In this embodiment, the baseband unit testing device includes a control module 1 and a testing module 2, wherein the control module 1 is used for controlling the baseband unit 3 and the testing module 2, and the testing module 2 is used for testing different functions of the baseband unit 3. Specifically, in this embodiment, a first end of the control module 1 is connected to a debug end of the baseband unit 3, and a second end of the control module 1 is connected to a debug end of the test module 2. The control module 1 is configured to send a forward test instruction, a return test instruction, an uplink decoding test instruction, or a throughput rate test instruction to the test module 2 and the baseband unit 3 through a first end and a second end of the control module. It can be understood that, in order to ensure the normal running of the test, when the control module 1 transmits any one of the forward test instruction, the return test instruction, the uplink decoding test instruction, or the throughput rate test instruction, it is necessary to simultaneously transmit the instruction to the test module 2 and the baseband unit 3.
In this embodiment, the forward test instruction, the return test instruction, the uplink decoding test instruction, and the throughput test instruction are respectively used to instruct the baseband unit 3 and the test module 2 to perform the forward test, the return test, the uplink decoding test, and the throughput test. The forward test refers to testing the forward interface of the baseband unit 3; the backhaul test refers to testing the backhaul interface of the baseband unit 3; the uplink decoding test refers to a signal decoding test for the uplink of the baseband unit 3; throughput rate testing refers to testing the amount of transmission data per unit time of the baseband unit 3.
The test module 2 is used for carrying out a forward test between the data transmission port 4 and the baseband unit 3 when receiving a forward test instruction; the data transmission port 4 is used for carrying out a backhaul test between the baseband unit 3 and the data transmission port when receiving a backhaul test instruction; when receiving the uplink decoding test instruction, the uplink decoding test is carried out between the data transmission port 4 and the baseband unit 3; and the data transmission port 4 is connected in a loop when receiving the throughput rate test instruction, so that the baseband unit 3 performs throughput rate test.
In this embodiment, the debug end of the test module 2 is connected to the first end of the control module 1, and is configured to receive a forward test instruction, a return test instruction, an uplink decoding test instruction, and a throughput rate test instruction sent by the control module 1.

and step 101, when a forwarding test instruction sent by the control module is received, forwarding test is carried out between the data transmission port and the baseband unit.
In this embodiment, after the control module 1 sends the forwarding test instruction to the test module 2 and the baseband unit 3, the baseband unit 3 and the test module 2 can execute respective preset forwarding test programs, the test module 2 starts data transmission with the baseband unit 3 through the data transmission port 4, and the baseband unit 3 and the test module 2 complete forwarding test through mutual cooperation. After the forward test is completed, the baseband unit 3 may generate a forward test result, the control module 1 may obtain the forward test result through the debug end of the baseband unit 3, and confirm whether the forward test is passed according to the forward test result, if not, the control module 1 may notify related personnel through an alarm manner.

After the return test is completed, the test module 2 generates a return test result, and the control module 1 can obtain the return test result through the debug end of the test module 2 and confirm whether the return test is passed or not according to the return test result.
And 103, when an uplink decoding test instruction sent by the control module is received, an uplink decoding test is carried out between the data transmission port and the baseband unit.
After the control module 1 sends the uplink decoding test instruction to the test module 2 and the baseband unit 3, the baseband unit 3 and the test module 2 can execute respective preset uplink decoding programs, the test module 2 starts to send uplink signals to the baseband unit 3 through the data transmission port 4, and the uplink decoding programs in the baseband unit 3 can perform uplink decoding on the uplink signals.

At this time, the test module 2 performs loop connection on its own data transmission port 4, for example, if the data transmission port 4 includes two data transmission ends connected to two optical ports, the test module 2 may short-circuit the two data transmission ends to complete loop connection. Meanwhile, the baseband unit 3 starts to send test data to the test module 2 through the optical port 5, and the test data sent by the baseband unit 3 returns to the baseband unit 3 after passing through the data transmission port 4 due to the loop connection of the data transmission port 4, so that the throughput rate test program of the baseband unit 3 can analyze the sent test data and the received test data, thereby completing the throughput rate test and generating the throughput rate test result. The control module 1 can obtain the throughput rate test result through the debugging end of the baseband unit 3, and confirm whether the throughput rate test is passed or not according to the throughput rate test result.

