Problems solved by technology

However, compared with the fixed Internet, the transmission rate of the mobile Internet still has a large gap, because the wireless bandwidth / link quality of the wireless network varies greatly, so it is difficult to simply transplant the P2P application in the fixed Internet to the mobile Internet environment middle

Embodiment approach

[0041] Due to the relatively large volatility of the mobile network, when the network is congested, if data requests are sent continuously, it will lead to more congestion of the network, and even cause the network to collapse. For TCP, it has its own congestion control process, but for UDP transmission, if congestion control is not considered, it is difficult to deal with the situation of relatively large network jitter. To solve this problem, the present invention proposes a congestion control scheme suitable for P2P streaming media in combination with the characteristics of P2P transmission.

[0042] In view of the fact that the data obtained by the P2P client is obtained by sending a data request in advance, rather than actively sent by the peer, so the adaptive adjustment of data transmission can be realized through the dynamic adjustment of the client's data request mechanism. When the network condition is relatively good, more requests can be sent, and when the network ...

Abstract

The invention relates to a transmission method and a player for a point-to-point mobile streaming media, which support a streaming media player to share and dispense the contents organized by an operator in a mobile communication network and comprise the following steps of: sending a fragment request periodically according to the requirement of playing the streaming media information, recording the time emitted by the fragment request and adding the time to a request list, receiving the response of the fragment request, deleting the fragment request that receives response from the request list, judging whether the fragment requests in the request list is overtime according to the time emitted by every fragment request periodically by an arranged timer; if not, turning to the step (1) and if so, deleting the overtime fragment request from the request list and re-dispensing a request and turning the step (2). The invention realizes the reliable transmission of the UDP by the improved upper layer application, and overcomes the defects that the UDP of the existing P2P transmits a large amount of residual messages and corresponding adjustment can not be carried out according to the fluctuation of the network condition.

Description

technical field [0001] The present invention relates to a mobile communication network, in particular to a transmission method and player for point-to-point mobile streaming media, in particular to a method for realizing reliable transmission of point-to-point mobile streaming media based on UDP (User Datagram Protocol, User Datagram Protocol) . Background technique [0002] In the traditional Internet, the currently popular P2P (Point to Point) application form covers video, voice, search, download and other applications, and has become the largest core application of the Internet. While the traditional Internet technology and applications are developing rapidly, the mobile Internet is not far behind. With the maturity of wireless communication technology, the scale of the mobile Internet is gradually growing. With the increase of wireless bandwidth, P2P has spontaneously moved into the mobile network. The proposal of the mobile P2P technology is to apply the idea of ​​th...
