本文中揭示協定轉換器(PC)的實施例及相關技術。在一些實施例中,一種PC可包括:接收邏輯,其用以接收藉由一應用程式功能(AF)所傳輸之可延伸標示語言(XML)資料;轉換邏輯,其用以將該XML資料轉換成一直徑協定(DP)訊息;以及提供邏輯,其用以提供該DP訊息以供傳輸至一策略及計費規則功能(PCRF)。可揭示及/或主張其他實施例。
Description
本申請案主張2013年4月26日申請且題為「ADVANCED WIRELESS COMMUNICATION SYSTEMS AND TECHNIQUES」的美國臨時申請案第61/816,662號之優先權,該案之全文據此以引用之方式併入本文中。
本發明之實施例大體上係關於無線通訊,且更特定而言,係關於直徑/可延伸標示語言(XML)協定轉換技術。
直徑協定(DP)為用於一些電腦網路中之鑑認、授權及賬戶處理協定。在第三代合作夥伴計劃(3GPP)無線通訊標準中,DP用以在應用程式功能(AF)與策略及計費規則功能(PCRF)之間發送訊息。AF為提供使用網際網路協定(IP)承載資源之應用程式的元件,且通常包括第三方網路應用程式提供者。PCRF為支援策略控制決策制定及基於流量之計費控制功能性的元件,且可使用來自訂用資料庫之資訊作為策略及計費控制決策的基礎。經由Rx介面傳輸AF與
PCRF之間的DP訊息。然而,第三方網路應用程式提供者相較於DP常常更熟悉可延伸標示語言(XML)協定,因此要求AF傳輸訊息可抑制AF發展。
依據本發明之一實施例,係特地提出一種協定轉換器(PC),其包含:接收邏輯,其用以接收藉由一應用程式功能(AF)所傳輸之可延伸標示語言(XML)資料;轉換邏輯,其用以將該XML資料轉換成一直徑協定(DP)訊息;以及提供邏輯,其用以提供該DP訊息以供傳輸至一策略及計費規則功能(PCRF);其中該XML資料包括一屬性值對(AVP)元素,且該AVP元素包括一AVP參數元素,該AVP參數元素包括表示一AVP碼的一第一XML元素、表示一AVP旗標的一第二XML元素,及表示一AVP長度的一第三XML元素。

本文中揭示協定轉換器(PC)的實施例及相關技術。在一些實施例中,PC可接收藉由應用程式功能(AF)傳輸的可延伸標示語言(XML)資料,且可至少部分基於接收到之XML資料產生直徑協定(DP)訊息以供傳輸至策略及計費規則功能(PCRF)。在一些實施例中,PC可自PCRF接收DP訊息,且可至少部分基於接收到之DP訊息產生XML資料以供傳輸至AF。XML資料(藉由PC接收及/或產生)可包括屬性值對(AVP)元素,且AVP元素包括AVP參數元素,該AVP參數元素可包括表示屬性值對(AVP)碼的第一XML元素、表示AVP旗標的第二XML元素,及表示AVP長度的第三XML元素。
本文中所揭示之PC可將XML資料映射至DP訊息(及/或可將DP訊息映射至XML資料)。此情形可使得AF能夠將XML資料而非DP訊息傳輸至PCRF。由於XML協定可為第三方網路應用程式提供者更熟悉的,因此傳輸XML資料而非DP訊息的能力可促進網路應用程式的開發。另外,藉由提供XML資料與DP訊息之間的轉換功能性,本文中所揭示之PC可使得AF能夠傳輸XML資料而不需要PCRF理解XML資料,藉此減少對現有基於DP之PCRF發信號機制的擾亂。
在一些實施例中,藉由AF傳輸至PC(以供提供至PCRF)之XML資料可根據XML綱要經格式化,該綱要使得能夠將XML資料迅速轉換成DP訊息。此等格式中之一些可具有特別有效之轉換性質,該等轉換性質減少必須在AF與PC之間傳送以便形成有效DP訊息的資料之量。此等格式可利用XML綱要之各種性質以提供有效效能。類似地,經組配用於將DP訊息轉換成XML資料的PC可將此綱要用於基於DP訊息產生XML資料以正式地將資訊自PC傳送至AF。用於將XML資料轉換至DP訊息之技術的數個實例揭示於本文中,此等技術中之任一者的互補技術可易於被實施以將DP訊息轉換成XML資料。類似地,用於將DP訊息轉換至XML資料之技術的數個實例揭示於本文中,此等技術中之任一者的互補技術可易於被實施以將XML資料轉換成DP訊息。
各種操作以對理解所主張標的物最有幫助之方

