Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail hereinafter with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be arbitrarily combined with each other.
Normally, time synchronization between the BBU and radio frequency antennas of different types is completed through a clock source provided by an external device, however, if a communication link between the BBU and the radio frequency antennas is abnormal (for example, a broken link fault occurs in the communication link, etc.), accurate time synchronization between the BBU and the radio frequency antennas cannot be performed, which easily causes that acquired measurement information or configuration maintenance information corresponding to the radio frequency antennas cannot be aligned with real-time running time of the BBU, so that the clock of the whole communication network is abnormal, and the BBU can only locate possible abnormality of the radio frequency antennas through local analysis or single-side speculation, thereby reducing the efficiency of abnormality location.
For example, fig. 1 shows a schematic diagram of a connection relationship between a BBU and a radio frequency antenna provided in an embodiment of the present application. As shown in fig. 1, various devices are installed in the base station room 110: a transmission 111, a first network cabinet 112, a second network cabinet 113, a power supply 114, a backup battery 115, an air conditioning device 116, a monitoring system 117, and the like.
The first network cabinet 112 includes a baseband processing unit 1121, where the baseband processing unit 1121 is connected to a Remote Radio Unit (RRU) 121 through an optical fiber, and the RRU 121 is communicatively connected to a radio antenna 122 (e.g., the RRU 121 is connected to the radio antenna 122 through a feeder).
The second network cabinet 113 includes: a Distributed Unit (DU) 1131 and a Central Unit (CU) 1132. Wherein, the DU 1131 and the active antenna unit (Active Antenna Unit, AAU) 130 are connected through optical fibers.
Note that, the baseband processing unit 1121 performs clock synchronization with the radio frequency antenna 122 through an external device (for example, a global positioning system (Global Positioning System, GPS) device, etc.); the DU 1131 may also perform clock synchronization with the AAU 130 via the GPS device.
If the communication link between the baseband processing unit 1121 and the rf antenna 122 fails, the baseband processing unit 1121 can only locate possible anomalies of the rf antenna 122 (or the RRU 121) through single-side local analysis or single-side estimation, thereby reducing the efficiency of anomaly location. Similarly, if a broken link failure occurs in the communication link between the DU 1131 and the AAU 130, the DU 1131 can determine the possible abnormality only by one-sided local analysis or one-sided estimation, and cannot accurately locate the failure.
The application provides a method, a device, equipment, electronic equipment and a storage medium for determining a dimension time, which are used for solving the problems.
Fig. 2 is a flow chart illustrating a method for determining a dimension time according to an embodiment of the present application. The method for determining the dimension time is applicable to the first device. As shown in fig. 2, the method in the embodiment of the present application includes, but is not limited to, the following steps.
Step S201, acquiring a real-time running time of the first device and a pre-stored first time.
The first time is the absolute time when the first device and the second device complete clock synchronization, and the second device is in communication connection with the first device.
Step S202, determining the dimension measuring time corresponding to the measurement maintenance information according to the first time and the real-time running time.
The measurement maintenance information is information when the first equipment measures the communication parameters and/or working parameter information of the first equipment.
For example, the configuration information of the operation parameters of the first device may include: at least one of a chip voltage in the first device, clock locking information, an operating parameter of the intermediate frequency module, an operating parameter of the radio frequency module, and an antenna parameter. In the actual working process, the first device can acquire the configuration information of the working parameters through a one-key acquisition mode, so that the follow-up use is convenient.
In this embodiment, the second device is in communication connection with the first device, and the real-time running time of the first device and the first time stored in advance are obtained, where the first time is the absolute time corresponding to the time when the first device and the second device complete clock synchronization, so as to facilitate processing of time information; according to the first time and the real-time running time, the corresponding dimension measuring time of the measurement maintenance information is determined, the accurate dimension measuring time can be obtained, so that when the first equipment measures the communication parameters, and/or when the second equipment carries out configuration maintenance on the first equipment, the obtained measurement maintenance information can be accurately butted with the dimension measuring time, the accuracy of the measurement maintenance information is improved, the accurate positioning of the communication faults is facilitated, and the safety of the first equipment is improved.
In some specific implementations, before executing the acquiring the real-time running time of the first device and the pre-stored first time in step S201, the method further includes: and updating the first time every preset time length.
The preset time length is a time length which can be set according to actual requirements, for example, the preset time length is 8 hours, 9 hours and the like. The above-mentioned preset time periods are only examples, and can be specifically set according to actual needs, and other unexplained preset time periods are also within the protection scope of the present application, and are not described herein again.
