9.1 Introduction

Reconfigurable radio systems are expected to play a critical role in the area of mobile/wireless communications by increasing flexibility, reducing deployment as well as operation and maintenance costs, creating new business opportunities and employment, facilitating enhancement and personalisation, etc. [1].

In order to support fast reconfiguration or intersystem handover and the related mode negotiation procedure among heterogeneous networks, the co-operation between terminal and network should be highlighted. One important key of this co-operation is the information (user/terminal/service/network profile) needed by the mode negotiation and radio resource management for intersystem handover or any other adaptations. This information or profile data describes the capability of terminals, service, network and user preferences and presents an important decisive element in adaptation, such as intersystem handover decisions.

Two key features should be considered for mode switching or intersystem handover:

1. The database for system deployment supporting intersystem handover between coupled Radio Access Technology (RAT) sub-networks. The database can be organised as a table for storing network topology,
2. The management and storage of terminal (user/service) profile data in Radio Access Networks (RANs) and Cove Networks (CNs) depending ...
