We develop a licensed shared access (LSA) concept based spectrum sharing method in the context of special applications such as public safety (PS), military and commercial radio systems. We focus on a system where PS has its own wireless network and is an LSA licensee of the spectrum, which gives the PS the possibility to gain additional spectrum dynamically. The aim is to help PS system prepare for the exponential wireless data growth in the next years. Especially interest is in how the network can be built securely and robustly against connection breaks and suggestion of key functionalities of different LSA system components. We simulate the spectrum sharing system to validate the proposed functionality and to study the system performance with different types of incumbents. Moreover, we study the system performance when the spectrum is reserved early. The results show that the method offers reliable LSA spectrum sharing in various conditions assuming that the system parameters are set properly. The paper gives guidelines to set these parameters.
