Description

Technical Field

[0001] This invention relates to the field of communication network technology, and in particular to a method, apparatus, device, and medium for optimizing the performance of time synchronization networks. Background Technology

[0002] Wireless networks are constantly evolving to support higher speeds, wider coverage, improved spectrum efficiency, and support for more new services, requiring each base station to have high-precision synchronization information. For example, the basic time synchronization requirement for 5G base stations is ±1.5µs. The performance quality of the synchronization network directly impacts the performance of the wireless network and, consequently, the operator's revenue.

[0003] The constantly changing network packet latency jitter (PDV), asymmetry, and network environment factors such as traffic can affect synchronization quality, requiring continuous monitoring. However, performance monitoring of the synchronization network is a challenge for synchronization network management and maintenance. In particular, the transmission equipment that carries the time-frequency synchronization signal lacks a standard reference signal, making it impossible to measure the absolute performance of the received time-frequency signal. Currently, operators can only use expensive instruments to monitor the time synchronization network performance of network equipment on demand. This not only fails to achieve real-time monitoring and timely detection of problems in the synchronization network, but also consumes a lot of manpower and resources.

[0004] Therefore, in recent years, synchronization probe devices have emerged. These probe devices are connected to the devices to be monitored via a side-mounted connection. The probe devices themselves are equipped with GNSS satellite receiving antennas. By locking onto GNSS as a reference, they monitor and measure the performance of time signals such as 1588v2 output by the monitored devices online and report the performance data to the backend probe network management system. This enables online monitoring and timely detection of synchronization network performance problems, preventing impact on service quality.

[0005] The probe device monitors the synchronization output performance of the synchronization network devices and reports the performance data to the backend probe network management system. When the device's time synchronization network performance deteriorates, an alarm can be generated on the synchronization network probe monitoring system, thus prompting maintenance personnel to perform fault repair. However, the following problems exist:

[0006] (1) Before the maintenance personnel complete the fault repair, the time synchronization network performance of the synchronization network equipment will continue to have problems, which will affect the service performance of the communication network during this period;

[0007] (2) The probe network management system can only manage the relevant data of the probe device, while the monitored synchronization network is managed by the transmission bearer control system. These two network management systems are independent and have no interface with each other. The probe network management system does not have the topology, configuration and other relevant data of the synchronization network. Therefore, when the probe device reports a problem with the performance of the time synchronization network, the operation and maintenance personnel can only manually analyze the root cause of the fault. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the prior art by proposing a method, apparatus, device and medium for optimizing the performance of a time synchronization network. This method can automatically optimize and improve the accuracy of the time synchronization network performance after the time synchronization network performance of the synchronization network equipment deteriorates, before the maintenance personnel complete the fault repair, thereby realizing the automation and reliability of the fault root cause location process of the synchronization network.

[0009] In a first aspect, the present invention provides a method for optimizing the performance of a time synchronization network, which is applied to a synchronization network probe monitoring system. The method includes the following steps:

[0010] S1: The probe device measures and obtains the time synchronization network performance of the access device and determines whether the time synchronization network performance has deteriorated. When the time synchronization network performance deteriorates, the probe device reports the time synchronization network performance deterioration fault information to the probe network management device and proceeds to step S2. When the time synchronization network performance does not deteriorate, proceeds to step S5.

[0011] S2: The probe network management device identifies the fault location based on the time synchronization network performance degradation fault information;

[0012] S3: The probe network management device prompts the maintenance personnel to carry out fault repair at the fault location and issues the first switching command to the probe device. The probe device switches from measurement mode to time source mode according to the first switching command.

[0013] The measurement mode is that the probe device measures the input time signal based on the standard Global Navigation Satellite System (GNSS) signal; the time source mode is that the probe device itself acts as a time source, tracks the standard GNSS signal, and outputs a standard time signal to the access device.

[0014] S4: The probe network management device receives the fault resolution report and then sends a second switching instruction to the probe device. The probe device switches from time source mode to measurement mode according to the second switching instruction. The fault resolution report is the report sent to the probe network management device by the maintenance personnel after they have repaired and resolved the fault location.

[0015] S5: The probe device continues to measure and acquire the time synchronization network performance of the access device, repeating steps S1 to S5 to complete the optimization of the time synchronization network performance.

