Description
本發明相關於一種對行動裝置進行網路個人化之方法，尤指一種可準確區別合作電信業者之對行動裝置進行網路個人化之方法。 The present invention relates to a method for personalizing a mobile device, and more particularly to a method for accurately distinguishing a mobile device from a cooperative carrier.
用戶識別模組(Subscriber Identity Module,SIM)卡是一種用來保存行動電話服務的用戶身份識別數據的智慧卡，同時可用來儲存簡訊資料和電話號碼。在外部硬體方面，SIM卡由中央處理器(central process unit,CPU)、唯讀記憶體(read-only memory,ROM)、隨機存取記憶體(random access memory,RAM)、電子式可抹除程式化唯讀記憶體(electrically erasable programmable read-only memory,EEPROM)和輸入/輸出(I/O)電路等元件所組成。在內部資料方面，SIM卡採用分級(hierarchical)的邏輯資料結構，其包含基本文件(elementary file,EF)、專有文件(dedicated file,DF)和主要文件(master file,MF)等3種類型的資料。 A Subscriber Identity Module (SIM) card is a smart card used to store user identification data for mobile phone services. It can also be used to store SMS messages and phone numbers. In terms of external hardware, the SIM card is composed of a central processing unit (CPU), a read-only memory (ROM), a random access memory (RAM), and an electronically smeared It consists of components such as electrically erasable programmable read-only memory (EEPROM) and input/output (I/O) circuits. In terms of internal data, the SIM card adopts a hierarchical logical data structure, which includes three types: elementary file (EF), dedicated file (DF), and master file (MF). data of.
依據第三代合作計劃(3rd Generation Partnership Project,3GPP)所制定之規範TS 22.022，行動裝置(mobile equipment,ME)包含5種類型的個人化：網路個人化(network personalization)、網路 子集合個人化(network subset personalization)、服務提供商個人化(service provider personalization)、企業個人化(corporate personalization)、用戶識別模組/通用用戶識別模組個人化(SIM/USIM personalization)。在用戶將SIM卡***行動裝置後，在開機過程中一方面可對用戶身份進行識別，另一方面可識別營運商網絡或內存電話號碼等其他信息。用戶實際上是利用行動裝置向SIM卡發出命令，SIM卡應該根據標準規範和其設定來執行或拒絕。 According to the specification TS 22.022 of the 3rd Generation Partnership Project (3GPP), mobile equipment (ME) contains five types of personalization: network personalization, network Network subset personalization, service provider personalization, corporate personalization, user identification module/SIM/USIM personalization. After the user inserts the SIM card into the mobile device, the user identity can be identified on the one hand during the boot process, and other information such as the operator network or the memory phone number can be identified on the other hand. The user actually uses the mobile device to issue commands to the SIM card, which should be executed or rejected according to standard specifications and their settings.
在先前技術之網路個人化方法中，行動裝置會取得特定網路之行動國家碼(mobile country code,MCC)和行動網路碼(mobile network code,MNC)來作為比對資料。每次開機後，行動裝置會讀取目前安裝SIM/USIM卡內國際行動用戶辨識基本文件(International mobile Subscriber Identity elementary file,EF_IMSI)之內容以取得內嵌之MCC和MNC，再判斷MCC和MNC是否符合內存之比對資料，唯有在資料相符時行動裝置才能在正常模式下運作。換而言之，當特定行動裝置經過網路個人化後，只能在安裝特定電信業者發行的SIM卡時才能運作。若不慎遺失此行動裝置，他人將無法換上其它電信業者發行的SIM卡來使用。 In the prior art network personalization method, the mobile device obtains a mobile country code (MCC) and a mobile network code (MNC) of a specific network as comparison data. After each boot, the mobile device reads the contents of the currently installed SIM/USIM card (International Mobile Subscriber Identity Elementary File, EF_IMSI) to obtain the embedded MCC and MNC, and then judges whether the MCC and the MNC are In line with the memory comparison data, the mobile device can only operate in the normal mode when the data matches. In other words, when a particular mobile device is personalized via the Internet, it can only be operated when a SIM card issued by a particular carrier is installed. If this mobile device is accidentally lost, others will not be able to use the SIM card issued by other carriers to use it.
第1圖為依據3GPP規範TS 51.011所定義之SIM卡基本文件EF_IMSI的示意圖。如欄位10所示，位元組2至9係用來儲存IMSI資料。依據3GPP規範TS 23.003，IMSI資料內嵌MCC和MNC，由三位數代碼所組成MCC可唯一地辨識電信業者的國別，而由二位數或三位數代碼所組成MNC可唯一地辨識電信業者的公共陸地移動網路(Public Land Mobile Network,PLMN)。 Figure 1 is a schematic diagram of a SIM card base file EF_IMSI as defined by the 3GPP specification TS 51.011. As shown in field 10, bytes 2 through 9 are used to store IMSI data. According to the 3GPP specification TS 23.003, the IMSI data embeds the MCC and the MNC. The MCC consisting of three-digit codes can uniquely identify the country of the carrier, and the MNC composed of two-digit or three-digit codes can uniquely identify the telecommunications. The public land mobile network (PLMN) of the industry.
