in a case that the dialed number begins with a Domestic Direct Dialing (DDD) Prefix of the home location plus an area code, and the length of the dialed number is a sum of the length of the domestic direct dialed number plus a length of the DDD Prefix plus a length of the area code, the dialed number conforming to a dialing rule of domestic direct distance dialing; or,
in a case that the dialed number begins with an International Direct Dialing (IDD) Prefix of the home location plus a country code, and the length of the dialed number is a sum of a length of an international direct dialed number plus a length of the IDD Prefix plus a length of the country code, the dialed number conforming to a dialing rule of international direct distance dialing; or,
in a case that the terminal judges that the dialed number does not conform to the dialing rule, the dialed number not conforming to the dialing rule.

4. The method according to claim 3 , wherein the step of correcting the dialed number in the case that the terminal judges that the dialed number does not conform to the dialing rule comprises:
in a case that the dialed number begins with the DDD Prefix of the home location and/or begins with the area code, the terminal correcting the dialed number according to the dialing rule of the domestic direct distance dialing; or,
in a case that the dialed number begins with other numbers, the terminal correcting the dialed number according to the dialing rule of the international direct distance dialing.

5. The method according to claim 4 , wherein the step of correcting the dialed number in the case that the terminal judges that the dialed number does not conform to the dialing rule comprises:
in a case that the dialed number begins with a non-numeric symbol, the terminal deleting the non-numeric symbol or replacing the non-numeric symbol with an array corresponding to the non-numeric symbol, and correcting the dialed number according to a beginning of the dialed number after the deletion or replacement.

6. The method according to claim 1 , wherein before the step of the terminal judging whether the dialed number conforms to the dialing rule according to the home location information of the terminal, the method further comprises:
in a case that the length of the dialed number is the length of the domestic direct dialed number, the terminal calling out the dialed number.

7. The method according to claim 1 , wherein the step of the terminal judging whether the dialed number conforms to the dialing rule according to the roaming location information of the terminal comprises:
in a case that the dialed number begins with a DDD Prefix of the roaming location plus an area code, and the length of the dialed number is a sum of the length of the domestic direct dialed number plus the length of the DDD Prefix plus the length of the area code, the terminal judging that the dialed number conforms to a dialing rule of domestic direct distance dialing of the roaming location; or,
in a case that the dialed number begins with an IDD Prefix of the roaming location plus a country code, and the length of the dialed number is a sum of the length of the international direct dialed number plus the length of the IDD Prefix plus the length of the country code, the terminal judging that the dialed number conforms to a dialing rule of international direct distance dialing of the roaming location; or,
in a case that the terminal judges that the dialed number does not conform to the dialing rule, the dialed number not conforming to the dialing rule.

8. The method according to claim 7 , wherein the step of correcting the dialed number in the case that the terminal judges that the dialed number does not conform to the dialing rule comprises:
