The BSC is used to monitor the status of the BTS.

In the prior art, the power failure of the AC power supply device in the AC/DC power supply subsystem is a very serious power failure accident. In order to take countermeasures against the power failure of the AC power supply device, usually one of the AC/DC power supply subsystems is set. The power failure detecting unit is configured to detect whether the AC power device is powered off. When the AC power device is powered off, the power-down detection unit is triggered to report to the central processing unit (Central Processing Unit; the lower-sized CPU) in the baseband unit (BBU) on the BTS board.

In the process of implementing the present invention, the inventors have found that at least the following problems exist in the prior art: In the prior art, an alarm frame is reported to the BSC in a manner that the CPU uses the software mainly used to upload the alarm frame to the BSC in the BBU. The reporting time value includes the interrupt response time, the queue waiting time, and the sending time. Due to the problem of the software architecture, the reporting time value is usually large, resulting in low reliability and high cost of the existing base station system. Summary of the invention

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a flowchart of a method for reporting an alarm according to Embodiment 1 of the present invention. The execution body of the method reported by the alarm in this embodiment is a processing module designed by the PB in the BBU. As shown in FIG. 1 , the method for reporting an alarm in this embodiment may specifically include the following steps:

Step 100: The processing module in the BBU adopting the PLD design receives an alarm signal that the AC power device is powered off;

Step 101: Acquire a corresponding alarm data packet according to the alarm signal.

Step 102: Send an alarm data packet to the BSC.

Specifically, the processing module of the PLD design is a processing module implemented by using a PLD. The above operations performed by the processing module of the PLD design can be understood as the above operations performed by the PLD. Specifically, the PLD receives the power failure of the AC power device reported by the power failure detecting unit in the AC/DC power supply subsystem. The alarm signal, and then obtain the alarm data packet corresponding to the alarm signal. The alarm data packet here is configured in advance in the PLD. Finally, the obtained alarm data packet is sent to the BSC to inform the BSC that an AC power failure occurs when the AC power supply device in the AC/DC power supply subsystem is powered down. After receiving the alarm data packet, the BSC notifies the staff. Therefore, the staff can obtain the alarm data packet in time and deal with the accident handling in time.

The PLD in this embodiment may be a hardware such as a Field Programmable Gate Array (FPGA) or a Complex Programmable Logic Device (CPLD).

The alarm reporting method in this embodiment reports the alarm data packet to the base station controller through the PLD, and the reporting time value is shorter than that in the prior art. In addition, in order to ensure that the PLD successfully reports the alarm data packet to the BSC after the AC power supply is powered off, a smaller capacitor is required to complete the operation, which effectively reduces the cost of the system. In this embodiment, the PLD can report the alarm signal to the BSC. The reporting time is short. The PLD can report the alarm signal to the BSC successfully. Therefore, with the technical solution of the embodiment, the reliability of the base station system can be effectively improved, and the cost of the base station system can be reduced.

FIG. 2 is a flowchart of a method for reporting an alarm according to Embodiment 2 of the present invention. This embodiment uses a processing module designed by using the FPGA as an example to describe the technical solution of the present invention in detail. As shown in FIG. 2, the method for reporting alarms in this embodiment may specifically include:

Step 200: The processing module of the BBU in the BBU receives an alarm signal that the AC power device is powered off by the power failure detecting unit in the AC/DC power supply subsystem;

Step 201: Determine a connection mode between the BBU and the BSC.

Specifically, the connection mode between the BBU and the BSC may be an E1 mode or a T1 mode connection. It is also possible to use a network cable connection, also known as an IP mode connection.

Step 202: Acquire an alarm data packet corresponding to the alarm signal according to the connection mode.

Step 203: Send an alarm data packet to the BSC.

For each mode connection, a packet in a corresponding format configured by software, such as an E1 packet, a T1 packet, or an IP packet, is pre-written in the FPGA. Packets of various formats are written into the logical internal random access memory (RAM), so that after the FPGA receives the alarm signal, it can directly send the corresponding packet to the BSC without waiting for transmission. Time, you can reduce the length of time that the alarm is reported. For example, in the El mode, after the FPGA receives the alarm signal of the AC power device power failure reported by the power failure detecting unit, the FPGA acquires the E1 packet configured by the software according to the mode for reporting the alarm signal to the BSC, and simultaneously starts the E1. The slot counter sends the configured E1 packet to the BSC according to the pre-configured time slot. The E1 packet is an alarm packet of the E1 mode. Finally, the E1 packet is sent to the BSC through the E1 transmission line.

For the T1 mode, similar to the E1 mode, it only has a stronger transmission rate than the E1 mode. For the IP mode, after the FPGA receives the alarm signal of the AC power device power failure reported by the power failure detecting unit, the FPGA acquires an IP packet configured by the software according to the mode for reporting the alarm signal to the BSC. Includes information such as MAC, UDP, IP, and payload. The FPGA then adds a preamble to the IP packet to generate an alert packet for the IP mode. Finally, the alarm data packet is sent to the BSC through the Fast Ethernet (Fast Ethernet; FE) port.

It should be noted that, between the foregoing step 200 and step 201, the method further includes: filtering and detecting the alarm signal, and determining that the received alarm signal is an alarm signal that the AC power device is powered off.

Specifically, some jitter will inevitably occur when the AC power is used, in order to ensure that the received alarm signal is an alarm signal that the AC power device is powered off. After the FPGA receives the alarm signal, it can filter and detect the alarm signal to determine whether the received alarm signal is an alarm signal of the AC power device power failure. When the judgment is yes, continue with the next steps. The filtering detection time can take lms - 3 ms, preferably 1 ms.

