PROBLEM TO BE SOLVED: To provide a private branch radio communication system capable of displaying a fault or the like relating to the position registration of a terminal station. SOLUTION: A display device 50 is provided with a means for storing the position registration request message reception time outputted from a management station device 40 and comparing the position registration request message reception time outputted from the management station device 40 next with the stored position registration request message reception time. Thus, in the case that the position registration request message reception time compared by a comparison means 53 is the same, it is displayed that position registration is not completed at the display device 50. |
