System and method for monitoring quality of service in a broadband wireless network

A system for monitoring Quality of Service (QoS) in a broadband wireless network, comprising:

• a QoS memory for storing QoS information received in real time from base stations having synchronized time information;
• a control unit responsive to a wireless terminal in a service zone of a first base station requesting to be handed off to a second base station, for examining QoS information of the second base station stored in the QoS memory to determine whether a service level the same as QoS information of a first base station is available from the second base station;
• and
• a QoS level determiner for determining a QoS level in the second base station according to a result of the determination by the control unit.

A method for monitoring Quality of Service (QoS) in a broadband wireless network, the method comprising the steps of:

• (a) receiving and monitoring QoS information in real time from base stations having synchronized time information;
• (b) when a wireless terminal in a service zone of a first base station requests to be handed off to a second base station, determining a QoS level according to QoS information of the second base station;
• and
• (c) transmitting the QoS level simultaneously to the first and second base stations.

A method for monitoring Quality of Service (QoS) in a broadband wireless network, the method comprising steps of:

• (a) receiving, at a first base station, a handoff request signal from a wireless terminal, and transmitting a handoff pre-notification signal simultaneously to a QoS monitoring server and a second base station;
• (b) examining, at the QoS monitoring server, QoS information received in real time from the first and second base stations, determining a QoS level, and transmitting the QoS level simultaneously to the first and second base stations;
• and
• (c) transmitting the QoS level from the first base station to the wireless terminal, handing the wireless terminal off to a cell zone of the second base station from a cell zone of the first base station, and providing a service according to the QoS level provided to the wireless terminal by the second base station.
