这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings.

在对本公开实施例进行详细的解释说明之前，先对本公开实施例的应用场景予以介绍。由于相关技术中，在使用第一SIM卡进行通信的过程中，终端根据连接第一SIM卡对应的移动网络的连接情况，存储有当前时间之前的TAC禁止列表，该TAC禁止列表包括多个小区的TAC，终端在该多个小区内无法连接到移动网络。当终端由第一SIM卡切换到第二SIM卡时，上述TAC禁止列表仍旧存在，若当前所处的小区属于该TAC禁止列表中的小区，将导致该终端无法通过第二SIM卡接入到移动网络。因此，本公开实施例提供了一种网络切换方法，当检测到由第一SIM卡切换到第二SIM卡时，将TAC禁止列表清空，并根据该第二SIM卡的身份信息，将当前所连接的移动网络切换至第二SIM卡对应的移动网络，实现网络切换。由于在将所连接的移动网络切换至第二SIM卡对应的移动网络之前，终端将存储的TAC禁止列表清空，因此，在通过第二SIM卡连接移动网络时，不会因为网络切换之前存储的TAC禁止列表，而影响终端当前通过第二SIM卡连接移动网络，也即，避免出现当前所处的小区属于该TAC禁止列表中的小区时，导致该终端无法通过第二SIM卡接入到移动网络的情况。Before explaining and describing the embodiments of the present disclosure in detail, the application scenarios of the embodiments of the present disclosure will be introduced first. In the related art, in the process of using the first SIM card for communication, the terminal stores the TAC prohibition list before the current time according to the connection status of the mobile network corresponding to the first SIM card, and the TAC prohibition list includes multiple cells TAC, the terminal cannot connect to the mobile network in the multiple cells. When the terminal is switched from the first SIM card to the second SIM card, the above-mentioned TAC prohibition list still exists. If the cell currently located belongs to the cell in the TAC prohibition list, the terminal cannot access the SIM card through the second SIM card. mobile network. Therefore, an embodiment of the present disclosure provides a network switching method. When switching from the first SIM card to the second SIM card is detected, the TAC forbidden list is cleared, and the current The connected mobile network is switched to the mobile network corresponding to the second SIM card to realize network switching. Since the terminal clears the stored TAC prohibition list before switching the connected mobile network to the mobile network corresponding to the second SIM card, when connecting to the mobile network through the second SIM card, it will not The TAC prohibition list affects the current connection of the terminal to the mobile network through the second SIM card, that is, to avoid the fact that the terminal cannot access the mobile network through the second SIM card when the cell currently located belongs to the cell in the TAC prohibition list. network situation.
图1是本公开实施例提供的一种网络切换方法流程图，该网络切换方法用于双卡单通的终端中，该终端上安装有第一SIM卡和第二SIM卡，如图1所示，该网络切换方法包括以下步骤。Fig. 1 is a flow chart of a network switching method provided by an embodiment of the present disclosure.

在步骤101中，当检测到由第一SIM卡切换到第二SIM卡时，将存储的TAC禁止列表清空，该TAC禁止列表用于存储禁止进行网络连接的小区TAC。In step 101, when switching from the first SIM card to the second SIM card is detected, the stored TAC prohibition list is cleared, and the TAC prohibition list is used to store TACs of cells prohibited from network connection.

本公开实施例中，由于在将所连接的移动网络切换至第二SIM卡对应的移动网络之前，终端将存储的TAC禁止列表清空，因此，在当前所连接的移动网络切换至第二SIM卡连接移动网络时，不会因为网络切换之前存储的TAC禁止列表，而影响终端当前通过第二SIM卡连接移动网络，也即，避免出现当前所处的小区属于该TAC禁止列表中的小区时，导致该终端无法通过第二SIM卡接入到移动网络的情况。In the embodiment of the present disclosure, since the terminal clears the stored TAC prohibition list before switching the connected mobile network to the mobile network corresponding to the second SIM card, the currently connected mobile network is switched to the second SIM card When connecting to the mobile network, the TAC prohibition list stored before the network switch will not affect the current connection of the terminal to the mobile network through the second SIM card, that is, to avoid the current cell belonging to the cell in the TAC prohibition list, As a result, the terminal cannot access the mobile network through the second SIM card.

上述所有可选技术方案，均可按照任意结合形成本公开的可选实施例，本公开实施例对此不再一一赘述。All the above optional technical solutions may be combined in any way to form optional embodiments of the present disclosure, which will not be described in detail in the embodiments of the present disclosure.
