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, the terminal comprising:

a transceiver; and

at least one processor coupled to the transceiver,

wherein the at least one processor is configured to;

generate an internet protocol (IP) address of the terminal based on a first media access control (MAC) address among a plurality of MAC addresses respectively allocated for a plurality of frequency bands;

generate IP packets in which the IP address is included;

generate, based on a first subset of the IP packets, first MAC packets in which the first MAC address is included;

generate, based on a second subset of the IP packets, second MAC packets in which a second MAC address among the plurality of MAC addresses is included; and

control to transmit the first MAC packets on a first frequency band among the plurality of frequency bands and the second MAC packets on a second frequency band among the plurality of frequency bands.

2. The terminal of claim 1, further comprising:

a driver configured to load one of the plurality of MAC addresses of the terminal for the plurality of frequency bands when the terminal is initialized;

an interface configured to register the loaded MAC address to use in an upper layer of a MAC layer;

a manager configured to acquire the IP address for the plurality of MAC addresses of the terminal using the registered MAC address, when a network entry for the plurality of frequency bands is completed.

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

wherein the first MAC address is the one MAC address.

4. The terminal of claim 2, further comprising:

a plurality of authentication modules for performing a user authentication and an encryption for a corresponding frequency band in the network entry.

5. A method for operating a terminal in a wireless communication system, the method comprising:

generating an internet protocol (IP) address of the terminal based on a first media access control (MAC) address among a plurality of MAC addresses respectively allocated for a plurality of frequeny band;

generating IP packets in which the IP address is included;

generating, based on a first subset of the IP packets, first MAC packets in which the first MAC address is included;

generating, based on a second subset of the IP packets, second MAC packets in which a second MAC address among the plurality of MAC addresses is included; and

transmitting the first MAC packets on a first frequency band and the second MAC packets on a second frequency band.

6. The method of claim 5, further comprising:

loading one of the plurality of MAC addresses of the terminal for the plurality of frequency bands when the terminal is initialized;

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

acquiring the IP address for the plurality of MAC addresses of the terminal using the registered MAC address, when a network entry for the plurality of frequency bands is completed.

7. The method of claim 6, wherein the one MAC address is preset as a default MAC address, and

wherein the first MAC address is the one MAC address.

8. The method of claim 6, further comprising:

performing a user authentication and an encryption for a corresponding frequency band in the network entry.
