Next, the operation of this embodiment will be described with reference to the flowcharts of FIGS. 1. Description of operation upon receipt of an incoming call : First, the operation upon receipt of an incoming call will be described with reference to FIG. First, it is determined whether or not the plug 11a is connected (step S1). At this time, the plug 11b
When the plug 11a is not connected to, it is determined whether or not there is a wireless incoming call (step S2). This determination is made by the telephone control unit 3 when the wireless unit 6 receives the incoming call signal.

When an incoming call is received by radio, radio line reception processing is performed (step S3). The wireless line reception processing will be described. When the reception is performed as an ordinary mobile phone, the radio wave from the base station is received by the antenna 7 and the signal demodulated by the wireless unit 6 is the calling telephone number of the own station. , Is a series of processes in which a ringing tone is generated using the speaker unit 1 and a user operates a hook switch of a mobile phone (not shown) to make a call possible and to make a call. When the wireless reception process is completed or there is no wireless incoming call in step 2, the process returns.

On the other hand, when the plug 11b is connected to the plug 11a in step 1, the selection button 4 is continuously pressed.
ON / OFF is determined (step S4).

If the selection button is not selected, that is, it is not turned on, it is judged whether or not there is an incoming call by wire (step S5). This determination is made when the line control unit 8 detects an incoming signal and the telephone control unit 3 receives an incoming call by wire.

When there is an incoming call by wire, a wired line reception process is performed (step S6). Explaining the wired line reception process, by receiving as a wired telephone,
The circuit control unit 8 detects an incoming signal sent through the line, and when it detects it, informs the telephone control unit 3 of this. The telephone control unit 3 uses the speaker unit 1 to generate a ringing tone. Then, the user operates a hook switch (not shown) to make the call possible, and a series of processing is performed. When the wired reception process is completed, the process returns.

On the other hand, if there is no incoming call by wire in step S5, the process proceeds to step S2 to judge whether there is an incoming call by radio, and then the above-mentioned step S3 or return processing is performed.

In addition, one of the judgments in step 4,
When the selection button is turned on, simultaneous processing of both wired and wireless lines starts (step S7 and subsequent steps). This process uses the vacant line when receiving an incoming call, for example, the wireless telephone line when receiving an incoming call through a wired telephone line, and uses the preset telephone number of the designated destination. This is a process of making a call to the terminal having the same, establishing a call, and then connecting the incoming call via a wire to the terminal having the designated destination telephone number.

One specific example of the above processing function is as follows. It is assumed that a user who owns a mobile phone makes a wired call to a user's home from a person who does not know the phone number of the mobile phone while traveling to another office where the wired phone is installed. At this time, of course, the user cannot answer the wired telephone. However, if the home telephone is the mobile telephone with the wired connection function of the present invention and the telephone has the above-mentioned predetermined settings, the office where the user is through the wireless telephone line of the telephone. You can connect the wired telephone at home to the wired telephone of.

This will be explained according to the processing steps.
It is checked whether or not the designated telephone number is registered (step S7), and if it is not registered or changed, registration work is performed (step S8). At this time, if there is an incoming call by wire, the call is made using a wireless telephone line (step S10). If there is an incoming call by wireless, the call is made using a wired line (step S12). Also,
At this time, if there is no incoming call on any of the lines, the process returns, and unless the state of the plug connection or the state of the selection button is changed, the standby in the simultaneous processing is continued. A call is established by the call originating in step S10 or step S12 (step S13), and the incoming call is connected to the terminal having the designated destination telephone number (step S14). After that, when an end signal is output from the terminal that gives an incoming call to the mobile phone with the wired connection function or the terminal having the telephone number of the designated destination, the process is terminated and the process returns.

Here, how to connect to the other line when there is an incoming call through either the wired or wireless line will be described below. However, the mobile phone in the stand-by state is in a state in which the position registration has been completed for the wireless base station, and on the other hand, it is also in the call signal monitoring state for the wired line.

