Embodiment
At present communication terminal (such as, mobile phone, landline telephone, individual palmtop PC, the soft phone of PC etc.) between the method for transmitting data information mainly comprise note, multimedia message and color E etc., the method of these transmitting data informations need take special-purpose short message channel and data channel and data information transmission is all adopted store-and-forward mechanism, such as, adopt note transmitting data information between communication terminal to transmit by the storage of short message server.There is the relative delay when adopting these method transmitting data informations of prior art, can't guarantees the real-time of data communication.Given this, define the mapping relations of setting up between key information and data message one to one at key information and data message intercropping respective coding, in the voice call process, in the voice channel of setting up, transmit described key information by dtmf signal, the recipient can obtain data message according to the described key information of the decoding processing of mapping relations one to one between key information and data message after receiving key information, has realized conversation time purpose of transmitting data information between communication terminal in real time.
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
Fig. 1 is that an example structure of terminal equipment of the present invention is formed schematic diagram.As shown in the figure, the terminal equipment of present embodiment comprises push-button unit 10, DTMF codec unit 20, transmitting element 30, receiving element 40, data decode unit 50 and processing output unit 60, wherein,
Described push-button unit 10 is used to obtain key information, and in the specific implementation, push-button unit 10 can also can be the touch-screen virtual key for physical button, obtains key information by the button or the keystroke sequence combination that receive user's input.The embodiment of the invention is by defining the mapping relations of setting up between key information and data message one to one at key information and data message intercropping respective coding, when the user imports respective keys information, described key information represented promptly that the user need transmit with described key information data message one to one, such as, suppose 123 keystroke sequence group representative " I am hard hit ", when the user clicks the combination of 123 keystroke sequence, then representative of consumer needs the data message of transmission " I am hard hit ".
Described DTMF codec unit 20 is used for when sending data message, and the described key information that described push-button unit 10 is obtained carries out the dtmf code processing, generates the dtmf code data; When receiving the dtmf code data, the described dtmf code that receives is carried out decoding processing, obtain key information.Dtmf signal is made of the audio signal stack of two frequencies.The frequency of these two audio signals is from two groups of preallocated group of frequencies: line frequency group or row are group frequently.Each is to numeral or symbol on button of the unique expression of such audio signal.Such as, suppose to have on the phone 16 buttons, 10 numerical keys 0～9 and 6 function key *, #, A, B, C, D are wherein arranged.According to according to combinatorial principle, 16 buttons should have 8 kinds of different single audio signals to match in twos.So claim that dtmf signal is a multifrequency, make up for 2 kinds because of DTMF employing any extraction from 8 kinds of frequencies again and carry out encoding process, so be called the encoding process technology of " getting 2 in 8 " again.According to the suggestion of CCITT, the multiple frequency of Cai Yonging is 687Hz, 770Hz, 852Hz, 941Hz, 1209Hz, 1336Hz, 1477Hz and 1633Hz etc. in the world.Multiple different combination be can form with these frequencies, thereby multiple different numeral or function key represented.
Described transmitting element 30 is used for the dtmf code data that described DTMF codec unit 20 carries out generating after dtmf code is handled are sent.Dtmf code can directly transmit in the voice channel that conversation is set up, therefore transmitting element 30 can just described DTMF codec unit 20 carries out dtmf code and handles the dtmf code data that the back generates and send in the voice channel of connection, adopts the voice channel transmitting data information to realize the purpose of real-time transmission data information in the communication process on the one hand; On the other hand, make data information transmission not need other paying, saved user cost.
Described receiving element 40, be used to receive dtmf code, after receiving dtmf code, described coding sent to DTMF codec unit 20 and carry out decoding processing.
Described data decode unit 50 is used for carrying out decoding processing according to the key information that the mapping relations between key information and data message obtain after to described DTMF codec unit 50 decoding processing, obtains data message.
Described processing output unit 60 is used for that the data message that obtains after described data decode unit 50 decoding processing is carried out output mode and handles back output.Handle output unit 60 and can will obtain data message with back outputs such as Document type data, speech datas according to recipient's individual character design.Such as, when the recipient receives the data message of " I am hard hit ", can be to play back behind the speech data with described processing data information by handling output unit 60, also can be to show behind the sad picture described processing data information.
