However, in reality, a mobile communication network requires a relatively expensive fee compared to a landline telephone because it requires installation of expensive equipment and wireless resource use for wirelessly transmitting and receiving voice and packet data.

Accordingly, in order to solve a user's burden, a method of accessing a wired telephone network using a mobile communication terminal equipped with an automatic call router (ACR) function has been proposed. By using the ACR function, the outgoing call of the mobile communication terminal is automatically connected to the called party's communication terminal through a wired telephone network, thereby enabling a charge of a wired telephone or a discounted mobile communication service.

Specifically, when a call is generated from a mobile communication terminal equipped with an ACR function, the mobile communication terminal first connects to a communication network (ie, a wired telephone network) provided by a separate communication service provider using a predetermined access number. Then, the mobile communication terminal enters the called party's telephone number after confirming the connection with the switch of the communication network provided by the separate telecommunication service provider using the passive standby function, or after being connected to the switch using the time standby function for a predetermined time. After this elapses, the called party's telephone number previously input is transmitted to the switch.

Therefore, the conventional wired telephone network connection method has a problem that it is possible only in a mobile communication terminal that provides a passive standby or time standby function. In addition, since the mobile communication terminal transmits the called party's telephone number after connecting to the switchboard of the communication network provided by the separate telecommunications provider, there is a possibility that an error occurs in the sending of the called party's telephone number and the call waiting time is long. There was this.

Accordingly, an object of the present invention is to provide a mobile communication terminal capable of call processing through automatic wired telephone network connection even if it does not support the manual standby and time standby functions, and a system for providing call processing using a wired telephone network to such mobile communication terminals and processing thereof.

However, the mobile communication terminal 110 according to an embodiment of the present invention provides a wired telephone network connection setting function. You can choose to handle all calls through your wired telephone network or to handle all calls through your mobile network. In addition, the mobile communication terminal 110 according to an embodiment of the present invention may be set to process the call through the wired telephone network 150 only for a specific incoming telephone number.

In particular, when the call connection request key is input, the mobile communication terminal 110 according to an embodiment of the present invention uses the packet network switch (hereinafter referred to as a 'called phone number') of the incoming terminal 190 as input. After transmitting to the ACR server 180 through the 140, the ACR switch 170 is accessed to request an outgoing call.

Specifically, the mobile communication terminal 110 is connected to the mobile switch 130 and the packet network switch 140 through the base station 120 for outgoing call processing. At this time, the mobile communication terminal 110 is actually connected to the mobile switch 130 after the connection to the packet network switch 140 is completed first.

As such, the mobile communication terminal 110 connected to the mobile switch 130 transmits a call processing request including the access number and the telephone number of the mobile communication terminal 110 (hereinafter, referred to as a "transmission telephone number"). do. In addition, the mobile communication terminal 110 connected to the packet network switch 140 transmits a request for storing the incoming telephone number to the ACR server 180.

The mobile exchange 130 receives the call processing request of the mobile communication terminal 110 and requests the call processing to the ACR switch 170 through the wired telephone network 150. At this time, the mobile switch 130 checks the access number included in the call processing request and transfers the call processing request to the switch of the corresponding communication network, that is, the ACR switch 170 connected to the wired telephone network 150. Here, the wired telephone network 150 includes a public switched telephone network (PSTN), that is, a public telephone network and an intelligent network connected to the public telephone network.

The packet network switch 140 receives the request for storing the incoming phone number of the mobile communication terminal 110 and transmits the request for storing the incoming phone number to the ACR server 180 through the data network 160. At this time, the packet network switch 140 confirms the access address of the ACR server 180 included in the incoming phone number storage request and delivers the incoming phone number storage request. Here, the data network 160 is a communication network capable of packet-based data transmission and reception, such as the Internet network.

When the ACR switch 170 receives a call processing request of the mobile communication terminal 110 through the wired telephone network 150, the ACR switch 170 connects to the ACR server 180 and connects the call to the mobile terminal 110 to which the call is to be connected. A phone number, that is, the called phone number information is obtained to connect a call between the mobile communication terminal 110 and the called terminal 190.

