In this case, network side is behind the dual-tone multifrequency sign indicating number that order received communication terminal sends, if the interval duration that receives adjacent dual-tone multifrequency sign indicating number is less than the interval duration threshold value of setting (for example the duration threshold value is made as 300 milliseconds at interval), then the dual-tone multifrequency sign indicating number that will receive in proper order is divided in the same dual-tone multifrequency code character, the interval duration of two adjacent dual-tone multifrequency sign indicating numbers that receive when order is during more than or equal to 300 milliseconds, these two adjacent dual-tone multifrequency sign indicating numbers are divided into different dual-tone multifrequency code characters, be the boundary promptly with these two adjacent dual-tone multifrequency sign indicating numbers, finish a last dual-tone multifrequency code character, begin next dual-tone multifrequency code character.
The device start DTMF that collects the digits that supposes network side collects the digits, and finishes to collect the digits to receive that " # " key table shows, establishing the time point of receiving first DTMF sign indicating number is 0, and its result that collects the digits is as shown in table 1 below:
Table 1
| The DTMF sign indicating number | 2 | 3 | 2 | 4 | 2 | 5 | 1 | 1 | * | 9 | 9 | # |
| Time point (ms) | 0 | 200 | 500 | 600 | 900 | 1000 | 1300 | 1600 | 1900 | 2200 | 2300 | 2400 |
If preestablish:
Receive that the DTMF sign indicating number of two continuous standard key, 2,3 correspondences represents input alphabet " A ";

After having determined the character that each button can be imported, owing to need import a plurality of kinds of characters by a standard key, send the number of times of the DTMF sign indicating number of corresponding standard key when also needing to determine each character of input, for this reason, to being assigned each standard key of character, generate one by this standard key can import distribute the list entries of character; When importing each character, the number of times that telephone terminal repeats to send the DTMF sign indicating number of corresponding standard key equals the position number of this character in corresponding list entries, perhaps repeats to send number of times and is the integral multiple of the character quantity that corresponding standard key can import and add the position number of this character in corresponding list entries.
Referring to Fig. 1, digital 0-9 is corresponding one by one with standard key 0-9 respectively, is assigned the standard key 2-9 of English alphabet, generates one respectively and can import the list entries of corresponding numeral and letter by this standard key, that is:
The character string that standard key " 2 " can be imported is " 2ABC ";
During input digit 2, it arranges first in sequence, the DTMF sign indicating number of telephone terminal transmission standard key 2 correspondences 1 time, and the times N that perhaps sends this DTMF sign indicating number satisfies N=(4*n+1), and wherein, n is a positive integer;
During input alphabet A, it arranges second in sequence, the DTMF sign indicating number of telephone terminal transmission standard key 2 correspondences 2 times, and the times N that perhaps sends this DTMF sign indicating number satisfies N=(4*n+2), and wherein, n is a positive integer; And be no more than predefined interval duration threshold value the blanking time that sends this same DTMF sign indicating number;
During input alphabet B, it arranges the 3rd in sequence, the DTMF sign indicating number of telephone terminal transmission standard key 2 correspondences 3 times, and the times N that perhaps sends this DTMF sign indicating number satisfies N=(4*n+3), and wherein, n is a positive integer; And be no more than predefined interval duration threshold value the blanking time that sends this same DTMF sign indicating number;
During input alphabet C, it arranges the 4th in sequence, the DTMF sign indicating number of telephone terminal transmission standard key 2 correspondences 4 times, and the times N that perhaps sends this DTMF sign indicating number satisfies N=(4*n+4), and wherein, n is a positive integer; And be no more than predefined interval duration threshold value the blanking time that sends this same DTMF sign indicating number.
In like manner, the character that can import of standard key " 3 " is " 3DEF ";
The character that standard key " 4 " can be imported is " 4GHI ";
The character that standard key " 5 " can be imported is " 5JKL ";
The character that standard key " 6 " can be imported is " 6MNO ";
The character that standard key " 7 " can be imported is " 7PQRS ";
The character that standard key " 8 " can be imported is " 8TUV ";
The character that standard key " 9 " can be imported is " 9WXYZ ".
With user's operation standard button " 2 " is example, if it is inferior to press N (N 〉=1) continuously, and when being no more than the interval duration threshold value of setting blanking time, then following logic is followed in the expression input at every turn, and promptly the network side equipment that collects the digits goes out the character of current reception according to following logic determines:
M=N%4; Formula (1)
Formula (1) expression M is N divided by 4 remainder, wherein N is number (the every operation one-touch of user " 2 " of receiving the identical DTMF sign indicating number that is no more than default interval duration threshold value blanking time continuously that counts, telephone terminal sends a DTMF sign indicating number corresponding with standard key " 2 " to network side, therefore, network side receives that the number of identical DTMF sign indicating number is identical with the number of times that the user presses corresponding standard key).
If M equals 1, then represent the current numeral 2 that is input as;
If M equals 2, then represent the current alphabetical A that is input as;
If M equals 3, then represent the current letter b that is input as;
If M equals 0, then represent the current letter C that is input as.
In like manner, when user's operation standard button " 9 ",, and be no more than predefined interval duration threshold value each blanking time if it is inferior to press N (N 〉=1) continuously, then following logic is followed in expression input, and promptly the network side equipment that collects the digits goes out the character of current reception according to following logic determines:
M=N%5; Formula (2)
If M equals 1, then represent the current numeral 9 that is input as;
If M equals 2, then represent current input alphabet W;
If M equals 3, then represent current input alphabet X;
If M equals 4, then represent current input alphabet Y;
If M equals 0, then represent current input alphabet Z.
The rest may be inferred for other buttons.