图2是本公开实施例提供的另一种网络切换方法流程图，该网络切换方法应用于双卡单通的终端中，该终端上安装有第一SIM卡和第二SIM卡，如图2所示，该网络切换方法包括以下步骤。Fig. 2 is a flowchart of another network switching method provided by an embodiment of the present disclosure. The network switching method is applied to a dual-card single-pass terminal, and the terminal is installed with a first SIM card and a second SIM card, as shown in Fig. 2 As shown, the network switching method includes the following steps.
在步骤201中，当检测到由第一SIM卡切换到第二SIM卡时，将存储的TAC禁止列表清空，该TAC禁止列表用于存储禁止进行网络连接的小区TAC。In step 201, when switching from the first SIM card to the second SIM card is detected, the stored TAC prohibition list is cleared, and the TAC prohibition list is used to store TACs of cells prohibited from network connection.
在本公开实施例中，终端上安装有两个SIM卡，为了便于说明，将终端当前正在使用的SIM卡作为第一SIM卡，将网络切换后使用的SIM卡作为第二SIM卡。另外，终端在使用第一SIM卡与其他终端进行信息交互的过程中，终端是通过当前所处的小区与其他终端实现信息交互，而每个小区都有自己对应的TAC。如果终端在当前所处的小区内出现网络连接失败，终端可以将该小区的TAC存储于TAC禁止列表中，避免终端在同一小区重复尝试进行网络连接。也即，在终端在使用第一SIM卡的过程中，终端根据连接第一SIM卡对应的移动网络的连接情况，存储有当前时间之前的TAC禁止列表。其中，该移动网络可以为LTE网络，LTE网络为现有的3G网络的演进网络，LTE网络因其高效的信息交互速度而被广泛使用。In the embodiment of the present disclosure, two SIM cards are installed on the terminal. For ease of description, the SIM card currently used by the terminal is used as the first SIM card, and the SIM card used after network switching is used as the second SIM card. In addition, when the terminal uses the first SIM card to perform information interaction with other terminals, the terminal implements information interaction with other terminals through the cell it is currently in, and each cell has its own corresponding TAC. If the terminal fails to connect to the network in the current cell, the terminal can store the TAC of the cell in the TAC forbidden list, so as to prevent the terminal from repeatedly trying to connect to the network in the same cell. That is, when the terminal is using the first SIM card, the terminal stores the TAC prohibition list before the current time according to the connection status of the mobile network corresponding to the first SIM card. Wherein, the mobile network may be an LTE network, and the LTE network is an evolution network of the existing 3G network, and the LTE network is widely used because of its efficient information exchange speed.
由于该TAC禁止列表中的小区是终端在使用第一SIM卡的过程中添加的，当终端切换至第二SIM卡时，当终端当前所处的小区属于上述TAC禁止列表中的小区时，该小区对应的MME(Mobility Management Entity，移动管理实体)可能允许该终端接入该小区，但是由于该小区属于TAC禁止列表中的小区，导致终端无法通过第二SIM卡接入该小区。因此，在本公开实施例中，当终端由第一SIM卡切换至第二SIM卡时，为了使终端可以顺利连接至第二SIM卡对应的移动网络，在终端检测到由第一SIM卡切换到第二SIM卡时，终端可以将当前时间之前存储的TAC禁止列表清空。Since the cells in the TAC forbidden list are added by the terminal during the use of the first SIM card, when the terminal switches to the second SIM card, when the cell where the terminal is currently located belongs to the above-mentioned cells in the TAC forbidden list, the The MME (Mobility Management Entity, Mobility Management Entity) corresponding to the cell may allow the terminal to access the cell, but because the cell belongs to the cell in the TAC forbidden list, the terminal cannot access the cell through the second SIM card. Therefore, in the embodiment of the present disclosure, when the terminal is switched from the first SIM card to the second SIM card, in order to enable the terminal to smoothly connect to the mobile network corresponding to the second SIM card, when the terminal detects that the first SIM card is switched When accessing the second SIM card, the terminal can clear the TAC prohibition list stored before the current time.
