Abstract

The present invention provides a telecommunication system, a mobile phone and a calling method adapted for the telecommunication system. The telecommunication system includes a mobile phone connected to a wireless network and a wired phone connected to a wired network. The mobile phone and the wired phone communicate each other within a predetermined coverage area. When there is not a wired phone within the predetermined coverage area or there is a wired phone within the predetermined coverage area and the current state of the wired phone is busy, the mobile phone makes a call via the wireless network. If there is a wired phone within the predetermined coverage area and the current state of the wired phone is idle, the mobile phone sends a phone number to the wired phone, and the wired phone makes the call via the wired network.

Claims

1. A telecommunication system comprising:

a mobile phone, connected to a wireless network; and

a wired phone, connected to a wired network;

wherein the mobile phone comprises;

a receiver, for receiving voice signals of a called party, wherein the voice signals are from the wireless network or transmitted by the wired phone from the wired network;

a first communicating unit configured for communicating with the wired phone within a predetermined coverage area, receiving the voice signals from the called party of the wired network via the wired phone at real time, and sending voice signals from a user of the mobile phone to the called party of the wired network via the wired phone at real time; and

a central processing unit (CPU), for controlling the first communicating unit to send a search signal in response to a phone number input operation, judging whether the first communicating unit receives a response signal from the wired phone within a predetermined time period, making a call via the wireless network if the first communicating unit doesn'"'"'t receive the response signal or the first communicating unit receives the response signal and a value of the response signal is a first value, controlling the first communicating unit to send the phone number signal to the wired phone, if the first communicating unit receives the response signal and the value of the response signal is a second value, processing the voice signals from the called party of the wired network via the wired phone to the receiver, and processing the voice signals from the user to the called party of the wired network via the wired phone; and

the wired phone comprises;

a second communicating unit configured for communicating with the first communicating unit within the predetermined coverage area, sending the voice signals from the called party of the wired network to the first communicating unit at real time, and receiving the voice signals from the user of the mobile phone via the first communicating unit to the wired network at real time; and

a processing unit, for acquiring the current state of the wired phone and controlling the second communicating unit to send the response signal to the mobile phone in response to the search signal from the mobile phone, and outgoing the call via the wired network if the current state of the wired phone is idle.

2. The telephone system as recited in claim 1, wherein the wired phone further comprises a storage unit for storing a phone number.

3. The telephone system as recited in claim 1, wherein if the current state of the wired phone is busy, the processing unit generates the response signal with the first value to the second communicating unit;

if the current state of the wired phone is idle, the processing unit generates the response signal with the second value to the second communicating unit.

4. The telephone system as recited in claim 1, wherein the first communicating unit and the second communicating unit are BLUETOOTH modules.

5. The telephone system as recited in claim 1, wherein the first communicating unit and the second communicating unit are radio frequency identification (RFID) modules.

6. A mobile phone, connected to a wireless network, for communicating with a wired phone connected to a wired network within a predetermined coverage area, comprising:

a receiver, for receiving voice signals of a called party, wherein the voice signals are from the wireless network or transmitted by the wired phone from the wired network;

a communicating unit, for communicating with the wired phone within a predetermined coverage area, receiving the voice signals from the called party of the wired network via the wired phone at real time, and sending voice signals from a user of the mobile phone to the called party of the wired network via the wired phone at real time; and

a central processing unit (CPU), for controlling the communicating unit to send a search signal in response to a phone number input operation, judging whether the communicating unit receives a response signal from the wired phone within a predetermined time period, outgoing a call via the wireless network if the communicating unit doesn'"'"'t receive the response signal or the communicating unit receives the response signal and a value of the response signal is a first value, controlling the communicating unit to send the phone number signal to the wired phone, if the communicating unit receives the response signal and the value of the response signal is a second value, processing the voice signals from the called party of the wired network via the wired phone to the receiver, and processing the voice signals from the user to the called party of the wired network via the wired phone.

7. A calling method for a telecommunication system, wherein the telecommunication system comprises a mobile phone connected to a wireless network and a wired phone connected to a wired network, the mobile phone comprises a first communicating unit, the wired phone comprises a second communicating unit, and the first communicating unit and the second communicating unit communicate each other within a predetermined coverage area, the method comprising:

generating a search signal in response to a phone number input operation on the mobile phone;

searching for the wired phone;

judging whether a response signal is received from the wired phone within a predetermined time period;

making a call via the wireless network if the first communicating unit does not receive the response signal; and

making a call via the wireless network if the first communicating unit receives the response signal and a value of the response signal is a first value;

or

making the call via the wired phone if the first communicating unit receives the response signal and the value of the response signal is a second value.

8. The calling method as recited in claim 7, further comprising:

storing the phone number in the wired phone after making the call via the wired phone.

9. The calling method as recited in claim 7, wherein the first communicating unit and the second communicating unit are BLUETOOTH modules.

10. The calling method as recited in claim 7, wherein the first communicating unit and the second communicating unit are radio frequency identification (RFID) modules.
