Terminal A sends unlatching blank by voice transfer channel and requests to give terminal B, and such as table 1, unlatching blank request is corresponded to
Operation code and parameter be respectively " * " and " 1 ", corresponding DTMF character number be 2, i.e., * 1, that is to say, that terminal A transmission
DTMF character string " * 1 " is to terminal B (205).
Terminal B sends operation ACK (response) to terminal A, such as table 1, the corresponding behaviour of operation ACK by voice transfer channel
Make code and parameter is respectively " # " and " 2 ", corresponding DTMF character number is 2, i.e. #2, that is to say, that terminal B sends DTMF word
Symbol string " #2 " to terminal A (206).
But since network is bad, terminal A is sending the behaviour for not receiving terminal B in 3 seconds after opening blank request and sending
Make ACK, then terminal A, which is retransmitted, opens blank request (207), and terminal B sends DTMF character by voice transfer channel thereafter
It goes here and there " #2 " to terminal A (208), and terminal A is smoothly received.At this point, terminal A opens blank (209), terminal B opens blank
(210)。

Parameter 2 is ordinate, numerical value 100, and the length of parameter 2 is 10bit, i.e., parameter 2 " 100 " is corresponding is represented in binary as
0001100100, parameter 3 is radius, numerical value 50, and the length of parameter 3 is 10bit, the i.e. corresponding binary form of parameter 3 " 50 "
It is shown as 0000110010, parameter 4 is angle, numerical value is that 360 i.e. circular angles are 360 °, and the length of parameter 4 is 10bit, i.e.,
Parameter 4 " 360 " is corresponding to be represented in binary as 0101101000.Therefore needing the binary code stream sent is 0,111 0001
1001 0,000 0,110 0,100 0,000 1,100 1,001 0,110 1000, the corresponding hexadecimal code stream of the binary code stream is total
The DTMF character string sequence that length is 11 are as follows: " 7190640c968 ".
Thereafter, the DTMF character string " 7190640c968 " encoded is successively sent to terminal B (215) by terminal A.Terminal B
After receiving DTMF character string, such as table 1, DTMF character string is converted into corresponding blank content, and update blank content, at this moment
One round (216) are shown on the blank of terminal B.Terminal B sends operation ACK expression to terminal A and is successfully updated, such as table 1, also
It is that terminal B gives terminal A transmission DTMF sequence: " #2 " (217).
The user of terminal B further updates blank (218), and terminal B is needed to send to terminal A and be obtained because not holding token
Token is taken to request, as table 1, that is, terminal B send DTMF sequence: " #0 " (219) to terminal A.Terminal A is obtained to terminal B transmission
Token response is taken, surrenders and holds token, if table 1, that is, terminal A send DTMF sequence: " #1 " (220) to terminal B, then eventually
End B holds token (221).
The blank content that user updates is encoded to DTMF sequence according to above-mentioned coding mode and is sent to terminal A by terminal B
(222), after terminal A receives the DTMF sequence that terminal B is sent, such as table 1, DTMF sequence is converted into corresponding blank content, and
It updates blank content (223).Terminal A sends operation ACK to terminal B, as table 1, that is, terminal A send DTMF sequence to terminal B
Column: " #2 " (224).
By above-mentioned process, the user of the user of terminal A and terminal B can on one side converse, while by way of writing it is real
Existing Written Communications.When the user of terminal A wants to terminate blank call, terminal A sends kill-call by voice transfer channel and asks
Ask (225) to terminal B, then terminal B sends kill-call response by voice transfer channel and gives terminal A (226), and terminal A is protected
It deposits blank content (227), terminal B saves blank content (228), ends here blank call.
