Abstract
一種無線傳送/接收單元(WTRU)具有一相連的偏移無線網路控制器(D-RNC)與一相連的服務無線網路控制器(S-RNC)。該偏移無線網路控制器(D-RNC)發送一要求信息至該服務無線網路控制器(S-RNC),要求該偏移無線傳送/接收單元(WTRU)的量測。該服務無線網路控制器(S-RNC)接收該要求信息與發送一帶有此被要求量測的資訊信息至該偏移無線網路控制器(D-RNC),而該偏移無線網路控制器(D-RNC)則接收該資訊信息。
Description
本發明是有關無線通訊系統。特別是,本發明是有關此類系統中無線網路控制器間之資訊傳送。
第一圖顯示一無線通訊系統,此系統中所有的使用者皆藉由一無線網路控制器(RNC)20來管理。每個使用者,即無線傳送/接收單元(WTRU)24,與節點-B 221(Node-B 221)進行無線通訊。節點-Bs 221-222群組係由無線網路控制器(RNC)20所控制。
當WTRU 24移動時,WTRU 241、242在基地台與節點Bs 32、34之間進行交接機制。第二圖係顯示一WTRU 241、242從第一RNC 28管理的區域移動到第二RNC 26所管理的區域。WTRU 242被認定已經"偏移(drift)"至新的RNC區域,該RNC(第二個RNC)就被視為是偏移RNC(D-RNC)26。D-RNC 26具有並控制一節點-Bs 32,第一RNC則被視為服務無線網路控制器(S-RNC)28。傳統的RNCs(S-RNC 28和D-RNC 26)可透過RNC介面(IUR)互相進行一些資訊的通訊,在WTRU 242 "偏移"至D-RNC 26後,D-RNC 26會替"正在偏移"的WTRU 242執行一些功能,例如動態通道分配(DCA)、進入許可控制、排程以及RRM功能,S-RNC 28仍然會為"正在偏移"的WTRU 242執行其
他功能,例如換手機制的判斷以及WTRU下行通路量測資訊的收集。當WTRU 24不偏移時,例如第一圖所示,RNC 20管理WTRU 24執行S-RNC 28和D-RNC 26的功能。
在第三代無線技術統合計劃(3GPP)的R99、R4及R5的規格下,當WTRU241、242從S-RNC 28交遞至D-RNC 26時,胞元開始裝載且許多節點-B量測資訊會從S-RNC 28發送至D-RNC 26。然而,並沒有一個機制能從S-RNC 28傳送可信的資訊至D-RNC 26,例如WTRU量測資訊。
因此,在RNC之間能有更佳的點對點通訊是一件令人渴望的事。
一種偏移無線傳送/接收單元(WTRU)具有一相連的偏移無線網路控制器(D-RNC)與一相連的服務無線網路控制器(S-RNC)。偏移無線網路控制器(D-RNC)發送一要求信息至服務無線網路控制器(S-RNC)要求偏移WTRU的量測資訊,S-RNC接收此要求信息並發送一被要求的量測資訊信息至D-RNC,此D-RNC接收此資訊信息。

第一圖:顯示一無線網路控制器(RNC)操作一無線傳送/接收單元(WTRU)。
第二圖:顯示在無線網路控制器(RNCs)之間的一無線傳送/接收單元(WTRU)偏移。
第三圖:顯示在一較佳實施例中,點對點的資訊交換之方塊圖。
第四圖:顯示在一較佳實施例中,點對點的資訊交換之流程圖。
雖然較佳實施例是以第三代無線技術統合計劃(3GPP)之寬頻分碼多重存取(W-CDMA)規格來描述,但實施例亦應用在其他無線通訊系統。
未來,一種無線傳送/接收單元(WTRU)包含但不限制在使用者裝置、行動基地台、固接或移動用戶單位、呼叫器、或能於無線環境下操作的任何其他形式裝置。
第三圖是一"正在偏移"的WTRU 242在使用點對點資訊交換時,一S-RNC 40、一D-RNC 38及一IUR 36的簡易方塊流程圖。第四圖是點對點資訊交換的流程圖。S-RNC 40為"正在偏移"的WTRU 242執行例如交遞判斷和收集WTRU下行通路量測資訊的功能,D-RNC 38則為"正在偏移"的WTRU 242執行功能,例如動態通道分配(DCA)、進入許可控制、排程以及RRM等功能。
D-RNC 38具有一RRM 42,RRM 42為與D-RNC 38相連之胞元之WTRUs管理資源,D-RNC 38替"正在偏移"的WTRU242之胞元以及其他利用上行量測收集裝置44的胞元收集上行通路量測資訊,這些量測資訊在RRM 42可用來作為資源配置和管理之用途,RRM 42也具有可讓WTRUs執行S-RNC功能的資訊。
D-RNC 38已與RRM 42邏輯連結,當RRM 42要求"正在偏移"的WTRU242或一個群組或WTRUs之下行量測資訊,邏輯46啟動一WTRU量
測需求裝置48透過IUR36發送一訊息,即步驟60。
