Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates to a method of sending instructions to a mobile phone, more particularly to a method of sending instructions from one transmitting device to mobile phones at a receiving end through short messages, enabling the mobile phones to execute the control information or instruction attached in the short message and be controlled by the transmitting device.  
      2. Description of the Related Art  
      Since our life has entered into a new era with booming telecommunication technologies, mobile phones have brought a hot wave to the telecommunication industry in the recent years. In early nineties, there were only about 1,000 mobile telecommunication users in the world; and a decade after, there are over 3.5 hundred million users now. The statistical data of the International Telecommunication Union (ITU) forecasted that there would be 5 hundred million mobile telecommunication users by the end of 2003, which would be about half of the quantity of the traditional city phones (about 9.5 hundred millions) by that time. For a conservative estimate, the number of mobile phones will go far beyond the number of city phone users after 2005, and the mobile phone will become a mainstream of telecommunications. The cellular mobile phone telecommunication is a revolutionary change to the telephone technology, which is no longer a node-to-node call, but is a person-to-person telecommunication. In addition, since the mobile phone is light and handy, easy-to-carry, reasonably priced, and capable of roaming over the network, mobile telecommunication become less restricted by time and space, and everyone can use it anywhere anytime. Therefore, mobile phones become a necessity of our telecommunications.  
      As the development of mobile phones proceeds up to now, it evolves from the original medium for transmitting voices to the present device concurrently having the function of transmitting information. As to the types of the data transmission, the first-generation mobile phones generally use an analog specification for the transmission, and the content of transmission is primarily voices. Both confidentiality and transparency are not as good. The second-generation mobile phones generally use a digital specification for the transmission. After a voice is digitized and coded, the digital codes are transmitted in packets, which greatly enhances the confidentially. However, with the arrival of the network era, the demand for digital webs and wireless webs is increasing, and mobile phones have been specified as an important integrated, controlled communication unit among independent products in the information appliance area. Till then, the demand for the data transmission of mobile phones greatly increases, and only the transmission and processing of the voice were taken into consideration at the early stage of establishing the second-generation mobile phone specification, but the data volume of pure digitized voice is not large. The transmission rate of 9.6 Kbps is sufficient for the second-generation mobile phones, but if it needs to process data containing images and files, then the transmission rate of the second-generation mobile phone is insufficient. Thus, the specifications for the second and half generation and the third generation were developed to cope with the huge data volume in this network era. The present transmission rate of the 2.5th generation specification reaches 115 kbps. With the great improvement on transmission rate, the requirements of transmission rate for static screens can be fulfilled, and the objectives of the wireless web under the established 2.5th generation transmission specification can be achieved finally. The establishment of the third-generation specification further raises the transmission rate to 2.4 Mbps, so that transmission of dynamic images can be implemented on a mobile phone. After the era of 3G has arrived, we can even watch televisions and movies or conduct person-to-person video conferencing through a mobile phone. The era of 3G will make our life more convenient, the access of information more timely, and the integration of communication, information, and network more closely. The structure of a mobile phone is divided into hardware and software, and the hardware is further divided into a baseband module, an intermediate frequency module, a radio frequency module and other components. The radio frequency module comprises a power amplifier (PA), a transmission receiver and a synthesizer; the intermediate frequency has an AD or DA signal converter; and the baseband module comprises a digital signal processor (DSP), a microcontroller (MCU) and a memory. Other components include a housing, a liquid crystal display (LCD), a printed circuit board (PCB), an antenna, a keypad, a speaker, a microphone, a subscriber identity module (SIM) and a battery.  
      In the basic operation of a mobile phone, an antenna receives a signal; a radio frequency module receives and amplifies the signal; an analog/digital (A/D) converter converts an analog signal into a digital signal; and finally the DSP of the baseband module processes the digital signal. In general, a mobile phone usually comes with a short message service (SMS) function, but such short message does not have the control function. In other words, the present mobile phone is unable to use a short message to control another mobile phone. Therefore, if there is a design that allows a short message of a mobile phone can be used to control another mobile phone, so that the mobile phone receiving the short message can execute the corresponding control instruction, such design not only brings tremendous convenience to the extensive consumers, but also provides a great contribution to the telecommunication technology.  
     SUMMARY OF THE INVENTION  
      With the previous profound introduction of the prior art, it is not difficult for us to see that if a mobile phone is not connected to another mobile phone with a cable, it is unable for a mobile phone to control another mobile phone. In other words, a mobile phone is unable to use a wireless method to control another mobile phone or execute a certain instruction.  
      In view of the foregoing shortcomings and the development trend of the present information technology, the inventor of the present invention conducted extensive researches and experiments, and finally developed a method of using short messages to send instructions to a mobile phone. Such ingenious idea of the invention is definitely a great contribution to the extensive consumers.  
      Since most of the common mobile phones in the market comes with the short message service function for sending or receiving short messages. Therefore, the primary objective of the present invention is to use the short message service method to send or receive a short message while attaching a control information or instruction, so that a mobile phone at a receiving end can execute the control information or instruction attached in the short message being received and be controlled by a device at a transmitting end.  
      The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
