3. PREAMBLE TO THE DESCRIPTION:
The following specification describes the invention and the manner in which it is to
be performed.

Field of Invention:
The present invention relates to an appliance controlling mobile phone. More specifically, the present invention relates to establishing appliance control over an infra-red communication network between the said mobile phone and the appliance without engaging additional paraphernalia.
Background of Invention:
In recent years, there has been much advancement in the field of mobile operations and functions. It is natural that these advancements are incorporated in day-to-day living and help build a mobile environment to remotely access appliances over networks by establishing communication between the appliances and the mobile devices.
India is a developing country and optimal management of electricity: consumption and conservation are of paramount importance in such a country. India, being vast as it is, is still largely considered as a country having tropical climate with harsh to extreme heat temperatures in summers. Hence appliances like air-conditioners are now widely used in the country.
It is observed, that the electricity consumption by air-conditioners is still a matter of concern. Users keep them switched on after use in fear of letting the room get warmer or at times, may even forget to switch them off at all after they have left the room. This leads to exaggerated wastage of electricity. Hence, there is need of a device that promotes a remote control operation of such heavy electricity consuming devices.
There are systems available that have multi-appliance control functions. But one has to incur additional expenses to set-up the entire system machinery with its sensors, monitors, computing setup and other such paraphernalia. For consumers, who use air-conditioners as a necessity instead of a luxury, it becomes over burdening to bear such huge costs for such a setup and incur additional costs for working and maintain them, for just one appliance. Moreover, such systems need periodical servicing, as failure of any single

transmission and/or monitoring component can render the system redundant for proper functioning.
A US application, US 2004249925, discloses a method and system for 'remotely controlling appliances using a wireless terminal' wherein, said method relates to remotely controlling appliances using a set-top-box with a built-in wireless function such as 802.1 lb/g/a for a WLAN (Wireless Local Area Network) or a wireless terminal such as a wireless smartphone, PDA or a VoIP (Voice Over Internet Protocol) phone. The above system becomes complicated to install and service by a layman user as it involves configuration and setting number of IP addresses for each of the components in the system. The communication message including the control data is burdened by inclusion of multiple details, hence creating additional processing overheads in the overall system. Such a technology can enjoy very limited popularity in developing countries since devices such as set-top-boxes and VoIP phones can not been extended to the masses easily without incurring heavy costs and the overall method becomes complicated to use and troubleshoot for the largely untrained end users.
Some published papers suggest implementing an exhaustive system comprising multiple sensors, various networking components, and connecting appliances to these components though wired media. Such a system is computerised and provided with user interfaces simulating remote control functions on any PDA, smartphone and the likes as an additional application. Operating an external application on complicated phones may introduce processing burdens and may affect the efficiency of the overall system.
Such drawbacks of the prior art generate the need for a wireless system or a device that has a simple, minimal setup, inbuilt operations and minimal investment and operational costs and which can be popularized without cost or technological complications.
Summary of Invention:
A wireless network comprising a mobile phone with an integrated appliance control feature is disclosed herein.

The present invention comprises of a wireless network for remotely controlling configured appliances using an appliance control mobile phone via text messages sent from a user's regular mobile phone. An aspect of the present invention includes a functionality to switch an Air conditioner on or off on user's request.

Detailed Description of Invention:
Affordable and easy use of mobile phones on a day-to-day basis has made it a favoured choice from amongst various media for remote controlled applications. It is easily operable and its use is understood well by the masses in general. The present invention thus embodies a novel, simple yet effective approach to implement high-end technology in daily used devices.
The present invention is a wireless network for remotely controlling appliances by an appliance control mobile phone, with inbuilt remote control functioning, via text messages sent on the said phone from any regular GSM/CDMA mobile phone by a user.
In an embodiment, the appliance control mobile phone comprises a chip, for remotely controlling appliances, that is embedded with communication protocols, procedures and databases. It is interfaced with the appliance control mobile phone's main chip of the General Purpose Input Output (GPIO) port to command the trigger for the remote control operation. All procedures, algorithms and data related to remote controlling of appliances are stored on this remotely controlling chip. The appliance control mobile phone establishes contact and executes controlling action over various appliances through this remotely controlling chip over an infrared (IR) communication channel. The remote controlling chip maintains a separate table containing various data about appliance identification codes, instruction codes and IR codes. Instructions are stored in a separate

memory chip. Data index is maintained external to the table. The index stores commands, data, instructions to meet the path of the virtual remote control device to achieve accurate address and set of functions.
The said appliance control mobile phone is placed on a stand/ holder in front of an appliance to be controlled in a clear range, without any obstruction. A user may use any GSM/CDMA mobile phone to send a text message, containing a specified string of instruction regarding controlling said, appliance, to the said appliance control mobile phone. On receipt of a text message, the appliance control mobile takes the following actions:
• Contents of the text message are parsed for instructions to control appliance, else simply displays it as a regular message.
• On finding instructions, the contained instruction is validated.
• The validated instruction is then forwarded on to the corresponding appliance, which then executes it and sends feed back to the appliance control mobile phone.
The appliance control mobile phone then sends the specified IR code of the instruction to the appliance which then executes the instruction upon receiving the respective commands.

(2) denotes stored instructions meant to be performed on the air conditioner(AC). (3) houses instruction regarding infrared communication and instruction management. (4) includes infra-red instruction codes
Fig 2 illustrates functional overview of the appliance control mobile phone. A user may send an SMS including the instruction for an AC over a GSM/ CDMA mobile network to said appliance control mobile phone. The said appliance control mobile phone validates the SMS for a proper format of instruction before further processing. If the SMS includes an AC instruction, it is transmitted to the AC over the infra-red channel, else the mobile prompts for a simple SMS receipt indication. The processing controller in the AC executes the instruction received via SMS and provides a confirmation/acknowledgement

to the appliance control mobile phone. This can then be forwarded to the user's mobile phone.
In its present embodiment, the present invention serves a great purpose in energy conservation and efficiency while controlling an AC. While the AC is in use and should the consumer leave the premise without switching it off, the consumer can simply send an instruction in an SMS to switch the AC off to the present appliance control mobile phone. Similarly, in summer days, when the ambient temperatures keep soaring, one can reduce the premise temperatures beforehand by sending an instruction over an SMS, the AC can be switched on before one reaches the premise. Thus, the appliance control mobile phone brings ease and comfort with convenience of a single SMS.
The appliance control mobile phone analyses to check if the SMS is a remote control SMS. In case, it is not a remote control SMS, the received SMS is displayed as conventional SMS. If the received SMS is a remote control SMS, comparative analysis is performed on the contents of the message and related instruction to switch ON or switch OFF the air conditioner and subsequently delete the message from in box. For a shutdown operation in an AC:
• The pre-set AC function group is obtained.
• The shutdown instruction is sent to the appliance over IR channel and executed by , the appliance and,

• Feedback is sent via SMS to the appliance control mobile phone. Similarly, for a switch on operation in an AC:
• The pre-set AC function group is obtained.

• The switch on instruction is sent to the appliance over IR channel and executed by the appliance and,
• Feedback is sent to the user via SMS by the appliance control mobile phone.
If the placement of the appliance control mobile phone is placed in a clear, inline and obstruction free direction towards the appliance to be controlled, the operation is successful else it fails.
