Detailed ways

In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

Nowadays, when some communication devices use the operator network for network communication, there is generally a binding requirement between the SIM card and the communication device. When binding the communication device and the SIM card through the operator, the operator will combine the International Mobile Equipment Identity (IMEI) of the communication device with the integrated circuit card identity of the SIM card (Integrate circuit card identity, ICCID for short) is correspondingly stored in the operator network. When the communication device inserts the SIM card, it will send the read ICCID of the SIM card and the IMEI of the communication device to the operator network, so that the operator network can verify the SIM card and the machine card of the communication device. Whether the binding relationship is legal, and if legal, perform network registration.

At present, the binding relationship between the SIM card and the communication device is mainly stored in the operator's network through the operator, and the operator's network verifies the legality between the ICCID of the SIM card and the IMEI of the communication device during the process of registering the communication device to the network. The specific process is: when the SIM card is inserted into the card slot of the communication device, the communication device reads the ICCID of the SIM card, and sends the read ICCID of the SIM card and the IMEI of the communication device to the operator network, The operator network verifies the validity between the ICCID of the SIM card and the IMEI of the communication device, and performs a network registration process when the ICCID of the SIM card and the IMEI of the communication device are in a legal binding relationship.

However, the binding of the SIM card and the communication device is performed through the operator. After the binding relationship is determined, when the developer wants to change the binding relationship, he must change the binding relationship through the operator, resulting in limited use of the SIM card. , the versatility is low, and the flexibility of binding the SIM card to the machine card of the communication device is also poor. Therefore, in the current method for binding a SIM card and a communication device through the operator network, it is not easy to modify the binding relationship after the binding relationship is determined, and the communication device can only use the SIM card bound to it, resulting in the SIM card being bound to the SIM card. The versatility of the card is low, which in turn results in poor flexibility in binding the SIM card to the machine card of the communication device.

The machine-card binding method provided by the present application is realized by a communication module in a communication device, and the communication module is, for example, a wireless communication module or a wireless cellular communication module. For example, the communication module integrates chips, memory, power amplifier devices, etc. on the circuit board, and provides functional circuits with standard interfaces, so that communication devices can realize communication functions with the help of the communication module. The communication module can provide developers with a machine-card binding function interface, and developers can flexibly set the SIM card number segment that can be used by the communication device through the machine-card binding function interface, that is, flexibly set the SIM card number that is bound to the communication device. The ICCID of the SIM card can add the SIM card that the communication device can use or the communication device that the SIM card can apply to, enhance the versatility of the SIM card, and improve the flexibility of the SIM card and the machine card binding of the communication device; at the same time , the developer can also flexibly set the Key parameter through the machine card binding function interface, the Key parameter is used to determine the PIN code of the SIM card, so that the communication device can determine the PIN code of each SIM card, and obtain the use authority of the SIM card, The versatility of the communication module is greatly improved.

There is a card slot 202 capable of inserting a SIM card in this communication module 201, and this communication module 201 is used to detect whether a SIM card is inserted in this card slot 202, and when detecting that a SIM card is inserted, verify this SIM The validity of the card, and if the SIM card is legal, perform network registration.

In addition, the communication module in the embodiment of the present application can provide developers with a machine-card binding function interface, so that developers can flexibly set the SIM card number segment bound to the communication device through the machine-card binding function interface and the Key parameter to realize the machine card binding between the communication device and the SIM card.

In one embodiment, as shown in FIG. 3, a machine-card binding method is provided, and the method is applied to the communication module in FIG. 2 as an example to illustrate, including the following steps:

Step 301, read the ICCID of the SIM card, and determine whether the ICCID of the SIM card is legal.

In one embodiment, the communication device includes a communication module, the communication module has a card slot capable of inserting a SIM card, and the SIM card is a SIM card inserted into the card slot of the communication module. The communication module can judge whether a SIM card is inserted by detecting the level change of the pins in the card slot. The ICCID of the SIM card is the unique identification code of the SIM card. In the communication module, the ICCID of the SIM card uniquely bound to the communication device can be pre-stored through the memory in the communication module, so as to realize the one-to-one binding between the communication device and the SIM card.

In an optional implementation process of this embodiment, when detecting that a SIM card is inserted into the card slot, the communication module can read the ICCID of the SIM card, and determine whether the ICCID is legal; optionally, It can be judged whether the ICCID of the read SIM card is the same as the predetermined ICCID of the uniquely bound SIM card pre-stored in the communication module. When the predetermined ICCIDs of the bound SIM cards are the same, it can be determined that the SIM card is the SIM card bound to the communication device, and it can also be determined that the ICCID of the read SIM card is legal.

