Slide 12: 10 Best Practices in LTE Testing
10 BEST PRACTICES IN LTE TESTING that you cannot afford to ignore… 12 Confidential © Tech Mahindra 2011
Slide 13: Right test strategy – This is where it starts
Best Practice # 1 Right test strategy – This is where it starts The Need LTE means different things to different stakeholders. Any assumption on protocol conformance or feature support could mean cost or schedule over runs. Unless the gory details are written down and shared with all stake holders,
Slide 14: LTE Test Lab: A Key investment not to be compromised on
Best Practice # 2 LTE Test Lab: A Key investment not to be compromised on The Need The overall LTE solution includes very large number of components from devices on one end and packet core at the other end. Validating the complete solution in a lab would ensure that the LTE roll out occurs in predic
Slide 15: Test Compliance with Customizable Simulators
Best Practice # 3 Test Compliance with Customizable Simulators The Need Real LTE equipment may be available or affordable and off-the-shelf LTE tools may not meet specific requirements for testing often holding up test progress. For certain test requirements such as compliance it is best to use tool
Slide 16: Minimize nasty surprises with pre-validated E2E Test Suites
Best Practice # 4 Minimize nasty surprises with pre-validated E2E Test Suites The Need With its associated technology complexity and interoperability the number of scenarios that need to be validated for LTE are extensive. Having a test suite for E2E scenarios defined by 3GPP both reduces the test c
Slide 17: Minimize manual errors with LTE Test Automation
Best Practice # 5 Minimize manual errors and accelerate time-to-market with LTE Test Automation The Need Multiple scenarios need to be revalidated upon each upgrade and for each new release of software from the vendors. LTE test automation can help both reduce the time for and the errors associated
Slide 18: Don't forget to extensively test the LTE user plane
Best Practice # 6 Don’t forget to extensively test the LTE user plane The Need LTE is all IP network and the user plane transports different types of IP payloads at line rate. As data is king and the data plane is where the rubber hits the road – ensure that it is tested extensively. The Best Practi
Slide 19: Backhaul validation – A must before LTE network trials
Best Practice # 7 Backhaul validation – A must before LTE network trials The Need The backhaul network needs to do all the heavy lifting to transport the high bandwidth of data delivered over the LTE air interface. Validation of this network is critical to ensure the quality of experience for the en
Slide 20: Validate network elements thoroughly in isolation first
Best Practice # 8 Validate network elements thoroughly in isolation first The Need All core elements HSS, MME, SGW , PGW and PCRF as well as access elements have a considerable amount of data that needs to be configured. Validate the configuration and functionality of each of these segments individu
Slide 21: Ensure that devices on the network are certified
Best Practice # 9 Ensure that devices on the network are certified The Need From an operator perspective, Device Certification strategy becomes highly important as the network should not take the blame for the device performance. For device vendors – pre-certifying their devices in accredited 3rd pa
Slide 22: Verify LTE USIM/USAT conformance and scalability
Best Practice # 10 Verify LTE USIM/USAT conformance and scalability The Need Test Coverage for the LTE UICC/USAT requirements needs to be specifically accounted for by service providers and device vendors. The Best Practice Benefits TSP USIM/USAT tests covers Scalable conformance tests for all H
Slide 23: Conclusion
Conclusion LTE as a technology is geared-up to provide high-bandwidth services for improved user experience and is destined to stay for over decades as a strong competitor for both developed and emerging markets As explored in this Webinar, testing both LTE equipment and services poses significant c
