Description

The proposal relates to a communication network and can be used to increase regional and state security by accumulating information on the content of all conversations, facsimile messages and transmitted data by communication network subscribers for potentially all (100%) communication network subscribers.

The proposal uses the principles of packet information transmission in a communication network, which includes packet switching systems, for its implementation. The offer extends to those subscribers of the public switched telephone network (PSTN), built on the principle of switching channels, the route for establishing connections from (to) which (by which) passes through the mentioned packet switching systems.

Known methods for packet transmission of information in a communication network, in particular, disclosed in section 4.2 of the book by A. G. Zhdanov, D. L. Rasskazova, D. A. Smirnov, M. M. Shinikov "Voice transmission over packet-switched networks" ( IP-telephony) edited by V.Yu. Babkov and M.A. Voznyuk, St. Petersburg, 2001

There are also known methods of packet information disclosed in the monograph by M.A.Shneps-Shnepse "Internet Telephony: SIP Protocol and its Applications", "Max-Press", Moscow, 2002.

In these two sources of information describing known methods of packet transmission and selected as an analogue of the proposed method, operations of known methods for transmitting outgoing and receiving incoming packets of information (conversation, facsimile messages, data transmission) in a communication network, which includes systems packet switching.

Information sources are also known in which packet information transfer protocols are described (i.e., operations of the packet information transfer method). Such sources include an article by Larry Young, “New VoP Switching Protocol,” published in the journal Networks, No. 2, 2000, Open Systems Publishing House. This article focuses on the most promising SIP (Session Initialization Protocol). This article discloses the composition of information packages containing a set of fields that are different in their functional purpose (we also selected this article as an analogue).

From our point of view, it most fully describes the operations of transmitting outgoing information, the operations of receiving incoming information and discloses the composition of information packets (the contents of the fields of these packets) the well-known document "Network Working Group Request for Comments: 1889 Category Standards Track. Audio-Video Transport Working Group H. Schuizrinne GMD Fokus S. Casner Precept Software, Inc. R. Frederick Xerox Palo Alto Research Center V. Jacobson Lawrence Berkeley National Laboratory January 1996. RTP: A Transport Protocol for Real-Time Applications. (Comments on a number of International Network Working Group ", including on the issue of the real-time transport protocol RTP.)

The method of packet information described using the RTP protocols (RTCP and SIP) described in the indicated information source is selected as a prototype.

Note: for the sake of correctness, we note that the SIP protocol (with known method operations) is most fully implemented in the SAPFIR multiservice network node (the brochure is attached to this application).

So, the known method of packet data transmission, selected as a prototype, like the claimed method relates to a communication network, which includes packet switching systems with outgoing ports A and incoming ports B.

Outgoing ports A are connected to subscriber telephone installations or terminals of callers A.

Incoming ports B are connected to subscriber telephone installations or terminals of called subscribers B.

Note: of course, both ports A and ports B are bi-directional ports capable of serving both outgoing and incoming loads, but for the convenience of considering this application, we will, speaking about port A, imply that such a port only serves outgoing loads, and saying about port B, we will mean that the port only serves incoming load.

The known method is a prototype, like the claimed method, contains the following sequence of operations:

- the transmission of outgoing packets of information in the forward direction from the outgoing port A associated with the subscriber telephone installation or terminal of the subscriber A, to the incoming port B associated with the subscriber telephone installation or terminal of the subscriber B,

- or the transmission of outgoing information packets in the forward direction from the outgoing port A associated with the subscriber telephone installation or the terminal of the subscriber A, to the incoming port B associated with the subscriber telephone installation or the terminal of the subscriber B, and the transmission of incoming information packets in the opposite direction from the incoming port B associated with the subscriber telephone installation or the terminal of the subscriber B, to the outgoing port A associated with the subscriber telephone installation or the terminal of the subscriber B.

The condition for performing these operations of the known method, selected as a prototype, and of the proposed method is that each transmitted (and, accordingly, received) packet contains information:

- about the destination address,

- about the serial number of the package,

- about the time stamp,

- actually the information.

Note: i.e. that information, for the sake of which the whole garden is set up.

