Patent ID: 8036673

Claim:
A status notification method in a wireless communication apparatus for performing wireless communication with a wireless terminal, the status notification method comprising the steps of: the wireless communication apparatus receiving a QoS start request containing an upstream QoS identifier and a downstream QoS identifier from the wireless terminal; executing a first upstream noise determination by comparing a current noise level Ns of upstream traffic noise measured in the wireless communication apparatus with a permissible noise level ShN to start QoS, corresponding to the upstream QoS identifier and, if Ns<ShN, determining that upstream QoS can be accepted; executing a first downstream band determination by comparing a band B obtained by subtracting a QoS occupied band from the entire downstream band BW, with a band R required to start QoS, corresponding to the downstream QoS identifier and, if B>R, determining that downstream QoS can be accepted; executing a first QoS acceptance determination to determine that it is serviceable if both the first upstream noise determination and the first downstream band determination indicate that it is serviceable; adding the downstream QoS identifier corresponding to the wireless terminal to an occupied QoS table if the first QoS acceptance determination indicates that it is serviceable; sending a QoS start acknowledgment to the wireless terminal; executing a second upstream noise determination by comparing the current noise level Ns of the upstream traffic noise measured by an upstream traffic reception block of the wireless communication apparatus with the permissible noise level ShN to start QoS, predetermined for VoIP or another specific service and corresponding to an upstream QoS identifier setting, and if N<ShN, determining that upstream QoS can be accepted; executing a second downstream band determination by comparing the band B obtained by subtracting the QoS occupied band obtained from the occupied QoS table updated when the downstream QoS identifier is added to the table, from the entire downstream band BW, with the band R required to start QoS, predetermined for VoIP or another specific service and corresponding to a downstream QoS identifier setting, and if B>R, determining that downstream QoS can be accepted; executing a second QoS acceptance determination to determine that it is serviceable if both the second upstream noise determination and the second downstream band determination indicate that it is serviceable; broadcasting first channel congestion information in an area of the wireless communication apparatus if the second QoS acceptance determination indicates that it is not serviceable; and the wireless terminal in a communication area of the wireless communication apparatus displaying information notifying the user of the occurrence of congestion on a display screen when it receives the first channel congestion information.
