Description
本發明屬於通信技術領域，尤其是關於一種按需求為終端選擇移動性管理機制的方法及裝置。 The present invention belongs to the field of communication technology, and particularly relates to a method and device for selecting a mobility management mechanism for a terminal according to demand.
根據3GPP TR 22.891的描述，未來5G網路需要提供不同需求的移動性支持。因為5G網路中存在不同的通信場景：不同的終端具有不同的移動規範，例如有些終端是在高速移動中接入網路的，而另外一些是遊牧接入網路或者靜態接入網路的；不同的業務也具有不同的移動性支持要求，例如某些業務希望減少在業務傳輸過程中的中斷和丟包率，因此要求網路對應用層遮罩移動性事件，包括切換過程中保持IP位址不變，而另外一些應用卻可以使用應用層手段來支持業務連續性。基於這些考慮，3GPP提出了按需求的移動性支持。 According to the description of 3GPP TR 22.891, future 5G networks need to provide mobility support with different requirements. Because there are different communication scenarios in 5G networks: different terminals have different mobile specifications, for example, some terminals access the network during high-speed movement, while others are nomadic access networks or static access networks. ; Different services also have different mobility support requirements. For example, some services want to reduce the interruption and packet loss rate during the service transmission process, so the network is required to mask the mobility events at the application layer, including maintaining IP during the handover process. The address remains the same, while other applications can use application layer methods to support business continuity. Based on these considerations, 3GPP has proposed on-demand mobility support.
目前SA2提出過一種按需求移動性管理的方法(3GPP TR 23.799)，具體要求網路中實現移動性管理控制功能，該控制功能能夠基於終端的簽約等資訊獲取終端的移動性級別。基於終端的移動性級別，移動性管理控制功能配置網路中的移動性管理子功能，啟動需要向終端提供服務的移動性管理子功能，從而為終端提供量身定制的移動性管理機制。 At present, SA2 has proposed a method of on-demand mobility management (3GPP TR 23.799), which specifically requires a network to implement a mobility management control function, which can obtain the terminal's mobility level based on information such as the subscription of the terminal. Based on the mobility level of the terminal, the mobility management control function configures the mobility management sub-functions in the network, and starts the mobility management sub-functions that need to provide services to the terminal, thereby providing the terminal with a customized mobility management mechanism.
現有的按需求移動性支持的解決方案要求網路中實現所有 的移動性管理子功能，增加網路的複雜度，網路中的移動性管理控制功能需要根據移動性支持級別確定啟動哪些移動性管理子功能，增加了網路配置流程，尤其是針對大量要求不同移動性支持的終端，增加移動性管理的複雜度。 Existing on-demand mobility support solutions require all The mobility management sub-functions increase the complexity of the network.

根據本發明的實施方式，提出了一種按需求為終端選擇移動性管理機制的方法及裝置。 According to the embodiments of the present invention, a method and device for selecting a mobility management mechanism for a terminal according to requirements are proposed.
在本發明一些實施方式中，運營商可通過其運營支撐系統獲取的使用者資訊，終端資訊，業務網路或者協力廠商應用提供的業務資訊，使用者的通信模型等，挖掘出其網路中的使用者終端的移動性模型(或規律)，移動應用的特徵。然後基於獲取的上述資訊，可以確定其網路中需要提供的移動性支持等級，例如高、中或低等級的移動性支持。 In some embodiments of the present invention, an operator can mine user information, terminal information, business network or service information provided by third-party application, user communication model, etc., through its operation support system, to dig out its network. Mobility model (or regularity) of user terminals, characteristics of mobile applications. Then based on the obtained information, the level of mobility support that needs to be provided in its network can be determined, such as high, medium or low level of mobility support.
相應地，運營商的網管系統根據所需的移動性支持等級對其網路進行劃分，例如進行網路切片，使得不同網路實現不同等級的移動性支持。但一個網路中可能實現多個等級的移動性支持。 Correspondingly, the network management system of the operator divides its network according to the required mobility support level, for example, performs network slicing, so that different networks implement different levels of mobility support. However, multiple levels of mobility support may be implemented in a network.
當終端接入該運營商網路時，網路中的移動性支持級別判定功能(也可稱為移動性支持級別判定功能實體)，例如移動性等級確定功能(也可稱為移動性等級確定功能實體)，首先根據終端的接入請求，例如附著請求，位置更新請求，連接建立請求等，確定該終端所需的移動性支持級別。根據確定的終端所需的移動性支持級別，網路選擇功能(也可稱為網路選擇功能實體)為終端選擇能夠提供所需移動性支持的網路。 When a terminal accesses the operator's network, the mobility support level determination function (also referred to as a mobility support level determination function entity) in the network, such as a mobility level determination function (also referred to as a mobility level determination A functional entity), first determine a mobility support level required by the terminal according to an access request of the terminal, such as an attach request, a location update request, a connection establishment request, and the like. According to the determined mobility support level required by the terminal, the network selection function (also referred to as a network selection function entity) selects a network that can provide the required mobility support for the terminal.