The main disadvantage of this method is the prototype packet information transfer is that this method:

- does not provide the accumulation of information on the content of all conversations, facsimile messages and transmitted data for potentially all (100%) subscribers of the communication network, as a result of which it does not provide an increase in regional and state security.

Naturally, the accumulation of this information is impossible for those subscribers of the public switched telephone network (PSTN), built on the principle of switching channels, the connection establishment route from (to) which (by which) passes through the mentioned packet switching systems.

In addition, since in the prototype method there is no accumulation of the indicated information, there is no question of the quality with which this information could be accumulated (with the quality of communication provided to subscribers or with a higher quality - see below).

The purpose of the proposed method is to increase regional and state security by accumulating information on the contents of all conversations, facsimile messages and transmitted data by communication network subscribers for potentially all (100%) communication network subscribers.

Another purpose of the proposed method is the accumulation of this information from PSTN subscribers when they establish outgoing connections, the route of which passes through packet switching systems.

Another goal (quite exotic and, at the same time, extremely important) is to improve the quality of the accumulated specified information in comparison with the quality of the initial information (with the quality of the information provided to subscribers).

Note: at the household level, we are accustomed to the fact that the quality of the recorded information cannot be higher than the quality of the original, as the speed cannot exceed the speed of light or the efficiency can be higher than 100%.

This increased quality of the accumulated information can significantly facilitate and increase the accuracy of some special procedures, such as, for example, voice identification.

The claimed method, as well as the known one, selected as a prototype, contains the operations and conditions for their implementation, given in the description of the method of the prototype.

Note: the known operations of the known method, coinciding with the operations of the proposed method, are implemented, in particular, in the application "Switching system" No. 2003116755 of June 03, 2003 for "Utility model", which received a positive decision FIPS. To simplify the description of the present proposal, the emphasis is not placed on the implementation of these known operations of the known method.

The above goals have been achieved, thanks to the cumulative introduction of operations, consisting in the fact that:

- at the same time or re-transmit from the side of the outgoing port A to the new, secondary destination address, each packet of information transmitted to the primary destination address from the outgoing port A to the incoming port B, and each packet of information transmitted to the primary destination address from the incoming port B to the outgoing Port A

- the specified transfer is carried out at a new, secondary destination address corresponding to the location of the database of packet switching systems and / or the database of the next (next) hierarchical (hierarchical) level (s), and / or the database, which is a centralized database (data warehouse ) a communication network or its fragment,

- when transferring packets to a new, secondary address, information about the serial number of the packet is stored in each outgoing and incoming packet and the information itself is saved;

- save at the same time in each outgoing packet timestamp information,

- save or correct the timestamp information in each incoming packet, taking into account the calendar time and the time the packet was sent in the forward direction from subscriber A to subscriber B and in the opposite direction and from subscriber B to subscriber A,

- replace, in this case, the information about the destination address of the outgoing and incoming packets with information about the aforementioned new secondary destination address,

- reduce, at the same time, the priority of transmission of outgoing and incoming packets to a new, secondary address compared to the priority of their transmission to the mentioned primary addresses,

- provide, at the same time, the transmission of information about the numbers of subscriber telephone installations or terminals of subscribers A and B when transmitting packets to a new, secondary address,

- they record in the mentioned (mentioned) database (databases) the content (more correctly, the content - authors' note) of all conversations of potentially all communication network subscribers and / or the data transmitted by them (including fax),

- additionally determine, when connecting the packet switching system to the subscriber search step of the electromechanical automatic telephone exchanges (PBX) during their modernization, the subscriber number A connected to the subscriber search step of the electromechanical automatic telephone exchanges in the process of establishing a connection to the outgoing port A of the packet switching system,

- carry out this determination of the number of the subscriber And using the equipment for determining the number (AON) of electromechanical exchanges.

The advantage of the proposed method of transmitting information in the communication network, provided by the totality of the features listed in paragraph 1, 2 of the formula, is that:

- an opportunity arises without any changes to the hardware of the existing communication network, which includes packet switching systems (including the latest modification of the SAPFIR system, the development of which is currently being completed, see the appendix, and in the algorithm whose work the above operations of the proposed method have already been implemented), organize a database (s) of data (decentralized and / or centralized data storage) to store the content (content) of all conversations of potentially all (100%) subscribers communication networks or data transmitted by them.

