Description

1308827 ’九、發明說明: 【發明所屬之技術領域】 本發明係指一種用於一無線通訊系統查詢資料傳輸狀況的方 法及裝置’尤指一種可避免一傳輸端無法成功執行查詢一接收端 或不必要查詢該接收端的方法及使用該方法之袭置。 鲁 【先前技術】 隨著資訊時代的來臨,行動語音、數據通訊與各種行動服務 的需求曰益增加,習知的行動通訊系統,已面臨通訊頻道不敷使 用與傳輸速率不足的瓶頸。因此,可提供更高頻譜使用率、更高 迷率傳輸服務的第三代行動通訊應運而生。相較於現有第二代行 動通訊技術,帛三代獅舰最縣的差異在於_寬頻劃碼多 •工接取(Wideband Code Division Multiple Access,WCDMA )的無 線接取方式,其係用以提供高度頻譜利用效率、無遠弗屆的覆蓋 率及高品質、高速率的多媒體資料傳輸,同時更能同時滿足各種 不同的QoS服務要求,提供具彈性的多樣化雙向傳輸服務,並提 供較佳的通訊品質,有效降低通訊中斷率。 第二代行動通訊系統可提供不同的傳輸品質等級,並可依據 不同的傳輸品質要求’操作於不同的模式,如:透通模式 • (τ麵p職tMode,TM)、非確認模式(Unadm()wiedgedM〇de, 5 1308827 觀)、確認模式(AcknowledgedMode,AM)。透通模式適用於 對即時傳輸要求較高的服務,非確認模式適用於對即時傳輸及封 包次序皆有要求的服務,而確認模式則適用於對即時傳輸要求不 高’但資料正確性要求很高的服務。 在確認模式中,為了提高資料正確性,傳輸端與接收端的無 線鏈結控制(Radio Link Control,RLC)層會適時地啟動—狀態回 •報流程’由傳輸端「查詢」(Poll)接收端’以要求接收端傳輸一 狀態回報單元或—爽帶式(Piggybacked)狀態喃單元。傳輸端 則根據接收端輸出的狀態回報單元,執行後續運作。當傳輸端查 詢接收端時,傳輪端選擇一協定資料單元(Pr〇t〇c〇mataUnit), 將該協灯料單元的查触元(PdlingBit)設定為啟動㈠), 從而提示接收端輸出狀態回報單元。關於習知技術選擇用來查詢 (即用來攜帶已啟動之查詢位元)的協定㈣單元的方法,請參 籲考以下說明。根據第三代無線行動通訊的技術規範,當查詢被觸 發,而查询未被禁止時,且傳輸端中無協定資料單元被安排傳輸 或重傳’則選擇-已傳送但尚未被確認的協定資料單元來查詢接 收端。此時,若傳輸端的傳輸窗大小大於或等於2048,則選擇具 有序號等於傳輸端下一新傳之協定資料單元的序號減丨之協定資 料單元,並啟動所選之協定資料單元的輪詢位元後,安排重傳。 相反地,若傳輸端的傳輸窗大小小於2048,則習知技術可選擇具 、有序號等於傳輸端下一新傳之協定資料單元的序號減1之協定資 料單元,或選擇-尚未被確認的協定資料單元,再啟動所選之協 1308827 定資料單元的查詢位元後,安排重傳。 透過查詢’傳輸端可要求接收端輸出狀態回報單元,以判斷 接收端接收協定資料單元的狀況,從而決定是否有協定資料單元 要重傳以維持資料的正確性。因此,有效選擇用來查詢的協定資 料單元就顯得相當重要。 另一方面,在第三代無線行動通訊系統中,若一伺服資料單 兀(Service Data Unit)已被傳輸端重傳一預設次數,或在一預設 時間内,傳輸端始終未收到接收端對該伺服資料單元的確認收訖 訊號。為了提高傳輸效率,傳輸端會(以外顯發訊式流程)刪除 該竹服為料單元並輸出一移動接收窗複合搁位(Move Receiving Window Super Field)至接收端。當傳輸端刪除伺服資料單元後, 攜帶該词服資料單元及該伺服資料單元之長度指示攔位的協定資 料單元亦會被刪除。如此一來,傳輸端可提高傳輸效率,以減少 不必要的重傳協定資料單元或等待確認訊號所浪費的系統資源。 