Description

An identification method of valid user identification card

technical field

The invention relates to the communication field, in particular to an identification method of an effective user identification card.

Background technique

At present, more and more operators are launching low-priced terminals, and some new marketing methods have emerged, such as free mobile phones with pre-stored calls. In order to ensure that users use their network within a fixed period of time and thus recover costs, operators will adopt the method of "machine-card interlocking" to achieve this goal, locking a special user terminal and a user identification card. After locking, the user terminal can only A corresponding said subscriber identity card can be used.

At present, the most common method of machine-card interlocking is that one user terminal corresponds to one user identification card. This locking method has certain limitations in practical application: after realizing machine-card interlocking, a user identification card can only be effectively used in one user terminal. Obviously, if the user wants to replace a new subscriber identification card or loses the subscriber identification card, it will bring inconvenience to the user; moreover, the locking method of one subscriber terminal corresponding to one subscriber identification card is not conducive to the effective expansion of the market for operators.

Contents of the invention

In view of this, the main purpose of the present invention is to provide a valid subscriber identification card identification method, so that multiple valid subscriber identification cards can be used in the same user terminal, which is convenient for users and beneficial to the development of operators.

In order to achieve the above object, technical solution of the present invention is achieved in that way:

A method for identifying a valid user identification card, the method comprising:

Write fuzzy unlocking data for judging whether the user identification card is valid in the user terminal; read the information in the user identification card, and judge whether the user identification card is sufficient for the user according to the information and the fuzzy unlocking data used in the terminal.

The fuzzy unlocking data is part of the data that can uniquely identify the user identification card.

The data that can uniquely identify the subscriber identity card is ESN or IMSI.

The fuzzy unlocking data exists in the form of information list.

The method of judgment is:

using the information read from the subscriber identification card to search in the fuzzy unlocking data, and if the information read from the subscriber identification card is retrieved in the fuzzy unlocking data, it is determined that the subscriber identification card can be used for the user terminal; otherwise, determine that the subscriber identity card is not available for the user terminal.

The method further includes:

It is determined that the subscriber identity card is not allowed to be used in the user terminal, and the user terminal enters an abnormal working state.

The method further includes:

It is determined that the subscriber identity card is allowed to be used in the user terminal, and the user terminal enters a normal working state.

Before performing the judgment, it is further judged whether the subscriber identification card is in the PIN or PUK code enabled state, and when it is in the enabled state, it is judged whether it is successfully unlocked after inputting the unlock code. normal working condition.

Before performing the determination, it is further determined whether the lock flag of the user terminal has been enabled, and the determination is performed when it is determined that it has been enabled.

The lock flag of the user terminal is not enabled, and the user terminal further enters a normal working state.

It can be seen that the method for identifying a valid subscriber identification card provided by the present invention can write fuzzy unlocking data for judging whether the subscriber identification card is valid into the user terminal; read the information in the subscriber identification card, and based on the information and the described The fuzzy unlocking data judges whether the subscriber identification card is allowed to be used in the user terminal. Therefore, multiple effective subscriber identification cards can be used for the same subscriber terminal. In practical applications, these subscriber identification cards can be subscriber identification cards that operators allow users to use, which makes users only use user terminals in the network operated by operators themselves, which is obviously beneficial to the development of operators; And, when the user wants to replace a new subscriber identification card or the subscriber identification card of the user is lost, the user can still use other subscriber identification cards, as long as the subscriber identification card can be effectively applied to the user terminal, which is obviously convenient User's use.

Detailed ways

The technology of the present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to Fig. 1, Fig. 1 is the flow chart of pre-setting fuzzy unlocking data according to an embodiment of the present invention, and the process includes the following steps:

Step 101: Write fuzzy unlocking data for judging whether the subscriber identification card is valid into the user terminal.

Specifically, after starting the user terminal, the fuzzy unlocking data can be written into the user terminal by means of keyboard input, PC-side software tools, and the like. The fuzzy unlocking data may be part of various data that can uniquely identify the subscriber identification card, such as part of ESN, IMSI and the like.

Step 102: After writing the fuzzy unlocking data, enable the lock flag of the user terminal, indicating that the user terminal has been locked.

After completing the operations shown in Figure 1, you can perform the operations shown in Figure 2. Referring to FIG. 2, FIG. 2 is a flow chart of identifying a valid subscriber identification card according to an embodiment of the present invention, and the process includes the following steps:

Step 201: After the user terminal is started, determine whether the subscriber identification card inserted into the user terminal is in the PIN or PUK code enabled state, if yes, proceed to step 202; otherwise, directly enter step 203.

Step 202: After the user terminal receives the unlock code input by the user, it is judged whether it is successfully unlocked after inputting the unlock code, if yes, go to step 203; otherwise, directly go to step 207.

Step 203: Determine whether the lock flag of the user terminal has been enabled, and if so, go to step 204; otherwise, go to step 208 directly.

Step 204: Read the information in the user identification card.

Step 205: Comparing the information read from the user identification card with the fuzzy unlocking data written into the user terminal in advance.

Step 206: According to the comparison result, it is judged whether the subscriber identity card can be used for the user terminal, and if yes, directly go to step 208; otherwise, go to step 207.

Specifically, the fuzzy unlocking data may exist in the form of an information list, and the information list stores part of the data that can uniquely identify the user identification card, such as part of the ESN information. Then, when performing the comparison operation, the information read from the user identification card can be used to search in the fuzzy unlocking data, if the information read from the user identification card is retrieved in the fuzzy unlocking data The information determines that the subscriber identity card is available for the user terminal; otherwise, determines that the subscriber identity card is not available for the user terminal.

In practical applications, the retrieval operation may be performed by using operation methods such as field retrieval or fuzzy retrieval. For example: assume that the ESN value read from a user identification card is "12345678", and the fuzzy unlocking data written in the user terminal in advance is "1234". Then, during retrieval, data retrieval can be performed in a left-to-right retrieval manner. It can be seen that after searching, it can be determined that all subscriber identification cards whose first four digits of the ESN are "1234" can be used normally in the user terminal.

Step 207: The user terminal enters into an abnormal working state, and ends this process.

Step 208: the user terminal enters a normal working state.

It can be seen from Fig. 1 and Fig. 2 that the principle of the identification method for valid subscriber identification cards is shown in Fig. 3 .

Referring to Fig. 3, Fig. 3 is a schematic flow chart of identifying a valid subscriber identification card of the present invention, and the flow includes the following steps:

Step 301: Write fuzzy unlocking data for judging whether the subscriber identification card is valid into the user terminal in advance.

Step 302: Read the information in the subscriber identification card, and judge whether the subscriber identification card is allowed to be used in the user terminal according to the information and the fuzzy unlocking data.

Generally, a subscriber identity card that is allowed to be used in a user terminal can be called a valid subscriber identity card.

It can be seen from the above description that the method for identifying a valid subscriber identification card provided by the present invention enables multiple valid subscriber identification cards to be used in the same user terminal. In practical applications, these subscriber identification cards can be subscriber identification cards that operators allow users to use, which makes users only use user terminals in the network operated by operators themselves, which is obviously beneficial to the development of operators; And, when the user wants to replace a new subscriber identification card or the subscriber identification card of the user is lost, the user can still use other subscriber identification cards, as long as the subscriber identification card can be effectively applied to the user terminal, which is obviously convenient User's use.