出於本發明之目的,片語「A及/或B」意謂(A)、(B)或(A及B)。出於本發明之目的,片語「A、B及/或C」意謂(A)、(B)、(C)、(A及B)、(A及C)、(B及C)或(A、B及C)。描述可使用片語「在一實施例中」或「在數個實施例中」,其可各自係指相同或不同實施例中之一或多者。此外,如關於本發明之實施例使用的術語「包含」、「包括」、「具有」及其類似者為同義的。
如本文中所使用,術語「邏輯」可係指以下各者、係以下各者之部分或包括以下各者:特殊應用積體電路(ASIC)、電子電路、執行一或多個軟體或韌體程式的處理器(共用、專用或群組)及/或記憶體(共用、專用或群組)、組合邏輯電路及/或提供所描述功能性的其他合適的硬體組件。

圖3為根據各種實施例之DP訊息300的示意性表示。在一些實施例中,DP訊息300可由PC 104之轉換邏輯204(基於由接收邏輯202接收之XML資料)產生,且由提供
邏輯206提供以供傳輸至PCRF 106。在一些實施例中,DP訊息300可由接收邏輯202接收,且由轉換邏輯204轉換成XML資料。DP訊息300之形式可為習知的,且此處經簡要描述以輔助解釋。
可為請求訊息或回覆訊息(諸如,AARequest或AAAnswer訊息)的DP訊息300可包括標頭302,及一或多個屬性值對(AVP)304。如圖3中所展示,標頭302在前32個位元中可包括版本欄位及訊息長度欄位。標頭302之接下來32個位元可包括數個旗標,諸如請求(R)旗標、可代理(P)旗標、錯誤(E)旗標及潛在重新傳輸訊息(T)旗標。R旗標在被設定時指示DP訊息300為請求(且否則為回覆)。P旗標在被設定時指示DP訊息300可經代理、中繼或重新導向(且否則必須在本端處理)。E旗標在被設定時指示DP訊息300含有協定錯誤。T旗標在被設定時指示鏈路故障接管程序已發生。標頭302亦可包括命令碼欄位、應用程式ID欄位、逐躍ID欄位及端對端ID欄位。
包括於DP訊息300中之一或多個AVP 304可提供額外資料。在一些實施例中,DP訊息300必須包括至少一AVP 304。圖4為根據各種實施例之AVP 400的示意性表示。在一些實施例中,AVP 400可包括於DP訊息300中。AVP400之形式可為習知的,且此處經簡要描述以輔助解釋。
AVP 400可包括標頭402及資料404。如圖4中所展示,AVP 400之前32個位元可為AVP碼欄位。AVP 400之接下來32個位元可包括數個旗標,諸如廠商特定(V)旗標、強
制(M)旗標及受保護(P)旗標。V旗標在被設定時指示AVP 400在位元64至95中包括廠商ID欄位。M旗標在被設定時指示對AVP 400之支援對於待接受之DP訊息300為需要的。P旗標在被設定時指示對端對端加密的需要。AVP 400之接著32個位元亦可包括AVP長度欄位。如圖4中所展示,AVP 400亦可包括廠商ID欄位(如上文所論述)及資料404。
圖5為根據各種實施例之XML資料500的示意性表示。在一些實施例中,XML資料500可由PC 104之接收邏輯202接收,且由轉換邏輯204轉換成DP訊息。在一些實施例中,XML資料500可由轉換邏輯204(基於由接收邏輯202接收之DP訊息)產生,且由提供邏輯206提供以供傳輸至AF 102。
XML資料500可包括一或多個元素。如圖5中所展示,XML資料500可包括元素502、504、506、508、510及512。一些元素(諸如,元素502及512)可為獨立元素,且可能既不巢套於其他元素中,亦可能不包括巢套元素。諸如元素504及508)之一些元素可包括額外巢套元素。在圖5中,元素504包括巢套元素506、508及510。元素510係雙重巢套於元素504內,此係因為元素510包括於元素508中,且元素508包括於元素504中。
在接收邏輯202經組配以接收由AF 102傳輸之XML資料且轉換邏輯204經組配以將XML資料轉換成DP訊息的一些實施例中,可使用預定格式來組織XML資料。此格式可由AF 102及PC 104所已知的XML綱要來定義。本文
中揭示數個此種格式。此等格式中的各種格式可由轉換邏輯204來辨識,且可使得轉換邏輯204能夠將XML資料有效地轉換成DP訊息。
