對於跨國旅行者而言，國際行動漫遊享有使用原門號可避免漏接重要電話之優點，能直接在異國使用國際數據漫遊上網服務，是最便利的選擇，行動數據漫遊目前使用者的數據資料訊務皆須經過國際網路傳送回本籍網路，增加行動業者成本，推高終端定價，造成出國旅行者不願使用國際行動數據漫遊服務，成為沉默的漫遊者，使用者無法享有便利服務，業者則無法擴增營收。國際Wi-Fi漫遊，免去客戶在異國申請當地Wi-Fi付費帳號的麻煩，價格合理，沒有免費Wi-Fi公眾網路有嚴重資訊安全不足的疑慮，但涵蓋率較低及不可高速移動的網路特性，加上Wi-Fi標準制定未如行動網路事先完善考量商業運作機制之系統設計概念，以致消費者使用國際Wi-Fi漫遊時，可能因為Wi-Fi網路與行動網路自動切換而出現巨額帳單，或因未關閉自動連線設定產生高額收費等問題，導致客戶接受程度低，整體使用量無法提升，業者投入無法有相對產出。本文研究國際行動數據漫遊與國際Wi-Fi漫遊兩個跨國業者及兩種異質網路整合之實務問題，提出運用既有行動通訊協定確認使用者所在漫遊網，強化國際Wi-Fi漫遊認證，確保使用者在同一漫遊業者的行動與Wi-Fi網路，不會游移在不同Wi-Fi漫遊網，衍生過度收費之問題，以及強化終端設備功能與系統面服務分流之Local Break Out解決方案，深度結合兩個國際業者兩種異質網路[1]的國際數據漫遊服務，降低行動業者的國際傳輸成本，以吸引更多使用者採用國際數據漫遊服務，搭配優化計費機制與服務流程，讓使用者及業者擁有更優質的國際數據漫遊服務與發展空間。
The most convenient way to obtain data services across borders to world travelers is through international mobile roaming from current mobile operators. Nevertheless, all international data roaming services requires home routed traffic, which increases operating costs at mobile operators, burdens the terminal prices, and eventually forces users to become silent roamers; not using roaming services from current mobile operators. In the other hand, international Wi-Fi roaming, unlike typical free public Wi-Fi which has security issues, suffers from limited range in services, bill shock situations from auto-switching between mobile and Wi-Fi networks, and over charges from users forgetting to turn off Wi-Fi automatic connection setting with EAP-SIM authentication, results in customers less willingness to use. This thesis aims to discuss practical issues from international mobile data roaming and international Wi-Fi roaming services in heterogeneous network integration. Actions discussed in this thesis includes combing international data roaming in two heterogeneous networks from two foreign internet providers, using mobile networks to authenticate Wi-Fi roaming to eliminate over charges, providing Local Break Out solutions in terminal device features and system-side services, fusing mobile with Wi-Fi networks to reduce cost, and upgrades in billings and service processes. Solutions above may give operators opportunities to offer clients higher quality in services and more room for development in the future.
