UMTS900 deployment with different call handling strategies

The target of this paper is to investigate different traffic handling strategies to increase the capacity of the network. Impact of deploying UMTS900 with other GSM900/1800 and UMTS2100 layer was also observed in terms of capacity of the network. Number of mobile users is increasing enormously, and it is expected that the demand for data services and different kind of multimedia services will grow with accelerated pace. UMTS2100 has been deployed to meet the requirement of data services. But due to higher frequency band of operation, signals at higher frequencies experience more path loss. Therefore, to provide better coverage to indoor data users more sites of UMTS2100 are required. UMTS900 deployment provides the solution for high deployment cost, and it provides the better coverage as compared to UMTS2100. The deployment of UMTS900 as an overlay with UMTS2100 also helps in enhancing the network capacity, both for the voice traffic and data traffic. A position and service based call handling scheme is proposed in this paper. Results of this paper show that by adopting proposed traffic handling strategy, capacity of the network can be increased.
