Dedicated random access resource preservation method and base station

The invention provides a method of specialized random access resource reservation. In the method, the required time of the terminal random access failure is estimated, and according to the required time of the terminal random access failure, the reserved period of specialized random access resources is determined; when the random access process is triggered, the base station distributes specialized random access resources for the terminal according to the reserved period. The invention simultaneously provides a base station for realizing the specialized random access resource reservation, and the method and the base station can avoid unnecessary specialized random access resource reservation and improves the utilization rate of the specialized random access resources.
