Embodiment 1

[0021] Such as figure 1 Shown, based on the implementation method of the remote control software of TCP and UDP mixed protocol, described implementation method combines TCP agreement with UDP agreement, and UDP agreement sends various command messages to controlled end, comprises: shutting down, restarting, logging off, Commands such as mobile phone location acquisition, mobile phone keypad lock, and automatic screen capture. Data transmission is completed by the TCP protocol.

[0022] The TCP protocol is a connection-based protocol that provides reliable streaming services; while the UDP protocol is a connectionless protocol that provides data message services. Using the UDP protocol has low system resource overhead and fast transmission speed, but its reliability is not as good as that of the TCP protocol. Using the TCP / UDP hybrid protocol, it combines the security of TCP with the speed of UDP.

Embodiment 2

[0024] On the basis of Embodiment 1, the operation process of the implementation method described in this embodiment is as follows:

[0025] 1) When the remote controlled application is used, the control terminal program sends commands to the controlled program of the controlled terminal mobile phone through the UDP protocol, such as shutdown, restart, logout, mobile phone location acquisition, mobile phone keyboard lock, and automatic screen capture. The terminal verifies the credibility of the signal, sends the ID and allows the controlled signal to the control terminal;

[0026] 2) The control terminal sends ack and control signals, establishes a special remote service, and then uses various remote control functions to send remote control commands through this remote service to control the operation of various applications in the mobile phone of the controlled terminal.

Embodiment 3

[0028] On the basis of Embodiment 2, the controlled terminal described in this embodiment actively connects to the control terminal to make up for the defect that the TCP application cannot penetrate the intranet.

[0029] Example 3:

[0030] On the basis of Embodiment 2, the controlled terminal described in this embodiment performs port mapping on the router to the control terminal.

Abstract

The invention discloses a remote control software realization method based on a combined TCP and UDP protocol. According to the method, a TCP protocol and a UDP protocol are combined, various command messages are sent to a controlled end through the UDP protocol, and data transmission is accomplished through the TCP protocol. Through the method, reliable service is provided based on reliability of the TCP protocol; the UDP protocol is a connection-less protocol, data message service is provided, small system resource cost and rapid transmission speed can be realized through utilizing the UDP protocol; safety of the UDP protocol and rapidity of the TCP protocol are combined through utilizing the combined TCP and UDP protocol.

Description

technical field [0001] The invention relates to the technical field of computer network communication, in particular to a method for realizing remote control software based on a mixed protocol of TCP and UDP. Background technique [0002] (1) TCP protocol [0003] TCP (TransmissionControlProtocol Transmission Control Protocol) is a connection-oriented, reliable, byte stream-based transport layer communication protocol. The advantage of the remote control software of the TCP protocol is stability and high connection success rate; the disadvantage is that one of the two parties must have a public IP (or be in the same intranet), otherwise port mapping needs to be done on the router. 98% of the remote control software on the Internet use the TCP protocol to achieve remote control (including the above-mentioned models). The advantages of the remote control software using the TCP protocol are stability and high connection success rate; the disadvantage is that both parties must ...
