Remote control method, system and terminal device

Abstract

This invention discloses a remote control method, a system and terminal equipment, in which, if a network side receives a control message sent to a second terminal carried in the signaling from a first terminal device, it carries the control message in the signaling to be sent to the second terminal device and sends it to the device and instructs the device to trigger a related remote control based on said control message, which can be carried in the signaling in the process when the first terminal device asks to set up call with the second terminal device.

Description

technical field [0001] The invention mainly relates to the field of wireless communication, in particular to remote control technology. Background technique [0002] Along with the rise of the digital home, a Machine-to-Machine (M2M for short) technology becomes popular. At present, M2M focuses on machine-to-machine wireless communication, and there are three ways: machine-to-machine, machine-to-mobile terminal (for remote monitoring by users), and mobile terminal-to-machine (for remote control by users). [0003] M2M technology is mainly used in the following scenarios: [0004] (1) Control, regulation and monitoring of white goods and other equipment, such as microwave ovens, washing machines, lights, electric curtains, burglar alarms, automatic door smoke detectors, harmful gas detection devices, temperature and humidity controllers, air volume regulators , various manual switches and remote controls, etc. [0005] (2) Communicate information channels between black hom...

AI Technical Summary

Problems solved by technology

[0009] However, the inventors of the present invention have found that the above-mentioned method of controlling remote devices through short messages has the following problems: 1), short messages are easily congested and lost, and can not be sent when the business is relatively busy, as shown in Figure 5 Poor bidirectionality and timeliness may lead to control failure, making it impossible for users to control remote devices in time

2) It is necessary to install a short message receiving device on the remote device, and the price of the short message receiving device is relatively expensive

[0013] 1) The network is easy to be blocked, and the timeliness is poor, which will lead to control failure, as shown in Figure 8

[0014] 2) GPRS receiving equipment is more expensive

[0018] 1) For ordinary users, if there is no support from the operator, the smart device cannot be used for voice prompts, and the number corresponding to the operation needs to be memorized, and it is easy to issue wrong commands; even if the intelligent network device is used for voice prompts, due to the long voice prompt time, It will waste a lot of time for users, and some voice prompts have multiple branches, requiring users to select keys, making it very inconvenient for users to use

[0019] 2) There is a charging problem in the voice channel. Repeated control for a period of time (such as controlling the repeated closing and opening of the exhaust fan) will cost a lot

[0020] 3) There is no fallback mechanism, and it is also easy to misuse

[0021] 4) It needs to occupy the voice channel, which consumes a lot of network resources
