## Background
TECHNICAL FIELD
A certain embodiment of the invention relates to a system for household appliance control, and in particular, to a system and method for remote household appliance control based on a mobile communication network.
BACKGROUND ART
Recently, with the improvement of the standard of living of people, a large number of household appliances enter people's life. Meanwhile, with the rapid development of the mobile network, more and more people possess mobile phones. Thus, there arises a demand of controlling the household appliance using the mobile phone, and meanwhile it is required that the manner for remote interaction be simple, convenient and reliable.
The traditional system for remote household appliance control is mainly implemented by means of short message, but it has the following problems:
1) the security is poor;
2) the real-time performance is poor. The short message is transmitted in the store-and-forward manner, so the short message may be caused to fail to reach the destination household appliance in time due to reasons such as network congestion;
3) devices like GSM (Global System for Mobile Communications) MODEM need to be configured to perform control using the short message, so the costs are high;
4) the interaction is poor, and the user's experience is not friendly enough.
The Unstructured Supplementary Service Data (USSD) service is a novel interaction session data service that is real-time online and based on the global mobile communication network. This service is currently mature in technology, the data are transmitted using the signaling channel of the network based on the SIM (Subscriber Identity Module) card, and it is connection-oriented, so the reliability is high.
Both USSD and Short Messaging Service (SMS) are transmitted through the signaling channel of the network. The difference is that the short message adopts the store-and-forward manner, while USSD adopts the session-oriented manner. When a user visits a USSD service, the session path keeps connected until the session is over. In addition, since a transmission USSD string transparent path directly reaching an external service node through the HLR (Home Location Register) is provided, the user can also visit the service node outside the GSM network.
In a word, the USSD has the following features:
(1) Rapid. In the interactive application, since it only needs to establish the connection once, the delay for establishing the signaling connection for multiple times is reduced, the response time for one round is shorter than that of short message, and can be one seventh of the corresponding time for short message at most.
(2) Convenient. The user does not need to perform stepped menu selection, but directly enters the USSD command string.
(3) Support roaming. Each command of USSD passes through the HLR, so it operates in the same way as based on the USSD service when the user is roaming.
(4) Wide applicability. The USSD can be operated on all current mobile phones.
(5) Strong functions. Services can be provided in the session manner and information service menu manner.
3GPP (Third Generation Partnership Project) also includes the description on USSD, and both WCDMA (Wideband Code Division Multiple Access) and TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) comply with the 3GPP standards, that is, the USSD technology can be widely supported in GSM, WCDMA and TD-SCDMA networks.
Infrared remote control is a remote control means that is used most widely at present, and this technology transmits a remote control instruction using near-infrared light with a wavelength of 0.76 um-1.5 um, and has a high transmission efficiency and high reliability.

Step two, the user logs in the web page provided by the control manager, configures the USSD menu of his home remote control controller, the control manager records the corresponding relationship between the menu and the identification information of the remote control controller and the number information of the mobile terminal; in addition, the remote control controller, in conjunction with the infrared way transmitter with the learning function provided thereon, learns the infrared code types of the keys on the matched remote control of the household appliance, and sends the code types to the control manager to record the second corresponding relationship between the code type and the corresponding operation object configured by the user, operation act and the identification information of the remote control controller.
If the control manager provides a human-machine interaction interface, taking the WEB manner as an example, the user selects adding a household appliance (fore example the TV) after logging in, configures information of its operable act, such as switching on, switching off, etc., and a recording button is provided on the WEB during configuration, the user, after clicking the button, can learn the code type corresponding to performing the operation act on the household appliance through the remote control controller, and after completion of learning, the remote control controller sends the learned code type to the control manager, the control manager prompts through the WEB that code type learning is successful, after recording the corresponding relationship between the code type and the identification information of the remote control controller, the operation object and the operation act.
Step three, the controller initiates, through a mobile phone, a USSD session request to establish a connection with the remote control access device, and then the remote control access device forwards the number information of the above mobile phone (possibly along with the identification information of the remote control controller) to the control manager, the control manager searches the corresponding relationship configured thereon for the USSD menu corresponding to the number information, and if there is the USSD menu, the next step is executed; furthermore, if the control manager receives the identification information of the remote control controller, it firstly judges whether the identification information of the remote control controller corresponds to the number information of the mobile terminal according to the first corresponding relationship, and if yes, searches for the corresponding menu; otherwise, prompts the user of control failure, ending.
