Description

Technical Field

[0001] This application relates to the field of power communication technology, and in particular to a link quality detection system, method, apparatus, device, and storage medium. Background Technology

[0002] In power dispatching applications, many unmanned stations require the placement of communication equipment, and ensuring the smooth operation of this equipment is crucial to guarantee that each power dispatching point can receive dispatch instructions from higher authorities and report information in a timely and accurate manner. However, in reality, some power dispatching points may experience situations where their communication equipment remains unused for extended periods, necessitating periodic checks to ensure its proper functioning.

[0003] Currently, the most common method for testing the functionality of communication equipment is through manual call testing. Manual calls can only connect to one device at a time, which is inefficient, time-consuming, and prone to errors, especially in scenarios requiring testing a large number of terminal communication devices. Furthermore, existing call tests only provide a result of whether the call was successful or not; they cannot evaluate the quality of the communication link, potentially causing delays in receiving scheduling instructions due to poor link quality. Summary of the Invention

[0004] This invention provides a link quality detection system, method, apparatus, device, and storage medium, which uses a hybrid networking method to detect whether multi-terminal communication devices can be used normally and to evaluate the quality of communication links.

[0005] In a first aspect, the present invention provides a link quality detection system, comprising the following steps:

[0006] The device under test includes a terminal under test, a voice gateway, a program-controlled exchange, and a link quality testing server. The link quality testing server exchanges data with the voice gateway via Ethernet, and the voice gateway exchanges data with the program-controlled exchange and the device under test via an E1 transmission link.

[0007] The link quality detection server is used to generate detection events and send them to the terminal under test and the voice gateway. The detection event indicates that the terminal under test and the voice gateway establish a detection call through the program-controlled exchange, wherein the voice gateway is the calling device and the terminal under test is the called device.

[0008] The program-controlled exchange is used to obtain the number of the called device and the number of the calling device through the establishment of the detection call process, and obtain the target link quality detection number according to the number of the calling device, and send it to the terminal under test, wherein the target link quality detection number and the number of the calling device are corresponding;

[0009] The link quality detection server is also used to generate link quality detection instructions and send them to the voice gateway;

[0010] The voice gateway is used to generate a test tone according to the link quality detection command and send it to the terminal under test;

[0011] The terminal under test is used to obtain the attribute information of the test tone and send the attribute information of the test tone and the target link quality detection number to the link quality detection server;

[0013] Furthermore, it also includes:

[0014] Relay gateway;

[0015] The device under test includes analog devices under test and digital devices under test. The relay gateway exchanges data with the program-controlled exchange through an E1 transmission link. The relay gateway also exchanges data with the digital devices under test through Ethernet.

[0016] The relay gateway is used to obtain the test tone through the programmable switch and forward it to the digital device under test when the voice gateway generates a test tone that needs to be sent to the digital device under test.

[0017] Furthermore, it also includes:

[0018] The link quality detection server is also used to acquire the channel noise of the voice gateway and the channel noise of the terminal under test;

[0019] The link quality detection server is also used to acquire the energy of the test tone, and calculate the signal-to-noise ratio of the communication link based on the test tone energy, the channel noise of the voice gateway, and the channel noise of the terminal under test;

[0022] Furthermore, it also includes:

[0023] The terminal under test is also used to receive the target link quality detection number, generate reception information and send it to the link quality detection server;

[0024] The link quality detection server is also used to confirm whether the received information corresponds to the calling number. If the received information corresponds to the calling number, an off-hook instruction is generated and sent to the terminal under test.

[0025] The terminal under test establishes a call with the voice gateway according to the off-hook command.

[0026] Secondly, the present invention also provides a link quality detection method, applied to a link quality detection server, comprising:

[0027] A detection event is generated and sent to the terminal under test and the voice gateway. The detection event indicates that the terminal under test and the voice gateway establish a detection call through the program-controlled exchange, wherein the voice gateway is the calling device and the terminal under test is the called device.

[0030] Based on the attribute information of the test sound, a target link quality detection evaluation is generated.

[0035] The quality of the target link is evaluated based on the transmission delay and the signal-to-noise ratio of the communication link.

[0036] Furthermore, the generation of target link quality detection and evaluation includes:

[0037] Confirm whether the received information corresponds to the number of the calling device. If the received information corresponds to the number of the calling device, generate an off-hook instruction and send it to the terminal under test. The received information is generated by the terminal under test receiving the target link quality detection number and sending it to the link quality detection server. The off-hook instruction instructs the device under test to establish a call with the voice gateway.

[0038] Thirdly, the present invention also provides a link quality detection device, comprising:

[0039] The detection event generation module is used to generate detection events and send them to the terminal under test and the voice gateway.

