Description

ECONOMIC PROCESS FOR EFFECTING COMMUNICATION BETWEEN TWO COMMUNICATION
TERMINALS ACROSS THE INTERNET AND ASSOCIATED COMMUNICATION TERMINAL A computer network such as the Internet allows conversing parties equipped with a communication terminal to communicate with one another in real time.
To connect up to the Internet, a terminal must be furnished with access to the Internet provided by an access provider This may be telephone access, for example via the STN network (Switched Telephone Network) or else access via a local network LAN, such as a local company network, having its own Internet access provider Under all circumstances, the cost of a long distance communication is much more advantageous across the Internet than across an ordinary telephone network In the case of telephone access, one pays only for the cost of the telephone communication with the access provider, which generally takes place locally, and, in the case of access via a local network, the communication across the Internet is itself free of charge In short, the cost advantages of the Internet are extremely significant.
However, the Internet has certain drawbacks.
One of these drawbacks is related to the Internet's communication protocols The Internet is a packet-switching network which uses packet-based communication protocols such as the TCP (Transfer Control Protocol), UDP (User Datagram Protocol), IP (Internet Protocol) and RTP (Real Time Protocol) protocols Stated otherwise, the data to be transmitted are split up by the sender into data packets, transmitted across the Internet to the recipient and reassembled by the latter Each packet contains a destination address, referred to as the "IP address" (Internet Protocol) of the recipient, enabling the Internet to convey the packet to the recipient.
Generally, a communication terminal, not linked permanently to the Internet, is furnished with a dynamic IP address, stated otherwise an address which is not fixed, on the Internet A terminal's IP address, allocated by its access provider, is valid only temporarily Usually, it changes with each new connection of the terminal to the Internet.
In order for two terminals to communicate with one another, in real time, across the Internet, each terminal must know the IP address of the other terminal, something which proves to be difficult in so far as these IP addresses are temporary and hence nonregular.
A known solution for enabling conversing parties to talk via the Internet consists in going via a server for effecting communication, for example an IRC (Internet Relay Chat) server However, this solution proves to be constraining.
FR 2 753 862 also discloses a process for effecting communication, across the Internet, between a first and a second telephone apparatus, both linked to a digital line of a telephone network The first apparatus connects up to the Internet, by telephone connection to an Internet access provider, obtains an IP address and, whilst remaining connected to the Internet, transmits its IP address to the second apparatus, across the telephone network, using a second channel B of the digital line.
The implementation of the process of FR 2 753 862 presupposes that the first apparatus, the calling apparatus, is linked to a digital telephone line, comprising two data transmission channels B In fact, the calling apparatus uses one of the channels B to connect up to the Internet and the other channel B to transmit its IP address to the second apparatus, the called apparatus This solution is therefore appropriate only for users of a digital line, of the ISDN type (Integrated Services Digital Network).
The present invention proposes a solution which is also appropriate for communication terminals linked to an ordinary telephone line, a nondigital line, of the STN type (Switched Telephone Network).
For this purpose, the invention relates to a process for effecting communication between at least two communication terminals across a computer network, in which, the two terminals being linked to a telephone network, the first of the two terminals connects up to the computer network and obtains a computer address which it transmits to the second terminal across the telephone network, and the second terminal connects up to the computer network and obtains a computer address which it transmits to the first terminal across the computer network, process characterized in that before connecting up to the computer network, the first terminal calls the second terminal across the telephone network and invites it to call it back later, as agreed, the second terminal calls the first terminal later and the latter then transmits its computer address to it, across the telephone network.
Advantageously, after having obtained its computer address, the first terminal remains connected to the computer network, it is advised of the call of the second terminal across the telephone network by a call signal and then switches temporarily over to the second terminal so as to transmit its computer address to it across the telephone network.
Thus, if the first terminal is furnished with a dual-call signal service, it can use this service to transmit its computer address to the second terminal, whilst remaining connected to the computer network.
