1. A wireless access system comprising:
- a plurality of wireless base stations connected to a backbone network;
a subscriber station connected to said wireless base station via a wireless circuit; and
a management center for performing management of said network, said management center being provided with an SNMP manager, said each wireless base station being provided with an SNMP agent and a subscriber management information table for storing subscriber information, said each wireless base station referring to said subscriber management information table to perform communication with the subscriber station permitted to communicate, wherein the SNMP manager of said management center uses an SNMP protocol to transmit information of subscriber new registration to the SNMP agent of said wireless base station in accordance with an SNMP SET request, and the SNMP agent of said wireless base station checks whether or not a pertinent subscriber is registered in said subscriber management information table on judging that said SET request is the subscriber new registration, returns an error to the SNMP manager of said management center when the subscriber is already registered, and registers the information of the subscriber of the new registration in said subscriber management information table when the subscriber is not registered.