另外，在本公开实施例中，该网络切换方法应用于双卡单通的终端中，针对双卡单通的终端，目前主要有手动切换和自动切换两种网络切换方式。手动切换，也即只有当终端检测到针对网络切换的指令时，终端才会由第一SIM卡切换至第二SIM卡，例如，在终端中有“网络切换”选项，当用户通过预设操作触发该“网络切换”选项时，终端将检测到针对网络切换的指令，然后由第一SIM卡切换至第二SIM卡。其中，预设操作可以为点击操作、滑动操作等。自动切换，也即在终端中安装有控制模块，该控制模块可以不停地在两个移动网络之间切换，并自动搜索网络，当该控制模块在两个网络之间切换时，终端也可以检测到该网络切换操作。因此，无论终端通过手动切换还是自动切换实现网络切换，终端都可以检测到由第一SIM卡切换到第二SIM卡的操作，然后执行步骤201。In addition, in the embodiments of the present disclosure, the network switching method is applied to a dual-card single-pass terminal. For a dual-card single-pass terminal, there are mainly two network switching methods: manual switching and automatic switching. Manual switching, that is, only when the terminal detects an instruction for network switching, the terminal will switch from the first SIM card to the second SIM card. For example, there is a "network switching" option in the terminal. When the user passes the preset operation When the "network switching" option is triggered, the terminal will detect an instruction for network switching, and then switch from the first SIM card to the second SIM card. Wherein, the preset operation may be a click operation, a slide operation, and the like. Automatic switching, that is, a control module is installed in the terminal, and the control module can continuously switch between two mobile networks and automatically search for the network. When the control module switches between the two networks, the terminal can also This network switch operation was detected. Therefore, regardless of whether the terminal implements network switching through manual switching or automatic switching, the terminal can detect the operation of switching from the first SIM card to the second SIM card, and then perform step 201 .
在步骤202中，确定第二SIM卡的身份信息。In step 202, the identity information of the second SIM card is determined.
当终端将当前时间之前存储的TAC禁止列表清空之后，终端可以将网络由第一SIM卡切换至第二SIM卡，然后接入第二SIM卡对应的移动网络。在终端接入第二SIM卡对应的移动网络的过程中，MME中的鉴权中心需要对该第二SIM卡的身份信息进行验证，以确定是否允许终端接入该第二SIM卡对应的移动网络，因此，终端需要先确定该第二SIM卡的身份信息。After the terminal clears the TAC prohibition list stored before the current time, the terminal can switch the network from the first SIM card to the second SIM card, and then access the mobile network corresponding to the second SIM card. When the terminal accesses the mobile network corresponding to the second SIM card, the authentication center in the MME needs to verify the identity information of the second SIM card to determine whether the terminal is allowed to access the mobile network corresponding to the second SIM card. network, therefore, the terminal needs to first determine the identity information of the second SIM card.
其中，第二SIM卡的身份信息用于唯一标识该第二SIM卡，在第二SIM和MME的鉴权中心中预先存储有该第二SIM卡的身份信息，该第二SIM卡的身份信息包括IMSI(International Mobile Subscriber Identity，国际移动用户识别码)和Ki(Keyidentifier，手机鉴权密钥)等。IMSI用于唯一识别移动用户也即SIM卡，Ki为SIM卡与运营商之间加密数据传递的密钥，且IMSI和Ki配合使用可以用来验证该第二SIM卡的身份信息。Wherein, the identity information of the second SIM card is used to uniquely identify the second SIM card, the identity information of the second SIM card is pre-stored in the authentication center of the second SIM and the MME, and the identity information of the second SIM card Including IMSI (International Mobile Subscriber Identity, International Mobile Subscriber Identity) and Ki (Keyidentifier, mobile phone authentication key), etc. The IMSI is used to uniquely identify the mobile user, that is, the SIM card, and Ki is the key for encrypted data transfer between the SIM card and the operator, and the combination of IMSI and Ki can be used to verify the identity information of the second SIM card.
在步骤203中，根据第二SIM卡的身份信息，将当前所连接的移动网络切换至第二SIM卡对应的移动网络，以实现网络切换。In step 203, according to the identity information of the second SIM card, the currently connected mobile network is switched to the mobile network corresponding to the second SIM card, so as to realize network switching.
在本公开实施例中，终端在确定第二SIM卡的身份信息后，可以将第二SIM卡的身份信息发送给鉴权中心，当鉴权中心接收到该第二SIM卡的身份信息时，对该第二SIM卡的身份信息进行验证，如果验证通过，则允许该终端通过第二SIM卡接入该第二SIM卡对应的移动网络，实现终端由第一SIM卡对应的移动网络切换至第二SIM卡对应的移动网络。In the embodiment of the present disclosure, after determining the identity information of the second SIM card, the terminal may send the identity information of the second SIM card to the authentication center, and when the authentication center receives the identity information of the second SIM card, Verify the identity information of the second SIM card, and if the verification is passed, the terminal is allowed to access the mobile network corresponding to the second SIM card through the second SIM card, so that the terminal is switched from the mobile network corresponding to the first SIM card to the mobile network corresponding to the second SIM card. The mobile network corresponding to the second SIM card.
