A method of configuring and registering an Internet Protocol (IPv6) address in a wireless mobile communication system having a connection-oriented radio link is provided. In an IP configuration method without Duplicate Address Detection (DAD), a Mobile Station (MS) is allocated a unique Connection Identifier (CID) specific to the MS from a serving Base Station (BS), and the MS and BS configure the IPv6 address independently using a known network prefix, a Medium Access Control (MAC) address of the MS, and the allocated CID. The BS registers the configured IPv6 address to a HA on behalf of MS.

What is claimed is: 1. A method of configuring an Internet Protocol (IPv6) address without Duplicate Address Detection (DAD) in a Mobile Station (MS) in a wireless mobile communication system having a connection-oriented radio link, the method comprising: allocating a Connection Identifier (CID) specific to an MS from a serving Base Station (BS); and configuring a Care of Address (CoA) IP address using a known network prefix, a Medium Access Control (MAC) address of the MS, and the allocated CID. 2. The method of claim 1, further comprising receiving the CID in a ranging response message from the serving BS. 3. The method of claim 2, wherein the receiving of the CID comprises receiving a basic CID or a primary management CID. 4. The method of claim 1, further comprising receiving the network prefix, included in a routing advertisement message, from the serving BS. 5. A method of receiving a Home of Address (HoA) in a Mobile Station (MS) in a wireless mobile communication system having a connection-oriented radio link, the method comprising: sending, by the MS, a message including an indicator indicating whether the MS has an HoA to a serving Base Station (BS) selected for initial network entry; and receiving, by the MS, the HoA from the serving BS, if the indication indicates that the MS has no HoA; wherein a value of the indicator is ‘0’ if the MS has no HoA, and the value of the indicator is ‘1’ if the MS has the HoA. 6. The method of claim 5, further comprising requesting HoA registration to the serving BS, if the indicator indicates that the MS has the HoA. 7. The method of claim 5, wherein the sending of the message comprises sending a ranging request message. 8. A method of configuring an Internet Protocol (IPv6) address without Duplicate Address Detection (DAD) during handover in a Mobile Station (MS) in a wireless mobile communication system having a connection-oriented radio link, the method comprising: deciding on a handover from an old serving Base Station (BS) to a target BS; sending a ranging request message including a Medium Access Control (MAC) address of the MS and information indicating the handover to the target BS; allocating a Connection Identifier (CID) specific to the MS from the target BS; receiving a routing advertisement message including a network prefix from the target BS; and configuring a Care of Address (CoA) IP address using the network prefix, the MAC address of the MS, and the allocated CID. 9. The method of claim 8, wherein the deciding on the handover comprises deciding on the handover upon request of the serving BS. 10. The method of claim 8, wherein the CoA comprises a 128-bit Internet Protocol version 6 (IPv6) address that is temporarily used when the MS moves from one subnet to another subnet. 11. A method of configuring an Internet Protocol (IPv6) address without Duplicate Address Detection (DAD) in a serving Base Station (BS) in a wireless mobile communication system having a connection-oriented radio link, the method comprising: receiving a Medium Access Control (MAC) address of a Mobile Station (MS) from the MS; and configuring a Care of Address (CoA) IP address using a network prefix, the MAC address, and a Connection Identifier (CID) allocated to the MS. 12. The method of claim 11, further comprising receiving the MAC address and an indication indicating whether the MS has a Home of Address (HoA) IP address in a ranging request message from the MS. 13. The method of claim 12, further comprising: requesting allocation of the HoA to an authentication server if the indication indicates that the MS does not have the HoA; receiving the HoA from the authentication server and registering the HoA and the CoA to an HA on the behalf of the MS through an embedded BU-REQ message; and notifying the MS of the HoA. 14. The method of claim 12, further comprising registering the HoA and the CoA of the MS by sending an BU-REQ message after receiving the HoA, if the indication indicates that the MS has the HoA. 15. The method of claim 11, further comprising sending the HoA to a target BS for handover of the MS, if the serving BS decides on a handover on its own or upon request of the MS. 16. A method of configuring an Internet Protocol (IPv6) address without Duplicate Address Detection (DAD) in a wireless mobile communication system having a connection-oriented radio link, the method comprising: sending a Medium Access Control (MAC) address of a Mobile Station (MS) to a serving Base Station (BS) by the MS; configuring, by the serving BS, a Care of Address (CoA) IPv6 address using a network prefix, the MAC address, and a Connection Identifier (CID) allocated to the MS by the serving BS; and configuring, by the MS, upon receipt of the network prefix, the CoA using the network prefix, the MAC address, and the CID.
