Description

 The invention relates to radio engineering and computer technology and can be used to ensure the connection of personal computers to the Internet.

 Various currently known systems (WO 99/65192, H 04 L 12/28), (WO 9722211, H 04 Q 3/00), (WO 9722209, H 04 Q 3/00), (W09725798, H 04 L 9/00), (EP 0748095, H 04 L 29/06) do not have the ability to connect a consumer device, such as a personal computer to the Internet, at the choice of the consumer himself through various providers providing this type of service. To connect a consumer with one of the providers, he purchases a card to pay for the services of this provider and enters its data into his account in the database on the server of this provider. To connect a consumer to the Internet through another new provider, he is forced to buy a card of this provider in order to transfer money to a current account stored in the server database of another provider. Thus, the consumer is limited in the ability to connect to the network through the servers of various providers, which have equipment that is diverse in their technical potential, differing in the speed of information transfer, in workload at a specific consumer’s working time during the day, at different cost of the services provided to customers.

Standard Internet Connection System (Annabel Z. Dodd "The Essential Guide to Telecommunications", 2nd edition, Publisher: Prentice Hall PTR, Prentice-Hall, Inc., Upper Saddle River, NJ 07458, Second Edition July 26, 1999, 1384 pages), (Sam Halabi, Danny McPherson, "Internet Routing Architectures", Second Edition. Publisher: Cisco Press, USA, Second Edition August 23, 2000, 528 pages), (Robert Cowart, Brian Knittel, "Special Edition Using Microsoft Windows 2000 Professional, Publisher: Que, Printed in the United States of America, First Edition February 24, 2000, 1536 pages) includes the following:
Communication device (NAS: Network Access Server) - a device that transmits electrical signals over a telephone line and connects consumer devices that transmit alphanumeric information (personal computers, terminals and mini-machines) to the Internet. An example is CISCO 2611, CISCO 5300.

 Modem device - a device that connects consumer devices that transmit alphanumeric information (personal computers, terminals and mini-machines) with communication devices. It is a standard component. Examples are the 3COM 56K modem, Rockwell 33.6.

 Database - a system for processing large amounts of data in a structured form. It is a standard component. Example - ORACLE, MySQL, Postgress.

 Server (AAA server) - a computing device with software that processes applications for Internet access, extracts and writes information about Internet access to the database. It is a standard component. Structurally performed as an AAA module. Examples: FREE RADIUS, XT RADIUS.

 In the present invention, a communication device is also understood to mean the router included in its composition - a device that establishes a connection between communication devices of providers and the Internet. This device is connected in accordance with the characteristics of the switch of the communication device to the output of the communication device directly or is included in it, and its output is connected to the Internet. Standard component. Examples are CISCO 3640, CISCO 3660.

 In a standard system for connecting consumer devices to the Internet, the following data and data structures are used.

Static data
Data located in the server database and which can be modified using its software
Customer data
Consumer data (account - information necessary for the admission of the consumer device: computer or terminal to the Internet) is set when embedding (entering) the consumer in the system. They are stored in the database. They are processed by the AAA server using the SQL protocol. Consumer data are shown in table 1.

 Consumer Code - The original consumer code. This code is a service code and is not used when exchanging information with the provider's server.

 Consumer name — The consumer name in the database. This data is original for each consumer. Fill in when creating a customer account.

 Password - text encoded using the MD5 protocol. It is specified in ITU. Used in conjunction with a consumer name to access the Internet.

 The value of the initial amount to use is the initial value of the account. It is filled when creating an account. Reflects the initial (maximum) amount of money on the account.

 Current value - the current value of the account. When the account is fully spent - 0, then the consumer device is not allowed on the Internet.

 The end date of the account is the calendar date by which the consumer device can be allowed on the Internet.

 Administrative ban - reflects the administrative permission of the consumer device to access the Internet. If the administrative ban is “zero”, Internet access is not allowed.

 The data for using the service of the provider are shown in table 2.

