Abstract

於此大致描述用以對例如使用者設備(UE)的多模無線通訊裝置建立及實施應用為基的選路策略的技術。在一些例子中，特別是該UE的設定檔與平台架構的資訊係被傳達給接取網路發現功能(ANDSF)伺服器。該ANDSF伺服器可以提供系統間選路策略(ISRP)，以處理用於該特定應用及裝置架構的適當網路卸載動作。在一些例子中，ISRP可以特定於自某些軟體應用的流量為基或非無縫為基之的話務卸載。於此所述之技術可以由ANDSF伺服器傳遞並可關聯於在3GPP長期演進/長期演進-先進(LTE/LTE-A)演進封包核心(EPC)網路架構中的卸載策略，被實施於各種多模UE行動計算裝置中。

Description

在多模使用者設備中建立應用為基的選路策略
實施例屬於為在無線網路中之通訊裝置所執行之操作與通訊。一些實施例關係於裝置資訊及建立以為無線網路所促成的資料通訊的選路策略。
例如依據來自3GPP長期演進/長期演進-先進(LTE/LTE-A)標準系列之標準操作的網路的載波為基之無線通訊網路佈署機制，以協助網路策略的發現與管理。在LTE/LTE-A網路中，此一技術涉及使用在LTE/LTE-A系統架構之演進封包核心(EPC)內的接取網路發現功能(ANDSF)規則及策略。例如，ANDSF規則及策略可以特定於多模使用者設備(UE)，以發現非-3GPP接取網路，並協助多模UE以建立至一Wi-Fi無線區域網路(WLAN)(例如，依據IEEE802.11標準操作之網路)或WiMax無線廣域網路(例如，依據IEEE802.16標準操作的網路)所連接。然而，現行策略並未針對特定應用要 求或特定裝置能力。

