when a country corresponding to the target telephone number of the user terminal cannot be identified, the number analysis machine learning system checks pattern similarities with data stored in the country-specific telephone number system information database and displays a plurality of candidate countries on the screen of the user terminal or outputs the plurality of candidate countries by voice via the speaker of the user terminal.

8. The country-specific telephone number system analysis system according to claim 1 , wherein

the information regarding the international call service providers stored in the country-specific international call service provider information database comprises information of call charges to be incurred when a telephone call is made to a foreign country through each of the international call service providers.

9. A telephone call connection method which is performed by the country-specific telephone number system analysis system according to claim 1 , the telephone call connection method comprising;

(a) a step in which a user terminal attempts to make a telephone call to a target telephone number or transmit a text message to the target telephone number;

(b) a step in which the user terminal transmits the target telephone number to a telephone number system analysis logic server;

(c) a step in which the telephone number system analysis logic server checks whether the received target telephone number conforms to an international telephone number system protocol;

(d) a step in which the telephone number system analysis logic server identifies a country corresponding to the target telephone number when it is determined that the target telephone number conforms to the international telephone number system protocol;

(e) a step in which a number analysis machine learning system which has received the target telephone number from the telephone number system analysis logic server identifies a country corresponding to the target telephone number by accessing a country-specific telephone number system information database when it is determined that the target telephone number does not conform to the international telephone number system protocol; and

(f) a step of dialing the target telephone number in consideration of the country identified in the step (d) or (e), wherein

the step (f) includes:

selecting one of international call service providers whose information is stored in a country-specific international call service provider information database; and

dialing the target telephone number after adding a dial code of the selected international call service provider and a country code as prefixes before the target telephone number.

10. The telephone call connection method according to claim 9 , further comprising:

a step in which the user terminal or the telephone number system analysis logic server identifies a country corresponding to a telecommunications carrier to which the user terminal subscribes between the steps (a) and (b) or between the steps (b) and (c).

11. The telephone call connection method according to claim 10 , wherein

the identification of the country corresponding to the telecommunications carrier to which the user terminal subscribes is performed by checking a USIM chip.
