Step 206：User A and user B carries out one-way video call；
Step 207：During carrying out one-way video call, user A ViWiFi clients continue to monitor
WiFi network quality residing for user A；It was found that active user A WiFi mass possesses two-way video call
Bandwidth requirement, user A ViWiFi clients automatically initiate standard two-way video call request to AS；
In other words, user A ViWiFi clients send re-INVITE message to AS；
Wherein, user A ViWiFi clients a rowers in the SDP entrained by re-INVITE it is bright=send,
And calling number and called media address are added in re-INVITE message, disappear to AS initiating business requests
Breath, that is, send re-INVITE message.
Step 208：AS is received after business request information, and business request information is sent to called (user B)；
Here, AS receives business request information (re-INVITE message) afterwards, it is necessary to please to the business received
Message is asked to be transmitted relevant treatment, then (new re-INVITE disappears by the business request information after processing
Breath) be sent to it is called.
Step 209：User B ViWiFi clients are received after business request information, send response message (200
OK message) to AS；
Step 210：AS is received after response message, and response message (200OK is sent to caller (user A)
Message)；
Here, the effect of step 207 to 210 is to carry out media negotiation (two-way video call).
Step 211：User A and user B carries out two-way video call；
Step 212：User A ViWiFi clients send BYE message to AS, by original list