以下說明與附圖足夠顯示特定實施例，以使得熟習於本技藝者實施這些實施例。其他實施例可以加入有關結構、邏輯、電氣、製程及其他方面的變化。一些實施例的部份與特性可以被包含或替代其他實施例中。於申請專利範圍中所述之實施例包含所有這些實施例可得之等效。
於此所述之各種技術與架構完成了ANDSF為基之策略的建立與操作，其可以被佈署以針對特定的裝置/網路實施法及卸載使用例子。在ANDSF策略中所因素的資訊可以包含特定應用及裝置的架構，包含裝置類型、硬體版本、作業系統類型及版本、軟體應用類型及版本、及如同UE架構的細節。這些UE架構細節可以被用以建立及佈署特定系統間選路策略(ISRP)，以控制安裝在該UE內的應用間的話務選路及行動力。
在LTE/LTE-A系統架構中，ANDSF伺服器可以提供：用以協助交遞決定之系統間行動力策略；用以同時在多數無線電接取介面上配送IP話務的ISRP；及用以指示非-3GPP接取網路的發現資訊，其可以有用於UE的附近，以協助UE以連接至此等網路。幾個不同策略可以特定為用於IP流量行動力卸載技術的ISRP的一部份。
作為話務選路及行動力的例子，能夠透過在多模使用者設備(例如WLAN及細胞式)中的多數無線網路介面通訊的某些應用可以選擇以配送所有話務於一介面(WLAN)，而不是另一個。ANDSF為基之策略係為一 載波網路操作者所控制並想要以網路卸載之規則為基之管理補充此情景。ANDSF機制可以為了各種理由與狀況，例如，在某些區域中的一天中之某些時間管理卸載及網路接取或為了某些流量，代表操作者而輸送策略及策略資訊至UE。
然而，現行ANDSF為基之策略並未提供機制，以適當地針對特定應用的喜好與策略。例如，視訊為基之應用可以選擇使用WLAN連接，而語音應用則可以選擇使用細胞式連接。再者，用以執行卸載的喜好與策略可以取決於UE特定版本或架構，及是否流量為基之或非無縫卸載為特定應用所想要或允許的。
在一例子中，各種資料識別欄位係提出用於ANDSF管理物件(MO)，包含在ANDSF伺服器加入各種應用識別碼，以允許ISRP根據應用身份支援話務識別。對ISRP的現行更新完成了應用身份的增加使用及處理成為IP話務的識別。用以決定適當應用身份的相關資訊不只包含特定應用版本或應用架構，同時，也包含UE版本、UE平台及硬體架構、UE作業系統及類似物的相關欄位。因此，現行描述之資料架構及交換機制完成詳細應用身份與相關資料處理策略及程序的通訊。
圖1提供混合模式之通訊網路架構100的例示架構的顯示圖。在網路架構100中，載波為基之網路(例如，依據來自3GPP標準系列的標準操作之LTE/LTE-A細胞網路)係為載波為基之網路系統102(例 如建立細胞式網路的演進NodeB(eNodeB))所建立，該網路系統102與多模行動裝置(UE)104A、104B相通訊。一本地區域為基之網路系統106(例如，依據來自IEEE802.11標準系列之標準操作的WiFi網路)可以藉由包含WiFi路由器或接取點的本地網路設備加以建立。此載波為基之網路包含分別至行動裝置104A、104B的網路連接108A、108B；及該本地區域為基之網路包含分別至行動裝置104A、104B的網路連接110A、110B。行動裝置104A、104B係被顯示以配合不同形狀因數，包含智慧手機(行動裝置104A)及具有內建或外部無線網路裝置之個人電腦(行動裝置104B)，但也可以了解，也可以使用相同或其他形狀因數。
在各種行動裝置104A、104B間的無線網路通訊連接108A、108B、110A、110B可以使用載波為基之網路系統102或本地區域為基之網路系統106配合各種卸載策略及喜好的佈署加以促成。卸載策略及喜好可以使用一或更多ANDSF策略120，由ANDSF伺服器114透過載波為基之網路系統102(及網路連接108A、108B)加以傳達。
ANDSF伺服器114可以在載波網路的服務提供者網路112內促成。服務提供者網路112可以包含演進封包核心(EPC)的各種元件及3GPP LTE/LTE-A網路的其他元件，包含各種服務118及P-GW(封包資料網路(PDN)閘道)116。卸載至本地區域為基之網路系統106 的資料話務可以透過與P-GW116的連接而傳達回服務提供者網路112。因此，卸載至另一網路架構(無線網路連接110A、110B)的無線網路通訊可以用以接取服務提供者網路112的功能。
圖2提供具有混合模式使用者設備裝置(行動裝置104C)的例示資料操作200的顯示圖，其係有關於圖1的混合模式通訊網路架構100加以執行。如於圖2所示，行動裝置104C被架構以執行具有載波為基之網路系統102的3GPP網路資料206的與外部網路(例如網際網路)122的通訊；及行動裝置104C同時也架構以執行具有本地區域網路系統106的非3GPP網路資料208與外部網路122的通訊。
行動裝置104C被描繪為與具有3GPP網路資料206的第一軟體應用“APP1”傳達資料，及具有在非3GPP網路資料208的第二應用“App2”傳達資料。由各種軟體應用至適當網路的資料之佈署係有關於ISRP策略204加以促成，該ISRP策略204包含由ANDSF伺服器114所提供的一或更多應用策略204A。行動裝置104C係被架構以實行ISRP策略204，以根據應用識別碼(例如App1對App2的指示)指明IP流量行動力應用。
特定應用識別碼及在ISRP策略204中的應用策略204A組係由經由非卸載(例如3GPP LTE/LTE-A)網路接收的ANDSF伺服器114傳達至ANDSF MO內的行動裝置104C。ANDSF MO可以建構為可延伸標示語言 (XML)格式，並可以由行動裝置104C拉出或推入至行動裝置104C。為了決定佈署於ISRP策略204中的適當應用策略，在UE上的資訊與適當應用可以被傳達給ANDSF伺服器114。在一例子中，具有適當UE與應用資訊202A的UE設定檔202也在ANDSF MO中被傳達至ANDSF伺服器114。
在佈署ISRP策略204中使用應用策略204A可以用以針對在UE的應用的網路用途。應用策略204A可以客製化為各種類型之網路用途例子及情景，並包含用以進行由指定應用至選擇網路或網路類型的特定接取或接取組的規則。例如，考量在多媒體播放應用中之視訊編解碼播放。在一些情景中，UE可以播放低品質視訊，其較佳由3GPP接取網路下載。如果想要高清析或更高解析格式的高品質播放，較佳可以令應用使用Wi-Fi或其他次要無線網路。應用策略204A可以用以獨特地識別該應用，並根據載波網路要求及喜好將該應用相關於接取類型規則。
圖3提供ANDSF MO格式結構節點物件302的例示顯示300，其具有一連串的結構次物件，其包含使用者設定檔架構次物件。結構節點物件302的結構次物件可以被界定，用以遵循一特定規格(例如，3GPP LTE/LTE-A規格)並可以包含：界定策略節點樹304A的策略節點次物件304；界定發現資訊節點樹306A的發現資訊節點次物件306；界定使用者設備位置節點樹308A 的UE_Location節點次物件308；界定ISRP節點樹310A的ISRP節點次物件310；界定UE_Profile節點樹312A的UE_Profile節點次物件312(進一步示於圖5中)；及提供販賣者特定資訊的可能定義的Ext節點次物件314。
為指明及佈署應用為基之選路策略而對ANDSF MO的修改可以有關於兩方面加以提供：第一，在UE_Profile節點樹312A中之定義，其包含特定UE硬體架構、作業系統、作業系統版本資訊、及其他UE作業資訊；及第二，如於此所述之在ISRP節點樹310A中之佈署所定義的ApplicationID葉(分別於圖4A及4B中所示之節點樹400、450)。
在UE_Profile節點樹312A中之定義可以經由如圖2所傳達之在UE設定檔202所示的ANDSF MO，用以傳達一般UE及應用操作資訊。指明用於特定應用策略的ApplicationId的節點被用於ANDSF MO中，並在流量為基之及非無縫WLAN卸載機制中佈署於ISRP中。
圖4A及4B分別提供用於ANDSF管理物件、用於流量為基之策略節點樹400及非無縫卸載策略節點樹450的ISRP策略節點結構的例示顯示。ISRP規則組可以包含一或更多流量分佈容器，包含如圖4A所示之IP流量行動力及無縫卸載(IFOM)服務的ForFlowBased節點402、及如圖4B所示之用於非無縫卸載服務的ForNonSeamlessOffload節點452。
ISRP節點分支指明一機制，用以指明為特定 應用產生的話務。流量分佈容器可以具有一或更多流量分佈規則。在用於如圖4A所示之IFOM服務的ForFlowBased節點402中，這些分佈規則包含有關於IFOM卸載機制的用於UE的話務分佈規則。在如圖4B中所示之用於非無縫卸載的ForNonSeamlessOffload節點452中，這些分佈規則包含有關於非無縫卸載機制的用於UE的話務分佈。
在一例子中，ISRP節點係被界定，在ForFlowBased節點402下相關於用於App-ID節點404、平台節點406、PlatformApps節點408、及Platform_specificAppID節點410的定義使用。這些節點的定義可以提供如下：節點：<X>/ISRP/<X>/ForFlowBased/<X>/IPFlow/<X>/App-ID
此內部節點透過應用識別碼作為用於IPFlow識別機制的佔位符。此節點的空出可以用以表示當將封包匹配至該規則的IP流量描述時，應用識別碼並未被檢驗。