The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0059] In current communication quality testing of power communication equipment, a separate communication device is often required to implement functional telemetry. This separate deployment not only increases testing costs but also results in low telemetry efficiency because it cannot simultaneously perform telemetry testing on multiple terminals. Based on the background information and considerations of the existing application environment, this invention aims to improve telemetry call efficiency by configuring multiple service channels to concurrently perform telemetry tasks through a hybrid networking approach that separates the voice and signaling channels on the existing voice service channels of power communication equipment.

[0060] like Figure 1As shown in the figure, this application provides a link quality detection system, including a terminal under test, a voice gateway, a program-controlled exchange, and a link quality detection server. The link quality detection server exchanges data with the voice gateway via Ethernet, and the voice gateway exchanges data with the program-controlled exchange and the device under test via E1 transmission links.

[0061] The link quality detection server is used to generate detection events and send them to the terminal under test and the voice gateway. The detection event indicates that the terminal under test and the voice gateway establish a detection call through the program-controlled exchange, wherein the voice gateway is the calling device and the terminal under test is the called device.

[0062] Specifically, the link quality detection server generates and issues instructions to the communication devices participating in telemetry, thereby driving each process step in the link quality detection process. The link quality detection server transmits instructions via Ethernet, and the voice gateway and the terminal under test receive the instructions issued by the link quality detection server directly or indirectly, and complete the corresponding actions according to the instructions.

[0063] In a specific process of establishing a testing call, the link quality testing server configures a link quality testing task, which can be set to execute immediately or on a scheduled basis. Simultaneously, the link quality testing task includes multiple call tasks. Multiple processes can be started on the link quality testing server, each process executing one call, thereby achieving concurrency of multiple calls and reducing the testing time of the task.

[0064] When the testing task is initiated, the link quality testing server sends a called party preparation command to the terminal under test. This command informs the terminal under test of the corresponding calling party number and instructs the terminal to enter the testing preparation phase. The terminal under test then initiates a device self-test based on this command and sends a self-test event to the link quality testing server. Specifically, the self-test event includes normal onboard chip testing, on-board chip testing, and also includes entering test mode via the control interface chip to test the electrical characteristics of the analog phone, such as the power supply current, standby power consumption, and transmission line length. After the terminal under test sends the self-test event, it enters the call process to be tested.

[0065] The link quality detection server also sends a calling party preparation instruction to the voice gateway. This instruction informs the voice gateway of the corresponding called number and instructs the voice gateway to initiate an off-hook response as the calling party. After the voice gateway initiates an off-hook response to the called party according to the preparation instruction, it returns an off-hook event to the link quality detection server. Upon detecting a dial tone in the off-hook event, the voice gateway again returns a dial tone detection event to the link quality detection server.

[0066] The PBX is used to obtain the number of the called device and the number of the calling device through the call establishment process, and obtain the target link quality detection number based on the number of the calling device, and send it to the terminal under test, wherein the target link quality detection number corresponds to the number of the calling device.

[0067] Specifically, all data interaction between the voice gateway and the terminal under test (TBD) must pass through a programmable switch (PBX). During the process of the voice gateway initiating a dialing to the TBD, the voice gateway sends the called number to the PBX and then returns information about the completed dialing event to the link quality detection server. After obtaining the calling number, the PBX, according to its preset configuration, changes the calling number to the target link quality detection number and, based on the received called number, sends this target link quality detection number to the TBD, initiating ringing. Subsequently, the voice gateway detects the ringing tone event of the TBD device and sends a notification of the detected ringing tone to the link quality detection server.

[0068] In a preferred example, after receiving the target link quality detection number, the terminal under test generates reception information and sends it to the link quality detection server. The link quality detection server also confirms whether the reception information corresponds to the calling number. If the reception information corresponds to the calling number, it generates an off-hook instruction and sends it to the terminal under test. The terminal under test then establishes a call with the voice gateway based on the off-hook instruction. That is, when the link quality detection server confirms that the calling number corresponds to the currently detected link, a call relationship is established between the calling device and the called device. At this time, both the calling device and the called device enter a call state. Whether or not a call state can be entered can qualitatively determine the availability of the terminal under test and create conditions for entering the subsequent link quality detection.

[0069] After the terminal under test goes off-hook and enters a call state, the link quality detection server generates a link quality detection command and sends it to the voice gateway. The voice gateway generates a test tone according to the link quality detection command and sends it to the terminal under test. The terminal under test obtains the attribute information of the test tone and sends the attribute information of the test tone and the target link quality detection number to the link quality detection server. The link quality detection server then generates a target link quality detection evaluation according to the attribute information of the test tone.

[0070] Specifically, the link quality testing server sends a DTMF number instruction to the voice gateway, which then sends a confirmation tone to the terminal under test based on the instruction. After receiving the DTMF number, the terminal under test sends the confirmation tone DTMF to the link quality testing server. If the terminal under test correctly receives the DTMF voice and can parse the DTMF number from the voice, it considers the transmission status of the link to be correct.