The execution subject of the method may be a mobility support level determination function (also referred to as a mobility level determination function), which specifically includes the following: step.
步驟S110、確定終端所需的移動性支持級別；3GPP TR 23.799中提出了按需求移動性支持概念的定義，即網路基於終端和業務的不同特性提供不同的移動性支持，上述移動性支持的具體功能可以包括以下任意一項或多項：移動性上下文管理、位置跟蹤(位置更新)、尋呼、切換控制、路徑優化(錨點重選)、可達性管理，當然也並不限於此。 Step S110: Determine the level of mobility support required by the terminal; 3GPP TR 23.799 proposed the definition of the concept of on-demand mobility support, that is, the network provides different mobility support based on different characteristics of terminals and services.

具體地，運營商需獲取的使用者資訊，終端資訊，業務網路或者協力廠商應用提供的業務資訊，使用者的通信模型等，挖掘出其網路中的使用者終端的移動性模型(或規律)，移動應用的特徵。基於獲取的資訊，確定其網路中需要提供的移動性支持等級，例如高，中，低等級的移動性支持，並保存在終端使用者的簽約屬性中。如圖2所示，運營商部署移動描述系統進行終端移動模型的發現和移動業務的描述，從而確定網路中需要提供移動性支持。 Specifically, the operator needs to obtain user information, terminal information, business network or service information provided by third-party application, user communication model, etc., to mine the user terminal mobility model (or Law), characteristics of mobile applications. Based on the obtained information, determine the level of mobility support that needs to be provided in its network, such as high, medium, and low-level mobility support, and save it in the contract attribute of the end user. As shown in Figure 2, the operator deploys a mobile description system to discover the mobile model of the terminal and describe the mobile service, so as to determine the need to provide mobility support in the network.
基於移動描述系統的決策，運營商網路的運營管理層可判斷如何提供所需的移動性支持。若運營管理層的網路切片管理器判斷需要創建新的網路切片，則網路切片管理器需請求網路切片描述系統進行待建立網路切片的描述。網路切片描述系統用於定義待建立網路的所有網路功能和相互連接。為了提供能夠滿足移動性支持需求的移動性管理機制，系統可增加了移動性管理功能體描述(MMF description，mobility management functionality description)功能來進行所有移動性管理子功能體的詳細定義， 輔助網路切片描述功能進行網路切片的定義。當網路切片描述功能完成切片描述後，通知網路切片管理器觸發網路切片的生成。具體實施中，運營商或者MMF功能可能定義如下類型的移動性管理機制：1.控制平面移動性管理功能和用戶平面移動性錨點集中部署在核心網，支持會話連續性；2.控制平面移動性管理功能和用戶平面移動性錨點集中部署在核心網，不支持會話連續性；3.控制平面移動性管理功能集中部署在核心網，用戶平面移動性錨點部署在靠近用戶位置，支持會話連續性；4.控制平面移動性管理功能集中部署在核心網，用戶平面移動性錨點部署在靠近用戶位置，不支持會話連續性；5.控制平面移動性管理功能部署在接入網側，用戶平面移動性錨點部署核心網，支持會話連續性；6.控制平面移動性管理功能部署在接入網側，用戶平面移動性錨點部署在靠近用戶位置，支持會話連續性；7.控制平面移動性管理功能部署在接入網側，用戶平面移動性錨點部署在靠近用戶位置，不支持會話連續性。 Based on the decision of the mobile description system, the operational management of the operator network can determine how to provide the required mobility support. If the network slice manager of the operation management layer determines that a new network slice needs to be created, the network slice manager needs to request the network slice description system to describe the network slice to be created. The network slice description system is used to define all network functions and interconnections of the network to be established. In order to provide a mobility management mechanism that can meet the needs of mobility support, the system can add a mobility management functionality description (MMF description, mobility management functionality description) function to carry out detailed definitions of all mobility management sub-functions. The auxiliary network slice description function defines the network slice. When the network slice description function completes the slice description, the network slice manager is notified to trigger the generation of the network slice. In specific implementation, operators or MMF functions may define the following types of mobility management mechanisms: 1. Control plane mobility management functions and user plane mobility anchors are centrally deployed on the core network to support session continuity; 2. Control plane mobility The mobility management functions and user plane mobility anchors are centrally deployed on the core network, which does not support session continuity; 3. The control plane mobility management functions are centrally deployed on the core network, and the user plane mobility anchors are deployed near the user's location to support sessions Continuity; 4. Control plane mobility management functions are deployed centrally in the core network, user plane mobility anchors are deployed close to user locations, and session continuity is not supported; 5. Control plane mobility management functions are deployed on the access network side, The user plane mobility anchor is deployed in the core network to support session continuity; 6. The control plane mobility management function is deployed on the access network side, and the user plane mobility anchor is deployed near the user's location to support session continuity; 7. Control The plane mobility management function is deployed on the access network side, and the user plane mobility anchor is deployed near the user. It does not support session continuity.