Notes:

1) The only hardware costs relate to the organization of the databases actually mentioned (data storage). This solution allows you to minimize the cost of organizing the recording of the content (content) of conversations of subscribers and the data transmitted by them and to provide the specified record for all 100% of the subscribers of the communication network, which creates the prerequisites for measures to improve regional and state security.

2) The function of recording the content (contents) of a conversation or transmitted data is not new in itself and over the past few years has been part of the functions of the "System of Organizational-Search Measures SORM" of any switching systems supplied to the telephone networks of the country. Moreover, the absence of the indicated functions of the switching system currently impedes or even impedes the introduction of such systems on the country's networks. In this application, in contrast to the SORM system, the operations of the method are described that allow you to implement these functions with minimal cost for potentially all (100%) subscribers.

- it becomes possible to take control, or rather, to record in the same database, the content of conversations and / or data from subscribers of electromechanical telephone exchanges PSTN, if the route of the established connection passes through the communication network and through packet switching systems,

- storing the specified data in a single repository allows you to make selections and sortings from the database not only by the number of subscribers included in the packet switching system of the communication network, but also by the number of subscribers included in the electromechanical ATS PSTN,

- the data storage period is determined by the characteristics of the databases, and with the current level of technology development it can be several years (10-20 years),

- the quality of the recording of the content (contents) of the conversation of subscribers A and B in the database can be significantly higher than the quality of the initial conversation of these subscribers. Improving the quality of recording is achieved by correcting the timestamp information of incoming packets. Indeed, when recording information in the database, all delays that occur when transmitting packets in the forward and backward directions (these delays may be due to insufficient bandwidth of the transmission channel, insufficient noise immunity of this channel, and a number of other factors) can be reduced to zero.

From all that has been said, it can be concluded that the proposed technical solution allows solving urgent issues of increasing regional and state security by using modern information technologies of communication networks, into the protocols of which, such as SIP, RTP, RTCP, the operations proposed in this application can be easily entered way. In this case, the hardware of the communication network switching systems is completely preserved. In this vein, the aforementioned SAPPHIRE system looks great.

Note: organizations responsible for ensuring the information security of the country will in every way support the introduction of systems with the functionality described in this application on the country's communication networks. The implementation on communication networks of systems that do not have the indicated functionality will be partially or completely limited. This idea has been repeatedly voiced in the 6 ^th All-Russian sectoral meeting "Safe operation of the communications industry - part of national security", held on 17-20 June 2003

Figure 1 shows an example of a communication network with packet switching systems in which the inventive method can be implemented.

This application is based on the materials of application No. 2003116755 of June 03, 2003 for a utility model. "Switching system", which describes the known process of switching information packets and in which the proposed method can also be implemented.

Note: a positive decision of FIPS was received for this application for a utility model.

The method according to claim 1 of the formula for packet transmission of information in a communication network is a set of sequentially the following operations, consisting in that:

- transmit outgoing packets of information in the forward direction from the outgoing port A associated with the subscriber telephone installation or the terminal of the subscriber A, to the incoming port B associated with the subscriber installation or the terminal of the subscriber B,

- or transmit outgoing packets of information in the forward direction from the outgoing port A associated with the subscriber telephone installation or terminal of the subscriber A, to the incoming port B associated with the subscriber telephone installation or terminal of the subscriber B,

and transmit incoming packets of information in the opposite direction, from the incoming port B associated with the subscriber telephone installation or terminal of the subscriber B, to the outgoing port A associated with the subscriber telephone installation or terminal of the subscriber B;

- information packets transmitted in the forward and reverse directions contain information:

- about the destination address,

- about the serial number of the package,

- about the time stamp,

- about the actual information, which is the information component of the package.

Notes:

1) Each package of information consists of fields, part of which contains the specified information, and the other part of which is not decisive for considering the essence of the proposal.

2) The composition of the information packets and the contents of these packets are not operations of the method. They should be considered as a condition for performing operations of the proposed method.

