First, when a ring signal is input to the telephone network connection unit 60 of the fixed terminal FT through the PSTN, the ring signal is detected by the ring generating unit 54 and the DAA 56 (step S51). The ring generator 54 drives the ring speaker 52 to output the bell signal, and the DAA 56 notifies the central processing unit 10 that the ring signal has been received from the PSTN via a signal line (not shown) ( Step S52).

Next, the central processing unit 10 transmits the call request signal to the RF transmit / receive module 110 of the mobile terminal MT1 through the data communication channel of the RF transmit / receive module 12, whereby the call request signal transmits and receives RF. It is input to the central processing unit 100 via the data communication channel of the module 110. Accordingly, the central processing unit 100 controls the ring tone to be output through the ring speaker 240 (step S53).

Subsequently, the central processing unit 10 of the fixed terminal FT determines whether the handset 40 is lifted by the user (i.e., it is determined whether a hook-off signal is input from the call intention detecting unit 14). Step S54).

If it is determined in step S54 that the handset 40 is lifted, the central processing unit 10 controls the switch 38 to the on state, and at the same time, the common terminal c1 is connected to the switch 34 at the contact point b1. Control to be connected to the control panel (step S55). Accordingly, the other party's general telephone (NP1) via the handset 40, the speech network circuit section 28, the hook switch 36, the switch 38, the electromagnetic wave / surge prevention circuit section 58, the telephone network connection section 60, and the PSTN. A call path leading to) is formed (step S56).

As described above, when the user of the fixed terminal FT puts down the handset 40 after making a call by forming a call with the general telephone of the other party, the state (that is, the hook-on state) is the call intention detecting unit. It is detected by 14 and input to the central processing unit 10. Therefore, the central processing unit 10 recognizes the end of the call, controls the switch 38 to the off state, and simultaneously controls the common terminal c1 of the switch 34 to the neutral state (steps S57 to S58). After that, the normal telephone mode is terminated.

On the other hand, when the user receives a call through the mobile terminal MT1 in a state where the handset 40 of the fixed terminal FT is not lifted in step S54, the hook is received from the central processing unit 100 of the mobile terminal MT1. The off signal is transmitted to the fixed terminal (FT) through the data communication channel of the RF transmission / reception module 110. Accordingly, when the central processing unit 10 of the fixed terminal FT receives the hook-off signal through the RF transmission / reception module 12 (step S59), the central processing unit 10 makes a call from the mobile terminal MT1. Recognizing that the received signal is received, the common terminal c2 of the switch 42 is controlled to be connected to the contact point d2, and the common terminal c3 of the switch 50 is controlled to be connected to the contact point a3 (step S60). ). Thereby, the mobile terminal MT1 and the general telephone apparatus NP1 are made to communicate via the fixed terminal FT in the manner described in step S44 of FIG. 7 (step S61).

After the call is made in this way, when the user of the mobile terminal MT1 terminates the call, this state is detected by the central processing unit 100 of the mobile terminal MT1, and the call termination signal is received by the RF transmission / reception module 110. The call termination signal is inputted to the central processing unit 10 through the RF transmission / reception module 12 of the fixed terminal (FT). At this time, the central processing unit 10 recognizes that the call is terminated from the mobile terminal MT1 and controls the common terminal c2 of the switch 42 and the common terminal c3 of the switch 50 to be in a neutral state, respectively. (Steps S62 to S63). As a result, the call path between the mobile terminal MT1 and the general telephone NP1 is disconnected, and the general telephone call mode is terminated.

Next, with reference to Fig. 9, the Internet phone mode in the case of making an Internet phone via a LAN in a fixed terminal of a wired / wireless communication terminal according to the present invention will be described. Here, it is assumed that the fixed terminal FT is not provided with a modem 48, and the Ethernet controller 18 and the digital communication connection unit 20 are connected to the LAN.

