The integration of existing cellular systems with new wireless access technologies, such as wireless LANs, has attracted considerable attention during the past few years. The challenges to be addressed include authentication, security, QoS support and mobility management. Efficient mobility management, and especially handover management, is considered as one of the major factors towards seamless provision of multimedia applications across networks of different technologies. A large number of

In order to evaluate these solutions, a more systematic categorization is needed. This survey gives an overview of the most recent handover management architectures for integrated WLAN/Cellular networks, focusing mainly on 802.11based WLANs and GPRS/UMTS cellular networks. The various proposals are categorized based on the point of system integration, their main characteristics are presented and their advantages and shortcomings are discussed in an overall evaluation section.
