Apparatus and method for processing vertical handoff in a wireless communication system

摘要

An apparatus and method for processing a vertical handoff between a WLAN and a broadband wireless communication network are provided. In a method of processing a vertical handoff in a handoff processor having a mapping table in which QoS information for the broadband wireless communication network is mapped to QoS information for the WLAN, QoS information about an STA received from a source network is converted to QoS information suitable for a target network, referring to the mapping table. A message containing the converted QoS information is generated and sent to the target network.
