Abstract
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.
Claims16
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.
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.
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.
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.
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.
