網際網路上網路位址(IP)具有區域性,導致傳統的網路程式設計以指定固定的IP為導向。但目前蓬勃發展的可攜性裝置,會因人漫遊在不同的無線網路,而導致裝置的IP不停的改變。這讓傳統網路程式無法正常運作。有鑒於此,為了讓程序間的資料傳遞能支援移動性,我們設計了一個聊天系統,提供新的機制來達成無空隙溝通,使用者帶著通訊設備只要在無線網路的環境之下可隨時隨地、且沒有時間限制的溝通,甚至使用者沒攜帶通訊設備由一個地點移動到另一個地點時,只要在目的端有通訊設備就能持續溝通,不會造成訊息的遺失。
With the fast development of the Internet combining with the wireless network, communication way changes by adopting low-priced Internet communication manner. The assignment of Internet Protocol (IP) address to a host is fixed according the located area of this host. The property results that the conventional network programs been designed are based on fixed IP addresses. With the rapidly growth of the portable devices, a process with the device has high probability to surf on different wireless networks. Therefore, the address of a host will be changed according to the located subnets and the convention software is difficult to run normally on this environment. In this paper, we offer the new method that the communication among mobile subscribers do not stop when the subscribers surfs on Internet. Even the user without a communication equipment moves to another place, as long as to the new environment has the capability to connected to Internet, the users still acquire the communication service and will not lose the contents sent to them when they were located at the environment without Internet.
