The technical field to which the invention relates

The present invention relates to methods and systems transmit information through various information networks and, in particular, to a method of transmitting information in a unified communication system and broadcast and can be used in the provision of a new type of multimedia communications and broadcasting services to consumers in different regions, which are deployed in modern cellular communication system.

The level of technology

With the rapid development of the market of multimedia services provided to the consumer on the basis of high-speed digital broadband information has dramatically increased the interest of the operators of cellular and broadcast networks to hybrid networks with advanced volume of traffic through the integration of resources such networks.

When existing networks are used to transmit high-speed broadband information (audio, high-quality video in real time, a large amount of data), while cellular communication system used to implement the traditional functions of the cellular communication system (voice, messaging, short message service (SMS) and others) and as a back channel during the implementation television on request.

Interest in the transformation of aniu systems mobile communication systems with advanced features and resources increasingly attracted researchers from various firms.

So in a publication of the international application WO97/41704 (06.11.1997) disclosed a method of conversion of the cellular communication system of the first generation of cellular communication of the second generation, which includes switching centers, the mobile communication base station and mobile terminals. The proposed evaluation method allows to increase the capacity of the traffic system of the first generation by introducing mnogolistovyh nodes, at least one base station and the introduction of universal equipment, the base station is able to support both generations and transfer using radioresource, when it is desirable or necessary from the system first generation second generation by reconfiguration universal equipment of the base station.

The patent application U.S. A (15.06.2006) discloses a method and system for cellular network and integrated broadcast television downlink to the mobile terminal with intelligent control services without feedback, intended to communicate a variety of networks, including cellular networks for processing services of cellular networks: at least one voice service and one service data of the mobile terminal and the network broadcast, intended for processing and providing, at IU is e, one of the services in the VHF/UHF band mobile terminal.

As cellular networks in the integration of broadcast television descending line of communication can be used known cellular communication system GPRS, EDGE, UMTS, GSM (superior and third generation (3G))that uses packet-switching technology in wireless networks.

Data cellular communication system can be used when implementing hybrid networks for the delivery of broadcast and multicast (multicast) services that also use IP technology DC (IP Datacast).

To provide broadcasting services (digital television, the transmission of audio and data) used line deployed broadcasting systems standard DTTB (digital terrestrial television broadcasting) and their variants DVB-T, DVB-H, or ATSC and ISDB-T.

The integration of services provided by the cellular network and a digital broadcasting network, as well as the interaction of two independent (with full infrastructure) networks by using the service control center, performs control functions and the distribution of information in an integrated system.

The disadvantages are proposed in this application is the data transmission method and integrated system should include the following:

1. Integrated system built on the basis of two itself is independent networks and implies the presence in each of the networks full infrastructure including a full set of equipment, communication lines and capital structures, for example, the broadcast network is a costly tower (height 75-120-200 meters), antenna systems and transmitters high power (hundreds of KW) with a powerful power sources.

2. For development proposed in this application of the integrated system, i.e. to increase the coverage of broadcast signals and the number of subscribers to the services of the broadcast network requires the construction of new permanent structures, strip them of new communication lines (or sets of repeaters), which requires a significant financial cost and additional time resource.

3. The proposed method of transmitting broadcast information in an integrated system through the use of high mounted antenna systems and transmission equipment is not universal and does not provide a high quality of reception of the broadcast content network subscribers that are located in areas where the signals are line-of-sight is not possible. Such conditions of radio propagation is typical for areas with difficult terrain and cities with high-rise buildings and result in a significant (up to 35-40 dB) the attenuation of the received signal and, as a consequence, deterioration of the reception quality of the broadcast information specified by the relevant standard and the mouths.

In the patent application U.S. 20060251115A1 (09.11.2006) the proposed implementation of broadband multiplug, switching, and transmission of information, and proposed a distributed architecture for creating telecommunication networks with minimal financial costs of their implementation. Distributed broadband multi-service communications network low cost includes intelligent hybrid communication nodes that interact with each other. Hybrid nodes have multimedia interfaces and processors that allow nodes to receive the broadcast information using one Protocol interface, to transform this information into another Protocol format and distribute it through interfaces with various protocols used to transfer other information environments.