[0016] Further, in step S2, the probe network management device identifies the fault based on the time synchronization network performance degradation fault information to obtain the fault location, specifically including the following steps:

[0017] S21: Set an analysis time window;

[0018] S22: Within the set analysis time window, if the probe network management device receives only one time synchronization network performance degradation fault information from a single probe device, then the synchronization network device monitored by the single probe device is identified as the fault location; if the probe network management device receives time synchronization network performance degradation fault information from multiple probe devices, then the probe network management device reports the IDs of the synchronization network devices monitored by the multiple probe devices to the transmission bearer management and control platform, and proceeds to step S23;

[0019] S23: Receive the upstream synchronization network device ID sent by the transmission bearer management and control platform; the upstream synchronization network device is the upstream time synchronization network device that the transmission bearer management and control platform finds by querying the time path tracked by the time synchronization network device whose time synchronization network performance has deteriorated after receiving the synchronization network device ID whose time synchronization network performance has deteriorated.

[0020] S24: The probe network management device identifies the fault location as the upstream synchronization network device or its upstream link, thereby obtaining the fault location.

[0021] Furthermore, after step S25, the method further includes the following step:

[0022] Based on the fault location, the probe network management device searches for the corresponding fault type and the corresponding handling method in the preset policy library, generates a work order, and dispatches it to the maintenance personnel so that the maintenance personnel can quickly handle the fault.

[0023] Furthermore, in step S1, determining whether the time synchronization network performance has deteriorated specifically includes:

[0024] The system compares the absolute value of the time deviation in the time synchronization network performance to see if it exceeds the set time deviation limit. If the absolute value of the time deviation in the time synchronization network performance does not exceed the set time deviation limit, it is determined that the time synchronization network performance has not deteriorated. If the absolute value of the time deviation in the time synchronization network performance exceeds the set time deviation limit, it is determined that the time synchronization network performance has deteriorated.

[0025] Secondly, the present invention provides a device for optimizing the performance of a time synchronization network. This device is applied to a synchronization network probe monitoring system and includes multiple probe devices and a probe network management device.

[0026] The probe device includes:

[0027] The first acquisition unit is used to measure and acquire the time synchronization network performance of the access device.

[0028] The first judgment unit, connected to the first acquisition unit, is used to determine whether the performance of the time synchronization network has deteriorated.

[0029] The first transmission unit, connected to the first judgment unit, is used to report the time synchronization network performance degradation fault information to the probe network management device when the time synchronization network performance deteriorates.

[0030] The switching unit is used to switch between measurement mode and time source mode;

[0031] The measurement mode is that the probe device measures the input time signal based on the standard Global Navigation Satellite System (GNSS) signal; the time source mode is that the probe device itself acts as a time source, tracks the standard GNSS signal, and outputs a standard time signal to the access device.

[0032] The probe network management equipment includes:

[0033] The identification unit is used to identify faults based on time synchronization network performance degradation fault information and obtain the fault location.

[0034] The second transmission unit, connected to the identification unit, is used to send a first switching instruction to the switching unit based on the time synchronization network performance degradation fault information, and the switching unit switches from measurement mode to time source mode according to the first switching instruction. The second transmission unit sends a second switching instruction to the switching unit based on the fault resolution receipt, and the switching unit switches from time source mode to measurement mode according to the second switching instruction.

[0035] Furthermore, the identification unit includes:

[0036] The settings module is used to set an analysis time window;

[0037] The receiving module is used to receive fault information about the time synchronization network performance degradation of the probe device;

[0038] The identification module is connected to both the setting module and the receiving module, and is used to identify the fault location within a set analysis time window. The specific steps for the identification module to identify the fault location are as follows:

[0039] Within the set analysis time window, if the receiving module receives time synchronization network performance degradation fault information from only one probe device, the identification module identifies the synchronization network device monitored by that single probe device as the fault location. If the receiving module receives time synchronization network performance degradation fault information from multiple probe devices, the receiving module reports the IDs of the synchronization network devices monitored by the multiple probe devices to the transmission bearer management and control platform, and receives the ID of the upstream synchronization network device sent by the transmission bearer management and control platform. Then, the identification module identifies the fault location as the upstream synchronization network device or its upstream link. Wherein: the upstream synchronization network device is the upstream time synchronization network performance degradation device found by the transmission bearer management and control platform after receiving the ID of the time synchronization network device with degraded performance, querying the time path tracked by the time synchronization network device with degraded performance, and following the time tracking path.

