Tunisian operator audits network to improve services

One of Tunisia’s leading mobile operators has optimised its data network through an end-to-end data service and QoE (Quality of Experience) audit. Tunisiana has commissioned monitoring solutions provider Astellia to optimise its network for faster access to multimedia content, increased equipment efficiency and more reliable email and internet service delivery.

With 5.7 million subscribers and more than half of the market share, Tunisiana has been focused on the optimisation and monitoring of their networks for several years using Astellia’s probe-based solution.

The operator has witnessed a dramatic increase in popularity of internet-related services, and so has reinforced its data service offer with the release of new smartphones and electronic tablets as well as promotional offers such as ‘WapUp’.

The end-to-end data service and QoE audit involved placing probes provided by Astellia on strategic points of Tunisiana’s network, both on the access and the core parts. The analysis was performed in 3 stages:

  • comprehensively assessing the network performance and service quality as perceived by subscribers;
  • benchmarking these metrics versus regional reference KPIs; and
  • implementing recommendations to improve customer experience.

Amongst others, access time to data services was reduced by more than 30% by identifying delays due to packet loss at GGSN level. The push-mail application efficiency was improved by reconfiguring core network equipment and seamless service continuity was ensured for subscribers moving from cell to cell.

“Tunisiana has been using our solution for mobile network optimisation and troubleshooting for more than 10 years. This in-depth audit calling for Astellia’s expertise in data service and QoE represents another step accompanying them in the evolution towards the latest mobile network technology”, commented Jean-Philippe Larvol, Sales Director Africa for Astellia.

“This end-to-end audit provided us with a unique vision of data network and service performance from an end-user perspective”, said Hatem Mestiri, CTO at Tunisiana.
