Title: Method for creating internet network access accounts

Description:
TECHNICAL FIELD OF THE INVENTION 
     The aim of the invention is a method for creating accounts for accessing the Internet network. 
     Notably it relates to the technical field of Internet handler networks and more specifically to the exchange of data conveyed by the Internet. 
     Prior Art 
     Patent document US 2006/0259927 (ACHARYA) describes a technique for handling television or radio services while roaming. The technique described enables a user to access television or radio services to which he is subscribed even when he is away from his place of residence. Said document describes a network for distributing television or radio signals. 
       FIG. 1  schematizes the arrangement of the main elements constituting an Internet handler network known by the person skilled in the art. 
     Said type of network generally comprises a telephone center wherein terminate the lines of the subscribers A and B, regardless of their Internet access provider (or operator). Said telephone center is commonly known as MDF (Main Distribution Frame). The MDF usually comprises a distribution frame R, and an unbundling room where the DSLAM A , DSLAM B  of the Internet access providers are reunited. The distribution frame R is adapted to sort the transmission lines (copper, coaxial cables, optical fibers, satellites, etc.) L A , L B  of the subscribers A and B. The transmission lines L A , L B  are thus sorted in the distribution frame R in order to subsequently be relayed towards the respective DSLAM A , DSLAM B  of the Internet access providers, via optical fibers L FA , L FB . By way of example, the DSLAM A  is an item of equipment of the Orange® Internet access provider and the DSLAM B  is an item of equipment of the SFR® Internet access provider. 
     The DSLAM (Digital Subscriber Line Access Multiplexer) are equipment making the connection between the transmission lines L A , L B  of subscribers A and B and Internet. Once concentrated in the DSLAM A , DSLAM B , the numerical data transported by the transmission lines L A , L B  are dispatched to the various Internet networks RI A , RI B  respectively managed by the Internet access providers. 
     Sub-distribution frames SR A , SR B  may be installed in the MDF, said sub-distribution frames being specific to each provider and make it possible to create the interface between the main distribution frame R and the ports of the DSLAM A , DSLAM B . 
     The terminating point P A , P B  is the physical access point by which a subscriber A, B obtains the access to the Internet network RI A , RI B . Said terminating point P A , P B  is in general located in the premises (dwelling, offices, etc.) of the subscriber A, B. It is intended to separate the local loop of the internal handler from the premises of the subscriber A, B. Said local loop is the portion of transmission line L A , L B  located between the terminating point P A , P B  and the central distribution frame R. The terminating point P A , P B  thus authorizes the transmission of numerical data to the internal handler. 
     The internal handler of each subscriber A, B may be provided with a native modem-router MR A , MR B . Each modem-router MR A , MR B  makes it possible to establish a connection between one or more items of electronic equipment E A , E B  and the Internet network RI A , RI B . Said items of equipment E A , E B  are, for example, a fixed or portable computer, a tablet, a Smartphone, a television, a home automation device, etc. The numerical data traveling between the internal handler of the subscriber A, B and the Internet network RI A , RI B , are directed via the modem-router MR A , MR B  and travel on the corresponding transmission line L A , L B . The distribution frame R transports said data towards the corresponding DSLAM A , DSLAM B  which subsequently transfers same towards the associated Internet network RI A , RI B . The communication between the modem-routers MR A , MR B  and the DSLAM A , DSLAM B  is, for example, performed using the ADSL (Asymmetric Digital Subscriber Line) technology. 
     Each subscriber A, B is holder of an account for accessing the Internet network RI A , RI B , the account of which is attributed by the provider with which said subscriber is affiliated. Said access account brings into play a plurality of connection parameters adjusted in order to adapt the numerical data intended for or emitted by the items of equipment E A , E B  of the subscriber A, B to the specific configuration of the Internet network RI A , RI B  of the provider and/or to a parametrization specific to said subscriber (e.g.: parental control, firewall, etc.). Therefore, it can be considered that the numerical data output or input from a terminating point are associated with the connection parameters of the access account of the subscriber. 
     Each access provider attributes unique connection parameters to its subscribers. Said connection parameters notably include a unique subscriber identifier (the equivalent of an IMSI (International Mobile Subscriber Identity) identifier), a private security key (e.g.: WEP, WAP, WAP2 key, etc.) and optionally certain rights and/or restrictions open to the subscribers A, B, for example, access rights to pay-per-view television channels, a parental control, a firewall, etc. Each subscriber A, B therefore parametrizes his native modem-router MR A , MR B  with his own connection parameters. Each item of equipment E A , E B  of the subscriber A, B then connects to the respective native modem-router MR A , MR B  with the private security key and identifies itself with said native modem-router with its MAC (Media Access Control) address. 
     The routing rules mean that in a configuration such as described in  FIG. 1 , the response to a request passing through a terminating point will inevitably use the same terminating point at the time of the return thereof. Furthermore, a terminating point can only be the subject of a single subscription. The subscriber cannot take a subscription with an access provider if he is already subscribed to another. 
