Description

Technical Field

[0001] This invention relates to a text message detection system and method. Specifically, this invention relates to a text message detection system and method capable of intercepting text messages and detecting their security before they are transmitted to a user device. Prior Technology

[0002] In recent years, the number of spam SMS messages (such as marketing messages and scam messages) received by users' devices has been gradually increasing, affecting the user experience of using mobile devices.

[0003] Existing SMS detection systems only analyze the content of SMS messages after the user device receives them to determine whether the message is spam. However, detecting spam SMS messages after the user device has received them cannot prevent them from being sent to the user device in the first place, and also results in low efficiency in SMS detection.

[0004] In view of this, how to provide a system and method that can intercept SMS messages before they are sent to the user's device and efficiently detect SMS messages is an urgent goal that the industry needs to strive for. Summary of the Invention

[0005] One object of the present invention is to provide a text message detection system. The text message detection system includes a user registration database and a mediation device. The user registration database stores a plurality of base station addresses corresponding to a plurality of user identification codes, and the mediation device is communicatively connected to the user registration database. The mediation device receives a first text message packet, wherein the first text message packet contains a target user identification code. Based on the target user identification code, the mediation device obtains a target base station address corresponding to the target user identification code from the user registration database. The mediation device records the target user identification code and the target base station address corresponding to the target user identification code. The mediation device receives a second text message packet, wherein the second text message packet contains the target user identification code and information to be decoded. Based on the target user identification code, the mediation device obtains the target base station address corresponding to the target user identification code. The mediation device obtains a detection result corresponding to the second text message packet.

[0006] Another object of the present invention is to provide a text message detection method for an electronic device. The method includes the following steps: the mediator receives a first text message packet, wherein the first text message packet contains a target user identification code; the mediator obtains a target base station address corresponding to the target user identification code from a local registration database based on the target user identification code; the mediator records the target user identification code and the target base station address corresponding to the target user identification code; the mediator receives a second text message packet, wherein the second text message packet contains the target user identification code and information to be decoded; the mediator obtains the target base station address corresponding to the target user identification code based on the target user identification code; and the mediator obtains a detection result corresponding to the second text message packet.

[0007] The SMS detection technology (including at least an SMS detection system and method) provided by this invention can obtain and record the target base station address corresponding to the target user identification code in the SMS after receiving it. Next, this invention can analyze the SMS and determine whether it is spam. Finally, based on the detection results, this invention further determines whether to transmit the SMS to the target base station corresponding to the target base station address. Because this invention can intercept SMS messages before they are transmitted to the user device, the SMS detection technology provided by this invention can prevent spam SMS messages from being transmitted to the user device in the first instance, thus increasing the efficiency of SMS detection.

[0008] The following detailed description of the invention and its implementation methods, in conjunction with the accompanying drawings, is intended to enable those skilled in the art to understand the technical features of the claimed invention. Simple Explanation of the Diagram

Implementation

[0010] The following will explain the SMS detection system and method provided by the present invention through embodiments. However, these embodiments are not intended to limit the implementation of the present invention to any environment, application, or manner described in these embodiments. Therefore, the description of the embodiments is for illustrative purposes only and is not intended to limit the scope of the present invention. It should be understood that in the following embodiments and drawings, elements not directly related to the present invention have been omitted and are not shown, and the dimensions of each element and the dimensional ratio between elements are only illustrative and are not intended to limit the scope of the present invention.

[0011] The SMS detection system of the first embodiment of the present invention is illustrated in Figure 1. The SMS detection system 1 includes a household registration database (HLR) and a mediation device (MED) communicatively connected to the household registration database (HLR).

[0012] For example, a modem (MED) may include a processor, a transceiver interface, and a storage device. The modem can be used to store data (e.g., SMS packets, base station addresses, etc.), or to parse and process received data and transmit the data to other devices.

[0013] It should be noted that the network system to which this invention is applied includes a Service Control Point (SCP), a standard component in telecommunications networks. This SCP includes a service program (Short Message Deliver Service, SMDS) capable of parsing the SCCP / MAP protocol, and a mediation device (MED) is a device capable of performing functions within this service.

[0014] For example, a local registry (HLR) may include a storage device and a transceiver interface. The HLR can be used to store user device data (e.g., user identification number, base station address corresponding to the user identification number, etc.). Other devices holding user identification numbers can request specific user identification number data from the HLR. In some implementations, the HLR may be implemented through a cloud database.

