[0004] It can be seen from the above that in the prior art, the terminal needs to send a connection request message to each port in turn, and only when the terminal does not receive the connection response message returned by the port within the preset response time, the terminal sends a connection request message to the next port. Connection request messages, which in turn lead to a longer connection establishment time

The embodiment of the present invention provides a method and device for establishing a connection, which can be applied to a terminal in an instant messaging system. The instant messaging system also includes a server. Determine the current port to be connected, send a connection request message to the current port to be connected according to the port information of the current port to be connected, if the connection response message is not received within the first preset time length, return to execute according to the preset The connection sequence is a step of determining the current port to be connected from the port list, and the first preset duration is shorter than the preset response duration corresponding to the current port to be connected. Based on the above processing, after sending a connection request message to a certain port, if the connection response message is not received within the first preset time period, the terminal can send a connection request message to the next port without waiting for the preset response time period , which in turn can reduce the time to establish a connection.
Description
technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for establishing a connection. Background technique [0002] With the rapid development of Internet technologies, the functions of instant messaging (Instant Message, IM) services are also constantly enriched. In the IM service, a connection needs to be established between the terminal and the server, so that the terminal and the server can transmit service data. [0003] In the prior art, the connection between the terminal and the server is established through the following steps: when the terminal needs to establish a connection with the server, the terminal sends a port request message to the server. After receiving the port request message, the server sends the server's port list to the terminal, and the port list generally records port information of multiple ports. After obtaining the port list, the terminal can send a connection request message ...