在一种可能的实现方式中，鉴权中心对该第二SIM卡的身份信息进行验证的实现过程可以为：当鉴权中心接收到该第二SIM卡的身份信息时，通过该第二SIM卡身份信息包括的IMSI和Ki，计算出SRES(Signed Response，签字应答)，如果鉴权中心计算出的SRES和第二SIM卡通过IMSI和Ki计算出的SRES相同，则鉴权成功，表明终端可以接入该第二SIM卡对应的移动网络。否则鉴权不成功，也即终端没有权限接入该第二SIM卡对应的移动网络。In a possible implementation manner, the implementation process for the authentication center to verify the identity information of the second SIM card may be: when the authentication center receives the identity information of the second SIM card, through the second SIM The IMSI and Ki included in the card identity information calculate the SRES (Signed Response, signature response). If the SRES calculated by the authentication center is the same as the SRES calculated by the second SIM card through the IMSI and Ki, the authentication is successful, indicating that the terminal The mobile network corresponding to the second SIM card can be accessed. Otherwise, the authentication is unsuccessful, that is, the terminal has no right to access the mobile network corresponding to the second SIM card.
可选地，在本公开实施例中，在终端通过第二SIM卡接入移动网络之后，也即在终端通过第二SIM卡与其他终端进行信息交互的过程中，终端可以根据接入该第二SIM卡对应的移动网络的情况，对清空后的TAC禁止列表进行更新。终端对清空后的TAC禁止列表进行更新可以通过步骤204来实现。Optionally, in this embodiment of the present disclosure, after the terminal accesses the mobile network through the second SIM card, that is, during the information interaction process between the terminal and other terminals through the second SIM card, the terminal may In the case of the mobile network corresponding to the second SIM card, the cleared TAC prohibition list is updated. The terminal may update the cleared TAC prohibition list through step 204 .
在步骤204中，确定网络连接失败的小区，并将该网络连接失败的小区的TAC添加到清空后的TAC禁止列表中，以更新该TAC禁止列表。In step 204, the cell whose network connection fails is determined, and the TAC of the cell whose network connection fails is added to the cleared TAC forbidden list, so as to update the TAC forbidden list.
在终端接入第二SIM卡对应的移动网络之后，终端当前可能出现连接网络失败情况，此时为了避免终端重复尝试接入该小区，终端可以将网络连接失败的小区的TAC添加到清空后的TAC禁止列表中，使得终端无法通过第二SIM卡接入该网络连接失败小区。After the terminal accesses the mobile network corresponding to the second SIM card, the terminal may fail to connect to the network. At this time, in order to prevent the terminal from repeatedly trying to access the cell, the terminal can add the TAC of the cell that failed to connect to the network to the cleared In the TAC prohibition list, the terminal cannot access the network connection failure cell through the second SIM card.
其中，终端确定网络连接失败的小区可以通过以下两种可能的方式实现。Wherein, the terminal may determine the cell whose network connection fails in the following two possible manners.
第一种可能的方式，当终端当前与该第二SIM卡对应的移动网络出现中断，也即网络连接失败时，确定连接失败次数，当连接失败次数超过预设次数阈值时，将当前所处的小区确定为网络连接失败的小区。In the first possible way, when the current mobile network corresponding to the second SIM card of the terminal is interrupted, that is, when the network connection fails, the number of connection failures is determined, and when the number of connection failures exceeds the preset number of thresholds, the current The cell identified as the network connection failure cell.