The invention also relates to a process for effecting communication between at least two communication terminals across a computer network, in which, the two terminals being linked to a telephone network, the first of the two terminals connects up to the computer network and obtains a computer -ddress which it transmits to the second terminal across the telephone network, and the second terminal connects up to the computer network and obtains a computer address which it transmits to the first terminal across the computer network, process characterized in that, after having obtained its computer address, the first terminal disconnects from the computer network, so as to transmit its computer address to the second terminal across the telephone network, then reconnects to the computer network and obtains the same computer address as at the previous connection.
Advantageously, after having disconnected from the computer network, the first terminal calls the second terminal across the telephone network so as to transmit its computer address to it.
It will be stressed that, in the two processes of the invention, the first terminal transmits its computer address to the second terminal, via an ordinary telephone communication between the two terminals, the establishing of this communication being performed either by telephone switching, or between a disconnection and a reconnection of the first terminal to the computer network.
The invention will be better understood with the aid of the following description of various embodiments of the process for effecting communication between two terminals across a computer network of the invention, with reference to the appended drawing in which:
Figure 1 represents a diagram of the two terminals and of the Internet; Figure 2 represents a functional block diagram of one of the communication terminals; Figure 3 represents a diagram of the various steps of the process for effecting communication, according to a first embodiment; Figure 4 represents a diagram of the various steps of the process, according to a second embodiment.
The process of the invention makes it possible to effect communication between two terminals T 1 and T 2, across a packet-switching computer network, in this instance the Internet 100.
Each terminal T 1, T 2 is linked to a telephone network, in this instance the switched telephone network STN 101, on which it has a telephone call number, and is furnished with access to the Internet provided by an Internet access provider IAP 1, l AP 2.
The two terminals T 1, T 2 being identical, only one will now be described.
The terminal T 1 comprises a data transmission line interface 1 which includes a modem for linking to the telephone network 101, a man/machine interface 2/7 and, in memory, an application for connection/disconnection to the Internet 100, an application for communication across the Internet 100 and an application for effecting communication across the Internet 100, respectively represented by the functional blocks 8, 11 and 12 All these elements are linked to a central control block 13, in this instance a processor, intended for executing the applications and for controlling the operation of the terminal T 1.
The man/machine interface comprises a microphone 3 linked to an analog/digital converter (ADC) 2, a loudspeaker 5 linked to a digital/analog converter (DAC) 4, a display screen 6 and an input keypad 7 The input keypad 7 comprises telephone keypad conventional alphanumeric keys as well as a specific key for effecting communication across the Internet 100, intended for triggering the execution of the application ( 12) for effecting communication across the Internet 100.
6 - The line interface 1 enables the terminal T 1 to communicate across the telephone network 101.
The application ( 8) for connection/- disconnection to the Internet 100 enables the terminal T 1 to connect up to the Internet 100, by telephone connection across the telephone network 101 to its access provider IAP 1, according to a connection procedure, or protocol, and to disconnect from the Internet 100, according to a disconnection procedure.
The application ( 11) for communication across the Internet 100 enables the terminal T 1 to communicate across the Internet 100 with a corresponding terminal, in real time and bidirectionally, by using Internet 100 communication protocols, in this instance the TCP, UDP, IP and RTP protocols In the particular example of the description, the application for communication across the Internet 100 consists of a telephony application enabling voice communication between the terminal T 1 and a corresponding terminal across the Internet 100.
Functionally, the block 11 for communication across the Internet 100 comprises a module 9 for splitting into data packets and for reassembling data and a compression/decompression module 10.
The module 9 is intended, on transmission, for splitting the data to be transmitted into data packets and, on reception, for reassembling the data from data packets received, according to the TCP, UDP, IP and RTP Internet protocols.
The compression/decompression module 10 is intended, on transmission, for compressing the data to be transmitted and, on reception, for decompressing the data received.
Thus, the terminal T 1, on transmission, compresses the data to be transmitted and splits them up into data packets, using the Internet protocols, and, on reception, reassembles the data packets received so as to recover the data sent, and decompresses the latter.
