Quality of Service (QoS) refers to the capability of the service provider network to provide better service over various technologies like GSM, GPRS and UMTS. In Today's conditions of complex networks with various technologies & services under tough competition, maintaining a good service quality is becoming a real challenge and a differentiator at the same time.

Nowadays, generating Network KPIs and performance measures is not enough to represent the end-to-end quality and speed of service provided to the subscriber such as MMS or email, nor is it enough to simulate the subscriber experience.

Introducing UMTS to most of today's GSM operator networks, and offering both technologies on the same network is another dimension of complexity especially when it comes to interoperability between the two generations.

The job of Alkan Telecom is to help carriers and service providers to measure their network performance and to simulate their subscriber experience in their networks to pinpoint problems proactively and quickly, assuring the highest possible customer retention.

In this context, we have developed experiences over the years based on the network monitoring for signaling networks for all the technologies like GSM, GPRS, UMTS, SIGTRAN, and VoIP in addition to active testing and test call generation to ensure that new services and voice/content delivery are to the subscriber satisfaction.