The first time is updated through the preset time length at each interval, so that the updated first time can reflect the real-time counting condition of the chips of the first equipment in different time periods, and the subsequent positioning accuracy of the fault time length is improved.
In some specific implementations, before executing the acquiring the real-time running time of the first device and the pre-stored first time in step S201, the method further includes: and under the condition that the communication link between the first device and the second device is abnormal, updating the first time according to the time before the first device executes the reset operation or before the first device is powered down.
The time before the first equipment executes the reset operation or before the first equipment is powered off can be recorded more accurately, and the positioning accuracy of the fault duration of the first equipment is improved. The reset operation is that the first equipment is powered off and then powered on, so that the first equipment can be restarted, and the occurrence proportion of communication faults of the first equipment caused by possible abnormality is reduced. The anomalies include: the communication link between the first device and the second device is interrupted, or the first device itself has an abnormality such as a failure.
It should be noted that, the chip counting time is obtained, which time the first device specifically performs the reset operation can be clarified, so that the prestored first time is updated according to the chip counting time, so that the obtained updated first time can represent which time the first device specifically performs the reset operation, and the subsequent accurate positioning of the time period when the first device may malfunction is facilitated, so that the possible abnormality of the first device is examined and processed.
In some embodiments, determining the dimension time corresponding to the measurement maintenance information in step S202 according to the first time and the real-time running time may be implemented as follows.
Fig. 3 is a flow chart illustrating a method for calibrating a time-to-measure according to an embodiment of the present application.
As shown in fig. 3, the calibration method of the time-to-dimension includes, but is not limited to, the following steps:
step S301, determining a calibration coefficient according to the acquired historical jitter time information.
Wherein, the historical jitter time information may include: main frequency deviation information, or delay jitter information obtained by multiple tests, and the like.
Step S302, determining the time to be calibrated according to the updated first time and the real-time running time.
The updated first time can represent an absolute time corresponding to a time when the first device performs the reset operation, and the obtained time to be calibrated can represent a time length (i.e., the time to be calibrated) between the time when the first device is reset and the time when the measurement maintenance information is obtained at present by adding the updated first time and the real-time running time.
Step S303, calibrating the time to be calibrated according to the calibration coefficient to obtain the dimension time.
For example, the time to be calibrated and the calibration coefficient may be subjected to addition processing or multiplication processing, so as to obtain the dimension time corresponding to the measurement maintenance information.
The time to be calibrated is calibrated through the calibration coefficient, so that the dimension time can be more accurate, the dimension time can be ensured to accurately correspond to the measurement maintenance information, and the accuracy of the measurement maintenance information is improved.
In some implementations, the real-time runtime includes: the timing update time and the real-time determined by the chip in the first device based on the core counting function are stored in the second register, and the real-time determined by the chip in the first device based on the core counting function is stored in the third register.
The acquiring the real-time running time of the first device in step S201 may be implemented in the following manner:
under the condition that the identification of the first device for executing the reset operation or the identification of the first device for actively initiating the power-down restarting is obtained, the time in the third register is accumulated in the second register; under the condition that the first equipment is determined to finish reset operation or the first equipment is powered down and restarted, a third register is emptied, a chip in the first equipment starts to reckon, and the reckoned real-time is stored in the third register; and determining the real-time running time according to the time stored in the second register and the time stored in the third register.
The identifier of the first device executing the reset operation is used for indicating that the first device is about to execute the reset operation, and the time in the third register needs to be recorded to ensure the continuity of the time. The identifier of the first device for actively initiating the power-down restart is used for representing that the second device needs to perform the power-down restart, and the time in the third register also needs to be saved and recorded.
By accumulating the time in the third register into the second register under the condition that the identification of the first device for executing the reset operation or the identification of the first device for actively initiating the power-down restarting is obtained, the continuity of the time stored in the second register can be ensured, and the time can be traced back conveniently. Under the condition that the first equipment completes reset operation or the first equipment is powered down and restarted, the third register is emptied, a chip in the first equipment starts to be reckoned, the reckoned real-time is stored in the third register, so that the real-time counting condition of the chip can be represented by the time in the third register, and further, the real-time running time is determined based on the time stored in the second register and the time stored in the third register, for example, the time stored in the second register and the time stored in the third register are added to obtain the real-time running time, and the accuracy of the real-time running time can be ensured.
In some specific implementations, determining the dimension time corresponding to the measurement maintenance information in step S202 according to the first time and the real-time running time includes: acquiring the operation time length of a communication link between the first equipment and the second equipment in a normal state after clock synchronization of the first equipment and the second equipment is completed; determining the fault duration according to the operation duration and the real-time operation time of the communication link in a normal state; and determining the dimension time according to the fault duration and the first time.