值得注意的是，当检测到网络连接失败时，如果直接将当前所处的小区的TAC添加到TAC禁止列表中，终端将无法再次接入到该小区，特别地，当该当前所处的小区的网络只是短暂出现异常，此时将该当前所处的小区的TAC添加到TAC禁止列表中，导致该小区的网络恢复正常后，终端也无法接入该当前所处的小区。因此，在本公开实施例中，当终端检测到网络连接失败时，记录连接失败次数，并开始计时，当计时时间达到时，重新进行网络连接，如果重新进行网络连接仍然失败，更新连接失败次数，重复开始计时，循环执行上述操作，直至终端接入该第二SIM卡对应的移动网络，或连接失败次数超过预设次数阈值。当连接失败次数超过预设次数阈值时，表明当前所处的小区的网络持续出现异常，此时终端可以将当前所处的小区确定为网络连接失败的小区，并将该当前所处的小区的TAC添加到清空后的TAC禁止列表中，避免终端重复尝试接入该当前所处的小区。It is worth noting that when a network connection failure is detected, if the TAC of the current cell is directly added to the TAC forbidden list, the terminal will not be able to access the cell again, especially when the current cell The network of the terminal is abnormal only for a short time. At this time, the TAC of the current cell is added to the TAC prohibition list, so that the terminal cannot access the current cell after the network of the cell returns to normal. Therefore, in the embodiment of the present disclosure, when the terminal detects that the network connection fails, it will record the number of connection failures and start timing. When the timing time is up, it will re-connect to the network. If the re-connection still fails, the number of connection failures will be updated. , start timing repeatedly, and execute the above operations in a loop until the terminal accesses the mobile network corresponding to the second SIM card, or the number of connection failures exceeds the preset threshold. When the number of connection failures exceeds the preset number threshold, it indicates that the network of the current cell continues to be abnormal. At this time, the terminal can determine the current cell as the cell where the network connection fails, and the current cell The TAC is added to the cleared TAC forbidden list, so as to prevent the terminal from repeatedly attempting to access the current cell.
其中，计时时间为终端中预先设置的时间，该计时时间可以为5s、10s或15s等。预设次数阈值为终端中预先设置的次数，该预设次数阈值可以为5次、10次或20次等。Wherein, the counting time is a preset time in the terminal, and the counting time may be 5s, 10s, or 15s. The preset number of times threshold is a preset number of times in the terminal, and the preset number of times threshold may be 5 times, 10 times, or 20 times, etc.
例如，计时时间为5s，预设次数阈值为5次，当终端检测到网络连接失败时，开始计时，并记录连接失败次数为1次，当计时时间5s达到时，重新进行网络连接，循环执行，如果连接失败次数超过5次，终端仍没有接入该当前所处的小区，表明该当前所处的小区的网络持续出现异常，因此，终端可以将该当前所处的小区确定为网络连接失败的小区。For example, the timing time is 5s, and the preset threshold is 5 times. When the terminal detects that the network connection fails, it will start timing and record the number of connection failures as 1 time. When the timing time reaches 5s, re-connect to the network and execute in a loop , if the number of connection failures exceeds 5 times, the terminal still does not access the current cell, indicating that the network of the current cell continues to be abnormal, so the terminal can determine the current cell as a network connection failure district.
第二种可能的方式，当当前所处的位置发生变化时，检测当前所处小区的信号能量和当前所处小区的邻小区的信号能量，当邻小区的信号能量超过当前所处小区的信号能量时，重新进行网络注册，以接入该邻小区。当接收到网络注册失败消息时，将该邻小区确定为网络连接失败的小区。The second possible way is to detect the signal energy of the current cell and the signal energy of the neighboring cell of the current cell when the current location changes. When the signal energy of the neighboring cell exceeds the signal energy of the current cell When the power is off, re-register the network to access the neighboring cell. When the network registration failure message is received, the neighboring cell is determined as a cell whose network connection fails.
需要说明的是，终端在通过第二SIM卡接入移动网络之后，只有终端处于某个小区的网络覆盖范围时，该终端才能接收到该小区的系统消息。由于相邻小区的网络覆盖范围有交集，因此，终端在当前位置时，除了可以接收当前所处的小区的系统消息，还可以接收其他小区的系统消息，该其他小区也即邻小区。It should be noted that after the terminal accesses the mobile network through the second SIM card, only when the terminal is within the network coverage of a certain cell, the terminal can receive the system message of the cell. Since the network coverages of adjacent cells overlap, when the terminal is at the current location, it can receive system information of other cells besides the system information of the current cell, and the other cells are also neighbor cells.
