Ensuring seamless and reliable switching across different constituent technologies is the basic requirement of heterogeneous wireless networks. IEEE 802.21 standard is recommended for 4G networks for coordinating among different mobile network for better services. Still, there exists a scope of further improving its performance by introducing the fuzzy logic concepts in it. The paper aims in this direction where a fuzzy interface system is designed using four different parameters viz. speed of mobile terminal, available bandwidth, received signal strength and number of users.
