Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The fault processing system provided by the embodiment of the application can be applied to an application environment shown in fig. 1. The remote radio unit 102 and the baseband processing unit 104 communicate with each other through optical fibers, and the baseband processing unit 104 and the network management platform 106 communicate with each other through a network. The baseband processing unit 104 may cascade a plurality of remote radio units 102 through an optical port, and the number of cascaded remote radio units 102 may be 24. Reporting the state parameter of at least one remote radio unit to a baseband processing unit, detecting the baseband processing unit based on the state parameter, generating alarm messages of the remote radio units corresponding to the state parameter respectively if the state parameter meets a preset alarm condition, sending the generated alarm messages to a network management platform, analyzing the alarm messages through the network management platform to obtain an analysis result, and sending the analysis result to a user terminal so as to prompt related staff to timely perform fault processing on the corresponding remote radio units.
In one embodiment, as shown in fig. 2, a fault handling system is provided, the fault handling system comprising at least one data acquisition unit and a baseband processing unit, wherein:
the data acquisition unit is used for acquiring the state parameters of the remote radio unit and reporting the state parameters to the baseband processing unit.
The data acquisition unit is connected with the remote radio unit, and can be arranged in the remote radio unit or arranged outside the remote radio unit according to actual requirements. The state parameters include a level signal and an alarm enabling switch signal, the level signal can be obtained through a GPIO pin arranged on the processing unit, and the level signal includes a high level signal and a low level signal. The high level signal can be set to be in a normal state and the low level signal can be set to be in an alarm state according to actual requirements. The alarm enabling switch signal may be generated by triggering an alarm enabling switch, and the alarm enabling switch may be set according to actual requirements, for example, may be set by a network management platform shown in fig. 1.
Specifically, after the data acquisition unit acquires the state parameters of the corresponding radio frequency processing units, the acquired state parameters are reported to the baseband processing unit through a CPRI interface in the radio frequency processing units, wherein the state parameters can be represented in a control word in the CPRI, the control word comprises level signal bits and alarm enabling switch bits, the level signal bits are used for storing data representing level signals, the alarm enabling switch bits are used for storing data representing alarm enabling switch signals, and the format of the bits in the control word is set in a mode of the level signal bits and the alarm enabling switch bits. For example, if the level signal in the state parameter is a high level signal, the data stored in the bit of the corresponding control word is 1. If the level signal in the state parameter is a low level signal, the data stored in the bit of the corresponding control word is 0. If the alarm enable switch signal in the state parameter characterizes that the alarm enable switch is opened, the data stored in the bit of the corresponding control word is 1. If the alarm enable switch signal in the state parameter characterizes the alarm enable closure, the data stored in the bit of the corresponding control word is 0.
Further, the level signal of the radio frequency processing unit has 6 paths, each path of level signal has a corresponding alarm enabling switch signal, each path of level signal occupies one bit in the control word, and each alarm enabling switch signal occupies one bit in the control word. For example, the level signals include 1, 2, 3, 4, 5 and 6 level signals, one control word includes 8 bits, byte 1 and byte 2, the first 6 bits of byte 1 are used for storing alarm enabling switch signals corresponding to 1, 2, 3, 4, 5 and 6 level signals respectively, and the second two bits of byte 1 and the first four bits of byte 2 are used for storing 1, 2, 3, 4, 5 and 6 level signals respectively.
The baseband processing unit is used for detecting based on the state parameters, and generating an alarm message of the remote radio unit corresponding to the state parameters if the state parameters meet preset alarm conditions.
The preset alarm condition may be that the alarm enabling switch signal characterizes that the alarm enabling switch is turned on, and the level signal is a low level signal.
Specifically, the baseband processing unit acquires the state parameters of the remote radio unit through the CPRI interface, monitors the remote radio unit acquiring the state parameters, and if the alarm enabling switch signal of the remote radio unit is determined to be on according to the position of the bit in the control word in the CPRI and the data stored in the bit, and the level signal is a low level signal, determines that the state parameters of the remote radio unit meet the preset alarm condition, and generates an alarm message of the remote radio unit. It can be understood that the fault processing system includes at least one remote radio unit, that is, when there are a plurality of remote radio units cascaded with the baseband processing unit, if the baseband processing unit receives the state parameters of at least two remote radio units, the corresponding remote radio units can be monitored according to the positions of the at least two state parameters in the control word, and if the state parameters of the at least two remote radio units meet the preset alarm condition, the alarm messages of the remote radio units corresponding to the state parameters are generated. In other words, when more than two data acquisition units exist in the fault processing system, the baseband processing unit acquires more than two state parameters, judges each state parameter, and if the preset alarm condition is met, determines an alarm message of the radio frequency pulling unit corresponding to the state parameter meeting the preset alarm condition.
