Description
本發明關於一種用於一無線通訊系統之方法及其通訊裝置,尤指一種用於一無線通訊系統用來管理特屬細胞選擇之方法及其通訊裝置。The present invention relates to a method for a wireless communication system and a communication device thereof, and more particularly to a method for managing a unique cell selection and a communication device for a wireless communication system.
系統架構演進(System Architecture Evolution,SAE)系統,係由第三代行動通訊聯盟(3GPP)規範,為一種通用移動通信系統(Universal Mobile Telecommunications System,UMTS)中新的核心網路架構,為網際網路通訊協定(Internet Protocol,IP)的大眾市場提供高成本效益的部署和運作。網路演進主要包含滿足一長期演進(long term evolution,LTE)系統之無線介面需求、簡化網路結構、全IP網路(即所有服務皆利用封包交換進行傳輸,無包含電路交換技術),以及支持在不同種類的接取網路間,行動及服務上的連續性,例如在2G/3G,長期演進系統,及非3GPP接取系統之間。System Architecture Evolution (SAE) system, standardized by the 3rd Generation Mobile Communications Alliance (3GPP), is a new core network architecture in the Universal Mobile Telecommunications System (UMTS), which is the Internet. The mass market of the Internet Protocol (IP) provides cost-effective deployment and operation. The network evolution mainly includes satisfying the wireless interface requirements of a long term evolution (LTE) system, simplifying the network structure, and all-IP networks (that is, all services are transmitted by using packet switching, without including circuit switching technology), and Supports continuity between different types of access networks, operations and services, such as between 2G/3G, Long Term Evolution, and non-3GPP access systems.
系統架構演進系統包含有一行動管理實體(Mobility Management Entity,MME),一服務閘道(Serving Gateway),以及一公用資料網路閘道(PDN Gateway)。行動管理實體係為一控制平面單元,用以管理網路服務附加,用戶端認證,及協調演進式無線接取網路之相關無線負載的建立。The system architecture evolution system includes a Mobility Management Entity (MME), a Serving Gateway, and a PDN Gateway. The mobile management system is a control plane unit that manages network service attach, client authentication, and coordination of the establishment of associated wireless bearers for the evolved wireless access network.
系統架構演進系統的功能包含有用戶端於閒置模式時所進行之非接取層(Non-Access-Stratum,NAS)功能,用戶端與演進封包核心網路之間透過一演進式通用移動通信系統(Evolved UMTS,E-UTRAN)所進行之非接取層信令流程,以及用戶端與演進封包核心網路之間透過非3GPP接取網路所傳輸之第三層信令流程。The function of the system architecture evolution system includes a non-access-strata (NAS) function performed by the UE in the idle mode, and an evolved universal mobile communication system is communicated between the UE and the evolved packet core network. The non-access layer signaling procedure performed by Evolved UMTS (E-UTRAN) and the Layer 3 signaling flow transmitted between the UE and the evolved packet core network through the non-3GPP access network.
於非接取層中,特屬細胞(Home Cell)部署定義為將單一個基地台用於一建築或一小細胞群組中,如於一校園中。特屬細胞的存取資格限定於特定申訂用戶。於特屬細胞的部署中,一封閉用戶組(Closed Subscriber Group,CSG)細胞可視為特屬細胞的種類之一,其為公用地移動式網路(Public Land Mobile Network,PLMN)的一部分。當封閉用戶組細胞之細胞識別存於一用戶端之一白名單(whitelist)時,則該用戶端可存取該封閉用戶組細胞。換句話說,白名單提供複數個可供存取之封閉用戶組細胞的細胞識別,讓用戶端被允許駐留於白名單所提供的封閉用戶組細胞的服務範圍內。一般來說,白名單是由公用地移動式網路所決定的。In the non-access layer, the Home Cell deployment is defined as the use of a single base station in a building or a small cell group, such as in a campus. Eligibility for access to a particular cell is limited to a particular subscription user. In the deployment of a unique cell, a Closed Subscriber Group (CSG) cell can be considered as one of the types of a particular cell, which is part of a Public Land Mobile Network (PLMN). When the cell identification of the closed user group cell is stored in a whitelist of a client, the client can access the closed user group cell. In other words, the whitelist provides cell identification for a plurality of closed user group cells that are accessible, allowing the client to be allowed to reside within the service of the closed user group cells provided by the whitelist. In general, the whitelist is determined by the public mobile network.