[0040] Furthermore, the probe network management device also includes a preset unit, which is connected to the identification unit. The preset unit is used to search for the corresponding fault type and the corresponding handling method from the preset policy library according to the fault location, generate a work order and dispatch it to the operation and maintenance personnel so that the operation and maintenance personnel can quickly handle the fault.

[0041] Furthermore, the first determination unit includes:

[0042] The first setting module is used to set the time deviation limit;

[0043] The first calculation module is used to calculate the absolute value of the time deviation in the performance of the time synchronization network;

[0044] The first comparison module is connected to the first setting module and the first calculation module respectively, and is used to compare the absolute value of the time deviation in the time synchronization network performance with the set time deviation limit.

[0045] The first determination module, connected to the first comparison module, is used to determine whether the time synchronization network performance has deteriorated based on the comparison result of the first comparison module. If the absolute value of the time deviation in the time synchronization network performance does not exceed the set time deviation limit, it is determined that the time synchronization network performance has not deteriorated. If the absolute value of the time deviation in the time synchronization network performance exceeds the set time deviation limit, it is determined that the time synchronization network performance has deteriorated.

[0046] Thirdly, the present invention provides an electronic device including a memory and a processor, wherein the memory stores a computer program, and when the processor runs the computer program stored in the memory, the processor executes the above-described method for optimizing the performance of the time synchronization network.

[0047] Fourthly, the present invention provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the above-described method for optimizing the performance of a time synchronization network.

[0048] The beneficial effects of this invention are:

[0049] 1. Because the method of the present invention enables the probe device to switch between measurement mode and time source mode (after the time synchronization network performance of the synchronization network device deteriorates and before the maintenance personnel complete the fault repair, the probe device automatically switches from measurement mode to time source mode, and the probe device itself acts as a time source, tracks standard GNSS signals, and outputs standard time signals to the access device; after the fault is resolved, the probe device automatically switches from time source mode to measurement mode), thereby automatically optimizing and improving the accuracy of the network's time synchronization network performance, and realizing the automation and reliability of the synchronization network fault root cause location process.

[0063] It is understood that the units and modules involved in the embodiments of the present invention can be implemented by software or by hardware. For example, the units and modules can be located in a processor.

[0064] Example 1:

[0065] like Figure 1 and Figure 3 As shown, this embodiment provides a method for optimizing the performance of a time synchronization network applied to a synchronization network probe monitoring system. This method can automatically optimize and improve the accuracy of the time synchronization network performance after the performance of the synchronization network equipment deteriorates, before maintenance personnel complete fault repair. This automates and improves the reliability of the synchronization network fault root cause localization process. The method specifically includes the following steps:

[0066] S1: The probe device measures and obtains the time synchronization network performance of the access device and determines whether the time synchronization network performance has deteriorated. When the time synchronization network performance deteriorates, the probe device reports the time synchronization network performance deterioration fault information to the probe network management device and proceeds to step S2. When the time synchronization network performance does not deteriorate, proceeds to step S5.

[0067] Specifically, the process of determining whether the time synchronization network performance has deteriorated is as follows:

[0068] The system compares the absolute value of the time deviation in the time synchronization network performance to see if it exceeds the set time deviation limit. If the absolute value of the time deviation in the time synchronization network performance does not exceed the set time deviation limit, it is determined that the time synchronization network performance has not deteriorated. If the absolute value of the time deviation in the time synchronization network performance exceeds the set time deviation limit, it is determined that the time synchronization network performance has deteriorated.

[0069] S2: The probe network management device identifies the fault location based on the time synchronization network performance degradation fault information;

[0070] Specifically, in step S2, the probe network management device identifies the fault based on the time synchronization network performance degradation fault information to determine the fault location, which includes the following steps:

[0071] S21: Set an analysis time window;

[0072] S22: Within the set analysis time window, if the probe network management device receives only one time synchronization network performance degradation fault information from a single probe device, then the synchronization network device monitored by the single probe device is identified as the fault location; if the probe network management device receives time synchronization network performance degradation fault information from multiple probe devices, then the probe network management device reports the IDs of the synchronization network devices monitored by the multiple probe devices to the transmission bearer management and control platform, and proceeds to step S23;

[0073] S23: Receive the upstream synchronization network device ID sent by the transmission bearer management and control platform; the upstream synchronization network device is the upstream time synchronization network device that the transmission bearer management and control platform finds by querying the time path tracked by the time synchronization network device whose time synchronization network performance has deteriorated after receiving the synchronization network device ID whose time synchronization network performance has deteriorated.

