網路協助的LTE通道獲取
本發明有關用於使用者裝備之網路協助的LTE通道獲取，且更特別地，有關用於無線電局部區域網路(WLAN)連接的使用者裝備之網路協助的LTE通道獲取。
行動資料係計劃要自2012年至2017年以百分之66的估計之CAGR迅速成長。透過新的基地台之部署或高等技術升級以縮放網路容量並非跟得上行動資料需求之可實行的選擇。因為Wi-Fi已在智慧型手機、平板電腦、及筆記型電腦上變成標準的特性，所以卸載行動資料至miWi-Fi正幫助業者解決他們現正面對的資料成長。依據2013年3月中之GSMA無線電情報報告，Wi-Fi占行動之無線電資料話務的幾乎三分之二，且在年底，業者具有三百八十三萬個Wi-Fi存取點於適當位置處。該等數目正開始反映出在高度先進之市場中所見到的Wi-Fi趨勢，例如，在其中Wi-Fi卸載係常見的美國、南韓、及日本。日本的KDDI係在本月中以其行動資料話務的一半被卸載至其 Wi-Fi網路為目標，而自2012年的年底之43%提高。另一方面，在全美國操作32000個其擁有之熱點的AT&T之最近所公佈的統計顯示出，在2012年中，其Wi-Fi網路之連接的年增率超過一倍。當智慧型手機或其他的行動裝置係經由Wi-Fi而被漸增地連接至網際網路時，其變成較不企望保持智慧型手機的LTE連接主動，因為此將典型地快速消耗電池及浪費LTE無線電資源。然而，若將LTE無線電關閉時，則此行動裝置會典型地花費長的時間以被重新連接至LTE網路。

第4圖描繪依據本發明一實施例之實例WLAN AP的方塊圖400。在此實例中，WLAN AP 220係大致地組構以接收來自IRP管理器之最佳的實體層訊胞識別及/或LTE頻帶資訊(X)，且使該最佳的實體層訊胞識別及/或LTE頻帶資訊格式化成為無線電訊框(例如，802.11可相容的訊框格式)。WLAN AP 220亦係大致地組構以週期性地廣播包含最佳的實體層訊胞識別及/或LTE頻帶資訊的無線電訊框至該WLAN AP之涵蓋區域內的至少一UE。此實例之WLAN AP 220包含802.11訊框邏輯402，其係組構以使實體層訊胞識別及/或LTE頻帶資訊格式化成為無線電訊框格式之可相容者，例如，802.11可相容的訊框格式。 WLAN AP 220亦包含LTE通道獲取元件廣播邏輯404，其係組構以週期性地廣播包含實體層訊胞識別及/或LTE頻帶資訊的無線電訊框至該WLAN AP 220之涵蓋區域內的至少一UE。此處，包含實體層訊胞識別的無線電訊框係稱為“LTE通道獲取元件”。如就此處所使用之“週期性地”用語而言，其係大致地界定為頻率，其中LTE通道獲取元件係藉由邏輯404而在該頻率中被廣播到至少一UE。其中邏輯404廣播LTE通道獲取元件之頻率可根據例如，使用者界定之值、網路啟發式(例如，UE花費在 WLAN AP之涵蓋區域內的平均時間、特定UE的歷史時間週期、等等)、網路拓樸統計(例如，目前之訊胞涵蓋區域、等等)、在WLAN AP涵蓋及/或訊胞涵蓋中的改變、話務負載、與UE/eNB相關聯之服務品質(QoS)等級、使用者優先序等級、等等而定。

儲存媒體可包含任何類型之有形的儲存媒體，例如，包含磁盤、光碟、小型碟片僅讀記憶體(CD-ROM)、小型碟片可再寫入式(CD-RW)、數位多功能碟片(DVD)、及磁光碟之任何類型的碟片，諸如僅讀記憶體(ROM)、諸如動態及靜態RAM之隨機存取記憶體(RAM)、可拭除可編程之僅讀記憶體(EPROM)、可電性拭除可編程之僅讀記憶體(EEPROM)、快閃記憶體、磁性或光學卡之半導體，或適用以儲存電子指令之任何類型的媒體。
如此處之任一實施例中所使用的“電路”可單一地或任何組合地包含例如，硬線電路、可編程電路、狀態機器電路、及/或儲存由可編程電路所執行之指令的韌體。應用可被實施成為碼或指令，其可在諸如主處理器的可編程電路或其他的可編程電路上被執行。如此處之任一實施例中所使用的“模組”可被實施成為電路、軟體、指令組、碼(例如，源碼、可執行碼、等等)、等等。該電路可被實施成為諸如積體電路晶片之積體電路。
因而，本發明提供用以當UE移動超出WLAN涵蓋時，自無線電局部區域網路(WLAN)連接有效率地躍遷至LTE/LTE-A網路訊胞連接之裝置、方法、系統、及電腦 可讀取儲存媒體。以下實例屬於進一步的實施例。
