The DTMF generating unit 112 generates a DTMF signal corresponding to the called party's telephone number, the intelligent network service access number, etc. under the control of the control unit 110 and provides the DTMF signal to the transmitting and receiving unit 114. Here, DTMF is a standard signal sent to the exchange when a button is pressed on the keypad of the telephone.

The transceiver 114 forms a LOOP with the originating base station 202 through the mobile communication module 118 in response to the control signal of the controller 110 to transmit a DTMF signal to the network side or is input through the handset 120. The voice signal of the user is transmitted to the mobile communication module 118 and the voice signal received from the mobile communication module 118 is transmitted to the handset 120. The hook switch detecting unit 116 monitors the state of the hook switch HS by the handset 120 and generates a "hook off" signal when the user lifts the handset 120 to provide it to the controller 110. .

The mobile communication module 118 is a wireless communication module for coupling the multifunction wireless telephone 100 according to the present invention to the mobile communication network 204 side, and communicates with the calling base station 202 in accordance with a general mobile communication standard.

The controller 110 is implemented by a microprocessor or the like and controls each of the building blocks according to a predetermined procedure as shown in FIGS. 5A to 5C to provide intelligent network telephone services (eg, prepaid card, postpaid card, credit card, etc.). It handles all operations that automatically dial a series of access numbers required for service and collect calls.

5A and 5B are flowcharts illustrating a setting mode operation of a multifunction wireless telephone according to the present invention. FIG. 5A is a procedure for setting or changing a password, and FIG. 5B is for changing an operation type or setting or changing an access number. Procedure.

Multifunction cordless telephone 100 according to the present invention has a function of automatically dialing the access number of a corresponding service when a specific service access button is pressed, a function of automatically dialing the access number previously entered, the card reader unit of the card reader unit. When the card is read through, it automatically determines the type of the card and has the function of automatically transmitting the access number of the intelligent network service.

In the embodiment of the present invention, when the handset is lifted, the direct dialing type (TYPE) of the direct type is directly connected only to a specific intelligent network service product, and when the user presses a service access button or reads a card such as a prepaid card, a postpaid card or a credit card. It operates by dividing into a multi-function type automatic dialing method (TYPE) that automatically recognizes the service type and automatically dials the corresponding access number. And the operation type (TYPE) of each of the multi-function cordless telephone 100 is determined by the operator, not the unspecified user, to set the type in the setting mode. To this end, the multifunction wireless telephone of the present invention operates largely divided into a 'setting mode' and a 'execution mode'.

[Setting Mode Operation]

5A and 5B, when the operator presses the set button of the key input unit 108 and lifts the handset, the hook switch detection unit 116 generates a hook-off signal and provides it to the control unit 110 (501 and 502). When the hook-off signal is input from the hook switch detection unit 116, the controller 110 switches to the 'setting mode' by the setting button signal of the key input unit 108 previously input, and then sets the setting keyword (eg, '# * #'). ', Etc.) is input (503). If the setting keyword signal is input through the card reader unit or the dialing number key, the control unit 110 recognizes that the numbers corresponding to the number key signal are the setting signals, and then temporarily stores them in the internal memory of the control unit 110 and then FIG. 5B. Perform the procedure shown in

If the setting password is input while the setting keyword signal is not input, the controller 110 temporarily stores the password in the internal memory (504). Then, it is determined whether the setting password has already been stored in the memory 104, and if the setting password is not stored, the temporarily stored setting password is stored in the memory 104, and the password is set and returned (505 to 507). .

If the setting password is already stored in the memory, the setting password temporarily stored in the internal memory of the controller 110 and the setting password previously stored in the memory 104 are not matched. Display "error / re-entry request" on the display unit 102, and if the setting password matches, delete the setting password stored in accordance with the special function input to the memory 104, and input the new setting password to process the setting password change procedure (508-512).

On the other hand, if a setting keyword (# * #, etc.) is input in step 503, after performing password authentication for setting, the input setting keyword is determined, and if it is the keyword 'access number setting', the dialing number is recognized and changed. The auto dialing number is received and temporarily stored in the internal memory of the control unit 110 (520 to 523).

Then, it is determined whether the automatic dialing number corresponding to each service access button is stored in the memory 104, and if not, the stored automatic dialing number is stored in the memory 104 corresponding to the access button and then returned. If it is stored, the corresponding autodial number of the memory 104 is deleted, and the new autodial number stored temporarily in the control unit 110 internal memory is returned and returned (524 to 526).

If the set keyword is determined in step 521 and the keyword 'type change' is used to select the type, the controller 110 selects the type corresponding to the input keyword and returns to the type (527,528).

[Run mode operation]

After the setting is completed, if it is used by unspecified users, the operation mode is as follows.

Figure 6 is a flow chart showing the run mode operation of the multifunction wireless telephone according to the present invention.

Referring to FIG. 6, when the handset is hooked off while the setting button is not input, the controller 110 proceeds to the execution mode and determines whether the currently set operation state is a “direct type” or a “multifunction type” ( 531,532). The determination of these two types of operation can be known by the control unit 110 reading the setting value of the execution mode stored in the memory 104 when the user lifts the handset. That is, the control unit 110 reads a signal of a predetermined type from the two types from the memory 104 and reads "Direct TYPE (TYPE which sends an intelligent network service access number directly, for example, a receiver" "or" Multi-function TYPE (User service). Select a connection number) (601, 602).

