Abstract

In various embodiments, communication apparatuses and methods for providing robust communications are disclosed. For example, an apparatus may establish an air interface in accordance with an orthogonal frequency division multiplex (OFDM) protocol. According to another particular aspect, the apparatus establishes an air interface in accordance with a Fast Low-Latency Access with Seamless Handoff Orthogonal Frequency Division Multiplex (FLASH-OFDM) protocol.

Claims (41)

1. A method for orthogonal frequency division multiplex (OFDM) address allocation in a wireless communication system, the method comprising:

establishing an air interface with an external host;

establishing network access with the external host;

establishing a Hierarchical Mobile IPv6 (HMIPv6) registration, including at least one care-of-address (CoA); and

sending a message including a handover alert (HAA) option, the HAA option including the following information:

a flag (S) indicating a receiver of a binding update (BU) message as a current external communication station,

a flag (D) indicating that the receiver as a new external communication station,

an other identifier field providing an IP address, capable of mapping to an IP address or providing an identification resolvable to an IP address, and

an action field describing at least purpose of the information in the message.

2. The method of claim 1 , wherein establishing the air interface includes communicating in accordance with a Fast Low-Latency Access with Seamless Handoff Orthogonal Frequency Division Multiplex (FLASH-OFDM) protocol; and

wherein the registration includes at least one on-link care-of address (LCoA).

3. The method of claim 1 , further comprising:

providing the message authentication code after a successful extended authentication protocol (EAP) authentication with a local domain;

using the authentication code to secure at least a subset of further BU messages;

determining a requirement for a dynamic assignment of a home agent and home address in one of a per-session basis and a per-mobile node power-up basis; and

using a network access identifier (NAI) and a security association with authentication, authorization, and accounting (AAA), the security association created by one of an out-of-band mechanism or IPv6 signaling.

4. A non-transitory machine-readable medium comprising instructions which, when executed by a machine, cause the machine to:

establish an air interface with an external host;

establish network access with the external host;

establish a Hierarchical Mobile IPv6 (HMIPv6) registration, including at least one care-of-address (CoA); and

send a message including a handover alert (HAA) option, the HAA option including the following information:

a flag (S) indicating a receiver of a binding update (BU) message as a current external communication station,

a flag (D) indicating that the receiver as a new external communication station,

another identifier field providing an IP address, capable of mapping to an IP address or providing an identification resolvable to an IP address, and

an action field describing at least purpose of the information in the message.

5. A base station for use in a wireless communication system, comprising:

at least one processor configured to:

establish an air interface with an external host;

establish network access with the external host;

establish a Hierarchical Mobile IPv6 (HMIPv6) registration, including at least one care-of-address (CoA); and

send a message including a handover alert (HAA) option, the HAA option including the following information:

a flag (S) indicating a receiver of a binding update (BU) message as a current external communication station,

a flag (D) indicating that the receiver as a new external communication station,

an other identifier field providing an IP address, capable of mapping to an IP address or providing an identification resolvable to an IP address, and

an action field describing at least purpose of the information in the message; and

memory coupled to said at least one processor.

6. The base station of claim 5 , wherein said at least one processor is further configured to:

provide the message authentication code after a successful extended authentication protocol (EAP) authentication with a local domain;

use the authentication code to secure at least a subset of further BU messages;

determine a requirement for a dynamic assignment of a home agent and home address in one of a per-session basis and a per-mobile node power-up basis; and

use a network access identifier (NAI) and a security association with authentication, authorization, and accounting (AAA), the security association created by one of an out-of-band mechanism or IPv6 signaling.