In the keyboard layout shown in Figure 1, operation is assigned to different alphabetical correspondences on the different standard key for the convenience of the user, because different standard key has its corresponding DTMF sign indicating number, like this, network side can also carry out the division of dual-tone multifrequency code character according to the different DTMF sign indicating numbers that receive; Again according to the number that is no more than the identical DTMF sign indicating number of predefined interval duration threshold value blanking time that receives continuously, unique character of determining concrete reception.
Suppose that pre-set interval duration threshold value (the duration threshold value can be configured as required at interval) is 300 milliseconds (ms).That is: network side is received when be no more than 300 milliseconds the blanking time of identical DTMF sign indicating number, represents the signaling of same character, and the adjacent DTMF sign indicating number that receives when order is divided in the same dual-tone multifrequency code character; When only the interval duration between inequality or two identical DTMF surpasses 300 milliseconds when former and later two DTMF sign indicating numbers, the corresponding adjacent DTMF sign indicating number that receives is divided in the different dual tone multiple frequency code characters, is expressed as and receives different characters.
The device start DTMF that collects the digits that supposes network side collects the digits, and finishes to collect the digits to receive that " # " key table shows, establishing the time point of receiving first DTMF sign indicating number is 0, and its result that collects the digits is as shown in table 2 below:
Table 2
| The DTMF sign indicating number | 2 | 2 | 2 | 2 | 2 | 2 | 1 | 1 | * | 9 | 9 | # |
| Time point (ms) | 0 | 200 | 400 | 600 | 800 | 1000 | 1200 | 1400 | 1600 | 1800 | 2200 | 2400 |
Then be according to the above-mentioned decision logic analysis that collects the digits:
Initially receive 6 DTMF sign indicating numbers corresponding continuously, and be 200 milliseconds blanking time that less than 300 milliseconds of the interval duration threshold values of setting, therefore, the character of judging reception is " A " with standard key " 2 ";
The 7th and the 8th DTMF sign indicating number are the DTMF sign indicating number corresponding with standard key " 1 ", although the interval between two DTMF sign indicating numbers only is 200 milliseconds, but owing to do not define any other character on the standard key " 1 ", therefore, the character of judging reception is continuous two " 1 ";
The 9th DTMF sign indicating number is and the corresponding DTMF sign indicating number of standard key " * " key that therefore, the character of judging reception is " * ";
The 10th and the 11st DTMF sign indicating number are the DTMF sign indicating number corresponding with standard key " 9 ", but because be 400 milliseconds the blanking time between two DTMF sign indicating numbers, greater than 300 milliseconds of the interval duration threshold values of setting, the character of therefore judging reception is continuous two " 9 ";
The 12nd DTMF sign indicating number is the DTMF sign indicating number corresponding with standard key " # ", and therefore, the character of judging reception is " # ";
Receive that character " # " represents this end that collects the digits, therefore, last table 1 collects the digits the result for receiving character string: " A11*99# ".
As can be seen from Figure 1, have only standard key and capitalization English letter in the keyboard layout.In order to realize the input of small letter English alphabet, can send one group of DTMF sign indicating number of arranging to network side by communication terminal, carried out the font switching with the character of indicating follow-up input; When the character of input is letter, indicate it to carry out the capital and small letter switching.
For example: function key of interpolation on standard key (
) represent to carry out the switching (the acquiescence initial condition is capitalization) between the English upper and lower case letter.Suppose with the switching between the DTMF representation upper and lower case letter of continuous even number time transmission standard key " * " key correspondence.As shown in Figure 2, with the handoff functionality key (
) be arranged on the standard key " * ".
Suppose that the network side current DTMF sign indicating number of receiving of equipment that collects the digits is as shown in table 3 below:
Table 3
| The DTMF sign indicating number | 7 | 7 | 7 | 7 | * | * | 8 | 8 | 8 | * | 9 | 9 | # |
| Time point (ms) | 0 | 200 | 400 | 600 | 800 | 1000 | 1200 | 1400 | 1800 | 2000 | 2200 | 2400 | 2600 |
Then collect the digits the decision logic analysis as can be known according to above-mentioned, for the second time the character result that collects the digits is: " Rt8*w# ".
Like this, adopt keyboard layout shown in Figure 2, the character set that collects the digits of network side is: the numeral of 0-9, *, #, capitalization English letter (A-Z), small letter English alphabet (a-z), and English capital and small letter switching controls symbol
Above-mentioned situation two is with the difference of situation one: because only corresponding a kind of TDMF sign indicating number of character in the situation two, therefore, if two adjacent TDMF sign indicating number differences, then can also carry out the division of dual-tone multifrequency code character, and need not to judge that whether these two time of receptions between the adjacent TDMF sign indicating number are at interval more than or equal to default interval duration threshold value according to these two adjacent TDMF sign indicating numbers.This shows, situation one is a kind of generic case, only need to set the corresponding relation of dual-tone multifrequency code character and character,, can parse the corresponding character of input according to the dual-tone multifrequency code character of determining by judging that the interval duration that receives between the adjacent TDMF sign indicating number carries out the dual-tone multifrequency code character and divides.And situation two is actually a kind of concrete application scenarios, pre-defined on the standard key of communication terminal by the character that will need to import, network side is according to the different TDMF sign indicating numbers that receive and receive the division of carrying out the dual-tone multifrequency code character with a kind of number of TDMF sign indicating number continuously, thereby realizes parsing the corresponding character of input.
Of particular note, above-mentioned keyboard layout is only for for example, in the practical application, different characters (behind English alphabet, can also establish other symbol of special requirement etc. in addition) can be defined into arbitrarily on the standard key.Adopt above-mentioned same principle,, can realize the input of kinds of characters by the equipment that collects the digits of communication terminal and the network side resolution rules of making an appointment.