Step 302, if the ICCID of the SIM card is legal, determine the target PIN code according to the ICCID of the SIM card and the Key parameter pre-stored in the communication module.

Wherein, in the development stage of the communication device, the developer can preset the Key parameter, and store the Key parameter in the communication module of the communication device, specifically, store the Key parameter in the memory of the communication module (for example, non-volatile memory). In this context, "stored to the communication module" means storage to the memory of the communication module. The Key parameter is used to calculate the PIN code of the SIM card, and a program algorithm for calculating the PIN code of the SIM card is pre-stored in the communication module. The program algorithm can be calculated according to the ICCID of the SIM card and the Key parameter. The PIN code of the SIM card.

In an optional implementation process of this embodiment, when the communication module determines that the ICCID of the SIM card is legal, the communication module may determine the target according to the ICCID of the SIM card and the Key parameter pre-stored in the communication module PIN code; that is, the communication module inputs the ICCID and Key parameters of the SIM card into the above program algorithm, and after the calculation of the program algorithm, the target PIN code of the SIM card is obtained.

Step 303: Send the target PIN code to the SIM card, and initiate a network registration process when it is determined by the SIM card that the target PIN code is valid.

The PIN code of the SIM card is the security password of the SIM card. After the PIN code of the SIM card is set, it is necessary to input the PIN code of the SIM card correctly so that the SIM card can be used for normal network registration and network communication.

In an optional implementation process of this embodiment, after obtaining the target PIN code of the SIM card, the communication module may send the target PIN code to the SIM card, and the SIM card can send the target PIN code to the SIM card. After verifying the validity, send feedback information to the communication module. In the case that the feedback information is valid for the target PIN code, the communication module can initiate a network registration process to obtain the network service of the operator; however, in this When the feedback information is that the target PIN code is invalid, the communication module cannot initiate a network registration process to the operator's network, so that the communication module cannot obtain the operator's network service.

In the above machine-card binding method, the communication module determines whether the ICCID is legal by reading the ICCID of the SIM card in the communication module. Store the Key parameter of the communication module, determine the target PIN code, send the target PIN code to the SIM card, and initiate a network registration process when the target PIN code is determined to be legal through the SIM card; that is to say In the embodiment of the present application, developers can realize the binding relationship between the communication device and the SIM card through the communication module, without setting the binding relationship between the communication device and the SIM card through the operator, which greatly improves the relationship between the communication device and the SIM card. The flexibility of SIM card binding enables developers to flexibly change the binding relationship between the communication device and the SIM card, thereby improving the versatility of the SIM card; in addition, in the embodiment of the present application, the communication module is used to determine the SIM card The legitimacy of the ICCID of the card, that is, through the communication module to determine whether the binding relationship between the communication device and the SIM card is legal, it is not necessary to send the IMEI of the communication device and the ICCID of the SIM card to the operator's network. Verify whether the machine-card binding relationship between the communication device and the SIM card is legal, and directly carry out the network registration process under the condition that the ICCID of the SIM card and the target PIN code of the SIM card are legal, which greatly improves the communication equipment for operators. The rate of network registration.

FIG. 4 is a schematic flowchart of a machine-card binding method in another embodiment. This embodiment relates to an optional implementation process for the communication module to determine whether the ICCID is legal. On the basis of the foregoing embodiment, as shown in FIG. 4 , the foregoing step 301 includes:

Step 401, detecting whether the ICCID is within the preset SIM card number segment.

In an optional implementation process of this embodiment, the developer can also set a SIM card number segment bound to the communication device, the SIM card number segment contains multiple predetermined ICCIDs, and store the SIM card number segment in the communication device In the module, to achieve one-to-many binding between the communication device and the SIM card; that is, the communication device can not only bind the ICCID of one SIM card, but also bind the ICCID of multiple SIM cards, that is, the Multiple SIM cards can be bound to the communication device, and can be registered with the operator's network. When detecting that a SIM card is inserted, the communication module reads the ICCID of the SIM card, and detects whether the ICCID of the SIM card is within the preset SIM card number segment to determine whether the SIM card is legal.

Step 402, if the ICCID is within the preset SIM card number segment, it is determined that the ICCID is valid.

