Step 107, the conference message server parses the received conference invitation request, wherein the related information of the conference is contained in the xml text of the SDP message of the sip message body. The conference message leaving server analyzes the ID of the conference by using the existing xml tool, analyzes whether the received conference ID is matched with the ID in the message leaving server, if so, takes the corresponding video message as the video message to be played, and if not, the step 108 is switched to.
Step 108, the conference message server searches the message according to the analyzed conference theme, if the message with similar and same theme exists, the message is sent as the alternative message,
at this time, the conference message server constructs a message play list, which includes messages customized by the conference members and messages matched with other user keywords and conference subjects, wherein the priority of the messages customized by the conference members is the highest.
In addition, the conference message server starts to rearrange the playing time of each message according to the following rules:
1. and ordering the messages customized by the user according to the time information in the message database.
2. The playing time of the subject message is randomly selected by the system after the user customizes the message.
Step 109, when the conference formally starts, the conference message server starts a timer, messages are played in sequence according to the starting time of playing the messages in the message playing list, if the message 1 is not played, the playing time of the message 2 is up, and the playing time of the message 2 is delayed.
The present embodiment integrates the solutions of the above-mentioned preferred embodiments, realizes the processing of the member messages and the subject messages, and provides a better playing order.
