Abstract

An Internet Protocol (IP) address acquisition in a broadband wireless communication system is disclosed. A terminal includes a driver for loading one of a plurality Media Access Control (MAC) addresses for a multi-Frequency Allocation (FA) connection when the terminal is initialized; an interface for registering the loaded MAC address to use in an upper layer of a MAC layer; and a manager for acquiring an IP address using the registered MAC address when a network entry for at least one FA is complete.

Claims

1. A terminal in a wireless communication system, comprising:

a driver for loading one of a plurality of Media Access Control (MAC) addresses for a multi-Frequency Allocation (FA) connection when the terminal is initialized;

an interface for registering the loaded MAC address to use in an upper layer of a MAC layer; and

a manager for acquiring an Internet Protocol (IP) address using the registered MAC address when a network entry for at least one FA is complete.

2. The terminal of claim 1, wherein the one MAC address is preset as a default MAC address.

3. The terminal of claim 1, wherein the interface performs an interfacing operation according to a Network Driver Interface Specification (NDIS).

4. The terminal of claim 1, wherein the manager acquires the IP address according to one of a Dynamic Host Configuration Protocol (DHCP) and a mobile IP protocol.

5. The terminal of claim 1, further comprising:

a plurality of authentication modules for performing a user authentication and an encryption for a corresponding at least one FA in the network entry.

6. The terminal of claim 5, wherein the authentication modules perform authentication according to an Extensible Authentication Protocol (EAP).

7. The terminal of claim 1, further comprising:

a controller for distributing packets generated using the IP address to a plurality of FAs;

a plurality of processors for receiving a classified packet and performing a MAC layer processing on the packet for a corresponding FA; and

a plurality of communicators for converting a bit stream provided from the processors to a signal, up-converting the signal to a band of the corresponding FA, and transmitting the signal.

8. A communication method of a terminal in a wireless communication system, the method comprising:

loading one of a plurality of Media Access Control (MAC) addresses for a multi-Frequency Allocation (FA) connection when the terminal is initialized;

registering the loaded MAC address to use the MAC address in an upper layer of a MAC layer; and

acquiring an Internet Protocol (IP) address using the registered MAC address when a network entry for at least one FA is complete.

9. The communication method of claim 8, wherein the one MAC address is preset as a default MAC address.

10. The communication method of claim 8, wherein the registering of the MAC address to be used in the upper layer is one of interfacing operations according to a Network Driver Interface Specification (NDIS).

11. The communication method of claim 8, wherein the IP address is acquired according to one of a Dynamic Host Configuration Protocol (DHCP) and a mobile IP protocol.

12. The communication method of claim 8, further comprising:

performing a user authentication and an encryption for a corresponding at least one FA in the network entry.

13. The communication method of claim 12, wherein the authentication is performed according to an Extensible Authentication Protocol (EAP).

14. The communication method of claim 8, further comprising:

distributing packets generated using the IP address to a plurality of FAs;

performing a MAC layer processing on the classified packets on the at least one FA basis;

converting a bit stream provided from processors to a signal; and

up-converting the signal to a band of the corresponding at least one FA and transmitting the signal.

15. An apparatus for communicating in a wireless communication system, the apparatus comprising:

means for loading one of Media Access Control (MAC) addresses for a multi-Frequency Allocation (FA) connection;

means for registering the loaded MAC address in an upper layer of a MAC layer; and

means for acquiring an Internet Protocol (IP) address using the registered MAC address when a network entry is complete.
