Enhanced service availability and resource utilisation by means of composite radio systems management

This paper builds on the assumption that in the fourth generation (4G) wireless system context Universal Mobile Telecommunications System (UMTS), mobile broadband systems (MBS) and digital broadcasting systems (DBS) can be three co-operating components that enable wireless access to IP-based services. Managing the resources of this powerful infrastructure in an aggregate manner and multi-operator scenario is a complex task. This paper presents an approach to the overall UMTS, MBS and DBS network and service management problem. Key points addressed are the development of open interfaces with service provider mechanisms and the heterogeneous managed infrastructure, performance monitoring, joint optimization of the UMTS, MBS and DBS resources in accordance with the service provider requests and the changing with time environment conditions. The architecture of a corresponding UMTS, MBS and DBS network and service management platform is presented, in terms of logical blocks, implementation options and validation approach
