Abstract
Joint radio resource management (JRRM) mechanism helps to optimize the radio resource usage of heterogeneous wireless networks but the introduction of central new entity which manages the information of all networks in JRRM may require unbearable change to current network architecture. Aiming at easily integrating with existing and forthcoming heterogeneous wireless networks, this paper proposes a semi-distributed scheme without centralized entity, in which user terminal make decision on network selection through fuzzy neural network method based on local information and the selected network finishes the admission control to user terminal according to its actual resource condition. Our scheme is verified by the simulation in the UMTS/WLAN scenario and can effectively balance the load between the UMTS/WLAN networks while maintaining the level of blocking probability compared to traditional distributed WLAN-prefer algorithm.
