摘要

第三代行動通訊網路(3G)的封包交換服務能提供較廣大的服務範圍，但速率相較是比較慢，而無線區域網路(WLAN)則是擁有較快的資料傳輸速度，但服務的涵蓋範圍相小，兩者在功能上具有互補的作用。
隨著科技的進步，提供行動用戶在異質網路間進行漫遊是通信產業一致的目標。當考慮到漫遊服務時，如何降低在切換網路時所產生的交遞延遲(handover latency)是一大挑戰，再者，當使用者移動速度太快而使得行動用戶託管位址(care-of-address)頻頻更換，將會導致Mobile IPv6網路外地代理器(foreign agent)轉遞訊息失敗而造成行通訊中斷。
本論文探討行動終端機使用於無線IPv6網路在WLAN與3GPP異質網路間交遞的問題，並提出一交遞管理機制來降低交遞延遲及減少不正確託管位址所造成的通訊中斷情形。

Third generation(3G) personal wireless communication networks,provide wide range but low data rate services, while the wireless local area networks(WLAN) provide limited range but high data rate services. Thus, 3G and WLAN are complementary in the services their provide. As a consequence of progress in technology, a common goal of the telecommunication industry is to provide service for mobile users to roam among heterogeneous networks. As far as the roaming service is concerned, how to reduce the handover latency is a big challenge.
Moreover, when the mobile nodes are fast moving, the care-of address is frequently changed. As a result, the foreign agents in the mobile IPv6 networks can not forward the packets to the care-of-address of the mobile nodes currently used. In turn, communications interrupt may occur. This these studies the problems of the mobile nodes in wireless mobile IPv6 networks switching among WLAN and 3G heterogeneous networks. We propose a mobility management mechanism to reduce the handover latency and the probability of communication interruption due to incorrect care-of address