Specifically, as shown in FIG. 2, the ACR switch 170 includes a transceiver 171, an incoming phone number requester 172, a call processing determiner 173, and a call processor 174.

In this case, when it is determined that the call processing can be performed, the call processing unit 174 is connected to the mobile communication terminal 110 and the called terminal through a corresponding communication network according to the format of the obtained incoming call number data (ie, a communication method). 190 to connect the call between. For example, the call processing unit 174 processes a call connection with the called terminal 190 through the wired telephone network 150 when the obtained called number is a wired telephone number, and the obtained called number is a mobile communication terminal. In the case of the phone number, the call connection with the destination terminal 190 is processed through the mobile switch 130 located in the mobile communication network.

When the call processing unit 174 determines that the call processing cannot be performed, the call processing unit 174 notifies the mobile communication terminal 110 that the current call processing is not possible, and requests a voice message re-entering the incoming call number (ie, an automatic response). Message). At this time, the call processing unit 174 transmits the voice message to the mobile switch 130 through the circuit data channel.

 The ACR server 180 receives a request for storing the incoming phone number of the mobile communication terminal 110 through the data network 160, thereby receiving identification information (for example, a transmission phone number) and the current reception of the mobile communication terminal 110. Matched incoming phone number information and store it. The ACR server 180 then provides the currently stored incoming phone number data requested by the ACR switch 170. At this time, the incoming call number information included in the incoming call number storage request received by the ACR server 180 is incoming call number data or redial call notification data.

Specifically, as shown in FIG. 2, the ACR server 180 includes a transceiver 181, a reception response unit 182, a redial determination unit 183, a data storage unit 184, and a storage time changing unit 185. And a data processing unit 186.

The transceiver 181 receives the request for storing the incoming phone number of the mobile communication terminal 110 through the data network 160 and transmits it to the redial determination unit 183 and the data storage unit 184. The transceiver 181 transmits data generated from the reception response unit 182 and the data processing unit 186 to the mobile communication terminal 110 or the ACR switch 170. In this case, the transceiver 181 transmits data transmitted to the mobile communication terminal 110 through a packet data channel.

The reception response unit 182 determines whether the reception telephone number information included in the reception telephone number storage request has been successfully received, and transmits a reception success or failure response to the mobile communication terminal 110. At this time, the reception response unit 182 determines whether an error has occurred in the received incoming telephone number data and responds to the reception success or failure.

The redial determination unit 183 determines whether the incoming telephone number information included in the incoming telephone number storage request is the incoming telephone number data or the redial notification data, and transmits the result to the data storage unit 184. In this case, the redial determination unit 183 may determine the redial notification data in units of data length (bit) of the incoming telephone number information.

Specifically, the incoming call number data may be composed of a combination of a plurality of numeric data, and the redial call notification data may be composed of at least one text data. For example, when the redial notification data is composed of one piece of identification text data, the size of the incoming phone number data is relatively larger than that of the redial notification data, and thus, the redial notification unit 183 determines the redial notification data and the incoming phone number data. Can be distinguished.

The data storage unit 184 stores the identification information of the mobile communication terminal 110, that is, the transmission telephone number and the incoming telephone number data, when the incoming telephone number information included in the incoming telephone number storage request is the incoming telephone number data. To match.

 If the incoming call number information included in the incoming call number storage request is the redial call notification data, the storage time changing unit 185 matches the sending telephone number of the mobile communication terminal 110 stored in the data storage unit 184 to simulate the call. Change the storage time of the recently stored incoming phone number data to the current time and save it.

The data processor 186 matches the identification information of the mobile communication terminal 110, that is, the outgoing phone number, according to the incoming phone number request received from the ACR switch 170 through the transceiver 181, and is the most recently stored incoming phone. Deliver the number data to the ACR switch 170. At this time, the data processing unit 186 transmits the incoming telephone number response including the incoming telephone number data and the storage time information to the ACR exchange 170 in response to the incoming telephone number request.

