It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
At present, when some communication devices use an operator network to perform network communication, generally, there is a need to bind a SIM card with the communication device, in the prior art, a binding relationship between the SIM card and the communication device is mainly stored in the operator network by an operator, and the operator network verifies the validity between an ICCID of the SIM card and an IMEI of the communication device in a process of registering the communication device in the network; the specific process is as follows: when the SIM card is inserted into the card slot of the communication equipment, the communication equipment reads the ICCID of the SIM card and sends the read ICCID of the SIM card and the IMEI of the communication equipment to an operator network, the operator network verifies the legality between the ICCID of the SIM card and the IMEI of the communication equipment, and a network registration process is carried out under the condition that the ICCID of the SIM card and the IMEI of the communication equipment are in a legal binding relationship.
However, after the binding relationship is determined by the operator, when a developer wants to change the binding relationship, the developer needs to change the binding relationship by the operator, which results in limited use of the SIM card, low versatility, and poor flexibility of binding the SIM card and the communication device.
The machine-card binding method is realized through a communication module in communication equipment, the communication module can provide a machine-card binding function interface for developers, the developers can flexibly set an available SIM card number segment of the communication equipment through the machine-card binding function interface, namely, the ICCID of the SIM card bound with the communication equipment is flexibly set, the application range of the SIM card can be improved, the universality of the SIM card is enhanced, and the flexibility of the machine-card binding of the SIM card and the communication equipment is improved; meanwhile, developers can flexibly set Key parameters through the machine-card binding function interface, and the Key parameters are used for determining PIN codes of the SIM cards, so that the communication equipment can determine the PIN codes of the SIM cards to obtain the use permission of the SIM cards, and the universality of the communication module is greatly improved.
The machine-card binding method provided by the application can be applied to the application environment shown in fig. 1. The communication device 101 communicates with the carrier network 102, and network registration and normal network communication of the communication device 101 are realized.

The communication device 101 in this embodiment may adopt a structure diagram as shown in fig. 2, where the communication device 101 includes a communication module 201, and the communication module 201 may specifically be any one of a 2G communication module, a 3G communication module, a 4G communication module, a 5G communication module, and an NB-IOT communication module; the communication module 201 is provided with a card slot 202 into which a SIM card can be inserted, and the communication module 201 is configured to detect whether the SIM card is inserted into the card slot 202, check validity of the SIM card when the SIM card is detected to be inserted, and perform network registration when the SIM card is legal.
In addition, the communication module in the embodiment of the application can provide a machine-card binding function interface for developers, so that the developers can flexibly set the SIM card number segment and the Key parameter bound with the communication equipment through the machine-card binding function interface, and machine-card binding of the communication equipment and the SIM card is realized.
In an embodiment, as shown in fig. 3, a machine-card binding method is provided, which is described by taking the method as an example applied to the communication module in fig. 2, and includes the following steps:
step 301, reading the ICCID of the SIM card in the communication module, and determining whether the ICCID is valid.
The communication equipment comprises a communication module, wherein the communication module is provided with a card slot capable of inserting the SIM card, and the communication module can judge whether the SIM card is inserted or not by detecting the level change of pins in the card slot; the ICCID of the SIM card is used as the unique identification code of the SIM card, and the ICCID of the SIM card uniquely bound with the communication device may be stored in advance in the communication module, so as to realize one-to-one binding between the communication device and the SIM card.
In an optional implementation process of this embodiment, when the communication module detects that an SIM card is inserted into the card slot, it may read an ICCID of the SIM card and determine whether the ICCID is legal; optionally, by determining whether the read ICCID of the SIM card is the same as the ICCID of the uniquely bound SIM card prestored in the communication module, in the case that the read ICCID of the SIM card is determined to be the same as the ICCID of the uniquely bound SIM card prestored in the communication module, it may be determined that the SIM card is the SIM card bound to the communication device, and it may also be determined that the read ICCID of the SIM card is legal.
