Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] The following description and drawings illustrate specific embodiments of the invention sufficiently to enable those skilled in the art to understand and practice them.

[0020] Such as figure 1 As shown, the vehicle-mounted base station mobile communication system for high-speed railways includes a vehicle-mounted base station installed inside the train, antennas distributed inside the train, a phased array antenna 101 outside the vehicle, and ground base stations 102 distributed along the rail. The vehicle-mounted base station is connected to the antenna inside and outside the vehicle through corresponding cables.

[0021] The working principle of the vehicle-mounted base station mobile communication system is as follows: in the uplink, the vehicle-mounted base station 103 uses the antenna 104 distributed in each compartment to receive the sig...

Abstract

The invention discloses a train-mounted base station mobile communication system for high speed railways. The train-mounted base station mobile communication system for high speed railways comprises a train-mounted base station, a train internal antenna, a train external phased-array antenna and a ground base station. The train-mounted base station is communicated with the inside user through the train internal antenna and is connected wirelessly with the ground base station through the train external phased-array antenna. Each array of the train external phased-array antenna is adjustable, so that a main lobe beam that always points to the ground base station can be formed. According to the invention, the main lobe beam of the phased-array can always point to the ground base station through adjusting the phase of the antenna array, the effect that the signal strength received by the train base station is the higher can be ensured, and the communication quality of the users on the train can be improved.

Description

technical field [0001] The invention relates to a mobile communication system, in particular to a vehicle-mounted base station mobile communication system for high-speed railways. Background technique [0002] With the development of information technology, people's life and work need to use mobile phones all the time. Therefore, high-quality signal coverage is also required on high-speed trains. But in fact, signal coverage on high-speed rail has always been problematic due to interference from various factors, such as Doppler frequency shift, multipath interference, shielding of train carriages, complex terrain, and handoffs. Various factors will lead to insufficient signal strength or unstable signal in the train. The direct result is poor communication quality and reduced user experience. Contents of the invention [0003] In view of this, the object of the present invention is to provide a vehicle-mounted base station mobile communication system for high-speed railw...
