>> Study Group 2 : Operational aspects of service provision, networks and performance
Question 4/2 – 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.
Standardization of
service quality parameters and measures are needed for all services using
current networks and Next Generation Networks (NGN).
- Question
Considering
- That service quality of networks needs to be assessed as a total connection,
focusing on the end-to-end network service offered at all times;
- that there is a need to support service assessments by measurement of clearly
defined service and network parameters;
- that 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;
- that emerging customer/user applications on Next Generation Networks (NGN) have the
need for high-quality and seamless interworking;
- that 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;
- that increasingly operational and QoS aspects of security recommendations must be considered;
- that some alternative calling procedure may reduce significantly the service quality of networks;
- that customers/users expect distinct quality of service classes;
- that customer/user behavior associated with a service could have an impact on network performance and quality of service;
- that voice and other services will be offered on emerging network and access
technologies;
- that advanced routing methods will have an impact on how parameters are measured.
What new or revised Recommendations are required to ensure
that adequate network service quality can be provided to meet customers’/users’
expectations? For example, new
recommendations may be required for the emerging Next Generation Networks (NGN).
- Tasks
New and revised Recommendations are expected during the Study Period as reflected in the table
below, which will be updated on an on-going basis.