The method comprises the steps of obtaining a fault duration by subtracting the running duration of the communication link in a normal state from real-time running time, and representing the time length of possible faults of first equipment through the fault duration so as to facilitate time alignment of measurement maintenance information of the first equipment.
Further, the fault duration and the first time can be added, so that the obtained dimension time can represent the fault duration of the first equipment which is likely to be in fault, and the first time is the absolute time which is stored in advance and can represent the time when the first equipment and the second equipment finish clock synchronization, so that the accuracy of the dimension time is improved.
In some specific implementations, before executing the acquiring the real-time running time of the first device and the pre-stored first time in step S201, the method further includes: acquiring a first moment when the first device is powered on; acquiring a second moment when the first equipment and the second equipment complete clock synchronization; and determining the time deviation according to the first time and the second time.
Wherein the time offset is used to calibrate the dimension time. For example, the time deviation can be represented by a difference value between the second moment and the first moment, so as to represent the time difference from the start of power-up of the first device to the completion of clock synchronization with the second device, thereby enabling the time deviation to further accurately calibrate the dimension time of the first device and improving the accuracy of the dimension time.
For example, the time deviation may be added to the dimension time, so that the dimension time may represent the time of the first device from the power-on, and improve accuracy of the dimension time.
It should be noted that, the first time of powering up the first device may also be the time of restarting and powering up the first device after the first device fails, so as to facilitate the first device to accurately estimate the time of maintenance of the first device, and promote the accuracy of the estimation of the failure duration.
In some implementations, acquiring the real-time runtime of the first device in step S201 includes: acquiring time information recorded by a chip in first equipment; and converting the time information recorded by the chip according to a preset time conversion rule to obtain real-time running time.
The preset time conversion rule may include: and converting the time information recorded by the chip among different time units so that the obtained real-time running time can meet the use requirement of the first equipment.
For example, the chip of the first device starts counting from a certain time, the obtained count number (for example, 1024 count points), and then, based on a time unit (for example, 5 milliseconds (ms) or the like) indicated by each count point defined in advance, the real-time running time corresponding to the 1024 th count point can be calculated as: 1024 x 5 ms=5120 ms=5.12 seconds(s), so that the length of time to obtain a chip record of the first device is 5.12 seconds.
By adopting the method of recording the time by the chip of the first equipment, the use (such as the calling among different programs) inside the first equipment can be facilitated, further, the time information recorded by the chip is converted according to the preset time conversion rule, the real-time running time is obtained, other equipment can acquire the specific running time of the first equipment, so that the time synchronization between the other equipment and the first equipment is facilitated, and the accuracy of clock synchronization is improved.
In some implementations, obtaining time information recorded by a chip in a first device includes: and recording the time in the chip operation process according to the preset application scene and the counting bit width to obtain the time information recorded by the chip.
The preset application scene may include: the method is applied to synchronous scenes among different network element devices, or to scenes needing accurate timing, and the like.
The network element device may include: at least two of a remote radio device, a base station, a server and a terminal. The counted bit width may include the length of a binary number such as 16 bits (bit), 32 bits, or 64 bits expressed in binary numbers, or may include the counted length of different lengths expressed in hexadecimal numbers, or the like. The above counting bit widths are only exemplified, and can be specifically set according to actual needs, and other unexplained counting bit widths are all within the protection scope of the present application and are not described herein.
The time in the chip operation process is recorded through the preset application scene and the counting bit width, so that the obtained time information can be ensured to be suitable for different preset application scenes, the time information recorded by the chip is more accurate, the use requirements in different application scenes are met, and the counting accuracy is improved.
In some implementations, the first time is stored in a first register, the first register is disposed in a memory, a flash memory, and a Solid State Disk (SSD); the first device is a remote radio device, and the second device is a baseband processing unit BBU.
Wherein, remote radio equipment includes: any one of an active antenna unit AAU, a remote radio unit RRU and pRRU (pico RRU). The first register, the second register and the third register may be implemented by any one of a memory (flash), a flash memory and an SSD. For example, in the case where it is determined that the first device supports power-down self-healing, the three registers may be deployed in flash memory; in an application scenario facing software reset, the three registers may be disposed in a reserved memory area.
In the case where it is determined that the first device supports power-down self-healing, a power-down type tag needs to be set, which is used to identify whether the device is actively powered down or powered down due to unpredictable external factors.
