Description

M241897 創作說明（1) 曰本創作係/關於通用行動電信系統（UMTS )，更特別地 是’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。 新型背景 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。 新型内容 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（I p )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 第一圖顯示一系統架構1 0，其包括一公共區域行動網 路（PLMN) 12。其中公共區域行動網路12係包含用戶位置登 記/用戶訂購伺服器（HLR/HSS)14、認證授權及會計用戶設 備（AAAH)16、計費通訊閘功能（CGF)18、用戶客服20以及 整合封包式無線服務支援節點（GGSN) 22。
M241897 四、創作說明（2) 無線區域網路網際協定通訊閘（WLAN IP GW)，也就是 WIP-GW 30，在結合防火牆後，可利用兩個AP建立起信號 及資料界面；例如AP 32和34。使用者設備（UE) 36以雙模 態的WLAN/UMTS UE較好。 系統中之資料處理程序如下：
在WIP-GW 30和PLMN 12的用戶客服20之間具有一行動 網際協定（Μ I P )界面。WI P - G W 3 0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ΑΡ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11?-6¥30流向網際網路40(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 務，DIAMETER是一種網際協定網路中處理授權、認證及會 計功能的網際主協定，在本結構中DIAMETER的使用使得以 網際協定為基礎的認證、授權及會計（A A A )程序能夠在 WIP-GW和PLMN之間正常運作。由於PLMN原本即為一種UMTS 網路，所以提供認證與授權程序的節點是HSS/HLR，而提 供會計功能的PLMN節點是計費通訊閘功能（CGF)。HSS/HLR 和CGF提供UMTS程序及信號以幫助這些功能運作，AAAH提 供以網際協定為基礎的AAA程序和與其相對應的UMTS程序 之間信號的内部工作，使得輸入或輸出於HSS/HLR和CGF的 AAA功能也能在無線區域網路系統中運作。同樣地，μ I p提
第7頁 M241897 四、創作說明（3) 供網際協定網路中的行動管理程序，在一個U Μ T S網路中， 封包轉換資料服務的行動管理程序係由GGSN所處理。本結 構中的用戶客服針對GGSN提供介於ΜΙΡ程序（於WIP-GW和用 戶客服間運作）以及UMTS行動應用部份（MAP)介面之間的内 部運作，MIP/DIAMETER信號流自WIP-GW30輸出後，途經 AAA外部（AAAF)功能44以及AAA用戶（AAAH)功能16，最後輸 入用戶客服20。而MIP登錄信息則是被納入DIAMETER信號 中並穿過無線連結48。 AAAH16針對HLR/HSS14藉由行動應用部份（MAP)(鍺介 面）於DIAMETER之内部運作，使得HSS/HLR用於認證之運作 正常。 AAAH16作為使用GPRS穿隧協定（GTP)(藉由鎵介面）的 P L Μ N什費通訊閘功能（C G F ) 1 8之介面，使得p l Μ N收費伺服 器之運作正常。 ' 無線區域網路和UMTS PLMN1 2之間的通話連續性可藉由 使用MIP(WIP-GW30和用戶客服20之間）和GTPC用戶完服？η 和GG㈣之間)而獲得，用戶客服2。提供兩』== 内部運作’通話連續性可確保使用者在存取點（Access Point，例如32及34)之間和UMTS及WLAN網路之間移動時， 其通话及網際協定位址皆能保持不變。而更為進步的是， 當使用者在各網路間移動時，GGSN22之運作正如^通^資 料的錨點（Anchor Point)。舉例來說，在結構1〇中，如果 使用者如第二圖所示地，自無線區域網路^動到UMTS網路 時（UMTS Access NW50)，使用者的通話位置在GGSN22中仍
M241897 四、創作說明（4) 然是固定的，且在移動當中亦能夠因此而保持。當位於 UMTS Access NW50時，使用者設備36係藉由pLMN中的UMTS 無線存取網路（RAN)和伺服GPRS支援節點（SGSN)元件52而 月匕與具錫點的G G S N 2 2溝通。無線區域網路和υ μ τ S P L Μ N之 間的移轉係藉由Iur介面（以46表示）所完成，而wip_Gw支 援自UMTS的IUr界面46至UMTS RAN内的無線網路控制器 (RNC)的運作。
