Abstract

The invention proposes a user terminal identity identification system and method thereof, which is characterized in that an anti-theft calling module is added to the switching equipment to handle related services of anti-theft calling. Using the user terminal identity recognition method of this system, the user dials the called number, and the switching device judges whether the call needs anti-theft calling service according to the calling and called numbers. If the anti-theft calling service is not required, the switching device connects to the called party; If the anti-theft calling service is required, the anti-theft calling module requires the user to input a password. If the anti-theft calling module verifies that the user's password is correct, the switching device is connected to the called party; if the user's password is incorrectly input, the user is required to re-enter it, and if the input is not correct within the specified number of times, the switching device releases the call. By using the system and the method provided by the invention, the user terminal can be prevented from being stolen, and the user's input habit can not be changed, and the user can freely register and cancel the anti-theft calling service.

Description

A system and method for user terminal identification

technical field

The present invention relates to the field of communication technology, in particular to a system and method for user terminal identification.

Background technique

The development of communication technology has brought convenience to people's life and facilitated people's communication. People only need to use the user terminal to dial the other party's user terminal according to certain rules to realize communication. However, at this stage, user terminals are being stolen, which brings economic losses to real users. Therefore, operators can provide a simple and effective method to prevent real user terminals from being stolen by others.

On the traditional telephone network, there are two common methods used by telecom operators to prevent phone piracy:

The user is restricted from directly dialing the called number that needs to be protected from fraudulent calls. The office opens the prepaid service, and the user pays the fee to the telecom operator by purchasing a prepaid card. When the user wants to dial the called number that needs to be prevented from stealing, he must first dial the prepaid call access code, then input the card number and password, and dial the called number after passing the authentication to realize call connection.

Restrict users from directly dialing the called number that needs to be prevented from stealing, and set an outgoing password for each user. When the user wants to dial the called number that needs to be prevented from stealing, he must call out through the password call service, and dial the new service prefix and password before the called number. Only when the password dialed by the user is correct can the called be continued. If the user dials *42*123456#28780808 to continue the call, where *42* is the new service prefix, 123456 is the user password, and 28780808 is the called number for this call.

Although the above two methods can prevent other people from stealing calls through password authentication, but in the process of use and promotion, the following problems are found:

The following question:

1. The use of these two methods changes the user's dialing habits. The user needs to remember the prepaid call access code, card number, card password or new service prefix, and dial these numbers before each call.

2. If the office wants to activate the prepaid service using the first method above, the operator needs to increase investment in intelligent network-related equipment.

3. The user cannot register or cancel the restriction on the called number that needs to be prevented from fraudulent calling through the phone. If the user needs to use the phone frequently during a certain period of time and does not want to dial a password every time he calls, he must go to the telecommunications business hall to cancel the call restriction, and cannot directly register or cancel it on the phone

Contents of the invention

After the switch supports the anti-theft calling service (identity verification), the user can control the phone password to ensure that only authorized persons can use the phone, preventing other people from stealing or making wrong calls (for example, preventing children from making random calls), and reducing user's inconvenience. Necessary economic loss. Moreover, the user does not need to change the original dialing habit to use the anti-theft calling service, and can also decide whether to activate the anti-theft calling service through the registration and cancellation of the phone at any time.

In order to solve the problem that the user's dialing habit changes and the user cannot independently register and cancel the identity verification service in the existing identity verification system used in the communication field, the present invention proposes a user terminal identity recognition system, which is characterized in that Add an anti-theft calling module on the switching device. After receiving the called number, the module will query in data table A to determine whether the call needs to enable the anti-theft calling function according to the attributes of the calling device and the prefix of the called number. , if it needs to be enabled, start the anti-theft call service after the user has dialed all the called numbers, send a prompt to the calling device to enter the identity verification information, and then judge whether the user terminal is a legal terminal according to the verification information uploaded by the calling device , if it is a legal terminal, connect to the called device; open the anti-theft calling module, which is used to open the identity verification of the call; cancel the anti-theft calling module, which is used to cancel the calling identity verification; modify the identity verification information module, which is used to modify the call identity verification information, and record on the switching device whether the user terminal has identity verification authority, whether the user terminal is registered for identity verification services, user terminal identity verification information, and the attribute values of the three attributes.

The identity verification information in this system is a string of numbers from 0 to 9.

