Wireless CS overview

The implementation of an all-IP infrastructure poses new challenges for wireless operators. It creates a more complex environment to maintain, as more signalling is involved when setting up and disconnecting network connections.

In the increasingly complex environment, where voice services needs to co-exist with new mobile data services, it is more important than ever to ensure the quality of service delivered to the end customer.

Although mobile data is projected to make up the majority of future revenue growth, voice still accounts for most of the revenue today. To be able to pro-actively manage end-to-end quality of experience and avoid churn, a well-implemented voice assurance system is vital.

Polystar's Service Assurance solution leverages signalling analysis and packet inspection technology to deliver real-time operational intelligence, spanning from high-level KPI & KQI metrics down to conversation flow information and actual packets.

By combining analysis of both signalling and voice (RTP) on a per-session basis, operators will be able to implement full customer- and service-aware performance monitoring of their networks. By analysing trends in the end-to-end quality, the system helps operators to pro-actively manage their QoS and to avoid churn.
