5.1 Requirements for the Reconfiguration Process

5.1.1 System Aspects

TRUST concluded that a distributed processing environment and configuration management are necessary to support seamless service provision and scalable Quality of Service (QoS), involving the usage of smart devices.

Analysis of the needs and regulatory issues reveals a mapping of requirements and constraints onto a set of key system support functions [1], namely the creation and provision of services over converging networks and different radio access modes, user environment management and distributed processing framework supported by appropriate middleware(s) and radio reconfiguration control. These functions constitute a core of operative procedures grouped in the following system aspects. Advanced Spectrum-Sharing Techniques

Current spectrum allocations do not exploit the flexibility of reconfigurable radio concepts. This is because they are intended for radio systems with rigidly defined frequency specifications that would not be able to share ...
