In a preferred embodiment of the present invention, a portable communication apparatus (hereinafter, “the apparatus”) has a general mode and an anti-theft mode. The general mode and the anti-theft mode can be switched by user's operation. In the general mode, all functions of the apparatus are in a normal state. In the anti-theft mode, voice and message communication functions of the apparatus are in an anti-theft state, while the other functions are still in the normal state. A detailed implementing method of the preferred embodiment is described herein.
The apparatus 1 further defines a state value that indicates a current mode of the apparatus. For example, when the state value is “0”, it indicates the current mode of the apparatus 1 is the general mode, when the state value is “1”, it indicates the current mode of the apparatus 1 is the anti-theft mode.
The antenna 103 is provided for receiving an anti-theft mode signal transmitted from a wireless signal transmitting apparatus 2. The anti-theft mode signal is generated by the wireless signal transmitting apparatus 2 for response to a lock operation input of the user. When the anti-theft mode signal is received, the antenna 103 transmits the anti-theft mode signal to the CPU 104 through the first wireless communication unit 102. When the CPU 104 receives the anti-theft mode signal, the CPU 104 changes the state value from “0” to “1” and changes the mode of the apparatus 1 from the general mode to the anti-theft mode. In the anti-theft mode, the CPU 104 disables the voice and message communication functions. The CPU 104 signals the power control unit 106 to discontinue supplying power from the power source 105 to the voice receiving unit 107, suspends receiving voice signal from the voice signal receiving unit 107, or suspends sending the voice signals received from the voice receiving unit 107 to the general communication apparatus 4 to disable the voice communication function. To disable the message communication functions, the CPU 104 does not send the text file edited by users and stored in the temporary data storage 111. Furthermore, the anti-theft mode signal can also be generated and sent to the 104 by the input unit 101 after the lock operation input.
Once receiving an unlock signal, the CPU 104 changes the state value from “1” to “0”, and switches the current mode from the anti-theft mode to the general mode. That is, the CPU 104 enables the voice and message communication functions to revert to the activate state.
In addition, while in the anti-theft mode, when a voice communication instruction is received from the input unit 101, the CPU 104 sends a network connection instruction to establish a connection between the apparatus 1 and the general communication apparatus 4. Subsequently, the CPU 104 obtains a prerecorded voice file from the data storage 110 and transmits the prerecorded voice file to the second wireless communication unit 108, the second wireless communication unit 108 then sends the prerecorded voice file to the general communication apparatus 4 through the second antenna 109 and a communication network 3. The content of the prerecorded voice file can be “device has been stolen” or other content that alerts people that the user of the apparatus 1 is not the original owner of the apparatus 1.
When receiving a message communication instruction from the input unit 101, the CPU 104 obtains a prerecord message file from the data storage 110 instead of a message file stored in the temporary data storage 111. The prerecord message is then transmitted to the second wireless communication unit 108. The second wireless communication unit 108 sends the prerecord message to the portable communication apparatus 3 through the second antenna 109 and the communication network 4. The content of the prerecord message file can be “device has been stolen” or other content that alerts people that the holder of the apparatus 1 is not the original owner of the apparatus 1.
In step S201, the CPU 104 receives the anti-theft mode signal which transmitted from the wireless signal sending apparatus 2 or the input unit 101.
In step S202, the CPU 104 sets the apparatus 1 in the anti-theft mode according to the anti-theft mode signal.
In step S203, the CPU 104 receives the operational signal from the input unit 101.
In step S204, the CPU 104 determines the operational signal. If the operational signal is the voice operational signal, the procedure goes to procedure A. If the operation signal is the message operational signal, the procedure goes to procedure B. If the operation signal is the general operation signal, the procedure goes to procedure C.
In step S301, the CPU 104 sends the network connection instruction to establish a connection between the apparatus 1 and the general communication apparatus 4.
In step S302, the CPU 104 disables the voice communication function of the apparatus 1.
In step S303, the CPU 104 obtains the prerecorded voice file from the data storage 110 and then sends the prerecorded voice file to the general communication apparatus 4.
In step S401, the CPU 104 disables the message communication function.
In step S402, the CPU 104 obtains a prerecorded message file from the data storage 110.
In step S403, the CPU 104 sends the prerecorded message file to general communication apparatus 4.
In step S501, the CPU 104 implements the general instruction.
Although the present invention has been specifically described on the basis of a preferred embodiment, the invention is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the invention as recited in the claims and equivalents thereof.
