Description

The utility model relates to the field of communication, namely to data transmission networks, and can be used for the exchange of electronic information between subscribers and regional objects.

There are networks organized on the basis of wired communication lines and wireless technologies. Known WiMAX network (Worldwide Interoperability for Microwave Access), which is designed to provide broadband wireless Internet access, and also provides data exchange between local networks based on the IP protocol. The basic model of a WiMAX network [1] in accordance with the standard [2] is shown in Figure 1 and includes three main elements: a plurality of subscriber stations 1 (Fig. 1), a set of access networks 4 (Fig. 1) and a set of connection networks 5 (Fig. .1), where 7 (Fig. 1) are data streams and 8 (Fig. 1) are control flows.

Access network 4 (FIG. 1) is a plurality of IEEE 802.16 wireless access base stations 2 (FIG. 1) and gateways 3 (FIG. 1) for communication with a global or local IP network 6 (FIG. 1). Gateway 3 (Figure 1) connects the base stations of one access network with other access networks 4 (Figure 1) and with a connection network 5 (Figure 1).

Connection network 5 (FIG. 1) is a WiMAX operator network, it implements authorization, authentication and access control (AAA) functions, connects WiMAX subscribers to global or local IP networks 6 (FIG. 1), and provides services such as IP-telephony, access to public telephone networks, Internet access and private networks.

A disadvantage of the known model is the need to combine base stations over the air and provide direct visibility between WiMAX base stations, which leads to the need to install multiple base stations to ensure high-quality information exchange, as well as to overloaded wireless communication channels. This model provides access to the Internet, which significantly reduces the ability to protect information from unauthorized access when working in private networks.

The objective of the utility model is to create a secure computer network in the region to ensure the exchange of information between private networks of objects and subscribers of the region.

This task is achieved due to the fact that the network consists of fixed-access subscriber stations with an external directional antenna, wireless data channels and geographically spaced base stations of the WiMAX radio network, coupled through gateways and an interface with multiplexers of a fiber-optic communication line that combines base stations and an information and computing center, equipped with at least one central server, into a single network, and local networks, as well as a database server and regulatory reference information of regional objects can be connected both to wired data transmission channels of the main network and to wireless data transmission channels of the WiMAX radio network.

The technical result is to increase the productivity of the exchange of electronic information, for the operational interaction of state and private organizations, departments, representative offices, enterprises, as well as citizens of the region, providing access to databases and reference information for various purposes by working in a single information and computing network.

The network device is illustrated in figure 2, which depicts a model of a regional information computer network (RIVS).

The list of positions:

1. Subscriber stations of fixed access.

15. Local area networks of fixed subscribers.

16. Server database and reference information.

20. Information and computing center.

19. The central server of the computer center.

12. Wired data channels (fiber optic communication lines).

10. Multiplexers.

3. Gateways and interaction interface.

2. Base stations of a radio network.

11. Wireless data channels.

17. The main network.

18. The radio network.

21. Regional IVS.

RIVS operation is based on the use of the TCP / IP communication protocol family, which includes the following protocols: transport protocols, routing protocols, network address support protocols, application protocols, and gateway protocols. It matters that in order to protect information from unauthorized access to the network, there is no Internet access, connection of unregistered users, and also additional cryptographic means of information protection can be included in the subscriber equipment.

The RIVS model (Figure 2) includes the following main elements:

1. The main network 17 (Figure 2) - a wired data network organized on the basis of fiber optic communication lines (FOCL).

2. Wireless broadband access network based on fixed WiMAX technology (hereinafter WiMAX radio network) 18 (Figure 2).

3. Gateways and interaction interface 3 (Figure 2) - provide technical integration of the main network 17 (Figure 2) and the WiMAX 18 radio network (Figure 2) into a single regional information and computer network 21 (Figure 2).

The main network 17 (Figure 2) - the main "circuit" that makes up the backbone of the RIVS, is implemented on the basis of FOCL. It consists of the following main elements: wired data channels 12 (Figure 2); information and computer center 20 (Figure 2), equipped with at least one central server 19 (Figure 2); database server and reference information 16 (Figure 2), as well as local area networks 15 (Figure 2) connected to wired data channels 12 (Figure 2); fixed subscribers 1 (FIG. 2) having access to the network both via wired data channels 12 (FIG. 2) and wireless data channels 11 (FIG. 2). The network topology is organized according to the “everyone with everyone” type; it allows transmitting information in the shortest or least loaded directions. Multiplexers 10 (FIG. 2) are an access point to the core network 17 (FIG. 2) for base stations 2 (FIG. 2) of the WiMAX 18 radio network (FIG. 2) through an individual gateway for each base station 2 (FIG. 2) and interaction interface 3 (Figure 2). It provides data transfer, video, IP-telephony, access to databases, regulatory and reference information, electronic document management system. Information and computing center 20 (Figure 2) provides the functioning of the network and is a central control node, it includes at least one central server 19 (Figure 2). This center provides functions for delimiting and providing subscribers with access rights to the network.

The WiMAX 18 radio network (Figure 2) implements authorization and authentication management functions, provides wireless access to WiMAX 1 subscriber stations (Figure 2) to the main network 17 (Figure 2) throughout the region. It consists of: subscriber stations of fixed access 1 (Figure 2), equipped with an external directional antenna; wireless data transmission channels 11 (Figure 2); base stations 2 (Figure 2).

The WiMAX 18 fixed access network (Figure 2) (IEEE 802.16a standard) is a “user loop” of the RIVS, operates in the frequency range 3.3-3.8 GHz with the ability to work on the reflected signal. In this model, the WiMAX radio network is an ordinary IP network, on one of the segments of which radio waves are used as a transmission medium. It is characterized by a low density of base stations with a large service radius (up to 50 km, with a modulation type of 16QAM according to the specification) and low frequency resource consumption.

The gateways and interaction interface 3 (FIG. 2) are the interface nodes that connect the base station 2 (FIG. 2) of the WiMAX 18 network (FIG. 2) to the multiplexer 10 (FIG. 2) of the main network 17 (FIG. 2). The gateway and interaction interface 3 (Figure 2) provides connectivity both at the level of data channels and at the control level. It performs routing, relay functions, provides access to servers located on the network and local networks of subscribers. Physically, this is a 19-inch rack, it includes up to 10 slots for boards for various purposes and two independent power sources. Slots can be of three types: SRU, SPU, LPU. SRU (Switching and Routing Unit) performs the functions of collecting routing information, generates a routing table and sends it to the LPU and SPU boards, performs packet switching. SPU (Service Processing Unit) performs all the functions of processing incoming data. The LPU (Line interface Processing Unit) board is used to physically connect other network elements and performs the functions of transmitting data packets. Optical or electrical ports can be implemented on the board. Each of them is configured for urgent needs: connecting control and data channels to the main network 17 (Figure 2) or a radio network 18 (Figure 2), connecting base stations 2 (Figure 2), and servers for various purposes.

The regional computer network operates as follows.
