Patent ID: 7917152

Claim:
A method, comprising: sending, from a mobile entity to a second network access entity, a message comprising a fast binding update message, the message including information for identifying a first network access entity comprising a gateway general packet radio service support node, wherein the information identifying the first network access entity enables the second network access entity to determine a global address for the first network access entity, wherein the global address of the first network access entity is not known to the mobile entity due to a move by the mobile entity from a previous network to a target network of the second network access entity, wherein the information comprises a link local address associated with the first network access entity, a network identity associated with the previous network of the first network access entity, an access point name associated with an access point through which the mobile entity was connected to the first network access entity, and a link layer address of the mobile entity; and handing over a connection of the mobile entity from the first network access entity to the second network access entity, wherein the message is configured to enable the second network access entity to direct traffic to the first network access entity based on the information included in the message, wherein the information is mapped, at the second network access entity, to the global address of the first network access entity.
