A method and system for quickly setting a port number

Abstract

The invention discloses a method and system for quickly setting a port number. By detecting that a process calls a port number generation function, it is judged whether there is a port number corresponding to the process in the memory, and if the port number is not occupied, the port number is used; In addition, the port number generation function is called to generate the port number; an area is reserved in the memory for storing the port number of each process. When a process is executed for the first time, the port number is generated by the port number generation function, and the port is judged. If it is occupied, continue to call the port number generation function until an unoccupied port number is generated; use the port number and save the port number of the process; so that when there is an application layer that needs to communicate with the remote When the server establishes a connection, the port number can be quickly set, instead of calling the port number generation function to generate the port number as in the current technology, thereby improving the system execution efficiency.

Description

technical field [0001] The invention relates to the application field of mobile terminals, in particular to a method and system for quickly setting port numbers. Background technique [0002] At present, more and more mobile terminals are using the network. In the computer network reference model, the transport layer realizes end-to-end data transmission. The data is redistributed to each process specified by the port number. In the application layer, there are multiple processes using the network for data transmission. When the transport layer receives a data packet, it delivers the data to the process using the port number according to the port number in the data packet. [0003] In the prior art, for a client (such as a mobile terminal), when a user process establishes a connection with a server, it needs to first generate a port number to mark the process, and then send the port number to the server that needs to establish a connection; here , each time a connection is...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a method and system for quickly setting the port number, aiming at solving the problem of quickly setting the port number when the application layer needs to establish a connection with the remote server
