Description

The invention relates to portable user wireless communication systems and, in particular, to routing devices used in wireless data networks to provide faster and more stable access to network resources, such as Internet servers.

Known technical solutions described in US patents:

(US 2005/0058141, M.C. H04L 12/56, publ. 17.03.2005,

US 2005/0058142, M.C. H04Q 7/20, publ. 03/17/2005,

US 2005/0068926, M.C. H04L 12/28, H04Q 7/24, publ. 03/31/2005).

The essence of technical solutions is to provide end users (consumers, consumer equipment) access to the Internet and network resources using a 3G, GPRS and analogue wireless cellular network by organizing access through a special device - a wireless access router. At the same time, consumer equipment can be connected to a wireless router via a Wi-Fi class wireless network or a wired Ethernet class connection.

Known devices include a processor (control unit), a transceiver unit (for a WLAN network), a transceiver unit (for a cellular network — 3G, GPRS, or an external card) connected to a processor that interacts with each other and with communication networks to be received by the user access to network resources. The transceiver units are equipped with a first and a second antenna, respectively, for connecting the processor to wireless networks and providing information from networks to multiple users through a matching device. This routing device may contain an additional matching device (LAN, WAN) associated with the processor to ensure interaction with various network systems and provide information from these networks to users.

The disadvantage of technical solutions US 2005/0058141, US 2005/0058142, US 2005/0068926 is the complete dependence of user access to the Internet or IP network from one wireless cellular network, the ability to use only one carrier frequency (one channel) of a wireless cellular network at a time time, which leads to insufficient speed and reliability of information transfer.

A known technical solution is the device of a mobile router for a wireless communication network (see US patent US 7778230, M.cl. H04W 4/00, publ. 08/17/2010), containing a set of routers, one of which is the main one, which includes the first processor (block control), the first memory block associated with the processor, the first and second interfaces of wired networks, each of which is connected to the first processor to provide access for users using a local wired or wireless network (LAN, WLAN) to the Internet or other external IP network . At the same time, each of the other routers contains a second processor (control unit), a second memory unit associated with the second processor, the first and second interfaces of wired networks, each of which is connected to the second processor and provides communication between user devices and wireless cellular networks under the control of the main the processor. The device also includes a first wired switch (switch) connected between the first interface of the main router and the second interfaces of one or more other routers for switching signals between the first and second processors, when using a wired network with the corresponding communication protocol; and a second switch connected between the first interface of one of the remaining routers and the second interface of the other of the rest, and this is used to switch signals between the second control units of the remaining routers.

The essence of the technical solution is to provide end users (consumers, consumer equipment) access to the Internet and network resources using a set of wireless cellular networks of various classes by organizing access through a group of devices (system) that provide the solution to the problem of organizing access and routing user requests through one from wireless cellular connections at one point in time for each specific information request. At the same time, consumer equipment, as well as in the above counterparts, can be connected to the system via a wireless WLAN network (for example, Wi-Fi) or a wired LAN connection (for example, Ethernet).

Thus, in patent US 7778230 it is possible to use only one of the available connections for receiving and transmitting information from and for one of the consumers at one time, which does not allow optimal use of the total bandwidth of all connected wireless cellular networks. At the same time, this technical solution provides load balancing only for outgoing traffic, incoming traffic goes along the routes corresponding to the outgoing routes, which can lead to delays in receiving significant amounts of information and reduce the quality of service for end consumers. In addition, the use of a set of nodes for access to wireless networks of various nature complicates the daily use of devices of this type. It should be noted that this system, like the previous analogues, does not provide information security and does not allow the use of combined means of authorization when using various types of external wireless communication networks.

The prior art systems and devices for aggregating communication channels [http://studopedia.ru/5_96707_agregirovanie-kanalov-svyazi.html], manufacturers of Fast EtherChannel and Gigabit EtherChannel from Cisco, MultiLink Trunking from Nortel, Adaptive Load Balancing from Intel and a number of other combining several physical ports into one logical trunk at the data link layer of the OSI model in order to form a high-speed data channel and increase fault tolerance. Their work is based on the fact that all redundant communications in one aggregated channel remain in working condition, and the available traffic is distributed between them to achieve load balancing. In the event of a failure of one of the physical channels included in such a logical backbone, traffic is distributed between the remaining physical channels.