And step 302, if the ICCID of the SIM card is legal, determining a target PIN code according to the ICCID of the SIM card and a Key parameter which is written into the communication module in advance.
In the development stage of the communication equipment, a developer can preset a Key parameter and write the Key parameter into a communication module of the communication equipment, wherein the Key parameter is used for calculating a PIN code of an SIM card, a program algorithm used for calculating the PIN code of the SIM card is prestored in the communication module, and the program algorithm can calculate the PIN code of the SIM card according to the ICCID of the SIM card and the Key parameter.
In an optional implementation process of this embodiment, when determining that the ICCID of the SIM card is valid, the communication module may determine the target PIN code according to the ICCID of the SIM card and the Key parameter written in the communication module in advance; that is, the communication module inputs the ICCID and Key parameters of the SIM card into the program algorithm, and obtains the target PIN code of the SIM card after calculation by the program algorithm.
Step 303, sending the target PIN code to the SIM card, and initiating a network registration procedure when the target PIN code is determined to be legal by the SIM card.
The PIN code of the SIM card is used as the security password of the SIM card, and after the PIN code of the SIM card is set, the normal network registration and network communication can be carried out by using the SIM card only by correctly inputting the PIN code of the SIM card.
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 after verifying the validity of the target PIN code, the SIM card sends feedback information to the communication module, and when the feedback information is that the target PIN code is valid, the communication module may initiate a network registration procedure to obtain a network service of an operator; however, when the feedback information is that the target PIN code is illegal, the communication module cannot initiate a network registration process to the operator network, so that the communication module cannot acquire the network service of the operator.
In the machine-card binding method, a communication module reads an ICCID of an SIM card in the communication module and determines whether the ICCID is legal, under the condition that the ICCID of the SIM card is legal, a target PIN code is determined according to the ICCID of the SIM card and a Key parameter written into the communication module in advance, the target PIN code is sent to the SIM card, and under the condition that the target PIN code is legal, a network registration process is initiated; that is to say, in the embodiment of the present application, a developer can implement a binding relationship between a communication device and an SIM card through a communication module, and does not need to set the binding relationship between the communication device and the SIM card through an operator, so that the flexibility of binding the communication device and the SIM card is greatly improved, the developer can flexibly change the binding relationship between the communication device and the SIM card, and the universality of the SIM card is further improved; in addition, in the embodiment of the application, the validity of the ICCID of the SIM card is judged through the communication module, that is, whether the binding relationship between the communication device and the SIM card is legal is judged through the communication module, the IMEI of the communication device and the ICCID of the SIM card do not need to be sent to the operator network, the operator network checks whether the machine-card binding relationship between the communication device and the SIM card is legal, and the network registration process is directly performed under the condition that the ICCID of the SIM card is legal and the target PIN code of the SIM card is legal, so that the network registration rate of the communication device for the operator is greatly improved.
Fig. 4 is a flowchart illustrating a machine-card binding method according to another embodiment. This embodiment relates to an alternative implementation of the communication module determining whether the ICCID is valid. On the basis of the above embodiment, as shown in fig. 4, the step 301 includes:
step 401, detecting whether the ICCID is in a preset SIM card number segment.
In an optional implementation process of this embodiment, a developer may further set a SIM card number segment bound to the communication device, where the SIM card number segment includes ICCIDs of multiple SIM cards, and store the SIM card number segment in a communication module, so as to implement one-to-many binding between the communication device and the SIM cards; that is, the communication device may bind not only the ICCID of one SIM card but also the ICCIDs of multiple SIM cards, that is, the communication device may implement registration of an operator network through the bound multiple SIM cards. When the communication module detects that the SIM card is inserted, the communication module reads the ICCID of the SIM card and detects whether the ICCID of the SIM card is in a preset SIM card number segment to determine whether the SIM card is legal.
Step 402, if the ICCID is in the preset SIM card number segment, determining that the ICCID is legal.
