Description

The method and system of Internet service is provided

The present invention relates to provide Internet service, being specifically related to provides Internet service by the wireless radio transmission net.

Most of Russian cities share set up the 1830's be used for broadcast radio program and under the state of emergency and the state of war as the wired radio transmission network of the device of government and its citizen's secure communication.After the initial installation of this wireless radio transmission net, it is constantly expanded and upgrades.

The wireless radio transmission net in Russia city comprises the infrastructure of the telecommunication line of each resident that is connected in the city and commercial establishment.In each this building, some copper twisted pairs are connected to each subelement (self-contained flat, office etc.) in the building with telecommunication line.Each subelement is equipped with one or more jack/outlets that are used to be connected to radio receiver.For example, have in holy Bhide fort and peripheral suburb and surpass 3,100,000 the radio jack that is used for resident and commercial.For supporting this wireless radio transmission net, this zone has been laid and has been surpassed 5,000 kilometers telecommunication line.

For introducing up-to-date suitable technology, the wireless radio transmission net is upgraded repeatedly.The existing hardware that holy Bhide fort net uses allows the wireless radio transmission of three kinds of programs.Except that other service, the speech transmissions that this net uses earlier and then multiplying arrangement provides very little distortion efficiently.So far, this wireless radio transmission web frame only is used for radio.This net never is used to provide Internet service.

Internet transmission network known today has some shortcomings, comprises following aspect.Can not 1 based on the internet access network of dial technology (public telephone line)) simultaneously all its customer are connected to Internet service; 2) effectively utilize bandwidth resources; Or 3) user and the service for varying level provides just in time suitable data rate.

Because must use the internet access network of the communication channel of distributing can bring extra operating cost for each potential user provides an independently access channel, this causes the internet use cost to increase.

Because representative value can not surpass the restriction of the maximum usable data rate of 8Mbps, use the internet access network of ADSL Modem to limit network system.These networks also need be located installation of additional equipment at telephone exchange station and each user, have extremely increased cost of serving.

Electrification line telecommunications (PLT) technology is restricted to " arrowband " as the internet access solution and uses, as remote measurement.This technology mainly is only applicable to reduce the operating cost of electric company, and faces the problem of shortage standard and mutual performability.

Radio network technique limited bandwidth (maximum 50Mbps) does not have ripe telecommunication standard and infrastructure, and also than other internet access technology costlinesses.

In general, the present invention includes and utilize existing radio transmission line to realize that the internet inserts and the system and method for technology (IT) service for information about, and do not disturb the basic purpose-radio program broadcast of wireless radio transmission net and in case of emergency government issue specific notification to its citizen.

First preferred embodiment of the present invention comprises the method and system that Internet service is provided by the existing radio transmission network.

Fig. 1 describes traditional wireless radio transmission net.This network comprises the broadcasting studio 100 as the source of the radio programming of all transmissions.Broadcasting studio 100 is connected to audio distribution center (ADC) 110 by two copper cash 105.Similarly, ADC110 is connected to a plurality of base amplifier platforms (BAS) 120.Each BAS120 is connected to ADC110 by its oneself two copper cash 115.

ADC110 comprises that a plurality of being used for receives radio signals and send the amplifier of amplifying signal to BAS120 from broadcasting studio 100 (by copper cash 105).Each BAS120 also is included as and further transmits the amplifier that the radio signal that receives is amplified downstream once more.More specifically, each output of BAS120 is connected to the transducer station 130 between building.

Transducer station (ITS) 130 between each building comprises by the input of copper cash 125 from the BAS120 received signal.Each ITS130 comprises inlet/input filter 910, transducer 920, outlet/output filter 930 and distribution transducer 940 (see figure 9)s.Each ITS130 also comprises the output at the transducer station (STS) 140 that is connected to a plurality of single buildings.

