In the current competitive world, Quality of Service (QoS) is becoming, jointly with cost, a key indicator in selling andbuying telecommunications services. At the same time, technology and liberalization trends are raising new types ofconcerns unknown with the Plain Old Telephony Services (POTS) using switched connections provided by a singlemonopoly supplier.
Nowadays, there are several standards describing QoS measurements but the questions of which indicators are to bemonitored and which values they should meet are still open. ETSI EG 202 009-1 proposes a methodology for theidentification of indicators relevant to the users that can be used either to monitor the QoS of Telecom services used bythe private customers or for a Service Level Agreement (SLA) between a business customer and a supplier ofTelecommunications services such as that proposed in ETSI EG 202 009-3 [i.22]. This part 3 gives guidelines on howto express explicit user’s QoS requirements, prioritize the indicators, establish a preferred value for each of theseindicators, while ETSI EG 202 009-2 [i.21] proposes QoS indicators for each service and each step of the CustomerRelationship Course.
The present document was written to make available to the providers and users of any kind of telecom services (legacynetwork based or IP network based services) a common basis for mutual understanding about quality of service. It aimsto assist users in identifying rationally their QoS requirements in terms of Service Level Objectives (SLO), helping theproviders to better meet them for their mutual benefit.