Dynamic data
Data that is transferred from communication devices to provider servers using "communication protocols." Used communication protocols:
- RADIUS - Remote Access Dial Up Server (standard protocol described in ITU in RFC 2138)
- PPP - Point to Point Protocol (standard protocol described in ITU in RFC 1661)
- TCP / IP - Transmission Control Protocol / Internet Protocol (standard protocol described in ITU in RFC 1180)
- SQL - Structured Query Language (standard protocol described in ITU in RFC 822)
The server (AAA server) and the communication device (NAS) exchange information (RADIUS packet), which is a structure consisting of dynamic data. An exchange takes place each time an application is received for access and / or the beginning or end of Internet access. The exchange takes place on the basis of the PPP protocol, which is established between NASom and the AAA server when they are connected. Calculations and data processing are performed by the server.

 Dynamic data are shown in table 3.

 To connect a consumer device with a provider based on its server (AAA server, mainly a RADIUS server) used, usually by Internet providers, various modem devices are used that meet any of the standards V.32, V.32bis, V.34, V.90 . Communication can be via an analog telephone line or ISDN BRI digital standard.

To connect a consumer device (client) with a provider, the following data is required:
- telephone number,
- consumer name
- password.

 Authentication and authentication forwarding is provided by the provider. Authentication is the process of checking consumer data and creating permission to access or refusing to connect to the Internet. With the standard method of connecting a consumer device to the Internet, authentication is carried out by the Authentication, authorization and accounting (AAA) system of the provider. AAA is located on the server (computer) of the provider. The communication device communicates with the AAA server through the provider's local network using the TCP / IP protocol. Commonly used operating systems are Linux, Free BSD, or Windows NT Server or Windows 2000.

 The original consumer data of the consumer device is stored (stored) in the server database. The combination of username and password below is also referred to as an "account".

 On the AAA server there is a configuration file with the parameters described in it.

The AAA server sends a request to the database specified through the SQL language and reads the original original account information specified above. The extracted information is compared with that received from NAS-a and a confirmation (Auth ACK) is returned on the NAS if the following conditions are met simultaneously:
The consumer name matches the original, the password received from NAS-a matches the original, and the current account value is greater than zero.

 Otherwise, the server (AAA server) returns a failure message to the NAS using the TCP / IP protocol (Auth NACK).

 It is clear that in order to ensure that a consumer device can be connected to the Internet through several providers, the entire array of static and dynamic data must be stored so that service providers connecting consumers to the Internet can process this data in the usual way and connect their ordinary consumers (their consumer devices ) to the Internet.

 The problem solved by the invention is the provision of the possibility, at the request of the consumer, of connecting his consumer device to the Internet through any of the providers directly selected by him.

 The technical result that can be achieved by the implementation of the claimed method is the possibility of reducing the installation of the entire customer database on the provider's server, increasing the number of processed consumer devices to be connected by the provider to the Internet and simplifying the work of the provider.

 The technical result that can be achieved by the implementation of the claimed system is the expansion of the arsenal of technical means to ensure the connection to the Internet of various consumer devices through different providers without the support of additional telecommunication and Internet equipment.

