Patent ID: 8418228

Claim:
A QoS (Quality of Service) control method using a network access device at an edge node of an IP network of a convergence ALL-IP network, the QoS control method comprising: controlling, by the network access device, QoS of downlink traffic on the basis of the amount of radio resources allocated, wherein the controlling of the QoS of the downlink traffic comprises: acquiring the amount of radio resources allocated by a wireless access device provided in a wireless subscriber network to which the downlink traffic will be transferred; comparing the amount of radio resources allocated with a data amount of the downlink traffic; and performing scheduling and shaping of guaranteed downlink traffic at each service session and performing rate shaping of non-guaranteed downlink traffic according to the amount of wireless bandwidth allocated when the data amount of the downlink traffic exceeds the amount of radio resources; and controlling, by the network access device, controlling QoS of uplink traffic according to bandwidth information acquirable from call control signaling or a service-specific resource allocation policy.