     By way of example, let us take the case where the subscriber A rents all or part of his dwelling premises to the subscriber B, said rental being, for example, carried out from a platform of the Airbnb® type. The connection parameters of the access account of the subscriber B open thereto, for example, the access rights to pay-per-view television channels, which rights are not authorized with the connection parameters of the access account of the subscriber A. 
     The subscriber B can only connect to Internet if the subscriber A communicates thereto his own connection parameters in order that the items of equipment E B  of the subscriber B can be recognized by the modem-router MR A  and communicate with said latter. All of the numerical data exchanged from the items of equipment of the subscriber B will then travel via the Internet network RI A  of the provider of the subscriber A. This has certain risks for the subscriber A, for example, in the case where the subscriber B exchanges sensitive data and/or visits prohibited Internet sites, since it is not possible to identify and to track the data exchanges initiated by the subscriber B from same initiated by the subscriber A. Also, the subscriber A practically never communicates his connection parameters to the subscriber B, said latter then being deprived of Internet access. And even if the subscriber A communicates his connection parameters to the subscriber B, said latter will not be able to benefit from his own rights and/or restrictions (access rights to pay-per-view television channels, parental control, firewall, etc.). 
     The invention aims to overcome this state of things. In particular, one aim of the invention is to be able to create distinct accounts for accessing the Internet network through a unique terminating point of a premises provided with an internal handler. 
     Another aim of the invention is to be able to create said distinct accounts in a simple, reliable, automated, secure manner. 
     An additional aim of the invention is to be able to identify and track the data exchanges associated with each of the distinct Internet network access accounts. 
     DISCLOSURE OF THE INVENTION 
     The solution proposed by the invention is a process for creating accounts for accessing the Internet network through a unique terminating point of a premises provided with an internal handler, the terminating point is adapted to authorize the transmission of numerical data to the internal handler, the numerical data are associated with connection parameters of a first native Internet network access account of a first subscriber. The method comprises the steps of:
         transmitting to the internal handler, through the terminating point, in addition to the numerical data associated with the connection parameters of the native account of the first subscriber, other numerical data associated with connection parameters of a second Internet network access account of a second subscriber,
           the connection parameters of the second account are different from the connection parameters of the first native account.   
               

     So that each of the two subscribers can connect to the Internet network with his own connection parameters through the terminating point shared between the two said subscribers, the method further comprises the steps of:
         parametrizing a modem-router with the connection parameters of the second account,   connecting the modem-router to the internal handler,   transmitting to the modem-router a session authorization signal authorizing said modem-router to process the numerical data associated with the connection parameters of the second account and which travel through the terminating point, which signal is emitted from an item of equipment of the Internet access provider of the first subscriber.       

     By using the aforementioned example, the subscriber A has his own native account and can continue to use same to access the Internet network of his provider. The modem-router (same of the subscriber A or another dedicated modem-router) is parametrized with the connection parameters of the subscriber B. Said latter can then connect to the Internet network of his own provider, with his own connection parameters, and by using the terminating point of the subscriber A that is now shared. The numerical data output or input from the terminating point of the subscriber A are associated with the connection parameters of the native account and with the connection parameters of the account of the subscriber B. 
     Other advantageous features of the invention are listed hereinbelow. Each one of these features can be considered individually or combined with the remarkable features defined hereinabove, and may be the subject matter, where applicable, of one or more divisional patent applications:
         Advantageously: —the modem-router generates an authentication request containing identification data of the second access account and transmits said authentication request to an item of equipment of the Internet access provider of the first subscriber, the connection of said modem-router to the internal handler, or the insertion of a secure removable media device into a connection interface of said modem-router, being the element triggering the generation and the transmission of said authentication request; —the item of equipment of the Internet access provider of the first subscriber generates and transmits to an item of equipment of the Internet access provider of the second subscriber a polling request aiming to verify that said second subscriber is indeed affiliated with the access provider identified in the authentication request, the receipt of the authentication request being the element triggering the generation and the transmission of said request; —the item of equipment of the Internet access provider of the second subscriber verifies that said second subscriber is indeed affiliated with the access provider identified in the authentication request, the receipt of the polling request being the element triggering the verification procedure; and, in case of positive verification, the item of equipment of the Internet access provider of the second subscriber generates and transmits to the item of equipment of the Internet access provider of the first subscriber an authorization signal; —the receipt of the authorization signal results in the generation and the transmission of the session authorization signal, by the item of equipment of the Internet access provider of the first subscriber to the modem-router.   The method advantageously includes a step of connecting the terminating point to a transmission line connected to an item of equipment of an Internet access provider managing the native account and multiplexing said transmission line so that the numerical data associated with the connection parameters of the second account of the second subscriber and the numerical data associated with the connection parameters of the native account of the first subscriber simultaneously travel through said transmission line.   The method advantageously includes a step of integrating into the session authorization signal data relating to the connection parameters of the second account, the receipt of said session authorization signal by the modem-router, resulting in the automatic parametrization of said modem-router with said connection parameters.   