In this embodiment, the communication module determines whether the ICCID is within the preset SIM card number segment by detecting whether the ICCID is within the preset SIM card number segment, and determines that the ICCID is valid; that is, in the embodiment of the present application , in the case that the SIM card number segment with the binding relationship with the communication device has been pre-stored in the communication module, it can be judged whether the binding relationship between the SIM card and the communication device is legal through the communication module. Therefore, it is no longer necessary to send the ICCID of the SIM card and the IMEI of the communication device to the operator's network, and the operator's network can determine whether the binding relationship between the SIM card and the communication device is legal, which reduces the number of gaps between the communication device and the operator's network. communication, which greatly improves the verification rate of the binding relationship between the SIM card and the communication device.

FIG. 5 is a schematic flowchart of a machine-card binding method in another embodiment. This embodiment relates to an optional implementation process in which the communication module determines whether the target PIN code is legal before initiating a network registration process when the SIM card determines that the target PIN code is legal. On the basis of the above embodiment, as shown in FIG. 5 , this aspect further includes:

Step 501, if a PIN code is stored in the SIM card, then the SIM card is used to detect whether the PIN code stored in the SIM card is the same as the target PIN code, and the PIN code stored in the SIM card is the same as the target PIN code. In the case of , it is determined that the target PIN code is valid.

Wherein, when the operator issues the SIM card, it will set the initial PIN code for the SIM card for the SIM card. During the process of using the SIM card, if the PIN of the SIM card is activated by entering the initial PIN code Lock function, the SIM card is in PIN lock state. After the initial PIN code in the SIM card is modified, a new modified PIN code will be stored in the SIM card, that is, the user can set a new PIN code to be stored in the SIM card. When the SIM card is inserted into the communication device, if the PIN lock function of the SIM card is activated, a new PIN code needs to be entered correctly before the SIM card can be used. If the PIN lock function of the SIM card is not activated, the SIM card is not in a PIN lock state, and when the SIM card is inserted, the SIM card can be used without entering a PIN code.

In an optional implementation process of this embodiment, when the communication module determines that the ICCID of the SIM card is legal, it will read the status of the SIM card to determine whether the SIM card is in a PIN locked state; The SIM card is in a PIN lock state, that is, when the SIM card stores a PIN code, the communication module attempts to release the PIN lock state; after the communication module sends the above target PIN code to the SIM card, the SIM card will detect Whether the PIN code stored in the SIM card is the same as the target PIN code, and if the PIN code stored in the SIM card is the same as the target PIN code, it is determined that the PIN lock state is successfully released, that is, the target PIN code is determined to be valid.

Step 502, if the SIM card does not store a PIN code, it is determined that the target PIN code is valid.

In an optional implementation process of this embodiment, when the communication module determines that the SIM card is not in a PIN-locked state, that is, when the SIM card does not store a PIN code, the communication module can directly use the SIM card for network connection After registration, it can be directly determined that the target PIN code is legal.

In this embodiment, when the PIN code is stored in the SIM card, the communication module detects whether the PIN code stored in the SIM card is the same as the target PIN code sent from the communication module through the SIM card. When the PIN code stored in the SIM card is the same as the target PIN code, it is determined that the target PIN code is legal; and when the SIM card does not store the PIN code, it is determined that the target PIN code is legal; that is Said, in this embodiment, no matter whether the PIN code is stored in the SIM card, the communication module can realize the verification of the legitimacy of the target PIN code, and in the case where the PIN code is stored in the SIM card , by determining that the target PIN code is valid, the SIM card can be successfully released from the PIN lock state, that is, the SIM card has the right to use the SIM card, which improves the commonality between the communication device and the SIM card.

