FIG. 3  is a schematic diagram of a process  30  according to an embodiment of the present invention. The process  30  is applied to the wireless communication system  10  capable of sharing system resource, and comprises the following steps: 
         [0015]    STEP  300 : Start. 
         [0016]    STEP  302 : The wireless communication device  100  is coupled to the interface  200  of an electronic device ED_a of the electronic devices ED_ 1  ˜ED_n.

         [0019]    STEP  308 : End. 
         [0020]    According to the process  30 , when the wireless communication device  100  is coupled to the electronic device ED_a, the electronic device ED_a can perform the first wireless communication function of the wireless communication device  100 ; meanwhile, the electronic device ED_b can connect to the electronic device ED_a via the wireless communication unit  204 , and perform the first communication function via the electronic device ED_a. In other words, in the wireless communication system  10 , the electronic device ED 1 ˜ED_n are capable of sharing the wireless communication function of the wireless communication device  100 . Therefore, the present invention can save system resource and increase the convenience. 
         [0021]    In the present invention, the wireless communication device  100  connects to an electronic device by means of plug and play, which allows the electronic device to perform the first communication function of the wireless communication device  100 , and the other electronic devices can connect to the electronic device via the second wireless communication function to perform the first wireless communication function. Note that,  FIG. 1  is the schematic diagram of the preferred embodiment of the present invention, and those skilled in the art can make modifications and alterations accordingly. For example, the number of the electronic devices ED_ 1 ˜ED_n is not limited to any specific quantity as long as it is greater than 1, and the electronic devices ED_ 1 ˜ED_n can be realized by often seen electronic products, like notebook computer, mobile phone, PDA, etc. 
         [0022]    Please refer to  FIG. 4 .  FIG. 4  is a schematic diagram of a wireless communication system  40  according to an embodiment of the present invention. The wireless communication system  40  is a special embodiment of the wireless communication system  10 , and comprises a wireless communication device  400 , a notebook computer  406  and an audio and video (AV) processing device  408 . The wireless communication device  400  comprises a mobile communication unit  402  and a wireless network connection unit  404  to perform the mobile communication function and the wireless network connection function, respectively. The notebook computer  406  and the AV processing device  408  can perform the plug and play to the wireless communication device  400  to perform the mobile communication function or the wireless network connection function. Simultaneously, the notebook computer  406  and the AV processing device  408  can establish the wireless connection via the bluetooth communication function. 
         [0023]    To demonstrate the operation of the wireless communication system  40  more clearly, first, if the wireless communication device  400  couples to the notebook computer  406 , then the notebook computer  406  can connect to the wireless communication connection unit  404  via the mobile communication unit  402  and the wireless communication connection unit  404 . Meanwhile, the AV processing unit  408  and the notebook computer  406  can establish the wireless connection to perform the mobile communication function or the wireless network connection function via the notebook computer  406 . For example, if the notebook computer  406  performs the mobile communication function via the mobile communication unit  402 , the function of the notebook computer  406  can be analogous to a mobile phone, and the AV processing device  408  can behave like a handset. Under this condition, if the AV processing device  408  has better portability, the user can put the notebook computer  406  in the backpack or the desk drawer while the user can make a phone call via the AV processing device  408 . Similarly, if the notebook computer  406  performs the wireless network connection function via the wireless network connection unit  404 , since the video and audio processing device  408  already makes wireless connection with the notebook computer  406 , the AV processing device  408  can access wireless network via the notebook computer  406 . Under this condition, if the AV processing device  408  has better portability, the user can put the notebook computer  406  in the backpack or the desk drawer while the user can browse Internet or send/receive emails via the AV processing device  408 . 
         [0024]    On the contrary, if the wireless communication device  400  is coupled to the AV processing device  408 , then the AV processing device  408  can perform the mobile communication function or wireless network connection function via the mobile communication unit  402  and the wireless network connection unit  404 . Meanwhile, the notebook computer  406  can make a wireless connection with the AV processing device  408 , and perform mobile communication function or wireless network connection function via the AV processing device  408 . For example, if the AV processing device  408  performs mobile communication function via the mobile communication unit  402 , then the function of the AV processing device  408  will be analogous to a mobile phone, and the notebook computer  406  will function like a handset. Under this condition, the user can use the default functions of the notebook computer  406  as well as make a phone call at the same time. Similarly, if the AV processing device  408  performs the wireless network connection function via the wireless network connection unit  404 , since the notebook computer  406  already makes wireless connection to the AV processing device  408 , the notebook computer  406  can access the wireless network via the AV processing device  408 . Under this condition, the user can use the default functions of the notebook computer  406 , as well as browse Internet or send/receive emails. 
         [0025]    Therefore, by way of the wireless communication system  40 , the notebook computer  406  and the AV processing device  408  can establish wireless connection via the bluetooth communication function, and the notebook computer  406  and the AV processing unit  408  can thus share the resource of the wireless communication device  400 . 
         [0026]    To make a summary, according to the present invention, the wireless communication device can connect to an electronic device by means of plug and play, such that the electronic device can perform the first wireless communication function of the wireless communication device, and the other electronic devices can connect to the electronic device via the second communication function, and then perform the first wireless communication function. By using the present invention, the system resource can be saved, and the users&#39; convenience can be improved. 
         [0027]    Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention.
