Description

Technical Field

[0001] The present invention relates to the field of power communication technology, and in particular to a method, device, system, equipment and medium for detecting faults in a communication link. Background Art

[0002] With the continuous development of the information society, communication systems have also undergone tremendous changes, and people's requirements for communication quality are becoming increasingly higher. A communication link refers to the complete path for end-to-end transmission of voice or data signals in a communication system. A link failure occurs when any link in the communication path fails, resulting in a degradation of end-to-end communication quality or even a complete interruption. The stability of communication links directly affects social production and daily life, and a failure can lead to immeasurable losses.

[0003] Existing communication equipment detection methods can only rely on manual inspection of the line section by section. This method is time-consuming, inefficient, and cannot provide timely repairs. In addition, due to the subjectivity and technical limitations of manual inspection, it is impossible to accurately locate link faults, making it difficult to formulate reasonable maintenance strategies.

[0004] It can be seen that how to effectively troubleshoot communication links and maintain the stability of power communication systems has become a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

[0044] In the description of this application, it should be noted that, unless otherwise defined, all technical and scientific terms used in this application have the same meanings as those commonly understood by those skilled in the art. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Those skilled in the art will understand the specific meanings of the above terms in this application in specific circumstances.

[0045] In existing communication link fault detection processes, the connection status, voice quality, and internal device status of the terminal device under test can often only be detected when a call is connected. However, if a call cannot be completed, the link fault point cannot be located. Furthermore, in circuit-switched communication networks, the lack of intelligent transformation of individual digital trunk boards prevents effective identification of subsequent link status.

[0046] Based on this, an embodiment of the present invention provides a method for detecting a communication link failure. For details, see Figure 1 , Figure 1 The figure shows a flow chart of a method for detecting a fault in a communication link according to one embodiment of the present invention, which includes the following steps:

[0047] S1. Receive a call signal initiated by a server to detect a communication link and send it to the terminal device under test.

[0048] It should be understood that in a typical communication link architecture, the server is responsible for initiating the call, known as the calling party. Signaling is processed by modules such as the relay board and user board, and the call is sent to a dedicated terminal (the terminal device under test described below). The dedicated terminal then responds to the call (known as the called party), transmits the corresponding device information back to the server as the test target, and thus draws a link diagram of each node to indicate information such as the fault location.

[0049] In this embodiment, the cascaded relay devices at each level will receive the detection call signaling initiated by the server and perform signaling penetration and transmission operations. Specifically, each relay device will sequentially parse and convert the received call signal and then transmit it to the terminal device under test. During this process, the path node information formed during the call process will be recorded. It is worth noting that the calling number of the call initiating the call on the server can be individually configured.

[0050] For example, in some embodiments of the present invention, if the relay device includes an intelligent relay board and a non-intelligent relay board, the intelligent relay board will record the path information, which will be used to generate a subsequent link diagram, while the non-intelligent relay board will directly transmit the signaling to the next node.

[0051] S2. Receive the device information containing the UID identifier returned by the terminal device under test after answering the call signal, and synchronously generate path node information.

[0052] After the call signal is transmitted to the terminal device under test, it responds and transmits device information, including a network-wide unique UID, back to the server via the voice link. During this process, this device information is first received by a relay device and then forwarded to the server. The UID identifier identifies each terminal device, and the path node information includes information about the relay nodes passed through.

[0053] It's worth noting that a unified link quality test number will be used on the tested terminal device, making it easier to identify it. It should be understood that the traditional caller number displayed on the called terminal device varies depending on the server calling, which reduces the convenience of the customer checking the tested device. This embodiment replaces the caller's originating call number, allowing the called terminal to uniformly display the designated link quality test number, making it easier for the customer to understand the test status of the tested device.

[0054] S3. When a hang-up signal sent by the terminal device under test is detected, the hang-up delay is triggered, and the device information is sent to the server first.

[0055] During the device information transmission process, in order to ensure that the UID identification and test number are sent completely, the relay device will delay the transmission of the hang-up signal within a preset time after receiving the hang-up signaling of the terminal device under test. For example, a hang-up delay of 200ms+15ms is started. That is, within this delay, the relay device will temporarily suspend sending the hang-up signal of the terminal device under test, but give priority to processing data reporting. That is, the UID identification information, test number and other information are first transmitted back to the server, and when it is confirmed that these device information has been successfully sent to the server, the hang-up signal is sent to the server. The cascaded relay devices at all levels need to perform the above-mentioned hang-up and return operation steps of this embodiment in sequence until the last relay device on the signal link is completed.

[0056] As you can understand, in this embodiment, the active communication period is from the time the tested terminal device answers until it hangs up. During this period, the relay device only transparently transmits the voice stream and does not trigger any interception action. Regardless of how long the call lasts after the tested terminal device answers (30 seconds or 30 minutes), interception is only triggered when the tested terminal device "hangs up" and has no direct timing relationship with the answering action. This design avoids interfering with normal communication while accurately capturing key status information before the link is released.

[0057] Further, S4, a communication node link graph is generated according to the path node information.

[0058] It should be understood that in this embodiment, the communication node link diagram exists in the form of a topology diagram. The relationship between relay devices and the topology diagram is essentially a mapping between physical devices and the network's logical structure. Together, they constitute a visual operation and maintenance system for the communication network. For example, each intelligent relay board will exist as a unique node in the topology diagram, while non-intelligent relay boards will be marked as dotted nodes in the topology diagram.

[0059] Based on this, during the call process of this embodiment, data (UID identification, timestamp, etc.) is reported every time a smart relay board is passed through, and a path sequence is generated with these reported data, and the above-mentioned path node information is generated with these sequences, and a visual link topology diagram is constructed with these node information.