To solve the problem with achieving a technical result, a method of connecting a consumer device to the Internet through more than one provider includes:
- receiving the signal from the consumer device to the Internet via the communication device of the provider using its communication device and creating a data exchange protocol between the consumer device and the communication device, processing the static and dynamic data of the consumer device by the server with identifying the special name of the consumer device in the dynamic data field, denoting the ability to connect a consumer device to the network through at least two providers ;
- if there is no special name in the dynamic data field, the server checks the conditions for connecting to the Internet of the consumer device, namely, the name and password of the consumer device match the current account value stored in the server’s static database, there is an administrative ban, and the network connection time interval is calculated, and if these conditions are positively met, the consumer device is connected using the server’s communication device with the In network it will fail, and if at least one of the indicated conditions is not fulfilled - disconnecting the server communication equipment from the consumer device;
- the introduction of a computing device in which they create databases of codes, names and addresses of many providers, and also create databases of special names of various consumer devices and their addresses;
- if there is a special name for the consumer device in the dynamic data field, transmitting static and dynamic data of the consumer device to the computing device using the server’s communication device, as well as transmitting static data about the code, name, address and price per hour of this provider, creating an exchange protocol between server communication device and computing device;
- receiving from the communication device of the server on the computing device the dynamic data of the consumer device and verifying compliance with additional conditions: the special name of the consumer device and its address stored in the database of the computing device, if these additional conditions do not meet, transfer of the prohibition data via the communication protocol through the communication device of the server to connect a consumer device to the Internet, upon receipt of which communication e server equipment stops communicating with the consumer device;
- if the special name of the consumer device and its address are stored in the database of the computing device, it extracts static and dynamic data about the consumer from the exchange protocol between the server’s communication device and the computing device and checks the conditions for connecting to the Internet with the data from the consumer device provider, namely matches the name and password of the consumer device with those stored in the static database of the server, the current value of the account, n there is an administrative prohibition, and if these conditions are positive, the computing device calculates the time interval for connecting to the network for this provider, taking into account price data for a given time for various providers, and through the communication protocol with the server through its communication device transmits data on the consumer’s connection devices to the Internet and the time interval for connecting to the network, and if at least one of the specified conditions is not met, data on non-connection of Tel device to the Internet;
- when receiving data from a computing device on the provider's server about connecting the consumer device to the Internet and the time interval for connecting to the network using the server’s communication device, the consumer device is connected to the Internet, and when receiving data about the consumer’s device not connecting to the Internet, the server’s communication equipment provider accordingly terminates communication with the consumer device.

There are additional options for implementing the method, in which it is advisable that:
- the special name of the consumer device was entered into the Proxy-State dynamic data field;
- static data about the code, name and address of this provider was entered in the Provider additional data field, which is supplied with data fields about the use of the service;
- the special name of the consumer device was made of the domain type in the form username @ companyname, where username is the original name of the consumer device, and companyname is the identifier of the computing device.

 To solve the problem with achieving a technical result, a system for connecting a consumer device to the Internet through more than one provider contains at least two servers for providers equipped with their own communication devices, respectively connected to the servers of the providers and designed to connect consumer devices to the Internet through modem devices, one of which is connected to the output of the consumer device, and the other the input of a communication device for each of the providers, a computing device that is capable of storing special names designed to allow communication through several providers and the addresses of such consumer devices, and which is configured to communicate with each of the servers of the providers through their communication devices, wherein the server of each of the providers is configured to transmit via communication devices to a computing device with static data about the code, name, address, hourly price of this provider and the special name of the consumer device, and the computing device is configured to check the special name of the consumer device, its address, match the name and password of the consumer device with the current server’s static database account values, the presence of an administrative ban, the calculation of the time interval for connecting to the network of a consumer device for each of the providers and transmission to each of rovayderov data of the connection time interval, together with data transmission on the connected or unconnected consumer device to the Internet.

 These advantages, as well as features of the present invention are illustrated by the best option for its implementation with reference to the accompanying figures.

 Since the proposed method is implemented when the system for connecting a consumer device to the Internet through more than one provider, the description of the proposed method is given in the description section of the claimed system.

 A system for connecting a consumer device to the Internet via more than one provider (Fig. 1) contains at least two servers 1 of providers 2 and 3 (The number of providers is essentially unlimited). The servers 1 are equipped with their own communication devices 4, respectively connected to the servers 1 of the providers 2 and 3. The communication devices 4 are designed to connect the consumer device 5 to the Internet via modem devices 6 and 7. One of the modem devices 6 is connected to the consumer device 5, and another modem device 7 - to the input of the communication device 4 for each of the providers 2 and 3. Computing device 8 is configured to store special names, p designed to enable the communication of the consumer device 5 through several providers 2 and 3, and the addresses of such consumer devices 5. The computing device 8 is also configured to communicate with each of the servers 1 of the providers 2 and 3 via communication devices of 4 providers 2 and 3 (Routers on Fig. 1 is not shown, are part of the communication devices 4). Server 1 of each of the providers 2 and 3 is configured to transmit static data about the code, name, address, price per hour of provider 2 or 3 by means of communication devices 4 to the computing device 8, and also to transmit the special name of the consumer device 5 to the computing device 8 The computing device 8 is configured to check the special name of the consumer device 5, its address, the name and password of the consumer device 5 matching with those stored in the static database server 1 of the current account value, the presence of an administrative ban and the calculation of the time interval for connecting to the network of the consumer device 5 for each of the providers 2 and / or 3. The computing device 8 is configured to transmit data to each of the providers 2 and / or 3 about the interval connection time in conjunction with the transmission of data about the connection or, accordingly, not connecting the consumer device 5 to the Internet. In addition, the computing device 8, if necessary, can be configured to check the addresses of the providers 2 and 3 themselves with those stored in the database of the computing device 8.

