Abstract
A system is provided for prefix delegation with a pre-configured home agent, having a home address, and having a set of mobile router prefixes that are available to delegate to mobile routers. The transceiver of the home agent receives a prefix request option from a mobile router to request a prefix. The home agent assigns a prefix by combining a selected one of the set of mobile router prefixes with at least a part of the home address of the home agent, and sends the assigned prefix to the mobile router. Alternatively, the home agent assigns a prefix by combining a selected one of the set of mobile router prefixes with at least a part of the home address of the mobile router, and sends the assigned prefix to the mobile router.

A method for prefix delegation, comprising:
- pre-configuring a home agent, having a home address, with a set of mobile router prefixes that are available to delegate;
- receiving a prefix request option from a mobile router to request a prefix, the mobile router having a home address;
- and
- assigning a prefix,
- wherein the step of assigning the prefix comprises combining a selected one of the set of mobile router prefixes with at least a part of one of said home addresses.
A mobile router, comprising
- a home address for the mobile router;
- a transceiver for sending a prefix request option to a home agent to request a prefix, the home agent having a home address, the transceiver further for receiving a prefix delegation containing an assigned prefix;
- and
- a processor for configuring the mobile router for using the assigned prefix, wherein the assigned prefix comprises a selected one of a set of pre-configured mobile router prefixes combined with at least a part of one of said home addresses home address.
An apparatus for prefix delegation, comprising:
- a home agent, having a home address and a set of mobile router prefixes that are available to delegate to mobile routers;
- a transceiver for receiving a prefix request option from a mobile router to request a prefix, the mobile router having a home address, the transceiver further for sending the assigning a prefix;
- and
- a processor to assign the prefix by combining a selected one of the set of mobile router prefixes with at least of part of one of said home addresses.
An apparatus for prefix delegation, comprising:
- means for providing a home address and a set of mobile router prefixes that are available to delegate to mobile routers;
- means for receiving a prefix request option from a mobile router to request a prefix, the mobile router having a home address, the means for receiving further for sending the assigning a prefix;
- and
- means for assigning the prefix by combining a selected one of the set of mobile router prefixes with at least of part of one of said home addresses.
