PURPOSE: To attain the call reception independently of a numbering system of a station of a mobile destination even when a mobile radio terminal equipment (PS) makes roaming. CONSTITUTION: When roaming takes place in a PS 9, a visitor private branch exchange station (WLPBX) 14 acquires an extension number not in use as its own extension number, then the PS 9 is integrated in the numbering system of the WLPBX 14 and the acquired extension number is reported to a home WLPBX 13. Thus, at the reception of a call, current station information of a call reception PS and an extension number acquired by the PS in the visitor WLPBX are recognized based on home station information and visitor station information to allow the PS to receive the call. |
