For example, a URL (Uniform Resource Locator) of a specific site may be transmitted to the counterpart using SMS.

In other words, any mobile communication terminal supporting a wireless Internet function such as WAP is connected to the other side by sending an SMS push message to the other party while being connected to the wireless Internet such as WAP. A message is an SMS that transmits a URL including a URL of a specific site in an SMS field and sends the message to a specific URL when the other party selects the corresponding SMS.

Accordingly, the mobile communication terminal of the other party receives the SMS push message from the sender while connected to the wireless Internet such as WAP, and simply informs the other party that the corresponding SMS has arrived through the icon, or the received message. The SMS push message is displayed on the screen and displayed to induce a connection to a specific URL in the received SMS push message.

As such, in the related art, a mobile communication terminal supporting a wireless Internet function such as WAP merely performs a display for notifying a user of receiving an SMS push message or inducing a connection to a specific URL in the SMS push message. There was no function to automatically conduct a call with the other party who sent the SMS push message. In other words, to perform a call with the other party who sent the corresponding SMS push message, the user must exit the currently running WAP application, find and display the other party's phone number, and then press the Send key. There was an inconvenience.

Alternatively, the method for answering a call in a mobile communication terminal according to an embodiment of the present invention may include: checking whether a current data traffic state is connected when the network is not the SVD capable network; Generating and transmitting a release command to the base station when the data traffic is connected, and backing up and storing the IP address and port number of the WAP server currently connected; Receiving the response message for the release command through the base station to terminate the data traffic; Confirming a reply telephone number in the SMS message and attempting to make a voice call to perform a voice call with the counterpart corresponding to the reply telephone number; And reconnecting the WAP server with the backed up IP address and port number to display the WAP screen at the end of the voice call to perform WAP surfing.

In another embodiment, the method for answering a call in a mobile communication terminal may include: checking whether the mobile communication terminal is in a doorment state when the data traffic is not connected; In the case of the doorment state, backing up an IP address and a port number of a currently connected WAP server; Confirming a reply telephone number in the SMS message and attempting to make a voice call to perform a voice call with the counterpart corresponding to the reply telephone number; And reconnecting the WAP server with the backed up IP address and port number to display the WAP screen at the end of the voice call to perform WAP surfing.

In addition, in the mobile communication terminal according to an embodiment of the present invention, when the call is not in the doorway state, the current WAP screen is caught and stored, and the call back number in the SMS message is confirmed and voiced. Attempting to place a call; And performing a voice call by calling the counterpart corresponding to the reply telephone number, and displaying the WAP screen at the end of the voice call.

According to the present invention, when a wireless Internet capable mobile communication terminal receives an SMS push message while data traffic is being connected, it is desired to perform a call to the other party who sent the SMS push message. After checking the traffic and data traffic conditions, the system automatically makes a call to the return telephone number of the sender of the SMS push message.

For example, in the present invention, a mobile communication terminal receives an SMS push message in a WAP connection using current data traffic in a network supporting only one traffic (that is, data only traffic or voice only traffic). In this case, after confirming that the field of the SMS push message includes the reply telephone number, the user can automatically dial the reply telephone number using the send button without exiting the WAP application.

For another example, the present invention provides a WAP using a current data traffic by a mobile communication terminal in a network supporting traffic capable of voice and data simultaneously (ie, a network supporting voice and data traffic). When an SMS push message is received while connected, voice reply can be made to a reply telephone number included in the SMS push message through a specific key without closing the WAP application. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the mobile communication terminal according to an exemplary embodiment of the present invention, a network for answering a call is a network supporting only one traffic (that is, traffic capable of only data or voice only) or traffic capable of simultaneously enabling voice and data. As a network, as shown in FIG. 1, the configuration includes a plurality of mobile communication terminals 11 and 12, a base station 20, a switch 30, and a push SMS server, which support a wireless Internet function such as WAP. 40 and the WAP server 50. Here, the corresponding voice and data traffic support means a service that enables voice and data at the same time by loading a multi application (voice or data) on one traffic channel.

In addition, in the mobile communication terminal according to an embodiment of the present invention, a network for answering a call is a counterpart that transmits the corresponding SMS push message after the receiving mobile terminal receives the SMS push message while the data traffic is being connected. If the user wants to make a call with the recipient, the recipient's automatic dialing checks the current network conditions and data traffic conditions, and then automatically dials the telephone number of the mobile terminal that sent the SMS push message. It is done to be.

Referring to the flowchart of FIG. 2, a method for answering a call in a mobile communication terminal according to an embodiment of the present invention is as follows.

First, in any mobile communication terminal (hereinafter, referred to as a first mobile communication terminal 11) that supports a wireless Internet function such as WAP, the wireless network such as the WAP server 50 is passed through the base station 20 and the switch 30. If you want to connect to the Internet server and have the other party (hereinafter referred to as the second mobile communication terminal 12) move to a specific site while surfing the WAP while connected to the wireless Internet such as WAP, the push SMS server Sending the URL of the specific site and the like to the second mobile communication terminal 12 using the SMS through 40, in which the URL and the return phone number of the specific site are included in the SMS field. When the 12 selects the corresponding SMS field, an SMS push message that leads to the URL of the specific site is generated and transmitted to the corresponding second mobile communication terminal 12.

