name: KQI
full_form: Key Quality Indicator
context: The introduction of Key Quality Indicators (KQIs), which reflect the end-to-end service performance and quality, could be used to better represent real customer experience. NGMN NGCOR has defined principles for KQIs which could be used to evaluate the customer experience for fixed and mobile networks. It is proposed that SA5 takes the responsibility to study how to standardize the related service KQIs providing a standardised common base for end-to-end measurements and to fulfil the NGCOR requirements. KQIs have also been defined by ETSI (TS 102.250), 3GPP SA4 (TR 26.944), NGMN (P-SERQU) and QuEST Forum should also be considered. The intention of KQI for the service experience is to try to reflect the customer experience with indicators reflecting them for example how many stalls occur while watching a movie, time delay before seeing the first screen of a movie. With this information, KQI could closely reflect the customer experience. The KPIs defined in the current specifications,
description: Key Quality Indicators (KQIs) are metrics used to evaluate and represent the end-to-end service performance and quality, reflecting real customer experiences in telecommunications networks.
explanation: The context explicitly mentions KQI as indicators that reflect customer experience, such as stalls while watching a movie or time delay before seeing the first screen. This aligns with the definition of Measurement, which includes network performance metrics like QoS (Quality of Service) and QoE (Quality of Experience).
