Description

在漫遊情境中的無線區域網路之選擇規章的控制技術
本文所描述的實施例一般係涉及無線網路和通信系統。
發明背景
在LTE(長期演進)蜂巢式系統中，如在第三代合作夥伴計劃(3GPP)的LTE規範中所闡述的，一終端機(在LTE系統中一終端機被稱為使用者設備或UE)獲取蜂巢式網路接取的方式為連接到一個隸屬於一運營商或服務供應商的公共陸地行動網路(PLMN)。到該PLMN的連接係由一基地台(在LTE系統中被稱作一演進型節點B或eNB)所提供。除了如此的蜂巢式網路接取之外，所謂的雙模式UE還包含有的功能為可同時透過一無線區域網路(WLAN)，通常稱為WiFi，來獲得網路接取。在一漫遊情境中，該UE係從一非其本籍運營商之運營商處獲取蜂巢式網路接取，該雙模UE可選擇把IP(網際網路協定)資料流路由經該蜂巢式網路或是路由經一個或多個WLAN。該本籍運營商(被稱為本籍PLMN或HPLMN)比起該客籍運營商(被稱為該客籍PLMN或VPLMN)在此考量方面可能已經有優先權。
目前的3GPP規範描述了在不同的漫遊情境中在HPLMN和VPLMN之間偏好的順序和優先權，其係基於兩種應被滿足的基本架構原則：(a)該HPLMN控制由該UE所選擇的該服務PLMN，以及(b)若有衝突，由該VPLMN所提供的規章會優先於該HPLMN所提供的規章。該第一原則賦予該本籍運營商在選擇蜂巢式接取方面的優先權，而該第二原則所基礎的假設為該VPLMN對於入境的漫遊使用者在WLAN網路選擇方面應有最後的發言權，因為他們使用的是該VPLMN資源。
發明概要
依據本發明之一實施例，係特地提出一種使用者設備(UE)裝置，該裝置包含有：處理電路和一用以進行蜂巢式以及WLAN(無線區域網路)接取的無線電收發機，其中該處理電路將：當網路接取已從一客籍蜂巢式運營商獲取並亦可從一個或多個WLAN獲取時，檢索一設置，該設置指出當在蜂巢式與WLAN(無線區域網路)接取之間進行切換時是否偏好IP(網際網路協定)位址保留；以及如果沒有指出對IP位址保留的偏好，則會偏好選擇接收自一H-ANDSF(本籍運營商ANDSF)伺服器之ANDSF(接取網路和發現選擇功能)資訊所指出的網路選擇和路由規章，而非接收自一V-ANDSF(客籍運營商ANDSF)伺服器之資訊所指出者。

較佳實施例之詳細說明
以上所討論的架構原則被引入至3GPP時並沒有非無縫WLAN卸載(NSWO)、沒有透過WLAN基於S2a的連接(信任的WLAN接取)、並且與WLAN服務供應商間的漫遊關係在很大程度上並不到位。因此有必要全面改革這些規則，並在漫遊情景中基於HPLMN的偏好在WLAN的選擇控制中引入更多的靈活性。請注意，若僅使該UE偏好選擇HPLMN規則將可滿足架構原則(a)，但不滿足原則(b)。在另一方面，若UE偏好選擇VPLMN規則，則該解決方案將滿足架構原則(b)中，但不滿足原則(a)。
接取網路發現和選擇功能(ANDSF)是在LTE網路中的一種功能，若處於一些非3GPP接取網路可供使用的情況下，一營運商可以用該功能來控制UE在不同接取技術之間的優先順序，並且也可以輔助裝置來發現可用的接取網路。本發明所描述的解決方案可用於在一VPLMN的ANDSF(被稱為一客籍ANDSF或VANDSF)和一HPLMN的ANDSF(被稱為一本籍ANDSF或HANDSF)之間建立該優先順序，並在當HPLMN仍然掌控PLMN選擇時可啟用該VPLMN來驅動WLAN選擇。基礎於該WLAN接取類型以及在不同的情境下同時滿足架構限制(a)和(b)之資源的可能使用方式，本發明所描述的解決方案加強了ANDSF並在 HPLMN/VPLMN控制的適用範圍中引入了靈活性。該等加強讓一服務供應商可控制那一些運營商可在WLAN漫遊情境中被選中，因此它可針對部署的WLAN網路控制在漫遊情況中的業務。