The disadvantages are proposed in this application of the method of performing broadband multiplug, switching, and transmission of information and design of the network should include the following:

1. Limited applications due to the small coverage area, due to the limitation of power transmitting devices. Limitation of power transmitting devices due to their placement inside an airtight compartment module, small size module, harsh conditions of heat and, as a consequence, e is Oh, hard requirements for allowable thermal regimes transmitter module.

Therefore the main purpose of the system using a transmitting devices low power and is providing services in suburban and rural areas on the edge of the coverage area of the signals of existing cellular networks, where the use of such systems economically feasible.

2. A limited number of subscribers served by the same node (9999) and the inability of customer service coming from other areas (not roaming), which is also related to the small size of the database and due to miniaturization of complex equipment and the proposed architecture.

3. The network does not include suppliers of broadcast content.

Receiving broadcast content proposed to be implemented by connecting a network or to existing land line providers broadcast content or satellite communication lines, which would require additional financial costs. In the absence of such lines in the area where you want to deploy such a system, organization of reception of the broadcast content can lead to large financial costs.

Thus it can be argued that in the proposal the transfer method and the architecture of the network are in addition to sushestvuyuyut cellular communication in order to increase coverage through the use of network equipment, placed in one container and perform the minimum functions of a modern cellular networks.

Expanding your multimedia entertainment services for transmission to mobile terminals attracts great interest operators of broadcast and cellular networks to transmit to the mobile terminal, a high definition television, stimulates the search for new solutions in the organization of interoperability of existing systems of broadcasting and communication, and the search for new architectural principles for building hybrid networks.

So ALCATEL in the project "Unlimited mobile TV for the mass market" proposes the use of hybrid terrestrial and space (satellite) architecture that combines the capabilities of existing terrestrial mobile networks, the 3rd generation (3G/UMTS) and satellite communication S-band (2 GHz). To receive satellite TV programs broadcasting DVB-H and their subsequent distribution (transmission) on terrestrial mobile terminals, in addition to the existing segment of satellite broadcasting, ALCATEL proposes to use the existing base station of the 3rd generation (3G/UMTS) - ALCATEL NodeB with repeater's range integration with existing network equipment land mobile ALCATEL and other manufacturers.

Thus, the existing methods of integration of broadcast networks and with the new communication networks offer or develop a new hybrid equipment, combining the functions of both networks and centres of their control, or joint use of existing separately from each other broadcast and cellular networks.

In most regions of the broadcasting infrastructure serviced by the cellular networks territories is missing and the deployment of such a hybrid system that meets modern requirements delivery to a user of the multimedia content requires large expenses and a considerable period of time due to the need for the construction of permanent structures (e.g., broadcast antenna towers 70-200 m, strip lines or installation of repeaters wireless communication lines), acquisition, installation and testing of equipment, which means the almost complete new infrastructure broadcasting network.

There is therefore a need for significant expansion of services provided to users of mobile communication networks through the creation of joint communication and broadcasting systems, using well-known advantages of cellular networks, such as:

- high quality communications services regardless of the location of the subscriber on the service network of the territory and terrain;

residual low financial costs of increasing coverage and the number of subscribers at the expense o f the s new base stations and new cells cell network;

- the economic benefits of the service areas with low population density and ease of service and payments for services rendered.

Such problems are fully resolved on the basis proposed in this application of the method of information transfer and joint communication and broadcasting systems.

This service broadcasting network (audio, video, and data) can be provided in a unified communication system and broadcast in full and the new fixed users connected to the cellular networks, which will lead to a significant increase in the number of subscribers of cellular networks and increase the income of operators and suppliers of broadcast content.

The availability of backbone networks with packet switching in deployed cellular networks and their use in the integrated system of communications and broadcasting will provide data of any type and will be transported in a single stream combined communication systems and broadcasting all known types of information (audio, video) with their subsequent separation and distribution through the base station and broadcast equipment, and thereby provide access to the subscribers of the merged communication system and broadcast to the total volume of multimedia communications and broadcasting services.

Physical implementation and industrial applicability

The physical implementation of the invention a method and system for transmitting information in a unified communication system and broadcast confirmed by the results of research and field testing compatibility of cellular and broadcasting systems and compatibility of digital broadcasting systems standards DVB-T and DVB-H, deployed in the same geographical area.

