M244657 9、創作說明（l) a本創作係關於通用行動電信系統（UMTS)，更特別地 =:本創作係為關於無線區域網路（WLAN)及通用行動電 信系統（UMTS )間之緊密互作系統。 創作先前技術背景 存在著一個需求，即提供無線區域網路（WLAN)及通 用行動電信系統（UMTS)間緊密互作之系統架構及具有能 支援下述之架構： 於兩系統間之交接；
當終端在兩系統間交接時，通話管理及連接；以及 在兩系統間鬆散互相作用之國際漫遊通信定義表。 創作内容 WLAN及UMTS技術係有效地相結合，以相互作用及支持 一緊密互作通信定義表。UMTS之Iur介面係被用於無損失 的交接，行動網際協定（IP )則被利用於通信定義表管理 及連接’而DIAMETER通訊協定訊號則被用於認證及會計。 實施方式

在WIP-GW 30和PLMN 12的用戶客服20之間具有一行動 網際協定（MIP)界面。WIP-GW30結合行動網際協定外部客 服與數種無線網路控制（RNC)功能，WIP-GW 30對於PLMN12 來說像是一外部客服、但對於AP來說則像是一無線區域網 路控制器（RNC)，輸入的資料穿過PLMN(用戶客服）和WLAN (WIP-GW)30之間（以輸入資料線38表示），輸出的資料則直 接從WIP-GW30流向網際網路4〇(以輸出網際協定資料線42 表示）。 PLMN1 2藉由使用HSS/HLR1 4以提供認證與訂購管理的服
