BANDWIDTH CONTROL SYSTEM
First Claim
1. A bandwidth control system, comprising,a base station provided in a first wireless system,a relay device for relaying a preliminary authentication request transmitted from a second wireless system to the base station, anda bandwidth control device for controlling a bandwidth of a communication path for relaying the preliminary request from the second wireless system to the base station, wherein,the base station comprises,a local authentication information holder for storing identification information of a wireless terminal being successful in authentication, among the wireless terminals authenticated by the base station through wireless communication,a preliminary authentication information holder for storing identification information of the wireless terminal being successful in preliminary authentication, based on the preliminary authentication request received via the relay device, anda band limiting indicator for transmitting to the bandwidth control device, a band limiting instruction to limit a bandwidth of the communication path for relaying the preliminary authentication request from the second wireless system to the base station, in the case where a predetermined relationship is established between a local authentication count corresponding to a count of the identification information of the wireless terminal held by the local authentication information holder, and a preliminary authentication count corresponding to a count of the identification information of the wireless terminal held by the preliminary authentication information holder,the bandwidth control device instructs the relay device to limit the bandwidth of the communication path for relaying the preliminary authentication request from the second wireless system to the base station, upon receipt of the band limiting instruction from the base station, andthe relay device limits the bandwidth of the communication path, upon receipt of the instruction from the bandwidth control device, to limit the bandwidth of the communication path for relaying the preliminary authentication request from the second wireless system to the base station.

Abstract
A bandwidth control system is provided, enabling the prevention of a resource shortage in the base station, caused by preliminary authentication which reserves resources in advance. The bandwidth control system limits a bandwidth of a communication path used for the preliminary authentication, in the case where a count of successful authentication of the wireless terminal belonging to the first wireless system and a count of successful preliminary authentication transmitted from the wireless terminal belonging to the second wireless system establish a predetermined relationship.
