ABSTRACT:
A technology of detecting MIHP information before an OSI layer 3 process is performed. A method of performing Media Independent Handover (MIH) includes analyzing a field for indicating Internet Protocol (IP) version information, if a value of the field for indicating IP version information corresponds to an MIH layer, performing a process of the MIH layer and performing a process of an IP layer, and if a value of the field for indicating IP version information does not correspond to the MIH layer, directly performing the process of the IP layer. Accordingly, an IP layer that is the third layer of the OSI 7 layers can determine without performing a separate operation whether an MIH process is performed. Thus, a delay of a processing speed of a device can be prevented, resulting in an increase of QoS of a network.
