Description
Technical field
The utility model relates to the mobile communication technology field, particularly a kind of vehicle-mounted connecting system based on the LTE technology.
Background technology
In the mobile communications network, no matter be 2G or 3G, under the situation that adopts traditional coverage mode, to business such as the access that is in the mobile subscriber in the high-speed motion and conversations good service can not be provided, this point is particularly evident on high ferro.The climax of building along with Chinese high ferro arrives, and the scale of high-speed railway network is increasing, and train running speed can be more and more faster.
Be accompanied by the raising of the high ferro speed of service; The seal of high ferro railway car also improves thereupon; Train adopts the totally enclosed type body construction; Glass has also adopted metal coating glass, thereby causes the car body penetration loss to increase substantially, and the signal strength signal intensity that mobile phone receives in the compartment is significantly decay thereupon also.And along with the speed of service of high ferro train from 300 kilometers/hour to 400 kilometers/hour even 500 kilometers/hour; The lifting of speed causes the user frequently to be switched, when switching, also can cause a large amount of signaling transmission at network side; Cause so-called signaling storm; Thereby the problem that the user connects, handover success rate reduces occurs, the user experiences variation.
In order to solve the problem of above-mentioned high ferro communication; Stable, broadband and communication service reliably are provided between the car ground; There is company to propose (Long Term Evolution based on LTE; Long Term Evolution) high-speed railway LTE cell on wheels scheme is to realize HRC (High-Speed Railway Communication) end-to-end solution.Through using the state-of-the-art LTE of present industry technology, with HRC Vehicle mounted station allocating antenna in the compartment outer end, in the compartment, Vehicle mounted station converges, distributes Abis, the Iub interface data of vehicle-mounted 2G/3G base station equipment; High ferro passenger inserts the 2G/3G network through integrated access equipment in the compartment, in train travelling process, does not only have car body loss problem, does not also have the minizone to switch, and does not more exist the crowd to move the signaling storm problem that causes.
But still have a problem when adopting said method, promptly when high ferro fast through out-of-date, the frequency that the frequency of cell on wheels can be to other macro base stations, especially be near the macro base station the station, city is brought interference, increases the network planning design difficulty of high ferro networking.And because the high-speed cruising of train, also increasingly high to the requirement of the size of top antenna, antenna size is big more, and windage also can be big more during high-speed motion, causes train when high-speed motion, to have bigger potential safety hazard.
The utility model content
To the problem that exists in the above-mentioned prior art, the purpose of the utility model is to provide a kind of vehicle-mounted connecting system based on the LTE technology, and the frequency that can effectively solve cell on wheels is to the interference of railway co-frequency cell on the way and the problem of traffic safety.
A kind of vehicle-mounted connecting system based on LTE comprises:
Receive the up-link wireless signal in the compartment and handle to become and send to said vehicle-mounted LTE Transmit-Receive Unit behind the upstream data, receive downlink data that said vehicle-mounted LTE Transmit-Receive Unit sends and processing and become the cell on wheels that sends to subscriber equipment after the downstream wireless signals;
Descending LTE standard signal after receiving said upstream data and after LTE standard treatment conversion becomes up LTE standard signal, sending to vehicle-mounted microwave transmitting and receiving unit, receiving demodulation is also handled the vehicle-mounted LTE Transmit-Receive Unit that sends to said cell on wheels after becoming downlink data through the LTE standard;
Send to the vehicle-mounted microwave transmitting and receiving unit of said vehicle-mounted LTE Transmit-Receive Unit after outwards sending, receive descending microwave signal and be demodulated to descending LTE standard signal after receiving said up LTE standard signal and being modulated to up microwave signal.
Can find out from above scheme; The vehicle-mounted connecting system based on LTE of the utility model; Owing to utilized microwave as wireless signal transmission; When high ferro or other equipment that use native system during fast through the somewhere, the frequency of cell on wheels can not brought interference to the frequency of other macro base stations (near the especially macro base station the railway station), has greatly reduced the network planning design difficulty of high ferro networking; And because the frequency of microwave is high, so the antenna size than traditional LTE frequency range is little on the size design of top antenna, the windage when having reduced the train high-speed cruising, the fail safe that has improved bullet train also helps train and installs.
