The cellular phone mounting base 10 fixed to the main body of the fixed- web phone 1 is used for the placement and retaining of a cellular phone 3. Inside the cellular phone mounting base 10 is disposed a cellular phone signal receiving terminal 101 which can be engaged with a socket 301 of a cellular phone 3 so that signals and power of the fixed-web phone 1 and the cellular phone can be exchanged.

The charger unit 13 is used to supply electrical power to a battery of the cellular phone 3.

The incoming call detecting unit 13 is used to detect if an incoming call is received and intercommunication of a cellular phone is carried out so as to control the operational connection position of the fixed-web phone/cellular phone switching unit 16.

The fixed-web phone/cellular phone switching unit 16 is responsible for switching connection between a fixed-web communication or cellular phone communication via fixed-web telephone 1 and is subject to the control of the incoming call detecting unit 12.

The fixed-web phone circuit 17 serves to connect a circuit of the fixed-web telephone to a fixed-web network system so as to meet operational specifications of a

fixed-web telephone.

The acoustic frequency signal amplifying unit 14 is used to properly amplify the output or input acoustic frequency signals of a cellular phone.

The phone picking up/hanging up device 15 is used to detect if a phone is picked up or hanged up for deciding a phone being in use or not.

The phone receiver 19 is a means used to provide users at both ends of a phone line to send out and receive sound signals.

Thereby when the cellular phone 3 is placed inside the cellular phone mounting base 10 with the cellular phone signal receiving terminal 101 engaged with the socket 301 of the cellular phone 3, the cellular phone 3 is then connected to a fixed-web telephone 1. In a standby state, the battery of the cellular phone 3 is charged by the charger unit 13. When an incoming call is being received by the cellular phone 3, the incoming call detecting unit 12 checks if it is a cellular phone call and it is connected or not so as to control the fixed-web phone switching unit 16 to put the switch at points of Al, A2. If it is a phone call in a fixed- web network system, the switch is put at points of B1, B2. At the same time, the output and input acoustic frequency signals of the cellular phone 3 are amplified by the acoustic frequency signal amplifying unit 14. Then the amplified signals are converted into acoustic frequency signals meeting specifications of a fixed-web

telephone by way of the fixed-web phone circuit 17 whereby a phone call of a cellular phone 3 can be received by a fixed-web telephone 1.

The phone picking up/hanging up device 15 can control the connection of the system according to the detection of if the phone receiver is picked up ( switched to Cl, Dl connection points) or hanged up.

Referring to Fig. 4, another embodiment of the present invention is illustrated wherein the fixed-web phone 2 of the present invention is comprised of cellular phone mounting base 20, an incoming call detecting unit 22, a charger unit 23 (not shown), an acoustic frequency signal amplifying unit 24, a fixed-web phone/cellular phone switching unit 26, a fixed-web phone circuit 27, a dialing unit 28, a phone receiver 29,a phone receiver/hand free device switching unit 25, a hand free device circuit 211. When the fixed-web telephone or cellular phone is in operation, a user can use the phone receiver/hand free device switching unit 25 to optionally select either the phone receiver 29( connecting to points el, e2) or the hand free device (connecting to points fl, f2) for carrying out a phone call operation. In case of the hand free device being used, the hand free device circuit 211 can supply a microphone MIC for voice input means and a speaker for voice output means.

Referring to Fig. 5, a third embodiment of the present invention is illustrated wherein the fixed-web telephone 4 of the present invention is comprised of

cellular phone mounting base 40, an incoming call detecting unit 42, a charger unit 43 (not shown), an acoustic frequency signal amplifying unit 44, a fixed-web phone/cellular phone switching unit 46, a fixed-web phone circuit 47, a dialing unit 48, a phone receiver 49,a phone receiver/hand free device switching unit 45, a hand free device circuit 411. It is identical to the second embodiment as shown in Fig. 4, and the only difference is that in Fig. 5, an additional cellular phone dialing and digital control code generating unit 412 is used. By switching the dialing operation of the dialing unit 48 to a cellular phone dialing operation, the cellular phone dialing and digital control code generating unit 412 will activate the cellular phone 3 to perform a dialing operation so that the dialing operation of a fixed-web telephone 4 can be converted to a dialing operation of the cellular phone 3.

A fourth embodiment of the present invention is illustrated in Figs. 2, 6, wherein the fixed-web phone 5 of the present invention has a cordless receiver 59 which is equipped with a RF receiving/transmitting circuit 591. the fixed-web telephone 5 is comprised of cellular phone mounting base 50, an incoming call detecting unit 52,a charger unit 53 (not shown), an acoustic frequency signal amplifying unit 54, a fixed-web phone/cellular phone switching unit 56, a fixed-web phone circuit 57, a phone receiver/hand free device switching unit 55, a hand free device circuit 511 and cellular phone dialing and digital control code generating unit

512. Those cited components work as those described in Fig. 5, the only difference is that an additional RF receiving/transmitting circuit 513 and an antenna 514 are adopted.

The feature of the fourth embodiment is that cordless receiver 59 can be used to receive a call transmitted to a cellular phone or can make a dial operation for a cellular phone. When a call to a cellular phone is being received and it is detected by the incoming call detecting unit 52, the fixed-web phone/cellular phone switching unit 56 is shifted to connect to points Al, A2. At the same time, the acoustic frequency signal amplifying unit 54 works to amplify the input and output acoustic frequency signals of the cellular phone 3, which are then selectively switched by the phone receiver/hand free device switching unit 55. In case of using the hand free device to receive a phone call, the hand free device circuit 511 will activate the microphone MIC, speaker SP to transmit acoustic input and output of a phone call. In case of using the cordless receiver 59 to receive a phone call, the RF receiving/transmitting circuit 513, antenna 514 can cooperate with the RF receiving/transmitting circuit 591 so as to enable a person to make a phone communication via the cordless receiver 59. Moreover, by way of dialing on a dialing unit 592 of the cordless receiver 59, the cellular phone 3 can be accordingly dialed simultaneously. This is done as a result of using the RF receiving/transmitting circuit 591 to issue dialing operation signal codes

which are received by the antenna 514 and the RF receiving/transmitting 513, then the cellular phone dialing and digital control code generating unit 512 will activate the cellular phone 3 to perform a dialing operation.

In summary, the present invention enables users of cellular phones to make phone calls in offices or in houses via fixed-web telephones (i.e. cable telephones) so that people can be better protected from bad influence of microwave produced in using cellular phones in one aspect and can make a standby cellular phone constantly charged in another aspect.