In one alternative embodiment, the method advantageously includes a step of parametrizing the modem-router: —by connecting the modem-router to an electronic device serving as interface; —then by manually entering the connection parameters of the second account through said electronic device acting as interface; —and by saving said connection parameters in a memory of the modem-router.   In one alternative embodiment, the method advantageously includes a step of parametrizing the modem-router: —by connecting the modem-router to another modem-router already parametrized with the connection parameters of the second account; —and copying all of the connection parameters saved in the other modem-router in a memory of the modem-router.   In one alternative embodiment, the method advantageously includes a step of: —saving in a secure removable media device the connection parameters of the second account; —equipping the modem-router with a connection interface adapted to receive the secure removable media device; —the insertion of the secure removable media device into the connection interface is a triggering element resulting in the automatic parametrization of the modem-router with the connection parameters of the second account saved in said media device.   In one alternative embodiment, the method advantageously includes a step of: —saving in a secure removable media device the identification data of the second account; —equipping the modem-router with a connection interface adapted to receive the secure removable media device; —the insertion of the secure removable media device into the connection interface is a triggering element resulting in the automatic implementation of a logical computer process leading to the automatic parametrization of the modem-router with the connection parameters of the second account.   The method advantageously includes a step of connecting the modem-router between the terminating point and a native modem-router connected to the internal handler, which native modem-router is parametrized with the connection parameters of the first native account, an item of equipment of the second subscriber not being able to communicate with said native modem-router without knowledge of the connection parameters of the first native account and an item of equipment of the first subscriber not being able to communicate with said modem-router without knowledge of the connection parameters of the second account.   The method advantageously includes a step of receiving in the native modem-router, the numerical data associated with the connection parameters of the first native account and the numerical data associated with the connection parameters of the second account which travel through the terminating point, and only processing in said native modem-router the numerical data associated with the connection parameters of the first native account.   In one alternative embodiment, the method advantageously includes a step of: —receiving in the modem-router, the numerical data associated with the connection parameters of the first native account and the numerical data associated with the connection parameters of the second account which travel through the terminating point; —only processing in said modem-router the numerical data associated with the connection parameters of the second account; —sending back towards the native modem-router and from said modem-router, the numerical data associated with the connection parameters of the first native account.   Advantageously, the connection of the modem-router to the internal handler is a triggering element resulting in the automatic implementation of a logical computer process leading to the multiplexing of the transmission line.   Advantageously, the disconnection of the modem-router from the internal handler is a triggering element resulting in the automatic implementation of a logical computer process leading to the stopping of the multiplexing of the transmission line.   Advantageously, the insertion of the secure removable media device into the connection interface is a triggering element resulting in the implementation of a logical computer process leading to the multiplexing of the transmission line.   Advantageously, the withdrawal of the secure removable media device from the connection interface is a triggering element resulting in the automatic implementation of a logical computer process leading to the stopping of the multiplexing of the transmission line.   The method advantageously includes a step of parametrizing the modem-router with the connection parameters of the second account and with the connection parameters of the first native account so that said modem-router processes the numerical data associated with the connection parameters of the first native account and the numerical data associated with the connection parameters of the second account, and which travel through the terminating point, said modem-router being adapted to be used simultaneously by the first subscriber and the second subscriber, same keeping their own Internet network access accounts and their own connection parameters.   Advantageously, in response to the receipt of the session authorization signal, the modem-router generates and transmits a session electronic signature to an item of equipment of the Internet access provider of the second subscriber and/or to the Internet access provider of the first subscriber, which signature is used to track the connection histories of said second subscriber when he uses the modem-router from the internal handler of the dwelling of said first subscriber.

     PREFERRED EMBODIMENTS OF THE INVENTION 
     The method subject matter of the invention consists of a coherent sequence of steps for achieving a desired result. These steps result in the handling of physical elements, notably signals (electric or magnetic) capable of being stored, transferred, combined, compared, etc. 
     The method is implemented through the intermediary of computer applications run by computer devices. In the interest of clarity, it should be understood within the meaning of the invention that “the device does something” means “the computer application run by the processor or microprocessor of the device does something”. Just like “the computer application does something” means “the computer application run by the processor or microprocessor of the device does something”. 
     Again, in the interest of clarity, the present invention makes reference to one or more “logical computer processes”. Said latter correspond to the actions or results obtained by the running of instructions of various computer applications. Also, it should also be understood within the meaning of the invention that “a logical computer process does something” means “the instructions of one or more computer applications run by one or more processors or microprocessors do something”. 
     The implementation of the method subject matter of the invention requires the use of a modem-router MR′. Said latter may be in the form of a box of relatively reduced dimensions, having, at most, the overall size of an Internet box. 
