When power is supplied to the user terminal 300 and is operable, when a user inputs a predetermined signal by operating a keypad, the input key signal is input to the controller 320 through the user interface 310 (S100).

The signal determination unit 321 of the control unit 320 analyzes the input key signal to determine whether the key signal is a phone number, a search word for receiving predetermined content, or a signal based on a shortcut key for internet access. (S110).

In detail, when a key signal, that is, an input word is input, the signal determination unit 321 first determines whether the input word is a number. If the input word is all numbers, or if it contains numbers and certain symbols (for example, *, #, P (where P is a symbol for Pause, not English letter P)), it is determined that the input word is a phone number. In this case, when the input word is composed of three digits, it is determined that the telephone number is "114", "119", etc., and when the input word is composed of seven or more digits, it is determined that the input word is "7000600". If it includes a specific symbol, it is determined that the number is symmetrical with the specific telephone number such as "* 88", "## 114", and "** 114".

As a result of the determination, when the input key signal is a telephone number, the first processing unit 322 calls the telephone number input through the communication unit 330 (S120 to S130). The process of making a call according to the communication between the communication unit 330 and the mobile communication system (not shown) is already known, and a detailed description thereof will be omitted.

If the key signal input in step S120 is a search word, the second processor 323 performs internet access through the communication unit 330. In detail, the second processor 323 connects to the search system 100 through the communication unit 330 and then requests a search while providing a search word input by the user (S140 to S150). Accordingly, the search server 20 of the search system 100 searches for an external system connected through the database server 10 and / or the network 200 of the own system based on the search word provided from the user terminal 300, and Search for the content corresponding to the search word (S160).

At this time, the search server 20 detects a standard of the terminal based on a terminal identification number (such as a wireless telephone number of the terminal or a separate number assigned to the terminal itself) input from the user terminal 300, and then detects the specification of the terminal. Based on the standard, the content corresponding to the search word and formed in a format suitable for the standard may be found. In this case, the method for detecting the terminal specification is stored in the database server 10 of the retrieval system 100 for each terminal identification number based on this information, or received from the mobile communication system 100 (not shown) Can be performed based on information.

In addition, the search server 20 may perform a search operation only when the terminal is a user registered in the system based on the information stored in the user database 12 of the database server 10.

As described above, the searched content is transmitted to the user terminal 300, and the content corresponding to the search word received through the communication unit 330 is processed by the fourth processing unit 325, and then the display unit 340 is rotated. Displayed through (S170 to S180). In this case, the search server 20 may provide only the content list according to the search result, and then transmit detailed information about the selected content when the user selects the predetermined content. Accordingly, the user may receive various information corresponding to the search word only by inputting the search word without a separate access function on the terminal 300.

On the other hand, when the additionally input key signal corresponds to a shortcut key for Internet access, the second processing unit 323 may perform a connection to the corresponding site based on the Internet address (URL, etc.) set in the shortcut key.
