Abstract

This paper presents an evaluation of a radio level QoS management scheme developed to ensure the maintenance of QoS contracts. The concept of QoS contract is defined as the specification of the quality requirement for various types of services. According to the contracted QoS, a dynamic bearer selection is performed to adapt the link to the channel quality variations. Terrestrial Trunked Radio system (TETRA) presents itself as a suitable platform for illustrating the concept of QoS contract. This arises from its feature-rich bearer services that support data and voice with varying levels of error protection. The generic QoS management scheme presented in this paper has been applied to a private mobile radio system but it also represents an appropriate platform for multi-vendor, multi-technology and multimedia environments such as those found with 3G systems.