     By referring to  FIG. 4 , the modem-router MR′ notably comprises one or more processors or microprocessors  50 , one or more memories  51 , a network interface  52 , which are mutually connected via a bus  53 . One or more computer applications—or computer programs—are saved in the memory or memories  51  and the instructions of which, when they are run by the processor or processors  50  make it possible to produce the functions described above in the description and notably the modulation, demodulation, multiplexing, demultiplexing of numerical data. 
     The memory or memories  51  must be considered as a storage device also adapted to store data and/or data files. It may concern a native memory or an add-on memory such as a Secure Digital (SD) card. The MAC address of the modem-router MR′ is saved in the memory  51 , said MAC address being unique is pre-saved in the factory. 
     The network interface  52  is a wired or wireless communication interface adapted to establish a communication with the items of equipment E B  of the subscriber B, by using, for example, a private security key (e.g.: WEP, WAP, WAP2 key, etc.). The network interface  52  may, for example, comprise a Wi-Fi transmitter/receiver, an Ethernet connection, a PLC (Power-line Communication) connection, a Bluetooth module, or any other means of connection to the modem-router MR′. In general, the network interface  52  has the function of managing the connections between the modem-router MR′ and the items of electronic equipment E B  of the subscriber B. 
     The modem-router MR′ may be parametrized beforehand with the connection parameters of an Internet network access account. In order to follow the aforementioned example, the modem-router MR′ is, for example, parametrized with the connection parameters of the subscriber B. Said connection parameters notably include the unique identifier of the subscriber B, an item of identification data of the Internet access provider of the subscriber B (which indication may be included in the unique identifier), a private security key (e.g.: WEP, WAP or WAP2 key) and optionally certain rights and/or restrictions open to the subscriber B (e.g.: access rights to pay-per-view television channels, parental control, firewall, landline telephone number, etc.). 
     Said parametrization of the modem-router MR′ may be performed in the dwelling of the subscriber B, prior to his installation in the dwelling of the subscriber A. Said parametrization may also be performed directly in the dwelling of the subscriber A. Various parametrization methods are then possible. 
     The subscriber B may, for example, use a computer or a Smartphone (or another electronic device) that he connects in a wired (for example, with an Ethernet cable) or wireless (for example, by Wi-Fi) manner to the modem-router MR′. Said computer or said Smartphone acts as interface so that the subscriber B enters his connection parameters manually. Said connection parameters thus input are saved in the memory  51  of the modem-router MR′. 
     In an alternative embodiment, the subscriber B connects in a wired (for example, with an Ethernet cable) or wireless (for example, by Wi-Fi) manner the modem-router MR′ to his native modem-router MR B . In response to said connection, or in response to the activation of a dedicated key installed on the box of the modem-router MR′, all of the connection parameters saved in the native modem-router MR B  are copied in the memory  51  of the modem-router MR′. 
     In another alternative embodiment, the connection parameters may be saved in a secure removable media device such as a smart card, SIM (Subscriber Identity Module) card, SD (Secure Digital) card or a USB (Universal Serial Bus) stick. The Internet access provider of the subscriber B may provide him with said pre-parametrized media device that can then be inserted into a generic modem-router MR′ purchased in a store by the subscriber B. Said card may also be inserted into a generic modem-router MR′ purchased in a store by the subscriber A and installed in the dwelling of said latter as explained above in the description in reference to  FIGS. 10 and 11 . The subscriber B is thus only recognized by his data registered on his removable media device, and not by his physical or geographic place of residence as in prior art. 
     In  FIGS. 2 and 3 , the modem-router MR′ is connected during line cutoff, between the terminating point P A  of the dwelling of the subscriber A and the native modem-router MR A  of said subscriber A. Said solution has the advantage, for the subscriber A, of keeping his native modem-router MR A . It is reminded that the modem-router MR′ may be installed either by the subscriber A, or by the subscriber B at the time of his installation in the dwelling of the subscriber A. 
     The connection of the modem-router MR′ during line cutoff is schematized in  FIG. 5 . For example, a telephone plug adapter, referenced P′, is used and advantageously an ASDL telephone plug adapter, the male part of which is connected to the female part of the physical T-plug installed in the wall of the dwelling and forming the terminating point P A . The modem-router MR′ is connected to said telephone plug adapter P′, for example, by means of an RJ11 cable. The female part of the telephone plug adapter P′ is connected to the male part of the T-plug, referenced P, to which is connected a native modem-router MR A . The connection between the plug P and the native modem-router MR A  may also be produced by means of an RJ11 cable. 
     The subscribers A and B may each have a different Internet access provider. For example, the subscriber A is affiliated with Orange® and the subscriber B is affiliated with SFR®. The DSLAM A  and DSLAM B  may be located in the same MDF or in MDFs that are distinct and remote from one another. 
