Object of the invention

Procedure for the simultaneous (convergent) transmission and / or distribution of voice, data, video (triple play) and radiofrequency for mobile telephony over a GPON (passive optical network) FTTH (fiber to homes) or FTTx (fiber optic network) fiber to the block), by using an electrical to optical converter that channels the signal through the fiber to a Metrocell (FTTx) or a Femtocell (FTTH) with a single client / user modem remotely controlled by software compatibility of systems and management of remote access control which, in turn, allows independent management of mobile phone services, Ethernet services (voice, data, video) of the GPON network, as described in the description and claims of the present invention.

Field of the Invention

The present invention has its application in the telecommunications industry and in particular in broadband access facilities on fixed fiber optic networks FTTx (fiber to the building) and in mobile networks LTE (long evolution terminal)

Background of the prior art

Mobile communications are mainly constituted by base stations, geographically distributed, dedicated to offer voice and data services in a given area, covering a limited area, coverage areas are divided into hexagonal spaces called cells or cells, assigning a base station by coverage cell with variable ranges and powers depending on the frequencies of the cellular network in question (GSM / 3G / LTE). This configuration allows the most efficient use of the frequency spectrum used and therefore the possibility of connecting many users at the same time.

During a communication the user connects through the nearest base station which, in turn, is communicated with the rest of the cells and with the other telephone systems (mobile or landline). This fact guarantees the communication in movement, that is to say, when the user is in movement and crosses different cover cells.

A base station is composed of different equipment that together constitute part of a mobile cellular telecommunications system and are composed of: shelters or containers to house the equipment necessary for the establishment of telecommunications and high-power tower structures (radio signal transmitters) and high altitude by virtue of the radio demand studies of each geographical area.

The increase in the demand for high-speed data services has led to the creation of new technologies and standards in mobile networks in such a way that they have significantly increased their speed in order to respond to the demand for these new services ( Example: mobile TV).

Telecommunications operators currently offer services supported by radio signals that should be distributed to users through broadband radio interfaces of mobile networks such as UMTS (third generation technology for voice and data transmission), HSPA (mobile internet standard! ) or LTE (long evolution terminal).

The growing demand for more and better voice and data services in mobile networks presents the following challenges:

• Increase in radio spectrum, limited by current legislation.

• Increase in the number of cells through subdivisions of the original cell, which requires greater infrastructure that multiplies expenses.

• Change of technology from the origin of 2.5G / 3G / 4G or LTE-Advance.

In the state of the art, fiber optic distribution technology to the home is known, as well as the use of radio over fiber optic, and, there are numerous methods and devices for the installation of fiber optic access networks called GPON (network passive applies) FTTH (fiber to housing), or, mobile telecommunications services that use LTE technology (long-term terminal).

A GPON network (optical passive network) FTTH (fiber to homes) is a passive optical network that uses a passive application splitter to provide and connect multiple services among many customers of a telecommunications operator, that is: connect the node of an operator of telecommunications from a device called OLT (line terminal applied), according to ITU T 984, with different users through an ONT modem (optical network terminal) in each one through which it provides multiple services called triple play (voice, data and video).

It is not known in the state of the art the implementation through a residential GPON fiber optic network (passive fiber optic network), in addition to the common triple play services (voice, data, video) simultaneously the radio frequency signal for telephony LTE mobile, through a single modem on the client side, so that the user will receive the signal from his mobile (3G, 4G) through the modem of his home (without the need for stations or base antennas), obtaining a dual connection with the modem via WIFI and via telephone signal (3G / 4G) of any operator in summary the services of GPON (optical passive network) FTTH (fiber to the homes) + LTE (long evolution terminal).

client separated by its wavelength of light that circulates in a single fiber wire until it reaches the splitter (separator box is an electronic interconnection device used in sound sockets to be able to separate several identical audio channels from a single source) which is also passive and this optical device divides only power into multiple outputs (eg an input with 8/16/32 optical outputs).

- The optical network terminal (ONT Equipment), where the applied distribution network (ODN) ends, reaches the customer's address to guide the traffic of the signals applied to the user and back to the exchange using a wavelength different (up and down links with optical carriers of different frequency), according to ITU-T standard. G984. This terminal equipment of the fiber network applies to the house has an input applied according to the previous ITU T standard and two or more Ethernet outputs 802.11 standard either physical by cable through an RJ45 mechanic connector or intangible with the same standard, by means of a wave of radio called "WIFI" that have the same effect: create in the modem an Ethernet data connection point according to IEEE standard 802 towards the optical network.

The procedures and installation of the converged telecommunications transmission equipment that the present invention proposes provides that a fixed residential network simultaneously supports the voice, data, video and voice services via the GPON FTTH network (passive fiber optic network to the homes). In addition, a mobile radio frequency signal service, through the implementation of the mobile network, that is, a simultaneous baseband distribution and the radio frequency signals provided by a radio access node through the use of a single ONT modem, without generating infrastructure changes that employ a GPON FTTH network.

The term convergent refers to the fact that each fiber optic network (ONT) terminal can simultaneously support digital Ethernet traffic and mobile broadcast radio signals.

Likewise, we will mainly use the topology of the GPON FTTH networks (physical or logical map of a network to exchange data), within the telecommunications services in an illustrative and non-limiting way to explain in a concrete way what the present invention proposes .

Mobile radio frequency signal networks, as we have indicated above, currently present problems of internal radio coverage in buildings or homes that cause the decrease of the data rate in customers located in areas of radio shadow even in conditions of high power irradiation radio frequency to minimize the problem generated by excessive distance or the existence of intermediate obstacles. This situation is due to the own configuration of the communications system that uses radio signal repeaters or transmitters in different circumstances and that is constituted by a system of nearby repeaters (base stations) and / or remote and the terminals themselves in which

It should be noted that the frequency bands assigned in each section of the communication are different to avoid mutual interference between transmitting and receiving antennas in the repeaters.