It should be noted that the above types of registers are only examples, and specific settings can be performed according to actual needs, and other types of registers that are not described are also within the protection scope of the present application, and are not described herein.
By storing the first time in the first register, the remote radio equipment can determine the dimension time corresponding to the measurement maintenance information based on the first time and the real-time running time of the remote radio equipment under the condition that the communication link between the remote radio equipment and the BBU is abnormal, and the accuracy of the measurement maintenance information is improved.
In some specific implementations, before executing the acquiring the real-time running time of the first device and the pre-stored first time in step S201, the method further includes: clock synchronization with the second device is performed using network time protocol (Network Time Protocol, NTP) network time protocol NTP and/or a precision clock synchronization protocol of the network measurement and control system.
The NTP is an application layer protocol, and is used to synchronize clocks between the client and the server. In this embodiment, NTP may be used to synchronize clocks between the first device and the second device, so as to ensure that two different types of devices can work synchronously, and improve working efficiency.
The precise clock synchronization protocol (Precision Clock Synchronization Protocol) of the network measurement and control system periodically corrects and synchronizes clocks of all nodes (e.g., the first device and the first device, etc.) in the communication network through one synchronization signal, so that the devices in the communication network can be precisely synchronized, and communication efficiency is improved.
Fig. 4 is a flow chart of a method for determining a dimension time according to another embodiment of the present application. As shown in fig. 4, "t" represents a time axis, and the remote radio device completes different operations at different moments.
Wherein at t 0 At moment, the remote radio equipment is electrified and starts to work;
at t 1 At this time, a chip (e.g., any one of an ARM chip, an FPGA chip, and an EPLD chip) in the remote radio starts to start a nuclear counting function for counting real-time running time (i.e., local running time) in the remote radio.
Wherein t is 1 Time and t 0 The difference between moments in time is small (e.g., t 1 -t 0 About 100 ms) that can represent the accuracy of the time of the dimension. In particular, the difference may be determined by time information stored in different registers to facilitate further calibration of the time of the measurements.
At t 1 Time t 2 Between the moments, the remote radio equipment needs to complete the loading of the software version and enter the baseband processing unitAnd synchronizing the row clocks, wherein the communication link between the remote radio and the baseband processing unit is in an abnormal state in the period of time.
When t is reached 2 And at the moment, clock synchronization is completed between the remote radio equipment and the baseband processing unit. At this time, the remote radio equipment needs to record t 2 Absolute time T corresponding to time aboslute2 (e.g. the absolute time T aboslute2 Stored in a first register, the first register being disposed in a memory or flash memory).
The remote radio device can use NTP and/or precise clock synchronous protocol of network measurement and control system to synchronize clock with baseband processing unit.
It should be noted that, after clock synchronization is completed between the remote radio and the baseband processing unit, the remote radio works normally.
In some implementations, the remote radio may also calculate t using equation (1) 3 A dimension time T corresponding to a certain measurement maintenance information before the moment test ：
T test-1 ＝T aboslute2 +(T 1 -T 2 )+X (1)
Wherein T is test-1 Representing t 3 And measuring time corresponding to certain measurement maintenance information before the moment, wherein the measurement maintenance information comprises: information when the radio remote equipment measures communication parameters and/or information when the baseband processing unit carries out configuration maintenance on the radio remote equipment;
T 1 indicating at t the chip in the remote radio 0 A time length corresponding to the real-time running time recorded after the time; for example T 1 ＝t test-1 -t 0 ，T 1 May be stored in a first register. Wherein t is test-1 The time corresponding to the dimension time is represented.
Wherein T is 1 The time obtained by converting the time information recorded by the chip in the remote radio based on a preset time conversion rule. T (T) 2 Representing a second depositThe duration stored in the device after clock synchronization and the communication link in a normal state. For example, as shown in FIG. 4, the chip in the RRU is at t 2 Time t 3 The length of time accumulated between moments. X denotes a coefficient determined based on the obtained historical jitter time information (e.g., main frequency deviation information or delay jitter information obtained by performing a test a plurality of times, etc.).
For example T test 、T 1 、T 2 、T aboslute2 Each may be represented by an unsigned number of bits having a bit width of 32 bits in seconds (second). The register, the first register and the second register corresponding to the core counting function of the chip in the remote radio device all need to be subjected to anti-overflow processing so as to prevent the accumulated bit number of data from exceeding 32 bits. The above bit widths (e.g., 32 bits) of the registers are merely exemplary, and may be specifically set according to actual needs (e.g., a bit width of 16 bits or 64 bits may be used), and the number of bits of other registers that are not described are also within the scope of protection of the present application, which is not described herein.