[0074] S24: The probe network management device identifies the fault location as the upstream synchronization network device or its upstream link, thereby obtaining the fault location.

[0075] S3: The probe network management device prompts the maintenance personnel to carry out fault repair at the fault location and issues the first switching command to the probe device. The probe device switches from measurement mode to time source mode according to the first switching command.

[0076] To enable maintenance personnel to quickly handle faults, the probe network management device can also look up the corresponding fault type and the corresponding handling method from the preset policy library based on the fault location, and generate a work order based on the fault type and handling method and dispatch it to the maintenance personnel.

[0077] The measurement mode is that the probe device measures the input time signal based on the standard Global Navigation Satellite System (GNSS) signal; the time source mode is that the probe device itself acts as a time source, tracks the standard GNSS signal, and outputs a standard time signal to the access device.

[0078] Since the probe device itself has a GNSS satellite receiving antenna, it is capable of providing a standard time signal. Therefore, this invention adds a mode switching module to the probe device. The modes are divided into measurement mode and time source mode. Measurement mode is the probe's original function, which is to measure the input time signal based on the standard GNSS signal. Time source mode allows the probe itself to act as a time source, tracking the standard GNSS signal and outputting a standard time signal. When the probe network management system locates a fault, it automatically sends a command to the probe device to switch it from measurement mode to time source mode.

[0079] S4: The probe network management device receives the fault resolution report and then sends a second switching command to the probe device. The probe device switches from time source mode to measurement mode according to the second switching command. The fault resolution report is the report sent to the probe network management device by the maintenance personnel after they have repaired and resolved the fault location.

[0080] S5: The probe device continues to measure and acquire the time synchronization network performance of the access device, repeating steps S1 to S5 to complete the optimization of the time synchronization network performance.

[0081] Specifically, such as Figure 2 As shown, for example, the performance of the synchronization link between aggregation device B and access device C deteriorates, causing the time synchronization network performance of access device C and access device D to exceed its limits. Specifically, this includes the following steps:

[0082] Step 1①, for Figure 2 Probe devices Y and Z measured that the time synchronization network performance of C and D exceeded the limit, and probes Y and Z reported the limit exceeded alarm to the probe network management system.

[0083] Step 2: When the probe network management receives the over-limit alarms reported by Y and Z, it reports the monitored C and D device IDs to the transmission bearer management and control platform.

[0084] Step 3, the transmission bearer management platform queries the time path tracked by C and D, which is: Time Source -> A -> B -> C -> D. The upstream device with the most degraded time synchronization network performance on this time path is device C.

[0085] Step 4: The transmission bearer management platform sends the C device ID to the probe network management system, which then determines the fault location as the C device or its upstream link. It then dispatches a fault repair work order to the maintenance personnel.

[0086] Step 5: The probe network management system sends a command to the Y probe device to switch probe Y to time source mode.

[0087] Step 6: Probe Y ceases its original task of measuring the input time signal and instead outputs a higher-priority standard time signal to the synchronization network. At this point, access device C switches to tracking the time signal output by probe Y and continues to output a time signal downstream. Both access devices C and D now originate from probe Y. Exceeding limits alarms on both C and D will be cleared at this time.

[0088] Step 7: After the maintenance personnel complete the emergency repair, the probe network management system sends a command to probe Y to switch probe Y to measurement mode.

[0089] Step 8: After probe Y switches to the measurement mode, access device C will automatically switch back to tracking the original B, and the network will return to its initial state.

[0090] Example 2:

[0091] like Figure 1 and Figure 4 As shown, this embodiment provides a device for optimizing the performance of a time synchronization network. This device is applied to a synchronization network probe monitoring system and includes multiple probe devices and a probe network management device.

[0092] The probe equipment includes:

[0093] The first acquisition unit 10 is used to measure and acquire the time synchronization network performance of the access device.

[0094] The first judgment unit 20 is connected to the first acquisition unit 10 and is used to determine whether the performance of the time synchronization network has deteriorated.

[0095] The first transmission unit 30 is connected to the first judgment unit 20 and is used to report the time synchronization network performance degradation fault information to the probe network management device when the time synchronization network performance deteriorates.

