Description

The method and apparatus of the Internet indirect addressing direct communication

Technical field

The present invention relates at multiplex communication system particularly in the internet, carry out addressing by non-ip address, realize simulation, digital information or photo-telegraphic direct transmission then, particularly carry out addressing and set up the direct transmission that the Internet passage is realized by the PSTN net.

Background technology

Developing into internet internet from public phone network (PSTN net) is the Internet of representative, and human application to digital communication technology more and more widely; The someone proposes digital communication means again, particularly along with the extensive use of Email, is that phone or other analog input of input was once out in the cold with people's sound.Because the PSTN net based on analogue transmission is expensive communication mode, and the available relative low price of Email is finished transmission of Information.But the most important feature of Email is the transmission to terminal of it and non real-time terminal, but through server forwards, this also is its weakness.In addition, the original input of Email has many restrictions, and for example seal and signature need connect the scanner input in addition; Non-mainstream literal needs special-purpose software to import or the like.Therefore, convenient or the like from the input of original document, the pluses and minuses of this traditional communication mode such as facsimile machine and Email can be described below:

Fax was invented in 19th century; Just begin to enter commercial use up to the seventies in 20th century, facsimile machine develops into today number in ten million platform from 50,000 in 1970.

Fax is to use special equipment, end in communication channel reads document image, and under other end copy, the modal ordinary audio telephone wire that is to use is undertaken by the PSTN mode, the equipment that is specifically designed to fax is facsimile machine, can use a computer in addition by (computer), it uses Modem (modulator-demodulator) to carry out, and need install software on computers, present most computer all is equipped with Modem, mode with software and Modem combination can receive, send fax, based on PC fax is the inexpensive manner of transmission hard copy, fax is quickly and easily to give the group that deals with problems with file transfer to the contribution of dealing with problems, and no matter the geographical position how, its especially is fit to needs and affixes one's seal, the file that the signature authentic work is confirmed.

When the Internet appearance, the expense that online computing uses the E-Mail mode to send mail is the most cheap, so the E-Mail mode is in fashion the whole world, general computer user is to carry out the online of (PSTN) dial mode with Modem.Sending the E-Mail mail needs to transmit in the middle of the webmail service device, so stall for time and to receive in real time and receive just to transmit because of the centre, transmit leg does not know when the recipient receives, the E-Mail mode has mess code to occur in addition, the mail that receives can't be discerned at all, and it is more to be that the chance of mess code appears in the languages of non-English Department especially.

Mode with the scanning fax can solve mess code.Such as with after the scanner scanning, send mail with the E-Mail mode again, but this mode can only scan portion at every turn, can not multipage, efficient is low.If to computer, because facsimile machine is operated in the PSTN mode, existing Modem interface can not directly scan computer with scanning of facsimile equipment, want two telephone wires just can carry out, start fax software by stored-program control exchange, receive fax after, restart E-Mail software, could send, efficient is very low.

Sending fax with facsimile machine at Internet, to have a kind of be the mode that adopts gateway system, and it is based on call center service carries out, and the user need hand over service fee, is not inexpensive manner.

Can fax be replaced by E-Mail based on the variety of problems of above-mentioned existing system? should not can! Fax also can develop; Fax has reason to exist: the legal status of (1) fax is than Email height; (2) not every file is all in computer; (3) fax is exactly a copy from definition; (4) fax of Jie Shouing is a necessary being; (5) not every languages can both send Email; (6) facsimile machine is simple to operate; Whole world number also is being used in facsimile machine necessarily; (7) manufacturer still produces renewal, more advanced facsimile machine.

Existing facsimile machine has following problem: (1) cost of use height; (2) lack of wisdom; Especially aspect fax through internet; (3) computerized combination degree is low; (4) safety, confidentiality are poor.

In fact, development has in recent years combined some advantage of PSTN net and the Internet, has proposed intercity line partly through internet transmission and the user inserts the method for part through PSTN in some solution.With the fax is example, existing systems and about more than 60 of relevant fax through internet softwares, and wherein relatively more outstanding having is following:

(1) star of free fax: be a free fax software, can send international fax by the Internet, the form of employing printer sends fax, and it does not have special-purpose hardware unit, shortcoming: can not directly receive with the transmission of scanning of facsimile equipment file; Be common software.

Because the internal processes P that has designed telephone for special use switch 3 and wherein moved _I, made that at two same devices carrying out the Internet indirect addressing direct communication between the terminal of this telephone for special use switch 3 becomes extremely simple and convenient.The simple description of this device be can be described as Local Exchange has been moved back to house, be contained in the lane terminal of oneself; But also in the computer of local terminal, gateway has been installed, only need use the passage of the Internet and need not to carry out direct communication through other intermediate link.

