IP Service Assurance Solutions for GSM/UMTS/HSPA Operators

GSM evolution technologies such as GPRS, EDGE, W-CDMA and HSPA, have significantly advanced the mobile operator’s capability to offer mobile broadband, IMS based services, multimedia services and to simplify operations. Integral to the mobile network evolution is the paradigm shift of the underlying network from TDM in GSM to all-IP packet core in UMTS and HSPA which necessitates deep insight into IP subscriber, service and network data.

nGenius Service Assurance Solution

NetScout’s nGenius Service Assurance Solution is a native IP solution and it provides detailed IP level insight, end-to-end visibility and assurance into the subscriber, network and service domains. This enables operators to manage the IP network transformation, to monetize, support the demand and growth for data, voice and video services. Key benefits of the nGenius solution are:

• Unified view with unprecedented access-to-core visibility (Gb, Gn, Gp and Gi interfaces)
• Predict and prevent service degradations (GTP, PDP, etc) and quickly resolve issues.
• Intuitive network and service troubleshooting workflows.
• Extensive back-in-time forensic analysis.
• Full visibility into significant revenue (Blackberry, iPhone) and over-the-top services.
• Detailed drill-down into control, data and user domains
• Broad support for UMTS and HSPA specific metrics (GTP, MIP, SCTP, PDP, etc.)

The nGenius Service Assurance Solution includes the elements identified in Figure 2. Each solution element plays a vital role to ensure comprehensive service, network and subscriber assurance.

nGenius IP Service Assurance Solution meets the needs of GSM/UMTS operators

The nGenius Solution provides complete visibility, from KPIs to flow data to packet details, into service metrics and statistical information gathered by monitoring all key access-to-core interfaces.

The nGenius Service Assurance Solution leverages intelligent Deep Packet Capture and inspection technology to deliver real-time service-level operational intelligence that spans from high level services, application and conversation flow information all the way down to actual packets. This enables UMTS/HSPA operators to improve network, subscriber and service monitoring and reduce time to repair.

Investment protection for HSPA+ and LTE migration

The flexible, service-oriented architecture of nGenius Service Assurance Solution enables UMTS/HSPA operators to leverage their investment in NetScout solutions for future services and networks as well. The nGenius Service Assurance Solution will simplify and assist UMTS and HSPA operators to migrate to HSPA+ and LTE while retaining their existing investment.