在一些實施例中,由接收邏輯202自AF 102接收的XML資料可包括AVP元素。XML資料之AVP元素可對應於DP訊息之AVP(例如,DP訊息300之AVP 400)。在一些實施例中,轉換邏輯204可將包括於接收到之XML資料之AVP元素中的資料轉換成DP訊息之AVP的分量(以供由提供邏輯206提供至PCRF 106)。
在一些實施例中,包括於XML資料中之AVP元素可包括一或多個額外元素。舉例而言,AVP元素可包括表示AVP碼的元素。AVP元素可包括表示一或多個AVP旗標的元素。AVP元素可包括表示AVP長度的元素。在一些實施例中,包括於XML資料中之AVP元素可包括表示APV碼的元素,及表示一或多個AVP旗標的元素,以及表示AVP長度的元素。包括於AVP元素中之此等元素中的每一者可對應於DP訊息之AVP的分量。舉例而言,轉換邏輯204可經組配以識別包括於表示AVP碼之元素中的資料,且將彼資料(或其等效物)提供於AVP 400的AVP碼欄位中。轉換邏輯204可經組配以識別包括於表示一或多個AVP旗標之元素中的資料,且將彼資料(或其等效物)作為旗標提供於AVP 400中。轉換邏輯204可經組配以識別包括於表示AVP長度之元素中的資料,且將彼資料(或其等效物)提供於AVP 400之AVP長度欄位中。
在一些實施例中,AVP元素可包括AVP參數元素,該元素自身包括表示AVP碼之元素、表示一或多個AVP旗標的元素,及表示AVP長度的元素。換言之,表示AVP碼之元素、表示一或多個AVP旗標的元素及表示AVP長度的元素可巢套於AVP參數元素中,該AVP參數元素可巢套於AVP元素中。以此方式,AVP參數元素可將表示AVP碼、一或多個AVP旗標及AVP長度的數個元素「分群」。在一些實施例中,包括於XML資料中之AVP參數元素可採用下文展示於下表1中的形式。
如所展示,表1之AVPParameters元素包括表示AVP碼之元素及表示AVP旗標的元素,以及表示AVP長度的元素。在一些實施例中,包括於由接收邏輯202接收之XML資料中的每一有效AVP元素可包括AVP參數元素(例如,表1之AVPParameters元素),其包括1)表示AVP碼的元素、2)表示一或多個AVP旗標的元素,3)及表示AVP長度的元素。根據定義有效AVP元素之XML綱要,AVP參數元素可為AVP元素的所需元素。
在一些實施例中,AVP元素可藉由XML綱要中之參考屬性而包括於XML資料中。舉例而言,表2包括可對應
於提供會話ID資訊(例如,對應於DP之AVP碼260之會話Id元素)之AVP的XML資料。舉例而言,SessionID AVP可包括於經由Rx介面傳輸之AARequest訊息中。
如表2中所展示,SessionIDAVP元素藉由參考屬性而包括表1的AVPParameter元素。相較於針對XML綱要中之每一代表性AVP元素顯式地將元素包括於AVP參數(例如,碼、旗標及長度元素)中,使用AVP參數元素可減少DP訊息之XML表示的大小。在一些實施例中,包括於XML資料中之每一有效AVP元素可包括AVP參數元素。
展示於表2中之SessionIDAVP元素僅為可包括於XML資料中且在基於XML資料產生DP訊息時藉由轉換邏輯204辨識的AVP元素的說明性實例。以下表3列出可包括於由AF 102提供之XML資料中的AVP元素的數個實例。在表3之第一欄中,呈現對應於DP中之已知AVP類型的AVP類型之清單。在表3之第二欄中,呈現與已知AVP類型中之每一者相關聯的DP碼。在表3之第三欄中,呈現每一已知AVP類型之已知DP資料類型。在表3之第四欄中,呈現XML綱要中對應於不同的已知AVP類型的AVP元素之資料類型。表3之第四欄中呈現的資料類型可提供與呈現於表3之第三欄
中之資料類型的合適匹配,從而使得能夠在XML中傳達AVP資訊且將其轉換成DP訊息中的AVP。
一些DP AVP可包括其他AVP或與其他AVP相關聯。以下表4列出與可包括於藉由AF 102提供之XML資料中的媒體組件描述AVP相關聯之AVP元素的數個實例。表4之欄如上文參考表3所描述而定義。
以下表5列出與可包括於藉由AF 102提供之XML資料中的訂用ID AVP相關聯之AVP元素的數個實例。

