Abstract

A dialing method and device are disclosed. The method includes: a terminal acquiring dialing auxiliary data information, wherein, the dialing auxiliary data information comprises home location information and/or roaming location information; after receiving a dialed number of a subscriber, the terminal judging whether the dialed number conforms to a dialing rule according to the dialing auxiliary data information; and in a case that the terminal judges that the dialed number does not conform to the dialing rule, correcting the dialed number, and calling out the corrected dialed number. With the method and device, a problem of a higher network call loss rate in the related art is solved, a dialing success rate of the subscriber is increased, and the user experience is improved.

Claims

1. A dialing method, comprising:

when the terminal roams, the terminal querying a Local IDD Prefix and DDD Prefix according to a MCC registered when a position of the subscriber updates;

after receiving a dialed number of a subscriber, the terminal judging whether the dialed number conforms to a dialing rule according to the dialing auxiliary data information, comprising;

in a case that the terminal performs dialing in a home location and a length of the dialed number is greater than a length of a domestic direct dialed number, the terminal judging whether the dialed number conforms to the dialing rule according to the home location information of the terminal;

in a case that the terminal performs dialing in a roaming location, the terminal judging whether the dialed number conforms to the dialing rule according to roaming location information of the terminal; and

in a case that the terminal judges that the dialed number does not conform to the dialing rule, correcting the dialed number, and calling out the corrected dialed number.

2. 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 dialing auxiliary data information after receiving the dialed number of the subscriber comprises:

after the terminal receives the dialed number of the subscriber, judging whether an auxiliary dialing switch is ON;

in a case that the terminal judges that the auxiliary dialing switch is ON, judging whether the dialed number conforms to the dialing rule according to the dialing auxiliary data information; and

in a case that the terminal judges that the auxiliary dialing switch is OFF, calling out the dialed number.

3. 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 home location information of the terminal after receiving the dialed number of the subscriber comprises:

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:

in a case that the dialed number begins with the IDD Prefix of the roaming location and/or begins with the country code of the roaming location, the terminal correcting the dialed number according to the dialing rule of the domestic direct distance dialing of the roaming location;

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 of the roaming location.

9. The method according to claim 8, 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.

10. A terminal, comprising a processor configured to:

acquire dialing auxiliary data information, comprising;

acquiring home location information registered when a subscriber opens an account, which comprises a Mobile Country Code, MCC, an International Direct Dialing Prefix, IDD Prefix, and a Domestic Direct Dialing Prefix, DDD Prefix, and querying a Local IDD Prefix and DDD Prefix according to a MCC registered when a position of the subscriber updates, when the terminal roams;