When the test module 2 receives the uplink decoding test instruction sent by the control module 1, the control register outputs a second value, and after receiving the second value, the switch switching unit 21 connects the second port with the uplink signal source unit 22, so that the uplink decoding test of the baseband unit 3 is started.

On the basis of the test module, the embodiment of the application also provides a method for controlling the switch switching unit, which comprises the following steps:
step 301, when a forwarding test instruction is received, a control register outputs a first value so as to connect a second port of a switch switching unit with a slave clock unit;

For example, the control module 1 logs in the test device through the debug end of the test module 2, and sends a forwarding test instruction to the test module 2, and after receiving the forwarding test instruction, the test module 2 controls the register to output a first value, for example, the first value is 1.

When the forward 1588 test is performed, the Master clock unit (Master) of the baseband unit 3 sends a "synchronization" message to the Slave clock unit 24 (Slave) of the test module 2, and the sending time T1 is recorded in the first register, and the Slave clock unit 24 (Slave) of the test module 2 receives the "synchronization" message and records the received time T2.

The master clock unit of the baseband unit 3 receives the "Delay request" message and remembers the time T4, and the master clock unit of the baseband unit 3 embeds T4 in a "Delay response" (delay_resp) message, which is sent to the slave clock unit 24 of the test module 2. The slave clock unit 24 of the test module 2 can calculate the time Offset (Offset) between itself and the master clock unit of the baseband unit 3 according to T1, T2, T3 and T4, and send the time Offset (Offset) to the control module 1 as a forwarding test result. The control module 1 determines whether the time Offset (Offset) is within 30ns, if so, the forward transmission 1588 passes the test, otherwise, it does not pass.
On the basis of the test module, the embodiment of the invention also provides a method for performing forward test on the baseband unit, which comprises the following steps:
when a forwarding test instruction is received, the forwarding test message is transmitted between the slave clock unit and the baseband unit through the first connecting end, the second connecting end, the third connecting end and the fourth connecting end, so that the slave clock unit performs the forwarding test according to the forwarding test message and generates a forwarding test result, and then the forwarding test result is sent to the control module.

In this embodiment, after receiving the backhaul test instruction sent by the control module 1, the baseband unit 3 and the test module 2 transmit the backhaul test message through the fifth connection end SFPB4 and the slave clock unit on the baseband unit 3 by the master clock unit 23 on the test module 2, so that the baseband unit 3 performs backhaul test according to the backhaul test message. Specifically, after the control module 1 sends a backhaul test instruction to the baseband unit 3 and the test module 2, the control module may log in the baseband unit 3 through a debug end of the baseband unit 3, and control a slave clock unit of the baseband unit 3 to run, and a backhaul 1588 test is performed between the master clock unit 23 on the test module 2 and the slave clock unit of the baseband unit 3. The procedure of the backhaul 1588 test is similar to the procedure of the foregoing backhaul 1588 test, and will not be repeated in this embodiment. After the backhaul 158 is tested, the slave clock unit of the baseband unit 3 outputs a time Offset (Offset) with the master clock unit 23 of the test module 2, and sends the time Offset (Offset) as a backhaul test result to the control module 1, and the control module 1 determines whether the time Offset (Offset) is within 30ns, if yes, the backhaul 1588 test passes, otherwise, the time Offset (Offset) does not pass.

