This document presents the TRIANGLE Project experience with HSBooster.eu services The TRIANGLE Project has refined its findings to create a focused framework that captured the interest of ITU-T Q17/12, leading to the Y.TestBed standardisation initiative. This initiative presented a structured testbed setup and methodology to evaluate the Quality of Experience (QoE) of multiple 5G and beyond mobile use cases. The Y.TestBed Recommendation offered a calibrated, automated testbed and testing methodology designed to deliver consistent, repeatable results using commercial devices and applications, aiming at making results more valuable by mimicking the setup of a real user. TRIANGLE’s team has launched the Y.TestBed work item within ITU-T SG12 (Q17/12), but it faced challenges due to limited experience in standard writing. Through HSbooster, TRIANGLE aimed to receive expert feedback and guidance to ensure their contributions meet ITU-T standards and build the team’s expertise in standardisation for future initiatives.