In the fault processing system, after the state parameters of the remote radio units are acquired, the state parameters are forwarded to the baseband processing unit, the baseband processing unit carries out alarm detection on the state parameters and generates alarm messages of the remote radio units corresponding to the state parameters, the remote radio units do not need to carry out alarm detection and generate alarm messages based on the state parameters, and then the remote radio units carry out analysis and forwarding through the baseband processing unit, so that the alarm processing time of the remote radio units is shortened, and the real-time performance of the remote radio unit alarm is improved.
Furthermore, in order to improve the real-time performance of the remote radio unit alarm, the hardware cost is further reduced. Based on the high real-time requirement of the FPGA chip, under the condition that the quantity of pins of the FPGA chip is relatively large and the quantity of hardware GPIO pins of a CPU in the remote radio unit is relatively small, the state parameters of the remote radio unit can be obtained through the FPGA chip arranged in the remote radio unit.
In one embodiment, the data acquisition unit is an FPGA chip, and the FPGA chip is configured to acquire a level signal and an alarm enabling switch signal of the remote radio unit.
Specifically, 6 external alarm flat cables of the remote radio unit are all directly connected to GPIO pins of an FPGA chip of the RRU, and the FPGA directly reports the pin states on the GPIO pins and the states of external alarm enabling parameters on the RRU to the BBU through a CPRI interface. Wherein the pin state may be understood as a level signal and the state of the external alarm enabling parameter may be understood as an alarm enabling switch signal. As shown in fig. 3, which is a schematic diagram of a connection structure of an RRU in an embodiment, 6 external alarm cables of a remote radio unit are all directly connected to GPIO pins of an RRU FPGA chip, one side of the FPGA communicates with macs in a CPU through RMII, and the other side of the FPGA is provided with a CPRI interface.
It can be understood that the FPGA chip in the remote radio unit is used for acquiring the state parameters and reporting the state parameters to the baseband processing unit, so that the pin number requirement and the interrupt number requirement of the CPU in the remote radio unit can be reduced, the requirement of the CPU chip type selection of the RRU is reduced, and the hardware cost is reduced to a certain extent.
In the process of fault processing, if faults such as abnormal power failure exist, in order to ensure the reliability of fault processing, state parameters can be timely reported to the baseband processing unit when the RRU is powered down, and a charging and discharging module is arranged in the RRU. In other words, when the RRU is powered down, the charging and discharging module supplies power, so that the data acquisition unit in the RRU reports the acquired state parameters to the baseband processing unit.
In one embodiment, the remote radio unit further comprises a charge and discharge module connected with the data acquisition unit; and the charge-discharge module is used for supplying power to the processing unit under the condition that the external power supply of the data acquisition unit is powered off, so that the data acquisition unit reports the state parameters to the baseband processing unit. The charge-discharge module may be one capacitor, or two capacitors may be connected in parallel, and the number of the capacitors is not limited. As shown in fig. 4, the remote radio unit further includes a charge-discharge module connected to the data acquisition unit.
It can be understood that a charge and discharge module is connected in parallel in the FPGA power supply. Under the condition that external alarms of the RRU are generated, if the mains supply (220V) of the RRU and a storage battery in the equipment are powered down and disabled, the charge and discharge module can timely supply power to the FPGA, and the state parameters are uploaded. When the RRU is damaged by people, the RRU is completely powered down while an external alarm is generated, and the charge-discharge module can support the FPGA to finish reporting of state parameters. Because the response of the FPGA is of a subtle level, the capacity of the charge-discharge module is enough to enable the FPGA of the RRU to continuously work for 20MS after the whole RRU is powered down and disabled, and the FPGA of the RRU is enough to support the FPGA of the RRU to send the pin state on the GPIO to the FPGA of the BBU through CPRI. After receiving the external alarm generated by the RRU corresponding to the CPRI, the FPGA of the BBU processes the alarm and reports the alarm, and the network management platform can also receive the external alarm of the RRU. The charging and discharging module is arranged, so that external warning can be generated when the RRU has no storage battery or the storage battery is broken, the reliability of warning is ensured, and meanwhile, the necessity of electric power storage is reduced, thereby indirectly reducing the hardware cost.
In one embodiment, a baseband processing unit is provided, the baseband processing unit including an alarm detection module and a processor module, wherein: the alarm detection module is used for detecting based on the state parameters, triggering to generate alarm interruption and reporting the alarm interruption to the processor module if the state parameters meet the preset alarm conditions. And the processor module is used for responding to the alarm interrupt and generating an alarm message of the remote radio unit corresponding to the state parameter.
