Acess Network Selection Method Using Multi-Criteria Decision Making In Mobile Heterogeneous Network

摘要

An access network selection system and method using a fuzzy multi-criteria decision making method under a heterogeneous network system are provided. With such a system and method, a subscriber selectively accesses an access network having advantageous communication quality and cost according to transmission environment and service characteristics so that mobility capability is increased due to effective utilization of radio resources and traffic division of heterogeneous access networks. In addition, an optimum access network can be selected using a membership function and a decision making function evaluating access network selection parameters for multi criteria decision-making. Therefore, the access network selection method using fuzzy multi-criteria decision making can ensure mobility and access network options for a subscriber and ensure effective management of a wireless infrastructure resource to a provider under a heterogeneous network environment.
