近年來的網路通訊技術朝著ALL IP Network的方向發展,透過IP協定將大多數的通訊網路整合成一個可以彼此連通的通訊網路,提供使用者可以自由選擇不同無線通訊技術的裝置連結至網際網路。除此之外,新一代的無線通訊技術所能提供的連線頻寬及通訊品質也較以往的通訊技術來得更加優秀,因此有越來越多的使用者選擇使用無線通訊技術連結至網際網路,進而也改變了人們對於網路存取的習慣,除了不再被限制在固定的場所連結網路,更衍生出對於漫遊在不同無線網路之間需求。

如何確保連線不同無線網路之間漫遊中斷以及服務品質的保證則是目前最受關注的議題。本文提出一個階層式預先資源預留的機制,採用階層式行動網路區域註冊及預先資源預留策略。當行動節點在無線網路進行通訊時,透過階層式區域註冊,降低訊息交換及資源預留所造成的網路資源所造成的資源浪費,進而提高網路資源使用效率;並預先於即將可能進入的無線網路中進行預先資源預留,將在原網路的服務品質保證延續至新的網路之中,進而達到具服務品質保證的無接縫無線網路。
The network communication technology has been focus on "ALL IP Network" in this few years. Most communication networks have been integrated into the interconnected network via IP protocol. The new generation wireless technology can provide bandwidth and communication quality better than the previous. More and more users adopt wireless communication technology to connect to Internet. There would be no need to restrict users to stay in somewhere for communication requirements. People could roam anywhere, anytime and any device.

The most important issue is to ensure the smooth roaming and QoS guarantee in the different wireless networks. This paper has proposed a method of hierarchical advance resource reservations - (Seamless Wireless Resource Reservation Protocol, SW_RSVP). SW_RSVP utilized hierarchical region registration of mobile network and advance resource reservations policy. By hierarchical registering, the mobile nodes could communicate with each others. It will lower the cost of message exchange and resource reservations. A mobile node could reserve network resource before it accesses them. Also, the QoS guarantees can be extended to different networks to achieve a seamless wireless network environment.

Finally, we will give some bright simulation results to prove the SW_RSVP works well.
