Description

於個人導航裝置中之自動增益控制
本發明有關於一種導航裝置。
導航裝置(包括個人導裝置(PND)與汽車中電子裝置)根據此導航裝置之位置,將資訊輸出給使用者。此種導航裝置通常使用全球定位系統(GPS)以判斷位置,且然後使用擴音器及/或顯示器,以輸出地圖資訊、指示等。
為了持續擴充及/或改善由導航裝置所提供之特色,而存在一種需求,將用於導航裝置獲得例如至網際網路之網路接取之機會最大化。本發明在以下所揭示之內容解決此與其他問題。
以下為本發明總結,其目的在於提供本發明一些觀點之基本瞭解。此總結之用意並非在於辨識本發明之關鍵/重要元件,或界定本發明之範圍。此總結之唯一目的為,以簡化形式呈現本發明之一些觀念,作為在稍後提供更詳細說明之序言。
在一實例中,一藍芽能力導航裝置與一行動電話配對,以及然後使用行動電話各以不同傳輸功率增益倍數,將複數個調整傳輸發出至遠距伺服器。此等調整傳輸使用頻率音調編碼,此等頻率音調將語音(speech)合成,用於經由行動電話與其無線電信網路之一語音頻道而傳輸。此導航裝置然後根據對所調整傳輸之所接收響應,調整傳輸功率設定,以及使用特定行動電話,以此所調整傳輸功率設定,用於隨後至遠距伺服器之傳輸。本發明額外之觀點與優點將由以下較佳實施例之詳細說明並參考所附圖式而為明顯。
圖1說明一系統,其使用藍芽能力行動電話對於一具有導航裝置之遠距伺服器進行接取。
系統100包括一導航裝置5,其被組態經由此等行動電話1A-B之可供使用之一,將資料上傳至遠距網際網路協定(IP)伺服器15。此軟體8與軟體18交換調整通訊,而以至少每電話基礎(per-phone basis)以調整傳輸功率增益,且然後根據此等行動電話1A-B之那一個目前可供使用,而使用此經調整傳輸功率增益倍數。此以至少每電話基礎之調整,允許導航裝置5在廣泛種類行動電話與無線電信網路上與遠距伺服器15通訊,其再將用於導航裝置5之通訊機會最大化。
為了瞭解此種調整如何將從導航裝置5至伺服器15之通訊機會最大化,考慮此從導航裝置5至伺服器15如何傳輸通訊,是取決於行動電話1A或1B之那一個被使用而不同地處理。首先,取決於行動電話1A或1B之那一個被使用,此通訊將由不同之通訊電路例如語音編碼器20與21處理。各此等語音編碼器20與21可以不同地影響信號之功率增益,例如藉由改變功率增益不同倍數。此外,與各行動電話1A或1B有關之不同無線電信網路26與27亦可具有不同之語音編碼器22與23,其亦可以不同地影響信號。由於此等差異,在缺乏至少每電話基礎調整之情況下,此接收器所接收信號取決於處理傳輸之語音編碼器之組合,而會太弱或太強。雖然對於伺服器15及/或頻帶內信號傳輸(IBS)數據機19可以偵測到,由於將太弱或太強信號恢復所產生之誤差,並請求重新傳輸,然而,此種傳輸耗費時間,且仍然會導致信號太弱或太強。
相反的,系統100以至少每電話基礎以調整傳輸功率增益,且允許來自導航裝置5之傳輸29A由IBS 19接收且恢復,不會有誤差或最小誤差,而不論導航裝置5使用傳輸路徑30A或30B。換句話說,儘管在路徑30A與30B間之差異,傳輸29B與29C可以具有實質上類似功率增益。
此以至少每電話基礎之調整意味著,傳輸功率增益可以根據特定可供使用電話而設定,而並不僅對可供使用電話之特定製造或模式而調整。兩個相同製造或模式之行動電話亦可以不同地影響信號強度,因為在此等行動電話中之組件可以具有不同之操作特徵。例如,電子組件典型地在值之範圍中評估其性能表現。因此,此等電子組件之一些在此範圍之高端操作,而其他組件是在此範圍之低端操作,此可導致在處理期間相同模式之兩個語音編碼器將一信號不同地放大。例如,相同模式之兩個電阻器可以顯示不同電阻,且此等差異再會影響功率增益。為此原因,軟體8與軟體18是以至少每電話基礎而非每模式基礎調整傳輸功率。