In some implementations, the first register does not require periodic maintenance, reducing overhead of the central processing unit (Central Processing Unit, CPU). In an application scenario facing software reset, a first register may be disposed in a reserved memory area; in the application scenario facing power-down self-healing, the first register may be deployed in a flash memory.
Because the self-healing power failure occurs in a transient state, other external power failure time cannot be sensed and compensated, the external power failure or the power failure initiated by the software can be distinguished through the power failure type flag bit, and the power failure is classified and processed.
When t is reached 3 At this time, the communication link between the remote radio device and the baseband processing unit is abnormal (for example, the communication link is interrupted, or the remote radio device fails), at this time, the remote radio device cannot perform accurate clock synchronization with the baseband processing unit, but the core counting function of the chip in the remote radio device is always in a normal working state, i.e. the remote radio deviceThe chips in the device remain in a constant count state.
It should be noted that, when the abnormal duration of the communication link between the remote radio device and the baseband processing unit exceeds a preset duration (for example, 3 seconds or 5 seconds, etc.), the remote radio device will automatically perform the reset operation, but before performing the reset operation, the real-time recording time of the chip of the remote radio device will be recorded, for example, the real-time recording time of the chip of the remote radio device is set as the chip counting time, and the chip counting time is used to count the T stored in the first register aboslute2 Performing accumulated update to obtain updated first time, namely T aboslute4 As shown in FIG. 4, T aboslute4 Representation and t 4 Absolute time corresponding to time.
At t 4 At the moment, the remote radio device executes a reset operation.
At t 4 Time t 5 And in the moment, the remote radio equipment needs to finish operations such as loading of software versions.
When t is reached 5 And when the time is over, the operations such as loading of the software version and the like are completed between the remote radio equipment and the baseband processing unit, and a chip in the remote radio equipment starts to start a nuclear counting function for counting the real-time running time in the remote radio equipment.
Wherein t is 5 Time and t 4 The difference between moments in time is small (e.g., t 5 -t 4 About 100 ms) that can represent the accuracy of the time of the dimension. In particular, the difference may be determined by time information stored in different registers to facilitate further calibration of the time of the measurements.
For example, t 4 Recording the absolute time corresponding to the moment in a second register, and recording t 5 Recording absolute time corresponding to the moment in a third register, wherein the second register stores time updated by the first equipment at regular time, and the third register stores real-time determined by a chip in the first equipment based on a nuclear counting function; by the difference between the second register and the third register, the dimension can be embodied Accuracy of time measurement.
At t 5 Time t 6 In this time, since clock synchronization is not completed, the communication link between the remote radio and the baseband processing unit is in an abnormal state.
At t of arrival 6 At the moment, clock synchronization is carried out between the remote radio equipment and the baseband processing unit, and at the moment, the remote radio equipment needs to record the clock and t 6 Absolute time T corresponding to time aboslute6 (e.g. the absolute time T aboslute6 Stored in a first register, the first register being disposed in a memory or flash memory).
Wherein at t 4 After the moment, and under the condition that the communication link between the remote radio equipment and the baseband processing unit is in an abnormal state, the remote radio equipment can also calculate t by adopting a formula (2) 6 A dimension time T corresponding to a certain measurement maintenance information before the moment test-2 ：
T test-2 ＝T aboslute4 +T′ 1 +X (2)
Wherein T is test-2 Representing t 4 Time of day (or t) 5 Time) and a maintenance time corresponding to certain measurement maintenance information;
T′ 1 indicated at t 4 Time of day (or t) 5 Time of day), a duration corresponding to the real-time running time recorded by the chip in the remote radio device, e.g., T' 1 ＝t test-2 -t 4 Or, T' 1 ＝t test-2 -t 5 . Wherein t is test-2 The time corresponding to the dimension time is represented.
In this embodiment, by determining the dimension time of the remote radio by using the core counting function of the chip in the remote radio and the absolute time stored in the first register in advance and capable of representing the clock synchronization between the remote radio and the baseband processing unit, the problem that the dimension time when the communication link between the remote radio and the baseband processing unit is abnormal cannot be accurately aligned with the time of the baseband processing unit can be solved. The method for determining the maintenance time can be suitable for various different radio remote devices, the time alignment between the radio remote devices and the baseband processing unit is consistent in a mode of upgrading a software version, the accuracy of measurement maintenance information is improved, the accurate positioning of communication faults is facilitated, and the safety of the radio remote devices is improved.