Also known is a wireless router with a link aggregation system [https://www.mushroomnetworks.com/product/truffle], publ.: May 29, 2016. The principle of operation is based on the use of several modems with a cable line for channel aggregation, as well as wireless modems connected to the USB ports of the router. If one of the communication channels is unstable, the load of the download and data transfer packets is redistributed to others - more free and working.

A disadvantage of the known solutions operating on channel aggregation is the complexity and cumbersomeness of the router, the need to connect external communication devices to it through ports that slow down data processing, as well as additional devices with their own chips slow them down.

Such systems cannot be used as user portable routing devices due to the large size and the many connected communication devices and many channels. In addition, they can only work in the system. The closest analogue is the routing system for a wireless information transmission system (patent RU 125007U, publ.: 02.20.2013.), Comprising in the subscriber part interconnected input / output buses, a local wireless network transceiver unit (WLAN), a routing control unit, a unit N interfaces for accessing external wireless networks, where N is the number of external wireless networks, a subsystem for interacting with a local wired network (LAN), a subsystem for interacting with a local or external wired network (LAN / WAN), characterized the fact that it contains a network part, in which there is an additional routing control unit, connected by an input / output bus with a subsystem for interaction with local or external networks (LAN / WAN), the other input / output bus of which is used to connect interaction ports over a wired network, wherein the routing control units of both parts are configured to divide into parts and summarize the parts of the source information. It provides an increase in the speed and quality of data transmission by reducing delays in the reception and transmission of information during the implementation of frequency switching procedures, access codes and other procedures that take place in a wireless communication network, as well as ensuring secrecy in the transmission of information and the possibility of using combined and convergent means authorization and authentication when using external wireless communication networks of various types.

The disadvantage of the solution is that in the prototype there is a division into pieces of information in the block, and then these pieces of information with new addresses of recipients of IP packets - addresses of the network part of the routing system, are transmitted simultaneously through various communication channels, through various networks.

This leads to the fact that in the event of the loss of one packet in one communication channel when one of the communication modules freezes, all file sending is also lost, since it arrives corrupted (without 1 packet). And if the file is large, then the loss is fraught with the loss of traffic to re-download. As a result, the quality of data transfer is doubtful, the whole point of increasing the speed from increasing traffic and time to re-upload or send files is lost.

Since the IP addresses of sending packets for each of the channels of wired or wireless communication are different, the disadvantage of the prototype system is the need to configure the network part of the system corresponding to the subscriber part of the routing system, which would identify all addresses to a single user and combine all packets going through different communication channels . Those. reconstruction of networks is required, and in unchanged networks, a prototype system will not only not work efficiently, but will generally not work.

The objective of the claimed solution is to eliminate the disadvantages of all known solutions and prototype.

The technical result of the invention is to simplify the design of the router with the function of aggregating channels, reducing the size, speeding up the process of transferring download packets and data transfer when redistributing the load, eliminating the need for any changes to the network part (work within the framework of modern communication networks).

Preferably, through a remote server monitor and control the operation of the device.

Preferably, when sending or receiving a complete set of file packages through one of the networks of the interface unit or through the subsystem for interacting with a local wired network (LAN), the remaining unsent or unreceived file packets traveling over other networks are redistributed to free wireless networks or a free local wired network (LAN).

The implementation of the invention

A device for providing broadband data services, operating according to the above method, can be performed in a single housing 12, inside which are located the interconnected input / output buses, the local wireless network transceiver unit 1 (WLAN), the routing control unit 2 with microprocessor module 8, an interface unit 4 for accessing at least two external wireless networks, for example, via a Wi-Fi wireless communication module 9, or via an external USB port 10 and an LTE modem 11. The device also contains subsystem of interaction with a local wired network (LAN) 3, subsystem of interaction with a local or external wired network (LAN / WAN) 5. The corresponding input / output buses block 2 controls the routes and interaction of subsystems is connected to the block of local wireless network 1, the subsystem of interaction with local wired network (LAN) 3, block 4 and subsystem 5, which is connected to port 7 by another input / output, and another subsystem 3 output / input is connected to interface unit 6.

