An embodiment of the present application relates to a user data query method, which is applied to a management device. The structure of the management device is as shown in Figure 1, including: an intelligent user interface (Intelligent User Interface, UI), a user data query module, and a data collection module , a data processing module, wherein the UI includes: a query parameter interface and a result presentation interface.

Specifically, the UI is used to input the user number to be queried and the conditions required for the user data to be queried, wherein the conditions required for the user data to be queried include: the business type of the user data to be queried, for example, registration subscription data, dynamic data, etc.

Wherein, the UI is also used to present the result of the response data of the user data query instruction.

The user data query module is used to obtain the target user data management network element to which the user belongs according to the user data to be queried; send a user data query command to the target user data management network element, for the target user data management network element to respond to the user data query command and /or transmit the user data query instruction to the associated network element where the user is located.

In an example, before the user data query module sends the user data query command to the target user data management network element, it is also used to generate a key pair for encrypting and decrypting the response data.

The data collection module is configured to receive response data from the target user data management network element and/or the associated network element where the user is located to the user data query instruction.

The data processing module is used to obtain the response data of the user data query instruction according to the user data to be queried, decrypt and analyze the response data, and obtain the result of the response data.

The implementation flowchart of the user data query method of the present embodiment is shown in Figure 2, specifically including:

Step 201, according to the user data to be queried, obtain the target user data management network element to which the user belongs.

Step 202, sending a user data query instruction to the target user data management network element, so that the target user data management network element responds to the user data query instruction and/or transmits the user data query instruction to an associated network element where the user is located.

Step 203, receiving response data from the target user data management network element and/or the associated network element where the user is located to the user data query instruction.

In this embodiment, first, according to the user data to be queried, the target user data management network element to which the user belongs is obtained, and a user data query instruction is sent to the target user data management network element for the target user data management network element to respond to the user data query command and/or transmit the user data query instruction to the associated network element where the user is located, and finally receive the response data from the target user data management network element and/or the associated network element where the user is located to the user data query instruction. In the embodiment of the present application, when querying various user data, since the target user data management network element includes the location of the user, the management device can send the target user data management network element to the target user data management network element by obtaining the target user data management network element to which the user belongs. send the user data query command, and transmit the user data query command to the associated network element where the user is located through the target user data management network element, without sending the user data query command of a single user to all relevant network elements, that is, it can receive the user data query command from The target user data management network element and/or the response data of the associated network element where the user is located to the user data query command, and only sends the user data query command to the network element where the user is located, without affecting the performance of other network elements.

The implementation details of the user data query method in this embodiment are described in detail below, and the following content is only implementation details provided for easy understanding, and is not necessary for implementing this solution.

In step 201, the management device organizes the query parameters of the user data to be queried according to the required conditions and the user number of the user data to be queried, for example, the type of network element involved in the user data to be queried, and according to the The conditions required for the user data to be queried and the user number to obtain the target user data management network element to which the user belongs, wherein the target user data management network element is used to manage user data, including the location of the user data to be queried.

In step 202, the management device sends a user data query instruction to the acquired target user data management network element, so that the target user data management network element responds to the user data query instruction and/or transmits the user data query instruction to the associated network element where the user is located . Wherein, the target user data management network element includes: HLR, HSS or UDM.

Wherein, the user data query command carries the user number input by the user, and the user number is used for the target user data management network element to query the user data and/or query the associated network element where the user is located. The user data query command also carries the network element type used to indicate the user data involved, for the target user data management network element to decide whether to transmit the user data query command to the associated network element where the user is located.

Specifically, after the management device sends the user data query instruction to the acquired target user data management network element, the target user data management network element will determine the target network where the user data to be queried is located according to the user number carried in the user data query instruction. Yuan. Wherein, the target network element may be the target user data management network element, or any one of other associated network elements where the user is located. For example, the user data is in the target user data management network element, or the user data is in the target user data management network element. The data management network element and the associated network element where the user resides.

It should be noted that, after the target user data management network element determines that the target network element where the user data to be queried is located, the target user data management network element can decide whether to send the user data to the associated network element where the user is located according to the network element type involved in the user data. Meta pass user data query command.

For example, the target user data management network element is HLR. After receiving the user data query instruction, the HLR transmits the user data query instruction to the associated network element where the user to which the user data belongs is: HLR->MSC Server->BSC/ RNC, if the network element types involved in the user data are HLR, MSC Server, BSC/RNC, the target user data management network element HLR will pass the user data query command to the user after receiving the user data query command sent by the management device The associated network element MSC Server where the user is located, and the MSC Server transmits the received query command to another associated network element BSC/RNC where the user is located. If the network element types involved in the user data are HLR and MSC Server, the target user data management network element HLR will pass the user data query command to the associated network element MSC where the user is located after receiving the user data query command sent by the management device. Server, and MSC Server will no longer pass user data query commands to BSC/RNC.

In step 203, after the management device sends the user data query command to the target user data management network element, it will receive response data from the target user data management network element and/or the associated network element where the user is located to the user data query command .

Specifically, if the target user data management network element determines that the target network element where the user data is located is the target user data management network element according to the network element type involved in the user data, the user data query instruction will not be transmitted to the associated network element where the user is located, Therefore, after the management device sends the user data query command to the target user data management network element, it will only receive response data from the target user data management network element to the user data query command. If the target user data management network element determines that the target network element where the user data is located is the target user data management network element and the associated network element where the user is located according to the type of network element involved in the user data, the user data will be transferred to the associated network element where the user is located Inquiry command, therefore, after the management device sends the user data query command to the target user data management network element, it will receive the response data to the user data query command from the target user data management network element and the associated network element where the user is located.

In an example, in order to satisfy data security, before sending the user data query instruction to the target user data management network element, the management device will also generate a key pair for encrypting and decrypting the response data.

Specifically, the management device carries the encryption key of the key pair in the user data query command, sends it to the target user data management network element, and sends the user data to the user after receiving the target user data management network element and/or the associated network element where the user is located. After the response data of the data query instruction, the response data is decrypted according to the decryption key of the key pair.

Wherein, the encryption key is an encryption public key, and the decryption key is a decryption private key. In an example, an asymmetric encryption algorithm is used to generate a key pair for encrypting and decrypting the response data, wherein the asymmetric encryption algorithm may be an RSA encryption algorithm, and the data format of the encrypted data may be Extensible Markup Language (Extensible Markup Language). Language, XML).

In an example, after decrypting the response data according to the decryption key of the key pair, the management device also parses the response data, and presents the parsed response data on the UI for the user to view.

It should be noted that, the above-mentioned examples in this embodiment are illustrations for easy understanding, and do not limit the technical solution of the present application.

In the user data query method of this embodiment, the management system can accurately locate the network element where the user data is located by transmitting the user data query command between network elements, without sending the user data query command to all network elements, which effectively improves the user data query method. The efficiency of user data query, while avoiding invalid query on network elements to affect the performance of network elements, to meet the rapid fault location and root cause analysis of user complaints, has great promotion value in the telecommunications industry and related vertical industries. In addition, the user data query method of this embodiment can be applied to the execution and evaluation phase of the Service-Level Agreement (SLA) process, and the current user's service guarantee situation can be checked and optimized in a timely manner through regular user data query and analysis. network.