如果電信業者A和電信業者B為合作業者，兩者發行的SIM卡內國際行動用戶辨識基本文件EF_IMSI會具備相同MCC和MNC。因此，針對電信業者A和電信業者B所分別發行之不同SIM卡，先前技術之網路個人化方法並無法區別兩者在特定行動裝置上之使用權限。 If Carrier A and Carrier B are cooperators, the International Mobile Subscriber Identification Base File EF_IMSI in the SIM card issued by both will have the same MCC and MNC. Therefore, for different SIM cards issued by Carrier A and Carrier B, the prior art network personalization method cannot distinguish the usage rights of the two on a specific mobile device.

第3圖為依據3GPP規範TS 51.011所定義之SIM卡服務提供者名稱基本文件EF_SPN的示意圖。欄位20定義了讀取(READ)、更新(UPDATE)、廢止(INVALIDATE)和回復(REHABILATATE)基本文件EF_SPN的條件，其中ALWAYS代表隨時可讀取基本文件EF_SPN。欄位30說明了基本文件EF_SPN可用2~17個位元來描述服務提供者名稱。在步驟210中，本發明可讀取特定智慧卡內國際行動用戶辨識基本文件EF_IMSI之內嵌內容和服務提供者名稱基本文件EF_SPN之內容，以取得特定智慧卡內 EF_IMSI之MCC、MNC和服務提供者名稱。 Figure 3 is a schematic diagram of the SIM card service provider name base file EF_SPN as defined by the 3GPP specification TS 51.011. Field 20 defines the conditions for the read (READ), update (UPDATE), revoke (INVALIDATE), and reply (REHABILATATE) base files EF_SPN, where ALWAYS stands for the base file EF_SPN to be read at any time. Field 30 indicates that the base file EF_SPN can use 2 to 17 bits to describe the service provider name. In step 210, the present invention can read the content of the embedded content of the international mobile user identification basic file EF_IMSI and the service provider name basic file EF_SPN in the specific smart card to obtain the specific smart card. MC_IMSI's MCC, MNC and service provider name.
在步驟220中，本發明會判斷是否通過預個人化確認。依據3GPP規範TS 22.022，在每種類型的個人化週期內，在變更任何資料前皆需進行預個人化確認，以確保下列兩條件成立： In step 220, the present invention determines whether or not to pass the pre-personalization confirmation. According to the 3GPP specification TS 22.022, pre-personalization confirmation is required before each data is changed during each type of personalization cycle to ensure that the following two conditions are met:
條件1：欲進行之特定類型的個人化尚未被啟動。 Condition 1: The specific type of personalization to be performed has not yet been initiated.
條件2：欲儲存之相關於特定類型的個人化比對資料需為現有個人化碼的子集合。 Condition 2: The personalization comparison data to be stored in relation to a particular type needs to be a subset of the existing personalization code.
舉例來說，若先前已經完成網路個人化，現在欲修改網路個人化之內容，此時需先針對網路個人化執行解個人化(de-personalization)，條件1才會成立。若現有個人化碼已包含先前針對SIM/USIM個人化之比對資料SU1，而步驟210中取得相關於網路個人化之比對資料N1，此時現有個人化碼需以(SU1-N1)之方式更新，條件2才會成立。若現有個人化碼以(SU2-N1)之方式更新，條件2不會成立。若條件1和條件2其中之一不成立，本發明會執行步驟290以結束網路個人化。 For example, if the Internet personalization has been completed before, and now you want to modify the content of the network personalization, you must first perform de-personalization for the network personalization, condition 1 will be established. If the existing personalization code already contains the comparison data SU1 previously for SIM/USIM personalization, and in step 210, the comparison data N1 related to the network personalization is obtained, and the existing personalization code needs to be (SU1-N1). The way to update, condition 2 will be established. If the existing personalization code is updated in the manner of (SU2-N1), condition 2 will not hold. If one of Condition 1 and Condition 2 does not hold, the present invention performs step 290 to end the network personalization.
