In a multi-operator shared network, an appropriate decision is needed for how much to share resources in order to maintain user satisfaction, while maximizing cooperation benefits. In this paper we investigate resource sharing in a three operators sharing system. The study focuses on the value of the sharing factor, which is the percentage of the operator resources dedicated for guest users access. Simulation results showed that resource reservation improves client satisfaction in terms of blocking rates, and the value of the sharing factor affects the achieved profits of the sharing operators. Besides, the best decision of the sharing factor and the pricing scenario depends on the capacity of the operator.
