Referring to Figure 1, the present invention is a communication between the wireless terminal A, B (200, 202), wired telephones A, B (300, 302) personal computer 400 via the communication system 10 as a medium.

The wireless terminal A (200), B (202) and landline telephones (A) (300), (B) 302 have a display and input function for a text call, and a key having a function for selecting a text call and a voice call. It is preferable to have a.

In addition, the personal computer 400 also has a system specification such as a modem for text and voice calls over the Internet, and an Internet connection function. (Not shown) may be used to implement a text call and voice call using a browser or application program.

In addition, the communication system 10 includes a plurality of base stations A and B 122 and 124 forming a communication path for wireless communication of a terminal, a switch 120 for establishing a connection (set as an interval call) between base stations, and a short message. Packet network switching equipment 110 for the exchange of packets such as messages or text calls, wired network switch 140 for relaying wired calls, wireless network switch 112 for relaying wireless calls, and text calls over the Internet connected to the Internet. And an additional device 130 which is a server on which a matching program for relaying a voice call is mounted.

Here, the switch 120, the wired network switch 140 or the additional equipment 130 is configured to differently constitute a packet communication path for packet communication of data such as text and a circuit communication path for circuit communication of general voice and video. The packet call path is configured to pass through the packet network switching equipment 110, and the circuit call path is configured to pass through the wireless communication network switch 112.

By the above configuration, the text call service according to the present invention may be implemented as shown in FIG. 2.

First, a method for implementing a text call service between the wireless terminal A 200 and the wireless terminal B 202 will be described with reference to FIG. 2.

The call between the wireless terminal A 200 and the wireless terminal B 202 may be divided into a case in which one side requests a voice call and a case in which a text call is requested. This may be divided into a case of rejecting and a case of rejecting, and may be divided into a case of rejecting and a state of responding in case of requesting a text call.

That is, when the wireless terminal A 200 requests a call with the wireless terminal B 202 as a relay of the base station A 122 (S2), the switch 120 determines whether it is a voice call or a text call (S4, S6). .

When the switch 120 is a voice call, the switch 120 attempts a voice call according to the relay of the base station B 124 using the wireless communication network switch 112, and when the wireless terminal B 202 answers (S12), configures a voice call path. do. If it is determined that the wireless terminal B 202 does not answer, the switch 120 checks whether the wireless terminal B 202 requests a text call (S16).

At this time, the text call request may be performed by pressing the corresponding text call button set in the wireless terminal B (202). If the text call request or the call is not answered, the function call (such as not receiving a voice message) is performed. (S26).

When the switch 120 is confirmed that there is a text call request from the wireless terminal B (202), the wireless terminal to send a text call request message ("I want a text call to personal circumstances now. Press the text call button if possible", etc.) Transmitted to A (200) (S18).

When the wireless terminal A (200) side checks the text call request message and presses a corresponding button (S20), the switch 120 is a text call using the packet network switching device 110, that is, the wireless terminal A (200) and the wireless terminal B Configure a two-way call path between the (202).

If the wireless terminal A (200) side checks the text call request message and does not press the corresponding button (S20), the switch 120 guides the message to the wireless terminal B (202) side ("Now I cannot make a text call for personal reasons"). "Please contact me again later if possible", etc.).

In this way, it is possible to configure a voice call or switch to a text call according to the voice call request.

On the other hand, when the switch 120 determines that the wireless terminal A (200) wants a text call (S6), using the packet network switching equipment 110 attempts a text call according to the relay of the base station B (124), wireless When the terminal B 202 responds (S32), it forms a text call path. If it is determined that the wireless terminal B (202) is not responding, the switch 120 informs the wireless terminal A (200) of a message ("You cannot make a text call for personal reasons. Please contact us again later if possible.") ).

This can be configured as a text call according to the text call request.

On the other hand, unlike the embodiment of Figure 2, as shown in Figure 3, one direction may be a two-way communication path to make a text call and the other direction a voice call.

Referring to FIG. 3, if there is a call request from the wireless terminal A 200 (S100), the switch 120 checks whether it is a voice call request (S102).

When a voice call is required (S102), the switch 120 attempts a voice call with the wireless terminal B 202 using the wireless communication network switch 112 (S104), and if the mobile terminal B 202 answers (S106). A voice call path is configured between the wireless terminal A 200 and the wireless terminal 202 (S108).

If the mobile terminal B 202 selects a text call in response to the voice call attempt (S110), the switch 120 sends a guide message ("I have now selected a text call for personal reasons") (S112). And if you check in the wireless terminal A (200) using a voice call path from the wireless terminal A (200) to the wireless terminal B (202) and a text call path from the wireless terminal B (202) to the wireless terminal A (200) A dual channel is configured (S116). If the check is not made in the wireless terminal A (200) in step S114 transmits a guide message ("cannot make a call in personal circumstances. Please contact me again later").

In contrast, when the mobile terminal A (200) requests a text call is made a character call attempt (S120), the switch 120 is a wireless terminal B (202) in response to a text call (S122) packet network switching equipment 110 To configure a text call path using (S124).

In addition, in step S122, if the wireless terminal B 202 selects the voice call without responding to the text call (S126), the switch 120 transmits a guide message ("I have selected the voice call for personal reasons"). And if confirmation is made in the wireless terminal A (200) (S128) and configures a text call dual call path from the wireless terminal A (200) to the wireless terminal B (202) (S116). That is, a dual call path is configured by using a text call path from the wireless terminal A 200 to the wireless terminal B 202 and using a voice call path from the wireless terminal B 202 to the wireless terminal A 200 (S116). ). If the check is not made in the wireless terminal A (200) in step S130 transmits a guide message ("I can not talk to personal circumstances. Please contact me again later").

As shown in FIG. 3, a voice call, a double call, or a text call may be selected according to the situation of the wireless terminals A and B according to the intention of the manufacturer.

The embodiment according to the present invention has been described with respect to the configuration of the communication path between the wireless terminal A (200) and the wireless terminal B (202), but if you understand the technical content of the present specification, wired telephone A (300) and wired telephone The configuration of the call path between the B 302 and the first computer 400 connected to the Internet can be applied as in the embodiment.

In addition, the wireless communication network switch 112 used to construct a voice call path may transmit an image. Therefore, the video communication may be configured in parallel.

Meanwhile, in order to implement an embodiment of the present invention, an active window for a text call may be configured in a wireless terminal, a landline phone, or a personal computer as shown in FIGS. 4A to 4D.

In the active window used in the present invention, as shown in FIG. 4A, the other party's character window 500 in which the other party's character is displayed and the user's text window 502 in which the character entered by the user is displayed are divided, and the other party's phone number is divided into separate areas. The auxiliary window 504 may be configured to display special characters or functions required for text input. In addition, the active window may be composed of a joint text window 510 for displaying the contents input by time difference, an input window 512 for displaying the contents currently input by the user and the auxiliary window 504 as shown in FIG. 4B.

Alternatively, the video window 506 may be added to the active window configuration example of FIG. 4A, or the video window 516 may be added to the active window configuration of FIG. 4B. Therefore, communication can be made more freely while checking the screen displayed on the image window 516.

In addition, an embodiment according to the present invention may be configured such that a character input by the user for each screen may be transmitted in a predetermined time or in real time.

Therefore, according to the present invention, a user who has a limitation on a normal voice call, such as a deaf person, may use a real-time call using a text call, and a general subscriber uses a voice call when he / she wants to call in various education, meetings, or public places In case of difficulty, real time call can be used.