具體的移動性管理功能如圖2所示，可能包括：移動性上下文管理Mobility context management(移動性狀態機維護)；位置跟蹤Location tracking(位置更新)；尋呼paging；切換控制Handover control；路徑優化Path optimization(錨點重選)；可達性管理Reachability mangement。 The specific mobility management functions are shown in Figure 2, which may include: Mobility context management (mobility state machine maintenance); location tracking (location update); paging; handover control; path optimization Path optimization (anchor reselection); Reachability mangement.
網路切片管理器請求編排控制層進行網路切片的具體生成， 例如請求MANO(Management and Orchestration，管理編排域)系統生成具體的網路切片。網路切片生成後，網路切片管理器還負責對其生命週期進行管理，例如修改或撤銷該網路切片。 The network slice manager requests the orchestration control layer to generate specific network slices. For example, request the MANO (Management and Orchestration, management orchestration) system to generate specific network slices. After a network slice is generated, the network slice manager is also responsible for managing its life cycle, such as modifying or revoking the network slice.
該網路切片框架使得網路能夠生成支持不同移動性級別的網路切片，使得不同移動性需求的終端可能被不同的網路切片所服務，例如：當收到靜態的智慧電錶設備的小資料傳輸請求時，為終端選擇控制平面移動性管理功能和用戶平面移動性錨點集中部署在核心網的，不支持會話連續性的網路，無需支持位置跟蹤；當收到SMART phone(智慧型電話)發起的IMS呼叫業務時，為終端選擇控制平面移動性管理功能和用戶平面移動性錨點集中部署在核心網的，支持會話連續性的網路，無需支持路徑優化(錨點不變)。 The network slicing framework enables the network to generate network slices that support different mobility levels, so that terminals with different mobility requirements may be served by different network slices, such as when receiving small data from static smart meter devices When transmitting a request, select the control plane mobility management function and user plane mobility anchor for the terminal to be centrally deployed on the core network. The network does not support session continuity and does not need to support location tracking. When receiving a SMART phone (smart phone) When initiating an IMS call service, a terminal selects a control plane mobility management function and a user plane mobility anchor that are centrally deployed in the core network, and supports a network of session continuity without supporting path optimization (the anchor point remains unchanged).
在一些實施例中，如圖3A和3B所示，每個網路中都實現了移動性級別判定功能，具體實現時，移動性級別判定功能位於對應的網路內，參見圖3A；移動性級別判定功能可能被多網路共用，參見圖3B。目的是為了在終端接入該網路後，根據終端的移動資訊和業務，確定當前終端所需的移動性支持等級，從而為終端選擇能夠提供合適的移動性管理機制或功能的網路。 In some embodiments, as shown in FIGS. 3A and 3B, a mobility level determination function is implemented in each network. In specific implementation, the mobility level determination function is located in a corresponding network, see FIG. 3A; mobility The level determination function may be shared by multiple networks, see FIG. 3B. The purpose is to determine the mobility support level required by the current terminal according to the mobile information and services of the terminal after the terminal accesses the network, so as to select a network that can provide a suitable mobility management mechanism or function for the terminal.
需要說明的是，本實施例中終端附著到網路過程類似相關技術，網路選擇功能根據終端的類型，簽約等選擇目標網路。 It should be noted that the process of attaching the terminal to the network in this embodiment is similar to the related technology, and the network selection function selects the target network according to the type of the terminal, the contract, and the like.

The specific steps are as follows: Step S401, the UE sends an access request in the attached network, such as location update. request, Connection establishment request, etc .; step S402, after the attached network receives the request from the terminal, the mobility level determination function in the network determines the current level of mobility support required by the terminal, and determines whether the network can provide the terminal with the terminal Provide required mobility support; if possible, provide corresponding mobility management to the terminal; step S403, determine that the attached network cannot provide the required mobility support to the terminal, and this mobility level determination function requests the network The path selection function is that the terminal reselects the target network, and the request message carries at least the mobility support level required by the terminal; or the mobility level determination function performs target network selection according to the required mobility support level, and step S404 is skipped. Go to step S405; step S404, the network selection function reselects the target network according to the received information, and responds; step S405, trigger and execute the handover or location update process to redirect the terminal to the target network.
在一些實施例中，參見圖5，圖中示出了網路選擇功能根據終端所需的移動性支持級別選擇目標網路。如圖5所示，移動性等級判定功能獨立與各網路，在終端接入網路，請求位置更新或建立連接時，由網路選擇功能根據終端當前所需的移動性級別選擇合適的目標網路。當然可以理解的是，移動性等級判定功能可能與網路選擇功能設置成一個功能實體。 In some embodiments, referring to FIG. 5, it is shown that the network selection function selects a target network according to the mobility support level required by the terminal. As shown in Figure 5, the mobility level determination function is independent of each network. When the terminal accesses the network and requests location updates or establishes a connection, the network selection function selects a suitable target according to the mobility level currently required by the terminal. network. Of course, it can be understood that the mobility level determination function may be set as a functional entity with the network selection function.