- At the same time (with the transmission of the information packet in the forward direction or the reception of the information packet transmitted in the opposite direction) or re-transmitted from the outgoing port A to the new, secondary address, each information packet transmitted at the primary destination address from the outgoing port A to the incoming port B , and each packet of information transmitted to the primary destination address from inbound port B to outbound port A,

- the specified transfer is carried out at a new, secondary destination address corresponding to the location of the database of packet switching systems and / or the database of the next (next) hierarchical (hierarchical) level (s), and / or the database, which is a centralized database (data warehouse ) a communication network or its fragment,

- when transferring packets to a new, secondary address, they save in each outgoing and incoming packet information about the serial number of the packet and save the actual information,

- save at the same time in each outgoing packet timestamp information,

- save or correct, in this case, timestamp information in each incoming packet, taking into account the calendar time and time of transmission of the packet in the forward direction from subscriber A to subscriber B and in the opposite direction from subscriber B to subscriber A,

- replace, in this case, the information about the destination address of the outgoing and incoming packets with information about the mentioned new destination address,

- reduce, at the same time, the priority of transmission of outgoing and incoming packets to a new, secondary address compared to the priority of their transmission to the mentioned primary addresses,

- provide, at the same time, the transmission of information about the numbers of subscriber telephone installations or terminals of subscribers A and B when transmitting packets to a new, secondary address,

- record (after receiving the specified packets transmitted to a new, secondary address) in the mentioned (mentioned) database (s) the content (content) of conversations of all subscribers of the communication network and / or the data transmitted by them (including fax).

Note: operations of subsequent sampling, sorting, archiving and other operations with data recorded in these databases are not considered in this application, because can be performed using well-known technical means of working with databases,

- additionally determine, when connecting the packet switching system to the subscriber search step of the electromechanical automatic telephone exchanges (PBX) during their modernization, the number of the subscriber A connected to the subscriber search step of the electromechanical automatic telephone exchanges in the process of establishing a connection to the outgoing port A of the channel switching system,

- carry out this determination of the number of the subscriber And using the equipment for determining the number (AON) of electromechanical exchanges.

Figure 1 shows a communication network 1, which includes information packet switching systems.

Figure 1 shows the terminal systems 2, 3 switching information packets associated with the data network 4 (or SIP network) circuits 5, 6, respectively. The data transmission network 4 (or SIP network) is connected to other packet switching information systems of the communication network 1 by chains 7, 8 (these other systems are not shown in FIG. 1).

Each of packet switching systems 2, 3 includes hardware and software, including 9 SG signaling gateway with Session Initialization Protocol 10 (SIP) or a modification of this protocol, 11 MG media gateway, and local computing switch 12 Networks (LAN) - Ethernet Switch. The software also includes the real-time protocol RTP and the real-time transport protocol RTCP (in Fig. 1, these protocols are not separately allocated, but are part of the SG signaling gateway 9 and the media gateway 11).

The signaling gateway 9 is connected by bus 13 to the switch 12 Ethernet Switch. The media gateway 11 is connected by a bus 14 to an Ethernet switch 12.

The signaling gateway 9 is connected by the control bus 15 to the media gateway 11.

The switch 12 is connected by a bus 16 to a router 17, which, in turn, is connected by a circuit 5 to a data transmission network 4 (or a SIP network).

The switch 12, in addition, is connected by a bus 18 with a storage device 19 (with a database).

Note: depending on the configuration of the communication network and the principles for solving the problem of ensuring regional and state security, the storage device 18 (database) for recording the contents (contents) of conversations and data of subscribers A and B may be part of the terminal packet switching system and / or the composition of the nodal packet switching system and / or the composition of a centralized data storage network of a communication network or its fragment (in Fig. 1, the nodal packet switching system and centralized storage are not shown; they are shown in figure 2).

From the foregoing, it follows that element 19 may not be included in packet switching systems 2, 3 if, for example, the configuration of the communication network is designed for the presence of a centralized data storage in the communication network. However, in figure 1 this element, for the convenience of description and its specification, is shown.