7 - It will be noted here that each data packet contains a destination computer address and an origin computer address on the Internet 100 The expression "computer address" is understood to designate an address on the Internet computer network 100, more commonly referred to as an "IP address" (standing for Internet Protocol) These IP addresses consist of a succession of digits and are used by the Internet 100 to convey the data packets to their recipient and occasionally the return them to their sender A communication terminal, connected to the Internet 100, has its own IP address on the Internet network 100, usually allocated by the terminal's Internet 100 access provider The IP addresses of the communication terminals are not generally fixed, but dynamic, stated otherwise are allocated temporarily to the terminals.
Stated otherwise, the IP address of a terminal changes fairly often, generally with each new connection of the terminal to the Internet 100.
The application ( 12) for effecting communication across the Internet 100 enables the terminal T 1 to engage in communication with a corresponding terminal across the Internet 100, according to a procedure for effecting communication which will be more explicitly set out in the description of the process for effecting communication.
Functionally, the block 12 for effecting communication comprises in particular a module for receiving an IP address and for transmitting the latter by telephone, and intended for receiving the IP address of the terminal T 1, after connection of the latter to the Internet 100, and for retransmitting it to a corresponding terminal by telephone transmission across the telephone network 101.
The process for effecting communication between the two terminals T 1 and T 2, across the Internet 100, will now be described, with reference to Figure 3.
The terminal T 1 is furnished here with a dual- call signal service This service, provided by the 8 - operator of the telephone network 101, enables the terminal T 1 to be adviseed, in the course of a telephone communication with a first corresponding party, of the telephone call of a second corresponding party, through the receiving of a call signal, and, as appropriate, to temporarily switch over to the second corresponding party, whilst alerting the first corresponding party.
In order to talk to a user of the terminal T 2 across the Internet 100, a user of the terminal T 1 inputs the telephone call number of the terminal T 2, with the aid of the input keypad 7, and presses the key for effecting communication across the Internet 100.
The steps which will now be described are performed by the terminals T 1 and T 2, here automatically (that is to say without the intervention of their users), by executing their application for effecting communication across the Internet 100 It will be noted from the outset that the two terminals T 1 and T 2 communicate with one another across the telephone network 101 via protocol frames.
The terminal T 1 calls the terminal T 2 across the telephone network 101 (step 20) On receiving this call, the terminal T 2 puts the telephone line off-hook and the two terminals engage in a telephone communication, across the telephone network 101, in the course of which the terminal T 1 asks the terminal T 2 whether it wishes to communicate with it and in real time across the Internet 100 (step 21).
The terminal T 2 then triggers the execution of its application for effecting communication across the Internet 100 and informs the terminal T 1 that it agrees to communicate with it across the Internet 100.
In case of refusal to communicate with the terminal T 1 across the Internet 100, the terminal T 2 will inform the terminal T 1 thereof and the latter will end the procedure for effecting communication across the Internet 100 (step 22).
After having received the agreement of the terminal T 2, the terminal T 1 invites the latter to call it back later, here one minute afterward, across the telephone network 101 (step 23), then interrupts the telephone communication by placing the telephone line back on-hook (step 24).
The calling terminal T 1 then connects up to the Internet 100, by telephone connection to its access provider IA Pl across the telephone network 101, by executing the application 8 for connection/- disconnection to the Internet 100 (step 25) Upon connection, the terminal T 1 obtains and receives an IP address, which will be referred to as the "address IP 1 '" in what follows, allocated by the access provider IAP 1.
After having obtained its address IP 1, the terminal T 1 remains connected to the Internet 100 and waits for the call from the terminal T 2.
As agreed, the terminal T 2 calls the terminal T 1 across the telephone network 101 one minute after the call from the terminal T 1 to the terminal T 2 (step 26).