[0015] In this invention, the main function is to analyze the SMS message through the SMS detection system 1 to determine whether the SMS message is spam, and based on the detection result, to further determine whether to send the SMS message to the base station. The following paragraphs will describe in detail the implementation details related to this invention.

[0016] In the first embodiment, for ease of explanation, please refer to the SMS detection operation flowchart 200 in Figure 2.

[0017] First, during operation S201, the mediation device MED receives a first SMS packet, wherein the first SMS packet contains a target user identification code.

[0018] In some implementations, the sender of the first SMS packet may be an external SMS center. It should be noted that the sender transmits the first SMS packet to the SMS detection system 1 to inform the SMS detection system 1 that the sender wishes to obtain router information corresponding to the target user identifier (e.g., a target base station address corresponding to the target user identifier).

[0019] It should be noted that the first SMS packet was transmitted through the Mobile Application Part (MAP) platform in the SS7 network.

[0020] It should be noted that each user device corresponds to a unique user identification code. The user identification code (or target user identification code) can be the user device's mobile phone number, Mobile System ISDN (MSISDN), International Mobile Subscriber Identity (IMSI), or other identification codes.

[0021] Next, in operation S203, the mediation device MED obtains one of the target base station addresses corresponding to the target user identification code from the local registration database HLR based on the target user identification code.

[0022] It should be noted that the local registry database HLR stores multiple base station addresses corresponding to multiple user identification codes. The mediation device MED can search for the target base station address corresponding to the target user identification code from the base station addresses stored in the local registry database HLR.

[0023] Next, during operation S205, the mediation device MED records the target user identification code and the target base station address corresponding to the target user identification code. The mediation device MED can store the above information in its own storage.

[0024] In some embodiments, the mediation device MED can also store data through a third-party device. For clarity, please refer to the SMS detection system diagram in Figure 3.

[0025] As shown in Figure 3, the SMS detection system 3 further includes a base station database (DB), and the mediation device (MED) is connected to the base station database (DB) via communication.

[0026] It should be noted that the base station database (DB) may include a storage device and a transceiver interface. The DB can be used to store data about base stations (e.g., different base station addresses corresponding to different user identifiers). For example, other devices holding user identifiers can request the base station address corresponding to a user identifier from the DB. In some implementations, the DB may be implemented through a cloud database.

[0027] Specifically, the mediation device MED transmits the target user identification code and the target base station address corresponding to the target user identification code to the base station database DB. Then, the base station database DB records the target user identification code and the target base station address corresponding to the target user identification code (i.e., stores it in the base station database DB).

[0028] Therefore, by storing base station addresses through the base station database (DB), the modem (MED) can focus more on data analysis and transmission, thereby improving the operating efficiency of the modem.

[0029] Next, in operation S207, the mediation device MED receives a second SMS packet, which contains the target user identification code and information to be decoded. It should be noted that the information to be decoded, after decoding, is the actual text message that the sender (e.g., an external SMS center) wants to transmit.

[0030] In some embodiments, the sender of the second SMS packet may be the same as the sender of the first SMS packet. It should be noted that the second SMS packet sent by the sender is used to inform the SMS detection system 1 that the sender intends to send the second SMS packet to one of the target user devices corresponding to the target user identification code.

[0031] However, before the SMS detection system 1 transmits the second SMS packet to the target user device, the SMS detection system 1 will first analyze the second SMS packet to determine whether the second SMS packet belongs to spam such as promotional SMS or fraudulent SMS, and then decide whether to transmit the second SMS packet to the target base station to which the sender intends to send it based on the detection results.

[0032] In some embodiments, as shown in Figure 3, the SMS detection system 3 further includes a signal forwarding device TD. The signal forwarding device TD is communicatively connected to the mediation device MED and a plurality of external signal forwarding devices ETD1, ETD2, ..., ETDn, wherein the external signal forwarding devices ETD1, ETD2, ..., ETDn and the signal forwarding device TD correspond to different managers (e.g., telecommunications managers in different areas).

[0033] Specifically, the signal relay device TD receives the first SMS packet or the second SMS packet from one of the external signal relay devices ETD1, ETD2, ..., ETDn. Then, the signal relay device TD transmits the first SMS packet or the second SMS packet to the mediation device MED.