If the determination result is the direct type, the control unit 110 reads the access number corresponding to the preset intelligent network service identification number stored in the memory 104 when the user lifts the handset and transmits the access number to the DTMF generation unit 112 (603, 604). .

If the determination result is a multi-function type, the card reader 106 reads the card or the service identification number is input by the user's access button operation, and the access number corresponding to the service identification number is read out from the memory 104 and the DTMF generating unit ( 112) (605, 606).

Subsequently, the DTMF generation unit 112 generates a DTMF signal corresponding to the service access number and provides the DTMF signal to the transceiver 114, and the transceiver 114 transmits the DTMF signal corresponding to the service access number to the mobile communication module 118. By forming a wireless LOOP with the originating base station 202 through the primary network to configure the communication path with the intelligent network switch 206 (607, 608).

When the service access number is connected to the intelligent network, an announcement corresponding to the corresponding service is transmitted. In general, a service using a card requires input of a card, a card number or a password, and a collect call service. A request is made (609).

Thereafter, the controller 110 waits whether each dialing number key is input from the key input unit 108 or a signal is input to the card reader unit 106, and the user uses a card reader or a number key according to the announcement. When a password or the like is input, the DTMF generator is controlled to generate a DTMF signal corresponding to the input key, and the generated DTMF signal is transmitted to the intelligent network switch via the transmitter and receiver and the mobile communication module (610).

Accordingly, the intelligent network switch performs a predetermined authentication procedure using a card number / password and then broadcasts the incoming call number input if the authentication is successful (611, 612).

When the user inputs the called number by pressing the dialing number key according to the announcement, the controller 110 recognizes the corresponding numbers as the called party's phone number and controls the DTMF generator 112 to generate a DTMF signal corresponding to the input signal. (613). Thereafter, the DTMF signal generated by the DTMF generator 112 is transmitted to the transceiver 114, and the transceiver 114 transmits a DTMF signal corresponding to the called number through the mobile communication module 118 to the originating base station 202. A wireless LOOP is formed to form a call path consisting of a mobile communication network, an intelligent network exchange, a destination exchange, and a destination telephone (614).

On the other hand, if the collect call service in step 609, the intelligent network requests the incoming number, and the user enters the called number accordingly to connect with the called party for the collect call authentication. If the called party allows the collect call, the call path is continuously connected between the caller and the called party so that the call can be made (621 to 623).

When the call is completed and the handset is placed, the hook switch detection unit notifies the control unit of the hook-on state, and the control unit requests the call release to the network side to release the connection.

Subsequently, the entire process of providing an intelligent network telephone service using the multifunctional wireless telephone of the present invention configured and operated will be described as being divided into a service using a card and a collect call service.

[Example of operation of card service]

6 is a flowchart illustrating an example of providing an intelligent network service using a card according to the present invention.

When the user lifts the handset of the multi-function cordless telephone, the direct type is automatically connected to a specific service access number, and in the case of the multi-function type, the user presses an access button to request the service using the card. Accordingly, the multifunction wireless telephone attempts to connect to the intelligent network switch by transmitting the access number corresponding to the service requested by the user to the network side.

That is, when a call request occurs, the multifunction wireless telephone sends this signal and requests channel allocation from the originating base station within the effective range in the area where the call is generated. The base station then assigns a radio communication channel to the phone requesting channel assignment. Accordingly, the phone that is assigned a channel by making a call automatically dials the corresponding access number of the intelligent network communication product that the user wants, and is connected to the intelligent network through the public network, and the response ARS message from the intelligent network is delivered to the user. Will be formed.

Next, the user hears the ARS message transmitted from the intelligent network, and dials through the dialing number key or reads the card through the card reader unit according to the authentication procedure required by the intelligent network, and passes the card number or password to pass through the authentication procedure.

If authentication is successful, dial the incoming phone number to be called according to the guidance of the intelligent network, and the intelligent network sends out the number requested by the user through the public network. This allows the caller and the called party to talk. At this time, the communication cost according to the call is charged using the card.

[Example of operation of collect call service]

7 is a flowchart illustrating an example of providing a collect call service according to the present invention.

When the user picks up the handset of the multi-function cordless telephone, the direct type automatically connects to a specific service access number. In the multi-function type, the user presses a connection button to request the collect call service. Accordingly, the multifunction wireless telephone transmits the access number corresponding to the collect call service requested by the user to the network side and connects with the intelligent network switch.

The intelligent network switch notifies the collect call service through the ARS and requests the incoming telephone number. Accordingly, the user inputs the incoming telephone number. The intelligent network switch performs a call processing procedure, accesses the called telephone number, announces that a collect call has arrived through the ARS message, connects the caller and the called party for a while, and then checks whether the call is allowed. If the called party confirms the caller and then accepts the collect call, the caller and the called party can be connected and talked, and the caller is charged for the call time.

As described above, according to the present invention, after installing a multifunctional wireless telephone that can be used by an unspecified number using a mobile communication network in an environment where it is difficult to install a wired line such as a mountain wall or a military unit, a prepaid card, a postpaid card or a credit card. By using an intelligent network service such as a collect call service and a collect call service, an intelligent network service provided by a main communication service provider can be conveniently used at a low cost. Particularly, according to the present invention, a multi-function cordless telephone is a direct type or a handset that is directly transmitted by a preset intelligent network service access number when a handset is picked up or a handset is pressed by a connection button corresponding to a card or a corresponding intelligent network product or a service identification number through a card reader unit. Multi-function type that reads automatically can be set and various auto dialing methods can be used as needed.