Typically, each STS140 is associated with single building (as compound apartment or office building).STS140 comprises the input that receives radio transmissioning signal from ITS130.STS140 also comprises and is connected to copper cash to 145 output.Copper cash 145 passes whole building to a plurality of radio sockets 150, and typically, each radio socket 150 is contained in the self-contained flat or office in the building.Each radio socket 150 is connected to radio speaker, to produce the voice signal of the radio signal representative that receives by copper cash 145.

Utilize this network, broadcasting studio 100 sends radio signal by copper cash 105 to ADC110 and comes broadcast radio signal.ADC110 amplifies the radio signal of reception and sends amplifying signal once more to corresponding BAS120 by every pair of copper cash 115.Each BAS120 amplifies the radio signal of reception and sends amplifying signal once more to ITS130 by every pair of copper cash 125.Each ITS130 changes this signal and sends the signal of this conversion to a plurality of STS unit 140 by copper cash 135.Each receives STS140 and changes this signal and send the signal of this conversion to a plurality of radio sockets 150 by copper cash 145.Therefore, the radio signal that is sent by broadcasting studio 100 propagates into each radio socket in the network by whole radio net.Typical this radio signal is in the 0-10kHz scope.

For simplifying explanation, we are arranged in self-contained flat by each radio socket of assumed wireless electrical transmission net, although in the superincumbent discussion, this socket also can be in office, each room or the like.After this, used here " self-contained flat " (apartment) speech be often referred to any place with the radio socket that is connected to the wireless radio transmission net.

The existing radio transmission network that the preferred embodiments of the present invention utilization is above described provides service based on the internet to the self-contained flat with radio socket.(see figure 2) in optimum decision system, center exchange and Route Selection unit (A-1) 220 are installed in the structure that ADC110 is housed.The A-1 unit is preferably the main operation point of system, and is connected to internet 210 by high speed fibre line 205.The service quality and the fail safe of its monitoring, control and management whole system.It also carries out exchange and the Route Selection that is used for system; Support IP phone, IP TV inserts at a high speed and other internet/in-house network is used; The system that is provided to internet 210 inserts; And for system user and keeper provide database service.The following table 1 of preferred assembly that constitutes the A-1 unit is listed.

Preferably, the A-1 unit is connected to exchange of a plurality of zones and Route Selection unit (A-2) 230 by underground optical fiber cable 215, and each zone exchange and Route Selection unit (A-2) 230 are installed in the structure that BAS120 is housed.Each A-2 unit is the main operation point of a Local Area Network, and this Local Area Network typical case comprises 60-100 resident's building or commercial building.The A-2 unit is that whole Local Area Network is carried out exchange and Route Selection; Support IP phone, IP TV inserts at a high speed and other internet/in-house network is used; And for the other parts of system provide access.Because being typically 60-100 building, each unit provide service, the quantity of A-2 unit 230 to depend on the quantity of building in the zone.The following table 2 of preferred assembly that constitutes the A-2 unit is listed.

Shown in Fig. 2 and 3, each A-2 unit is connected to one or more low-speed modulation/demodulation devices (LSM) 170.It is right that each LSM also is connected to the copper cash of wireless radio transmission net, preferably is connected on the copper cash 125 between BAS120 and the ITS130.LSM is from the signal of A-2 unit receiving internet transmission and transmission once more on copper cash 125.Term " low-speed modulation/demodulation device " is only represented to transmit but not the optical fiber cable of higher speed by copper cash--and do not require the actual speed that is lower than by the high speed fibre line of transmission rate.Similarly, undue restriction do not wished in term " modulator-demodulator " yet.In fact, LSM240 preferably meets the 10Base-S switch of 10Base-S agreement, but not " modulator-demodulator " of traditional sense.Yet, one skilled in the art will realize that and can use various modem type (" modulator-demodulator " that for example, comprise ISDN and DSL-class) and host-host protocol.

Signal by transmission on the LSM240 online 125 is forwarded to a plurality of STS unit 140 by ITS130.Then, each STS unit arrives in its relevant building by the signal that sends the signal forwarding transmission on copper cash 145.

