Nexus8620 – Roaming Test System

Roaming Test System

The Nexus8620 Roaming Test System provides comprehensive and automated test features to monitor the "quality of service" for mobile services. Nexus8620 supports wireless network technologies such as

• GPRS
• GSM

Testing with real SIMcards

The Nexus8620 system uses real SIM cards from which mobile user profiles and parameters are taken. Comprehensive test campaigns for the following mobile services are available:

• International roaming
• Basic calls / supplementary services
• Data services (email, ftp, http)
• SMS / MMS services

The Nexus8620 system is a centralized and automated test solution in which the powerful scheduler enables multiple users to execute test campaigns in parallel. Service degradations or disruptions are noted via threshold alarms.

Key Benefits

• Active roaming monitoring of mobile users
• Service quality verification for voice and data services in GPRS and GSM networks
• Central SIMcard Server providing access to real SIM cards for easy subscriber management
• Threshold alarms for early detection of service disruption or service degradation
• Core interface access for maximized efficiency of test resources

Nexus8620 Description

The Nexus 8620 system is a unique network "quality of service" solution that monitors wireless services continuously and automatically. It checks for correct functionality and the required availability of GPRS and GSM services, verifying, for example, SMS, MMS and pre-paid services for both own and roaming-access end-customers.

Nexus8620 is unique in that it avoids use of the air interface and checks SIMcard validity in parallel with the service. Moreover, it generates threshold alarms so that you receive immediate notification of service disruption or degradation – often before a subscriber has even noticed that there is a problem.

A graphical scheduler controls the execution of test cases stored in the form of test files on the Test Control Unit. Its powerful resource management system allows multiple users to run test cases in parallel without any conflictions. Test results are presented in an easy to understand graphical format, optimized for fast fault localization with as much detail as possible.