若通過預個人化確認，本發明在步驟230中會將步驟210中取得之MCC、MNC和SPN存入行動裝置以做為比對資料，並設定相關網路個人化之參數。依據3GPP規範TS 22.022，設定相關網路個人化之參數包含存入一網路個人化控制鍵(network control key)NCK和設定一網路個人化指標(network personalization indicator)之狀態。網路個人化控制鍵NCK可為8~16位元之十進位串，通常由營運商隨機分配，在將網路個人化控制鍵NCK存入行動裝置後，之後欲執行網路解個人化時需先輸入正確的網路個人化 控制鍵NCK。網路個人化指標則用來指示網路個人化是在啟動(ON)/關閉(OFF)狀態，本發明在步驟230中會將網路個人化指標設成”ON”狀態，代表已啟動網路個人化。因此，行動裝置在開機時需執行相對應之確認步驟，之後會加以說明。 If the pre-personalization is confirmed, the present invention stores the MCC, MNC and SPN obtained in step 210 into the mobile device as the comparison data in step 230, and sets the parameters of the relevant network personalization. According to the 3GPP specification TS 22.022, the parameters for setting the relevant network personalization include the state of depositing a network control key NCK and setting a network personalization indicator. The network personalization control key NCK can be a decimal string of 8 to 16 bits, which is usually randomly assigned by the operator. After the network personalized control key NCK is stored in the mobile device, and then the network is depersonalized. Need to enter the correct network personalization first Control key NCK. The network personalization indicator is used to indicate that the network personalization is in an ON/OFF state, and the present invention sets the network personalization indicator to an "ON" state in step 230, which represents the activated network. Road personalization. Therefore, the mobile device needs to perform the corresponding confirmation step at the time of power-on, which will be explained later.
當行動裝置在步驟240中重新開機後，接著會在步驟250中讀取目前安裝智慧卡內國際行動用戶辨識基本文件EF_IMSI和服務提供者名稱基本文件EF_SPN之內容，並在步驟260判斷從目前安裝智慧卡所讀取之EF_IMSI中內嵌之MCC/MNC和EF_SPN是否符合步驟230中存入之比對資料。若資料符合，代表目前安裝中的現有智慧卡和先前執行網路個人化時所用的智慧卡皆為同一服務提供商所發行，此時會執行步驟270以進入正常模式，用戶可透過行動裝置使用所有已申請之功能。若資料不符合，代表目前安裝中的現有智慧卡和先前執行網路個人化時所用的智慧卡並非同一服務提供商所發行，此時會執行步驟280以進入受限模式。受限模式可為3GPP規範TS 22.022中定義之「僅限緊急通話模式」(emergency calls only mode)，行動裝置會使用訪客位置註冊(visitor location register,VLR)分配之臨時行動用戶識別碼(temporary mobile subscriber identity,TMSI)來送出緊急通話的要求。 After the mobile device is rebooted in step 240, the contents of the currently installed smart card international mobile subscriber identification basic file EF_IMSI and the service provider name basic file EF_SPN are read in step 250, and it is determined in step 260 that the current installation is performed. Whether the MCC/MNC and EF_SPN embedded in the EF_IMSI read by the smart card meet the comparison data stored in step 230. If the data is consistent, the existing smart card currently installed and the smart card used in the previous network personalization are all issued by the same service provider. At this time, step 270 is executed to enter the normal mode, and the user can use the mobile device. All the features that have been requested. If the data does not match, the existing smart card currently installed and the smart card used in the previous execution of the network personalization are not issued by the same service provider. At this time, step 280 is executed to enter the restricted mode. The restricted mode can be the "emergency calls only mode" defined in the 3GPP specification TS 22.022, and the mobile device uses the temporary location user register (VLR) assigned temporary mobile subscriber identity (temporary mobile Subscriber identity, TMSI) to send out emergency calls.
本發明使用特定智慧卡內國際行動用戶辨識基本文件EF_IMSI之MCC、MNC和服務提供者名稱基本文件EF_SPN之SPN來做為網路個人化之比對資料，其中SPN可用來區分不同電信業者。在本發明中，針對電信業者A和電信業者B所分別發行之不同SIM卡，即使電信業者A和電信業者B因為是為合作業者使其發行之SIM卡內EF_IMSI具備相同MCC和MNC，本發明之網路個人化方 法亦能準確地區別兩者在特定行動裝置上之使用權限。 The invention uses the SPN of the MCC, the MNC and the service provider name basic file EF_SPN of the international mobile user identification basic file EF_IMSI in the specific smart card as the comparison data of the network personalization, wherein the SPN can be used to distinguish different telecommunication operators. In the present invention, for the different SIM cards issued by the carrier A and the carrier B respectively, even if the carrier A and the carrier B have the same MCC and MNC in the SIM card issued by the partner for the cooperation, the present invention Internet personalization The law also accurately distinguishes the usage rights of the two on a particular mobile device.
以上所述僅為本發明之較佳實施例，凡依本發明申請專利範圍所做之均等變化與修飾，皆應屬本發明之涵蓋範圍。 The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