雖然軟體8與軟體18是以至少每電話基礎調整傳輸功率,應注意,在某些例中此種調整可以甚至更精細。此將參考圖2稍後更詳細討論。
仍然參考圖1,應瞭解系統100而因此將用於導航裝置5之上傳機會最大化。以另一種方式而言,導航裝置5並不受限於使用任何特別指定電話與IP伺服器15通訊,而是當在幾乎任何藍芽能力行動電話之範圍中時,可以接取伺服器15。
除了在先前段落中所說明之點,此導航裝置5較佳使用行動電話,用於上傳至IP伺服器15,而不論此可供使用行動電話是否支持:在其無線電信網路上之封包資料連接。例如,此所說明之行動電話1A-B並不支持在其無線電信網路26與27上之封包資料連接,但可以由導航裝置5使用於IP網路接取,如同在下一段落中將說明者。
為了此與其他原因,此從導航裝置5至伺服器15之傳輸、包括調整傳輸此將在稍後更詳細討論,是由IBS數據機9調變,用於跨無線電信網路之語音頻道傳輸。此IBS數據機9將所接收之數位資料調變成音訊頻率音調。選擇此等頻率音調將語音合成,以致於該頻率音調以最小衰減或損壞通過:行動電話1A-B之可供使用之一之語音編碼器20/21、以及可供使用無線電信網路26/27中之任何語音編碼器22/23(在網路26/27與伺服器15間之其他網路亦可操作語音編碼器)。在被編碼與調變成音訊音調之前,較佳將此數位資料格式化成一或更多個封包。一封包格式器例如可以備製:在酬載前之標頭與同步樣式。亦可以將錯誤校正位元、加總檢查、以及其他增強添加至此封包。此導航裝置5然後可以在用於語音資料之藍芽連接上發射此IBS調變通訊29A,而在無線電信網路之語音頻道上傳送、經由任何中間網路例如IP網路28、而由IBS數據機19接收與解調變(恢復成位元流),以及然後最後由伺服器15處理。
應瞭解,對於伺服器15之可靠接取,或對於任何遠距網路之可靠接取,使得對於該導航裝置能夠實施廣泛種類之應用。此在導航系統之一部份之導航裝置5上之應用,可以即時地獲得位置為主之資訊。例如,導航裝置5可以獲得:經由GPS判斷靠近目前位置之交通事故有關之即時資訊。此導航裝置5亦可以下載更新至內部導航資料庫,例如以關於新路徑之資訊更新所儲存之地圖。
此外,可以使用在此所說明調整傳輸,將遠距儲存資料提供給:導航裝置5上任何其他型式之應用。此允許將導航裝置5之特徵集合擴充至與導航並無須有關之其他應用。例如,可以使用在導航裝置5上之應用以獲得:股票價格、或經由網際網路而可供使用之其他資訊。應瞭解,對於在導航裝置5上操作之任何型式應用,可以獲得對任何型式網路之接取。
應瞭解,在此所說明之原理可以應用至任何藍芽能力行動裝置,而不論此種裝置是否具有任何導航能力。而且,可以應用以上說明之原理,而不論此裝置與行動電話間之通訊是否使用藍芽或一些其他無線協定。
應瞭解,此功率增益是根據系統輸出信號功率對系統輸入信號功率之比。當使用傳輸功率增益此專有詞時,此相關系統為導航裝置5(或另一被組態將資料上傳至伺服器之裝置)。當使用接收功率增益此專有詞時,此相關系統為伺服器15。
可以使用調整增益之任何已知方法,在導航裝置5上調整此傳輸功率增益。此可以包括:在導航裝置5上電路之輸入級或輸出級中之放大器、可變電阻器、或其他電路組件。
圖2為在圖1中所顯示導航裝置、以及此導航裝置與遠距伺服器間之交互動作,用於調整傳輸功率增益。