One side of the alarm detection module is connected with the processor module through an RMII IRQ, and the other side of the alarm detection module is provided with a CPRI which communicates with the RRU through an optical fiber. The processor module communicates with the network management platform through a network port arranged on the baseband processing unit. The alarm detection module may be an FPGA chip.
Specifically, after the processing unit of the RRU reports the state parameter, the alarm detection module in the baseband processing unit monitors the state of each external alarm of the RRU currently on line according to the position of the control word in the CPRI, that is, monitors the level signal and the alarm enabling switch signal of each alarm, when the alarm enabling switch signal in the state parameter characterizes that the alarm enabling switch is turned on according to the control word in the CPRI and the level signal is a low level signal, the processor module triggers to generate an interrupt, reports the interrupt generated by triggering to the processor module in the baseband processing unit, and generates an alarm message corresponding to the RRU according to the state parameter after the processor module receives the interrupt.
Further, in response to the alarm interrupt, generating an alarm message of the remote radio unit corresponding to each of the state parameters may be implemented in the following manner:
determining a control word in a preset format based on the state parameter; if the alarm enabling state data in the target enabling bit in the control word represents that the alarm enabling is opened and the level signal of the level signal byte corresponding to the target enabling bit represents abnormality, determining that the state parameter meets the preset alarm condition, and triggering to generate alarm interrupt.
Wherein the target enable bit may be understood as an alarm enable switch bit. Whether each bit in each byte in the baseband processing unit is a level signal for a stored remote radio unit or a stored alert enable switch signal is preset. It will be appreciated that the identity of the failed remote processing unit and the alarm line in the remote processing unit cascaded with the baseband processing unit may be determined based on the location of the bit in the byte. The generated alarm message carries the remote radio unit identifier and the fault type.
Specifically, the alarm detection module in the baseband processing unit monitors the state of each path of external alarm of the RRU currently on line according to the position of the control word in the CPRI, and when the alarm enabling switch signal in the control word is monitored to represent that the alarm enabling switch is opened and the level signal is a low level signal, the alarm detection module triggers to generate an interrupt and reports the interrupt generated by triggering to the processor module in the baseband processing unit. And the processor module acquires the state on the control word and the position of the bit in the control word on the CPRI on the baseband processing unit by calling the callback function after receiving the interrupt, determines a target line of the target RRU for generating the alarm, and then forms a corresponding alarm message according to the target RRU and the target line for generating the alarm.
For example, the alarm detection module of the baseband processing unit monitors the state of each external alarm of the RRU currently on line according to the position of the control word in the CPRI, where the alarm enable on of the control word of the CPRI is 1, the alarm enable off is 0, the gpio normal state is 1, and the gpio alarm state is 0. If the corresponding external alarm state is changed from 1 to 0 and the external alarm enabling switch is turned on, namely, the alarm enabling switch signal represents that the alarm enabling switch is turned on, the level signal is a low level signal, and the FPGA of the BBU triggers an interrupt to inform the CPU of the BBU. As shown in fig. 5, the maximum concatenation 24 RRUs of the BBU and the support RRU, the maximum concatenation 24 RRU control word margins that need to be reserved on the BBU, one RRU has 6 external alarms to enable +6 external alarms, 12 BITs are needed, 36 bytes are needed for the concatenation 24 RRUs, the total of 36 bytes is 288 BITs, and 288 BITs are allocated one by one according to the concatenation positions of the RRUs. If the number of the 6 RRUs under the first optical port is 1-6, the number of the 6 RRUs under the second optical port is 7-12. The external alert information location of RRU No. 1 is that the first 6 BITs of 288 BITs are enabled and 7-12 BITs are GPIO alert status. The external alarm information position of the RRU No. 2 is 13-18 BIT enable, 19-24 BIT GPIO alarm states and so on. The method can ensure that all RRU external alarms can be normally processed at the BBU side when the normal processing system is in the maximum cascade number of RRUs (1 BBU+24 RRUs).
Under the condition that BBU+24 RRUs are operated in cascade, when the CPRI upper rate is 4915.2Mbps, as shown in a 4915.2Mbps CPRI rate basic frame format in fig. 6, the FPGA of the BBU can detect the control words in real time, and if the external alarm state on the on-line RRU is changed from 1 to 0 and the external alarm enable is opened, the CPU of the BBU is triggered to be interrupted to notify, and the external alarm is generated. It will be appreciated that the amount of time from the generation of an alarm on the RRU to the receipt of an interrupt by the CPU of the BBU is typically on the order of a subtle.
