摘要：
As a frequency resource limited system, frequency planning is one of the key points that determine the application quality and operation efficiency of the GSM-R system. With the gradual expansion of the construction scale, the traditional frequency planning and allocation principles can no longer guide the engineering practice and operation and maintenance of the GSM-R system. In order to satisfy the needs of railway transportation organization and maximize frequency resource efficiency, based on technical features of GSM-R system and the existing GSM-R system wireless channel resource estimation method, a new method of wireless channel resource estimation for GSM-R systemwas proposed, based on railway application scenarios. The results show that this method can be better used to optimize the frequency resource allocation of GSM-R base station cell. Compared with traditional communication traffic estimation methods, this method is more consistent with the characteristics of railway applications. © 2021, Department of Journal of the China Railway Society.