In this embodiment, the communication module determines that the ICCID is valid by detecting whether the ICCID is in a preset SIM card number segment or not, when the ICCID is in the preset SIM card number segment; that is to say, in the embodiment of the present application, in the case that the SIM card number segment having a binding relationship with the communication device is pre-stored in the communication module, it may be determined whether the binding relationship between the SIM card and the communication device is legal through the communication module without sending the ICCID of the SIM card and the IMEI of the communication device to the carrier network, and the carrier network determines whether the binding relationship between the SIM card and the communication device is legal, so that communication between the communication device and the carrier network is reduced, and a verification rate of the binding relationship between the SIM card and the communication device is greatly improved.
Fig. 5 is a flowchart illustrating a machine-card binding method in another embodiment. The present embodiment relates to an optional implementation process for determining whether the target PIN code is legal or not by the communication module before initiating a network registration procedure under the condition that 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 the PIN code is stored in the SIM card, detecting whether the PIN code stored in the SIM card is the same as the target PIN code through the SIM card, and determining that the target PIN code is legal under the condition that the PIN code stored in the SIM card is the same as the target PIN code.
When an operator issues an SIM card, an initial PIN code is set for the SIM card, the SIM card is in a PIN locking state if the PIN locking function of the SIM card is activated by inputting the initial PIN code in the using process of the SIM card, and after the initial PIN code in the SIM card is modified, a modified new PIN code is stored in the SIM card, that is, a user can set the new PIN code to be stored in the SIM card, and when the SIM card is inserted into communication equipment, the SIM card can be used only by correctly inputting the new PIN code. If the PIN locking function of the SIM card is not activated, the SIM card is not in a PIN locking state, and the SIM card can be used without inputting a PIN code when the SIM card is inserted.
In an optional implementation process of this embodiment, when the communication module determines that the ICCID of the SIM card is valid, the communication module reads the state of the SIM card to determine whether the SIM card is in a PIN lock state; when the SIM card is in a PIN locking state, namely, when a PIN code is stored in the SIM card, the communication module tries to solve the PIN; after the communication module sends the target PIN code to the SIM card, the SIM card can detect whether the PIN code stored in the SIM card is the same as the target PIN code or not, and under the condition that the PIN code stored in the SIM card is the same as the target PIN code, the fact that the PIN decoding is successful is determined, namely the fact that the target PIN code is legal is determined.
Step 502, if the PIN code is not stored in the SIM card, it is determined that the target PIN code is legal.
In an optional implementation process of this embodiment, when determining that the SIM card is not in the PIN locking state, that is, the SIM card does not store the PIN code, the communication module may directly use the SIM card to perform network registration, that is, may directly determine that the target PIN code is legal.
In this embodiment, the communication module detects, by the SIM card, whether the PIN code stored in the SIM card is the same as the target PIN code under the condition that the PIN code is stored in the SIM card, and determines that the target PIN code is legal under the condition that the PIN code stored in the SIM card is the same as the target PIN code; and determining that the target PIN code is legal under the condition that the PIN code is not stored in the SIM card; that is to say, in this embodiment, regardless of whether the PIN code is stored in the SIM card, the communication module can verify the validity of the target PIN code, and in the case that the PIN code is stored in the SIM card, by determining that the target PIN code is valid, the successful PIN decoding of the SIM card, that is, the use permission of the SIM card is possessed, so that the universality between the communication device and the SIM card is improved.
