Embodiment
Based on the RTP transmission method in XML tunnel, utilize the existing framework of IMS, media negotiation goes out the xml tunnel, utilizes the xml tunnel that various RTP medium are passed through again.Specifically may further comprise the steps:
1. the media negotiation extended attribute is supported the tunnel RTP transmission of xml, comprises information such as host-host protocol, port and address;
2. when needs carry out tunnel transmission, various RTP medium are packed according to the xml form of standard, and transmit according to the information of consulting; As consult to come the transmission tone video with the http agreement, after at this moment need packing, send with the http agreement to the audio frequency and video that will transmit;
3. far-end (the other side's logical server) is handled: such as professional uses such as the prompt tones of imparting knowledge to students, put; The address of server is directly indicated in the xml tunnel; Use remote processor; Need not carry concrete medium, save resource, even make that local terminal is not that media server also can be brought into play very large space on the net;
4. local terminal (user's oneself logical server) is handled: such as professional uses such as faxes, local terminal can adopt xml to carry method transmission such as picture text, and far-end is directly printed, and local terminal is handled the functions of the equipments requirement of the far-end that weakened.
Media negotiation adopts the mechanism of request-reply to hold consultation all in accordance with international each standard.Result to after consulting can also alter course and upgrade, and all according to international standard, the present invention only is by standard the expansion information that the xml tunnel negotiation is provided, processing method and media negotiation basically identical.After consulting successfully, open the xml tunnel and supply various medium to pass through, the port that no longer all will open oneself as every kind of traditional medium transmits.
As shown in Figure 1, media consultation process with traditional consensus, after being accompanied by request and replying, if the xml tunnel transmission is all supported at two ends, is then opened the tunnel, and follow-up RTP medium are walked the tunnel turnover.
As shown in Figure 2, all can pass through the xml tunnel transmission for various RTP medium, walk the IP network transmission according to the agreement of consulting then; Collect the digits inside and outside audio frequency, video, fax, message, the band and professional indication all can be passed through the xml tunnel transmission.It is extensively to have embodied the xml tunnel scope of application, and the reader can be according to the Demand Design rtp content of oneself.
