The present invention relates to supporting a handover of a mobile terminal. Preferably, the present invention performs a scan of a neighboring network different from a current network of the mobile terminal to determine the presence of an accessible link of the neighboring network for performing a handover, wherein the mobile terminal comprises a heterogeneous network handover module that 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. An information message is then received from the neighboring network, wherein the information message comprises an information element associated with whether the neighboring network is capable of communicating with the heterogeneous network handover module of the mobile terminal.

What is claimed is: 1. A method of data communication in a mobile terminal for supporting a handover of the mobile terminal, the method comprising: transmitting to a base station a request message comprising media independent handover (MIH) capability information which indicates whether the mobile
What is claimed is: 1. A method of data communication in a mobile terminal for supporting a handover of the mobile terminal, the method comprising: transmitting to a base station a request message comprising media independent handover (MIH) capability information which indicates whether the mobile terminal supports an MIH function associated with handover between heterogeneous networks and a first indicator indicating whether the mobile terminal supports an information service, the request message transmitted during an initial network entry procedure for capability negotiation with the base station; and receiving from the base station a response message in response to the request message, the response message comprising media independent handover (MIH) capability information which indicates whether the base station supports an MIH function associated with handover between the heterogeneous networks, the response message received during the initial network entry procedure for the capability negotiation. 2. The method of claim 1, wherein the request message is a basic capability request (SBC-REQ) message and the response message is a basic capability response (SBC-RSP) message. 3. The method of claim 1, wherein the request message further comprises at least one of a second indicator indicating whether the mobile terminal supports an event service and a third indicator indicating whether the mobile terminal supports a command service. 4. The method of claim 1, wherein the response message further comprises at least one of a first indicator indicating whether the base station supports an information service, a second indicator indicating whether the base station supports an event service and a third indicator indicating whether the base station supports a command service. 5. The method of claim 1, wherein the request message further comprises information about a type of MIH service supported by the MIH function of the mobile terminal. 6. The method of claim 1, wherein the response message further comprises information about a type of MIH service supported by the MIH function of the base station. 7. A method of data communication at a base station for supporting a handover of a mobile terminal, the method comprising: receiving from the mobile terminal a request message comprising media independent handover (MIH) capability information which indicates whether the mobile terminal supports an MIH function associated with handover between heterogeneous networks and a first indicator indicating whether the mobile terminal supports an information service, the request message received during an initial network entry procedure for capability negotiation with the base station; and transmitting to the mobile terminal a response message in response to the request message, the response message comprising media independent handover (MIH) capability information which indicates whether the base station supports an MIH function associated with handover between the heterogeneous networks, the response message transmitted during the initial network entry procedure for the capability negotiation. 8. The method of claim 7, wherein if the base station supports the MIH function then the mobile terminal communicates with the base station using a medium access control management message. 9. The method of claim 7, further comprising: receiving a scan request from the mobile terminal through a broadband wireless access network interface prior to receiving the request message. 10. The method of claim 7, wherein the response message is transmitted through a medium access control of the broadband wireless access network interface. 11. The method of claim 7, wherein the response message further comprises at least one of an information service support indicator, an event service support indicator and a command service support indicator. 12. The method of claim 7, wherein the response message is one of a broadcast message, a frame check header message, a registration response message, a subscriber station basic capability response message, and a neighbor base station broadcast message. 13. The method of claim 7, wherein the request message further comprises at least one of a second indicator indicating whether the mobile terminal supports an event service and a third indicator indicating whether the mobile terminal supports a command service. 14. The method of claim 7, wherein the request message further comprises information about a type of MIH service supported by the MIH function of the mobile terminal. 15. The method of claim 7, wherein the response message further comprises information about a type of MIH service supported by the MIH function of the base station. 16. A mobile terminal supporting a media independent handover, the mobile terminal comprising: a transmitter for transmitting to a base station a request message comprising media independent handover (MIH) capability information which indicates whether the mobile terminal supports an MIH function associated with handover between heterogeneous networks and a first indicator indicating whether the mobile terminal supports an information service, the request message transmitted during an initial network entry procedure for capability negotiation with the base station; and a receiver for receiving from the base station a response message in response to the request message, the response message comprising media independent handover (MIH) capability information which indicates whether the base station supports an MIH function associated with handover between the heterogeneous networks, the response message received during the initial network entry procedure for the capability negotiation.
