A method of transmitting messages for acquisition of information related to a specific network entity or a link network during network selection in a mobile terminal is disclosed. The method of transmitting messages for acquisition of information related to a network entity or a link network during network selection in a mobile terminal comprises generating, in an upper management entity, a first primitive for requesting information related to the network entity or the link network through an access point (AP), delivering the first primitive to a media access control (MAC) layer, transmitting a first request message including contents of the first primitive to the access point to request the information, receiving a second response message from the access point, the second response message including information related to the specific network entity or the link network, and delivering a third primitive from the MAC layer to the upper management entity, the third primitive including contents of the second response message.