In an optional embodiment of the present application, in the case where the SIM card does not store a PIN code, the communication module may also write the target PIN code into the SIM card, so as to realize the SIM card PIN lock to prevent other communication devices from abusing the SIM card, resulting in the theft of the SIM card information. For example: when the PIN lock function of the SIM card is not activated, that is, the SIM card is not in the PIN lock state, and the SIM card does not store a PIN code, the SIM card is inserted into the communication module A in the embodiment of the present application. Then, the communication module A can activate the PIN locking function of the SIM card, and store the target PIN code A1 in the SIM card, so that when the SIM card is used for the communication module B, the SIM card is in the PIN locking state state, and the target PIN code A1 will be stored in the SIM card at this time; Suppose, when the Key parameter in the communication module B is the same as the Key parameter in the communication module A, then the communication module B according to the SIM The ICCID of the card and the Key parameter, the determined target PIN code B1 is the same as the target PIN code A1, and the communication module B can successfully unlock the PIN lock state of the SIM card; that is, by storing the same Key in different communication modules parameter, the many-to-many binding between the communication device and the SIM card can be realized; however, when the Key parameter in the communication module B is different from the Key parameter in the communication module A, then the communication module B according to The ICCID of the SIM card and the Key parameter stored in the communication module B, the determined target PIN code B1 is different from the target PIN code A1, and the communication module B cannot release the PIN lock state of the SIM card, then the communication module B Therefore, the SIM card cannot be used for network registration, and the information of the SIM card can be prevented from being stolen.

In this embodiment, the communication module can realize the PIN locking of the SIM card by writing the target PIN code into the SIM card when the PIN code is not stored in the SIM card, preventing the SIM card Malicious registration and the theft of information on the SIM card improve the security of the SIM card.

According to the discussion of the above-mentioned step 501, optionally, in the case where the PIN code is stored in the SIM card, when the communication module detects whether the PIN code stored in the SIM card is the same as the target PIN code through the SIM card, If the PIN code stored in the SIM card is different from the target PIN code, it means that the communication module cannot release the PIN lock state, that is, when the communication module determines that the target PIN code is illegal through the SIM card, it can be The ICCID of the SIM card is added to the list of invalid SIM cards pre-stored by the communication module, so as to prevent the failure of unlocking the PIN lock state for many times, resulting in permanent locking of the SIM card.

FIG. 6 is a schematic flowchart of a machine-card binding method in another embodiment. This embodiment relates to an optional implementation process in which the communication module determines the target PIN code according to the ICCID of the SIM card and the Key parameter pre-stored in the communication module. On the basis of the foregoing embodiment, as shown in FIG. 6 , the foregoing step 302 includes:

Step 601, if the SIM card stores a PIN code, determine whether the ICCID of the SIM card is in a pre-stored list of invalid SIM cards.

Step 602, if the ICCID of the SIM card is not in the pre-stored list of invalid SIM cards, then determine the target PIN code according to the ICCID of the SIM card and the Key parameter.

The pre-stored list of invalid SIM cards may be a list of ICCIDs of SIM cards pre-stored in the communication module. In an optional implementation process of this embodiment, when the ICCID of the SIM card is not in the pre-stored list of invalid SIM cards, it means that the SIM card has not been tried to release the PIN lock state by the communication module, then the SIM card can be unlocked according to the The ICCID of the SIM card and the Key parameter, determine the target PIN code, and try to release the PIN lock state; optionally, when the ICCID of the SIM card is in the pre-stored list of invalid SIM cards, the communication device can report the The SIM card is invalid.

In this embodiment, when the communication module determines that the PIN code is stored in the SIM card, it determines whether the ICCID of the SIM card is in the pre-stored list of invalid SIM cards, and if the ICCID of the SIM card is not in the pre-stored list of invalid SIM cards In the middle, the target PIN code is determined according to the ICCID of the SIM card and the Key parameter; that is, in this embodiment, before the target PIN code is determined, it will be judged whether the SIM card is already in the pre-stored list of invalid SIM cards , when the SIM card is not in the pre-stored list of invalid SIM cards, the target PIN code is determined according to the ICCID of the SIM card and the Key parameter, and the PIN lock state is attempted to be released to avoid the ICCID of the SIM card being in the lock state. When the pre-stored list of invalid SIM cards is in the list, the SIM card is permanently locked due to the continuous attempt to release the PIN lock state, which also reduces the useless operation of the communication module to calculate the target PIN code, and improves the communication module's performance. work efficiency.

In an optional embodiment of the present application, the communication module may receive the predetermined ICCID input by the user as the preset SIM card number segment and the Key parameter through the preset machine-card binding function interface, and will receive the The predetermined ICCID and the Key parameter are stored in the communication module; for example, multiple predetermined ICCIDs can be input as the preset SIM card number segment. Wherein, the predetermined ICCID is used to compare with the read ICCID of the SIM card to determine whether the ICCID of the SIM card is legal. In this way, developers can more conveniently set and change the predetermined ICCID and the Key parameter stored in the communication module, which greatly improves the versatility and flexibility of the communication module.
