    Abstract: 摘要 在未來的通訊趨勢將是朝向無線、寬頻的多樣化服務,IP與Telecommunication整合是必然的發展方向。隨著網際網路的興起,資訊流通更加快速;而行動通訊建設的完備,也使得行動用戶能夠隨時隨地享受溝通的樂趣。理想中的Mobile Internet則是結合網路服務與行動通訊,將可以同時滿足要求多樣化服務以及行動需求的使用者。 當行動網路是一個ALL-IP的環境時,就必須考慮到IP的移動性。Mobile IP是解決IP mobility的方案,但由於Mobile IP在運作上並沒有考慮到使用者繁複的移動行為,因此衍生出眾多micro-mobility的解決方案,其中具代表性的是Cellular IP。 而巨微細胞的行動通訊環境目前就已經存在,其配置的目的是解決容量不足的問題;未來巨微細胞的環境依然會繼續存在。當Cellular IP要適用在巨微細胞所佈置的行動通訊環境時,在進行行動管理時所考量的角度將會與目前的方式有所差異。本文所探討的範疇即是在以 Cellular IP為基礎架構,巨微細胞的行動環境;利用速度估計的方式來指派行動用戶的服務型態,並作適切的行動管理,以期減少快速使用者在漫遊時所必然遭遇的handoff,使每一個行動用戶都能的到良好的服務品質。 Global IP mobility solutions using protocols like Mobile IP(MIP) and SIP are not optimized to handle micro-mobility management, where low-latency handoffs are essential, to avoid inefficiencies and performance degradation. Host based routing (HBR) schemes, such as HAWAII, Cellular IP and MMP are one of two main classes of schemes for IP micromobility management, the other being hierarchical Mobile IP derived schemes. We look at performance issues of HBR schemes, both qualitatively and quantitatively. Two tier cellular system aim to provide adequate capacity for mobile users. In this paper we propose some mobility management schemes to handle mobility in an micro mobility domain which has two-tier cellular access network.
