Abstract The new equation of state density is obtained by the utilization of the generalized uncertainty relation. With the help of coordinates and the Wentzel--Kramers--Brillouin approximation, direct calculation of the scalar field entropy of the non-state black hole with an internal global monopole is performed. The entropy obtained from the calculation is proportional to the horizon area. The calculation can be free from convergence if without any cutoff, which is different from the brick-wall method. However, the pertinent result is limited.
