Quality of service (QoS) as applied to the telecommunications industry is the overall performance of a telecommunications network, particularly the performance seen by the users (consumers), of the network.
To quantitatively measure quality of service several related aspects of the network service are often considered, such as supply time, fault repair time, call setup time, call drop ratio, response times for directory enquiry services, error rates, bandwidth, throughput, transmission delay, availability, jitter, etc.
Telecommunications Radiocommunications and Broadcasting Regulator (TRBR) developed its QoS Guideline after consultation with industry on an initially proposed Quality of Service Regulation. The purpose of the guideline is to establish a framework for the provision of information by service providers to inform the Government and the people of Vanuatu of the performance of their networks as well as to assist consumers with their selection of services and service providers.
The document may be considered for changing into a Regulation in accordance with section 7 (3) of the Telecommunications and Radiocommunications Regulation Act, if service providers do not follow the Guideline.