以目前第三代行動通訊聯盟規範來說,其未清楚制定當白名單具有至少一可存取之CSG細胞,但用戶端僅找到一適當之大型細胞而未找到任何CSG細胞時,用戶端應如何處理此一狀況。因此,用戶端無法選擇一CSG細胞以供存取,造成通訊品質的降低。In the current third-generation mobile communication alliance specification, it is not clear that when the whitelist has at least one accessible CSG cell, but the user only finds a suitable large cell and does not find any CSG cells, the user should How to deal with this situation. Therefore, the UE cannot select a CSG cell for access, resulting in a decrease in communication quality.
此外,在服務提供方面,一CSG細胞之服務存取費用低於一大型細胞之服務存取費用,因此使用者於細胞選擇時,會設定用戶端優先選擇一CSG細胞。為節省使用者之服務存取費用,在一細胞選擇程序中,CSG細胞相較其它細胞,如大型細胞,應具有較高的優先選擇順序。In addition, in terms of service provision, the service access fee of a CSG cell is lower than the service access fee of a large cell. Therefore, when the user selects a cell, the user is preferentially selected to select a CSG cell. In order to save the user's service access costs, in a cell selection procedure, CSG cells should have a higher priority order than other cells, such as large cells.
在一手動CSG細胞選擇功能中,用戶端可提供使用者一手動功能,用來啟動CSG細胞搜尋並選擇一CSG細胞。由於網路端希望用戶端可依照一細胞選擇或細胞重選的結果來選擇細胞,因此網路端可能停止此手動功能。然而,目前的規範並未提供一有效控制手動CSG細胞選擇功能啟動的方式。In a manual CSG cell selection function, the user can provide a manual function for the user to initiate CSG cell search and select a CSG cell. Since the network side wants the UE to select cells according to the result of one cell selection or cell reselection, the network may stop this manual function. However, current specifications do not provide a means to effectively control the initiation of manual CSG cell selection.
另一方面,一使用者可能不正常地啟動手動CSG細胞選擇功能。舉例來說,在一手動CSG細胞選擇中,使用者選擇一不准許存取之CSG細胞(如其他使用者之一專屬基地台)。當用戶端企圖存取不被充許之CSG細胞時,相關規範提供一服務請求拒絕程序,其具有一特定拒絕原因值。然而,服務請求拒絕程序涉及用戶端及行動管理實體。基地台必需與行動管理實體建立連結,且行動管理實體需檢查用戶端是否有效存取該CSG細胞。此一方式浪費無線資源與網路端資源在處理用戶端是否錯誤存取的程序上,因而降低用戶端存取CSG細胞的效能。On the other hand, a user may not normally activate the manual CSG cell selection function. For example, in a manual CSG cell selection, the user selects a CSG cell that is not permitted to access (e.g., one of the other users' proprietary base stations). When the client attempts to access an unlicensed CSG cell, the specification provides a service request rejection procedure with a specific rejection reason value. However, the service request rejection procedure involves the client and the action management entity. The base station must establish a connection with the action management entity, and the action management entity needs to check whether the client side has effective access to the CSG cell. This method wastes the wireless resources and the network end resources in the process of processing whether the user terminal accesses incorrectly, thereby reducing the performance of the client accessing the CSG cells.

In this case, embodiments of the present invention provide a unique cell selection process to allow the user to select a particular cell or a large cell. Please refer to FIG. 3, which is a schematic diagram of a specific cell selection process 30 according to an embodiment of the present invention. The unique cell selection process 30 is for storing a whitelist in a client for managing CSG cell selection and compiling to program code 214. The unique cell selection process 30 includes the following steps:
步驟300:開始。Step 300: Start.