 The system works (Fig. 1) as follows.

 The consumer of the consumer device 5, having bought only one card of the company that owns the computing device 8 and paying its bill through any provider 2, 3, etc., data about which is stored in the database (DB) of the computing device 8, is then able to connect to the network Internet through any of the selected providers, which the well-known system for connecting the consumer to the Internet cannot provide (Fig. 2).

 For simplicity of explanation of the operation of the claimed system, we consider the operation algorithm of the existing equipment for connecting consumer devices to the Internet (Fig. 3).

 Modem device 6 (for brevity, specified in block 1 of Fig. 3 as modem 6) of consumer device 5 (of any computer equipment) dials the telephone number of modem 7 with communication device 4 (NAS) using a regular telephone network. For example, the city phone number of provider 2, which owns the NAS (345-23). Two devices establish a telephone connection.

 After establishing a telephone connection, the modem 6 and the NAS communication device 4 establish the PPP protocol between themselves as defined by the UTI specification describing the PPP standard (block 2, Fig. 3).

 The data from table 1 "Data about the consumer" (block 3, Fig. 3) is transmitted using the established PPP protocol from the consumer device 5 (PU) to the communication device 4 (NAS).

 Server 1 (AAA server), connected to the communication device 4 via the TCP / IP protocol, makes a request of the form "Select * from cards" using the SQL protocol (block 4).

 From table 1, located in the database "Consumer Data", all information is extracted and transmitted via the SQL protocol to server 1 (block 5, Fig. 3).

 Server 1 performs a binary comparison of the name and password received from the database with those received from communication device 4 (NAS-a). If they match, the process proceeds to block 7, if not, to block 12.

 Server 1 (block 7, Fig. 3) performs a logical check. The current amount is> 0. If yes, then execution goes to block 8, if not, then go to block 12 (Fig. 3).

 Server 1 performs a logical check "Administrative ban> 0" (block 8, Fig. 3). If this is true, go to block 9, if not true, go to block 12.

 Server 1 (block 9, Fig. 3) calculates the Session timeout field according to the formula Session Timeout = Current value / hour price, where the "current value" is retrieved from the database in block 5.

 Server 1 sends a RADIUS packet to the NAS, while the data field is state = 1, and session Timeout is taken as the value calculated in block 9 (block 10).

 A communication device 4 (NAS) establishes a TCP / IP connection between the consumer device 5 and the Internet (block 11, FIG. 3). The end of the process. Computer equipment gained access to the network.

 If at least one of the conditions in the logical blocks 6, 7, 8 is not satisfied, then server 1 sends a RADIUS packet to the NAS, with the field state = 0, i.e. access to the Internet is prohibited (block 12). The NAS terminates the telephone connection between the communication device 4 and the consumer device 5 (PU). The end of the process. Access to computer equipment on the Internet is denied.

Disconnection of PU 5 from the Internet may occur due to the following reasons (Fig. 4):
- interruption of telephone communications due to interference on the line or insufficient quality;
- shutdown by the consumer from PU 5;
- disconnection from the provider (NAS-ohm) due to the end of the paid time spent on the network (session timeout).