As shown in Figure 2, some self-contained flats can comprise the LSM270 of the radio socket 150 that is connected to self-contained flat, are used to receive the Internet transmission on online 145.Each LSM270 is connected to people's computer 280 one by one.In this way, computer 280 can the receiving internet information transmitted.Equally, because modem signal does not disturb existing radio signal by wireless radio transmission net transmitted in both directions, computer 280 also can send the information of Internet transmission by LSM270.This information transmitted propagates into STS140 by building line 145.Then, STS140 transmits information transmitted to ITS130 by line 135.Equally, ITS130 transmits information transmitted to LSM240 by line 125.LSM240 receives the information of this Internet transmission and transmits them to A-2 unit 230 from line 125, and then, A-2 unit 230 sends to the internet by optical fiber 215, A-1 unit 220 and optical fiber 205 with these signal upstream direction (upstream).In a preferred embodiment, each LSM240 is 10Base-S switch and router, and each LSM270 is the 10Base-S interface.

Other self-contained flat can comprise the high-speed interface card HSC260 that is connected between building line 145 and the personal computer 280.Each HSC is the network interface unit of communication between building line 145 and personal computer 280.For making this HSC card can be by Internet traffic, each A-2 unit 230 be connected to a plurality of A-3 unit 250 by high speed fibre line 255, and each unit is arranged in single building.Each A-3 unit 250 is connected to the line 145 in the building.250 usefulness these existing lines in A-3 unit constitute the local area network (LAN) of this building.

In a preferred embodiment, HSC260 and LSM270 are to use the network interface of 10Base-S agreement.Utilize each HSC/LSM unit to communicate by letter with LSM240 or A-3 unit 250.The HSC/LSM unit depends on user's subscription level with the unit communication of which kind of type: highspeed user's HSC/LSM communicates by letter with A-3 unit 250, and the HSC/LSM of low speed user communicates by letter with LSM240.The A-3 unit can with the high-speed interface cartoon letters that adopts 10Base-S, 100Base-T or 1000Base-T agreement.

Each A-3 unit 250 is the point of the main operation in the building of high-speed local area network preferably, and this high-speed local area network is formed by the personal computer 280 that the HSC260 by the highspeed user is connected to building copper cash 145.250 pairs of all computers as its local network part in A-3 unit are carried out exchange and Route Selection.A-3 unit 250 preferably is connected to A-2 unit 230 by optical cable 255, and optical cable 255 is the overhead wires that supported by the feeder that is positioned on the building top, though but also land used cable or non-optical fiber component cable.The following table 3 of preferred assembly that constitutes the A-3 unit is listed.Fig. 3,4 and 4A described the physical connection of A-1, A-2 and A-3 unit and its inter-module.

Therefore, for the self-contained flat unit that comprises HSC card 260, by the higher speed passage that the optical cable 205,215 and 255 that is linked by A-3 unit 250, A-2 unit 230 and A-1 unit 220 and they forms, personal computer 280 can be by Internet traffic.Yet, for the self-contained flat that only comprises LSM interface card 270 (that is: this self-contained flat is a low speed user), by another passage that the line that linked by SST140, ITS130, LSM240, A-2 unit 230 and A-1 unit 220 and they and optical cable form, personal computer 280 can with Internet traffic.

10Base-S is preferably used in LSM unit 240 and 270 ^TMSystem (can be from being positioned at Israel, mailbox 196 approximately can clothing sharp special 20692, the female Electronics Co., Ltd. of Ou Leng card (OLENCOMElectronics Ltd., Yokneam Illit 20692, P.O.B.196, Israel) obtain), or similar system, be used for transmitting by copper cash.Equally, the A-3 unit 250 10Base-S protocol communication identical with HSC unit 260 usefulness.

The 10Base-S system provides the expansion to the 10BaseT ethernet standard network that meets IEEE802.3.Its combination DSL modulation technique and ethernet technology.The 10Base-S system provides the link of point-to-point, and this link can transmit half-or full-duplex 10BaseT Ethernet with the full rate of 10Mbps.For phone application, it supports to transmit POTS or ISDN or PBX signaling and data simultaneously by the line tower foundation facility of standard telephone level.

