As shown in Figure 3:

1. The concentrator issues a command to collect CCO logs by extending the 1376.2 protocol, and after the CCO receives it, it will artificially cut its own stored logs into multiple segments;

2. Reply the total number of log segments and report the logs collected by the current concentrator;

3. Repeat step 2 several times until the last segment is reported to the concentrator;

As shown in Figure 4:

1. The concentrator starts to collect STA logs, and first sends an instruction to start a STA to collect logs through the 1376.2 protocol;

2. The CCO judges whether the STA is online after receiving the instruction. If it is online, it will reply to confirm and start collecting STA logs, otherwise it will reply with a negative frame;

As shown in Figure 5:

1. When the STA receives the log collection message sent by the CCO through the broadband carrier protocol application layer protocol, the STA artificially cuts the log stored by itself into multiple segments;

2. If it is judged that if the time window is not exceeded, the total number of log segments will be returned and the logs collected by the current concentrator will be reported, otherwise the collection will be ended;

3. Repeat step 2 several times until the last segment is reported to the concentrator;

As shown in Figure 6:

1. The concentrator collects the stored STA logs on the CCO;

2. The CCO judges that if the STA log has been collected, it will report the total number of segments and the log collected at the current time, otherwise it will report a denial frame;

3. If it is judged that it is within the time window, repeat step 2 until the collection is completed, otherwise reply a negative frame and end.
