US 2004/0063402 A1 · Method and apparatus for mobile communication utilizing load balancing

Abstract

A method and apparatus are provided for mobile communication utilizing load balancing. When a home agent (HA) consists of one or more servers with each server being assigned a Mobile IPv6 Home-Agents Anycast Address, a nearby router does not store the link-layer addresses with respect to the Anycast addresses of the servers in its neighbor cache. Consequently, load balancing between or among the servers could not be performed. To solve this problem, in one example, an HA is provided that comprises a representative HA and distributed HAs. The representative HA is assigned an Anycast Address. The representative HA includes a collecting device configured to collect HA lists and load information from the distributed HAs. The representative HA dynamically creates a HA list and sends the HA list to a mobile node (MN). The MN registers its current location with an HA from the HA list included in a Home Agent Address Discovery Reply message. The load on the HA can then be shared by the servers constituting the HA.

Dependent claims

A server in a first network compliant with a protocol, the server comprising:

a first information processing equipment including a representative function and an interface having an address indicating a group of interfaces;
a second information processing equipment without the representative function, wherein the first information processing equipment further includes a collecting device configured to collect attribute and load information from the second information processing equipment, wherein the second information processing equipment includes a storing device configured to store information corresponding to an address acquired by terminal equipment in a second network compliant with the protocol and to an address assigned to terminal equipment in the first network, wherein the first information processing equipment further includes a listing device configured to generate list information from the attribute and load information collected from the second information processing equipment and a sending device configured to send the list information the terminal equipment when the server receives a message addressed to the address indicating the group of interfaces.

A method for mobile communication for a server in a first network compliant with a protocol, wherein the server includes a first information processing equipment with a function and a second information processing equipment without the function, wherein the first information processing equipment includes an interface having an address indicating a group of interfaces, the method comprising:

collecting attribute and load information from the second information processing equipment;
storing information corresponding to an address acquired by terminal equipment in a second network compliant with the protocol and to an address assigned to terminal equipment in the first network;
generating list information from the attribute and load information collected from the second information processing equipment;
receiving a message addressed to the address indicating the group of interfaces;
and
sending the list information.
