Abstract:Heterogeneous network selection is a popular topic with the rapid development of telecommunication technologies. Literatures employed different ways for solving the issue with drawbacks more or less especially neglecting the user preference and using much subjective configurations. This paper proposes a user preference scheme including realtime or non-realtime pursuit, money and battery consumption concern and non-specific requirement. For front four modes, a technique for order preference by similarity to ideal solution based method with vote which reduces the subjectiveness is introduced. Then, a function-less and totally unsubjective method called directional distance function based data envelopment analysis method faces the non-specific requirement. Several examples test these two methods and the results support them.