     In  FIG. 2 , a multiplexing is performed at the main distribution frame R so as to simultaneously pass through the transmission line L A  of the subscriber A, not only the numerical data associated with the connection parameters of the subscriber A, but also the numerical data associated with the connection parameters of the subscriber B. Said various data therefore pass through the transmission line L A  and through the terminating point P A  at the same time. Said multiplexing is preferably a frequency multiplexing. A multiplexer R MUX  installed in the distribution frame R provides the multiplexing of the transmission lines L A  and L B . Optical fibers L FA  and L FB  linking the distribution frame R respectively to the DSLAM A  and to the DSLAM B  are connected to the inputs of the multiplexer R MUX . The transmission line L A  for its part is connected to the output of the multiplexer R MUX . 
     On the alternative embodiment in  FIG. 6 , the multiplexing is performed at the sub-distribution frame SR A . The optical fibers L FA  and L FB  from the DSLAM A  and DSLAM B  are connected to the inputs of the multiplexer SR MUXA . The optical fiber L FA  linking the sub-distribution frame SR A  to the distribution frame R is connected to the output of the multiplexer SR MUXA . 
     On another alternative embodiment in  FIG. 7 , the multiplexing is performed directly in the DSLAM A . The optical fibers L FA  and L FB  are connected to the inputs of the multiplexer DSLAM MUXA . The optical fiber L FA  linking the DSLAM A  to the sub-distribution frame SR A  is connected to the output of the DSLAM MUXA  multiplexer. 
       FIG. 8  illustrates various steps implemented in the method subject matter of the invention.
         Event 1: The modem-router MR′ is parametrized with the connection parameters of the Internet network access account of the subscriber B.   Step 2: Connection of the modem-router MR′ during line cutoff, between the terminating point P A  and the native modem-router MR A  of said subscriber A. This Step 2 may be implemented before or after Event EV1.   Step 3: The modem-router MR′ generates and transmits an authentication request to the Internet access provider of the subscriber A. The connection of the modem-router MR′ to the internal handler is the element triggering the generation and the transmission of the authentication request. Said authentication request is transmitted via the transmission line L A , preferably in destination of the DSLAM A . Nevertheless, the authentication request may be transmitted to another item of equipment of the Internet access provider of the subscriber A, for example, a dedicated Internet server. Said authentication request notably contains numerical data corresponding to the MAC address of the modem-router MR′, the unique identifier of the subscriber B and an item of identification data of the Internet access provider of the subscriber B, and more generally contains identification data of the access account of the subscriber B.   Step 4: The Internet access provider of the subscriber A generates and transmits to the Internet access provider of the subscriber B, a polling request aiming to verify that the subscriber B is indeed affiliated with the access provider identified in the authentication request. The receipt of the authentication request is the element triggering the generation and the transmission of the polling request. Said polling request may contain all or part of the numerical data contained in the authentication request. In the figures attached, it is the DSLAM A  that generates and transmits the polling request to the DSLAM B , the communication between the DSLAM A  and the DSLAM B  being schematized by the dotted line. The generation and the transmission of the polling request may be initiated from another item of equipment of the Internet access provider of the subscriber A and/or transmitted to another item of equipment of the Internet access provider of the subscriber B, for example, a dedicated server. The communication between the two providers is therefore not necessarily produced between the respective DSLAM thereof but may involve other equipment.   Step 5: The Internet access provider of the subscriber B verifies that said subscriber B is indeed affiliated therewith. The receipt of the polling request is the element triggering the verification procedure. In the figures attached, it is the DSLAM B  that performs said verification, but said task may be produced by another item of equipment of the Internet access provider of the subscriber B. In practice, said verification consists of polling a table stored in a database, said table comprising a list of identification data associated with respective subscriber access accounts. If the identification data are stored in the table, the Internet access provider of the subscriber B generates and transmits to the Internet access provider of the subscriber A an authorization signal. In the figures attached, it is the DSLAM B  that generates and transmits the authorization signal to the DSLAM A .   Event 6: In response to the receipt of the authorization signal, the Internet access provider of the subscriber A opens access rights to the subscriber B. The receipt of the authorization signal is the element triggering the opening of access rights. Said access rights are notably access rights to his equipment, which rights may, for example, be limited over time (Internet session limited over a period of 1 day to 15 days, for example) and/or restricted to a portion of bandwidth. To this end, the subscriber A may, via the interface of a dedicated Internet site, tell his access provider beforehand that he plans to rent his dwelling for a given period, that the sharing of his terminating point P A  is only authorized for said period, for only a portion of his bandwidth.   Step 7: The Internet access provider of the subscriber A generates and transmits to the multiplexer MUX (R MUX , SR MUXA  or DSLAM MUXA ), a control signal in order to multiplex the transmission line L A  of the subscriber A, so as to simultaneously pass through said line (and therefore the terminating point P A ) not only the numerical data associated with the connection parameters of the subscriber A, but also the numerical data associated with the connection parameters of the subscriber B. In  FIG. 8 , it is the DSLAM A  that generates and transmits said control signal.   