Abstract: The model has been designed to calculate mobile bandwidth saving using FMC Techniques. The model is based on the average time the subscribers spend at home/office, the number of fixed lines in a mobile cellular coverage area, the average traffic generated by each subscriber, etc. The number of mobile phone subscribers in India has already crossed 700 million by December 2010 and increasing at about 18-20 million subscribers per month. This phenomenal growth also has lead to poor quality of service with frequent call drop outs etc. due to heavy traffic congestion especially in urban areas. The problem is compounded further by the limited amount of spectrum available for mobile cellular networks. The adoption of emerging NGN techniques coupled with Fixed Mobile Convergence (FMC) could alleviate the problems to a large extent. The FMC concept for spectrum saving is based on the concept of utilization of an existing resource in the form of fixed telephone lines for diverting the traffic on mobile networks in scenarios where such diversion will not affect the user service requirements. The enabling technologies that can lead to FMC have also been identified from users perspective. A mathematical model has been developed to estimate the amount of spectrum that can be saved through FMC. Parametric analysis has been carried out with respect to the parameters which influence the spectrum saving. The model has been applied on real life networks to demonstrate the percentage of spectrum that can be saved. The spectrum thus saved can be used for increasing the number of mobile users without any addition to the existing mobile network infrastructure.