In the practical operation, described indirect addressing is exactly that the telephone set with oneself, other PSTN terminals such as data processing equipment that facsimile machine maybe can be dialed the number are carried out the dialing operation.Certainly the terminal of oneself has been equipped with telephone for special use switch 3; And the other side's terminal also must be identical terminal.With the facsimile machine that has only an outside line is example, during off-hook, facsimile machine is connected telephone for special use switch 3 through communication line control circuit 38, and phone call/facsimile machine off-hook detection circuit 312 detects off-hook, and exchange is handled CPU32 notification signal sound generation circuit 352 and provided dialing tone.After the dialing, this machine particular telephone instrument 3 detects whether contain internal agreement, if any, then replace the public exchange response to call out, send ring back tone by ringing-current generation circuit 351 and send Modem11; The dtmf signal of dialing is converted into fsk signal, after the inner ring one, promptly by terminal described fsk signal is translated into callee PSTN address code and stores.On the one hand, this machine telephone for special use switch 3 transmits the fax Acknowledgement Tone by simulation circuit for answering 33, tells " the other side " off-hook for facsimile machine 2; This facsimile machine 2 promptly begins to scan facsimile file, carries out " transmission ".This facsimile signal now is received through MODEM11 by this dynamo-electric brain 12, and for facsimile machine, as broad as long with the transmission of simulation state.And then, terminal is called out the callee with the PSTN address code of this storage, and the automatic online of calling party simultaneously obtains dynamic IP addressing, in the central server login, accepts registration ID sign indicating number authentication; Computer is set up dynamic gateway, uploads this machine PSTN address to server.The ring detecting circuit 313 of callee's telephone for special use switch 3 measures call signal through exchange processing CPU32, communication line control circuit 38, promptly surf the Net by outside line through communication line control circuit 38 by modulator-demodulator 11, obtain callee's dynamic IP addressing, with this IP address logon server, accept dedicated registration ID sign indicating number authentication; The callee sets up dynamic gateway simultaneously, uploads callee PSTN address.Central server will be passed to the calling party under the callee IP address; The calling party is used callee IP address to send and is created the connection request agreement.As this moment the calling party still work, promptly can respond calling, to the agreement of calling party's loopback oneself, both sides get in touch with success, set up the direct access communication channel on the Internet.The calling party accessed the fax paper of having stored and transmitted from computer 12 this moment.This direct internet facsimile has only the SLC subscriber line charge of expenses of surfing Internet and both sides location Access Network, and is without any intermediate link, very cheap naturally, reasonable and reliable.For guaranteeing once to communicate by letter successfully, can also can not respond the callee, thereby can not set up direct access communication channel the time, described fax paper be changed the mailbox that is sent to the callee by the E-mail mode, calling party's communication task is once finished.Certainly E-mail has been not direct communication.

Said process changes telephone set into, and the calling party can be after moving flat the telephone number of knowing in Changshu, and device moment of both sides is set up speech channel after finishing online connection, as the callee people is arranged also, and this toll telephone has been exactly cheapest phone.

In a further embodiment, described calling party has two outside lines to be connected with the callee.After caller calls callee and online obtain dynamic IP addressing, do not having under the situation of server, the callee can be behind certain number of times ringing tone off-hook, during callee's off-hook, at first send internal agreement, data; The calling party receives callee's internal agreement data, triggers FSK telecommunication program, and transmits calling party's dynamic IP addressing, PSTN address and the signal of inviting the callee to surf the Net to the callee.At this moment, if the callee, then can transmit callee's oneself IP address and the agreement of agreeing to be connected by another outside line on the net by the outer alignment calling party who has surfed the Net.The calling party promptly can send establishment connection request agreement with callee IP address after receiving called IP address.The outside line of a free time is arranged if the callee does not surf the Net, will receive and store caller IP address and PSTN address, send the not state information of online to the calling party simultaneously.Then immediately by this idle outside line online.Callee after the online sends the agreement connection protocol with the caller IP address of storage to the calling party, and the calling party responds the back both sides and promptly sets up directly online communication port.

From the above description as seen, installing the telephone for special use switch, two terminal rooms of dynamic gateway have been set up, no matter an outside line is arranged still is two outside lines, can obtain dynamic IP addressing, set up dynamic gateway and wake callee's online up and obtain dynamic IP addressing through PSTN net in the short time at the utmost point, or exchange the IP address of two terminals, then set up online direct communication passage by central server or through another outside line, obtain the communication environment of low expense, finish direct communication.

Compared with serving as that the Internet that the basis is set up comes with the IP address, though the PSTN net is ancient, though because of the not high cost of use of extent for multiplexing high; But it has a cover vigor to be arranged very much and the simple address coding method, and that is exactly the telephone number that area code adds local number.This just telephone number of having continued to use last a century had both made the people feel warm, was simple and easy to memory again.Therefore, add the communication fee that the Internet is quite cheap, just constituted technical scheme of the present invention, make things convenient for everybody with the easiest addressing system of memory naturally.
