Apparatus and method for obtaining information on neighbor network for vertical handover in a wireless communication system

摘要

A wireless communication system supporting Media Independent Handover (MIH) is provided. The system comprises an MIH Function (MIHF) for receiving an MIH query message requesting Layer-2 (L2) information from an MIHF of a neighbor network, and extracting the contents of the query from the MIH query message, a converter for transmitting a network specific request message which contains the contents of the query, and a point of attachment (PoA) for providing the L2 information which is requested by the network specific request message.