(1) Operation when an incoming call is received via a wired line: When an incoming call is received via a wired line during standby while the selection button 4 is turned on, the mobile phone is preset. Make a call to a telephone number using a wireless line.
After that, for example, until there is a response signal indicating that the other party has come out through the exchange (radio base station) on the radio side, it is assumed that the ringing tone is returned to the person who is making the wired telephone call. Then, when there is a response on the wireless side, the mobile phone responds to the wired line side in response. As described above, only when the selection button 4 is turned on, after the line on the wireless side is established, a response signal is automatically sent from the selection signal sending circuit to the calling signal from the wired line, and the exchange on the wired side and the mobile phone are connected. Establish a line between Conversely, select button 4
When is not turned on, a ringing tone is output to notify the call without automatically answering. In this way, both wired and wireless lines are established.

(2) Operation when an incoming call is received via a wireless line: In this case also, the operation is basically the same as in the case of (1) above. That is, if there is an incoming call through the wireless line while waiting for the selection button 4 being turned on, the mobile phone calls the preset telephone number using the wired line. . After that, for example, until there is a response signal indicating that the other party has come out through the wired exchange, it is assumed that the ringing tone is returned to the person making the wireless telephone call. Then, when there is a response on the wired side, the mobile phone responds to the wireless line side in response. In this way,
Both wireless and wired lines will be established.

(3) Operation during a call after establishment of a common line for both wired and wireless: After a common line is established, if there is some inquiry from the wireless side (some voice data comes in), this is demodulated. Then, it is converted into a voice signal through a data decoding process and is connected to a modulation unit 18 for a wired line by switching the wired / wireless selection unit 13, where it is generated as wired transmission data and an appropriate line control signal is generated. A call is realized by sending it out to a wired line together with.

On the other hand, regarding the inquiry from the wired side,
The flow is the reverse of the above. That is, the data received through the wired line is demodulated by the wired demodulation unit 18, and an audio signal is extracted from the data on the wired line. This is wired /
It is selected by the wireless selection unit 13 and is connected to the voice encoding unit 16 by switching. The operation thereafter is the same as the operation of a general mobile phone. The encoded signal is modulated as transmission data by the transmission data generation unit 17. The output from here is sent to the wireless unit 6. The output from the wireless unit 6 is modulated and amplified by a wireless transmission unit (not shown), and then sent to the wireless base station. This realizes the call. 2. Description of operation at the time of transmission : Next , the operation at the time of transmission will be described with reference to FIG. When it is not off-hook (when the hook switch (not shown) is not operated), the telephone transmission process (calling operation) is not performed. on the other hand,
When the hook switch (not shown) is operated to be in the off-hook state, it is determined whether or not the plug 11a is connected to the plug 11b (step S22).

If the plug 11a is not connected, wireless line transmission processing is performed. That is, a call is made and a call is made using a wireless telephone line. The wireless line transmission process will be described. When the ten-key pad on the operation unit 5 is operated to input the telephone number of the other party, the telephone control unit 3 which receives the dialed number makes a dial transmission, and the transmission signal is transmitted to the wireless unit 6. It is transmitted to the radio base station via the antenna 7. As a result, the other party is called and a call is established (step S23). When this process ends, the process returns.

On the other hand, when the plug 11a is connected to the plug 11b in step 22, the ON / OFF of the selection button 4 is subsequently determined (step S24).

When the selection button is not turned on, a wired line transmission process is performed. In other words, it is to make a call using a wired telephone line. This wired line transmission processing will be described. When the numeric keypad on the operation unit 5 is operated to input the telephone number of the other party, the telephone control unit 3 which receives the telephone number drives the line control unit 8 and the line control unit 8 causes the line to be connected. This is a series of processing of dialing through and calling after the other party responds to the call (step S25). When this process ends, the process returns.

On the other hand, when the selection button is turned on in step 24 and turned on, the simultaneous wired / wireless transmission process is started (step S26 and thereafter).

First, the telephone number of a terminal to make a call using a wired telephone line and the telephone number of a terminal to make a call using a wireless telephone line are input by the ten keys of the operation unit 5 (step S26). Then, the call is made with each telephone number to call the other party. After each of the other parties responds to the call, two calls are simultaneously established with the mobile phone with the wired connection function as a core (step S27). The control in step S27 ends and the process returns after the other party or the mobile phone with the wired connection function ends the call.