Hereinafter, a mobile communication terminal capable of automatically connecting a wired telephone network according to an embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4.

3 is a diagram illustrating a configuration of a mobile communication terminal according to an embodiment of the present invention.

4 is a flowchart illustrating a method of automatically accessing a wired telephone network of a mobile communication terminal according to an embodiment of the present invention.

In this case, for convenience of description, a description of a general configuration and operation of a mobile communication terminal that is not strongly related to the features of the present invention will be omitted.

As shown in FIG. 3, the mobile communication terminal 110 includes an input unit 31, an ACR control unit 32, a storage unit 33, a transceiver unit 34, and a display unit 35.

The input unit 31 transmits call connection attempt generation information such as folder opening, slide up, or key data generation according to a keypad operation of the mobile communication terminal 110 to the ACR controller 32. For example, when the input unit 31 receives any one of a numeric key and a call connection request key (for example, a 'SEND' key) for inputting an incoming telephone number through a keypad, the input unit 31 receives a call. It is determined that an attempt to connect has occurred. In addition, when the call connection request key data is generated, the input unit 31 transmits the call connection request to the ACR controller 32.

When a call connection attempt occurs, the ACR controller 32 executes an ACR program stored in the storage 33 to perform an ACR procedure.

Specifically, when the call connection request key data is input in the state in which the ACR program is executed, the ACR control unit 32 receives the request for storing the incoming phone number including the received incoming phone number data through the transceiver unit 34. Transmit to 180. At this time, the ACR control unit 32 transmits the incoming telephone number storage request to the packet network switch 140 using the server of the designated communication service provider, that is, the ACR server 180 stored in the storage unit 33.

In addition, the ACR controller 32 checks the access number of the exchange of the specified communication service provider, that is, the ACR switch 170, stored in the storage 33, and transmits and receives a call processing request including the access number. It transmits to the mobile switch 130 of the mobile communication network through.

On the other hand, the ACR control unit 32 determines that the call processing request for redialing if the call connection request key is immediately input without inputting the telephone number key data while the ACR program is executed. The ACR control unit 32 generates the re-call notification data as the incoming call number information and transmits the incoming call number storage request to the ACR server 180 through the transceiver 34. In this case, the redial notification data may be generated as specific text data.

The storage unit 33 stores an ACR program for automatically connecting an outgoing call of the mobile communication terminal 110 to the wired telephone network 150. In addition, the storage unit 33 stores the access number of the ACR switch 170, which is the destination of the outgoing call of the mobile communication terminal 110, and access address of the ACR server 180, which is a destination for transmitting the incoming telephone number data. Is saving.

The transceiver 34 transmits the outgoing call and circuit or packet data of the mobile communication terminal 110 to the communication network under the control of the ACR controller 32, and transmits each data received from the outside to the ACR controller 32. .

At this time, the transceiver 34 transmits a call processing request generated from the mobile communication terminal 110 to the mobile switching center 130 through the base station 120, and transmits a request for storing the incoming telephone number through the base station 120. Transmit to 140.

In addition, the transceiver 34 transmits a response to the call processing request received from the ACR switch 170 to the ACR controller 32, and responds to a request for storing an incoming phone number received from the ACR server 180. To the ACR control unit 32.

The display unit 35 displays a service screen such as a call processing request result or an incoming phone number re-input request on the screen of the mobile communication terminal 110 under the control of the ACR controller 32.

On the other hand, the ACR control unit 32 according to an embodiment of the present invention may perform the call processing in response to the call processing request and the incoming call number storage request transmitted from the transceiver 34. At this time, the ACR control unit 32 transmits the call processing request to the ACR switch 170 after receiving the response to the incoming call number storage request transmitted to the ACR server 180.