步驟302:當該白名單不為空白時,讀取一旗標,以進行細胞選擇,其中該旗標存有一關於特屬細胞或大型細胞兩者至少其一的優先資料。Step 302: When the white list is not blank, a flag is read for cell selection, wherein the flag stores a priority information about at least one of a particular cell or a large cell.
步驟304:根據該旗標,選擇一特屬細胞或一大型細胞。Step 304: Select a specific cell or a large cell according to the flag.
步驟306:結束。Step 306: End.
根據特屬細胞選擇流程30,當白名單包含至少一CSG細胞時,用戶端讀取一旗標,並根據該旗標選擇一CSG細胞或大型細胞。根據編譯之程式碼214,該旗標為旗標F1,其可儲存於一用戶識別模組(Subscriber Identity Module,SIM)或儲存資料212中,而該白名單為白名單216。According to the unique cell selection process 30, when the white list contains at least one CSG cell, the client reads a flag and selects a CSG cell or a large cell based on the flag. According to the compiled code 214, the flag is a flag F1, which can be stored in a Subscriber Identity Module (SIM) or a stored data 212, and the whitelist is a whitelist 216.
值得注意的是,上述實施例之優先資料包含有關於特屬細胞、大型細胞或結合特屬與大型細胞兩者之資料,舉例來說,旗標可設定為「僅有CSG細胞」、「CSG細胞優先」、「大型細胞優先」,以及「無優先」的其中之一。當旗標設為「僅有CSG細胞」,用戶端僅可選擇一CSG細胞駐留。當旗標設為「CSG細胞優先」,在選擇細胞時,用戶端首先於白名單中搜尋一CSG細胞駐留。若用戶端無法在白名單中找到任何CSG細胞,但找到一大型細胞時,則用戶端選擇該大型細胞駐留。當旗標設為「大型細胞優先」,在選擇細胞時,用戶端優先搜尋一大型細胞駐留。若用戶端無法在白名單中找到任何大型細胞,但於該白名單中找到一CSG細胞,則用戶端選擇該CSG細胞駐留。當旗標設為「無優先」,在選擇細胞時,用戶端可於白名單中選擇任一CSG細胞或一大型細胞駐留。It is worth noting that the priority information of the above embodiments includes information about a particular cell, a large cell, or a combination of a specific gene and a large cell. For example, the flag can be set to "CSG only" and "CSG". One of the "cell priority", "large cell priority", and "no priority". When the flag is set to "CSG only", the client can only select one CSG cell to reside. When the flag is set to "CSG cell priority", when selecting a cell, the client first searches for a CSG cell resident in the white list. If the client cannot find any CSG cells in the whitelist, but finds a large cell, the client selects the large cell to reside. When the flag is set to "large cell priority", when selecting cells, the client preferentially searches for a large cell resident. If the client cannot find any large cells in the whitelist but finds a CSG cell in the whitelist, the client selects the CSG cell to reside. When the flag is set to "no priority", when selecting cells, the client can select any CSG cell or a large cell to reside in the whitelist.
較佳地,旗標可透過一使用者更新,或根據一專用信令訊息更新,該專用信令訊息係由該用戶端所駐之網路端所傳送,此外,專用信令訊息可為一短訊息服務(short message service)訊息。Preferably, the flag can be updated by a user or updated according to a dedicated signaling message transmitted by the network station where the client is located.

除此之外,本發明實施例可提供用戶端一手動CSG細胞選擇功能,讓使用者可以手動方式控制用戶端啟動CSG細胞搜尋,並於搜尋到之CSG細胞中,選擇任一CSG細胞。在此情況下,旗標F2用來控制手動CSG細胞選擇功能。In addition, the embodiment of the present invention can provide a manual CSG cell selection function at the user end, so that the user can manually control the user to initiate CSG cell search, and select any CSG cell in the searched CSG cells. In this case, the flag F2 is used to control the manual CSG cell selection function.