導航裝置5包括:由軟體8所更新之表38。此表38稍後被使用根據此可供使用行動電話上之至少一部份,而設定用於傳輸資料之功率增益。
在此例中,導航裝置5與行動電話31之對41建立:在導航裝置5與行動電話31間之藍芽連接。此藍芽連接可以根據在美國專利申請案號12/752,911「USING A BLUETOOTH CAPABLE MOBILE PHONE TO ACCESS A REMOTE NETWORK」中所說明之原理而建立,其在此整個併入作為參考而用於所有目的。而且,此配對可以由來自在導航裝置5上操作應用之請求、或來自導航裝置5使用者介面之請求而觸發。
在此配對期間,此軟體8得知用於行動電話31之藍芽客戶ID。此藍芽客戶ID為整體獨特辨識符,其被使用以獨特地辨識在表38中之行動電話31。
此行動電話31接收來自IP伺服器15之會議啟始請求。導航裝置5處理此請求43,以及然後軟體8使用一機構以延遲會議啟始。例如,軟體8可以藉由以下方式而造成會議啟始被延遲:使用在確認中之位元設定44、或用於延遲會議啟始之任何其他機構。將軟體18組態以觀察位元設定44,以及因此會議延遲啟始。
此軟體8然後產生測試資料45,其藉由使用IBS數據機9、將所接收數位資料調變成音訊頻率音調而傳輸。選擇此頻率音調以合成語音,以致於此等頻率音調經由任何中介語音編碼器,而以最小衰減或損壞通過。在被編碼與調變成音訊音調之前,可以將此數位資料格式化成一或更多個封包。一封包格式器例如可以備製例如:在酬載前之標頭與同步樣式。亦可以將錯誤校正位元、加總檢查、以及其他增強添加至此封包。
此軟體8然後將經調變測試資料45傳送複數次,而各傳輸51是在不同傳輸功率增益倍數而傳輸。例如,此測試資料45可以傳送三次,而各傳輸是在不同傳輸功率增益倍數實施。
在伺服器15上,此軟體18接收傳輸且判斷此接收功率增益。此軟體18傳送回響應52以顯示所判斷之接收功率增益。
在導航裝置5上,此軟體8將用於測試資料各傳輸之接收功率增益、與用於該傳輸之傳輸功率增益相關。此相關可以根據在響應52中所包含之資訊而進行。
此軟體8然後分析所接收功率增益倍數。此分析可以包括:產生一圖形,其包括在一軸上之接收功率增益,以及在另一軸上之傳輸功率增益。假如使用此圖形,則此軟體8可以連接在圖上之點以產生一線,然後使用在所產生圖上之線,以內插傳輸功率增益,而其將在伺服器15產生所想要接收之傳輸功率增益。應為明顯,此接收功率增益之分析可以與此等圖形完全無關地操作,但在任何情形中,此傳輸功率增益是根據所接收之傳輸功率增益之分析而內插。此所內插之傳輸功率增益與在傳輸51中所使用之傳輸功率增益典型地為不同值,但可以從在傳輸51中所使用此等傳輸功率增益倍數之一而簡單地選擇。
此軟體8將導航裝置5組態,以致於此傳輸將為在此分析期間所辨識之功率增益,此可以包括:設定在導航裝置5上之藍芽接收發射器,或控制在導航裝置5上之任何其他軟體或硬體組件。因此,當發生延遲會議啟始61時,此傳輸66是在所設定傳輸功率增益。
如同先前所討論,使用IBS數據機9以調變傳輸66之封包資料67。此IBS數據機9從所接收通訊恢復資料,而此所接收通訊是在所調整接收功率增益。
此軟體8亦將所內插傳輸功率增益儲存於表38中,此表與用於行動電話31之獨特藍芽客戶辨識符相關。此表38在行動電話欄與傳輸功率增益欄中顯示項目,以說明此種相關。然後,當根據使用那一個行動電話以傳輸資料時,使用此來自表38之傳輸功率增益倍數。