圖5提供使用ANDSF MO傳送給ANDSF伺服器114的使用者設定檔節點結構500(例如UE_Profile節點312)的例示顯示。UE_Profile節點結構500可以被安排以包含特徵化可以為ANDSF伺服器114所用以資訊供應的UE的平台架構的資訊。UE_Profile節點結構500係為UE於適當時間更新，例如，在通電之後，或在建立網路連接之前的時間。ANDSF伺服器114係被安排以在UE(例如行動裝置104C)建立與ANDSF伺服器114的連接之後，由UE_Profile節點結構500檢索資訊。然而，包含在這些節點中之資訊的更新並不必然暗示與ANDSF伺服器有任何互動。
UE_Profile節點結構500係被用以界定UE架構並致使UE對網路表示其架構。為了應付多數作業系統支撐要求，ANDSF伺服器114提供包含用以供相關作業系統執行於該UE上的應用ID的策略及硬體平台類型給該UE，以適當地指明該應用。以UE_Profile節點結構500，UE提供所支援的作業系統與硬體架構資訊給該ANDSF，以通知ANDSF取得或下載為支援平台所用的具有應用ID的策略，因此，指明策略所表示之應用。
UE可以支援多數平台架構。與ANDSF伺服器114相通訊的平台架構可以表示可應用的作業系統或執行環境與相關版本資訊。在一例子中，ANDSF伺服器使用來自UE_Profile節點結構500的使用者設定檔資訊，以建立並傳送一特定ISRP(例如客製化至流量基礎策略節點樹400或非無縫卸載策略節點樹450的ISRP)，用以分類應用話務。根據在UE_Profile節點結構500中所指明的資訊，ISRP只被用於為UE平台架構所支援的那些應用。
UE更新在UE_Profile節點結構500中之節點，使得ANDSF伺服器114可以當與UE互動時讀取此資訊。在UE_Profile節點結構500中之資訊可以於例如當伺服器讀取UE的MO時，在開放移動通訊聯盟裝置管理(OMA-DM)交換的同時為ANDSF伺服器114所檢索。
如於圖3所示，MO具有節點(UE_Profile節點312)，其表示UE的架構並包含UE_Profile節點結構500。UE_Profile節點結構500詳細指明UE的硬體平台及為該UE所用或可用的作業系統或執行環境。包含在這些節點中之資訊的更新並不必然暗示與ANDSF伺服器114的任何互動。然而，MO致使ANDSF伺服器114被通知有關該UE的硬體架構、安裝在該UE上的作業系統及該作業系統的版本、及其他相關UE設定檔資訊。根據此資訊，ANDSF伺服器114可以產生並提供對應於UE架構的特定應用識別碼(及因此，客製化特定ISRP策略至特定應用識別碼)。
作為實施的特定例子，以下節點及UE_Profile節點312及UE_Profile節點樹312A的葉物件可以設在ANDSF MO格式結構節點物件302下：節點：<X>/UE_Profile/

