201115957 六、發明說明: 【發明所屬之技術領域】 本發明概括而言是有關無線通訊系統,特別是,本發明是 有關在該糸統中多媒體廣播及多播服務的頻道切換及排程。 【先前技術】 在無線通訊系統中使用多媒體廣播/多播服務(MBMS)的需 求正在上升,對於特定的MBMS而言,網路中一個授予的胞元 可能具有無、一個、或多個的使用者、無線傳送/接收單元 (WTRUs),而使用該MBMS。當使用者在胞元間遷移時,一原 本可能具有一個或沒有使用該服務的使用者的胞元在稍後可能 會有多個使用該服務的使用者,相反地,一個在一點具有多個 使用該服務的使用者在另一時間可能只有一個或沒有使用者。 使用者的遷移會產生無線資源無效率的使用。如果只有一 個或很少的使用者在該胞元使用該MBMS,對使用者來說使用 專用頻道來支援該服矛务是值得嚮往的,專用頻道可利用功率控 制及波束導向以減少用來支援MBMS之無線資源的數量。 然而,如果太多使用者使用在該胞元中的MjgMS,則多個 專用頻道總計可能會用到相當大量的無線資源,在這種情形 下,一個較理想的無線資源使用可能會是透過一個共有/共享頻 道來發送MBMS資料給一群使用該mbMS的使用者。雖然在 該if开>下使用波束導向和功率控制會受限制,但總頻道數量的 降低可減少無線資源的使用。當在胞元中MgMS使用者的數量 改變,原本不是共有/共享頻道就是專用頻道的選擇在後來就不 是那麼地理想了。 201115957 另一個由使用者遷移所導致的潛在問題乃是MBMS的排 程。當一個MBMS使用者在胞元間移動時,該使用者需要藉由 接收自兩胞元的資訊以重新建立MBMS服務,如果兩胞元同步 化他們的MBMS傳送’該MBMS使用者就能在胞元間無間隙 的移動’然而’類似的情景通常不會實現且會令人失望。在基 於胞元裝載和有效資源的某種程度時間間隙下,其中一胞元在 某時可能會比在另一時間具有較多的有效資源以支援MBMS 傳送,因此,在該時間讓該胞元傳送較大量的MBMS資料就令 人滿意,對於另一個在同一時間間隙的胞元而言,支援相同 MBMS頻寬的資源並無法利用。因此,在胞元間替MBMS傳 送做不同的排程以更有效利用該資源就頗令人渴望。當MBMS 使用者在胞元間移動時,使用者移動進入的新胞元其傳送不是 在另一胞元的傳送之前就是之後,因此,MBMS使用者就可能 漏失MBMS資料或接收無用多餘的MgMs資料。 因此,讓MBMS具有較佳資源利用就成為眾人渴求的事。 【發明内容】 本案係包含一種無線存取網路與一種用以發送使用頻道切 換的多媒體廣播/多播服務(MBMS)的方法’該頻道切換係介於 專用與共有/共旱頻道之間。本案亦包含使用於當一無線傳送/ 接收裝置接收來自多個傳送來源的一 服務時的 接收排私。此來源係已不同的次序來傳送該Mbms服務資料。 在一實施例+其使用頻帶内區段資訊,而在另一實施例中則使 用頻帶外同步資訊。 【實施方式】 201115957 雖然較佳實施例說明是結合第三代伙伴計晝(3Gpp)寬頻分 碼多工存取(W-CDMA)系統,但實施例也適用於任何使用 MBMS的無線系統,之後的無線傳送/接收單元(WTRu)包含但 不限制於-個者錢、行動基地台、岐或行動制者單元、 呼叫器或任何形式可在無線環境操作下的裝置。 第一圖是一用以讓MBMS頻道切換之流程圖。在一特定胞 兀,使用該服務之WTRUs數量是由步驟2〇所決定或估計,典 型地,這資訊是已知的。使用在該胞元及/或其他胞元資訊中 WTRUs的數目,例如航狀態、可利用的胞元資源等等之類的 資訊,是否使用專賴道或共有/共享頻道或兩者皆㈣選擇, 即步驟22。在頻道選擇決定之後,該廳·資料就會映像至 對應的頻道,即轉24。-種可能接近的方法以蚊何種類型 的頻道被使用即是-朗檻職’如果WTRUs在就的數量 低於某值,則使料用頻道’該專用頻道允許功率控制並且會 利用傳送差異技術’這些技術糊當高資料速率的廳泌的傳 送產生時,會有效率地使用可利用的資源。 如果WTRUs數量超出門插值,即使用共通/共享頻道,例 如一共享頻道、-高速共享頻道或者是—輔助共通控制實體頻 道(S-CCPGH享頻駐g速共享頻道紐絲同時傳送 MBMS資料給多數個WTRUs,紙顚則能被用來廣播 MBMS紐給錄個制者’典魏,該共享/共賴道就 低的無線資源效率。 