Step four, the control manager sends the corresponding USSD menu to the user's mobile phone through the remote control access device, and starts the USSD session with the mobile phone through the remote control access device.
Step five, the user interacts with the control manager through the USSD menu.
Step six, after completion of interaction, the control manager records this interaction to the system log, and meanwhile transmits the corresponding infrared code type searched out according to the above first corresponding relationship to the corresponding remote control controller according to the received content of the USSD session related to performing the operation act on the household appliance sent from the mobile terminal.
If the first corresponding relationship further comprises time information corresponding to performing the operation act on each controlled household appliance, then after receiving the content of the USSD session related to performing an operation act on a household appliance sent from the mobile terminal, whether a current time meets the time information corresponding to initiating the operation act on the household appliance involved in the content of the session is firstly judged, and if so, the corresponding infrared code type searched out according to the above first corresponding relationship is sent to the corresponding remote control controller; otherwise, the mobile terminal is prompted by the remote control access device that the household appliance cannot be controlled at this moment, ending.
Step seven, the remote control controller transmits the infrared signal according to the code type sent from the control manager to control the corresponding household appliance.
In order to make the example more specific, the USSD service access code of the remote control access device is set to be 125, the number of the remote control controller is 10, and the mobile phone number of the controller is 13966667724.
As shown in FIG. 2, the controlling flow of the system for remote household appliance control based on a mobile communication network is as follows, where a TV switching-on control is taken as an example:
Step 1, the control system administrator logs in the control manager, enters the related information of the remote control controller, and allocates a number (i.e., the identification information of the remote control controller) and a user account that can configure the information of the remote control controller.
Step 2, the user logs in the control manager using the account allocated by the control system administrator, configures the USSD menu for the remote control controller, and the electrical appliance information displayed in the USSD menu configured by the user in the control manager is: TV, DVD, air conditioner, and the control acts configured for TV are: switch on, switch off, volume up, volume down.
Meanwhile, the remote control code type of the corresponding key on the TV remote control is learned through the infrared ray transmitter in the remote control controller and is recorded in the control manager when the control act is configured.
Then, the user configures the time segment when the control can be received, and the number of the bound mobile phone that can perform control is 13966667724.
Step 3, the controller initiates a USSD session request through the mobile phone, and the content of the message is *125#10#, and the calling number is the 13966667724 that has been configured by the user in the control manager.
Step 4, the mobile communication module of the remote control access device sends the message to the control manager after receiving the request.
Step 5, the control manager judges whether the user number is correct or not; if it is correct, step 6 is executed, otherwise, end.
Step 6, the control manager acquires from the message that the remote control controller of number 10 is to be controlled, and the USSD first-level menu configured by the user is issued, and the controller's mobile phone displays the following similar menu:
Well to enter the household appliance control system, the number of the controller is 10
Please select the household appliance to be controlled
1. Television
2. DVD
3. Air conditioner
1 is selected in the user feedback, and the Television is to be controlled, and the control manager issues the second-level menu:
Well to enter the household appliance control system, the number of the controller is 10
Please select the control act:
1. Switch on
2. Switch off
3. Volume up
4. Volume down
1 is selected in the user feedback to perform switch-on control on the Television, and the session ends.
If the mobile phone number initiating the session is not the bound number configured in the control manager, the control manager will not issue the control menu, and can send a USSD message to the user's mobile phone to prompt that the number could not initiate the control.
Step 7, after the session ends, the control manager judges, according to the time when the user initiates the control, whether the time is within the time segment configured by the user during which the remote control controller can accept control, and if yes, step 8 is executed, otherwise, step 9 is executed.
Step 8, the control manager forwards to the remote control controller the infrared code type for controlling the switch-on act of the Television that is entered into the control manager by the user in advance; proceed to step 10.
Step 9, the control manager can send a USSD message to the user's mobile phone to prompt that the control cannot be initiated during this time segment; end.
Step 10, the remote control controller receives the infrared signal code type sent from the control manager, and triggers the infrared ray transmitter according to the code type to transmit an infrared control signal and performs switch-on control on the Television.
After step 10, there may be step 11: the control management system records the log.
A person having ordinary skill in the art can appreciate that all of part of the steps of the above method may be implemented by instructing related hardware with a program, which may be stored in a computer-readable medium, such as a read-only memory, a magnetic disk or an optical disk.