因此’在某些情況下,所有存於傳輸端之緩衝器的協定資料 單元可能在被確認之前就被刪除’此時’選擇查詢的協定資料單 το就會發生錯誤。舉例來說,若傳輸端的傳輸窗大小為4,且傳輸 端已傳送序號為〇、1、2、3的協定資料單元。若重傳序號為0、1、 2、3的協定資料單元已傳過許多次或等待確認訊號過久,使得刪 除祠服資料單元的流程被啟動,因此序號為〇、1、2、3的協定資 1308827 料早7L皆由傳輸端的緩衝刪除,_輸端的缓·中無任何 協疋貝料單7G。此時’若無協定資料單擔安排傳輸,而查詢未 被禁止’且查詢被觸發。由於傳輸端的傳輸窗大小小於2048,傳 輸端可選擇具有序鮮於傳輪端下—新傳之協定㈣單元的序說 (-4)減1之協定資料單元(即序號為3的協定資料單元),或選 擇一尚未被確認的協定資料單元(即序號為G小2、3的任—協 定資料單it),作為絲查詢_定資料單元。然而,由於傳輪端 =緩=¾巾無任何協定資料單元,因此傳輸端無法成功選擇協定 貝料單7L來查搞造成錯誤。實際上,在此情形下,無論接收端 2態回報單讀顯示㈣訊為何,由於序號為G小2、3的協 疋貝料單70皆由傳輸端的緩衝器中刪除,傳輸端會直接將下-新 傳之財資解元騎應的賴設定為4,目此根林需要查詢。 次抵Γ言之,在胸繪中,當所有存於傳輸端之緩衝器的協定 ^早疋在被確認之前就被刪除時’傳輸端無法成功執行查詢接 作’使得_生錯誤。實際上,在輯形下,傳輸端 ⑥要查詢接收端’如此多餘的運作降低了整體傳輸效率, 展費系統資源。 【發明内容】 統二傳 1308827 本發W#露-麵於-錄賴祕查詢㈣傳輸狀況的方 法’其包含有:於-傳輪端無封包被安排傳輪或重傳,且該傳輸 端查詢-接收端之流程被觸發,且該傳輪端查詢該接收端之流程 未截止時,判_傳輸敵_ii巾是科已㈣輪、未被刪 除、且尚未被確認的封包;以及於該傳輸端之緩衝器中有已被傳 輸、未被刪除、且尚未被確認的封包時,選擇—封包來查詢該接 • 收端,安排重傳該被選擇的封包。 本發明另揭露-種用於一無線通訊系統之無線通訊傳輸裝 置用以正確查5旬資料傳輸狀況,該無線通訊傳輸裝置包含有一 硬體電路’用來實現該無線通訊傳輸裝置的功能,一處理器,用 來執行-程式碼以操控該硬體電路,以及一儲存記憶體,用來儲 存=程式碼。姉式碼巾包含有:_無線通訊傳輸裝置無封包 鲁被安排傳輸或重傳’且該無線通訊傳輸褒置查詢一接收端之流程 被觸發,且忒無線通訊傳輸裝置查詢該接收端之流程未被禁止 時,判斷該無線通訊傳輸裝置之缓衝器中是否有已被傳輸、未被 刪除、且尚未被確認的封包;以及於該無線通訊傳輸裝置之緩衝 裔中有已被傳輸、未被刪除、且尚未被確認的封包時,選擇一封 包來查詢該接收端,安排重傳該被選擇的封包。 【實施方式】 1308827 清參考第2 ®,第2圖為用於-無線通訊錢之無線通訊傳 輸裝置(傳輸端;)200之功能方塊圖,該無線通訊系統可以是一第 三代行動通訊系統。為求簡潔,第2圖衡出無線通訊傳輸裝置 200之—輪入裝置2〇2、一輸出裝置2〇4、一控制電路2恥、一中 央處理器208、-儲存裝置210、-程式碼212、及一收發器214。 在無線通訊傳輸裝置20〇中,控制電路206透過中央處理器2〇8 執行儲存於儲存裝置21G中雜式碼212,從而控制無線通訊傳輸 ♦裝置200之運作,並可透過輸入裝置2〇2接收使用者輸入之訊號, 或透過輸出裝置204輸出訊號。收發器214用以接收或發送無線 訊號,將所接收之訊號傳送至控制電路2〇6,或將控制電路施 所產生之訊號後以無線電方式輸出。換言之,以通訊協定之架構 而δ,收發器214可視為第-層的一部分,而控制電路2〇6則用 來實現第二層及第三層。 _ 請繼續參考第3圖,第3圖為第2圖中程式碼212之示意圖。 程式碼212包含有-應用程式層3〇〇、一第三層介面3〇2、及一第 二層介面306,並與一第一層介面318連接。