[0096] The switching unit 40 is used to switch between measurement mode and time source mode;

[0097] The measurement mode is that the probe device measures the input time signal based on the standard Global Navigation Satellite System (GNSS) signal; the time source mode is that the probe device itself acts as a time source, tracks the standard GNSS signal, and outputs a standard time signal to the access device.

[0098] The probe network management equipment includes:

[0099] The identification unit 50 is used to identify faults based on time synchronization network performance degradation fault information and obtain the fault location.

[0100] The second transmission unit 60 is connected to the identification unit 50 and is used to send a first switching instruction to the switching unit 40 according to the time synchronization network performance degradation fault information. The switching unit 40 switches from the measurement mode to the time source mode according to the first switching instruction. The second switching instruction is sent to the switching unit 40 according to the fault resolution receipt. The switching unit 40 switches from the time source mode to the measurement mode according to the second switching instruction.

[0101] Specifically, the identification unit 50 includes:

[0102] The settings module is used to set an analysis time window;

[0103] The receiving module is used to receive fault information about the time synchronization network performance degradation of the probe device;

[0104] The identification module, connected to both the setting module and the receiving module, is used to identify the fault location within a set analysis time window. The specific steps for the identification module to identify the fault location are as follows:

[0105] Within the set analysis time window, if the receiving module receives time synchronization network performance degradation fault information from only one probe device, the identification module identifies the synchronization network device monitored by that single probe device as the fault location. If the receiving module receives time synchronization network performance degradation fault information from multiple probe devices, the receiving module reports the IDs of the synchronization network devices monitored by the multiple probe devices to the transmission bearer management and control platform, and receives the ID of the upstream synchronization network device sent by the transmission bearer management and control platform. Then, the identification module identifies the fault location as the upstream synchronization network device or its upstream link. Wherein: the upstream synchronization network device is the upstream time synchronization network performance degradation device found by the transmission bearer management and control platform after receiving the ID of the time synchronization network device with degraded performance, querying the time path tracked by the time synchronization network device with degraded performance, and following the time tracking path.

[0106] To enable maintenance personnel to quickly handle faults, the probe network management device also includes a preset unit, which is connected to the identification unit 50. The preset unit is used to look up the corresponding fault type and the corresponding handling method from the preset policy library according to the fault location, generate a work order and dispatch it to the maintenance personnel, who can then quickly handle the fault according to the work order.

[0107] The first judgment unit 20 includes:

[0108] The first setting module is used to set the time deviation limit;

[0109] The first calculation module is used to calculate the absolute value of the time deviation in the performance of the time synchronization network;

[0110] The first comparison module is connected to the first setting module and the first calculation module respectively, and is used to compare the absolute value of the time deviation in the time synchronization network performance with the set time deviation limit.

[0111] The first determination module, connected to the first comparison module, is used to determine whether the time synchronization network performance has deteriorated based on the comparison result of the first comparison module. If the absolute value of the time deviation in the time synchronization network performance does not exceed the set time deviation limit, it is determined that the time synchronization network performance has not deteriorated. If the absolute value of the time deviation in the time synchronization network performance exceeds the set time deviation limit, it is determined that the time synchronization network performance has deteriorated.

[0112] The principle and implementation process of Example 2 are the same as those of Example 1. The identical parts will not be described again.

[0113] Both Examples 2 and 1 enable the probe device to switch between measurement mode and time source mode. (After the time synchronization network performance deteriorates and before maintenance personnel complete fault repair, the probe device automatically switches from measurement mode to time source mode, acting as a time source to track standard GNSS signals and output standard time signals to the access devices. After the fault is resolved, the probe device automatically switches from time source mode back to measurement mode.) This automatically optimizes and improves the network's time synchronization network performance accuracy, automating and ensuring the reliability of the time synchronization network fault root cause localization process. Examples 1 and 2, using probe devices and probe network management devices, optimize and improve the time synchronization network performance accuracy during the transition phase after detecting time synchronization network performance degradation.

[0115] Based on the same technical concept as Embodiment 1, the electronic device provided in this embodiment includes a memory and a processor. The memory stores a computer program. When the processor runs the computer program stored in the memory, the processor executes the time synchronization network performance optimization method described in Embodiment 1.

[0117] Based on the same technical concept as in Embodiment 1, this embodiment provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the time synchronization network performance optimization method described in Embodiment 1.

[0118] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
