Description

Technical Field

[0001] The present invention relates to the technical field of the Internet of Things, and in particular to a method, system, device and storage medium for managing area restrictions in the Internet of Things. Background Art

[0002] The area restriction control of the Internet of Things generally realizes by setting in advance the areas where the Internet of Things cards are allowed to be used and directly shutting down the cards when detecting the illegal use of the Internet of Things cards. Then, it is necessary for users to set up the binding relationship in advance, and subsequent users must maintain such a binding relationship during the production and use of the devices, which is difficult to manage. At the same time, some users will have occasional non-subjective illegal behaviors when using Internet of Things devices. The traditional method is to directly shut down the cards. When the users correct the relevant incorrect usage behaviors later, the operator's acceptance personnel need to manually perform the card resumption operation, which to a certain extent achieves the control of the card-device binding. However, the number of devices with Internet of Things cards is huge and the application scenarios are diverse. This solution is relatively rigid in control, with a large later operation and maintenance cost and low efficiency, affecting the user experience. Summary of the Invention

[0022] Further, in an embodiment of the present invention, the step of determining the second area information according to the area binding information, comparing the first area information with the second area information, and then performing Internet of Things area restriction according to the comparison result specifically includes:

[0029] When the comparison is inconsistent, the step of restoring the network connection of the Internet of Things card specifically is:

[0030] Determine the corresponding network element instance according to the first MDN information, generate a blocking connection message according to the network element instance, and send the blocking connection message to the network element task execution layer so that the network element task execution layer blocks the network connection of the Internet of Things network card.

[0049] The following details the embodiments of the present invention. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation of the present invention. For the step numbers in the following embodiments, they are only set for the convenience of explanation and illustration, and no limitation is made on the order between the steps. The execution order of each step in the embodiments can be adaptively adjusted according to the understanding of those skilled in the art.

[0050] In the description of the present invention, the meaning of "a plurality of" is two or more. If the first and second are described, it is only for the purpose of distinguishing technical features and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features. In addition, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present technology.

[0051] Referring to Figure 1 , an embodiment of the present invention provides an Internet of Things area restriction management method, which specifically includes the following steps:

[0052] S101. Obtain a first call detail record message, and determine the first MDN information and the first area information according to the first call detail record message.

[0053] Specifically, the data acquisition and control service collects RADUIS (4G) or CHF (5G) call detail record messages pushed from the upstream system (IT billing) and network elements (PWG), analyzes and extracts the message content to obtain the first MDN (Internet of Things card number) information and the first area information.

[0054] Further as an optional implementation manner, when the first call detail record message is a RADUIS message, the step of determining the first MDN information and the first area information according to the first call detail record message is specifically:

[0055] Parse the first call detail record message, obtain the Calling-Station-Id field and the nFIPv4Address field of the first call detail record message, determine the first MDN information according to the Calling-Station-Id field, determine the corresponding device IP address according to the nFIPv4Address field, and then determine the first area information according to the device IP address.

[0056] Specifically, for the RADUIS call detail record message using the 4G network, the Calling-Station-Id field and the nFIPv4Address field are obtained by parsing the message. The first MDN information can be obtained according to the Calling-Station-Id field, and the nFIPv4Address field is the field used to identify the device IPv4 address in the RADUIS message. The device IP address can be determined according to the nFIPv4Address field, and then the first area information can be obtained according to the relationship comparison table between the device IP address and the province area.

[0057] Further as an optional implementation manner, when the first call detail record message is a CHF message, the step of determining the first MDN information and the first area information according to the first call detail record message is specifically:

[0058] Parse the first call detail record message to obtain the servedGPSI field and the nrCellId field of the first call detail record message. Determine the first MDN information based on the servedGPSI field, determine the corresponding base station ID based on the nrCellId field, and further determine the first area information based on the base station ID.

[0059] Specifically, for the CHF call detail record message using the 5G network, parse the message to obtain the servedGPSI field and the nrCellId field. The first MDN information can be obtained based on the servedGPSI field, and the gNB ID field representing the base station ID is included in the nrCellId field. The base station ID can be determined based on the nrCellId field, and then the first area information can be obtained according to the relationship comparison table between the base station ID and the provincial area.

[0060] It can be understood that the relationship comparison table between the device IP address / base station ID and the identity area can be obtained and stored in advance.