Step 8: The Internet access provider of the subscriber A generates and transmits to the modem-router MR′, a session authorization signal. In  FIG. 8 , it is the DSLAM A  that generates and transmits said session authorization signal.   Step 9: The item or items of equipment E B  of the subscriber B can now connect to the modem-router MR′, via a wired (e.g.: Ethernet) or wireless (e.g.: Wi-Fi) connection and navigate on the Internet with the connection parameters of said subscriber B. The item or items of equipment E B  of the subscriber B may notably communicate with the modem-router MR′, via the interface  52 , with the private security key (e.g.: WEP, WAP or WAP2 key) associated with the connection parameters of said subscriber B ( FIG. 3 ). However, the subscriber B not knowing the connection parameters of the access account of the subscriber A, and notably his private security key, the item or items of equipment E B  of the subscriber B cannot communicate with the native modem-router MR A . And vice versa for the items of equipment E A  of the subscriber A that cannot communicate with the modem-router MR′. The requests emitted by an item of equipment E B  of the subscriber B pass through the terminating point P A , via the modem-router MR′, and travel through the transmission line L A  up to the multiplexer R MUX , SR MUXA  or DSLAM MUXA . Said latter orients said requests towards the items of equipment of the Internet access provider of the subscriber B and in particular towards the DSLAM B  which transfers same subsequently towards the Internet network RI B . The numerical data of responses to said requests (e.g.: access to pay-per-view television channels, parental control, firewall, landline telephone number, etc.), return towards the Internet network RI B , then towards the DSLAM B  up to reaching the multiplexer R MUX , SR MUXA  or DSLAM MUXA  where they are multiplexed in order to travel through the transmission line L A  and pass back through the terminating point P A  and reach the modem-router MR′. In the case where requests are emitted at the same time by an item of equipment E A  of the subscriber A and by an item of equipment E B  of the subscriber B, the multiplexer R MUX , SR MUXA  or DSLAM MUXA , performs a demultiplexing so that: the requests emitted by an item of equipment E A  are oriented towards the items of equipment of the Internet access provider of the subscriber A and the requests emitted by an item of equipment E B  are oriented towards the items of equipment of the Internet access provider of the subscriber B. The return data travel through the same path.   Step 10: When the modem-router MR′ is disconnected from the internal handler of the dwelling of the subscriber A, a disconnection signal is transmitted to the Internet access provider of the subscriber A. The disconnection of the modem-router MR′ is therefore the element triggering the generation and the transmission of the disconnection signal. The modem-router MR′ may, for example, automatically emit said disconnection signal. Said disconnection signal is transmitted via the transmission line L A , preferably in destination of the DSLAM A . The DSLAM A  (or another item of equipment of the Internet access provider of the subscriber A) may also poll the modem-router MR′ by periodically transmitting thereto presence requests (“are you present?”). While the modem-router MR′ responds to said requests, the DSLAM A  deduces that said modem-router is indeed connected to the internal handler of the dwelling of the subscriber A. And, in the absence of response, the DSLAM A  deduces that the modem-router MR′ is disconnected from the internal handler of the dwelling of the subscriber A. In another alternative embodiment, it is the modem-router MR′ that periodically transmits to the DSLAM A  (or to another item of equipment of the Internet access provider of the subscriber A) presence messages (“I am present”). While the DSLAM A  receives said messages, it deduces that the modem-router MR′ is indeed connected to the internal handler of the dwelling of the subscriber A. And in the absence of receipt of said messages, the DSLAM A  deduces that the modem-router MR′ is disconnected from the internal handler.   Step 11: When the Internet access provider of the subscriber A is informed of the disconnection of the modem-router MR′, it generates and transmits to the Internet access provider of the subscriber B, a session closure signal. The receipt of the disconnection signal is the element triggering the generation and the transmission of the session closure signal. In  FIG. 8 , it is the DSLAM A  that generates and transmits to the DSLAM B  said session closure signal.   Step 12: When the Internet access provider of the subscriber A is informed of the disconnection of the modem-router MR′, it generates and transmits to the multiplexer MUX (R MUX , SR MUXA  or DSLAM MUXA ), a control signal in order to stop the multiplexing of the transmission line L A  of the subscriber A, so that only the numerical data associated with the connection parameters of the subscriber A pass through said line. The receipt of the session closure signal is the element triggering the generation and the transmission of the stop control signal. In  FIG. 8 , it is the DSLAM A  that generates and transmits said control signal. This Step 12 may be implemented before or after Step 11.       

     In response to the receipt of the session authorization signal (Step 8), the modem-router MR′ may generate and transmit a session electronic signature to the Internet access provider of the subscriber B and/or to the Internet access provider of the subscriber A, and more specifically to the DSLAM B  and/or to the DSLAM A . Said session electronic signature may notably include the following numerical data: unique identifier (for example, IMSI) of the subscriber B, date, time, IP address of the modem-router MR′. Said session electronic signature makes it possible to track the connection histories of the subscriber B when he uses the modem-router MR′ from the internal handler of the dwelling of the subscriber A. 