在另-貫施例巾H個兩門檻的方案。如果在胞元中 使用MBMS的WTRUs的數量低於第一個門檻值,即使用專用 頻道,如果數量在第-和第二門餘之間,即使用共享或高速 6 201115957 共享頻道,如果數量超過第二門權值,即使用共通頻道來廣播 MBMS。 在某些狀況下,可能會較渴望使用共享和專用兩種頻道以 支持MBMS。為了說明,很多使用的WTRUs可能會定位在一 起’例如在一列基地台,而少數或單一 *71111可能就在一列基 地台外,在此情況下,胞元資源最有效率的使用以支援MBMS 可能是分配一共享頻道給一列基地台上的WTRUs,而分配一專 用頻道給其他的WTRU ’當在胞元中使用者的數量改變,胞元 狀態改變或頻道選擇會週期性的重複使用新資訊,即步驟26。 第二圖是一用以執行頻道切換之較佳無線存取網路(RAN) 之圖示,該RAN係由管理使用者服務的服務網路控制器(lrnc) 30以及管理胞元實體資源之控制無線網路控制器34 所管理,在S-RNCs 30及C-RNC 34之間提供用於ran進行適 當操作所需協調的信號發出程序會被使用。 一頻道切換實體(MBMS頻道切換裝置36)決定該用哪個頻 道,例如專用、共旱或共通’提供MBMS傳送且其亦協調WTRUs 叫至4〇n (40)之MBMS接收,MBMS資料則透過B節點38被 送往 WTRUs 40。
一頻道切換之較佳實施方式如下所述,一使用MBMS之第 一 WTRU 40能自主地進入和離開胞元,其係有關mbMS服務 之啟動及分佈狀態,當MBMS首先為該第一 WTRU40或少數 在特定胞元的使用者建立時,專用頻道會隨著一辨識MBMS服 務之獨特無線鏈路(RL)指示器而建立,一欲使用其他mbMS之 第二WTRU 40會具有一個不同的專用頻道分派給該使用者,當 該壯為每一使用者建立後,一獨特MBMS指示器會從S-RNC 201115957 30發送信號至C-RNC34 ’該MBMS指示器對每一提供給該使 用者之服務而言都是獨特的,該C-RNC 34維護一所有對特定 MBMS服務而言正在使用中的使用者之資料庫,且該群組被認 知為MBMS使用者群。 每一啟動之MBMS服務之資料會由核心網路28透過 MBMS資料流分配給C-RNC 34,一獨特與每一 MBMS資料流 相連的辨識子允許該C-RNC 34以連接該資料與適當的使用者
或使用者群’以便該資料能合適地排定路由。根據特定MBMS 服務之啟動使用者數量及胞元狀態,該C—RNC 34將決定是否 服務該在專用或共享/共通頻道上傳送。 既然個別使用者自動地進入或離開該胞元,專用和共通頻 道間的切換即動態且可能在不間斷進行的傳送時發生。動態切 換能適用於下行通路共享頻道(DSCH),資料能在DSCH上送出 以被與專用DSCH (C-DSCH)相關之單一使用者或同時地被多 數個與共通DSCH (C-DSCH)相關之使用者接收。對一特定的 MBMS來說,當僅有一個使用者或少數使用者在胞元内離開, 對使用者或是多個使用者來說DSCH將成為D_DSCH,而當與 特定的MBMS相關的使用者數量增加,為該MgMs使用者群 將建立C-DSCH 〇 當該第一 WTRU 40成為在胞元間為啟動,一 D_DSCH將 為該第一使用者建立,MBMS傳送可能就不需要連續處於啟動 狀態’在DSCH上MBMS的傳送會被指示給在相連專用頻道上 之該第- WTRU 40,這項指示可在傳送時間間隙(TTI)基礎上開 啟或關閉。 C-DSH也許實質上相同於D_DSCH,然而不同之處在於, 8 201115957 ㈣物㈣人使用者之 所右步傳送’其允許顧^使用者群組中的 # 能接收到共同的DSCH_。 ,發出W ’以指示專用於特较用者或是共通於使用者 帛麵_s _,_魏__之適當操 运夕元化或任何其他獨特的實體傳送特性。專用DSCH 。共通DSCk間的mbms轉換係較wtr來得清楚。 在另實施例中’頻道切換係應用於高速dsch(hs_dsch) 上。使用卿SCH來取代Dsch之差異在於其並非於c捕⑶ 之相關專用頻道上使用同步分配,其同步分配係使用B節點如 之HS-DSCH控制頻道上。 在又-實施例中’切換可以在不使用相關專用頻道下,於 專用實體紐與共通實_道之聰生。專·道與共通頻道 之間的頻道切換會明確地發出信號給每個使用者。