The results of field tests carried out in England, Germany, France, fully confirmed theoretical conclusions about the possibility of joint operation of these systems without mutual influence on each other and without compromising the quality of services delivered to subscribers each system.

Proposed in the present invention unified communications and broadcasting when placing the transmitting equipment of the broadcasting network to the base station of the cellular communication network and transmitting antennas broadcasting network next to the receiving-transmitting antenna of a cellular network (one mA who those) ensures the normal functioning of the equipment combined system without mutual influence equipment component parts to each other.

This is achieved, firstly, due to the spacing of the frequency band allocated for transmitting signals of the broadcasting network and a bandwidth allocated for transmitting signals to the cellular network and the corresponding frequency planning in the internetwork, and, secondly, due to the spatial separation of vertically transmitting antennas of the signal broadcasting network and receiving-transmitting antenna signals of the cellular communication network located on the same antenna mast antenna complex base stations.

As you know, when placed on a single mast broadband antenna with a wide beam pattern and spacing vertically at 30 centimeters or more, even when operating systems on a single frequency in the VHF range, provides isolation between the antennas more than 50 dB, which virtually eliminates any impact of transmitters broadcasting system parts on two-way radios cellular network. Moreover, the achieved values of the decoupling of the antennas do not depend on the width of the directional diagram of the antenna in the vertical plane and their inclination relative to the horizon and each other, allowing you to use as base station antennas integrated system of communications and broadcasting standard antenna base stations of cellular networks, such as sectorial antennas, phased array antennas the lattice, adaptive antenna without any restrictions on their characteristics.

With significant spacing operating frequency range networks (e.g., 800 MHz and 1900 MHz) level of isolation between antennas located at a distance of 30 centimeters or more, 60-70 dB.

According to the present invention for transmitting digital television, high quality mobile and fixed terminals combined communication and broadcasting systems are encouraged to use the standards for terrestrial digital TV broadcasting (DVB-H and DVB-T.

Use in broadcasting network format IP Datacast over DVB-H allows you to ensure the delivery of any type of digital content from the source to the consumer using the underlying mechanism IP, and allows you to optimize the maintenance and processing of content by the mobile terminal with limited computational capacity and limited resource supply.

Unified communications and broadcasting is implemented on the basis of supplied complete standard equipment of modern cellular networks, or on the basis of already deployed cellular networks, with extra standard equipment control network broadcasting and transmitting equipment for terrestrial digital television broadcasting standards DVB-H and DVB-T on the existing base station.

For example, merge the network communications and broadcasting can be used with the following equipment:

-Transmitters Audemat - Aztec

-Transmitters DVB-T/H Harris

-DVB-H IPE-10 Encapsulator UDcast (Harris)

-DVB-H IPE Manager UDcast (Harris)

-PT 5781 Single board OEM DVB-T/H Modulator ProTelevision Technologies

To ensure the required coverage broadcast network in the integrated system of communications and broadcasting, coinciding with the coverage area of a cellular network, the power level of the transmitter broadcasting network must be in the range of 10-50 watts. The specific value of the power of the transmitter is determined by the radius of the cell size (coverage area), the terms of the placement of antennas of a base station of a cellular network, the characteristics of the territory in which the network of cellular communication (city, suburb, rural)that guarantees 100% chance of covering the territory of the broadcast signal of the desired level of field strengths specified in the relevant standards.

Providing the required level of signal when using transmitters indicated power is confirmed by numerous publications on testing of broadcasting systems and measurements of the levels of the broadcast signal points of the reception signal standards DVB-H and DVB-T.

The honeycomb structure is proposed in this invention is an integrated system of communications and broadcasting allows you to create schedule for specific individual cell, and for the system as a whole.

In addition, the proposed who ructure allows you to attract local providers of broadcasting content to create programs broadcast in a specific selected area and provides an additional possibility of forming a broadcast program for a specific the user group.

All this allows you to build a flexible system for delivering broadcast content to subscribers of a unified system of communication and broadcasting, on which deployed and operate a cellular network, and broadcast networks are absent or broadcasting quality does not meet modern requirements.

As terminals for receiving broadcast content can be used by the mobile terminal with a function of receiving signals in DVB-H, fixed terminal with a function of receiving signals in the DVB-T and analog TV receivers TV, upgraded by connecting set-top boxes to receive digital television (DVB-T.
