Abstract
The invention discloses a gateway applied to a radio and television network, particularly the gateway capable of combining broadband and narrowband in the radio and television network. A high-pass module, a low-pass module and a band-pass module transmit received narrowband data to a narrowband receiving processing module, and transmit broadband data to a broadband receiving processing module. The narrowband receiving processing module and the broadband receiving processing module receive and process the data, and transmit the processed data to a server. The server transmits response data to the narrowband receiving processing module and the broadband receiving processing module respectively. The narrowband receiving processing module transmits the response data to an edge modulator by a downlink forwarding module after receiving the response data. The broadband receiving processing module transmits the response data to the high-pass, low-pass and band-pass modules after receiving the response data from the edge modulator. The gateway has the advantages of not transforming the conventional network, satisfying various needs of equipment in uplink and downlink data transmission, realizing a demand assignment network, reducing the fulfilling cost and increasing the coverage rate of the broadband.
Description
Technical field
The present invention relates to a kind of gateway that is applied to CHINA RFTCOM Co Ltd, be specifically related to a kind of can be with the gateway of the broadband in the CHINA RFTCOM Co Ltd and arrowband unification.
Background technology
At present, mainly contain two kinds of CHINA RFTCOM Co Ltd bidirectional rebuilding technology on the market, a kind of is centralized CMTS system, the local side of this system is placed on very front end, though its area coverage is bigger, but the noise that exists funneling effect promptly to converge is very big, another kind is that the EOC technology is to carry out the transmission of Ethernet data signal in the coaxial cable, mainly be through in coaxial cable, carrying out transfer of data after the ovennodulation with ethernet signal, its frequency does not take cable TV frequency band and cable TV frequency coexistence, but its broadband local side is single, terminal Costco Wholesale height can't be popularized widely.
Summary of the invention
The object of the present invention is to provide a kind of gateway that is applied to CHINA RFTCOM Co Ltd, solve prior art arrangement cost height, can't make full use of existing network broadband problem of resource.
For addressing the above problem, the technical solution used in the present invention is:
A kind of gateway that is applied to CHINA RFTCOM Co Ltd, comprise high pass, low pass, the logical module of band, the narrow-band reception processing module, the broadband reception processing module, descending forwarding module and edge modulator, high pass wherein, low pass, the logical module of band will receive narrow band data and be transferred to the narrow-band reception processing module, the broadband reception processing module is given in broadband data transmission, narrow-band reception processing module and broadband reception processing module are transferred to server after receiving data and processing, server sends reply data and is transferred to narrow-band reception processing module and broadband reception processing module respectively, the narrow-band reception processing module is transmitted edge modulator by descending forwarding module after receiving reply data, and the edge modulator is being given high pass transfer of data, low pass, the logical module of band.
Further technical scheme is: also be provided with the webmaster module of the whole network of management, can manage whole gateway system by this webmaster module.
Further technical scheme is: the broadband band signal is below 33M, and narrow band signal is more than 915M, and 47M is the digital television signal data to the data between the 860M, though each signal frequently mixes like this, does not influence each other.
Further technical scheme is: above-mentioned descending forwarding module is that the arrowband Ethernet data that will receive is transmitted to edge debugger (IPQAM).Edge modulator (IPQAM) giving terminal data forwarding.
Adopt the beneficial effect that technique scheme produced to be: to need not existing network is transformed, and this gateway not only can satisfy the device requirement for up-downgoing data demand symmetry, it is little to satisfy upstream data, the device requirement that downlink data is big, realized the distribution according to need network bandwidth, reduced and opened cost, improved the coverage rate in broadband.

Fig. 1 is a principle of the invention block diagram.
Embodiment
Following the present invention does and describes in further detail:
As shown in Figure 1: a kind of gateway that is applied to CHINA RFTCOM Co Ltd, comprise high pass, low pass, the logical module of band, the narrow-band reception processing module, the broadband reception processing module, descending forwarding module and edge modulator, high pass wherein, low pass, the logical module of band will receive narrow band data and be transferred to the narrow-band reception processing module, the broadband reception processing module is given in broadband data transmission, narrow-band reception processing module and broadband reception processing module are transferred to server after receiving data and processing, server sends reply data and is transferred to narrow-band reception processing module and broadband reception processing module respectively, the narrow-band reception processing module is transferred to edge modulator (IPQAM) by descending forwarding module after receiving reply data, and the edge modulator (IPQAM) giving high pass transfer of data, low pass, the logical module of band.In the technical program, also be provided with the webmaster module of the whole network of management, can manage whole gateway system by this webmaster module; Broadband signal is below 33M, and narrow band signal is more than 915M, and 47M is the digital television signal data to the data between the 860M, though each signal frequently mixes like this, does not influence each other.The present invention need not existing network is transformed, and this gateway not only can satisfy the device requirement for up-downgoing data demand symmetry, and it is little to satisfy upstream data, the device requirement that downlink data is big, reduced and opened cost, improved the coverage rate in broadband.
The present invention in actual applications, the logical module effect of high pass, low pass, band is narrow radio frequency signal, broadband rf signal and the cable TV signal that separates on the CHINA RFTCOM Co Ltd; The effect of broadband reception module is the conversion of finishing broadband rf signal and ethernet signal; The effect of narrow-band reception module is that the up narrow radio frequency signal of receiving terminal converts up radiofrequency signal to up ethernet signal; The forwarding module effect is the reply data that receives the arrowband from Ethernet, then reply data is transmitted to edge modulator (IPQAM); The webmaster module, the monitoring management whole system guarantees the true(-)running of system.
Claims (4)
1. gateway that is applied to CHINA RFTCOM Co Ltd, it is characterized in that: comprise high pass, low pass, the logical module of band, the narrow-band reception processing module, the broadband reception processing module, descending forwarding module and edge modulator, high pass wherein, low pass, the logical module of band will receive narrow band data and be transferred to the narrow-band reception processing module, the broadband reception processing module is given in broadband data transmission, narrow-band reception processing module and broadband reception processing module are transferred to server after receiving data and processing, server sends reply data and is transferred to narrow-band reception processing module and broadband reception processing module respectively, the narrow-band reception processing module is transferred to edge modulator by descending forwarding module after receiving reply data, and edge modulator is transferred to high pass again, low pass, the logical module of band.