In this embodiment, after receiving the uplink decoding test instruction sent by the control module 1, the baseband unit 3 and the test module 2 connect the second end of the switch switching unit 21 with the uplink signal source unit 22, and the uplink signal source unit 22 sends uplink signals to the baseband unit 3 through the first connection end SFPB0, the second connection end SFPB1, the third connection end SFPB2 and the fourth connection end SFPB3, so that the baseband unit 3 performs an uplink decoding test according to the received uplink signals. For example, the control module 1 logs in the test device through the debug end of the test module 2, and sends an uplink decoding test instruction to the test module 2, and after receiving the uplink decoding test instruction, the test module 2 controls the register to output a second value, for example, the second value is 2. At this time, the second port of the switch switching unit 21 is connected to the upstream signal source unit 22 of the test module 2, and the upstream signal source unit 22 starts to send an upstream signal, for example, a 5G upstream signal, to the baseband unit 3. Meanwhile, the control module 1 logs in the baseband unit 3 through the debugging end of the baseband unit 3, the baseband unit 3 is controlled to start executing an uplink decoding program, the uplink decoding program decodes the 5G uplink signal to obtain the number of error packets, the number of error packets is used as an uplink decoding test result to be sent to the control module 1, the control module 1 judges whether the number of error packets is 0, if so, the uplink decoding test is passed, otherwise, the uplink decoding test is not passed.
On the basis of the test module, the embodiment of the invention also provides a method for carrying out uplink decoding test on the baseband unit, which comprises the following steps:
when an uplink decoding test instruction is received, an uplink signal source unit is utilized to send uplink signals to a baseband unit through a first connecting end, a second connecting end, a third connecting end and a fourth connecting end, so that the baseband unit carries out uplink decoding test according to the uplink signals and generates an uplink decoding test result, and then the uplink decoding test result is sent to a control module.
On the basis of the above embodiment, the switch switching unit 21 is specifically configured to short-circuit the first connection end SFPB0 and the second connection end SFPB1, short-circuit the third connection end SFPB2 and the fourth connection end SFPB3 when receiving the throughput rate test instruction, so that the baseband unit 3 performs throughput testing through the first front light port SFPA0, the second front light port SFPA1, the third front light port SFPA2 and the fourth front light port SFPA3 when receiving the throughput rate test instruction, and sends the throughput rate test result to the control module 1 after generating the throughput rate test result.
In this embodiment, after receiving the throughput rate test instruction sent by the control module 1, the baseband unit 3 and the test module 2 short-circuit the first connection end SFPB0 and the second connection end SFPB1, and short-circuit the third connection end SFPB2 and the fourth connection end SFPB3 by the switch switching unit 21, so that when receiving the throughput rate test instruction, the baseband unit 3 performs throughput rate test through the first front light transmission port SFPA0, the second front light transmission port SFPA1, the third front light transmission port SFPA2 and the fourth front light transmission port SFPA 3. Illustratively, the control module 1 logs in the test device through the debug end of the test module 2, and sends a forwarding test instruction to the test module 2, and after receiving the forwarding test instruction, the test module 2 controls the register to output a third value, for example, the first value is 3. At this time, the switching unit 21 shorts the first connection terminal SFPB0 and the second connection terminal SFPB1, and shorts the third connection terminal SFPB2 and the fourth connection terminal SFPB 3. Meanwhile, the control module 1 logs in the baseband unit 3 through the debugging end of the baseband unit 3, and controls the baseband unit 3 to run the throughput rate test program. And then, the throughput test program sends the Ethernet packet through the first front optical port SFPA0, the second front optical port SFPA1, the third front optical port SFPA2 and the fourth front optical port SFPA3 according to the maximum capacity, and receives the returned Ethernet packet after loop-back. And the throughput test program outputs the throughput of the Ethernet packet which is checked by the CRC, and sends the throughput to the control module 1 as a throughput rate test result. And the control module 1 judges whether the throughput is greater than 9Gbps, if so, the throughput rate test passes, otherwise, the throughput rate test does not pass. The reason why the throughput rate test is determined to be passed according to whether the throughput is greater than 9Gbps is that the throughput reaches 9Gbps because the maximum rate of the optical port is 10Gbps and the maximum traffic applied by the baseband unit only needs 7Gbps, thereby meeting the throughput rate test requirement.
