Data transmission method and system based on mobile terminal and mobile terminal

Abstract

The invention provides a data transmission method and system based on a mobile terminal and a mobile terminal. The data transmission method comprises the following steps: a source mobile terminal transmits a service request message, which contains the IP (Internet Protocol) address of the source mobile terminal, to an objective mobile terminal through a mobile switch network, and if a TCP (Transmission Control Protocol)/IP connection request transmitted by the object mobile terminal, which adopts an IP address per se, to the source mobile terminal is received, the source mobile terminal returns the TCP/IP connection request to the objective mobile terminal, and service data in communication interaction is transmitted by point-point IP routing, which is established by the source mobile terminal and the objective mobile terminal. The data transmission method and system based on the mobile terminal and the mobile terminal, provided by the invention, can achieve the communication interaction between the source mobile terminal and the objective mobile terminal through the point-point IP routing so as to improve the distance between mobile terminals and reduce the power consumption of mobile terminals, and is conducive to the transmission of large quantities of data.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a mobile terminal-based data transmission method and system and a mobile terminal. Background technique [0002] With the development of communication technology, mobile terminals are becoming more and more intelligent, with more and more functions such as taking pictures, video recordings, and downloading music and videos from the Internet. The basic function of SMS, the demand for sharing photos, music and videos between users is getting stronger and stronger. [0003] In the prior art, service data transmission can be completed between mobile terminals through bluetooth or infrared transmission. However, because Bluetooth supports mobile terminal communication, the distance is generally within 10m; infrared supports mobile terminal communication. The transmission distance of the transmission is limited. Furthermore, since the power co...

Problems solved by technology

However, because Bluetooth supports mobile terminal communication, the distance is generally within 10m; infrared supports mobile terminal communication. The transmission distance of the transmission is limited

Furthermore, since the power consumption of bluetooth or infrared transmission is also very large, and the battery capacity of the mobile terminal is limited, the transmission capacity of data transmission using bluetooth or infrared is also limited, and it is not suitable for transmitting large quantities of data.

To sum up, the application of Bluetooth or infrared transmission between mobile terminals to complete data transmission has certain limitations.