The 10Base-S system adopts quadrature amplitude modulation (qam).The QAM modulation defines each code element with signal amplitude and phase place.10Base-S uses the most complicated QAM technology with various QAM modulation (QAM256, QAM128, QAM64, QAM32, QAM16, QAM8 and QAM4).Concrete modulation is selected according to circuit standard and data transfer rate definition.For reaching the performance that is bordering on physics limit most as far as possible, the 10Base-S of design will support many QAM, and keeps low cost and low energy consumption.When calculation of capacity (calculating of physics tolerance limit) relatively, 10Base-S is bigger than DMT TDD and common QAM capacity.

The convenient symmetrical bi-directional data on unscreened copper twisted pair cable of 10Base-S transmits.The 10Base-S system adopts Frequency Division Duplexing (FDD) (FDD) separate downstream channel, upstream channel and POTS, ISDN or the service of PBX signaling in frequency domain.This makes the service provider can not destroy existing P OTS, ISDN or the PBX signaling is served and the 10Base-S that superposes on them.10Base-S and POTS/ISDN/PBX service all can be transmitted and non-interference on same circuit.With proprietary scheme Ethernet data is encapsulated in the continuous cell flow.System uses motor synchronizing scramble mechanism to this continuous non-bursty data cell flow.Scrambler is initialized to one and provides the random value of decorrelation preferably to the signal that sends, therefore, and by many FEXT performances preferably that obtain when copper cable is sent.A kind of senior auspicious moral Saloman (RS) error correcting code also is applied to data flow, and very strong error detection and recovery capability are provided.When receiving, be reassembled into Ethernet data from error-free cell flow.The 10Base-S technology is moved to data transfer rate with the continuous original symmetric double of 11.25Mbps.This allows Ethernet data to transmit with the full standard circuit speed full duplex of 10Mbps.This transmission expense can not reduce the Ethernet bandwidth, and therefore, system can be used for the Ethernet of 10Mbps fully pellucidly.

The 10Base-S system can be used as substantial point to point communication system.Core data pump (core data pump) is a blind modulator-demodulator (blind modem), and the energy support point is to multicast system.Operation under the point-to-point situation is supported full-duplex operation simultaneously by not using the collision detection scheme from upstream data frequency separation downstream data.Actual Ethernet interface is the standard Registered Jack-45.The user can use the standard ethernet cable that standard 10BaseT equipment (as Ethernet switch or Ethernet NIC card) is connected to 10Base-S equipment.

Because 10Base-S through-put power and frequency and wireless radio transmission power and frequency fundamental difference, 10Base-S transmission and not mutual interference mutually of wireless radio transmission on same line on online 145.More specifically, radio signal is compared with the 10Base-S transmission and is had low-down frequency range (0-10kHz).Further, radio signal is compared with the 10Base-S transmission and is had very high power.Therefore, when the user opened the radio unit that is connected to radio socket 150 and listens to radio programming, because the higher frequency of 10Base-S signal, the loud speaker of radio unit is filtering 10Base-S signal in large quantities.Further, comprise the situation of the frequency component in the speaker bandwidth,, can not reproduced with finding by loud speaker because its power is very little for the 10Base-S signal.

Fig. 4,4A and 4B show the more detailed the block diagram how assembly that is used to form A-1, A-2 and A-3 unit and they are connected.

Fig. 5 generality is described the operation of network when unique user enters the Internet by low-speed modulation/demodulation device 270.In an example shown, in step 510, A-1 unit 220 receives the internet data that is assigned to this user.Then, in step 520, the data of A-1 unit 220 these receptions of Route Selection are to the A-2 unit 230 that service is provided as member's regional network to this user.In step 530, A-2 unit 230 receives and these data of Route Selection arrive LSM unit 240, and it provides service for the building at this user place (also comprising other building usually).In step 540, LSM unit 240 receives these data and sends these data (preferably using the 10Base-S agreement) by LSM270 (being preferably 10Base-S end user unit) to user's PC280 by STS140 on the wireless radio transmission circuit.