The present procedure incorporates and develops:

• a single client side modem.

• The antenna plus GPON residential fiber optic network radio equipment is housed in the same modem.

• Radio frequency emission sources at each client side point (ONT modem) of very low power, which can ensure reception / broadcast speed and the quality and / or constant coverage of communications.

• Multiple individual connections that reduce the concentration of traffic on mobile network antennas and avoid the problems expressed in the previous paragraph.

• Mobile technology management is independent of the GPON FTTH network.

• Creation of an electromagnetic irradiation point of LTE / LTE-A / 3G / 4G / 5G radio signals in each GPON residential client terminal.

• Transformation of residential fixed networks FTTH and networks in the street or block FTTx, in mobile networks.

As the present invention points out, it carries the radio frequency signal through the optical fiber creating an electromagnetic irradiation point of LTE / LTE-A / 3G / 4G / 5G radio signals in each residential client terminal, in such a way that it transforms The optical signal of the FTTH / FTTx fixed networks in radio frequency signal for mobile networks, convergence occurs in the fixed and mobile network transmissions over a fiber optic network, in what was originally done by installing networks and independent terminal equipment.

The antenna plus LTE / LTE-A / 3G / 4G / 5G radio equipment over residential GPON network is housed in the same modem that allows the provision of the GPON FTTH / FTTx service and its size has proportions not exceeding 150x30x60 mm.

This equipment and procedure solves the challenges and the aforementioned problem by providing wide coverage and increasing its capacity through multiple transmission points on the fixed fiber optic network at a very low cost with very low levels of indoor / outdoor electromagnetic irradiation (indoor / outdoor ) with respect to the antennas currently used by the base stations. All this greatly favors the expansion, installation and planning of broadband services for the LTE / LTE-A / 3G / 4G / 5G mobile network to the larger population.

The installation of this equipment ensures:

.- Optimum indoor signal / noise ratio.

.- Maximum speed and quality of mobile service.

.- Minimum radio frequency power.

The team provides fixed and mobile network telecommunications operators the possibility of offering jointly, by installing a single client-side modem, voice, data, video services simultaneously with mobile telephony as well as independent technical management of the mobile telephony of the GPON fixed fiber network.

This installation favors the provision of multiservices with excellent indoor coverage (indoor) by the operating companies to their customers by providing them with higher quality, thus favoring the deployment of mobile networks and reducing the costs of facilities, equipment, components and associated partners. to its maintenance (CAPEX AND OPEX).

Through the distribution of antennas on each client-side modem, the reduction in the speed of the emission / reception, the quality and the coverage of the communications are resolved according to the current radio propagation model of the mobile signal, which is produced by virtue of parameters such as the distances between the terminals and the repeaters (antennas), schedules in which there is greater concentration of traffic, the orography of the land and other physical obstacles of the architecture of buildings and homes.

The procedure is performed through the modem by four connections or interfaces:

• Optical interface to the node through the FTIH / FTTx GPON Optical network. ITU T 984 standard with the optical network terminal equipment on the OLT node (1), transporting the data packet from the GPON modem (2) to the telecommunications node (3) and from there to the fixed and mobile network.

• Electrical interface in the physical client. IEEE 802 ETHERNET Standard Converts FTTH / FTTx GPON optical traffic to electrical traffic in the form of an ETHERNET package with two equal outputs: wired and wireless (WiFi). It obtains electrical data output from a standardized optical frame with two identical IEEE 802 outputs on two different transmission means: UTP, mobile and wireless (WiFi) cabling.

• Electrical interface on the wireless client. IEEE 802 ETHERNET Standard Converts FTTH / FTTx GPON optical traffic to electrical traffic in the form of an ETHERNET package with two equal outputs: wired and wireless (WiFi) Obtains electrical data output from a standardized optical frame with two identical IEEE 802 outputs over two Different transmission media: UTP, mobile and wireless (WiFi) cabling.

• LTE / LTE-A / 3G / 4G / 5G electrical interface, for mobile network, converts the FTTH GPON application traffic to radio traffic in the form of LTE / LTE-A / 3G / 4G / 5G for mobile telephony. It obtains output for mobile network LTE / LTE-A / 3G / 4G / 5G from an optical modem with ETHERNET interface.

For the configuration of the equipment that the present procedural memory claims, advanced microprocessors have been used for LTE / LTE-A / 3G / 4G / 5G and a software has been created that combines GPON FTTH fixed optical network systems with the mobile network that remotely access (remote control) all parameters of the mobile operating transmission equipment independently to the GPON FTTH / FTTx system.

For this, a stage of low frequency broadband (2W) radio frequency has been generated on a direct current with irradiation capacity in frequencies ranging from 600 Mhz to 2.9 Mhz that can be modified by being constituted by a

data bus (computing device through which data is transported, information transmission channel within the computer that communicates the components of said system with the microprocessor) individual or independent that transmits over an Ethernet container to later be connected internally to the 5 GPON modem in accordance with ITU-T 984, a duplex (Full-duplex) T-CON channel or network that sends data both ways at once in IPV6 format (The transition between IPv6 providers is transparent to end users with the renumbering mechanism) if you send or receive information from; voice (VoIP), data (IP) or video (MPG4), from the node.

10 In this way, the referenced procedure can create as many LTE / LTE-A / 3G / 4G / 5G mobile network transmission points with high-speed (100 Mbps) and minimum delay (<2msg) data services over a fixed network fiber optic, as customers / users exist, producing high quality convergence in the transmissions of fixed and mobile optical networks with a single client side modem.
