Abstract—It has been widely agreed that there will be a coexistence of different radio access technologies in fourth generation communication networks. So there will be a problem of choosing the best access network at a particular time. The selection of the best access network will depend on a number of factors. This work aims to take into account their influence in the selection of the network using a Game theoretical modeling to solve the network selection problem. The paper introduces the concepts of Strategy Space, Quality Points in the Game theoretical context and gives a mathematical mechanism for network selection. Finally it is shown that only the best network serves the service request of the user.

Index Terms—4G communication networks, network selection, Game Theory, quality points, strategy space, weighting factors.