Accordingly, the second mobile communication terminal 12 (that is, the receiving side mobile communication terminal) connects to a wireless Internet server such as the WAP server 50 via the base station 20 and the switch 30, and executes a WAP or the like. Check whether there is an SMS push message received from the first mobile communication terminal 11 (that is, the transmitting mobile terminal) via the base station 20 and the switch 30 while being connected to the same wireless Internet. (Step S21).

Accordingly, when the SMS push message is received, the second mobile communication terminal 12 notifies the user (ie, the recipient) of the reception of the SMS push message through an icon, or the received SMS push message. Is displayed on the screen and displayed to induce a connection to a specific URL in the received SMS push message, and at the same time, it is checked whether the current network is capable of supporting SVD (Simultaneous Voice and Data).

If the network is capable of SVD support in the twenty-second step S22, the second mobile communication terminal 12 is a specific key which is preset without the receiver terminating the WAP application while connected to the wireless Internet. By generating the event of the specific key, the current WAP screen is caught and stored as the catch data through the occurrence of the event of the specific key, and at the same time, the return telephone number included in the received SMS push message is received. After confirming, a voice call origination (Voice Call Origination) is attempted to the exchange 30 through the base station 20 (step S23).

Then, the exchange 30 checks the reply telephone number according to the voice call origination attempt received through the base station 20, and then calls the first mobile communication terminal 11 corresponding to the confirmed reply telephone number. To enable a voice call (step S24).

After that, when the voice call with the first mobile communication terminal 11 ends (step S25), the second mobile communication terminal 12 displays the WAP screen again so that the user can continue surfing the WAP again. (Step S26).

On the other hand, in the case of the network that does not support the SVD support in step 22 (S22), that is, a network that supports only one traffic (that is, only data traffic or voice traffic only), the second mobile communication terminal ( 12 checks the current data traffic state to confirm whether the current data traffic is connected (step S27).

At this time, if the current data traffic is connected in the 27th step (S27), the second mobile communication terminal 12 generates a release command for terminating the current data traffic to the base station 20 It transfers and backs up the IP address and port number of the WAP server 50 to an internal storage area (step S28).

Thereafter, the second mobile communication terminal 12 receives the response message for the release command through the base station 20 to terminate the data traffic (step S29), and thus within the received SMS push message. By checking the reply telephone number included, the voice call is attempted to the exchange 30 through the base station 20 (step S30).

Then, the exchange 30 checks the reply telephone number according to the voice call origination attempt received through the base station 20, and then calls the first mobile communication terminal 11 corresponding to the confirmed reply telephone number. To enable a voice call (step S31).

After that, when the voice call with the first mobile communication terminal 11 ends (step S32), the second mobile communication terminal 12 restarts the WAP server 50 using the IP address and port number which have been backed up. By connecting (step S33), the operation of the 26th step (S26), that is, the WAP screen is displayed again so that the user can continue surfing the WAP again.

On the other hand, if the current data traffic is not connected in the 27th step (S27), the second mobile communication terminal 12 checks whether the current network condition (Dormant State) (step S34) ). Here, the doorment state is a situation in which there is no allocation of air traffic (that is, radio frequency (RF) resource) between the base station 20 and the second mobile communication terminal 12. A protocol beyond PPP is a living data state.

Accordingly, when the current network condition is in the doorment state in the 34 th step S34, the second mobile communication terminal 12 immediately backs up the IP address and port number of the WAP server 50 currently connected. After the reference (step S35), the operation of the thirtieth step (S30), that is, to check the reply telephone number included in the received SMS push message to send a voice call to the corresponding reply telephone number to the base station 20 Through the operation to try to the exchange 30 side through.

On the other hand, when the current network condition is not in the doorment state in the 34 th step S34, the second mobile communication terminal 12 catches the current WAP screen and stores it as catch data and simultaneously receives the received WAP screen. After checking the reply telephone number included in the received SMS push message, the voice call is attempted to the exchange 30 through the base station 20 (step S36).

Then, the exchange 30 checks the reply telephone number according to the voice call origination attempt received through the base station 20, and then calls the first mobile communication terminal 11 corresponding to the confirmed reply telephone number. To enable a voice call (step S37).

After that, when the voice call with the first mobile communication terminal 11 ends (step S38), the second mobile communication terminal 12 displays the operation of the 26th step (S26), that is, the WAP screen again. Allow the user to continue surfing the WAP again.

As described above, when the wireless Internet terminal supporting the wireless Internet function such as WAP is received by the present invention when the SMS push message is received while being connected to the wireless Internet, an automatic call is made to the SMS reply number in the SMS push message. By doing so, it is possible to make a call without terminating the WAP application even when data traffic is currently in use.
