Data transmission method and system

Abstract

The present invention discloses a data transmission method and a system. The method includes: sending a connection request by a client terminal; establishing a targeted session with the client terminal; sending by a proxy server the targeted transmission data to the client terminal through the targeted session; when the first connection is detected to have been interrupted by the client terminal, establishing a connection with the proxy server again and sending a data request to the proxy server; and when the proxy server receives the data request, resuming the targeted transmission data to the client terminal through the targeted session from the data that the client terminal does not receive for the first connection interruption. With the technical schemes of the present invention, the fluency and continuity of the client terminal can be minimized when the network is unstable and disconnected, so that after the client terminal is reconnected after the disconnection, the targeted transmission data that have yet to be received can be obtained for maintaining the fluency and continuity of operations as much as possible, without repeating the previous operations.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and system. Background technique [0002] At present, the biggest problem encountered by the client when performing games and other operations is network instability, such as frequent Wifi signal loss, switching between different Wifis, switching of base stations while moving, switching between Wifi and mobile data network 3G / 4G However, once the problem of network instability occurs, the client will be disconnected with a high probability, causing the game and other operations to be interrupted. After the client is disconnected, the server of the client will not continue to send data to the client. Therefore, even if the client re-establishes a connection with the server, it often cannot continue the game and other operations on the original basis and has to repeat the original operation again, which undoubtedly seriously affects the flu...

Problems solved by technology

[0002] At present, the biggest problem encountered by the client when performing games and other operations is network instability, such as frequent Wifi signal loss, switching between different Wifis, switching of base stations while moving, switching between Wifi and mobile data network 3G / 4G However, once the problem of network instability occurs, the client will be disconnected with a high probability, causing the game and other operations to be interrupted. After the client is disconnected, the server of the client will not continue to send data to the client. Therefore, even if the client re-establishes a connection with the server, it often cannot continue the game and other operations on the original basis and has to repeat the original operation again, which undoubtedly seriously affects the fluency of the client operation. and continuity, thereby degrading the user experience

[0003] For this reason, the solution that adopts in the related art is usually to use VPN (Virtual Private Network, virtual private network) agreement to support disconnection reconnection etc., but VPN needs very complicated setting when using, and VPN is the proxy of equipment level simultaneously, The cost is relatively high. Therefore, due to the difficulty and cost of disconnection and reconnection methods in related technologies, fewer manufacturers have actually implemented them, so that when the client is performing operations such as games, once the network is unstable, it still needs to be connected. There will be a high probability of disconnection, and the fluency and continuity of client operations will be greatly affected, which will seriously affect the user experience