     In accordance with the invention, the terminating point P A  is likely to simultaneously receive the numerical data associated with the connection parameters of the subscriber B and the numerical data associated with the connection parameters of the subscriber A. 
       FIG. 9A  illustrates an embodiment where the telephone plug adapter P′ orients, towards the modem-router MR′, the numerical data “A” associated with the connection parameters of the subscriber A and the numerical data “B” associated with the connection parameters of the subscriber B. The telephone plug adapter P′ also orients towards to the native modem-router MR A  said data flow “A+B”. The modem-router MR′ therefore receives the data flow “A+B” and performs a demultiplexing in order to only process (demodulate) the data “B”. Similarly, the modem-router MR A  receives the same data flow “A+B” and performs a demultiplexing in order to only process (demodulate) the data “A”. 
       FIG. 9B  illustrates another embodiment where the native modem-router MR A  is not capable of performing a demultiplexing of the data flow “A+B”, only the modem-router MR′ having said capacity. In this case, the telephone plug adapter P′ diverts the data flow towards the modem-router MR′. Said latter performs a demultiplexing in order to process the data “B” and send back the data “A” towards the telephone plug adapter P′ which transmits same to the native modem-router MR A  for processing. 
       FIG. 10  illustrates an alternative embodiment where the modem-router MR′ comes to replace the native modem-router MR A . Therefore, it is the subscriber A that does the acquisition of the modem-router MR′. 
     By referring to  FIG. 11 , said modem-router MR′ comprises one or more processors or microprocessors  50 , one or more memories  51 , at least two network interfaces  52   A ,  52   B , which are mutually connected via a bus  53 . Said various components are already described previously in reference to  FIG. 4 . One or more computer applications—or computer programs—are saved in the memory or memories  51  and the instructions of which, when they are run by the processor or processors  50  make it possible to produce the functions described above in the description and notably the modulation, demodulation, multiplexing, demultiplexing of numerical data. 
     The network interface  52   A  is a wired or wireless communication interface adapted to establish a communication with the items of equipment E A  of the subscriber A, by using, for example, the private security key associated with the connection parameters of the subscriber A. And the network interface  52   B  is a wired or wireless communication interface adapted to establish a communication with the items of equipment E B  of the subscriber B, by using, for example, the private security key associated with the connection parameters of the subscriber B. Said network interfaces  52   A ,  52   B  are similar to the network interface  52  described previously in reference to  FIG. 4 . 
     In said embodiment, the modem-router MR′ further comprises a connection interface  54  for smart card, SIM card, or USB stick. Said connection interface  54  is thus adapted to receive a secure removable media device  540  wherein are saved numerical data. In practice, said numerical data contain the connection parameters of the subscriber B or at least identification data of the account of the subscriber B, and notably his subscriber unique identifier. The Internet access provider of the subscriber B may provide said latter with the secure removable media device  540  pre-parametrized. The subscriber B may also parametrize himself the media device  540 , prior to his installation in the dwelling of the subscriber A. The subscriber B thus simply needs to transport the secure removable media device  540 , the overall size of which is smaller than same of the modem-router MR′, said removable media device  540  being sufficient to recognize the subscriber B. 
     The modem-router MR′ here is parametrized beforehand with the connection parameters of the Internet network access account of the subscriber A and notably with the following numerical data: unique identifier of the subscriber A, identification data of the Internet access provider of the subscriber A, private security key, optionally certain rights and/or restrictions open to the subscriber A, etc. Said parametrization is performed as described previously. The subscriber A may, for example, use a computer or a Smartphone that he connects to the modem-router MR′. Said computer or said Smartphone acts as interface so that the subscriber A enters his connection parameters manually. The subscriber A connects in a wired (for example, with an Ethernet cable) or wireless (for example, by Wi-Fi) manner the modem-router MR′ to his native modem-router MR A . In response to said connection, or in response to the activation of a dedicated key installed on the box of the modem-router MR′, all of the connection parameters saved in the native modem-router MR A  are copied in the memory  51  of the modem-router MR′. The connection parameters may also be saved in a secure removable media device made available for the subscriber A. 
     The modem-router MR′ is connected directly to the internal handler of the dwelling of the subscriber A, in the same way as the native modem-router MR A . 
       FIG. 12  illustrates various steps implemented in the method subject matter of the invention, with the modem-router MR′ in  FIGS. 10 and 11 .
