Given the growing world trend towards IP-based multimedia communications and the desire for every country to introduce its own native and customized model, proper evaluation of IP- based equipment for final type-approval is a major issue for the regulatory bodies. NGSTAP's objective is to develop a central and reference platform to accommodate all types of (or a variety of) evaluation scenarios. Test operators affiliated to different entities including government organizations, industry, research institutes, etc. can be connected to the platform and create their desired test procedures. This versatile reference platform is beneficial to the next generation system developers, importers and operators to enable them to achieve the highest quality of service.
NGSTAP is a type approval system that can be employed for performance and functional testing. It is a service oriented platform which finds application in test and type approval projects to develop some tests independently and in parallel. This platform consists of various modules for definition, creation, running, monitoring and reporting of the different test scenarios and has been designed based on IMS model and with a look to the future.
NGSTAP architecture has been designed with a service oriented approach which offers services for test scenario design, test scenario creation, test scenario run and preparation of reports. Test scenarios are protocol independent and system runs them according to the selected protocol. The following are the main technical specifications can be mentioned in this regards:
- Call related test with different protocols including SIP, H.248, RTP & SIGTRAN.
- Protocol independent design & creation of test scenarios
- Internet based running & online monitoring of all test operations
- 3rd Party software design using web service
- Extendable & scalable hardware & software to achieve its objective as a high performance system
- Equipped with SIP Tester, Reporter, Logger, Admin & Script Manager software.