漫遊意味著該正在漫遊的雙模UE正使用由該3GPP運營商所提供的蜂巢式服務，但對於基於其他Wi-Fi服務之Wi-Fi接取側來說，該UE實際上可能是非漫遊的。該雙模UE然後會使用該VANDSF，其為由該蜂巢式VPLMN所營運的該ANDSF。從3GPP的角度來看，屬於Wi-Fi漫遊合作夥伴的該ANDSF或其他規章伺服器是在範圍外的。在這些情況下，該ANDSF亦會選擇該Wi-Fi服務供應商。Wi-Fi網路選擇/路由規章使用VANDSF的正當性會在跨越Wi-Fi和蜂巢式接取時需要有IP位址保留的一些情境中被找到。在這些情境中，該VANDSF可以提供在Wi-Fi網路選擇和路由規章上更好的指引。因此，在一實施例中，該VANDSF會被使用於網路選擇和路由規章只有當一雙模UE和VPLMN支援SaMOG(透過GTP(通用封包無線電服務通道協定)之基於S2a的移動)或者該UE設置(透過本籍運營商或使用者偏好)表明了一種對SaMOG或IP位址保留的偏好。
當非無縫WLAN卸載(NSWO)是該HPLMN或該使用者的首選時，則沒有提供跨越Wi-Fi之IP位址保留，而且蜂巢式接取和流量將透過Wi-Fi被直接路由到網際網路。在NSWO的情況下，該使用者可以漫遊在該蜂巢式接取上但在家裡可漫遊在Wi-Fi上，或漫遊在Wi-Fi而非蜂巢式 VPLMN的不同漫遊合作夥伴上。因此，在一實施例中，在這樣的情況下，Wi-Fi接取網路/服務供應商和路由規章的選擇是基於該HPLMN的ANDSF規章，因為該蜂巢式VPLMN可能會誤導該UE來使用該特定VPLMN所偏好的Wi-Fi網路，當其可能異於該HPLMN的偏好時。
系統說明
圖1圖示出一示例漫遊情景境，其中一UE 100已經從一VPLMN 120獲得蜂巢式網路接取，並可透過一個或多個WLAN 130和140另外地獲得網路接取。該UE 100包含有用以進行WLAN和蜂巢式網路接取的處理電路101和一雙模式RF(射頻)收發器(或多個收發器)。該UE 100透過一RF通信鏈路與一VPLMN 120的eNB 121進行通信，有時也被稱為該LTE無線或空氣介面。該eNB 121提供連接到該VPLMN的演進封包核心(EPC)，它的(在該使用者平面)主要組件為S-GW 122(伺服閘道)和P-GW 123(封包資料網路(PDN)閘道)。該P-GW是該EPC與外界的接點並與一個或多個封包資料網路諸如該網際網路交換資料，而該S-GW充當在該eNB和P-GW之間的一路由器。
該UE 100還可以透過WLAN 130和140獲得網路接取，它們每一個都能夠透過直接的網際網路接取提供連接到該網際網路150。當UE 100已經同時透過VPLMN 120和WLAN 130和140的一個或多個來獲得網路接取時，它可以把IP流量以一種方式卸載到任意一個WLAN使得該卸載 的IP流量不會橫越過該VPLMN的EPC，用一種所謂的非無縫WLAN卸載(NSOW)程序。使用NSOW卸載的IP流量並不會為會談連續性提供IP位址保留，因為該EPC的移動性錨點並沒有被維持。WLAN 140被圖示為一不受信任的網路，並只能提供NSOW。在另一方面，WLAN 130，被圖示為一受信任的網路。因此，該VPLMN可以經由一S2a介面在WLAN 130和P-GW 123之間提供直接連接，使得從WLAN來的IP流量會被路由經VPLMN 120的該EPC。當UE 100被同時連接到該VPLMN 120和WLAN 130時，該S2a介面因此能夠提供可為會談連續性提供IP位址保留的WLAN卸載，有時也被稱為是SaMOG(透過GTP(通用封包無線電服務通道協定)之基於S2a的移動)。流量也可以無IP位址保留的方式被路由經該S2a介面。
