which significantly accelerates the development, implementation, and modernization of services through an intuitive visual environment for designing and managing both new and existing services. Furthermore, a notification system was deployed to facilitate bulk SMS campaigns targeting Chinguitel subscribers. These campaigns are occasionally launched to inform both Mauritanian (GSM segment) and Zaki (CDMA segment) subscribers about special offers, thereby stimulating the use of various operator services. Notably, the reporting structure for the subscription services units differed significantly from that of other customers, necessitating enhancements to the reporting systems for IVR, USSDC, and the Call Center.