 Due to the poor quality of the telephone line, the connection between the modem device 6 and the modem device 7 was interrupted (block 1, Fig. 4), respectively, there is a disconnection between the modem 7 and the communication device 4 (NAS-ohm).

 Communication may be interrupted by PU 5 (computer equipment) at the request of its consumer (consumer exit from the Internet). The reason for such a shutdown may also be problems with the software or hardware hardware of the computer (block 2).

 Communication is interrupted by server 1 (block 3) from the side of communication device 4 (NAS-a) due to the end of the consumer access time interval recorded in the parameter - session timeout.

 In any of the above cases, the communication device 4 (NAS) sends a RADIUS packet to server 1 with Acct-Status-Type = 1 and the corresponding session data (block 4). Session - a single connection of a consumer to the Internet, use of the service and termination of communication.

 Server 1 enters the packet (block 5) received from the communication device 4 (NAS-a) using the SQL language into table 2 “Data on the used service”. Server 1 (AAA server) calculates the amount by which the previous Current value decreases by the formula: Current value * = Current value - Price / Acct-Session-Time (block 6). Where Current value * is the balance on the account of consumer device 5 after connecting to the Internet, Current value is the amount of funds in the account in the server database for consumer device 5 at the start of the Internet connection session, Price / Acct-Session-Time is the cost connection services by provider 2 for a given time divided by the time interval for connecting the PU 5 to the Internet. Data on the new current value (Current value *) for this consumer device 5 is stored in the server database 1.

 The claimed system (Fig. 1) of consumer access to the Internet through a variety of providers (Multiple Provider Internet Access System - MPIAS) allows you to save the ability to connect to the Internet consumers of various providers with their credit cards, and at the same time provides access to the Internet for consumers by various providers (for example, having entered into an appropriate agreement with a company introducing computing device 8 into business operations - the owner of credit cards issued for communicating PU 5 through various providers). Computing device 8 can be structurally executed on the basis of produced AAA modules (FREE RADIUS, XT RADIUS), which, however, are modified to solve a new problem with the previous ones (which they previously performed to connect through one provider) and completely new functions (for connecting through several providers).

 An example of a specific implementation of the claimed system (Fig. 1) —Multiple Provider Internet Access System (MPIAS).

 The components of the technical solution for the implementation of the claimed system (Fig. 1) for provider 2 or 3 with respect to consumers using the connection service through several providers are the same, but with the following exceptions.

 The database for consumers connecting to the Internet through several providers does not exist as a component for servers 1 and, accordingly, is not used in the claimed shadow solution. Accordingly, providers 2 and 3 do not use static data on consumer devices 5.

 Dynamic data is the same as with the standard solution. A RADIUS packet with the same structure, but with one exception. The presence in the dynamic data field of the special name of the consumer device, indicating the ability to connect the consumer device to the network through at least two providers, shows that dynamic data is not processed by provider 2 or 3, but only redirected from it to computing device 8. To create Such special names can be used in various fields not used in Table 3, in particular, it is advisable to use the Proxy-State field (Table 3). In the standard solution, this dynamic data field exists, but is not applied. The special name can take a different form (username - XX @ YY), which is capable of being processed by server 1, communication device 4, and computing device 8. For the convenience of redirecting it from server 1 through communication device 4 to computing device 8, the special name of consumer device 5 domain type can be performed in the form username @ companyname, where username is the original name of the consumer device 5, which has the ability to access the Internet through several providers 2 or 3, and companyname is the identification Op computing device 8.

 The operation algorithm of provider 2 or 3 for the claimed technical solution is shown in FIG. 5.

 Modem device 6 (Fig. 1) PU 5 (computer equipment) transmits the dialed telephone number through modem device 7 (for brevity, indicated by the term "modem" in the diagram) to communication device 4 (NAS) via the telephone network. For example, the city phone number of provider 2, which owns the NAS (345-23). These devices establish a telephone connection between themselves (block 1, Fig. 5).

 After establishing a telephone connection, the modem device 7 and the NAS establish the PPP protocol between themselves as defined by the UTI specification describing the PPP standard (block 2).