此所說明之表38亦包括選擇性欄位,此包含網路辨識符,其在調整期間使用以設定此無線電信網路。可以使用此欄以提供對於調整之額外精細度。如同先前所討論,不同的無線電信網路使用不同之語音編碼器,其在至少一些情形中對於接收功率增益具有相當大影響。因此,在一些例中,此調整為以每個電話為基礎且以每個網路為基礎。此在表38中說明,而此藍芽客戶ID C與兩個不同之傳輸功率增益倍數2.5 dB與3.1 dB有關。
應瞭解,可以使用以上所說明原理,而對於調整增加更多精細度,例如在表中其他欄。例如,取決於目前所使用語音編碼器之模式,可以將相同之電話/網路語音編碼器組合而與複數個經調整功率增益倍數相關。語音編碼器可以在不同模式、例如全速率與半速率模式中操作,以及取決於所使用之模式而可以不同地影響到接收功率增益。因此,在一例中,導航裝置5判斷此語音編碼器之目前模式,以及根據此目前模式,在用於此特定電話/網路組合之傳輸功率增益間選擇。其他可能欄包括:一天中之時間、在無線電信網路與伺服器15間之其他中介網路(其他網路例如為:包括語音編碼器之IP網路)等之辨識。
然後,軟體8可以將可供使用行動電話之藍芽客戶ID(以及可能其他變數例如網路ID)與表38比較,以及辨識傳輸功率增益倍數。軟體8然後使用所辨識傳輸功率增益倍數,以設定在行動電話上之藍芽接收發射器。
一旦設定此傳輸功率增益,則此在伺服器15上之軟體8可以持續監視從導航裝置所接收之傳輸。儘管導航裝置5以相同之行動電話使用相同傳輸設定,此接收功率增益可能會隨時間“漂移”或改變。此可以由於許多原因而發生,例如:此導航裝置5與可供使用行動電話在網路間漫遊、僅改變其距發射塔之距離、進入或離開功率節省模式等。在任何情形中,此軟體18可以觸發在導航裝置5上之軟體8,而在任何時間啟始新的調整過程。
軟體18可以判斷:何時需要新的調整過程而使用任何過程。在一例中,軟體18持續監視此來自導航裝置傳輸之接收功率增益,且假如此所接收功率增益落在一臨界範圍之外,則觸發新的調整過程之啟始。在另一例中,此軟體18監視此隨著時間之傳輸誤差率,以及假如此傳輸誤差率超過一臨界值,則觸發新的調整過程之啟始。由於傳輸誤差可能與功率增益以外之其他因素有關,此軟體18可以進行一些最少之故障排除,以排除傳輸誤差,其並不可能由於此傳輸誤差率而由功率增益所造成。
雖然在以上所說明之例中,是由伺服器15發出會議啟始請求43。在其他例中,此導航裝置5可以在發射期間之前、後、或期間實施調整,而發出會議啟始請求。在此種例中,軟體8可能無須造成會議啟始之延遲。
圖3說明在圖1與2中所顯示導航裝置如何調整傳輸功率增益。
在方塊301中,此導航裝置與一行動電話建立一藍芽連接,用於與遠距伺服器通訊。此藍芽連接可以如同在美國專利申請案號12/752,911「USING A BLUETOOTH CAPABLE MOBILE PHONE TO ACCESS A REMOTE NETWORK」中所說明地建立。
在方塊302中,此導航裝置將用於行動電話之獨特辨識符(以及可能為其他屬性,例如網路辨識符)與一表比較,此表將行動電話與經調整傳輸功率增益倍數相關。假如在菱形303中判斷,在表中有用於行動電話之項目,則在方塊304A中,此導航裝置根據用於行動電話之經調整傳輸功率增益,而設定一藍芽接收發射器。此導航裝置啟始與遠距伺服器之會議,而以在方塊305中以所設定之傳輸功率增益將資料上傳。
假如在菱形303中判斷,在表中並無用於行動電話之項目,則在方塊304A中,此導航裝置延遲啟始與遠距伺服器之會議。在方塊306中,此導航裝置將所接收之數位位元序列調變成音訊信號,其具有用於不同位元值之不同頻率音調,而選擇此頻率音調以通過此無線語音頻道。在方塊307中,此導航裝置使用不同的傳輸功率增益倍數,以傳輸音訊信號。