The technical solutions of the present embodiment are compared with the technical solutions of the prior art to embody the technical effects of the technical solutions of the present invention.

In the prior art, in the E1 mode connection scenario, the reporting time value includes an interrupt response time, a filter detection time, a column waiting time, and a sending time. Due to software architecture issues, the interrupt response time is up to tens of ms, which is assumed to be 20ms. The time for filtering detection is assumed to be lms. After the interrupt is responded, if there is exactly one frame in the CPU transmit buffer (buffer), the maximum frame length is 267 bytes, and the waiting time is 0.125x267 = 33.375ms. Assuming that the frame length of the alarm packet to be sent is 50 bytes, the transmission time is 0.125x50 = 6.25ms. Therefore, the El mode reporting time value is: 20ms+lms +33.375ms+6.25ms = 60.625ms „ In the IP scenario, the IP mode reporting time is approximately: CPU response interrupt processing delay + software architecture caused by interrupt response Delay + traffic shaping delay = lms + 20ms + 63ms = 84ms. The TI mode is similar to the El mode and is not analyzed here.

In order to ensure that the board in the BTS still works normally within the length of the above reporting time, Ensure that the alarm packet can be sent to the BSC. In the prior art, it is necessary to set a backup power source in the AC/DC power supply subsystem. Even in a scenario where there is no backup power, you must rely on a large capacitor to support the board to continue working for a period of time in order to send the alarm packet. Taking the DC power consumption of the MICRO AC small base station 187W as an example, the power supply is completely dependent on the power supply capacitor. The PFC capacitor is required as follows:

Cpfc = 2χΡχί/ηχ(υΐ ^Λ 2 - U1 ^A 2) = 2xl87xt/0.88x (400 ^A 2 - 350 ^Λ 2)

= 0.011332t

Assume that t = 100ms, Cpfc = 1133uF;

A 1133uF capacitor means three 470uF capacitors are required.

Regardless of the above-mentioned increase in the backup power supply or the increase in the capacitance, the cost of the base station system is undoubtedly increased. Moreover, it is assumed that the reporting time length tolerated by the base station is within 100 ms, and the alarm frame can be transmitted at most once according to the reporting time value calculated by the above two modes. In addition, the uncontrollability of the software processing time, such as the interrupt response time and the column waiting time are dynamically changed, and the alarm data packet may not be reported to the BSC, resulting in a decrease in the reliability of the base station system. Therefore, the foregoing solution of the prior art has a long reporting time value, a high cost of the base station system, and low reliability.

In the embodiment of the present invention, in the E1 mode connection scenario, the alarm reporting time includes an interrupt response time, a filter detection time, and a transmission time. The interrupt response time is still assumed to be 20ms. The time for filtering detection is still assumed to be lms. The alarm data packet is transmitted on the OML link, and 125us transmits one byte. It is also assumed that the frame length of the alarm data packet is 50 bytes, the transmission time is 0.125x50 = 6.25ms, and the total sharing time is 7.25ms. Therefore, the E1 mode alarm reporting time is: 20ms+lms +7.25ms = 28.25ms. In the IP connection scenario, 0.08us transmits one byte. It is also assumed that the frame length of the alarm packet is 50 bytes, and the transmission time is only 4us, which is almost negligible. The IP mode alarm is 20 time: 20ms+lms = 21 ms.

It is still assumed that the reporting time length tolerated by the base station is within 100 ms, and the reporting time value calculated according to the two modes of the embodiment of the present invention is calculated. In the above 100 ms, in order to ensure reliable reporting, the FPGA adopts three consecutive transmissions. The alarm data packet method, the time is still very abundant, can increase the success rate of reporting the alarm data packet, and enhance the reliability of the base station system. With the technical solution of the embodiment of the present invention, the reporting time is short, and the capacitor is not increased. Therefore, the technical solution of the embodiment of the present invention has lower cost and higher reliability of the base station system.

It should be noted that, after step 100 or step 200 of the foregoing embodiment, the method further includes: cutting off normal traffic between the BBU and the BSC. Specifically, the alarm data packet is set in advance in the FPGA. The priority is the highest. After the FPGA receives the alarm signal of the AC power device power failure reported by the power-down detection unit in the AC/DC power supply subsystem, the FPGA immediately cuts off the normal service between the BBU and the BSC, and sends an alarm packet. Release the channel. This way there is no time to send a wait. It can effectively shorten the length of reporting time.

It should be noted that, after step 100 or step 200 of the previous embodiment, the method further includes: turning off the power amplifier unit in the RRU. Specifically, since the power amplifier unit is the most power-consuming part of the BST, the FPGA first turns off the RRU after the FPGA receives the alarm signal of the AC power device power failure reported by the power-down detection unit in the AC/DC power supply subsystem. The power amplifier unit, for example, can be realized by turning off the power of the power amplifier unit. That is, the FPGA receives the alarm signal of the AC power device power failure reported by the power failure detecting unit in the AC/DC power supply subsystem, immediately stops the power consumption of the power amplifier unit, and saves all the power to send the alarm data packet. In this way, a smaller capacitor is needed to meet the needs of the base station system, and the cost of the base station system can be effectively reduced.

The processing module designed by using other PLD type hardware, such as a CPLD, is the same as the above-mentioned embodiment of the processing module designed by using the FPGA. For details, refer to the description of the foregoing embodiment, and details are not described herein again.
