The present invention relates to performing handover of a mobile terminal to a network. Preferably, the present invention generates a first heterogeneous protocol message from a heterogeneous network handover module to a medium access control (MAC) of the mobile terminal, wherein the heterogeneous network handover module is configured to provide convergence of information from at least one network interface module associated with one of a homogeneous and heterogeneous network into a unified presentation. A management request associated with a handover process is then transmitted to a serving network, wherein the management request comprises the first heterogeneous protocol message. Accordingly, messages can be remotely exchanged via a radio section between heterogeneous network handover modules of a mobile terminal and a serving network. Therefore, messages are transferred faster and media independent handover is performed more quickly.

A method of associating a mobile station to a base station in a wireless communication system comprises transmitting to a serving base station a scanning request message comprising an association indicator. The method also comprises receiving from the serving base station a scanning response message comprising a rendezvous time associated with a neighboring base station for initiating ranging with the neighboring base station, wherein the serving base station communicates an association notification to the neighboring base station, the association notification comprising the rendezvous time. The method also comprises associating with the neighboring base neighboring base station by transmitting a ranging request after passing of the rendezvous time determined from a transmission time of the scanning response message from the neighboring base station, wherein the rendezvous time is associated with a time the neighboring base station is expected to provide a non-contention based ranging opportunity for the mobile station.

The method also comprises, if the decode information change status indicates a change in the decode information, maintaining the idle mode, and receiving the decode information from the at least one base station when the transmission frame value is reached. The decode information may comprise at least one of downlink channel descriptor (DCD) information, uplink channel descriptor (UCD) information, and forward error correction (FEC) code type information. The transmission frame value may comprise a frame number or a frame offset. The at least one base station may be in a same paging group.
