A method of mobility management in a label-switched network comprising a primary domain comprising N label-switched nodes, with N>1, and a mobile domain comprising M mobile label-switched nodes, with M≧1, the mobile domain being movable with respect to said primary domain, packets routing between the primary domain and the mobile domain being performed by means of a primary border node, selected from the N label-switched nodes, and a mobile border node, selected from the M mobile label-switched nodes, wherein a handoff procedure is executed that establishes a label switched connection between the primary border node and the mobile border node. |

1. A method of mobility management in a label-switched network comprising a primary domain comprising N label-switched nodes, with N>1, and a mobile domain comprising M mobile label-switched nodes, with M≧1, the mobile domain being movable with respect to said primary domain, packets routing between the primary domain and the mobile domain being performed by means of a primary border node, selected from the N label-switched nodes, and a mobile border node, selected from the M mobile label-switched nodes, wherein a handoff procedure is executed, establishing a label switched connection between the primary border node and the mobile border node, the method comprising the steps of:
at the mobile border node, sending a request message to the primary border node, the request message comprising M′ labels adapted to enable the primary border node to form label switched paths from the primary border node to M′ of the M mobile label-switched nodes, via the mobile border node, with M′ being an integer, between 1 and M, inclusive; upon the receipt of said request message, the by primary border node, sends sending a response message to the mobile border node, the response message comprising N′ labels adapted to enable the mobile border node to form label switched paths from the mobile border node to N′ of the N label-switched nodes, via the primary border node, with N′ being an integer, between 1 and N, inclusive; at the receipt of said request message, the primary border node also sending a notify message comprising M′ stacking labels, allocated to the M′ mobile label-switched nodes, to at least one of said N′ label-switched nodes; wherein, when M>1, at the receipt of said response message, the mobile border node sending a notify message comprising N′ stacking labels, allocated to said N′ label-switched nodes, to at least one of the M′ mobile label-switched nodes. |
