Description
Technical field
The present invention relates to the integrated CTI of a kind of computer and phone (Computer TelephonyIntegration) technology; Relate in particular to a kind of at terminal equipment (TE; Terminal Equipment) and set up the method and the device thereof of transmission of messages between portable terminal (MT, Mobile Terminal).
Background technology
In the disclosed content of presents, like no specified otherwise, then TE, MT equipment refer to have terminal equipment, the portable terminal of phonetic function respectively.AT order is by the invention of Hayes company and be the employed Modem commands language of all modem manufacturers.Every order is with letter " AT " beginning, heel letter and number.
Along with computer and development of Communication Technique; The integrated CTI of computer technology and telephony (Computer Telephony Integration) must be used widely; And along with the progress of mobile technology; With original mode of only transmitting information through wireless network, become the next relevant information of present wireless network transmission and be transferred to TE equipment in real time, pellucidly through the MT terminal, perhaps the relevant information of TE is delivered to the MT terminal in real time; Carry out the secondary transmission by the characteristic of MT terminal access of radio network then, the change of this information transmission mode must have huge application space.The present invention is exactly the interface characteristic through research TE, MT, realizes a kind of scheme that voice messaging transmits of between TE and MT, carrying out through the mode of introducing control channel and message channel.
Along with the maturation of embedded technology, the physical interface between TE and MT is also varied, and using now has interfaces such as USB, PCMCIA, EXPRESS more widely.On these interfaces, can support equipment complex greatly, promptly can on a physical interface, support experimental process equipment.Such as, the wireless modem network interface card of a USB interface may be mapped to the equipment complex of a modem subset and several serial ports subsets in computer.TE and MT may utilize these several subsets to communicate simultaneously so, and further, TE may utilize these several subsets to carry out communicating by letter of AT order with MT simultaneously.The example of a reality is that computer utilizes AT to order the connection of surfing the Net on the modem mouth, the operation that on a serial ports, utilizes the AT order to read signal strength signal intensity simultaneously.
For the control mode between TE and MT, traditional AT order is widely used between various TE and the MT, all is usually to initiate an AT order by TE to MT, and MT returns the response to this AT order with command analysis, after carrying out.With the wireless data card is example, and wireless data card can be regarded as the entity that combines MT and terminal adapter (TA, Terminal Adapter) function, and computer can be regarded TE as.When information processing is carried out in common AT order, the employing asynchronous process mode that generally adopt the Synchronous Processing mode, also has.Based on the serial ports working method, an AT process of commands process promptly is a conversation procedure, and is as shown in Figure 1.
Development along with mobile communication technology; Information interaction content between MT and the TE is more and more; For example, the single terminal equipment of only handling at the enterprising lang message breath of MT can not satisfy client's demand, makes information maximization be delivered to TE equipment and perhaps TE information is passed to MT; Finally send and become a kind of demand by the characteristic realization information of MT access of radio network; But the AT serial ports work according to conventional just can not finely meet the demands because the real-time of conventional AT command process mode a little less than, common only have the information Control function and can not satisfy the ability of between MT and TE, setting up a two-way voice channel.
Comprise two types of schemes relevant in the prior art with the present invention.One type of scheme is a transmitting data information between MT and TE, but AT orders and data message all transmits on same passage, so real-time is not strong, and carries out transfer of data through setting up the IP connection between MT and the TE, and therefore the process of a dial-up connection will be arranged.The another kind of TE of being passes through the scheme of wireless speech module or TA realization voice call; Voice signal inputs or outputs from wireless speech module or terminal adapter TA; Rather than in TE enterprising lang sound information processing with input or output; TE only is used for sending AT order control wireless speech module or terminal adapter TA, so free of data message transmission between TE and wireless speech module or the terminal adapter TA.
Summary of the invention

Wherein, processing module 24 comprises the first processor 241 and second processor 242.First processor 241 is used for producing control messages and sending the order generation module to according to user instruction, and MT makes a call such as order; Second processor 242 is used for deal with data message, if data-message is a speech message, then second processor provides the encoding and decoding function of voice signal.
Need to prove that the function that the first processor 241 and second processor 242 are carried out also can realize in same processor.
For technical scheme of the present invention is more readily understood, be that AT order, data-message are that embodiment 1 under the speech message situation describes to control command now.
Here, the AT order is the AT order of control MT, or by the defined AT order of international telecommunication organizational standard department (ITU-T) recommended standard.In addition, this AT order also can be the compatible AT order of being expanded definition by these two kinds of standards.
Introducing two special serial ports passage, control channel and message channels respectively on the MT He on the TE.Control channel is used for carrying out the transmission of control information, as initiating the AT signaling of audio call or terminated speech service.Message channel is the double-directional speech channel, is used for carrying out speech message and transmits in real time.
Fig. 3 shows the embodiment of the invention 1 said main flow process of between TE and MT, setting up the method for transmission of messages.
Step 34; According to the information on the message channel; On the message channel of opening, transmit speech data code stream last the carrying out of MT, TE after coding and decoding handles respectively, the speech data code stream that this speech data code stream and MT transmit when directly carrying out voice call through wireless network is similar.
Figure 4 and 5 show the embodiment of the invention 1 described method detailed process under caller and called situation respectively.
Do under the called situation at TE, carry out the transmitting-receiving of AT order between TE and the MT so that MT transmission speech message is as shown in Figure 4 to the idiographic flow of TE.
Step 401 is carried out message and is shaken hands, up to shaking hands successfully between TE and MT.
Step 402, TE waits for relevant control information, when the MT that shakes hands with TE is called out, receives that promptly MT sends to TE with this information through control channel through sending corresponding AT order when calling out from the other user on the wireless network.
Step 403, TE needs MT to send the speech message of automatic network side.The control information that TE sends according to MT is sent response message and notification message passage and is prepared to receive speech message.
Step 404, MT receives that the speech message that will pass through coding after the control response information of TE passes to TE through message channel, TE receives speech message through message channel.This speech message through coding is a speech data code stream, and the speech data code stream that speech data code stream and MT transmit when directly carrying out voice call through wireless network is similar.
Step 405 after the speech message that TE receives message channel carries out analyzing and processing, is given own corresponding COBBAIF module and is handled.
Do under the caller situation at TE, carry out AT order transmitting-receiving between TE and the MT so that TE transmission speech message is as shown in Figure 5 to the idiographic flow of MT.
Step 501 is carried out message and is shaken hands, up to shaking hands successfully between TE and MT.
