Hereinafter, with reference to the accompanying drawings will be described in detail the operating principle of the preferred embodiment of the present invention. In the following description of the present invention, detailed descriptions of well-known functions or configurations will be omitted if it is determined that the detailed description of the present invention may unnecessarily obscure the subject matter of the present invention. Definitions of terms to be described below should be made based on the contents throughout the specification.

The present invention described below is for connecting to a telephone number guide server using a short message interactive service and then inquiring and receiving a phone number through a short message. Here, the short message interactive service is a service that allows a mobile terminal to send and receive a short message to a specific information server of a message center and a point to point, and uses a paging channel instead of using a call channel. You can be provided with the desired information even without setting.

1 schematically shows the configuration of an entire system for guiding a telephone number using a short message service according to the present invention.

Referring to FIG. 1, the mobile terminal 20 communicates with the mobile communication network 10 through a wireless channel according to a predetermined standard. The mobile communication network 10 connects the mobile terminal 20 to another subscriber system, and transfers a short message received from the mobile terminal 20 to a message center (MC) 12 or the The short message received from the message center 12 is transferred to the portable terminal 20. The message center 12 enters into an agreement with a mobile communication service provider to support a short message interactive service. In particular, the telephone number guide server 14 requests a search to the guide material database 16 in response to a telephone number inquiry from the message center 12, and if a search result is received from the guide material database 16, the message center ( 12) to finally arrive at the mobile terminal 20.

2 shows a schematic block diagram of a portable terminal 20 to which the present invention can be applied.

Referring to FIG. 2, the control unit 26 controls the overall operation of the entire portable terminal 20 and performs an operation required for the phone number guide service according to the present invention. To this end, the control unit 26 includes a digital signal processor (DSP), a microprocessor and other circuits.

The storage unit 25 includes a read only memory (ROM), a random access memory (RAM) and a voice memory for storing a plurality of program codes and data executed by the control unit 26. The radio processor 21 includes a modulator, a transmit amplifier, a receive amplifier, and a demodulator, and exchanges radio signals with a mobile communication network including a base station and an exchange station. The voice processor 22 converts the voice data received from the wireless processor 21 into an audible sound through a speaker and outputs the voice signal received from the microphone under the control of the controller 26. Output to the processing part 21.

The display unit 23 may be formed of a liquid crystal display (LCD) or the like and displays various display data and characters generated in the portable terminal under the control of the control unit 26. The key input unit 24 includes a plurality of numeric / character input keys, function keys, keys for calling, etc., which allow a user to select a function, input data, and select a number.

3 is a flowchart illustrating a procedure for inquiring a telephone number using a short message service according to the present invention.

Referring to FIG. 3, when a user starts an interactive service by operating a menu key or a predetermined shortcut key of the mobile terminal 20, the mobile terminal 20 enters the interactive service mode in step S110. If the user does not request a phone number guide service in step S120, the mobile terminal 20 proceeds to step S130 to process the corresponding service.

When the user requests the phone number guide service in step S120, the mobile terminal 20 accesses the phone number guide server in step S140. Referring to step S140 in more detail, the mobile terminal 20 generates a short message including information requesting a phone number guide service and transmits the message to the phone number guide server 14 through the message center 12. The screen waiting for the response of the telephone number guide server 14 is displayed. When the short message including the search information input screen information is received from the telephone number guide server 14 through the message center 12, the mobile terminal 20 displays this. If necessary, the search information input screen information may further include guide phrases necessary for a phone number guide service. On the other hand, after the phone number guide server 14 transmits the search information input screen information, the mobile terminal 20 waits for receiving information for searching for a phone number.

In step S150, the portable terminal 20 displays the search information input screen. When the user inputs the search information for the desired phone number in step S160, the mobile terminal 20 generates a short message including the search information in step S170 and transmits it to the phone number guide server 14. . The search information may include at least one of a person's name, a business name, an address, and the like according to a format of the search information input screen which may be determined by the phone number guide server 14.

The telephone number guide server 14 receives the search information and requests a search from the guide data database 16. When the guide data database 16 performs a search and then responds to the search result, that is, the telephone number with the telephone number guide server 14, a short message including the found telephone number is generated and transmitted to the mobile terminal 20.

4 is a flowchart illustrating a procedure of guiding a telephone number using a short message service according to the present invention.

Referring to FIG. 4, in step S210, the mobile terminal 20 receives a short message in an interactive service mode for phone number guidance. Then, the mobile terminal 20 extracts the phone number included in the received short message in step S220 and displays it on the screen. Then, in step S230, the mobile terminal 20 inquires whether the phone number is a desired phone number. Display the menu. If the user does not recognize that the telephone number is to be guided, the mobile terminal 20 displays a screen for inquiring the user whether a call connection with the guide server is desired in step S280. If the user wants to connect the call in step (S290), the portable terminal 20 connects the call with the guide server so that the user can directly talk to the guide. On the other hand, if the user recognizes that the telephone number to be guided in step S230 proceeds to step S240.

In step S240, the mobile terminal 20 displays a screen for asking the user whether to store the phone number. If the user requires storage, then in step 250 the phone number is stored in an internal phone number database. If the user does not request storage or the storage of the telephone number is completed, the flow proceeds to step S260. In step S260, the portable terminal determines whether there is a call request from the user. If the user requests a call, step 270 automatically connects to the phone number.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.

In the present invention operating as described in detail above, the effects obtained by the representative ones of the disclosed inventions will be briefly described as follows.

The present invention can solve the difficulty of transmitting the search information by the voice inquiry during the telephone number inquiry and guidance, and the difficulty of storing or recording the telephone number. In addition, since the text message is transmitted without occupying the call, the cost can be reduced because the mobile communication network and the exchange do not occupy expensive traffic resources. In addition, the guide number can be automatically linked or stored, so there is no need to contact the same number again.
