RU41946U1 - "INVISIBILITY" SYSTEM FOR THE PROVISION OF THE ANONYMOUS FORWARDING SERVICES OF INCOMING PHONE CALLS TO THE COMMUNICATION NETWORK ON THE BASIS OF PRE-PAYED CARDS - Google Patents

Abstract

The Invisible system refers to communication technology and can be used in systems for receiving and forwarding phone calls while maintaining the anonymity of the called subscriber, organized using prepaid calling cards. The system is distinguished by the use of an additional individual virtual telephone number of the user (IVTN), which is placed on a prepaid telephone card and for the processing of which a specially developed “Invisible” intelligent platform (IP) is used. The IP is connected to a dedicated telephone communication channel provided by the communication network operator and contains an administration unit (BA), a database (DB) and a switching unit (BC). The IP is responsible for the parameters of the call forwarding service for incoming calls and stores a table of allowed call forwarding numbers for each authorized user. To communicate with the user, the subscriber needs to know only the user's IVTN, by which the system finds the user by the forwarding numbers and connects the subscriber with it, keeping the real telephone number of the user secret. This service can be most demanded in all cases when the user wants to be available to a large number of different subscribers, but does not want to divulge their phone numbers, for example, when posting ads through the media.

Description

The proposal relates to communication technology and can be used in telephone communication systems, more precisely, in systems for receiving and forwarding phone calls while maintaining the anonymity of the called subscriber, organized using prepaid calling cards.

Currently, the use of prepaid cards for the provision of various communication services has received widespread application and widespread development. Most telecom operators offer various types of prepaid cards for outgoing international, long-distance and intra-city calls.

The prior art various proposals for the organization of systems for the provision of services using prepaid cards in the public telephone network, in the mobile communications network, Internet providers, IP-telephony operators.

The technical solution closest in the set of essential features was selected as “The system for providing access to paid resources in the communication network and the user's card with paid resources” according to the certificate of the Russian Federation at PM No. 22281.

The system includes:

user terminals associated with the telecommunications network, while users have individual identification numbers (IIN);

server or servers of network operators and providers;

server or servers of paid resources installed in the communication network. IIN is entered from user terminals, after recognition of which by the operator’s server, access to the paid resources server is performed. The system is characterized in that the server of telecom operators or providers includes a database and a billing center, while the identification tool is designed to receive information from the database with the specified number and to send a message to the user’s details and service code to the billing center for

providing warranty obligations on the payment of paid resources or writing off fees for paid resources from users' accounts of the public switched telephone network.

However, a significant drawback of both this and all other existing systems for the provision of communication services based on prepaid cards is the fact that they are used only for outgoing communication. those. only the cardholder directly, in other words, the user, can use the services provided by the card operator.

It is also known that some telecom operators provide a call forwarding service, but obtaining such a forwarding number is a long procedure associated with the execution of the contract, the allocation of a special forwarding number, etc.

The objective of this technical solution is to create a communication system that would allow the user not only to make outgoing calls, but also to receive incoming calls from any other subscriber.

In accordance with this task, the proposed technical solution allows the use of prepaid cards for incoming telephone communications while maintaining user anonymity, i.e. keeping secret the personal phone number of the card holder. In addition, the system provides access to the call forwarding service, with the ability to independently determine the user of various call forwarding parameters.

The goal is achieved by using an additional telephone number called an individual virtual telephone number of the user (IVTN), which is placed on a prepaid card and for processing which uses a specially developed intelligent platform (IP), called by the authors of "Invisible". The IP contains an administration unit (BA), a database (DB), and a switching unit (BC). The IP is responsible for the parameters of the call forwarding service for incoming calls and stores a table of allowed call forwarding numbers.

The system for the provision of anonymous call forwarding services for incoming phone calls to the communication network on the basis of prepaid cards, called by the author "Invisible" includes;

a switching system of a communication network operator providing a dedicated telephone communication channel, system user terminals and user calling terminals included in the switching system of a communication network operator; and a prepaid telephone card containing the serial number of the card and the personal identification number (PIN) of the card, covered with a special opaque strip.

The system has the following differences from known analogues.

The prepaid phone card additionally contains:

• individual virtual telephone number of the user (IVTN), designed to connect the subscriber with the user through anonymous forwarding,

• user service number, intended for access to management of anonymous forwarding service parameters, To the switching system of a communication network operator, through a dedicated telephone channel, a specially developed intelligent platform (IP) "Invisible" is included, designed to determine service parameters and establish a connection between the user terminal and the subscriber terminal.

The Invisible Intelligent Platform consists of the following blocks.