D-RNC 38可能會要求該資訊的樣本,包括下行通路公共控制物理信道(CCPCH)接收信號編碼功率(RSCP)、干擾信號編碼功率(ISCP)量測及/或流量量測。較佳地,D-RNC資訊要求信息不能要求WTRU242執行或送出量測,但D-RNC 38要求此類的量測資訊可即時被S-RNC 40所利用。
在IUR 36上的信號訊息(signaling message)允許任一D-RNC 38啟動與位在個別WTRU上、位在WTRU群組上或是在出現於一個或更多胞元中的WTRU上的S-RNCs之資訊交換,因此其並不假設其在一S-RNC中的角色。此過程較佳地並不是一個簡單的WTRU特有資訊之"轉遞(forwarding)",例如WTRU量測。較佳地,該D-RNC邏輯46通常對於所需的資訊型態做決定,縱使邏輯函數46可能藉控制RNC(C-RNC)來表現。一位於D-RNC 38中的邏輯函數46係決定是否以及何時其將需要量測以便自該S-RNC 40而被發送。例如,假使D-RNC 38偵測到超過一個門檻數或是百分比,例如10%,的WTRU是處於"偏移"模式,其典型地將會開始要求量測以便被發送。在一較佳實施中,由節點B介面(Iub/IUR)之第三代無線技術統合計劃(3GPP)標準所定義而存在的資訊元件以及標準化的WTRU量測/紀錄機制係被利用。
一較佳信息允許D-RNC 38在一特定時間間隔中對一特定"偏移"WTRU 242,或是對位在一特定胞元中的所有"偏移"WTRU,亦或是在特定時間間隔內對與S-RNC 40有關的胞元群組來請求量測。當擁有一特定S-RNC的許多WTRU處於"偏移"模式時,一種請求WTRU群組資訊的通信定義表是被渴望的。例如,一第一列車站(train station)係藉一第一RNC所支撐
而一第二列車站則是藉一第二RNC所支撐。搭上開始於該第一列車站而正離開該第二列車站之列車的所有WTRU可能具有該第一RNC,例如S-RNC 40,以及該第二RNC,例如D-RNC 38。在此通信定義表中,要求"偏移"WTRU群組中的WTRU資訊將減少了信息過量。然而,一具有被增大之信息過量(messaging overhead)的通信定義表,此過程在該處將僅允許每個WTRU之一單獨WTRU能被使用。
此訊息係被正在偏移的WTRU S-RNC 40所接收,步驟62。該S-RNC 40具有一WTRU量測收集裝置52。此WTRU量測收集裝置53儲存特定WTRU的下行通路量測。一WTRU量測回應裝置50透過IUR36發送一量測/資訊訊息至D-RNC38,步驟64。D-RNC RRM 42使用這些量測在它的資源分配與管理中,步驟66。透過IUR 36來轉換這些資料的一個好處是這些資料轉換將典型地非常快。
用以請求並轉換這些WTRU量測的一個較佳方式使用了無限網路子層應用部分(radio network sublayer application part,RNSAP)程序。無限網路子層應用部分(RNSAP)有四個基本程式單元。這些程式單元之一為"整體程序(Global Procedure)"程式單元。此程式單元包含在RNC間執行胞元階資訊交換訊息之發送的程序。例如,接收到的總寬頻功率,載入與全球定位系統(GPS)時序資訊係藉使用一共用量測訊息而被交換。
使用無限網路子層應用部分(RNSAP)整體程序而交換的資訊表單係被擴至允許較佳的RRM。特別地,此資訊有助於最初之訊號換手決定。例如,與換手至周圍RNC的偏差胞元有關的資訊將助於此種決定。在此被提及的第三代無線技術統合計劃(3GPP)系統中,使用整體程序程式單
元而交換的資訊與一特定WTRU或是WTRU群組並無關連。因此,其並不支持透過IUR 36來傳送WTRU資料的傳輸。較佳地,資訊應透過使用無限網路子層應用部分(RNSAP)程序之IUR 36而傳送,假使此種類比胞元資訊可獲自於S-RNC 40之中或是與D-RNC 38有關的RRM決定之中。
此種透過IUR 36之資訊交換係使得一D-RNC 38可自該S-RNC 40中請求WTRU量測資訊,並使得更多胞元資訊能在使用無限網路子層應用部分(RNSAP)整體程序組件單元的點RNC之間被交換。典型地,這些資訊的交換增大了在D-RNC 38中的RRM演算法(動態通道分配(DCA),容許控制(Admission Control),服務排程以及其他)之表現,其係由於WTRU量測的可利用性。增大的RRM,特別是動態通道分配(DCA),促進了在無線系統,例如第三代無線技術統合計劃(3GPP)之分時雙重劃分(time division duplex,TDD)模式,中之表現、效率以及堅實(robustness)。
