Switching apparatus for cellular phone using general telephone and method for switching the same}

The present invention relates to a mobile communication system, in particular, a mobile phone call apparatus and method using a general telephone, which is applied to various mobile phones, so that a telephone call can be performed using a general telephone without carrying a mobile phone in a home. The present invention relates to a mobile phone call apparatus and method using a general telephone.

In general, PSTN (Public Switched Telephone Network) is a public telephone switching network that connects users' telephones through an exchange to provide voice data exchange services. Basically, it supports voice information exchange service for general home telephone use, and various data communication services also use public telephone exchange network. PSTN has been continuously developed since the era of Alexander Graham Bell, who invented telephone. It is a collection of circuit-switched telephone networks. Today's PSTNs are technically almost completely digital, with the exception of the end link portion from the telephone company to the user.

1 is a diagram illustrating a wiring configuration of a telephone in a home connected to a conventional general telephone network (PSTN).

In a typical home, a line from the outside is pulled in and connected to the telephones in parallel through the home telephone line. As such, home telephones can only be connected to the PSTN network, and mobile phones can also perform their own unique functions.

On the other hand, in recent years, the concept of the telephone is changing from wired to wireless due to the proliferation of cellular mobile communication and personal mobile communication (PCS).

However, with the increase in the spread of mobile phones, the use of mobile phones is gradually increasing in the home or workplace where landline phones are installed. Mobile phones have the convenience of making calls anytime, anywhere, but have the disadvantage of significantly higher communication rates than wired lines. Although the communication rates of mobile phones are getting lower due to the increase in the number of subscribers, the decrease in the price of terminals and the development of wired / wireless communication technology, there are still significant differences compared to the wired communication costs. In particular, in Korea, cases in which the teenagers spend excessive communication costs due to indiscriminate use of mobile communication, and also in a region such as a commercial area, cell phone users are concentrated, which causes a deterioration of the wireless environment.

Therefore, in consideration of the communication cost and the wireless environment, it is preferable to use a wired telephone in an environment in which wired telephone lines are adjacent to each other.

However, the mobile phone in the conventional mobile communication system does not have a service function that allows the user to perform a telephone call through the adjacent wired telephone network when the user is in close contact with the wired telephone such as at home or work. Therefore, the user not only bears a relatively unnecessary mobile communication fee, but also has a problem that the wireless capacity shortage of the base station frequently occurs by deteriorating a wireless environment in a crowded area such as a commercial area.

In addition, when the exchange is inactivated by the switching network circuit switching unit 100 is configured to automatically connect the circuit network connection unit 110.

In addition, the charger box is not controlled by the central control unit 210 and performs charging independently.

With reference to the pro chart shown in Figs. 5 to 7 the mobile phone call device using the general telephone of the present invention configured as described above will be described the operation and effect.

First, FIG. 5 illustrates a flow of a call from a PSTN network. When a call comes from a PSTN network, a ring is first detected by the ring signal detecting unit 40 so that the central control processor 70 currently has a home telephone line network. The state monitoring control unit 90 detects whether or not the call is in progress and disconnects the line network connection unit B 30 if it is not in a call and sends the ring signal of the PSTN network to a general telephone in the home as it is (basically, to the PSTN network in the initial state). By connecting the receiver, the receiver makes a call when the receiver picks up the receiver and restores the connection of the circuit connection B 30 and operates the DTMF receiver 80 as a call forward preparation operation to monitor the call forwarding request for any situation. .

At this time, if there is a notification to the user on the call due to a call request from the mobile phone during a call to the PSTN network, that is, a specific alarm signal, the user can make a call by accessing the wireless network by pressing a specific selection key (# or *). If you hang up the handset after completing the call on the PSTN network without entering a specific selection key (# or *), the ringing ringing from the mobile phone will ring on the regular telephone.

In the call forwarding connection, when a specific selection key is input by the user, the DTMF receiver 80 in the switching box receives this signal and controls the call waiting controller 60 in the central control processor 70 to connect the line of the PSTN network. It keeps the state waiting for existing caller. Also, the PSTN network line switching unit 50 cuts off the PSTN network and the home telephone in the home, and the state monitoring control unit 90 of the switching box and the state monitoring controller 190 of the charger box block the PSTN network and the home line in the home. By sensing and connecting the switching network line switching unit 100 is made a call to the wireless network through a mobile phone.

On the other hand, the call forwarding connection to the PSTN network after the call of the mobile phone, when the user enters the selection key again, the DTMF receiver 200 detects the DTMF signal in the charger box and terminates the connection of the switching network line switching unit 100. The first and second state monitoring controllers 90 and 190 detect the same. Subsequently, the PSTN network switching unit 50 reconnects the PSTN network, and the call waiting control unit 60 and the circuit network connection unit 20 are blocked. The DTMF receiver 80 is activated again by the second circuit network connection unit 30 and waits for an input for the call forwarding request of the user. By repeating these steps, the call is transferred by the call forwarding to the PSTN network and the wireless network by the user's selection key input.