 The data from table 1 "Consumer data" is transmitted using the established PPP protocol (block 3, Fig. 5) from the PU 5 to the communication device 4 (NAS).

 As can be seen from the diagrams (Fig. 3 and Fig. 5), the operation of server 1 (AAA server) at the initial stage does not undergo any changes.

 Further, in accordance with logical block 4, server 1 checks whether the dynamic field username contains data of the form XX @ YY. If yes, then go to block 5, if no, go to block 11. Block 11 is a standard connection. Next, after block 11, there is a connection to block 4 shown in FIG. 3. Processing is the same as in the case when the received data on the Internet connection comes from a consumer device 5, the owner of which has a credit card, for example provider 2, if the consumer device 5 connects to the Internet through provider 2.

 If there is a special name in the dynamic data field, then server 1 connected to the NAS via a TCP / IP puncture sends a RADIUS packet to computing device 8 (WU) containing data received from communication device 4 (block 5).

 VU 8 returns a RADIUS packet over TCP / IP to server 1, while the State field of the packet can be 1 or 0, depending on whether VU 8 allows or not to allow consumer device 5 to the Internet (block 6).

 Then server 1 (block 7) performs a logical check of the State field received with the RADIUS packet from computing device 8. If the field State = 1, then go to block 8, if not, to block 10.

 With the State = 1 field (block 8), server 1 transmits a RADIUS packet to the communication device 4 (NAS) with the session timeout value calculated in block 11 (Fig. 7).

 Communication device 4 (NAS) establishes a TCP / IP connection between the PU 5 and the Internet. The end of the process. Computer equipment gained access (block 9).

 With the field State = 0, server 1 transmits a RADIUS packet to the NAS with this label “0” in the dynamic field and prohibits the connection of consumer device 5 to the Internet (block 10).

 Communication device 4 (NAS) interrupts the telephone connection between the modem device 7 and the modem device 6 of the control panel 5. End of the process. Access to the Internet to the computer equipment of PU 5 was denied.

 From a comparison of FIG. Figures 3 and 5 show that the installation and processing of data by server 1 is greatly simplified.

 Due to the same reasons described above, the PU 5 may disconnect from the Internet (Fig. 6). As can be seen from FIG. 6, server 1, when consumer device 5 is operating in the mode of selecting one of the providers, only forwards the RADIUS packet with session data to WU 8.

 The operation of computing device 8 (Fig. 7) is similar to an AAA server (AAA module).

The components that are used are the same as with the standard solution (Fig. 2), with some exceptions:
Communication device 4 from the side of VU 8 - communication communications are carried out by the provider 2 or 3 and because of this, this equipment is not required.

 Modem device from the side of VU 8 - telephone communications are carried out by the provider 2 or 3, and because of this, this component is not needed.

 Router - connection to the Internet is provided by provider 2 or 3 and therefore this component is not needed.

 Static data about the consumer (account) is set when the consumer enters (fits into) the system. They are stored in the database of VU 8. Processed VU 8 (AAA module) using the SQL protocol. Consumer data is the same as with the standard solution.

Data on the use of the service is the same as with the standard solution, but with the following difference:
When using WU 8, a new Provider ID field was added, in which information about the provider through which the session was held is recorded.

Provider ID - Number - Integer
Provider data is original for the claimed system. They do not exist and are not used in the standard solution for connecting consumer devices 5 to the Internet. They are stored in the VU 8 database. They are processed by the modified AAA VU 8 module using the SQL protocol.

 The data are summarized in table 4.

 ProviderID - contains the original provider code. Used by the modified AAA module VU 8 to record in the table about the use of the service.

 ProviderName is the name of the provider. The name of the company that provided the service for connecting the consumer device 5 is recorded.

 ProviderIP - IP Address Provider. (IP address is the address of the communication or computer device of the provider. It is orginal. It is described in accordance with the specification for TCP / IP). The address of the communication equipment of provider 2 or 3 is indicated, from which dynamic data will be received. Used by AAA module VU 8. Processed through the SQL protocol. Data on providers and their prices are always entered into the WU 8 database in advance and change in the database as they change by the provider. When sending data about the consumer is not transmitted.