[0061] In some alternative embodiments, after obtaining the parsed first MDN information and the first area message, first determine whether the current user has subscribed to the functional product of "first call area restriction" (area restriction management service based on the embodiments of the present invention) through the first MDN information. If subscribed, continue with the subsequent process. If not subscribed, it can be processed according to the traditional area restriction management method.

[0062] S102. Perform a matching query in the pre-constructed area binding database according to the first MDN information;

[0063] Among them, no area binding information is stored when the area binding database is constructed.

[0064] Specifically, after obtaining the parsed first MDN information and the first area message, perform a matching query in the pre-constructed area binding database according to the first MDN information. Since no area binding information is stored when the area binding database is constructed, if no corresponding area binding information is matched, it means that this call detail record is the first call detail record. If corresponding area binding information is matched, it means that this call detail record is not the first call detail record.

[0065] Further as an alternative implementation manner, the area binding database is a Redis database. The step of performing a matching query in the pre-constructed area binding database according to the first MDN information specifically includes:

[0066] Use the first MDN information as the key to perform a matching query in the area binding database to determine whether there is a key that is the same as the first MDN information. If not, output that the corresponding area binding information is not matched. If so, obtain the corresponding area binding information according to the first MDN information.

[0067] S103. When the corresponding area binding information is not matched, generate the first area binding information according to the first MDN information and the first area information, and add the first area binding information to the area binding database.

[0068] As a further optional implementation, the step of generating the first area binding information according to the first MDN information and the first area information and adding the first area binding information to the area binding database specifically includes:

[0069] A1. Use the first MDN information as the key and the first area information as the value to generate the first key-value pair representing the first area binding information;

[0070] A2. Store the first key-value pair into the area binding database.

[0071] Specifically, if the corresponding area binding information is not matched, it can be determined that the current call record is the first call record after subscribing to the product. Establish the key-value pair <MDN, Region> of the card number and area in the current call record and store it as the comparison basis for the subsequent access to the network by the current IoT card.

[0072] S104. When the corresponding area binding information is matched, determine the second area information according to the area binding information, compare the first area information and the second area information, and then perform IoT area restriction according to the comparison result.

[0073] As a further optional implementation, the step of determining the second area information according to the area binding information, comparing the first area information and the second area information, and then performing IoT area restriction according to the comparison result specifically includes:

[0074] Determine the second area information according to the value of the area binding information;

[0075] Compare the first area information and the second area information to determine whether they are consistent;

[0076] When the comparison is consistent, obtain the area restriction connection status of the current IoT card. If the area restriction connection status is in the disconnected state, restore the network connection of the IoT card;

[0077] When the comparison is inconsistent, obtain the area restriction connection status of the current IoT card. If the area restriction connection status is in the connected state, disconnect the network connection of the IoT card.

[0078] Specifically, if the corresponding area binding information is matched, it can be determined that the current call record is a non-first call record after subscribing to a product. Compare the first area information reported in the current call record with the second area information in the matched area binding information as follows:

[0079] 1) If the comparison result is consistent, obtain the area-restricted connection status of the current IoT card through the first MDN information. If the connection status is "connecting", discard it; if the connection status is "disconnecting", then assemble a PCRF / PCF restore connection message and send it to the downstream network element task execution service;

[0080] 2) If the comparison result is inconsistent, obtain the area-restricted connection status of the current IoT card through the first MDN information. If the connection status is "disconnecting", discard it; if the connection status is "connecting", then assemble a PCRF / PCF block connection message and send it to the downstream network element task execution service.

[0081] Further, as an optional implementation manner, when the comparison is consistent, the step of restoring the network connection of the IoT card is specifically as follows:

[0082] Determine the corresponding network element instance according to the first MDN information, generate a restore connection message according to the network element instance, and send the restore connection message to the network element task execution layer, so that the network element task execution layer restores the network connection of the IoT network card;

[0083] When the comparison is inconsistent, the step of restoring the network connection of the IoT card is specifically as follows:

[0084] Determine the corresponding network element instance according to the first MDN information, generate a block connection message according to the network element instance, and send the block connection message to the network element task execution layer, so that the network element task execution layer blocks the network connection of the IoT network card.

[0085] Specifically, when the network element task execution service receives a PCRF / PCF block or restore connection task, it matches the corresponding PCRF / PCF network element instance according to the card number (access number) in the current message, obtains the network element related configuration information, and generates a corresponding task instruction set according to the service type and instruction template, and sends it to the network element execution through SOAP information, so as to implement the operation of blocking or restoring the card.

