PROBLEM TO BE SOLVED: To receive a service from a public network even when a radio terminal in an indoor mode by reading an indoor terminal identification number corresponding to a public terminal identification number and allowing an indoor mode radio terminal of call-incoming destination to receive by this number. SOLUTION: The public radio base station CS1 or a public radio service network stars authentifying processing to a position registering request and sends and authentication request signal to an indoor radio base station 12. The station informs a radio terminal PS1 of an authentication random number and at the time of receiving an arithmetic result obtained from the algorithm from the terminal PS1, returns it to the side of the station CS1 again. The station CS1 or the public radio service network compare-verifies this arithmetic result and informs the terminal PS1 of the result by mounting on a position registering response. In addition, the station 12 converts the terminal identifying number and converts a public wave to an indoor wave each time of relaying a signal.