If a ring signal is detected in the PSTN network (40), when the home telephone is busy, that is, the wireless network, the central control unit 210 of the switching box notifies the caller that the call is received from the PSTN network. In order to determine whether the user will receive a call from the PSTN network or continue the call by giving a specific signal through the second network connection 30 in the home in the call. In order to transfer the call to the PSTN network, the user enters a selection key to connect to the PSTN network from the wireless network that was being used, which repeats the same operation as described above.

6 is a flowchart when a call is received by a mobile phone. First, when a call is received by the mobile phone, the charger box detects the incoming call by detecting a change in the magnitude of the RF signal and the charging current transmitted by the incoming signal detection unit 160 to access the base station, and the central control processor. 210 determines whether or not to talk to the PSTN network.

If it is not in a call, the charger box controls the circuit network connection unit 110 to inform the state monitoring controller 90 in the switching box that a call is made to the mobile phone. Subsequently, the switching box receiving the signal blocks 50 a home telephone line connected to the PSTN network.

Then, the state monitoring controller 90 detects this, and in the charger box, the switching network line switching unit 100 is connected, and the ring signal made by the central control unit 210 is amplified and supplied by the exchange control unit 120 to ring the signal to a general telephone. Will be sent.

At this time, when the user lifts the handset, the exchange control unit 120 detects the closed loop signal of the line to enable the call of the cellular phone. If there is no call request from the PSTN network, the exchange controller 120 initializes the call.

In addition, even in the case described above, when a call is received from the PSTN network during a call, the ring is detected by the ring signal detecting unit 40 of the charger box, and the line network connection unit 30 is connected to send an alarm signal. Press to cut off the switching network circuit switching unit 100, and transmits the melody indicating the waiting state of the call to the mobile phone, the call is made by the call transfer by activating the PSTN network in the switching box.

In addition, if a call is received by a mobile phone when a call is received through the PSTN network, and an incoming signal is detected (160), the central control processing unit 210 of the charger box receives a call to the mobile phone through the network connection unit 110 to the user in the call. Notify me of call waiting and call transfer by incoming call to mobile phone.

In addition, in order to make a call connection with a mobile phone, when a user inputs a selection key, the user waits and maintains a call with the PSTN network and makes a call to the mobile phone.

FIG. 7 is a flowchart showing a call attempt to a PSTN network and a call attempt to a mobile phone in a home, and when a user picks up the handset, a DTMF in the circuit network connection unit 30 is detected by detecting a hook-off signal by a state monitoring controller in a switching box. Connect the receiver 80 and wait for the user's response (wireless network call when the selection key is entered).

Since the switching box is basically connected to the PSTN network, when dialing, the call is made through the PSTN network. When the user wants to make a call over the wireless network, when the user presses the SELECT key, the switching box receives this signal to connect to the PSTN network. Block it. In this case, the call waiting controller of the PSTN network does not operate. Then, in the charger box, the exchange control unit 120 is activated, as described above with reference to FIGS. 5 and 6.

In this way, when the user wants to use the wireless network through the mobile phone, the user is connected to the exchange control unit 120 and dials it, which is stored in the central control processing unit 210 registry of the charger box and when the user presses a predetermined designated key. The cellular phone initiates communication by dialing into a wireless network and then the call and call forwarding to the wireless network and the PSTN network are controlled in the same manner as described above.

Although the flow of the call process to the PSTN network and the wireless network has been described above, the charging unit 170 charges the mobile phone mounted by an independent function without being controlled by the central control processing unit 210, respectively, and rapidly charges and fully charges the battery. Do this.

In the case of data communication through a mobile phone separately from the voice call, the data line connection unit 150 processes and modifies the data according to the interface of the other party to perform data communication according to the prow shown in FIG. 6.

Finally, the power supply units 10 and 180 respectively installed in the switching box and the charger box are designed to supply power for driving each circuit.

As described above in detail, according to the present invention, a mobile phone call device and method using a general telephone can be used for voice calls of a general telephone and a mobile phone in a home using a general telephone used in a home, and also a digital connection device to a charger box. There is an advantage that the data communication and the connection to the IP network to the wireless network can be made through.

In addition, the present invention has the advantage that can be used in conjunction with wireless data communication and mobile IP network by using the telephone line infrastructure installed in the existing home to replace the wired communication network that is introduced into the home.

In addition, the mobile phone call apparatus of the present invention is configured with a PSTN network as a basic connection, but the flow order or control order may be changed when connected to the center of the wireless network, and thus the technical spirit of the present invention is not limited thereto. It is apparent that various modifications and variations are possible in light of the present invention without departing from this scope.
