Mobile Terminal and Method and System for Establishing IP Connection between Mobile Terminals

A system for establishing an Internet Protocol connection between mobile terminals, the system comprising:

• a request terminal, used to start an end-to-end program after connecting to a wireless network, and send a request short message to a called terminal;
• and also used to perform IP-based data interaction with the called terminal when the end-to-end program of the request terminal monitors a network connection request;
• a called terminal, used to connect to the wireless network when detecting that the received short message is a request short message and the user accepts the request, and to display the end-to-end program in the request short message to the user, after the user starts the end-to-end program and inputs an IP address of the request terminal, the called terminal's own end-to-end program sending the network connection request to the request terminal;
• a wireless network, used to provide a data interaction platform for the request terminal and the called terminal.

A mobile terminal for establishing an Internet Protocol connection, when working as a request terminal, the mobile terminal comprising:

• a first Internet accessing module, used to connecting to a wireless network before starting an end-to-end program;
• a first list creating module, used to store the end-to-end program thereof in a list in advance in accordance with a program name, a path, and a version number;
• a request module, used to send a request short message to a specified terminal when starting the end-to-end program;
• a first short message receiving module, used to receive a short message and display text of the short message;
• a first data interacting module, used to perform IP-based data interaction with the specified terminal when the end-to-end program thereof monitors a network connection request;
• when working as a called terminal, the mobile terminal comprising:
• a second Internet accessing module, used to connecting to a wireless network before starting an end-to-end program;
• a second list creating module, used to create an end-to-end program list and store all end-to-end programs thereof in a list in advance in accordance with the program name, the path, and the version number;
• a second short message receiving module, used to, after detecting a request short message, display the text of the request short message, prompt the user to accept the request, and, when an accepting button is pressed, to notify the second Internet accessing module and the parsing module;
• a second data interacting module, used to send a network connection request via the end-to-end program to a terminal sending the request short message after the user starts the end-to-end program displayed by a searching module and inputs an IP address in the request short message;
• a parsing module, used to parse the text of the received request short message to get the program name and send the program name to a searching module;
• a searching module, used to search the end-to-end program in the end-to-end program list thereof according to the program name, and when the end-to-end program is searched out, display the end-to-end program to the user;
• otherwise, prompt the user to search the end-to-end program manually.
