A novel algorithm for efficient spectrum management to optimise spectrum utilisation between two sharing UMTS cellular operators is presented and shown that proposed solution approach increases revenue of sharing operators without sacrificing the quality of service on either network.Abstract:
Dynamic spectrum management is a promising solution for network operators to efficiently utilise the limited radio spectrum and guarantee operator's profit by increasing capacity as well as generating more spectrum opportunities for opportunistic use. This paper presents a novel algorithm for efficient spectrum management to optimise spectrum utilisation between two sharing UMTS cellular operators. It is shown that proposed solution approach increases revenue of sharing operators without sacrificing the quality of service on either network. A multioperator UMTS simulation tool is also developed to evaluate the performance of proposed algorithm. The simulation results show that the proposed algorithm achieves high efficiency of spectrum utilisation and gains up to 33% can be achieved for both uniform and non-uniform distribution of traffic.read more

Dynamic Spectrum Management for Intercell Interference Coordination in LTE Networks Based on Traffic Patterns
TL;DR: This paper tackles the problem of intercell interference coordination from the self-organizing network (SON) viewpoint by optimizing fractional frequency reuse (FFR) and adapting to dynamic traffic maps and a traffic-based dynamic spectrum management (DSM) algorithm is proposed to reduce the call drop and block ratio (CDBR) and to improve the network throughput.

Dynamic inter-operator spectrum sharing for UMTS FDD with displaced cellular networks
TL;DR: The paper investigates the possibility for competing network operators to cooperate partially without operational information exchange and to share a block of UMTS carriers simultaneously to provide services and finds that the relative displacement of cooperating networks has a negative impact on the trunking gain given by the spectrum sharing mechanism.