當發射訊號時,第二 層介面3〇6根據第三層介面3〇2輸出的資料,形成複數個舰資 料單兀(Service Data Unit) 308存於一緩衝器312中。然後,根 據存於緩衝器312中的鎌資料單元遍,第二層介面撕產生複 數個協定資料單元(protocolDataUnit) 314,並將所產生的協定 資料單元314透過第一層介面318輸出至目地端。相反的,當接 收無線訊號時,透過第-層介面318接收訊號,並將所接收之訊 1308827 -號以協定資料單元314輸出至第二層介面·。第二層介面3〇6 則將協疋> 料單元314還原為伺服資料單元遞並存於緩衝器312 中最後’第一層介面306將存於緩衝器312的祠服資料單元3〇8 傳送至第三層介面302。 為了提高資料正確性,當操作於確認模式時,程式碼212會 適時地啟動-傳輸狀態查触程’由鱗通靖輸裝置「查詢」 籲(Poll)接收端,以要求該接收端傳輸一狀態回報單元或一炎帶 式(Piggybacked)狀態回報單元,從而獲知資料之傳輸狀況。無 線通訊傳輸裂置則根據接收端輸出的㈣喃單元,執行後 續運作。當無線通訊傳輸裝置200查詢接收端時,無線通訊傳輸 裝置200選擇-協定資料單元(pr〇t〇c〇1DataUnit),將該協定資 料單元的查詢位元(PollingBit)設定為啟動(=1),以提示接收 端輸出狀態回報單元。 • 在本發明中,為了避免習知技術中傳輸端無法成功查詢接收 端的情形,直覺地可於程式碼212中設定當刪除伺服資料單元的 流程被啟動時,不將緩衝器312内的協定資料單元刪除,而只有 在下一預期確認之協定資料單元的序號被更新時,才可將緩衝器 312内的協定資料單元刪除。如此一來,當重傳協定資料單元許多 次或等待確認訊號很久,以致啟動刪除伺服資料單元的流程時, 存於緩衝器312的協定資料單元不會被立即刪除,因此無線通訊 •傳輸裝置20〇可以成功選擇協定資料單元來查詢而不會發生錯 1308827 ,誤。上述的方法雖然可以解決習知技術中傳輸端無法選擇用來查 詢的龄單元之_,蚁雜财_是紐職不必要 的查詢(亦即當所有存於緩衝器312的協定資料單元在被確認之 前就已啟動刪除伺服資料單元的流程時)。目此,本發明另提供一 種查詢資料傳輸狀況的方法^ 請參考第1圖’第1圖為本發明較佳實施例_ 1〇之流程 φ圖。流程10肋於第三代行動通訊祕巾查詢倾傳輸狀況,其 可被編譯至程式碼212中,流程10包含以下步驟: 步驟100 :開始。 步驟102 ’斷傳輸端是否無協定資料單元被安排傳輸或重 傳。若是’則進行下一步驟,若否,則進行步驟12〇。 步驟104 :判斷傳輸端查詢接收端之流程是否被觸發,若是, 則進行下一步驟,若否,則進行步驟12〇。 鲁 步驟106:判斷傳輸端查詢接收端之流程是否被禁止,若否, 則進行下一步驟,若是,則進行步驟12〇。 步驟108 :纖雜敵緩衝||巾是否有已被傳輸但尚未被確

重傳,而查詢接收端之_被觸發,且查詢接㈣之流程未被禁 止時’本發明係於判斷緩衝时具有已被傳輸、未被刪除、且尚 未被確認的協定資料單元時,才進行查詢動作。如此—來,當所 有存於傳輸端之緩衝器的協定資料單元在被確認之前就被刪除 Φ時’本發明即停止查詢的動作,因此可避免不必要的查詢。 …舉例來說,若傳輸端的傳輸窗大小為4,且傳輸端已傳送序 號ίΓ L、2、3的協定資料單元。若重傳序號為0小2、3的 協=貝料單7G已傳送過許多次或等待確認訊號過久,使得刪除伺 服資料單元的流程被啟動,因此序號為G、卜2、3的齡資料單 2皆由傳輸端的緩衝器中刪除,則傳輸端的緩衝器中無任何協定 鲁身料單兀。此時,若傳輪端無其他協定資料單元被安排傳輸或重 傳而傳輪&查5句接收端之流程被觸發,且傳輸端查詢接收端之 L程未被不止根據流程1〇 ’本發明先判斷傳輸端之緩衝器中是