Switch 12 Ethernet switch is connected, in addition, via bus 20 to the module 21 forwarding (Proxy server), as well as via bus 22 with SIP-terminal 23 telephone and via bus 24 with SIP-terminal 25 computer.

Bus 22 is connected to port 26 A (B), and bus 24 is connected to port 27 A (B) of Ethernet switch 12.

Notes:

1) For convenience of description, we assume that, speaking of outgoing communication from calling subscriber A of terminal 23 or 24, the packet switching system has outgoing ports A 26 and 27. Speaking about incoming communication to calling subscriber B of another communication network switching system, this other the system has incoming ports B 26 and 27 connected to the terminals 23 and 25 of the called subscriber B. In reality, each of ports 26 and 27 is a bi-directional port through which both an outgoing connection and an incoming connection can be made.

2) Tires 13, 14, 16, 18, 20, 22, and 24 are bidirectional; information transfer can be arranged on them in the forward and reverse directions.

In Fig.1 elements with numbers 29 and 30 are absent. These rooms are reserved.

Figure 2 shows the communication network 1, which, as well as the network 1, shown in figure 1, includes packet switching systems.

Note: of course, the communication network 1 depicted in FIGS. 1 and 2 is the same communication network, but for the convenience of compiling a description of the application, it is depicted (as the same element 1) in two figures.

The difference between FIG. 2 and FIG. 1 is that, as packet switching systems, FIG. 2 does not depict terminal packet switching systems with subscriber telephone installations or terminals included in them, but a nodal packet switching system and a packet switching system in which a centralized repository (database) of the content (contents) of conversations of all subscribers of the communication network and / or the data transmitted by them (including fax messages) was organized.

For convenience of description, we will assume that figure 2 shows a data network 4 (or SIP network) connected by chains 7, 8 to network 4, shown in figure 1.

Note: if figures 1 and 2 were depicted on the same sheet, the need for chains 7 and 8 (in figure 1 and figure 2) would disappear by itself. Hence, chains 7 and 8 should be considered as additional, auxiliary or, if you like, virtual ones (from the point of view of understanding the essence of the proposal, these chains are of little use).

Again, for the convenience of description, we assume that the architecture of both terminal systems 2, 3 of packet switching (except for subscriber telephone installations and terminals), and the architecture of the node switching system 31, and the architecture of the switching system 32, in which centralized storage is organized, the database match completely. And from this coincidence, it follows that both system 26 and system 27 contain an SG signaling gateway 9 with SIP packet information protocol 10, an MG media gateway 11, and a local area network (LAN) switch 12 — an Ethernet switch.

The software also includes the real-time protocol RTP and the real-time transport protocol RTCP (these protocols are not separately allocated, but are included in the software of the SG 9 signaling gateway and 11 MG media gateway).

The packet switching systems 31 and 32 shown in FIG. 2 also include: a switch 12, a forwarding module 21 (Proxy Server), a storage device 19 — a database (though with the proviso that the presence / absence of element 19 in the specific packet switching system depends on the configuration of the regional or state security system). In addition, the composition of the switching systems 31 and 32, shown in figure 2, includes a router 17.

Tires 13, 14, 16, 18, 20, as well as circuits 5 and 6 of the switching systems 31 and 32, connect the same elements that these buses connect in FIG. 1, therefore, these connections are not disclosed in more detail so as not to clutter the description .

The packet switching system 31 is connected to the communication network 1 by a circuit 33, and the packet switching system 32 is connected to the communication network 1 by a circuit 34.

Chains 33 and 34 are identical to circuit 5 and 6 of FIG.

The materials of the application No. 2003116755/20 (018117) dated June 3, 2003, on which a positive decision of FIPS was received, are mentioned in this application. This application describes a switching system, most of the elements (and the connections between them) which coincides with the switching system that implements the inventive method. Mentioned switching system, as described in this application, can implement the inventive method (if it is equipped with - additionally - a storage device 19 on which the database can be implemented, and enter a number of operations of the inventive method).

Note: in the latest modification of the multi-service site "SAPFIR" and in the latest version of its software, the development of which is currently being completed, the operations of the proposed method are implemented in full.