[0060] S5. Reversely detect calls step by step and locate link faults using the communication node link diagram.

[0061] On the server, based on the device information with the unique UID identifier of the entire network and the detection number (ie, test number) of the relevant program-controlled switch received in sequence, a communication node link connection diagram from the server to the terminal device under test can be drawn and stored.

[0062] If the terminal device under test detects that a call is unresponsive, a call is made from the reverse end using the test number in the device information. Specifically, the server generates a reverse test queue based on the link map, initiates a reverse test from the end node, and locates the communication link fault within the communication node link map based on the call results. Specifically, the call number is the test number of the programmable switch reported by each relay node. By calling with this test number, the faulty node is located.

[0063] In summary, this embodiment initiates a detection call through the call server, and the intelligent relay board dynamically parses and forwards the signaling. After the terminal device responds, it returns a unique UID identifier through the voice channel. At the same time, the intelligent relay board signaling delay control is used to realize priority reporting of data before hanging up, and the network-wide unique UID and test number are transmitted on the voice channel. At the same time, combined with the dotted path mark of the non-intelligent relay device, an accurate communication node link topology map is generated, and when the communication is abnormal, the reverse step-by-step call mechanism is triggered to quickly and accurately locate the faulty node, thereby improving the efficiency of communication link detection.

[0064] An embodiment of the present invention provides a communication link fault detection device. For details, see Figure 2 , Figure 2The figure shows a schematic diagram of a communication link fault detection device according to one embodiment of the present invention. The device includes a call server, a program-controlled switch, and a dedicated terminal device (i.e., the target terminal device under test in this embodiment). The dedicated terminal device, as the end node of the communication link, receives and responds to test calls from the call server, fulfilling the dual roles of UID return and link quality feedback.

[0065] The program-controlled exchange includes several intelligent relay devices and non-intelligent relay devices, which are used to parse the call signaling sent by the call server and send it to the target terminal device.

[0066] from Figure 2 As can be seen, the program-controlled switches in this embodiment are configured in two groups. The group of program-controlled switches near the call server includes intelligent relay boards A and B and a non-intelligent relay board F. The group of program-controlled switches near dedicated terminal devices E and I is configured with two intelligent relay boards C and G and two user boards D and H. Relay boards C and G are connected to user boards D and H, respectively. It should be understood that the user board is the core module that connects to the user terminal device and is responsible for implementing the physical interface and signal processing between the user line and the switch.

[0067] For example, the intelligent relay boards provided in this embodiment are the digital relay boards A and B after intelligent transformation. They are mixed with the non-intelligent digital relay board F, such as the IP-type digital relay board, to form a network. All links between the two intelligently transformed digital relay boards are regarded as the same link, and the detection results are not affected.

[0068] Correspondingly, the target terminal device is used to return the UID identification information to the call server after answering the call signaling. The call server is used to draw and send the call signaling, and generate a communication node link diagram with the fault marked based on the received UID identification information. Example:

[0069] The link connection diagram generated by the dedicated terminal device E is: server-ABCD-dedicated terminal device E, and the link connection diagram through the dedicated terminal device I is: server-AGH-dedicated terminal device I.

[0070] When each intelligent relay device detects the on-hook instruction sent by the target terminal device, it executes the operations of on-hook delay and UID identification information return in sequence.

[0071] like Figure 2 As shown, when the intelligent relay device is in the relay state, the test number generated by the program-controlled switch is reported to the call server.

[0072] Another embodiment of the present invention provides a communication link fault detection system. For details, see Figure 3 , Figure 3 The figure shows a schematic diagram of the structure of a communication link fault detection system in one embodiment of the present invention, including:

[0073] The calling module M1 is used to receive the calling signal initiated by the server for detecting the communication link and send it to the terminal device under test;

[0074] The answering module M2 is used to receive the device information including the UID identifier returned by the terminal device under test after answering the call signal, and synchronously generate the path node information;

[0075] The delay module M3 is configured to trigger an on-hook delay upon detecting an on-hook signal sent by the terminal device under test, and preferentially send the device information to the server;

[0076] A link graph generating module M4 is configured to generate a communication node link graph based on the path node information;

[0077] The fault location module M5 is used to detect calls in reverse step by step and locate link faults based on the communication node link graph.

[0078] like Figure 4 As shown, an embodiment of the present invention further provides a computer device, Figure 4 This is a structural block diagram of a preferred embodiment of a computer device provided by the present invention, wherein the computer device includes a processor, a memory, and a computer program stored in the memory and configured to be executed by the processor, and the processor implements the above-mentioned method when executing the computer program.

[0079] Preferably, the computer program can be divided into one or more modules / units (e.g., computer program 1, computer program 2, ...), which are stored in the memory and executed by the processor to implement the present invention. The one or more modules / units can be a series of computer program instruction segments capable of implementing specific functions, and the instruction segments are used to describe the execution process of the computer program in the computer device.

[0080] The processor can be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor, or the processor can be any conventional processor. The processor is the control center of the terminal device, and uses various interfaces and lines to connect the various parts of the terminal device.

[0081] The memory mainly includes a program storage area and a data storage area, wherein the program storage area can store an operating system, an application program required for at least one function, etc., and the data storage area can store related data, etc. In addition, the memory can be a high-speed random access memory, or a non-volatile memory, such as a plug-in hard disk, a smart memory card (SmartMedia Card, SMC), a secure digital (Secure Digital, SD) card, and a flash card, etc., or the memory can also be other volatile solid-state storage devices.

[0082] It should be noted that the above terminal device may include, but is not limited to, a processor and a memory. Those skilled in the art will understand that Figure 4 The structural block diagram is only an example of a terminal device and does not constitute a limitation of the terminal device. It may include more or fewer components than shown in the figure, or a combination of certain components, or different components.