在第二种可能的方式中，当当前所处的位置发生变化时，终端接收当前所处小区的系统消息和当前所处小区的邻小区的系统消息，根据当前所处小区的系统消息和当前所处小区的邻小区的系统消息，确定当前所处小区的信号能量和当前所处小区的邻小区的信号能量，然后判断是否需要进行位置更新。也即，当邻小区的信号能量超过当前所处小区的信号能量时，终端重新进行网络注册，以接入该邻小区。In the second possible way, when the current location changes, the terminal receives the system message of the cell it is currently in and the system message The system information of the neighboring cells of the cell where the current cell is located determines the signal energy of the cell where the current cell is located and the signal energy of the neighboring cells of the cell where the current cell is located, and then determines whether a location update is required. That is, when the signal energy of the neighboring cell exceeds the signal energy of the current cell, the terminal re-registers with the network to access the neighboring cell.
其中，终端重新进行网络注册，也即，终端向第二SIM卡对应的MME发送该第二SIM卡的身份信息和该邻小区的TAC，当MME接收到第二SIM卡的身份信息和该邻小区的TAC时，判断该邻小区的TAC是否属于禁止该第二SIM卡接入的小区的TAC，当该邻小区的不属于禁止该第二SIM卡接入的小区的TAC时，更新该第二SIM卡的所处小区的TAC，也即，将该邻小区的TAC作为该终端当前所处的小区的TAC，以便MME能够跟踪该终端，并向该终端发送相应业务。当MME更新该第二SIM卡的当前所处小区的TAC时，确定该终端可以通过第二SIM卡接入该邻小区，然后向终端发送网络注册成功消息。Wherein, the terminal performs network registration again, that is, the terminal sends the identity information of the second SIM card and the TAC of the neighboring cell to the MME corresponding to the second SIM card, when the MME receives the identity information of the second SIM card and the TAC of the neighboring cell When the TAC of the cell is used, it is judged whether the TAC of the adjacent cell belongs to the TAC of the cell that prohibits the access of the second SIM card, and when the TAC of the adjacent cell does not belong to the cell that prohibits the access of the second SIM card, update the TAC The TAC of the cell where the SIM card is located, that is, the TAC of the neighboring cell is used as the TAC of the cell where the terminal is currently located, so that the MME can track the terminal and send corresponding services to the terminal. When the MME updates the TAC of the cell where the second SIM card is currently located, it determines that the terminal can access the neighboring cell through the second SIM card, and then sends a network registration success message to the terminal.
相应地，当MME确定该邻小区的TAC属于禁止该第二SIM卡接入的小区的TAC时，确定该终端没有权限通过第二SIM卡接入该邻小区，向终端发送网络注册失败消息。当终端接收到网络注册失败消息时，将该邻小区确定为网络连接失败的小区，并将该邻小区的TAC添加到TAC禁止列表中，避免终端重复通过第二SIM卡接入该邻小区Correspondingly, when the MME determines that the TAC of the neighboring cell belongs to the TAC of a cell prohibited from accessing the second SIM card, it determines that the terminal is not authorized to access the neighboring cell through the second SIM card, and sends a network registration failure message to the terminal. When the terminal receives the network registration failure message, it determines the neighboring cell as a cell whose network connection fails, and adds the TAC of the neighboring cell to the TAC forbidden list, so as to prevent the terminal from repeatedly accessing the neighboring cell through the second SIM card
其中，当前所处小区的系统消息和当前所处小区的邻小区的系统消息包括相应小区的TAC、相应小区所属的PLMN((Public Land Mobile Network，公共陆地移动网络)以及相应小区的信号能量等信息。PLMN用来区分不同的运营商，当终端接收到当前所处小区的邻小区的系统消息时，会先判断该邻小区所属的PLMN是否属于终端签约的PLMN，当邻小区所属的PLMN是终端签约的PLMN时，终端才继续执行是否需要进行位置更新的操作。特别地，当小区所属的PLMN不是终端签约的PLMN时，终端是不可能接入该邻小区的，也即不会执行位置更新的操作。Among them, the system information of the cell where the current cell is located and the system information of the neighbor cell of the cell where the current cell is located include the TAC of the corresponding cell, the PLMN ((Public Land Mobile Network, Public Land Mobile Network) to which the corresponding cell belongs, and the signal energy of the corresponding cell, etc. Information. PLMN is used to distinguish different operators. When the terminal receives the system information of the neighboring cell of the current cell, it will first judge whether the PLMN of the neighboring cell belongs to the PLMN signed by the terminal. When the PLMN of the neighboring cell is Only when the terminal subscribes to the PLMN, the terminal will continue to perform the operation of whether to update the location. In particular, when the PLMN to which the cell belongs is not the PLMN that the terminal subscribes to, it is impossible for the terminal to access the neighboring cell, that is, the location update will not be performed. The updated operation.