[0071] By utilizing the period during which no voice is transmitted, which is equivalent to sending a silence signal, the channel noise floor energy is calculated at the voice gateway and the device under test, and then sent to the target device.

[0072] In a preferred embodiment, the link quality detection server also sends a test tone command to the voice gateway, which then sends a test tone to the terminal under test according to the command. In this embodiment, the test tone is a 1kHz test tone. The terminal under test receives the test tone, calculates the energy of the received test tone, and sends the calculation result to the link quality detection server. Since the amplitude of the initial test tone is known, the link quality detection server can quantitatively evaluate the current link transmission quality by calculating the difference between the received test tone energy and the initial test tone energy. A lower energy loss indicates higher link transmission quality.

[0073] In a preferred example, the link quality testing server also sends a latency test command to the voice gateway. The voice gateway sends a latency test tone to the terminal under test, records the transmission time, and reports this transmission time event back to the server. After receiving the latency test tone, the terminal under test returns a specific response tone to the voice gateway. When the voice gateway receives the response tone, it records the reception time of the response tone and reports this reception time event back to the server. By calculating the difference between the transmission time and the reception time, the link quality testing server obtains the total latency of the latency test tone in the link. Based on the total link latency, the quality of the link can be quantitatively evaluated; the shorter the total link latency, the higher the transmission quality of the link.

[0074] In another example, link latency testing can be achieved as follows: A link quality testing server sends a loopback command to the terminal under test (DUT); the DUT performs a remote loopback; after receiving a successful loopback message from the DUT, the link quality testing server sends a DTMF tone playback command to the voice gateway; the voice gateway receives the loopback command from the link quality testing server, sends the DTMF tone to the DUT, and records the transmission timestamp; the voice gateway then receives the DTMF tone returned from the DUT and records the reception timestamp; the voice gateway feeds back the transmission and reception timestamps to the link quality testing server; the link quality testing server calculates the transmit / receive time difference, and then calculates the DTMF tone detection time based on existing DTMF detection algorithms. Half of the transmit / receive time difference and the DTMF detection time difference can be considered a relatively accurate representation of the link transmission latency.

[0075] In a preferred example, the link transmission quality can also be quantitatively evaluated by calculating the link's signal-to-noise ratio (SNR). During periods when the voice gateway is not sending test audio, this can be considered as the voice gateway sending silence to the terminal under test (DUT). The voice gateway acquires the voice gateway channel noise floor A, and the DUT acquires the DUT channel noise floor B, and sends both to the link quality detection server. During periods when the voice gateway sends test audio, the voice gateway acquires the voice gateway test audio energy A, and the DUT acquires the DUT test audio energy B, and sends both to the link quality detection server. Since the amplitude of the transmitted test audio is known, subtracting the transmitted test audio energy from the voice gateway's test audio energy A and the DUT's test audio energy B yields the channel noise during the test audio transmission process, i.e., the voice gateway channel noise A and the DUT channel noise B. By performing arithmetic mean calculations on the voice gateway channel noise floor A and the DUT channel noise floor B, and on the voice gateway channel noise A and the DUT channel noise B, the noise in the application environment can be obtained. Based on the known test sound energy and the calculated noise in the application environment, the signal-to-noise ratio (SNR) can be calculated using the formula SNR = 10log(signal power / noise power), thus allowing for a quantitative assessment of the communication channel quality.

[0076] In a preferred embodiment, link quality testing can be performed not only on analog terminals under test, but also on digital terminals under test; link quality testing can be performed not only on a single device, but also on multiple devices.

[0077] Specifically, such as Figure 1 As shown in the embodiment of this application, the link quality testing system further includes a relay gateway. The device under test includes analog devices under test and digital devices under test. The relay gateway exchanges data with the program-controlled exchange through an E1 transmission link. The relay gateway also exchanges data with the digital devices under test through Ethernet. When the voice gateway generates a test tone that needs to be sent to the digital devices under test, the relay gateway obtains the test tone through the program-controlled exchange and forwards it to the digital devices under test.

[0078] Digital devices under test (DUTs) include two types of terminals: one exchanges data with a voice gateway via an integrated data transmission network, and the other exchanges data with a voice gateway via Ethernet. Power communication systems often involve multiple types of DUTs and multiple communication networks. If the DUT is directly connected to a PBX (Publicly Controlled Exchange), the PBX can directly initiate the call to the called party during the establishment of communication between the caller and the called party. If the DUT is not directly connected to the PBX, it is connected to the PBX directly connected to the DUT through a trunk gateway before initiating the call.

