Tektronix Unveils NET-GPRS 4.4 with New Statistics Application

8/26/2004 - Tektronix, Inc. (NYSE: TEK), a leading worldwide provider of test, measurement and monitoring instrumentation, announced the availability of a new statistics application (GbSTS) for its latest General Packet Radio Services (GPRS) monitoring system, NET-GPRS version 4.4. GbSTS in NET-GPRS version 4.4 provides new key performance indicators (KPIs), specialized statistical reporting, and additional features to extend NET-GPRS beyond network assurance to become a complete service assurance package.

In a GPRS system, data is transferred between the mobile station and an external packet data network. This approach uses packet switching that has been added to an existing GSM network, and enables mobile data services such as email, text messaging, and even Web browsing. Early generations of GPRS monitors approached troubleshooting from a network perspective, which is appropriate for finding problems but is not always sufficient to meet guaranteed quality of service. NET-GPRS version 4.4 with GbSTS essentially changes the nature of troubleshooting from network management to service management and will aid operators in their efforts to meet service level guarantees.

To do this, GbSTS introduces a variety of KPIs that address network and service levels. KPIs are structured to provide different views to mobile operators including Network View for network assurance, Traffic View for optimization, and Service View to control and verify the quality of each service delivered by the network. All KPIs are grouped within these areas and provide granularity per SGSN, PCUs and Cells.

For its effectiveness, NET-GPRS version 4.4 has been already selected by several operators, including Vodafone Italy for its GPRS test plant.

"Delivering data services such as email and internet browsing is still a relatively new challenge for network operators," said Alois Hauk, General Manager, Mobile Protocol Test, Tektronix. "NET-GPRS version 4.4 with GbSTS helps operators to understand whether problems are related to the network or to the services. The application provides extensive views, making it possible to analyze each service split per cell of the monitored network, thus discovering if weak areas exist. Customers will immediately be able to determine and control how services are delivered by their network and also determine which cells are not delivering the expected quality of service."

NET-GPRS version 4.4 runs on Tektronix' popular NET-X stationary monitoring platform delivering state of the art troubleshooting tools like end-to-end session trace, protocol analysis, real time status monitoring and network-wide deciphering with the ability to store virtually any information, without limitations.

Customers will be able to troubleshoot their network and services starting with the GbSTS, and if needed, can further explore for the root cause with NET-X procedure tracing. In addition, by using the procedure trace feature, customers can look back in time to reconstruct the protocol details of transactions and the path followed. Graphical tools help the user quickly locate problems in the flow of protocol messages across the network, through different protocol layers, and identify sources of QoS degradation. The result is faster response to subscriber complaints and more accurate assessment of the problem and potential solutions.
