The operation of the portable device according to the present invention is divided into two operations. The first is when the portable device 200 is connected to the cradle 152, and the second is when it is separated from the cradle 152.

First, the first operation will be described through a reception process. At this time, the second switch unit 218 is switched to the external antenna 150 under the control of the second controller 210. Accordingly, the portable device 200 receives a radio frequency (RF) through an external antenna terminal of the external antenna 150 and the fourth connector 154. This is to overcome this by using an external antenna 150 because indoors may have inferior reception sensitivity. The received radio frequency is input to the RF unit 214, and is converted into a signal of an intermediate frequency (IF) by the RF unit 214 and output. The intermediate frequency is input to the IF unit 215. The IF unit 215 separates the in-phase and quadrature signals through quadrature demodulation and the like, and inputs the necessary analog baseband signal to the baseband unit 216 through appropriate filtering. The baseband unit 216 receives the analog baseband signal and converts it into a digital signal in an internal analog / digital converter (not shown), which is again subjected to demodulation and decoding based on an air interface standard of each system. After converting into a Pulse Code Modulation (PCM) signal and performing an appropriate PCM decoding process, the audio unit 217 is converted into an analog signal and output. When the portable device 200 is connected to the holder 152, the analog signal is inputted to the controller 101 of the main body 100 through the fourth connector 154 and the second connector 131 of the holder 152 through the external interface 211. In this case, the user hears the voice through the handset 130 through the first connector 132 if the mode of the main body 100 is the normal mode, and hears the voice through the speaker 113 in the speakerphone mode.

The operation according to the reception process has been described. Hereinafter, a description will be given of the transmission process, and the main body 100 performs dialing and a plurality of function controls, and transmits a voice signal input from the handset 130 or the microphone 115 through the control unit 101, the second connector 131, and the fourth connector 154. Send to 200. The portable device 200 receives the voice signal output from the main body 100 through an external interface 211 and converts the voice signal into a wireless signal through the audio unit 217, the baseband unit 216, the IF unit 215, and the RF unit 214, and then outputs the audio signal to the second switch unit 218. do. At this time, the second switch unit 218 is switched to the external interface 211 under the control of the second control unit 210. Accordingly, the radio signal is input to the external interface unit 211, and is input to the fourth connector 211 through the antenna terminal of the external interface unit 211 and transmitted to the repeater through the external antenna 150.

At this time, the second switch unit 218 is switched to the antenna ANT 201 under the control of the second control unit 210. The radio signal received through the antenna 201 is input to the audio unit 217 through the RF unit 214, the IF unit 215, and the baseband unit 216. At this time, the audio path of the audio unit 217 is not switched to the external interface unit 211 under the control of the second control unit 210, and is connected to the speaker SP 219 and the microphone 220. Accordingly, the voice signal is output as voice through the speaker SP 219.

The transmission process according to the second operation will be described.

First, when dialed through the second key input unit 213 and the second display unit 212, the second control unit 210 forms a wireless link with the repeater through the baseband unit 216, the IF unit 215, the RF unit 214, and the antenna 201. When the wireless link is formed, the second controller 210 converts the voice signal input through the microphone 220 into a wireless signal through the audio unit 217, the baseband unit 216, the IF unit 215, and the RF unit 214, and then transmits the signal through the antenna 201. .

If the second controller 210 detects the connection with the fourth connector 154, the controller 154 executes the combined mode operation processing routine. If not, the second controller 210 proceeds to the operation 405 and executes the independent mode operation processing routine.

It is a flow chart.

First, referring to FIG. 5, in operation 501, the second controller 210 of the portable apparatus 200 controls the audio unit 217 to switch the voice path to the external interface unit 211. Then, the second controller 210 controls the second switch 218 to switch to the external interface 211 to connect the external antenna 150. After switching the voice path to the external interface unit 211 and the wireless signal receiving path to the external antenna 150, the second controller 210 determines whether a call is received by the RF unit 214 through the external antenna 150 and the external interface unit 211 in step 505. The control unit 101 checks whether transmission is attempted from the control unit 101 of the main body 100 through the second connector 131, the fourth connector 154, and the external interface unit 211. When the incoming and outgoing call is attempted, the second controller 210 forms a wireless link through the relay station in step 507 to form a communication path, and transmits the wireless signal received through the wireless link to the external antenna 150, the fourth connector 154, and the external interface. The signal is received through the unit 211 and transmitted to the main body 100 through the RF unit 214, the IF unit 215, the baseband unit 216, the audio unit 217, and the external interface unit 211. In addition, the voice signal input from the main body 100 through the external interface unit 211 is transmitted through the audio unit 217, the baseband unit 216, the IF unit 215, the RF unit 214, the external interface unit 211, the fourth connector 154, and the external antenna 150. During the call, the second controller 210 determines whether the call ends by checking whether call termination data is input from the main body 100 in step 509. At this time, when call termination data is input, the radio link is released and the call is terminated.

In step 601 of FIG. 6, the controller 101 of the main body 100 checks whether a call is received through the portable device 200 or a call is attempted through the key input unit 103. When a call is received or an attempt is made, the controller 101 checks whether the current mode is the speakerphone mode in step 603. As a result of the test, in the speakerphone mode, the controller 101 proceeds to step 605 to switch the call path to the speaker 113 and the microphone 115 and proceeds to step 609 to initiate a call. However, if it is not the speakerphone mode, the controller 101 proceeds to step 607 to switch the call path to the handset 130, and then proceeds to step 609 to initiate a call. During the call, the controller 101 determines whether a call termination key is input from the key input unit 103 in step 611. If the call termination key is input from the key input unit 103, the controller 101 proceeds to step 613 to transmit the call end data to the mobile device 200 and then terminates the call. do.

7 is a flowchart illustrating a method of operating a portable device in an independent mode in which the portable device of FIG. 4 operates independently.

If the portable device 200 is not connected to the main body 100 in step 401 of FIG. 4, the second controller 210 controls the second switch unit 218 in step 701 to switch the radio signal transmission / reception path to the internal antenna 201. In operation 703, the audio unit 217 is controlled to switch the voice path to the internal speaker 219 and the microphone 220 of the mobile device 200. After the voice path and the radio signal transmission / reception path are switched, the second controller 210 checks whether the call is received through the antenna 201 or the call is attempted through the second key input unit 213 in step 705. When the incoming and outgoing call is attempted in step 705, the second controller 210 establishes a wireless link with the repeater and starts a call in step 707. When the call starts, the second controller 210 checks whether the call end key is input in step 709 in step 709, and terminates the call when the call end key is input.

As described above, the present invention has an advantage of improving mobility of the wireless subscriber device by having a mobile portable device capable of forming a wireless link independently of the repeater.
