Embodiment Construction

[0028] refer to figure 2 As shown, the communication system of the present invention includes a plurality of communication devices and a communication network connected to the communication devices, an application server and an assistance server (not shown in the figure) connected to the communication network, and data is transmitted between each device through the communication network. The assisting server caches service data and is used to assist the data source in transmitting data to the communication device receiving the data. The application server is used to control the establishment of P2P connection and data forwarding between communication devices. Terminals can also directly establish a connection and transmit data without going through an application server.

[0029] After the invention assists the server to know the data transmission request of the communication device, according to the content of the transmitted data, if it is found that there are more sources...

Abstract

The method includes steps: communication equipment in network initiates request for transmitting data; after obtaining the said request, assistance server in network determines whether data relevant to the request are stored; when assistance server has stored relevant data, and assistance server is needed to transfer data, connection between assistance server and communication equipment of receiving data is built, and assistance server transfers data in assistance. The invention also discloses a communication system.

Description

technical field [0001] The invention relates to data transmission technology in the field of communication and computer, in particular to a method and system for assisting data transmission. Background technique [0002] With the development of the Internet and mobile networks, P2P (Peer to Peer) content sharing between users based on the Internet or mobile networks is becoming more and more frequent. The P2P data transmission method is more and more popular among users due to its obvious effects in terms of content quantity and speed. However, in some cases, such as mobile networks with high network communication costs, P2P data transmission is relatively expensive because it needs to occupy two bandwidths of uplink and downlink of the mobile network to transmit one piece of content. Moreover, in some commercial fields, P2P content delivery cannot be guaranteed in terms of service quality, and some technologies are urgently needed to solve such problems. [0003] The core...
