h experience. Typically, a wide range of applications is operated over the DUT to identify issues that occur in mixed traffic scenarios. Examples include: throughput centric applications. Traffic generators emulating continued high-throughput attach/detach scenarios; set up, tear down, and user of dual-/multicarrier configurations; nontypical use cases such as conference calls and emergency calls; combined traffic use cases where SMS, voice/video calls are combined with high- throughput HTTP traffic; Core Network Link recovery with Link Make/Link Break configuration; combined use of IPv4/IPv6; and exercises to the RRC state machines with idle/connected, handover, and DRX configurations. Cell performance Related to the RF and algorithmic performance of the RAN components, these tests confirm the performance of the deployed RAN combining RU and DU components. Examples include: Cell coverage and capacity. Overall range (distance) covered by the cell and capacity (in terms of user count and throughput) in various deployments scenarios. Cell coverage can include multicell deployments that incur intercell interference. Chapter 10 Interoperability and test 343 Spectral efficiency. As a function of distance to the cell center. Mobility. Ensuring handover, Doppler, and other mobility-related performance aspects are covered. White box testing Aspects of performance analysis have been discussed previously in Chapter 9, Software Performance. Here we summarize how we take the "design-for-performance" mantra from system integration and test perspective. An example of a development flow that includes performance targets is shown in Fig. 10-8. The development flow includes these following phases: Use Case Performance Calculator Hardware/BSP Software Optional: System Performance Targets Performance Targets Performance Model Hardware + BSP Performance Target Implementation Report Hardware/BSP Software (3rd party) Performance Statement of Work Benchmarks Software Implementation Software Performance Analysis and Optimization System