以下表10列出與可包括於藉由AF 102提供之XML資料中的CC-Money AVP相關聯之AVP元素的數個實例。
以下表11呈現可對應於DP訊息之標頭(例如,圖3之DP訊息300之標頭302)的XML資料之元素。藉由接收邏輯202接收之XML資料可包括表11之XML資料元素,且轉換
邏輯204可將表11之XML資料元素轉換成將包括於供傳輸至PCRF 106之DP訊息中的DP標頭。
以下表12呈現可對應於DP之各種AVP的XML資料之AVP元素。由接收邏輯202接收之XML資料可包括表11之AVP元素中的一或多者,且轉換邏輯204可將XML資料之AVP元素轉換成將包括於供傳輸至PCRF 106之DP訊息中的AVP。表12中之每一AVP元素可轉換成的AVP藉由XML元素之名稱來識別。
如表12中所指示,對應於AVP的XML元素中之每一者可包括AVPParameters元素(其自身可包括表示AVP碼之元素及表示AVP旗標之元素,以及表示AVP長度的元素,如上文所論述)。表12之具有「群組」類型之數個XML元素包括其他XML元素。舉例而言,媒體組件描述元素、訂用ID元素、所支援特徵元素、受贊助連接性資料元素及代理資訊元素可具有群組類型。包括於其他XML元素中的元素亦可具有群組類型。舉例而言,受贊助連接性資料元素可包括授予服務群組元素及使用者服務群組元素,且授予服務群組元素及使用者服務群組元素可各自具有群組類型。在另一實例中,授予服務群組元素及使用者服務群組元素可各自包括金錢群組元素,且金錢群組元素可具有群組類型。
在一些實施例中,參考表1至表12論述之XML表
示可表示由接收邏輯202接收以供由轉換邏輯204轉換成DP訊息之XML資料的有效形式。在一些實施例中,參考表1至表12論述之XML表示可表示由轉換邏輯204基於由接收邏輯202接收之DP訊息而產生之XML資料的形式。XML資料元素與DP訊息之分量之間的映射係在表1至表12中識別。參考表1至表12論述之XML表示並非詳盡的,且額外XML資料元素可根據說明於表1至表12中之型樣及本文中所論述的技術經定義以對應於額外DP訊息分量。
圖6及圖7為根據各種實施例的可由PC 104執行之例示性程序的流程圖。在一些實施例中,PC 104可經組配以執行說明於圖6中的程序及說明於圖7中的程序。在一些實施例中,PC 104可經組配以執行說明於圖6及圖7中之程序中的一者,但不執行另一者。
圖6為根據各種實施例的用於基於接收到之XML資料提供DP訊息之例示性程序600的流程圖。在操作602處,PC 104可接收由AF 102傳輸的XML資料。在一些實施例中,操作602可由PC 104的接收邏輯202執行。在一些實施例中,在操作602處接收到之XML資料可採用上文參考表1至表12論述之實施例中之任一者的形式。在一些實施例中,XML資料可包括AVP元素,且AVP元素可包括表示AVP碼的第一XML元素、表示AVP旗標的第二XML元素,及表示AVP長度的第三XML元素。
在操作604處,PC 104可將XML資料(在操作602處接收到)轉換成DP訊息。在一些實施例中,操作604可由
PC 104的轉換邏輯204執行。舉例而言,接收到之XML資料與DP訊息之分量之間的映射可採用上文參考表1至表12論述之實施例中之任一者的形式。
在操作606處,PC 104可將DP訊息(在操作604處產生)提供至PCRF 106。在一些實施例中,操作604可由PC 104的提供邏輯206執行。程序600可接著結束。
圖7為根據各種實施例的用於基於接收到之DP訊息提供XML資料之例示性程序700的流程圖。在操作702處,PC 104可接收由PCRF 106傳輸的DP訊息。在一些實施例中,操作702可由PC 104的接收邏輯202執行。
在操作704處,PC 104可將DP訊息(在操作702處接收到)轉換成XML資料。在一些實施例中,操作704可由PC 104的轉換邏輯204執行。舉例而言,接收到之DP訊息與XML資料元素之間的映射可採用上文參考表1至表12論述之實施例中之任一者的形式。
