Description

CHARACTER SERVICE METHOD AND SYSTEM FOR MOBILE TELECOMMUNICATION TERMINAL EQUIPMENT}

The present invention relates to a text service technology of a mobile phone, and in particular, when a mobile phone user is in an environment that is inappropriate for listening to a voice, the voice service is changed to a real-time text service, and the caller is in an environment that is inappropriate for transmitting voice information. The present invention relates to a text service method and system for converting text information into a voice signal and delivering the same to a receiver.

Due to the nature of the mobile phone, the place of call is changed from time to time, which is often inappropriate to provide a voice service. For example, when one or both of the sender and the receiver are located in a noisy environment, such as a public place or a meeting place, it is difficult to listen to the other party's voice or output his or her own voice.

Therefore, the conventional mobile phone implements a short message service (SMS) or a text receiving service.

The SMS service means that when the other party is located in an area where the call is difficult or in an area where the service is impossible, when the caller stores a voice message or a phone number in the SMS mailbox, the other party returns to the serviceable area and the voice message or phone number. It is a service to check the back. In addition, the text receiving service is a service that enables the mobile phone to check the message when the other party sends a short message.

However, such a conventional SMS mailbox function cannot be used in real time, and there is an inconvenience that a receiver needs to check separately later. In addition, there is a problem that the text receiving service is also impossible to perform a real-time two-way service, and the information can be transmitted only in a specific direction allowed after a certain time has elapsed. In addition, since the type of service is determined unilaterally according to the caller's request, there is a flaw in that the receiver cannot provide an appropriate service.

Accordingly, an object of the present invention is to change the voice signal to a text service when the mobile phone user is in a situation where it is difficult to listen to the voice, and the text information transmitted by the user as a voice signal when the mobile phone user is in a difficult situation to speak. It is to provide a text service method and system of a mobile phone to change and service.

According to a first aspect of the present invention, a service is provided by changing a voice signal transmitted to a receiver side into a text or a text information transmitted from a caller side according to a situation in which a mobile phone user is in service.

According to the second aspect of the present invention, the base station is in charge of voice recognition and text recognition functions in order to prevent excessive load on the mobile phone.

The text service method of the mobile phone according to the present invention includes a first step of converting a voice signal transmitted to the user side into text information after confirming that a text information reception service request is generated by a user at a base station; After confirming that the text information transmission service request is generated by the base station, the base station recognizes the text in the form of image received from the user's mobile phone through a text recognizer and converts the original text signal to a counterpart through a voice converter. A second process; The third base station performs a voice call service after confirming whether both mobile phone users request the voice call service from the base station.

1 is an exemplary block diagram of a text service system of a mobile phone according to the present invention, as shown therein, a mobile phone 10 for transmitting a voice signal or text information according to a user's request; A base station 21 for transmitting a voice signal transmitted from the mobile phone 10 as it is or converting text information into a voice signal and transmitting the same; A base station 22 which transmits the voice signal transmitted from the base station 21 as it is or converts it into text information and transmits it; The mobile phone 30 receives the voice signal of the other party through the base station 22 as it is, or requests the text information service from the base station 22 and receives the text information. The operation of the present invention configured as described above is attached. A detailed description with reference to FIG. 2 is as follows.

When the user of the mobile phone 30 receives a call from the mobile phone 10 and performs a voice call or is in a situation where voice reception is difficult before the voice call is started, the user requests the text information service to the base station 22. The following describes the processing process.

At this time, the voice signal of the caller transmitted from the mobile phone 10 is processed in a predetermined form and transmitted to the base station 22. However, at this time, the base station 22 accepts the request of the user of the mobile phone 30 to perform a text information service.

That is, the base station 22 confirms that a text information service request is generated from the user of the mobile phone 30, and then transmits the voice signal received through the base station 21 after being transmitted from the mobile phone 10 to the voice recognizer 22A. By converting into text information, the converted text information is transmitted to the mobile phone 30 side and displayed on the display unit 30C, so that the user of the terminal 30 receives the voice signal transmitted from the counterpart as real-time text information. (S1-S3)

On the other hand, when the user of the mobile phone 10 is in a situation where it is difficult to transmit a voice signal, the following describes the processing procedure for the case of transmitting their intention as text information.

The user of the mobile phone 10 selects a text message mode by manipulating a key and then inputs text information corresponding to his / her intention by using a keypad or a separate text input device. An example using a touch screen type character input device 10C for inputting character information with a pen, such as a PDA, is shown.

The text input through the character input apparatus 10C is processed through a text image processing unit 10D into a simple image form such as a fax service, and then transmitted through the antenna ANT11. As such, the reason why the user processes the text written by the pen on the text input device 10C as a simple image without transmitting it as a text is to minimize the load of the mobile phone 10.

At this time, the base station 21 recognizes the text in the form of the image received from the mobile phone 10 as the corresponding character through the character recognizer 21A, and then converts the original voice signal through the voice converter 21B for transmission. In addition, the converted voice signal is transmitted to the mobile phone 30 through the base station 22, so that the user of the mobile phone 30 can recognize the intention of the other party as a voice as usual (S4-S6).

In the above description, the character base station 21A and the voice converter 21B are installed in the base station 21, and the voice base station 22A is installed in the base station 22 as an example. The voice / text conversion service and the text / voice conversion service described above can be performed.

Of course, in this case, the user of the mobile phone 10, 30 can freely select and use the transmission and reception mode. That is, the sender can receive voice or text information while transmitting voice or text information, and the receiver can similarly transmit voice or text information while receiving voice or text information.

On the other hand, when both mobile phone users are in an environment where there is no difficulty in making a voice call, the base station performs a voice call service for them.

That is, the voice signal output through the handset 10A of the calling party's mobile phone 10 is processed in a form suitable for transmission to the other party through the voice signal processor 10B and then transmitted through the antenna ANT11. The voice signal thus transmitted is transmitted to the other party's mobile phone 30 through the base stations 21 and 22, so that the voice signal of the caller can be listened to (S7).

Similarly, the voice signal transmitted from the receiver side mobile phone 30 is transmitted to the mobile phone 10 through the same path as described above. Accordingly, the users of the two mobile phones 10 and 30 can make voice calls.

As described in detail above, in the present invention, in the service of voice or text information at the base station, the service converts text information transmitted according to a caller's request into a voice signal, or converts text information received at the request of a receiver into text information. By converting the service to be able to service, even if the mobile phone user is in a difficult situation to talk, there is an effect that can service their intentions in real time. In addition, deaf and hearing impaired people also have the effect of enabling communication with the public.