In connection with the foregoing, in the framework of this application does not describe the known method of transmitting packet information (which is implemented and described in detail in application No. 2003116755/20 (018117)), but immediately makes the transition to additional transfer of information necessary for solving security problems.

It should be noted that the operations of the proposed method in accordance with paragraph 2 of the formula can be implemented exclusively using a switching system according to the application for the said "Utility Model". That is why, in the framework of the description of the system that implements the inventive method depicted in figure 1 and figure 2, elements for determining the number of the caller using the equipment for determining the number (AON) are not shown.

Note: from the aforesaid it follows that the switching system, as part of the application for the “Utility Model”, should be considered not as some auxiliary option for implementing the inventive method, but as an integral part of the system in which the inventive method can be implemented ( Naturally, with the reservations mentioned above).

So, we consider the basic principles of the system that implements the inventive method.

First, let us once again draw the attention of the examination to the fact that the SIP protocol and the real-time RTP / RTCP protocols play a key role in information packet switching systems, with their structure of the organization of the fields of packets of transmitted information (taking into account the functional purpose of these fields).

When considering the operation of a system that implements the inventive method, we dwell on two tasks:

- task 1 of transmitting information (data, facsimile messages) from subscriber A or its terminal installation, included in the packet switching terminal system 2 to subscriber B or its terminal installation, included in packet switching terminal system 3;

- task 2 of information transfer (conversation between two subscribers A and B included respectively in terminal systems 2 and 3 of packet switching).

Such a partition is due to the fact that, in problem 1, there is practically one-way transmission of information from subscriber A (its terminal installation) to subscriber B (its terminal installation).

In task 2, there is a two-way transmission of information between subscribers A and B (conversational dialogue between them), and the requirements for a given quality of recording information (the contents of the conversation in the databases and / or data storage) are more difficult to fulfill.

So, we do not consider the process of establishing a connection between subscribers A and B (or their terminal settings), because it is described in detail in Appendix 1.

One way or another, in the claimed method over the communication network 1:

- transmit outgoing packets of information in the forward direction from the outgoing port A associated with the subscriber telephone installation or the terminal of the subscriber A, to the incoming port B associated with the subscriber telephone installation or the terminal of the subscriber B (this is the above task 1);

- or transmit outgoing packets of information in the forward direction from the outgoing port A associated with the subscriber telephone installation or terminal of the subscriber A, to the incoming port B associated with the subscriber telephone installation or terminal of the subscriber B, and transmit the incoming packets of information in the opposite direction, from the incoming port B, associated with the subscriber telephone installation or terminal of subscriber B, to the outgoing port A associated with the subscriber telephone installation or terminal of subscriber B (this is task 2 above).

When a connection is established from the SIP terminal 25 of the PC of subscriber A of the packet switching system 2, the connection passes through the bus 24, port 27 A, Ethernet switch 12, and then is processed by the SG signaling gateway 9 with SIP protocol 10 and media gateway 11, which are connected with switch 12 buses 13 and 14, respectively.

Under the control of the signaling gateway 9 (which is connected via the control bus 15 to the media gateway 11), the connection passes through the router 17, circuit 5, data network 4 (or SIP network) and then goes through circuit 6 to switching system 3, where it passes on the indicated paths in the opposite direction (from router 17 of packet switching system 3 to SIP terminal 25 of subscriber B).

When establishing connections from the SIP terminal 23 of the telephone subscriber A of the packet switching system 2 to the SIP terminal 23 of the subscriber B of the packet switching system 3, the same elements and the connections between them are used as when the connection between the SIP terminals 25 is computer (this was discussed above). The only exception is that instead of bus 24 and port 27, bus 22 and port 26 are used.

Now consider the specifics of the proposed method.

First of all, attention should be paid to the structure of transmitted packets of information, which (structure) should be considered as a condition for performing operations of the proposed method.

Each packet of information contains several fields (more precisely, each packet is divided into several fields), the contents of some fields to consider the essence of the proposed method is decisive, and the contents of other fields to consider the essence of the proposed method does not have special significance.

The defining fields of the information package include fields containing information:

- about the destination address of the packet,

- about the serial number of the package,

- about the timestamp.

