摘要


手持通訊設備近年來發展迅速,已從傳統通話、發送簡訊等簡單功能到目前能收發MAIL、上網查詢、下載資訊等,如今一般民眾多數已習慣透過手持通訊設備上網使用網路資源,並隨著無線網路應用的普及,人們對於利用手持設備行動上網以及多媒體傳輸的需求越來越殷切,但是多媒體應用日益廣泛的結果常造成手持設備的耗電量增加,且傳統網路連線方式會一直與基地台進行通訊,即使使用者並未使用網路服務,手持設備仍然會持續傳送訊號至基地台,此現象亦造成能源不必要的秏損。因此如何在有限的電池容量下,提出一有效省能策略就成為移動性的手持設備上非常重要的課題。 本研究藉由分析使用者之行為,針對不同行為模式來找出其主要特徵,將相同行為之使用者進行分群,根據其行為特徵分析佐以適合之省能模式,預期透過人性化省能模式的調整,在使用頻繁的時間區段內維持高品質的連線效率,並於使用者離峰時段進入睡眠機制,讓手持通訊設備在有限的電池容量下能夠延長其使用時間,在有限的能源條件下延長了行動裝置的使用時間,最後能夠減少不必要之能源消耗,達到省能模式最佳化的目的。

Handset devices have developed rapidly in recent years. The devices not only can be used in communicating, sending messages but also upgrade to connecting Net Mail, go surfing, and downloading information on the web. Most People are accustomed to going surfing by handset devices; hence with the popularization of wireless applications, they will be eager for going the Net and transmitting multimedia by handset devices. However, traditional web connection with base stations and general transmitting multimedia consume much power of the devices. Within the limited battery power, providing efficient strategy to conserve energy for handset devices becomes a very significant issue. The study analyzes different user’ behavioral patterns to find out main behavioral features, and then divides the users with the identical behavior into the groups to arrange their energy conservational model. The aim of this essay expects to maintain high connection efficiency within individual user’s rush hours, and translate normal state into sleeping state within user’s off peak hours. In sum, the conservational model can conserve power and extend the valid hours of the mobile devices.