 Price data includes information on prices per hour of the provided Internet connection services of various providers. They are transmitted directly by providers 2 or 3 when they are connected to WU 8 or entered in advance into WU 8 when concluding agreements with various providers. They are stored in the WU 8 database and retrieved from it using the SQL protocol. Price data are summarized in table 5.

 For the dynamic data in the claimed system, a standard RADIUS package is used, described earlier in the section “Standard connection scheme of a consumer device 5 with the Internet”, but some of the dynamic fields are used for a different purpose.

 NAS-IP-Address - the IP Address of the NAS-a of provider 2 and / or 3 is indicated. Upon receiving it AAA, the VU 8 module writes it in the static "Service Usage Data".

 Proxy-State - this field is not used in the standard technical solution, but in the claimed system the corresponding code in it carries information that the consumer data is not processed by the server 1 of providers 2 or 3, but only transmitted to computing device 8.

 Works WU 8 in accordance with the following algorithm (Fig. 7).

 Server 1 of provider 2 or 3 submits an application through a RADIUS packet to WU 8 using the TCP / IP protocol (block 1).

 In WU 8, the protocol is accepted by the component - AAA module through the TCP / IP protocol (block 2).

 WU 8 (block 3), using the SQL protocol, extracts data from the database (table 4) for the corresponding provider 2 or 3, or some other not shown in FIG. 1.

 WU 8 checks (logical block 4) whether the IP Address received with the RADIUS packet matches the data received from the base of WU 8. If yes, go to block 5, if no, go to block 12 (Fig. 7) .

 WU 8 (block 5) retrieves consumer data (account) from its database.

 Then VU 8 performs a logical check (block 6), whether the name and password received from the RADIUS packet from provider 2 or 3 match those stored in the database of computing device 8. If yes, go to block 7. If no, go to block 12.

 WU 8 in block 7 performs a logical check: is the value of the "Current Amount" data field greater than zero? If yes, go to block 8, if no, go to block 12.

 Then VU 8 (block 8) performs a logical check: is the value of the "Administrative prohibition" field greater than zero? If yes, proceeds to block 9, if not, to block 12.

 Then WU 8 (block 9) extracts “Prices” from the database (from table 5), the price data of a particular provider, whose IP Address is obtained from the RADIUS packet in block 1.

 WU 8 (block 10) for this particular provider 2 or 3 calculates the Session Timeout dynamic data field using the formula. Session Timeout = Current Amount / Price. The session time interval is determined.

 VU 8 sends to the server 1 of the identified provider 2 or 3 RADIUS packet (block 11), filled with the following data: State = 1; Session timeout - as calculated in block 10.

 If any of the logical conditions in blocks 4, 6, 7, 8 is not satisfied, VU 8 sends to the server 1 through its communication device 4 the corresponding provider 2 or 3 RADIUS packet filled with the following data: State = 0. In accordance with the blocks 10 and 11 in FIG. 5, the provider does not connect the consumer device 5 to the Internet.

 Disconnection from the Internet is carried out in accordance with the circuit of FIG. 8.

 When connecting a consumer through the claimed system with the Internet, the following two procedures can be used.

 The first procedure of the provider 2 or 3 when connecting the PU 5 to the Internet from block 1 to block 4, and then to block 11 (Fig. 5), when the consumer has a credit card and a current account of this provider.

 The procedure for the provider 2 or 3 when connecting the PU 5 to the Internet through VU 8 from block 1 to block 9, when the consumer has a common credit card and a current account of the company serving the VU 8.

 The consumer, choosing one of the providers 2 or 3 (Fig. 1), dials his phone number and enters his name and password for access. If for some reason he is not satisfied with the access to the Internet (poor connection, communication, or low access speed), then he can stop his PU 5 (computer) from working with this provider. Having a current account in the VU 8 database and choosing another provider, it quickly connects to the Internet again, changing only the phone number to the number of the new provider. Therefore, the user of the VU 8 card has the ability to alternately connect his consumer device to the Internet through more than one provider.