Note: as a rule, this timestamp is relative and is tied for the most part to the beginning of the connection from side A. and also to the beginning of this connection on side B,

- about the actual information, which is the information component of the package (the contents of speech and / or data).

To achieve the objectives of this technical solution, the following operations of the proposed method must be performed:

- simultaneously (with the transmission of the information packet in the forward direction from subscriber A to subscriber B or the reception of the information packet transmitted in the opposite direction from subscriber B to subscriber A) or retransmit from the outgoing port A to a new, secondary address, each information packet transmitted at the primary destination address from outbound port A to inbound port B, and each packet of information transmitted at the primary destination address from inbound port B to outbound port A.

A new, secondary address can be entered (configured) in the signaling gateway 9 or in the Proxy Server forwarding module 21.

In all cases, the transmission of these packets to a new, secondary address is controlled by the signaling gateway 9. The information component of the packet is taken from the media gateway 11,

- the specified transfer is carried out at a new, secondary address corresponding to the location of the database of packet switching systems and / or the database of the next (next) hierarchical (hierarchical) level (s), and / or the database, which is a centralized database (data storage) communication network or its fragment.

In the framework of packet switching systems 2, 3, such a database is a memory device 19 connected by a bus 18 to a switch 12. Obviously, under the control of a signaling gateway 9, information necessary to ensure regional or state security can be recorded in memory device 19. The information transmission path in this case is minimal (from the signal gateway 9 and the media gateway 11 via the Ethernet switch 12 via bus 18 to the storage device 19).

If the database is geographically located outside the packet switching terminal system 2, 3, the packet transmission path to the new, secondary address must go through the data transmission network 4 (or SIP network), for which router 17 is needed. In this case, the information from the signaling system the gateway 9 and the media gateway 11 passes through the Ethernet switch 12 and the router 17 through the circuit 5 to the network 4. The further way of the transmitted information is due only to a new, secondary address. The destination point is a storage device 19 (database, centralized storage of one of the systems (31, 32) of packet switching network 4),

- when transferring packets to a new, secondary address, information about the serial number of the packet is stored in each outgoing and incoming packet and the information itself is saved.

Note: in principle, it is possible (as a modification of this operation) to organize a new end-to-end numbering of outgoing and incoming packets when transmitting to a new, secondary address, but such a solution requires some complication of the algorithm of operation of the signaling gateway 9 and is not detailed in the framework of this application.

- Store timestamp information in each outgoing packet.

- Save or correct time stamp information in each incoming packet, taking into account the calendar time and the time the packet was sent in the forward direction from subscriber A to subscriber B and in the opposite direction from subscriber B to subscriber A.

This operation of the proposed method can significantly improve the quality of the conversation of subscribers A and B when recording the contents of this conversation in the storage device 19 in comparison with the quality of the conversation of these subscribers, which actually occurred when switching information packets by packet switching systems of the communication network.

The quality improvement is due to the fact that during correction in each incoming packet of information, timestamps can compensate for both the delay T1 for transmitting the packet in the forward direction and the delay for transmitting the packet T2 in the opposite direction, i.e. compensate for the total time T = T1 + T2.

The transition from the relative time of the time stamps of each packet to the calendar time contributes to a more convenient and algorithmically more optimal arrangement of packets of the forward and reverse directions (i.e., outgoing packets and incoming packets) for their more convenient playback from the storage device 19.

Note: in one of the old jokes after a telepathy lecture, the lecturer was asked the question: "You talked about how to transmit thoughts to a distance, and where to get them?" In this application, we consider the inverse problem - where to get the contents of conversations (or data) of two subscribers A and B of the communication network (potentially for all 100% of subscribers) and where to remember them (in which databases, in which repositories), however, the question is what to do with the filled data, how and by what algorithms to process it, what technical (and administrative) means should be used, is beyond the scope of this application and is not detailed. Obviously, using known means of working with databases, the necessary samples and sortings of this data can be obtained (by time, by subscriber number A, by subscriber number B, by day of the week, etc., etc.), and all necessary printouts of this data are also made.