         Event 1: The modem-router MR′ is parametrized with the connection parameters of the Internet network access account of the subscriber A.   Step 2: Connection of the modem-router MR′ to the terminating point P A . This Step 2 may be implemented before or after Event EV1.   Event 20: The secure removable media device  540  is inserted into the connection interface  54 .   Step 3: The modem-router MR′ generates and transmits an authentication request to the Internet access provider of the subscriber A. The insertion of the secure removable media device  540  into the connection interface  54  is the element triggering the generation and the transmission of the authentication request. This step is identical to Step 3 described in reference to  FIG. 8 .   Step 4: The Internet access provider of the subscriber A generates and transmits to the Internet access provider of the subscriber B, a polling request. This step is identical to Step 4 described in reference to  FIG. 8 .   Step 5: The Internet access provider of the subscriber B verifies that said subscriber B is indeed affiliated therewith and, after verification, generates and transmits to the Internet access provider of the subscriber A an authorization signal. This step is identical to Step 5 described in reference to  FIG. 8 . Nevertheless, the authentication signal may further contain data relating to the connection parameters of the subscriber B, in the case where the secure removable media device  540  only contains the unique identifier of the subscriber B. The connection parameters of the subscriber B are in this case saved beforehand in an item of equipment (for example, a database) of the Internet access provider of the subscriber B.   Event 6: In response to the receipt of the authorization signal, the Internet access provider of the subscriber A opens the access rights to the subscriber B. This event is identical to Event 6 described in reference to  FIG. 8 .   Step 7: The Internet access provider of the subscriber A generates and transmits to the multiplexer MUX (R MUX , SR MUXA  or DSLAM MUXA ), a control signal in order to multiplex the transmission line L A  of the subscriber A. This step is identical to Step 7 described in reference to  FIG. 8 .   Step 8: The Internet access provider of the subscriber A generates and transmits to the modem-router MR′, a session authorization signal. This step is identical to Step 8 described in reference to  FIG. 8 . Said authorization signal may contain the data relating to the connection parameters of the subscriber B transmitted in Step 5.   Event 80: In response to the receipt of an authorization signal containing the data relating to the connection parameters of the subscriber B, the modem-router MR′ is automatically parametrized with the connection parameters of the Internet network access account of the subscriber B.   Step 9: The item or items of equipment E B  of the subscriber B can now connect to the modem-router MR′, via a wired or wireless connection and navigate on the Internet with the connection parameters of said subscriber B. Said connection is established via the interface  52   B  reserved for the subscriber B, with the private security key associated with the connection parameters of said subscriber B. Similarly, the subscriber A will be able to continue connecting his item or items of equipment E A  to the modem-router MR′, via a wired or wireless connection and navigate on the Internet with the connection parameters of said subscriber A. Said connection is established via the interface  52   A  reserved for the subscriber A, with the private security key associated with the connection parameters of said subscriber A. This step is identical to Step 9 described in reference to  FIG. 8 .   Step 10: When the secure removable media device  540  is withdrawn from the connection interface  54 , a disconnection signal is transmitted to the Internet access provider of the subscriber A. The withdrawal of the secure removable media device  540  is therefore the element triggering the generation and the transmission of the disconnection signal. The modem-router MR′ may, for example, emit said disconnection signal The generation and the transmission of the disconnection signal are identical to same described in reference to Step 10 in  FIG. 8 .   Step 11: When the Internet access provider of the subscriber A is informed of the disconnection of the modem-router MR′, it generates and transmits to the Internet access provider of the subscriber B, a session closure signal. This step is identical to Step 11 described in reference to  FIG. 8 .   Step 12: When the Internet access provider of the subscriber A is informed of the disconnection of the modem-router MR′, it generates and transmits to the multiplexer MUX (R MUX , SR MUXA  or DSLAM MUXA ), a control signal in order to stop the multiplexing of the transmission line L A  of the subscriber A. This step is identical to Step 12 described in reference to  FIG. 8 .       

     In reference to  FIG. 13 , the terminating point P A  is likely to simultaneously receive the numerical data “A” associated with the connection parameters of the subscriber A and the numerical data “B” associated with the connection parameters of the subscriber B. The modem-router MR′ therefore receives the data flow “A+B” and performs a demultiplexing of said flow. The data “A” travel via the network interface  52   A  and the data “B” travel via the network interface  52   B . The modem-router MR′ may therefore be used simultaneously by the subscribers A and B, same keeping their own Internet network access accounts and their own connection parameters. Of course, if the subscriber A does not connect any of his items of equipment E A  to the modem-router MR′, said latter will only be used by the item or items of equipment E B  of the subscriber B, and vice versa if the subscriber B does not connect any of his items of equipment E B  to the modem-router MR′. 
     The preceding description makes reference to subscribers A and B each having a different Internet access provider. Nevertheless, the invention also applies to the case where the subscribers A and B have the same Internet access provider. In this hypothesis, the DSLAM A  and DSLAM B  belong to said common provider and are generally located in MDFs that are distinct and remote from one another. 
     The arrangement of the various elements and/or means and/or steps of the invention, in the embodiments described hereinabove, must not be understood as requiring such an arrangement in all of the implementations. In any case, it will be understood that various modifications can be made to said elements and/or means and/or steps, without deviating from the spirit and scope of the invention.