平台葉指示為該UE所支援的平台架構。

平台識別碼的值可以包含一字串，其指明作業系統或執行環境與該UE的相關版本資訊及硬體架構。 可以提供格式的進一步定義與平台識別碼的值，以指示硬體架構及作業系統或執行環境資訊，以獨特地識別在該UE上的適當應用。
用於UE_Profile節點的格式之進一步規格或平台識別碼可以是特定硬體、作業系統、或軟體架構的因數。例如，平台識別碼可以指明以下之一值：
-在x86為基之處理器上的x86的Android
-在x86為基之處理器上的ARM上的Android
-在x86為基之處理器上的Windows版本8
-在ARM為基之處理器上的Windows版本8
-在ARM為基之處理器上的iOS
雖然前述識別碼例值係特定於某些裝置實施法，但這些例示值係提供作例示目的並不是作限定用。各種其他裝置硬體、作業系統、及軟體實施值可以為平台識別碼或在UE_Profile節點結構500中之其他資訊所指明。這些可以包含特定於可架構、可適應、或可更新的硬體及軟體架構的值。
在其他例子中，ISRP可以被架構以管理用以提供分配規則之更新的更新策略，包含用於各種UE及UE應用的設定檔資訊的更新。
節點：<X>/ISRP/<X>/UpdatePolicy
更新策略葉指示用於ISRP的更新策略。更新策略值可以為該UE所用以當該規則不再為該UE所認為有效時，決定是否要求更新其ISRP。如果此葉並未提 供，則可用預設值0。
-發生：ZeroOrOne

圖6提供例示流程圖600，其顯示用以建立及佈署應用指明的ANDSF策略的方法。如所示，流程圖600包含在ANDSF伺服器及在UE執行之動作的組合。然而，明顯地，對以下概觀方法的各種變化可以包含排除在ANDSF伺服器或UE執行的對應動作與技術。
流程圖600描繪傳遞及取得UE設定檔資訊的操作，包含提供來自UE的UE設定檔資訊給ANDSF伺服器(操作602)並由UE設定檔資訊決定在ANDSF伺服器的裝置架構資訊(操作604)。UE設定檔資訊可以以ANDSF MO物件或在佈署ISRP策略之前以其他提供給該ANDSF伺服器的資料被傳遞。
再者，決定特定ISRP策略的值的操作包含根據裝置架構資訊更新該ISRP(操作606)，及提供來自ANDSF伺服器的ISRP給該UE(操作608)。ISRP可以被傳遞為傳遞至UE的ANDSF MO物件的節點。ISRP可以被推入或由ANDSF伺服器推出或EPC的其他服務。
ISRP被更新以成為UE的硬體及軟體架構的因數，但也可以提供可應用的多數類型的卸載策略。決定在 ISRP中之適當組的策略值可以包含決定是否無縫或非無縫為基之話務卸載正發生(操作610)。於選擇在ISRP中的適當組策略值的同時，用於卸載的應用策略值可以由ISRP抽出(操作612)(例如，由特定於無縫或非無縫為基之卸載的ISRP部中的APP-ID節點)。
雖然前述例子係參考於3GPP網路中的特定ANDSF伺服器及策略使用加以提供，但應了解的是，用於網路卸載的識別應用資訊的使用與佈署可以提供在各種網路中並使用其他類型的佈署機制。例如，非ANDSF結構可以用以傳遞用於特定軟體應用的策略資訊的全部或部份。再者，多模使用者設備可以包含能在主要載波網路及次要卸載網路上通訊的任何裝置，包含個人電腦、筆記型電腦及膝上型電腦、智慧手機、平板電腦、行動熱點、媒體播放器、及類似物。
如於此所述，各種方法或技術，或某些態樣或其部份可以採程式碼(即指令)的形式實施在有形媒體，例如快閃記憶體、CD/DVD-ROM、硬碟機、攜帶式儲存裝置、或任何其他機器可讀取儲存媒體中，其中當程式碼被載入並為例如電腦的機器所執行時，機器變成可以實施各種技術的設備。在可程式電腦上執行程式碼的例子中，計算裝置可以包含處理器、可為該處理器讀取之儲存媒體(包含揮發及非揮發記憶體及/或儲存單元)、至少一輸入裝置及至少一輸出裝置。可以實施或利用於此所述之各種技術的一或更多程式可以使用應用規劃介面 (API)、可再使用控制及類似物。此等程式可以實施為高階程序或物件導向規劃語言，以與電腦系統相通訊。然而，如果想要的話，程式可以實施為組合或機器語言實現。在任何情形下，該語言可以為編譯或解譯語言，並組合硬體實施法。