[0034] In some embodiments, each of the external signal relay devices ETD1, ETD2, ..., ETDn is communicatively connected to a plurality of external SMS centers. Specifically, the first SMS packet or the second SMS packet is generated by the external SMS center corresponding to one of the external signal relay devices ETD1, ETD2, ..., ETDn.

[0035] It should be noted that the signal forwarding device TD and the external signal forwarding devices ETD1, ETD2, ..., ETDn can be signal transfer points (STPs) used to forward SS7 signals, and the signal forwarding device TD and the external signal forwarding devices ETD1, ETD2, ..., ETDn communicate with each other through a public network with the SCCP / MAP protocol.

[0036] In some embodiments, the sequence in which external SMS centers transmit a first SMS packet or a second SMS packet to the mediation device MED is as follows: (1) Each of the external SMS centers transmits a first SMS packet or a second SMS packet to the SMS detection system of the present invention. (2) The first SMS packet or the second SMS packet is transmitted to the signal forwarding device TD in the SMS detection system via the external signal forwarding devices ETD1, ETD2, ..., ETDn corresponding to each of the external SMS centers. (3) The signal forwarding device TD transmits the first SMS packet to the mediation device MED.

[0037] Next, in operation S209, the mediation device MED obtains the target base station address corresponding to the target user identification code based on the target user identification code.

[0038] It should be noted that the mediation device MED can obtain the target base station address corresponding to the target user identification code from its own storage.

[0039] In some implementations, if the mediation device MED stores the target base station address corresponding to the target user identification code in the base station database DB, then the mediation device MED can obtain the target base station address corresponding to the target user identification code from the base station database DB.

[0040] Finally, during operation S211, the mediation device MED obtains the detection result corresponding to one of the second SMS packets.

[0041] In some implementations, as shown in Figure 3, the SMS detection system 3 further includes an SMS detection device MDD and a gateway GW. The gateway GW is communicatively connected to the mediation device MED and the SMS detection device MDD.

[0042] It should be noted that the SMS detection device MDD may include a processor, a transceiver interface, and a storage device. The SMS detection device MDD may store an SMS detection model and, through the SMS detection model, classify the content of SMS messages (e.g., determine whether the SMS message is a fraudulent SMS message).

[0043] It should be noted that the transceiver interface included in the apparatus of this system is an interface capable of receiving and transmitting data, or other interfaces capable of receiving and transmitting data that are known to those skilled in the art to which this application pertains. The transceiver interface can receive data from sources such as external devices, external web pages, external applications, etc. The processor included in the apparatus of this system can be various processing units, a central processing unit (CPU), a microprocessor, or other computing devices known to those skilled in the art to which this application pertains. The storage included in the apparatus of this system can be memory, a Universal Serial Bus (USB) disk, a hard disk, an optical disk, a USB flash drive, or any other storage medium or circuit known to those skilled in the art to which this application pertains and having the same function.

[0044] It should be noted that the category of the detection result is determined based on the detection task performed by the SMS detection device MDD. For example, if the SMS detection device MDD is used to detect whether an SMS is a scam SMS, then the detection result generated by the SMS detection device MDD can include a safe category and a non-safe category (i.e., a scam category).

[0045] In some implementations, the detection result can be categorized based on the level of probability that the SMS message is fraudulent. For example, the SMS detection device MDD can generate a risk score ranging from 0 to 1, and set different risk score thresholds (e.g., 0.1, 0.3, 0.6) to classify the detection result into different categories (e.g., no risk, low risk, medium risk, high risk). In some implementations, the safe category can be set to include only the no-risk category, while the unsafe category can be set to include low-risk, medium-risk, and high-risk categories.

[0046] Specifically, the mediation device (MED) analyzes the information to be decoded in the second SMS packet to generate decoding information. Then, the SMS detection device (MDD) analyzes the decoding information to generate a detection result corresponding to the second SMS packet. Finally, the mediation device (MED) obtains the detection result corresponding to the second SMS packet.

[0047] However, since the decoded information after being decoded by the mediation device MED is not in text format (e.g., binary code), in some embodiments, as shown in Figure 3, the SMS detection system 3 further includes a gateway GW, which can convert data of different formats (e.g., different network protocols, different encoding methods) to each other.

[0048] Specifically, the gateway (GW) analyzes the decoded information and generates text information corresponding to the decoded information to update the decoded information.

[0049] Furthermore, the SMS detection device MDD is used to analyze SMS text data to generate a detection result corresponding to one of the SMS texts, and transmits the detection result back to the mediation device MED through the gateway GW.

