High-speed railway is one of the window scenes of 4 G/5 G wireless network

with a high density of VIP users and continuous growth in recent years. With the construction of 5 G

the wireless network structure is more and more complex. Due to the diversity of coverage scenarios

the difference of equipment capacity of each manufacturer

the existing public network networking structure and the operation of frequency reversal

there are abundant frequency con? guration schemes in the high-speed railway private network. Aiming at the differences of high-speed railway private network and problems of the traditional "one size fits all" capacity assessment method

this paper proposes a capacity assessment scheme for high-speed railway private network based on multiple frequency configuration scheme

which could effectively evaluate the load variation of high-speed railway network in different scenarios. Through application

this method is proved to be an efficient way to guarantee capacity

improve customer perception and promote traf? c growth.