[0079] Specifically, the link quality testing task for multiple terminals includes multiple call tasks. The terminals under test may be analog terminals, digital terminals exchanging data with the integrated data transmission network via an E1 link to the voice gateway, and digital terminals exchanging data with the voice gateway via Ethernet. When the link quality testing server initiates a link quality testing task for the aforementioned terminals, it can start multiple processes, each executing one call, thus achieving concurrency of multiple calls. After establishing a call between the voice gateway and the terminal under test, the required test data is obtained. Then, by simply changing the two parties sending and receiving the test tones, the quality of the next communication link can be tested. Simultaneously, because the caller ID sent to the terminal under test is replaced with a specified link quality testing number through a program-controlled exchange, and the specified link quality testing number is uniformly displayed on the device under test, this solves the problem in existing solutions where the called terminal displays different caller IDs depending on the calling device, causing inconvenience for the testing at the terminal under test.

[0080] When the link quality test is completed, the test call ends. Specifically, the link quality test server sends a hang-up command to the voice gateway, and the voice gateway receives the command and hangs up. At the same time, the link quality test server sends a hang-up command to the terminal under test, and the terminal under test receives the command and hangs up.

[0081] This application embodiment improves telemetry call efficiency by setting up a link quality detection server and configuring multiple service channels to concurrently perform link quality detection tasks in a way that separates voice and signaling channels. Simultaneously, the link quality detection server can calculate and verify multiple steps in the link quality detection process, ensuring the accuracy and reliability of the link quality detection. Furthermore, the link quality detection task is no longer limited to qualitatively testing whether the communication equipment is functioning properly; it also quantitatively calculates link communication quality and generates a target link quality evaluation by calculating relevant attribute information during test tone transmission and reception. Additionally, the hybrid networking mode of EI link and Ethernet allows the tested terminal to perform link quality detection on digital terminals not limited to existing analog terminals, but also via Ethernet or a comprehensive data transmission network.

[0082] This application also provides a link quality detection method, such as... Figure 2 As shown, the method applied to the link quality detection server includes the following steps:

[0083] S201: Generate a detection event and send it to the terminal under test and the voice gateway. The detection event indicates that the terminal under test and the voice gateway establish a detection call through the program-controlled exchange, wherein the voice gateway is the calling device and the terminal under test is the called device.

[0084] S202: Generate a link quality detection command and send it to the voice gateway, wherein the voice gateway is used to generate a test tone according to the link quality detection command and send it to the terminal under test.

[0085] S203: Obtain the attribute information of the test tone returned by the terminal under test and the target link quality detection number, wherein the target link quality detection number is obtained by the program-controlled exchange through the process of establishing a test call, obtaining the number of the called device and the number of the calling device, and obtaining the target link quality detection number based on the number of the calling device, and sending it to the terminal under test for acquisition.

[0086] S204: Generate a target link quality detection evaluation based on the attribute information of the test sound.

[0087] In a preferred example, generating a target link quality assessment includes:

[0088] Obtain the channel noise of the voice gateway and the channel noise of the terminal under test;

[0089] The energy of the test tone is obtained, and the signal-to-noise ratio of the communication link is calculated based on the test tone energy, the channel noise of the voice gateway, and the channel noise of the terminal under test.

[0090] The test tone transmission time of the voice gateway and the test tone reception time of the terminal under test are obtained, and the communication link transmission delay is obtained based on the test tone transmission time and the test tone reception time.

[0091] The quality of the target link is evaluated based on the transmission delay and the signal-to-noise ratio of the communication link.

[0092] In a preferred example, generating a target link quality assessment includes:

[0093] Confirm whether the received information corresponds to the number of the calling device. If the received information corresponds to the number of the calling device, generate an off-hook instruction and send it to the terminal under test. The received information is generated by the terminal under test receiving the target link quality detection number and sending it to the link quality detection server. The off-hook instruction instructs the device under test to establish a call with the voice gateway.

[0094] This application embodiment also provides a link quality detection device 300, such as... Figure 3 As shown, it includes:

[0095] The detection event generation module 301 is used to generate a detection event and send it to the terminal under test and the voice gateway. The detection event indicates that the terminal under test and the voice gateway establish a detection call through the program-controlled exchange, wherein the voice gateway is the calling device and the terminal under test is the called device.

[0096] The link quality detection instruction generation module 302 is used to generate a link quality detection instruction and send it to the voice gateway, wherein the voice gateway is used to generate a test tone according to the link quality detection instruction and send it to the terminal under test;

[0097] The detection data acquisition module 303 is used to acquire the attribute information of the test tone returned by the terminal under test and the target link quality detection number. The target link quality detection number is obtained by the program-controlled exchange through the process of establishing a detection call, which obtains the number of the called device and the number of the calling device, and obtains the target link quality detection number based on the number of the calling device, and sends it to the terminal under test for acquisition.

[0098] The link quality evaluation generation module 304 is used to generate a target link quality detection evaluation based on the attribute information of the test sound.
