FIG. 3 is a diagram showing the configuration of a wireless communication system having a plurality of wireless portable devices, in which a configuration of a wireless facsimile system is shown. The wireless facsimile system consists of a fixed device wireless unit 100 and a fixed device facsimile unit 200.

The fixture controller 32 controls the overall operation of the fixture. The fixed device controller 32 is a one-chip microprocessor, and includes a ROM for storing a program and a RAM for temporarily storing data generated while the program is being executed. The memory 33 includes an ID table for storing ID numbers of portable devices for identifying portable devices and a ring data table for each portable device for distinguishing a call request of each portable device according to an embodiment of the present invention.

4 is a flowchart illustrating a call service process according to an embodiment of the present invention for portable devices having the configuration as shown in FIG.

5 is a flowchart illustrating a call service process according to an embodiment of the present invention in a wireless communication system having the configuration as shown in FIG.

The call service performed in FIGS. 4 and 5 will be described based on a process in which the mobile device performs an extension call function with another mobile device through the main body or the portable device performs an extension call function with the main body.

An embodiment of the present invention will be described in detail based on the above-described configuration.

First, referring to an outgoing call service operation of a portable device, when a call key is generated in the keypad 10, the portable device controller 12 detects it in step 411 and controls the RF transmitter 16 and the RF receiver 18 to fix the RF link with the fixed device. To form. In this case, the fixing device control unit 32 detects this in step 511 and forms an RF link with the portable device. Thereafter, the portable device controller 12 accesses and outputs the ID number of the corresponding portable device from the ID table of the memory 14, and outputs dial information of the extension or the main body to be called in step 415.

Then, the fixed device controller 32 performs steps 513 to 517 to receive the unique ID number and dial information of the portable device output from the portable device, and then displays the unique ID number of the corresponding portable device. At this time, the method of displaying the ID number is displayed on the LCD of the OPE52 the ID of the portable device registered in the ID table of the memory 33, and also the unique ring data of the portable device registered in the ring data table of the memory 33 Is accessed and output on the voice processing section 62. Accordingly, when the mobile watch requests an outgoing call, the ID of the mobile device is displayed on the OPE52 and a unique ring signal of the mobile device is generated.

As described above, the fixed device controller 32 analyzes the dialing information received while displaying the ID of the mobile device requesting the outgoing call and analyzes whether the call service is possible. At this time, the call service may be an outgoing call or a trunk line call. In this case, when the mobile device requests an extension call with the fixed device, the fixed device control unit 32 analyzes the dialing data received and detects that the user has requested a call with the mobile device. Performs call service function with. Then, the portable device controller 12 recognizes that the call is available in step 519 and performs a call service function through the fixed device in step 521. When the calling mobile device or the called party terminates the call in the call service state as described above, the fixed device and the portable device notify the other party and terminate the call service.

When the portable device requests an outgoing call as described above, the portable device sends its own unique ID to the main body, and the main body receives a ring signal for recognizing the portable device of the outgoing request based on the ID number of the received mobile device. At the same time, the ID of the mobile device is displayed.

Second, referring to the incoming call service process of the portable device, when the incoming call occurs, the fixed device controller 32 detects it in step 531 and performs steps 533 to 537 to transmit the ID of the incoming mobile device. In this case, when the main body requests a call with a specific portable device, the fixed device controller 32 accesses and outputs the unique ID number of the corresponding portable device from the ID table of the memory 33 when requesting a call from the specific portable device. If there is no request from the device, after accessing and outputting the common ID number from the ID table, the mobile device waits for a response from the mobile device in step 539.

Then, when receiving, the portable device controller 12 receives the portable device ID number in step 433 and then performs steps 435-441 to generate an incoming ring signal. At this time, the portable device controller 12 accesses its own ID from the ID table of the memory 14 and compares it with the received ID. When the two IDs match, the portable device controller 12 stores the unique ring data of the portable device stored in the ring data table of the memory 14. Is accessed and output to the voice processing section 24. Then, the user listens to the unique ringing signal set in the portable device. If the received ID is not a unique ID of the corresponding portable device, the common ID is accessed from the ID table and compared with the received ID. When the two IDs match, the common ring data of the portable devices stored in the ring data table of the memory 14 is matched. Is accessed and output to the voice processing section 24. The user then listens to the common incoming ring signal. In this case, all portable devices generate an incoming ring signal. However, if the received ID is not the unique ID and the common ID of the corresponding portable device, the unique ID of the other portable device is received, so that the portable device transitions back to the standby state.

If the incoming ring signal is hooked off, the portable device controller 12 detects this in step 443, notifies that the fixed device is answered in step 445, and performs the incoming call service. Then, the fixed device controller 32 detects a response in step 539, outputs ACK data for the response in step 541, and performs a call service function with the responding portable device. In this case, when a plurality of mobile devices generate an incoming ring signal according to the common ID, the mobile device that responds performs the call service function in step 445, and the remaining mobile devices that do not respond generate the incoming ring signal by the response ACK data. Stop and transition to standby. When the called mobile device or the calling party terminates the call in the call service state as described above, the fixed device and the portable device notify the other party and terminate the call service.

As described above, in a wireless communication system in which a plurality of mobile devices make a call service through a main body, when an incoming call service of a mobile device is requested, a call service of a specific mobile device is output by outputting a unique ID of the mobile device when a call is requested. If there is no incoming request of a specific portable device, all the portable devices are notified of the incoming call, and the incoming mobile device performs an incoming call function.

As described above, when the portable device requests an outgoing call to the fixed device in the wireless communication system, the ID stored in each mobile device is sent together, and the main body recognizes the ID and displays the ID of the mobile device on the display unit. Here, the ID may be an extension number and name of the corresponding portable device. In addition, according to the order in which the portable device is registered in the main body, the sound which the main body informs when the main body is called is also configured differently so that the portable apparatus can be distinguished by the source without looking at the LCD screen of the main body.

In the wireless communication system including the main body and a plurality of portable devices as described above, when the portable device attempts to make an extension call with other portable devices through the main body and the main body, the main body can recognize the ID of the calling portable device, and also the main body. In addition to displaying the ID of the mobile device called in, there is an advantage that can generate a unique ring signal to identify the calling mobile device.
