Abstract
The utility model discloses a nine-inlet-one-outlet combining system for mobile communication. The system includes an uplink system and a downlink system, integrates all communication signals of current mobile communication systems in China, further introduces 3G and analog trunking signals, and can reserve physical interfaces for a 3G network (WCDMA, CDMA2000 and TD-SCDMA). Through transmission by a platform system of the utility model, interference among various communication systems can be effectively avoided to enable more strengthened and clearer communication signals. The nine-inlet-one-outlet combining system is primarily used in large venues and municipal facilities with multi-network system access. The nine-inlet-one-outlet combining system achieves a multi-band, multi-signal combining function, avoids overlapping investment in indoor distribution system construction, and is an effective scheme for achieving multi-network signal compatible coverage.
Description
Technical field
The utility model relates to the network optimization product in a kind of electronic information and mobile communication technology field, particularly a kind of nine Jin Yichuhe road systems.
Background technology
Nowadays no matter oneself,, through very universal, be that the systems such as GSM or CDMA or LTE, DCS, WCDMA have all spreaded all over each place that Chinese population is intensive a little to mobile communication system.These systems are all set up separately and operated by different companies, and the business of intercommunication is also provided between separately.But in some special occasion, the network of multiple types communication system all cannot effectively cover, now just need a platform that the signal of communication of variety of network systems is all collected, and then by these signals respectively with separately under system get in touch with, this be just equivalent between foundation a terminal.This system as terminal is sought after in many occasions, such as subway is exactly the occasion of typical case's application.People are in the tunnel of subway, and platform needs the Mobile Communication Service of various standards in the compartment of subway concourse and subway, and the digital television signal in subway, cluster signal are also introduced into region on the ground in addition.Along with the development of subway industry and universal, the demand of described system also can be increasing, thereby this broadband multisystem mixing system is subject to the attention of relevant department.In addition, this system not only can extensive use in subway, and also has wide practical use at park, conference centre etc.Broadband multisystem mixing system provides mobile network's service for user, and this not only has certain economic implications, and has far-reaching social effect.But at present, in this area, still there is not such multisystem mixing system.
Utility model content
The utility model is newly for solving the descending road of closing of the systems such as CDMA, GSM, DCS, WCDMA, LTE, 3G and cluster, and the problem of up shunt, provides one kind of multiple standard communication system integration road systems.
A kind of nine Jin Yichuhe road systems that the utility model provides comprise up-link and downlink system, and described up-link comprises nine signal ports, a tri-frequency combiner, three duplexers, two isolators, an electric bridge and five frequency combiners.Described, telecommunications CDMA port, mobile TD(B) port, mobile LTE port be directly connected with the input port of five frequency combiners.Mobile DCS port, mobile TD(F) port, the LTE of UNICOM port be connected to the input port of five frequency combiners by tri-frequency combiner.First, second telecommunications LTE is connected to the input port of first duplexer, and first duplexer is connected to the input port of five frequency combiners again by electric bridge.UNICOM's WCDMA port is connected to the input port of the second duplexer, and the second duplexer is connected to the input port of the 3rd duplexer again by first, second isolator arranged side by side, and the 3rd duplexer is connected to the input port of five frequency combiners again by electric bridge.Downlink system is identical with up-link structure, is only that signal transfer direction is contrary.
Described electric bridge is 3dB electric bridge.
The utility model comprises the input of multiple types communication system and multiple types communication system output system, it has introduced multiple mobile network system signal, integrated the signal of communication of Chinese at present all mobile communication system, can also introduce 3G and simulation cluster signal, and can be for the reserved physical interface of 3G net (WCDMA, CDMA2000, TD-SCDMA).Through the transmission of the utility model plateform system, can effectively avoid the interference between each communication system, signal of communication is strengthened and clear more.Be mainly used in, in the large-scale place, urban operating mechanism of multiple-network system access, having realized multiband, many signals close road function, and the overlapping investment of having avoided indoor distributed system to build is a kind ofly to realize that many network signals are compatible covers effective scheme.
Accompanying drawing explanation
Fig. 1 is up-link structural representation.
Embodiment
As shown in Figure 1, the utility model comprises up-link and downlink system, and described up-link comprises nine signal ports 1 ~ 9, tri-frequency combiner 11, three 15,16,3dB electric bridges 17 of 12,13,14, two isolators of duplexer and five frequency combiners 18.Described, telecommunications CDMA port one, mobile TD(B) port 8, mobile LTE port 9 be directly connected with the input port of five frequency combiners 18.Mobile DCS port 2, mobile TDF port 3, the LTE of UNICOM port 4 are connected to the input port of five frequency combiners 18 by tri-frequency combiner 11.First, second telecommunications LTE5,6 is connected to the input port of first duplexer 12, and first duplexer 12 is connected to the input port of five frequency combiners 18 again by 3dB electric bridge 17.The WCDMA of UNICOM port 7 is connected to the input port of the second duplexer 13, the second duplexer 13 is connected to the input port of the 3rd duplexer 14 again by first, second isolator 15,16 arranged side by side, the 3rd duplexer 14 is connected to the input port of five frequency combiners 18 again by 3dB electric bridge 17, finally by output 10 outputs.Downlink system is identical with up-link structure, is only that signal transfer direction is contrary.
The concrete application approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