[0050] Accordingly, since the updated decoding information corresponds to a text type, the SMS detection device MDD can analyze the updated decoding information to generate the detection result corresponding to the second SMS packet.

[0051] In some implementations, as shown in Figure 3, the SMS detection system 3 further includes a plurality of base station MSCs corresponding to the corresponding base station addresses, and these base station MSCs are communicatively connected to the mediation device MED. The mediation device MED can transmit the second SMS packet to each user device connected to the base station MSCs through these base station MSCs.

[0052] Specifically, in response to the detection result corresponding to a security category, the mediation device MED transmits the second SMS packet to one of the target base stations MSC, wherein the target base station corresponds to the target base station address.

[0053] In addition, the target base station can transmit the second SMS packet to the target user device connected to the target base station to complete the SMS transmission task.

[0054] In some implementations, if the detection result corresponds to a non-security category, it indicates that the content of the second SMS packet may be spam such as a promotional or fraudulent SMS. The mediation device (MED) will generate a second SMS alert packet and transmit the second SMS alert packet to the target base station.

[0055] Next, the target base station can transmit a second SMS alert packet to the target user device. It should be noted that this second SMS alert packet contains an alert message to inform the user device that the SMS detection system has blocked a spam SMS message for the user device.

[0056] It should be noted that the communication between the mediation device MED and the base stations MSC, the local registration database HLR, and the signal relay device TD all transmit information through the SCCP / MAP protocol.

[0057] In some embodiments, the present invention may be implemented through further processes. For clarity, please refer to the SMS detection flowchart 400 in Figure 4 and the SMS detection flowchart 500 in Figure 5.

[0058] As shown in SMS detection flowchart 400, firstly, the mediation device MED receives a first SMS packet M1 containing a target user identification code. The mediation device MED transmits the first SMS packet M1 to the local registry database HLR to request the local registry database HLR to send back a first SMS end packet ME1, wherein the first SMS packet M1 contains the target base station address corresponding to the target user identification code.

[0059] Next, the mediation device MED transmits a first address packet N1 to a base station database DB, wherein the first address packet N1 contains the target user identification code and the target base station address corresponding to the target user identification code. The base station database DB stores the data received from the first address packet N1 from the mediation device MED, and the base station database DB sends back a first address end packet NE1 to the mediation device MED to inform the mediation device MED that the data storage task has been completed.

[0060] Finally, the mediation device MED transmits a first SMS end packet ME1 to the original sender of the first SMS packet M1 (e.g., external SMS center, external signal relay device corresponding to the external SMS center) to inform the original sender that the system has completed the task of "requesting the local registration database HLR to return the address of the target base station corresponding to the target user identification code".

[0061] As shown in SMS detection flowchart 500, firstly, the mediation device MED receives a second SMS packet M2, wherein the second SMS packet M2 contains the target user identification code and information to be decoded.

[0062] Next, the mediation device MED transmits a second address packet N2 to the base station database DB, requesting the base station database DB to return the target base station address corresponding to the target user identification code. The base station database DB transmits a second address end packet NE2 to the mediation device MED, wherein the second address end packet NE2 contains the target base station address corresponding to the target user identification code.

[0063] Next, the mediation device MED analyzes the information to be decoded in the second SMS packet M2 to generate decoding information C, and transmits the decoding information C to the gateway GW. The gateway GW analyzes the decoding information C and generates text information corresponding to the decoding information C to update the decoding information C. The gateway GW transmits the decoding information C to the SMS detection device MDD to generate a detection result R corresponding to the second SMS packet M2.

[0064] Next, the SMS detection device MDD transmits the detection result R back to the mediation device MED via the gateway GW.

[0065] Furthermore, if the detection result R corresponds to a security category, the mediation device MED will transmit the second SMS packet M2 to one of the target base stations (MSCs) corresponding to the target base station address. The target base station then transmits the second SMS packet M2 to the target user device corresponding to the target user identifier.

[0066] In some implementations, if the detection result R corresponds to a non-security category, the mediation device MED transmits a second SMS alert packet.

[0067] Finally, the target base station in the base station MSC sends back a second SMS end packet ME2 to the mediation device MED, and the mediation device MED transmits the second SMS end packet ME2 to the original sender of the second SMS packet M2 to inform the original sender that the system has completed the task of transmitting the second SMS packet M2 to the target base station corresponding to the target user identification code.