在操作706處,PC 104可將XML資料(在操作704處產生)提供至AF 102。在一些實施例中,操作706可由PC 104的提供邏輯206執行。在一些實施例中,在操作706處提供之XML資料可採用上文參考表1至表12論述之實施例中之任一者的形式。在一些實施例中,XML資料可包括AVP元素,且AVP元素可包括表示AVP碼的第一XML元素、表示AVP旗標的第二XML元素,及表示AVP長度的第三XML元素。程序700可接著結束。
PC 104在無線通訊系統100中之邏輯位置在不同
實施例中可發生變化。圖8至圖11描繪根據各種實施例的PC在無線通訊系統內的各種配置。
在圖8之配置800中,PC 104可經組配以在包括PCRF 106之直徑範圍內操作。在圖8中,兩個直徑範圍118及120描繪於3GPP公用陸上行動網路(PLMN)122中。直徑範圍118及120中之每一者可包括一或多個PCRF 106、直徑路由代理(DRA)114及PC 104。包括於直徑範圍中之PCRF 106可為可分離定址的,且AF 102與直徑範圍中該等PCRF 106中之特定者之間的會話可藉由DRA 114維持。詳言之,DRA 114可維持用於某使用者裝備(UE)及IP連接性存取網路(IP-CAN)會話的所指派PCRF 106之狀態。除DRA 114與PC 104之間的通訊外,DRA 114亦可如3GPP無線通訊標準中所描述根據習知DRA來組配。AF 102可經組配以在AF網域116內操作。在配置800中,PC 104可經組配以經由通訊鏈路108自AF 102接收XML資料,且將XML資料轉換成一或多個DP訊息以供經由通訊鏈路112提供至DRA 114。DRA 114可將DP訊息投送(經由通訊鏈路124)至適當PCRF 106。在一些實施例中,配置800之PC 104可經組配以自PCRF 106接收一或多個DP訊息(經由DRA 114以及通訊鏈路124及112),且將一或多個DP訊息轉換成XML資料以供提供至AF 102(經由通訊鏈路108)。在一些實施例中,通訊鏈路108、112及124可包括於Rx介面中。
配置800可具有數個優點。藉由將3GPP PLMN 122內之PC 104置放於至3GPP網域之入口點處,可需要對
3GPP架構(在3GPP PLMN 122內)之很少改變或無改變以適應XML資料轉換功能性。第三方應用程式提供者可不需要採用或以其他方式併有額外硬體及/或軟體來實施PC 104,從而實現轉換功能性之快速且容易的採用。因為PC 104包括於3GPP架構中,所以PC 104之操作及特性可經標準化作為3GPP通訊標準的部分,且AF 102與PC 104之間的互動可易於藉由PLMN 122之業者管理。然而,此等優點可相對於在3GPP無線通訊標準內充分指定PC 104之操作及特性所需的額外標準化工作而保持平衡。
在圖9之配置900中,PC 104可經組配以在包括AF 102之網域116內操作。AF 102與PC 104之間的通訊可根據任何所要介面(例如,專屬介面)來執行。在一些實施例中,AF 102與PC 104之間的通訊可以與針對用於表示資源清單之XML格式的2007年5月提議之網際網路工程工作小組(IETF)標準一致的方式執行。在配置900中,PC 104可經組配以經由通訊鏈路108自AF 102接收XML資料,且將XML資料轉換成一或多個DP訊息以供經由通訊鏈路112提供至DRA 114。DRA 114可將DP訊息投送(經由通訊鏈路124)至適當PCRF 106。在一些實施例中,配置800之PC 104可經組配以自PCRF 106接收一或多個DP訊息(經由DRA 114以及通訊鏈路124及112),且將一或多個DP訊息轉換成XML資料以供提供至AF 102(經由通訊鏈路108)。在一些實施例中,通訊鏈路112及124可包括於Rx介面中。配置900之其他組件可採用上文參看圖8描述之對應組件的形式。
配置900可具有數個優點。藉由將PC 104置放於AF網域116內,需要執行很少或不需要執行標準化工作來將PC 104之功能性併入至3GPP無線通訊標準中,從而卸下對第三方AF網域116的實施。然而,第三方應用程式提供者必須實施PC 104的功能性,此情形可藉由允許將XML資料代替DP訊息傳輸至PC 104而損害所獲得的益處。將PC 104定位於AF網域116中可開啟PC 104之許多非標準化變體的可能性,此情形可使得使用此PC 104之AF 102的管理更複雜。另外,由於配置900之PC 104可伺服一個以上直徑範圍(例如,直徑範圍118及120),因此PC 104可需要定址功能性以將資訊投送至適當直徑範圍及/或自適當直徑範圍投送資訊。