The baseband processing unit performs alarm detection on the state parameters and generates the alarm messages of the remote radio units corresponding to the state parameters, the remote radio units do not need to perform alarm detection and generate alarm messages based on the state parameters, and the alarm messages are analyzed and forwarded through the baseband processing unit, so that the alarm processing time of the remote radio units is shortened, and the real-time performance of the remote radio units in alarm is improved.
Further, in an embodiment, the processor module is further configured to send an alarm message to the network management platform. After the network management platform receives the external alarm report, the network management platform knows that the RRU at the corresponding position generates the alarm and can immediately process the alarm. It can be understood that the network management platform analyzes the alarm message when receiving the alarm message to obtain the failed target RRU and the failed line, so that related personnel can be prompted to process in time.
In another embodiment, as shown in fig. 7, a fault handling system is provided, where the fault handling system includes at least one remote radio unit and a baseband processing unit, the remote radio unit includes a processing unit, and a charge and discharge module connected to an alarm enable switch bit unit, and the baseband processing unit includes an alarm detection module and a processor module. The remote radio unit and the baseband processing unit are communicated through optical fibers, and the alarm detection module and the processor module are communicated through RMII IRQ.
The data acquisition unit is used for acquiring the state parameters of the remote radio unit and reporting the state parameters to the baseband processing unit; under the condition that an external power supply of the data acquisition unit is powered off, the charging and discharging module supplies power to the data acquisition unit, so that the data acquisition unit reports the state parameters to the baseband processing unit. The alarm detection module is used for detecting based on the state parameters, triggering to generate alarm interruption and reporting the alarm interruption to the processor module if the state parameters meet the preset alarm conditions. The alarm detection module is also used for determining a control word in a preset format based on the state parameters; if the alarm enabling state data in the target enabling bit in the control word represents that the alarm enabling is opened and the level signal of the level signal byte corresponding to the target enabling bit represents abnormality, determining that the state parameter meets the preset alarm condition, and triggering to generate alarm interrupt.
In one embodiment, as shown in fig. 8, the data acquisition unit in the fault processing system is an FPGA chip, the charge-discharge module is a capacitor, the alarm detection module is an FPGA chip, and the processor module is a CPU. In the fault processing system, the RRU and the BBU communicate through optical fibers, 6 external alarm flat cables of the remote radio unit are all directly connected to GPIO pins of an FPGA chip in the RRU, communication is carried out between one side of the FPGA chip in the RRU and Mac of a CPU through RMII, a CPRI interface is arranged on the other side of the FPGA chip in the RRU, a capacitor is connected with the FPGA chip in parallel, one side of the FPGA chip in the BBU and Mac of the CPU in the BBU are connected through RMII IRQ, and CPRI is arranged on the other side of the FPGA chip in the BBU and communicates with the RRU through optical fibers. The CPU in BBU communicates with the network management platform through the network port set in the baseband processing unit.
Specifically, the FPGA of the RRU directly reports the pin state on the GPIO and the state of the external alarm enabling parameter on the RRU to the BBU through the CPRI interface, the FPGA of the BBU monitors the state of each path of external alarm of the RRU on line currently according to the position of the control word in the CPRI, the alarm enabling on-state on the CPRI control word is 1, the alarm enabling off is 0, the GPIO normal state is 1, and the GPIO alarm state is 0. If the corresponding external alarm state is changed from 1 to 0 and the external alarm enabling is opened, the FPGA of the BBU triggers an interrupt to inform the CPU of the BBU, and after the CPU of the BBU receives the interrupt trigger, a callback function is called to inquire the state on the control word on the CPRI, determine the fault of the target line of the target RRU, and then directly form a corresponding alarm message to be sent to a network management platform. After receiving the alarm message, the network management center determines the target RRU and the fault position so as to enable relevant staff to process the fault in time.
In the above embodiment, the baseband processing unit performs alarm detection on the state parameters and generates the alarm message of the remote radio unit corresponding to the state parameters, so that the remote radio unit does not need to perform alarm detection and generate the alarm message based on the state parameters, and then analyzes and forwards the alarm message through the baseband processing unit, thereby shortening the alarm processing time of the remote radio unit, improving the alarm instantaneity of the remote radio unit, and enabling the processing unit in the RRU to report the acquired state parameters to the baseband processing unit by connecting a charge and discharge module in parallel in the FPGA power supply, and ensuring the reliability of fault processing under the condition that the RRU is powered down.