In FIG. 1, when a user wants to talk to a desired Internet phone IP using a fixed terminal FT, the Internet phone mode is set by the user's operation. At this time, when the call intention detecting unit 14 detects the hook-off state of the handset 40 and inputs it to the central processing unit 10, the central processing unit 10 contacts the common terminal c1 of the switch 34. It controls so that it may be connected to a1), and it controls so that the common terminal c2 of the switch 42 may be connected to the contact a2 (step S71-S73). Accordingly, signal paths of the handset 40, the switch 34, the handset amplifier 32, the switch 42, the signal converter 44, the DSP 46, and the central processing unit 10 are formed. .

In addition, when a user inputs a telephone number for the other party's Internet telephone (IP) by using a numeric key or the like of the key matrix 24, the input is detected by the key matrix control circuit unit 22 and the central processing unit 10 Is delivered).

Thereafter, the central processing unit 10 generates a call request signal including the inputted party's telephone number and outputs it to the Internet through the Ethernet controller 18 and the digital communication connection unit 20 using UDP (User Datagram Protocol). do. When the call server CS receives the call request signal, the call server CS searches the database for the IP address of the counterpart corresponding to the counterpart phone number, and then sends a call request confirmation signal including the IP address of the counterpart to the corresponding fixed terminal (FT). Return to

Thus, the user's voice input through the handset 40 of the fixed terminal is amplified by the handset amplifier 32 and then converted into a digital signal by the signal converter 44 and compressed by the DSP 46. The compressed coded voice signal is then packetized in a Real-time Transport Protocol (RTP) format in the central processing unit, and then the packet data is packetized again in UDP format, followed by the Ethernet controller 18 and the digital communication connection. Through the Internet 20 is transmitted to the other party's Internet phone (IP).

On the other hand, the voice data packet of the other party in UDP format inputted from the other party's Internet telephone (IP) through the digital communication connection unit 20 and the Ethernet controller 18 is inversely reversed from the transmission process described above in the central processing unit. Only digital compressed voice data is output to the DSP 46 through this. The digital compressed voice data is decoded and decoded by the DSP 46, converted into an analog signal by the signal converter 44, and then output to the handset 40 in an amplified state by the handset amplifier 32.

In this way, a communication path between the fixed terminal FT and the other party's Internet telephone IP is formed (step S75).

In this way, when the user of the fixed terminal FT puts down the handset 40 after making a call by forming a call with the internet telephone of the other party, this state (that is, the hook-on state) is the call intention detecting unit. It is detected by 14 and input to the central processing unit 10. Therefore, the central processing unit 10 recognizes the end of the call, controls the common terminal c1 of the switch 34 to be in a neutral state, and simultaneously controls the common terminal c1 of the switch 42 to a neutral state. Further, the central processing unit 10 notifies that the call connection is released to the other party's Internet telephone IP, and also notifies the call server CS of the end of the call (step S79). Thereafter, the central processing unit 10 ends the Internet phone mode.

This compressed coded voice signal is then packetized in a Real-time Transport Protocol (RTP) format in the central processing unit, and then the packet data is packetized again in UDP format and then modulated in PPP format by the modem 48. Then, it is transmitted to the Internet telephone (IP) via the switch 50, the DAA 56, the electromagnetic wave / surge prevention circuit section 58, the telephone network connection section 60, the PSTN, the ISP, and the Internet.

On the other hand, the PPP format voice data packet received from the other party's Internet telephone (IP) via the ISP and PSTN is demodulated by the modem and decomposed into a UDP format packet, and then the central processing unit is different from the above transmission process. Only the digital compressed voice data is output to the DSP 46 through the inverse decomposition process. The digital compressed voice data is decoded and decoded by the DSP 46, converted into an analog signal by the signal converter 44, and then output to the handset 40 in an amplified state by the handset amplifier 32.

In this way, a communication path between the fixed terminal FT and the other party's Internet telephone IP is formed using the modem 48 (step S87).
