Abstract
A first network element determines (11) that a given mobile node using mobile Internet Protocol should receive subsequent broadcast packets as may be sourced by a corresponding Home Agent. This first network element can then determine (12) whether to support such subsequent broadcast packets using a first broadcast packet handling approach or a second broadcast packet handling approach.
Claims42
A method comprising:
- determining at a first network element that a given mobile node using mobile Internet Protocol should receive subsequent broadcast packets as sourced by a corresponding Home Agent;
- automatically determining whether to support such subsequent broadcast packets using a first broadcast packet handling approach or a second broadcast packet handling approach.
A method for use by a first network node, comprising:
- determining that a given mobile node using mobile Internet Protocol should receive subsequent broadcast packets as sourced by a corresponding Home Agent;
- automatically determining whether to support such subsequent broadcast packets using a first broadcast packet handling approach or a second broadcast packet handling approach by conducting negotiations with the Home Agent regarding broadcast packet handling.
A method for use by a Home Agent comprising:
- receiving an indication from a first network element that a given mobile node using mobile Internet Protocol should receive subsequent broadcast packets as sourced by the Home Agent;
- automatically determining whether to support such subsequent broadcast packets using a first broadcast packet handling approach or a second broadcast packet handling approach.
An apparatus comprising:
- an interface to a mobile Internet Protocol-compatible wireless mobile node;
- an interface to a Home Agent;
- a list indicating whether to use a first broadcast packet handling approach or a second broadcast packet handling approach when forwarding broadcast packets from the Home Agent to the mobile node;
- a controller operably coupled to the interface to the mobile node, the interface to the Home Agent, and the list.