A method for user terminal identification, characterized in that there is a data table A in the user terminal identification system, the data table A stores the terminal number and information on whether to open the anti-theft calling function:

a. The anti-theft calling module receives the called number, and checks in the data table according to the attributes of the calling device and the prefix of the called number to determine whether the anti-theft calling function needs to be enabled for this call. If it needs to be enabled, wait until the user dials all the called numbers. After calling the number, start the anti-theft calling service, and send a prompt to the calling device to enter the identity verification information;

b. The anti-theft calling module receives the user terminal identity verification information from the calling device, judges whether it is a legal terminal, and if it is a legal terminal, connects to the called device.

In step b, if it is verified as an illegal terminal, the calling device is required to re-input the identity verification information, and if the calling terminal is verified as illegal within the specified number of times, the call is released.

In this method, the identity verification information is a string of numbers from 0 to 9.

Wherein the data table A exists on the switching device or on a separate server.

It can be seen from the technical solution of the present invention that by using the system and method provided by the present invention, the user terminal can be prevented from being stolen, without changing the user's input habits, and the user can freely register and cancel the anti-theft service.

Detailed ways

In order to make the object, technical solution, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

On the existing telecommunication network, set the anti-theft calling module inside the switch and add four attributes in the user data table: whether the user has the anti-theft calling service authority, whether the user registers the anti-theft calling service, the user anti-theft calling password, and the user anti-theft calling type attribute (Describe which type of call the user needs to start the anti-theft call process).

During the initialization phase, the system applies for a section of memory for each call to record information related to this call, which we can call a call control block.

Step S01: When the calling user goes off-hook;

Step S02: The switch queries the user data table for all information related to the calling user and the anti-theft calling service, including the anti-theft calling service password, the new calling service authority, whether the new calling service is registered, the type of call that the user needs to prevent theft calling, and It is recorded in the call control block; among them, the user data table stores all the information related to the calling user and the anti-theft calling service, including the anti-theft calling service password, the authority of the new calling service, whether the new calling service is registered or not, and whether the user needs the anti-theft calling service. The call type and other information, the user data table can exist on the switching device or on a separate server.

Step S03: The system continues to wait for the user to dial, when the number dialed by the user can determine the prefix of this call;

Step S04: the call control block analyzes the prefix;

Step S05: If the analysis is unsuccessful, continue to wait for user input;

Step S06: Then, it can be judged whether the call needs anti-theft calling according to the attribute of the calling party and the attribute of the called prefix;

Step S07: If the anti-theft call is not required, execute the normal call flow;

Step S08: If anti-theft calling is required, wait for the user to input the called number;

Step S09: In order not to change the user's dialing habit, the anti-theft calling service must be started after the user has dialed all the called numbers, prompting the user to input the anti-theft calling password;

Step S10: After the user has dialed all the called numbers, the system prompts the user to enter a password;

Step S11: Then the user inputs the anti-theft password;

Step S12: After the user inputs, the system judges the correctness of the password;

Step S13: If the password is correct, the system continues to be called;

Step S14: If the password is incorrect, the system prompts the user that the password is wrong, please re-enter until the maximum number of retries is reached;

Step S15: If the password is still incorrect after reaching the maximum number of times, the system releases the call.

In addition, judging whether the user has dialed all the called numbers can generally be determined by the prefix, because the length of the called number of this call can be known according to the called prefix for general local calls and domestic long-distance calls. For international long-distance calls or other calls that cannot determine the length of the called number based on the prefix, it is considered that the user has dialed all the called numbers when the user's dialing times out.

Register the anti-theft call (identity verification) service: the user picks up the phone and dials the new service prefix and password to register the anti-theft call service, for example, the user dials *15*123456# to register the anti-theft call service. The user must have the anti-theft calling service authority to register the service.

Cancel the anti-theft call (identity verification) service: the user picks up the phone and dials the new service prefix and password to cancel the anti-theft call service, for example, the user dials #15*123456# to cancel the anti-theft call service.

Modify identity verification information: The user picks up the phone and dials the new service prefix, old password, and new password to modify the user's anti-theft password, such as the user dials *541*123456*654321*654321# to change the user's anti-theft password from 123456 to 654321 .

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of changes or modifications within the technical scope disclosed in the present invention. Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
