Based on above-mentioned mobile terminal hardware configuration and communication system, each embodiment of the inventive method is proposed.
Fig. 3 is a kind of flow chart of the method realizing voice call of the present invention, as shown in figure 3, in first terminal and second
During conversing between terminal, comprising:
Step 300: the region that first terminal real time scan pre-sets represents, to obtain, the pixel letter treating interactive information
Breath.
By the region pre-setting, user can be on touch screen by the way of finger touch or the mode of pointer exists
The drafting carrying out pattern in this region pre-setting treats interactive information to present.
In this step, in the communication process with second terminal for the first terminal, needs transmission treats the terminal of interactive information such as
First terminal can be scanned to the region that itself pre-sets in real time, and obtains the picture that interactive information is treated in the expression that obtains of scanning
Vegetarian refreshments information.Wherein, pixel information can be represented by binary data.
In this step, by the method for traversal, pixel information from first to last can be scanned to generate binary data；
The schematic diagram of the pixel information in the as shown in Figure 4 region pre-setting, obtains after being converted into binary data:
Or it is contemplated that the real-time demand refreshing, and valid pixel " 1 " under normal circumstances can be fewer than " 0 ", in order to the greatest extent may be used
The raising efficiency of transmission of energy, reduces transmitted data amount, present invention also offers a kind of method of row scanning.The method tool of row scanning
Body includes:
The row data changing is generated according to pixel information, according to the transformat pre-setting, the row that will generate
Data is packaged into binary data.
With the schematic diagram of the row scanning embodiment shown in Fig. 6, according to the transformat pre-setting, set up a set of right angle and sit
Mark system, with such as first, lower left corner pixel as initial point, according to the pattern in schematic diagram, the data of required transmission is two (2
OK):
15th row: 0110000000000000
16th row: 0110000000000000
In order to improve efficiency, do not consider error code and verification, directly use the mode of transparent transmission, pre-set a kind of communication lattice
Formula, illustrates and includes following information:
Start bit is hexadecimal number 0xaa, line number, and line number full stop is hexadecimal number 0xcc, and dot array data terminates
Position is hexadecimal number 0xff.
Taking transmit the 15th row information as a example, its binary element is as follows:
10101010 (start bit) 00010000 (line number) 11001100 (line number full stop) 0110000000000000 (point
Battle array data) 11111111 (stop bits).
Step 301: the pixel information obtaining is encoded to be modulated into tone code.
Tone code in this step can be high-frequency audio signal.
It is preferred that in order to avoid voice call is impacted as far as possible, the frequency of more than 3.5khz can be selected to enter to two
The pixel information that data processed represents is modulated, and 3.5khz such as can be selected to represent Binary Zero, 3.8khz represents binary system
1.It is illustrated in figure 5 first terminal modulation waveform schematic diagram.It should be noted that being only that citing is described, specifically here
Value can determine according to practical situation, the protection domain being not intended to limit the present invention.
For binary data, it is possible to use the mode of Binary Frequency Shift Keying (2fsk) is modulated, and will send
Binary data be converted into the audio signal of above two frequency.
In the present invention, by way of using Binary Frequency Shift Keying, the usual speech channel of 4k frequency range is passed through to the greatest extent
Measure high frequency and carry out tone code transmission, it is to avoid fall in people's audio spectrum, alleviate the interference to voice call.
Step 302: the tone code obtaining is sent to by second terminal by talk channel.
Tone code after modulation sends (tx) direction by voice channel and is sent to second terminal.
Taking high-pass platform as a example, can be by existing in call music delivery module, in call to sending out
Tx direction is sent to be mixed into the audio signal of modulation.
In the present invention, by the method for traversal, tone code from first to last can be transmitted to second terminal；Or swept using row

Figure 10 realizes the flow chart of the embodiment of method of voice call for the present invention it is assumed that terminal a is logical with the process of terminal b
In words, terminal a sends interactive information to terminal b, as shown in Figure 10, comprising:
Step 1000: terminal a draws a design in the region pre-setting.
In this step, by the region pre-setting, user can be on touch screen by the way of finger touch or touch-control
The drafting that the mode of pen carries out pattern in the region that this pre-sets treats interactive information to present.
Step 1001: the line number that the scanning of terminal a changes.
Assume do not have the corresponding binary number of row changing to be 0, then as long as the row having binary number 1 is considered as changing
The row becoming.
Step 1002～step 1003: terminal a generates row data；The row data of generation is beaten by terminal a according to protocol format
It is bundled into binary data.
After the row data using the method for row scanning, the corresponding pixel information that draws a design being generated in the present embodiment, press
It is packaged as binary data according to the transformat pre-setting.Implement and may refer to, shown in Fig. 6, repeat no more here.
Step 1004: terminal a is modulated to binary data generating tone code, and tone code is mixed into voice channel transmission tx
Direction is transmitted.
For binary data, it is possible to use the mode of Binary Frequency Shift Keying (2fsk) is modulated, and will send
Binary data be converted into the audio signal of above two frequency.
Tone code in this step can be high-frequency audio signal.
It is preferred that in order to avoid voice call is impacted as far as possible, the frequency of more than 3.5khz can be selected to enter to two
The pixel information that data processed represents is modulated, and 3.5khz such as can be selected to represent Binary Zero, 3.8khz represents binary system