Administration block designed to manage the settings of the anonymous forwarding service by the user, namely:

• user authorization by PIN card,

• activation and deactivation by the user of the call forwarding service;

• user assignment of a table of allowed parameters of the forwarding service and its transfer to the database,

• user assignment of a table consisting of one or more telephone numbers of forwarding, their priorities, and its transfer to the database;

A database (DB) associated with the administration unit, containing a table of call forwarding service parameters, a table of sequences of call forwarding numbers generated for each authorized user,

and designed to select one of the forwarding numbers allowed by the user in accordance with the specified parameters of the forwarding service.

A database switching unit for:

• reception and processing of IVTN dialed by the subscriber,

• user identification by IVTN,

• determining the set parameters of the forwarding service and performing the procedure for selecting the allowed user forwarding number from the database,

• Establishing a connection with an authorized user redirection number,

• and, in the case of a user’s response, to establish a direct connection through the switching system of the communication network operator between the user and the subscriber, keeping the user's real telephone number secret.

• if there is no user response, to complete the procedure for selecting the next priority user forwarding number and a similar connection establishment,

• and if there is no user response to all the allowed forwarding numbers, to inform the subscriber about the impossibility of establishing a connection.

The system has the following additional differences.

A communications network is a public telephone network and / or a mobile communications network.

As permitted forwarding numbers, any PSTN phone numbers and / or mobile phone numbers can be indicated.

The parameters of the forwarding service are: the validity period of the forwarding service, the priorities and sequence of the forwarding numbers, the availability time of a specific forwarding number, the time to dial to a specific forwarding number,

the content of the response of the switch in the case of busy numbers forwarding, in the absence of a user response.

The following can be used as user and / or subscriber terminals: stationary telephones with the possibility of tone dialing, mobile telephones.

A standard PSTN telephone number in a given region can be used as the user's IVTN.

A combination of a standard telephone number of a PSTN in a given region and an extension number entered by a subscriber after a corresponding switch request in tone-dialing mode and consisting of N digits, where N varies from 2 to 15, can be used as a user's IVTN.

If an extension number is used as part of the IVTN, then after dialing the standard telephone number of the PSTN, the switch responds and requests to enter the additional number made by the subscriber from his terminal in tone dialing mode.

The user service number is intended for user access to the administration unit of the intelligent platform, and the same phone number is used as the user service number on all the system cards, which the switching system of the communication network operator transits through a dedicated communication channel to the IP.

The figure shows the connection diagram and the principle of the "Invisible" system.

IP "Invisible" is a software and hardware complex that can be implemented on the basis of an industrial computer system equipped with special voice and interface cards, for example, manufactured by Intel Dialogic, and control software designed for a specific circuit

connecting IP and taking into account the specific features of PSTN in a given region, the requirements of a communication network operator and the load that is to be serviced. The software performs two main functions: coordinating the work of virtual administration and switching units and creating and managing a database.

The user acquires a prepaid card of the operator of the communication network, which shows the serial number of the card, user service number, PIN card, user IVTN. Thus, the user automatically acquires a call forwarding number.

A user dials a “user service number” from his terminal. A call through the switching system of the communication network operator via a dedicated telephone channel is transferred for service to the administration unit of the IP "Invisible" (1, 3).

The administration unit of the IP “Invisible” activates the service: it requests a PIN card, identifies the user, sets all the parameters of the forwarding service, generates a table of forwarding numbers for this user, puts the table in the database (5),

The user must provide the system with at least one call forwarding number. This may be, for example, a PSTN phone number and / or a mobile phone network number.

All calls to this user’s name will be forwarded to the call forwarding number (s) in accordance with the forwarding table created by the user. Forwarding numbers can be ranked by priority, access time, and other parameters.

Any subscriber who calls the user should know his IVTN. From the subscriber’s terminal, a call through the switching system of the PSTN telecom operator is transferred to the switching unit of the Invisible IP (2, 4).

The user is determined by IVTN, its service parameters are determined from the database and the call forwarding number is found (6). After selecting the allowed forwarding number from the database, the switching unit makes an outgoing call, and after the user answers it connects it to the subscriber through the switching network of the PSTN telecom operator.

If there is no user response, the next priority forwarding number is processed in the same way. If the user does not answer on any of the forwarding numbers, the switching unit transmits to the subscriber a voice message about the impossibility of connection.

In any case, the subscriber knows only the user's IVTN, while the real user forwarding numbers remain unknown to him.

Such a service may be most demanded in all cases when the user wants to be available to a large number of subscribers, but does not want to divulge their phone numbers. A typical example of such a situation is the publication of an announcement in a newspaper or any other publicly available print or electronic media. In this case, the user in the ad indicates as his phone number the IVTN indicated on the prepaid card he purchased.

Thus, any subscriber at any time has the opportunity to freely contact the user through the Invisible system, and the user, for his part, remains in touch and remains incognito, i.e. there is mutual benefit.