MN第三層 協定允許發送無線電幅至專用與共通頻道之間的轉換之程序, t號毛送係以發送轉換之無線電幅或以發送傳送排程資訊的方 式來執行。 ,第三圖與第四_為允許不同胞元财同胞元内MBMS 傳,來排人不同順序之流程圖。為了說明起見,假設一第一胞 元月b夠在一無線電幅内傳送大量mbMS資料至WTRUs,而第 二胞凡不能’結果’在第一胞元内之顧奶傳送可能超前第二 胞元一或多個無線電幅或TTIs。 為了說明胞元内’在一胞元内部,一組使用者係可能位於 火車站中並接受共通DSCH的服務,而在同一個胞元内的其 他使用者係處於火車站外並接受專用頻道或專用DSCH的服 201115957 務,以充分利用波束成形及電力控制。根據DSCH負載及其他 因素,火車站WTRUs40的傳送領先或落後WTRU外的傳送, 皆疋令人滿意的。假如位於WTRUs外的使用者進入火車站, 最有可能令人滿意地轉換WTRU 4〇至共通DSCH,並解除專用 頻道。在這種情況下,外部WTRU 4〇需要趕上共通DSCH的 傳送,或是允許該傳送趕上WTRU4〇已接收到的區段。 為了維持持續的服務分配並更有效率地使用無線電資源, MBMS傳送較佳地係區段化或排程化,以讓使用者在任何情況 下都此接收到MBMS服務傳送的單元。因此,mbms服^務傳 送並不需要於使用者通道上之胞元進行再次初始化,且使用者 也不需要等待與存在之MBMS服務傳送進行同步化。 第二圖係為使用頻帶内區段資訊來控制胞元内或胞元間之 不同MBMS傳送順序。隨著mbMS傳送,區段資訊係隨著 MBMS資料一起被發送,步驟42。該區段資訊典型地包含一區 段辨別器’以使每個接收WTRU皆能辨別其接收的區段。當特 定WTRU於MBMS傳送來源間移動時(在胞元或切換頻道之 間)’步驟44 ’ WTRU能從新的MBMS來源接收區段,並重 組該傳送以回復所有的MBMS資料,步驟46。 第五圖係為WRTU 40接收不同MBMS傳送之簡化方塊 圖° WRTU 40係使用一天線54來接收mbms傳送。MBMS 接收器56從不同傳送來源接收mbMS傳送,其中包含了頻帶 内區段資訊。一區段資訊回復裝置58係用以回復區段資訊。使 用區段資訊及接收的MBMS區段,一 MBMS區段重組裝置60 係重組區段以回復MBMS資料。
第四圖係為使用頻帶外傳送排程資訊來控制不同MBMS 201115957 傳送順序之流程圖。WTRU從一特定來源接收MBMS傳送,步 驟48 ° WTRU也接收頻帶外排程資訊’步驟5〇。當WTRU移 動至不同的來源’ WTRU能從新的來源接收MBMS資料,並使 用該來源之頻帶外排程資料來重組MBMS接收區段,步驟52。 第六圖係為WRTU接收不同MBMS 40傳送之簡化方塊 圖° WTRU 40係使用一天線54來接收MBMS傳送。MBMS 接收器62係從不同傳送來源接收mbMS傳送。一頻帶外同步 資訊回復装置64係從多重傳送來源接收同步資訊。使用同步資 訊及接收MBMS區段,MBMS區段重組裝置66係重組區段以 回復MBMS資料。 第三圖及第四圖的方法皆允許位於胞元内的使用者在專用 與共通頻道之間進行適當的轉換,而不需中斷或延遲MBMS傳 送。此外,即使新胞元與舊胞元之間的傳送順序不同,進入胞 元的WTRU仍能持續接收mbms的服務。一旦mbMS傳送資 料被接收,WRTU將依據頻帶内區段及/或頻帶外傳送排程資訊 來記錄資訊。 由於應用了頻帶内區段或頻帶外排程,遺失或失敗的傳送 能有效率地藉由WTRU於再傳料的使用而被回復。 MBMS再傳送触也能藉纟考慮到WTRUs之職接收而降 低。進-步地說’假如RNC知道所有使用者皆接收到一特定 MBMS區段,該區段之再傳送就能被預防。 11 201115957 【圖式簡單說明】 第1圖為一使MBMS頻道切換之流程圖。 第2圖是一用以執行頻道切換之較佳無線存取網路(RAN) 之圖示。 第3圖為來自使用頻帶内區段資訊的多重來源的MBMS之 協同接收流程圖。 第4圖為來自使用頻帶外區段資訊的多重來源的MBMS之 協同接收流程圖。 第5圖為用以接收使用頻帶内區段資訊的MBMS資訊之一 WRTU 〇 第6圖為用以接收使用頻帶外同步資訊的MBMS資訊之一 WRTU 〇 【主要元件符號說明】 54天線 12
