The essence of the proposal is to introduce content equipment into a packet switching system constructed in a certain way.

Description

The proposal relates to telecommunication technologies, on the basis of which it is proposed to implement distributed information centers - repositories of content (content).

As a prototype, the well-known switching system according to the patent of the Russian Federation for utility model RI) No. 32655 U1 7 Н 04 М 3/00 with a priority of 03.062003 was chosen.

A known packet switching system using the Session Initialization Proteol (SIP) information transfer protocol or a modification of this protocol contains, in accordance with the aforementioned prototype utility model patent No. 32655, a media gateway (MG) connected by a bi-directional control bus to a signaling gateway ( SG), an Ethernet switch, connected by an Ethernet bus 1 to the MG Media Gateway, and 2 Ethernet bus with an SG Signaling Gateway.

The known system - the prototype contains a SIP terminal telephone and / or SIP computer terminal, each of which is connected to the Ethernet switch Ethernet bus 3 Ethernet and / or 4 Ethernet bus, respectively. In addition, the well-known prototype system contains the first Internet router connected via Ethernet input / output to the Ethernet switch 5 and its output / input connected to the Internet, a public communication network gateway (SSOP) connected by its input / an output via Ethernet bus with an Ethernet switch, and its output / input with a public communications network, and also contains a redirection server - a Proxy Server connected to its input / output via Ethernet bus 7 with an Ethernet switch.

The main disadvantage of the known packet switching system, selected as a prototype, is the impossibility of organizing distributed information centers, which are repositories of content - content.

It should be noted that the development of such content repositories, i.e. content development, contributes to streamlining access to the essence - the content (content) of various fields of knowledge, social activities, trade, etc. and currently refers to the most popular areas of technology.

Note that by content we mean the content of sites or blocks of graphic or textual information with specific content. Obviously, this content (content) must be kept up to date by dynamically adding information (content), editing, managing the output forms of the content, as well as by removing or completely replacing the content. In addition, should

it will be possible to set criteria for sorting and selecting (selecting) content.

In addition, by content we mean any informationally significant content of the server, information complex - texts, graphics, multimedia. Content is organized as pages using hypertext markup. The essential parameters of the content are its volume, relevance and relevance.

The inventive packet switching system using the SIP transmission protocol contains, like the system selected as a prototype (see the aforementioned patent No. 32655 for a utility model), all of the above elements and the relationships between them (see page 1, paragraphs 3 and 4, descriptions ) These elements and the relationships between them are placed in the restrictive part of the formula. To quote this part of the formula: “A packet switching system using the Session Initialization Protocol (SIP) or a modification of this protocol, containing a media gateway (MG), a bi-directional control bus connected to a signaling gateway (SG), an Ethernet switch, connected by Ethernet bus 1 to the MG media gateway, and Ethernet bus 2 with the SG signaling gateway, a SIP terminal is a telephone and / or SIP terminal computer, each of which is connected to an Ethernet switch by Ethernet bus 3 and / or Ethernet bus 4, respectively as well as containing The first Internet router connected via Ethernet input / output to the Ethernet switch with Ethernet switch 5, and via the Internet via its input / output, a public communications gateway (MTSP) connected via Ethernet input / output via the Ethernet switch 6 to Ethernet switch switch, and with its output / input - with a public communication network, as well as a redirection server - Proxy Server, connected with its input / output via Ethernet bus 7 with an Ethernet switch "

The purpose of the proposed technical solution is to expand the functionality of the packet switching system, selected as a prototype by eliminating the above drawback - the inability to organize information centers, storage of content (content).

Achieving this goal was possible due to the fact that a second router was introduced into the packet switching system, connected via its Ethernet 8 input / output with an Ethernet switch, and its output / input - with a SIP network, and a content server with content system connected by its input / output via Ethernet bus 9 to an Ethernet switch.