[0086] The method steps of the embodiments of the present invention are described above. As Figure 2 shown is a specific process schematic diagram of an IoT area restriction management method provided by an embodiment of the present invention. The following further describes the complete process of the embodiment of the present invention in combination with Figure 2 for further explanation.

[0087] 1. The data collection service collects CHF (5G) call detail record messages pushed from the upstream system (IT billing), analyzes and extracts the message content. Obtain the servedGPSI (MDN) and nrCell fields in the CHF message. The nrCell field consists of the PLMN ID to which the cell belongs and the NR cell identifier (NCI). The NCI is 36 bits and is composed of the gNB identifier (gNB ID) and the Cell identifier (CI). Thus, the MDN (card number) and gNB ID (base station ID) information of the current call detail record can be obtained by analyzing the CHF message, and then the area where the base station is located can be obtained through the base station and area relationship table.

[0088] 2. Check whether the current IoT card has subscribed to the "first call detail record area restriction" control service. This service is pre - accepted by the customer, and no binding relationship between the card and the actual usage area is established during the acceptance process. If the current IoT card has not subscribed to this product, the process ends; otherwise, determine whether it is the first time to establish a binding relationship between the card number and the actual usage location. This can be achieved by querying the REDIS cache <FIRST_BILL_BINDING_$MDN,REGION>. The KEY value stores the IoT card number, and the value stores the actual usage area bound by the first call detail record. If it is empty or does not exist, it means that it has not been bound yet, then add or update the value to form a comparison template prototype.

[0089] 3. During the user's usage process, a large number of instant network element messages will be generated, and these messages will be pushed to the connection management platform. The <MDN,REGION_X> correspondence in the message can be obtained immediately by the same method. By comparing the matching relationship between <MDN,REGION> in the REDIS cache and <MDN,REGION_X> in the current message, determine whether the user is using within the area bound by the first call detail record. The specific operations are as follows:

[0090] Case 1: The matching result shows that the user is still using within the bound area. Obtain the area restriction connection status of the current card through the MDN. If the connection status is "connected", discard it; if the connection status is "disconnected", then assemble a PCRF / PCF restore connection message for the downstream network element task execution service;

[0091] Case 2: The matching result shows that the user is not using within the bound area. Obtain the area restriction connection status of the current card through the MDN. If the connection status is "disconnected", discard it; if the connection status is "connected", then assemble a PCRF / PCF block connection message for the downstream network element task execution service.

[0092] 4. When the network element task execution service receives the PCRF / PCF blocking or connection restoration task, it matches the corresponding PCRF / PCF network element instance according to the card number (access number) in the current message, obtains the network element related configuration information, generates the corresponding task instruction set according to the service type and instruction template, and sends it to the network element for execution through the SOAP message, so as to realize the operation of blocking or restoring the card.

[0093] It can be recognized that in the embodiment of the present invention, the area information of using the IoT card is obtained through the call detail record message reported by the user when first using the IoT, the binding relationship between the area information and the IoT card is established and stored. There is no need for the user to preset the binding relationship between the IoT card and the actual usage location in advance, which greatly simplifies the management difficulty and operation difficulty of the user's IoT devices; by collecting the call detail record messages reported by the user when using the IoT subsequently in real time to obtain the current actual usage area, and comparing the actual usage area with the stored binding relationship, the network can be automatically restored for users who meet the binding relationship, and the network can be automatically blocked for users who do not meet the binding relationship, realizing automatic IoT area restriction management, without manual operation of resuming or stopping the machine, reducing the management cost of IoT area restriction, and improving the operation and maintenance efficiency and user experience.

[0094] In addition, the present invention is different from the traditional method of restricting illegal shutdown of the area. According to the characteristics of the strong traffic demand of the IoT application, by collecting all RADUIS or CHF data packets in real time, parsing the relevant data fields to obtain the actual usage location of the device of the current call detail record and the MDN (card number), comparing the number and area binding situation in the user's first call detail record, and automatically disconnecting and restoring the network data connection means by issuing instructions to the PCRF / PCF network element in real time to achieve full-automatic area restriction control, which can automatically block and restore the network connection in real time according to the change of the actual usage location of the current card, without human intervention, avoiding the trouble of manual resuming after traditional shutdown, and further improving the operation and maintenance efficiency of the IoT.