在方塊308中,此導航裝置接收對此傳輸之回傳之響應,以顯示在遠距伺服器之接收功率增益倍數。在方塊309中,此導航裝置藉由分析此接收功率增益倍數,以決定用於該行動電話之經調整傳輸功率增益。在方塊310中,此導航裝置在表中產生用於該行動電話之項目,而將此經調整傳輸功率增益與行動裝置相關。然後,此過程回至方塊304A。
圖4說明在圖1與2中所顯示伺服器如何調整傳輸功率增益。
在方塊401中,此伺服器接收音訊信號之複數個傳送。在方塊402中,此伺服器判斷用於各此等傳輸之接收功率增益,且發出通訊以辨識對於導航裝置之接收功率增益。
然後,在方塊403中,此伺服器接收具有經調整接收功率增益之傳輸。假如此隨後所接收傳輸所具有接收功率增益是在臨界範圍之外,則在方塊404中,此伺服器可以信號通知導航裝置進行一新的調整過程。然後,此過程回至方塊401。
對於熟習此技術人士為明顯,可以對以上說明之實施例之細節作許多變化,而不會偏離本發明之基本原理。因此,本發明之範圍應僅由以下申請專利範圍所決定。
以上所討論大部份設備包括:硬體與有關軟體。例如,此典型的導航裝置可以包括:一或多個處理器,以及在此等處理器上可執行軟體,以執行所說明之操作。在此所使用專用語「軟體」為通常所瞭解之意義,是指程式或常式(次常式、物件、插入等)、以及可以由機器或處理器所使用之資料。如同所熟知,電腦程式通常包括:儲存於機器可讀取或電腦可讀取儲存媒體中之指令。本發明之一些實施例可以包括:儲存於機器可讀取或電腦可讀取儲存媒體例如數位記憶體中之可執行程式或指令。此並不暗示在任何特定實施例中需要傳統意義中之“電腦”。例如,各種處理器、嵌入式或其他而可以使用於設備例如在此所說明之組件中。
此用於儲存軟體之記憶體再度為所熟知。在一些實施例中,與一給定處理器有關之記憶體可以儲存在與處理器相同之實體裝置中(“車上”記憶體)。例如,隨機存取記憶體(RAM)或快閃記憶體(FLASH)是設置在積體電路微處理器等中。在其他例子中,此記憶體包括一獨立裝置,例如:一外部硬碟機、儲存陣列、或可攜式FLASH鑰匙圈(key fob)。在此等情形中,當記憶體與數位處理器例如藉由輸入/輸出埠、網路連接等而操作地耦接在一起或彼此通訊時,記憶體成為與數位處理器“連接”,以致於處理器可以讀取儲存在記憶體上之檔案。此連接記憶體可以藉由設計(ROM)、或藉由允許設定或否而可以“唯讀”。其他例子包括但並不受限於:WORM、EPROM、EEPROM、FLASH等。此等技術經常於固態半導體裝置中實施。其他記憶體可以包括移動部份,例如傳統之旋轉硬碟機。所有此等記憶體為“機器可讀取”或“電腦可讀取”,且可以被使用以儲存可執行指令,用於執行在此所說明之功能。
一“軟體產品”是指記憶體裝置,其中一系列可執行指令以機器可讀取形式儲存,以致於對於軟體產品具有適當存取之合適機器或處理器,可以執行此等指令,以實施由此等指令所執行之過程。軟體產品經常使用於分佈軟體。任何形式之機器可讀取記憶體,其包括且並未受限於以上所總結者,可以被使用以製造軟體產品。這即是亦為所熟知,可以經由電子傳輸(“下載”)而分佈軟體。在此情形中,典型地在此傳輸之發射端會有相對應之軟體產品,或在接收端會有相對應之軟體產品,或在發射端與接收端均有相對應之軟體產品。
本發明之原理已經在其較佳實施例中說明與描述。此應為明顯,本發明可以在配置與細節中修正,而不會偏離此原理。本發明對於在以下申請專利範圍精神與範疇中之所有修正與變化作主張。