本發明實施例提供一細胞選擇管理流程,以避免因不當地啟動手動CSG細胞選擇功能,而造成系統錯誤。請參考第4圖,第4圖為本發明實施例一細胞選擇管理流程40之示意圖。細胞選擇管理流程40用於存有一白名單之一用戶端中,用來管理CSG細胞選擇,並可編譯為程式碼214。細胞選擇管理流程40包含有以下步驟:Embodiments of the present invention provide a cell selection management process to avoid system errors caused by improperly initiating manual CSG cell selection functions. Please refer to FIG. 4, which is a schematic diagram of a cell selection management process 40 according to an embodiment of the present invention. The cell selection management process 40 is used to store a whitelist in a client for managing CSG cell selection and can be compiled into code 214. The cell selection management process 40 includes the following steps:
步驟400:開始。Step 400: Start.

較佳地,該旗標為通訊裝置20之旗標F2,並儲存於用戶識別模組或儲存資料212中。此外,旗標可根據一專用信令訊息更新,該專用信令訊息係由該用戶端所駐之網路端所傳送,此外專用信令訊息可為一短訊息服務(short message service)訊息。Preferably, the flag is the flag F2 of the communication device 20 and is stored in the user identification module or the stored data 212. In addition, the flag may be updated according to a dedicated signaling message transmitted by the network station where the client is located, and the dedicated signaling message may be a short message service message.
透過細胞選擇管理流程40,網路端可透過更新旗標的設定,控制用戶端啟動或關閉手動CSG細胞選擇功能。Through the cell selection management process 40, the network can control the user to enable or disable the manual CSG cell selection function by updating the flag setting.
當手動CSG細胞選擇功能啟動時,用戶端可搜尋到白名單之外的CSG細胞。在此情況下,本發明實施例提供一細胞選擇管理流程,以幫助網路端管理用戶端之手動CSG細胞選擇功能。請參考第5圖,第5圖為本發明實施例一細胞選擇管理流程50之示意圖。細胞選擇管理流程50用於存有一白名單之一用戶端中,用以管理CSG細胞選擇,以及可編譯為程式碼214。細胞選擇管理流程50包含有以下步驟:When the manual CSG cell selection function is activated, the client can search for CSG cells outside the whitelist. In this case, the embodiment of the present invention provides a cell selection management process to help the network side manage the manual CSG cell selection function of the user end. Please refer to FIG. 5. FIG. 5 is a schematic diagram of a cell selection management process 50 according to an embodiment of the present invention. The cell selection management process 50 is used to store a whitelist in a client to manage CSG cell selection and to compile into code 214. The cell selection management process 50 includes the following steps:
步驟500:開始。Step 500: Start.
步驟502:當選擇一不屬於該白名單之CSG細胞時,終止手動CSG細胞選擇功能。Step 502: When a CSG cell that does not belong to the white list is selected, the manual CSG cell selection function is terminated.
步驟504:結束。Step 504: End.
根據細胞選擇管理流程50,當用戶端選擇不屬於該白名單之一CSG細胞時,則終止手動CSG細胞選擇功能。換句話說,選擇不屬於該白名單之任一CSG細胞的操作將觸發用戶端終止手動CSG細胞選擇功能。According to the cell selection management process 50, when the client selects a CSG cell that does not belong to the white list, the manual CSG cell selection function is terminated. In other words, selecting an operation that does not belong to any of the CSG cells of the white list will trigger the client to terminate the manual CSG cell selection function.
在習知技術中,一CSG細胞之服務基地台為網路端的一部分,其與一行動管理實體(Mobility Management Entity,MME)進行一特定程序,以終止CSG細胞選擇。透過細胞選擇管理流程50,本發明實施例清楚說明當選擇的CSG細胞不屬於白名單時,用戶端可主動終止手動CSG細胞選擇功能,因而可避免CSG細胞之服務基地台與行動管理實體間處理用戶端是否錯誤存取的程序,以及避免CSG細胞選擇功能異常的啟動。In the prior art, a serving base station of a CSG cell is a part of the network side, and performs a specific procedure with a Mobility Management Entity (MME) to terminate CSG cell selection.