For example, if the response of the ACR server 180 to the request for storing the incoming call number is failure to receive data or the response is not received within a certain period, the ACR controller 32 receives the call through the display unit 35 after the call ends. A screen for requesting to re-enter the phone number can be displayed.

In addition, the ACR control unit 32 according to an embodiment of the present invention outputs the voice message through an audio unit (not shown) when receiving a voice message containing the content of the call processing from the ACR switch 170, and the call You can exit.

Hereinafter, a call processing method through automatic wired telephone network connection of a mobile communication terminal according to an embodiment of the present invention will be described with reference to FIG. 4.

First, while driving the ACR program, the call connection request key is received (S401). At this time, when a call connection request such as key data generation or folder opening occurs in the standby state, ACR program driving starts.

Then, at the time of call connection request key data input, it is determined whether it is a general call or a redial call (S402). At this time, when the incoming call number key data is generated before the call connection request input key data is generated, it is determined as a general call, and when only the call connection request input key data is generated without the incoming call number key data input, it is determined as a re-call.

As a result of the determination in step S402, when the call connection request is a general call connection request, a call request for storing the called phone number including the called phone number data by accessing the data network 160 using the preset access address is performed through the packet data channel. To transmit (S403).

On the other hand, if the call connection request is a re-dial call connection request as a result of the determination in step S402, access to the data network 160 using the preset access address is used to store the incoming call number storing request including the redial notification data in the packet data channel. Through the transmission (S404).

Then, it is determined whether a storage success response of the data network 160 side to the incoming call number storage request is received within a predetermined time (S405).

As a result of the determination in step S405, when the storage success response is received within a predetermined time, the call access request including the transmission telephone number information is transmitted through the circuit data channel by accessing the wired telephone network 150 using the preset access number. The call connection with the called terminal is performed (S406).

On the other hand, if a predetermined time elapses or a failure response other than the storage success response is received as a result of the determination in step S405, a screen indicating a failure to transmit the called telephone number is output and the call is terminated (S407).

Hereinafter, a method of processing an outgoing call using a wired telephone network according to an embodiment of the present invention will be described in detail with reference to FIG. 5.

5 is a data flow diagram illustrating a call processing method using a wired telephone network according to an embodiment of the present invention.

As shown in FIG. 5, when a call connection request is input to the mobile communication terminal 110 (S501), the mobile communication terminal 110 accesses the ACR server 180 through the packet network exchange 140 and the data network 160. To transmit the incoming call number storage request (S502). In this case, the mobile communication terminal 110 accesses the data network 160 using the preset access address of the ACR server 180.

Then, the ACR server 180 stores the incoming telephone number data corresponding to the incoming telephone number information included in the incoming telephone number storage request by matching the transmitting telephone number and the storing time (S503), and stores the storage success response in the mobile communication. Transmission to the terminal 110 (S504).

The mobile communication terminal 110 receiving the reception success response transmits a call processing request by accessing the ACR switch 170 through the mobile switch 130 and the wired telephone network 150 (S505). At this time, the mobile communication terminal 110 connects to the wired telephone network 150 using the access number of the ACR switch 170 previously stored.

Then, the ACR switch 170 requests the incoming telephone number data to the ACR server 170 according to the received call processing request (S506). At this time, the ACR switch 170 transmits the incoming telephone number request including the outgoing telephone number according to the call processing request to the ACR server 180.

The ACR server 180 which has received the incoming telephone number request transmits the latest stored telephone number data and storage time information to the ACR switch 170 that matches the outgoing telephone number (S507).

The ACR switch 170 that receives the incoming phone number data transmits a call connection request to the corresponding called terminal 190 by using the incoming phone number data (S508). In this case, FIG. 5 shows that the ACR switch 170 immediately sends a call connection request to the called terminal 190. However, in practice, the ACR switch 170 transmits a call connection request to the called terminal 190 through the mobile switch 130 when the called terminal 190 is a mobile communication terminal, and when the called terminal 190 is a wired telephone, The call connection request is transmitted to the called terminal 190 through the telephone network 150.
