摘要： 3G is the abbreviation of 3rd Generation. Meaning the third generation mobile communicating technology. It is that the new generation of mobile communicating that being tied in wedlock multi-media between mobile communication system and internet technology. The test has discussed the research and application of distance learning based on 3G network, and has analyzed the main technology and the structure of the system. RTP (Real-time Transport Protocol)/RTCP (Real-time Transport Control Protocol) agreement storehouse is analyzed and designed in the paper. The transmission model of RTP (Real-time Transport Protocol)/RTCP (Real-time Transport Control Protocol) is designed, and the video image transmission and compression is discussed, at last the conclusion is given. It has no space limitation making use of 3G network to carry out distance learning.