It should be noted that by a content system we mean a set of software modules that allow you to dynamically add, edit, delete content, manage forms of content output, and also set criteria for sorting and selecting content.

It should also be noted that, for example, on a communication network in a rural area containing several packet switching systems using the SIP information transfer protocol, content providing information support for the entire district may not be organized on all packet switching systems, but only on one (or several) of them. This significantly reduces the cost required to organize content.

Thus, the claimed packet switching system eliminates the above drawback and achieve the above goals.

Figure 1 shows the structural diagram of the inventive packet switching system using the SIP information transfer protocol.

Figure 1 shows bidirectional Ethernet buses 1-9, connected, on the one hand, with an Ethernet switch 10, and on the other hand, with various elements of the packet switching system, which (elements) will be detailed below.

The packet switching system includes a media gateway (MG) 11 connected by a bi-directional control bus 12 with a signaling gateway (SG) 13 with SIP protocol. The Ethernet switch 10 is connected by an Ethernet bus 1 to a MG 11 media gateway, and an Ethernet bus 2 is connected to an SG signaling gateway 13.

In addition, the packet switching system includes a SIP telephone terminal (or a group of such terminals) and / or a computer SIP terminal (or a group of such terminals).

Figure 1 shows one SIP terminal 14 telephone and one SIP terminal 15 computer. A SIP terminal 14 telephone is connected to the switch 10. Ethernet switch bus 3 Ethernet, a SIP terminal 15 computer is connected to the switch 10 Ethernet switch bus 4 Ethernet.

The inventive packet switching system contains, in addition, the first router 16 of the Internet connected to its input / output 17 via Ethernet bus 5 with an Ethernet switch 10, and its output / input 18 to the Internet 19.

The public communication network 20 is connected to the gateway 21 of the public network. This gateway 21 has an input / output 22, through which it is connected via an Ethernet bus 6 to an Ethernet switch 10, and an output / input 23, through which it is connected to a public communication network 20.

The packet switching system also includes a forwarding server - Proxy Server 24, connected via its input / output 25 via the 7 Ethernet bus to the 10 Ethernet switch.

To achieve the above goals, a second router 26 has been introduced into the packet switching system using the SIP information transfer protocol, connected via its Ethernet input / output 27 via Ethernet bus 10 to Ethernet switch 10, and its output / input 28 to SIP network 29, and introduced a content server 30 with a content system 31, connected by its input / output 32 via the Ethernet bus 9 with the Ethernet switch 10.

Consider the operation of the proposed packet switching system depicted in figure 1.

The work of the proposed packet switching system when communicating its terminals 14 and 15 with the public communications network 20 and with the Internet 19 is similar to that in the prototype system.

Outgoing and incoming communication from terminals 14, 15 or to terminals 14, 15 is carried out, as in the prototype, through a packet switching system using NGN protocols (Sigtran, H.248, SIP) and speech compression technology (G.723.1) implemented in the media gateway 11.

Subscriber SIP terminals 14 and 15 can receive both outgoing and incoming communication through a router 16 to (from) the Internet network 19, and through a gateway 21 to (from) a public communication network 20.

In this case, the SIP and RTR protocols are used.

Consider the operation of the inventive packet switching system to achieve the above goals.

Access to the content server 30 with the content system 31 can be arranged:

- from SIP terminals 14.15 of “their own” packet switching system (that is, the packet switching system in which these SlP terminals 14, 15 are included);

- from any computer through the Internet 19 and the router 16 (the computer in figure 1 is not shown);

- from any computer through the public communication network 20 and the gateway 21 (the computer in figure 1 is not shown);

- from any SIP terminal of a telephone and / or SIP terminal computer through a SIP network 29 and a router 26 (these SIP terminals are not shown in FIG. 1).

The organization of the specified access to the content server 30 with the content system 31 is controlled by the SG signaling gateway 13 using the SIP protocol. If necessary, Proxy Server 24 can be used.