Thus, the claimed system (Fig. 1) works by performing the following operations:
- receiving the signal from the consumer device to the Internet via the communication device of the provider using its communication device and creating a data exchange protocol between the consumer device and the communication device, processing the static and dynamic data of the consumer device by the server with identifying the special name of the consumer device in the dynamic data field, denoting the ability to connect a consumer device to the network through at least two providers ;
- if there is no special name in the dynamic data field, the server checks the conditions for connecting to the Internet of the consumer device, namely: the name and password of the consumer device match the current account value stored in the server’s static database, there is an administrative ban, and the calculation of the network connection time interval , and with the positive fulfillment of the indicated conditions, the connection of the consumer device using the server’s communication device with the AND network ternet, and when even any one of these conditions - to disable the media server hardware from the consumer device,
- the introduction of a computing device in which they create databases of codes, names and addresses of many providers, and also create databases of special names of various consumer devices and their addresses;
- if there is a special name of the consumer device in the dynamic data field, transmitting static and dynamic data of the consumer device to the computing device using the server’s communication device, as well as transmitting static data about the code, name, address and price per hour of this provider, creating an exchange protocol between server communication device and computing device;
- receiving from the communication device of the server on the computing device the dynamic data of the consumer device and verifying the compliance with additional conditions: the special name of the consumer device and its address stored in the database of the computing device, if these additional conditions do not meet, transfer of the prohibition data via the exchange protocol through the communication device of the server to connect a consumer device to the Internet, upon receipt of which communication borudovaniya server stops communicating with the consumer device;
- if the special name of the consumer device and its address are stored in the database of the computing device, it extracts static and dynamic data about the consumer from the exchange protocol between the server’s communication device and the computing device and checks the conditions for connecting to the Internet with the data from the consumer device provider, namely matches the name and password of the consumer device with those stored in the static database of the server, the current value of the account, n there is an administrative prohibition, and if these conditions are positive, the computing device calculates the time interval for connecting to the network for this provider, taking into account price data for a given time for various providers, and through the communication protocol with the server through its communication device transmits data on the consumer’s connection devices to the Internet and the time interval for connecting to the network, and if at least one of the specified conditions is not met, data on non-connection of Tel device to the Internet;
- when receiving data from a computing device on the provider's server about connecting the consumer device to the Internet and the time interval for connecting to the network using the server’s communication device, the consumer device is connected to the Internet, and when receiving data about the consumer’s device not connecting to the Internet, the server’s communication equipment provider accordingly terminates communication with the consumer device.

 The claimed method and system for connecting a consumer device 5 to the Internet via more than one provider has the following advantages.

Consumer Benefits
Using access to the Internet through the claimed system, consumers can:
- reduce their own costs associated with gaining access to the Internet, choosing the optimal provider;
- optimize the use of the service by choosing a provider with a higher-speed (maybe even more expensive) Internet connection to obtain large amounts of data or cheaper (but possibly low-speed) when performing unimportant tasks;
- use the services of another provider, when the one previously used by the consumer, in the process of work began to arise technical problems.

Benefits for the Provider
Providers can get more consumers and at the same time avoid the need to install the entire component database.

 The work of the provider is simplified, since he does not have to deal with and be responsible for the names, passwords and collecting money from small clients.

Benefits for the owner of computing device 8 (modified AAA server)
The owner of VU 8 can launch his own service extremely quickly without installing and maintaining telecommunication and Internet equipment, such as modems, NASs, routers. Avoids interaction with telecom and it does not need personnel for communication support.

 Specialists understand that the technical solution presented does not exhaust completely different options for its specific constructive implementation. However, this technical solution within the framework of the stated volume of patent claims allows us to solve the problem and improve the quality of the connection of various consumer devices to the Internet.

 Thus, the claimed method and system for its implementation is most successfully industrially applicable for working in networks with large numbers of consumer devices and with various technical capabilities of providers, mainly for working on the Internet.