In an optional embodiment of the present application, in a case that the PIN code is not stored in the SIM card, the communication module may further write the target PIN code into the SIM card, so as to implement PIN locking on the SIM card, and prevent other communication devices from abusing the SIM card, which may result in the information of the SIM card being stolen. For example: when the PIN locking function of the SIM card is not activated, that is, the SIM card is not in the PIN locking state, and the PIN code is not stored in the SIM card, after the SIM card is inserted into the communication module a in the embodiment of the present application, the communication module a may activate the PIN locking function of the SIM card, and store the target PIN code a in the SIM card, so that when the SIM card is used in the communication module B, the SIM card is in the PIN locking state, and the target PIN code a is stored in the SIM card at this time; if the Key parameter in the communication module B is the same as the Key parameter in the communication module a, the communication module B determines that the target PIN code B is the same as the target PIN code a according to the ICCID of the SIM card and the Key parameter, and the communication module B can successfully decode the PIN of the SIM card; that is, many-to-many binding between the communication equipment 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, the communication module B determines that the target PIN code B is different from the target PIN code a according to the ICCID of the SIM card and the Key parameter, and if the communication module B fails to release the PIN from the SIM card, the communication module B cannot use the SIM for network registration, thereby avoiding the situation that the information of the SIM card is stolen.
In this embodiment, the communication module writes the target PIN code into the SIM card when the PIN code is not stored in the SIM card, so that PIN locking of the SIM card can be achieved, malicious registration of the SIM card and theft of information of the SIM card are prevented, and security of the SIM card is improved.
According to the above discussion of step 501, optionally, in the case that the SIM card stores a PIN code, if 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, and if the PIN code stored in the SIM card is not the same as the target PIN code, it indicates that the communication module fails to decode the PIN, that is, in the case that the communication module determines that the target PIN code is illegal through the SIM card, the communication module may add the ICCID of the SIM card to a list of invalid SIM cards prestored in the communication module, so as to prevent that the SIM card is permanently locked due to failure of multiple times of PIN decoding.
Fig. 6 is a flowchart illustrating a machine-card binding method according to another embodiment. The embodiment relates to an optional implementation process for determining a target PIN code by a communication module according to the ICCID of the SIM card and a Key parameter written into the communication module in advance. On the basis of the above embodiment, as shown in fig. 6, the step 302 includes:
step 601, if the SIM card stores the PIN code, determining whether the ICCID of the SIM card is in a pre-stored invalid SIM card list.
Step 602, if the ICCID of the SIM card is not in the pre-stored invalid SIM card name list, determining the target PIN code according to the ICCID of the SIM card and the Key parameter.
In an optional implementation process of this embodiment, when the ICCID of the SIM card is not in the pre-stored invalid SIM card list, which indicates that the SIM card has not been tried to decode the PIN by the communication module, the target PIN code may be determined according to the ICCID of the SIM card and the Key parameter, and the PIN is tried to be decoded; optionally, when the ICCID of the SIM card is in a pre-stored invalid SIM card list, the SIM card may be reported to the communication device as an invalid SIM card.
In this embodiment, when determining that the PIN code is stored in the SIM card, the communication module determines whether the ICCID of the SIM card is in a pre-stored invalid SIM card list, and when the ICCID of the SIM card is not in the pre-stored invalid SIM card list, determines the target PIN code according to the ICCID of the SIM card and the Key parameter; that is to say, in this embodiment, before determining the target PIN code, it is determined whether the SIM card is already in the pre-stored invalid SIM card list, and when the SIM card is not in the pre-stored invalid SIM card list, the target PIN code is determined according to the ICCID of the SIM card and the Key parameter, and the PIN decoding is attempted, so that a phenomenon that the SIM card is permanently locked due to the fact that the PIN is continuously decoded when the ICCID of the SIM card is in the pre-stored invalid SIM card list is avoided, a useless operation of the communication module in performing target PIN code calculation is also reduced, and the working efficiency of the communication module is improved.
In an optional embodiment of the present application, the communication module may receive the SIM card number segment and the Key parameter input by the user through a preset machine-card binding function interface, and write the received SIM card number segment and the received Key parameter into the communication module; the SIM card number segment and the Key parameter can be set and changed more conveniently by developers, and the universality and the flexibility of the communication module are greatly improved.
It should be understood that although the various steps in the flow charts of fig. 3-6 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 3-6 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed sequentially, but may be performed alternately or in alternation with other steps or at least some of the other steps or stages.