Fig. 6 generality is described the operation of network when unique user enters the Internet by HSC260.In an example shown, in step 610, A-1 unit 220 receives the internet data that is assigned to this user.In step 620, A-1 unit these data of 220 Route Selection are to the A-2 unit 230 that service is provided as member's regional network to this user.In step 630, A-2 unit 230 receives and these data of Route Selection arrive A-3 unit 250, and it provides service for this user's building.In step 640, A-3 unit 250 receives these data and uses the 10Base-S agreement to send this data by HSC260 to user's PC280 by wireless radio transmission circuit 145.

In an embodiment of network, each A-2 unit 230 is connected to a plurality of LSM240 and a plurality of A-3 unit 250.The highspeed user is connected to A-2 unit 230 by A-3 unit 250, and is connected to A-2 unit 230 based on the narrow-band user of copper cash by LSM240.Fig. 7 generality is described the operation of this network.

In step 710, A-1 unit 220 receives the internet data that is assigned to unique user.In step 720, A-1 unit these data of 220 Route Selection are to the A-2 unit 230 that service is provided as member's regional network to this user.In step 730, A-2 unit 230 receives data.In step 740, the user's that A-2 unit 230 decision data are assigned to identity, and check user's identity according to customer data base.

If the user is the high-speed service user, therefore, be positioned at building with A-3 unit 250, then in step 755, to A-3 unit 250, it provides service for the building at this user place by these data of high-speed line 255 Route Selection in A-2 unit 230.In step 760, A-3 unit 250 receives data.In step 770 and 780, the A-3 unit arrives user's LSM270 by these data of wireless radio transmission circuit Route Selection of this building.

Return step 740, if the user is not the high-speed service user, then in step 745, A-2 unit these data of 230 Route Selection are to LSM240, and it provides service for the building at this user place.In step 750, LSM240 receives data and transmits the LSM270 of these data to the user by the wireless radio transmission circuit.

In another embodiment, when building (as building 235) when highspeed user and low speed user are arranged, all the Internet signal send to the A-3 unit 250 of building from A-2 unit 230.This comprises those signals of the low speed user that is assigned in the building.In this embodiment, LSM unit 270 is 10Base-S unit, and therefore, the Internet signal that A-3 unit 250 directly will be assigned to low speed user sends to their LSM unit 270.

In another alternate embodiment, the A-3 unit is connected to LSM unit (not shown), LSM unit and then be connected to interior of building copper network 145.Then, if send a grouping to low speed user, this is grouped into the LSM that is connected reception of A-3 unit and Route Selection, sends the LSM unit 270 that this is grouped into the user then.In yet another embodiment, the LSM unit that is connected to the A-3 unit can be from LSM unit 240 received signals, and these signals of Route Selection are to the A-3 unit that is connected.This structure has the advantage of redundancy: if break to the optical fiber communication line of A-3 unit, the highspeed user still can use idling slow speed system, and if copper cash (or LSM240) gone bad, low speed user is still accepted Internet service by the A-3 unit.

Though the preferred embodiment with reference to this system and method specifically illustrates and has described the present invention, those skilled in the art will know that, the present invention can be made in form, on the details with different improvement, distortion and the modification implemented, and do not exceed the spirit and scope of the present invention of appended claim definition.

For example, though describe A-1, A-2, A-3, LSM and HSC unit with very concrete part number and configuration here, the function that one skilled in the art will appreciate that each these unit in fact can be by the many different configuration replication of the different assemblies of different manufacturers.

In addition, be used for the wireless radio transmission net, one skilled in the art will appreciate that the present invention also can be used for others though the foregoing description has mainly been described them.For example, common telephone wire also constitutes and can use copper network of the present invention.
