Question 12

Operational aspects of telecommunication network service quality

(Continuation of Question 12/12 - Operational aspects of telecommunication network service quality)

Motivation
It is essential to specify network service quality parameters to enable telecommunication services to be offered to customers/users in order to satisfy customers'/users' quality of service expectations. These parameters relate to both implementation and ongoing use of the service. Service quality is also related to all aspects of network assessment and management. Service quality of networks needs to be assessed as a total connection, focusing on the end-to-end network service offered at all times. Service quality parameters are required in order to meet customers'/users' expectation of a service, and related network performance parameters should relate to service quality parameters. Network providers must plan, dimension and operate their networks to parameters which will ensure that services offered to customers/users meet the latter's quality of service expectations.