在圖10之配置1000中,PC 104可經組配以在AF網域116及PLMN 122外操作。在配置1000中,PC 104可「橋接」AF網域116與藉由PLMN 122表示的3GPP網域。在配置1000中,PC 104可經組配以經由通訊鏈路108自AF 102接收XML資料,且將XML資料轉換成一或多個DP訊息以供經由通訊鏈路112提供至DRA 114。DRA 114可將DP訊息投送(經由通訊鏈路124)至適當PCRF 106。在一些實施例中,配置800之PC 104可經組配以自PCRF 106接收一或多個DP訊息(經由DRA 114以及通訊鏈路124及112),且將一或多個DP訊息轉換成XML資料以供提供至AF 102(經由通訊鏈路108)。在一些實施例中,通訊鏈路112及124可包括於Rx介面中。配置1000之其他組件可採用上文參看圖8描述之對應
組件的形式。
配置1000可具有數個優點。藉由將PC 104置放於PLMN 122外,需要執行很少或不需要執行標準化工作以將PC 104之功能性併入至3GPP無線通訊標準中。另外,第三方應用程式提供者可不需要採用或以其他方式併有額外硬體及/或軟體來實施PC 104,從而實現轉換功能性之快速且容易的採用。然而,將PC 104定位於PLMN 122外可開啟PC 104之許多非標準化變體的可能性,此情形可使得使用此PC 104之AF 102的管理更複雜。另外,由於配置1000之PC 104可伺服一個以上直徑範圍(例如,直徑範圍118及120),因此PC 104可需要定址功能性以將資訊投送至適當直徑範圍及/或自適當直徑範圍投送資訊。
在圖11之配置1100中,多個PC(104a、104b及104c)可經組配以在不包括PCRF 106之直徑範圍126內操作。在圖11中,三個直徑範圍118、120及126描繪於PLMN 122內。直徑範圍118及120中之每一者可包括一或多個PCRF 106及一DRA 114。包括於直徑範圍118及120中之PCRF 106可為可分離定址的,且AF 102與直徑範圍118及120中之該等PCRF 106中之特定者之間的會話可藉由DRA 114維持(如上文參看圖8所論述)。AF 102可經組配以與PC 104a、104b及104c中之每一者通訊(經由通訊鏈路108)。PC 104a、104b及104c中之每一者可經組配以與直徑範圍118中之DRA 114及直徑範圍120中之DRA 114通訊。在配置1100中,PC 104a、104b及104c中之任一者可經組配以經由通訊鏈路108
自AF 102接收XML資料,且將XML資料轉換成一或多個DP訊息以供經由通訊鏈路112提供至(直徑範圍118或直徑範圍120的)DRA 114。DRA 114可將DP訊息投送(經由通訊鏈路124)至適當PCRF 106。在一些實施例中,配置1100之PC 104a、104b及104c中之任一者可經組配以自PCRF 106接收一或多個DP訊息(經由對應DRA 114以及通訊鏈路124及112),且將一或多個DP訊息轉換成XML資料以供提供至AF 102(經由通訊鏈路108)。在一些實施例中,通訊鏈路108、112及124可包括於Rx介面中。
配置1100可具有數個優點(例如,上文參看圖8所描述之彼等優點),但可相對於在3GPP無線通訊標準內充分指定PC 104a、104b及104c之操作及特性所需的額外標準化操作而保持平衡。
圖12為實例計算裝置1200的方塊圖,該計算裝置可適用於實踐各種所揭示實施例。舉例而言,計算裝置1200可充當AF 102、PC 104、PCRF 106或本文中所論述之任何其他合適裝置或以其他方式支援AF 102、PC 104、PCRF 106或本文中所論述之任何其他合適裝置的操作。計算裝置1200可包括數個組件,該等組件包括一或多個處理器1204及至少一通訊晶片1206。在各種實施例中,處理器1204可包括處理器核心。在各種實施例中,至少一通訊晶片1206亦可實體且電耦接至處理器1204。在其他實施中,通訊晶片1206可係處理器1204之部分。在各種實施例中,計算裝置1200可包括PCB 1202。對於此等實施例,處理器1204及