The terminal T 1 being connected to the Internet 100 by a telephone link with its access provider IAP 1, its telephone line is busy Nevertheless, it is adviseed of the incoming call of the terminal T 2 by the receiving of a call signal (step 27), sent by the dual-call signal service After receiving the dual-call signal, the terminal T 1 sends the access provider IA Pl a specific alerting frame, via which the terminal T 1 asks the access provider IA Pl to wait without interrupting their telephone communication, for a specified duration, here for a few minutes The terminal T 1 then temporarily switches over to the calling terminal T 2 so as to establish a telephone communication therewith across the telephone network 101, in the course of which the terminal T 1 transmits its address IP, to the terminal T 2 (step 28) It will be stressed that, during the telephone communication between the terminal T 1 and the terminal T 2, the terminal T 1 puts its access provider IA Pl on standby and therefore remains - connected to the Internet 100 The terminal T 1 then again switches over to the Internet 100 and interrupts the telephone communication with the terminal T 2.
After having obtained the address IP, of the terminal T 1, the terminal T 2 connects up in turn to the Internet 100, by telephone connection to its access provider IAP 2, across the telephone network 101, by executing the application for connection/disconnection to the Internet 100 (step 29) Upon connection, it obtains an IP address, which will be referred to as "address IP 2 " in what follows, allocated by the access provider l AP 2.
After connection to the Internet 100, the terminal T 2 engages in communication in real time, across the Internet 100, with the terminal T 1 by sending it first data packets containing the address IP 2 of the terminal T 2 (step 30) The terminal T 2 thus transmits its address IP 2 to the terminal T 1 across the Internet 100 The two terminals T 1 and T 2 henceforth each know the IP address of the other and can therefore communicate with one another in real time across the Internet 100, by exchanging data packets The terminals T 1 and T 2 then each transmit a signal, here a sound signal, to advise their users that they can talk to one another across the Internet 100, as with an ordinary telephone.
The communication between the two terminals T 1 and T 2 (step 31) unfolds in a known manner On transmission, the voice is input with the aid of the microphone 3 and then digitized ( 2) into voice data which are compressed ( 10) and thereafter placed into packets ( 9) before being sent to the Internet 100 which conveys the packets to the recipient On reception, the data packets received are reassembled ( 9) into voice data which are decompressed ( 10) and then converted into analog signals ( 4) transmitted by the loudspeaker 5.
If, in step 26, the terminal T 2 calls the terminal T 1, while the latter is connecting up to the 11 - Internet 100 and has not yet obtained an IP address, the terminal T 1 temporarily switches over to the terminal T 2 while alerting the access provider IAP 1, and asks the terminal T 2 to call it back later.
If the terminal T 1 does not succeed in connecting up to the Internet 100 and hence in obtaining an IP address, on receiving the call of the terminal T 2 (step 26), it puts the telephone line off- hook and informs the terminal T 2 of its failure to connect to the Internet 100.
A second embodiment of the process for effecting communication will now be described, with reference to Figure 4 For the sake of clarity, only the steps of this second embodiment which differ from those of the first embodiment described above will now be explained.
Under the control of a user, the terminal T 1 calls the terminal T 2 across the telephone network (step 40) and asks it whether it wishes to communicate with it across the Internet 100 (step 41).
As appropriate, the terminal T 2 informs the terminal T 1 that it agrees to communicate with it across the Internet 100 The terminal T 1 then invites the terminal T 2 to call it back later, here one minute afterward, across the telephone network 101 (step 43), then interrupts the telephone communication by putting the telephone line back on-hook (step 44).
In case of refusal of the terminal T 2 to communicate across the Internet 100 with the terminal T 1, the latter would end the procedure for effecting communication across the Internet 100 (step 42).
The calling terminal T 1 thereafter connects up to the Internet 100 (step 45) and, via a specific frame of the Internet 100 connection protocol, addresses a request to its access provider IA Pl so as to obtain the same computer address for two successive connections, the current one and the following one On connection, the terminal T 1 obtains and receives an IP address ("address I Pl'') It then disconnects from the Internet 12 - (step 46), interrupting the telephone communication with its access provider IA Pl consequently freeing its telephone line, and waits for the call from the terminal T 2.
