Abstract

A call error prevention method comprises the steps of inputting a call number, checking whether the input number is a recognizable call service code, determining whether the input number contains the same number of digits as a recognized call service code, and generating an input error warning if the input number does not contain the same number of digits as the recognized call service code.

Claims

1. A call error prevention method, said method comprising the steps of:

inputting a call number;

checking whether the input number is a recognizable call service code;

determining whether the input number contains the same number of digits as a recognized call service code; and

generating an input error warning if the input number does not contain the same number of digits as the recognized call service code.

2. The call error prevention method of claim 1, further comprising the step of placing the call if the input number is not a recognizable call service code.

3. The call error prevention method of claim 1, further comprising the step of placing the call if the input number contains the same number of digits as a recognized call service code.

4. The call error prevention method of claim 1, further comprising the step of re-inputting the call number to correct a call error.

5. A call error prevention method, said method comprising the steps of:

inputting a call number;

checking whether the input number is a recognizable call service code;

determining whether the input number contains the same number of digits as a recognized call service code;

generating an input error warning if the input number does not contain the same number of digits as the recognized call service code; and

checking whether a call is to be placed using the recognized call service code.

6. The call error prevention method of claim 5, further comprising the step of placing the call if the input number is not a recognizable call service code.

7. The call error prevention method of claim 5, further comprising the step of placing the call if the input number contains the same number of digits as a recognized call service code.

8. The call error prevention method of claim 5, further comprising the step of re-inputting the call number to correct a call error.

9. A call error prevention method, said method comprising the steps of:

inputting a call number;

checking whether the input number is a recognizable emergency call number;

determining whether the input number contains the same number of digits as a recognized emergency call number;

generating an input error warning if the input number does not contain the same number of digits as the recognized emergency call number; and

checking whether a call is to be placed using the recognized emergency call number.

10. The call error prevention method of claim 9, further comprising the step of placing the call if the input number is not a recognizable emergency call number.

11. The call error prevention method of claim 9, further comprising the step of placing the call if the input number contains the same number of digits as a recognized emergency call number.

12. The call error prevention method of claim 9, further comprising the step of re-inputting the call number to correct a call error.

13. A communication unit adapted to check an input call number against a store of recognizable call service codes, determine whether the input number contains the same number of digits as a recognized call service code, and generate an input error warning if there is a mismatch in the number of digits between the input number and the recognized call service code.

14. A communication unit adapted to check an input call number against a store of recognizable call service codes, determine whether the input number contains the same number of digits as a recognized call service code, generate an input error warning if there is a mismatch in the number of digits between the input number and the recognized call service code, and check whether a call is to be placed using the recognized call service code.

15. A communication unit adapted to check an input call number against a store of recognizable emergency call numbers, determine whether the input number contains the same number of digits as a recognized emergency call number, generate an input error warning if there is a mismatch in the number of digits between the input number and the recognized emergency call number, and check whether a call is to be placed using the recognized emergency call number.