- Replace (in the preparation of packages for writing to the storage device 19 "their" packet switching system or any other packet switching system of the communication network) information about the destination address of the outgoing and incoming packets with information about the new, secondary, destination address.

- At the same time, they reduce the priority of sending outgoing and incoming packets to a new, secondary address compared to the priority of their transmission to the mentioned primary addresses.

This priority change occurs under the control of the 9 SG signaling gateway.

- Ensure, at the same time, the transmission of information about the numbers of subscriber telephone installations or terminals of subscribers A and B when transmitting packets to a new, secondary address.

The source of information about the numbers of subscribers A and B is a signaling gateway 9.

The address of subscriber B is stored in the signaling gateway 9 in accordance with the number dialed by subscriber A during the entire connection (there is no need to request it from the communication network equipment). The address of subscriber A is formed in the signaling gateway 9 SG when an application for establishing an outgoing connection occurs.

- Then they record (after receiving the specified packets transmitted to a new, secondary address) the content (contents) of conversations of all subscribers of the communication network and / or the data transmitted by them (including facsimile) in the mentioned (mentioned) database (s); Recording takes place in the storage device 19 of one (or several) packet switching systems of the communication network.

Note: we repeat, operations of subsequent sampling, sorting, archiving, and other operations with data recorded in databases (element 19) are not considered in this application, because can be done using well-known technical means of working with databases.

- Additionally determine, if the packet switching system is connected to the subscriber search stage (see "Utility Model") of electromechanical automatic telephone exchanges during their modernization, the subscriber number A connected to the subscriber search stage of electromechanical automatic telephone exchanges in the process of establishing a connection to the outgoing port A of the channel switching system.

- Carry out the specified determination of the subscriber number A using the equipment for determining the number (AON) of electromechanical exchanges.

Note: these last two operations make it possible to memorize the content (contents) of the conversation of two subscribers or the data transmitted by them (potentially for all 100% of subscribers) that are included in PSTN analog PBXs, but whose establishment route passes through at least one of the packet switching systems. And this, in turn, significantly expands the number of subscribers that can be covered by the control considered above to solve security problems.

In conclusion, it should be emphasized once again that the claimed technical solution allows, within the framework of packet switching systems of a fixed communication network, to provide (practically without any complication of equipment, not counting the installation of storage devices - databases, storages - on one or several packet switching systems of a communication network ), accumulation of the content (content) of the conversation of two subscribers A and B of the communication network for all (100%) subscribers or data transmitted by these subscribers. The availability of such data makes it possible to ensure regional or state security and create the prerequisites for solving one of the most urgent tasks of the present.

Claims (1)

A method for recording all conversations of packet switching systems in a data warehouse, which includes packet switching systems with outgoing ports A and incoming ports B, comprising the operation of transmitting outgoing information packets in the forward direction from outgoing port A associated with a subscriber telephone installation or terminal of subscriber A , to the incoming port B associated with the subscriber telephone installation or terminal of the subscriber B, and incoming packets of information in the opposite direction from the incoming port B associated with the subscriber by a telephone installation or terminal of subscriber B, to outgoing port A, associated with a subscriber telephone installation or terminal of subscriber B, when each packet contains fields with information about the destination address, serial number of the packet, timestamp, calendar time, and actually transmitted information, moreover from the outgoing port A, each information packet transmitted to the primary destination address from the outgoing port A to the incoming port B, and each information packet transmitted to the primary destination address I from the incoming port B to the outgoing port A, transmit to the secondary destination address corresponding to the location of the data warehouse - the database of packet switching systems and / or the database of the next hierarchical level, and / or the database, which is the centralized database of the communication network or its fragment, and the contents of all conversations of all subscribers of the communication network are recorded in the mentioned database; when transmitting packets to the secondary address, information about the serial number of the packet is stored in each outgoing and incoming packet, with they preserve information and information about the calendar time, characterized in that in each incoming packet, the calendar time is adjusted for the transmission time of that outgoing packet, the answer to which is this incoming packet, while transmitting outgoing and incoming packets to the secondary address reduce the priority of their transmission in comparison with the priority of their transmission to the mentioned primary addresses.
