[0055] The present invention will be described in detail below in conjunction with the drawings.
[0056] figure 1 It is a schematic diagram of the LTE cell reselection in the high-speed railway scene of the present invention. According to the linear distribution of the high-speed railway, the mobile communication network along the high-speed railway adopts chain-shaped dedicated cell coverage. In order to reduce the number of reselections, the baseband unit + distribution of BBU+RRU is used The deployment method of the remote radio unit. Generally, 3 physical sites share a cell, so a cell reselection process is generally performed every three physical sites. According to the distribution of high-speed railways and the direction of vehicles, the signals within the high-speed railways require multiple cell reselections.
[0057] Such as figure 2 As shown, the base station device 1 provided by the embodiment of the present invention includes:
[0058] The receiving unit 3 is used f...