As agreed, the terminal T 2 calls the terminal T 1 across the telephone network 101 one minute after the call from the terminal T 1 to the terminal T 2 (step 47).
On receiving this call, the terminal T 1 puts the telephone line off-hook and the two terminals T 1 and T 2 establish a telephone communication, across the telephone network 101, in the course of which the terminal T 1 transmits its address IP, to the terminal T 2 The terminal T 1 then interrupts the telephone communication by putting the line back on-hook.
The two terminals T 1 and T 2 then connect up to the Internet 100, by telephone connection to their respective access providers IA Pl and IAP 2 (steps 49 and 50) The terminal T 1 obtains and receives, as agreed, the same address I Pl as at its previous connection, and the terminal T 2 obtains and receives an IP address ("address IP 2 ") - After connection to the Internet 100, the terminal T 2 engages in communication in real time, across the Internet 100, with the terminal T 1 by sending the latter first data packets containing the address IP 2 of the terminal T 2 The terminal T 2 thus transmits its address IP 2 to the terminal T 1 across the Internet 100 (step 51) Each terminal T 1 and T 2 knowing the IP address of the other terminal, they communicate with one another, in real time, across the Internet 100, by exchanging data packets (step 52).
If, in step 47, the terminal T 2 calls the terminal T 1 while the latter is still communicating with the access provider IAP 1, the terminal T 2 obtains a busy signal and then decides to call back later.
If the terminal T 1 does not succeed in connecting up to the Internet 100 and hence in obtaining an IP address, on receiving the call from the terminal T 2 (step 26), it puts the telephone line off- 13 - hook and informs the terminal T 2 of its failure to connect to the Internet 100.
In a variant embodiment, the calling terminal T 1 does not call the terminal T 2 across the telephone network 101 before its first connection to the Internet to obtain the address I Pl (step 45) After having obtained its address IP 1, the terminal T 1 disconnects from the Internet 100 and calls the terminal T 2 across the telephone network 101 After establishment of the telephone communication between the two terminals T 1 and T 2, the terminal T 1 asks the terminal T 2 if it wishes to communicate with it in real time across the Internet and, as appropriate, transmits its address I Pl to it across the telephone network 101 The two terminals T 1 and T 2 then interrupt their telephone communication and connect up to the Internet 100, by telephone connection to their access provider IA Pl and IAP 2 As agreed at the first connection, the terminal T 1 obtains and receives the same address IP 1 The terminal T 2 obtains and receives an address IP 2 which it transmits to the terminal T 1 across the Internet 100, thereby engaging in communication across the Internet 100.
It would also be possible to envisage the terminal T 1 calling the terminal T 2 across the telephone network 101 before its first connection to the Internet so as to obtain the address I Pl (step 45), solely in order to ask it whether it wishes to communicate with it across the Internet 100 and, after having obtained this address IP 1, disconnecting from the Internet 100 and again calling the telephone T 2 across the telephone network 101 so as to transmit its address I Pl to it.
The terminal T 1 could also address a request to its access provider IA Pl so as to obtain the same IP address for a specified duration In this case, the access provider IA Pl would allocate the terminal T 1 the same address I Pl for a plurality of successive connections, in so far as they occur within the predetermined time span As a variant, the access 14 - provider could allocate the terminal T 1 the same IP address, implicitly (that is to say without express request by the terminal T 1), for several successive connections of the terminal T 1, in so far as these connections occur within a predetermined time span.
In the foregoing description, all the steps of the process for effecting communication are executed automatically by the terminals There could also be provision for at least some of these steps to be executed by operators, users of the terminals.
In the particular example of the description, the communication established across the Internet 100 is a voice communication It could of course pertain to any other type of communication, especially a telefax communication.
Instead of the STN telephone network 101, it would be possible to envisage any other type of telephone network, for example a wire, cellular or satellite network.
Finally, the process for effecting communication of the invention could also be used to effect communication between more than two terminals.
