detailed description

In the embodiment of the present invention, after the first terminal establishes a call with the second terminal, the phone number to be transmitted is encoded into a dual-tone multi-frequency (DTMF) signal and sent to the second terminal; the second terminal The received DTMF signal is parsed into a phone number and the phone number is saved.

The invention will be further described in detail below with reference to the drawings and specific embodiments.

The embodiment of the invention implements a method for sending a phone number during a call of a terminal. As shown in FIG. 1 , the method mainly includes the following steps:

Step 101: After the first terminal establishes a call with the second terminal, the phone number to be delivered is encoded into a DTMF signal.

Here, the first terminal and the second terminal are only used to distinguish different terminals, and are not used for limitation; wherein, the first terminal refers to a phone number capable of converting a phone number into a DTMF signal and converting the signal into a DTMF signal. The terminal transmitted to the second terminal; the second terminal refers to a terminal capable of receiving a telephone number converted into a DTMF signal and capable of parsing the DTMF signal.

In this step, when the first terminal confirms that the contact phone number needs to be sent to the second terminal during the call with the second terminal, the first terminal can directly open the address book or the call in the first terminal. Recording, selecting the corresponding contact phone number, selecting the corresponding DTMF transmission option, at this time, the user's selection will trigger the first terminal to encode the phone number selected by the user into a DTMF signal and send it to the second terminal; or The first end user can also Manually inputting the phone number directly on the first terminal. At this time, the user's input operation will trigger the first terminal to encode the phone number input by the user into a DTMF signal and send it to the second terminal; in this process, due to the first terminal The opposite end of the call (that is, the second terminal) is determined. Therefore, the telephone number encoded as the DTMF signal is only sent to the second terminal; and, compared with the existing method for transmitting the telephone number by means of a short message or the like. In this way, the method provided by the embodiment of the present invention does not need to pay an additional fee, and is simple and convenient, and does not need to terminate the call.

The DTMF signal is essentially a combination of two simultaneously transmitted signal frequencies. Table 1 is a digital representation of the DTMF frequency superposition.

Table 1

As can be seen from Table 1, each number, letter or symbol is uniquely determined by a high frequency signal and a low frequency signal. Therefore, when the telephone number is transmitted to the second terminal by the DTMF method, the error rate of the telephone number is very low.

Encoding the telephone number as a DTMF signal includes: encoding a telephone number selected by the first terminal user through an address book or a call log, or a telephone number manually input through a dialing key, encoded in a digital sequence as a DTMF signal; each of the telephone numbers Digitally encoded as a combination of corresponding low frequency and high frequency signals;

Wherein the encoding the phone number into the DTMF signal comprises:

The number 1 is encoded as a combination of low frequency 697 Hz and high frequency 1209 Hz; number 2 is encoded as a combination of low frequency 697 Hz and high frequency 1336 Hz; digital 3 is encoded as a combination of low frequency 697 Hz and high frequency 1477 Hz; number 4 is encoded as low frequency 770 Hz and Combination of high frequency 1209Hz; encoding number 5 It is a combination of low frequency 770Hz and high frequency 1336Hz; encodes digital 6 as a combination of low frequency 770Hz and high frequency 1477Hz; encodes digital 7 as a combination of low frequency 852Hz and high frequency 1209Hz; encodes digital 8 as low frequency 852Hz and high frequency 1336Hz Combination; encodes the number 9 as a combination of low frequency 852 Hz and high frequency 1477 Hz; encodes the number 0 as a combination of low frequency 941 Hz and high frequency 1336 Hz.

For example, when the first terminal user wishes to send a telephone number of 12345678, the user selects through the address book or the call record. After the phone number to be sent, the first terminal automatically encodes the phone number as the DTMF signal corresponding to "*12345678#"; or, when the user manually inputs the phone number through the dial button, the * key is required as the start of the number. After entering the number, use the # key to end; if you enter the error manually, you can immediately press the # key to end, and start again with the * key, and end with the # key to enter the phone number again; thus for the second terminal In other words, it is only necessary to identify the number between the * and # numbers as a telephone number for display to the second end user.

In this scenario, the encoding the phone number as a DTMF signal includes:

The number 1 is encoded as a combination of low frequency 697 Hz and high frequency 1209 Hz; number 2 is encoded as a combination of low frequency 697 Hz and high frequency 1336 Hz; digital 3 is encoded as a combination of low frequency 697 Hz and high frequency 1477 Hz; number 4 is encoded as low frequency 770 Hz and Combination of high frequency 1209 Hz; encoding number 5 as a combination of low frequency 770 Hz and high frequency 1336 Hz; encoding number 6 as a combination of low frequency 770 Hz and high frequency 1477 Hz; encoding number 7 as a combination of low frequency 852 Hz and high frequency 1209 Hz; 8 is a combination of low frequency 852 Hz and high frequency 1336 Hz; encodes digital 9 as a combination of low frequency 852 Hz and high frequency 1477 Hz; encodes digital 0 as a combination of low frequency 941 Hz and high frequency 1336 Hz;