[0068] In some implementations, if the detection result R corresponds to the non-security category, the mediation device MED transmits the second SMS end packet ME2 to the original sender to inform the original sender that the system has detected that the second SMS packet M2 is a spam message and has not transmitted the second SMS packet M2 to the user device.

[0069] As described above, the SMS detection system provided by this invention can obtain and record the target base station address corresponding to the target user identification code in the received SMS. Next, this invention can analyze the SMS and determine whether it is spam. Finally, based on the detection results, this invention further decides whether to transmit the SMS to the target base station corresponding to the target base station address. Because this invention can intercept SMS before it is transmitted to the user device, the SMS detection system provided by this invention can prevent spam SMS from being transmitted to the user device in the first instance, thus increasing the efficiency of SMS detection.

[0070] A second embodiment of the present invention is a text message detection method, the flowchart of which is depicted in Figure 6. The text message detection method 600 is applicable to the text message detection system described in the first embodiment. The text message detection system includes a user registration database and a mediation device.

The text message detection method 600 performs text message detection through steps S601 to S611.

[0071] First, in step S601, the mediation device receives a first SMS packet, wherein the first SMS packet contains a target user identification code.

[0072] Next, in step S603, the mediation device obtains one of the target base station addresses corresponding to the target user identification code from the local registration database based on the target user identification code.

[0073] Next, in step S605, the mediation device records the target user identification code and the target base station address corresponding to the target user identification code.

[0074] Next, in step S607, the mediation device receives a second SMS packet, wherein the second SMS packet contains the target user identification code and information to be decoded.

[0075] Next, in step S609, the mediation device obtains the target base station address corresponding to the target user identification code based on the target user identification code.

[0076] Finally, in step S611, the mediation device obtains the detection result corresponding to one of the second SMS packets.

[0077] In some embodiments, the SMS detection system further includes a base station database, the mediation device is communicatively connected to the base station database, and recording the target user identification code and the target base station address corresponding to the target user identification code further includes the following steps: the mediation device transmits the target user identification code and the target base station address corresponding to the target user identification code to the base station database; and the base station database records the target user identification code and the target base station address corresponding to the target user identification code.

[0079] In some embodiments, the SMS detection system further includes an SMS detection device and a gateway. The gateway is communicatively connected to the mediation device and the SMS detection device, and obtaining the detection result corresponding to the second SMS packet further includes the following steps: the mediation device analyzes the information to be decoded in the second SMS packet to generate decoding information; the SMS detection device analyzes the decoding information to generate the detection result corresponding to the second SMS packet; and the mediation device obtains the detection result corresponding to the second SMS packet.

[0080] In some embodiments, analyzing the information to be decoded in the second SMS packet to generate the decoded information further includes the following steps: the gateway analyzes the decoded information and generates text information corresponding to the decoded information to update the decoded information.

[0081] In some embodiments, the SMS detection system further includes a plurality of base stations corresponding to the corresponding base station addresses, which are communicatively connected to the mediation device. The SMS detection system further performs the following steps: in response to the detection result being associated with a security category, the mediation device transmits the second SMS packet to one of the base stations as a target base station, wherein the target base station is associated with the target base station address.

[0082] In some embodiments, the SMS detection method 600 further includes the following steps: the mediation device, in response to the detection result corresponding to a non-security category, transmits a second SMS alert packet to the target base station, wherein the second SMS alert packet is generated by the mediation device.

[0083] In some embodiments, the SMS detection system further includes a signal forwarding device communicatively connected to the mediation device and a plurality of external signal forwarding devices, wherein the external signal forwarding devices and the signal forwarding device correspond to different administrators. The signal forwarding device is configured to perform the following steps: receiving the first SMS packet or the second SMS packet from one of the external signal forwarding devices; and transmitting the first SMS packet or the second SMS packet to the mediation device.

[0084] In some embodiments, the first SMS packet or the second SMS packet is generated by an external SMS center corresponding to one of the external signal relay devices.

[0085] In addition to the steps described above, the second embodiment can also perform all the operations and steps of the SMS detection system described in the first embodiment, have the same function, and achieve the same technical effect. Those skilled in the art to which this invention pertains can directly understand how the second embodiment performs these operations and steps based on the first embodiment described above, has the same function, and achieves the same technical effect, so it will not be described in detail here.