The routing control unit 2 is configured to divide into parts and summarize parts of the source information.

The microprocessor module 8 of the routing control unit is configured to aggregate several channels — local channels and / or wireless data transmission channels into a single logical data transmission channel. Wireless modules 9 and 11 of the interface unit 4 can be performed on a single printed circuit board, or in the form of separate external devices connected via external ports 10, for example, USB ports.

The method of providing broadband data services to the mass consumer can be implemented as follows. Using the hardware part consisting of the above-described elements of the device 12, in which the routing control unit 2 is used for dividing 17 (see Fig. 4) into parts and 22 summing (see Fig. 5) parts of the initial information, and parts of the information are transmitted simultaneously through various communication channels, through various networks to a single recipient address. Routing control is carried out with the possibility of aggregation of several channels — local channels 5 and / or wireless data channels 4 into a single logical data channel.

Separation of 17 into parts of transmitted 18 and received 20 parts of information is carried out in separate file packages, taking into account the bandwidth and signal quality of each of the transmission channels of the interface unit 4 and the subsystem for interaction with a local or external wired network (LAN / WAN) 5, based on the fact that larger files are sent for transfer and downloaded via channels with higher bandwidth and better signal quality, and smaller files are sent for transfer and downloaded through channels with lower bandwidth with individuality and poorer quality signal.

After sending 13 signals or files from the consumer through the block of the local wireless network 1 or the subsystem of interaction with the local wired network (LAN) 3, they receive and analyze 14 request / send data requests. The process of evaluating the choice of sending from the consumer 13 the received information in the routing control unit 2 after preliminary testing 15 for analyzing the bandwidth and signal quality of each of the wireless networks of the interface unit 4 and the local wired network (LAN) 5, where the ranking of 16 networks from better for worse, with testing 15 and ranking 16 repeated at the time of inactivity (lack of incoming and outgoing traffic 19), and with the beginning of its flow, use to send or download files s recent test results chains and ranking.

It is permissible that through a remote server they monitor and control the operation of device 12 and the state of its elements.

When sending or receiving a complete set of a package of files through one of the networks of the interface unit or through a subsystem for interacting with a local wired network (LAN), the remaining unsent or undelivered file packets that go over other networks can be redistributed to free wireless networks or a free local wired network (LAN). This reduces the load on other working networks due to the redistribution of load on inactive ones.

After analyzing 15 the availability of access interfaces and their performance, the signal quality (testing) and ranking of 16 networks, when sending files or when receiving a packet, 17 data is divided into files and the volume is distributed across networks depending on the ranking.

When receiving data during reception 20, the data is first evaluated by 22 according to the size of the received packet and the number of files through the fastest communication channel determined during ranking. As a result, 22 packets of received data are estimated by volume and files, and then 17 data is divided into files and volume distribution by network depending on the ranking, after which the initial request / package 21 is transmitted to consumer 13 via the local wireless network unit 1 or the interaction subsystem local area network (LAN) 3.

The invention, implemented using the method and device, aggregates many data channels into a single logical data channel, thereby providing better data channel characteristics than the capabilities of each individual wireless module.

The use of the invention allows the provision of data services at speeds exceeding the capabilities of each individual wireless data transmission operator, increases the reliability of data transmission in excess of the reliability of each individual wireless data transmission operator. Possible wireless modules used for the interface unit may include the following devices: wireless 2G / 3G / 4G / 5G mobile communication modules for CDMA / WCDMA / UMTS / GSM wireless networks; Wi-Fi wireless modules. The method of aggregation of multiple data transmission channels into a single channel does not allow the maximum use of the resources of aggregated data transmission channels to achieve high characteristics of the formed logical channel.