如在圖1中所示，如果該VPMLN 120支援透過EPC的SaMOG和S2a接取，而該UE 100較偏好該類型的接取時，則該UE應該基於該VPLMN的規章選擇一WLAN，因為只有該VPLMN知道哪些WLAN被配置成支援具有S2a連接的EPC接取。這可以是在每一WLAN AP(應用協定)的基礎上或每一SSID(服務集合識別碼)的基礎上。所以在這種情況下，該HPLMN的偏好不應套用於WLAN的選擇。在另一方面，如果該UE偏好執行NSWO，則該選擇的WLAN並不須要支援與該VPLMN的任何特定互連機制。事實上，任何WLAN可被使用來建立連接，只要它提供有網際網路接取的話。所以該UE然後能夠基於該HPLMN偏好選擇一 WLAN，並且在這種情況下可以覆蓋VPLMN偏好。該UE是否應該覆蓋該VPLMN偏好可以透過該HPLMN來控制。
該UE 100從一隸屬於該UE本籍運營商HPLMN160的本籍ANDSF(H-ANDSF)伺服器165和由該VPLMN120所營運的一客籍ANDSF(V-ANDSF)伺服器125獲取ANDSF資訊。傳送給該UE的ANDSF資訊為一運營商提供了一個可用於操縱該UE優先使用特定網路做接取的工具。由一ANDSF伺服器提供給該UE的該ANDSF資訊可能包含有以下的內容：接取網路發現和選擇資訊、系統間的移動規章(ISMP)、以及系統間的路由規章(ISRP)。該接取網發現和選擇資訊包含有在該UE附近的一可供使用的接取網路列表，其包括3GPP網路和其他諸如WLAN的類型。該資訊可能包含有接取技術類型以及有效性的條件(例如，在何地和何時該資訊是有效的)。ISMP是一組運營商定義的規則和偏好，其會影響由該UE所做的系統間移動性決定，包括有關於是否使用3GPP或非3GPP接取的決定，當該UE在同一時間只可以使用一單一無線接取介面時。該等ISRP是一組運營商定義的規則和偏好，其會影響由該UE相對於3GPP或一特定類型的非3GPP接取所採取的該等路由決策，當該UE可同時在多個無線接取介面上路由IP流量時。該ANDSF資訊是由參數值所構成，該等參數值被組織成一種被稱為一ANDSF管理物件(ANDSFMO)的資料結構。一ANDSFMO是一種樹狀結構，其具有內部節點和葉節點，其中該等葉節點包含有該實際參數值而該等內部節點則充當用以組織 該資訊的佔位者。
在一實施例中，如果該UE指出偏好IP位址保留(例如，SaMOG)，則V-ANDSF規章將被優先選用於WLAN網路選擇和路由規章。在另一實施例中，如果UE指出偏好NSWO，則H-ANDSF規章應優先用於WLAN網路選擇和路由規章。在另一實施例中，該VPLMN向該UE指出它是否支援使用S2a的WLAN接取。舉例來說，這可以在該ISRP中以一新的葉節點來達成。在另一實施例中，如果該UE偏好NSWO，並且如果來自該VPLMN的該ISRP規則包括一NSWO規則，則該UE可以基於該HPLMN偏好選擇一WLAN。在其他的情況下，該UE可以僅考慮來自該VPLMN的ISRP規則，正如目前所指定的。在另一實施例中，對於NSWO相關的規則，該HPLMN可以在ANDSF資訊中指出HPLMN規則是否應優先於VPLMN規則。舉例來說，該指出可能偏好HPLMN規章和漠視V-ANDSF NSWO規則，或給予V-ANDSF NSWO規則優先權。該本籍運營商也可以在該ANDSFMO中加入一偏好的服務供應商列表，它們可以在該NSWO情況有優先權。
根據LTE規範，該ANDSFMO的結構被闡明於3GPP TS 24.312中。圖2和圖3分別為3GPP TS 24.312之圖4.2.1和4.2.5的複製，但已經加入了如以以上所述的修改。圖3顯示了該ANDSFMO的一部分，在其上已經被添加了葉節點305和310。葉節點305允許一ANDSF伺服器指出是否其網路供應商支援使用該S2a介面的WLAN接取。葉節點310 允許一H-ANDSF伺服器指出是否該UE應該或不應該遵循NSWO的HPLMN規章。圖2顯示了該ANDSFMO的一部分，在其上已經被添加了葉節點205。葉節點205允許一HPLMN列出它的偏好服務供應商列表，該等供應商係已知於該UE。舉例來說，當遵循HPLMN規章時，該列表可以被使用於NSWO期間。