通訊晶片1206可安置於PCB 1202上。在替代實施例中,各種組件可在不使用PCB 1202情況下進行耦接。在一些實施例中,計算裝置1200可為伺服器計算裝置,或處理資料的任何其他電子裝置。詳言之,在一些實施例中,提供PC 104之計算裝置1200可為伺服器計算裝置,其能夠經組配以處理所要通訊協定(例如,能夠使負載保持平衡且具有其他常見功能性的網路伺服器)。
計算裝置1200可包括可能或可能不實體且電耦接至PCB 1202的其他組件。此等組件可提供本文中所揭示的各種計算裝置之資料儲存及通訊功能性中的一些或全部(例如,PC 1)。此等其他組件可包括(但不限於)依電性記憶體(例如,動態隨機存取記憶體(DRAM)1208)、非依電性記憶體(例如,唯讀記憶體(ROM)1210)、一或多個硬碟機、一或多個固態磁碟機、一或多個緊密光碟機及/或一或多個數位影音光碟機)、快閃記憶體1212及輸入/輸出控制器1214、數位信號處理器(圖中未示)、密碼處理器(圖中未示)、圖形處理器1216、一或多個天線1218(其可充當(例如)天線208)、觸控式螢幕顯示器1220、觸控式螢幕控制器1222、其他顯示器(諸如,圖中未示的液晶顯示器、陰極射線管顯示器、電子墨水顯示器)、電池1224或其他電源供應器、音訊編碼解碼器(圖中未示)、視訊編碼解碼器(圖中未示)、全球定位系統(GPS)裝置1228、羅盤1230、加速度計(圖中未示)、迴轉儀(圖中未示)、揚聲器1232、攝影機1234、任何其他所要感測器(圖中未示)等等。在各種實施例中,處
理器1204可與其他組件一起整合於同一晶粒上以形成系統單晶片(SoC)。
在各種實施例中,依電性記憶體(例如,DRAM 1208)、非依電性記憶體(例如,ROM 1210)、快閃記憶體1212及大容量儲存裝置可包括程式設計指令,該等指令經組配以使得計算裝置1200能夠回應於由處理器1204進行的執行而實踐本文中所描述之程序的所有或選定態樣(例如,XML資料接收及/或DP訊息接收、轉換操作及/或XML資料及/或DP訊息提供)。舉例而言,諸如依電性記憶體(例如,DRAM 1208)、非依電性記憶體(例如,ROM 1210)、快閃記憶體1212及大容量儲存裝置的記憶體組件中之一或多者可為包括指令之臨時及/或永久(例如,非暫時性)複本的機器可讀媒體,該等指令複本在由一或多個處理器1204執行時使得計算裝置1200能夠實踐本文中所描述之程序的所有或選定態樣(諸如,PC 104之接收邏輯202、轉換邏輯204及/或提供邏輯206的功能性)。計算裝置1200可存取的記憶體可包括為上面安裝有計算裝置1200之裝置之實體部分的一或多個儲存資源,及/或可由計算裝置1200存取但未必為計算裝置1200之部分的一或多個儲存資源。舉例而言,儲存資源可由計算裝置1200經由通訊晶片1206在網路上存取。此等記憶體裝置中之任何一或多者可包括於PC 104的記憶體208中。
通訊晶片1206可實現用於至及自計算裝置1200之資料之傳送的有線及/或無線通訊。術語「無線」及其衍
生詞可用以描述可經由使用經由非固態媒體調變之電磁輻射傳達資料的電路、裝置、系統、方法、技術、通訊頻道等。術語並不暗示相關聯裝置不含有任何導線,但在一些實施例中,相關聯裝置可能不含有導線。如上文所提到,本文中所描述之許多實施例可供WiFi及3GPP/LTE通訊系統使用。然而,通訊晶片1206可包括任何一或多個通訊晶片,該一或多個通訊晶片經組配以實施數個無線標準或協定中之任一者以提供數種無線電存取技術中的任一者。計算裝置1200可包括多個通訊晶片1206。舉例而言,第一通訊晶片1206可專用於諸如Wi-Fi及藍芽之較短距離(range)無線通訊,且第二通訊晶片1206可專用於諸如GPS、EDGE、GPRS、CDMA、WiMAX、LTE、Ev-DO及其他者的較長距離無線通訊。
