WLC05-2: An Economic-Driven Joint Radio Resource Management with User Profile Differentiation in a Beyond 3G Cognitive Network

This paper proposes a new joint radio resource management (JRRM) strategy which, as a difference from previous works in the literature, introduces economic and user differentiation concepts. This economic-driven algorithm is based on guaranteeing a certain user acceptance of a given service, combining both the economic and technical dimensions, while at the same time increasing the operator revenue. Two user profiles with different needs are considered, namely consumer and business users, and it is shown that the needs of both profiles can be met by means of the proposed framework. Three implementations of the proposed JRRM are compared. Two of them are based on a user-centric approach, whereas the third implementation falls into the joint user-centric and network-centric category aiming at maximizing the operator revenue while maintaining the user satisfaction at a target contracted value. In this case, particular attention is paid to business users and to strategies based on resource reservation to improve their utility as well as the operator revenue.
