Fig. 4 has provided the detailed process that WSCC and WSCH carry out Wireless LAN testing, and concrete steps are as follows:
Step 402, the configuration request message that WSCH receives and storage WSCC sends, 802.11 agreement wireless device modules are given in configuration then.After finishing configuration, WSCH is in idle condition.Need send the information of acknowledge message if configuring request carries WSCH, then only send acknowledge message to WSCC by WSCH to WSCH.
The current time that needs setting;
There are how many user-defined 802.11 protocol data frames to be sent out;
Delay duration before sending user-defined 802.11 protocol data frames;
When sending user-defined 802.11 protocol data frames, whether need to send acknowledge message to the transmission confirmation of WSCC;
After finishing user-defined 802.11 protocol data frames of transmission, when WSCH receives one 802.11 protocol validation message again, how long need to wait for;
Before sending user-defined 802.11 protocol data frames, what have need user-defined 802.11 protocol data frames that receive;
Before sending user-defined 802.11 protocol data frames, what the user-defined 802.11 protocol data frame types that will receive are;
Whether need to send user-defined 802.11 protocol data frames that receive to WSCC; If this demand is arranged, whether all carry out for user-defined 802.11 protocol data frames of each reception, still only carry out at user-defined 802.11 protocol data frames of last reception;
When receiving each user-defined 802.11 protocol data frame, how long WSCH need wait for;

Below the transfer process between each state is described in detail:
Transmit status 502 is to idle condition 501, in case the packet that the command process that is used to send is finished and do not needed to receive, WSCH will enter idle condition 501 from transmit status 502.
Accepting state 503 is to idle condition 501, in case the command process that is used to receive is finished and do not needed data packets for transmission, WSCH will enter idle condition 501 from transmit status 502.
Transmit status 502 is to accepting state 503, in case the packet that and then has needs to receive after the command process that is used to send is finished, WSCH will enter accepting state 503 from transmit status 502.
Accepting state 503 is to transmit status 502, in case the packet that and then has needs to send after the command process that is used to receive is finished, WSCH will enter transmit status 502 from accepting state 503.
Success;
Failure;
Redundant cyclic check mistake;
Because it is overtime to send affirmation, there are not user-defined 802.11 protocol data frames to send;
Receive the verification failure owing to send, do not have user-defined 802.11 protocol data frames to send;
Owing to send traffic indicator diagram (TIM, traffic indication map) verification failure, do not have user-defined 802.11 protocol data frames to send;
In the time-out time scope, do not receive user-defined 802.11 protocol data frames;
In the time-out time scope, there is not the user to want 802.11 protocol data frames that receive;
Order is confirmed successfully;
Failure is confirmed in order;
User-defined 802.11 protocol data frames of the mistake of sending from WSCH;
Except these information of listing above, message element can also carry more error code.
